Article I. General Provisions

13.14.010 Purpose and policy.

The regulations in this chapter (pretreatment regulations) set forth uniform requirements for users of publicly owned treatment works (POTW) for the Sumner Wastewater Treatment Facility (WWTF) and contributing jurisdictions (contributing jurisdictions) to comply with all applicable state and federal laws, including Chapter 173-216 WAC, the Clean Water Act (33 United States Code, Section 1251 et seq.), and the General Pretreatment Regulations (40 Code of Federal Regulations Part 403). These pretreatment regulations are consistent with the Sumner-Bonney Lake Joint Pretreatment Program Pretreatment Regulations and are adopted in accordance with the interlocal agreement between the cities of Bonney Lake and Sumner for the coordination of cooperative wastewater services, dated January 23, 2024.

The objectives of this chapter are:

A. To encourage economic growth by establishing clear, fair standards and requirements for the management and pretreatment of nondomestic waste.

B. To protect the POTW from potential harm. Harm to be prevented includes causing interference or otherwise harming the POTW; causing pass through, or otherwise harming the receiving environment; or causing the POTW to respond to discharge based on a real or perceived threat;

C. To protect POTW staff who may be affected by wastewater and sludge in the course of their employment and to protect general public;

D. To promote reuse and recycling of industrial wastewater by industrial users;

E. To provide high-quality end products, such as reclaimed water and biosolids from the POTW, for beneficial use;

F. To provide for fees for the equitable distribution of the cost of operations, maintenance, and improvement of the POTW, as economically feasible; and

G. To enable the Sumner WWTF to comply with its National Pollution Discharge Elimination System (NPDES) permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the POTW is subject.

This chapter shall apply to all persons connected (or believed connected) to the POTW. The pretreatment regulations compel the production of information; authorize the issuance of control documents, including wastewater discharge permits; provide for monitoring, compliance, and enforcement activities; establish administrative review procedures; require reporting; and provide for the setting of fees for the equitable distribution of costs resulting from the program establishment herein.

The provisions of this chapter shall be revised or amended from time to time, consistent with the purpose and policy set forth within this chapter, to conform to changes in the state and federal water quality laws and regulations. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.020 Administration.

Except as otherwise provided in this chapter, as the owner of the Sumner Wastewater Treatment Facility (WWTF), the city of Sumner (Sumner) is the control authority responsible for administering and managing the overall affairs of the WWTF. The city of Bonney Lake (city) is the owner of a system of sewers that provide for the collection and transmission of wastewater to the WWTF. The city is the contributing jurisdiction (contributing jurisdiction) responsible for managing their system of sewers connected to the WWTF.

Pursuant to the interlocal agreement between the cities of Bonney Lake and Sumner for the coordination of cooperative wastewater services, dated January 23, 2024:

A. The city designates Sumner as the city’s agent for purposes of implementing and enforcing this chapter for nondomestic users within the city’s service area;

B. Sumner will handle technical and administrative duties, inspections, enforcement and emergency actions under this chapter; and

C. Sumner, as the city’s agent, shall perform technical and administrative duties to implement and enforce this chapter, including issuing permits to nondomestic users, conducting inspections, sampling and analysis, taking enforcement actions, including actions in superior court; and

D. Performing other technical and administrative duties that the city and Sumner deem necessary and appropriate.

Consistent with the city’s delegation of authority to Sumner, as described above, the Sumner public works director shall have authority to administer, implement, and enforce the provisions of this chapter, to the extent allowed by law. Any reference to the “director” in this chapter shall mean the Sumner public works director, unless the term is otherwise defined for purposes of a specific provision. See definition of “director” in BLMC 13.14.210. Any powers granted to, or duties imposed upon, the director may be delegated by the director to other control authority, WWTF or contributing jurisdiction personnel.

New Source.

1. Any building, structure, facility, or installation from which there is (or may be) a discharge of pollutants, the construction of which commenced after the publication of proposed categorical pretreatment standards under Section 307(c) of the Act, which will be applicable to such source if such standards are thereafter promulgated in accordance with that section; provided, that:

a. The building, structure, facility, or installation is constructed at a site at which no other source is located;

b. The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or

c. The production or wastewater generating processes of the building, structure, facility, or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source, should be considered.

2. Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of subsection (1)(a) or (1)(c) of this definition but otherwise alters, replaces, or adds to existing process or production equipment.

3. Construction of a new source as defined under this subsection has commenced if the owner or operator has:

a. Begun, or caused to begin, as part of a continuous onsite construction program:

i. Any placement, assembly, or installation of facilities or equipment; or

1. Except as provided in subsection (2) of this definition, a significant industrial user is:

a. A nondomestic user subject to categorical pretreatment standards; or

b. A nondomestic user that:

i. Discharges an average of 25,000 gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling, and boiler blowdown wastewater);

ii. Contributes a process wastestream which makes up five percent or more of the average dry weather hydraulic or organic capacity of the treatment plant; or

iii. Is designated as such by the director, on the basis that it has a reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement.

2. Upon a finding that a nondomestic user meeting the above criteria for a significant industrial user is not a categorical industrial user, or is a nondischarging categorical industrial user, and has no reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement, the director may at any time, on its own initiative or in response to a petition received from a nondomestic user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such nondomestic user should not be considered a significant industrial user.

Significant Noncompliance. The term “significant noncompliance” means:

1. Any violation of a pretreatment standard or requirement including numerical limits, narrative standards, and prohibitions, that the director or the city determines has caused, alone or in combination with other discharges, interference or pass through, including endangering the health of POTW personnel or the general public.

2. Any discharge that has caused imminent endangerment to the public or to the environment or has resulted in the director’s or the city’s exercise of its emergency authority to halt or prevent such a discharge.

3. Any violation(s), including of best management practices, which the director or the city determines will adversely affect the operation or implementation of the local pretreatment program.

4. Chronic violations of wastewater discharge limits, defined here as those in which 66 percent or more of all of the measurements taken for the same pollutant parameter taken during a rolling six-month period exceed, by any magnitude, a numeric pretreatment standard or requirement, including instantaneous limits of BLMC 13.14.330.

5. Technical review criteria (TRC) violations, defined here as those in which 33 percent or more of wastewater measurements taken for each pollutant parameter during a rolling six-month period equal or exceed the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined by BLMC 13.14.330, multiplied by the applicable criteria. Applicable criteria are 1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH.

6. Failure to meet, within 90 days of the scheduled date, a compliance schedule milestone contained in a wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance.

7. Failure to provide any required report within 45 days after the due date. This includes initial and periodic monitoring reports, and reports on initial compliance and on meeting compliance schedules.

8. Failure to accurately report noncompliance.

For purposes of this definition, the term “director” means the Sumner public works director or the Bonney Lake public services director.

Slug Load or Slug Discharge. Any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or a noncustomary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW’s regulations, local limits or permit conditions.

13.14.310 National categorical pretreatment standards.

The categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405-471 are hereby incorporated by reference.

A. Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the director may impose equivalent concentration or mass limits in accordance with subsections (E) and (F) of this section and 40 CFR Part 403.6(c).

B. Upon promulgation of a federal categorical pretreatment standards for a particular industrial subcategory, the federal standard, if more stringent, shall supersede the local limit imposed in this chapter. If the local limit imposed in this chapter is more stringent than the federal standard, then the local limit shall supersede the federal limit.

C. When categorical pretreatment standards are expressed in terms of a mass of pollutant which may be discharged per unit of production, the director may either impose limits based on mass or equivalent effluent concentrations. The nondomestic user must supply appropriate actual or projected long-term production rates for the unit of production specified in order to facilitate this process pursuant to 40 Part CFR 403.6(c)(2).

D. The director may allow wastewater subject to a categorical pretreatment standard to be mixed with other wastewaters prior to treatment. In such cases, the nondomestic user shall identify all categorical wastestreams and provide sufficient information on each noncategorical wastestream to determine whether it should be considered dilute for each pollutant. Absent information showing that noncategorical wastestreams contain the pollutant in question at levels above that of the supply water, such wastestreams shall be considered dilute. In such situations, the director shall apply the combined wastestream formula as found at 40 CFR Part 403.6(e) to determine appropriate limits.

