Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Chapter 173-303 WAC implements chapter 70.105 RCW and Subtitle C of the federal Resource Conservation and Recovery Act (RCRA). Chapter 70.105 RCW provides authority to adopt regulations for dangerous waste management. The term dangerous waste includes more wastes than are in the federal hazardous waste definition because Washington's rules are more protective. The department of ecology (ecology) proposes to amend specific sections of the dangerous waste regulations to incorporate new federal hazardous waste rules, including but not limited to:
(1) Management Standards for Hazardous Waste Pharmaceuticals and Amendments to the P075 Listing for Nicotine. 84 F.R. 5816; February 22, 2019.
(2) Safe Management of Recalled Airbags. 83 F.R. 61552; November 30, 2018.
(3) User Fees for the Electronic Hazardous Waste Manifest System and Amendments to Manifest Regulations. 83 F.R. 420; January 3, 2018.
Proposed state-initiated amendments will also include:
(1) Corrections and clarifications to the generator improvements rule and other dangerous waste rules adopted January 28, 2019.
(2) Updating Biological Testing Methods for the Designation of Dangerous Waste publication 80-12.
(3) Other clarifications and corrections as necessary.
The purpose of this proposal is to clarify requirements, streamline compliance, and ensure that state dangerous wastes are properly and safely managed, which is a critical priority. Adoption of these federal regulations in Washington state will help promote compliance and safe management practices.
Reasons Supporting Proposal: Under federal law, ecology is required to adopt certain federal hazardous waste rules to maintain its authorization by the United States Environmental Protection Agency (EPA) and remain consistent with EPA regulations. Other new federal hazardous waste rules are optional for the state to adopt (for example, the recalled airbag rule and portions of the pharmaceutical rule). We are proposing some of the federal optional rules as part of this rule making. Adopting the required as well as the optional federal rules will promote better waste management, environmental protection, and consistency with the federal rules.
Washington state's healthcare stakeholders requested that we adopt the new federal pharmaceutical waste rules as soon as possible in order to help them better manage their waste streams, reduce confusion, and simplify compliance with the dangerous waste regulations.
These changes are:
(1) Hazardous waste pharmaceutical rule and amendments to the P075 Listing for Nicotine:
(a) Sets consistent, mandatory standards for healthcare facilities and reverse distributors across the nation.
(b) Prohibits disposal of pharmaceuticals down the drain, resulting in fewer toxic chemicals in our waterways.
(c) Removes over-the-counter nicotine replacement therapies, including nicotine-containing patches, gums, and lozenges, from being listed as P075 acutely hazardous waste when discarded. Because only a small amount of P-listed waste causes a generator to be regulated as a large quantity generator, the effect of delisting these discarded products may mean that some retail stores and pharmacies would be at a lower generator status.
(2) Safe management of recalled airbags:
(a) Provides regulatory relief to generators and transporters of airbag modules and inflators.
(b) Facilitates a more expedited removal of defective Takata airbag inflators from vehicles by Washington state dealerships, salvage yards, and other locations for safe and environmentally sound disposal.
(3) User fees and amendments for the electronic hazardous waste manifest system:
(a) Sets standards for determining electronic manifest user fees.
(b) Modifies some existing manifest regulations.
(c) Improves generator and state regulator access to the hazardous waste manifest system for tracking dangerous waste shipments.
(d) Is a required rule ecology must adopt to remain equivalent with federal regulations.
This rule making will also address state-initiated amendments that we believe will clarify and improve the existing regulations, including:
(1) Corrections and clarifications to the recent state dangerous waste rule amendments adopted January 28, 2019. As the new rules are being implemented, inspectors and the public have noted mistakes and unclear language needing correction.
(2) Updating the biological test methods publication will improve the static acute fish toxicity test, making it more usable and cost effective for how dangerous waste is identified. We also plan to remove the obsolete acute oral rat toxicity test method from the publication.
Other clarifications and corrections will improve the usability of the rules. One change ecology is proposing would modify a final facility permit rule (WAC 173-303-806(4)) to clarify certification requirements for submitted engineering documents.
Statutory Authority for Adoption: Chapter 70.105 RCW, Hazardous Waste Management Act.
Statute Being Implemented: Chapter 70.105 RCW.

This rule proposal, or portions of the proposal, is exempt from requirements of the Regulatory Fairness Act because the proposal:
Is exempt under RCW 19.85.025(4).
The proposed rule does not impose more-than-minor costs on businesses. Following is a summary of the agency's analysis showing how costs were calculated. The Regulatory Fairness Act (RFA; RCW 19.85.070) requires ecology to perform a set of analyses and make certain determinations regarding the proposed rule amendments, if they impose more than minor compliance costs on businesses. Based on the costs discussed in the Preliminary Regulatory Analyses (PRA) for this rule making (ecology publication no. 20-04-014), we identified the following compliance costs:
Adding recordkeeping requirements for the use of alternate tank inspection schedules: $36 to $39 per facility using an alternate schedule.
Adding container-labeling instructions for affixing, destroying, and ensuring readability of labels: $0.08 per label removed, necessitating at least one thousand two hundred sixteen labels removed and destroyed (rather than moved or replaced, as implied by baseline labeling requirements) to incur $100 of compliance cost. High numbers of label removals are unlikely, due to the requirement existing in other sections of the rule, as well as past requirements ecology recently revised with the accidental omission.
Increasing records retention for two types of records, by three to five years: Zero or near-zero cost relative to baseline space already retained and minimal management, and consistency with all other records retention requirements in the rule.
We also identified costs in the PRA related to noncompliance, which are excluded from consideration as compliance costs:
Allowing ecology discretion to obtain and approve of sampling plans.
Expanding the scope of kinds of reports that ecology may request from a generator.
For ecology, the RFA defines minor costs as "a cost per business that is less than three-tenths of one percent of annual revenue or income, or one hundred dollars, whichever is greater, or one percent of annual payroll." This means minor costs are less than either:
The larger of:
º$100.
º0.03 percent of annual revenue or income.
One percent of annual payroll.
As costs are likely less than $100, and are not necessarily imposed on the same businesses, they are less than minor costs, because regardless of annual revenue or income of potentially affected businesses:
If $100 is larger than 0.03 percent of annual revenue or income, likely costs are less than $100.
If $100 is less than 0.03 percent of annual revenue or income, and likely costs are less than $100, then likely compliance costs are less than 0.03 percent of annual revenue or income.
Due to the diverse set of industries covered by the rule, and uncertainty as to which businesses are using various existing flexible compliance options, we did not compare estimated compliance costs to payroll or revenue as industry averages would not have reflected facility-specific attributes in the comparisons. Therefore, RFA requirements do not apply to this rule making.

AMENDATORY SECTION(Amending WSR 04-24-065, filed 11/30/04, effective 1/1/05)
WAC 173-303-010Purpose.
This regulation implements chapter 70.105 RCW, the Hazardous Waste Management Act ((of 1976)) as amended, and implements, in part, chapters ((70.105A))70.95E, 70.105D, and 15.54 RCW, and Subtitle C of Public Law 94-580, the Resource Conservation and Recovery Act of 1976, which the legislature has empowered the department to implement. The purposes of this regulation are to:
(1) Designate those solid wastes which are dangerous or extremely hazardous to the public health and environment;
Note:
The terms public health and human health are used in this chapter interchangeably.
(2) Provide for surveillance and monitoring of dangerous and extremely hazardous wastes until they are detoxified, reclaimed, neutralized, or disposed of safely;
(3) Provide the form and rules necessary to establish a system for manifesting, tracking, reporting, monitoring, recordkeeping, sampling, and labeling dangerous and extremely hazardous wastes;
(4) Establish the siting, design, operation, closure, post-closure, financial, and monitoring requirements for dangerous and extremely hazardous waste transfer, treatment, storage, and disposal facilities;
(5) Establish design, operation, and monitoring requirements for managing the state's extremely hazardous waste disposal facility;
(6) Establish and administer a program for permitting dangerous and extremely hazardous waste management facilities; and
(7) Encourage recycling, reuse, reclamation, and recovery to the maximum extent possible.
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-017Recycling processes involving solid waste.
(1) The purpose of this section is to identify those materials that are and are not solid wastes when recycled. Certain materials, as described in subsection (2) of this section, would not typically be considered to involve waste management and are exempt from the requirements of this chapter. All recycling processes not exempted by subsection (2) of this section are subject to the recycling requirements of WAC 173-303-120.
(2) General categories of materials that are not solid waste when recycled.
(a) Except as provided in subsection (3) of this section, materials are not solid wastes when they can be shown to be recycled by being:
(i) Used or reused as ingredients in an industrial process to make a product provided the materials are not being reclaimed; or
(ii) Used or reused as effective substitutes for commercial products; or
(iii) Returned to the original process from which they are generated, without first being reclaimed or land disposed. The material must be returned as a substitute for feedstock materials. In cases where the original process to which the material is returned is a secondary process, the materials must be managed such that there is no placement on the land.
(b) Except as provided in subsection (3) of this section, the department has determined that the following materials when used as described are not solid wastes:
(i) Pulping liquors (e.g., black liquor) that are reclaimed in a pulping liquor recovery furnace and then reused in the pulping process;
(ii) Spent pickle liquor which is reused in wastewater treatment at a facility holding a national pollutant discharge elimination system (NPDES) permit, or which is being accumulated, stored, or treated before such reuse;
(iii) Spent sulfuric acid used to produce virgin sulfuric acid provided it is not accumulated speculatively as defined in WAC 173-303-016 (5)(d)(ii).
(3) The following materials are solid wastes, even if the recycling involves use, reuse, or return to the original process (as described in subsection (2)(a) of this section):
(a) Materials used in a manner constituting disposal, or used to produce products that are applied to the land; or
(b) Materials burned for energy recovery, used to produce a fuel, or contained in fuels; or
(c) Materials accumulated speculatively as defined in WAC 173-303-016 (5)(d)(ii); or
(d) Materials listed in WAC 173-303-016(6); or
(e) Any materials that the department determines are being accumulated, used, reused or handled in a manner that poses a threat to public health or the environment.
(4) Documentation of claims that materials are not solid wastes or are conditionally exempt from regulation. Respondents in actions to enforce regulations implementing chapter 70.105 RCW who raise a claim that a certain material is not a solid waste, or is conditionally exempt from regulation, must demonstrate that there is a known market or disposition for the material, and that they meet the terms of the exclusion or exemption. In doing so, they must provide appropriate documentation (such as contracts showing that a second person uses the material as an ingredient in a production process) to demonstrate that the material is not a waste, or is exempt from regulation. In addition, owners or operators of facilities claiming that they actually are recycling materials must show that they have the necessary equipment to do so.
(5) Variances from classification as a solid waste.
(a) In accordance with the standards and criteria in (b) of this subsection and the procedures in subsection (7) of this section, the department may determine on a case-by-case basis that the following recycled materials are not solid wastes:
(i) Materials that are accumulated speculatively without sufficient amounts being recycled (as defined in WAC 173-303-016 (5)(d)(ii));
(ii) Materials that are reclaimed and then reused within the original production process in which they were generated;
(iii) Materials that have been reclaimed but must be reclaimed further before the materials are completely recovered; and
(iv) ((Materials that are reclaimed in a continuous process;
(v) Materials that are indistinguishable in all relevant aspects from a product or intermediate; and
(vi))) State-only dangerous materials (not regulated as hazardous wastes (defined in WAC 173-303-040) by EPA) which serve as an effective substitute for a commercial product or raw material.
(b) Standards and criteria for variances from classification as a solid waste.
(i) The department may grant requests for a variance from classifying as a solid waste those materials that are accumulated speculatively without sufficient amounts being recycled if the applicant demonstrates that sufficient amounts of the material will be recycled or transferred for recycling in the following year. If a variance is granted, it is valid only for the following year, but can be renewed, on an annual basis, by filing a new application. The department's decision will be based on the following criteria:
(A) The manner in which the material is expected to be recycled, when the material is expected to be recycled, and whether this expected disposition is likely to occur (for example, because of past practice, market factors, the nature of the material, or contractual arrangements for recycling);
(B) The reason that the applicant has accumulated the material for one or more years without recycling seventy-five percent of the volume accumulated at the beginning of the year;
(C) The quantity of material already accumulated and the quantity expected to be generated and accumulated before the material is recycled;
(D) The extent to which the material is handled to minimize loss;
(E) Other relevant factors.
(ii) The department may grant requests for a variance from classifying as a solid waste those materials that are reclaimed and then reused as feedstock within the original production process in which the materials were generated if the reclamation operation is an essential part of the production process. This determination will be based on the following criteria:
(A) How economically viable the production process would be if it were to use virgin materials, rather than reclaimed materials;
(B) The extent to which the material is handled before reclamation to minimize loss;
(C) The time periods between generating the material and its reclamation, and between reclamation and return to the original primary production process;
(D) The location of the reclamation operation in relation to the production process;
(E) Whether the reclaimed material is used for the purpose for which it was originally produced when it is returned to the original process, and whether it is returned to the process in substantially its original form;
(F) Whether the person who generates the material also reclaims it;
(G) Other relevant factors.
(iii) The department may grant requests for a variance from classifying as a solid waste those hazardous secondary materials that have been partially reclaimed, but must be reclaimed further before recovery is completed, if the partial reclamation has produced a commodity-like material. A determination that a partially reclaimed hazardous secondary material for which the variance is sought is commodity-like will be based on whether the material is legitimately recycled as specified in WAC 173-303-019 and on whether all of the following decision criteria are satisfied:
(A) Whether the degree of partial reclamation the material has undergone is substantial as demonstrated by using a partial reclamation process other than the process that generated the dangerous waste;
(B) Whether the partially reclaimed material has sufficient economic value that it will be purchased for further reclamation;
(C) Whether the partially reclaimed material is a viable substitute for a product or intermediate produced from virgin or raw materials which is used in subsequent production steps;
(D) Whether there is a market for the partially reclaimed material as demonstrated by known customer(s) who are further reclaiming the material (e.g., records of sales and/or contracts and evidence of subsequent use, such as bills of lading);
(E) Whether the partially reclaimed material is handled to minimize loss; and
(F) Other relevant factors.
(iv) The department may grant requests for a variance from classifying as a solid waste those materials that serve as an effective substitute for a commercial product or raw material, when such material is not regulated as hazardous waste (defined in WAC 173-303-040) by EPA, if the materials are recycled in a manner such that they more closely resemble products or raw materials rather than wastes. This determination will be based on the following factors:
(A) The effectiveness of the material for the claimed use;
(B) The degree to which the material is like an analogous raw material or product;
(C) The extent to which the material is handled to minimize loss or escape to the environment;
(D) The extent to which an end market for the reclaimed material is guaranteed;
(E) The time period between generating the material and its recycling;
(F) Other factors as appropriate.
(6) Variance to be classified as a boiler.
In accordance with the standards and criteria in WAC 173-303-040 (definition of "boiler"), and the procedures in subsection (7) of this section, the department may determine on a case-by-case basis that certain enclosed devices using controlled flame combustion are boilers, even though they do not otherwise meet the definition of boiler contained in WAC 173-303-040, after considering the following criteria:
(a) The extent to which the unit has provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases; and
(b) The extent to which the combustion chamber and energy recovery equipment are of integral design; and
(c) The efficiency of energy recovery, calculated in terms of the recovered energy compared with the thermal value of the fuel; and
(d) The extent to which exported energy is utilized; and
(e) The extent to which the device is in common and customary use as a "boiler" functioning primarily to produce steam, heated fluids, or heated gases; and
(f) Other factors, as appropriate.
(7) Procedures for variances from classification as a solid waste or to be classified as a boiler.
The department will use the following procedures in evaluating applications for variances from classification as a solid waste or applications to classify particular enclosed controlled flame combustion devices as boilers:
(a) The applicant must apply to the department for the variance. The application must address the relevant criteria contained in subsection (5)(b) or (6) of this section, as applicable.
(b) The department will evaluate the application and issue a draft public notice tentatively granting or denying the application. Notification of this tentative decision will be provided by newspaper advertisement and radio broadcast in the locality where the recycler is located. The department will accept comment on the tentative decision for thirty days, and may also hold a public hearing upon request or at its discretion. The department will issue a final decision after receipt of comments and after the hearing (if any).
(c) In the event of a change in circumstances that affect how a material meets the relevant criteria contained in subsection (5) or (6) of this section, as applicable, upon which a variance has been based, the applicant must send a description of the change in circumstances to the department. The department may issue a determination that the material continues to meet the relevant criteria of the variance or may require the facility to reapply for the variance.
(d) Variances shall be effective for a fixed term not to exceed ten years. No later than six months prior to the end of this term, facilities must reapply for a variance. If a facility reapplies for a variance within six months, the facility may continue to operate under an expired variance until receiving a decision on their reapplication from the department.
(e) Facilities receiving a variance must provide notification as required by subsection (8) of this section.
(8) Notification requirements for materials managed under variances from classification as a solid waste.
(a) Facilities managing hazardous secondary materials under WAC 173-303-017(5) must send a notification prior to operating under the regulatory provision and by March 1st of each even-numbered year thereafter to the department using ecology's site identification form that includes the following information:
(i) The name, address, and EPA/state identification number (if applicable) of the facility;
(ii) The name and telephone number of a contact person;
(iii) The NAICS code of the facility;
(iv) The regulation under which the hazardous secondary materials will be managed;
(v) When the facility began or expects to begin managing the hazardous secondary materials in accordance with the regulation;
(vi) A list of hazardous secondary materials that will be managed according to the regulation (reported as the dangerous waste numbers that would apply if the hazardous secondary materials were managed as dangerous wastes);
(vii) The quantity of each hazardous secondary material to be managed annually; and
(viii) The certification (included in ecology's site identification form) signed and dated by an authorized representative of the facility.
(b) If a facility managing hazardous secondary materials under this section has submitted a notification, but then subsequently stops managing those materials in accordance with the regulation(s) listed above, the facility must notify the department within thirty days using ecology's site identification form. For purposes of this section, a facility has stopped managing hazardous secondary materials under this section if the facility no longer generates, manages, or reclaims materials under the regulation(s) above and does not expect to manage any amount of hazardous secondary materials under this section for at least one year.

WAC 173-303-040Definitions.
When used in this chapter, the following terms have the meanings given below.
Note:
The list of defined terms in this section does not contain all defined terms used in chapter 173-303 WAC.
"Aboveground tank" means a device meeting the definition of "tank" in this section and that is situated in such a way that the entire surface area of the tank is completely above the plane of the adjacent surrounding surface and the entire surface area of the tank (including the tank bottom) is able to be visually inspected.
"Accumulation" refers to the definition of "storage."
"Active life" of a facility means the period from the initial receipt of dangerous waste at the facility until the department receives certification of final closure.
"Active portion" means that portion of a facility which is not a closed portion, and where dangerous waste recycling, reuse, reclamation, transfer, treatment, storage or disposal operations are being or have been conducted after:
The effective date of the waste's designation by 40 C.F.R. Part 261; and
March 10, 1982, for wastes designated only by this chapter and not designated by 40 C.F.R. Part 261. (See also "closed portion" and "inactive portion.")
"Active range" means a military range that is currently in service and is being regularly used for range activities.
"Acute hazardous waste" means dangerous waste sources (listed in WAC 173-303-9904) F020, F021, F022, F023, F026, or F027, and discarded chemical products (listed in WAC 173-303-9903) that are identified with a dangerous waste number beginning with a "P", including those wastes mixed with source, special nuclear, or by-product material subject to the Atomic Energy Act of 1954. The abbreviation "AHW" will be used in this chapter to refer to those dangerous and mixed wastes which are acute hazardous wastes. Note - The terms acute and acutely are used interchangeably.
"Airbag waste" means any dangerous waste airbag modules or dangerous waste airbag inflators.
"Airbag waste collection facility" means any facility that receives airbag waste from airbag handlers subject to regulation under WAC 173-303-071 (3)(tt), and accumulates the waste for more than ten days.
"Airbag waste handler" means any person, by site, who generates airbag waste that is subject to the regulations under this chapter.
"Ampule" means an airtight vial made of glass, plastic, metal, or any combination of these materials.
"Ancillary equipment" means any device including, but not limited to, such devices as piping, fittings, flanges, valves, and pumps, that is used to distribute, meter, or control the flow of dangerous waste from its point of generation to a storage or treatment tank(s), between dangerous waste storage and treatment tanks to a point of disposal on site, or to a point of shipment for disposal off site.
"Aquifer" means a geologic formation, group of formations, or part of a formation capable of yielding a significant amount of groundwater to wells or springs.
"Authorized representative" means the person responsible for the overall operation of a generator site, facility, or an operational unit (e.g., plant manager, superintendent or an employee of the company of equivalent responsibility).
"Batch" means any waste which is generated less frequently than once a month.
"Battery" means a device consisting of one or more electrically connected electrochemical cells which is designed to receive, store, and deliver electric energy. An electrochemical cell is a system consisting of an anode, cathode, and an electrolyte, plus such connections (electrical and mechanical) as may be needed to allow the cell to deliver or receive electrical energy. The term battery also includes an intact, unbroken battery from which the electrolyte has been removed.
"Berm" means the shoulder of a dike.
"Boiler" means an enclosed device using controlled flame combustion and having the following characteristics:
The unit must have physical provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases; and
The unit's combustion chamber and primary energy recovery section(s) must be of integral design. To be of integral design, the combustion chamber and the primary energy recovery section(s) (such as waterwalls and superheaters) must be physically formed into one manufactured or assembled unit. A unit in which the combustion chamber and the primary energy recovery section(s) are joined only by ducts or connections carrying flue gas is not integrally designed; however, secondary energy recovery equipment (such as economizers or air preheaters) need not be physically formed into the same unit as the combustion chamber and the primary energy recovery section. The following units are not precluded from being boilers solely because they are not of integral design: Process heaters (units that transfer energy directly to a process stream), and fluidized bed combustion units; and
While in operation, the unit must maintain a thermal energy recovery efficiency of at least sixty percent, calculated in terms of the recovered energy compared with the thermal value of the fuel; and
The unit must export and utilize at least seventy-five percent of the recovered energy, calculated on an annual basis.

AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-070Designation of dangerous waste.
(1) Purpose and applicability.
(a) This section describes the procedures for determining whether or not a solid waste is DW or EHW.
(b) The procedures in this section are applicable to any person who generates, or discovers on their site, a solid waste, as defined in WAC 173-303-016 (including recyclable materials) that is not exempted or excluded by this chapter, or by the department, or who is directed to or must further designate waste by subsection (4) or (5) of this section. Any person who generates or discovers a solid waste on their site must make an accurate determination if that waste is a dangerous waste in order to ensure wastes are properly managed according to applicable dangerous waste regulations. A dangerous waste determination is made by following the designation procedures set forth in subsection (3) of this section. Any person who determines by these procedures that their waste is designated DW or EHW is subject to all applicable requirements of this chapter.
(2)(a) Except as provided ((at WAC 173-303-070 (2)))in (c) of this subsection, once a material has been determined to be a dangerous waste, then any solid waste generated from the recycling, treatment, storage, or disposal of that dangerous waste is a dangerous waste unless and until:
(i) The generator has been able to accurately describe the variability or uniformity of the waste over time, and has been able to obtain demonstration samples which are representative of the waste's variability or uniformity; and
(ii)(A) It does not exhibit any of the characteristics of WAC 173-303-090; however, wastes that exhibit a characteristic at the point of generation may still be subject to the requirements of WAC 173-303-140 (2)(a), even if they no longer exhibit a characteristic at the point of land disposal; and
(B) If it was a listed waste under WAC 173-303-080 through 173-303-083, it also has been exempted pursuant to WAC 173-303-910(3); or
(iii) If originally designated only through WAC 173-303-100, it does not meet any of the criteria of WAC 173-303-100. Such solid waste will include, but not be limited to, any sludge, spill residue, ash emission control dust, leachate, or precipitation runoff. Precipitation runoff will not be considered a dangerous waste if it can be shown that the runoff has not been contaminated with the dangerous waste, or that the runoff is adequately addressed under existing state laws (e.g., chapter 90.48 RCW), or that the runoff does not exhibit any of the criteria or characteristics described in WAC 173-303-100.
(b) Materials that are reclaimed from solid wastes and that are used beneficially (as provided in WAC 173-303-016 and 173-303-017) are not solid wastes and hence are not dangerous wastes under this section unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal.
(c)(i) A dangerous waste that is listed in WAC 173-303-081(1) or 173-303-082(1) solely because it exhibits one or more characteristics of ignitability as defined under WAC 173-303-090(5), corrosivity as defined under WAC 173-303-090(6), or reactivity as defined under WAC 173-303-090(7) is not a dangerous waste, if the waste no longer exhibits any characteristic of dangerous waste identified in WAC 173-303-090 or any criteria identified in WAC 173-303-100.
(ii) The exclusion described in (c)(i) of this subsection also pertains to:
(A) Any solid waste generated from treating, storing, or disposing of a dangerous waste listed in WAC 173-303-081(1) or 173-303-082(1) solely because it exhibits the characteristics of ignitability, corrosivity, or reactivity as regulated under (a) and (b) of this section.
(B) Wastes excluded under this section are subject to 40 C.F.R. Part 268, which is incorporated by reference at WAC 173-303-140 (2)(a) (as applicable), even if they no longer exhibit a characteristic at the point of land disposal.
(3) Designation procedures.
(a) The dangerous waste designation for each solid waste must begin promptly at the point of waste generation or upon the discovery of a solid waste on their site. This must be done before any dilution, mixing, or other alteration of the waste occurs, and at any time in the course of its management that it has, or may have, changed its properties as a result of exposure to the environment or other factors that may change the properties of the waste such that the solid waste or dangerous waste classification of the waste may change.
(b) A person must determine whether the solid waste is excluded from regulation under WAC 173-303-071.
(c) A person must check each section, in the order set forth in (d) of this subsection, to determine whether the waste is designated as a dangerous waste. When the waste is determined to be a dangerous waste following the steps in (d)(i) through (iii) of this subsection, further designation is not required except as required by subsection (4) or (5) of this section. If a person has checked the waste against each section and the waste is not designated, then the waste is not subject to the requirements of this chapter 173-303 WAC.
Any person who wishes to seek an exemption for a waste which has been designated DW or EHW must comply with the requirements of WAC 173-303-072.
(d) To determine whether or not a solid waste is designated as a dangerous waste a person must:
(i) First, determine if the waste is a listed discarded chemical product, WAC 173-303-081;
(ii) Second, determine if the waste is a listed dangerous waste source, WAC 173-303-082;
(iii) Third, determine if the waste also exhibits one or more dangerous waste characteristics, WAC 173-303-090; and
(iv) Fourth, if the waste is not listed in WAC 173-303-081 or 173-303-082, and does not exhibit a characteristic in WAC 173-303-090, determine if the waste meets one or more dangerous waste criteria, WAC 173-303-100.
(e) For the purpose of determining if a solid waste is a dangerous waste as identified in WAC 173-303-080 through 173-303-100, a person must either:
(i) Test the waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110; or
(ii) Apply knowledge of the waste in light of the materials or the process used, when:
(A) Such knowledge can be demonstrated to be sufficient for determining whether or not it designated and/or designated accurately; and
(B) All data and records supporting this determination in accordance with WAC 173-303-210(3) are retained on-site; and
(C) When available knowledge is inadequate or absent to make an accurate designation, the generator must test the waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110.
(f) Persons testing their waste must obtain a representative sample of the waste for the testing set forth in WAC 173-303-110.
(g) Test results from properly performed test methods specified in WAC 173-303-090 and 173-303-100 are definitive for determining the designation and regulatory status of the waste.
(4) Testing required. Notwithstanding any other provisions of this chapter, the department may require any person to test a waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110 to determine whether or not the waste is designated under the dangerous waste lists, characteristics, or criteria, WAC 173-303-080 through 173-303-100. Such testing may be required if the department has reason to believe that the waste would be designated DW or EHW by the dangerous waste lists, characteristics, or criteria, or if the department has reason to believe that the waste is designated improperly (e.g., the waste has been designated DW but should actually be designated EHW). The department may require persons to submit a waste analysis plan to, and receive written approval from, the department prior to testing a waste. If a person, pursuant to the requirements of this subsection, determines that the waste is a dangerous waste or that its designation must be changed, then they are subject to the applicable requirements of this chapter 173-303 WAC. The department will base a requirement to test a waste on evidence that includes, but is not limited to:
(a) Test information indicating that the person's waste may be DW or EHW;
(b) Evidence that the person's waste is very similar to another persons' already designated DW or EHW;
(c) Evidence that the persons' waste has historically been a DW or EHW;
(d) Evidence or information about a person's manufacturing materials or processes which indicate that the wastes may be DW or EHW; or
(e) Evidence that the knowledge or test results a person has regarding a waste is not sufficient for determining whether or not it designated and/or designated accurately.
(5) Additional designation required. A generator must manage dangerous waste under the most stringent management standards that apply. The following subsections describe how waste that has been designated as DW under the dangerous waste lists, WAC 173-303-080 through 173-303-082, or characteristics, WAC 173-303-090, or in the case of (c) of this subsection, under the lists, characteristics, or criteria, must be further designated under the dangerous waste criteria, WAC 173-303-100. This further designation under the criteria is necessary because it may change how the waste must be managed. Additional designation is required when:
(a) The waste is designated as DW with a QEL of 220 pounds and the generator otherwise qualifies as a small quantity generator. In this case, a generator must determine if their DW is also designated as a toxic EHW, WAC 173-303-100, with a QEL of 2.2 pounds; or
(b) The waste is designated as DW and the waste is to be discharged to a POTW operating under WAC 173-303-802(4) (Permits by rule). In this case, a generator must determine if the waste is also an EHW under WAC 173-303-100; or
(c) The waste is designated as a state-only DW and the waste is to be:
(i) Burned for energy recovery, as used oil, under the provisions of WAC 173-303-515; or
(ii) Land disposed within the state. In this case, a generator must determine if the waste is also an EHW under WAC 173-303-100.
(6) Dangerous waste numbers. When a person is designating, reporting, or keeping records on a dangerous waste, they must use all the dangerous waste numbers which they know are assignable to the waste from the dangerous waste lists, characteristics, or criteria. For example, if the waste is ignitable and contains more than 5 mg/l leachable lead when tested for the toxicity characteristic, they must use the dangerous waste numbers of D001 and D008. This will not be construed as requiring a person to designate their waste beyond those designation requirements set forth in subsections (2) through (5) of this section.
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-071Excluded categories of waste.
(1) Purpose. Certain categories of waste have been excluded from many of the requirements of chapter 173-303 WAC because they generally are not dangerous waste, are regulated under other state and federal programs, or are recycled in ways which do not threaten public health or the environment. WAC 173-303-071 describes these excluded categories of waste.
(2) Excluding wastes. Any persons who generate a common class of wastes and who seek to categorically exclude such class of wastes from the requirements of this chapter must comply with the applicable requirements of WAC 173-303-072. No waste class will be excluded if any of the wastes in the class are regulated as hazardous waste under 40 C.F.R. Part 261.
(3) Exclusions. The following categories of waste are excluded from the requirements of chapter 173-303 WAC, except for WAC 173-303-050, 173-303-145, and 173-303-960, and as otherwise specified:
(a)(i) Domestic sewage; and
(ii) Any mixture of domestic sewage and other wastes that passes through a sewer system to a publicly owned treatment works (POTW) for treatment, except as prohibited by WAC 173-303-555(6), provided:
(A) The generator or owner/operator has obtained a state waste discharge permit issued by the department, a temporary permit obtained pursuant to RCW 90.48.200, or pretreatment permit (or written discharge authorization) from a local sewage utility delegated pretreatment program responsibilities pursuant to RCW 90.48.165;
(B) The waste discharge is specifically authorized in a state waste discharge permit, pretreatment permit or written discharge authorization, or in the case of a temporary permit the waste is accurately described in the permit application;
(C) The waste discharge is not prohibited under 40 C.F.R. Part 403.5; and
(D) The waste prior to mixing with domestic sewage must not exhibit dangerous waste characteristics for ignitability, corrosivity, reactivity, or toxicity as defined in WAC 173-303-090, and must not meet the dangerous waste criteria for toxic dangerous waste or persistent dangerous waste under WAC 173-303-100, unless the waste is treatable in the publicly owned treatment works (POTW) where it will be received. This exclusion does not apply to the generation, treatment, storage, recycling, or other management of dangerous wastes prior to discharge into the sanitary sewage system;
(b) Industrial wastewater discharges that are point-source discharges subject to regulation under Section 402 of the Clean Water Act. This exclusion does not apply to the collection, storage, or treatment of industrial waste-waters prior to discharge, nor to sludges that are generated during industrial wastewater treatment. Owners or operators of certain wastewater treatment facilities managing dangerous wastes may qualify for a permit-by-rule pursuant to WAC 173-303-802(5);
(c) Household wastes, including household waste that has been collected, transported, stored, or disposed. Wastes that are residues from or are generated by the management of household wastes (e.g., leachate, ash from burning of refuse-derived fuel) are not excluded by this provision. "Household wastes" means any waste material (including, but not limited to, garbage, trash, and sanitary wastes in septic tanks) derived from households (including single and multiple residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic grounds, and day-use recreation areas). A resource recovery facility managing municipal solid waste will not be deemed to be treating, storing, disposing of, or otherwise managing dangerous wastes for the purposes of regulation under this chapter, if such facility:
(i) Receives and burns only:
(A) Household waste (from single and multiple dwellings, hotels, motels, and other residential sources); and
(B) Solid waste from commercial or industrial sources that does not contain dangerous waste; and
(ii) Such facility does not accept dangerous wastes and the owner or operator of such facility has established contractual requirements or other appropriate notification or inspection procedures to assure that dangerous wastes are not received at or burned in such facility;
(d) Agricultural crops and animal manures which are returned to the soil as fertilizers;
(e) Asphaltic materials designated only for the presence of PAHs by WAC 173-303-100(6). For the purposes of this exclusion, asphaltic materials means materials that have been used for structural and construction purposes (e.g., roads, dikes, paving) that were produced from mixtures of oil and sand, gravel, ash or similar substances;
(f) Roofing tars and shingles, except that these wastes are not excluded if mixed with wastes listed in WAC 173-303-081 or 173-303-082, or if they exhibit any of the characteristics specified in WAC 173-303-090;
(g) Treated wood waste and wood products including:
(i) Arsenical-treated wood that fails the test for the toxicity characteristic of WAC 173-303-090(8) (dangerous waste numbers D004 through D017 only) or that fails any state criteria, if the waste is generated by persons who utilize the arsenical-treated wood for the materials' intended end use. Intended end use means the wood products must have been used in typical treated wood applications (for example, fence posts, decking, poles, and timbers).
(ii) Wood treated with other preservatives provided such treated wood and wood waste (for example, sawdust and shavings) are, within one hundred eighty days after becoming waste:
(A) Disposed of at a landfill that is permitted in accordance with chapter 173-350 WAC, Solid waste handling standards, or chapter 173-351 WAC, criteria for municipal solid waste landfills, and provided that such wood is neither a listed waste under WAC 173-303-9903 and 173-303-9904 nor a TCLP waste under WAC 173-303-090(8); or
(B) Sent to a facility that will legitimately treat or recycle the treated wood waste, and manage any residue in accordance with that state's dangerous waste regulations; or
(C) Sent off-site to a permitted TSD facility or placed in an on-site facility which is permitted by the department under WAC 173-303-800 through 173-303-845. In addition, creosote-treated wood is excluded when burned for energy recovery in an industrial furnace or boiler that has an order of approval issued pursuant to RCW 70.94.152 by ecology or a local air pollution control authority to burn creosote treated wood.
(h) Irrigation return flows;
(i) (Reserved);
(j) Mining overburden returned to the mining site;
(k) Polychlorinated biphenyl (PCB) wastes:
(i) PCB containing dielectric fluid and electric equipment containing such fluid, and any PCB wastes meeting (k)(i)(B) of this subsection, whose disposal is regulated by EPA under 40 C.F.R. Part 761 (Toxic Substances Control Act) and that are dangerous either because:
(A) They fail the test for toxicity characteristic (WAC 173-303-090(8), Dangerous waste codes D018 through D043 only); or
(B) Because they are designated only by this chapter and not designated by 40 C.F.R. Part 261, are exempt from regulation under this chapter except for WAC 173-303-505 through 173-303-525, 173-303-960, those sections specified in subsection (3) of this section, and 40 C.F.R. Part 266;
(ii) Wastes that would be designated as dangerous waste under this chapter solely because they are listed as WPCB under WAC 173-303-9904 when such wastes are stored and disposed in a manner equivalent to the requirements of 40 C.F.R. Part 761, Subpart D for PCB concentrations of 50 ppm or greater.
(l) Samples:
(i) Except as provided in (l)(ii) and (iv) of this subsection, a sample of solid waste or a sample of water, soil, or air, which is collected for the sole purpose of testing to determine its characteristics or composition, is not subject to any requirements of this chapter, when:

WAC 173-303-073Conditional exclusion of special wastes.
(1) Purpose and applicability. Special wastes pose a relatively low hazard to human health and the environment. The department believes that special wastes can be safely managed with a level of protection that is intermediate between dangerous and nondangerous solid wastes. This section establishes a conditional exclusion for the management of special wastes. The definition for special waste is found in WAC 173-303-040.
(2) Exclusion. Special wastes are excluded from the requirements of chapter 173-303 WAC, except for WAC 173-303-050; 173-303-060; 173-303-140 (4)(c); 173-303-145; 173-303-960; and 173-303-510 excluding subsections (4)(a), (4)(b)(iii), (5), (6)(c), and (6)(d). In addition, special waste must be treated as dangerous waste for purposes of pollution prevention planning as required in chapters 173-307 and 173-305 WAC. Special wastes will not be considered as dangerous waste, provided they are managed in accordance with the standards in this subsection and provided they are disposed, legitimately recycled, or treated on-site consistent with the requirements of WAC 173-303-170 (((3)(c)))(2)(b)(v).
(a) Generators may not accumulate special waste on-site for more than one hundred eighty days from the date the quantity of waste exceeds two thousand two hundred pounds. The generator must keep a written record showing the dates when accumulation of the wastes began;
(b) During accumulation, special waste must be stored in a manner to prevent releases to the environment. This includes, but is not limited to, storing wastes in compatible containers, on impermeable surfaces, or in secondary containment structures, etc.;
(c) Facilities that receive special waste for recycling must meet the requirements of (b) of this subsection and store special wastes for no more than one hundred eighty days.
(d) All workers handling special wastes must be informed of the waste's potential hazard, either through worker training, health and safety plans, or notification of workers on a case-by-case basis;
(e) Special wastes must be transported directly from their site of generation to any off-site recycling, treatment, or disposal destination. The wastes must not pass through any intermediate solid waste processing facility, such as a transfer station, unless:
(i) The transfer station operator has made specific provisions for managing special waste by physical segregation, packing, or other means to ensure that workers and the public are not exposed to the waste stream at the transfer station;
(ii) The provisions are reflected in the facilities operating plans;
(iii) The plans have been approved by the transfer station's solid waste permitting authority;
(iv) The transfer station operator has informed workers of the wastes' potential hazard according to (d) of this subsection; and

(f) A document must accompany special waste during transit which identifies the type and amount of special waste, its place of origin, the identity of the generator, and the facility to which it is directed. An example form is provided in WAC 173-303-9906. The generator and the receiving facility must maintain a record of the facilities receipt of the special waste for at least five years;
(g) If a special waste being offered for transportation meets the definition of hazardous materials under 49 C.F.R. Parts 171 through 180, then the generator must package, label, mark and placard the shipment, and prepare the proper shipping papers in accordance with applicable Department of Transportation regulations in 49 C.F.R. Parts 172 through 180;
(h) Disposal of special waste must be in landfill units which:
(i) Are permitted in accordance with chapter 173-351 WAC, provided that an engineered liner with leachate collection is used to meet the alternative design requirements of WAC 173-351-300, or are permitted under WAC 173-303-800 through 173-303-840 or if out-of-state under 40 C.F.R. Part 258 or Part 270; and
(ii) Are not currently undergoing corrective action under WAC 173-351-440(7), 40 C.F.R. 258.56, or a similar requirement in state regulations approved by the United States EPA pursuant to 42 U.S.C. 6945 (c)(1)(B).

AMENDATORY SECTION(Amending WSR 15-01-123, filed 12/18/14, effective 1/18/15)
WAC 173-303-090Dangerous waste characteristics.
(1) Purpose. The purpose of this section is to set forth characteristics which a solid waste might exhibit and which would cause that waste to be a dangerous waste.
(2) Representative samples. The department will consider a sample obtained using any of the applicable sampling methods described in WAC 173-303-110(2), sampling and testing methods, to be a representative sample.
(3) Equivalent test methods. The testing methods specified in this section are the only acceptable methods, unless the department approves an equivalent test method in accordance with WAC 173-303-910(2).
(4) Quantity exclusion limit. A solid waste is a dangerous waste if it exhibits one or more of the dangerous waste characteristics described in subsections (5), (6), (7), and (8) of this section. If a person's solid waste exhibits one or more of these characteristics, then he or she is a dangerous waste generator (and may not be considered a small quantity generator as provided in WAC ((173-303-070(8)))173-303-170(2)) if the quantity of their waste exceeds 220 lbs. (100 kg) per month or per batch.
(5) Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative sample of the waste has any of the following properties:
(i) It is a liquid, other than an aqueous solution containing less than 24 percent alcohol by volume, and has a flash point less than 60 degrees C (140 degrees F), as determined by a Pensky-Martens Closed Cup Tester, using the test method specified in ASTM Standard D93-06, or a Setaflash Closed Cup Tester, using the test method specified in ASTM Standard D3278-96 (2004)e1 as incorporated by reference at WAC 173-303-110 (3)(h)(v) and (vi);
(ii) It is not a liquid and is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard;
(iii) It is an ignitable compressed gas.
(A) The term "compressed gas" applies to any material or mixture having in the container an absolute pressure exceeding 40 p.s.i. at 70 degrees F or, regardless of the pressure at 70 degrees F, having an absolute pressure exceeding 104 p.s.i. at 130 degrees F; or any liquid flammable material having a vapor pressure exceeding 40 p.s.i. absolute at 100 degrees F as determined by ASTM Test D-323.
(B) A compressed gas must be characterized as ignitable if any one of the following occurs:
(I) Either a mixture of 13 percent or less (by volume) with air forms a flammable mixture or the flammable range with air is wider than 12 percent regardless of the lower limit. These limits must be determined at atmospheric temperature and pressure. The method of sampling and test procedure must be acceptable to the Bureau of Explosives and approved by the director, Pipeline and Hazardous Materials Technology, U.S. Department of Transportation (see Note 2).
(II) Using the Bureau of Explosives' Flame Projection Apparatus (see Note 1), the flame projects more than 18 inches beyond the ignition source with valve opened fully, or the flame flashes back and burns at the valve with any degree of valve opening.
(III) Using the Bureau of Explosives' Open Drum Apparatus (see Note 1), there is any significant propagation of flame away from the ignition source.
(IV) Using the Bureau of Explosives' Closed Drum Apparatus (see Note 1), there is any explosion of the vapor-air mixture in the drum; or,
(iv) It is an oxidizer. An oxidizer for the purpose of this subsection is a substance such as a chlorate, permanganate, inorganic peroxide, or a nitrate, that yields oxygen readily to stimulate the combustion of organic matter (see Note 4).
An organic compound containing the bivalent -O-O-structure and which may be considered a derivative of hydrogen peroxide where one or more of the hydrogen atoms have been replaced by organic radicals must be classed as an organic peroxide unless:
(A) It is a forbidden explosive as defined in 49 C.F.R. 173.54, or a Class 1 explosive, Division 1.1, Division 1.2, Division 1.3, and Division 1.5, as defined in 49 C.F.R. 173.50, in which case it must be classed as an explosive;
(B) The material is forbidden to be offered for transportation according to 49 C.F.R. 172.101 and 49 C.F.R. 173.21;
(C) It is determined that the predominant hazard of the material containing an organic peroxide is other than that of an organic peroxide; or
(D) According to data on file with the Pipeline and Hazardous Materials Safety Administration in the U.S. Department of Transportation (see Note 3), it has been determined that the material does not present a hazard in transportation.

(i) It is aqueous and has a pH less than or equal to 2, or greater than or equal to 12.5, as determined by a pH meter using Method 9040C in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a);
(ii) It is liquid and corrodes steel (SAE 1020) at a rate greater than 0.250 inch (6.35 mm) per year at a test temperature of 55 degrees C (130 degrees F) as determined by the test method specified in NACE (National Association of Corrosion Engineers) Standard TM0169-2000 as standardized in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," (Method 1110A) EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a); or
(iii) It is solid or semisolid which, upon testing using Method 9045D in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods" (SW 846), results in a pH less than or equal to 2, or greater than or equal to 12.5.
(b) A solid waste that exhibits the characteristic of corrosivity because:
(i) It has either of the properties described in (a)(i) or (ii) of this subsection will be designated DW, and assigned the dangerous waste number of D002;
(ii) It only has the property described in (a)(iii) of this subsection will be designated DW, and assigned the dangerous waste number of WSC2.
(7) Characteristic of reactivity.
(a) A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties:
(i) It is normally unstable and readily undergoes violent change without detonating;
(ii) It reacts violently with water;
(iii) It forms potentially explosive mixtures with water;
(iv) When mixed with water, it generates toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment;
(v) It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5 can generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment;
(vi) It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement;
(vii) It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure; or
(viii) It is a forbidden explosive as defined in 49 C.F.R. 173.54, or a Class 1 explosive, Division 1.1, Division 1.2, Division 1.3, and Division 1.5, as defined in 49 C.F.R. 173.50 and 173.53.
(b) A solid waste that exhibits the characteristic of reactivity must be designated DW, and assigned the dangerous waste number of D003.
(8) Toxicity characteristic.
(a) A solid waste exhibits the characteristic of toxicity if, using the Toxicity Characteristic Leaching Procedure (TCLP), test Method 1311 in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a), the extract from a representative sample of the waste contains any of the contaminants listed in the toxicity characteristic list in (c) of this subsection, at concentrations equal to or greater than the respective value given in the list. When the waste contains less than 0.5 percent filterable solids, the waste itself, after filtering using the methodology outlined in Method 1311, is considered to be the extract for the purpose of this subsection.
(b) A solid waste that exhibits the toxicity characteristic has the dangerous waste number specified in the list which corresponds to the toxic contaminant causing it to be dangerous.
(c) Toxicity characteristic list. Any waste that contains contaminants which occur at concentrations at or above the DW threshold must be designated DW.

