View Rule

The U.S. Environmental Protection Agency (EPA) proposed water quality criteria for selenium in the San Francisco Bay and Delta of California (Bay and Delta) on July 15, 2016. If finalized, these regulations would protect the Bay and Delta aquatic life and aquatic-dependent wildlife, including species listed as threatened and endangered under the federal Endangered Species Act, from the harmful effects of exposure to toxic levels of selenium. In the event that EPA approves selenium criteria for the Bay and Delta submitted by California prior to promulgation of a final federal rule, EPA would no longer be obligated to finalize criteria for such waters.
