15.20.075 Slug Control Plan.
A. General Provisions. All users shall provide protection from accidental or intentional discharges of materials that may interfere with or cause pass through to the sewage system by developing and implementing a slug control plan. Facilities necessary to prevent the discharge of prohibited or restricted substances shall be provided and maintained at the user’s cost and expense. A plan showing facilities and operating procedures to provide this protection shall be submitted to the City for review and approval before implementation of the plan. Review and approval of the 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 BC Chapters 15.20 through 15.80. The plan shall be posted and available for inspection at the facility during normal business hours. SIUs must notify the City immediately of any changes at their facilities, not already addressed in their slug control plan or other slug control requirements, that may affect the potential for a slug discharge.
B. Specific Provisions. The City may require any user to develop, submit for approval, and implement a slug control plan. The need and requirement for a plan shall be included in the user’s wastewater discharge permit.
C. A 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 City of any accidental or slug discharge; and
4. Procedures to prevent adverse impact from any accidental or slug discharge. 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.
D. Users shall notify the City immediately after the occurrence of a slug or accidental discharge of substances regulated by BC Chapters 15.20 through 15.80. The notification shall include location, date and time of discharge, type of waste, concentration and volume, and corrective actions. Any affected user shall be liable for any expense, loss, or damage incurred by the City, in addition to the amount of any penalties imposed on the City as a result of the discharge.
E. Within five days following an accidental discharge, the user shall submit to the City a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. The notification does not relieve the user of any expense, loss, damage, or other liability that may be incurred as a result of damage to the sewage system, fish kills, or any other damage to person or property. The notification does not relieve the user of any fines, civil penalties, or other liability that may be imposed by BC Chapters 15.20 through 15.80 or other applicable law.
F. Signs shall 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 shall instruct all employees who may cause or discover such a discharge with respect to emergency notification procedures. [Ord. NS-2182, 2012]
