(a) Each user shall provide protection from accidental discharge of prohibited or restricted materials or substances established by this chapter. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user's cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Director for review, and shall be approved by the Director prior to construction of the facility. Each existing user shall complete its plan and submit same to the Director within 180 days after this chapter is in effect. No user who discharges to the City POTW after the aforesaid date shall be permitted to introduce pollutants into the system until accidental discharge protection procedures have been approved by the Director. Review and approval of such plans and operating procedures by the Director shall not relieve the user from the responsibility to modify its facility as necessary to meet the requirements of this chapter.
(b) The Director shall evaluate whether each significant industrial user needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Director may require any discharger 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 may develop such a plan for any discharger. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the authority of any accidental or Slug Discharge, as required by 933.23 (c) (3); 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, employee training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
(c) Users shall verbally notify the Director immediately upon the occurrence of a "slugload" or accidental discharge of substances prohibited by this chapter with a written notification letter to follow within three working days. Both notifications shall include location of discharge, date and time thereof, type of waste, concentration and volume and corrective actions. Any user who discharges a slugload of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to the amount of any fines imposed on the Authority on account thereof under State or Federal law.
(d) Significant industrial users are required to notify the Director of any significant changes to the discharger's operations or system which might alter the nature, quality, volume or potential for slug discharges of its wastewater at least 30 days before the change.
(e) Employers shall instruct all employees who may cause or discover a slug or accidental discharge with respect to proper emergency notification procedures. This emergency notification procedure shall include the proper person to notify at the POTW.
(f) The Director shall evaluate the need for a plan, device or structure to control a potential slug discharge at least once during the term of each significant industrial user's control mechanism or within one year of being identified a significant industrial user.
