Editor's note— Ord. No. 21-14 N.S., § I, adopted Nov. 18, 2014, amended Ch. 12.18 in its entirety to read as herein set out. Former Ch. 12.18, §§ 12.18.010—12.18.140.1, pertained to the same subject matter, and derived from Ord. No. 18-11 N.S., § I, adopted July 26, 2011. See Ordinance List and Disposition Table for prior derivation.

This chapter sets forth the requirements of users of the Richmond Municipal Sewer District Water Pollution Control Plant and its collection system (collectively, called the POTW in this chapter) for the City of Richmond (City), and enables the City to comply with all applicable State and Federal laws, including the Clean Water Act (Title 33 of the United States Code [USC] Section 1251 et seq.) and the General Pretreatment Regulations (Title 40 of the Code of Federal Regulations [CFR] Part 403). The objectives of this chapter are:

A. To prevent the introduction of pollutants into the POTW that will interfere with its operations;

B. To prevent the introduction of pollutants into the POTW that will pass through the POTW, inadequately treated, into receiving waters or atmosphere, or otherwise be incompatible with the POTW;

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

D. To promote reuse and recycling of wastewater, sludge, gases, and other byproducts from the POTW;

E. To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the POTW;

F. To prevent sanitary sewage overflows as a result of grease obstructions that subject the City and the public to adverse health risks, State Water Resources Control Board penalties, and civil lawsuits, impact service continuance, and diminish stormwater quality;

G. To comply with San Francisco Bay Regional Water Quality Control Board regulations for establishing a sanitary sewer overflow plan that also includes a fats, oils, and grease control plan;

H. To enable the City to comply with its National Pollutant 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 users of the POTW. The ordinance authorizes the issuance of individual and general wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for equitable distribution of costs resulting from the program established herein.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users must comply with the categorical pretreatment standard found in 40 CFR Chapter I, Subpart N, Parts 405-471.

A. Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the City Manager may impose equivalent concentration or mass limits in accordance with subsections 12.18.020.2(F) through (G).

B. When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the City Manager may convert the limits to equivalent limitations expressed either as a mass of pollutant discharged per day or effluent concentration for the purposes of calculating effluent limitations applicable to individual industrial users.

C. When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the City Manager shall impose an alternate limit in accordance with 40 CFR Part 403.6(e).

D. A CIU may obtain a net/gross adjustment to a categorical pretreatment standard in accordance with the following subsections of this section:

(1) Categorical pretreatment standards may be adjusted to reflect the presence in the industrial user's intake water in accordance with this section. Any industrial user seeking to obtain credit for intake pollutants must make an application to the City. Upon request of the industrial user, the applicable standard will be calculated on a "net" basis (i.e., adjusted to reflect credit for pollutants in the intake water) if the requirements of Section 12.18.020.2(D)(2) are met.

(2) Criteria.

(a) Either (i) the applicable categorical pretreatment standards contained in 40 CFR subchapter N specifically provide that they shall be applied on a net basis; or (ii) the industrial user demonstrates that the control system it proposes or uses to meet applicable categorical pretreatment standards would, if properly installed and operated, meet the standards in the absence of pollutants in the intake waters.

(b) Credit for generic pollutants such as biochemical oxygen demand (BOD), total suspended solids (TSS), and oil and grease should not be granted unless the industrial user demonstrates that the constituents of the generic measure in the user's effluent are substantially similar to the constituents of the generic measure in the intake water or unless appropriate additional limits are placed on process water pollutants either at the outfall or elsewhere.

(c) Credit shall be granted only to the extent necessary to meet the applicable categorical pretreatment standard(s), up to a maximum value equal to the influent value. Additional monitoring may be necessary to determine eligibility for credits and compliance with standard(s) adjusted under this section.

(d) Credit shall be granted only if the user demonstrates that the intake water is drawn from the same body of water as that into which the POTW discharges. The City may waive this requirement if it finds that no environmental degradation will result.

E. When a categorical pretreatment standard is expressed only in terms of pollutant concentrations, an industrial user may request that the City convert the limits to equivalent mass limits. The determination to convert concentration limits to mass limits is within the discretion of the City Manager. The City may establish equivalent mass limits only if the industrial user meets all the conditions set forth in Section 12.18.020.2(E)(1)(a) through (e).

(1) To be eligible for equivalent mass limits, the industrial user must:

(a) Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its wastewater discharge permit;

(b) Currently use control and treatment technologies adequate to achieve compliance with the applicable categorical pretreatment standard, and not have used dilution as a substitute of treatment;

(c) Provide sufficient information to establish the user's actual average daily flow rates for all waste streams, based on data from a continuous effluent flow monitoring device, as well as the user's long-term average production rate. Both the actual average daily flow rate and the long-term average production rate must be representative of current operating conditions;

(d) Not have daily flow rates, production levels, or pollutant levels that vary so significantly that equivalent mass limits are not appropriate to control the discharge; and

(e) Have consistently complied with all applicable categorical pretreatment standards during the period prior to the industrial user's request for equivalent mass limits;

(2) An industrial 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 user's flow rates through the use of a continuous effluent flow monitoring device;

(c) Continue to record the user's production rates and notify the City Manager whenever production rates are expected to vary by more than twenty percent (20%) from its baseline production rates determined in Section 12.18.020.2(F) of this chapter. Upon notification of a revised production rate, the City Manager will reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and

(3) Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to Section 12.18.020.2(E)(1)(a) of this chapter so long as it discharges under an equivalent mass. When developing equivalent mass limits, the City Manager:

(a) Will calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the industrial user by the concentration-based daily maximum and monthly average standard for the applicable categorical pretreatment standard and the appropriate unit conversion factor;

(b) Upon notification of a revised production rate, will reassess the equivalent mass limit and recalculate the limit as necessary to reflect changed conditions at the facility; and

(c) May retain the same equivalent mass limit in subsequent wastewater discharge permits terms if the industrial user's actual average daily flow rate was reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit were not based on the use of dilution as a substitute for treatment pursuant to Section 12.18.020.6 of this chapter. The industrial user must also be in compliance with Section 12.18.130.3 of this chapter regarding the prohibition of bypass.

F. The City Manager may convert the mass limits of the categorical pretreatment standards of 40 CFR Parts 414, 419, and 455 to concentration limits for the purposes of calculating limitations applicable to individual industrial users. The conversion is at the discretion of the City Manager.

G. Once included in its wastewater discharge permit, the industrial user must comply with the equivalent limitations developed in this section in lieu of the promulgated categorical pretreatment standards from which the equivalent limitations were derived.

H. Many categorical pretreatment standards specify one limit for calculating maximum daily discharge limitations and second limit for calculating maximum monthly average, or 4-day average, limitations. Where such categorical pretreatment standards are being applied, the same production or flow figure shall be used in calculating both the average and maximum equivalent limitation.

I. Any industrial user operating under a wastewater discharge permit incorporating equivalent mass or concentration limits calculated from a production-based categorical pretreatment standard shall notify the City Manager within two (2) business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not notifying the City Manager of such anticipated change will be required to meet the mass or concentration limits in its wastewater discharge permit that were based on the original estimate of the long-term average production rate.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users must comply with all applicable State pretreatment standards. In the event that either state or federal requirements and standards for discharges to the POTW are more stringent than the limitations, requirements, and standards set forth in this chapter, the most stringent standard or requirement shall apply. Modifications of the Federal or State standards and requirements which are more stringent than the limitations, standards, and requirements as set forth in this chapter and are promulgated subsequent to the adoption of this chapter shall be applied to discharges to the POTW at such time and in such manner as is set forth in Section 12.18.050.4 of this chapter.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. The City is authorized to establish local limits pursuant to 40 CFR Part 403.5(c).

B. No user shall discharge wastewater to the POTW which exhibits any characteristic specifically prohibited by an action of the City Council, or any wastewater containing constituents in excess of any specific constituent level limitations as may be set by the City Council. Effective January 1, 2015, specific pollutant limitations regarding waste characteristics and/or constituent limits may be adopted by resolution. The specific pollutant limitations adopted by resolution shall be daily maximum limits unless otherwise specified.

