    SUMMARY: Today's notice is issuing the United States Department of 
    Energy (the Department) Office of Energy Efficiency and Renewable 
    Energy's Record of Decision on the Southeast Regional Wastewater 
    Treatment Plant Facilities Improvements Project and Geysers Effluent 
    Pipeline Project Environmental Impact Statement/Environmental Impact 
    Report prepared by the United States Department of Interior, Bureau of 
    Land Management (the Bureau) and the Lake County California Sanitation 
    District. The Department, as a cooperating agency, adopted the 
    Environmental Impact Statement as DOE/EIS-0224 on January 11, 1995 
    after independent review. This Record of Decision is pursuant to the 
    Council on Environmental Quality regulations (40 Code of Federal 
    Regulations Parts 1500-1508), which implement the procedural provisions 
    of the National Environmental Policy Act, and the Department's National 
    Environmental Policy Act regulations (10 Code of Federal Regulations 
    Part 1021). The document was also prepared to comply with the 
    California Environmental Quality Act, hence the impacts; the proposed 
    project will be beneficial to the public by extending the life of the 
    Southeast Geysers Geothermal Field providing more electricity for 
    consumption, and the proposed project will be beneficial to the public 
    by bringing the Southeast Regional Wastewater Treatment Plant into 
    compliance with California Regional Water Quality Control Board Waste 
    Discharge Requirements and enable lifting of the Board's 1991 Cease and 
    Desist Order and associated moratorium. The final Environmental Impact 
    Statement was published August 25, 1994.

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        Since early 1992, the Lake County Sanitation District has pursued a 
    joint venture with the geothermal industry, specifically the Northern 
    California Power Agency, Calpine Corporation (Calpine), and Pacific Gas 
    and Electric Company, to develop a plan for disposal of secondary-
    treated effluent from the Southeast Regional Wastewater Treatment Plant 
    (the Plant) near the City of Clearlake, California, in the Southeast 
    Geysers Geothermal Steam Field. In early 1994, Union Oil Company also 
    became a partner in the joint venture. That plan includes upgrades to 
    treatment facilities at the Plant, construction of a pipeline to divert 
    raw lake water from Clear Lake to be added to the effluent, 
    construction of a 26-mile 24-inch diameter pipeline to the Southeast 
    Geysers, addition of effluent from the Middletown Wastewater Treatment 
    Plant, pump stations, secondary distribution lines for conveying the 
    effluent to injection wells in the steam field, and construction of 
    storage regulating tanks. The project is located primarily in Lake 
    County, California, and also in part of Sonoma County, California.
        The project is intended to alleviate two circumstances. (1) It 
    would resolve treatment and disposal deficiencies and would provide 
    additional capacity at 
    
    [[Page 53361]]
    the Plant, thereby bringing the Southeast Regional Wastewater System 
    into compliance with California Regional Water Quality Control Board 
    Waste Discharge Requirements and enable lifting of the Board's 1991 
    Cease and Desist Order and associated moratorium. Prior to development 
    of this plan, a cost-effective and environmentally acceptable means of 
    disposing treated wastewater effluent could not be identified. (2) The 
    project would also provide a dependable source of water for injection 
    into the Southeast Geysers steam field to support steam reservoir 
    pressure that is used to generate electric power. Since about 1987, 
    declines in steam production have occurred because of lower steam 
    pressure throughout the Southeast Geysers Geothermal Field. The 
    wastewater effluent, combined with diverted lake water, would mitigate 
    the decline and allow continued geothermal energy production in this 
    area for 25 or more years at higher production levels than would occur 
    otherwise.
        Implementation of the plan involves multiple federal, state and 
    local agencies. Federal participation includes permitting by the 
    Bureau, as portions of the project in the Southeast Geysers require 
    granting of Rights of Ways on federal lands managed by the Bureau. The 
    Department will provide financial assistance grants to the Lake County 
    Sanitation District for construction of the project. The Department has 
    provided funding for the project in the past for early engineering 
    design work and for preparation of environmental documentation. 
    Additional funding may be provided by the U.S. Environmental Protection 
    Agency, U.S. Department of Agriculture Rural Development 
    Administration, and the Department of Commerce Economic Development 
    Administration. Other federal agencies with permitting or consultation 
    requirements include the U.S. Fish and Wildlife Service, U.S. Army 
    Corps of Engineers, Advisory Council on Historic Preservation, and 
    Occupational Safety and Health Administration.
    
