This list provides Underground Storage Tank (UST) site, tank, contact and Enforcement information for the approximately 45,000 commercial underground storage tanks (USTs) previously or currently registered in Connecticut, of which about 8,000 are still in use.
Compliance Details are the individual inspected compliance points that are referenced in a Field Notice of Violation (FNOV), Warning Letter, or Red Tag which can be issued by the Agency and contain information about how and when the compliance point has been resolved. The UST Site ID, Field NOV and Warning Letter numbers are included to cross-reference to the Enforcement Summary.

(There are 3 other related data sets: 1-Facility and Tank Details, 2-Contacts, and
3-Enforcement Summary.)

Annually, or when a UST is installed, removed, or altered, a notification form must be completed via EZFile 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 data set represents information reported after June 30, 2022 to the Department of Energy and Environmental Protection (CT DEEP), generally to the CT DEEP Dispatch Center, regarding releases of substances to the environment, generally through accidental spills.
The update frequeny on this data set is about once a month.

For current information related to releases reported to CT DEEP from July 1, 2022 to the present, go to Incident Reports for Releases Reported to CT DEEP July 1, 2022 to present at: https://connecticut.hazconnect.com/listincidentpublic.aspx.
For a dataset related to releases reported to CT DEEP from July 1, 1996 to June 30, 2022 refer to the CT Open Data dataset: https://data.ct.gov/Environment-and-Natural-Resources/Spill-Incidents-from-January-1-1996-to-June-30-202/wr2a-rnsg

This dataset is a snapshot of data from the live system that is updated periodically to provide to public users the download capabilities offered from the CT Open Data platform.
Connecticut General Statutes Section 22a-450 requires anyone who causes any discharge, spillage, uncontrolled loss, seepage or filtration of oil or petroleum or chemical liquids or solid, liquid or gaseous products, or hazardous wastes which poses a potential threat to human health or the environment to report that release to the CT DEEP. Reports of releases from other persons are also included in this dataset.

Examples of what may be included in a spill incident record includes: Administrative information (unique spill case number), Spill date/time, Location.,Spill source and cause, Material(s) and material type spilled.

Data limitations and factors to consider when using this data:
This data is limited to information about a spill incident as it was known at the time it was reported to CT DEEP. Although some data reflects updated information after the time of the initial notification, CT DEEP idoes not field check and verify all reported information. Therefore, information later determined to be incomplete or inaccurate may exist in this data set. There may also be spelling errors or other unintentionally inaccurate data that was transcribed in the spill incident report.

This dataset is a subset of records and information that may be available about releases that have occurred at specific locations. This dataset does not replace a full review of files publicly available either on-line and/or at CT DEEP’s Records Center.

For a complete review of agency records for this or other agency programs, you can perform your own search in our DEEP public file room (https://portal.ct.gov/DEEP/About/Environmental-Quality-Records-Records-Center-File-Room) located at 79 Elm Street, Hartford CT or at our DEEP Online Search Portal at: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/Home

- Reporting units of sample results [where 1 picoCurie (pCi) = 1 trillionth (1E-12) Curie (Ci)]:
• Air Samples are reported in pCi/m³.

- Data Quality Disclaimer:
This database is for informational use and is not a controlled quality database. Efforts have been made to ensure accuracy of data in the database; however, errors and omissions may occur.

Examples of potential errors include:
• Data entry errors.
• Lab results not reported for entry into the database.
• Missing results due to equipment failure or unable to retrieve samples due to lost or environmental hazards.
• Translation errors – the data has been migrated to newer data platforms numerous times, and each time there have been errors and data losses.

- Error results are the calculated uncertainty for the sample measurement results and are reported as +/-.

- Environmental Sample Records are from the year 1998 until present. Prior to 1998 results were stored in hardcopy, in a non-database format.

Requests for results from samples taken prior to 1998 or results subject to quality assurance are available from archived records and can be made through the DEEP Freedom of Information Act (FOIA) administrator at deep.foia@ct.gov. Information on
FOIA requests can be found on the DEEP website.
