A. 
Users shall provide wastewater treatment as necessary to comply with this Part 4 and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Article VIII of this Part 4 within the time limitation specified by the EPA, the state or the Director, 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 Director for review and shall be acceptable to the Director 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 of Aberdeen under the provisions of this Part 4. Plans and specifications review and site, construction or other inspection as deemed necessary by the Director shall be performed by an engineer selected by the City. All costs for said plans and specifications review and inspections as determined by the Director shall be paid by the private owner.
B. 
Whenever deemed necessary, the Director 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 waste streams from industrial waste streams, and impose such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this Part 4.
C. 
The Director may require any person discharging into the POTW to install and maintain, on his property and at his expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
D. 
Grease, oil and sand interceptors shall be provided when, in the opinion of the Director, 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 Director 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 user at its expense.
E. 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
At least once every two years, the Director shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Director may require any user to develop, submit for approval, and implement such a plan. Alternatively, the Director may develop such a plan for any user. An accidental discharge/slug control plan shall address, 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 Director of any accidental or slug discharge, as required by § 450-75 of this Part 4.
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, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
A. 
Septic tank waste may not be introduced into the POTW.
B. 
The Director shall require generators of hauled industrial waste to obtain a wastewater discharge permit. The Director also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this Part 4.
C. 
Industrial waste haulers may discharge loads only at locations designated by the Director. No load may be discharged without prior consent of the Director. The Director may collect samples of each hauled load to ensure compliance with applicable standards. The Director may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
D. 
Industrial waste haulers must provide a water 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.
