The Hazardous Materials Management Branch (HMMB)
The Hazardous Materials Management Branch (HMMB) 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) and Riverside County Ordinance 617. These regulations mandate the testing and frequent inspections of the UST facilities.
The goal of these regulations and the Riverside County UST Program 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 Riverside County
All UST testing notifications and/or UST test results can be submitted at the following email [email protected].