E. When a categorical pretreatment standard is expressed only in terms of pollutant concentrations, a nondomestic user may request that the limits be converted to equivalent mass limits. The director may establish equivalent mass limits if the nondomestic user meets all of the conditions set forth below.

1. To be eligible for equivalent mass limits, the nondomestic user must submit information with its permit application or permit modification request which:

a. Shows it has a pretreatment system which has consistently met all applicable pretreatment standards and is maintained compliance without using dilution;

b. Describes the water conserving practices and technologies it employs, or will employ, to substantially reduce water use during the term of its permit;

c. Includes the facility’s actual average daily flow rate for all wastestreams from continuous effluent flow metering;

d. Determines an appropriate unit of production, and provides the present and long-term average production rates for this unit of production;

e. Shows that long-term average flow and production are representative of current operating conditions;

f. Shows that its daily flow rates, production levels, or pollutant levels do not vary so much that equivalent mass limits would be inappropriate; and

g. Shows the daily and monthly average pollutant allocations currently provided based on the proposed unit of production.

2. A nondomestic user subject to equivalent mass limits must:

a. Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits;

b. Continue to record the facility’s flow by continuous effluent flow monitoring;

c. Continue to record the facility’s production rates;

d. Notify the director if production rates are expected to vary by more than 20 percent from the baseline production rates submitted according to subsection (E)(1)(d) of this section. The director may reassess and revise equivalent limits as necessary to reflect changed conditions; and

e. Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to subsection (E)(1)(b) of this section so long as it discharges under an equivalent mass limit.

3. Equivalent mass limits:

a. Will not exceed the product of the actual average daily flow from regulated process(es) of the nondomestic user and the applicable concentration-based daily maximum and monthly average standards (and the appropriate unit conversion factor);

b. May be reassessed and the permit revised upon notification of a revised production rate, as necessary to reflect changed conditions at the facility; and

c. May be retained in subsequent permits if the nondomestic users’ production basis and other information submitted in subsection (E)(1) of this section is verified in their reapplication. The nondomestic user must also be in compliance with BLMC 13.14.1420 regarding the prohibition of bypass.

F. The director may convert the mass limits of the categorical pretreatment standards of 40 CFR Parts 414 (organic chemicals), 419 (petroleum refining), and 455 (pesticide formulating, packaging, and repackaging) to concentration limits in permits for such nondomestic users. In such cases, the director will document the basis and the determination that dilution is not being substituted for treatment in the permit fact sheet.

G. The control authority is obliged under federal regulations to make the documentation of how any equivalent limits were derived (concentration to mass limits or vice versa) publicly available.

H. Once incorporated into its permit, the nondomestic user must comply with the equivalent limits in lieu of the categorical pretreatment standards from which they were derived.

I. The same production and flow estimates shall be used in calculating equivalent limits for the monthly (or multiple day average) and the maximum day.

J. Nondomestic users subject to permits with equivalent mass or concentration limits calculated from a production-based standard shall notify the director if production will significantly change. This notification is required within two business days after the nondomestic user has a reasonable basis to know that production will significantly change in the next calendar month. Nondomestic users who fail to notify the director of such anticipated changes must meet the more stringent of the equivalent limits or the nondomestic user’s prior limits. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.320 State pretreatment standards.

State pretreatment standards and requirements, located at Chapter 173-216 WAC, were developed under authority of the state Water Pollution Control Act, Chapter 90.48 RCW and are hereby incorporated by reference. The version incorporated is the version current as of the date of the latest revision or version of this chapter. All waste materials discharged from a commercial or industrial operation into the POTW must satisfy the provisions of Chapter 173-216 WAC. In addition to more stringent prohibitions, the provisions described in subsections (A) through (J) of this section are unique to the state and are required by this chapter for discharges to a POTW.

A. Any person who constructs or modifies or proposes to construct or modify wastewater treatment facilities must first comply with the regulations for submission of plans and reports for construction of wastewater facilities, Chapter 173-240 WAC. Nondomestic users shall request approval for such plans through the director. Prior to constructing or modifying wastewater treatment facilities, plans and reports as required by Chapter 173-240 WAC must be approved by the director.

B. Nondomestic users shall apply to the director for a permit at least 120 days prior to the intended discharge of any pollutants (BLMC 13.14.530) other than sewage or wastewater which the director has determined is similar in character and strength to normal domestic wastewater with no potential to adversely affect the POTW.

C. All significant industrial users must apply for and obtain a wastewater discharge permit prior to discharge.

D. All nondomestic users shall apply AKART to waste discharges to the waters of the state.

E. Discharge restrictions of Chapter 173-303 WAC (Dangerous Waste) shall apply to all domestic and nondomestic users. Specific written approval from the control authority and Ecology is required prior to the discharge of dangerous wastes.

F. Claims of confidentiality shall be submitted according to WAC 173-216-080. Information which may not be held confidential includes the: name and address of applicant, description of proposal, the proposed receiving water, receiving water quality, and effluent data. Claims shall be reviewed based on the standards of WAC 173-216-080, Chapter 42.56 RCW, Chapter 173-03 WAC, and RCW 43.21A.160.

G. Persons applying for a new permit or a permit renewal or modification which allows a new or increased pollutant loading shall publish notice for each application in the format provided by the director. Such notices shall fulfill the requirements of WAC 173-216-090. These requirements include publishing:

1. The name and address of the applicant and facility/activity to be permitted;

2. A brief description of the activities or operations which result in the discharge;

3. Whether any tentative determination has been reached with respect to allowing the discharge;

4. The address and phone number of the office of the director where persons can obtain additional information;

5. The dates of the comment period (which shall be at least 30 days); and

6. How and where to submit comments or have any other input into the permitting process, including requesting a public hearing.

H. The director may require the applicant to also mail this notice to persons who have expressed an interest in being notified, to state agencies and local governments with a regulatory interest, and to post the notice on the premises. If the director determines there is sufficient public interest the control authority or contributing jurisdiction, as appropriate, shall hold a public meeting following the rules of WAC 173-216-100. The director may assume responsibility for public notice requirements for any person and may waive this requirement for any nondomestic user not classified as a CIU, SIU, or MIU by the director.

I. Permit terms shall include, wherever applicable, the requirement to apply AKART.

J. All required monitoring data shall be analyzed by a laboratory registered or accredited under the provisions of Chapter 173-50 WAC, except for flow, temperature, settleable solids, conductivity, pH, turbidity, and internal process control parameters. However, if the laboratory analyzing samples for conductivity, pH, and turbidity must otherwise be accredited, it shall be accredited for these parameters as well. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.330 Local limits.

A. The control authority has established and may periodically modify local limits pursuant to 40 CFR Part 403.5(c) based upon the POTW’s site-specific flow and loading capacities, receiving water considerations, and reasonable treatment expectations for nondomestic wastewater using a method approved by the director, and the city has adopted those local limits in this chapter. In the event that the control authority modifies the local limits, the city shall modify the local limits adopted in this chapter.

B. Unless the city or the director determines that public health or safety require an earlier implementation, any modification the control authority or the city establishes to the local limits in Table 330-1 shall not go into effect until 30 days after reasonable notice of the changes have been provided to the public and persons known to the control authority or the city who may discharge wastewater containing analytes subject to such local limits.

C. The pollutant limits in Table 330-1 are established to protect against pass through and interference and reflect the application of reasonable treatment technology. No nondomestic user shall discharge wastewater in excess of the daily maximum limits shown in Table 330-1 unless authorized in writing by the director.

D. The local limits shown in Table 330-1 apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for total metal unless indicated otherwise. The director may impose mass limits in addition to, or in place of, concentration-based limits in accordance with BLMC 13.14.310.

E. Significant industrial users and categorical industrial users shall also be subject to instantaneous limits (as determined by a grab sample) equal to twice the daily maximum concentration limit identified in Table 330-1 for any pollutant for which a composite sample is required in a permit. This provision is not applicable to SIUs and CIUs without the permit requirement to collect a composite sample for the analyte in question.

G. A high strength user is any nondomestic user who, in any given month, discharges wastewater found to contain a monthly average of more than 50 pounds per day of biochemical oxygen demand and 50 pounds per day of total suspended solids. High strength users shall be subject to charges as determined by the director and as amended and under the authority of this chapter up to any maximum loading limit.

