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 facilites that:

All businesses in the County of San Diego that conduct any of these activities on site have to obtain and maintain a valid  Permit through the California Environmental Reporting System (CERS)

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. 

IMPORTANT. Please Read: Changes in the law might affect your facility reporting. See this link for more information.
