Proposed canyon uranium mine, Coconino County, Arizona

The final form of environmental impact statement (EPA No. 860405F) deals with a plan to mine uranium on unpatented mining claims in Arizona using a single 8 by 18-foot vertical shaft and a second 8-foot diameter ventilation and escape shaft. The disturbed area would be about 15 acres for shafts and buildings. Positive impacts include the benefits of increased employment and improved roads, while negative impacts would require procedures to mitigate radionuclide contamination and radon gas emissions that would be harmful to workers and plant and animal life in the area. Increased traffic flows would also cause problems. The summary lists several legal mandates for the impact study and a reference for the draft version