C. Any violation of a specific pollutant limitation as may be set forth in this chapter or by a City Council resolution shall subject the user to the same administrative actions, penalties, and/or enforcement actions as would be available for any other violation of this chapter. The term "ordinance" as used elsewhere within this chapter, shall be read to include the specific pollutant limitations as set forth in this chapter or as may be set forth by resolution.

D. The following pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing in excess of the following (daily maximum limit):

The above limits apply at the point where the wastewater is discharged to the WPCP. The City Engineer may impose mass limitations in addition to the concentration-based limitations above.

E. The City may develop BMPs, by ordinance or in individual or general wastewater discharge permits, to implement local limits and the requirements of Section 12.18.020.1.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City reserves the right to establish, by ordinance or in individual or general wastewater discharge permits, more stringent standards or requirements on discharges to the POTW consistent with the purpose of this chapter.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

No 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 limitation unless expressly authorized by an applicable pretreatment standard or requirement. The City Manager may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements, or in other cases where imposition of mass limitations is appropriate.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Section 12.18.020 of this chapter within the time limits specified by EPA, the State, or the City, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the City Manager for review, and shall be acceptable to the City Manager before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the City under the provisions of this chapter.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. Fats, Oils, and Grease Program.

(1) Fats, Oils, and Grease Interceptors.

(a) FOG separators and grease interceptors shall be provided, at the user's expense, where, in the opinion of the City Manager, they are necessary for proper handling of wastes containing these substances in excessive amounts, or any flammable wastes or harmful ingredients. All grease interceptors shall be of a type and capacity approved by the City Manager, and shall be located so they are readily and easily accessible for inspection and cleaning.

(b) FOG separators and grease interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction and equipped with removable covers.

(c) Exterior in-ground grease interceptors are required for any establishment with greater than nine drainage fixture units within areas where FOG is generated. The grease interceptor shall be a two-stage grease interceptor with a minimum capacity of one thousand gallons. Larger grease interceptor(s) may be required based on the total amount of drainage fixture units as per the most current State of California Plumbing Code.

(d) Prep sinks, mom sinks and floor drains may be required to be connected to a grease removal device at the discretion of the City Manager or his designees.

(e) For any indirect waste systems where hub drains and floor sinks are used as a receptor for dishwashers, two- and three- compartment sinks, or other similar fixtures, the drainage fixture unit count shall be twice the floor sink or hub drain fixture unit count and the drainage fixture count for the indirect waste source is not counted.

(f) FOG separators shall be located upstream of any dishwashers or discharges exceeding one hundred ten degrees Fahrenheit.

(g) Where installed, all FOG separators or grease interceptors shall be maintained and in continuous efficient operation at all times.

(2) These facilities must have a FOG management program permit. An authorized inspector and/or the City Manager shall have right of entry as described in Section 12.18.070.1 of this chapter.

(3) Fees, charges, and penalties are pursuant to Sections 12.18.100.5, 12.18.100.13, 12.18.110.2, and 12.18.140.1 of this chapter.

(4) Dishwashers and food grinders are prohibited from discharging through the grease trap pursuant to the State of California Plumbing Code.

(5) A grease collection service shall be required for all facilities that generate FOG.

(6) If significant grease accumulation (e.g., a partial blockage) is found downstream or if significant grease wicking is found upstream of the process of concern, an authorized inspector and/or the City Manager may inspect the facility. The inspection will include a review of the grease management program, treatment system, waste storage area, and drains not flowing to the treatment system. BMPs not in place, hauler receipts for the prior three (3) years not available, and/or training documents not current may result in future inspections with an assessed fee as published in the City's Master Fee Schedule (see Section 12.18.140.1).

(7) If a business is shown to be the cause of a grease-related sewer overflow, the user will be responsible for the cost of clean-up as set forth in Section 12.18.140.1.

B. Administration of the FOG Program. The City shall administer a FOG program, which is intended to prevent fats, oils, and grease, and other substances that are likely to block or create a hazard within the sewer system from entering the system through use of grease interceptors or grease traps. The City may require any non-domestic user to install a grease interceptor or grease trap according to the guidelines set forth in the City's standard specifications or other program prior to or at any time after connection to the POTW if the City discovers or determines subsequent to the connection of the facility, the user produces a waste with characteristics that would require installation of a grease interceptor or grease trap pursuant to this chapter.

The installation of a proper grease interceptor or grease trap device shall be the responsibility of the user that applies for the connection or wastewater discharge permit. The City shall determine whether a grease interceptor, grease trap, or other interceptor is required on a case-by-case basis based on an evaluation of the following criteria, including, but not limited to:

(1) The type of user (restaurant, bakery, cheese factory, yogurt shop, gas station, lube facility, etc.);

(2) The volume of the user's business or operation (number of meals served, number of seats, hours of operation, etc.);

(3) Size and nature of facilities (including kitchen facilities) based on size, type, number of fixtures, and types of processing and/or cooking equipment used;

(4) The type of service provided or operation undertaken (such as dine-in meal service versus carry-out meal service);

(5) The type of foods and other materials used in the cooking, processing, or manufacturing operations carried on within the user's facility;

(6) The overall potential for grease-laden, flammable, or sand-laden discharges; and

(7) The existence of devices, procedures, or processes which are designed to minimize the amount of grease, sand, oil, or other flammable liquids from entering the sewer system.

The design, location, and procedures for operation of a required grease interceptor or grease trap shall be approved by the City. Such approval shall be obtained prior to the user's connection of the facility to the POTW, in the event of new construction or remodeling. In instances where a user has already connected and the City determines that a grease interceptor or grease trap must be installed, the user shall promptly provide for the installation of the device, including providing such design and operational plans as may be required. The installation of a grease interceptor or grease trap as required by this chapter on an existing user facility shall occur within a reasonable time not to exceed sixty (60) days after the user has been provided notice that a grease interceptor or grease trap must be installed. This time limit may only be extended by the City in a written agreement.

C. Grease Interceptor Maintenance Procedures and Program. Any user, required by the City and/or this chapter to install and/or operate a grease interceptor or grease trap, shall adequately maintain the device so that the device is in proper working order at all times. Grease and oil interceptors shall be cleaned by a licensed and permitted waste hauler on a periodic basis to ensure that the grease interceptor will be operated as designed at all times. Any user, required to install or have in operation a grease interceptor or grease trap pursuant to this chapter, shall have a plan of operation or program for their facility that is intended to ensure that the grease interceptor or grease trap operates as designed to prevent grease, oil, sand, or other harmful constituents from entering the sewer system. These procedures may include adoption of kitchen practices to minimize grease-laden garbage, which may ultimately enter the facility's drains and floor traps and/or other such procedures as may be required for proper operation of the grease interceptors.

(1) Grease interceptors shall be cleaned out completely by a FOG collection service as necessary to assure that the grease interceptor will operate as designed at all times or as otherwise specified by the City.

(2) Decanting or discharging of removed waste back into the grease interceptor, for the purpose of reducing the volume to be hauled, is prohibited.

(3) The use of additives, directly or indirectly to the plumbing or sewer system, to emulsify grease and/or oil, is specifically prohibited.

(4) The use of biological additives as a supplement to grease interceptor maintenance, including the addition of microorganisms, may be authorized by the City Manager. Approval shall be obtained (in writing) prior to use of such additives.

(5) Maintenance records indicating date of service, volume pumped, name of waste hauler, and waste disposal location for each pumping of the grease interceptor must be kept for a minimum of three (3) years. The records must be provided to the City Manager when requested during normal business hours.

(6) All waste removed from a grease interceptor must be disposed of at a user permitted by Contra Costa County or other applicable regulatory agencies to receive such waste. Pumped out FOG shall not be returned to the sewer system, nor any private wastewater system, nor storm drains.

(7) Any fixture connected to a grease interceptor shall have a non-removable, secured food strainer of such integrity so as to withstand daily operational usage.

(8) Any and all authorized Inspectors shall request a facility representative to open a grease trap and/ or grease interceptor. If there is not a facility representative present that is able to open the grease trap or grease interceptor, the Inspector may elect to open the grease trap or grease interceptor with permission from the facility representative. The Inspector is not liable for any damage to the grease trap or grease interceptor during the inspection.

