"The Minnesota Court of Appeals on Monday ordered state regulators to reconsider a wastewater permit that was granted to PolyMet Mining Corp (POM.TO) to build an open-pit copper mine, though judges rejected six other challenges to the permit from environmentalists.

The appeals court ordered the Minnesota Pollution Control Agency to reconsider whether any groundwater runoff from the proposed mine would pollute navigable waterways.

The decision does not cancel the permit but it does further delay the timeline for when construction could begin on the $1 billion project at a time when the United States is trying to boost production of copper and other metals needed for electric vehicles."
