Connecticut Department of Energy & Environmental Protection

DEEP headquarters at 79 Elm Street in Hartford is currently closed due to recent water damage impacting multiple areas of the building. We are working to remediate the situation and get the building back open to staff and the public as soon as possible. While the building is closed, Staff continue to work either remotely or in alternate locations. We continue to be able to receive documents via U.S. Mail or courier service, and our electronic file submittal protocols remain unchanged. For updates, please click here
