ENVIRONMENTAL ASSESSMENT <br /> - Air Quality/Climate Change-What would be the effects of the alternatives on local, regional, <br /> and global air quality and global climate change? <br /> - Water Quality and Quantity-What would be the effects of the alternatives on groundwater and <br /> surface water quality and quantity in the local area, and on nearby domestic/residential water <br /> wells? <br /> - Cultural Resources-What would be the effects of the alternatives on cultural resources found <br /> within the LBA boundary and properties of significance to Indian tribes? <br /> - Noise -What would be the effects of the alternatives on noise levels at residences in the Vista <br /> de Oro Subdivision, as well as at residences along the truck haul route? <br /> - Wetlands and WOTUS-What would be the effects of the alternatives on identified wetlands <br /> and WOTUS? <br /> - Subsidence -What would be the subsidence effects of the alternatives on natural resources and <br /> land uses within the LBA and on the structural integrity of nearby residences and other structures? <br /> - Land Use -What would be the effects of the alternatives on other land uses within and adjacent <br /> to the LBA and the mine? <br /> The amount of surface disturbance proposed by GCCE and analyzed in this EA totals 20 acres. Up to 10 <br /> acres would be disturbed within the first six months of the Project during construction of the low-cover <br /> crossing.That disturbance would be reclaimed upon completion of the low-cover crossing. An additional <br /> approximate 10 acres would be disturbed for a variety of typical activities that would be expected to be <br /> needed by GCCE or required by the agencies over the life of the mine as described in Section 2.2.3 above. <br /> The location, size and timing of such future surface disturbing activities is unknown at this time, but they <br /> would be dispersed both in time and in location. The appropriate agency would analyze these activities <br /> for potential environmental effects when proposed by GCCE and authorized by the appropriate federal <br /> agency and/or LPC with conditions of approval as determined by the agency. If the potential <br /> environmental effects are similar to those analyzed in this EA, no further NEPA analysis would likely be <br /> required. <br /> Where applicable, information from previous EAs has been incorporated by reference into this discussion <br /> (see Section 1.1.