H. The control authority shall use the individual permit process to establish ceiling limits for compatible pollutants and appropriate discharge limits for all other pollutants not listed in this section. This includes pollutants subject to regulation under RCRA, volatile or semi-volatile organic compounds, halogenated or brominated compounds, poly-aromatic hydrocarbons, polymers, surfactants, pesticide active ingredients, PFOS/PFOA, 6PPD-quinone and any other pollutant identified by the control authority.

I. The director or the city may establish and require best management practices for any category of nondomestic user or type of industrial process which creates a nondomestic wastestream. Such requirements may be applied either in lieu of or in addition to the local limits in this section. BMPs may also include alternative limits which may be applied at the end of a specific process or treatment step instead of at the combined effluent.

J. Where a nondomestic user is subject to a categorical pretreatment standard and a local limit for a given pollutant, the more stringent provision shall control. (Ord. 1725 § 2, 2024; Ord. 1719 § 1 (Exh. A), 2024).

13.14.340 Right of revision.

The control authority and the city reserve the right to establish, by subsequent resolution or regulation, or in wastewater discharge permits or other control documents, more stringent standards, or requirements for any discharges to the POTW. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.350 Dilution.

No nondomestic user shall ever increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with a discharge limit unless expressly authorized by an applicable pretreatment standard or requirement. The director may impose mass limitations on nondomestic users where deemed appropriate to safeguard against the use of dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate. (Ord. 1719 § 1 (Exh. A), 2024).

Article IV. Pretreatment of Wastewater

13.14.400 Pretreatment facilities.

Nondomestic users shall provide wastewater pretreatment as necessary to comply with this chapter and shall achieve compliance with the pretreatment standards set out in this chapter within the time limitations specified by EPA, the state, or the control authority, whichever is more stringent. Any pretreatment facilities necessary for compliance shall be provided, operated, and maintained at the nondomestic user’s expense, and satisfy state requirements for review and approval of plans for wastewater facilities as described in BLMC 13.14.320. Such plans (engineering report, plans and specifications, and operation and maintenance manuals) shall be submitted (as required by Chapter 173-240 WAC) to the director for review and approval prior to construction. The review of such plans and operating procedures shall in no way relieve the nondomestic user from the responsibility of modifying such pretreatment facilities as necessary to produce a discharge acceptable to the director under the provisions of this chapter. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.410 Additional pretreatment measures.

A. The director or the city may immediately and effectively halt or prevent any discharge of pollutants to the POTW which reasonably appear to present an imminent endangerment to the health or welfare of POTW staff or general public. In such cases, the director or the city will provide the user advance notice if possible but shall not delay a response to imminent endangerment.

B. The director or the city may halt or prevent any discharge to the POTW which presents or may present an endangerment to the environment, or which threatens to interfere with the operation of the POTW. In such cases, the director or the city shall attempt to provide not only notice to the affected nondomestic user(s), but the opportunity to respond.

C. Any nondomestic user causing the director or the city to exercise the emergency authorities provided for under subsections (A) and (B) of this section shall be responsible for reimbursement of all related costs to the control authority or contributing jurisdiction, as appropriate.

D. The director or the city may require nondomestic users to reduce or curtail certain discharges to the POTW, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial waste-streams, and take all other measures to protect the POTW and determine the nondomestic user’s compliance with the requirements of this chapter.

E. The director or the city, based on the determination that such facilities or devices are necessary for implementation of pretreatment requirements, may require any nondomestic user to install and maintain, on their property and at their expense, pretreatment facilities, devices and equipment that may include, but not be limited to, any of the following:

1. A sampling facility or sampling manhole, whichever the director or the city deems appropriate, accessible to the control authority or contributing jurisdiction;

2. A suitable storage and/or flow equalization tank with representative sampling capabilities;

3. A grease interceptor, grease trap, solids separator, or oil/water separator;

4. An approved hazardous gas detection meter;

Article V. Wastewater Discharge Permits and Control Documents

13.14.500 Nondomestic user screening form.

The control authority is obligated under federal law to identify and locate all possible nondomestic users which might be subject to the pretreatment standards, and to identify the character and volume of pollutants discharged by such nondomestic users. To satisfy this requirement, any possible nondomestic user of the POTW must, upon request of the director, periodically complete a nondomestic user screening form. Users of the POTW shall fully disclose the information requested and sign the completed form in accordance with BLMC 13.14.550. Proper completion of nondomestic user screening requirements is a condition of initial and continued discharge to the POTW. Nondomestic users failing to fully comply with screening requirements within a timeframe specified by the director shall be subject to all enforcement measures authorized under this chapter including termination of service. The director is authorized to prepare several forms for this purpose and require completion of the particular form which the director determines appropriate to provide the information needed to categorize each nondomestic user. The director shall be authorized to categorize each nondomestic user, provide written notice of a nondomestic user’s categorization and what it means, and revise this categorization at any time. (Ord. 1725 § 4, 2024; Ord. 1719 § 1 (Exh. A), 2024).

13.14.510 Wastewater discharge permit requirement.

A. No significant industrial user shall discharge wastewater into the POTW without first obtaining an individual wastewater discharge permit from the director, as the city’s agent in issuing such permits. A significant industrial user or nondomestic user that has filed a timely application pursuant to BLMC 13.14.520 may continue to discharge unless and until notified otherwise by the director.

B. The director, as the city’s agent, may require all other nondomestic users to obtain a wastewater discharge permit, control document, or implement best management practices as necessary to carry out the requirements or otherwise meet the intent of this chapter. For example, a control document may be required solely for flow equalization or for a NDCIU.

C. Any failure to complete the required nondomestic user screening form, apply for and obtain a required permit or other control document, or violate the terms and conditions of a wastewater discharge permit or control document shall be deemed a violation of this chapter and subject the nondomestic user to the sanctions set out in BLMC 13.14.1100 through 13.14.1360. Obtaining a wastewater discharge permit or other control document does not relieve a nondomestic user of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, and local law. (Ord. 1725 § 5, 2024; Ord. 1719 § 1 (Exh. A), 2024).

The report is due within 180 days after the effective date of a categorical pretreatment standard, unless the final administrative decision on a category determination comes later.

B. Nondomestic users that wish to begin discharging wastewater to the POTW from operations subject to categorical pretreatment standards after EPA has published the standards (called new sources), shall submit a baseline monitoring report to the director containing the information listed in subsection (C) of this section. However, for new sources, the report must be provided at least 120 days before desiring to discharge. New sources shall describe the method of pretreatment they intend to use to meet applicable categorical pretreatment standards. Because monitoring data will not be available for proposed facilities, new sources instead must provide estimates of the anticipated flow rates and quantity of pollutants to be discharged.

C. The baseline monitoring report shall include the following information:

1. All information required in BLMC 13.14.540(A)(1) through (A)(9).

2. Additional conditions for existing sources measuring pollutants.

a. Nondomestic users shall take a minimum of three representative sample to compile the data for the baseline monitoring report.

b. Nondomestic users shall take samples immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If the nondomestic user mixes other wastewaters with the regulated wastewater prior to pretreatment, the nondomestic user must provide the flows and concentrations necessary to apply the combined wastestream formula of BLMC 13.14.310(C) and 40 CFR Part 403.6(e). Where the nondomestic user wants an alternate concentration or mass limit, and it is allowed by federal rules at 40 CFR Part 403.6(e), the user shall propose the adjusted limit and provide supporting data to the director.

c. Sampling and analysis shall be performed in accordance with BLMC 13.14.800, Sample collection, and 13.14.790, Analytical requirements.

d. The director may allow the report to use only historical data if the data is good enough to allow the evaluation of whether (and which) industrial pretreatment measures are needed.

e. The baseline monitoring report shall indicate the time, date, and place of sampling, methods of analysis. The user shall certify that the sampling and analysis presented is representative of normal work cycles and expected pollutant discharges to the POTW.

3. Compliance Certification. A statement, reviewed by the authorized representative of the nondomestic user and certified by a qualified professional experienced in the design, construction, and operation of pretreatment facilities indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O&M) and/or additional pretreatment steps are required to meet the pretreatment standards and requirements.

