(2) Municipal sewage sludge or septage that fails to meet standards for classification as biosolids is a solid waste, and may not be applied to the land.

(3) Municipal sewage sludge or septage that will be disposed in a landfill is a solid waste.

[]

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.

"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.

Generally, emergency situations requiring the use of disposal facilities will normally occur as a result of inclement weather conditions at a beneficial use site, contractual or technical difficulties in the treatment, transportation, or application of the biosolids, or as a result of short term economic or administrative barriers, any and all of which are expected to be resolved within a period of one year.

"Disposal on a long-term basis" means to adopt disposal as a preferred method of management for at least five years, or for an indefinite period of time with no expectation for pursuing other management alternatives.

"Disposal on a temporary basis" means a period of more than one but less than five years. Generally, situations requiring the temporary use of disposal facilities will normally occur as a result of deficiencies in the wastewater or biosolids treatment process, or economic, administrative, or contractual constraints which cannot be resolved in less than one year.

"Domestic septage" means domestic septage - Class I, Class II, or Class III as defined in this section.

"Domestic septage - Class I" is liquid or solid material removed from domestic septic tanks, cess pools, or similar treatment works that receive only domestic sewage, and that has had a sufficiently long residency time to be considered largely stabilized. For the purposes of managing mixed loads or batches of septage, a load or batch is considered Class I if it does not exceed twenty-five percent by volume of Class II domestic septage or twenty-five percent by volume of restaurant grease trap waste, unless otherwise approved by the regulatory authority.

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) A person may not 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; and

(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).

(i) Facilities applicable under (c) of this subsection that have submitted a notice of intent to be covered or have been notified that they are covered under a general permit, and those that have applied for coverage under a general permit, are provisionally approved for coverage under an applicable general permit to apply biosolids to existing sites as permitted by the local health department and in accordance with the requirements of the applicable general permit and this chapter.

(ii) A beneficial use facility may not obtain provisional approval for coverage under a general permit, but may obtain provisional approval for existing land application sites after being permitted as a beneficial use facility.

(d) Except for provisionally approved facilities under this subitem (d), a facility may not engage in new biosolids management practices or implement significant changes to biosolids management practices at existing sites, or apply biosolids to new or expanded sites until all applicable requirements of this section including those for public notice, and public hearings or meetings, have been satisfied.

Facilities that have submitted a notice of intent or that have been notified of coverage under a general permit, or that have applied for coverage under a general permit, are provisionally approved for coverage under an applicable general permit to apply biosolids to sites consistent with the applicable requirements of this chapter and the applicable general permit and as approved by the local health department, if the public notice requirements under subsection (11) of this section have been fulfilled, and no request for a public hearing has been made or the department has denied the request, and all comments received have been resolved to the satisfaction of the local health department;

(e) Facilities with provisional approval are subject to further review and permitting requirements at a later date, and are subject at all times to all applicable conditions of this chapter and the applicable general permit.

(f) In no case may a lack of action by the department be construed as relieving an applicant of the obligation to comply with any of the provisions of this chapter or an applicable general permit, or as approving final use or disposal practices that are not consistent with the provisions of this chapter or an applicable general permit, or that pose a threat to human health or the environment.

(18) Prohibition. The department may not issue a permit when the Regional Administrator of EPA has objected in writing under 40 CFR 123.44.

(19) Duration of permits.

(a) Permits are issued for fixed terms, up to but not exceeding five years from the effective date of the permit.

(i) Coverage under a general permit may be issued for a period up to the remaining term of issuance for the permit.

(b) The term of a permit may not be extended by modification beyond five years.

(20) Transfer of permit coverage.

(a) Except as provided in (b) of this subsection, a permit may be transferred by the permittee to a new owner operator only if the permit has been modified or revoked and reissued to identify the new permittee and incorporate other requirements as may be necessary to assure compliance with the requirements of this chapter.

(b) Coverage under a permit is automatically transferred from the old permittee to a new permittee, on the date agreed to, if:

(i) A written, signed agreement, between the old and new permittees containing a specific date for transfer of permit responsibility, coverage, and liability is submitted in accordance with the requirements of subsection (7) of this section at least thirty days in advance of the proposed date of transfer; and

(ii) The department has not notified both permittees of any objection to the transfer, or of the intent to revoke coverage under the general permit.

(c) No condition or requirement of a permit or this chapter may be waived by the transfer of permit coverage from one party to another.

(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 facilities 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 denial of coverage under a permit or revocation of existing coverage. Fees are considered delinquent if they are not received by the first invoice billing due date. Permit holders will be notified by certified letter and have thirty days to bring their account up-to-date before further action is taken by the department.

(b) The department may at its discretion mail partial billing statements two or more times per year, in which case a facility 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 payments as provided in (c)(i), (ii), and (iii) of this subsection, based on the actual level of service, provided that they submit a letter to the department indicating their intent to do so.

(i) Facilities under (c) of this subsection must submit a quarterly payment and statement of actual service level within ten days of the end of each quarter (not later than the 10th day of March, June, September, and December of each year), except as provided in (c)(ii) or (iii) of this subsection.

(ii) Facilities under (c) of this subsection that estimate and provide a level of service less than three hundred residential equivalents per year are subject to a fee of $0.00 per residential equivalent and are not required to submit periodic payments, but must submit a statement of actual service level at least once per year.

(iii) Facilities under (c) of this subsection that calculate an annual residential equivalent value equal to or greater than three hundred residential equivalents per year may withhold a payment for any quarter where the total amount due is less than fifty dollars, provided a statement of the actual service level is submitted and that all accounts are brought up-to-date by July 10th of each year.

(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.

A receiving-only facility must determine an estimated residential equivalent value based on projected capacity as detailed in the permit application submitted under WAC 173-308-310 and the method described in (b) of this subsection.

(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]

A centralized septage treatment facility and a person who applies septage to the land must determine an estimated residential equivalent value based on projected capacity as detailed in the permit application submitted under WAC 173-308-310 and the method described in (c) of this subsection.

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

(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 RE_FGF = cost per residential equivalent in dollars including a fiscal growth factor. The Cost per RE_FGF 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):

[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 facility in a municipal solid waste landfill or through another facility 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) Transfer from one facility to another facility, including delivery of biosolids to an incinerator from nonincinerating jurisdictions;

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

(D) Treatment or land application of septage.

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]

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):

[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.
