Note: This dataset is no longer being updated. As of 2020, Aboveground Storage Tank data is captured in the CDPH Environmental Permits dataset and Underground Storage Tank data is available from the Office of the Illinois State Fire Marshal. This dataset contains Aboveground Storage Tank (AST) and Underground Storage Tank (UST) information from the Department of Public Health’s (CDPH) Tank Asset Database. The Tank Asset Database contains tank information from CDPH AST and UST permit applications as well as UST records imported from the historic Department of Environment (DOE) database. This dataset also includes AST records from the historic DOE and pre-1992 UST records from the Building Department.

This list provides Underground Storage Tank (UST) site, tank, contact and Enforcement information for the approximately 45,000 commercial underground storage tanks (USTs) previously and currently registered in Connecticut, of which about 8,000 are still in use. (There are 3 other related data sets: 1-Contact Details 2-Enforcement Summary, and 3-Compliance Details)

Annually, or when a UST is installed, removed, or altered, a notification form must be completed via EZFile (see link) and submitted to CT DEEP. Notification is required for non-residential underground storage tanks, including those for oil, petroleum and chemical liquids, as well as residential home heating oil tanks serving five or more units. See online at: https://www.ct.gov/deep/cwp/view.asp?q=322600

The underground storage tank regulations and the Connecticut underground storage tank enforcement program have been in effect since November 1985. This list is based on notification information submitted by the public since 1985, and is updated weekly. This list contains information on both active and on non-active USTs, as well as federally regulated and state regulated USTs.

Factors to Consider When Using this data:

-Not every required notification form is submitted to the DEEP. We can only enter the information we receive.

-We know there are errors in the data although we strive to minimize them. Error examples may include: notification forms completed incorrectly by the owner/operator, data entry errors, duplicate site information, misspelled names and addresses and/or missing data.

This list provides information about releases from federally regulated Underground Storage Tank (UST) Systems that have been, and are scheduled to be, reported to the US Environmental Protection Agency (EPA) by the CT DEEP. There are approximately 3600 releases from federally regulated USTs on this list. Federally regulated USTs include USTs containing heating fuel for resale purposes and USTs that contain gasoline, diesel, kerosene, and waste oil. To learn more about federally regulated USTs please see the EPA's UST website (https://www.epa.gov/ust/learn-about-underground-storage-tanks-usts). This dataset is a subset of records and information that may be available about releases from federally regulated USTs that have occurred at specific locations. This dataset does not replace a full review of files publicly available either using the DEEP on-line Public Portal (https://filings.deep.ct.gov/DEEPDocumentSearchPortal/) and/or at the DEEP Record Center File Room (https://portal.ct.gov/DEEP/About/Environmental-Quality-Records-Records-Center-File-Room). ‒ This list does not contain releases from non-federally regulated USTs (i.e. releases from residential heating fuel USTs). ‒ Not every type of release from a federally regulated UST System is required to be reported to the EPA. ‒ Not every release from a federally UST System is reported to the DEEP. We can only report the information we receive. ‒ We know there may be errors in the data although we strive to minimize them. Examples of errors may include: misspelled or incomplete addresses and/or missing data. If errors are found please contact the program unit using the following email address: DEEP.Leakingust@ct.gov .

