PROPOSED RULES

DEPARTMENT OF ECOLOGY

[Order 97-30--Filed October 31, 1997, 10:35 a.m.]

Original Notice.

Preproposal statement of inquiry was filed as WSR 97-18-049.

Title of Rule: Chapter 173-308 WAC, Biosolids management.

Purpose: To implement new rules for biosolids management; regulate treatment related to beneficial use, beneficial uses, and disposal of biosolids in municipal solid waste landfills.

Statutory Authority for Adoption: RCW 70.95J.020 and 70.95.255.

Statute Being Implemented: Chapter 70.95J RCW, Municipal sewage sludge--Biosolids.

Summary: RCW 70.95J.020 requires the state to adopt a rule for biosolids management. RCW 70.95.255 requires label and notification requirements for biosolids sold or given away to the public. The proposed biosolids management rule includes technical standards, management requirements, and a permit system including public notice and applicable fees. The rule addresses beneficial uses of biosolids and also disposal of biosolids in municipal solid waste landfills. The rule is intended to meet requirements established under the Federal Clean Water Act.

Reasons Supporting Proposal: The rule is required by statute. The rule updates and replaces an existing state program that is fifteen years old and no longer in compliance with newer federal regulations. The proposed rule reflects newer science which is generally more acceptable to the regulated community.

Name of Agency Personnel Responsible for Drafting: Kyle Dorsey, 300 Desmond Drive, Lacey, (360) 407-6107; Implementation: Jim Pendowski, 300 Desmond Drive, Lacey, (360) 407-6103; and Enforcement: Regional offices, Lacey, Yakima, Spokane, Bellevue.

Name of Proponent: Washington State Department of Ecology, governmental.

Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: The department will work with local jurisdictional health departments to delegate appropriate authorities to the local level. The department plans to seek delegation of federal program authority after the state rule is in place. After adoption, in accordance with chapter 70.95J RCW the department will begin working with local health departments and the regulated community to investigate the feasibility of modifying the fee schedule to support delegated health departments and to reduce local health department fees paid by permittees.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: The rule is intended to update the current state program and bring it into line with federal program requirements. The rule establishes requirements for biosolids that are applied to land or that are disposed of in a municipal solid waste landfill. It includes requirements for biosolids treatment, quality, monitoring, management, recordkeeping, reporting, and general program administration. It also includes a system of permitting and fees. The rule mainly affects publicly owned sewage treatment plants. It also applies to some private sector facilities including centralized biosolids and septage treatment facilities that carry out treatment processes such as composting and alkaline stabilization, and private lands where biosolids are applied. Implementation of the rule will result in a new system of regulation for biosolids, which have previously been managed under solid waste laws.

Proposal does not change existing rules. The proposal does not directly change existing rules. However, biosolids have been previously regulated as solid waste under chapter 70.95 RCW, chapter 173-304 WAC, and local solid waste ordinances. Under chapter 70.95J RCW, materials meeting the state definition of biosolids will no longer be solid waste, and therefore will not be subject to regulation under solid waste laws. The agency plans to revise chapter 173-304 WAC, Minimum functional standards for solid waste handling, under which biosolids have been previously regulated, in order to clarify the proper regulatory authorities for biosolids management.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

Small Business Economic Impact Statement


The Regulatory Fairness Act (chapter 19.85 RCW) requires that proposed rule-making actions be evaluated for disproportionate burdens upon small versus large businesses. If any are found, mitigation is to be provided if legal or feasible under the statute being implemented. The evaluation of the above-referenced rule indicates that cost impacts on small firms are not disproportionate, or are minor.

background: The proposed rule establishes a biosolids management program within the Department of Ecology as authorized by chapters 70.95 and 70.95J RCW. It is also the basis for delegation of regulatory authority from the United States Environmental Protection Agency (EPA). As such, it is based on and comparable in large measure to federal rules, notably 40 CFR 501 and 503, or other state rules or statutes. In addition, much of the regulated community consists of publicly owned wastewater treatment works and, thus, falls beyond the scope of this analysis. This discussion focusses on the more limited degree in which the proposed rule is substantively different from federal requirements and in which these differences impact businesses within the private sector of Washington's economy.

