Users shall provide wastewater treatment as necessary to comply with this Part 2 and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in § 570-24 of this Part 2 within the time limitations specified by EPA, the state or the Director of Wastewater, 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 of Wastewater for review and shall be acceptable to the Director of Wastewater 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 Director of Wastewater as operator under the provisions of this Part 2.
A. 
Whenever deemed necessary, the Director of Wastewater 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 such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this Part 2.
B. 
The Director of Wastewater 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. A wastewater discharge permit may be issued solely for flow equalization.
C. 
Grease, oil and sand separators shall be provided when, in the opinion of the Director of Wastewater, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except that such separators shall not be required for residential users. Effective January 1, 1997, all restaurants and other applicable commercial establishments that may generate grease, oil, sand or other material that may cause obstructions in the sanitary sewers are required to install grease, oil and water separators of an adequate size to safeguard the sanitary sewer system. All separator units shall be of type and capacity approved by the Director of Wastewater and shall be so located to be easily accessible for cleaning and inspection. Such separators shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense.
D. 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
E. 
An adequate sampling vault or manhole must be provided in an accessible place for municipal treatment plant personnel to obtain samples and flow measurement data. The complexity of the vault will vary with the sampling requirements the Director determines necessary to protect the treatment plant and receiving stream. Should the Director desire continual flow recording and long duration, twenty-four-hour composite sampling, then a more complex manhole would be mandatory complete with 100 volt AC. Samples collected could be divided between the industrial user and Director for analysis if so desired by the industry. The sampling vault should be located so as to give access to City personnel at any time. Such sampling manholes shall be installed and maintained at the user's expense.
A. 
At least once every two years, the Director of Wastewater shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Director of Wastewater may require any user to develop, submit for approval and implement such a plan. Alternatively, the Director of Wastewater may develop such a plan for any user.
B. 
Throughout the industrial facility, adequate secondary containment or curbing must be provided to protect all floor drains from accidental spills and discharges to the receiving sewers. Such curbing should be sufficient to hold 150% of the total process area tank volume. All floor drains found within the containment area must be plugged and sealed. Spill trough and sumps within process areas must discharge to appropriate pretreatment tanks. Secondary containment should be provided for storage tanks which may be serviced by commercial haulers and for chemical storage areas. An accidental discharge/slug control plan shall address, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the Director of Wastewater of any accidental or slug discharge, as required by § 570-53 of this Part 2; 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.
Septic tank waste from domestic sources may be introduced into the POTW only at locations designated by the Director of Wastewater and at such times as are established by the Director of Wastewater. Such waste shall not violate Article III of this Part 2 or any other requirements established by the City of Monroe as operator. The Director of Wastewater may require septic tank waste haulers to comply with the bill of lading program and identify each party contributing to the load; further, the driver must sign a certification statement. Septic tank waste will only be accepted if it was collected from a site within the boundaries of Monroe County. Septic waste must not contain any industrial or hazardous wastes.
