Semiannual Report OfUST Performance Measures
Mid Fiscal Year 2010 - As Of March 31, 2010

performance measures and makes the data publicly available. This data includes information such as the number of
active and closed tanks, releases reported, 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 Web site
www.epa.gov/oust/cat/camarchv.htm under Definitions.

requirements from 4/1/09 through 3/31/10. In accordance with EPA guidelines, states are allowed to report based on requirements
more stringent than the federal SOC requirements. Connecticut, Illinois, Michigan, Oklahoma, Rhode Island, Vermont, and
Wisconsin indicated they had done so, as described in the following section. 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.

These compliance rates indicate the percentage of facilities found to be in significant operational compliance (SOC) with federal UST
requirements from 4/1/09 through 3/31/10. In accordance with EPA guidelines, states are allowed to report based on requirements
more stringent than the federal SOC requirements. Connecticut, Illinois, Michigan, Oklahoma, Rhode Island, Vermont, and
Wisconsin indicated they had done so, as described in the following section. Furthermore, states have different approaches to
targeting inspections. For example, some states focus inspections on suspected non-compliant facilities, while other states conduct

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.
ILLINOIS
Release Detection: Testing
• Owner/operator must produce records within 30 minutes of arrival of inspector.
MICHIGAN
Release Detection
• Inventory control is required when using an automatic tank gauge (ATG).
OKLAHOMA
Release Prevention: Spill Prevention
• Ball floats not allowed as overfill prevention for any tank installed after 2001.
Release Prevention: Operation and Maintenance of Cathodic Protection
• Requires the previous 12 months of cathodic protection 60-day rectifier readings to be available for
review.
Release Prevention: Operation and Maintenance
• Monthly monitoring records not allowed to declare a lined tank is tight.
Release Detection: Testing
• Failed testing results must be submitted to the state within 7 days.
• Automatic tank gauges (ATGs) that cannot detect a 0.1 gallon per hour leak rate monthly are
required to have monthly inventory reconciliation in addition to ATG test.
• Statistical inventory control (SIR) cannot be used as sole method or release detection for piping.
• Annual function test of all mechanical and electronic line leak detectors, as well as dispenser and
tank sump sensors, is required by simulating a leak.
• Monthly alarm history and sensor status reports must be printed if used with interstitial monitoring
in lieu of annual line test.
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.
• Sacrificial anode systems are required to be tested every 3 years.
Release Detection: 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,
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
9
-------
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.
• 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 two 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

• 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.