impacted industries: Private sector businesses affected by the proposed rule may be found in the following sectors:

SIC 2875 Fertilizers, mixing only (compost producers)

SIC 4952 Sewerage systems (privately owned treatment works, centralized septage collection facilities)

SIC 7699 Repair shops and related services not elsewhere classified (septic tank cleaning services)

Note that septic tank cleaning and septage hauling firms that take tank contents to a treatment works or centralized septage collection facility would not fall under the proposed rule; the facility to which the septage is taken would do so. Only those septic tank cleaning firms that directly land apply septage would be impacted by the rule. Additionally, the proposed rule recognizes entities called "beneficial use facilities." These are biosolids land application sites where owners or operators have chosen to come under the rule and to obtain a permit in order to facilitate/encourage biosolids delivery from one or more sources. Their inclusion under the proposed rule is optional on their part and entirely voluntary. As such, they will not be considered further in this discussion.

impacts - septic tank cleaning and septage hauling: The analysis described here utilized information from the EPA Regulatory Impact Analysis of the Part 503 Sewage Sludge Regulation: Final (USEPA, 1993) and direct consultation with a number of individuals associated with impacted businesses and industries in Washington (individual names withheld to prevent disclosure of proprietary information). All estimated dollar values developed from the former have been adjusted for inflation.

Estimated cost impacts upon small and large domestic septic tank cleaning and septage hauling firms that land apply are displayed in the following table. Additional discussion, and consideration of impacts on privately owned treatment works and compost producers, follows. All capital costs have been annualized as in the EPA regulatory impact analysis (RIA) at twelve percent over five years. The RIA and local industry representatives both characterize this industry as containing a large number of very small firms having no employees other than the owner-operator and a very small number of larger firms having five or more employees. In some cases, nationally franchised entities (e.g., Roto-Rooter) may also provide septic tank cleaning services. Septic tank cleaning may also be offered as an additional service by firms in other sectors, e.g., plumbing. The results displayed here assume that small firms have one employee and large firms have seven employees.

impacts on septic tank cleaning and septage hauling firms

(1997 $'s per year per firm)


Requirement Small Firms Large Firms

Recordkeeping/reporting $ 20 $ 180

Screening/grinding 670 4,800

Permit/permit fee 0 390

Total estimated costs $ 690 $ 5,370

Costs per employee $ 690 $ 767

Discussion: It is important to note that, in many cases, firms in this industry are already operating under local regulatory and recordkeeping/reporting requirements and local permit and permit fee systems. In such cases, the proposed rule may not represent a net increase in burdens or costs (except as noted below). Indeed, in some respects, the proposed state program may be more efficient.

The proposed state rule requires, in WAC 173-308-270(3) a greater degree of pathogen control and site management/access restriction on land-applied "Class II domestic septage" (material removed from portable toilets, type III marine sanitation devices, etc.) However, the state rule also allows for some mixing of such septage with material taken from domestic septic tanks and the like in the definition of "Class I domestic septage" (see WAC 173-308-080), for which the requirements proposed here are substantially similar to the federal rules except as described here. Thus, for the most part, the additional state requirement would take effect only in those cases where loads of septage consisting entirely of Class II domestic septage are land applied. This is judged to be a very unlikely event and, hence, is not considered in the impact estimates displayed above.

Recordkeeping requirements for land appliers of domestic septage are included in the federal rule (as well as under currently applied local authority). The proposed state rule adds requirements for records to be kept of the source(s) and class(es) of septage applied to the land, and the way in which site management and access restriction requirements are met (see WAC 173-308-290(6)). Tracking these items and including the information with other required records imposes minimal additional expense, and is included with reporting costs.

Reporting is not required in the federal rule except for treatment plants that require pretreatment of sewage, those serving populations of 10,000 or more, or those having a design flow rate equal to or greater than one million gallons per day. Other entities, including septage haulers, are required to keep records as noted above and to make the information available upon the request of the regulatory authority. The proposed state rule echoes this, but does impose a requirement that entities applying domestic septage to land provide annual reports of the number of gallons of septage applied and the number of acres of land affected during the previous year (WAC 173-308-295(3)). Since this is information that is collected in any case, preparing the annual report is a straightforward clerical function. The costs shown above for septic tank cleaning firms were developed using information in the RIA.

