Connecticut Transfer Act: Forms, Sunset, and Penalties

The Connecticut Transfer Act was the state law that governed the sale and transfer of commercial and industrial properties with a history of hazardous waste activity, requiring environmental investigation and cleanup as a condition of the transaction. The program sunset on March 1, 2026 under Public Act 25-6, so form filings are no longer required for transfers after that date. Cleanup obligations that attached to transfers completed before the sunset remain fully enforceable, and open Form III and Form IV commitments must either be finished under the old framework or moved into Connecticut’s new Release-Based Cleanup system.

What Made a Property an “Establishment”

The Act reached only properties that met the statutory definition of an “establishment” under Connecticut General Statutes 22a-134(3). The test was activity-based. What mattered was what happened on the site, not what type of building sits there now.

A property qualified if any of the following occurred there:

More than 100 kilograms of hazardous waste was generated in any single month on or after November 19, 1980.
Hazardous waste generated elsewhere was stored, recycled, treated, transported, or disposed of at the property.
Dry cleaning operations were conducted on or after May 1, 1967.
Furniture stripping was conducted on or after May 1, 1967.
A vehicle body repair facility operated on or after May 1, 1967.

The net was wide. A strip mall where a dry cleaner operated decades ago qualified as readily as a factory that generated barrels of industrial solvent. When a site qualified, the entire parcel was pulled in, not just the corner where the activity took place. The one narrowing rule applied to multi-tenant properties: only the areas used by the qualifying business fell within the establishment boundary.¹

Several situations were carved out. A one-time spike above the 100-kilogram threshold didn’t count if it was the first generation event or the first since the last form filing. Hazardous waste generated solely from cleaning up existing contamination, removing building materials like asbestos, clearing out unused chemicals during a building cleanout, or completely shutting down a business (provided waste was removed within 90 days) also did not trigger establishment status.¹

Transactions That Triggered the Act

For any qualifying establishment transferred before the March 2026 sunset, the Act was activated by a “change in ownership.” That covered straightforward property sales, transfers of more than 50 percent of the stock or membership interests in the owning entity, and corporate mergers that brought new ownership to the establishment.¹

Long leases could also trigger the Act, but only those running 99 years or more, counting any options to extend. A 98-year lease was exempt. A 99-year lease was not.¹

Who caused the contamination did not matter. A buyer purchasing a site polluted by a long-gone tenant still inherited Transfer Act obligations if the property was an establishment.

The statute also listed transactions that did not count as a “transfer of establishment” even when the property clearly qualified. Foreclosures, tax lien foreclosures, tax warrant sales, deeds in lieu given to a municipality, and eminent domain takings were all exempt. A lender who took a deed in lieu was outside the Act if it qualified for the secured lender exemption under CGS 22a-452f. Transfers between close family members (siblings, spouses, children, parents, grandparents, nieces, nephews, aunts, and uncles), transfers approved by Probate Court, and devolution of title to a surviving joint tenant or to a fiduciary under a will or intestate succession were also excluded. So were corporate reorganizations that did not substantially affect ownership of the establishment, issuances of new stock or securities, and transfers of 50 percent or less of ownership interests. A bankruptcy court-ordered transfer to a nonprofit organization was likewise excluded.¹

The Four Forms

Before the sunset, the transferor of an establishment had to give the transferee a form before closing and send a copy to the DEEP Commissioner within ten days after the transfer. The form depended on the environmental condition of the property.²

Form I was used when investigation showed no release of hazardous waste or hazardous substances had occurred, or when any release of a hazardous substance had been remediated and verified by a Licensed Environmental Professional.
Form II was used when a release had occurred but the Commissioner had approved in writing, or an LEP had verified, that all contamination had been cleaned up to applicable standards.
Form III was used when environmental conditions were unknown, or a release had occurred and cleanup was not yet complete. The certifying party who signed the Form III agreed to investigate the entire parcel and remediate any contamination to regulatory standards.
Form IV was used when investigation was complete, a release had occurred, and an LEP verified that all remediation was done except for natural attenuation monitoring, post-remediation groundwater monitoring, or the recording of an Environmental Use Restriction. The certifying party agreed to finish that remaining monitoring.

