Brownfields in Connecticut

What is a brownfield?

Connecticut defines a brownfield 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. These unknown environmental liabilities often prevent communities, developers and investors from restoring these properties to productive use and revitalizing impacted neighborhoods.

The Connecticut Brownfields Program encourages the cleanup and redevelopment of contaminated properties by providing resources to address the concerns associated with brownfield sites including technical assistance, liability relief programs and, in some cases, funding.

Brownfield Grant Round 3 is now open:  DEEP’s CERCLA 128(a) Brownfield Grant is funded through the EPA’s supplemental CERCLA grant to administer to brownfield sites for the purpose of conducting environmental assessment and cleanup activities. The focus of the grant is on projects that will enable the creation, preservation, or addition of park space, greenways, or other publicly accessible recreational space. 
Closing date Friday, December 5th at noon.
