With the 2021 adoption of the amendments to the RSRs and the EURs, Connecticut stands poised to accelerate the pace of the cleanup of pollution that threatens human health and the quality of our environment. The adoption of these regulations provides much needed flexibility and cost savings for property owners engaged in the remediation of polluted soil and groundwater while maintaining or increasing the degree of protectiveness of cleanup efforts in Connecticut. In general, all applications for an ELUR or Notice of An Activity and Use Limitation, and all verifications submitted after February 16, 2021 will be subject to the newly revised regulations.
