Final Environmental Impact Statement (FEIS)NorthMet Mining Project and Land ExchangeNon-Variant Form LettersAlphabetical by sender's first nameForm Letter 1: Mining Truth: Comments on SDEIS.Ms Lisa Fay, Department of Natural Resources To Ms Fay, Department of Natural Resources, I am writing regarding the PolyMetNorthMet supplemental draft environmental impact statement. In my view, the SDEIS is inadequate and the proposed mine plan wouldhave unacceptable environmental impacts. PolyMet Mining Company's proposed NorthMet sulfide mine fails to meet four fundamental,common sense clean water principles, principles the mining industry previously agreed to. The proposed mine plan does not keepMinnesota's water safe and clean The best case scenario for the mine anticipates at least 500 years of polluted water that will have to beactively treated. And, not all of the polluted water will be captured and sent for treatment. Every year, 11 million gallons of pollutedseepage from the tailings basin will enter groundwater and the environment without being treated. Every year, over 5 million gallons ofpolluted seepage from the mine site will enter groundwater and the environment without being treated. In addition, the model used topredict impacts to water quality has many flaws that may significantly under-represent pollution risks. Indeed, the model has been shownto be inaccurate in representing current conditions for water quality surrounding the mine site undermining confidence that it canaccurately predict future water conditions. The proposed mine plan does not put safeguards in place for when things go wrong There areno contingency plans outlined for expected accidents that occur at all mines of this type, mishaps such as pipeline spills, accidentalreleases, failures of water collection and treatment systems, tailings basin spills. These are foreseeable events that should have emergencyplans developed and articulated so the public has confidence in the company's ability to respond to a crisis. During operations, over 6-2million gallons of polluted water a day will need to be treated. The mine plan does not describe what will happen if the water treatmentplants break down. Will this pollution be discharged into the environment. The mine would contain a complex network of miles ofpipelines, carrying polluted and treated water to and from various locations. The mine plan does not describe what would happen if abreak were to happen in a pipeline carrying high concentrations of toxic metals and sulfates. The proposed mine plan does not leave thesite clean and maintenance free The plan for at least 500 years of active water treatment violates Minnesota Rules (6132-3200) that callfor the mine to be left maintenance free at closure. 526 acres and over 167 million tons of reactive waste rock would be left on the surfaceafter closure. Surrounding this would be a system to collect contaminated seepage that must be monitored and maintained for hundreds ofyears or longer. A synthetic and soil cover placed over the waste rock pile would require annual maintenance, repairing of erosion, andremoval of plants that might perforate the synthetic material. A pit "lake" would be left whose water levels would need to be maintainedthrough pumping to prevent contaminated overspills into the nearby Partridge River. A tailings basin pond would need to have its waterlevels maintained through pumping to prevent contaminated water from over-topping the dams and entering the nearby Embarrass River.A lengthy network of pipelines conveying polluted and treated water would need to be monitored and maintained for at least hundreds ofyears. The proposed mine plan does not protect Minnesota taxpayers The plan commits Minnesota to at least 500 years of polluted watertreatment without providing critical information about how this will be paid for and who will be responsible for it. Details about financialassurance a "damage deposit" the company provides are not outlined in the revised mine plan. The public does not know how much 500years of water treatment will cost, how the company will be held responsible for centuries of costly water treatment, or how the publicwill be protected from liability. Thank you for the opportunity to provide input on the PolyMet SDEIS. Due to the problems with thedraft mine plan outlined above, I believe the mine should not be built as described.