Screening or grinding of septage before land application (WAC 173-308-270(2)) is a state addition to requirements in the federal rule. Although truck-mounted units for use at the application site may become available, it is assumed here that -- for the present -- this would be done by using tanks and screening units. Discussions with local industry representatives indicate that screening units cost approximately $2,000 each (materials and labor) and that there is a plentiful supply of suitable used tanks of various sizes available at a cost of approximately five cents per gallon of capacity. It was assumed here that septage haulers would size their tankage to correspond to their average daily volume as reported in the RIA. The costs shown in the table are the annualized costs of that capital investment plus estimated costs of disposal of the screened out debris.

Permits and permit fees are, as noted above, in large measure a potential shift from existing local systems to a state program. The local industry representatives consulted for this analysis have estimated that the proposed state system (see WAC 173-308-310 and 173-308-320) should impose no greater burdens and costs than existing local arrangements. Further, the Department of Ecology intends to issue one or more general permits under the proposed rule (as well as providing for individual permits or continuation of local coverage under suitable delegation arrangements). Entities seeking coverage under a general permit may be able to reduce some of the public notification and hearings/meeting costs now incurred under existing arrangements (depending on how land application site plans are handled) and may be able to obtain coverage for up to five years compared with what is now generally an annual permitting process.

For these reasons, and because the information required in an application for a state permit is not likely to be significantly more extensive than that required under existing federal and local programs, the costs of preparing and submitting a state program permit application are assumed to be no greater than now incurred under local jurisdiction. (Small vs. large business implications of state permitting will be further considered, as needed, in the analysis of the general permit required under chapter 173-226 WAC.)

The above table does provide an estimate of annual permit fee costs, even though these too may (in most cases) be no greater than incurred under existing conditions. The permit fee schedule proposed in WAC 173-308-320 is based on "residential equivalent values," thus helping to insure proportionality in impacts upon small versus large businesses. Fee rates vary depending upon the type of facility and activity involved. For this portion of the analysis, the appropriate rate is $0.162 per residential equivalent unit (defined, for septage haulers, as 1,250 gallons of septage). The schedule also exempts facilities with residential equivalent values of 300 or less from fee payments. Thus, as shown above, the smallest septic tank cleaning and septage hauling firms (as characterized in the RIA) would incur no costs on this account.

impacts on private treatment works: Privately-owned wastewater treatment works and centralized septage collection facilities are generally small, compared to publicly owned treatment works. Private treatment works are often operated by residential development associations, resorts and similar facilities in locations remote from convenient access to municipal treatment works but constrained from use of septic tanks, or as contract service providers to smaller communities. They usually treat only domestic wastewater and septage flows at a flow rate of one million gallons per day or less. The EPA RIA estimates that such facilities (that land apply) would be able to comply with 40 CFR 503 at a cost of less than five hundred dollars per year. An additional state requirement for (probable) annual reports cost burden of such reporting would be less than twenty dollars per year.

Privately-owned treatment works would also come under the proposed state permit and permit fee system. Again, it is assumed for this analysis that such facilities are presently operating under local permit and fee requirements, and that the costs involved in obtaining a state permit would be no greater than those now incurred. (Indeed, they may be less if a five year state permit can be substituted for an annual local permit, as noted above for septic tank cleaning firms.) Annual permit fees for such facilities would vary depending on the "residential equivalent value" appropriate to each. Currently available information does not permit more precise estimates. However, the size of the business and the number of residential equivalent units served should be directly correlated, implying that the impacts of these fees should not fall disproportionately upon small versus larger facilities. As with septic tank cleaning and septage hauling firms, it is expected that many smaller private treatment works and/or septage collection facilities would fall under the 300 residential equivalent units fee exemption.

impacts upon compost producers: The proposed state rule's impacts under this heading flow from WAC 173-308-260 and the corresponding federal rule language at 40 CFR 503.14(e), both dealing with biosolids sold or given away in a bag or other container (e.g., a pickup truck load). This may apply to treated sewage sludge given away by a municipal treatment works, or to compost or other products in which biosolids are a constituent ingredient. The federal rule requires that labelling or information sheets be provided to recipients of such material when it does not meet standards for what the proposed state rule calls "exceptional quality" biosolids. The label is to provide general instructions about proper use and application rates designed to insure that the receiving environment does not receive excess loading of any regulated pollutants that may be present.