D. Best Management Practices.

(1) Drain Screen. Drain screens shall be installed on all drainage pipes for all new food services establishments deemed by the City Manager to generate FOG.

(2) Waste FOG.

(a) All waste FOG shall be collected and stored properly in recycling barrels, drums, or bins.

(b) Such recycling barrels, drums, or bins shall be maintained appropriately to ensure they do not leak or enter the City's stormwater collection system by direct discharge or by commingling with stormwater.

(c) A licensed collection service must be used to dispose of waste FOG.

(3) Food Waste. All food waste shall be disposed of directly into the trash or garbage and not in sinks.

(4) Employee Training.

(a) Employees of food service establishments shall be trained upon employment and then annually thereafter, on the following subjects:

(i) How to "dry wipe" pots, pans, dishware, and work areas before washing to remove FOG.

(ii) How to properly dispose of food waste and solids in enclosed plastic bags prior to disposal in trash bins or containers to prevent leaking and odors.

(iii) The location and use of absorption products to clean under fryers and other locations where grease may be spilled or dripped.

(b) Training shall be documented and employee signatures retained indicating each employee's attendance and understanding of the practices.

(c) Training records shall be available for review at any reasonable time by an authorized inspector and/or the City Manager.

(5) Kitchen exhaust filters shall be cleaned as frequently as necessary in order to maintain good operating condition.

(6) All BMPs shall be posted conspicuously in the food preparation and dishwashing areas and process areas at all times.

E. Grease Separators (Traps) for Treating FOG Wastes.

(1) Facilities that have FOG, but are not required to have a grease interceptor, must have an adequate-sized grease trap as determined by the City Manager.

(2) Required connections to grease traps: all three compartment sinks, scullery (preparation) sinks, and pre-wash sinks at dishwashing stations.

(3) Prohibited connections or additives to grease traps:

(a) Final rinse discharge from automatic dishwashers/sanitizers shall not be connected to the grease trap.

(b) Chemical additives, such as chlorinated solvents, or any other additives that causes the emulsification of grease, are strictly prohibited from use in any grease trap.

(4) Maintenance of the grease trap shall be as often as required to maintain it in an efficient operating condition.

(5) For ease of inspection and maintenance, the area around the grease trap must be kept free of storage and the top of the grease trap must not be bolted down.

(6) A maintenance log for the grease trap must be kept for a minimum of three (3) years and must be provided at the request of the City.

F. Grease Interceptors for Treating FOG Wastes.

(1) Grease interceptors shall be required for new food handling facilities constructed after March 1, 2006.

(2) Grease interceptors are required for food handling facilities that generate FOG when there is remodeling, additions, alterations, or repairs valued at or greater than what is specified in the City's fee schedule.

(3) Effective March 1, 2006, those food handling facilities operating without a grease interceptor shall, within six (6) months of written notification by the City Manager, be required to install a grease interceptor if the City Manager determines that the food service establishment is not adhering to the BMP set forth in Section 12.18.030.2(D) of this chapter, or that the food service establishment has caused or contributed to a sewer system blockage resulting in maintenance requirements and/or sewage spills.

(4) All new grease interceptors shall be designed, constructed, and installed in accordance with the current City of Richmond Building and Plumbing Codes, and shall be subject to approval by the Building Regulations and the Water Resource Recovery Departments.

(5) All submitted drawings shall be prepared by a licensed and registered professional engineer. Any false information or misleading calculations submitted shall be the responsibility of the user.

(6) All grease interceptors shall be located such that they are readily and easily accessible for cleaning, inspection, and removal of intercepted waste.

(7) A common grease interceptor shared by multiple businesses can be utilized if specifically authorized by the City Manager upon evidence of legal operating and maintenance agreements between the involved users.

A. The City will classify all users in accordance with the principal activity conducted on the premises where the discharge occurs. The purpose of the classification is to facilitate regulation of discharges to City facilities on the basis of each user's waste quality, quantity, and flow. The classification shall further provide a means of imposing an appropriate level of oversight, control, and enforcement according to the source of the discharge. The classification system will also allow equitable recovery of City capital and operating costs for the environmental compliance program. As set forth in the definition section of this chapter, there are two (2) categories of users; to wit, domestic users and industrial users. Industrial users are categorized as:

B. All users are subject to the prohibitions set forth in this chapter, with such Federal and State statutes and regulations as may apply, and the specific pollutant limitations as may be promulgated by the City Council either by ordinance or resolution.

C. Domestic users under normal circumstances will not be required to apply for or receive a wastewater discharge permit as defined in this chapter, providing that said domestic user discharges only that wastewater which is consistent with the definition of domestic wastewater set forth herein.

D. Industrial users may be subject to wastewater discharge permit requirements depending on the volume, characteristics, and origin of their wastewater discharge. Industrial users may be required to supply such information and data concerning their processes, including discharge samples and wastes generated, as may be necessary for the City to determine whether such user should be designated as Class IA, IB, IIA, IIB, III, IV, or V.

E. Industrial users must, if requested, provide such other information regarding the nature of the entity, its operations, storage and use of chemicals, and storage and use of hazardous substances, as may be reasonably necessary to make such determination as to the classification of said user and whether a wastewater discharge permit is needed. The City may also require information relating to potential for accidental discharges to a City facility of hazardous or prohibited substances. Such inquiries may include information regarding the current disposal procedures of the user with regard to chemicals and/or substances that are not in the ordinary course of the user's operations discharge to a City facility.

F. The City Manager, at his/her discretion, may use general wastewater discharge permits to control discharges to the POTW if all facilities to be covered by the general wastewater discharge permit meet all the following conditions:

(1) Involve the same or substantially similar types of operations;

(2) Discharge the same types of wastes;

(3) Require the same effluent limitations;

(4) Require the same or similar monitoring; and

(5) In the opinion of the City Manager, are more appropriately controlled under a general wastewater discharge permit than under an individual wastewater discharge permit.

G. To be covered under a general wastewater discharge permit, the user must file a written request for coverage that identifies its contact information, production processes, types of wastes generated, location for monitoring all wastes covered by the general wastewater discharge permit, any requests in accordance with Section 12.18.060.4(B) for a monitoring waiver for a pollutant neither present nor expected to be present in the discharge, and any other information the City Manager deems appropriate. A monitoring waiver for a pollutant neither present nor expected to be present in the discharge is not effective in the general wastewater discharge permit until after the City Manager has provided written notice to the user that such a waiver request has been granted in accordance with Section 12.18.060.4(B).

H. The City Manager will retain a copy of the general wastewater discharge permit, documentation to support the City's determination that a specific user meets the criteria of Section 12.18.040.6(A)(1) through (8) and applicable State regulations, and a copy of the user's written request for coverage for three (3) years after the expiration of the general wastewater discharge permit.

I. The City Manager may not control a user through a general wastewater discharge permit where the user is subject to production-based categorical pretreatment standards or categorical pretreatment standards expressed as a mass of pollutant discharged per day or for users whose limits are based on the combined wastestream formula (see Section 12.18.020.2(C)) (40 CFR Part 403.6(e)) or net/gross calculations (see Section 12.18.020.2(D)).

B. In its petition, the appealing party must indicate the wastewater discharge permit provision(s) objected to, the reasons for this objection, and the alternative conditions, if any, it seeks to place in the wastewater discharge permit.

C. The effectiveness of the wastewater discharge permit shall not be stayed pending appeal.

D. If the City Council fails to act within sixty (60) days, a request for reconsideration shall be deemed to be denied. Decisions not to reconsider a wastewater discharge permit, not to issue a wastewater discharge permit, or modify a wastewater discharge permit shall be considered final administrative actions for purpose of judicial review.

E. Aggrieved parties seeking judicial review of the final administrative wastewater discharge permit decision must do so by filing a complaint with the Superior Court of Contra Costa County within thirty (30) days.

