Enforcement Data

CalEPA publishes annual enforcement reports with summary enforcement data.

CalEPA Regulated Site Portal
This website combines information about environmentally regulated facilities and sites statewide from multiple state and federal data sources into a single searchable database and interactive map. Information on the CalEPA Regulated Site Portal comes from five sources: California Environmental Reporting System, EnviroStor, GeoTracker, the California Integrated Water Quality System (CIWQS) and the Toxics Release Inventory (TRI).

The Air Resources Board (ARB) maintains databases and produces reports relevant to air quality and emissions, as well as provides online registration and reporting services for its programs.

The Department of Pesticide Regulation (DPR) maintains a database of administrative actions taken by county agricultural commissioners dealing with pesticide registration and permit violations.

Enforcement Action Tracking System

Hazardous Waste
Department of Toxic Substances Control (DTSC) maintains a database of detailed information on inspections and enforcement actions of hazardous waste facilities, including information on permits, corrective actions, and cleanup projects. The Unified Program publishes enforcement summaries and “CUPA-to-State” summary reports received from CUPAs.

State law requires any person suing “in the public interest” to enforce Proposition 65, “The Safe Drinking Water and Toxic Enforcement Act of 1986”, to notify the Attorney General of the violation 60 days in advance of filing a lawsuit, called a “60-day notice.” The AG maintains a database of 60-day notices on its Proposition 65 website.
