Underground Storage Tank (UST) Program
New The Los Angeles Department of Public Works is launching a new website for contractors to submit Underground Storage Tank Testing Notifications. Please click here for details.
The Underground Storage Tank (UST) Program of the County of Los Angeles Department of Public Works, Environmental Programs Division (DPW EPD) permits and inspects underground storage tanks within the unincorporated areas (PDF, 32 KB) of Los Angeles County and 77 cities. The Unit regulates all unauthorized releases from underground storage tanks.

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.