A. The City Manager may modify an individual wastewater discharge permit for good cause, including, but not limited to, the following reasons:

(1) To incorporate any new or revised Federal, State, or local pretreatment standards or requirements;

(2) To address significant alterations or additions to the user's operation, processes, or wastewater volume or character since the time of the wastewater discharge permit issuance;

(3) A change in the POTW that requires either a temporary or permanent reduction or elimination of the authorized discharge;

(4) Information indicating that the permitted discharge poses a threat to the POTW, City personnel, or the receiving waters;

(5) Violation of any terms or conditions of the wastewater discharge permit;

(6) Misrepresentation or failure to fully disclose all relevant facts in the wastewater discharge permit application or in any required reporting;

(7) Revision of, or a grant of, variance from categorical pretreatment standards pursuant to 40 CFR Part 403.13;

(8) To correct typographical or other errors in the wastewater discharge permit; or

(9) To reflect a transfer of the user ownership or operation to a new owner or operator where requested in accordance with Section 12.18.050.5.

B. The City Manager may modify a general wastewater discharge permit for good cause, including, but not limited to, the following reasons:

(1) To incorporate any new or revised Federal, State, or local pretreatment standards or requirements;

(2) A change in the POTW that requires either a temporary or permanent reduction or elimination of the authorized discharge;

(3) To correct typographical or other errors in the wastewater discharge permit; or

(4) To reflect a transfer of user ownership or operation to a new owner or operator where requested in accordance with Section 12.18.050.5.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

An individual or general wastewater discharge permit may be transferred to a new owner or operator only if the permittee gives at least sixty (60) days advanced notice to the City Manager, and the City Manager approves the permit transfer. The notice to the City Manager must include a written certification by the new owner or operator which:

A. States that the new owner/operator has no immediate intent to change the user's operations and processes;

B. Identifies the specific date on which the transfer is to occur; and

C. Acknowledges full responsibility for complying with the existing wastewater discharge permit.

Failure to provide advance notice of a transfer renders a wastewater discharge permit void as of the date of the user transfer.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may revoke an individual or a general wastewater discharge permit for good cause, including, but not limited to, the following reasons:

A. Failure to notify the City Manager of significant changes to the wastewater prior to the changed discharge;

B. Failure to provide prior notification to the City Manager pursuant to Section 12.18.060.5 of this chapter;

C. Misrepresentation or failure to fully disclose all relevant facts in the wastewater discharge permit application;

D. Falsifying self-monitoring reports and certification statements;

E. Tampering with monitoring equipment;

F. Refusing to allow the City Manager timely access to the facility premises and records;

G. Failure to meet effluent limitations;

K. Failure to complete a wastewater survey or wastewater discharge permit application;

L. Failure to provide advance notice of the transfer of business ownership of a permitted user; or

M. Violation of any pretreatment standard or requirement, or any terms of a wastewater discharge permit, or this chapter.

Individual wastewater discharge permits shall be voidable upon cessation of operations or transfer of business ownership. All individual wastewater discharge permits issued to a user are void upon the issuance of a new individual wastewater discharge permit to that user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A user with an expiring individual or coverage under a general wastewater discharge permit shall apply for wastewater discharge permit reissuance by submitting a complete permit application, in accordance with Section 12.18.040.5 of this chapter, a minimum of ninety (90) days prior to the expiration of the user's existing wastewater discharge permit.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. If another jurisdiction, or user located within another jurisdiction, contributes wastewater to the POTW, the City Manager shall enter into an agreement with the contributing jurisdiction.

B. Prior to entering into an agreement as required by Section 12.18.050.8(A), the City Manager shall request the following information from the contributing jurisdiction:

(1) A description of the quality and volume of wastewater discharged to the POTW by the contributing jurisdiction;

(2) An inventory of all users located within the contributing jurisdiction that are discharging to the POTW; and

(3) Other such information that the City Manager deems necessary.

C. An intermunicipal agreement, as required by Section 12.18.050.8(A), shall contain the following conditions:

(1) A requirement for the contributing municipality to adopt a sewer use ordinance which is at least as stringent as this chapter and local limits, including baseline monitoring reports (BMRs) which are at least as stringent as those set out in Section 12.18.020.4 of this chapter. The requirement shall specify that such ordinance and limits must be revised as necessary to reflect changes made to the City's ordinance or local limits;

(2) A requirement for the contributing municipality to submit a revised user inventory on at least an annual basis;

(3) A provision specifying which pretreatment implementation activities, including wastewater discharge permit issuance, inspection and sampling, and enforcement, will be conducted by the contributing jurisdiction; which of these activities will be conducted by the City Manager; and which of these activities will be conducted jointly by the contributing jurisdiction and City Manager;

(4) A requirement for the contributing jurisdiction to provide the City Manager with access to all information that the contributing jurisdiction obtains as part of its pretreatment activities;

(5) Limits on the nature, quality, and volume of the contributing jurisdiction's wastewater at the point where it discharges to the POTW;

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users that become subject to new or revised categorical pretreatment standards are required to comply with the following reporting requirements even if they have been designated as non-significant categorical industrial users.

A. Within either one hundred eighty (180) days after the effect of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR Part 403.6(a)(4), whichever is later, existing categorical industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the City Manager a report which contains information listed in Section 12.18.060.1(B). At least ninety (90) days prior to commencement of their discharge, new sources, and sources that become categorical industrial users subsequent to the promulgation of an applicable categorical standard, shall submit to the City Manager a report which contains the information listed in Section 12.18.060.1(B). A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source shall also give estimates of its anticipated flow and quantity of pollutants to be discharged.

B. Users described above shall submit the information set forth below.

(1) All information required in Sections 12.18.040.5(A)(1)(a), 12.18.040.5(A)(2), 12.18.040.5(A)(3)(a), and 12.18.040.5(A)(6).

(2) Measurement of Pollutants.

(a) The user shall provide the information required in Section 12.18.040.5(A)(7)(a) through (d).

(b) The user shall take a minimum of one (1) representative sample to compile data necessary to comply with the requirements of this paragraph.

(c) Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewater are mixed with the regulated wastewater prior to pretreatment, the user should measure the flows and concentrations necessary to allow use of the combined wastestream formula in 40 CFR Part 403.6(e) to evaluate compliance with pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR Part 403.6(e), this adjusted limit along with supporting data shall be submitted to the City.

(d) Sampling and analysis shall be performed in accordance with Section 12.18.060.10.

(e) The City Manager may allow the submission of a baseline report which utilizes only historical data as long as the data provide information sufficient to determine the need for industrial pretreatment measures.

(f) The baseline report 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 to the POTW.

(3) Compliance Certification. A statement, reviewed by the user's authorized representative (as defined in Section 12.18.010.5(A)(5) and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance and/or additional pretreatment is required to meet pretreatment standards and requirements.

(4) Compliance Schedule. If additional pretreatment and/or operation and maintenance will be required to meet pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment and/or operation and maintenance must be provided. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule pursuant to this section must meet the requirements set out in Section 12.18.060.2 of this chapter.

(5) Signature and Report Certification. All baseline monitoring reports must be certified in accordance with Section 12.18.060.14(A) of this chapter and signed by an authorized representative (as defined in Section 12.18.010.5(A)(5)).

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The following conditions shall apply to the compliance schedule required by Section 12.18.060.1(B)(4) of this chapter.

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 user to the 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 (9) months;

C. The user shall submit a progress report to the City Manager no later than fourteen (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 (9) months elapse between such progress reports to the City Manager.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Within ninety (90) days following the date for final compliance with applicable categorical pretreatment standards, or in the case of a new source following commencement of the introduction of wastewater to the POTW, any user subject to such pretreatment standards and requirements shall submit to the City Manager a report containing the information described in Section 12.18.040.5(A)(1) through (7) and Section 12.18.060.1(B)(2) of this chapter. For users subject to equivalent mass or concentration limits established in accordance with the procedures in Section 12.18.020.2 (see 40 CFR 403.6(c)), this report shall contain a reasonable measure of the user's long-term production rate. For all other user subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period. All compliance reports must be signed and certified in accordance with Section 12.18.060.14(A) of this chapter. All sampling will be done in conformance with Section 12.18.060.11.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

All SIUs are required to submit periodic compliance reports even if they have been designated a non-significant categorical industrial user under the provisions of Section 12.18.060.4(C).

