Release-Based Regulations: What’s Next?

In a landmark move to modernize Connecticut’s environmental remediation framework, the state officially adopted release-based cleanup regulations in March, replacing the decades-old Transfer Act.

This shift, viewed as a “game changer” by state officials and business leaders alike, promises to streamline property transactions, accelerate site cleanups, and unlock economic development opportunities across the state.

While the regulations were adopted in May 2025, they do not go into effect until March 1, 2026.

This transitional period gives businesses, developers, and property owners time to prepare for the new framework.

Importantly, it also offers a strategic opportunity: those considering property transfers may choose to wait until the new system is in place, avoiding the burdensome requirements of the Transfer Act.

New Regulations

Existing sites already subject to the Transfer Act must still complete their remediation obligations under that program.

However, no new sites will enter the Transfer Act after March 1, 2026, marking a full sunset of the old system.

Key features of the new regulations include:

• Streamlined transactions: Environmental reviews are no longer mandatory before property transfers, reducing delays and costs.
• Economic boost: The new framework is projected to generate 2,100 construction jobs, $3.78 billion in GDP growth, and $115 million in state revenue over five years.
• Flexibility for owners: Investigations and cleanups can now be driven by business decisions rather than regulatory triggers tied to ownership changes.
• Redevelopment incentives: By removing barriers to property transfers, RBCRs encourage revitalization of blighted or underutilized sites.

The Connecticut Department of Energy and Environmental Protection, along with the Department of Economic and Community Development, will continue working with stakeholders to implement RBCRs.

A working group has been established to monitor the rollout and recommend improvements, ensuring the new system remains responsive and effective.

As CBIA’s Pete Myers noted, “The collaboration between the business community and government has created a program that will significantly help increase investment into our state.”
