Columbia Accidental discharges/slug control plans ordinance (§ 22-222)

(a) At least once every permit cycle, the director shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The director may require any user to develop, submit for approval, and implement such a plan. Alternatively, the director may develop such a plan for any user. 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 any accidental or slug discharge, as required by section 22-222.1 of this article, including any discharge that would violate a prohibition under section 22-215 of this article, with procedures for follow-up written notification within five (5) days; and

(4) Procedures to prevent adverse impact from any accidental spills. 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 measures and equipment for emergency response.

(b) Significant industrial users shall notify the POTW immediately of any changes at its facility affecting the potential for a slug discharge.