A. Except as specified in Section 12.18.060.4(C), all users must, at a frequency determined by the City Manager, submit no less than twice per year (July 31st and January 31st) reports indicating the nature, concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. In cases where the pretreatment standard requires compliance with a BMP or pollution prevention alternative, the user must submit documentation required by the City Manager or the pretreatment standard necessary to determine the compliance status of the user.

B. The City may authorize a user subject to a categorical pretreatment standard to forego sampling of a pollutant regulated by a categorical pretreatment standard if the user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is only present at background levels from intake water and without any increase in the pollutant due to activities of the user [see 40 CFR 403.12(e)(2)]. This authorization is subject to the following conditions:

(1) The waiver may be authorized where a pollutant is determined to be present solely due to sanitary wastewater being discharged from the facility provided that the sanitary wastewater is not regulated by an applicable categorical pretreatment standard and otherwise includes no process wastewater.

(2) The monitoring waiver is valid only for the duration for the effective period of the wastewater discharge permit, but in no case longer than five (5) years. The user must submit a new request for the waiver before the waiver can be granted for each subsequent wastewater discharge permit. (See Section 12.18.040.5(A)(8).)

(3) In making a demonstration that a pollutant is not present, the user must provide data from at least one (1) sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes.

(4) The request for a monitoring waiver must be signed in accordance with Section 12.18.010.5(A)(5), and include the certification statement in Section 12.18.060.14(A) [40 CFR 403.6(a)(2)(ii)].

(5) Non-detectable sample results may be used only as a demonstration that a pollutant is not present if the EPA-approved method from 40 CFR Part 136 with the lowest minimum detection level for that pollutant was used in the analysis.

(6) Any grant of a monitoring waiver by the City Manager must be included as a condition in the user's wastewater discharge permit. The reasons supporting the waiver and any information submitted by the user in its request for the waiver must be maintained by the City Manager for three (3) years after the expiration of the waiver.

(7) Upon approval of the monitoring waiver and revision to the user's wastewater discharge permit by the City Manager, the user must certify on each report with the certification statement in Section 12.18.060.14(C), that there has been no increase in the pollutant in its wastestream due to activities of the user.

(8) In the event that a waived pollutant is found to be present or expected to be present because of changes that occur in the user's operations, the user must immediately comply with the monitoring requirements of Section 12.18.060.4(A), or other more frequent monitoring requirements imposed by the City Manager, and notify the City Manager.

(9) This provision does not supersede certification processes and requirements established in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.

C. The City may reduce the requirement for periodic compliance reports (see Section 12.18.060.4(A)) [40 CFR Part 403.12(e)(1)] to a requirement to report no less frequently than once per year, unless required more frequently in the pretreatment standard or by EPA or the State, where the user's total categorical wastewater flow does not exceed any of the following:

(1) 0.01 percent (0.01%) of the design dry weather hydraulic capacity of the POTW, or five thousand (5,000) gpd, whichever is smaller, as measured by a continuous effluent flow monitoring device unless the user discharges in batches;

(2) 0.01 percent (0.01%) of the design dry weather organic treatment capacity of the POTW; and

(3) 0.01 percent (0.01%) of the maximum allowable headworks loading for any pollutant regulated by the applicable categorical pretreatment standard for which approved local limits were developed in accordance with Section 12.18.020.4 of this chapter.

Reduced reporting is not available to users that have in the last two (2) years been in significant noncompliance, as defined in Section 12.18.010.5(A)(81) of this chapter. In addition, reduced reporting is not available to a user with daily flow rates, production levels, or pollutant levels that vary so significantly that, in the opinion of the City Manager, decreasing the reporting requirement for this user would result in data that are not representative of conditions occurring during the reporting period.

D. All periodic compliance reports must be signed and certified in accordance with Section 12.18.060.14(A) of this chapter.

E. All wastewater samples must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of the user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.

F. If a user subject to the reporting requirement of this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the City Manager, using the procedures prescribed in Section 12.18.060.11 of this chapter, the results of this monitoring shall be included in the report.

G. Users that send electronic (digital) documents to the City to satisfy the requirements of this section must comply with the City's reporting requirements as specified per 40 CFR Part 3.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Each user must notify the City Manager of any significant changes to the user's operations or system which might alter the nature, quality, or volume of its wastewater at least sixty (60) days before the change.

A. The City Manager may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under Section 12.18.040.5 of this chapter.

B. The City Manager may issue an individual or a general wastewater discharge permit under Section 12.18.050.7 of this chapter or modify the existing wastewater discharge permit under Section 12.18.050.4 of this chapter in response to changed conditions or anticipated changed conditions.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. In cases of any discharge, including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify the City Manager 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 user.

B. Within five (5) days following such discharge, the user shall, unless waived by the City Manager, 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 user of any expense, loss, damage, or other liability which might 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 user of any fines, penalties, or other liability which may be imposed pursuant to this chapter.

C. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in Section 12.18.060.6(A). Employers shall ensure that all employees, who could cause such a discharge to occur, are advised of the emergency notification procedure.

D. SIUs are required to notify the City Manager immediately of any changes at its facility affecting the potential for a slug discharge.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users not required to obtain a wastewater discharge permit shall provide appropriate reports to the City Manager as he/she may require.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

If sampling performed by a user indicates a violation, the user must notify the City Manager within twenty-four (24) hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the City Manager within thirty (30) days after becoming aware of the violation. Resampling by the user is not required if the City performs sampling at the user's facility at least once per month, or if the City performs sampling at the user's facility between the time when the initial sampling was conducted and the time when the user or the City receives the results of this sampling, or if the City has performed the sampling and analysis in lieu of the user.

As a result of any discharge violation, increased sampling and inspections may be required to verify that the violation has been corrected. The magnitude of the violation will dictate how many follow-up samples and inspections will be conducted to verify that the violation has been corrected. For violations in the NOV range, the following minimum sampling schedule will be established: one follow-up sample will be taken within thirty (30) days by the user and/or the City. Monthly monitoring will continue at the facility until at least three (3) consecutive sample results, over a three-month period (minimum), indicate the discharge is no longer in violation.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. Any user who commences discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and Department of Toxic Substances Control, in writing, of any discharge to the POTW of a substance, which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification shall also contain the following information to the extent that such information is known and readily available to the user:

(1) An identification of the hazardous constituents contained in the wastes;

(2) An estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month; and

(3) An estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months.

All notifications must take place no later than one hundred and eighty (180) days after the discharge commences. Any notification under this paragraph needs to be submitted only once for each hazardous waste discharged. However, notifications of changed conditions must be submitted under Section 12.18.060.5 of this chapter. The notification requirement of this section does not apply to pollutants already reported by the users subject to categorical pretreatment standards under the self-monitoring requirements of Sections 12.18.060.1, 12.18.060.3, and 12.18.060.4 of this chapter.

B. In the case of any new regulations under Section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substances as a hazardous waste, the user must notify the City Manager, the EPA Regional Waste Management Division Director, and Department of Toxic Substances Control of the discharge of such substance within ninety (90) days of the effective date of such regulations.

C. In the case of any notification made under this section, the 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.

D. This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this chapter, a wastewater discharge permit issued thereunder, or any applicable Federal or State law.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

All pollutant analyses, including sampling techniques, to be submitted as part of the wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where EPA determines that the Part 136 sampling and analysis are inappropriate for the pollutant in question, sampling and analyses shall be performed by using validated analytical methods for any other applicable sampling and analytical procedures, including procedures suggested by the City Manager or other parties approved by EPA.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Samples collected to satisfy reporting requirements must be based on data obtained through appropriate sampling and analysis performed during the period covered by the report, based on the data that is representative of conditions occurring during the reporting period.

A. Except as indicated in Section 12.18.060.11(B) through (C), the user must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the City Manager. Where time-proportional composite sampling or grab sampling is authorized by the City, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the City, as appropriate. In addition, grab samples may be required to show compliance with instantaneous limits.

B. Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.

