Review deadline changed for Arizona mining project by The Associated Press Last Updated Dec 15, 2020 at 12:12 pm EDT PHOENIX — The U.S. Forest Service has moved the deadline up to complete its review of the Resolution Copper mine east of Phoenix to the end of the year, accelerating the project before President Donald Trump leaves office. The Tonto National Forest, where the mine would be located, must now submit a final environmental impact statement by Dec. 31, The Arizona Republic reported. The final document was previously expected in 2021 or 2022. A final review document sets the clock ticking for the land swap and the Forest Service has said the exchange will be finalized no more than 60 days after the release of the final statement.
