IMPACTS OF COPPER-NICKEL MINING AND

Placing a copper-nickel mine and associated operations in a watershed would cause changes in the quality, quantity, and timing of water flowing out of that watershed. This report describes the possible impacts on the hydrology of the Copper-Nickel Study Area (Study Area) by copper-nickel mining, milling, smelting, and refining.
