- Annual Report Of UST Performance Measures End Of Fiscal Year 2009 – As Of September 30, 2009 Where does EPA get th e 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

. 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 com piles the data and present s 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

. 

## What is in th e end of f iscal y ear (FY) 2009 report ?

## How did the UST program’s performance compare with its goals? FY 2009 UST Program Goal FY 2009 UST Program Performance Complete 12,250 cleanups, including 30 in Indian country Exceeded the FY 2009 goal by completing 12, 944 cleanups, inclu ding 49 in Indian country Achieve a significant operational compliance rate of 65 percent Exceeded the FY 2009 goal by achieving a significant operational compliance rate of 66.4 percent Decrease newly

- confirmed releases to fewer than 9,000 Exceeded the FY 2009 goal by decreasing newly

- confirmed releases to 7,168 

## What other highlights are included in the end of FY 2009 report ?

• There are 611,449 active USTs (at approximately 223,000 sites) which are regulated by the UST regulations
• Since the 1984 ince ption of the UST program , 1,718,833 substandard USTs have been closed • Of the 488,496 leaks reported since the beginning of the UST program, 388,331 (or 79. 5 percent) have been cleaned up, leaving a backlog of 100,165 remaining to be cleaned up
• 9 5,675 on - site inspections at federally

- regulated UST facilities were conducted between October 2008 and September 2009 ; of those:

– 9 5,296 were conducted by states, territories, and third

-party inspectors

– 379 were conducted by EPA and credentialed tribal inspecto rs in Indian countryOffice of Underground Storage Tanks, Washington, D.C. 20460 December 2009 www.epa.gov/oust 

## Where can I find performance data from previous years? EPA’s Web site www.epa.gov/oust/cat/camarchv.htm provides the most current report, as well as historical reports beginning with FY 1988, the first year reports were developed. Reports are listed beginning with the most recent first.

In accordance with EPA guidelines, states are allowed to report based on requirements more stringent than the federal SOC requirements. Connecticut, Illinois, Michigan, Rhode Island, Vermont, and Wisconsin indicated they had done so, as described in the next page. 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.

## 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). 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 ar e 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). • The automatic tank gauge (ATG) has to be checked monthly and have an annual test conducted. • 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 in stalled 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 fo r 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. • Groundwater or vapor monito ring 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) no t 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 preven tion 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 sale s, 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 maintain ed 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.Region/
