Underground Storage Tank (UST) Program
Information – Background, Snapshot, HighlightsThe goal of the UST Program is to protect public health, the environment and groundwater. To accomplish this goal, ACDEH Certified Unified Program Agency (CUPA) ensures that businesses and facilities with ongoing UST operations are properly permitted and meet the monitoring requirements applicable to their type of equipment. This is accomplished by:
- Conducting annual inspections at ACDEH regulated businesses as required by State law.
- Review and approve all electronic submissions regarding UST installations, repairs, upgrades and removals through CERS.
- Conduct installation, repair, and upgrade inspections.
To notify ACDEH at least 48 hours prior to monitoring certifications, secondary containment testing, etc. email the UST program at DEHUST@acgov.org with the facility name, testing company, type of inspection and date and time of the requested inspection.The California Health and Safety Code (H&SC) and the California Code of Regulations (CCR) require that a UST owner or operator must obtain a permit to install, upgrade or repair a UST. ACDEH is the agency that issues UST install, upgrade or repair permits for facilities within our jurisdiction. Most installations, upgrades and repairs require a permit.
UST Upgrade or Repair Actions that Require a Permit:The following list provides examples of some common upgrade or repair actions that require a permit:
- Tank sump, and under dispenser containment (UDC) install, upgrade or repair.
- Any piping upgrade or repair (including relocation of existing pipes or installation of additional piping).
- Monitoring system panel upgrade, replacement or repair involving reprogramming (e.g. software upgrade that includes re-wiring or re-programming).
- Overfill prevention equipment modifications or upgrades.
- Like-for-like replacement (same make and model) of sensors, drop tube, fuel turbines, mechanical line leak detectors, or flex connectors (if inside a sump or UDC).
- Software upgrades of the monitoring system panel that do not require any re-wiring, reprogramming or restarting.
**Emergency Alert** Power Safety Power Shutoff (PSPS) Affected USTs
During a PG&E Public Safety Power Shutoff (PSPS), an Underground Storage Tank (UST) monitoring system may lose its power source and shut down erasing the alarm history data and system setup. After the monitoring system panel regains power a Cold Start is required to ensure UST monitoring systems are functioning correctly and properly programmed. A business with a UST needing a Cold Start are required to do the following:
- Notify Alameda County Department of Environmental Heath (ACDEH) Certified Unified Program Agency (CUPA) within 3 days after a Cold Start.
- Obtain a permit from ACDEH CUPA for the Cold Start.
- Provide ACDEH CUPA a notice of the time and date of testing at least 48 hours prior to monitoring certification by email to DEHUST@acgov.org.
- Submit monitoring system certification results to ACDEH CUPA within 30 days of testing.
When there is a Cold Start as the result of a PG&E PSPS, ACDEH CUPA will waive the standard permit and fees and will only charge the Ordinance-approved hourly rate for inspector time. However, failure to notify ACDEH CUPA of a Cold Start within the required time frame and obtain the appropriate permit will result in a violation and the requirement to complete all permit conditions including payment of full permit fees.
TIP: To prevent a Cold Start, test the battery in the UST monitoring panel annually and replace as necessary.
Underground Storage Tank (UST) - RemovalThe California Health and Safety Code (H&SC), the California Code of Regulations (CCR) require that a UST owner or operator must obtain a permit to remove a UST. ACDEH CUPA issues UST removal permits for facilities within our jurisdiction.
UST Removal Requirements:
The following is a general overview of UST removal requirements.
- Submittal and approval of UST removal application, supporting forms and permit fee.
- Removal and proper disposal of any residual liquid, solids, or sludge within the UST system.
- All soil and water sampling meets ACDEH requirements.
- ACDEH observation / inspection of the UST removal and soil sampling (48 hour notification required).
- Submittal of rinsate manifest, tank disposal documentation, soil and water sample lab analysis, and soil stockpile disposal documentation.
- UST Regulations (CCR, Title 23, Chapter 16) Effective October 1, 2018
- Underground Storage of Hazardous Substance (Health & Safety Code Chapter 6.7) Amended and Effective January 1, 2019