AMENDATORY SECTION(Amending WSR 15-01-123, filed 12/18/14, effective 1/18/15)
WAC 173-303-100Dangerous waste criteria.
(1) Purpose. The purpose of this section is to describe methods for determining if a solid waste is a dangerous waste by the criteria set forth in this section. The dangerous waste criteria consist of:
(a) Toxic dangerous wastes; and
(b) Persistent dangerous wastes.
(2) References. The following toxicity data sources are adopted by reference:
(a) The National Institute for Occupational Safety and Health's (NIOSH) Registry of Toxic Effects of Chemical Substances (RTECS), Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
(b) The United States Environmental Protection Agency, Ecotoxicology Database (ECOTOX), Mid-Continent Ecology Division, 6201 Congdon Boulevard, Duluth, MN 55804.
(c) The United States National Library of Medicine Toxicology Data Network, Hazardous Substance Database (HSDB), 8600 Rockville Pike, Bethesda, MD 20894.
(3) A person must use data that are available to him or her, and, when such data are inadequate for the purposes of this section, must refer to the references identified in WAC 173-303-100(2) to determine:
(a) Toxicity data or toxic category for each known constituent in the waste;
(b) Whether or not each known constituent of the waste is a halogenated organic compound or a polycyclic aromatic hydrocarbon as defined in WAC 173-303-040.
(4) Quantity exclusion limit. A solid waste is a dangerous waste if it meets one or more of the dangerous waste criteria described in subsections (5) and (6) of this section. If a person's solid waste meets one or more of these criteria then he or she is a dangerous waste generator (and may not be considered a small quantity generator as provided in WAC ((173-303-070(8)))173-303-170(2)) if the quantity of the waste exceeds the following quantity exclusion limits:
(a) For toxic dangerous wastes designated as EHW (WT01), the quantity exclusion limit is 2.2 lbs. per month.
(b) For any WT01 residue or contaminated soil, water, or other debris resulting from the clean up of a spill, into or on any land or water, the quantity exclusion limit is 220 lbs. per month.
(c) For all other wastes designating under this section the quantity exclusion limit is 220 lbs. (100 kg) per month or per batch.
(5) Toxicity criteria. Except as provided in WAC 173-303-070 (4) or (5), a person must determine if a solid waste meets the toxicity criteria under this section by following either the instructions for book designation, when his knowledge of the waste is sufficient, or by testing the waste using the biological testing methods adopted under WAC 173-303-110(3).
(a) Except as provided in WAC 173-303-070(4), if a person knows only some of the toxic constituents in the waste or only some of the constituent concentrations, and if the waste is undesignated for those known constituents or concentrations, then the waste is not designated for toxicity under this subsection.
(b) Book designation procedure. A person may determine if a waste meets the toxicity criteria by following the book designation instructions as follows:
(i) A person must determine the toxic category for each known constituent. The toxic category for each constituent may be determined from available data, for example, Registry for Toxic Effects of Chemical Substances (RTECS), Hazardous Substances Data Bank (HSDB), and Ecotoxicology database (ECOTOX). The toxic category should then be identified, using the table below. If data are available for more than one test endpoint (that is, fish, oral rat, inhalation rat, or dermal rabbit), the value with the highest toxicity must be used. Similarly, if toxicity data do not agree on the same toxic category within the same test endpoint, the value with the highest toxicity must be used.a Finally, if toxicity data for a constituent cannot be found in reasonably available sources (for example, RTECS, HSDB or ECOTOX), the toxic category for that constituent need not be determined.

These four test endpoints are defined in WAC 173-303-040.
 
b
Fish LC50 data must be derived from an exposure period greater than or equal to twenty-four hours. A hierarchy of species LC50 data should be used that includes (in decreasing order of preference) salmonids, fathead minnows, and other fish species.
 
c
Inhalation Rat LC50 data must be derived from an exposure period greater than or equal to one hour.
(ii) A person whose waste contains one or more toxic constituents must determine the equivalent concentration for the waste from the following formula:
Equivalent

∑A%

∑B%
+
∑C%

10,000
where ∑(X,A,B,C, or D)% is the sum of all the concentration percentages for a particular toxic category.
Example 1. A person's waste contains: Aldrin (A Category) - .01%; Endrin (A Category) - 1%; Benzene (D Category) - 4%; Phenol (C Category) - 2%; Dinoseb (B Category) - 5%; Water (nontoxic) - 87%. The equivalent concentration (E.C.) would be:
E.C. (%)
=

+
(0.01%+ 1.0%)

+
2.0%

10,000
 
=
0% + 0.101% + 0.05% + 0.002% + 0.0004% = 0.1534%
So the equivalent concentration equals 0.1534%.
(iii) A person whose waste contains toxic constituents must determine its designation according to the value of the equivalent concentration:
(A) If the equivalent concentration is less than 0.001%, the waste is not a toxic dangerous waste; or
(B) If the equivalent concentration is equal to or greater than 0.001% and less than 1.0%, the person will designate the waste as DW and assign the dangerous waste number WT02; and
(C) If the equivalent concentration is equal to or less than 0.01%, the DW may also be a special waste; or
(D) If the equivalent concentration is equal to or greater than 1.0%, the person will designate the waste as EHW and assign the dangerous waste number WT01.
Example 1. Continued. The equivalent concentration of 0.1534% (from Example 1. above) is greater than 0.001% and less than 1.0%. The waste is DW and the dangerous waste number WT02 must be assigned.
(iv) Reserve.
(c) Designation from bioassay data. A person may determine if a waste meets the toxicity criteria by following the bioassay designation instructions of either:
(i) The DW bioassay. To determine if a waste is DW, a person must establish the toxicity category range of a waste by means of the 100 mg/L acute static fish test ((or the 5000 mg/kg oral rat test)), as described in the biological testing methods (bioassay) adopted in WAC 173-303-110(3). If data from the test indicates that the waste is DW, then the person will assign the dangerous waste number WT02. Otherwise, the waste is not regulated as toxic dangerous waste. No further testing must be done except as provided in WAC 173-303-070 (4) and (5), or if the person chooses to determine whether the waste is EHW, or in the case of state-only solid dangerous waste, if the person chooses to determine whether the waste is special waste; or
(ii) The EHW and special waste bioassay. To determine if a waste is EHW, a person must establish the toxicity of a waste by means of the fish bioassay at 10 mg/L ((or the rat bioassay at 50 mg/Kg)), as described in the biological testing methods (bioassay) adopted in WAC 173-303-110(3). (NOTE: A fish bioassay at 1 mg/L corresponds with the definition of EHW, which includes toxic categories X-B. However, the fish bioassay is not reproducible at these low levels.) If data from the test indicates that the waste is EHW, then the person will assign the dangerous waste number WT01. Otherwise, the waste will be designated DW, and the person will assign the dangerous waste number WT02. A person with state-only solid waste may choose to test a waste to determine if it is special waste. Testing levels for special waste must be at 10 mg/L for the fish bioassay ((or 500 mg/Kg for the oral rat bioassay)). No further testing must be done except as provided in WAC 173-303-070 (4) and (5), or if the person chooses to test the waste in accordance with WAC 173-303-100 (5)(c)(i) to determine if the waste is not regulated as toxic dangerous waste.
(d) If the designation acquired from book designation and bioassay data do not agree, then bioassay data will be used to designate a waste. If a waste is designated as DW or EHW following the book designation procedure, a person may test the waste by means of the biological testing methods (bioassay) adopted under WAC 173-303-110(3)((, using either the static acute fish or the acute oral rat method,)) to demonstrate that the waste is not a dangerous waste or should be designated as DW and not EHW.
(e) A waste designated as DW by toxicity criteria must be assigned the dangerous waste number of WT02. A waste designated as EHW by toxicity criteria must be assigned the dangerous waste number of WT01.
(6) Persistence criteria. For the purposes of this section, persistent constituents are chemical compounds which are either halogenated organic compounds (HOC), or polycyclic aromatic hydrocarbons (PAH), as defined under WAC 173-303-040. Except as provided in WAC 173-303-070 (4) or (5), a person may determine the identity and concentration of persistent constituents by either applying knowledge of the waste or by testing the waste according to WAC 173-303-110 (3)(c) Chemical Testing Methods for Designating Dangerous Waste Publication #97-407.
(a) Except as provided in WAC 173-303-070(4), if a person knows only some of the persistent constituents in the waste, or only some of the constituent concentrations, and if the waste is undesignated for those known constituents or concentrations, then the waste is not designated for persistence under this subsection.
(b) When a waste contains one or more halogenated organic compounds (HOC) for which the concentrations are known, the total halogenated organic compound concentration must be determined by summing the concentration percentages for all of the halogenated organic compounds for which the concentration is known.
Example 2. A waste contains: Carbon tetrachloride - .009%; DDT - .012%; 1,1,1 - trichloroethylene - .020%. The total halogenated organic compound concentration would be:
Total HOC Concentration (%) = .009% + .012% +.020% =.041%
(c) A person whose waste contains polycyclic aromatic hydrocarbons (PAH) as defined in WAC 173-303-040, must determine the total PAH concentration by summing the concentration percentages of each of the polycyclic aromatic hydrocarbons for which they know the concentration.
Example 3. A person's waste contains: Chrysene - .08%; 3,4 - benzo(a)pyrene - 1.22%. The total polycyclic aromatic hydrocarbon concentration would be:
Total PAH Concentration (%) = .08% + 1.22% = 1.30%
(d) A person whose waste contains halogenated organic compounds and/or polycyclic aromatic hydrocarbons must determine its designation from the persistent dangerous waste table.

(7) "Ground-Water Monitoring List" Appendix IX to 40 C.F.R. Part 264 is replaced with the version in Appendix 5 of Chemical Test Methods for Designating Dangerous Waste, Department of Ecology Publication #97-407, revised December 2014. The Appendix "Ground-Water Monitoring List" in Chemical Testing Methods includes the columns "Suggested methods" and "PQL."
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-140Land disposal restrictions.
(1) Purpose.
(a) The purpose of this section is to encourage the best management practices for dangerous wastes according to the priorities of RCW 70.105.150 which are, in order of priority:
(i) Reduction;
(ii) Recycling;
(iii) Physical, chemical, and biological treatment;
(iv) Incineration;
(v) Stabilization and solidification; and
(vi) Landfill.
(b) This section identifies dangerous wastes that are restricted from land disposal, describes requirements for restricted wastes, and defines the circumstances under which a prohibited waste may continue to be land disposed.
(c) For the purposes of this section, the term "landfill," as stated in the priorities of RCW 70.105.150, will be the same as the term "land disposal." Land disposal will be used in this section to identify the lowest waste management priority.
(2) Applicability.
The land disposal restrictions of this section apply to any person who owns or operates a dangerous waste treatment, storage, or disposal facility in Washington state and to any person who generates or transports dangerous waste.
(a) Land disposal restrictions for wastes designated in accordance with WAC 173-303-070 (3)(((a)(i), (ii), and))(d)(i) through (iii) are the restrictions set forth by the Environmental Protection Agency in 40 C.F.R. Part 268 which are incorporated by reference into this regulation, as modified in (c) through (f) of this subsection, and the restrictions set forth in subsections (3) through (7) of this section. The words "regional administrator" (in 40 C.F.R.) will mean the "department," except for 40 C.F.R. Parts 268.5 and 268.6; 268 Subpart B; 268.42(b) and 268.44 (a) through (g). The authority for implementing these excluded C.F.R. sections remains with the U.S. Environmental Protection Agency. The word "EPA" (in 40 C.F.R.) means "Ecology" at 40 C.F.R. 268.44(m) and 268.45(a). The exemption and exception provisions of subsections (3) through (7) of this section are not applicable to the federal land disposal restrictions.
Where the federal regulations that have been incorporated by reference refer to 40 C.F.R. 260.11, data provided under this section must instead meet the requirements of WAC 173-303-110.
(b) Land disposal restrictions for state-only dangerous waste are the restrictions set forth in subsections (3) through (7) of this section.
(c) Where 40 C.F.R. 268.7 (a)(1) is incorporated by reference, delete the sentence "Alternatively, the generator must send the waste to a RCRA-permitted ((dangerous))hazardous waste treatment facility, where the waste treatment facility must comply with the requirements of 264.13 of this chapter and ((268.7))paragraph (b) of this section."
(d) Where 40 C.F.R. 268.7 (a)(2) is incorporated by reference:
(i) Delete the words "or if the generator chooses not to make the determination of whether their waste must be treated" from the first sentence; and
(ii) Delete the sentence "(Alternatively, if the generator chooses not to make the determination of whether the waste must be treated, the notification must include the EPA Hazardous Waste Numbers and Manifest Number of the first shipment and must state 'This hazardous waste may or may not be subject to the LDR treatment standards. The treatment facility must make the determination'.)"
(e) Where 40 C.F.R. 268.7 (b)(6) is incorporated by reference, replace the words "for the initial shipment of waste, prepare a one-time certification described in paragraph (b)(4) of this section, and a one-time notice which includes the information in paragraph (b)(3) of this section (except the manifest number)" with the words "submit a certification described in paragraph (b)(4) of this section, and a notice which includes the information listed in paragraph (b)(3) of this section (except for the manifest number) to the department for each shipment".
(f) Where 40 C.F.R. 268.9(d) is incorporated by reference, replace paragraph (d) with the following: Wastes that exhibit a characteristic are also subject to Section 268.7 requirements, except that once the waste is no longer dangerous, a one-time notification and certification must be placed in the generators or treaters files and sent to the department. The notification and certification that is placed in the generators or treaters files must be updated if the process or operation generating the waste changes and/or if the subtitle D facility receiving the waste changes. However, the generator or treater need only notify the department on an annual basis if such changes occur. Such notification and certification should be sent to the department by the end of the calendar year, but no later than December 31.
(i) The notification must include the following information:
(A) Name and address of the RCRA Subtitle D facility receiving the waste shipment; and
(B) A description of the waste as initially generated, including the applicable dangerous waste code(s), treatability group(s), and underlying hazardous constituents (as defined in Sec. 268.2(i)), unless the waste will be treated and monitored for all underlying hazardous constituents. If all underlying hazardous constituents will be treated and monitored, there is no requirement to list any of the underlying hazardous constituents on the notice.
(ii) The certification must be signed by an authorized representative and must state the language found in Section 268.7 (b)(4).
If treatment removes the characteristic but does not meet standards applicable to underlying hazardous constituents, then the certification found in Sec. 268.7 (b)(4)(iv) applies.
(3) Definitions.
When used in this section the following terms have the meaning provided in this subsection. All other terms have the meanings given under WAC 173-303-040.
(a) "Dangerous waste constituents" means those constituents listed in WAC 173-303-9905 and any other constituents which have caused a waste to be a dangerous waste under this chapter.
(b) "Land disposal" means placement in a facility or on the land with the intent of leaving the dangerous waste at closure, and includes, but is not limited to, placement for disposal purposes in a: Landfill; surface impoundment; waste pile; injection well; land treatment facility; salt dome or salt bed formation; underground cave or mine; concrete vault or bunker.
(c) "Organic/carbonaceous waste" means a dangerous waste that contains combined concentrations of greater than ten percent organic/carbonaceous constituents in the waste; organic/carbonaceous constituents are those substances that contain carbon-hydrogen, carbon-halogen, or carbon-carbon chemical bonding.
(d) "Solid acid waste" means a dangerous waste that exhibits the characteristic of low pH under the corrosivity test of WAC 173-303-090 (6)(a)(iii).
(e) "Stabilization" and "solidification" mean a technique that limits the solubility and mobility of dangerous waste constituents. Solidification immobilizes a waste through physical means and stabilization immobilizes the waste by bonding or chemically reacting with the stabilizing material.
(4) Land disposal restrictions and prohibitions. The land disposal requirements of this subsection apply to land disposal in Washington state.
(a) Disposal of extremely hazardous waste (EHW). No person may land dispose of EHW, except as provided in subsection (5) of this section, at any land disposal facility in the state. No person may land dispose of EHW at the facility established under RCW 70.105.050, except as provided by subsections (5), (6), and (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, neutralize, or otherwise process EHW to remove or reduce its harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter.
(b) Disposal of liquid waste. Special requirements for bulk and containerized liquids.
(i) The placement of bulk or noncontainerized liquid dangerous waste or dangerous waste containing free liquids (whether or not sorbents have been added) in any landfill is prohibited.
(ii) Containers holding free liquids must not be placed in a landfill unless:
(A) All free-standing liquid:
(I) Has been removed by decanting, or other methods; or
(II) Has been mixed with sorbent or stabilized (solidified) so that free-standing liquid is no longer observed; or
(III) Has been otherwise eliminated; or
(B) The container is very small, such as an ampule; or
(C) The container is designed to hold free liquids for use other than storage, such as a battery or capacitor; or
(D) The container is a labpack and is disposed of in accordance with WAC 173-303-161 and this chapter.
(iii) To demonstrate the absence or presence of free liquids in either a containerized or a bulk waste, the following tests must be used: Method 9095 (Paint Filter Liquids Test) as described in "Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods" EPA Publication SW-846 as incorporated by reference in WAC 173-303-110 (3)(a).
(iv) Sorbents used to treat free liquids to be disposed of in landfills must be nonbiodegradable. Nonbiodegradable sorbents are: Materials listed or described in (b)(iv)(A) of this subsection; materials that pass one of the tests in (b)(iv)(B) of this subsection; or materials that are determined by the department to be nonbiodegradable through WAC 173-303-910.
(A) Nonbiodegradable sorbents.
(I) Inorganic minerals, other inorganic materials, and elemental carbon (e.g., aluminosilicates, clays, smectites, Fuller's earth, bentonite, calcium bentonite, montmorillonite, calcined montmorillonite, kaolinite, micas (illite), vermiculites, zeolites; calcium carbonate (organic free limestone); oxides/hydroxides, alumina, lime, silica (sand), diatomaceous earth; perlite (volcanic glass); expanded volcanic rock; volcanic ash; cement kiln dust; fly ash; rice hull ash; activated charcoal/activated carbon); or
(II) High molecular weight synthetic polymers (e.g., polyethylene, high density polyethylene (HDPE), polypropylene, polystyrene, polyurethane, polyacrylate, polynorborene, polyisobutylene, ground synthetic rubber, cross-linked allylstyrene and tertiary butyl copolymers). This does not include polymers derived from biological material or polymers specifically designed to be degradable; or
(III) Mixtures of these nonbiodegradable materials.
(B) Tests for nonbiodegradable sorbents.
(I) The sorbent material is determined to be nonbiodegradable under ASTM Method G21-96 (2002) - Standard Practice for Determining Resistance of Synthetic Polymer Materials to Fungi; or
(II) The sorbent material is determined to be nonbiodegradable under OECD (Organization for Economic Cooperation and Development) test 301B: [CO2 Evolution (Modified Sturm Test)].
(v) The placement of any liquid which is not a dangerous waste in a landfill is prohibited unless the owner or operator of such landfill demonstrates to the department, or the department determines, that:
(A) The only reasonably available alternative to the placement in such landfill is placement in a landfill or unlined surface impoundment, whether or not permitted or operating under interim status, which contains, or may reasonably be anticipated to contain, hazardous waste; and
(B) Placement in such owner or operator's landfill will not present a risk of contamination of any underground source of drinking water (as that term is defined in WAC 173-303-040).
(c) Disposal of solid acid waste. No person may land dispose solid acid waste, except as provided in subsection (5), (6), or (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, neutralize, or otherwise process these wastes to remove or reduce their harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter.
(d) Disposal of organic/carbonaceous waste.
(i) No person may land dispose organic/carbonaceous waste, except as provided in subsection (5), (6), or (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, or otherwise process these wastes to remove or reduce their harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter. Organic/carbonaceous wastes must be incinerated as a minimum management method according to the dangerous waste management priorities as defined in subsection (1)(a) of this section.
(ii) This prohibition against the land disposal of organic/carbonaceous waste does not apply to black mud generated from the caustic leach recovery of cryolite at primary aluminum smelting plants.
(iii) This prohibition against the land disposal of organic/carbonaceous waste does not apply to any person who certifies to the department that recycling, treatment and incineration facilities are not available within a radius of one thousand miles from Washington state's borders. Such certification must be sent to the department by certified mail or other means that establish proof of receipt (including applicable electronic means) and must include: The name, address and telephone number of the person certifying; a brief description of the organic/carbonaceous waste covered by the certification; a discussion of the efforts undertaken to identify available recycling, treatment and incineration facilities; and the signature of the person responsible for the certification and development of information used to support the certification. Records and information supporting the certification must be retained by the certifying person and must be made available to the department upon request.
A certification that has been properly submitted to the department will remain valid until the department determines that a recycling, treatment or incineration facility is available within a radius of one thousand miles from Washington state's borders and the person who submitted the certification is unable to demonstrate otherwise. A recycling, treatment or incineration facility will be considered by the department to be available if such facility: Is operating, and; can safely and legally recycle, treat or incinerate the organic/carbonaceous waste, and; has sufficient capacity to receive and handle significant amounts of the waste, and; agrees to accept the waste.
(5) Treatment in land disposal facilities. The land disposal restrictions in subsection (4) of this section do not apply to persons treating dangerous wastes in surface impoundments, waste piles, or land treatment facilities provided that such treatment is performed in accordance with the requirements of this subsection and this chapter.
(a) Surface impoundment treatment.
Liquid waste, extremely hazardous waste (EHW), solid acid waste, and organic/carbonaceous waste may be placed in surface impoundments for purposes of treatment provided the owner/operator can demonstrate that effective treatment of the dangerous waste constituents will occur and at closure the owner/operator complies with the prohibitions and restrictions of subsection (4) of this section.
(b) Waste pile treatment.
Liquid waste, extremely hazardous waste (EHW), solid acid waste, and organic/carbonaceous waste may be placed in waste piles for purposes of treatment provided the owner/operator can demonstrate that effective treatment of dangerous waste constituents will occur and that at closure the owner/operator will be in compliance with the prohibitions and restrictions of subsection (4) of this section.
(c) Land treatment.
Liquid waste, extremely hazardous waste (EHW), and organic/carbonaceous waste may be land treated provided that the owner/operator can demonstrate that effective treatment of dangerous waste constituents will occur, and at the end of the post-closure care period the owner/operator will be in compliance with subsection (4) of this section.
(6) Case-by-case exemptions to a land disposal prohibition. Any person may petition the department for an exemption from a prohibition in subsection (4) of this section for the land disposal of a dangerous waste. The procedures to submit a petition to the department are specified in WAC 173-303-910(6). The department may deny any petition if it determines that there is a potential for dangerous waste constituents to migrate from the land disposal facility where the waste is to be placed. The department will deny any petition when exemption would result in a substantial or imminent threat to public health or the environment. The department will deny any petition when exemption would result in a violation of applicable state laws.
The department may grant an exemption from the prohibitions and restrictions of subsection (4) of this section based on the demonstrations specified in (a), (b) or (c) of this subsection.
(a) Land disposal exemption for treatment residuals. Any person may request an exemption from a land disposal prohibition in subsection (4) of this section for treatment residuals by demonstrating to the department that:
(i) The person has applied the best achievable management method to the original waste; and
(ii) Application of additional management methods to the treatment residuals would prevent the person from utilizing the best achievable management methods for the original dangerous waste; and
(iii) The land disposal of the treatment residuals does not pose a greater risk to the public health and the environment than land disposal of the original dangerous waste would pose.
(b) Economic hardship exemption. Any person may request an exemption from a prohibition in subsection (4) of this section for the land disposal of a dangerous waste by demonstrating to the department that alternative management of the dangerous waste will impose an unreasonable economic burden in relation to the threat of harm to public health and the environment. It will be solely within the discretion of the department to approve or deny the requests for exemptions based on economic hardship.
(c) Organic/carbonaceous waste exemption. Any person may request an exemption from the requirements in subsection (4) of this section by demonstrating to the department that:
(i) Alternative management methods for organic/carbonaceous waste are less protective of public health and the environment than stabilization or landfilling; or
(ii)(A) The organic/carbonaceous waste has a heat content less than 3,000 BTU/LB or contains greater than sixty-five percent water or other noncombustible moisture; and
(B) Incineration is the only management method available within a radius of one thousand miles from Washington state's border (i.e., recycling or treatment are not available).
(7) Emergency cleanup provision. The department may, on a case-by-case basis, grant an exception to the land disposal restrictions in subsection (4) of this section for an emergency cleanup where an imminent threat to public health and the environment exists. Any exception will require compliance with applicable state law and will require (consistent with the nature of the emergency and imminent threat) application of the waste management priorities of RCW 70.105.150.

