Table 2-3: Summary of Impacts and Mitigation Measures for the Proposed Action and No Action Alternative, p 1 Proposed Action No Action Potential Impact Mitigation Measures Potential Impacts Land Use and Recreation � Temporary disturbance to upland bird hunting in project vicinity � Approximately 47 acres impacted by new roads, 93 acres impacted by tower construction, and 25 acres of poplar trees cut and converted to agriculture compatible with the transmission line Geology, Soils, and Seismicity � Removal of vegetation and disturbance to underlying soils in an area of up to 222 acres � Operation and maintenance activities could increase erosion potential along the project corridor � Locate towers and roads so as not to disrupt irrigation circles, where possible � Locate structures and roads outside of agricultural fields, orchards, and vineyards, where possible � Coordinate with landowners for farm operations, including plowing, crop dusting, and harvesting � Redesign irrigation equipment and compensate landowner for additional reasonable costs where new right-of-way needs to be acquired � Compensate farmers for crop damage and restore compacted soils � Control weeds around the base of the towers � Keep gates and fences closed and in good repair to contain livestock � Minimize vegetation removal � Avoid construction on steep slopes where possible � Properly engineer cut-and-fill slopes � Install appropriate roadway drainage to control and disperse runoff � Ensure graveled surfaces on access roads in areas of sustained wind � Develop additional mitigation measures (using a certified engineer) between corridor miles 39 and 41 due to the presence of an active landslide in the vicinity of tower 40/3 � Apply erosion control measures such as silt fence, straw mulch, straw wattles, straw bale check dams, other soil stabilizers, and reseeding disturbed areas as required � Regularly inspect and maintain project facilities, including the access roads, to ensure erosion levels remain the same or less than current conditions � No impact � No impact
Table 2-3: Summary of Impacts and Mitigation Measures for the Proposed Action and No Action Alternative, p 2 Proposed Action No Action Potential Impact Mitigation Measures Potential Impacts Streams, Rivers, and Fish � Potential transport of sediment to fishbearing waters � Potential accidental spills of construction materials into waterways � Potential dry wash crossing and culvert installation � Potential blasting near fish-bearing waters � Implementation of vegetation management techniques Vegetation � Proposed project would temporarily disturb 121 to 134 acres depending on the number and location of conductor tensioning sites � Temporary impact to 24 to 27 acres of native plants and 4 acres of cryptogramic crusts; permanent impact to 12 acres of native plants and 2 acres of cryptogramic crusts � Establishment of noxious weeds � Vegetation loss due to fire � Use erosion control methods during construction (see mitigation measures for Geology, Soils, and Seismicity) � Develop and implement a Spill Prevention and Contingency Plan � Install water and sediment control at dry wash crossings and construct culverts per WDFW guidelines � Avoid blasting within 200 feet of streams when salmon eggs or alevins are in gravels � Follow BMPs defined in Vegetation Management Plan � Locate transmission line as close as possible to existing lines to minimize additional clearing � Utilize existing access roads to reduce need for new access roads; limit construction equipment to designated construction areas � Avoid placing towers in riparian zones � Keep vegetation clearing to a minimum � Reseed areas temporarily disturbed in higher quality shrub-steppe with native grasses and forbs � Minimize disturbance to native species during construction to prevent invasion by nonnative species � Conduct pre- and post-construction noxious weed surveys; enter into active noxious weed control programs � Wash vehicles that have been in weed-infested areas � Use certified weed-free mulch � Equip all project vehicles with basic fire-fighting equipment, including extinguishers, shovels, and other equipment deemed appropriate � No impact � No impact
