A sign near an artificial pond marks the end of public access in the area proposed for Rosemont Copper's open-pit mine in the Coronado National Forrest in the Santa Rita Mountains southeast of Tucson.
More copper produced - yet less water sucked from the aquifer, less pollution, less juice needed to power the mine and mill, and fewer trucks on the road.
The newest U.S. Forest Service statement on the proposed Rosemont Mine leaves key questions unanswered about the project's timetable.
The proposed SunZia Southwest Transmission Project would use lattice steel towers similar in height to these near Spearville, Kan., at nearly 130 feet tall and 90 feet wide, to support the 500Kv lines across Southern Arizona and New Mexico. They would be spaced approximately 1,400 feet apart.
A proposed power-line system to deliver renewable energy across the Southwest could disturb habitat for sensitive species, harm more than 300 cultural sites, damage scenic views and increase fire risk while it's being built, a new federal environmental report says.
