§ 14.17.070 — Sector control programs

14.17.070 - Sector control programs.

(A) General requirements. (1) Authority. The City may establish specific sector control programs for industrial users to control specific pollutants as necessary to meet the objectives of this Chapter. Pollutants subject to these sector control programs shall generally be controlled using best management practices (BMPs). The Director may implement these sector control programs through an industrial wastewater discharge permit, by letter, by an authorization to discharge, by other control mechanisms, or by directly enforcing this Chapter. All industrial users that are covered by these sector control programs shall comply with this Section, whether or not specifically notified by the City to do so. (2) Notification requirements and city review. The City will review new construction and existing facilities undergoing any physical change that requires a building permit; any change in ownership (regardless of how the change came to the City's attention); any change in operations; or any other change that could alter the nature, properties, or volume of wastewater discharge, to ensure that current sector control program requirements are implemented and the facility is in compliance. In connection with such review, the City may require appropriate measures to insure compliance, including without limitation the installation of one or more appropriate pretreatment devices, such as an interceptor. An industrial user shall inform the Director prior to any: (a) Sale or transfer of ownership of the business, including a written description (including capacity, model and manufacturer) of any and all interceptors currently installed and then-current interceptor BMPs; (b) Change in the trade name under which the business is operated; (c) Change in the nature of the services provided that affect the potential to discharge sector control program pollutants; or (d) Remodeling of the facility that may result in an increase in flow or pollutant loading or that otherwise requires the facility to submit plans or specifications for approval through a local building or zoning department, or for any other formal local approval process. (3) Inspections. (a) The Director may conduct inspections of any facility of an industrial user with or without notice for determining applicability of or compliance with sector control programs. (b) If any inspection reveals noncompliance with any sector control program requirement, corrective action shall be required. (c) Inspection results will be provided in writing to a facility upon request. (4) Closure. With respect to any facility of an industrial user, the Director may require closure of plumbing, treatment devices, storage components, containments, or other such physical structures that are no longer required for their intended purpose. Closure may include the removal of equipment, or the filling in or cementing, capping, plugging, etc., of facilities, or any combination thereof. (5) Enforcement and compliance. (a) Sector control program requirements established pursuant to this Section shall be deemed to be part of this Chapter, and their enforcement governed by the express terms of this Chapter. (b) Any extraordinary costs incurred by the City due to interference, damage, pass through, or maintenance necessary in the wastewater collection system or wastewater treatment system (or both) shall be paid by the industrial user to the City. The direct costs of all labor, equipment and materials incurred in rectifying the interference or damage, including reasonable attorney's fees, shall be billed directly to the owner or the industrial user by the City, and such costs shall become part of the total charges due and owing to the City and shall constitute a lien on the property associated with the costs until paid in full in accordance with pursuant to Section 14.17.090. (B) Best management practices for fats, oil and grease (FOG) facilities. (1) Definitions. For purposes of this subsection (B) and parallel references within this Chapter: "Fats, oil and grease" or "FOG" means non-petroleum organic polar compounds derived from animal or plant sources such as fats, non-hydrocarbons, fatty acids, soaps, waxes, and oils that contain multiple carbon chain triglyceride molecules. These substances are detectable and measurable using the approved method for Hexane Extractable Materials in the analytical procedures established in 40 CFR Part 136. "Gravity grease interceptor" or "GGI' means an in-ground tank containing at least one baffle in which solids, greases and oils are separated from wastewater, located outside an industrial user's building and made accessible for maintenance and inspections. "Hydromechanical grease interceptor" or "HMGI" means a small device hooked directly to the outgoing drains of sinks located inside a commercial food preparation facility that allows for the separation of fats, oils and grease of a non-petroleum nature from wastewater prior to being discharged into the POTW. (2) Applicability. These BMPs