Operational Compliance Rates
Connecticut has reported 95% technical compliance rate for federal fiscal year 2025 compared to 89% for the previous year. Technical Compliance Rate (TCR) generally means that the UST systems at a facility have the proper equipment/procedures in place and are being properly operated and maintained in order to detect a release.
The average TRC in Region I was 59% for FY 2025. Please note that some states, including Connecticut, have operational requirements that are more stringent than the federal requirements. The table below compares TRC for the New England states for FY 2025. The figures are from the EPA FY 2025 End of Year Activity Report for the EPA Office of Underground Storage Tanks program (OUST).
