Federal officials say they're preparing a final cleanup for the Radford Army Ammunition Plant's annex in Dublin.
The 3,000-acre facility is the former New River Ordnance Works, site of a World War II powder-bagging operation for artillery, cannon and mortar projectiles.
After a 13-year investigation of the site, Army officials say they now have a $2.4 million cleanup plan for the facility, which closed in 1945.
Investigators disclosed last month that safety flooring in some areas released lead, copper and asbestos into nearby soil as it degraded over time. Chemical residues also have been found in a 600-foot ravine once used to dump building debris and in a pit once used to burn unwanted explosives.
