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 SOC and others are reporting 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 (UST) 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.qov/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.
Who can I contact for more information?
Contact Susan Burnell of EPA's Office of Underground Storage Tanks at burnell.susan@epa.qov 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 compliancefor 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.
'DNA = Data Not Available. States/Regions (Indian country) that have passed the compliance dates for their updated regulations must
begin reporting TCR. However, AS, CNMI and EPA Regions had not conducted inspections and had no compliance data to report for Mid
Year 2019. The remaining states with DNA are working to update their reporting systems.
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.
States 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
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.

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 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

1DNA = Data Not Available. States/Regions (Indian country) that have passed the compliance dates for their updated
regulations must begin reporting the additional compliance measures. However, AS, CNMI and EPA Regions had not
conducted inspections and had no compliance data to report for Mid Year 2019. The remaining states with DNA are
working to update their reporting systems.
financial responsbility requirements apply to petroleum USTs only, not hazardous substance tank systems.
Note: there are no tribal USTs in EPA Region 3.
