<br />, <br /> <br />......~ <br /> <br />~. <br />'~.:~) <br /> <br />The following issues have also been identified and wf1l be topics for the planning investigation. We will discuss these issues fn future <br />newsletters: <br /> <br />Social / Eeonom Ie <br /> <br />How many U. S. Forest Servi ce grazi"9 <br />allotments would be affected and to what <br />extent? <br /> <br />How would Dunham Point affect logging <br />and drilling operations managed by the <br />U.S. Forest Service? <br /> <br />Will the project be pleasing to the eye <br />or waul d "t be an "eye-sore"? <br /> <br />Is this project economically and <br />environmentally feasible? (This is the <br />purpose of OUf study.) <br />How can local people be employed in the <br />construction of the project, when there <br />are unionized construction companies <br />contracted to do the work? ItIw do local <br />people acquire the skills required for <br />union jobs? /i:)w many jobs would be <br />available during construction and what <br />kinds? How many jobs would be created <br />in order to operate the powel"plant and <br />what ki nds? <br />Can the Cortez-Dolores vicinity <br />withstand all the development proposed <br />for the area (e.g., carbon dioxide <br />plant. Colorado-Ute power system. McPhee <br />Dam construction, HcElmo Creek salinity <br />control project)? For example. what <br />will this development do to the <br />traditional nJral quality of life? ~Iill <br />[)Jnham Point interact wi th other <br />proJects to create a "boomtown" <br />situation? <br />How will McPhee Reservoir fluctuations <br />affect developed and di spersed recrea- <br />tion for which the Forest Service is <br />responsible? Would revenues from poten- <br />tial l'ecreational activities be <br />impacted? <br />What is the best way to get infon;tation <br />about the project to the local public? <br />What cOA:MJnity groups should be involved <br />in the planning process? <br />If the transmission lines tie into the <br />system near Lost Canyon, would there be <br />a major impact on the local population <br />in relation to the two new 345-kv <br />lines? Would relocation of Lost Canyon <br />residents be necessary? If not, what <br />would be the impact on the individual <br />and social welloobeing of having trans- <br />mission lines running through private <br />residences? <br /> <br />WhY wasn I t Dunham Poi nt addressed at the <br />time Congress granted approval tor the <br />Dolores Project? <br /> <br />Engineering <br /> <br />If McPhee has winter ice. would the <br />peaki ng operation affect the ice? <br /> <br />How soon could the project be <br />constructed? <br /> <br />Where would the operation personnel be <br />housed? <br /> <br />Would the facilities be underground? <br /> <br />What would the penstock size be? <br /> <br />Is the Dunham Point site geologically <br />stab~e (i.e., the r~orrison Formation)? <br />How does this project relate to Federal <br />water and energy poJicies? <br />Would there be a problem with sediment <br />and erosion in the forebay due to rapid <br />drawdown? <br /> <br />Would the temperature of ~1C.lter returning <br />to r~cPhee after power generation have an <br />effect on McPhee Reservoir (e.g., <br />fishery, turbidity, ice conditions)? <br /> <br />Where would spol1 material from penstock <br />tunnel construction be disposed of? <br /> <br />Water <br /> <br />Ho\1 would implementation of Dunham PcJnt <br />affect irrigation and water rights from <br />McPhee? ' <br /> <br />Would use <br />rigation <br />affected? <br /> <br />of Dolol"es River water for ir- <br />and other pUYlloses be <br /> <br />Woul d storage ri ghts b~ !.:\.qUi red for use <br />of the water and 'for evapoi"'ation losses? <br /> <br />Power <br /> <br />These issues will be the main topic of <br />discussion at the next Planning Team <br />meeti ng on Septembe~. 1 <br />Where would the transmission lines <br />(corridor) be located? <br />What would the plant's operation crite- <br />ria be? When would pumping and power <br />generation occur? <br />How does the overall power system work? <br />Where would the generated power go to <br />and who would manage it? <br /> <br />Who would have first cracK at purchasing <br />and using the power - private cOlllpanies <br />such as Colorado Public service Company, <br />or public users such as the City of <br />Delta. COlorado? <br /> <br />Who are the Colorado River Storage Pro- <br />ject (CRSP) users? <br /> <br />What is a baseload, facility? '_ <br /> <br />Where are the baseload facilities? <br /> <br />, <br />How many lines would be -required to tie <br />Dunham Point to existing transmission <br />lines? <br /> <br />Why is the project effective. since it <br />uses more power than it generates? <br /> <br />Who beneti ts? <br /> <br />Would power rates be affected? <br />How does the Western Systems <br />Coordinating Council tit into this <br />study. since they review the tranSlllis- <br />sion line capacities? <br />Who bears the costs of the project? <br /> <br />. <br />
