Tentative Orders

A Tentative Order for cleanup and abatement is being considered for discharges of tetrachloroethene (PCE) at 2700 Willow Pass Road, Concord, Contra Costa County. The Tentative Order would require the dischargers to complete the investigation and remediation of the site. If no significant comments are received, we plan to administratively issue the Order. The public comment period is closed. The consideration of a proposed Initial Study/Subsequent Negative Declaration and a proposed Conditional Waiver of Waste Discharge Requirements for Grazing Operations in the North San Francisco Bay Region (Napa River, Sonoma Creek, Petaluma River, and Tomales Bay watersheds, and all grazing operations in Point Reyes National Seashore) has been postponed to the Regional Water Board hearing on July 9, 2025, in accordance with this revised public notice. The public comment period is closed. A NPDES Permit is being considered for the City of San Jose and City of Santa Clara, San Jose/Santa Clara Water Pollution Control Plant, San Jose, Santa Clara County. The permit would regulate discharge of secondary treated wastewater to Artesian Slough, a tributary to South San Francisco Bay via Coyote Creek. The San Francisco Bay Water Board will consider this item at its August 13, 2025, meeting. Written comments or objections to this action must be submitted no later than July 7, 2025 by 5:00 p.m. A draft NPDES permit is being considered for the Fairfield Suisun Wastewater Treatment Plant. The draft permit would regulate an average daily discharge of up to about 24 million gallons per day of treated wastewater to Boynton through a shallow water outfall and intermittently to two managed duck ponds and Ledgewood Creek. The San Francisco Bay Water Board will consider this item at its August 13, 2025, meeting. Written comments or objections to this action must be submitted no later than July 16, 2025, by 5:00 p.m.
