Carlisle Oversight Committee Prepares Questions for April EPA Community Meeting on 2229 Main Street

CARLISLE — March 20, 2026 — Carlisle's 2229 Main Street Oversight Committee voted to accept its March 6 minutes and organized its response to two upcoming EPA events at its March 20 session. The committee discussed two pre-release technical documents from remediation contractor De Maximis — a draft Remedial Action Report dated February 18 covering uranium and overburden in the holding basin area, with public comments due May 1, and a 100 percent Remedial Design amendment covering site-wide soils and sediments dated March 13, with comments due April 24. Chair Ray asked members to submit questions within days so they can be compiled and forwarded to EPA liaison Kara before a technical preview session at the 2229 site, ahead of a public community meeting EPA and De Maximis will hold on April 2. Topics flagged for the EPA to address publicly include whether the site qualifies as a brownfield ("this is not going to be a brownfield site," per committee discussion), the depth of soil removal, the overall remediation timeline now projected to 2031, and the status of the town's interest in acquiring the property — a negotiation member Pam confirmed is active but unresolved, with no purchase expected before the holding basin remediation is substantially complete.
