The U.S. Environmental Protection Agency announce it approved the expansion of a cleanup at an inactive power plant abutting the Indiana Dunes National Park.
The EPA issued the final cleanup plan for Area C of the Northern Indiana Public Service Co.’s Bailly Generating Station in Chesterton.
NIPSCO used the area known as Solid Waste Management Unit 15 as a coal ash dump during the 1960s and 1970s. The area now threatens wildlife in the Dunes with boron contamination.
Initially, the cleanup plan included the excavation of 92,000 cubic yards of coal ash at SWMU 15. The expanded plan also includes the removal of coal ash at the smaller SWMU 14 and other portions of the site.
The proposal includes plans to mix coal ash found below groundwater level with a cement mix to prevent the contamination from spreading. Other coal ash will be excavated and taken to a lined landfill on the grounds of the Schahfer Generating Station in Wheatfield.
