3449 Small amounts of plant life will of course be disturbed during the eonstruction process, however, all distrubed sites will be revegetated to bring them as close to their pre-existing condition as possible in accordance with Forest Service requirements. Once the project has been completed and begins operation, no adverse impacts are expected to occur to plant and animal life. (Reference Draft Environmental Impact Statement, Attachment I, Chapter 4) (iv) The Applicant Will Present Technical Material Describing And Quantifying The Impact The Proposed Development Will Have Upon Salinity Or Total Dissolved Solids In The Colorado River And Shall Formulate And Propose A PIan For The Mitigation Of Such Impacts. The impacts of the proposed Homestake Phase II Project on salinity in the Colorado River is minimal. The Sundeen & Fifer Report (Attachment 13) indicates a one milligram per liter impact at Imperial Dam. No adverse impacts from increased TDS in Eagle County are foreseen since diversions will be made during peak run-off periods. A 12% reduction in flow in the Eagle River during spring run-off will not increase salinity levels greater than winter levels and will not place any additional burden upon 10cal water or wastewater treatment plants, or other uses. The Colorado River Salinity Forum has adopted a basin-wide approach to salinity. The basin-wide approach intends to allow further development of water resources al10cated to the Upper Colorado River Basin States while reducing salinity through major salinity removal projects. These projects are being constructed through federal funding. Individual diversion projects are not intended to mitigate indirect impacts. Accordingly the Cities will not propose a mitigation pIan until such time as all water users within the basin are assessed on the amount of water consumptively used and wastewater dischargers assessed on the basis of TDS added to the river. The Cities of Colorado Springs and Aurora will stipulate that they will participate in an equal1y proportio- nate share of the mitigating measures to address the salinity issue at such time as all users causing water consumption and salt 10ading in the Colorado Basin share equally in the costs of mitigation. (c) Air Quality: Detail The Impact Of Proposed Development On Ambient Air Quality Of The Area Or Community In Question. Air quality impacts will occur in the source development area only during construction. At that time the appropriate measures will be taken for the control of dust on roads and in the construction area. The DEIS calculates the upper level of TSP impact during construction in Appendix G of Attachment 1 (see also DEIS pages 4-1 to 4-3). The USFS mitigation measures required during construction will sufficiently mitigate air quality impact. (Note that mitigation measures during construction will have incidental benefit of reducing TSP attributable to recreational users.) Air quality in the development area will not be significantly impacted and National Ambient Air Quaility standards will 17