establish requirements for any facility that the Director determines that has the potential to discharge floatable or settleable material. The requirements established in this BMP shall apply to facilities where preparation, manufacturing, processing of food or washing/sanitizing of dishes or equipment occurs. Trucks containing mobile kitchens shall discharge their grease containing wastewater to a discharge point that has a GGI, such as a commissary or as otherwise required by the Director. Each facility that the Directory determines has the potential to discharge floatable or settleable material shall install and maintain a GGI within ninety days after being notified of such requirement. (3) No food-related facility covered by subsection (2) above shall discharge or cause to be discharged any wastewater containing free or floating oil and grease, or any discharge containing animal fat or grease by-product in excess of two hundred fifty milligrams per liter. Unless otherwise approved by the Director, such food-related facility shall install and properly operate and maintain a GGI, implement all required BMPs and not violate any general or specific prohibition described in Section 14.17.015. (4) A GGI or HMGI that was legally and properly installed at an industrial user's facility prior to the effective date of this Chapter and that does not comply with the requirements of this Chapter shall be acceptable as an alternative if such device is effective in removing floatable and settleable material and is designed and installed in such a manner that it can be inspected and properly maintained. If the Director determines at any time that such a GGI or HMGI is incapable of adequately retaining or capturing the floatable and settleable material, that it was installed in such a manner that it cannot be inspected and properly maintained, the industrial user shall install a GGI or HMGI that complies with all applicable City plumbing codes within ninety days after being notified of such requirement. (5) Variance. (a) A variance of the requirement to install a GGI or HMGI may be granted by the Director for good cause. An industrial user seeking a variance has the burden of demonstrating through data and other information why a variance should be granted. In no case shall a variance result in the violation of any pretreatment standard or requirement that is specified in this Chapter and applicable to the discharge. The granting of any variance shall be at the sole discretion of the Director and may be revoked at the Director's discretion. (b) If a variance is granted, the facility shall institute BMPs and other mitigation measures as specified by the Director. These BMPs may include, but are not limited to, the following: (i) Allowing the installation of a properly sized HMGI, or continuing to allow the use of an HMGI, in lieu of installing a GGI, where the HMGI is shown to be effective. If an HMGI is not shown to be effective, the Director may require the industrial user to install a GGI. (ii) Equipping all sinks and drains connected to the wastewater collection system with an approved strainer or grate that is removable and accessible and that will catch garbage and food debris and prevent it from entering the waste collection system. (iii) Prohibiting food grinders, unless the industrial user installs and properly operates a solids separator prior to discharging to the POTW. (iv) Prohibiting the use of biological or enzyme treatment unless approved by the Director, but in no case permitting the use of enzymes or other chemical or biological treatments or products that emulsify or act to emulsify FOG. (v) Instituting an employee training program regarding FOG waste management, to be provided to all new employees and to other employees on a periodic basis. (vi) Providing for quarterly cleaning of its private service line to prevent the buildup of oil, grease and solids, or as otherwise specified by the Director. (vii) Submitting records of private service line cleaning as specified by the Director. (viii) Paying costs incurred by the City or another jurisdiction for accelerated cleaning of the sewer line providing service between the facility and the POTW, as well as for costs incurred by the City treating excess strength waste and for sampling and analysis. (6) General control requirements. (a) A GGI or HMGI shall be required for the proper handling of liquid wastes which may be harmful to, or cause obstruction in the wastewater collection system or cause or contribute to pass through or interference with respect to the wastewater treatment system. (b) It shall be the responsibility of the industrial user or the owner of the property, or both, to contact the City's building and safety function in order to obtain any necessary permits for the installation of any interceptor or any modifications to the facility's plumbing. Written approval from the City must be obtained prior to installation of any interceptor. The timing of review and approval of such permits shall in no way relieve the industrial user of its responsibility