    Environmental Considerations
    
        The Bureau serves as the lead federal agency under the National 
    Environmental Policy Act for the Environmental Impact Statement. The 
    Department is a cooperating agency. The Lake County Sanitation District 
    is the lead agency representing local authorities and assuming 
    responsibility for compliance with or coordination of State of 
    California requirements for the project including preparation of a 
    joint Environmental Impact Report, pursuant to requirements of the 
    California Environmental Quality Act. The following summarizes the 
    specific key actions taken to comply with the National Environmental 
    Policy Act and the California Environmental Quality Act.

    Bureau of Land Management Record of Decision--February 16, 1995
    
        Certification of the Environmental Impact Report by the Lake County 
    Planning Commission included recommendations for implementation of a 
    Mitigation, Monitoring and Operation Plan, pursuant to requirements of 
    the California Environmental Quality Act, and drawn from mitigation 
    measures identified in the Draft and Final Environmental Impact 
    Statement/Environmental Impact Report. The re-certification of the 
    Environmental Impact Report by the Lake County Sanitation District 
    Board of Directors includes the Mitigation, Monitoring and Operation 
    Plan, which establishes enforceable conditions of the County Use 
    Permit. Sonoma County also adopted mitigation measures which are 
    included in the Union Oil Company general use permit. The Environmental 
    Impact Statement/Environmental Impact Report did not distinguish 
    between mitigation and monitoring responsibilities of the Bureau of 
    Land Management and Lake and Sonoma Counties so the Bureau appended the 
    Mitigation, Monitoring and Operation Plans to their Record of Decision. 
    The Bureau Record of Decision is included here as Appendix A. 
    Mitigation measures identified in the Environmental Impact Statement/
    Environmental Impact Report and designated mitigation measure 
    enforcement authorities are included in the Bureau Record of Decision. 
    Therefore, the Department will not prepare a separate mitigation action 
    plan.
        The Bureau signed a Record of Decision for the project which 
    specifies that the right-of-way grants which implement the decision 
    would be issued only upon completion of the section 106 process under 
    the National Historic Preservation Act, and completion of conference 
    procedures with the U.S. Fish and Wildlife Service for the project. The 
    Department, the Environmental Protection Agency, the California State 
    Water Resources Control Board, and the Lake County Sanitation District 
    entered into a Programmatic Agreement with the Advisory Council on 
    Historic Preservation and the California State Historic Preservation 
    Office for protection of cultural resources on all parts of the project 
    according to section 106 of the National Historic Preservation Act. The 
    Programmatic Agreement requires identification and 
    
