MPCA Posts PolyMet Draft Water Quality Permit and Section 401 Certification

Agency releases draft permits to Tribes, EPA and PolyMet prior to public meetings

ST. PAUL, Minn.--(BUSINESS WIRE)-- The Minnesota Pollution Control Agency has informed Poly Met Mining Inc., a wholly-owned subsidiary of PolyMet Mining Corp. (together “PolyMet” or the “company”) TSX: POM; NYSE AMERICAN: PLM – that it has posted the draft water quality permit and draft Section 401 Certification and supporting permit documentation on its website for the NorthMet copper-nickel-precious metals project.

As previously announced by the MPCA, public meetings on the draft air and water permits and the draft Permit to Mine will be held jointly February 7 and 8, 2018, in Aurora and Duluth, respectively. The public comment period for MPCA’s draft permits will begin prior to the February public meetings. The draft Permit to Mine was released for public comment by the Minnesota Department of Natural Resources on January 5, 2018.

The water quality permit establishes specific limits and requirements to protect Minnesota’s surface and groundwater quality for a variety of uses, including drinking water, aquatic life and recreation. It is also known as an NPDES/SDS (National Pollutant Discharge Elimination System/State Disposal System) permit.

The 401 Certification is a proposed approval by the MPCA that the company’s plans, as submitted or with conditions written by the MPCA, will protect water quality.

“With the release of the draft Permit to Mine earlier this month and now the draft water quality permit and draft 401 Certification, we move ever closer to fulfilling our commitment to build an environmentally responsible mine and to provide the jobs, mineral diversity, and tremendous economic benefits that this project will bring to the Iron Range and the state,” said Jon Cherry, president and CEO.

The draft water quality permit and 401 Certification posted by the MPCA, including related conditions and other permit documentation, are found at https://www.pca.state.mn.us/northmet.