Below is an explanation of the data along with some features that are available on this map (description is also provided in the "Getting Started" widget of the application).A variety of different colored circles appear throughout the map. They represent sites that are associated with the following programs:1) Department of Toxic Substances Control (DTSC) sites:a) Historical Inactive - Identifies sites from an older database that are non-active sites where, through a Preliminary Endangerment Assessment (PEA) or other evaluation, DTSC has determined that a removal or remedial action or further extensive investigation is required.b) School Cleanup - Identifies proposed and existing school sites that are being evaluated by DTSC for possible hazardous materials contamination. School sites are further defined as “Cleanup”, where remedial actions are or have occurred.c) School Evaluation - Identifies proposed and existing school sites that are being evaluated by DTSC for possible hazardous materials contamination. School sites are further defined as “Evaluation”, where further investigation is needed.d) Corrective Action - Investigation or cleanup activities at Resource Conservation and Recovery Act (RCRA) or state-only hazardous waste facilities (that were required to obtain a permit or have received a hazardous waste facility permit from DTSC or U.S. EPA).e) State Response - Identifies confirmed release sites where DTSC is involved in remediation, either in a lead or oversight capacity. These confirmed release sites are generally high-priority and high potential risk.f) Evaluation - Identifies suspected, but unconfirmed, contaminated sites that need or have gone through a limited investigation and assessment process.g) Tiered Permit - A corrective action cleanup project on a hazardous waste facility that either was eligible to treat or permitted to treat waste under the Tiered Permitting system.2) State Water Board or DTSC sites:a) Leaking Underground Storage Tank (LUST) Cleanup - Includes all Underground Storage Tank (UST) sites that have had an unauthorized release (i.e. leak or spill) of a hazardous substance, usually fuel hydrocarbons, and are being (or have been) cleaned up. These sites are regulated under the State Water Board's UST Cleanup Program and/or similar programs conducted by each of the nine Regional Water Boards or Local Oversight Programs.b) Cleanup Program - Includes all "non-federally owned" sites that are regulated under the State Water Board's Site Cleanup Program and/or similar programs conducted by each of the nine Regional Water Boards. Cleanup Program Sites are also commonly referred to as "Site Cleanup Program sites".c) Voluntary Cleanup - Identifies sites with either confirmed or unconfirmed releases, and the project proponents have requested that the State Water Board or DTSC oversee evaluation, investigation, and/or cleanup activities and have agreed to provide coverage for the lead agency’s costs.3) Othera) Permitted Tanks - The "Permitted Tanks" data set includes Facilities that are associated with permitted underground storage tanks from the California Environmental Reporting System (CERS) database. The CERS data consists of current and recently closed permitted underground storage tank (UST) facilities information provided to CERS by Certified Unified Program Agencies (CUPAs).*Note: Underground Storage Tank Cleanup and Cleanup Program project records are pulled from the State Water Board's GeoTracker database. The Permitted Tanks information was obtained from California EPA’s California Environmental Reporting System (CERS) database. All other project records were obtained from DTSC's EnviroStor database. Program descriptions come from DTSC’s EnviroStor Glossary of Terms and the State Water Board’s GeoTracker Site/Facility Type Definitions. The information associated with these records was last updated in the application on 4/24/2023.

This dataset represents the geographic locations of active, registered Underground Storage Tank facilities. Features are referred to as "facilities." This data is extracted from the Tank Inventory Management System (TIMS) database.

Tracks underground storage tanks (UST) site location, site owners, tanks, Risk-Based Corrective Action (RBCA), site classification and remediation; and the current status of UST & Leaking UST sites.

This data represents sites where there has been a release of petroleum to the soil and/or groundwater, from an Underground Storage Tank (UST) system. Features are referred to as "incidents" when an incident number has been assigned. This data is extracted from the Regional Underground Storage Tank (RUST) database.

Underground storage tank (UST) sites which store petroleum in Iowa. Includes sites which have been reported to DNR, and have active or removed underground storage tanks . This coverage includes all of the UST sites. Efforts to improve the coverage are ongoing. (A separate coverage has been created for Leaking Underground Storage Tank sites where petroleum contamination has been found.)