    [[Page 53362]]
    evaluation of cultural resources that may be disturbed by the action 
    and mitigation where significant resources would be disturbed in 
    consultation with historic preservation officials. Implementation of 
    this agreement completes the consultation requirements of sections 106 
    and 110 of the National Historic Preservation Act for the project. 
    Mitigation measures to avoid or reduce impacts are listed in the final 
    Environmental Impact Statement and the attached Bureau Record of 
    Decision. The Bureau has formally requested a conference with the U.S. 
    Fish and Wildlife Service regarding potential impacts to the California 
    red-legged frog (Rana aurora draytonii). This species is proposed for 
    listing as endangered and was scheduled to be listed early in 1995. 
    Section 7 of the Endangered Species Act requires conferencing but not 
    formal consultation for proposed species. A proposed species is one 
    that has been proposed for listing as an endangered species. A 
    candidate species is under evaluation to determine whether to propose 
    it for listing as an endangered species. If the evaluation is in the 
    early stages it would be a candidate 2 species, when enough information 
    is available to propose the species for listing it would be called a 
    candidate 1 species. A biological assessment is not required for 
    proposed or candidate species. However, the Bureau prepared a 
    biological assessment of potential impacts to a number of species 
    including the California red-legged frog as well as federal candidate 1 
    plant species including the Lake County dwarf flax (Hesperolinon 
    didymocarpum), the Socrates Mine jewelflower (Streptanthus brachiatus 
    ssp. brachiatus), and the Freed's jewelflower (Streptanthus brachiatus 
    ssp. hoffmanii). The project impacts were determined to be ``not likely 
    to adversely affect'' the plant species listed above. Additional plant 
    and animal species are evaluated in the biological assessment resulting 
    in ``no effect'' determinations. Surveys for the red-legged frog have 
    discovered no specimens in the project impact area. If the species is 
    discovered in the impact area during construction, a number of 
    mitigation measures would be instituted to lessen the impact. Only one 
    potential habitat area, a stream crossing at Bear Creek, has the 
    potential to result in permanent loss of habitat. The U.S. Fish and 
    Wildlife Service concurred with the Bureau determination that the 
    project is not likely to adversely affect the red-legged frog. 
    Mitigation measures reducing the project's potential impact to the red-
    legged frog and other special status plant and animal species and their 
    habitats to less than significant levels are included in the final 
    Environmental Impact Statement and the Bureau Record of Decision. 
    Additional mitigation measures such as alterations to the pipeline 
    route or pipeline design to avoid or reduce impacts to the species or 
    their habitat may be implemented based on the U.S. Fish and Wildlife 
    Service requirements if new information reveals effects of the proposed 
    action that may affect listed species in a manner or to an extent not 
    considered.
    
    Alternatives Considered in the Decision-Making Process
    
    Preferred Alternative and Supporting Rationale and Trade-offs
    
        The preferred alternative is the proposed project identified in the 
    Environmental Impact Statement/Environmental Impact Report with 
    mitigation measures. This alternative was selected: (1) Because it will 
    provide a means for the Lake County Sanitation District to resolve its 
    treatment and effluent disposal deficiencies, bringing the Southeast 
    Regional Wastewater Treatment Plant into compliance with its waste 
    discharge permit requirements, as required by law and (2) because it 
    will support continued geothermal steam energy production in the 
    Southeast Geysers, which has been in decline since 1987. The preferred 
    alternative meets the specific objectives of the project that are 
    consistent with provisions of the Federal Land Policy and Management 
    Act of 1976, Geothermal Steam Act of 1970 and other federal laws 
    regulating geothermal energy use in the Southeast Geysers. The area 
    currently contains extensive geothermal energy development that is 
    regulated by the Bureau. The project with mitigation provides a method 
    of continued long-term use of the natural heat resource for electrical 
    energy generation. Continued use of the geothermal resources of the 
    Southeast Geysers is consistent with federal policy for use of 
    alternative energy resources and the specific land management 
    objectives of the Bureau in this Resource Area. Additionally, this 
    alternative provides an effective means of treated effluent disposal, 
    which is consistent with federal policy promulgated by the U.S. 
    Environmental Protection Agency (EPA) pursuant to the Clean Water Act. 
    By providing a remedy that would remove the current Cease and Desist 
    Order for the Plant, the project would support compliance with federal 
    law and EPA wastewater discharge requirements. Significant impacts of 
    the preferred alternative can be reduced to less-than-significant 
    levels through implementation of mitigation. Two impacts were 
    identified in the Environmental Impact Statement/Environmental Impact 
    Report as significant and unavoidable. Impact 5.2.2.1 identified a 
    short-term impact on water quality by construction of a road and 
    placement of fill in an unnamed tributary of Bear Creek. The Bureau has 
    identified specific mitigation measures in the draft Environmental 
    Impact Statement/Environmental Impact Report and final Environmental 
    Impact Statement/Environmental Impact Report which would reduce the 
    risk of slope erosion and silt deposition in the creek in the short 
    term and in the long term. Impact 5.2.3.13 identified long-term 
    cumulative loss of montane hardwood woodland, montane conifer woodland 
    and mixed chaparral that potentially provide habitat for the loggerhead 
    shrike, a federal candidate 2 species. The same area may also be 
    habitat for the Cooper's hawk and sharp-shinned hawk, both California 
    species of concern and protected under State Code. Actual presence of 
    these species at the area of potential effect has not been determined 
    and, therefore, the impact is not definitive. Mitigation has been 
    included that would require preconstruction surveys to determine if the 
    species is present. Mitigation would potentially include establishing 
    habitat preservation plans in the region for these species. These 
    habitats are relatively widespread in the area, providing opportunities 
    for preservation.
        Major public concerns relate to induced seismicity, spills and loss 
    of habitat. Seismicity: Evidence suggests that injection of water into 
    the Geysers steam field does induce seismicity in the form of 
    microseismic events which register less than 3.0 on the Richter Scale. 
    This magnitude of seismic event is not great enough to cause any damage 
    to a structure and therefore is not considered to have a significant 
    environmental impact. The Bureau noted in their Record of Decision that 
    injection may be stopped if the link to larger magnitude earthquakes 
    becomes clear. Spills: The public is concerned that effluent from a 
    pipeline break could result in damage to waterways and impacts to plant 
    and animal species. Pipeline monitoring, pipeline design and the 
    mitigation measures in the Environmental Impact Statement and 
    mitigation plans will reduce the risk and impact of a spill to less 
    than significant levels. Loss of Habitat: There 
    