C. For sampling required in support of baseline monitoring and 90-day compliance reports required in Sections 12.18.060.1 and 12.18.060.3, a minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds for facilities for which historical sampling data do not exist; for facilities for which historical sampling data are available, the City Manager may authorize a lower minimum. For the reports required in Section 12.18.060.4, the user is required to collect the number of grab samples necessary to assess and assure compliance with applicable pretreatment standards and requirements.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Written reports will be deemed to have been submitted on the date postmarked. For reports, which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users subject to the reporting requirements of this chapter shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this chapter, any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements, and documentation associated with BMPs established under Section 12.18.020.4(D). Records shall include the date, exact place, method and time of sampling, and the name of the person(s) taking the samples; the date(s) analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the user or the City, or where the user has been specifically notified of a longer retention period by the City Manager.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

An authorized inspector or the City Manager shall have the right to enter the premises of any user to determine whether the user is complying with all requirements of this chapter and any wastewater discharge permit or order issued hereunder. Users shall allow the authorized inspector or City Manager ready access to all parts of the premises for the purposes of inspection, sampling, records examination and copying, and the performance of any additional duties.

A. Where a user has security measures in force which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the authorized inspector or City Manager shall be permitted to enter without delay for the purposes of performing specific responsibilities.

B. The authorized inspector or City Manager shall have the right to set up on the user's premises, or require installation of, such devices as are necessary to conduct sampling and/or metering of the user's operations.

C. The City Manager may require the user to install monitoring equipment as necessary. The user's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the user at its own expense. All devices used to measure wastewater flow and quality shall be calibrated according to manufacturer's specifications to ensure their accuracy.

D. Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the user at the written notice or verbal request of the City Manager and shall not be replaced. The costs of clearing such access shall be borne by the user.

E. Unreasonable delays in allowing the authorized inspector or City Manager access to the user's premises shall be a violation of this chapter.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

If an authorized inspector or City Manager has been refused access to a building, structure, or property, or any part thereof, and is able to demonstrate probable cause to believe there may be a violation of this chapter, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program of the City designed to verify compliance with this chapter or any permit or order issued hereunder, or to protect overall public health, safety, and welfare of the community, the City may seek issuance of a search warrant from the Contra Costa County Superior Court.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Information and data on a user obtained from reports, surveys, wastewater discharge permit applications, wastewater discharge permits, and monitoring programs, and from inspection and sampling activities, shall be available to the public without restriction, unless the user specifically requests, and is able to demonstrate to the satisfaction of the City Manager, that the release of such information would divulge information, processes, or methods of production entitled to protection as trade secrets under applicable State law. Any such request must be asserted at the time of submission of the information or data. When requested and demonstrated by the user furnishing a report that such information should be held confidential, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available immediately upon request to governmental agencies for uses related to the NPDES program or pretreatment program, and in enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics and other effluent data as defined in 40 CFR Part 2.302 shall not be recognized as confidential information and shall be available to the public without restriction.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City shall publish annually, in a newspaper of general circulation that provides meaningful public notice within the jurisdictions served by the POTW, a list of users which, at any time during the previous twelve (12) months, were in significant noncompliance with applicable pretreatment standards and requirements. The term significant noncompliance shall be applicable to all SIUs (or any other user that violates subsection (C), (D), or (H) of this section) and shall mean the following:

A. Chronic violations of wastewater discharge limits, defined here as those in which sixty-six percent (66%) or more of all measurements taken for the same pollutant parameter during a six- (6-) month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits as defined in Section 12.18.020;

B. Technical review criteria (TRC) violations, defined here as those in which thirty-three percent (33%) or more of wastewater measurements taken for each pollutant parameter during a six- (6-) month period equals or exceeds the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined in Section 12.18.020 multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils, and grease, and 1.2 for all other pollutants except pH);

C. Any other violation of a pretreatment standard or requirement as defined by Section 12.18.020 (daily maximum, long-term average, instantaneous limit, or narrative standard) that the City Manager determines has caused, alone or in combination with other discharges, interference, or pass through, including endangering the health of the POTW personnel or the general public;

D. Any discharge of a pollutant that has caused imminent endangerment to the public or the environment, or has resulted in the City Manager's exercise of its emergency authority to halt or prevent such a discharge;

E. Failure to meet, within ninety (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;

F. Failure to provide within forty-five (45) days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, period self-monitoring reports, and reports on compliance with compliance schedules;

G. Failure to accurately report noncompliance; or

H. Any other violation(s), which may include a violation of best management practices, which the City Manager determines will adversely affect the operation or implementation of the pretreatment program.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

It is the intent of this enforcement section to provide adequate mechanisms to achieve a maximum degree of compliance with this chapter by all users. These enforcement provisions apply to all classes of users to the extent such user violates any provision of this chapter or administrative order of the City pursuant to this chapter. In order to achieve the maximum degree of compliance desired, the City will use a variety of enforcement mechanisms. The enforcement mechanisms set forth range from informal administrative action to formal criminal prosecution. The City may, in its discretion, implement the use of any mechanism or the concurrent use of several mechanisms in order to enforce the provisions of this chapter. The enforcement mechanisms provided herein may be cumulative in respect to such other enforcement mechanisms or civil and criminal penalties as may be otherwise available under the laws of the State of California and the United States of America. Nothing in this chapter is intended to prevent State and/or Federal regulatory agencies from undertaking enforcement actions as may otherwise be available due to a violation of this chapter which also constitutes a violation of Federal or State statutes and regulations, such as: (1) the Clean Water Act (33 USCA § 1251 et seq.); (2) the California Porter-Cologne Water Quality Act (California Water Code § 13000 et seq.); (3) the California Hazardous Waste Control Law (California Health and Safety Code §§ 25100—25250); (4) the Resource Conservation and Recovery Act (42 USCA § 6901 et seq.); and (5) California Government Code §§ 54739—54740.6. The referenced State and Federal laws, along with other pertinent laws, provide authority for the City's enforcement mechanisms.

The enforcement mechanisms available to the City for violations of the provisions of this chapter, applicable City resolutions, and permit or permit contract provisions include the following:

A. Informal administrative actions.

(1) Letter of warning.

(2) Notice of violation.

B. Compliance meeting.

C. Consent orders.

D. Assessment of charges for obstruction or damage to POTW or operations.

E. Show cause hearings.

F. Compliance order.

G. Cease and desist order.

H. Emergency suspension.

I. Termination of service or revocation of wastewater discharge permit.

J. Administrative fines.

K. Enforcement of the FOG Program.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

City staff may, on an informal basis, take action against a discharger for minor violations or technical or clerical shortcomings of a user or a user's compliance submittals. These informal administrative actions may include informal notices (i.e., telephone calls to the user's representative), a notice of violation (NOV), and informal meetings or informal warning letters. These informal administrative actions may establish a compliance schedule for the discharger to follow in order to document compliance. Such action will not prevent a subsequent or concurrent imposition of other enforcement mechanisms.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A letter of warning is generally issued for an isolated non-significant violation. In this case, the inspector notifies the user (in writing) that a violation occurred and directs the user to take corrective actions. This notification serves as the enforcement action. The letter of warning will be placed in the City's file. The inspector may schedule additional inspections and/or sampling, or may elect to implement more stringent enforcement action.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

When the City Manager finds that a 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 City Manager may serve upon that user a written notice of violation. Within fourteen (14) days of the receipt of such notice, an explanation of the violation and a plan for the satisfactory correction and prevention thereof, to include specific required actions, shall be submitted by the user to the City Manager. Submission of such a plan in no way relieves the user of liability for any violations occurring before or after receipt of the notice of violation. Nothing in this section shall limit the authority of the City Manager to take any action, including emergency actions or any other enforcement actions, without first issuing a notice of violation.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Compliance meetings are held when severe violations occur or when previous violations appear to remain uncorrected as evidenced by repeated violations. Many NOVs do not require a compliance meeting. The enforcement response guide details when compliance meetings are required. During a compliance meeting, a compliance schedule and timeline are established for the user to correct the violation. Progress on the compliance schedule is tracked by the inspector and reported to the Environmental Services Manager. Compliance schedules are fulfilled when all tasks are completed and consistent compliance is achieved. The wastewater discharge permit may be modified to include the provisions of a compliance schedule.

