A Guide to DEEP’s Environmental Quality Records Center (File Room) 

Starting June 1st, public access to DEEP’s records center at 79 Elm Street, Hartford will be available to a maximum capacity of 12. We strongly recommend you schedule an appointment online ahead of time to confirm your spot on any given day. 

Documents and Data Available Online

Documents

Use the DEEP Document Online Search Portal to search, view images and download currently available agency documents, including Hazardous Waste Manifests, Spill Reports and limited numbers of other documents.

Data

Many datasets concerning the environment and natural resources category can be found within the CT Open Data platform, which include the datasets listed below. These datasets can be searched, sorted, tabulated, and downloaded.  The datasets only provide data from DEEP databases.  They do not provide access to documents (images) like the DEEP Document Online Search Portal.  However, the datasets can be very useful search tools, especially since some of the datasets do not yet have corresponding documents (images) available via the DEEP Document Online Search Portal.

Datasets on CT Open Data:

Spills Incident Tracking System (SITS) Dataset (This dataset includes the SITS Database for 1996 through the present)—updated about every 2 weeks. (Documents available via the DEEP Document Online Search Portal.)

Hazardous Waste Manifest Portal Metadata (all years of manifests, 1981 – 2018)

Note: This dataset contains only the data from the Portal that is associated with the scanned manifest documents (i.e. Town, Address, Company Name, etc.).  Scanning of all years of manifest documents is complete, and the images are available via the DEEP Document Online Search Portal.  Searching the Open Data Metadata dataset is faster and more powerful compared to the Portal. The Metadata dataset includes a description of the dataset and the manifest documents.

Hazardous Waste Manifests 1984-2008 (older, incomplete Manifest dataset)

Note: This dataset is available in case the public wants to compare search results between the newer, complete Portal Metadata and the older, 1984 – 2008 dataset.  There are small differences between the two datasets that may result in different search results.

Registered Underground Storage Tanks (UST)

Leaking Underground Storage Tanks  (LUST) (some documents are available via the DEEP Online Search Portal)

Toxics Release Inventory (TRI) Facility List by Year

Environmental Monitoring Results for Radioactivity: Air Samples
