then be determined for the 100-year evaluation period. This will portrayboth benefits and costs reduced with a corresponding reduction in netbenefits; however the ratio of benefits to costs will remain the same.In the case of the PRT the total benefits and cost were presentworthedto 1984 and then spread over the 100-year evaluation period.These economic evaluation procedures have the effect of evaluating theplans on equal ground.RATIONALE FOR DESIGNATION OF NED PLANThe ~Jational Economic Development (NED) objectives are achieved byincreasing the value of the nation's output of goods and services andimproving national economic efficiency. Based on this criteria the NEDPlan is Plan D, the pressure reducing turbine plus Allison hydropower.This plan would provide net annual benefits exceeding any of the alternateplans. The combination of the PRT with hydropower would allow thedisplacement of exceedingly precious and expensive petroleum products.Although a number of questions regarding implementation of the PRT remainto be resolved between the local utility and Alyeska Pipeline ServiceCompany, these are the responsibility of those organizations. Fundingfor the PRT would be private whereas it would be primarily Federal forthe hydropower portion of the plan. The average net annual NED benefitsover the life of the proposed plan, are $2,391,000.~ATIONALEFOR DESIGNATION OF EQ PLANThe Environmental Quality (EQ) Plan is an alternative which makes themost significant contribution to preserving, maintaining, or enhancingthe cultural and natural resources of the study area. Of the detailedplans considered, none would provide an actual enhancement of theenvironment; however, Plan B (PRT plus diesel), would cause the leastenvironmental damage (LED). Therefore, this alternative has beendesignated the LED plan.The continued use of diesel has the impact of noise and air pollution,but this is relatively minor compared to the impact of hydropowerconstruction. The fact that the generators are already in place, and noadditional units would be required until the mid-1990's, would eliminateany environmental impacts from construction.The pressure reducing turbine would have some minimal impacts fromconstruction, but there would be less impact from noise and pollutionduring operation. Located immediately adjacent to the oil pipeline, thefacility would be in an area that has been previously disturbed. The PRTwould be housed in a building approximately 60 x 170 feet. The totalarea required for the building and grounds would be approximately 1.5acres.49
RATIONALE FOR SELECTED PLANUnder realistic assumptions regarding future economic conditions andfuel costs, Plan D, PRT plus hydropower, is the most economical means ofmeeting the long term future needs of the study area. This plan wouldhelp meet both the short and long term needs of the study area and reducethe current dependence on diesel-fired generation.The PRT would have a much shorter construction period than AllisonLake hydropower allowing for faster implementation. The PRT wouldfunction as a baseload operation with Solomon Gulch and the existingdiesel generators providing back up and peaking capability.Allison Lake hydropower would come on line in 1990 at a time whenadditional energy, above and beyond the capability of Solomon Gulch andthe PRT would be needed. The project would meet the estimated energy andcapacity needs until 1995 and 1998 respectively. In 1995 additionalenergy would come from either diesel generation or possibly additionalhydropower.The following table provides a summary of the Federal and nonfederalfirst cost apportionment for the selected plan.First Cost (October 1980 Dollars)FederalPRT -0-ALLISON HYDRO $30,871,000Non-Federal$9,700,000$3,430,000The above cost apportionment for Allison Lake hydropower is inaccordance with the President's proposed cost-sharing policy. Thispolicy requires 10 percent State participation in Federal projects havinga "vendible" output.PUBLIC INVOLVEMENT AND COORDINATIONThroughout the course of this study public involvement wasaccompl i shed primar"ily through three publ i c meeti ngs hel d at vari oustimes during the study process. The purpose of the earlier meetings wasto obtain input from the public to help direct the study, where thelatter meeting was to receive comments on the results.Input from State and rederal agencies was obtained by either directcontact or through the State Clearing House. Nearly 200 copies of thedraft report were sent to various agencies, special interest groups, andinterested individuals.50
