  • CalEPA Regulated Site Portal
    The CalEPA Regulated Site Portal is a website that combines data about environmentally regulated sites and facilities in California into a single, searchable database and interactive map. The portal was created to provide a more holistic view of regulated activities statewide. By combining data from a variety of state and federal databases, the portal provides an overview of regulated activities across the spectrum of environmental programs for any given location in California. These activities include hazardous materials and waste, state and federal cleanups, impacted ground and surface waters, and toxic materials. The portal combines information from the following databases:
  • Cal/OSHA – Inspection and enforcement information reported to federal OSHA
  • CERS – The California Environmental Reporting System
  • CIWQS – The California Integrated Water Quality System
  • EIS – U.S. EPA’s Air Emission Inventory System
  • EnviroStor – Permitting, enforcement and cleanup activities at hazardous waste facilities and sites with known or suspected contamination
  • GeoTracker – Impacted groundwater sites within the state, such as leaking underground storage tanks, cleanup sites, and permitted facilities such as landfills and operating underground storage tank facilities
  • SMARTS – The Stormwater Multiple Application and Report Tracking System
  • SWIS – The Solid Waste Information System
  • TRI – The Toxics Release Inventory