to produce discharges acceptable to the City under the provisions of this Chapter. (c) The design and sizing of interceptors shall be in accordance with the edition of the Uniform Plumbing Code most recently adopted by the City, together with local City amendments to that Code. The preceding sentence applies whether the industrial user's facility is located in the City or another jurisdiction. An interceptor shall be designed, sized, installed, maintained and operated to accomplish the intended purpose of intercepting pollutants from the industrial user's wastewater and preventing the discharge of such pollutants to the City's wastewater collection and treatment systems, including pollutants that result in toxic, noxious or malodorous conditions that create a public nuisance or unsafe working conditions, which endanger life or the environment. (d) All sinks which are connected to an interceptor shall be equipped with an approved strainer or grate that is removable and accessible and that will catch garbage and food debris and prevent it from entering the interceptor. Food grinders are prohibited unless the industrial user installs and properly operates a solids separator captures and removed all waste product prior to its entry to an interceptor. (e) An industrial user must ensure that interceptors are accessible and unobstructed to allow for inspection, cleaning, and removal of FOG. (f) An industrial user must always maintain interceptors at its expense and keep them in efficient operating condition by the regular removal of accumulated FOG. All grease interceptors shall be completely pumped out, including all solids, liquid and grease. No pumped-out waste shall be re-introduced. (g) Each industrial user that is required to use and maintain a grease interceptor shall keep a record of every time the interceptor is pumped, cleaned or repaired. This record shall include the date, the name of the company that pumped or cleaned the grease interceptor, and the amount of waste that was removed. Such records shall be made available to the Director upon request. The removed contents from any grease interceptor shall be handled by a person licensed to haul such waste and shall be disposed of in accordance with Federal, State and local regulations. (7) Required maintenance. (a) Grease interceptors shall be maintained by regularly scheduled cleaning so that they will properly operate as intended to efficiently intercept FOG and settleable materials from the facility's wastewater and prevent the discharge of said materials into the City's wastewater collection and treatment systems, or if toxic, noxious, or malodorous conditions associated with such interceptors create a public nuisance or unsafe working conditions which endanger health. GGIs shall be serviced at a minimum of once every three hundred sixty-five days, or whenever the combined thickness of FOG and settleable materials is greater than twenty-five percent of the hydraulic working capacity of any grease interceptor chamber. HMGIs with a liquid volume less than one hundred gallons shall be serviced at a minimum of once every thirty days. HMGIs with a liquid volume of one hundred one to five hundred gallons shall be serviced at a minimum of once every ninety days. HMGIs with a liquid volume more than five hundred gallons shall be serviced at a minimum of once every three hundred sixty-five days. (b) The Director may require more frequent cleaning than that prescribed in subsection (a) above. A variance from the requirement in subsection (a) may be obtained if the industrial user can demonstrate through analytical data that less frequent cleaning is sufficient. The industrial user will be required to continue to monitor, on an ongoing basis, the facts supporting the variance in order to continue to support the decrease in cleaning frequency. (c) Maintenance of grease interceptors shall be done in a workman-like manner and only by a business or professional normally engaged in the servicing of such plumbing fixtures. (d) In the event a grease interceptor is not properly maintained by the industrial user, owner, lessee, or authorized representative of the industrial user, the Director may authorize such maintenance work be performed on behalf of the industrial user. The costs of such maintenance shall be billed directly to the industrial user or property owner and shall become part of the charges due and owing to the City. (e) Biological treatment or enzyme treatment shall not be a substitute for the servicing of a grease interceptor. Use of enzymes or other chemical or biological treatment or product that emulsifies or acts to emulsify FOG is prohibited. (f) An industrial user must document each pump-out of a grease interceptor with a waste manifest or trip ticket, which must be kept by the industrial user on site for at least three years. (g) An industrial user must take reasonable steps to assure that all waste is properly disposed of in accordance with Federal, State and local regulations (i.e. through a statement certifying proper disposal by the hauler included