Minnesota PCA Posts PolyMet Draft Air Emission Permit

Draft permit is last state permit required for public meeting

ST. PAUL, Minn.--()--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 air emission permit and supporting permit documentation on its website for the NorthMet copper-nickel-precious metals project.

The draft air emission permit is the last state permit required for the upcoming public meetings in February.

The agency released the draft air emission permit to tribes and PolyMet and posted it on its website for public review. 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 with the Department of Natural Resources on February 7 and 8, 2018, in Aurora and Duluth, respectively. The public comment period for MPCA’s draft air emission and water permits will begin prior to the February public meetings. The draft Permit to Mine was released for public comment by the DNR on January 5, 2018.

The draft air emission permit describes how PolyMet will meet federal and state air quality regulations and contains conditions that are enforced by both the state and federal governments. It identifies the sources on the site that could generate air emissions, details the conditions under which the company must operate to control emissions, and sets emission limits, monitoring and reporting requirements.

“We are delighted to see the last of the major state permits we have applied for released as draft permits by the state, along with the draft Section 401 Certification,” said Jon Cherry, president and CEO. “It has been a long and difficult road, and we look forward to receiving the agencies’ final decisions on these permits.”

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