Projects to Reduce and Control PCBs in Stormwater through TMDL Implementation

Abstract:

To address water quality impairment from nonpoint sources of PCBs, as identified in the San Francisco Bay RWQCB's PCB TMDL, this regional project would investigate options to reduce PCB loading in stormwater in anticipation of the forthcoming TMDL implementation plan and associated NPDES permit requirements.  Five major groups of projects would be implemented region-wide by municipal stormwater programs to address implementation of the PCB TMDL.  These include Pollution Prevention/Source Control BMPs; Soil/Sediment Control BMPs; Stormwater Treatment BMPs; Programmatic Activities; and Monitoring Activities.  BMPs to address and control PCB sources would be studied or implemented at pilot or larger scale by BASMAA municipalities.

Purpose: To address water quality impairment from nonpoint sources of PCBs, as identified in the PCB TMDL, this project would investigate options to reduce PCB loading in stormwater in anticipation of the forthcoming TMDL implementation plan. When finalized and approved, the PCB TMDL Implementation Plan will identify agencies, including municipalities, who will be responsible for implementing the TMDL according to requirements of the Municipal Regional Urban Runoff NPDES Stormwater Permit following TMDL adoption. As such, Bay Area municipalities propose to initiate efforts to reduce PCB loads in anticipation of TMDL adoption and NPDES municipal permit updates. This purpose of this regional project is to investigate options to reduce PCB loading through conducting feasibility and pilot studies.