on the waste manifest or trip ticket for each load). (C) Best management practices for sand/oil interceptors. (1) Applicability. These BMPs establish requirements for any facility that has the potential to discharge petroleum oil, mineral oil, cutting oils, non-food grease and solids. All facilities subject to these BMPs must comply with the requirements which include the requirement for installation and proper operation and maintenance of an interceptor, as well as reporting requirements. (2) For purposes of this subsection (C) and parallel references within this Chapter, "sand/oil interceptor" or "interceptor" means a plumbing appurtenance or appliance that is installed in a sanitary drainage system to intercept sand (or other aggregate) and petroleum-based oil and grease from a wastewater discharge; is designed with consideration of retention times, volumes in gallons calculated for each facility, and gravity separation; and includes one or more baffles and a minimum of two compartments. (3) A sand/oil interceptor that was legally and properly installed at an industrial user's facility prior to the effective date of this Chapter and that does not conform to the requirements of this Chapter shall be acceptable as an alternative if such device is effective in removing floatable and settleable material and is designed and installed is such a manner that it can be inspected and properly maintained. If the Director determines at any time that such interceptor is incapable of adequately retaining the floatable and settleable material or if it was installed in such a manner that it cannot be inspected and properly maintained, the industrial user shall install an interceptor that complies with all City codes within ninety days after being notified of such requirement. (4) Implementation. These interceptor requirements may be implemented by letter, order, authorization, permit or other appropriate control mechanism specified by the Director. (5) General control requirements. (a) An interceptor shall be required for the proper handling of liquid wastes which may be harmful to, or cause obstruction in, the wastewater collection system or cause or contribute to pass through or interference with respect to the wastewater treatment system. (b) It shall be the responsibility of the industrial user or the owner of the property, or both, to contact the City's building and safety function in order to obtain any necessary permits for the installation of any interceptor or any modifications to the facility's plumbing. Application requirements and the installation of interceptors, as well as any other modifications to plumbing systems, shall be in accordance with applicable building-related codes, including without limitation the edition of the Uniform Plumbing Code most recently adopted by the City, together with local City amendments to that Code. Written approval from the City must be obtained prior to installation of any interceptor. The timing of review and approval of permits shall in no way relieve the industrial user of its responsibility to produce discharges acceptable to the City under the provisions of this Chapter. (c) Toilets, urinals and similar fixtures shall not discharge through an interceptor. Such fixtures shall be plumbed directly into the wastewater collection system. (d) An industrial user shall ensure that interceptors are accessible for inspection, cleaning, and removal of sand, oils and other accumulated wastes. (e) An industrial user shall always maintain interceptors at its own expense and keep them in efficient operating condition by the regular removal of waste materials. (6) Required maintenance. (a) Each sand/oil interceptor shall be maintained by regularly scheduled cleaning so that it will properly operate as intended to efficiently intercept the sand and oil from the industrial user's wastewater and prevent the discharge of said materials into the City's wastewater collection and treatment systems. An interceptor shall be serviced at a minimum of once every three hundred sixty-five days, or more frequently as deemed necessary or appropriate by the Director. The industrial user should periodically check the interceptor for the accumulation of pollutants or solids to avoid exceeding the capacity of the interceptor. The Director may require more frequent servicing or cleaning. A variance from this requirement may be obtained when the industrial user can demonstrate with analytical data that less frequent cleaning is sufficient. (b) Maintenance of interceptors shall be performed in a professional and competent manner, and in accordance with applicable professional standards. Such work shall be performed only by businesses or professionals qualified to engage, and regularly engaged, in the servicing of such plumbing fixtures. (c) In the event an interceptor is not properly maintained by the industrial user, or by an owner or lessee, the Director may authorize such maintenance work be performed on behalf of the facility. The costs of such maintenance shall be billed directly to the customer and shall