The proposed state rule also contains a label/information sheet requirement, differing from the federal rule only in [that] the specific contents are more explicitly defined in terms of information to be conveyed. However, the proposed state rule language in WAC 173-308-260(4) applies this requirement to all biosolids or other products prepared or derived from biosolids not meeting "exceptional quality" standards (see WAC 173-308-080 for definition of exceptional quality biosolids). Products that are derived from biosolids already meeting the "exceptional quality" standard are exempt from labelling requirements.

Since most composting or similar processing activities convert nonexceptional quality biosolids to the more stringent standard through blending or further processing, the proposed state requirement should not extend much below the first transfer level. In any case, information sheets can be drafted and copied for pennies per copy. Hence, this state deviation from the strict wording of the federal rule is judged to have minor impact.

other costs - signs: Both the federal and the proposed state rule impose site management, use and access restriction requirements on sites where biosolids or domestic septage are land applied. The federal rule suggests that signs, among other things, may be appropriate as site access controls, but does not require them.

The proposed state rule does require signs as a site management/access measure, with the information to be included specified (see WAC 173-308-275). The costs associated with this requirement are deemed to be minimal. Again, drafting and copying a paper sign with the required information (even including plastic covering for weather protection) involves an expenditure of pennies per copy. Additionally, the proposed state rule allows for use of standard "No Trespassing" signs, with regulatory authority approval. Since the number of signs required is related directly to the size and number of sites involved, and since this would be expected to correlate directly with the size of the business involved, this impact would be unlikely to disproportionately affect small vs. large businesses. In addition, the proposed state rules provides for exemption from the signing requirement in cases where this is appropriate.

impacts on revenues/profits: As noted above, the impacts of the proposed state rule on private sector businesses' revenues or profits should be, for the most part, neutral or minimal. The exception might be the estimated capital and operating costs of complying with the screening/grinding requirement for septic tank cleaning firms that land apply. Since cleaning septic tanks is not really an option, it is assumed that affected firms will be able to pass these costs along to their customers.

mitigation: Since the impacts upon small versus large businesses estimated and shown here are not disproportionate, mitigation is not strictly required. However, the proposed state rule does have mitigative elements; many of which have been noted above. These include elimination of the permit fee requirement for firms serving 300 residential equivalent units or fewer, the elimination of label/information sheet requirements for certain biosolids-derived products as noted above, and the allowance for use of standard No Trespassing signs as a site access control measure. In addition, the proposed state permitting system (whether under a general permit or an individual facility permit) allows for tailoring of permit compliance requirements to individual operation or site conditions. If appropriate, these may be less stringent than the initial terms and conditions set down in the proposed rule.

[]

NEW SECTION

WAC 173-308-070 Use of term, "biosolids"--Explanation. Biosolids is a term adopted in state statute to distinguish municipal sewage sludge that is suitable for land application from that which is not. Under state law biosolids includes both municipal sewage sludge and septage that meet applicable criteria. Federal rules do not use the term "biosolids," and rely instead on the term "sewage sludge," which under the federal system includes domestic septage. Some federal guidance documents do use the term biosolids. Unless the context requires otherwise, biosolids is the term used in this chapter to refer to municipal sewage sludge or septage that has been or is being treated to meet standards so that it can be applied to the land. Material that will be disposed in a landfill is considered municipal sewage sludge. When the term septage is used, the reference is exclusively to septage.

[]

NEW SECTION

WAC 173-308-080 Definitions. Unless the department determines that the context of the rule requires otherwise, the following definitions are applicable for the purposes of this chapter.

"Administrator" means the Administrator of the United States Environmental Protection Agency, or an authorized representative.

"Aerobic digestion" is the biochemical decomposition of organic matter in biosolids into carbon dioxide and water by microorganisms in the presence of air. Aerobic digestion does not include composting.

"Agricultural land" is land on which a food crop, feed crop, or fiber crop is grown. This includes range land and land used as pasture.