Access point locations for regulated Underground Storage Tank (UST) systems within Indiana, and is provided by personnel of Indiana Department of Environmental Management, Office of Land Quality (IDEM, OLQ). Attributes include regulatory identification numbers (IDEM), site names, IDEM program and sub-program designation, address information, and data collection dates by IDEM personnel.An underground storage tank (UST) system is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. The Office of Land Quality (OLQ) does not regulate every type of storage tank. OLQ regulations apply only to UST systems that store petroleum or certain hazardous substances. OLQ helps UST owners and operators understand the regulations in order to encourage and promote voluntary compliance.The Underground Storage Tank (UST) program is responsible for registering all regulated underground storage tanks and assures that all regulated underground storage tanks meet Indiana's requirements for release detection, spill and overflow prevention and corrosion protection, and to insure that tanks not meeting those requirements are properly closed. The UST program also assures that these protection systems are operated and maintained properly.Leaking Tanks - When a regulated UST has a leak or spill, OLQ is responsible for ensuring adequate investigation and cleanup of the resulting contamination. To guarantee that that a leaking tank and its affected area are properly addressed, state and federal laws require owners and operators of UST systems to have financial responsibility. OLQ maintains the Excess Liability Trust Fund (ELTF) to provide a mechanism for the reimbursement of money spent by UST owners and operators on the cleanup of petroleum released from USTs. It also provides the federally mandated financial assurance for owners and operators of petroleum USTs and a source of money for the indemnification of third parties.

Subtitle I of the Resource Conservation and Recovery Act, as amended by the Hazardous Waste Disposal Act of 1984, brought underground storage tanks (USTs) under federal regulation. EPA implements the underground storage tank (UST) program in Indian country, providing support to tribal governments to prevent and clean up petroleum releases from USTs. The UST program in Indian country includes marketers and nonretail facilities that have USTs. Marketers include retail facilities such as gas stations and convenience stores that sell petroleum products. Non-retail facilities include those that do not sell petroleum products, but may rely on their own supply of gasoline or diesel for taxis, buses, limousines, trucks, vans, boats, heavy equipment, or a wide range of other vehicles. Of the more than 560 federally recognized tribes about 200 have federally-regulated underground storage tanks on their lands. Of those 200 tribes, over half have 10 or fewer active underground storage tanks. About 20 tribes have 30 or more underground storage tanks. Data on sites managed by this program is assembled by the EPA Regional Offices and varies from region to region in scope and content. Not all regions include Indian Nations. Publicly available data is limited to Excel spreadsheets, but regional contacts are also available to answer questions about the data. Data is updated in May and November of each year.

The EDR Recovered Government Archive Leaking Underground Storage Tank database provides a list of LUST incidents derived from historical databases and includes many records that no longer appear in current government lists. Compiled from Records formerly available from the Department of Environmental Protection in Florida.

Records of Seattle Fire Department (SFD) permits related to decommissioning of a residential heating oil tank, permit code 6103. A record with incomplete tank info indicates that the required follow-up report has not been received by SFD. Please note that SFD records begin in 1996 when state requirement was introduced. Decommissioning of a residential heating oil tank might have occurred prior to 1996, in which SFD will not have a record. Commercial UST records can be requested through City Public Records Request Center at http://www.seattle.gov/public-records/public-records-request-center

This dataset contains Aboveground Storage Tank (AST) and Underground Storage Tank (UST) information from the Department of Public Health’s (CDPH) Tank Asset Database. The Tank Asset Database contains tank information from CDPH AST and UST permit applications as well as UST records imported from the historic Department of Environment (DOE) database. This dataset also includes AST records from the historic DOE and pre-1992 UST records from the Building Department. Data fields requiring description are detailed below. MAPPED LOCATION: Contains latitude/longitude coordinates of the site as determined through the Chicago Open Data Portal’s geocoding engine. In instances where the facility address is a range, the lower number (the value in the “Street Number From” column) is used for geocoding. For example, for the range address 1000-1005 S Wabash Ave, the Mapped Location would be the coordinates for 1000 S Wabash Ave. TANK TYPE: Specifies if the asset is an Underground Storage Tank or an Aboveground Storage Tank.
FACILITY ID: This is the unique identifier of the facility. A UST Facility ID that is seven digits long and begins with the number ‘2’ is a Facility ID assigned by the Office of the State Fire Marshall (OSFM). All other IDs were assigned by the DOE or CDPH based on the facility address.
OWNER: The owner of record for the tank. For State-regulated USTs, this is the owner registered with the OSFM. FACILITY NAME: This is the name given to the facility. This is usually the company/owner name, building name or address.
TANK ID: This is a numeric ID that uniquely identifies a particular tank at the facility. TANK MATERIAL: Specifies the type of material the tank is made of. TANK PRODUCT: Specifies the type of product stored in the tank.
TANK CAPACITY: This is the storage volume of the tank in gallons. INSTALLATION DATE: The date the tank was installed at the facility if known. For some records, this information is in the COMMENTS column. REMOVAL DATE: The date the tank was removed from the facility if known. For some records, this information is in the COMMENTS column. LAST USED DATE: The date the tank was last in service if known. For some records, this information is in the COMMENTS column. COMMENT: Contains additional information on the tank that may include supplemental location information; field observations; removal, abandonment, or last used dates; permitting notes; and other miscellaneous information. DATA SOURCE: The city department that collected the data.