become part of the charges due and owed to the City. (d) An industrial user must document each pump-out of an interceptor with a waste manifest or trip ticket, which must be kept by the industrial user on site for at least three years. (e) An industrial user must take reasonable steps to assure that all waste is properly disposed of in accordance with Federal, State and local regulations (i.e. through a statement certifying proper disposal by the hauler included on the waste manifest or trip ticket for each load). (f) Each industrial user that is required to use and maintain an interceptor shall keep a record of every time the interceptor is pumped or cleaned or repaired. This record shall include the date, the name of the company that pumped or cleaned the interceptor and the amount of waste that was removed. Such records shall be made available to the Director upon request. The removed contents from any interceptor shall be handled by a person licensed to haul such waste and shall be disposed of in accordance with Federal, State and local regulations. (D) Best management practices for dental wastewater dischargers. (1) Applicability. These BMPs apply to dental wastewater dischargers. A dental wastewater discharger is not considered an SIU unless expressly so designated by the Director. Dental wastewater dischargers are not considered a CIU. These BMPs do not apply to dental wastewater dischargers that: (a) Exclusively practice one or more of the following dental specialties: Oral pathology, oral and maxillofacial radiology, oral and maxillofacial surgery, orthodontics, periodontics, or prosthodontics; (b) Discharge wastewater from a mobile unit operated by another dental wastewater discharger; (c) Do not discharge any amalgam process wastewater to a POTW, such as dental wastewater dischargers that collect all dental amalgam process wastewater for transfer to a Centralized Waste Treatment facility as defined in 40 CFR Part 437; or (d) Do not place dental amalgam, and do not remove amalgam except in limited emergency or unplanned, unanticipated circumstances, and that certify such to the City as required in 40 CFR 441.50. (2) Definitions.

(E) Best management practices for the acceptance of trucked and hauled waste. (1) Applicability. The requirements established in this subsection (E) shall apply to persons and operators of companies who discharge trucked and hauled waste to the POTW, including any discharge that enters the City's wastewater treatment system. Where the Director elects to allow hauled waste to be accepted by the POTW, the following shall apply: (a) Hauled wastes may be introduced into the POTW only at locations designated by the Director, and at such times as are established by the Director. (b) The Director shall have the right to refuse any hauled waste load. (c) Waste haulers are prohibited from discharging wastes that would violate the standards regarding prohibited discharges that are specified in Section 14.17.015. (d) Waste haulers are prohibited from discharging hazardous wastes to the POTW or other wastes that are generated by a CIU. (e) Waste haulers shall comply with specific pollutant limitations established by the City specific to the hauled waste to be discharged. (f) The Director shall require compliance with these BMPs by permit, authorization to discharge, letter, or another control mechanism. The Director may require generators of the hauled wastes to obtain a control mechanism. (g) The Director may sample and analyze the hauled wastes or require the hauler to perform such sampling and analysis to verify that each hauled load complies with applicable pretreatment standards or requirements, or both. (h) The Director may sample and analyze the hauled wastes or require the hauler to perform such sampling and analysis at the location where the waste is generated. (i) The Director may require an industrial waste hauler to receive prior approval or consent before discharging. (j) A waste hauler must notify the Director of any new commercial or industrial customers or changes in the nature of hauled waste originating from existing customers. Customer lists shall be considered confidential business information under Federal law and regulations if designated as such by the waste hauler. (k) The Director may restrict the maximum number of loads that a waste hauler may discharge during a specific period of time, and the discharge rate of each load. (l) Waste haulers must provide a manifest form or similar trip ticket for every load prior to discharge. The form or ticket shall include, at a minimum: (i) The name and address of each customer or source of waste; (ii) The number of any permit(s) required by any jurisdiction in order to haul or dispose of waste; (iii) Truck identification; (iv) Volume of wastewater from each source; (v) Type of waste to be discharged; (vi) Known or suspected pollutants present in load(s); (vii) Signatory certification; and (viii) Certification that the hauled waste is not hazardous. (m) Waste haulers shall use a manifest form/trip ticket approved by the