"Agronomic rate" is the whole biosolids application rate (dry weight basis) that will provide the amount of nitrogen required for optimum growth of vegetation, and that will not result in the violation of applicable standards or requirements for the protection of ground or surface water as established under chapter 90.48 RCW and related rules including chapters 173-200 and 173-201 WAC.

"Anaerobic digestion" is the biochemical decomposition of organic matter in biosolids into methane gas and carbon dioxide by microorganisms in the absence of air. Anaerobic digestion does not include composting.

"Annual pollutant loading rate" is the maximum amount of a pollutant that can be applied to a unit area of land during a three hundred sixty-five-day period.

"Annual whole biosolids application rate" is the maximum amount of biosolids (dry weight basis) that can be applied to a unit area of land during a three hundred sixty-five-day period.

"Apply biosolids or biosolids applied to the land" means the land application of biosolids for the purpose of beneficial use.

"Beneficial use facility" means a site or sites where biosolids are applied to the land for beneficial use, which has been permitted as a treatment works treating domestic sewage in accordance with the provisions of WAC 173-308-310, and that has been designated as a beneficial use facility through the permitting process.

"Beneficial use of biosolids" means the application of biosolids to the land for the purposes of improving soil characteristics including tilth, fertility, and stability and enhancing the growth of vegetation consistent with protecting human health and the environment.

"Biosolids" means municipal sewage sludge that is a primarily organic, semisolid product resulting from the wastewater treatment process, that can be beneficially recycled and meets all applicable requirements under this chapter. Biosolids includes a material derived from biosolids, and septic tank sludge, also known as septage, that can be beneficially recycled and meets all applicable requirements under this chapter. For the purposes of this rule, semisolid products include biosolids or products derived from biosolids ranging in character from mostly liquid to fully dried solids.

"Bulk biosolids" means biosolids that are not sold or given away in a bag or other container for application to the land.

"Ceiling concentration" means the maximum concentration of a pollutant in any biosolids sample, beyond which level the biosolids would be classified as municipal sewage sludge not suitable for application to the land. Ceiling concentrations are established in Table 1 of WAC 173-308-160.

"Class I biosolids management facility" is any publicly owned treatment works (POTW), as defined in 40 CFR 501.2, required to have an approved pretreatment program under 40 CFR 403.8(a) (including any POTW located in a state that has elected to assume local program responsibilities under 40 CFR 403.10(e)), and any treatment works treating domestic sewage, as defined in 40 CFR 122.2, classified as a Class I biosolids management facility by the EPA Regional Administrator, or in the case of approved state programs, the Regional Administrator in conjunction with the state director, because of the potential for its biosolids use or disposal practice to affect public health and the environment adversely.

"Clean Water Act" or "CWA" means the Clean Water Act or Federal Clean Water Act (FCWA) (formerly referred to as either the Federal Water Pollution Act or the Federal Water Pollution Control Act Amendments of 1972), Public Law 92-500, as amended by Public Law 95-217, Public Law 95-576, Public Law 96-483, Public Law 97-117, and Public Law 100-4.

"Cumulative pollutant loading rate" is the maximum amount of a pollutant that can be applied to an area of land from biosolids that exceed the pollutant concentration limits established in Table 3 of WAC 173-308-160.

"Density of microorganisms" is the number of microorganisms per unit mass of total solids (dry weight) in the biosolids.

"Department" means the Washington state department of ecology and, within the scope of its delegation, a local jurisdictional health department that has been delegated authority under WAC 173-308-050.

"Director" means the director of the department of ecology or his or her authorized representative.

NEW SECTION

WAC 173-308-160 Biosolids pollutant limits. This section sets pollutant concentration limits, and annual and cumulative pollutant loading rate limits for biosolids that are applied to the land.

(1) Table 1 of this section sets the maximum allowable concentration (ceiling limit) of pollutants in biosolids that are applied to the land.

Municipal sewage sludge that contains any pollutant listed in Table 1 of this section at a concentration greater than the allowable ceiling limit is not biosolids, is a solid waste, and may not be applied to the land.

(2) Table 2 of this section sets the maximum quantities of pollutants that may be added to an area of land, also referred to as the cumulative pollutant loading rate. The cumulative pollutant loading rates in Table 2 apply when the concentration of any pollutant in biosolids that are applied to the land exceeds the allowable pollutant concentration limit in Table 3 of this section.

