Lawrence, Acres Project Manaqer) Thank you Eric and good morni_ng 1 adi es and gent I emen. Acres and those of our subcontractors present are pleased to be given this opportunity to participate iH these meeti.ngs. I will begin by introducing the staff. Mr .. Chuck Debelius is Deputy Project Manager, Mr. Jim Gill is our Anchorage Resident Manager, supervising project activities in Alaska, Dr. John Hayden is Technical Study Director, Dr. Don McDonald is a senior member .of Acres staff who is chainnan of our in-house technical review panel, Mr. Virendra Singh, Supervisor of geotechnical studies, Stewart Thompson, Supervisor of geologic studies and Kevin YfJung, Supervisor of environmental - Studies. Representing our subcontractors I am also pleased to introduce Dr. Jon Lovegreen, , . and Dr. Maury Power of Woodward Clyde Consultants and Mr. Jeff Barnes and Dr. Vince Lucid of Terrestrial Environmental Specialists. At this point .I would like to sununarize the philosophy of the Acres Plan of Study for. Susitna, the organization of the study team and the basic approach to the study. The basic objectives of the POS are: 1. Assess the technical, economic and financial feasibility of the Susitna Project to meet future power needs of the Railbelt Region. 2. Evaluate the environmental consequences of designing and constructing the Susitna Project. and 3. Subject to establishing project feasibility, file a completed 1 i cense app 1 i cation with the Fed era 1 Energy Regula tory Commission I I I I I I I I I I I I I I I I [I ll. I The study was conceived as a 30 month effort commencing in January 1980 and culminating in June 1982 with submission of the license application to the Federal Energy Regulatory Commission· for development of the Susitna Hydroelectric Project. I would like to stress once·more that the decision to submit this application will be predicated on establishment of technica1 and economic feasibility of the project, on a determination that the environmental impact of the development will not be unacceptable and that the project development will be in the b~st interest of the State of Alaska for meeting the future power needs of the Railbelt Region. In this regard the State legislature has mandated that reports be submitted by the Power Authority in March 1981 and April 1982 to justify respectively, continuJtion of studies and submission of the license application~ on the basis of the results of studies undertaken. To undertake the many complex and interrelated specialist aspects of the study, Acres has assembled in-house & group that we call Task Supervisors. We will be discussing later today the specific project tasks. I have already introduc~d introduced some of the key participants., Other Task Supervisors not present are individually responsible for supervision of the remaining study activities including hydrology, project design development, transmission, licensing, and marketing and financeG Task Supervisors have at their disposal the necessary support staff and company specialists to assist in accomplishing their study goals. Those of us that are here will act as spokesmen for those who are not. To complete the project team, Acres has also entered into a number of subcontracts with appropriate specialist firms. These are: --R&M -To undertake field surveys, and to provide assistance in hydrologic -and geotechnical field work and studies --CIRI/H&N -for camp construction and operation and assistance in permitting and land status studies I I I I I I I I I I I I I I I IIi I I I I . --FM&A -providtng consulting services on management of camp construction, operation and logistical planning and project management cost estimating and scheduling activities --wee -to provide consulting services on load forecasting and on seismologic and earthquake studies and field exploration --TES -undertaking, together with a number of Alaska-based and other specialist sub-consultants, the project environmental studies. --RWR&A (IECO) -providing consulting services on transmission line corridor selection and preliminary design The Alaska Department of Fish and Game, through RSA's directly with the Power Authority is also providing services in assembling field data on fisheries and big game. When originally conceived, the Plan of Study or POS was subdivided into thirteen separate activities or Tasks. The scope and responsibility for some of these Tasks has since been modified. Notably, detailed studies of alternatives to the Project, originally under Acres Task 1, were terminated in June of 1980 and are now the subject of a separate study by others. Task 1 has therefore been confined to a review by Acres and its subcontractor WCC of the Railbelt energy forecasts prepared by the Institute of Social and-Economic Research, and development of peak load for·ecasts for the Region. As a result of this change, the scope of Task 6 design development studies was also modified to include the early system generating planning data necessary to support the establishment of appropriate sizing and timing of the Susitn~ Project, and comparison of alternative Susitna Basin developmentse The scope of Task 8 transmission studies was also modified to take account of separate studies of a transmission intertie between Anchorage and Fairbanks. The responsibility for Task 12 public participation was also transferred directly to the Power Authority under the able direction of Ms. Nancy Blunck. I I I I I I I I I I I I I I I I I ._: I I.: ' ' •• ~,;;o.o This concludes my introductory remarks on the Susitna Plan of Study and the study team. .After the break we will discuss in more detail the objectives, scope and progress to date of the following Tasks. Task 3 Hydrology (by Dr. John Hayden of Acres) Task 4 Seismic studies (by Virendra Singh of Acres) Task 5 Geotechnical Exploration (by Jim Gill of Acres) Task 7 Environmental studies (by Kevin Young of Acr.es) To provide a.logical sequence for these presentations, we will start with the seismic and geotechnical studies, followed by hydrology, environmental and transmission. After lunch, Chuck Debelius, John Hayden and I will describe our efforts to date under Task 6 in which we have been studying the Susitna Ba~in development potential, alternatives and selection of the preferred development plan.
