13.06.180 Accidental Discharge/Slug Control Requirements.
The Manager may require any user to develop and implement an accidental discharge/slug control plan, also known as an Accidental Spill Prevention Plan (ASPP). Where deemed necessary by the County, facilities to prevent accidental discharges or slug discharges of pollutants shall 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 shall be submitted to the County for review and approval. The County shall determine which user is required to develop a plan and require said plan to be submitted within a scheduled time frame after notification by the County. Each user shall implement its ASPP as approved by the County. Review and approval of such plans and operating procedures by the County shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW or the environment, fish kills, or any other damage to person or property; nor shall such review and approval relieve the user of any fines, civil penalties, or other liability which may be imposed by this Chapter or other applicable law.
A. Any user required to develop and implement an accidental discharge/slug control plan shall submit a plan which addresses, at a minimum, the following:
1. Description of discharge practices, including non-routine batch discharges;
2. Description of stored chemicals;
3. Description of all potential discharge pathways to the POTW;
4. 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 standards in PCC 13.06.050 through 13.06.090; and
5. 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 hazardous or toxic pollutants (including solvents), and/or measures and equipment for emergency response.
B. Users shall notify the County Wastewater Treatment Plant Operations Manager immediately upon the occurrence of a "slug" or "accidental discharge" of substances regulated by this Chapter. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Any user who discharges a slug load shall be liable for any expense, loss, or damage to the POTW, in addition to the amount of any fines imposed on the County under State or federal law.
C. Within five days following an accidental discharge, the user shall submit to the Manager 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 shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW or the environment, fish kills, or any other damage to person or property; nor shall 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. The County may require signs to 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, and may require that employers instruct all their employees who may cause or discover such a discharge with respect to emergency notification procedures.
