What are the definitions for the UST performance measures?
The most current definitions for the UST performance measures are available on EPA's UST performance website
www.epa.gov/ust/ust-performance-measures under Definitions.
Where does EPA get the performance data?
Twice each year, EPA collects data from states regarding underground storage tank performance measures and
makes the data publicly available. EPA directly provides data on work in Indian country because the Agency
implements the program there. These data include information such as the number of active and closed petroleum
tanks and hazardous substance tanks, releases confirmed, cleanups initiated and completed, and inspections
conducted. The data also include the percentage of facilities in compliance with UST technical requirements,
operator training, financial responsibility, and walkthrough requirements. EPA compiles the data and presents it in
table format for all states and Indian country.

Where can I find performance data from previous years?
EPA's UST performance measures website www.epa.gov/ust/ust-performance-measures provides the current report,
as well as historical reports dating back to FY 2005. For older reports dating back to FY1988 (the first year EPA
reported UST data), please go to EPA's archive website archive.epa.gov/oust/cat-a/web/html/camarchv.html.
For more information, contact Susan Burnell of EPA's Office of Underground Storage Tanks at

Note: compliance measures track the percentage of recently inspected facilities in compliance with federal performance stand ards. States have
different approaches to targeting inspections (e.g., non-compliant facilities or random inspections). States report on the technical compliance rate (TCR)
measures based on state regulations updated since 2018 to be in compliance with the 2015 federal regulations. The TCR measures generally show
compliance for the last twelve months. However, as states transition to TCR, they will begin by reporting on a shorter timeframe, at most six months;
some will even be less due to compliance dates or the timeframe to enable system updates for tracking compliance.
Note: there are no tribal USTs in EPA Region 3.
1DNA = Data Not Available. States/EPA Regions (Indian country) that have passed the compliance dates for their updated regulations must begin
reporting TCR. CT, MA, NY, and AS did not report TCR at End-of-Year FY 2022 because they do not have updated regulations. MS has not updated its
data system to report TCR for End-of-Year FY 2022.
2States reporting based on requirements more stringent than the federal TCR requirements. See pages 6-9 for description of state regulations more
stringent than the federal TCR requirements.
3EPA Region 2 conducted inspections on behalf of VI during End-of-Year FY 2022. The TCR results for VI are based on these inspections.

financial responsibility requirements apply to petroleum USTs only, not hazardous substance USTs.
2DNA = Data Not Available. States/EPA Regions (Indian country) that have passed the compliance dates for their updated regulations
must begin reporting the additional compliance measures. MA, NY and AS did not report the additional compliance measures at End-
of-Year FY 2022 because they do not have updated regulations. MD's compliance date for walkthrough inspections began September
13, 2022. MS has not updated its data system to report the additional compliance measures for End-of-Year FY 2022.
3EPA Region 2 conducted inspections on behalf of VI during End-of-Year FY 2022. Vl's results for the additional compliance measures
