US' EPA to investigate PolyMet's copper-nickel project in Minnesota

It was reported that the US Environmental Protection Agency (EPA) was investigating PolyMet Mining's US$1 billion investment in copper-nickel mines in Minnesota because of doubts that the project did not meet the requirements of the Clean Water Act. The project would become the first copper-nickel mine in the state.
Last Thursday, the EPA expressed concerns about the licenses signed by the Minnesota Pollution Control Agency (MPCA) at the end of 2018.
However, the environmental organization "WaterLegacy" said that after reviewing the EPA's comments and concerns, the agency issued a license for water pollution and air pollution to PolyMet.
This permit included clear restrictions on pollutants in the discharge water and its operational restrictions, and it also clearly stated that emissions must not violate water quality standards.