    [[Page 53363]]
    will be temporary loss of habitat during construction and a permanent 
    loss along the pipeline corridor. Mitigation measures reduce habitat 
    loss to a minimum.
    
    Environmentally Preferred Alternative and Rationale for Rejection
    
        The environmentally preferred alternative identified in the 
    Environmental Impact Statement/Environmental Impact Report was the 
    proposed project with the exception that Route Alternative F would be 
    implemented. Route F differs from the preferred alternative only in the 
    location of a 5,000-foot segment of the pipeline. Route F included 
    construction of the Geysers Effluent Pipeline in about 3,700 feet of 
    existing roadway and without an access road for about 2,000 feet 
    between the Bear Canyon Power Plant and the Northern California Power 
    Agency M-Site. This alternative would have eliminated the need to 
    construct a new road and place fill in the course of the unnamed 
    tributary of Bear Creek, features which created a potential for 
    significant unavoidable environmental impacts.
        The environmentally preferred alternative was rejected because the 
    advantages of having continuous road access to the pipeline in the 
    rugged terrain outweighed the environmental impacts. Mitigation 
    included in the Bureau Record of Decision reduces impacts 
    substantially. While residual impacts on water quality and permanent 
    loss of possible habitat of sensitive bird species would result from 
    the preferred alternative in this segment of the pipeline route, these 
    impacts are deemed acceptable in consideration of the advantages 
    offered by better access to the pipeline. The preferred project also 
    would result in connection of two roads that currently dead end. 
    Connection of the roads would provide improved access for emergency 
    vehicles to the Southeast Geysers.
    