If the transferor could not file a Form I or Form II because the site was uninvestigated or still contaminated, the fallback was a Form III or Form IV. Nobody else at the table could sign one of those forms unless they voluntarily stepped forward as the certifying party. If nobody did, the obligation fell on the transferor by default.²

Certifying Party Obligations

Signing a Form III was the most consequential commitment in the framework. The certifying party took on a legally binding duty to investigate and clean up the entire parcel, no matter who caused the contamination. These commitments remain enforceable for any form filed before the sunset.

Within 75 days of DEEP confirming the Form III was complete, the certifying party had to submit a schedule for investigation and remediation. The statute set default deadlines: investigation completed within two years, remediation started within three years, and final or interim verification due on a timeline set by the Commissioner. DEEP could extend these deadlines in writing, but only if the certifying party requested the extension before the deadline lapsed.²

Unless DEEP elected to take direct oversight, the certifying party had to use a Licensed Environmental Professional to verify that the investigation followed prevailing standards and that any remediation met the applicable cleanup criteria. An LEP’s verification could close out a site the same way Commissioner approval would.²

What the March 2026 Sunset Changed

Public Act 25-6 rewrote the definition of “transfer of establishment” to cover only transactions occurring on or before March 1, 2026. Property transfers after that date do not require Forms I through IV. The Property Transfer Program no longer functions as a gate on real estate transactions.³

Existing obligations survive. A Form III or Form IV filed before the sunset remains a binding commitment. As of March 1, 2026, the cleanup standards for all sites, including those still working through the old program, became the Release-Based Cleanup Standards.³

Public Act 25-54 created a bridge for certifying parties with open obligations. A certifying party whose site has already been investigated in accordance with prevailing standards submits a Release Catalogue Report prepared by an LEP, cataloging each individual release found on the property. Ninety days after submission, or after acceptance if DEEP audits the report, the certifying party can start addressing each catalogued release under the Release-Based process. Once every release has a closure report that has been accepted or cleared the audit period, DEEP issues a letter confirming there are no further Transfer Act obligations for that parcel.³

Certifying parties can also stay in the Transfer Act framework and finish their Form III or Form IV verification on the original deadlines. Either way, if a new release is discovered on a Transfer Act site and isn’t statutorily exempt, it must be reported to DEEP under the Release-Based Cleanup Regulations regardless of whether the rest of the site remains in the old program.⁴

Penalties for Walking Away From an Open Obligation

DEEP keeps its enforcement authority over Transfer Act obligations triggered before the sunset. Certifying parties who abandon remediation, miss filing deadlines, or submit false information face administrative and civil consequences.

Under Connecticut’s general environmental enforcement framework, DEEP can impose administrative civil penalties of up to $25,000 per day for each violation. The Commissioner weighs the degree of harm to public health and the environment, the severity of interference with natural resources, and the impact on surrounding property. DEEP can also order violators to conduct additional site assessments and remediation at their own expense.⁵

A certifying party who abandons a Form III or Form IV also faces civil lawsuits from subsequent owners, neighbors, or others harmed by the unaddressed contamination, and potentially federal CERCLA exposure if EPA concludes the state-supervised cleanup has stalled.

Federal CERCLA Overlap

Complying with the Connecticut Transfer Act does not automatically shield a property owner from federal liability under CERCLA. The two systems interact, but they are not the same.

CERCLA Section 128(b) limits EPA’s ability to bring enforcement actions at “eligible response sites” where a party is conducting or has completed cleanup in compliance with a qualifying state response program. Connecticut’s program qualifies, so a party actively remediating under DEEP oversight generally will not face parallel federal enforcement for the same contamination. Exceptions apply: EPA can still act if contamination crosses state lines, if the site poses an imminent and substantial danger, or if new information reveals threats that were not known when the state-supervised cleanup was approved.⁶

Buyers should also know about the federal Bona Fide Prospective Purchaser defense. Under 42 U.S.C. § 9601(40), a buyer who acquires property after contamination occurred can avoid CERCLA liability if they conducted appropriate pre-purchase inquiries, are not affiliated with any party responsible for the contamination, provide all legally required notices about discovered hazardous substances, and take reasonable steps after purchase to stop ongoing releases, prevent future ones, and limit human exposure. Failing to meet the post-purchase obligations destroys the defense entirely, even for a buyer who did thorough due diligence before closing.⁷
