The U.S. Environmental Protection Agency is accepting public comments for its proposed plan to clean up environmental pollution at parts of the Rolls-Royce turbine manufacturing plant in Indianapolis.
The plan seeks to remove tetrachloroethylene, also known as perchloroethylene or PCE, found in soil and groundwater at Rolls-Royce Plant 5 and Plant 8 and install monitoring systems.
The plan includes the operation of six air sparging and soil vapor extraction remediation systems that will clean up soil above the water table and deeper groundwater and wet soil.
If approved, the plan will also place new institutional controls at the facility, including prohibiting the use of groundwater for drinking, preventing excavation or extraction of contaminated soil or groundwater without proper waste handling procedures and requiring vapor intrusion be addressed in affected on-site building and new construction.
The proposal would require Rolls-Royce to maintain existing deed restriction on the property to ensure the land is used only for industrial and commercial purposes.
Public comments can be submitted online, through email, confidential voicemail at (312) 886-6595 or by mail to Ruth Muhtsun, U.S. EPA Region 5, External Communications Office, 77 W. Jackson Blvd., LR-16J, Chicago, IL 60604.
