Event description

Description

Who should attend this workshop

Stormwater program staff, municipal staff, and any other Bay Area MRP Permittees or individuals that are involved in planning and/or implementing urban stormwater control measures designed to reduce urban runoff discharges of PCBs and other pollutants.

Workshop Highlights

Guidance for locating and referring properties that are sources of PCBs.

Results of the enhanced municipal O&M pilot studies.

Challenges and lessons learned relative to using green infrastructure and other structural controls to treat PCBs and other pollutants in stormwater.

Discussions of costs and potential pollutant load reductions.

Guidance that will inform selecting among various types of pollutant controls or combinations of controls to apply in various types of watersheds or other management areas.

Background

CW4CB was funded by a grant from the U.S. EPA to BASMAA and matching funds from Bay Area countywide municipal stormwater management programs. The project partners included several Bay Area cities (Cities of Oakland, Richmond, San Carlos, San Jose, and Vallejo).

CW4CB had four key tasks, the first three of which were field studies in selected watersheds surrounding the Bay, with a focus on old industrial areas with elevated PCBs levels. The studies aimed to evaluate on a pilot-scale a variety of potential methods to reduce the amount of PCBs and mercury conveyed to the Bay by urban runoff. The fourth task was an outreach program to targeted communities. In summary, the four tasks were:

  1. Identified properties that are sources of PCBs or mercury and referred to regulatory agencies for abatement.
  2. Evaluated enhancement of municipal O&M activities such as street sweeping that remove sediments and associated pollutants, including PCBs and mercury.
  3. Evaluated structures (e.g., green infrastructure) to filter or otherwise treat urban runoff to remove pollutants, including PCBs and mercury.
  4. Partnered with community based organizations to conduct targeted outreach to consumers of Bay fish about the health risks due to pollutants in the fish.
