AERMOD Modeling Protocol to Assess Ambient Air Quality Impacts

Document ID: aermod-modeling-protocol-20111212

The air impact analysis presented herein is based on the modeling protocol titled "Modeling Protocol to Assess Ambient Air Quality Impacts from the Rosemont Copper Project" which is being submitted along with this report. This protocol was developed following applicable portions of the Arizona Department of Environmental Quality (ADEQ) guidance document: Air Dispersion Modeling Guidelines for Air Quality Permits, December 2004 (ADEQ Guidance), the EPA Guideline on Air Quality Models (Guidelines, 40 CFR Part 51, Appendix W, November 2005) and recommendations from the Federal Land Managers. The remaining sections of this report present the air dispersion modeling methodology and modeling results for the Rosemont Project.
