NPDES Permit Reissuance Technical Support

East Bay Dischargers Authority (EBDA)

EBDA has a 119 mgd permitted discharge capacity to Lower San Francisco Bay. EOA has assisted EBDA, beginning with their 2000 permit reissuance, and has helped EBDA manage and negotiate each 5-year NPDES permit application process since 2012. EOA coordinated development of the permit application packages for EBDA that included data and information on the EBDA common outfall and from its four member agencies (City of Hayward, City of San Leandro, Oro Loma Sanitary District and Union Sanitary District). Specific tasks EOA conducted included: Developed permitting strategy; prepared draft and final application packages for all six agencies (EBDRA, City of Livermore, and Dublin San Ramon Sanitation District); provided data evaluation and supporting documentation for monitoring reduction requests; compiled, validated, and summarized eight years of monitoring data for seven agencies to support Pretreatment Program monitoring reduction request; compiled EBDA combined outfall data and prepared Reasonable Potential Analysis; calculated resultant effluent limits; negotiated permit requirements; and reviewed and prepared comments on Tentative Orders.