WAC 173-303-141Treatment, storage, or disposal of dangerous waste.
(1) A person may offer, transport, transfer, or deliver a designated dangerous waste only to a TSD facility which is operating either: Under a permit issued pursuant to the requirements of this chapter; or, if the TSD facility is located outside of this state, under interim status or a permit issued by United States EPA under 40 C.F.R. Part 270, or under interim status or a permit issued by another state which has been authorized by United States EPA pursuant to 40 C.F.R. Part 271.
(2) A person may offer a state only designated dangerous waste (not regulated as a hazardous waste by EPA) to a facility which is located outside of this state and which does not meet the requirements of subsection (1) of this section if:
(a) The facility receiving the waste will legitimately treat or recycle the dangerous waste (disposal is an unacceptable management practice);
(b) The generator has on file a letter or copy of a letter signed by the regulatory authority in the receiving state that the receiving facility may accept the waste;
(c) The generator uses a transporter with a valid EPA/state identification number;
(d) The generator complies with all other applicable requirements, including manifesting, packaging and labeling, with respect to the shipping of the waste((. However, the EPA/state identification number for the receiving facility is not required on the manifest or annual report)); and
(e) The generator receives from the receiving facility a signed and dated copy of the manifest.
AMENDATORY SECTION(Amending WSR 09-14-105, filed 6/30/09, effective 7/31/09)
WAC 173-303-160Containers.
(1) Waste quantity. Containers and inner liners will not be considered as a part of the waste when measuring or calculating the quantity of a dangerous waste. Only the weight of the residues in nonempty or nonrinsed containers or inner liners will be considered when determining waste quantities.
(2) A container or inner liner is "empty" when:
(a) All wastes in it have been taken out that can be removed using practices commonly employed to remove materials from that type of container or inner liner (for example, pouring, pumping, aspirating, etc.) and:
(i) No more than one inch of waste remains at the bottom of the container or inner liner; or
(ii) No more than 3 percent by weight of the total capacity of the container remains in the container or inner liner if the container is less than or equal to 119 gallons in size; or
(iii) No more than 0.3 percent by weight of the total capacity of the container remains in the container or inner liner if the container is greater than 119 gallons in size.
A container that held compressed gas is empty when the pressure inside the container equals or nearly equals atmospheric pressure; and
(b) If the container or inner liner held acutely hazardous waste, as defined in WAC 173-303-040, toxic EHW as defined in WAC 173-303-100 or pesticides bearing the danger or warning label, the container or inner liner has been rinsed at least three times with an appropriate cleaner or solvent. The volume of cleaner or solvent used for each rinsing must be ten percent or more of the container's or inner liner's capacity or of sufficient quantity to thoroughly decontaminate the container. In lieu of rinsing for containers that might be damaged or made unusable by rinsing with liquids (for example, fiber or cardboard containers without inner liners), an empty container may be vacuum cleaned, struck, with the open end of the container up, three times (for example, on the ground, with a hammer or hand) to remove or loosen particles from the inner walls and corners, and vacuum cleaned again. Equipment used for the vacuum cleaning of residues from containers or inner liners must be decontaminated before discarding, in accordance with procedures approved by the department. A container or inner liner is also considered "empty" if the container or inner liner has been cleaned by another method that has been shown in the scientific literature, or by tests conducted by the generator, to achieve equivalent removal.
Any rinsate or vacuumed residue that results from the cleaning of containers or inner liners must, whenever possible, be reused in a manner consistent with the original intended purpose of the substance in the container or inner liner. In the case of a farmer, if the rinsate is a pesticide residue then the rinsate must be managed or reused in a manner consistent with the application instructions on the pesticide label. On-site disposal or burial of pesticide residues is prohibited. Otherwise, the rinsate must be checked against the designation requirements (WAC 173-303-070 through 173-303-100) and, if designated, managed according to the requirements of this chapter.
(c) In the case of a container, the inner liner, that prevented the container from contact with the commercial chemical product or manufacturing chemical, has been removed.
(3)(a) Any residues remaining in containers or inner liners that are "empty" as described in subsection (2) of this section will not be subject to the requirements of this chapter, and will not be considered as accumulated wastes for the purposes of calculating waste quantities.
(b) Any dangerous waste in either: A container that is not empty, or an inner liner removed from a container that is not empty (as defined in subsection (2) of this section) is subject to the requirements of this chapter.
(4) A person who cannot meet the provisions in (2)(b) of this section may petition the department to approve alternative container rinsing processes in accordance with WAC 173-303-910(1).
(5) Containers of dangerous waste pharmaceuticals are subject to WAC 173-303-555(8) for determining when they are considered empty, in lieu of this section, except as provided by WAC 173-303-555 (8)(c) and (d).
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-169Quantity exclusion limitsGenerator category determinations.
A generator must determine its generator category. A generator's category is based on the amount of dangerous waste generated each month and may change from month to month. This section sets forth procedures to determine whether a generator is a small quantity generator, a medium quantity generator, or a large quantity generator for a particular month, as defined in WAC 173-303-040.
(1) Quantity exclusion limits. In each of the designation sections describing the lists, characteristics, and criteria, quantity exclusion limits (QEL) are identified. The QEL is the quantity of dangerous waste generated in a calendar month used to distinguish when a dangerous waste is only subject to the small quantity generator provisions, the medium quantity generator provisions, or when a dangerous waste is subject to the large quantity generator provisions. Any solid waste (which is not excluded or exempted) that is listed, exhibits a characteristic, or meets the criteria of this chapter is a dangerous waste.
(2) Aggregated waste quantities.
(a) A person may be generating more than one kind of dangerous waste. In such cases, they must consider the aggregate quantity of their wastes when determining whether or not their waste amounts exceed the specific quantity exclusion limits (QEL) for waste generation;
(b) Waste quantities must be aggregated for all waste with common QELs. Example: If a person generates 100 pounds of an ignitable waste and 130 pounds of a persistent waste, then both wastes are regulated because the aggregate waste quantity (230 pounds) exceeds the common QEL of 220 pounds. On the other hand, if a person generates one pound of toxic EHW and 218 pounds of a corrosive waste, their quantities would not be aggregated because they do not share a common QEL (2.2 pounds and 220 pounds, respective QELs).
(3) Generator category determination.
(a) Determine separately the resulting generator categories for the quantities of waste with a 2.2 pound QEL and for the quantities of waste with a 220 pound QEL using Table 1 of this section; and
(b) Compare the resulting generator categories from (a) of this subsection and apply the more stringent generator category to the accumulation and management of dangerous waste with a 2.2 pound QEL and with a 220 pound QEL.

(4) When making the quantity determinations of this subsection and WAC 173-303-170 through 173-303-230, generators must include all dangerous wastes they generate, except dangerous waste that:
(a) Is exempt from regulation under WAC 173-303-071; or
(b) Is recycled under WAC 173-303-120 (2)(a), (3)(c)((, (e),))and (h), or (5); or
(c) Is managed in accordance with WAC 173-303-802(5) immediately upon generation only in on-site elementary neutralization units, wastewater treatment units, or totally enclosed treatment facilities as defined in WAC 173-303-040; or
(d) Is recycled, without prior storage or accumulation, only in an on-site process subject to regulation under WAC 173-303-120 (4)(a); or
(e) Is spent lead-acid batteries managed under the requirements of WAC 173-303-120 (3)(f) and 173-303-520; or
(f) Is universal waste managed under WAC 173-303-077 and 173-303-573; or
(g) Is a dangerous waste that is an unused commercial chemical product (listed in WAC 173-303-9903 or exhibits one or more characteristics or criteria listed in WAC 173-303-090 or 173-303-100) that is generated solely as a result of a laboratory clean-out conducted at an eligible academic entity pursuant to WAC 173-303-235(14). For purposes of this provision, the term eligible academic entity shall have the meaning as defined in WAC 173-303-235(1).
(h) (Reserved.)
(i) Is managed as part of an episodic event in compliance with the conditions of WAC 173-303-173.
(j) Is a dangerous waste pharmaceutical, as defined in WAC 173-303-555(1), that is managed in accordance with WAC 173-303-555 or is a dangerous waste pharmaceutical that is also a Drug Enforcement Administration controlled substance and managed under WAC 173-303-555(7). The total dangerous waste, including both dangerous waste pharmaceuticals and nonpharmaceutical dangerous waste, must be counted per WAC 173-303-170(10) for purposes of determining if a health care facility is subject to WAC 173-303-555.
(5) In determining the quantity of dangerous waste generated, a generator need not include:
(a) Dangerous waste when it is removed from on-site storage; or
(b) Spent materials that are generated, reclaimed, and subsequently reused on site, as long as such spent materials have been counted once (note: If after treatment or reclamation a residue is generated with a different waste code(s), that residue must be counted); or
(c) The container holding/containing the dangerous waste as described under WAC 173-303-160(1).
(6) Based on the generator category as determined under this section, the generator must meet the applicable independent requirements listed in WAC 173-303-170. A generator's category also determines which of the provisions of WAC 173-303-171, 173-303-172, 173-303-174 or 173-303-200 must be met to obtain an exemption from the storage facility permit, interim status, and operating requirements when accumulating dangerous waste.
(a) In a calendar month, if a small quantity generator generates more than the amounts specified in the definition of "small quantity generator" in WAC 173-303-040, the generator becomes subject to full requirements of a medium quantity generator or large quantity generator of this chapter, respectively, and cannot again be a small quantity generator until after all dangerous waste on site at the time they became fully regulated have been properly treated or disposed at a designated facility.
Example. If a person generates 4 pounds of an acute hazardous waste discarded chemical product (QEL 2.2 pounds) and 200 pounds of an ignitable waste (QEL 220 pounds), then both wastes are fully regulated, and the person is not a small quantity generator for either waste. "Fully regulated" in this example means the regulations applicable to a large quantity generator.
(b) In a calendar month if a medium quantity generator generates more than the amounts specified in the definition of "medium quantity generator" in WAC 173-303-040 the generator becomes subject to full requirements of a large quantity generator of this chapter, and cannot again be a medium quantity generator until after all dangerous waste on site at the time they became fully regulated have been properly treated or disposed at a designated facility.

AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-180Manifest.
A generator who transports, or offers for transport a dangerous waste for off-site treatment, storage, or disposal, or a treatment, storage, ((and))or disposal facility ((who))that offers for transport a rejected dangerous waste load, must follow all applicable procedures described in this section.
(1) Form and contents of dangerous waste manifests. 40 C.F.R. Part 262 Appendix - Uniform Hazardous Waste Manifest and Instructions (EPA Forms 8700-22 and 8700-22A and Their Instructions) is incorporated by reference. The manifest must be EPA Form 8700-22 and, if necessary, EPA Form 8700-22A. The manifest must be prepared in accordance with the instructions for these forms((, as described in the uniform manifest Appendix of 40 C.F.R. Part 262)).
(a) A generator must designate on the manifest one facility that is permitted to handle the waste described on the manifest.
(b) A generator may also designate on the manifest one alternate facility that is permitted to handle their waste in the event an emergency prevents delivery of the waste to a primary designated facility.
(c) If the transporter is unable to deliver the dangerous waste to the designated facility or the alternate facility, the generator must either designate another facility or instruct the transporter to return the waste.
(2) The manifest must consist of enough copies to provide the generator, each transporter, and the designated facility owner/operator with a copy for their records, and another copy to be returned to the generator.
(3) Manifest procedures.
(a) The generator must:
(i) Sign and date the manifest certification by hand;
(ii) Obtain the handwritten signature of the initial transporter and date of acceptance on the manifest; and
(iii) Retain one copy in accordance with WAC 173-303-210, Generator recordkeeping.
(b) The generator must give the remaining manifest copies to the transporter.
(c) For shipments of dangerous waste within the United States solely by water (bulk shipments only), the generator must send three copies of the manifest dated and signed in accordance with this section to the owner or operator of the designated facility or the last water (bulk shipment) transporter to handle the waste in the United States if exported by water. Copies of the manifest are not required for each transporter.
(d) For rail shipments of dangerous waste within the United States which originate at the site of generation, the generator must send at least three copies of the manifest dated and signed in accordance with this section to:
(i) The next nonrail transporter, if any; or
(ii) The designated facility if transported solely by rail; or
(iii) The last rail transporter to handle the waste in the United States if exported by rail.
(e) For shipments of federally regulated hazardous waste to a designated facility in an authorized state which has not yet obtained authorization to regulate that particular waste as hazardous, the generator must assure that the designated facility agrees to sign and return the manifest to the generator, and that any out-of-state transporter signs and forwards the manifest to the designated facility.
(f) For rejected shipments of dangerous waste or container residues contained in nonempty containers that are returned to the generator by the designated facility (following the procedures of WAC 173-303-370 (5)(f)), the generator must:
(i) Sign either:
(A) Item 20 of the new manifest if a new manifest is used for the returned shipment; or
(B) Item 18c of the original manifest if the original manifest is used for the returned shipment.
(ii) Provide the transporter a copy of the manifest;
(iii) Within thirty days of delivery of the rejected shipment or container residues contained in nonempty containers, send a copy of the manifest to the designated facility that returned the shipment to the generator; and
(iv) Retain at the generator's site a copy of each manifest for at least three years from the date of delivery.
(4) Special requirements for shipments to the Washington EHW facility at Hanford.
(a) All generators planning to ship dangerous waste to the EHW facility at Hanford must notify the facility in writing and by sending a copy of the prepared manifest prior to shipment.
(b) The generator must not ship any dangerous waste without prior approval from the EHW facility. The state operator may exempt classes of waste from the requirements of WAC 173-303-180 (4)(a) and (b) where small quantities or multiple shipments of a previously approved waste are involved, or there exists an emergency and potential threat to public health and safety.
(5) The requirements of this section and WAC 173-303-190(2) do not apply to the transport of dangerous wastes on a public or private right of way within or along the border of contiguous property under the control of the same person, even if such contiguous property is divided by a public or private right of way: Provided, That ecology has approved an alternative paper tracking system that serves the purpose of a manifest. Notwithstanding WAC 173-303-240(2), the generator or transporter must comply with the requirements for transporters set forth in WAC 173-303-270 and 173-303-145 in the event of a discharge of dangerous waste on a public or private right of way.
(6) Special instructions for state-only dangerous waste that designates only by the criteria under WAC 173-303-100 and is not regulated as a hazardous waste under 40 C.F.R. Part 261 or as a hazardous material under the 49 C.F.R. hazardous material regulations. For purposes of completing the uniform hazardous waste manifest, Item 9b, and Item 28 if continuation sheet 8700-22A is used, or to describe a state-only dangerous waste on a shipping paper, the shipping description must include the following in sequence with no additional information interspersed:
(a) Material Not Regulated by DOT;
(b) Washington State Dangerous Waste Only followed by the appropriate criteria designation of the waste that is either toxic, persistent, solid corrosive or a combination of these entered in parentheses;
(c) Shipping description examples: Material Not Regulated by DOT (Washington State Dangerous Waste Only, Toxic); Material Not Regulated by DOT (Washington State Dangerous Waste Only, Toxic, Persistent); Material Not Regulated by DOT (Washington State Dangerous Waste Only, Solid Corrosive).
(7) Manifest tracking numbers, manifest printing, and obtaining manifests.
(a) 40 C.F.R. 262.21 (a) through (f) and (h) through (m) is incorporated by reference. EPA requirements for printing manifests for use or distribution are included in this section.
(b) A generator may use manifests printed by any source so long as the source of the printed form has received approval from EPA to print the manifest under paragraphs (c) and (e) of 40 C.F.R. 262.21. A registered source may be a:
(i) State agency;
(ii) Commercial printer;
(iii) Dangerous waste generator, transporter or TSDF; or
(iv) Dangerous waste broker or other preparer who prepares or arranges shipments of dangerous waste for transportation.
(c) A generator must determine whether the generator state or the consignment state for a shipment regulates any additional wastes (beyond those regulated federally) as hazardous wastes under these states' authorized programs. Generators also must determine whether the consignment state or generator state requires the generator to submit any copies of the manifest to these states. In cases where the generator must supply copies to either the generator's state or the consignment state, the generator is responsible for supplying legible photocopies of the manifest to these states.
(8) Waste minimization certification. A generator who initiates a shipment of dangerous waste must certify to one of the following statements in Item 15 of the uniform hazardous waste manifest:
(a) "I am a large quantity generator. I have a program in place to reduce the volume and toxicity of waste generated to the degree I have determined to be economically practicable and I have selected the practicable method of treatment, storage, or disposal currently available to me which minimizes the present and future threat to human health and the environment"; or
(b) "I am a medium quantity generator. I have made a good faith effort to minimize my waste generation and select the best waste management method that is available to me and that I can afford." Note that a Washington state medium quantity generator regulated under WAC 173-303-172 is the type of generator referred to where the manifest states "(b) if I am a small quantity generator", due to the different term used by EPA.
(9) Use of electronic manifest. In lieu of using the manifest form specified in subsection (1) of this section, a person may prepare and use an electronic manifest, provided that the person:
(a) Complies with the requirements of 40 C.F.R. Part 3.10 for the reporting of electronic documents to EPA; and
(b) Complies with the requirements in subsections (10) and (11) of this section.
(10) Legal equivalence to paper manifests.
(a) Electronic manifests that are obtained, completed, and transmitted in accordance with subsection (9) of this section and used in accordance with this section are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in this section to obtain, complete, sign, provide, use or retain a manifest.
(i) Any requirement in this section to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of subsection (11) of this section.
(ii) Any requirement in this section to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the e-Manifest system.
(iii) Any requirement in this section for a generator to keep or retain a copy of each manifest is satisfied by retention of a signed electronic manifest in the generator's account on the national e-Manifest system, provided that such copies are readily available for viewing and production upon request.
(iv) A generator may not be held liable for the inability to produce an electronic manifest for inspection under this section if the generator can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the electronic manifest system for which the generator bears no responsibility.
(b) A generator may participate in the electronic manifest system either by accessing the electronic manifest system from its own electronic equipment, or by accessing the electronic manifest system from portable equipment brought to the generator's site by the transporter who accepts the dangerous waste shipment from the generator for off-site transportation.
(c)(i) Restriction on use of electronic manifests. A generator may prepare an electronic manifest for the tracking of dangerous waste shipments involving any dangerous waste only if it is known at the time the manifest is originated that all waste handlers named on the manifest participate in the electronic manifest system, except that:
(ii) A generator may sign by hand and retain a paper copy of the manifest signed by hand by the initial transporter, in lieu of executing the generator copy electronically, thereby enabling the transporter and subsequent waste handlers to execute the remainder of the manifest copies electronically.
(d) Requirement for one printed copy. To the extent the hazardous materials regulation on shipping papers for carriage by public highway requires shippers of hazardous material to supply a paper document for compliance with 49 C.F.R. Part 177.817, a generator originating an electronic manifest must also provide the initial transporter with one printed copy of the electronic manifest. In addition, the one printed copy of the electronic manifest must provide the information required in subsection (6) of this section for state-only dangerous waste that designates only by the criteria under WAC 173-303-100 and as state listed WPCB and WSC2.
(e) Special procedures when electronic manifest is unavailable. If a generator has prepared an electronic manifest for a dangerous waste shipment, but the electronic manifest system becomes unavailable for any reason prior to the time that the initial transporter has signed electronically to acknowledge the receipt of the dangerous waste from the generator, then the generator must obtain and complete a paper manifest (EPA form 8700-22) and if necessary, a continuation sheet (EPA form 8700-22A) in accordance with the manifest instructions and ((comply))use these paper forms from this point forward in compliance with subsections (1) through (8) of this section from this point forward.
(f) Special procedures for electronic signature methods undergoing tests. If a generator has prepared an electronic manifest for a dangerous waste shipment, and signs this manifest electronically using an electronic signature method which is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of this signature method, then the generator shall also sign with an ink signature the generator/offeror certification on the printed copy of the manifest provided under (d) of this subsection.
(g) Imposition of user fee. A generator who is a user of the electronic manifest may be assessed a user fee by EPA for the origination of each electronic manifest. EPA shall maintain and update from time-to-time the current schedule of electronic manifest user fees, which shall be determined based on current and projected system costs and level of use of the electronic manifest system. The current schedule of electronic manifest user fees will be published by EPA as an appendix to 40 C.F.R. Part 262.
(h) Post-receipt manifest data corrections. After facilities have certified to the receipt of dangerous waste by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person (e.g., waste handler) named on the manifest. Generators may participate electronically in the post-receipt data corrections process by following the process described in WAC 173-303-370 (10)(g), which applies to corrections made to either paper or electronic manifest records.
(11) Electronic manifest signatures. Electronic signature methods for the e-Manifest system shall:
(a) Be a legally valid and enforceable signature applicable under state, EPA and other federal requirements pertaining to electronic signatures; and
(b) Be a method that is designed and implemented in a manner that EPA considers to be as cost-effective and practical as possible for the users of the manifest.
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)

AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-201Preparedness, prevention, emergency procedures and contingency plans for large quantity generators.
(1) Applicability. The regulations of this section apply to those areas of a large quantity generator's facility where dangerous waste is generated or accumulated on site.
(2) A large quantity generator facility must be designed, constructed, maintained and operated to minimize the possibility of fire, explosion, or any unplanned sudden or nonsudden release of dangerous waste, hazardous substance or dangerous waste constituents to air, soil, or surface or groundwater which could threaten the public health or the environment. This section describes preparations and preventive measures which help avoid or mitigate such situations.
(3) Required equipment. All areas deemed applicable by subsection (1) of this section must be equipped with the following, unless it can be demonstrated to the department that none of the hazards posed by waste or hazardous substance handled at the facility could require a particular kind of equipment specified below. A large quantity generator may determine the most appropriate locations within its facility to locate equipment necessary to prepare for and respond to emergencies:
(a) An internal communications or alarm system capable of providing immediate emergency instruction (voice or signal) to facility personnel;
(b) A device, such as a telephone (immediately available at the scene of operations) or a hand-held, two-way radio, capable of summoning emergency assistance from local police departments, fire departments, or state or local emergency response teams;
(c) Portable fire extinguishers, fire control equipment (including special extinguishing equipment, such as those using foam, inert gas, or dry chemicals), spill control equipment, and decontamination equipment; and
(d) Water at adequate volume and pressure to supply water hose streams, foam producing equipment, automatic sprinklers, or water spray systems.
(4) Testing and maintenance of equipment. All facility communications or alarm systems, fire protection equipment, spill control equipment, and decontamination equipment, where required, must be tested and maintained as necessary to assure its proper operation in time of emergency.
(5) Access to communications or alarms. Personnel must have immediate access to the signaling devices described in the situations below:
(a) Whenever dangerous waste is being poured, mixed, spread, or otherwise handled, all personnel involved must have immediate access (e.g., direct or unimpeded access) to an internal alarm or emergency communication device, either directly or through visual or voice contact with another employee, unless such a device is not required in subsection (3) of this section;
(b) If there is ever just one employee on the premises while the facility is operating, they must have immediate access (e.g., direct or unimpeded access) to a device, such as a telephone (immediately available at the scene of operation) or a hand-held, two-way radio, capable of summoning external emergency assistance, unless such a device is not required in subsection (3) of this section.
(6) Aisle space. The generator must maintain aisle space to allow the unobstructed movement of personnel, fire protection equipment, spill control equipment, and decontamination equipment to any area of facility operation in an emergency, unless it can be demonstrated to the department that aisle space is not needed for any of these purposes.
(7) Arrangements with local authorities. The large quantity generator must attempt to make the following arrangements, as appropriate for the type of waste handled at its facility and the potential need for the services of these organizations, unless the hazards posed by wastes handled at the facility would not require these arrangements:
(a) Arrangements to familiarize police, fire departments, and emergency response teams with the layout of the facility, properties of dangerous waste handled at the facility and associated hazards, places where facility personnel would normally be working, entrances to and roads inside the facility, and possible evacuation routes;
(b) Arrangements to familiarize local hospitals with the properties of dangerous waste handled at the facility and the types of injuries or illnesses which could result from fires, explosions, or releases at the facility;
(c) Agreements with state emergency response teams, emergency response contractors, and equipment suppliers;
(d) Where more than one party might respond to an emergency, agreements designating primary emergency authority and agreements with any others to provide support to the primary emergency authority;

(f) A facility possessing twenty-four-hour response capabilities may seek a waiver from the authority having jurisdiction (AHJ) over the fire code with the facility's locality as far as needing to make arrangements with the local fire department as well as any other organization necessary to respond to an emergency, provided that the waiver is documented in the generator's operating record.
(8) Contingency plan purpose and implementation.
(a) The large quantity generator must have a contingency plan for the facility. The purpose of a contingency plan and emergency procedures is to lessen the potential impact on the public health and the environment due to any emergency event such as, but not limited to, a fire, natural disaster, explosion, or any unplanned sudden or nonsudden release of dangerous waste, hazardous substance or dangerous waste constituents to air, soil, surface water, or groundwater.
(b) A contingency plan must be developed to lessen the potential impacts of such emergency events, and the plan must be implemented immediately when such emergency events occur.
(9) Contents of a contingency plan.
(a) Each large quantity generator must have a contingency plan at their facility for use in emergencies or any sudden or nonsudden releases which threaten human health and the environment. If the generator has already prepared a spill prevention control and countermeasures (SPCC) plan in accordance with 40 C.F.R. Part 112, or some other emergency or contingency plan, they need only amend that plan to incorporate dangerous waste management provisions that are sufficient to comply with the requirements of this section. The large quantity generator may develop one contingency plan that meets all regulatory requirements. Ecology recommends that the plan be based on the National Response Team's Integrated Contingency Plan Guidance ("One Plan").
(b) The contingency plan must contain the following:
(i) A description of the actions which facility personnel must take to comply with subsections (8) through (14) of this section and WAC 173-303-145;
(ii) A description of the actions which will be taken in the event that a dangerous waste shipment, which is damaged or otherwise presents a hazard to the public health and the environment, arrives at the facility, and is not acceptable to the large quantity generator, but cannot be transported, pursuant to the requirements of WAC 173-303-370(6), manifest system, reasons for not accepting dangerous waste shipments;
(iii) A description of the arrangements agreed to by local police departments, fire departments, hospitals, contractors, and state and local emergency response teams to coordinate emergency services as required in subsection (7) of this section;

Where more than one person is listed, one must be named as primary emergency coordinator, and others must be listed in the order in which they will assume responsibility as alternates. In situations where the large quantity generator facility has an emergency coordinator continuously on duty because it operates twenty-four hours per day, every day of the year, the plan may list the staffed position (e.g., operations manager, shift coordinator, shift operations supervisor) as well as an emergency telephone number that can be guaranteed to be answered at all times;
(v) A list of all emergency equipment at the facility (such as fire extinguishing systems, spill control equipment, communications and alarm systems, and decontamination equipment), where this equipment is required. This list must be kept up to date. In addition, the plan must include the location and a physical description of each item on the list, and a brief outline of its capabilities; and
(vi) An evacuation plan for facility personnel where there is a possibility that evacuation could be necessary. This plan must describe the signal(s) to be used to begin evacuation, evacuation routes, and alternate evacuation routes (in cases where the primary routes could be blocked by releases of materials or fires).
(10) Copies of contingency plan. A copy of the contingency plan and all revisions to the plan must be:
(a) Maintained at the large quantity generator's facility; and
(b) Submitted by the large quantity generator to all local emergency responders (i.e., police departments, fire departments, hospitals, and state and local emergency response teams) that may be called upon to provide emergency services.
(11) Quick reference guide.
(a) A large quantity generator who first becomes subject to these provisions and any current large quantity generator who is amending its contingency plan must at that time submit a quick reference guide of the contingency plan to the local emergency responders identified in subsection (10) of this section.
(b) Contents of the quick reference guide. This quick reference guide must include the following elements:
(i) The types and names of dangerous waste in layman's terms and the associated hazards associated with each dangerous waste present at any one time (e.g., toxic paint waste, spent ignitable solvent, corrosive acid);
(ii) The estimated maximum amount of each dangerous waste that may be present at any one time;
(iii) The identification of any dangerous waste where exposure would require unique or special treatment by medical or hospital staff;
(iv) A map of the facility showing where dangerous wastes are generated, accumulated, recycled and treated and routes for accessing these wastes;
(v) A street map of the facility in relation to surrounding businesses, schools and residential areas to understand how best to get to the facility and also evacuate citizens and workers;
(vi) The locations of water supply (e.g., fire hydrant and its flow rate);
(vii) The identification of on-site notification systems (e.g., a fire alarm that rings off site, smoke alarms); and
(viii) The name of the emergency coordinator(s) and seven days/twenty-four-hours emergency telephone number(s) or, in the case of a facility where an emergency coordinator is continuously on duty, the emergency telephone number for the emergency coordinator.

(12) Amendments of a contingency plan. The large quantity generator must review and immediately amend the contingency plan, if necessary, whenever:
(a) Applicable regulations are revised;
(b) The plan fails in an emergency;
(c) The generator's facility changes (in its design, construction, operation, maintenance, or other circumstances) in a way that materially increases the potential for fires, explosions, or releases of dangerous waste or dangerous waste constituents, or in a way that changes the response necessary in an emergency;
(d) The list of emergency coordinators changes; or
(e) The list of emergency equipment changes.
(13) Emergency coordinator. At all times, there must be at least one employee either on the facility premises or on call (that is, available to respond to an emergency by reaching the facility within a short period of time) with the responsibility for coordinating all emergency response measures. This emergency coordinator must be thoroughly familiar with all aspects of the facility's contingency plan, required by subsection (9) of this section, all operations and activities at the facility, the location and properties of all wastes handled, the location of all records within the facility, and the facility layout. In addition, this person must have the authority to commit the resources needed to carry out the contingency plan and to implement the necessary emergency procedures outlined in subsection (14) of this section.
(14) Emergency procedures. The following procedures must be implemented in the event of an emergency:
(a) Whenever there is an imminent or actual emergency situation, the emergency coordinator (or designee when the emergency coordinator is on call) must immediately:
(i) Activate internal facility alarms or communication systems, where applicable, to notify all facility personnel; and
(ii) Notify appropriate state or local agencies with designated response roles if their help is needed.
(b) Whenever there is a release, fire, or explosion, the emergency coordinator must immediately identify the character, exact source, amount, and areal extent of any released materials.
(c) Concurrently, the emergency coordinator must assess possible hazards to human health and the environment (considering direct, indirect, immediate, and long-term effects) that may result from the release, fire, or explosion.
(d) If the emergency coordinator determines that the facility has had a release, fire, or explosion which could threaten human health or the environment, they must report their findings as follows:
(i) If their assessment indicates that evacuation of local areas may be advisable, they must immediately notify appropriate local authorities. They must be available to help appropriate officials decide whether local areas should be evacuated; and
(ii) They must immediately notify the department and either the government official designated as the on-scene coordinator, or the National Response Center (using their twenty-four-hour toll free number 1-800-424-8802).

(ii) The thirty-five and forty-five day time frames begin the date the waste was accepted by the initial transporter forwarding the dangerous waste shipment from the designated facility to the alternate facility.
Note:
The submission to the department need only be a handwritten or typed note on the manifest itself, or on an attached sheet of paper, stating that the return copy was not received.
(3) Additional reports. The ((director, as they))department, as it deems necessary under chapter 70.105 RCW, may require a generator to furnish additional reports (including, but not limited to, engineering reports, nonengineering reports, plans, and specifications) concerning the quantities and disposition of the generator's dangerous waste and the generator's compliance with this chapter.
AMENDATORY SECTION(Amending WSR 19-04-038, filed 1/28/19, effective 4/28/19)
WAC 173-303-250Dangerous waste acceptance, transport, and delivery.
(1)(a) A transporter may not accept dangerous waste from a generator unless the transporter is also provided with a manifest signed in accordance with WAC 173-303-180(3) (Manifest procedures) or is provided with an electronic manifest that is obtained, completed, and transmitted in accordance with WAC 173-303-180(9) and signed with a valid and enforceable electronic signature as described in WAC 173-303-180(11).
(b) Exports. For exports of dangerous waste subject to 40 C.F.R. 262 Subpart H (which is incorporated by reference at WAC 173-303-230(1)), a transporter may not accept such waste without a manifest signed by the generator in accordance with this section, as appropriate, and for exports occurring under the terms of a consent issued by EPA on or after December 31, 2016, a movement document that includes all information required by 40 C.F.R. Part 262.83(d).
(2) Before transporting a dangerous waste shipment, the transporter must sign and date the manifest, acknowledging acceptance of the dangerous waste. The transporter must return a signed copy to the generator before commencing transport.
(3) The transporter must insure that the manifest accompanies the dangerous waste shipment. In the case of exports occurring under the terms of a consent issued by EPA to the exporter on or after December 31, 2016, the transporter must ensure that a movement document that includes all information required by 40 C.F.R. Part 262.83(d) also accompanies the dangerous waste. In the case of imports occurring under the terms of a consent issued by EPA to the country of export or the importer on or after December 31, 2016, the transporter must ensure that a movement document that includes all information required by 40 C.F.R. Part 262.84(d) also accompanies the dangerous waste.
(4) A transporter who delivers a dangerous waste to another transporter, or to the designated facility must:
(a) Obtain the date of delivery and the handwritten signature of that transporter or designated facility owner/operator on the manifest;
(b) Retain one copy of the manifest in accordance with WAC 173-303-260, Transporter recordkeeping; and
(c) Give the remaining copies of the manifest to the accepting transporter or designated facility.
(5) Except as provided in subsection (6) of this section, the transporter must deliver the entire quantity of dangerous waste which they have accepted from a generator or a transporter to:
(a) The designated facility listed on the manifest; or
(b) The alternate designated facility, if the dangerous waste cannot be delivered to the designated facility because an emergency prevents delivery; or
(c) The next designated transporter; or
(d) The place outside the United States designated by the generator.
(6)(a) Emergency condition. If the dangerous waste cannot be delivered in accordance with subsection (5)(a), (b) and (d) of this section because of an emergency condition other than rejection of the waste by the designated facility, or alternate designated facility, then the transporter must contact the generator for further directions and must revise the manifest according to the generator's instructions.
(b) Transporters without generator authority. If the dangerous waste is not delivered to the next designated transporter in accordance with subsection (5)(c) of this section, and the current transporter is without contractual authorization from the generator to act as the generator's agent with respect to transporter additions or substitutions, then the current transporter must contact the generator for further instructions prior to making any revisions to the transporter designations on the manifest. The current transporter may thereafter make such revisions if:
(i) The dangerous waste is not delivered in accordance with subsection (5)(c) of this section because of an emergency condition; or
(ii) The current transporter proposes to change the transporter(s) designated on the manifest by the generator, or to add a new transporter during transportation, to respond to an emergency, or for purposes of transportation efficiency, convenience, or safety; and
(iii) The generator authorizes the revision.
(c) Transporters with generator authorization. If the dangerous waste is not delivered to the next designated transporter in accordance with subsection (5)(c) of this section, and the current transporter has authorization from the generator to act as the generator's agent, then the current transporter may change the transporters(s) designated on the manifest, or add a new transporter, during transportation without the generator's prior, explicit approval, provided that:
(i) The current transporter is authorized by a contractual provision that provides explicit agency authority for the transporter to make such transporter changes on behalf of the generator;
(ii) The transporter enters in Item 14 of each manifest for which such a change is made, the following statement of its agency authority: "Contract retained by generator confers agency authority on initial transporter to add or substitute additional transporters on generator's behalf"; and
(iii) The change in designated transporters is necessary to respond to an emergency, or for purposes of transportation efficiency, convenience, or safety.
(d) Generator liability. The grant by the generator of authority to a transporter to act as the agent of the generator with respect to changes to transporter designations under (c) of this subsection does not affect the generator's liability or responsibility for complying with any applicable requirement under this chapter, or grant any additional authority to the transporter to act on behalf of the generator.
(e) Rejected loads. If dangerous waste is rejected by the designated facility while the transporter is on the facility's premises, then the transporter must obtain the following:
(i) For a partial load rejection or for regulated quantities of container residues, a copy of the original manifest that includes the facility's date and signature, and the manifest tracking number of the new manifest that will accompany the shipment, and a description of the partial rejection or container residue in the discrepancy block of the original manifest. The transporter must retain a copy of this manifest in accordance with WAC 173-303-260, and give the remaining copies of the original manifest to the rejecting designated facility. If the transporter is forwarding the rejected part of the shipment or a regulated container residue to an alternate facility or returning it to the generator, the transporter must obtain a new manifest to accompany the shipment, and the new manifest must include all of the information required in WAC 173-303-370 (5)(e)(i) through (vi) or 173-303-370 (5)(f)(i) through (vi).
(ii) For a full load rejection that will be taken back by the transporter, a copy of the original manifest that includes the rejecting facility's signature and date attesting to the rejection, the description of the rejection in the discrepancy block of the manifest, and the name, address, phone number, and identification number for the alternate facility or generator to whom the shipment must be delivered. The transporter must retain a copy of the manifest in accordance with WAC 173-303-260, and give a copy of the manifest containing this information to the rejecting designated facility. If the original manifest is not used, then the transporter must obtain a new manifest for the shipment and comply with WAC 173-303-370 (5)(e)(i) through (vi).
(7) The requirements of subsections (3), (4), and (8) of this section do not apply to water (bulk shipment) transporters if:
(a) The dangerous waste is delivered by water (bulk shipment) to the designated facility; and
(b) A shipping paper containing all the information required on the manifest (excluding the EPA/state identification numbers, generator certification, and signatures) and, for exports or imports occurring under the terms of a consent issued by EPA on or after December 31, 2016, a movement document that includes all information required by 40 C.F.R. part 262.83(d) or 262.84(d) accompanies the dangerous waste; and
(c) The delivering transporter obtains the date of delivery and handwritten signature of the owner or operator of the designated facility on either the manifest or the shipping paper; and
(d) The person delivering the dangerous waste to the initial water (bulk shipment) transporter obtains the date of delivery and signature of the water (bulk shipment) transporter on the manifest and forwards it to the designated facility; and
(e) A copy of the shipping paper or manifest is retained by each water (bulk shipment) transporter in accordance with WAC 173-303-260(2).
(8) For shipments involving rail transportation, the requirements of subsections (3), (4), and (7) of this section do not apply and the following requirements do apply.
(a) When accepting dangerous waste from a nonrail transporter, the initial rail transporter must:
(i) Sign and date the manifest acknowledging acceptance of the dangerous waste;
(ii) Return a signed copy of the manifest to the nonrail transporter;
(iii) Forward at least three copies of the manifest to:
(A) The next nonrail transporter, if any; or
(B) The designated facility, if the shipment is delivered to that facility by rail; or
(C) The last rail transporter designated to handle the waste in the United States;
(iv) Retain one copy of the manifest and rail shipping paper in accordance with WAC 173-303-260(2).
(b) Rail transporters must ensure that a shipping paper containing all the information required on the manifest (excluding the EPA/state identification numbers, generator certification, and signatures) and, for exports or imports occurring under the terms of a consent issued by EPA on or after December 31, 2016, a movement document that includes all information required by 40 C.F.R. Part 262.83(d) or 262.84(d) accompanies the dangerous waste at all times. (Note: Intermediate rail transporters are not required to sign the manifest, movement document, or shipping paper.)
(c) When delivering dangerous waste to the designated facility, a rail transporter must:
(i) Obtain the date of delivery and handwritten signature of the owner or operator of the designated facility on the manifest or the shipping paper (if the manifest has not been received by the facility); and

(ii) For shipments initiated prior to the automated export system (AES) filing compliance date, when instructed by the exporter to do so, give a copy of the manifest to a U.S. Customs official at the point of departure from the United States.
(10) Use of electronic manifest.
(a) Legal equivalence to paper forms for participating transporters. Electronic manifests that are obtained, completed, and transmitted in accordance with WAC 173-303-180(9) and used in accordance with this section are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in this section to obtain, complete, sign, provide, give, use or retain a manifest.
(i) Any requirement in this section to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of WAC 173-303-180(11).
(ii) Any requirement in this section to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the e-Manifest system.
(iii) Any requirement in this section for a manifest to accompany a dangerous waste shipment is satisfied when a copy of an electronic manifest is accessible during transportation and forwarded to the person or persons who are scheduled to receive delivery of the waste shipment, except that to the extent that the hazardous materials regulation on shipping papers for carriage by public highway requires transporters of hazardous materials to carry a paper document to comply with 40 C.F.R. Part 177.817, a dangerous waste transporter must carry one printed copy of the electronic manifest on the transport vehicle. In addition, the one printed copy of the electronic manifest must provide the information required in WAC 173-303-180(6) for state-only dangerous waste that designates only by the criteria under WAC 173-303-100.
(iv) Any requirement in this section for a transporter to keep or retain a copy of each manifest is satisfied by retention of a signed electronic manifest in the transporter's account on the national e-Manifest system, provided that such copies are readily available for viewing and production upon request.
(v) A transporter may not be held liable for the inability to produce an electronic manifest for inspection under this section if the transporter can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the EPA's electronic manifest system for which the transporter bears no responsibility.
(b) A transporter may participate in the electronic manifest system either by accessing the electronic manifest system from the transporter's own electronic equipment, or by accessing the electronic manifest system from the equipment provided by a participating generator, by another transporter, or by a designated facility.
(c) Special procedures when electronic manifest is not available. If after a manifest has been originated electronically and signed electronically by the initial transporter, and the electronic manifest system should become unavailable for any reason, then:
(i) The transporter in possession of the dangerous waste when the electronic manifest becomes unavailable shall reproduce sufficient copies of the printed manifest that is carried on the transport vehicle pursuant to (a)(iii) of this subsection, or obtain and complete another paper manifest for this purpose. The transporter shall reproduce sufficient copies to provide the transporter and all subsequent waste handlers with a copy for their files, plus two additional copies that will be delivered to the designated facility with the dangerous waste.
(ii) On each printed copy, the transporter shall include a notation in the special handling and additional description space (Item 14) that the paper manifest is a replacement manifest for the manifest originated in the electronic manifest system, shall include (if not preprinted on the replacement manifest) the manifest tracking number of the electronic manifest that is replaced by the paper manifest, and shall also include a brief explanation why the electronic manifest was not available for completing the tracking of the shipment electronically.
(iii) A transporter signing a replacement manifest to acknowledge receipt of the dangerous waste must ensure that each paper copy is individually signed and that a legible handwritten ink signature appears on each copy.
(iv) From the point at which the electronic manifest is no longer available for tracking the waste shipment, the paper replacement manifest copies shall be carried, signed, retained as records, and given to a subsequent transporter or to the designated facility, following the instructions, procedures, and requirements that apply to the use of all other paper manifests.
(d) Special procedures for electronic signature methods undergoing tests. If a transporter using an electronic manifest signs this manifest electronically using an electronic signature method which is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of this signature method, then the transporter shall sign the electronic manifest electronically and also sign with an ink signature the transporter acknowledgment of receipt of materials on the printed copy of the manifest that is carried on the vehicle in accordance with (a)(iii) of this subsection. This printed copy bearing the generator's and transporter's ink signatures shall also be presented by the transporter to the designated facility to sign in ink to indicate the receipt of the waste materials or to indicate discrepancies. After the owner/operator of the designated facility has signed this printed manifest copy with its ink signature, the printed manifest copy shall be delivered to the designated facility with the waste materials.
(e) Imposition of user fee. A transporter who is a user of the electronic manifest may be assessed a user fee by EPA for the origination or processing of each electronic manifest. EPA shall maintain and update from time-to-time the current schedule of electronic manifest user fees, which shall be determined based on current and projected system costs and level of use of the electronic manifest system. The current schedule of electronic manifest user fees will be published as an appendix to 40 C.F.R. Part 262, by EPA.
(f) Post-receipt manifest data corrections. After facilities have certified to the receipt of dangerous waste by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person (e.g., waste handler) named on the manifest. Transporters may participate electronically in the post-receipt data corrections process by following the process described in WAC 173-303-370 (10)(g), which applies to corrections made to either paper or electronic manifest records.

