Connecticut Brownfields Inventory
DEEP’s response programs receive funding under Section 128(a) of CERCLA. As a condition of this funding, DEEP must demonstrate that we have a process, or are taking reasonable steps to include a process, to identify the universe of brownfield sites in Connecticut. EPA’s goal is for the state to provide a reasonable estimate of the number, likely location and general characteristics of brownfield sites in Connecticut.
In Connecticut, because of our long industrial history, there are probably tens of thousands of sites which are or may be polluted. Not all of these polluted sites are brownfields. Brownfields are defined differently by different parties. The State of Connecticut defines Brownfields in Section 32-760 of the Connecticut General Statutes as:
“any abandoned or underutilized site where redevelopment, reuse or expansion has not occurred due to the presence or potential presence of pollution in the buildings, soil or groundwater that requires investigation or remediation before or in conjunction with the restoration, redevelopment, reuse and expansion of the property.”
Essentially, brownfields must be unused or underutilized because they are contaminated, or there is a general and reasonable perception that they are contaminated. Many databases capture information about contaminated sites, and DEEP’s Remediation Division maintains a List of Contaminated or Potentially Contaminated Sites in Connecticut. Many sites on this list are not brownfields.
DEEP’s list of brownfields includes information compiled from the following three sources:
- Sites which have received grants or loans for brownfields redevelopment through the Department of Economic & Community Development’s (DECD) Office of Brownfield Remediation & Redevelopment (OBRD);
- Brownfield sites at which EPA funded environmental assessments or cleanups for towns or regional development agencies using federal brownfield funding. A list of these sites is also available at EPA’s Cleanups in my Community website by filtering for brownfields sites located in Connecticut; and
- Sites that have been accepted into one of the liability relief programs administered by DECD or DEEP, including the Abandoned Brownfields Cleanup Program, the Brownfields Remediation & Revitalization Program, and the Municipal Brownfield Liability Relief Program.