(a) No person may apply bulk biosolids subject to the cumulative pollutant loading rates in Table 2 of this section to a land application site, if any of those rates have been reached on the site.

(b) Before bulk biosolids subject to the cumulative pollutant loading rates in Table 2 of this section are applied to the land, the person who proposes to apply the bulk biosolids must contact the local health department and the department to determine whether bulk biosolids subject to the cumulative pollutant loading rates were applied to the site before the effective date of this chapter.

(i) If bulk biosolids subject to the cumulative pollutant loading rates in Table 2 of this section have been applied to the site since July 20, 1993, and the cumulative amount of each pollutant applied to the site since that date is known, in addition to any amount subtracted in (b)(iii) of this subsection, the amount previously applied must be subtracted from the cumulative pollutant loading rate for each pollutant, to determine the remaining amount of pollutant that may be applied to the site.

(ii) If bulk biosolids subject to the cumulative pollutant loading rates in Table 2 of this section have been applied to the site since July 20, 1993, and the cumulative amount of each pollutant applied to the site in the bulk biosolids since that date is not known, additional biosolids subject to the cumulative pollutant loading rates in Table 2 of this section may not be applied to the site.

(iii) If bulk biosolids were applied to the site prior to July 20, 1993, and the cumulative amount of each pollutant applied to the site prior to that date can be determined, in addition to any amount subtracted in (b)(i) of this subsection, the amount applied must be subtracted from the cumulative pollutant loading rate for each pollutant, to determine the remaining amount of pollutant that may be applied to the site.

(iv) If bulk biosolids subject to the cumulative pollutant loading rates in Table 2 of this section have not been applied to the site, the cumulative amount of each pollutant listed in Table 2 of this section may be applied to the site.

(v) Any person who applies bulk biosolids to the land, which are subject to the cumulative pollutant loading rates in Table 2 of this section, must provide written notice prior to the initial application of bulk biosolids to the land. Notice must be submitted to the department, and to any local health department in whose jurisdiction the biosolids will be applied. The department and the local health department must retain and provide access to the notice. The notice must include:

(A) The location, by street address if applicable, a copy of the assessor's plat map(s) with the application area(s) clearly shown or the latitude and longitude of the approximate center of each land application site, and the section, township and range of each quarter section on which biosolids are applied.

(B) The name, address, telephone number, and National Pollutant Discharge Elimination System or state waste discharge permit number and state biosolids permit number (if applicable) of the person who prepared the biosolids and also of the person who applies (if applicable) the bulk biosolids.

(3) Table 3 of this section sets a lower pollutant concentration threshold which, when achieved, relieves the person who prepares biosolids and the person who applies biosolids, from certain requirements related to recordkeeping, reporting, and labeling.

(4) Table 4 of this section sets annual pollutant loading rates used to derive an annual whole biosolids application rate. Table 4 is applicable only when biosolids that are sold or given away in a bag or other container for application to the land exceed any of the pollutant concentration limits in Table 3 of this section. The person who prepares the biosolids must provide information on compliance with this requirement on a label or information sheet as required under WAC 173-308-260 (1)(b)(ii) and (4)(b).

(b) Causes for modification. The following are causes for modification but not revocation and reissuance of individual permits or authorization of coverage under a general permit except when the permittee requests or agrees.

(i) Alterations. There are material and substantial alterations or additions to the permitted facility or activity that occurred after permit issuance that justify the application of permit conditions that are different from or absent in the existing permit.

(ii) Information. The department has received new information. Individual permits or authorization of coverage under a general permit may be modified during their terms for this cause only if the information was not available at the time of permit issuance (other than revised regulations, guidance, or test methods) and would have justified the application of different permit conditions at the time of issuance.

(iii) New regulations. New regulations have been adopted or the standards or regulations on which the permit was based have been changed by adoption of amended standards or regulations or by judicial decision after the permit was issued.

(iv) Compliance schedules. The department determines good cause exists for modification of a compliance schedule, such as an act of God, strike, flood, or materials shortage or other events over which the permittee has little or no control and for which there is no reasonable available remedy. However, in no case may a compliance schedule be modified to extend beyond an applicable Clean Water Act statutory deadline.

