The original EBS report (Final Phase I Environmental Baseline Survey for Leasing Nellis Air Force Base Land for Construction and Operation of a Solar Photovoltaic System, Clark County, Nevada) dated September 2006 (Nellis AFB 2006) was prepared for the lease of 212 acres for the same project. The SPS will be used as a main power source for Nellis AFB. The property in consideration is a portion of Area III, and is located near the northern boundary of Nellis AFB, Clark County, Nevada (see Figures B1 and B2; Appendix B). This report was prepared and the site reconnaissance was conducted according to Air Force Instruction 32-7066: Environmental Baseline Surveys in Real Estate Transactions and the American Society for Testing and Materials (ASTM) guidelines ASTM E1527-05, which define good commercial and customary practices in the United States for conducting an environmental site assessment of a parcel of commercial real estate with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation, and Liability Act (42 USC 9601). According to information gathered from document searches, interviews, and the site reconnaissance, Gulf South Research Corporation (GSRC) found no evidence of contamination in connection with the subject property, although evidence of contamination on properties to the south and southeast of the subject property was reported in the original EBS (Nellis AFB 2006), and is incorporated here by reference. None of the previously reported contamination sites would pose an environmental risk to the subject property. GSRC recommends that no further environmental studies be conducted for the subject property.