    Other Alternatives and Rationale for Rejection
    
        The Lake County Sanitation District rejected all alternative forms 
    of wastewater disposal described in the Environmental Impact Statement/
    Environmental Impact Report because of significant potential 
    environmental impacts and costs. These considerations were reviewed by 
    the Bureau and the Department. The Lake County Sanitation District had 
    primary responsibility for the rejection of other disposal method 
    alternatives. In making its decision about providing partial funding 
    for the project, the Department considered the environmental effects of 
    the project and all alternatives, including alternative disposal 
    options.
        The No Action Alternative was rejected because it would not allow 
    the Lake County Sanitation District to resolve its wastewater treatment 
    deficiencies. Specifically, it would be unacceptable to take no action 
    and thereby continue conditions that have caused the existing Cease and 
    Desist Order to be in effect for the Plant with periodic violations of 
    the federal Clean Water Act. In addition, the No Action Alternative was 
    rejected by the Bureau because it would not provide a means to support 
    the continued economical use of the geothermal resource in the 
    Southeast Geysers and would not assist northern California in meeting 
    its present and forecast energy demand.
        Alternative wastewater disposal locations considered in the 
    Environmental Impact Statement included injection at the Borax Lake 
    geothermal well, Audrey geothermal well or a new on-site disposal well. 
    These alternative locations are speculative and technically unproven 
    for sustaining the geothermal resource and thus would not meet the 
    objectives of the proposal. Engineers and geologists have determined 
    that the Southeast Geysers area is the best location to inject water 
    and sustain the resources, given geological conditions, topographical 
    features and environmental concerns.
        A number of alternative facility designs and routes were evaluated 
    in the Environmental Impact Statement including differences in the 
    designs for pumping water from Clear Lake, pump stations and surge 
    tanks along the pipeline route, and alternative pipeline segment 
    routes. The discussion below relates the impacts from the alternative 
    to the impacts from the preferred alternative and why those 
    alternatives were not selected.
    Alternative Facility Designs
        The Lake Diversion Pumps and Pipeline on Pier alternative differs 
    from the preferred alternative in that the pumps and pipeline to the 
    Clear Lake shore would be located on a pier instead of locating the 
    pipe underwater and the pumps on shore. This alternative would 
    temporarily increase local water turbidity and local noise from driving 
    piles for the pier and would result in an unavoidable and significant 
    alteration of the visual environment.
        The Bear Canyon Single Pump Station and One-Way Surge Tank in the 
    Geysers alternative would replace five pump stations with one large 
    pump station and require a surge tank to be located at the high point 
    of the pipeline in The Geysers. It would result in a significant noise 
    impact to residents near the larger pump station, the loss of several 
    large trees and valley oak woodland habitat which may provide habitat 
    for the Coopers's hawk and sharp-shinned hawks, and increased 
    degradation of the visual environment along a well-travelled highway.
        The By-pass Pipeline at the Plant is an alternative to discharging 
    diverted lake water into the Plant reservoir. Instead, a pipeline would 
    be constructed to channel water to the pumps for the Geysers Effluent 
    Pipeline instead of to the reservoir. This alternative offered no 
    significant environmental benefits or detriments over the preferred 
    alternative. It was rejected for engineering reasons because it would 
    create inferior Plant operating conditions and efficiencies by limiting 
    the flexibility of Plant reservoir management.
        The alternative site for the Childers Peak regulating tank would be 
    at the high point of the Geysers Effluent Pipeline between the Plant 
    and the Middletown Wastewater Treatment Plant more to the east of the 
    saddle in the Big Canyon Creek watershed. This location would require a 
    substantial cut to be made into the hillside which would introduce some 
    potential slope instability and require a greater amount of grading and 
    possibly some blasting. There would possibly be impacts of greater 
    intensity to water quality because of increased silt generation from 
    the increase in grading. Two special status plant species specimens, 
    scarlet fritillary and thread-leaved miner's lettuce, could potentially 
    be lost.
    Alternative Pipeline Routes
        Route Alternatives A-1 and A-2 would avoid placement of the 
    pipeline in existing private driveways by taking short diversions from 
    the proposed route. They would produce silt that would be conveyed into 
    the Clear Lake Outlet Channel. These routes would add 400 and 450 feet 
    respectively to the length of the proposed route. These were rejected 
    due to the siltation potential and higher construction costs.
        Route Alternative B would avoid crossing Clayton Creek on the 
    bridge by spanning the deeply incised channel upstream of the bridge 
    and crossing the large meander loop of Clayton Creek. This alternative 
    could result in a significant erosion hazard and the hazard of stream 
    erosion undermining the pipeline, potentially significant short term 
    silt deposition in Clayton Creek and potentially significant short term 
    impact to Northwestern pond 
    
