These test methods cover laboratory compaction methods used to determine the relationship between molding water content and dry unit weight of soils (compaction curve) compacted in a 4 or 6-in. (101.6 or 152.4-mm) diameter mold with a 5.50-lbf (24.5-N) rammer dropped from a height of 12.0 in. (305 mm) producing a compactive effort of 12 400 ft-lbf/ ft3 (600 kN-m/m3).

This statewide coverage consists of several major soils and some minor soils groups.

Phase II hydrogeologic investigations were conducted at the Far West Site to characterize principal hydrogeologic units and structural features, hydraulic properties of units in the unsaturated and saturated zones, and the occurrence, movement, and chemical quality of groundwater. Hydrogeologic investigations were conducted in conjunction with geotechnical investigations by Klohn Crippen Berger (KCB) in support of the Resolution Copper Mining LLC (RCM) tailings prefeasibility assessment for the Far West Site.

The purpose of this report is to summarize current knowledge of population and habitat trends for species identified as management indicator species (MIS) for the Tonto National Forest.

Major aquifers, well yields, estimated natural recharge, number of index wells and date of last water-level sweep are shown in Table 8.1-6. Figure 8.1-6 shows aquifer flow direction and water-level change between 1991-1992 and 2002- 2003 for the entire Phoenix AMA.

The Rangeland Administration System (RAS) provides grazing administrative support and management reports for the BLM and the public. The Rangeland Administration system serves as an electronic calendar for issuance of approximately 18,000 applications and 2,400 grazing authorizations (Permits, Leases, and Exchange-of-Use Agreements) per year, eliminating the need for manually processing these forms.

Phase I Environmental Site Assessment (ESA) for an approximately 60.4-hectare (149.3-acre) site in Maricopa County, Arizona (6L Ranch).
