Underground Storage Tank (UST) Program


The Underground Storage Tank (UST) Program of the Los Angeles County Public Works, Environmental Programs Division (DPW EPD) permits and inspects underground storage tanks within the unincorporated areas (PDF, 52 KB) of Los Angeles County and 77 cities.

Los Angeles County Code (LACC), Title 11, Division 4, established the underground storage tank program in Los Angeles County in 1983. The Los Angeles County Underground Storage Tank Program's goal is to protect the public, the environment (air, soil and groundwater) and UST owners/operators by ensuring that UST facilities are permitted, designed/installed/modified, operating and eventually closed in compliance with local/state/federal requirements.

If you have any questions or need forms or other information you may contact us at our public counter, via mail or phone.
