Poly Met Mining has submitted applications for various permits required to construct and operate its NorthMet project in north-eastern Minnesota, US.
The applications submitted for the copper-nickel-precious metals project are permits for water quality, water use and dam safety.
PolyMet president and CEO Jon Cherry said: “Formal submission of water-related permit applications is another important milestone for PolyMet and the NorthMet Project.
“We recognise that water is one of Minnesota’s most valuable resources and we have taken extra time and effort to ensure that our permit applications detail the ways in which we will protect this resource and meet the various regulatory standards required for Minnesota’s first copper-nickel mine.”
The company also expects to submit air-related and permit to mine applications soon.
Cherry further added: “We have been deliberate in preparing our formal permit applications to ensure they are complete and align with the Final Environmental Impact Statement so that the agencies can process their reviews as efficiently and rigorously as possible.”
The National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) permit, also called water quality permit, will establish the terms and conditions such as monitoring. These must be met to help prevent the facility discharging into surface or groundwater of the state.
Water use permit enables to withdraw or use water from a surface or groundwater source for the NorthMet project.
The dam safety permits establish the design, construction, and operating parameters in order to ensure safe operations of facilities with water impoundments.