4. Compliance Schedule. While new sources must install the treatment required to meet the pretreatment standards prior to operation, existing sources may be granted a compliance schedule where they must provide additional pretreatment and/or O&M to meet the pretreatment standards. In such cases, the nondomestic user shall propose the shortest schedule by which they can provide the additional pretreatment and/or O&M. The completion date which the nondomestic user proposes in this schedule may not be later than the compliance date established for the applicable pretreatment standard. Any compliance schedule authorized pursuant to this section must also meet the requirements set out in BLMC 13.14.710.

D. Signature and Report Certification. All baseline monitoring reports must be certified in accordance with BLMC 13.14.830(A) and signed by an authorized representative of the user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.710 Compliance schedule progress reports.

The following conditions shall apply to compliance schedules proposed by existing sources according to BLMC 13.14.700(C)(4) and incorporated into permits:

A. The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the nondomestic user to meet the applicable pretreatment standards (such events include, but are not limited to, hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing construction, and beginning and conducting routine operation);

B. No increment referred to above shall exceed nine months;

C. The nondomestic user shall submit a progress report to the director no later than 14 days following each date in the schedule and the final date of compliance including, as a minimum, whether or not it complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the user to return to the established schedule; and

D. In no event shall more than nine months elapse between such progress reports to the director. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.720 Reports on compliance with categorical pretreatment standards deadline.

Both existing sources and new sources must submit a report on whether compliance has been initially achieved. For existing sources, the report is due 90 days after the date applicable categorical pretreatment standards give as the final compliance date. For a new source, the report is due 90 days after starting to discharge to the POTW.

In both cases, the report must contain the information described in BLMC 13.14.540(A)(3) through (A)(6). For existing sources, it must also contain the compliance certification of BLMC 13.14.700(C)(3) and, if needed, the compliance schedule described in BLMC 13.14.700(C)(4). Nondomestic users subject to equivalent mass or concentration limits, as allowed by BLMC 13.14.310, must include a reasonable measure of their long term production rate. Other nondomestic users subject to standards based on a unit of production (or other measure of operation) must include their actual production during the sampling period. All compliance reports must be signed and certified in accordance with BLMC 13.14.830(A). (Ord. 1719 § 1 (Exh. A), 2024).

13.14.730 Periodic compliance reports.

A. The director may specify the necessary minimum sampling and reporting frequencies and include applicable requirements in permits. Significant industrial users (SIUs) must:

1. Report at least twice a year, in June and December unless otherwise specified;

2. Report the flows and concentrations for the reporting period of regulated pollutants in all discharges subject to pretreatment standards;

3. Report average and maximum daily flows for the reporting period and identify where flow estimates are used; and

4. Include the documentation needed to show compliance with applicable BMPs, pollution prevention alternatives, maintenance, treatment, or record keeping requirements.

B. Nondomestic users must sign and certify all periodic compliance reports in accordance with BLMC 13.14.830(A).

C. Nondomestic users must take wastewater samples which are representative of their range of discharge conditions and of any discharge not disclosed in their permit application. Nondomestic users must properly operate, clean, and maintain sampling and flow metering facilities and devices and ensure they function properly. The director will not allow nondomestic user claims that sampling results are unrepresentative due to a nondomestic user’s failure to meet this requirement, without extenuating circumstances approved by the director.

D. Nondomestic users subject to the reporting requirements in this section must report any additional monitoring which might determine compliance with permit requirements. This includes any additional monitoring of regulated pollutant at their respective effluent monitoring locations using procedures prescribed in BLMC 13.14.800. In such cases, the results of this monitoring shall be included in periodic monitoring reports.

E. If a nondomestic user sampled and analyzed more frequently than was required by the director or by this chapter, using methodologies in 40 CFR Part 136, it must submit all results of sampling and analysis of the discharge during the reporting period.

F. Any nondomestic user subject to equivalent mass or concentration limits established by the director or by unit production limits specified in the applicable categorical pretreatment standards, shall report production data as outlined in BLMC 13.14.310(E).

G. Zero discharge nondomestic users shall submit periodic reports as required by the director stating that no industrial wastewater has been discharged to the POTW.

H. If the director calculated limits to factor out dilution flows or nonregulated flows, the nondomestic user will be responsible for providing flows from the regulated process flows, dilution flows and nonregulated flows.

I. Flows shall be reported on the basis of actual measurement; however, the director may accept reports of average and maximum flows estimated by verifiable techniques if the director determines that an actual measurement is not feasible.

J. The director may authorize a categorical industrial user to forego sampling of a pollutant regulated by a categorical pretreatment standard when it is not present in raw wastewater; provided, that:

1. The CIU submits a request for the waiver with their permit application or reapplication;

2. The CIU analyzes a sample (or samples) representative of all wastewater from all processes before any treatment and includes all results with the request;

3. The CIU demonstrates through source water and untreated process water sample results that the pollutant never exceeds intake water levels (pollutants simply reduced by treatment to background levels are ineligible for the waiver);

4. The CIU shows, where nondetectable sample results are returned as provided in subsection (B) or (C) of this section, that they used the method from 40 CFR Part 136 with the lowest detection level;

5. The authorized representative of the user signs the request using the certification statement;

6. The CIU includes in routine monitoring reports, a statement certifying that there has been no increase in the pollutant in its wastestream due to activities of the industrial user; and

7. The CIU reports and immediately resumes the monitoring, which would otherwise have been required upon discovering that a waived pollutant is present or expected to be present based on changes to the user’s operations.

K. The director will document the reasons supporting the waiver in the permit fact sheet, and keep any information submitted by the nondomestic user and the fact sheet for three years after the waiver expires. Monitoring waivers are valid after being incorporated in a nondomestic user’s permit. The waiver is in effect while the permit is effective. The director may cancel a monitoring waiver at any time for cause. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.740 Reports of changed conditions.

Each nondomestic user must notify the director of any substantial changes to the nondomestic user’s operations or system which might alter the nature, quality, or volume of its wastewater. This notification must be made at least 30 days before the desired change and be sent to the director. In such cases:

A. The director may require the user to submit any information needed to evaluate the changed condition. The director may also require a new or revised wastewater discharge permit application under BLMC 13.14.540; and

B. The director may issue, reissue, or modify a wastewater discharge permit applying the procedures of Article VI of this chapter in response to a user’s notice under this section. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.750 Reports of potential problems.

A. Any nondomestic user which has any unusual discharge that could cause problems to the POTW must immediately notify the director by telephone of the incident. This notification shall include the location of the discharge, type of waste, concentration, and volume, if known, and corrective actions taken by the nondomestic user to control and curtail the discharge. Such discharges may include spills, slug loads, accidental discharges, or other discharges of a nonroutine, episodic nature. Problems to the POTW which require reporting under this section include violating pretreatment requirements, pretreatment standards, or other requirements of Article III of this chapter such as vapor toxicity and explosivity limits.

B. Within five days following such discharge, the nondomestic user shall submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the nondomestic user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the nondomestic user of any fines, penalties, or other liability which may be imposed pursuant to this chapter.

C. Nondomestic users required to submit an accidental discharge/slug discharge control plan (per BLMC 13.14.420) shall post notice in a prominent location advising employees who to call at the POTW to inform the director of a potential problem discharge (subsection (A) of this section). Nondomestic users shall ensure that all employees who may cause or witness such a discharge are advised of the emergency notification procedures.

D. All nondomestic users must immediately notify the director of any changes at their facility which might increase their potential for a slug discharge. This includes increasing the volume of materials stored or located on site which, if discharged to the POTW, would cause problems. Nondomestic users required to prepare an accidental discharge/slug discharge control plan under BLMC 13.14.420 shall also modify their plans to include the new conditions prior to, or immediately after making such changes. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.760 Reports of unpermitted users.

All nondomestic users not required to obtain a wastewater discharge permit shall provide appropriate reports to the director as the director may require. This may include, but not be limited to, periodically completing, and signing nondomestic user screening forms, monitoring reports, and reports regarding compliance with best management practices. (Ord. 1725 § 9, 2024; Ord. 1719 § 1 (Exh. A), 2024).

13.14.770 Notice of violation – Repeat sampling and reporting.

If sampling performed by a nondomestic user indicates a violation, the user must notify the director within 24 hours of becoming aware of the violation. The nondomestic user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the director within 30 days after becoming aware of the violation. The director may waive the repeat sampling requirement where the control authority or contributing jurisdiction has sampled the effluent for the pollutant in question prior to the nondomestic user obtaining sampling results. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.780 Notification of the discharge of hazardous waste.