Abstract

US EPA's UST Finder data is a national composite of leaking underground storage tanks, underground storage tank facilities, and underground storage tanks as of 2018-2021. This data contains information about, and locations of, leaking underground storage tanks, underground storage tank facilities, and underground storage tanks. Data is current as of 2018-2021. Data was collected from state sources and standardized into a national profile by EPA's Office of Underground Storage Tanks, Office of Research and Development, and the Association of State and Territorial Solid Waste Management Officials.

This is a list of sites from the “SASU (Site Assessment and Support Unit) Case Management” System, which is also known as the LUST Database. Sites on this list include, but are not limited to: sites with known releases from regulated Underground Storage Tank (UST) systems, sites with releases from non-regulated UST system sources, releases from non-UST related sources, sites with potential releases for which impacts or sources of release were not confirmed at time of entry into the system.

The “SASU Case Management” system was initially developed in the late 1980’s/early 1990’s to track sites that the Site Assessment and Support Unit (SASU) worked on. At the time SASU contained the LUST Program. Overtime the “SASU Case Management” System evolved to primarily track releases from regulated Leaking Underground Storage Tanks (LUST) and is currently maintained by the DEEP’s Corrective Action Unit (CAU).

This dataset does not replace a full review of other environmental datasets available through CT Open Data, HazConnect (https://connecticut.hazconnect.com/listincidentpublic.aspx), files publicly available either using the DEEP on-line Public Portal (https://filings.deep.ct.gov/DEEPDocumentSearchPortal/) and/or at the DEEP Record Center File Room (https://portal.ct.gov/DEEP/About/Environmental-Quality-Records-Records-Center-File-Room).

We know there may be errors in the data although we strive to minimize them. Examples of errors may include: misspelled or incomplete addresses and/or missing data.

A separate dataset ( https://data.ct.gov/Environment-and-Natural-Resources/List-of-Contaminated-or-Potentially-Contaminated-S/u76p-weqj/data ) is also published for: List of Contaminated or Potentially Contaminated Sites - Remediation Division. The two database systems are maintained by different Divisions within the agency. There may be sites in both databases due to an overlap in responsibilities of the two Divisions.

The ISIS Web reporting portal provides a selection of standard reports for Cleanup Sites, Brownfields, Underground Storage Tanks(UST), Leaking Underground Storage Tanks, and Environmental Covenants Registry.

This dashboard brings together underground storage tank records from older paper sources as well as more recent inspection records. It allows for searches by address to retrieve all known records, as well as the ability to see a whole street. Please read the following caveats: - Records have been aligned with current addresses, with some attempts made at fixing spelling errors, disambiguation, road re-naming, etc. However, about 25% of all records are not aligned to a current address and may contain relevant information to tanks still in the ground. - There is no guarantee that all records are included or that they form a complete inventory of all tanks as some may have been damaged or lost. The absence of records should not be interpreted as the absence of a tank.

While the EPA regulates only underground petroleum storage tanks, the State of New Mexico additionally regulates aboveground petroleum storage tanks. This map shows only active facilities.