A. A compliance meeting is generally scheduled when:

(1) The user exceeds five (5) times the applicable discharge limit for any toxic pollutant or violates any California State Hazardous Waste Limit.

(2) The user has a pH violation of less than two (2) or greater than twelve (12) or has two NOVs in a two-month period.

(3) The user has demonstrated a pattern of noncompliance. A pattern of noncompliance would include:

(a) The user has been listed in accordance with the Regional Water Quality Control Board (Regional Water Board) Standard Provisions (1991) as inconsistently achieving compliance or as having significantly violated applicable pretreatment requirements for two consecutive quarters for the same pollutant;

(b) A user has four (4) or more NOVs in a five- (5-) month period for any sewer use ordinance violation; or

(c) Failure to respond to an NOV within forty-five (45) days of the due date.

B. A maximum of two (2) compliance meetings per pollutant, within a two- (2) year period, may be held to address noncompliance before more stringent enforcement actions are considered. In cases of severe noncompliance, or when the user has already had two (2) previous compliance meetings, the wastewater discharge permit may be modified to include the provisions of a compliance schedule.

C. Violations which occur during the implementation of a compliance schedule, and which involve the pollutant(s) addressed by the compliance schedule, may be documented through enforcement actions of a lesser degree than indicated in the enforcement response guide, if short-term measures have been implemented to prevent violations. If a user is under a compliance schedule and receives an enforcement action less than what is called for in the procedures, the inspector must write the following on the enforcement action approval form:

(1) That the enforcement action is less severe than the procedural requirement because the user is under a compliance schedule; and

(2) Reference the specific compliance meeting.

This process allows for the documentation of all violations without excessively penalizing a user who is actively working to correct the violation.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

When a user's discharge, whether due to negligence, accident, spill, or otherwise, causes an obstruction, damage, or any other impairment to the City's operation or facilities, the City may impose a charge on the user for the cost to clean or repair the facility, or costs incurred to resume normal operations. An administrative service fee of twenty-five percent (25%) of the City's costs may be added to these charges. The total amount shall be paid within forty-five (45) days of invoicing by the City. If it can be shown that the user's discharge caused or significantly contributed to the City violating its discharge requirements or incurring additional expenses or suffering loss or damage to the operation or facilities, then the user shall be responsible for any costs or expenses, or a prorated portion of such expenses, including assessments or penalties imposed by other agencies or the court on the City.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may enter into consent orders, assurances of compliance, or other similar documents establishing an agreement with any user responsible for noncompliance. Such documents shall include specific action to be taken by the user to correct the noncompliance within a time period specified by the document. Such documents shall have the same force and effect as the administrative orders issued pursuant to Sections 12.18.100.8 and 12.18.100.9 of this chapter and shall be judicially enforceable.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may order the user which has violated, or continues to violate, any provision of this chapter, wastewater discharge permit, or order issued hereunder, or any other pretreatment standards or requirement, to appear before the City Manager and show cause why the proposed enforcement action should not be taken. Notice shall be served on the user specifying the time and place of 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. This notice of the meeting shall be served personally or by registered or certified mail (return receipt requested) at least fourteen (14) days prior to the hearing. Such notice may be served on any Authorized Representative of the user (as defined in Section 12.18.010.5(A)(5) and required by Section 12.18.040.7(A)). A show cause hearing shall not be a bar against, or prerequisite for, taking any other action against the user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

When the City Manager finds that a user has violated, or continues to violate, any provision of this chapter, wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the City Manager may issue an order to the user responsible for the discharge directing that the user comes into compliance within a specified time. If the user does not come into compliance within the time provided, sewer service may be discontinued unless adequate treatment facilities, devices, or other related appurtenances are installed and properly operated. Compliance orders also may contain other requirements to address the noncompliance, including additional self-monitoring and BMPs designed to minimize the amount of pollutants discharged to the sewer. A compliance order may not extend the deadline for compliance established for a pretreatment standard or requirement, nor does a compliance order relieve the user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a bar against, or a prerequisite for, taking any other action against the user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

When the City Manager finds that a 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 City Manager may issue an order to the user directing it to cease and desist all such violations and directing the user to:

A. Immediately comply with all requirements; and

B. Take such appropriate remedial or preventative 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 user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may immediately suspend a user's discharge, after informal notice to the user, whenever such suspension is necessary to stop an actual or threatened discharge, which reasonably appears to present, or cause an imminent or substantial endangerment to the health or welfare of persons. The City Manager may also immediately suspend a user's discharge after notice and opportunity to respond, that threatens to interfere with the operation of the POTW, or which presents, or may present, an endangerment to the environment.

A. Any user notified of a suspension of its discharge shall immediately stop or eliminate its contribution. In the event of a user's failure to immediately comply voluntarily with the suspension order, the City Manager may take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The City Manager may allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the City Manager that the period of endangerment has passed, unless the termination proceedings in Section 12.18.100.11 of this chapter are initiated against the user.

B. A 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, to the City Manager prior to the date of any show cause or termination hearing under Section 12.18.100.7 or 12.18.100.11 of this chapter.

Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this section.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

In addition to provisions in Section 12.18.050.6 of this chapter, any user who violates the following conditions is subject to discharge termination:

A. Violation of wastewater discharge permit conditions;

B. Failure to accurately report wastewater constituents and characteristics of its discharge;

C. Failure to report significant changes in operations or wastewater volume, constituents, and characteristics prior to discharge;

D. Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring, or sampling; or

E. Violation of pretreatment standards in Section 12.18.020 of this chapter.

Such user will be notified of the proposed termination of its discharge and offered an opportunity to show cause under Section 12.18.100.7 of this chapter why the proposed action should not be taken. Exercise of this option by the City Manager shall not be a bar to, or a prerequisite for, taking any other action against the user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. Pursuant to the authority of California Government Code Sections 54739 to 54740.6, the City or City staff may issue administrative complaints, conduct administrative hearings, and/or impose civil penalties in accordance with the procedures set forth in these sections for violation of the City's requirements relating to pretreatment of industrial waste or the prevention of the entry of industrial waste into the City's collection system or treatment works. These penalties shall be as follows:

(1) In an amount which shall not exceed two thousand dollars ($2,000) for each day for failing or refusing to furnish technical or monitoring reports.

(2) In an amount which shall not exceed three thousand dollars ($3,000) for each day for failing or refusing to timely comply with any compliance schedule established by the City.

(3) In an amount which shall not exceed five thousand dollars ($5,000) per violation for each day for discharges in violation of any waste discharge limitation, permit condition, or requirement issued, reissued, or adopted by the City.

(4) In an amount which does not exceed ten dollars ($10) per gallon for discharges in violation of any suspension, cease and desist order, or other orders, or prohibition issued, reissued, or adopted by the City.

B. Unless appealed, orders setting administrative civil penalties shall become effective and final upon issuance thereof, and payment shall be made within thirty (30) days.

C. As to court actions authorized by the above-referenced sections, the City Attorney, or other special counsel designated by the City Attorney, shall institute appropriate actions to effect statutorily authorized remedies, upon order of the City Council.

D. Unpaid charges, fines, and penalties shall, after thirty (30) calendar days, be assessed an additional penalty of ten percent (10%) of the unpaid balance. A lien against the user's property shall be sought for unpaid charges, fines, and penalties.

E. Users desiring to dispute such fines must file a written request for the City Manager to reconsider the fine along with full payment of the fine amount within thirty (30) days of being notified of the fine. The City Manager shall convene a hearing on the matter within ten (10) days. In the event the user's appeal is successful, the payment, together with any additional penalty assessed thereto, shall be returned to the user. The City Manager may add the costs of preparing administrative enforcement actions, such as notices and orders, to the fine.

F. Issuance of an administrative fine shall not be a bar against, or a prerequisite for, taking any other action against the user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

In the event that a user fails to comply with the City requirements pursuant to Section 12.18.030.2, the City may take the following enforcement actions until the user complies with such requirements to prevent FOG from entering the City collection system:

A. Issuance of a Notice of Violation when a user fails to comply with Section 12.18.030.2(A), (B), (C), (D) and/or (F) during an initial inspection.