A. Any nondomestic user that proposes to discharge any volume of hazardous waste as defined in 40 CFR 261 (listed or characteristic wastes) or dangerous waste as defined Chapter 173-303 WAC, or any facility that proposes to discharge any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), is required to provide a request in writing to the director. Discharging such waste without the director’s approval as provided herein is prohibited. The request shall be provided with the initial wastewater discharge approval application and repeated with each subsequent reapplication.

B. Any nondomestic user who discharges any substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261, or Chapter 173-303 WAC must also comply with the following requirements:

1. Notify the director, the EPA Region 10 Office of Air, Waste, and Toxics Director, and state hazardous waste authorities, in writing, of the discharge. Maintain a copy of this notification and include it in all subsequent permit applications or reapplications under this chapter.

2. Include the following information in the notification:

a. The name of the hazardous waste as found in 40 CFR Part 261;

b. The EPA hazardous waste number; and

c. The type of discharge (continuous, batch, or other).

3. If the discharge totals more than 220 pounds of hazardous waste in any month, also provide:

a. The hazardous constituents contained in the wastes;

b. An estimate of the mass and concentration of hazardous constituents in the wastestream discharged during that calendar month; and

c. An estimate of the mass of constituents in the wastestream expected to be discharged during the following 12 months.

4. This notice shall be repeated for new or increased discharges of substances subject to this reporting requirement.

5. All notifications must take place prior to discharging a substance for which these reporting requirements apply. If this is not possible, the notice must be provided as soon after discharge as practical and describe why prior notice was not possible.

6. Nondomestic users must provide notifications under this subsection only once to EPA and the state for each hazardous waste discharged. However, all of the information of these notices shall be repeated in each new permit application submitted under this chapter.

7. This requirement does not relieve the nondomestic user from requirements to provide other notifications, such as of changed conditions under BLMC 13.14.540, or applicable permit conditions, permit application requirements, and prohibitions.

8. Pollutants that are reported under the reporting requirements for categorical industrial users in baseline monitoring, final and periodic compliance reports are not subject to the notification requirements in this section.

C. Nondomestic users must report all discharges of more than 33 pounds per month of substances which, if otherwise disposed of, would be hazardous wastes. Nondomestic users must also report any discharge of acutely hazardous wastes as specified in 40 CFR Parts 261.30(d) and 261.33(e). Subsequent months during which the nondomestic user discharges more of a hazardous waste for which notice has already been provided do not require another notification to EPA or the state but must be reported to the director.

D. If new regulations under RCRA describe additional hazardous characteristics or substances as a hazardous waste, the nondomestic user must provide notifications under subsection A of this section, if required by subsection B of this section within 90 days of the effective date of such regulations.

E. For any notification made under this section, the nondomestic user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical and shall describe that program and reductions obtained through its implementation.

F. This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this chapter, a permit issued thereunder, or any applicable federal or state law. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.790 Analytical requirements.

All pollutant sampling and analyses required under this chapter shall conform to the most current version of 40 CFR Part 136, unless otherwise approved by the director or specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for a pollutant, or the director determines that the 40 CFR Part 136 sampling and analytical techniques are inconsistent with the goal of the sampling, the director may specify an analytical method. If neither case applies, users shall use validated analytical methods or applicable sampling and analytical procedures approved by EPA. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.800 Sample collection.

Nondomestic users must ensure all samples they collect to satisfy sampling requirements under this chapter are representative of the range of conditions occurring during the reporting period. Nondomestic users must also ensure that, when specified, samples are collected during the specific period.

A. Nondomestic users must use properly cleaned sample containers appropriate for the sample analysis and sample collection and preservation protocols specified in 40 CFR Part 136 and appropriate EPA guidance.

B. Nondomestic users must obtain samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds using grab sample collection techniques.

C. For certain pollutants, nondomestic users may composite multiple grab samples taken over a 24-hour period. Nondomestic users may composite grab samples for cyanide, total phenols, and sulfides either in the laboratory or in the field and may composite grab samples for volatile organics and oil and grease in the laboratory prior to analysis.

D. For all other pollutants, nondomestic users must employ 24-hour flow-proportional composite samplers unless the director authorizes or requires an alternative sample collection method.

E. The director may authorize composite samples for parameters unaffected by the compositing procedures, as appropriate.

F. The director may require grab samples either in lieu of or in addition to composite sampling to show compliance with instantaneous discharge limits.

G. In all cases, nondomestic users must take care to ensure the samples are representative of their wastewater discharges.

H. Nondomestic users sampling to complete baseline monitoring and 90-day compliance reports required by BLMC 13.14.720 and 13.14.700 must satisfy some specific requirements. These reports require at least four grab samples for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. Nondomestic users may composite samples prior to analysis if allowed in subsection (C) of this section. Where historical sampling data exists; the director may also authorize fewer samples.

I. For periodic compliance reports (BLMC 13.14.730), the director may specify the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.

J. Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated or manufacturing process if no pretreatment exists or as determined by the director and/or contained in the nondomestic user’s wastewater discharge permit. For categorical industrial users, if other wastewaters are mixed with the regulated wastewater prior to pretreatment the nondomestic user shall measure the flows and concentrations necessary to allow use of the combined wastestream formula of 40 CFR 403.6(e) in order to evaluate compliance with the applicable categorical pretreatment standards. For other SIUs, for which the director has adjusted its local limits to factor out dilution flows, the user shall measure the flows and concentrations necessary to evaluate compliance with the adjusted pretreatment standards.

K. All sample results shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges from the user. If a nondomestic user sampled and analyzed more frequently than what was required in its wastewater discharge approval, using methodologies in 40 CFR Part 136, it must submit all results of sampling and analysis of the discharge as part of its self-monitoring report.

L. Where a treated regulated process wastestream is combined prior to treatment with wastewaters other than those generated by the regulated process, the industrial user may monitor either the segregated process wastestream or the combined wastestream for the purpose of determining compliance with applicable pretreatment standards. If the industrial user chooses to monitor the segregated process wastestream, it shall apply the applicable categorical pretreatment standard. If the nondomestic user chooses to monitor the combined wastestream, it shall apply an alternative discharge limit calculated using the combined wastestream formula as provided in 40 CFR 403.6(e). The industrial user may change monitoring points only after receiving approval from the director. The director shall ensure that any change in an industrial user’s monitoring point(s) will not allow the user to substitute dilution for adequate treatment to achieve compliance with applicable requirements. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.810 Date of receipt of reports.

The director will credit written reports as having been submitted on the date of the postmark when mailed via certified mail through the United States Postal Service. Reports delivered in any other manner will be credited as having been submitted on the business day received. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.820 Record keeping.

Nondomestic users subject to reporting requirements of this chapter shall retain the below records for all monitoring required by this chapter and for any additional monitoring which could be used to satisfy minimum monitoring requirements. Nondomestic users must make these records available for inspection and copying at the location of the discharge. Nondomestic users must similarly maintain documentation associated with any best management practices required under authority of BLMC 13.14.330(I). Monitoring records shall include at least:

A. The time, date, and place of sampling;

B. The sampling and preservation methods used;

C. The individual taking the sample, and individuals with control of the sample prior to analysis;

D. The individual performing the analyses and the date the analysis was completed;

E. The analytical techniques or methods used; and

F. The results of analysis.

Nondomestic users are encouraged to retain quality control and quality assurance information provided by the laboratory and submit this information in routine reporting. This information also has value in the event that the sample data is called into question. For analytes for which the state requires use of a certified/accredited laboratory, users must maintain the scope of accreditation for laboratories performing any analyses for them.

Nondomestic users shall maintain the above records for the latest of: at least three years, until any litigation concerning the nondomestic user or the control authority is complete, or for longer periods when the nondomestic user has been specifically notified of a longer retention period by the director. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.830 Certification statements.

