HMD-UST Construction and Plan Check

ATTENTION - CERS is now Available:  Starting January 1, 2013 all CUPA regulated businesses are required by law (Assembly Bill 2286) to submit business information electronically through the California Environmental Reporting System (CERS). Many of the Unified Program forms are no longer available on our website and instead must be completed online in CERS. This includes information related to Underground Storage Tanks (UST), hazardous waste tank closures, and Aboveground Petroleum Storage Act (APSA) documentation. For more information on creating a CERS account and submitting your UST documents electronically please visit our CERS Information Page.

The Department of Environmental Health (DEH) regulates the construction, operation, repair and removal of underground storage tank (UST) systems. A permit to operate a UST system in San Diego County is required by the San Diego County Code of Regulatory Ordinances Title 6, Division 8, Chapter 10. State regulations mandate additional testing and more frequent inspections at UST facilities; thus requiring close coordination between inspectors, contractors and the regulated community. 

In an effort to facilitate this coordination, the Hazardous Materials Division (HMD) established a UST Group to provide the following services throughout San Diego County:

  • Conduct all routine Inspections of all retail fuel facilities in San Diego County
  • Approve all electronic submissions regarding UST installations, repairs, upgrades and removals coming through the California Environmental Reporting System (CERS).
  • Conduct installation, repair, and upgrade inspections within San Diego County. The group consists of 5 field inspectors, a plan check senior inspector, a plan check technician, and a supervisor.

The goal of the HMD-UST Program is to protect public health, the environment and groundwater. To accomplish this goal, HMD ensures that businesses and facilities with ongoing UST operations are properly permitted and meet the monitoring requirements applicable to their type of equipment. This is accomplished during plan check and inspection activities. HMD is the lead program for permitting installations of new UST systems, UST repairs, and piping removals, including plan checks and inspections. Each UST site is inspected annually as mandated by State law. HMD is also the lead enforcement agency for violations of underground storage tank laws and regulations (specifically, Chapter 6.7 of Division 20 of the California Health and Safety Code and Title 23 of Division 3 of the California Code of Regulations). The HMD-UST Program and the Site Assessment and Mitigation (SAM) Program within the Land Water Quality Division oversee UST removal activities. The primary function of the SAM program in UST removal activities is to provide regulatory oversight for the site assessment and mitigation of properties where unauthorized releases from UST systems have occurred.
