EnSafe Inc.'s award-winning, fast-track remediation of a contaminated site in
Charleston, S.C., will be in the spotlight again this month when it is
recognized by U.S. Environmental Protection Agency top officials as the 1,000th
"Construction Complete" Superfund site in the U.S.
USEPA Administrator Stephen L. Johnson is scheduled to be onsite Nov. 20, along
with Susan Bodine, assistant USEPA administrator for Superfund, and Jimmy
Palmer Jr., USEPA Region 4 Administrator. Johnson is expected to recognize the
accomplishments of the Superfund Program over the last 26 years, and discuss
the economic re-vitalization and benefits afforded by the Macalloy cleanup and
associated redevelopment activity at the site, which was impacted by the highly
toxic hexavalent chromium.
 This EnSafe
remediation project received statewide recognition early in 2006 in winning the
top environmental category award in the American Council of Engineering
Companies of Tennessee's Engineering Excellence award.
EnSafe not only shortened the time frame for readying an environmentally
impacted site in an economically depressed community for beneficial reuse but
also developed an innovative engineering design that fast-tracked the
remediation of more than 170,000 tons of contaminated fill material and 2.75+
million gallons of groundwater.
EnSafe worked closely with Macalloy Corp. to take a 147-acre, Cold War-legacy
site from its inclusion on the National Priorities List to remediation in less
than six years , about half the typical duration of the Superfund process.
Getting the property ready for beneficial reuse as quickly as possible was
important for both Macalloy and the community, which lost 6,272 jobs when its
largest employer closed in 1996. The Macalloy plant closed in 1998, taking the
city's second-largest taxpayer off the tax rolls and costing the Charleston
area another 200 jobs.
Memphis-based EnSafe engineers fast-tracked the project and developed an
innovative remedy that treated site fill via onsite chemical reduction using
mechanical mixing; groundwater was treated using in situ chemical injection to
create a permeable reactive barrier. EnSafe's innovative design was crucial in
remediating the site quickly, going from Superfund listing in October 1999 to
redevelopment in early 2006.
EnSafe is a Memphis-based global professional services company focusing on
engineering, environment, health & safety, and technology with 19 locations
worldwide.
EnSafe also received recognition from the U.S. Navy in October for a project in
which it developed precedent-setting remediation technologies. EnSafe's
remediation efforts resulted in Naval Weapons Industrial Reserve Plant
McGregor, Texas, becoming the first Navy property in the nation to receive
USEPA's "Ready for Reuse" determination.
EnSafe developed precedent-setting remedial technologies for a supposedly
untreatable contaminant , perchlorate , that was threatening the public
drinking water supply at a former Navy weapons manufacturing plant. The
remediation project won national and state recognition: the Grand Award in the
American Council of Engineering Companies of Tennessee's 2000 Engineering
Excellence Competition and two Navy awards in 2000 , the Chief of Naval
Operations Award for Environmental Restoration and the Secretary of the Navy
Award for Environmental Restoration. |
