The Scenery Management System presents a vocabulary for managing scenery and a systematic approach for determining the relative value and importance of scenery in a national forest.

The purpose of this investigation was to assess the Property and surrounding areas to identify the presence or potential presence of recognized environmental conditions (RECs) potentially resulting in environmental impacts to the Property.

This report presents the results of sitespecific probabilistic seismic hazard analyses (PSHA) and deterministic seismic hazard analyses (DSHA) of four sites for the RMC tailings storage facilities options in southern Arizona.

This report summarizes the meteorological, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the second quarter, April 1-June 30, 2013.

In 1995, the Magma Copper Company discovered a porphyry copper deposit beneath thick postmineral cover 2 km south of the historic Magma mine in Superior, Arizona. Since that time drilling has delineated a large, high-grade, hypogene copper-molybdenum deposit, now named the Resolution deposit, with an inferred resource of 1,624 million metric tons (Mt) at 1.47% Cu and 0.037% Mo.

Fish surveys were conducted in order to determine the presence of absence of the Gila chub, as well as other native fishes within portions of Devils Canyon and upper Mineral Creek, and within two stock tanks in the vicinity of the Project. The Gila chub is listed by USFWS as endangered with critical habitat under the ESA.

Surveys reported here focus specifically on potential habitat for amphibians: the lentic habitats (ponds and stock tanks) and lotic habitats (ephemeral drainages and creeks) in the Oak Flat/East Plant Area, including portions of Devils Canyon south of U.S. Route 60.
