Stormwater work included performing facility audits and reviewing records and Stormwater Pollution Prevention Plans (SWPPPs) for both facilities to ensure compliance with the Industrial General Stormwater Permit. Farallon provided recommendations for operational BMPs, including disconnecting roof drains from the stormwater system, revisions to the SWPPPs, and stormwater sampling procedures. The technical services were provided by Farallon to assist the facilities in addressing concerns raised by a local non-profit environmental organization.
