The regulations in this subpart set forth a process for developing, adopting, and revising land and resource management plans for the National Forest System as required by the Forest and Rangeland Renewable Resources Planning Act of 1974, as amended (hereafter, RPA). These regulations prescribe how land and resource management planning is to be conducted on National Forest System lands.

Apache Leap South End Parcel. Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey.

The mining community of Superior is situated in a fault-formed basin in the central part of the area. Rugged landscape southwest of Superior is commanded by Picket Post Mountain, which is an eroded volcanic vent; the remnant of a once extensive volcanic pile.

Phase I Environmental Site Assessment (ESA) for approximately 110 acres referred to as Apache Leap South End.

This technical memorandum has been prepared to summarize results of drilling and construction at hydrologic test well DHRES-14. DHRES-14 is located east of Devils Canyon, between the Devils Canyon Fault and JI Ranch Fault. The well was installed to characterize hydrogeologic conditions and provide a monitoring location in the Tertiary Whitetail Conglomerate and Precambrian Pinal Schist. Monitoring data obtained from DHRES-14 will be incorporated into the RCM hydrologic monitoring program.

Arizona hedgehog cactus surveys conducted in conformance with the monitoring requirements of the Resolution Copper Mining Pre-feasibility Activities Plan of Operations and the Tonto National Forest's Finding of No Significant Impact.

This technical memorandum presents the results from the 20-week kinetic geochemical characterization program of cleaner and scavenger tailings for the Resolution Copper Project conducted by Golder Associates (Golder). The program was carried out to evaluate the environmental stability of the tailings and supplement the static testing program reported on in a previous document (Golder 2007).

Chemical composition and equilibrium trends in mine pit lakes were examined to provide guidance for the application of geochemical models in predicting future lake water quality at prospective open pit mines. Composition trends show that elevated solute levels generally occur only at the extremes of acidic and alkaline pH conditions.

Paleoseismological data constrain the age, location, and associated magnitude of past surface-rupturing earthquakes; these are critical parameters for developing and testing fault behavior models and characterizing seismic hazard. We present new earthquake evidence and radiocarbon analyses that refine the chronology of the six most recent earthquakes that ruptured the south-central San Andreas fault in the Carrizo Plain (California, United States) at the Bidart Fan site.
