In one of the final acts of the Biden Administration on January 10, 2025, the U.S. Environmental Protection Agency (EPA) sent a letter to the State Water Resources Control Board regarding two petitions filed with the EPA by the Delta Tribal Environmental Coalition (DTEC) in December 2022 DTEC includes the Buena Vista Rancheria of Me-Wuk Indians, Shingle Springs Band of Miwok Indians, Winnemem Wintu Tribe, Little Manila Rising and Restore the Delta. The letter urged swift action on the San Francisco Bay-Delta Plan in support of Tribal and Bay-Delta communities at a time when the Bay-Delta ecosystem is in its worst-ever crisis as Central Valley salmon and Delta fish populations collapse.
