Dataset Description:
We know there are errors in the data although we strive to minimize them. Examples include:
• Manifests completed incorrectly by the generator or the transporter - data was entered based on the incorrect information. We can only enter the information we receive.
• Data entry errors – we now have QA/QC procedures in place to prevent or catch and fix a lot of these.
• Historically there are multiple records of the same generator. Each variation in spelling in name or address generated a separate handler record. We have worked to minimize these but many remain. The good news is that as long as they all have the same EPA ID they will all show up in your search results.
• Handlers provide erroneous data to obtain an EPA ID - data entry was based on erroneous information. Examples include incorrect or bogus addresses and names. There are also a lot of MISSPELLED NAMES AND ADDRESSES!
• Missing manifests – Not every required manifest gets submitted to DEEP. Also, of the more than 100,000 paper manifests we receive each year, some were incorrectly handled and never entered.
• Missing data – we know that the records for approximately 25 boxes of manifests, mostly prior to 1985 were lost from the database in the 1980’s.
• Translation errors – the data has been migrated to newer data platforms numerous times, and each time there have been errors and data losses.
• Wastes incorrectly entered – mostly due to complex names that were difficult to spell, or typos in quantities or units of measure.

Since Summer 2019, scanned images of manifest hardcopies may be viewed at the DEEP Document Online Search Portal: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/

Description of Dataset:
This data set represents information reported between July 1, 1996 and 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. For 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, 2022 to recent refer to the CT Open Data dataset: https://data.ct.gov/Environment-and-Natural-Resources/Spill-Incidents-from-July-1-2022-to-Recent-for-Dow/ffju-s5c5

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. Quantity spilled. Measurement units. Surface water bodies affected.

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 is unable to 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 located at 79 Elm Street, Hartford CT or at our DEEP Online Search Portal at: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/Home .

If errors are found or there are questions about the data, please contact the program unit using the following email address: DEEP.SpillsDocs@ct.gov

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.

Data to create the List of Contaminated or Potentially Contaminated Sites - Remediation Division is from historical program information or from new program applications and filings. More information regarding the generation of this list can be found at: https://portal.ct.gov/DEEP/Remediation--Site-Clean-Up/List-of-Contaminated-or-Potentially-Contaminated-Sites-in-Connecticut

A seperate dataset is published for: List of Contaminated Sites or Potentially Contaminated - SASU Case Management System and provide a list of Leaking Underground Storage Tank Sites. 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. https://data.ct.gov/Environment-and-Natural-Resources/List-of-Contaminated-or-Potentially-Contaminated-S/77ya-7twa

The data is updated when documents are received for responsible parties conducting site remediation. For more information regarding the individual remedial programs visit: https://portal.ct.gov/DEEP/Remediation--Site-Clean-Up/Remediation-Site-Clean-Up

Those seeking additional information about information contained in this dataset may use the DEEP FOIA Process:
https://portal.ct.gov/DEEP/About/FOIA-Requests

Each Row represents a Remediation project (Property Transfer, Brownfield, Enforcement, Federal Remediation, State Remediation, Landfill Monitoring, RCRA Corrective Action, and Voluntary). Data to compile the list was gathered for each site from information provided to DEEP for requirements within each program. Sites may be in multiple Remediation programs and therefore may be listed more than once. Some sites have been fully cleaned up while others have limited information about the environmental conditions. The list includes only sites that been reported to DEEP or EPA.

Dataset Description Outline (5 sections)

• INTRODUCTION

• WHY USE THE CONNECTICUT OPEN DATA PORTAL MANIFEST METADATA DATASET INSTEAD OF THE DEEP DOCUMENT ONLINE SEARCH PORTAL ITSELF?

• WHAT MANIFESTS ARE INCLUDED IN DEEP’S MANIFEST PERMANENT RECORDS ARE ALSO AVAILABLE VIA THE DEEP DOCUMENT SEARCH PORTAL AND CT OPEN DATA?

• HOW DOES THE PORTAL MANIFEST METADATA DATASET RELATE TO THE OTHER TWO MANIFEST DATASETS PUBLISHED IN CT OPEN DATA?

• IMPORTANT NOTES

INTRODUCTION
• All of DEEP’s paper hazardous waste manifest records were recently scanned and “indexed”. • Indexing consisted of 6 basic pieces of information or “metadata” taken from each manifest about the Generator and stored with the scanned image. The metadata enables searches by: Site Town, Site Address, Generator Name, Generator ID Number, Manifest ID Number and Date of Shipment.
• All of the metadata and scanned images are available electronically via DEEP’s Document Online Search Portal at: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/
• Therefore, it is no longer necessary to visit the DEEP Records Center in Hartford for manifest records or information.
• This CT Data dataset “Hazardous Waste Portal Manifest Metadata” (or “Portal Manifest Metadata”) was copied from the DEEP Document Online Search Portal, and includes only the metadata – no images.

WHY USE THE CONNECTICUT OPEN DATA PORTAL MANIFEST METADATA DATASET INSTEAD OF THE DEEP DOCUMENT ONLINE SEARCH PORTAL ITSELF?
The Portal Manifest Metadata is a good search tool to use along with the Portal. Searching the Portal Manifest Metadata can provide the following advantages over searching the Portal:
• faster searches, especially for “large searches” - those with a large number of search returns unlimited number of search returns (Portal is limited to 500);
• larger display of search returns;
• search returns can be sorted and filtered online in CT Data; and
• search returns and the entire dataset can be downloaded from CT Data and used offline (e.g. download to Excel format)
• metadata from searches can be copied from CT Data and pasted into the Portal search fields to quickly find single scanned images.
The main advantages of the Portal are:
• it provides access to scanned images of manifest documents (CT Data does not); and
• images can be downloaded one or multiple at a time.

WHAT MANIFESTS ARE INCLUDED IN DEEP’S MANIFEST PERMANENT RECORDS ARE ALSO AVAILABLE VIA THE DEEP DOCUMENT SEARCH PORTAL AND CT OPEN DATA?
All hazardous waste manifest records received and maintained by the DEEP Manifest Program; including:
• manifests originating from a Connecticut Generator or sent to a Connecticut Destination Facility including manifests accompanying an exported shipment
• manifests with RCRA hazardous waste listed on them (such manifests may also have non-RCRA hazardous waste listed)
• manifests from a Generator with a Connecticut Generator ID number (permanent or temporary number)
• manifests with sufficient quantities of RCRA hazardous waste listed for DEEP to consider the Generator to be a Small or Large Quantity Generator
• manifests with PCBs listed on them from 2016 to 6-29-2018.
• Note: manifests sent to a CT Destination Facility were indexed by the Connecticut or Out of State Generator. Searches by CT Designated Facility are not possible unless such facility is the Generator for the purposes of manifesting.

All other manifests were considered “non-hazardous” manifests and not scanned. They were discarded after 2 years in accord with DEEP records retention schedule. Non-hazardous manifests include:
• Manifests with only non-RCRA hazardous waste listed
• Manifests from generators that did not have a permanent or temporary Generator ID number
• Sometimes non-hazardous manifests were considered “Hazar

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 .

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.
