The superintendent may require any user to develop and implement an accidental spill prevention plan (ASPP) or slug control plan. Where deemed necessary by the city, facilities to prevent accidental discharge or slug discharges of pollutants must be provided and maintained at the user's cost and expense. An accidental spill prevention plan/slug control plan showing facilities and operating procedures to provide this protection must be submitted to the city for review and approval before implementation. The city will determine which user is required to develop a plan and require the plan be submitted within ninety (90) days after notification by the city. Each user must implement its ASPP/slug control plan as submitted or as modified after such plan has been reviewed and approved by the city. Review and approval of such plans and operating procedures by the city does not relieve the user from the responsibility to modify its facility as necessary to meet the requirements of this section.
A. Any user required to develop and implement an accidental spill prevention plan (ASPP)/slug control plan must submit a plan which addresses, at a minimum, the following:
1. Description of discharge practices, including nonroutine batch discharges; and
2. Description of stored chemicals; and
3. Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharge standards in section 13.20.2.1 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.
B. Users must notify the city wastewater treatment plant immediately upon the occurrence of a "slug" or "accidental discharge" of substances prohibited by this chapter. The notification must include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Any affected user will be liable for any expense, loss, or damage to the POTW, in addition to the amount of any fines imposed on the city on account thereof under state or federal law.
C. Within five (5) days following an accidental discharge/slug discharge, the user must submit to the 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. Such notification does not relieve the 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 will such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this chapter or other applicable law.
D. Within thirty (30) days of a slug discharge, the user must resample its discharge and demonstrate that the user is in compliance with its discharge limitations.
E. Signs must be permanently posted in conspicuous places on the user's premises advising employees whom to call in the event of a slug or accidental discharge. Employers must instruct all employees who may cause or discover such a discharge with respect to emergency notification procedures. (Ord. 3374 §2, 2010)
