PSCo entered into a long-term Renewable Energy Purchase Agreement with CCWE on December 23, 2005 under the terms of which PSCo intends to purchase the output of the Cedar Creek Wind Energy Project from CCWE. This contract was awarded pursuant to CCWE's proposal submitted in response to PSCo's 2005 Request for Proposal for Energy Resources. In that RFP, PSCo states: The addition of cost-effective renewable energy is one way to meet two of PSCo's resource acquisition objectives. One of these objectives is to procure a diverse mix of resource types that offer energy price stability and low cost energy to hedge against more volatile fossil fuel prices. Another objective is to reduce the environmental impact of new resources. As such, PSCo supports CCWE's applications to Weld County for a permit to construct and operate the Cedar Creek Wind Energy Facility, and related transmission line and interconnection facilities.

All facilities are proposed as part of the Cedar Creek Wind Energy Project (the Project) and are located within Weld County, as shown in the Project Location Map (Figure 1). Cedar Creek has prepared three separate applications requesting permits to conduct these Activities of State Interest. These applications have been filed simultaneously. Because each facility relies on the other applications to be complete, operational, and beneficial, concurrent reviews and hearings are requested. This application requests approval of the corridor necessary for the construction and operation of the 230kV transmission line associated with the overall Project. This application requesting approval of a permit to conduct an Activity of State Interest is authorized by Title 24, Section 65.1-501 of the Colorado Revised Statutes (C.R.S.) and Title 21, Article 2-10 of the Weld County Land Use Code. The Activity of State Interest involves construction, operation, and maintenance of a Major Facility of a Public Utility as defined by Weld County Land Use Code 21-3-20. Cedar Creek is a joint venture between Greenlight Energy, LLC and Babcock and Brown Power Operating Partners, LLC (Babcock and Brown). Greenlight is a national developer of large-scale wind energy projects with projects under development in 15 states, including Colorado,Wyoming, Oklahoma, New Mexico, Kansas, and North Dakota. Babcock and Brown is a global investment and advisory firm that specializes in arranging financing for, managing, and acquiring major assets such as power plants. Worldwide, Babcock and Brown has completed over 3,000 MW of renewable energy projects valued at over$3.5 billion and has over 3,000 MW of wind projects under construction or in late stage development In the U.S., Babcock and Brown has been involved in the 1 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line financing, development, and ownership of wind projects in California, Texas, Pennsylvania, New Jersey, and New Mexico. Purpose and Need The Project is proposed in response to PSCo's need for additional energy resources and desire to purchase wind energy. Electrical demand continues to increase in Colorado, largely as a result of continued growth and development along the Front Range. In December 2004, the Colorado Public Utilities Commission approved PSCo's 2003 Least-Cost Resource Plan, which included plans for a competitive solicitation to procure new energy resources. This Project will help fulfill PSCo's energy needs, as identified in the 2003 Plan. In 2004, Colorado voters passed Amendment 37, the Renewable Energy Requirement. This initiative requires that the state's largest utilities obtain a minimum of 3 percent of their electricity from renewable energy resources by 2007, 6 percent by 2011, and 10 percent by 2015. The 10 percent renewable energy standard will reduce about 3 million metric tons of power plant CO2 emissions per year by 2025, which is a reduction of 4.5 percent below business- as-usual levels. This Project will help PSCo meet obligations related to the Renewable Energy Requirement. In 2005, Cedar Creek proposed this project to PSCo in response to a Request for Proposal for Energy Resources issued by PSCo. The request states: -� The addition of cost-effective renewable energy is one way to meet two of PSCo's resource acquisition objectives. One of these objectives is to procure a diverse mix of resource types that offer energy price stability and low cost energy to hedge against more volatile fossil fuel prices. Another objective is to reduce the environmental impact of new resources. PSCo recently signed a long-term Power Purchase Agreement (PPA) with Cedar Creek to purchase the power generated from the Project. A letter confirming this agreement is attached as Appendix A. The Project will help Colorado meet a growing demand for electricity as well as increase supplies from renewable energy sources. 2 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line The area where the project is located has been identified as an Economic Empowerment Zone. Project benefits include: • Property tax payments on approximately$400 million dollars of turbines and project infrastructure • 200 part-time jobs created during construction of the facility • 14-20 long-term full-time jobs created once the facility is operational • lease and royalty payments to the 30+families with turbines on their land • option and easement payments paid to the approximate 40 landowners that would be crossed by the transmission line • increased spending at local businesses by construction workers and tourism The benefits cited above will help to provide economic stimulus to the local community and county. Site Selection Methodology The methods used to identify alternative locations for the 230kV transmission line began with delineating the Project Area. General locations for the wind energy generation site and the interconnection area were initially identified based on site requirements, engineering, and electric system planning needs.The locations of these associated project features influenced the larger area of consideration for the 230kV transmission line. A site selection process was then used to evaluate a range of resources in the area and determine alternative corridors that would minimize impacts to environmental resources and remain economically feasible. Data Acquisition Once the Project