(v) Land application plans. When required by a permit condition to incorporate a general land application plan for beneficial use of biosolids, to revise a general land application plan, or to add a general land application plan.

(c) The following are causes to modify or alternatively, revoke and reissue, an individual permit or the conditions for coverage under a general permit.

(i) Cause exists for termination under subsection (22) of this section and the department determines that modification or revocation and reissuance is appropriate.

(ii) The department has received notification of a proposed transfer of the permit.

(d) When an individual permit or coverage under a general permit is modified or revoked and reissued, the public notice requirements of subsection (11) of this section, and if required the public hearing requirements of subsection (12) of this section must be complied with for the reopened conditions or reissued permit.

(22) Termination of permits. The following are causes for terminating an individual permit or coverage under a general permit during its term, or for denying a permit renewal application:

(a) Noncompliance by the permittee with any condition of the permit;

(b) The permittee's failure in the application or during the permit issuance process to disclose fully all relevant facts, or the permittee's misrepresentation of any relevant facts at any time;

(c) A determination that the permitted activity endangers human health or the environment and can only be regulated to acceptable levels by permit modification or termination; or

(d) A change in any condition that requires either a temporary or a permanent reduction or elimination of any activity controlled by the permit.

(23) Enforcement. Any violation of this chapter or any permit issued under this chapter, may be subject to the enforcement provisions of applicable law, including chapters 70.95 and 70.95J RCW.

(24) Appeals. Any person aggrieved by a decision of the department made in accordance with provisions of this chapter may appeal that decision only as provided by applicable law, including chapters 43.21B RCW and 34.05 RCW.

NEW SECTION

WAC 173-308-320 Permit fees. (1) All treatment works treating domestic sewage that are required to obtain a permit under this section must pay an annual biosolids permit fee to the department of ecology.

(2) Biosolids permit fees are assessed prospectively on an annual basis and apply regardless of the date of issuance of a permit.

(3) Biosolids permit fees are assessed and collected for fiscal years and are due and payable within forty-five days after the department mails a billing statement.

(a) Failure to pay a permit fee is cause for revocation of permit coverage.

(b) The department may at its discretion mail partial billing statements two or more times per year, in which case a treatment works is responsible only for the amount reflected on the current (and any past due) billing statement.

(c) Receiving-only facilities, centralized septage treatment facilities, and persons who apply septage to the land that determine a residential equivalent value under subsection (4)(b) or (c) of this section may submit periodic partial payments based on their estimated residential equivalent value, provided that the requirements of subsection (4)(b)(ii) and (iii) and (c)(ii) and (iii) of this section are met.

(4) The permit fee schedule is based on the number of residences or residential equivalents (residential equivalent value) contributing to a permittee's biosolids management system, and incorporates the annual fiscal growth factor calculated under chapter 43.135 RCW.

(a) For facilities with NPDES permits issued under chapter 173-220 WAC or state waste discharge permits issued under chapter 173-216 WAC, the department will use residential equivalent values determined under chapter 173-224 WAC.

(b) The residential equivalent value for receiving-only facilities other than septage facilities in (c) of this subsection is the sum of the fraction of residential equivalent values contributed from all sources, as determined by considering the portion of the current annual biosolids production of each originating source that is provided to the receiving facility.

(i) A receiving-only facility must determine a residential equivalent value based on projected capacity as detailed in the permit application submitted under this section and the method described in (b) of this subsection.

(ii) A receiving-only facility may not accept any amount of biosolids in excess of the residential equivalent value for which they have paid a fee.

(iii) A receiving-only facility may increase its capacity to accept biosolids by submitting an appropriate additional permit fee accompanied by a letter of explanation, but in no case may a facility exceed an allowed capacity established as a permit condition under this section.

(c) For centralized septage treatment facilities and persons who apply septage to the land, 1,250 gallons of septage received for treatment or applied to the land is equal to one residential equivalent as shown in Equation (4).



[Open Style:Columns Off]

(WAC 173-308-320, Equation (4))






(i) A centralized septage treatment facility and a person who applies septage to the land must determine a residential equivalent value based on projected capacity as detailed in the permit application submitted under this section and the method described in (c) of this subsection.

