(A) Pretreatment Facilities. Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in § 30.500(A) within the time limitations specified by EPA, the state, or the Superintendent, 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 Superintendent for review, and shall be acceptable to the Superintendent before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from The City of Morgantown Utilities Commission responsibility of modifying such facilities as necessary to produce a discharge acceptable to The City of Morgantown Utilities Commission under the provisions of this article.
(B) Additional Pretreatment Measures.
(1) Whenever deemed necessary, the Superintendent may require 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 wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this article.
(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. An individual wastewater discharge 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, and cleaned by the user at their expense.
(4) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(5) In the maintenance of grease, oil and sand interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates, quantity and the means of disposal. The city may require reporting of such information for their review. Any removal and hauling of the collected materials not performed by the owner(s) personnel must be performed by currently licensed waste disposal firms. Interceptors shall also comply with applicable regulations of the Butler County Health Department.
(C) Accidental Discharge/Slug Discharge Control Plans. The Superintendent shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Superintendent may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the Superintendent may develop such a plan for any user. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
(1) Description of discharge practices, including nonroutine hatch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the Superintendent of any accidental or slug discharge, as required by § 30.304(F); and
(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 operations, control of plant site runoff, 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) 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 waste shall not violate § 30.500 or any other requirements established by the City of Morgantown Utilities Commission. The Superintendent may require septic tank waste haulers to obtain individual wastewater discharge.
(2) The Superintendent may require haulers of industrial waste to obtain individual wastewater discharge permits. The Superintendent may require generators of hauled industrial waste to obtain individual wastewater discharge. 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 article.
(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 industrial waste hauler, permit number, truck identification, names and addresses of sources of waste, and. volume and characteristics of waste. The form shall identify the type of industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
