Chapter 43: Industrial Wastewater

Overview (1)

This chapter outlines SLAC programs and responsibilities required to comply with the rules and regulations regarding industrial wastewater and sanitary sewers administered by the South Bayside System Authority (SBSA) and the West Bay Sanitary District (WBSD). The relationship between SLAC and the SBSA and the WBSD is formalized in discharge regulations and wastewater discharge limits set forth in a permit. These limits are necessary to protect the sanitary sewer system and treatment plant as well as its operators, and are based on the ability of the sewage treatment plant to treat wastewater to safe levels before discharge to the San Francisco Bay.

Hazards/Impacts (1.1)

Pouring hazardous material down sinks or floor drains could cause permit limits to be exceeded. Hazards associated with discharging industrial wastewater into the sewer system in excess of permit limits include damaging the water treatment plant and polluting water resources.

Factors that may impact SLAC include increased restrictions and conditions on quality and quantity of discharges to the sanitary sewer. The SLAC industrial wastewater program addresses these through current compliance and the establishment of a management system that can adapt to a more restrictive regulatory environment in the future.

Scope (2)

The requirements of this chapter apply to all personnel, including SLAC employees, subcontractors, users, and visitors.

This chapter describes the SLAC industrial wastewater program requirements and conditions as specified in the Mandatory Wastewater Discharge Permit issued by the SBSA.

This chapter also includes applicable best management practices (BMPs) that help keep SLAC wastewater within permit limits.

This chapter pertains only to wastewater discharged to the sanitary sewer. For regulations and requirements regarding water that enters the storm drain system, see Chapter 26, "Stormwater".

The wastewater discharge permit accidental release plan requirement is met by the Consolidated Chemical Contingency Plan (CCCP) [pdf]. The CCCP fulfills numerous emergency planning requirements, including those for a hazardous materials business plan (HMBP), which can be used in lieu of a separate accidental release plan.

Implementation (8)

The requirements of this chapter will be implemented according to the schedule in Industrial Wastewater: Implementation Plan [pdf].