(e) Retain at the facility a copy of each manifest and shipping paper ((and manifest))(if signed in lieu of the manifest at the time of delivery) for at least three years from the date of delivery.
(5) Manifest discrepancies.
(a) Manifest discrepancies are:
(i) Significant differences (as defined in (b) of this subsection) between the quantity or type of dangerous waste designated on the manifest or shipping paper, and the quantity and type of dangerous waste a facility actually receives;
(ii) Rejected wastes, which may be a full or partial shipment of dangerous waste that the TSDF cannot accept; or
(iii) Container residues, which are residues that exceed the quantity limits for "empty" containers set forth in WAC 173-303-160(2).
(b) Significant differences in quantity are: For bulk waste, variations greater than ten percent in weight (for example, tanker trucks, railroad tank cars, etc.); for batch waste, any variations in piece count, such as a discrepancy of one drum in a truckload. Significant differences in type are obvious differences which can be discovered by inspection or waste analysis such as waste solvent substituted for waste acid, or toxic constituents not reported on the manifest or shipping paper.
(c) Upon discovering a significant difference in quantity or type, the owner or operator must attempt to reconcile the discrepancy with the waste generator or transporter. If the discrepancy is not resolved within fifteen days after receiving the waste, the owner or operator must immediately submit to the department a letter describing the discrepancy and attempts to reconcile it, and a copy of the manifest or shipping paper at issue.
(d)(i) Upon rejecting waste or identifying a container residue that exceeds the quantity limits for "empty" containers set forth in WAC 173-303-160(2), the facility must consult with the generator prior to forwarding the waste to another facility that can manage the waste. If it is impossible to locate an alternative facility that can receive the waste, the facility may return the rejected waste or residue to the generator. The facility must send the waste to the alternative facility or to the generator within sixty days of the rejection or the container residue identification.
(ii) While the facility is making arrangements for forwarding rejected wastes or residues to another facility under this section, it must ensure that either the delivering transporter retains custody of the waste, or the facility must provide for secure, temporary custody of the waste, pending delivery of the waste to the first transporter designated on the manifest prepared under (e) or (f) of this subsection.
(e) Except as provided in (e)(vii) of this subsection, for full or partial load rejections and residues that are to be sent off-site to an alternate facility, the facility is required to prepare a new manifest in accordance with WAC 173-303-180 and the following instructions:
(i) Write the generator's EPA/state ID# in Item 1 of the new manifest. Write the generator's name and mailing address in Item 5 of the new manifest. If the mailing address is different from the generator's site address, then write the generator's site address in the designated space for Item 5.
(ii) Write the name of the alternate designated facility and the facility's EPA/state ID# in the designated facility block (Item 8) of the new manifest.
(iii) Copy the manifest tracking number found in Item 4 of the old manifest to the special handling and additional information block of the new manifest, and indicate that the shipment is a residue or rejected waste from the previous shipment.
(iv) Copy the manifest tracking number found in Item 4 of the new manifest to the manifest reference number line in the discrepancy block of the old manifest (Item 18a).
(v) Write the DOT description for the rejected load or the residue in Item 9 (U.S. DOT Description) of the new manifest and write the container types, quantity, and volume(s) of waste.
(vi) Sign the generator's/offeror's certification to certify, as the offeror of the shipment, that the waste has been properly packaged, marked and labeled and is in proper condition for transportation and mail a signed copy of the manifest to the generator identified in Item 5 of the new manifest.
(vii) For full load rejections that are made while the transporter remains present at the facility, the facility may forward the rejected shipment to the alternate facility by completing Item 18b of the original manifest and supplying the information on the next destination facility in the alternate facility space. The facility must retain a copy of this manifest for its records, and then give the remaining copies of the manifest to the transporter to accompany the shipment. If the original manifest is not used, then the facility must use a new manifest and comply with (e)(i), (ii), (iii), (iv), (v), and (vi) of this subsection.
(f) Except as provided in (f)(vii) of this subsection, for rejected wastes and residues that must be sent back to the generator, the facility is required to prepare a new manifest in accordance with WAC 173-303-180 and the following instructions:
(i) Write the facility's EPA/state ID# in Item 1 of the new manifest. Write the facility's name and mailing address in Item 5 of the new manifest. If the mailing address is different from the facility's site address, then write the facility's site address in the designated space for Item 5 of the new manifest.
(ii) Write the name of the initial generator and the generator's EPA/state ID# in the designated facility block (Item 8) of the new manifest.
(iii) Copy the manifest tracking number found in Item 4 of the old manifest to the special handling and additional information block of the new manifest, and indicate that the shipment is a residue or rejected waste from the previous shipment.
(iv) Copy the manifest tracking number found in Item 4 of the new manifest to the manifest reference number line in the discrepancy block of the old manifest (Item 18a).
(v) Write the DOT description for the rejected load or the residue in Item 9 (U.S. DOT Description) of the new manifest and write the container types, quantity, and volume(s) of waste.
(vi) Sign the generator's/offeror's certification to certify, as offeror of the shipment, that the waste has been properly packaged, marked and labeled and is in proper condition for transportation.
(vii) For full load rejections that are made while the transporter remains at the facility, the facility may return the shipment to the generator with the original manifest by completing Item 18a and 18b of the manifest and supplying the generator's information in the alternate facility space. The facility must retain a copy for its records and then give the remaining copies of the manifest to the transporter to accompany the shipment. If the original manifest is not used, then the facility must use a new manifest and comply with (f)(i), (ii), (iii), (iv), (v), (vi), and (viii) of this subsection.
(viii) For full or partial load rejections and container residues contained in nonempty containers that are returned to the generator, the facility must also comply with the exception reporting requirements in WAC 173-303-220(2).
(g) If a facility rejects a waste or identifies a container residue that exceeds the quantity limits for "empty" containers set forth in WAC 173-303-160(2) after it has signed, dated, and returned a copy of the manifest to the delivering transporter or to the generator, the facility must amend its copy of the manifest to indicate the rejected wastes or residues in the discrepancy space of the amended manifest. The facility must also copy the manifest tracking number from Item 4 of the new manifest to the discrepancy space of the amended manifest, and must re-sign and date the manifest to certify to the information as amended. The facility must retain the amended manifest for at least three years from the date of amendment, and must within thirty days, send a copy of the amended manifest to the transporter and generator that received copies prior to their being amended.
(6) Reasons for not accepting dangerous waste shipments. The owner or operator may decide that a dangerous shipment should not be accepted by their facility.
(a) The following are acceptable reasons for denying receipt of a dangerous waste shipment:
(i) The facility is not capable of properly managing the type(s) of dangerous waste in the shipment;
(ii) There is a significant discrepancy (as described in subsection (5) of this section) between the shipment and the wastes listed on the manifest or shipping paper; or
(iii) The shipment has arrived in a condition which the owner or operator believes would present an unreasonable hazard to facility operations, or to facility personnel handling the dangerous waste(s) (including, but not limited to, leaking or damaged containers, and improperly labeled containers).
(b) The owner or operator may send the shipment on to the alternate facility designated on the manifest or shipping paper, or contact the generator to identify another facility capable of handling the waste and provide for its delivery to that other facility, unless, the containers are damaged to such an extent, or the dangerous waste is in such a condition as to present a hazard to the public health or the environment in the process of further transportation.
(c) If the dangerous waste shipment cannot leave the facility for the reasons described in (b) of this subsection, then the owner or operator must take those actions described in the contingency plan, WAC 173-303-350 (3)(b).
(7) Within three working days of the receipt of a shipment subject to 40 C.F.R. Part 262, Subpart H (which is incorporated by reference at WAC 173-303-230(1)), the owner or operator of the facility must provide a copy of the movement document bearing all required signatures to the foreign exporter; to the competent authorities of the countries of export and transit that control the shipment as an export and transit of dangerous waste respectively; and on or after the electronic import-export reporting compliance date, to EPA electronically using EPA's Waste Import Export Tracking System (WIETS), or its successor system. The original copy of the movement document must be maintained at the facility for at least three years from the date of signature. The owner or operator of a facility may satisfy this recordkeeping requirement by retaining electronically submitted documents in the facility's account on EPA's WIETS, or its successor system, provided that copies are readily available for viewing and production if requested by any EPA or authorized state inspector. No owner or operator of a facility may be held liable for the inability to produce the documents for inspection under this section if the owner or operator of a facility can demonstrate that the inability to produce the document is due exclusively to technical difficulty with EPA's WIETS, or its successor system, for which the owner or operator of a facility bears no responsibility.
(8) A facility must determine whether the consignment state for a shipment regulates any additional wastes (beyond those regulated federally) as hazardous wastes under its state hazardous waste program. Facilities must also determine whether the consignment state or generator state requires the facility to submit any copies of the manifest to these states.
(9) Whenever a shipment of dangerous waste is initiated from a facility, the owner or operator of that facility must comply with the requirements of this chapter. The provisions of WAC 173-303-172, 173-303-174, and 173-303-200 through 173-303-201 of this chapter are applicable to the on-site accumulation of dangerous waste by generators. Therefore, the provisions of WAC 173-303-170, 173-303-172, 173-303-174, and 173-303-200 through 173-303-201 of this chapter only apply to owners or operators who are shipping dangerous waste which they generated at that facility or operating as a large quantity generator consolidating dangerous waste from small quantity generators under WAC 173-303-200(15).
(10) Use of electronic manifest.
(a) Legal equivalence to paper manifests. Electronic manifests that are obtained, completed, and transmitted in accordance with WAC 173-303-180(9) and used in accordance with this section in lieu of the paper manifest form are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in this section to obtain, complete, sign, provide, use or retain a manifest.
(i) Any requirement in this section for the owner or operator of a facility to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of WAC 173-303-180(11).
(ii) Any requirement in this section to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the e-Manifest system.
(iii) Any requirement in this section for a manifest to accompany a dangerous waste shipment is satisfied when a copy of an electronic manifest is accessible during transportation and forwarded to the person or persons who are scheduled to receive delivery of the dangerous waste shipment.
(iv) Any requirement in this section for an owner or operator of a facility to keep or retain a copy of each manifest is satisfied by retention of the facility's electronic manifest copies in its account on the national e-Manifest system, provided that such copies are readily available for viewing and production upon request.
(v) An owner or operator of a facility may not be held liable for the inability to produce an electronic manifest for inspection under this section if the owner or operator can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the EPA's electronic manifest system for which the owner or operator bears no responsibility.
(b) An owner or operator may participate in the electronic manifest system either by accessing the electronic manifest system from the owner's or operator's electronic equipment, or by accessing the electronic manifest system from portable equipment brought to the owner's or operator's site by the transporter who delivers the waste shipment to the facility.
(c) Special procedures applicable to replacement manifests. If a facility receives dangerous waste that is accompanied by a paper replacement manifest for a manifest that was originated electronically, the following procedures apply to the delivery of the dangerous waste by the final transporter:
(i) Upon delivery of the dangerous waste to the designated facility, the owner or operator must sign and date each copy of the paper replacement manifest by hand in Item 20 (Designated Facility Certification or Receipt) and note any discrepancies in Item 18 (Discrepancy Indication Space) of the replacement manifest;
(ii) The owner or operator of the facility must give back to the final transporter one copy of the paper replacement manifest;
(iii) Within thirty days of delivery of the dangerous waste to the designated facility, the owner or operator of the facility must send one signed and dated copy of the paper replacement manifest to the generator, and send an additional signed and dated copy of the paper replacement manifest to the EPA e-Manifest system; and
(iv) The owner or operator of the facility must retain at the facility one copy of the paper replacement manifest for at least five years from the date of delivery.
(d) Special procedures for electronic signature methods undergoing tests. If an owner or operator using an electronic manifest signs this manifest electronically using an electronic signature method which is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of this signature method, then the owner or operator shall also sign with an ink signature the facility's certification of receipt or discrepancies on the printed copy of the manifest provided by the transporter. Upon executing its ink signature on this printed copy, the owner or operator shall retain this original copy for at least five years from the date of delivery of the waste.
(e) Imposition of user fee. ((An owner or operator who is a user of the electronic manifest may be assessed a user fee by EPA for the origination and processing of each electronic manifest. An owner or operator may also be assessed a user fee by EPA for the collection and processing of paper manifest copies that owners or operators must submit to the electronic manifest system operator under subsection (2)(e) of this section. EPA shall maintain and update from time-to-time the current schedule of electronic manifest user fees, which shall be determined based on current and projected system costs and level of use of the electronic manifest system. The current schedule of electronic manifest user fees will be published as an appendix to 40 C.F.R. Part 262, by EPA.))
(i) As prescribed in 40 C.F.R. Part 264.1311, and determined in Part 264.1312, an owner or operator who is a user of the electronic manifest system shall be assessed a user fee by EPA for the submission and processing of each electronic and paper manifest. EPA shall update the schedule of user fees and publish them to the user community, as provided in 40 C.F.R. Part 264.1313.
(ii) An owner or operator subject to user fees under this section shall make user fee payments in accordance with the requirements of 40 C.F.R. Part 264.1314, subject to the informal fee dispute resolution process of 40 C.F.R. Part 264.1316, and subject to the sanctions for delinquent payments under 40 C.F.R. Part 264.1315.
(f) Electronic manifest signatures. Electronic manifest signatures shall meet the criteria described in WAC 173-303-180(11).
(g) Post-receipt manifest data corrections. After facilities have certified to the receipt of dangerous wastes by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person (e.g., waste handler) shown on the manifest.
(i) Interested persons must make all corrections to manifest data by electronic submission, either by directly entering corrected data to the web based service provided in e-Manifest for such corrections, or by an upload of a data file containing data corrections relating to one or more previously submitted manifests.
(ii) Each correction submission must include the following information:
(A) The manifest tracking number and date of receipt by the facility of the original manifest(s) for which data are being corrected;
(B) The item number(s) of the original manifest that is the subject of the submitted correction(s); and
(C) For each item number with corrected data, the data previously entered and the corresponding data as corrected by the correction submission.
(iii) Each correction submission shall include a statement that the person submitting the corrections certifies that to the best of his or her knowledge or belief, the corrections that are included in the submission will cause the information reported about the previously received dangerous wastes to be true, accurate, and complete:
(A) The certification statement must be executed with a valid electronic signature; and
(B) A batch upload of data corrections may be submitted under one certification statement.
(iv) Upon receipt by the system of any correction submission, other interested persons shown on the manifest will be provided electronic notice of the submitter's corrections.
(v) Other interested persons shown on the manifest may respond to the submitter's corrections with comments to the submitter, or by submitting another correction to the system certified by the respondent as specified in (e)(iii) of this subsection, and with notice of the corrections to other interested persons shown on the manifest.

(b) To be successful, the petitioner must demonstrate to the satisfaction of the department that regulation under the universal waste regulations of this section is: Appropriate for the waste or category of waste; will improve management practices for the waste or category of waste; and will improve implementation of the dangerous waste program. The petition must include the information required by WAC 173-303-910 (1)(b). The petition should also address as many of the factors listed in subsection (40) of this section as are appropriate for the waste or waste category addressed in the petition.
(c) The department will evaluate petitions using the factors listed in subsection (40) of this section. The department will grant or deny a petition using the factors listed in subsection (40) of this section. The decision will be based on the weight of evidence showing that regulation under this section is appropriate for the waste or category of waste, will improve management practices for the waste or category of waste, and will improve implementation of the dangerous waste program.
(d) Dangerous waste pharmaceuticals are regulated under WAC 173-303-555 and may not be added as a category of dangerous waste for the management under this section.
(40) Factors for petitions to include other wastes under this section.
(a) The waste or category of waste, as generated by a wide variety of generators, is listed in WAC 173-303-081 or 173-303-082, or (if not listed) a proportion of the waste stream exhibits one or more characteristics or criteria of dangerous waste identified in WAC 173-303-090 or 173-303-100. (When a characteristic waste is added to the universal waste regulations of this section by using a generic name to identify the waste category (for example, batteries), the definition of universal waste in WAC 173-303-040 will be amended to include only the dangerous waste portion of the waste category (for example, dangerous waste batteries).) Thus, only the portion of the waste stream that does exhibit one or more characteristics or criteria (that is, is dangerous waste) is subject to the universal waste regulations of this section;
(b) The waste or category of waste is not exclusive to a specific industry or group of industries, is commonly generated by a wide variety of types of establishments (including, for example, households, retail and commercial businesses, office complexes, conditionally exempt small quantity generators, small businesses, government organizations, as well as large industrial facilities);
(c) The waste or category of waste is generated by a large number of generators (for example, more than 1,000 nationally) and is frequently generated in relatively small quantities by each generator;
(d) Systems to be used for collecting the waste or category of waste (including packaging, marking, and labeling practices) would ensure close stewardship of the waste;
(e) The risk posed by the waste or category of waste during accumulation and transport is relatively low compared to other dangerous wastes, and specific management standards proposed or referenced by the petitioner (for example, waste management requirements appropriate to be added to subsections (9), (20), and (30) of this section; and/or applicable Department of Transportation requirements) would be protective of human health and the environment during accumulation and transport;
(f) Regulation of the waste or category of waste under this section will increase the likelihood that the waste will be diverted from nondangerous waste management systems (for example, the municipal waste stream, nondangerous industrial or commercial waste stream, municipal sewer or stormwater systems) to recycling, treatment, or disposal in compliance with the Hazardous Waste Management Act chapter 70.105 RCW, this chapter, and RCRA Subtitle C.
(g) Regulation of the waste or category of waste under this section will improve implementation of and compliance with the dangerous waste regulatory program; and/or
(h) Such other factors as may be appropriate.
(41) Applicability - Household and conditionally exempt small quantity generator waste.
(a) Persons managing the wastes listed below may, at their option, manage them under the requirements of this section:
(i) Household wastes that are exempt under WAC 173-303-071 (3)(c) and are also of the same type as the universal wastes defined at WAC 173-303-040; and/or
(ii) Small quantity generator wastes that are conditionally exempt under WAC 173-303-171 and are also of the same type as the universal wastes defined at WAC 173-303-040.
(b) Persons who commingle the wastes described in (a)(i) and (ii) of this subsection together with universal waste regulated under this section must manage the commingled waste under the requirements of this section.

WAC 173-303-630Use and management of containers.
(1) Applicability. The regulations in this section apply to owners and operators of all dangerous waste facilities that store dangerous waste in containers.
(2) Condition of containers. If a container holding dangerous waste is not in good condition (e.g., severe corroding or rusting or flaking or scaling, and/or apparent structural defects) or if it begins to leak, the owner or operator must transfer the dangerous waste from the container to a container that is in good condition or manage the waste in some other way that complies with the requirements of chapter 173-303 WAC. In addition, the owner or operator must address leaks and spills in accordance with the applicable provisions of WAC 173-303-145 and 173-303-360.
(3) Identification of containers. The owner or operator storing dangerous waste in containers must do the following:
(a) Clearly label or mark containers with the words "Dangerous Waste" or "Hazardous Waste." Except for containers one gallon (or four liters) and under, the lettering must be legible from a distance of twenty-five feet or the lettering size is a minimum of one-half inch in height.
(b) Clearly label or mark containers with an indication of the hazards of the contents (examples include, but are not limited to, the applicable dangerous waste characteristic(s) and criteria of ignitable, corrosive, reactive and toxic and the applicable hazard(s) identified for listed dangerous wastes). The label or marking must be:
(i) Legible and/or recognizable from a distance of twenty-five feet or the lettering size is a minimum of one-half inch in height; and
(ii) Include descriptive word(s) and/or pictogram(s) that identifies the hazards associated with the contents of the containers for employees, emergency response personnel, waste handlers, and the public; for containers one gallon (or four liters) and under the label, marking or lettering can be appropriate for the size of the container.
(c) Affix labels upon transfer of dangerous wastes from one container to another. The owner or operator must destroy or otherwise remove labels from the emptied container, unless the container will continue to be used for storing dangerous waste at the facility.
(d) Ensure that labels are not obscured, removed, or otherwise unreadable in the course of inspection required under WAC 173-303-320.
(4) Compatibility of waste with containers. The owner or operator must use a container made of or lined with materials which will not react with, and are otherwise compatible with, the dangerous waste to be stored, so that the ability of the container to contain the waste is not impaired.
(5) Management of containers.
(a) A container holding dangerous waste must always be closed, except when it is necessary to add or remove waste.
(b) A container holding dangerous waste must not be opened, handled, or stored in a manner which may rupture the container or cause it to leak.
(c) A minimum thirty-inch aisle space separation is required between rows of containers. A row of containers must be no more than two wide and allow for unobstructed inspection of each container.
(6) Inspections. The owner or operator must conduct "weekly inspections" (as defined in WAC 173-303-040), of areas where containers are stored, looking for leaking containers and for deterioration of containers and the containment system caused by corrosion, deterioration, or other factors. The owner or operator must keep a written or electronic inspection log including at least the date and time of the inspection, the printed name and the handwritten or electronic signature of the inspector, a notation of the observations made and the date and nature of any repairs or remedial actions taken. The log must be kept at the facility for at least five years from the date of inspection.
(7) Containment.
(a) Container storage areas must have a containment system that is capable of collecting and holding spills and leaks. In addition to the necessary leak containment capacity, uncovered storage areas must be capable of holding the additional volume that would result from the precipitation of a maximum twenty-five year storm of twenty-four hours duration. The containment system must:
(i) Have a base underlying the containers which is free of cracks or gaps and is sufficiently impervious to contain leaks, spills, and accumulated rainfall until the collected material is detected and removed. The base must be sloped or the containment system must be otherwise designed and operated to drain and remove liquids resulting from leaks, spills, or precipitation, unless the containers are elevated or are otherwise protected from contact with accumulated liquids;
(ii) Be designed for positive drainage control (such as a locked drainage valve) to prevent release of contaminated liquids and so that uncontaminated precipitation can be drained promptly for convenience of operation. Spilled or leaked waste and accumulated precipitation must be removed from the containment system in as timely a manner as is necessary to prevent overflow; and
(iii) Have sufficient capacity to contain ten percent of the volume of all containers or the volume of the largest container, whichever is greater. Only containers holding free liquids, or holding wastes designated as F020, F021, F022, F023, F026, or F027 need to be considered in this determination.
(b) Run-on into the containment system must be prevented, unless the department waives this requirement in the permit after determining that the collection system has sufficient excess capacity in addition to that required in (a)(iii) of this subsection to accommodate any run-on which might enter the system.
(c) Storage areas that store containers holding only wastes that do not contain free liquids, do not exhibit either the characteristic of ignitability or reactivity as described in WAC 173-303-090 (5) or (7), and are not designated as F020, F021, F022, F023, F026, or F027, need not have a containment system as described in this subsection: Provided, That:
(i) The storage area is sloped or is otherwise designed and operated to drain and remove liquid resulting from precipitation; or
(ii) The containers are elevated or are otherwise protected from contact with accumulated liquids.
(d) The department may require owners and operators to protect their containers from the elements by means of a building or other protective covering if the department determines that such protection is necessary to prevent a release of waste or waste constituents due to the nature of the waste or design of the container. The building or other protective covering must allow adequate inspection under subsection (6) of this section.
(8) Special requirements for ignitable or reactive waste.
(a) Containers holding reactive waste exhibiting a characteristic specified in WAC 173-303-090 (7)(a)(vi), (vii) or (viii) must be stored in a manner equivalent to the separation distances for storage of explosives in the International Fire Code, 2015 edition, or the version adopted by the local fire district.
(b) The owner or operator must design, operate, and maintain ignitable waste and reactive waste (other than a reactive waste which must meet (a) of this subsection) container storage in a manner equivalent with the International Fire Code. Where no specific standard or requirements are specified in the International Fire Code, or in existing state or local fire codes, applicable sections of the NFPA 30 "Flammable and Combustible Liquids Code," must be used. The owner/operator must also comply with the requirements of WAC 173-303-395 (1)(d).
(9) Special requirements for incompatible wastes.
(a) Incompatible wastes, or incompatible wastes and materials must not be placed in the same container, unless WAC 173-303-395 (1)(b) is complied with.
(b) Dangerous waste must not be placed in an unwashed container that previously held an incompatible waste or material.
(c) A storage container holding a dangerous waste that is incompatible with any waste or other materials stored nearby in other containers, piles, open tanks, or surface impoundments must be separated from the other materials or protected from them by means of a dike, berm, wall, or other device. Containment systems for incompatible wastes must be separate.
(10) Closure. At closure, all dangerous waste and dangerous waste residues must be removed from the containment system. Remaining containers, liners, bases, and soil containing or contaminated with dangerous waste or dangerous waste residues must be decontaminated or removed.
(11) Air emission standards. The owner or operator must manage all hazardous waste placed in a container in accordance with the applicable requirements of 40 C.F.R. Part 264, Subparts AA, BB, and CC, which are incorporated by reference at WAC 173-303-690 through 173-303-692.

