Freedom of Information Act (FOIA) Requests

The Connecticut Freedom of Information Act gives you the right to obtain records and attend meetings of all public agencies with certain exceptions.

Are there files that I should review before submitting a FOIA request?
Yes. You can review agency documents in the DEEP Records Center (file room), the DEEP Document Online Search Portal, and the Connecticut Open Data Portal.

Many datasets concerning the environment and natural resources category can be found within the CT Open Data portal, 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 a corresponding documents (images) available via the DEEP Document Online Search Portal.

Datasets on CT Open Data:

Spills Incident Tracking System  (SITS Database for 1996 through the present)—updated about every 2 weeks

Note: This dataset contains all of the data from the SITS database.  Scanning of corresponding Spills documents is progressing alphabetically by town, with scanned images available via the Portal. Scanning is estimated to be completed by the end of December 2020, and has currently been completed through towns in the middle of the alphabet.

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 Portal.  Searching the 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)

Environmental Monitoring Results for Radioactivity: Air Samples

How long does it take to process a FOIA request?
DEEP receives many requests on a daily basis.  For each request we must search our files to locate the requested records and determine which, if any, contain privileged information. Your search will be conducted as promptly as possible, but may take 10-12 weeks or longer. Once completed, you will be notified of the number of documents that have been compiled.

Are there any fees related to the FOIA request?
Copying fees are assessed at $ 0.25 per page.  If certified copies are requested the fee is $1.00 for the first page and $0.50 for subsequent pages. Documents that currently exist in electronic format will be provided at no cost. Please be advised that if your total cost exceeds $10.00, you will need to pre-pay before documents will be released to you.

I am researching several properties.  Can I submit one FOIA request for all of them?
No.  Each request can identify only one specific property location.  You will need to submit separate requests for each additional property.  Note: Please be as specific as possible regarding the type of information you are requesting.

In what format will the requested documents be provided?
Requested documents will only be provided in the format in which they presently exist within the DEEP records.  

I have already submitted a FOIA request, should I search other resources such as the Records Center (public file room)?
If you decide that your needs may be more quickly addressed if you review the files yourself, please notify the FOIA Administrator of your intention to review file room documents so they may note the same on your submitted request.  We cannot guarantee that all of the requested  documents are currently available within our public file room.

If after your review you still wish to proceed with your originally submitted FOIA request, please notify the FOIA Administrator so they can ensure that your request is put back into the schedule for processing. 

Can I find out the status of my FOIA request?
You may contact the FOIA Administrator to request information regarding the status of your FOIA request.

How do I make a FOIA Request?
Freedom of Information Requests for documents from the Department of Energy and Environmental Protection (other than for Public Utilities Regulatory Authority (PURA) documents) under the Connecticut Freedom of Information Act should be made using the DEEP FOIA Request form.  You may submit your completed form via email to, fax to (860) 424-4053 or send by regular mail to:
