(A) Accidental discharges. Each industrial user having the ability to cause interference with the POTW treatment plant or to violate the regulatory provisions of this chapter shall provide protection against accidental discharge to the POTW of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental discharge or prohibited materials from entering the POTW shall be provided and maintained at the user’s own cost and expense. All industrial users whose wastewater includes or could include compatible or incompatible pollutants in amounts great enough to cause interference with the POTW must have detailed plans on file at the city showing facilities and operating procedures to provide this protection. Plans shall be approved by the city before construction of the facility. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify its facility as necessary to meet the requirements of this chapter.
(1) Notification. In the case of an accidental or deliberate discharge of compatible or incompatible pollutants which may cause interference at the POTW or violate regulatory requirements of this chapter, it shall be the responsibility of the industrial user to immediately telephone and notify the city of the incident. The notification shall include name of caller, location and time of discharge, type of wastewater, concentration, volume, and corrective actions.
(2) Written report. Within ten working days following such an accidental or deliberate discharge, the industrial user shall submit to the Wastewater Superintendent a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Follow-up reports may be required by the city as needed. Such report, or reports, shall not relieve the industrial user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such report relieve the user of any fines, civil penalties, or other liability which may be imposed by the chapter or otherwise. Failure to report accidental or deliberate dischargers may, in addition to any other remedies available to the city, result in the revocation of the user’s wastewater discharge permit.
(B) Slug control plan. At least once every two years, the Wastewater Superintendent shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The Wastewater Superintendent may require any user to develop, submit for approval, and implement such a plan. An accidental discharge/slug control plan shall address, at minimum, the following:
(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the Wastewater Superintendent of any accidental or slug discharge, as set forth in division (A) above and § 51.175(B) 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.
