Underground Storage Tanks (USTs)

UST Performance Measures

EPA collects data from states and territories regarding UST performance measures. These data include information such as the number of active and closed tanks, releases confirmed, cleanups initiated and completed, facilities in compliance with UST requirements, and inspections. The reports below provide data in table format for all states, territories, and Indian country for the reporting period indicated.

Definitions

State and territory underground storage tank programs report to EPA periodically throughout the year with data on their UST performance, based on measures in the 2008 UST And LUST Performance Measures Definitions (PDF) (4 pp, 127 K). State and territories who implemented the revised 2015 UST regulation should refer to the 2018 UST And LUST Performance Measures Definitions (PDF) (8 pp, 96 K) ), which will be available for reporting after October 2018. EPA compiles the data for all states, territories, and Indian country and makes the data publicly available below.