(ii) A centralized septage treatment facility or a person who applies septage to the land may not accept any amount of septage in excess of the residential equivalent value for which they have paid a fee.

(iii) A centralized septage treatment facility or a person who applies septage to the land may increase its capacity to accept septage by submitting an appropriate additional permit fee accompanied by a letter of explanation, but in no case may a facility exceed an allowed capacity established as a permit condition under WAC 173-308-310.

(d) Equation (5) below is used to calculate permit fees:



(WAC 173-308-320, Equation (5))






(i) REV = residential equivalent value.

(ii) FGF = An annual fiscal growth factor expressed as a percentage, as determined under chapter 43.135 RCW.

(iii) Cost per REFGF = cost per residential equivalent in dollars including a fiscal growth factor. The Cost per REFGF is obtained by multiplying the cost per residential equivalent in the preceding year by the current year's fiscal growth factor as follows in (6):



(WAC 173-308-320, Equation (6))


[Open Style:Columns On]





For implementation of the fiscal growth factor, the base year for all biosolids permit fees will be fiscal year 1998, ending June 30, 1998. In the base year, the FGF will be zero.

(e) Unless a lower cost is specified in a permit, the cost per residential equivalent in the base year will be as follows:

(i) $0.00 per residential equivalent for any permit for any facility with a total residential equivalent value of less than 300, including those that would otherwise fall under (e)(ii) through (v) of this subsection.

(ii) $0.015 per residential equivalent for a permit authorizing municipalities that own or operate incinerators that fire municipal sewage sludge to dispose of municipal sewage sludge generated by their own treatment works in a municipal solid waste landfill or through another treatment works treating domestic sewage on an emergency basis.

(iii) $.20 per residential equivalent for permits authorizing disposal in a municipal solid waste landfill, except for facilities under (e)(ii) of this subsection.

(iv) $0.04 per residential equivalent for permits issued to receiving-only facilities as defined in WAC 173-308-080.

(v) $0.162 per residential equivalent for permits authorizing any other type of biosolids management activity, including but not limited to the following:

(A) Direct beneficial use by a treatment works treating domestic sewage;

(B) Discharge by one treatment works to another treatment works, including delivery of biosolids to an incinerator from nonincinerating jurisdictions;

(C) Prolonged treatment or storage, including lagoon systems;

NEW SECTION

WAC 173-308-900 Appendix A--Procedure to determine the annual whole biosolids application rate. When biosolids are sold or given away in a bag or other container for application to the land, and any of the pollutant concentration limits in Table 3 of WAC 173-308-160 are exceeded, the mathematical product of the concentration in the biosolids of each pollutant listed in Table 4 of WAC 173-308-160 and the annual whole biosolids application rate (AWBAR) must not cause the annual pollutant loading rate for the pollutant in Table 4 of WAC 173-308-160 to be exceeded. This appendix contains the procedure used to determine an AWBAR that does not cause the annual pollutant loading rates in Table 4 of WAC 173-308-160 to be exceeded. The relationship between the annual pollutant loading rate (APLR) for a pollutant and the annual whole biosolids application rate (AWBAR) is shown in equation (7).



[Open Style:Columns Off]

(WAC 173-308-900, Equation (7))






Where:

APLR = Annual pollutant loading rate in kilograms per hectare per 365 day period.

C = Pollutant concentration in milligrams, per kilogram of total solids (dry weight basis).

AWBAR = Annual whole biosolids application rate in metric tons per hectare per 365 day period (dry weight basis).

0.001 = A conversion factor.

To determine the AWBAR, equation (7) is rearranged into equation (8):



(WAC 173-308-900, Equation (8))


[Open Style:Columns On]





The procedure used to determine the AWBAR is presented below.

Procedure:

1. Analyze a sample of the biosolids to determine the concentration for each of the pollutants listed in Table 4 of WAC 173-308-160.

2. Using the pollutant concentrations from Step 1 and the APLRs from Table 4 of WAC 173-308-160, calculate an AWBAR for each pollutant using equation (8).

3. The correct AWBAR is the lowest AWBAR calculated in Step 2.
