For the second time in two days, a former Minnesota Pollution Control Agency (MPCA) official defended her decision to delete e-mails related to concerns over the agency's handling of PolyMet Mining Corp.'s water-quality permit.
The complicated permit, running hundreds of pages, was a major triumph for Toronto-based PolyMet when the MPCA finally issued it in December 2018. The permit has since been suspended, and construction of the copper-nickel mine in northeastern Minnesota has been delayed amid accusations that the MPCA and U.S. Environmental Protection Agency conspired to hide the EPA's serious criticisms of the permit, meant to control pollution from the controversial mine.
On Friday, on the fourth day of a trial-like hearing in St. Paul into whether the agency bent the rules as it drafted the permit, former MPCA Assistant Commissioner Shannon Lotthammer was back on the stand in Ramsey County District Court before Chief Judge John Guthmann.
John Martin, an attorney representing the MPCA, argued that neither Lotthammer nor the agency tried to suppress anything related to the permit and had sought ample public input on the draft.
He painted a picture of an agency struggling to make the required responses to the hundreds of public comments to the draft permit when it was opened to public comment last year.
As she did Thursday, Lotthammer testified that her e-mail to the EPA simply asked the agency to hold off submitting its formal written comments on the public draft of PolyMet's permit until after the public comment period closed, and to wait so that the MPCA could give the EPA a new draft that incorporated public input. The EPA would then have 45 days to respond.
The approach "just made a lot of sense to me," Lotthammer said.
She defended deleting the e-mail, saying it followed her understanding of the MPCA's rules on record retention.
