LANSING, Mich. Legislation allowing for the use of coal ash and other industrial byproducts in cement and asphalt is close to reaching Gov. Rick Snyder.
The Republican-led Senate finished approving the bills almost entirely along party lines Thursday. A bill passed a day earlier would designate coal ash and other materials as having a low potential for groundwater contamination when properly managed.
The ash is a byproduct of coal combustion that poses environmental threats in landfills but also is commonly recycled for use in roads and parking lots. The legislation would shield businesses that store byproducts with beneficial uses from legal liability if they follow rules pertaining to storage.
Republicans say coal ash can be safely encapsulated while Democrats and environmentalists say residents are at risk.
