(A) Pretreatment facilities. Industrial users shall provide necessary wastewater treatment as required to comply with this subchapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in § 51.23 within the time limitations specified by the EPA, the state, or the Superintendent - whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the Superintendent shall be provided, operated, or maintained at the industrial user’s expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Superintendent for review, and shall be acceptable to the Superintendent 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.
(B) Additional pretreatment measures.
(1) Whenever deemed necessary, the Superintendent may require industrial users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, 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 Superintendent may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. The facility shall be equipped with a rate of discharge controller, the regulation of which shall be directed by the Superintendent. An individual wastewater discharge permit or a general permit may be issued solely for flow equalization.
(3) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner at his expense. Records showing quantities and dates of removal of both grease and oil or sand shall be maintained by the owner. These records shall be available for city, county, state and federal inspectors. Such units shall comply with the city’s Oil and Grease Management Ordinance, as such becomes enacted.
(4) Users with the potential to discharge flammable substances may be required to install, maintain and use an approved combustible gas detection meter.
(C) Accidental discharge/slug control plans. The Superintendent may require any industrial user to develop and implement an accidental discharge/slug control plan. At least once every 2 years the Superintendent shall evaluate whether each significant industrial user needs such a plan. 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.
(1) Description of discharge practices, including non-routine batch discharges.
(2) Description of stored chemicals.
(4) 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 operation, control of plant site run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
(D) Tenant responsibility. Where an owner of the 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) Hauled wastewater.
(1) Septic tank waste may be introduced into the POTW only at locations designated by the Superintendent, and at such times as are established by the Superintendent. Such wastes shall not violate §§ 51.23 through 51.29 or any other requirements established or adopted by the city. The Superintendent may require septic tank waste haulers to obtain individual wastewater discharge permits.
(2) The Superintendent may require haulers of industrial waste to obtain individual wastewater discharge permits or general permits. The Superintendent may require generators of hauled industrial waste to obtain individual wastewater discharge permits or general permits. The Superintendent also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this subchapter.
(3) Industrial waste haulers may discharge loads only at locations designated by the Superintendent. No load may be discharged without prior consent of the Superintendent. The Superintendent may collect samples of each hauled load to ensure compliance with applicable standards. The Superintendent may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
(4) Industrial waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the waste hauler, permit number, truck identification, names and addresses of the sources of the waste, and volume and characteristics of the waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
(F) 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 §§ 51.37 through 51.39.
