Underground Storage Tank (UST) & CUPA Management
CCR Title 23 & Hazardous Materials Compliance for California Facilities
California's Certified Unified Program Agency (CUPA) framework consolidates oversight of underground storage tanks, hazardous materials, and hazardous waste into a single coordinated inspection and reporting program. For facilities that store petroleum products, chemicals, or other regulated substances underground, maintaining CUPA compliance is an ongoing operational obligation — not a one-time filing.
We provide complete risk management and environmental reporting services for facilities subject to California Code of Regulations (CCR) Title 23 and the Hazardous Materials Program under the California Health and Safety Code. Our team manages every layer of the program — from initial HMBP development and CERS electronic submissions to UST monitoring plan maintenance and CUPA inspection representation.
Our clients include gas stations, industrial facilities, fleet operations, agricultural storage sites, and any business operating underground storage tanks or maintaining reportable quantities of hazardous materials on site. We handle the regulatory complexity so you can focus on operations.
Core Technical Services
Hazardous Materials Business Plans (HMBP)
Annual chemical inventory tracking, Safety Data Sheet (SDS) compilation, emergency response plan design, and employee training records management. HMBPs are submitted electronically through the California Environmental Reporting System (CERS) and must be updated whenever chemical inventories change by a threshold amount or when new substances are introduced.
CERS Electronic Reporting
We manage, update, and submit all required data packages through the California Environmental Reporting System portal — including facility information, hazardous materials inventories, underground storage tank records, and annual certifications. Accurate and timely CERS submissions are critical to avoiding compliance deficiencies during CUPA inspections.
UST Permits & Title 23 Compliance
California Code of Regulations Title 23 governs underground storage tank operations, requiring monitoring plans, structural leak detection equipment configuration, annual line testing certifications, and spill bucket integrity testing. We develop and maintain all required UST compliance documentation and coordinate with the State Water Resources Control Board (SWRCB) and local CUPA agencies.
Facility Site Mapping
Accurate facility maps are mandatory components of both HMBP submissions and CUPA inspection packages. We prepare custom digital site drawings that clearly overlay chemical storage locations, emergency shutoff valves, storm drain locations, secondary containment boundaries, and the location of all safety equipment — meeting the specific format requirements of local CUPA agencies.
Employee Compliance Training & Inspection Support
California law requires annual employee safety training for facilities handling hazardous materials. We develop and deliver customized training programs, maintain training documentation, and provide physical on-site representation during multi-agency CUPA inspections — ensuring your team communicates accurately with inspectors and all records are immediately accessible.
Violation Resolution
When a CUPA inspection uncovers deficiencies, a rapid, documented response is required. We manage the correction of non-compliance findings, prepare proofs of correction with supporting documentation, and communicate directly with CUPA inspectors to close out violations on schedule and avoid escalating penalties.

Underground storage tank compliance centers on tank system permits, leak detection, monitoring and local CUPA oversight. A gasoline station may also need separate air district and vapor recovery support.
What to prepare for a consultation
Bring tank and piping records, monitoring plans, recent testing results, CERS records and CUPA inspection correspondence.
