Flyer: All UST Facilities must have a "Designated UST Operator"
A regulated “underground storage tank” is any one or combination of tanks, including piping connected thereto that is used for the storage of hazardous substances and that is substantially or totally beneath the surface of the ground. The vapor control components of UST systems are regulated by the EDC Air Quality Management District. Regulated USTs are permitted and inspected annually. Additional permitting and inspections are required for UST system installation, repairs and closures. California Code of Regulations Title 23, Section 2638 & 2643, requires that the UST Owner or Operator shall notify the Certified Unified Program Agency (CUPA) at least 48 hours in advance of conducting any installation, repair, replacement, calibration or certification of monitoring equipment and before conducting a tank or piping integrity test. For UST sites in El Dorado County, please notify our Department with either electronic and/or fax notification. Please email notifications to:firstname.lastname@example.org or fax notifications to: 530-295-2747

Every owner of an underground storage tank must register with the BOE and pay the underground storage tank maintenance fee for every gallon of petroleum product placed into the underground tank. If you own property where an underground storage tank is located, you are usually considered the owner of the underground storage tank. If you operate an underground storage tank but do not own it, you are not liable for the fee. An operator is defined as the person who controls or is responsible for the daily operation of the tank. Generally, if you lease an underground storage tank, you will be considered an operator, not an owner, unless your lease provides otherwise. The Underground Storage Tank Maintenance Fee Application can be found at California Board of Equalization.
