In re Issuance of Air Emissions Permit No. 13700345-101 for PolyMet Mining, Inc.
Annotate this Case
The Supreme Court reversed the decision of the court of appeals concluding that the factual findings of the Minnesota Pollution Control Agency were "insufficient to facilitate judicial review" of a permitting decision, holding that the Agency is not required under the Clean Air Act, 42 U.S.C. 7401-7671q, and its applicable regulations to investigate allegations of "sham" permitting when a source first applies for a synthetic minor source permit.
At issue was whether the Agency was required to investigate allegations of sham permitting when consider whether to approve the air-emissions permit of PolyMet Mining, Inc. for a proposed mine. Respondents challenged the Agency's decision to issue the synthetic minor source permit, asserting that the Agency failed to conduct an adequate investigation into whether PolyMet intended to operate within the limits of the permit or whether it was instead seeking a sham permit. The court of appeals concluded that the Agency's short response to the concerns of Respondents was not the "hard look" required under the Minnesota Administrative Procedure Act, Minn. Stat. 14.69. The Supreme Court reversed, holding that the applicable federal regulations and guidance contemplate retrospective enforcement after the applicant has obtained a synthetic minor source permit and do not mandate prospective investigation.
