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 §
435-5 of this chapter within the time limitations specified by the EPA, the state, or the POTW, 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 Superintendent, or his/her designee, for review, and shall be acceptable to the Superintendent, 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 under the provisions of this chapter.
At least once every two years, the POTW shall evaluate whether
industrial/commercial users need an accidental discharge/slug control
plan. The Superintendent, or his/her designee, may require any user
to develop, submit for approval, and implement such a plan. Note:
All significant industrial users (SIUs) are required to prepare and
implement a slug control plan as documented in their wastewater discharge
permits [40 CFR 403.8(f)(1)(iii)(B)(6)]. New SIUs will be required
to prepare the plan within one year of the issuance of their wastewater
discharge permit [40 CFR 403.8(f)(2)(vi)]. An accidental discharge/slug
control plan shall address, at a minimum, the following:
A. General information: name and address, facility contact, description
of discharge practices, including non-routine batch discharges, security
provisions and employee training;
B. Facility layout flow diagrams: general layout, including mapping
of manufacturing, storage, transportation, disposal areas, location
of all floor drains, wash sinks, etc.;
C. Material inventory: description of stored chemicals, types, volumes,
containers, etc.;
D. Slug reporting: procedures for immediately notifying the Superintendent, or his/her designee, of any accidental or slug discharge, as required by §
435-35 of this chapter;
E. Spill and leak prevention equipment, operations and maintenance procedures:
definition of available equipment, plans to obtain needed equipment
and 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, and measures
for containing toxic organic pollutants, including solvents;
F. Emergency response equipment and procedures: inventory and location
of equipment and procedures;
G. Training program: assurance that the plan is implemented by providing
for employee training; and
H. Certification: a certification by a professional (person with knowledge
of plan and its purpose) that the plan is adequate to prevent and
control slug and accidental discharges.