Director. (n) The Director may impose fees or charges for hauled wastes. (o) The waste hauler shall: (i) Maintain tanks, pumps, valves, hoses, racks, cylinders, diaphragms, pipes, connections, and other appurtenances on a vehicle in good repair and free from leaks. (ii) Provide a safety plug or cap for each tank. (iii) Ensure that the vehicle exterior is clean at the beginning of each workday prior to entry to the POTW. (iv) Clean the inside of tanks to ensure that non-permitted residual wastes are not left in the tank and allowed to mix with permitted wastes. (v) Ensure that tanks are an integral part of a vehicle to transport liquid waste. Portable tanks or other containers temporarily installed in vehicles are prohibited (unless prior approval is obtained from the Director, e.g. portable toilets). (vi) Ensure that piping, valves, and connectors (excluding the discharge hose) are permanently attached to the tank or vehicle, or both. (vii) Ensure that tanks are liquid tight and are constructed so that every interior and exterior portion can be easily cleaned. (viii) Ensure that the openings of tanks are constructed so that collected waste will not spill during filling, transfer, transport or disposal. (ix) Provide for outlet connections that are constructed so that no liquid waste will leak, run, or spill out from the vehicle. (x) Provide for outlets that are of a design and type suitable for the liquid waste handled and capable of controlling flow or discharge without spillage and undue spray on or flooding of immediate surroundings while in use. (xi) Ensure that pumps, valves, cylinders, diaphragms, and other appurtenances are of a design and type suitable for the type of waste handled, capable of operation without spillage, spray, or leakage, and capable of being easily disassembled for cleaning. (2) Authorized disposal site. Waste haulers may dispose of waste only at a location that is properly permitted to receive such waste. In the case of waste to be disposed of at a location that has the potential to enter the POTW, disposal of such waste at that location must first be authorized in writing by the Director before the location may receive trucked or hauled waste. (3) Sanitation and safety standards. Each hauler who discharges wastes to the POTW shall be responsible for cleanliness and safety practices at the points of disposal, including the prompt cleanup of any spills. Each hauler is also responsible for keeping vehicles used and related facilities clean and in good repair while being used for disposal to the POTW. These sanitary and safety practices shall be carried out in a manner acceptable to the Director. Failure to comply with these sanitation and safety standards shall be grounds for suspension of a permit, authorization to discharge, or other control mechanism. (4) Quality of wastes. Wastes approved for discharge to the POTW shall be representative of what the waste hauler disclosed in the manifest. The waste hauler consents to the Director's right to sample and analyze the contents of any vehicle utilizing the POTW for the discharge of wastes and charge the industrial user for such sampling and analytical costs. The purpose of such sampling and analysis will be to determine conformance with this Chapter. It shall be the responsibility of any industrial user whose discharge is at issue to assist in sample collection as required by the Director. (5) Performance bond. Waste haulers subject to regulation under this subsection (E) may be required to secure and maintain a bond in an amount as specified by the City, indemnifying the City against damages sustained by reason of any spill or any dumping or discharge of any liquid waste, hazardous waste, or incompatible waste within the jurisdictional limits of the City. Proof of bonding shall be provided to the City prior to authorization to discharge. In addition, the City may decline to authorize discharge to any industrial user who has failed to comply with any provision of this Chapter unless such industrial user first files a satisfactory bond, payable to the City, in a sum not to exceed a value determined by the City to be necessary to achieve consistent compliance. (6) Suspension of discharge. The City, at its discretion, may revoke an authorization to discharge and take other enforcement actions as specified in Section 14.17.075. Violations that may result in a suspension of authorization to discharge include: (a) Failure to submit accurate or timely reports; (b) Failure to pay charges or fees when due; (c) Failure to maintain vehicles as required; (d) Discharging waste at a location other than an authorized disposal site; (e) Failure to comply with applicable sanitation standards; (f) Discharging of industrial sludges or other unacceptable wastes into the POTW; (g) Failure to maintain valid and current registrations, permits, and licenses as required by any local, State or Federal regulation or requirement; or (h) Other violations of this Chapter when it is determined that suspension is necessary to protect the POTW.

(Ord. No. 6891, § 2, 11-6-24)
