The studies recommend the construction of two 345-kV transmission cir- cuits from a substation near the project along a route through west- ern Maine into northern New Hampshire and Vermont. The plan will integrate the power produced by the project into the New England Power Pool Transmission System. Five alternate integration plans were identified and studied. Of the five plans, the recommended plan, which calls for the lines to be suspended from a single row of steel towers, has the least environmental impact and is the least costly. INTRODUCTION The site of Dickey Dam is on the upper St. John River just above its confluence with the Allagash River, some 28 miles from Fort Kent, Aroostook County, Maine. As authorized, the dam would be an earthfill structure impounding a reservoir with a storage capacity of 7.7 mil- lion acre-feet for power, flood control, and recreation. Lincoln School Dam is to be located on the St. John River, 11 miles downstream from Dickey. It. is to be an earthfill structure impound- ing 24,000 acre-feet of water. A reregulating dam, Lincoln School will smooth out the fluctuation of flows created by peaking opera- tions at Dickey. Private and public utility engineers had been studying the feasibility of developing a tidal power plant at Passamaquoddy, a system of tidal bays, since 1919. Later they included the upper St. John River in their studies. In April 1961 after 3 years of study and an expendi- ture of some $3 million, the International Joint Commission completed a comprehensive report on the project. The Commission concluded that under conditions existing then the project was not economically feasible. Shortly thereafter, President John F. Kennedy asked that the Commis- sion report be reviewed in light of advanced engineering techniques and prevailing economic conditions. A review report was submitted to the President in July 19 63. It concluded that a different use con- cept for the power, coupled with advanced engineering techniques, favored project feasibility. On July 16, 19 63, President Kennedy directed the Departments of Army and the Interior to make additional studies to supplement the 196 3 report. An Army-Interior Advisory Board on Passamaquoddy and Upper St. John River was formed. The Army Corps of Engineers launched studies leading to the design of the dams and other physical compon- ents of the project. Interior conducted studies on transmission, marketing, and other economic aspects. The studies resulted in a report to the Secretary of the Interior in August 1964. Its recommendations included early authorization of the Passamaquoddy Tidal Project and Upper St. John River Developments and early construction of the project to develop low cost firm power for Maine and peaking power for the remainder of New England. The Secretary submitted a report to President Johnson July 9, 1965, summarizing the studies. Subsequent reviews updated the power bene- fits. The benefit-to-cost ratio for the Dickey-Lincoln School Lakes Project was then found to be 1.81 to 1. -34- The U. S. Congress authorized the Dickey-Lincoln School Lakes Project in Public Law 89-298, the 1965 Flood Control Act. President Lyndon B. Johnson signed the Act into law. Tt became effective October 27, 1965. Planning and design for the Dickey-Lincoln School project began after the project was authorized—but ceased in late 1967 due to lack of funds. These activities resumed in the fall of 1974 when additional funding was provided to the Corps of Engineers. The Flood Control Act of 1944 assigns the authority and responsibility for marketing and transmission of electric power generated at Federal hydroelectric projects to the Department of the Interior (DOI). This authority covers the power not used at the projects themselves. The act also sets forth certain broad criteria for the marketing of this power. Thus, the Corps in 19 7 4 asked the Department of the Interior to con- duct a marketing study and do the transmission system planning, en- vironmental, and location studies. The DOI established separate study teams, one for the marketing and another for the transmission planning, environmental, and location efforts. The DOI will prepare a draft environmental .impact statement on trans- mission aspects of the project as required by the 1969 National En- vironmental Policy Act (NEPA). The Corps is preparing a draft environmental impact statement on the project itself. The two draft statements will be filed separately with the Council on Environmental Quality (CEQ). The Corps draft is to be submitted to the CEQ in June 1977, and the DOI draft in November 1977. The avail- ability of the draft statements will be announced in the Federal Register and in the media. -3- The draft statements will then be combined into a single, final joint Environmental Impact Statement (EIS) for the project and associated transmission facilities. This EIS is scheduled to be filed with the CEQ in June 1978. The DOI has established an office and small staff at Bangor, Maine, to manage and perform planning, reconnaissance, location, and environ- mental activities. The staff at Bangor has written this report. APPROACH Hence, the DOI has undertaken studies in four general areas—marketing, system planning, environmental impacts, and reconnaissance and loca- tion. The four studies, which are briefly described below, are: - Dickey-Lincoln School Project Financial Feasibility Study for Electric Power - Transmission System Planning Study - Alternative Power Transmission Corridor and Environmental Study - Transmission Reconnaissance and Location Study Dickey-Lincoln School Project Financial Feasibility Study for Electric Power The marketing study considers alternative ways of allocating Dickey- Lincoln School power to potential markets in the Northeast region, possible rate schedules for the power, and the establishment of rate levels. These rate levels would assure repayment of the investment in the project, including the cost of: (a) that part of the capital cost of the project allocated to power, and (b) the capital cost of the transmission facilities. All capital costs are repaid with in- terest. The marketing study will consider alternatives and recommend a plan for marketing the power. Results of the marketing study will be pre- sented in a separate report. Further discussion of the marketing study, therefore, is not included in this report. -4- Transmission System Planning Study These
