“The Hydrometallurgical Residue Facility is a concern for fisheries”

This comment from a DNR Area Fisheries Supervisor was filed on the PolyMet draft dam permits and pertains to the “hydrometallurgical residue facility,” which is where the most toxic waste from the PolyMet processing plant would be permanently stored. As it notes, this would be a lined facility that is supposed to be capped after closure. As noted “even if it takes 200 years, the waste will still be there and in its location would be very susceptible to leaching into nearby wetlands and groundwater.” TFA comments_ RFC 2016_1383 and 1380