A. The following certification statement must be signed by an authorized representative of the nondomestic user and included when submitting any of the following:

1. A permit (re)application in accordance with BLMC 13.14.550;

2. A baseline monitoring report under BLMC 13.14.700;

3. A report on compliance with the categorical pretreatment standard deadlines under BLMC 13.14.720; or

4. A periodic compliance report required by BLMC 13.14.730(A) through 13.14.730(D).

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

B. Certification of Pollutants Not Present. Nondomestic users that have an approved monitoring waiver based on BLMC 13.14.730(J) must also include the following certification statement in each report. This statement certifies that there has been no increase in the pollutant in its wastestream due to activities of the nondomestic user:

Based on my inquiry of the person or persons directly responsible for managing compliance with the Pretreatment Standard for 40 CFR                  ______ [specify applicable National Pretreatment Standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of ______ [list pollutant(s) in the wastewater due to the activities at the facility since filing of the last periodic report under BLMC 13.14.730(A).

(Ord. 1719 § 1 (Exh. A), 2024).

Article VIII. Compliance Monitoring

13.14.840 Right of entry – Inspection and sampling.

G. Federal rules prevent wastewater constituents and characteristics and other effluent data, as defined by 40 CFR Part 2.302 from being recognized as confidential information. (Ord. 1719 § 1 (Exh. A), 2024).

Article X. Publication of Users in Significant Noncompliance

13.14.1000 Publication of users in significant noncompliance.

A. Publishing. The director must annually publish a list of the nondomestic users which, at any time during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and requirements. The list will be published in a newspaper of general circulation that provides meaningful public notice within the jurisdictions served by the POTW.

B. Definition. The term “significant noncompliance” means:

1. Any violation of a pretreatment standard or requirement including numerical limits, narrative standards, and prohibitions, that the director determines has caused, alone or in combination with other discharges, interference or pass through, including endangering the health of POTW personnel or the general public.

2. Any discharge that has caused imminent endangerment to the public or to the environment or has resulted in the director’s exercise of its emergency authority to halt or prevent such a discharge.

3. Any violation(s), including of best management practices, which the director determines will adversely affect the operation or implementation of the local pretreatment program.

4. Chronic violations of wastewater discharge limits, defined here as those in which 66 percent or more of all the measurements taken for the same pollutant parameter taken during a rolling six-month period exceed, by any magnitude, a numeric pretreatment standard or requirement, including instantaneous limits of BLMC 13.14.330.

5. Technical review criteria (TRC) violations, defined here as those in which 33 percent or more of wastewater measurements taken for each pollutant parameter during a rolling six-month period equal or exceed the product of the numeric pretreatment standard or requirement, (including instantaneous limits, as defined by BLMC 13.14.330, multiplied by the applicable criteria. Applicable criteria are 1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH.

6. Failure to meet, within 90 days of the scheduled date, a compliance schedule milestone contained in a wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance.

7. Failure to provide any required report within 45 days after the due date. This includes initial and periodic monitoring reports, and reports on initial compliance and on meeting compliance schedules.

8. Failure to accurately report noncompliance.

C. Applicability. The criteria in subsections (B)(1) through (B)(3) of this section are applicable to all users, whereas the criteria in subsections (B)(4) through (B)(8) of this section are only applicable to significant industrial users and categorical industrial users. (Ord. 1719 § 1 (Exh. A), 2024).

Article XI. Administrative Enforcement Remedies

13.14.1100 Procedures.

The director, as the city’s agent for the enforcement of this chapter, is authorized to take the enforcement actions stated in Articles XI through XIV of this chapter.

The director shall establish enforcement procedures consistent with the provisions of this chapter. The director shall adopt an enforcement response plan consistent with the requirements of state law. Such plan shall ensure that the application of remedies provided for in Articles IX through XI of this chapter is appropriate to the violation, and consistent with the treatment of other nondomestic users. Any person may review or obtain a copy in accordance with applicable local, state and federal public records policies of the enforcement response plan by contacting the director. In response to noncompliance with any requirement of this chapter, the director shall apply its enforcement response plan, which shall be incorporated into the enforcement procedures. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1110 Notification of violation.

The director may serve a written notice of violation on any nondomestic user that the director finds has violated, or continues to violate, any provision of this chapter, including terms or requirements of a permit, order, or a pretreatment standard or requirement. Nondomestic users shall, in response to a notice of violation, provide the director a written explanation of the violation, its cause, and a corrective action plan within 14 calendar days of the receiving this notice. Nondomestic users submitting plans to correct noncompliance must include the specific actions they will take to correct ongoing and prevent future violations at the soonest practicable date. The director’s acceptance of a plan does not relieve a nondomestic user of liability for any violations. The director may also take any action, including emergency actions or any other enforcement action, without first issuing a notice of violation. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1120 Consent orders.

The director may enter into a consent order or other voluntary agreement to memorialize agreements with nondomestic users violating any requirement of this chapter. Such agreements must include the specific action(s) required and date(s) they are to be completed to correct the noncompliance. Such documents must be constructed in a judicially enforceable manner and have the same force and effect as administrative orders issued pursuant to BLMC 13.14.1150 and 13.14.1160. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1130 Compliance review meeting.

The director may order a nondomestic user that has violated or continues to violate any provision of this chapter, a wastewater discharge permit, order, pretreatment standard or requirement, to appear before the director and show cause why the proposed enforcement action should not be taken. Notice shall be served on the nondomestic user specifying the time and place for the meeting, the proposed enforcement action, the reasons for such action, and a request that the user show cause why the proposed enforcement action should not be taken. The notice of the meeting shall be served personally or by registered or certified mail (return receipt requested) at least five days prior to the meeting. Such notice may be served on any authorized representative of the user. A compliance review meeting shall not be a bar against, or prerequisite for, taking any other action against the nondomestic user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1140 Compliance orders.

The director may issue a compliance order to any nondomestic user which has violated any provision of this chapter including a requirement of a permit, order, or a pretreatment standard or requirement. The compliance order may direct that the nondomestic user come into compliance within a specified time, install and properly operate adequate treatment facilities or devices, or take such measures as the director finds are reasonably necessary. These measures may include additional self-monitoring and management practices designed to minimize the amount of pollutants discharged to the POTW. A compliance order may not extend the deadline for compliance established for a pretreatment standard or requirement, or relieve a user of liability for any violation, including a continuing violation. If the nondomestic user does not come into compliance within the time provided, sanitary sewer service may be discontinued. Issuance of a compliance order shall not be a bar against, or a prerequisite for, taking any other action against the nondomestic user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1150 Cease and desist orders.

When the director finds that a nondomestic user has violated, or continues to violate, any provision of this chapter, a wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, or that the user’s past violations are likely to recur, the director may issue an order to the user directing it to cease and desist all such violations and directing the nondomestic user to:

A. Immediately comply with all requirements; and

B. Take such appropriate remedial or preventive action as may be needed to properly address a continuing or threatened violation, including halting operations and/or terminating the discharge. Issuance of a cease and desist order shall not be a bar against, or a prerequisite for, taking any other action against the nondomestic user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1160 Administrative fines.

A. When the director finds that a nondomestic user has violated, or continues to violate, any provision of this chapter, a wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, the director may fine such nondomestic user in an amount not to exceed $5,000. Such fines shall be assessed on a per-violation, per-day basis. In the case of monthly or other long-term average discharge limits, fines may be assessed for each day during the period of violation.

B. The director may add the costs of any emergency response, additional monitoring, investigation, and administrative costs related to the noncompliance and the director’s response to the situation to the amount of the fine.

C. The director will consider the economic benefit enjoyed by a user as a result of the noncompliance in cases where there appears to have been a monetary benefit from not complying. In such cases, the director shall ensure that fines, to the maximum amounts allowable, exceed the benefit to the nondomestic user from the noncompliance.

D. Unpaid charges, fines, and penalties shall, at 30 calendar days past the due date, be assessed an additional penalty at a rate established by the control authority, and interest shall accrue thereafter at a rate established by the control authority. After 30 calendar days the control authority, on its own behalf or as an authorized agent of a contributing jurisdiction, shall be authorized to file a lien against the user’s property for unpaid charges, fines, and penalties.

E. Nondomestic users desiring to dispute such fines must file a written request for the director to reconsider the fine along with full payment of the fine amount within 15 business days of being notified of the fine. Where a request has merit, the director may convene a hearing on the matter. In the event the nondomestic user’s appeal is successful, the director shall rebate the difference between the initial and final penalty amounts to the nondomestic user.

F. Issuance of an administrative fine shall not be a bar against, or a prerequisite for, taking any other action against the nondomestic user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1170 Emergency suspensions.

