Washington, D.C. 20585 Abstract: This Final Environmental Impoct Statement (FEIS) responds to comments on the Draft Environmental Impact Statement (DEIS) (DOE/EIS-0086-D, February 1982) and includes any necessary additions and corrections. The supporting information furnished in the DEIS should be reviewed and is incorporated herein by reference. This FEIS assesses the potential impacts associated with the proposed finalization of prohibition orders for Units I, 2, and 3 of the Salem Harbor Generating Station, located in Salem, Massachusetts. If finalized, the prohibition orders would prohibit the utility from using either natural gas or petroleum products as a primary energy source in the affected units; the utility proposes to conform to the orders by returning Units I, 2, and 3 to burning low-sulfur coal. The utility has commenced the process of converting to coal, and on March I, 1982, initiated limited coal burning at the plant under the provisions of a Delayed Compliance Order issued by EPA on February 9, 1982. Major issues of environmental concern relating to the conversion have been determined through the public scoping process and through discussion with other concerned agencies, and were found to include air and water qua lity, noise, and waste storage and disposal. These issues, as well as reasonable alternatives in the areas of plant conversion options, fuel type, air and water po llution control, ash disposal, and transportation, are discussed in the DEIS. In an effort to avoid excessive paperwork and costly reproduction, the DEIS text has not been reprinted in the FEIS. SUMMARY INTRODUCTION The Salem Harbor Generating Station is in Salem, Essex County, Massachusetts, about 15 miles northeast of Boston, on a 60-acre site adjacent to Salem Harbor, a branch of Massachusetts Bay. Three of four units at the plant were designed to burn oil or coal as the major energy source; the fourth unit was designed to burn oil only. The units were converted to oil firing exclusively in 1969; they have continued to burn oil since that date except for a short period in 1974- 1975 following the oil embargo when they were reconverted to burning coal. The three, Units I, 2, and 3, are presently fired exclusively on oil. Units I, 2, and 3 have coal handling and firing equipment in place, except for the oil only burners on Unit I which will be replaced as part of the coal conversion project. A supply of high-ash coal remains on hand from the 1974- 1975 coal burn. On Apri I 3, 1980 (45 FR 22 1 83), the Department of Energy (DOE) published proposed prohibition orders for Units I, 2, and 3 at the facility under the Powerplant and Industrial Fuel Use Act of 1978 (FUA), as amended. Following enactment of the Omnibus Budget Reconciliation Act of 1981 (OBRA), which amended FUA to allow powerplant owners and operators to certify to FUA's required technical and economic feasibility findings, the utility elected to so certify. DOE then reissued prohibition orders for Units I, 2, and 3 on December 7, 1981. If the proposed prohibition orders are finalized, they would prohibit the units from using petroleum as their primary energy source. In this event, the New England Power Company, owner of the plant, proposes to return Units 1, 2, and 3 to burning a low-sulfur coal. A Draft Environmental Impact Statement (DE IS) on the proposed conversion of Salem Harbor was published in February 1982 (DOE/EIS-0086-D). This Final Environmental Impact Statement (FE IS) has been prepared by the Office of Fuels Programs, Fuels Conversion Division of the Economic Regulatory Administration of DOE as part of DOE's responsibility under the National Environmental Policy Act (NEPA). DOE has determined that issuance of the prohibition orders is a major Federal action significantly affecting the quality of the environment, and that an EIS is required. Major issues relating to reconversion of the plant to coal have been determined through the public scoping process and through discussion with other concerned agencies, especially the U.S. Environmental Protection Agency (EPA), Region I; the Massachusetts Department of Environmental Quality Engineering (DEQE); and the Massachusetts Executive Office of Environmental Affairs. In addition, appropriate comments on the DEIS for Salem Harbor and on the Draft Northeast Regional EIS (NEREIS) were considered. Issues of concern include air quality, water quality, noise, and waste storage and disposal. These issues, as we ll as reasonable alternatives to the utility's proposed reconversion to a low sulfur coal as the major energy source, are discussed. in the DEIS. No new or substantive issues were raised during the comment period on the DEIS. PURPOSE OF AND NEED FOR ACTION The oil embargo of 1973-1974 brought into sharp focus the nation's dependence on imported oil. The Energy Supply and Environmental Coordination Act (ESECA) was passed by Congress in 1974 in response to the embargo. This was superseded by FUA in 1978. One of DOE's responsibilities under FUA is to identify existing powerplants that could most read ily convert from use of petroleum products to another fuel. A group of facilities selected included those that had been originally designed to burn coal, but that had subsequently switched to oil or gas. The Salem Harbor Generating Station is one of these powerplants. Return of Units I, 2, and 3 to coal burning would save about 3.2 million barrels of oil per year over the remaining 15 or so year life of the units, and would contribute to lessening the country's dependence on imported oil. ALTERNA TIVES As noted in the Council on Environmental QuaHty's (CEQ) regu lations on preparation of environmental impact statements, the analysis of alternatives is the heart of an EIS. This FEIS includes discussions of reasonable alternatives to the proposed action, which is finalization of the proposed prohibition orders. Issues of concern, as identified in the scoping process and in discussions with other agencies, are stressed. DOE's alternatives under FUA, as amended by OBRA are restricted to two: I) to issue the Prohibition Orders, or 2) to not issue the orders. Under either of these alternatives, the utility has several options as noted in the following paragraphs and as discussed in the DEIS. The uti Iity's preferred option if the proposed prohibition orders are finalized is to convert the three units at the Salem Harbor Generating Station to burning low-sulfur coal. Unit 4 is not coal-capable and would continue to burn oil. Alternatives include no action, under which the utility could continue to burn oil; the utility's proposed plan--reconversion to low-sulfur coal; use of alternative fuels; alternative pollution control methods; alternative ash disposal methods; and alternative transportation methods. No Action Under the no action alternative, the utility could elect to continue burning oil, could convert to coal without a prohibition order, or could retire the plant. i i Proposed Conversion Under the utility's proposed response to the prohibition orders, the Salem Harbor Generating Station would return to burning a low-sulfur coal (1 .5 percent sulfur) in three units. This would require about 870,000 tons of coal per year and would save approximately 3.2 million barrels of oil annually. The coal would be brought to the site by a 36,000-ton collier and would require about 25 unloadings per year. EPA Region I issued a Final Delayed Compliance Order (DCO) on February 9, 1982, which facilitates the conversion by allowing the station to exceed currently permitted limits for particulate matter (PM) emissions for the period the DCO is in force (not to exceed 46 months from March I, 1982). These increased emissions would maintain primary National Ambient Air Quality Standards (NAAQS) and would be reduced to within SIP limits as soon as new precipitators could be purchasedand installed and a new, approximately 450-foot stack constructed. A second critical element of the utility's proposed conversion is implementation of an Oil Conservation AdjusJment (OCA) to finance the conversion. Under Massachusetts law the OCA permits the utility to establish the cost of oil and the cost of coal on a quarterly basis and to reserve two-thirds of the cost differential for paying the costs of the conversion and taxes.
