Hazardous Materials Division

The goal of the Hazardous Materials Division (HMD) is to protect human health and the environment. To accomplish this goal, the HMD regulates facilities that:

• Handle or store Hazardous Materials in Hazardous Material Business Plan (HMBP) reportable amounts
• Are part of the California Accidental Release Prevention Program (CalARP)
• Generate or treat Hazardous Waste in any amount
• Generate or treat Medical Waste in any amount
• Are subject to the Aboveground Petroleum Storage Act (APSA)
• Own or operate Underground Storage Tanks (UST)

By law, every business in San Diego County involved in these activities must have a valid  Permit through the California Environmental Reporting System (CERS). You can find more details on our CERS information page. 

For more information, please visit our  CERS page. HMD Forms and HMD Guidance Documents are still available from any HMD webpage from the menu on the right side of the screen.
