Tentative Orders
Notice is hereby given that the California Regional Water Quality Control Board, San Francisco Bay Region, (Water Board) will hold a public hearing to consider adoption of three tentative orders containing waste discharge requirements and a Clean Water Act section 401 water quality certification for Martin Marietta Marine Operations (Martin Marietta), Lind Marine Incorporated (Lind), and Suisun Associates (a joint venture of Martin Marietta and Lind) to continue sand mining over the next 10 years from several California State Lands Commission mineral extraction lease areas in Central San Francisco Bay and Suisun Bay, and from a private lease area adjacent to Middle Ground Island in Suisun Bay (Tentative Orders). The Tentative Orders will regulate hydraulic suction dredging to obtain commercial sand that is primarily used for construction activities within the greater San Francisco Bay area and the discharge of overflow (decant water) from the dredging operations.
SUBMISSION OF WRITTEN COMMENTS: All public written comments on the Tentative Orders must be received by the Regional Water Board staff contact no later than 5:00 p.m. on Thursday September 3, 2026.

A draft NPDES permit is being considered for the C&H Sugar Company Refinery and Philip F. Meads Water Treatment Plant (Joint Treatment Plant). The draft permit would continue to regulate the discharge of cooling water from the Sugar Refinery, treated sugar refining water and domestic and commercial wastewater from the Joint Treatment Plant, and stormwater to Carquinez Strait. The San Francisco Bay Water Board will consider this item at its August 12, 2026, meeting. The public comment period is closed.
A Tentative Order terminating the cleanup requirements for Order No. 95-224, as amended by Order No. R2-2004-0065 is being considered for the discharges of tetrachloroethene (TCE) at 526 School Street, Suisun City, Solano County. If no significant comments are received, we plan to administratively issue the Order. The public comment period is closed.
A draft NPDES permit is being considered for the Livermore-Amador Valley Water Management Agency (LAVWMA) Export and Storage Facilities (Facility), owned by LAVWMA and operated by the Dublin San Ramon Services District. Most of the time, the Facility discharges treated wastewater to Lower San Francisco Bay, which is covered under a separate permit. This draft permit would regulate intermittent discharges of treated wastewater to San Lorenzo Creek and Alamo Canal through shallow water outfalls during extreme wet weather, which could occur up to 1.5 times per year. The draft permit would also regulate occasional discharges to these waterbodies to ensure operability of the outfalls. The San Francisco Bay Water Board will consider this item at its August 12, 2026, meeting. The public comment period is closed.
A Tentative Order terminating the cleanup requirements for Order No. R2-2014-0021 is being considered for the discharges of tetrachloroethene (TCE) at 6400 Sierra Court, Dublin, Alameda County. If no significant comments are received, we plan to administratively issue the Order.
A revised 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.
