MnDOT Best Management Practices for Potentially Acid-Generating Rock

The purpose of this project is to develop a guidance manual specific to Minnesota and its geological formations so that potentially acid-generating (PAG) rock can be properly identified and characterized prior to construction, properly handled and mitigated during construction, and properly monitored (if needed) following construction. Recent project experience by MnDOT and Minnesota Department of Natural Resources will be incorporated into the manual (for example, TH169 Eagles Nest and Vermillion State Park) as well as methods and best management practices found in other states' guidance manuals (PennDOT and TennDOT, in particular).