    [[Page 53364]]
    turtles and the habitat of the black-shouldered kite.
        Route Alternative C would cross Highway 29 about 150 feet south of 
    a fruit and vegetable stand as proposed in the preferred alternative. 
    This route would result in no increase in negative environmental 
    impacts and would preserve several large conifers and deciduous trees 
    along the east side of the road, providing a beneficial impact on 
    visual resources. This alternative was rejected because of engineering 
    and cost benefits in implementing the preferred alternative.
        Route Alternative D would reduce the length of the pipeline by 250 
    feet by cutting across the longer turn of the existing road leading 
    down from Childers Peak Saddle. This would likely produce high erosion 
    hazards and potentially significant erosion with silt deposition 
    ultimately in Big Canyon Creek.
        Route Alternative E would reduce the need for easement acquisition 
    by continuing in a southerly direction on the Big Canyon Road to its 
    intersection with Harbin Springs Road and then proceeding northwesterly 
    on Harbin Springs Road. The preferred alternative route would cut 
    across the northern edge of a pasture. The alternative would require 
    the pipeline to be 900 feet longer than the proposed route and would be 
    located entirely within or on the shoulder of public roads, but would 
    not result in any significant change in environmental impacts. It was 
    rejected because it would result in higher construction costs with no 
    substantial environmental benefits.
        Route Alternative F would not follow a new road connecting the 
    Northern California Power Agency M-Pad but follow the Bear Canyon 
    Access Road to the Bear Canyon Power Plant, cross the creek in the fill 
    above the culvert and trend uphill to the M-pad. This route would 
    result in higher erosion hazards, potentially significant impacts on 
    runoff and water quality and would contribute to the permanent 
    cumulative loss of mixed chaparral and montane hardwood habitat of the 
    Cooper's and sharp-shinned hawk.
        Route Alternative G was a small deviation from the proposed route 
    near the end of the Geysers Effluent Pipeline to avoid construction in 
    the area of the Northern California Power Agency main gate, which 
    receives heavy vehicle traffic. The road is the Northern California 
    Power Agency's private road. The alternative route was rejected because 
    it offered no substantial environmental advantages and because the 
    construction disturbance for the preferred alternative route could be 
    accommodated.
    
    Consideration of Other Alternatives
    
        The preferred project is a preliminary plan. As the project has 
    been approved by the Lake County Sanitation District Board of 
    Directors, the phase of final engineering design will soon be started. 
    At present, the project sponsors are considering a number of design and 
    route alternatives that would represent modifications of the plan as 
    presented in the Environmental Impact Statement/Environmental Impact 
    Report. One of the primary reasons for these potential modifications is 
    to reduce mitigation costs by avoiding environmentally sensitive areas 
    altogether. These alternatives include (1) evaluation of isolation 
    valve placement; (2) relocation of the main pump station site on 
    private land within the City of Clearlake (on Robin Lane); (3) a new 
    pump station located near Highway 29 by project station 58 on private 
    land; and (4) an alternative pipeline route between the southern end of 
    the City of Clear Lake and Morgan Valley Road on private land and 
    county roads to avoid the proposed route in Lake Street which is 
    heavily constrained by cultural resources, traffic and other 
    infrastructure. All of these alternatives, if advanced to a specific 
    proposal, would require completion of supplemental review pursuant to 
    the California Environmental Quality Act and the National Environmental 
    Policy Act.
    
    Non-Environmental Factors Affecting The Decision-Making Process, 
    Rationale and Trade-Offs
    
        Non-environmental factors that entered into the Department's 
    decision-making process included the mission of contributing to the 
    research and development of alternative energy resources and a desire 
    to perform that mission while contributing to resolution of the 
    municipal wastewater treatment problems in Lake County. Cost 
    considerations were a significant consideration on the part of The Lake 
    County Sanitation District in selecting alternatives.
    
    Decision
    
        After consideration of the entire record and attachments (including 
    the conditions for right-of-way grants in the Bureau of Land 
    Management's Record of Decision) the Department has decided to provide 
    additional funding to the Lake County Sanitation District through 
    financial assistance awards for this project. The project encompasses 
    upgrades to the Southeast Regional Wastewater Treatment Plant and 
    construction of a pipeline to transport treated municipal wastewater 
    treatment plant effluent and water from Clear Lake in Lake County, 
    California, to the Southeast Geysers Geothermal Field for injection 
    into the steam field.
