(A) Pretreatment facilities.
(1) Industrial users shall provide necessary wastewater treatment as required to comply with all categorical pretreatment standards, local limits and the prohibitions set out in § 51.073 above within the time limitations specified by the EPA, TCEQ, or the Superintendent, whichever is more stringent, if applicable. Any facilities required to pretreat wastewater to a level acceptable to the city shall be provided, operated, and maintained at the industrial user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the city for review, and shall be acceptable to the city before construction of the facility. The review of such plans and operating procedures will in no way relieve the industrial user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the city under the provisions of this subchapter. The city shall require the industrial user to verify prior to discharge that wastes authorized to be discharged will receive suitable treatment within the provisions of laws, regulations, subchapters, rules and orders of federal, state and local government.
(2) Industrial users responsible for discharges through a building sewer carrying industrial wastes shall, at his or her own expense and as required by the city, install an accessible and safely located control manhole, install meters and other appurtenances to facilitate observation sampling and measurement of the waste, and maintain the equipment and facilities.
(B) Additional pretreatment measures.
(1) Whenever deemed necessary, the Superintendent may require industrial users to control the quantities and rates of discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, require pretreatment of unacceptable discharges, require payment to cover the cost of handling and treating wastes, and such other conditions as may be necessary to protect the POTW and determine the industrial user's compliance with the requirements of this subchapter.
(2) The city has the authority to reject and refuse discharges or proposed discharges from the industrial users. If discharges or proposed discharges to the public sewer system may deleteriously affect wastewater facilities, processes, equipment, or receiving waters, create a hazard to life or health, or create a public nuisance, the city will refuse acceptance of the waste.
(3) Grease, oil and sand interceptors shall be required when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease, oil, sand, flammable wastes or other harmful ingredients; except that such interceptors shall not be required for residential users. All interceptors shall be of type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be installed, inspected, cleaned, and repaired regularly, as needed, by the owner at his or her expense.
(C) Accidental discharge/slug control plans.
(1) The Superintendent may require any industrial user to develop and implement an accidental discharge/slug control plan. The city will evaluate the SIU, within one year of being designated an SIU, to determine whether such SIU needs a plan or other action to control slug discharges (40 CFR § 403.8(f)(2)(vi)). The city shall keep records of the activities associated with slug control evaluation, and results of such activities are required to be available to the city upon request. The city shall also keep records of all information resulting from any monitoring activities required by 40 CFR Part 403, including documentation associated with BMPs. Any industrial user required to develop and implement an accidental discharge/control slug plan shall submit a plan which addresses, at a minimum, the following:
(a) Description of discharge practices, including nonroutine batch discharges.
(b) Description of stored chemicals.
(c) Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharges in § 51.073.
(d) Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment for emergency response.
(2) The Superintendent shall regulate the flow and concentration of slug loads when they may:
(a) Impair the treatment process, or cause interference or pass through;
(b) Cause damage to collection facilities;
(c) Incur treatment costs exceeding those for normal wastewater; or
(d) Render the treated wastewater unfit for stream discharge or reuse.
(D) Tenant responsibility. Where an owner of property leases premises to any other person as a tenant under any rental or lease agreement, if either the owner or the tenant is an industrial user, either or both may be held responsible for compliance with the provisions of this subchapter.
(E) Vandalism. No person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface, tamper with or prevent access to any structure, appurtenance or equipment, or other part of the POTW. Any person found in violation of this requirement shall be subject to the sanctions set out in §§ 51.081 through 51.083.
(F) Fraud and false statements. No user may in any way falsify statements or provide fraudulent information to the city. Any user that knowingly makes any false statements, representations, or certifications in any application, record, report, plan or other communication or documentation filed, or required to be provided, performed or maintained, pursuant to this subchapter, wastewater discharge permit or order, or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method required under this subchapter shall be subject to the provisions of 40 CFR 403.12(n) and penalties stipulated in §§ 51.081 through 51.083.
