Why did EPA change the semiannual report and UST performance measures?
Effective with the 2019 mid-year semiannual UST performance report, EPA revised our semiannual report to reflect
changes in reporting by states, territories, and the District of Columbia (hereafter referred to as states). In October
2018, EPA updated our existing compliance performance measures and added new measures. Many of the changes
are the result of the 2015 federal UST regulation that increased emphasis on properly operating and maintaining UST
equipment. For more information, see EPA's technical compliance rate performance measures website
www.epa.qov/ust/technical-compliance-rate-tcr-performance-measures.

-------
Why are some states reporting significant operational compliance (SOC) and others are reporting
technical compliance rate (TCR)?
Through October 2021, states will report on either SOC measures or TCR measures, depending on their state's
regulatory compliance dates. After all states transition to reporting TCR measures, our semiannual UST
performance report will no longer include SOC performance measures.
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, since 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 significant operational compliance and those in
compliance with UST technical requirements, operator training, financial responsibility, and walk through
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 most current
report, as well as historical reports beginning with FY 1988, the first year EPA reported UST data. Reports are listed
beginning with the most recent first.
For more information, contact Susan Burnell of EPA's Office of Underground Storage Tanks at
burnell.susan@epa.gov or 202-564-0766.

Note: compliance measures track the percentage of recently-inspected facilities in compliance with federal performance standards. States have
different approaches to targeting inspections (i.e., non-compliant facilities or random inspections). EPA updated the compliance measures to
track compliance for provisions in the updated 2015 federal regulation. States will switch from tracking compliance against the significant
operational compliance (SOC) measures to the technical compliance rate (TCR) measures as they pass the compliance dates in the states' updated
regulations. The transition will continue through October 13, 2021. During the transition from SOC to TCR, this TCR table will list the states that
are still reporting SOC as N/A (not applicable). Seethe SOC chart for the compliance data for states listed as N/A on this table. The TCR
measures will ultimately show compliance for the last twelve months. 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 timeframe to enable system updates for tracking compliance.
Note: there are no tribal USTs in EPA Region 3.
1DNA = Data Not Available. States/Regions (Indian country) that have passed the compliance dates fortheir updated regulations must begin
reporting TCR. AS, CNMI, Ml and PR are working to update their reporting systems to fully report TCR. EPA Region 2 was not able to report TCR
at End-of-Year FY 2019 for Indian country.
2States reporting based on requirements more stringent than the federal TCR requirements. See pages 6-7 for description of state regulations
more stringent than the federal TCR requirements.

Note: compliance measures track the percentage of recently-inspected facilities in compliance with federal performance
standards. States have different approaches to targeting inspections (i.e., non-compliant facilities or random
inspections). EPA updated the compliance measures to track compliance for provisions in the updated 2015 federal
regulation. States will switch from tracking compliance against the significant operational compliance (SOC) measures to
the technical compliance rate (TCR) measures as they pass the compliance dates in the states' updated regulations. The
transition will continue through October 13, 2021. During the transition from SOC to TCR, this SOC table will list the
states that have switched to reporting TCR as N/A (not applicable). See the TCR table for the compliance data for states
listed as N/A on this table. The SOC measures show compliance for the last twelve months.
Note: Indian country falls under the federal regulation. See the TCR pages for compliance data in Indian country.
1States reporting based on requirements more stringent than the federal SOC requirements. See pages 10-11 for
description of state regulations more stringent than the federal SOC requirements.

o Tightness tests must be performed every 5 years after the installation of the ATG
until the tank has been installed for 20 years and every 2 years thereafter,
o Single-walled USTs installed for a period of 30 years have to be tightness tested
annually beginning in 2015.
o UST systems upgraded with interior lining and/or cathodic protections are not
required to have an ATG for 10 years after the upgrade. Tank tightness testing
must be conducted annually during these 10 years. After 10 years, an ATG is
required and tank tightness testing must be performed every 5 years until the
10

-------
tank has been installed for 20 years and then every 2 years thereafter. The results
of all tightness tests shall be maintained for 3 years beyond the life of the facility,
o Tightness testing of UST and piping interstitial spaces is required when a system
has been installed for a period of 20 years, and every 2 years thereafter.
• Groundwater or vapor monitoring not accepted as a method of leak detection.
• SIR not accepted.
TEXAS
Release Detection:
• All retail locations are required to do inventory control and maintain records. Any
exceedance beyond one month must be reported to TCEQ.
VERMONT
Release Prevention: Operation and Maintenance of Cathodic Protection
• Lining not allowed unless with impressed current.
Release Detection: Method Presence and Performance Requirements
• Weekly monitoring required for tank and piping. Records must be available for the 2 most

annual TTT.
WISCONSIN
Release Prevention: Operation and Maintenance of Cathodic Protection
• Require annual cathodic protection test.
Release Prevention: Spill Prevention
• Require USTs to be equipped with overfill prevention equipment that will operate as
follows (NFPA 30-2.6.1.4 - 2000 and 2003 version):
o Automatically shut off the flow of liquid into the tank when the tank is no more
than 95% full;
o Alert the transfer operator when the tank is no more than 90% full by restricting
the flow of liquid into the tank or triggering the high-level alarm; and,
o Other methods approved by the authority having jurisdiction.
Release Detection: Testing
• Require NFPA 30A09.2.1 (2000 and 2003 versions). Accurate daily inventory records shall
be maintained and reconciled for all liquid fuel storage tanks for indication of possible
leakage from tanks or piping. The records shall be kept on the premises or shall be made
available to the authority having jurisdiction for the inspection within 24 hours of a
written or verbal request. The records shall include, as a minimum and by product, daily
reconciliation between sales, use, receipts, and inventory on hand. If there is more than
one storage system serving an individual pump or dispensing device for any product, the
reconciliation shall be maintained separately for each system.
Release Detection: Deferment
• No exclusion or deferment for "remote" emergency generator tanks.
Other
• Require annual permit to operate that includes verification of financial responsibility.
