Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Section
71-5 of this chapter within the time limitations specified by EPA, the state, or the Director of Wastewater or his/her designee, 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 or his/her designee for review and shall be acceptable to the Director of Wastewater or his/her designee 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 Biddeford, Maine, under the provisions of this chapter.
The Director of Wastewater or his/her designee, shall evaluate
whether each SIU needs an accidental discharge/slug discharge control
plan or other action to control slug discharges. The Director of Wastewater
or his/her designee, 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 Director of Wastewater
or his/her designee, 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 batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the Director of Wastewater or his/her designee of any accidental or slug discharge, as required by Section
71-35 of this chapter; 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.
