Contra Costa County Environmental Protection

The regulations developed and enforced by the Contra Costa County EPA Office are based on environmental laws adopted by the U.S. Congress and signed by the President. Regulations provide the detailed technical and operational information for compliance with environmental laws. The procedure for creating a regulation involves publishing the proposed regulation in the Federal Register and providing an opportunity for the public and stakeholders to submit comments. When finalizing the regulation, the EPA considers any comments received from the Contra Costa County public and other stakeholders during the public comment period. Once finalized, the regulation is codified in the Code of Federal Regulations. The EPA has developed regulations for major environmental legislation including the Clean Air Act, the Clean Water Act, the Toxic Substances Control Act, and the Resource Conservation and Recovery Act.

EPA Inspections & Violations

After a regulation is codified, the Contra Costa County EPA Office monitors compliance through on-site monitoring, inspections, reporting requirements, and investigations. When an instance of non-compliance is identified, the EPA has multiple options for enforcement action depending on the type and severity of the violation. The EPA may pursue civil administrative actions or civil lawsuits in Contra Costa County Courts, and in some cases, the EPA may negotiate with a violator to voluntarily take corrective action regarding a violation. The EPA can also seek the criminal prosecution of a violator.

Contra Costa County EPA Grants

The EPA awards approximately $4 billion annually nationwide in grants, including grants for Contra Costa County non-profit organizations, Contra Costa County and local governments, California State, and educational institutions.
