Voluntary Remediation Programs

The Department of Energy and Environmental Protection (DEEP) lists voluntary cleanup under its Voluntary Remediation Programs page, last modified April 13, 2026. The page describes three things: a program under Connecticut General Statutes section 22a-133x, a Voluntary Parcel-Wide Cleanup Program that it says Public Act 25-6 put in place of the section 22a-133y program on March 1, 2026, and a legacy Voluntary Remedial Program under section 22a-133y that ran from June 29, 1995 to March 1, 2026, which it also calls the VRP.

In a Phase I ESA

These are the Connecticut forms of the state voluntary cleanup records that ASTM E1527-21 lists as a standard source. The general reading of a voluntary cleanup listing is on the VCP page. Three Connecticut details shape how to read one, and each depends on a date.

• The legacy program ended March 1, 2026. DEEP says that to enter it, a property had to be in an area where groundwater is classified GB or GC and not subject to an administrative order, consent order or stipulated judgment about the contamination. A Remedial Action Plan prepared by a Licensed Environmental Professional (LEP) was due on entry. The page says a Verification Form and Final Remedial Action Report signed and sealed by the LEP had to be uploaded into REACT before March 1, 2026 for remediation to have been completed under it, and that the owner must keep records of the remedial action for at least ten years.
• The section 22a-133x program and brownfield relief. DEEP says that after March 1, 2026 it will primarily be entered as a requirement for enrollment into the Abandoned Brownfield Cleanup Program, with a $3,250 fee. See Brownfield Liability Relief Programs.
• The parcel-wide program is elective and has conditions. DEEP says it is for owners to clean up and verify all releases on a parcel, if a Phase II Investigation is started before a release is discovered or within 60 days of discovering one, if the parcel is not subject to the Property Transfer Program or to an order or stipulated judgment to clean up a release, and if an LEP gives notice to enter the program by the earliest reporting deadline. It says an Environmental Condition Assessment Form must be uploaded into REACT, that there is no entry fee but tiering fees will apply two years after entering the program, and that the site enters a tier two years after the Phase II Investigation begins unless the parcel is verified first.

DEEP also says that after the Release-Based Cleanup Regulations took effect, sampling at sites already in the section 22a-133x program starts the schedule for reporting releases under them, either immediately, within 120 days or within one year depending on the level of contamination present. See the Release-Based Cleanup Program page.

Where to look a site up

• DEEP's Release, Environmental Assessment, and Cleanup Tracker is where it says the verification and report documents are uploaded. See the REACT page.
• DEEP's Contaminated or Potentially Contaminated Sites list says Voluntary Remediation Programs sites are among its sources.
• The pages read do not publish a separate list of voluntary remediation sites.

Getting the file

Verification forms and reports are uploaded to REACT. Older documents are in the DEEP Online Document Search Portal. The overview sets out the two cut-off dates DEEP's pages give.
