PRM has received a set of documents from the Minnesota Pollution Control Agency (PCA) that details both ongoing and proposed mining projects in northern Minnesota. The documents describe modifications to existing waste water treatment facilities at the Peter Mitchell taconite mine, as well as aspects of the proposed NorthMet copper-sulfide mine.
PRM will post documents for public review as soon as possible, along with newly obtained records from the Environmental Protection Agency, the Minnesota DNR, and the U.S. Army Corps of Engineers. PRM has already started to post records obtained from EPA. Find them here.
