Resolution Copper Project NEPA Air Quality Impacts Analyses
This Modeling Report includes a description of the methods and datasets used in the air quality modeling analyses to estimate the Resolution Project’s air quality impacts relative to the applicable Ambient Air Quality Standards (AAQS) for criteria pollutants and to Air Quality Related Values (AQRV) in the near-field domain (Class I Superstition Wilderness Areas [SWA], White Canyon Area of Critical Environmental Concern [WC ACEC], Class II Needle’s Eye Wilderness Area [NEWA]) and in several Class I Wilderness Areas in the far-field domain (Sierra Ancha Wilderness Area [SAWA], Mazatzal Wilderness Area [MWA], Galiuro Wilderness Area [GWA], and Saguaro National Park [SNP). These analyses for the EIS are technically consistent with and in addition to the analyses prepared to demonstrate compliance with the applicable Pinal County Air Quality Control District (PCAQCD) and National Ambient Air Quality Standards (NAAQS), as required by the permit application requirements in applicable PCAQCD rules.

Programmatic Agreement Info
To comply with Section 106 of the National Historic Preservation Act, the Tonto National Forest developed a Programmatic Agreement (PA) and included it in Volume 5, Appendix O of the final EIS. The PA was created in cooperation with the Advisory Council on Historic Preservation, the State Historic Preservation Office, tribes and other consulting parties. The PA contains an agreed upon process for identifying, evaluating and addressing adverse effects to historic properties associated with this undertaking.
