Semiannual Report OfUST Performance Measures
Mid Fiscal Year 2018 (October 1, 2017 - March 31, 2018)

Where does EPA get the performance data?

Twice each year, EPA collects data from states and territories 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 for those sites. 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. EPA compiles the data and presents it in table format for all states, territories, and
Indian country.

What are the UST performance measures?

The most current definitions for the UST performance measures are available on EPA's website
www.epa.gov/ust/ust-performance-measures under Definitions.

What is in the mid fiscal year (FY) 2018 report?

These compliance rates indicate the percent of recently-inspected facilities in significant operational compliance (SOC) with federal UST
requirements from 4/1/17 through 3/31/18. According to EPA guidelines, states are allowed to report based on requirements more stringent
than the federal SOC requirements. States identified with footnote1 indicated they had done so, as described on pages 9 and 10.
Furthermore, states have different approaches to targeting inspections. For example, some states focus inspections on suspected non-
compliant facilities, while other states conduct random inspections.

1	States reporting based on requirements more stringent than the federal SOC requirements.

2	DNA = Data Not Available. Puerto Rico was unable to report mid-year FY18 data.

These compliance rates indicate the percentage of recently-inspected facilities in significant operational compliance (SOC) with federal
UST requirements from 4/1/17 through 3/31/18. According to EPA guidelines, states are allowed to report based on requirements more
stringent than the federal SOC requirements. States identified with footnotel indicated they had done so, as described on pages 9 and 10.
Furthermore, states have different approaches to targeting inspections. For example, some states focus inspections on suspected non-
compliant facilities, while other states conduct random inspections.

1 States reporting based on requirements more stringent than the federal SOC requirements.

3	DNA = Data Not Available because no inspections were conducted within the last 12 months.

4	N/A = Not Applicable. There are no tribal USTs in EPA Region 3.

-------
States With Requirements More Stringent Than The Federal
Significant Operational Compliance Requirements

CONNECTICUT

Release Prevention: Operation and Maintenance of Cathodic Protection

•	Lining not allowed.

Release Detection: Testing

•	Tanks and piping require weekly and monthly monitoring for releases and records must be available
(for 2 of the most recent consecutive months and for 8 of the last 12 months).

•	Statistical Inventory Reconciliation (SIR) not allowed as a stand-alone method.

IDAHO

Release Prevention: Operation and Maintenance of Cathodic Protection

•	Three 60-day rectifier inspection checks are required.

•	Two three-year system checks are required for impressed current and galvanic.

Release Detection: Testing

•	Records required for the past 12 months.

Other

•	Percent of UST facilities in compliance with both release detection and release prevention also
factors in financial responsibility and EPAct requirements, such as operator training and secondary
containment.

ILLINOIS

Release Detection: Testing

•	Owner/operator must produce records within 30 minutes of arrival of inspector.

MICHIGAN

Release Detection: Required Methods

•	Owners/operators must have inventory control plus another method of release detection.

MISSOURI

Release Prevention: Cathodic Protection

•	All metal components in contact with any electrolyte must be cathodically protected.

NEBRASKA

Release Prevention: Cathodic Protection

•	All metal components in contact with any electrolyte must be cathodically protected.

Release Prevention: Reporting

•	Owner/operator must submit monthly inventory monitoring reports to the state.

Release Prevention: Temporarily Closed Tanks

•	Owner/operator must permanently close USTs that have been in temporary closed status for more
than one year.

RHODE ISLAND

Release Prevention: Operation and Maintenance

•	All tanks and piping are required to be tightness tested after a repair. No exemptions.

Release Prevention: Operation and Maintenance of Cathodic Protection

•	Impressed current cathodic protection systems are required to be tested every 2 years.

Release Detection: Monitoring and Testing

•	Records required for the past 36 months.

•	Inventory control is required for all tanks (single-walled and double-walled).

•	Tightness testing schedule is different than the federal requirement; it depends on the type of tank.

o Tank tightness must be performed on all single walled tanks.

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.

9


-------
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.

•	SIR not accepted.

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 recent
consecutive months and for 8 of the last 12 months.

Release Detection: Testing

•	Inventory control /Tank Tightness Testing (TTT) not allowed as a release detection method after
6/30/98.

•	Manual Tank Gauge (MTG) allowed alone up to 550 gallons; 551-1,000 gallons, MTG with 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.

States use different approaches to delivery prohibition. For example, certain states issue a notice of intent before actually issuing a delivery
prohibition (i.e., some states forgo delivery prohibition issuance for facilities that come into compliance). In addition, some states prohibit
deliveries primarily for registration violations.
