Underground Storage Tanks

             

An underground storage tank system is defined as any one, or combination of tanks, including connected piping and ancillary equipment, that is used for the storage of hazardous substances, where at least ten percent of the Underground Storage Tank system’s volume is located beneath the surface of the ground or is enclosed below earthen materials.

The Tulare County Environmental Health Division regulates and oversees the inspections of constructions, repairs, upgrades, system operation and removal of underground storage tank (UST) systems.

A permit to operate a UST system is required per California Code of Regulations Title 23, Division 3, Chapter 16, California Health and Safety Code Section (25280 – 25299.8). These regulations mandate the testing and frequent inspections of the UST facilities.

The goal of these regulations is to protect waters of the state from discharges of hazardous substances from underground storage tanks. This program also provides a mechanism to educate UST owners/operators, enforce the regulations and to pursue non-compliant facilities through the legal system.

The HMMB established several central area offices that can conduct and provide the following services:

  • Conduct routine inspections of all regulated fuel facilities
  • Approve all electronic submissions regarding UST installations, repairs, upgrades and removals
  • Conduct installation, repair, and upgrade inspections within Tulare County