The log must be kept at the facility for at least five years from the date of inspection.
(7) Response to leaks or spills and disposition of leaking or unfit-for-use tank systems.
A tank system or secondary containment system from which there has been a leak or spill, or which is unfit for use, must be removed from service immediately, and the owner or operator must satisfy the following requirements:
(a) Cessation of use; prevent flow or addition of wastes. The owner or operator must immediately stop the flow of dangerous waste into the tank system or secondary containment system and inspect the system to determine the cause of the release.
(b) Removal of waste from tank system or secondary containment system.
(i) If the release was from the tank system, the owner/operator must, within twenty-four hours after detection of the leak or, if the owner/operator demonstrates that it is not possible, at the earliest practicable time, remove as much of the waste as is necessary to prevent further release of dangerous waste to the environment and to allow inspection and repair of the tank system to be performed.
(ii) If the material released was to a secondary containment system, all released materials must be removed within twenty-four hours or in as timely a manner as is possible to prevent harm to human health and the environment.
(c) Containment of visible releases to the environment. The owner/operator must immediately conduct a visual inspection of the release and, based upon that inspection:
(i) Prevent further migration of the leak or spill to soils or surface water; and
(ii) Remove, and properly dispose of, any visible contamination of the soil or surface water.
(d) Notifications, reports.
(i) Any release to the environment must be reported to the department and other authorities immediately in accordance with WAC 173-303-145. Any release above the "reportable quantity" must also be reported to the National Response Center pursuant to 40 C.F.R. Part 302.

(A) Likely route of migration of the release;
(B) Characteristics of the surrounding soil (soil composition, geology, hydrogeology, climate);
(C) Results of any monitoring or sampling conducted in connection with the release (if available). If sampling or monitoring data relating to the release are not available within thirty days, these data must be submitted to the department as soon as they become available;
(D) Proximity to downgradient drinking water, surface water, and populated areas; and
(E) Description of response actions taken or planned.
(F) In the event of an emergency, additional information as required by WAC 173-303-360.
(e) Provision of secondary containment, repair, or closure.
(i) Unless the owner/operator satisfies the requirements of (e)(ii) through (iv) of this subsection, the tank system must be closed in accordance with subsection (8) of this section.
(ii) If the cause of the release was a spill that has not damaged the integrity of the system, the owner/operator may return the system to service as soon as the released waste is removed and repairs, if necessary, are made.
(iii) If the cause of the release was a leak from the primary tank system into the secondary containment system, the system must be repaired prior to returning the tank system to service.
(iv) If the source of the release was a leak to the environment from a component of a tank system without secondary containment, the owner/operator must provide the component of the system from which the leak occurred with secondary containment that satisfies the requirements of subsection (4) of this section before it can be returned to service, unless the source of the leak is an aboveground portion of a tank system that can be inspected visually. If the source is an aboveground component that can be inspected visually, the component must be repaired and may be returned to service without secondary containment as long as the requirements of (f) of this subsection are satisfied. If a component is replaced to comply with the requirements of this subitem, that component must satisfy the requirements for new tank systems or components in subsections (3) and (4) of this section. Additionally, if a leak has occurred in any portion of a tank system component that is not readily accessible for visual inspection (e.g., the bottom of an inground or onground tank), the entire component must be provided with secondary containment in accordance with subsection (4) of this section prior to being returned to use.
(f) Certification of major repairs. If the owner/operator has repaired a tank system in accordance with (e) of this subsection, and the repair has been extensive (e.g., installation of an internal liner; repair of a ruptured primary containment or secondary containment vessel), the tank system must not be returned to service unless the owner/operator has obtained a certification by an independent, qualified, registered, professional engineer in accordance with WAC 173-303-810 (13)(a) that the repaired system is capable of handling dangerous wastes without release for the intended life of the system. This certification must be submitted to the department within seven days after returning the tank system to use.
Note:
See WAC 173-303-320 for the requirements necessary to remedy a failure. Also, 40 C.F.R. Part 302 may require the owner or operator to notify the National Response Center of certain releases.
(8) Closure and post-closure care.
(a) At closure of a tank system, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated soils, and structures and equipment contaminated with waste, and manage them as dangerous waste, unless WAC 173-303-070 (2)(a) applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for tank systems must meet all of the requirements specified in WAC 173-303-610 and 173-303-620.
(b) If the owner or operator demonstrates that not all contaminated soils can be practicably removed or decontaminated as required in (a) of this subsection, then the owner or operator must close the tank system and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills (see WAC 173-303-665(6)). In addition, for the purposes of closure, post-closure, and financial responsibility, such a tank system is then considered to be a landfill, and the owner or operator must meet all of the requirements for landfills specified in WAC 173-303-610 and 173-303-620.
(c) If an owner or operator has a tank system that does not have secondary containment that meets the requirements of subsection (4)(b) through (f) of this section and is not exempt from the secondary containment requirements in accordance with subsection (4)(g) of this section, then:
(i) The closure plan for the tank system must include both a plan for complying with (a) of this subsection and a contingent plan for complying with (b) of this subsection.
(ii) A contingent post-closure plan for complying with (b) of this subsection must be prepared and submitted as part of the permit application.

(iv) Financial assurance must be based on the cost estimates in (c)(iii) of this subsection.
(v) For the purposes of the contingent closure and post-closure plans, such a tank system is considered to be a landfill, and the contingent plans must meet all of the closure, post-closure, and financial responsibility requirements for landfills under this chapter (WAC 173-303-610 and 173-303-620).
(9) Special requirements for ignitable or reactive wastes.
(a) Ignitable or reactive waste must not be placed in tank systems unless:
(i) The waste is treated, rendered, or mixed before or immediately after placement in the tank system so that the resulting waste, mixture, or dissolution of material no longer meets the definition of ignitable or reactive waste under WAC 173-303-090, and 173-303-395 (1)(b) is complied with; or
(ii) The waste is stored or treated in such a way that it is protected from any material or conditions which may cause the waste to ignite or react; or
(iii) The tank system is used solely for emergencies.
(b) The owner or operator of a facility which treats or stores ignitable or reactive waste in tanks must locate the tanks in a manner equivalent to the National Fire Protection Association's buffer zone requirements for tanks, contained in NFPA 30 "Flammable and Combustible Liquids Code," or as required by state and local fire codes when such codes are more stringent. The owner or operator must also comply with the requirements of WAC 173-303-395 (1)(d).

AMENDATORY SECTION(Amending WSR 15-01-123, filed 12/18/14, effective 1/18/15)
WAC 173-303-650Surface impoundments.
(1) Applicability. The regulations in this section apply to owners and operators of facilities that use surface impoundments to treat, store, or dispose of dangerous waste.
(2) Design and operating requirements.
(a)(i) Any surface impoundment that is not covered by (j) of this subsection must have a liner for all portions of the impoundment (except for an existing portion of a surface impoundment). The liner must be designed, constructed, and installed to prevent any migration of wastes out of the impoundment to the adjacent subsurface soil or groundwater or surface water at any time during the active life (including the closure period) of the impoundment. The liner may be constructed of materials that may allow wastes to migrate into the liner (but not into the adjacent subsurface soil or groundwater or surface water) during the active life of the facility, provided that the impoundment is closed in accordance with subsection (6)(a)(i) of this section. For impoundments that will be closed in accordance with subsection (6)(a)(ii) of this section, the liner must be constructed of materials that can prevent wastes from migrating into the liner during the active life of the facility. The liner must be:
(A) Constructed of materials that have appropriate chemical properties and sufficient strength and thickness to prevent failure due to pressure gradients (including static head and external hydrogeologic forces), physical contact with the waste or leachate to which they are exposed, climatic conditions, the stress of installation, and the stress of daily operation;
(B) Placed upon a foundation or base capable of providing support to the liner and resistance to pressure gradients above and below the liner to prevent failure of the liner due to settlement, compression, or uplift;
(C) Installed to cover all surrounding earth likely to be in contact with the waste or leachate; and
(D) For EHW management, the owner or operator must submit an engineering report with their permit application under WAC 173-303-806(4) stating the basis for selecting the liner(s). The report must be certified by an independent, qualified registered professional engineer.
(ii) The owner or operator of a new surface impoundment installed after October 31, 1984, and in which liquid EHW is managed must:
(A) Install a double lined system which incorporates the specifications of subsection (3)(a), (b), and (c) of this section; and
(B) Must comply with either the groundwater monitoring requirements of WAC 173-303-645, or the unsaturated zone monitoring requirements of WAC 173-303-655(6).
(b) The owner or operator will be exempted from the requirements of (a) of this subsection, if the department finds, based on a demonstration by the owner or operator, that alternate design and operating practices, together with location characteristics, will prevent the migration of any dangerous constituents listed in WAC 173-303-9905, or which otherwise cause his wastes to be regulated under this chapter, into the groundwater or surface water at any future time. In deciding whether to grant an exemption, the department will consider:
(i) The nature and quantity of the wastes;
(ii) The proposed alternate design and operation;
(iii) The hydrogeologic setting of the facility, including the attenuative capacity and thickness of the liners and soils present between the impoundment and groundwater or surface water; and
(iv) All other factors which would influence the quality and mobility of the leachate produced and the potential for it to migrate to groundwater or surface water.
(c) A surface impoundment must be designed, constructed, maintained, and operated to prevent overtopping resulting from normal or abnormal operations; overfilling; wind and wave action; rainfall; run-on; malfunctions of level controllers, alarms, and other equipment; and human error.
(d) A surface impoundment must be designed so that any flow of waste into the impoundment can be immediately shut off in the event of overtopping or liner failure.
(e) A surface impoundment must be designed to repel birds.
(f) A surface impoundment must have dikes that are designed, constructed, and maintained with sufficient structural integrity to prevent their failure. In ensuring structural integrity, it must not be presumed that the liner system will function without leakage during the active life of the unit.
(g) Earthen dikes must be kept free of:
(i) Perennial woody plants with root systems which could weaken its structural integrity; and
(ii) Burrowing mammals which could weaken its structural integrity or create leaks through burrows.
(h) Earthen dikes must have a protective cover, such as grass, shale or rock to minimize wind and water erosion and to preserve their structural integrity.
(i) The department will specify in the permit all design and operating practices that are necessary to ensure that the requirements of this subsection are satisfied.
(j) The owner or operator of each new surface impoundment unit on which construction commences after January 29, 1992, each lateral expansion of a surface impoundment unit on which construction commences after July 29, 1992, and each replacement of an existing surface impoundment unit that is to commence reuse after July 29, 1992, must install two or more liners and a leachate collection and removal system between such liners. "Construction commences" is as defined in WAC 173-303-040 under "existing TSD facility."
(i) The liner system must include:
(A) A top liner designed and constructed of materials (e.g., a geomembrane) to prevent the migration of dangerous constituents into such liner during the active life and post-closure care period; and
(B) A composite bottom liner, consisting of at least two components. The upper component must be designed and constructed of materials (e.g., a geomembrane) to prevent the migration of dangerous constituents into this component during the active life and post-closure care period. The lower component must be designed and constructed of materials to minimize the migration of dangerous constituents if a breach in the upper component were to occur. The lower component must be constructed of at least 3 feet (91 cm) of compacted soil material with a hydraulic conductivity of no more than 1 x 10-7 cm/sec.
(ii) The liners must comply with (a)(i)(A), (B), and (C) of this subsection.
(iii) The leachate collection and removal system between the liners, and immediately above the bottom composite liner in the case of multiple leachate collection and removal systems, is also a leak detection system. This leak detection system must be capable of detecting, collecting, and removing leaks of dangerous constituents at the earliest practicable time through all areas of the top liner likely to be exposed to waste or leachate during the active life and post-closure care period. The requirements for a leak detection system in this paragraph are satisfied by installation of a system that is, at a minimum:
(A) Constructed with a bottom slope of one percent or more;
(B) Constructed of granular drainage materials with a hydraulic conductivity of 1 x 10-1 cm/sec or more and a thickness of 12 inches (30.5 cm) or more; or constructed of synthetic or geonet drainage materials with a transmissivity of 3 x 10-4 m2/sec or more;
(C) Constructed of materials that are chemically resistant to the waste managed in the surface impoundment and the leachate expected to be generated, and of sufficient strength and thickness to prevent collapse under the pressures exerted by overlying wastes and any waste cover materials or equipment used at the surface impoundment;
(D) Designed and operated to minimize clogging during the active life and post-closure care period; and
(E) Constructed with sumps and liquid removal methods (e.g., pumps) of sufficient size to collect and remove liquids from the sump and prevent liquids from backing up into the drainage layer. Each unit must have its own sump(s). The design of each sump and removal system must provide a method for measuring and recording the volume of liquids present in the sump and of liquids removed.
(iv) The owner or operator will collect and remove pumpable liquids in the sumps to minimize the head on the bottom liner.
(v) The owner or operator of a leak detection system that is not located completely above the seasonal high water table must demonstrate that the operation of the leak detection system will not be adversely affected by the presence of groundwater.
(k) The department may approve alternative design or operating practices to those specified in (j) of this subsection if the owner or operator demonstrates to the department that such design and operating practices, together with location characteristics:
(i) Will prevent the migration of any dangerous constituent into the groundwater or surface water at least as effectively as the liners and leachate collection and removal system specified in (j) of this subsection; and
(ii) Will allow detection of leaks of dangerous constituents through the top liner at least as effectively.
(l) The double liner requirement set forth in (j) of this subsection may be waived by the department for any monofill, if:
(i) The monofill contains only dangerous wastes from foundry furnace emission controls or metal casting molding sand, and such wastes do not contain constituents which would render the wastes dangerous for reasons other than the toxicity characteristic in WAC 173-303-090(8) or the toxicity criteria at WAC 173-303-100(5); and
(ii)(A) The monofill has at least one liner for which there is no evidence that such liner is leaking. For the purposes of this paragraph, the term "liner" means a liner designed, constructed, installed, and operated to prevent dangerous waste from passing into the liner at any time during the active life of the facility, or a liner designed, constructed, installed, and operated to prevent dangerous waste from migrating beyond the liner to adjacent subsurface soil, groundwater, or surface water at any time during the active life of the facility. In the case of any surface impoundment which has been exempted from the requirements of (j) of this subsection on the basis of a liner designed, constructed, installed, and operated to prevent dangerous waste from passing beyond the liner, at the closure of such impoundment, the owner or operator must remove or decontaminate all waste residues, all contaminated liner material, and contaminated soil to the extent practicable. If all contaminated soil is not removed or decontaminated, the owner or operator of such impoundment will comply with appropriate post-closure requirements, including but not limited to groundwater monitoring and corrective action;
(B) The monofill is located more than one-quarter mile from an underground source of drinking water (as that term is defined in WAC 173-303-040); and
(C) The monofill is in compliance with generally applicable groundwater monitoring requirements for facilities with permits under RCRA section 3005(c); or
(iii) The owner or operator demonstrates that the monofill is located, designed and operated so as to assure that there will be no migration of any dangerous constituent into groundwater or surface water at any future time.
(m) The owner or operator of any replacement surface impoundment unit is exempt from (j) of this subsection if:
(i) The existing unit was constructed in compliance with the design standards of sections 3004 (o)(1)(A)(i) and (o)(5) of the Resource Conservation and Recovery Act; and
(ii) There is no reason to believe that the liner is not functioning as designed.
(3) Reserve.
(4) Monitoring and inspection.
(a) During construction and installation, liners (except in the case of existing portions of surface impoundments exempt from subsection (2)(a)(i) of this section) and cover systems (e.g., membranes, sheets, or coatings) must be inspected for uniformity, damage, and imperfections (e.g., holes, cracks, thin spots, or foreign materials). Immediately after construction or installation:
(i) Synthetic liners and covers must be inspected to ensure tight seams and joints and the absence of tears, punctures, or blisters; and
(ii) Soil-based and admixed liners and covers must be inspected for imperfections including lenses, cracks, channels, root holes, or other structural nonuniformities that may cause an increase in the permeability of the liner or cover.
(b) While a surface impoundment is in operation, it must be inspected weekly and after storms to detect evidence of any of the following:
(i) Deterioration, malfunctions, or improper operation of overtopping control systems;
(ii) Sudden drops in the level of the impoundment's contents; and
(iii) Severe erosion or other signs of deterioration in dikes or other containment devices.
(c) Prior to the issuance of a permit, and after any extended period of time (at least six months) during which the impoundment was not in service, the owner or operator must obtain a certification from an independent qualified registered professional engineer that the impoundment's dike, including that portion of any dike which provides freeboard, has structural integrity. The certification must establish, in particular, that the dike:
(i) Will withstand the stress of the pressure exerted by the types and amounts of wastes to be placed in the impoundment; and
(ii) Will not fail due to scouring or piping, without dependence on any liner system included in the surface impoundment construction.
(d)(i) An owner or operator required to have a leak detection system under subsection (2)(j) or (k) of this section must record the amount of liquids removed from each leak detection system sump at least once each week during the active life and closure period.
(ii) After the final cover is installed, the amount of liquids removed from each leak detection system sump must be recorded at least monthly. If the liquid level in the sump stays below the pump operating level for two consecutive months, the amount of liquids in the sumps must be recorded at least quarterly. If the liquid level in the sump stays below the pump operating level for two consecutive quarters, the amount of liquids in the sumps must be recorded at least semi annually. If at any time during the post-closure care period the pump operating level is exceeded at units on quarterly or semiannual recording schedules, the owner or operator must return to monthly recording of amounts of liquids removed from each sump until the liquid level again stays below the pump operating level for two consecutive months.
(iii) "Pump operating level" is a liquid level proposed by the owner or operator and approved by the department based on pump activation level, sump dimensions, and level that avoids backup into the drainage layer and minimizes head in the sump.
(5) Emergency repairs; contingency plans.
(a) A surface impoundment must be removed from service in accordance with (b) of this subsection when:
(i) Unexpected changes of liquid levels occur; or
(ii) The dike leaks.
(b) When a surface impoundment must be removed from service as required by (a) of this subsection, the owner or operator must:
(i) Immediately shut off the flow or stop the addition of wastes into the impoundment;
(ii) Immediately contain any surface leakage which has occurred or is occurring;
(iii) Immediately stop the leak;
(iv) Take any other necessary steps to stop or prevent catastrophic failure;
(v) Empty the impoundment, if a leak cannot be stopped by any other means; and
(vi) Notify the department of the problem in writing within seven days after detecting the problem.
(c) As part of the contingency plan required in WAC 173-303-340 through 173-303-360, the owner or operator must specify:
(i) A procedure for complying with the requirements of (b) of this subsection; and
(ii) A containment system evaluation and repair plan describing: Testing and monitoring techniques; procedures to be followed to evaluate the integrity of the containment system in the event of a possible failure; description of a schedule of actions to be taken in the event of a possible failure; and the repair techniques and materials (and their availability) to be used in the event of leakage due to containment system failure or deterioration which does not require the impoundment to be removed from service.
(d) No surface impoundment that has been removed from service in accordance with the requirements of this section may be restored to service unless the portion of the impoundment which was failing is repaired and the following steps are taken:
(i) If the impoundment was removed from service as the result of actual or imminent dike failure, the dike's structural integrity must be recertified in accordance with subsection (4)(c) of this section;
(ii) If the impoundment was removed from service as the result of a sudden drop in the liquid level, then:
(A) For any existing portion of the impoundment, a liner must be installed in compliance with subsection (2)(a)(i) or (3) of this section; and
(B) For any other portion of the impoundment, the repaired liner system must be certified by an independent qualified registered professional engineer as meeting the design specifications approved in the permit.
(e) A surface impoundment that has been removed from service in accordance with the requirements of this section and that is not being repaired must be closed in accordance with the provisions of subsection (6) of this section.
(6) Closure and post-closure care.
(a) At closure, the owner or operator must:
(i) Remove or decontaminate all dangerous waste and dangerous waste residues, contaminated containment system components (liners, etc.), contaminated subsoils, and structures and equipment contaminated with dangerous waste and leachate, and manage them as dangerous waste; or
(ii) If the surface impoundment will be closed as a landfill, except that this option is prohibited if EHW would remain in the closed unit(s):
(A) Eliminate free liquids by removing liquid wastes or solidifying the remaining wastes and waste residues;
(B) Stabilize remaining wastes to a bearing capacity sufficient to support a final cover; and
(C) Cover the surface impoundment with a final cover designed and constructed to:
(I) Provide long-term minimization of the migration of liquids through the closed impoundment with a material that has a permeability less than or equal to the permeability of any bottom liner system or natural subsoils present;
(II) Function with minimum maintenance;
(III) Promote drainage and minimize erosion or abrasion of the final cover; and
(IV) Accommodate settling and subsidence so that the cover's integrity is maintained.
(b) If some waste residues or contaminated materials are left in place at final closure (except that no EHW may ever be left in place), the owner or operator must comply with all post-closure requirements contained in WAC 173-303-610 (7), (8), (9), and (10), including maintenance and monitoring throughout the post-closure care period (specified in the permit). The owner or operator must:
(i) Maintain the integrity and effectiveness of the final cover, including making repairs to the cap as necessary to correct the effects of settling, subsidence, erosion, or other events;