B. Issuance of an administrative fine when a user fails to comply with Section 12.18.030.2(A), (B), (C), (D) and/or (F) during two consecutive inspections.

(1) Administrative citation fines are as follows: $250 for the first citation, $500 for the second citation; and $1,000 for the third citation.

(2) Administrative citation fines shall escalate if the same violation occurs within 365 days.

(3) The City may apply such administrative citation fines to domestic users if there is sufficient evidence to show FOG is contributed to the City collection system from the users' private lateral connection repeatedly, and the user fails to implement best management practices as set forth by the City Manager or his designees.

(4) Appeal of Administrative citation fines shall follow procedures as described in Section 12.18.100.12(B), (C), (D), (E).

(Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

In the event that a user fails to comply with City-initiated enforcement actions, the City may seek judicial remedies, including, but not limited to, injunctive relief, civil penalties, and criminal prosecution, through the City Attorney. For case referrals, the City Attorney is consulted and is the lead agent in developing the referral document.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

When the City Manager finds that a 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 City Manager may petition the Contra Costa County Superior Court through the City Attorney for issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, or other requirement imposed by this chapter on activities of the user. The City Manager may also seek other action as appropriate for legal and/or equitable relief, including a requirement for the 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 user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Council may direct the City Attorney or other special counsel to bring such civil actions as may be available at law or in equity in any court of competent jurisdiction to enforce the provisions of this chapter and to recover such charges, fees, penalties, and/or damages as may be assessed or may be incurred under the provisions of this chapter.

A. Whenever a discharge of wastewater is in violation of the provisions of this chapter, the City may petition the Superior Court for issuance of preliminary or permanent injunction, or both, as may be appropriate in restraining the continuance of such discharge.

B. Civic Actions for Penalties. Any user who violates any provision of this chapter, permit condition or permit contract condition, or who violates any cease and desist order prohibition, or effluent limitation, shall be liable civilly for a penalty not to exceed twenty-five thousand dollars ($25,000) for each day in which such violation occurs pursuant to California Government Code Section 54740. Pursuant to the authority of the Clean Water Act, 33 USCA, Section 1251 et seq. Any user committing a violation of any provision of this chapter, which is also a violation of pretreatment standard, effluent standard, or limitation or other applicable provision of the Clean Water Act shall be liable civilly for a sum not to exceed twenty-five thousand ($25,000) per violation for each day in which such violation occurs. The City Attorney, or other special counsel designated by the City Council, upon order of the City Council, shall institute such actions as may appropriate in the appropriate court to impose, assess and recover such sums.

C. Other Civil Actions. The City may require compliance with permit conditions or limitations by issuing administrative orders, including cease and desist orders and compliance schedules. Said orders are enforceable in a California court of general jurisdiction. The City, however, may directly undertake any court action for penalties without first seeking an administrative order or making use of a compliance schedule, and it may concurrently undertake such administrative and court actions as deemed appropriate.

D. In determining the amount of civil liability, the Court shall take into account all relevant circumstances, including, but not limited to, the extent of harm caused by the violation, the magnitude and duration of the violation, any economic benefit gained through the user's violation, corrective actions by the user, the compliance history of the user, and any other factor as justice requires.

E. Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, taking any other action against a user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

This penalty shall be in addition to any other cause of action for personal injury or property damage available under State law.

C. A user who knowingly makes false statements, representations, or certifications in any application, record, report, plan, or documentation filed, or required to be maintained, pursuant to this chapter, a wastewater discharge permit, or order issued hereunder, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method under this chapter shall, upon conviction, be punished by a fine and/or imprisonment in accordance with Section 1.04.100 of the City of Richmond Municipal Code.

D. In the event of a second conviction, a user shall be punished by a fine and/or imprisonment in accordance with Section 1.04.100 of the City of Richmond Municipal Code.

The remedies provided for this chapter are not exclusive. The City Manager may take any, all, or any combination of these actions against a noncompliant user. Enforcement for pretreatment violations will generally be in accordance with the City's enforcement response plan. However, the City Manager may take other action against any user when the circumstances warrant. Further, the City Manager is empowered to make more than one enforcement action against any noncompliant user.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A penalty may be assessed to any user for each day that a report required by this chapter, a permit or order issued hereunder is late, beginning five (5) days after the date the report is due. Higher penalties may also be assessed where reports are more than thirty (30) to forty-five (45) days late. Actions taken by the City Manager to collect late reporting penalties shall not limit his/her authority to initiate other enforcement actions that may include penalties for late reporting violations.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may decline to issue or reissue an individual or a general wastewater discharge permit to any user who has failed to comply with any provision of this chapter, a previous wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, unless such user first files a satisfactory bond, payable to the City of Richmond, in a sum not to exceed a value determined by the City Manager to be necessary to achieve compliance.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

The City Manager may decline to issue or reissue an individual or a general wastewater discharge permit to any user who has failed to comply with any provision of this chapter, a previous wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, unless the user first submits proof that it has obtained financial assurances sufficient to restore or repair damage to the POTW caused by its discharge.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Whenever a user has violated or continues to violate any provision of this chapter, an individual or general wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, water service to the user may be severed. Service will recommence, at the user's expense, only after the user has satisfactorily demonstrated its ability to comply.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

Users which have not achieved compliance with applicable pretreatment standards and requirements are not eligible to receive a contractual award for the sale of goods or services to the City. Existing contracts for the sale of goods and services to the City held by a user found to be in significant noncompliance with pretreatment standards or requirements may be terminated at the discretion of the City Manager.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. For the purposes of this section, 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 treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation.

B. An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the requirements of Section 12.18.130.1 C. are met.

C. A 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 in compliance with applicable operation and maintenance procedures; and

(3) The user has submitted the following information to the City Manager within twenty-four (24) hours of becoming aware of the upset (if this information is provided orally, a written submission must be provided within five (5) days):

(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 of noncompliance is expected to continue; and

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

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

E. Users shall have the opportunity for judicial determination of any claim of upset only in an enforcement action is brought for noncompliance with categorical pretreatment standards.

F. Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost, or fails.

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibitions in Section 12.18.020.1(A) of this chapter or the specific prohibitions in Sections 12.18.020.1(B)(3) through (7) and 12.18.020.1(B)(9) through (18) if it can 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 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 user's prior discharge when the City 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. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

A. For the purposes of this section:

(1) "Bypass" means the intentional diversion of wastestream from any portion of a user's treatment facility.

(2) 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 user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it is also for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Section 12.18.130.3(C) through (D).

C. Bypass Notifications.

(1) If a user knows in advance of the need for a bypass, it shall submit prior notice to the City Manager, at least ten (10) days before the date of the bypass, if possible.

(2) A user shall submit oral notice to the City Manager of an unanticipated bypass that exceeds applicable pretreatment standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (5) days of the time the user becomes aware of the bypass. The written submission shall contain the following information:

(a) A description of the bypass and its cause;

(b) The duration of the bypass, including exact dates and times;

(c) If the bypass has not been corrected, the anticipated time it is expected to continue; and

(d) The steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass.

The City Manager may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours.

D. Bypass.

(1) Bypass is prohibited, and the City Manager may take enforcement action against a user for a bypass, unless:

(a) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(b) 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 preventative maintenance; and

(c) The user submitted notices as required in Section 12.18.130.3(C).

(2) The City Manager may approve an anticipated bypass, after considering its adverse effects, if he/she determines that it will meet the three conditions listed in Section 12.18.130.3(D)(1)(a) through (c).

(Ord. No. 21-14 N.S., § I, 11-18-2014; Ord. No. 09-18, § I, 5-1-2018; Ord. No. 22-18 N.S., § I, 7-17-2018)

(b) If not corrected, then administrative orders will be issued;

(c) The penalties to be imposed shall be $250 for the first violation, $500 for the second violation, and $1,000 for the third violation and each violation thereafter;

K. Reserved.

L. Blockages determined to be caused by FOG and associated with a responsible party with evidence (i.e., televised recording of the source lateral), shall pay the City for the costs incurred pursuant to Section 12.18.100.5;

M. All fees, charges, and penalties, are due by the property owner;
