U.S. Environmental Protection Agency Southwest, Region 9

The U.S. Environmental Protection Agency (EPA) operates within the broader Bay Area to enforce federal environmental laws, protect public health, and safeguard natural ecosystems. Based out of its regional office in San Francisco, the agency oversees environmental programs across the Pacific Southwest, with a heavy emphasis on monitoring air and water quality throughout northern California's high-traffic industrial zones. Their targeted regional presence drives critical clean-energy initiatives, regulates hazardous waste management, and leads major coastal wetland restoration projects, providing the essential regulatory framework needed to build long-term climate and community resilience.
