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.
(a)
Whenever deemed necessary, the Director of Wastewater or his/her
designee 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 chapter.
(b)
The Director of Wastewater or his/her designee may require any person
discharging into the POTW to install and maintain on his/her property
and at his/her 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.
(c)
Grease, oil, and sand interceptors shall be provided when, in the
opinion of the Director of Wastewater or his/her designee, 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 of Wastewater
or his/her designee, shall be so located to be easily accessible for
cleaning and inspection. Such interceptors shall be inspected, cleaned,
and repaired by the user at his/her expense.
(d)
Users with the potential to discharge flammable substances may be
required to install and maintain an approved combustible gas detection
meter.
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.
(a)
Septic tank waste may be introduced into the POTW only at locations designated by the Director of Wastewater or his/her designee and at such times as are established by the Director of Wastewater or his/her designee. Such waste shall not violate Article II of this chapter or any other requirements established by the City of Biddeford, Maine. The Director of Wastewater or his/her designee may require septic tank waste haulers to obtain individual wastewater discharge permits.
(b)
The Director of Wastewater or his/her designee may require haulers
of industrial waste to obtain individual wastewater discharge permits.
The Director of Wastewater or his/her designee may require generators
of hauled industrial waste to obtain individual wastewater discharge
permits. The Director of Wastewater or his/her designee also may prohibit
the disposal of hauled industrial waste. The discharge of hauled industrial
waste is subject to all other requirements of this chapter.
(c)
Industrial waste haulers may discharge loads only at locations designated
by the Director of Wastewater or his/her designee. No load may be
discharged without prior consent of the Director of Wastewater or
his/her designee. The Director of Wastewater or his/her designee shall
have each load sampled and analyzed for all local limits before discharge
to ensure compliance with applicable standards.
(d)
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.
