MnDOT BMP's for Potentially Acid-Generating (PAG) Rock

Status:  Active
Project Start Date:  02/21/2018


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 MnDNR will be incorporated into the manual (TH169 Eagles Nest and Vermillion State Park, for example) as well as methods and BMP's found in other states' guidance manuals (PennDOT and TennDOT, in particular).
