NO'IICF OF PREPARATION OF ENVn4ONW:NT.O. IMPACT REPORT <br /> PAGE 8 TANC TRANSMISSION I'RO.IECE <br /> ATTACHMENT I <br /> Summary of Potential Issues or Impacts: TANC Transmission Project <br /> Environmental Issue <br /> Area Potential Issues or Impacts <br /> Aesthetics Visual Visual contrast, increased industrial character, view blockage, and skylining resulting <br /> from placement of structures in all project segments. <br /> Impacts to sensitive viewpoints from which the TIP would be visible, including but <br /> not limited to: residences, park and recreation areas, scenic roadways, public lands, <br /> and open space areas. <br /> Agricultural Resources Impacts during the construction phase resulting from the removal of cropland from <br /> production, interference with tilling and irrigation patterns, and /or potential conflict <br /> with agricultural aviators (crop dusters) due to temporary laydown areas, tensioning. <br /> and pulling sites. <br /> Impacts on zoning for agricultural use, Williamson Act contracts, or conversion of <br /> farmland to non agricultural use. <br /> Long-term operational impacts where transmission line structure foundations would <br /> permanently remove active agricultural land out of production and interfere with tilling <br /> and irrigation patterns. <br /> Air Quality Impacts during construction when heavy equipment, support vehicles, and internal <br /> combustion equipment create fugitive dust and /or generate exhaust containing: carbon <br /> monoxide (CO), reactive organic compounds (ROC), nitrogen oxide (NOx), sulfur <br /> oxides (SOx), and particulate matter (PM 10). <br /> Ongoing impacts from emissions and fugitive dust produced during operation and <br /> maintenance activities. <br /> Temporary and long-term impacts from toxic air contaminants that may have localized <br /> effects. <br /> Impacts resulting from violation of the Federal Air Quality Conformity Rule in <br /> nonattainment areas for one or more air pollutants. <br /> Impacts to human and environmental health from non- attainment of the FPA's <br /> National Ambient Air Quality Standards (NAAQS). <br /> Impacts resulting from violations to any areas designated as non attainment for <br /> particulate matter or any other pollutant based on California Air Resources Board <br /> (CARB) or local Air Quality Management District (AQMD) Standards. <br /> Biological Resources Temporary and permanent loss of native habitat, including habitat for special status <br /> species <br /> Disruption in wildlife behavior (e.g., breeding, foraging, roosting, nesting, etc.). <br /> Bird electrocution and collision resulting from contact with overhead transmission <br /> lines. <br /> Direct, permanent impacts to wildlife and plants during construction, operations, and <br /> maintenance activities. <br /> Cultural Resources Impacts to known and unknown prehistoric and historic resources and archaeological sites, <br /> which may he determined to be eligible for the National Register of Historical Places <br /> (NRHP). <br /> Impacts to Traditional Culture Properties (TCPs) or potential TCPs. <br /> Electric and Magnetic Public concern about electric and magnetic field effects of the transmission line. <br /> Fields <br /> Geology and Soils Damage to uncoated steel from highly corrosive soils. <br /> Sedimentation of water features from soil erosion caused by construction and <br /> operation activities. <br /> Impacts from landslides, mudslides, surface rupture, or other ground failure from <br /> seismic activity, particularly where project features are near active faults. <br /> Impacts from soil vol changes or soil compaction due to changes in soil moisture <br /> content and project activities. <br /> Hazards and Impacts from improper storage or handling or hazardous materials and/or hazardous <br /> Hazardous Materials wastes during construct ion, operations, or maintenance activities. <br /> Impacts from leaking or spilling of petroleum or hydraulic fluids from construction <br />
