Keystone Sanitary Landfill now has four more months to compile about 38 additional years of engineering details about its controversial expansion plan.
The state Department of Environmental Protection on Friday granted the Dunmore and Throop operation’s request for more time to respond to the agency’s first environmental review — just as the three-month deadline approached Tuesday.
Keystone first submitted its expansion plan to DEP on March 20, 2014, to begin a lengthy review process on increasing the landfill’s permitted disposal area from 335 acres to 435 acres and pile waste up to 165 feet higher than currently allowed.