The director may immediately suspend a nondomestic user’s authorization to discharge to the POTW when the discharge reasonably appears to present a substantial danger to the health or welfare of persons. In such cases, the director will first provide informal notice to the nondomestic user. The director may also immediately suspend nondomestic user’s authorization to discharge, after notice and opportunity to respond, that threatens to interfere with the operation of the POTW, or which presents, or may present, a danger to the environment.

A. Any nondomestic user notified of a suspension of authorization to discharge to POTW shall immediately stop or eliminate the discharge. If a nondomestic user fails to immediately comply voluntarily with the suspension order, the director may take such steps as deemed necessary to protect the public and its interest in the POTW. Remedies available to the director include immediately severing the sanitary sewer connection, at the users expense, turning off pump stations downstream of the nondomestic user, and partnering with law enforcement. The director may not allow the nondomestic user to recommence its discharge until the nondomestic user has demonstrated to the satisfaction of the director that the situation warranting the suspension has been properly addressed and any proposed termination proceeding has been resolved.

B. Any nondomestic user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence. Nondomestic users shall submit this report to the director prior to the date of any compliance review meeting or termination hearing under BLMC 13.14.1130 and 13.14.1180, respectively. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1180 Termination of discharge.

Any nondomestic user who violates any of the following conditions is subject to having the privilege of discharging to the POTW withdrawn:

A. Discharge of nondomestic wastewater without a permit or other control document, including:

1. Where the appropriate permit or control document has not been requested;

2. Where the appropriate permit or control document has not yet been issued; or

3. Where the permit or control document has been denied or revoked based on the provisions of BLMC 13.14.650, Wastewater discharge permit revocation.

B. Violation of permit or other control document terms and conditions including:

1. Exceeding any permit or control document limit;

2. Failing to meet other pretreatment standards or requirements;

3. Violating any prohibition; or

4. Failing to properly monitor and report discharges or changed conditions.

C. Refusal of reasonable access to the nondomestic user’s premises for the purpose of inspection, monitoring, or sampling (whether subject to a permit or not).

D. Violation of the pretreatment standards and requirements in Article III of this chapter, including failure to satisfy nondomestic user screening requirements.

When the director determines this remedy is necessary and appropriate to fulfill the intentions of this chapter, such user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under BLMC 13.14.1130 why the proposed action should not be taken. Exercise of this option by the director shall not be a bar to, or a prerequisite for, taking any other action against the user. (Ord. 1725 § 11, 2024; Ord. 1719 § 1 (Exh. A), 2024).

Article XII. Judicial Enforcement Remedies

13.14.1220 Injunctive relief.

The director may seek injunctive relief when a user has violated, or continues to violate a provision of this chapter, including a pretreatment standard or requirement, or a permit or order issued hereunder. In such cases, the director may petition the superior court of Pierce County for temporary or permanent injunctive relief, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, control document, order, or other requirement imposed by this chapter on activities of the nondomestic user. The director may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the nondomestic user to conduct environmental remediation. A petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against a nondomestic user. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1230 Civil penalties.

A. A nondomestic user which has violated, or continues to violate a provision of this chapter, including a pretreatment standard or requirement, or a permit or order issued hereunder shall be liable to the control authority for a maximum civil penalty of $5,000 per violation, per day. In the case of a monthly or other long-term average discharge limit, penalties shall accrue for each day during the period of the violation. Any such assessment, penalty, or charges shall constitute a lien against the individual user’s property.

B. The director may recover reasonable attorneys’ fees, court costs, and other expenses associated with any emergency response, enforcement activities, additional monitoring and oversight, and costs of any actual damages to the POTW.

C. Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, any other action the director may take to resolve noncompliance by a nondomestic user.

D. A nondomestic user’s failure to pay such civil penalties shall constitute a violation of this chapter and be grounds for termination of sanitary sewer utility services and revocation of the wastewater discharge permit or other control document or mechanism. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1240 Criminal prosecution.

A. A nondomestic user who willfully or negligently violates any provision of this chapter, a wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement shall, upon conviction, be guilty of a misdemeanor, punished by a fine of not more than $1,000 per violation, per day, or imprisonment for not more than 90 days in jail, or both.

B. A nondomestic user who willfully or negligently introduces any substance into the POTW which causes personal injury or property damage shall, upon conviction, be guilty of a misdemeanor. This penalty shall be in addition to any other criminal charges or judicial remedies, including remedies for causing personal injury, endangerment, or destruction of public property available under state law.

C. A nondomestic user who knowingly makes any false statements, representations, or certifications in any application, record, report, plan, or other documentation filed, or required to be maintained, pursuant to this chapter, wastewater discharge permit, or order issued hereunder, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under this chapter shall, upon conviction, be guilty of a misdemeanor.

D. In the event of a second criminal conviction of this chapter, a nondomestic user shall, upon conviction, be guilty of a gross misdemeanor, punished by a fine of not more than $5,000 per violation, per day, or imprisonment for not more than 364 days in jail, or both. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1250 Remedies nonexclusive.

The remedies provided for in this chapter are not exclusive. The director may take any, all, or any combination of these actions against a noncompliant user. Enforcement of pretreatment violations will generally be in accordance with the control authority’s enforcement response plan.

However, the director may take other action against any user when the circumstances warrant. Further, the director is empowered to take more than one enforcement action against any noncompliant user. (Ord. 1719 § 1 (Exh. A), 2024).

Article XIII. Supplemental Enforcement Action

13.14.1300 Supplemental penalties.

A. The director may assess a penalty of $100.00 to any nondomestic user for each day that a report required by this chapter, a permit or order issued hereunder is late. The director’s actions to collect late reporting penalties shall not limit the director’s authority to initiate any other enforcement action. Nondomestic users desiring to dispute such fines must follow the procedures in BLMC 13.14.1160.

B. The director may assess a penalty of $100.00 for each day that a nondomestic user or establishment where fats, oils and grease may be introduced into the POTW is not in compliance with the routine maintenance schedule as authorized in BLMC 13.14.410(H). The director’s actions to collect penalties for noncompliance per this section shall not limit the director’s authority to initiate any other enforcement action. Nondomestic users desiring to dispute such fines must follow the procedures in BLMC 13.14.1160(E). (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1310 Performance bonds.

The director may require a satisfactory bond, payable to the control authority, in a sum not to exceed a value determined by the director as necessary to assure the nondomestic user will achieve consistent compliance with this chapter. The director may require this bond as an enforcement response or as a prerequisite to issue or reissue a wastewater discharge permit. Any nondomestic user who has failed to comply with any provision of this chapter, a previous permit or order issued hereunder, or any other pretreatment standard or requirement may be subject to this requirement. This bond may also be required of any category of user which has led to public burdens in the past regardless of the compliance history of the particular user. The control authority may use this bond to pay any fees, costs, or penalties assessed to the user whenever the nondomestic users account is in arrears for over 30 days. This includes the costs of cleanup of the site if the nondomestic user goes out of business, sells the business to a person that does not first assume the bond, or goes bankrupt. Nondomestic users may petition the director to convert their performance bond to a requirement to provide liability insurance, or to forego any such safeguard based on their performance. A nondomestic user may petition no more frequently than once in any 12-month period. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1320 Liability insurance.

The director may require any nondomestic user to provide insurance if they previously failed to comply with any provision of this chapter, a previous permit, or order issued hereunder, or any other pretreatment standard or requirement. The director may also require nondomestic users in businesses which historically have left a public burden to clean up pollution to obtain this insurance, regardless of their compliance history. In such cases, nondomestic users must provide proof that the insurance is sufficient to cover any liabilities incurred under this chapter, including the cost of damages to the POTW and the environment caused by the user. The director may require nondomestic users to provide the proof of such insurance either in response to noncompliance or prior to issuing or reissuing a wastewater discharge permit. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1330 Payment of outstanding fees and penalties.

The director may decline to issue or reissue a wastewater discharge permit to any nondomestic user who has failed to pay any outstanding fees, fines or penalties incurred as a result of any provision of this chapter, a previous permit or order issued hereunder. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1340 Water supply severance.

