The Department of Defense, specifically the U.S. Army Corps of Engineers Louisville District, intends to award a sole source contract modification to Jacobs, Inc. for Remedial Investigation work at the Defense Supply Center Columbus (DSCC) in Ohio. This procurement is aimed at completing environmental sampling at four additional sites as part of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process, following a request from the Ohio Environmental Protection Agency. The opportunity is significant for ensuring compliance with environmental regulations and addressing contamination issues at the site. Interested parties may submit capability statements or proposals for consideration, but must do so within 14 days of the notice, and should direct inquiries to Kari Rogers at kari.a.rogers@usace.army.mil.