(c)(i) If an owner or operator plans to close a surface impoundment in accordance with (a)(i) of this subsection, and the impoundment does not comply with the liner requirements of subsection (2)(a)(i) of this section, and is not exempt from them in accordance with subsection (2)(b) of this section, then:
(A) The closure plan for the impoundment under WAC 173-303-610(3) must include both a plan for complying with (a)(i) of this subsection, and a contingent plan for complying with (a)(ii) of this subsection in case not all contaminated subsoils can be practicably removed at closure; and
(B) The owner or operator must prepare a contingent post-closure plan under WAC 173-303-610(8) for complying with (b) of this subsection in case not all contaminated subsoils can be practicably removed at closure.
(ii) The cost estimates calculated under WAC 173-303-620 (3) and (5) for closure and post-closure care of an impoundment subject to (c) of this subsection must include the cost of complying with the contingent closure plan and the contingent post-closure plan, but are not required to include the cost of expected closure under (a)(i) of this subsection.
Reserve.
(7) Special requirements for ignitable or reactive waste. Ignitable or reactive waste must not be placed in a surface impoundment, unless the waste and impoundment satisfy all applicable requirements of WAC 173-303-140 (2)(a), and:
(a) The waste is treated, rendered, or mixed before or immediately after placement in the impoundment so that:
(i) The resulting waste, mixture, or dissolution of material no longer meets the definition of ignitable or reactive waste under WAC 173-303-090; and
(ii) WAC 173-303-395 (1)(b) is complied with; or
(b) The waste is managed in such a way that it is protected from any material or conditions which may cause it to ignite or react; or
(c) The surface impoundment is used solely for emergencies.
(8) Special requirements for incompatible wastes. Incompatible wastes and materials must not be placed in the same surface impoundment, unless WAC 173-303-395 (1)(b) is complied with.
(9) Special requirements for dangerous wastes F020, F021, F022, F023, F026, and F027.
(a) The wastes F020, F021, F022, F023, F026, or F027 must not be placed in a surface impoundment unless the owner or operator operates the surface impoundment in accordance with a management plan for these wastes that is approved by the department pursuant to the standards set out in this subsection, and in accord with all other applicable requirements of this section. The factors to be considered are:
(i) The volume, physical, and chemical characteristics of the wastes, including their potential to migrate through soil or to volatilize or escape into the atmosphere;
(ii) The attenuative properties of underlying and surrounding soils or other materials;
(iii) The mobilizing properties of other materials co-disposed with these wastes; and
(iv) The effectiveness of additional treatment, design, or monitoring techniques.
(b) The department may determine that additional design, operating, and monitoring requirements are necessary in order to reduce the possibility of migration of these wastes to groundwater, surface water, or air so as to protect human health and the environment.
(10) Action leakage rate.
(a) The department must approve an action leakage rate for surface impoundment units subject to WAC 173-303-650 (2)(j) or (k). The action leakage rate is the maximum design flow rate that the leak detection system (LDS) can remove without the fluid head on the bottom liner exceeding 1 foot. The action leakage rate must include an adequate safety margin to allow for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness of drainage material), construction, operation, and location of the LDS, waste and leachate characteristics, likelihood and amounts of other sources of liquids in the LDS, and proposed response actions (e.g., the action leakage rate must consider decreases in the flow capacity of the system over time resulting from siltation and clogging, rib layover and creep of synthetic components of the system, overburden pressures, etc.).
(b) To determine if the action leakage rate has been exceeded, the owner or operator must convert the weekly or monthly flow rate from the monitoring data obtained under WAC 173-303-650 (4)(d) to an average daily flow rate (gallons per acre per day) for each sump. Unless the department approves a different calculation, the average daily flow rate for each sump must be calculated weekly during the active life and closure period, and if the unit is closed in accordance with WAC 173-303-650 (6)(b), monthly during the post-closure care period when monthly monitoring is required under WAC 173-303-650 (4)(d).
(11) Response actions.
(a) The owner or operator of surface impoundment units subject to subsection (2)(j) or (k) of this section must have an approved response action plan before receipt of waste. The response action plan must set forth the actions to be taken if the action leakage rate has been exceeded. At a minimum, the response action plan must describe the actions specified in (b) of this subsection.
(b) If the flow rate into the leak detection system exceeds the action leakage rate for any sump, the owner or operator must:
(i) Notify the department in writing of the exceedance within seven days of the determination;
(ii) Submit a preliminary written assessment to the department within fourteen days of the determination, as to the amount of liquids, likely sources of liquids, possible location, size, and cause of any leaks, and short-term actions taken and planned;
(iii) Determine to the extent practicable the location, size, and cause of any leak;
(iv) Determine whether waste receipt should cease or be curtailed, whether any waste should be removed from the unit for inspection, repairs, or controls, and whether or not the unit should be closed;
(v) Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks; and
(vi) Within thirty days after the notification that the action leakage rate has been exceeded, submit to the department the results of the analyses specified in (b) (iii), (iv), and (v) of this subsection, the results of actions taken, and actions planned. Monthly thereafter, as long as the flow rate in the leak detection system exceeds the action leakage rate, the owner or operator must submit to the department a report summarizing the results of any remedial actions taken and actions planned.
(c) To make the leak and/or remediation determinations in (b)(iii), (iv), and (v) of this subsection, the owner or operator must:
(i) Assess the source of liquids and amounts of liquids by source;
(ii) Conduct a fingerprint, dangerous constituent, or other analyses of the liquids in the leak detection system to identify the source of liquids and possible location of any leaks, and the hazard and mobility of the liquid; and
(iii) Assess the seriousness of any leaks in terms of potential for escaping into the environment; or
(iv) Document why such assessments are not needed.
(12) Air emission standards. The owner or operator must manage all hazardous waste placed in a surface impoundment in accordance with the applicable requirements of 40 C.F.R. Part 264, Subparts AA, BB, and CC, which are incorporated by reference at WAC 173-303-690 through 173-303-692.
(13) Existing and newly regulated surface impoundments. The requirements of 3005 (j)(1) and (6) of the Resource Conservation and Recovery Act (RCRA) of 1976, as amended, are incorporated by reference. Surface impoundments regulated for the first time by a listing or characteristic adopted after November 8, 1984, must comply with new unit requirements or stop dangerous waste activity by four years after the date of adoption of the new listing or characteristic.

AMENDATORY SECTION(Amending WSR 15-01-123, filed 12/18/14, effective 1/18/15)
WAC 173-303-800Permit requirements for dangerous waste management facilities.
(1) The purpose of WAC 173-303-800 through 173-303-840 is to establish the requirements for permits which will allow a dangerous waste facility to operate without endangering the public health and the environment.
(2) The owner/operator of a dangerous waste facility that ((transfers,)) treats, stores, or disposes (TSD) ((or recycles)) dangerous waste must((, when required by this chapter,))have a permit issued, or obtain a permit, in accordance with WAC 173-303-800 through 173-303-840 ((covering)). When required by this chapter, the owner/operator of a dangerous waste facility that transfers or recycles dangerous waste must also obtain a permit, in accordance with this section through WAC 173-303-840. The dangerous waste permit must cover the active life, closure period, groundwater protection compliance period, and for any regulated unit (as defined in WAC 173-303-040) or for any facility which at closure does not meet the removal or decontamination limits of WAC 173-303-610 (2)(b), post-closure care period, unless ((they))the owner/operator can demonstrate closure by removal or decontamination as provided under WAC 173-303-800 (9) and (10), or obtain an enforceable document in lieu of a post-closure permit, as provided under subsection (12) of this section. If a post-closure permit is required, the permit must address applicable groundwater monitoring, unsaturated zone monitoring, corrective action, and post-closure care requirements of this chapter. The denial of a permit for the active life of a dangerous waste management facility or unit does not affect the requirement to obtain a post-closure permit under this section.
(3) TSD facility permits will be granted only if the objectives of the siting and performance standards set forth in WAC 173-303-282 and 173-303-283 are met.
(4) Permits will be issued according to the requirements of all applicable TSD facility standards.
(5) The owner/operator of a TSD facility is responsible for obtaining all other applicable federal, state, and local permits authorizing the development and operation of the TSD facility.
(6) The terms used in regard to permits which are not defined in WAC 173-303-040 have the same meanings as set forth in 40 C.F.R. 270.2.
(7) Exemptions.
(a) A permit for an on-site cleanup action may be exempted as provided in a consent decree or order signed by the department and issued pursuant to chapter 70.105D RCW.
(b) A permit is not required for an on-site cleanup action performed by the department pursuant to chapter 70.105D RCW.
(c) Further exemptions.
(i) A person is not required to obtain a dangerous waste permit for treatment or containment activities taken during immediate response to any of the following situations:
(A) A discharge of a dangerous waste;
(B) An imminent and substantial threat of a discharge of dangerous waste;
(C) A discharge of a material that, when discharged, becomes a dangerous waste;
(D) An immediate threat to human health, public safety, property, or the environment from the known or suspected presence of military munitions, other explosive material, or an explosive device, as determined by an explosive or munitions emergency response specialist as defined in WAC 173-303-040.
(E) In the case of emergency responses involving military munitions, the responding military emergency response specialist's organizational unit must retain records for three years identifying the dates of the response, the responsible persons responding, the type and description of material addressed, and its disposition.
(ii) Any person who continues or initiates dangerous waste treatment or containment activities after the immediate response is over is subject to all applicable requirements of this chapter for those activities.
(iii) Universal waste handlers and universal waste transporters (as defined in WAC 173-303-040) handling the wastes listed below are not required to obtain a dangerous waste permit. These handlers are subject to regulation under WAC 173-303-573, when handling the below listed universal wastes.

(8) Each permit issued under this chapter will contain terms and conditions as the department determines necessary to protect human health and the environment.
(9) Closure by removal. Owners/operators of surface impoundments, land treatment units, and waste piles closing by removal or decontamination under 40 C.F.R. Part 265 standards as referenced by WAC 173-303-400 must obtain a post-closure permit unless they can demonstrate to the department that the closure met the standards for closure by removal or decontamination in WAC 173-303-650(6), 173-303-655(8), or 173-303-660(9), as appropriate, and such removal or decontamination must assure that the levels of dangerous waste or dangerous waste constituents or residues do not exceed standards for closure at 40 C.F.R. Part 264.111, as appropriate. The demonstration may be made in the following ways:
(a) If the owner/operator has submitted a Part B application for a post-closure permit, the owner/operator may request a determination, based on information contained in the application, that 40 C.F.R. Part 264.111 standards for closure by removal were met. If the department believes that 40 C.F.R. Part 264.111 standards were met, the department will notify the public of this proposed decision, allow for public comment, and reach a final determination according to the procedures in subsection (10) of this section.
(b) If the owner/operator has not submitted a Part B application for a post-closure permit, the owner/operator may petition the department for a determination that a post-closure permit is not required because the closure met the applicable 40 C.F.R. Part 264.111 closure standards.
(i) The petition must include data demonstrating that standards for closure by removal or decontamination were met, or it must demonstrate that the unit closed under chapter 173-303 WAC requirements that met or exceeded the applicable 40 C.F.R. Part 264.111 closure-by-removal standard.
(ii) The department will approve or deny the petition according to the procedures outline in subsection (10) of this section.
(10) Procedures for closure equivalency determination.
(a) If a facility owner/operator seeks an equivalency demonstration under subsection (9) of this section, the department will provide the public, through a newspaper notice, the opportunity to submit written comments on the information submitted by the owner/operator within thirty days from the date of the notice. The department will also, in response to a request or at the discretion of the department, hold a public hearing whenever such a hearing might clarify one or more issues concerning the equivalence of the 40 C.F.R. Part 265 closure, as referenced by WAC 173-303-400, to a 40 C.F.R. Part 264.111 closure. The department will give public notice of the hearing at least thirty days before it occurs. (Public notice of the hearing may be given at the same time as notice of the opportunity for the public to submit written comments, and the two notices may be combined.)
(b) The department will determine whether the 40 C.F.R. Part 265 closure met 40 C.F.R. Part 264.111 closure by removal or decontamination requirements within ninety days of its receipt. If the department finds that the closure did not meet the applicable 40 C.F.R. Part 264.111 standards, the department will provide the owner/operator with a written statement of the reasons why the closure failed to meet 40 C.F.R. Part 264.111 standards. The owner/operator may submit additional information in support of an equivalency demonstration within thirty days after receiving such written statement. The department will review any additional information submitted and make a final determination within sixty days.
(c) If the department determines that the facility did not close in accordance with 40 C.F.R. Part 264.111 standards for closure by removal, the facility is subject to post-closure permitting requirements.
(11) The department may require a permittee or an applicant to submit information in order to establish permit conditions under subsection (8) of this section and WAC 173-303-806 (11)(d).
(12) Enforceable documents for post-closure care. At the discretion of the department, an owner or operator may obtain, in lieu of a post-closure permit, an enforceable document imposing the requirements of 40 C.F.R. 265.121 as incorporated by reference in WAC 173-303-400 (3)(a). "Enforceable document" has the same meaning as defined in WAC 173-303-040.
AMENDATORY SECTION(Amending WSR 15-01-123, filed 12/18/14, effective 1/18/15)

Prior to the department issuing a permit, the owner/operator must submit an impact mitigation plan which demonstrates to the satisfaction of the department that the owner/operator will mitigate all probable significant adverse impacts, including economic, due to facility location and operations. The owner/operator must use as a basis for identifying probable significant adverse economic impacts those probable economic impacts identified during a public review process, such as the environmental impact statement scoping process, if applicable.
The plan must include, but is not limited to, a description of what the owner/operator will do to reduce or prevent any probable significant impacts before they occur, to mitigate such impacts should they occur, and to ensure the owner/operator has and will have the financial capability to implement such preventative and mitigative measures. Mitigation measures may include, as an element, financial compensation to adversely affected parties.
This plan may be submitted with environmental reports the department requires for compliance with the State Environmental Policy Act, with the written citizen proponent negotiation report and agreements, or with the Part B permit application. If the plan does not demonstrate that the owner/operator is capable of adequately mitigating the identified probable significant adverse economic impacts, the department will require modification of the plan or of the proposed facility location, or will deny the permit application. The department must be satisfied with the plan prior to the issuance of the permit.

(5) Construction. A person may begin physical construction of a new facility, or of new portions of an existing facility if the new portions would amount to reconstruction under interim status (WAC 173-303-805(7)), only after complying with WAC 173-303-281, submitting Part A and Part B of the permit application and receiving a final facility permit. All permit applications must be submitted at least one hundred eighty days before physical construction is expected to begin.
(6) Reapplications. Any dangerous waste facility with an effective final facility permit must submit a new application one hundred eighty days prior to the expiration date of the effective permit, unless the department grants a later date provided that such date will never be later than the expiration date of the effective permit.
Note:
See public notice requirements at WAC 173-303-281(5).
(7) Continuation of expiring permits.
(a) When the owner/operator submits a timely application for a final facility permit and the application is determined by the department to be complete pursuant to subsection (8) of this section, the facility is allowed to continue operating under the expiring or expired permit until the effective date of the new permit.
(b) When the facility is not in compliance with the conditions of the expiring or expired permit, the department may choose to do any of the following:
(i) Initiate enforcement action based upon the permit which has been continued;
(ii) Issue a notice of intent to deny the new permit. If the permit is denied, the owner or operator would then be required to cease the activities authorized by the continued permit or be subject to enforcement action for operating without a permit;
(iii) Issue a new permit with appropriate conditions; and/or
(iv) Take other actions authorized by this chapter.
(8) Completeness. The department will not issue a final facility permit before receiving a complete application, except for permits by rule or emergency permits. An application for a permit is complete when the department receives an application form and any supplemental information which are completed to the department's satisfaction. The department may consider an application for a permit to be complete notwithstanding the failure of the owner or operator to submit the exposure information described in subsection (12) of this section. The department may deny a permit for the active life of a dangerous waste management facility or unit before receiving a complete application for a permit.
(9) Recordkeeping. Applicants must keep records of all data used to complete the permit applications, and any supplemental information submitted to the department for a period of at least three years from the date the application is signed.
(10) General permit conditions. All final facility permits will contain general permit conditions described in WAC 173-303-810.
(11) Permit duration.
(a) Final facility permits will be effective for a fixed term not to exceed ten years.

(c) The term of a final facility permit will not be extended beyond ten years, unless otherwise authorized under subsection (7) of this section.
(d) Each permit for a land disposal facility will be reviewed by the department five years after the date of permit issuance or reissuance and will be modified as necessary, as provided in WAC 173-303-830(3).
(12) Exposure information. Any Part B permit application submitted by an owner or operator of a facility that stores, treats, or disposes dangerous waste in a surface impoundment or a landfill must be accompanied by information, reasonably ascertainable by the owner or operator, on the potential for the public to be exposed to dangerous wastes or dangerous constituents through releases related to the unit. At a minimum, such information must address:
(a) Reasonably foreseeable potential releases from both normal operations and accidents at the unit, including releases associated with transportation to or from the unit;
(b) The potential pathways of human exposure to dangerous waste or constituents resulting from the releases described under (a) of this subsection; and
(c) The potential magnitude and nature of the human exposure resulting from such releases.
(13) Grounds for denial. A permit application will be denied pursuant to the procedures in WAC 173-303-840 if it is determined that the proposed location and/or activity endangers public health and the environment as demonstrated by the permit applicant's failure to satisfy the performance standards of WAC 173-303-283.
(14) Permit changes. All final facility permits will be subject to the requirements of permit changes, WAC 173-303-830.
(15) Procedures for decision making. Issuance of final facility permits will be subject to the procedures for decision making described in WAC 173-303-840.
(16) Other requirements for final recycling facility permits. In lieu of issuing a final recycling facility permit, the department may, after providing opportunity for public comment in accordance with WAC 173-303-840, defer to a permit already issued under other statutory authority administered by the department (such as the State Water Pollution Control Act, chapter 90.48 RCW, the State Clean Air Act, chapter 70.94 RCW, etc.) which incorporates the requirements of this section, and WAC 173-303-500 through 173-303-525 for recycling facilities.
(17)(a) If the department concludes, based on one or more of the factors listed in (a)(i) through (ix) of this subsection, that compliance with the standards of 40 C.F.R. Part 63, Subpart EEE alone may not be protective of human health or the environment, the department will require the additional information or assessment(s) necessary to determine whether additional controls are necessary to ensure protection of human health and the environment. This includes information necessary to evaluate the potential risk to human health and/or the environment resulting from both direct and indirect exposure pathways. The department may also require a permittee or applicant to provide information necessary to determine whether such an assessment(s) should be required.
The department will base the evaluation of whether compliance with the standards of 40 C.F.R. Part 63, Subpart EEE alone is protective of human health or the environment on factors relevant to the potential risk from a hazardous waste combustion unit, including, as appropriate, any of the following factors:
(i) Particular site-specific considerations such as proximity to receptors (such as schools, hospitals, nursing homes, day care centers, parks, community activity centers, or other potentially sensitive receptors), unique dispersion patterns, etc.;
(ii) Identities and quantities of emissions of persistent, bioaccumulative or toxic pollutants considering enforceable controls in place to limit those pollutants;
(iii) Identities and quantities of nondioxin products of incomplete combustion most likely to be emitted and to pose significant risk based on known toxicities (confirmation of which should be made through emissions testing);
(iv) Identities and quantities of other off-site sources of pollutants in proximity of the facility that significantly influence interpretation of a facility-specific risk assessment;
(v) Presence of significant ecological considerations, such as the proximity of a particularly sensitive ecological area;
(vi) Volume and types of wastes, for example wastes containing highly toxic constituents;
(vii) Other on-site sources of hazardous air pollutants that significantly influence interpretation of the risk posed by the operation of the source in question;
(viii) Adequacy of any previously conducted risk assessment, given any subsequent changes in conditions likely to affect risk; and
(ix) Such other factors as may be appropriate.
(b) Reserved.

I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment.
(d) After receiving a petition for a dangerous waste exemption, the department may request any additional information which it may reasonably require to evaluate the petition.
(e) An exemption will only apply to the waste generated by the particular generator covered by the demonstration and will not apply to waste from any other generator.
(f) The department may exempt only part of the waste for which the demonstration is submitted where there is reason to believe that variability of the waste justifies a partial exemption.
(g) The department may (but will not be required to) grant a temporary exemption before making a final decision under subsection (1) of this section, whenever it finds that there is a substantial likelihood that an exemption will be finally granted.
(h) Any waste for which an exemption is sought will remain designated and be subject to the applicable requirements of this chapter until the generator of the waste is notified by the department that his waste is exempt.
(4) Petition for exclusion.
(a) Any generators seeking exclusion of a class of similar or identical wastes under WAC 173-303-071, excluded categories of waste, may petition the department for exclusion. To be successful, the generator(s) must make the demonstrations required in WAC 173-303-072(6) for all those wastes generated in the state which might be excluded pursuant to granting a petition submitted under this subsection. No class of wastes will be excluded if any of the wastes are regulated as hazardous waste under 40 C.F.R. Part 261.
(b) Each petition for exclusion must include the information required by subsections (1) and (3)(c) of this section and any other information required by the department.
(c) After receiving a petition for exclusion, the department may request any additional information it deems necessary to evaluate the petition.
(5) Petition for designation change. The provisions of (a)(i) of this subsection do not apply to any dangerous waste which is also designated as a hazardous waste under 40 C.F.R. Part 261, Subpart D.
(a) A generator may petition the department to change the designation of his waste as follows:
(i) A waste which is designated only for toxicity pursuant to WAC 173-303-100 but which is toxic solely because it is highly acidic or basic (i.e., due to high or low pH) may be subject only to the requirements for corrosive dangerous wastes, provided that the generator can demonstrate this fact to the department's satisfaction through information provided under (b) of this subsection; and
(ii) A waste which is designated EHW may be redesignated DW, provided that the generator can demonstrate that such redesignation is appropriate through information provided under (b) of this subsection.
(b) A petition under this subsection must include:
(i) The information required by subsections (1) and (3)(c) of this section; and
(ii) Such other information as required by the department.
(c) A designation change under this subsection will become effective only after the department has approved the change and notified the generator of such approval.
(6) Petitions to allow land disposal of a waste restricted under WAC 173-303-140.
(a) Any person seeking a land disposal restriction exemption allowed under WAC 173-303-140(6) must submit a petition to the department. The petition must include the following general information:
(i) The petitioner's name and address;
(ii) A statement of the petitioner's interest in the proposed action;
(iii) A description of the proposed action;
(iv) A statement of the need and justification for the proposed action;
(v) An identification of the specific waste and the specific land disposal unit for which the exemption is desired;
(vi) A waste analysis to describe fully the chemical and physical characteristics of the subject waste. All waste and environmental sampling, test, and analysis data must be accurate and reproducible to the extent that state-of-the-art techniques allow; and
(vii) A quality assurance and quality control plan that addresses all sampling and testing aspects of the information provided in the petition.
(b) In addition to the general information requirements in subsection (a) of this section, the following specific information must be provided in the petition for individual case-by-case exemptions.
(i) Petition for land disposal exemption for treatment residuals. Petitions for exemption of treatment residuals, as allowed under WAC 173-303-140 (6)(a), must:
(A) Provide the type of waste management or treatment method applied to the waste and the rationale for selecting this method as the best achievable management method; and
(B) Document that the land disposal of the treatment residual would not pose a greater risk to public health and the environment than land disposal of the original wastes, including an analysis of the treatment residuals to fully describe their chemical and physical characteristics; and
(C) Provide the management alternatives for the treatment residuals and the factors which, if an exemption is not granted, would prevent the utilization of the best achievable management method for the original dangerous waste.
(ii) Petition for economic hardship exemption. Petitions for exemption on the basis of economic hardship, as allowed under WAC 173-303-140 (6)(b), must:
(A) Supply the current management costs and the projected management costs to comply with the requirements of WAC 173-303-140; and
(B) Provide the source of information utilized in determining the economic estimates; and
(C) Provide a discussion of how the projected compliance costs would impose an unreasonable economic burden.
(iii) Petition for leachable inorganic waste exemption. Petitions for exemption of leachable inorganic wastes, as allowed under WAC 173-303-140 (6)(c), must:
(A) Provide information demonstrating that the stabilization of the dangerous waste is less protective of public health and the environment than landfilling; or
(B) Provide a list of stabilization facilities that could accept the dangerous waste and information demonstrating that they do not have available capacity to stabilize the waste; or
(C) Provide information describing the types of stabilization utilized which did not reduce the solubility and mobility of the dangerous waste constituents and describe any other stabilization methods that have been considered but not utilized.
(iv) Petition for organic/carbonaceous waste exemption. Petitions for exemption of organic/carbonaceous wastes, as allowed under WAC 173-303-140 (6)(c), must:
