Users shall provide wastewater treatment as necessary to comply with this part and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in Article
XI of this part within the time limitations specified by EPA, the state, or the Borough, 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 Pretreatment Coordinator for review, and shall be acceptable to the Pretreatment Coordinator 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 Pretreatment Coordinator under the provisions of this part.
The Pretreatment Coordinator shall evaluate whether each SIU
needs an accidental discharge/slug discharge control plan or other
action to control slug discharges. The Pretreatment Coordinator 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 Pretreatment Coordinator may develop
such a plan for any user. An accidental discharge/slug discharge 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 Chief Operator of the POTW treatment plant of any accidental or slug discharge, as required by §
192-105 of this part; and
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.
Discharge of filter backwash water to the POTW shall be regulated
as follows:
A. Granular media filter backwash water may be discharged to the POTW,
subject to all of the applicable provisions of this part.
B. Diatomaceous earth filter backwash, if discharged to the POTW, shall
be connected to the POTW through settling tanks with no less than
three months storage capacity of spent diatomaceous earth, which tanks
shall be accessible for removing solid waste for disposal.
The use of mechanical garbage grinders producing a finely divided
mass, properly flushed with an ample amount of water, shall be permitted,
upon the condition that no such mechanical garbage grinder used for
commercial or business purposes shall be installed until permission
for such use has been obtained from the Pretreatment Coordinator.