The director may order water service to a nondomestic user severed whenever a nondomestic user has violated or continues to violate any provision of this chapter, a permit, or order issued hereunder, or any other pretreatment standard or requirement; provided, that if the city is the water utility service provider, the director must obtain the approval of the city in order to have authority to order the water service to be severed. Nondomestic users wishing to restore their service must first demonstrate their ability to comply with this chapter and pay the related costs of this action. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1350 Public nuisances.

A violation of any provision of this chapter or a permit or order issued hereunder, or any other pretreatment standard or requirement, is hereby declared a public nuisance and shall be corrected or abated as directed by the director or the city. Any person(s) creating a public nuisance shall be subject to the provisions of applicable law governing such nuisances, including reimbursing the control authority for any costs incurred in removing, abating, or remedying said nuisance. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1360 Contractor listing.

Nondomestic users which have not achieved compliance with applicable pretreatment standards and requirements may not be eligible to receive a contractual award for the sale of goods or services to the control authority or contributing jurisdiction. Existing contracts for the sale of goods or services to the control authority or contributing jurisdiction held by a nondomestic user found to be in significant noncompliance with pretreatment standards or requirements may be terminated at the discretion of the director. (Ord. 1719 § 1 (Exh. A), 2024).

Article XIV. Affirmative Defenses to Discharge Violations

13.14.1400 Upset.

A. For the purposes of this article, the word “upset” means an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards because of factors beyond the reasonable control of the user. An upset does not include noncompliance to the extent caused by operational error, improperly designed pretreatment facilities, inadequate pretreatment facilities, lack of preventive maintenance, or careless or improper operation.

B. An upset shall constitute an affirmative defense to punitive actions in response to noncompliance with categorical pretreatment standards BLMC 13.14.320, but not local limits BLMC 13.14.340, when the requirements of subsection (C) of this section are met.

C. A nondomestic user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

1. An upset occurred and the user can identify the cause(s) of the upset.

2. The facility was at the time being operated in a prudent and workman-like manner and was in compliance with applicable operation and maintenance procedures.

3. Where the upset involved reduction, loss, or failure of its pretreatment facility (e.g., a power failure), the user controlled production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards until the facility was restored or an alternative method of treatment was provided.

4. The nondomestic user submitted the following information to the director within 24 hours of becoming aware of the upset. When initially provided orally, the nondomestic user must have provided a written report within five days that includes:

a. A description of the indirect discharge and cause of noncompliance;

b. The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and

c. Steps being taken and/or planned to reduce, eliminate, and prevent recurrence of the noncompliance.

D. In any enforcement proceeding, the nondomestic user seeking to establish the occurrence of an upset shall have the burden of proof.

E. Users will have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for noncompliance with categorical pretreatment standards. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1410 Prohibited discharge standards.

A nondomestic user will have an affirmative defense to an enforcement action brought against it for noncompliance with the prohibitions in BLMC 13.14.300(A) and 13.14.300(B)(3) through (B)(7) in certain cases. The nondomestic user must be able to prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause pass through or interference and that either:

A. A local limit exists for each pollutant discharged and the nondomestic user was in compliance with each limit directly prior to, and during, the pass through or interference; or

B. No local limit exists, but the discharge did not change substantially in nature or constituents from the nondomestic user’s prior discharge when the control authority was regularly in compliance with its NPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1420 Bypass.

A. For the purposes of this article, “severe property damage” means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. “Severe property damage” does not mean economic loss caused by delays in production.

B. A nondomestic user may be authorized to allow a bypass to occur if it does not cause pretreatment standards or pretreatment requirements to be violated and is for essential maintenance to assure efficient operation.

C. Any other bypass must meet the following requirements:

1. Nondomestic users knowing in advance of the need for a bypass must submit prior notice to the director, at least 10 days before the bypass whenever possible; and

2. Nondomestic users must notify the director of any unanticipated bypass that exceeds applicable pretreatment standards within 24 hours of becoming aware of the bypass. Nondomestic users must provide a written follow-up report within five days. The director may waive the written report if the oral report was timely and complete. Unless waived, the written report must contain:

a. A description of the bypass (volume, pollutants, etc.);

b. What caused the bypass;

c. When, specifically, the bypass started and ended;

d. When the bypass is expected to stop (if ongoing); and

e. What steps the user has taken or plans to take to reduce, eliminate, and prevent the bypass from reoccurring.

D. Bypass is prohibited, and the director may take an enforcement action against a user for a bypass, unless:

1. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

2. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and

3. The nondomestic user submitted notices as required under subsection (C) of this section.

E. The director may approve an anticipated bypass, after considering its adverse effects, if the director determines that it will meet the three conditions listed in subsection (E) of this section. (Ord. 1719 § 1 (Exh. A), 2024).

Article XV. Administrative Hearing

13.14.1500 Right to administrative hearing.

A. Any affected nondomestic user shall have the right to an administrative hearing to appeal the director’s determination to take any of the following actions:

1. Issue or deny a nondomestic user’s wastewater discharge permit or other control document;

2. Impose particular conditions or requirements in a nondomestic user’s wastewater discharge permit or other control document;

3. Suspend a nondomestic user’s wastewater services or wastewater discharge permit or other control document pursuant to BLMC 13.14.1170;

4. Terminate the nondomestic user’s wastewater services or wastewater discharge permit or other control document pursuant to BLMC 13.14.1180;

5. Modify the nondomestic user’s wastewater discharge permit or other control document pursuant to BLMC 13.14.630;

11. Assess damages and costs against the user pursuant to BLMC 13.14.1230;

12. Impose any other discretionary action upon the user, or deny any discretionary action requested of the director by the user, if such action or omission directly affects the nondomestic user; or

13. Take any other action with respect to the user which requires the opportunity for hearing by state law or constitutional right. (Ord. 1725 § 12, 2024; Ord. 1719 § 1 (Exh. A), 2024).

13.14.1510 Request for administrative hearing.

A. A hearing pursuant to this article shall be requested by the nondomestic user, in writing to the director within 15 business days of the user’s actual notice of the director’s action or determination from which the user seeks appeal. Failure to request such hearing within this period shall constitute a waiver of the right to administrative hearing, unless the director determines that good cause exists for the delay.

B. Any request for administrative hearing shall adequately identify the affected nondomestic user, the director’s action or determination from which the user seeks appeal, and the basis or reasons for the appeal.

C. The director shall respond to all requests for administrative hearing within 15 business days of receipt of request from the user, or five business days if the user is contesting suspension of wastewater services, permit, or other control document.

D. The director may deny a request for hearing if the request is untimely, the action contested is not subject to appeal, or if the director determines in good faith that the request is incomplete or additional information is needed to identify the user, determine the particular action or decision appealed, or determine the basis or reasons for appeal. If the request is denied, the director shall state the basis for the denial in the director’s response.

E. If the request for hearing is granted, the director shall set a date for hearing no sooner than 10 days or later than 30 days from the date of the director’s response to the request. The director may extend the date for hearing upon good cause for delay and timely notice to the nondomestic user.

F. The director’s response granting an administrative hearing shall notify the nondomestic user of the following items:

1. The names and addresses of all parties to whom notice has been sent;

2. The mailing address and telephone number of the department or office designated to represent the director, typically the control authority or contributing jurisdictions’ attorney’s office;

3. The official file or reference number and name of the proceeding;

4. The name, title, mailing address, and telephone number of the appointed hearings officer, if known;

13.14.1520 Hearings officer.

A. The hearings officer for an administrative hearing under this article shall be the city’s hearing examiner.

B. A person that has served as an investigator, prosecutor, or advocate in an adjudicative proceeding, or in its pre-adjudicative stage, or one who is subject to the authority, direction, or discretion of such a person, may not serve as a hearings officer in the same proceeding. (Ord. 1719 § 1 (Exh. A), 2024).

13.14.1530 Petition for disqualification.

A. Any party to the hearing may present a written petition for disqualification of a designated hearings officer. A hearings officer shall be subject to disqualification for actual bias, prejudice, interest, or any other cause sufficient to disqualify a judge under state law. Such petition shall particularly describe the basis or reasons asserted for disqualification, and must be submitted to the designated hearings officer within 10 days of official notice of the hearings officer’s identity, or within five days of actual knowledge of the basis for disqualification, whichever is longer. Failure to timely submit a petition for disqualification shall result in a waiver of that party’s objection to the hearings officer. Petition for disqualification must be submitted at least two days prior to hearing date.