Area was defined, environmental resource data within the area was obtained and analyzed to determine which areas offer the most opportunity for siting the electric transmission line and which areas are sensitive and should be avoided. Areas were then categorized as areas of opportunity, avoidance, or exclusion on the basis of how area-specific resources might be impacted by the Project. Geographic data were obtained from the following sources: • U.S. Department of Agriculture, Natural Resource Conservation Service • U.S. Department of the Interior, Geological Survey • U.S. Department of Homeland Security, Federal Emergency Management Agency • Colorado Department of Higher Education, Office of Archaeology and Historic Preservation 5 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line • Colorado Department of Natural Resources, Division of Wildlife • Colorado Department of Transportation • Weld County Planning Department • Rocky Mountain Bird Observatory Site Evaluation The gathered data reflect existing conditions. Resource data were combined with aerial photography to provide a visual representation of the Project Area. Certain resource data were then categorized as areas of opportunity, avoidance, or exclusion. The categorized data were modeled using Geographic Information Systems (GIS) to create an Opportunity and Constraint Composite Map that identifies potential locations for siting alternatives. (See Figure 2.)Table 1 lists the resources known to exist within the Project Area and the characteristics for categorizing areas of opportunity, avoidance, or exclusion for the purpose of transmission line siting. Table 1 —Opportunity and Constraint Criteria Resource Opportunity Avoidance Exclusion Jurisdiction and Land Use Incorporated Within federally Jurisdiction County;undesignated State- cities and owned or formally owned land designated towns State-owned Land Use and Zoning Industrial,Agricultural,Open Commercial Residential Within 50 feet to 150 feet; Structures within 0.25 mile Within 50 feet of communication towers Public Schools, Within 0.25 Direct use of Parks,and mile property Recreation Areas Direct use of Within pivot irrigation Agriculture prime or State g farmland diameter Roads(interstate, Within 125 feet of state,county) Interstate/U.S./State - Residential streets Highway,or County Road Railroads Within 250 feet - - Transmission and Within 250 feet 6 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Resource Opportunity Avoidance Exclusion Distribution Lines, Gas Pipelines Geological Resources Soil Types Within highly erodible soils Biological Resources Within 100 feet of Surface Water - - lakes larger than Ya acre Wetlands _ Within boundary 100-Year Floodplains - Within boundary Within range Within 0.5 mile of Bald Eagle and foraging/ nesting sites;within concentration 0.5 mile of roost sites areas Within range Within 0.5 mile of Great Blue Heron - and foraging nesting sites;within r—^ areas 0.5 mile of roost sites Ute Ladies'-Tresses Within area of Orchid,Colorado - Direct use Butterfly Plant occurrence Cultural Resources National Register of Historic Places, _ Within 0.25 Landmarks,or mile Within 0.125 mile Monuments The following paragraphs describe the criteria for each categorical definition. Opportunity Opportunity areas include existing rights-of-way of linear facilities such as existing transmission lines, natural gas pipelines, railroads, or transportation corridors, including interstate highways, state roads, and county roads. Existing linear facilities and rights-of-way may provide suitable access for construction and maintenance and are compatible with the proposed transmission line. Avoidance Avoidance areas include sensitive areas that would likely incur impacts if adversely affected by the Project. It is preferable to avoid these areas if there are other opportunities for locating the Project. If avoidance is not possible, 7 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line minimization of impacts should be accomplished to the degree feasible through construction and operation methods or applying appropriate mitigation measures. Exclusion Exclusion areas include areas with the highest level of sensitivity, such as those areas having legal, regulatory or legislative designations or extreme physical constraints not compatible with the Project construction and/or operation. Locating a transmission line in these areas generally results in more environmental effects, higher costs, and additional regulatory approvals. Other Siting Considerations Public Involvement Public input assists in identifying the values, concerns, and interests of the community and is one of the most important factors in the energy facility siting process. Input from jurisdictions, agencies, and landowners has become a major focus in siting new utility and generation facilities. To obtain the public's input, Cedar Creek held a public open house on December 13, 2005, in Kersey, Colorado. Over 300 invitations were sent via the U.S. Postal Service to owners of property within 0.5 mile of the preliminary transmission corridors and the site boundary for the project. Other stakeholders, including municipalities and state and federal wildlife agencies, were also invited. The public open house was attended by 76 people. Representatives from Cedar Creek and its consultants, EDAW, Inc. and LoneTree & Associates, LLC, were available to provide information about the Project and answer questions. Handouts and large-format displays were available for attendees to review and discuss. The written comments that were received focused primarily on visual effects and effects of electromagnetic fields. (See Appendix B for invitations and materials provided at the public open house and written comments that were received.) Following the public open house, additional meetings were held with individual landowners to further refine the alternative transmission line routes. System Planning Utility system planners continually evaluate the performance of the electric transmission system. Once a need for a system improvement is identified, different ways of addressing that need are modeled and analyzed. The analysis of electric transmission system alternatives focuses on planning for adequate capacity to meet electric loads and high reliability. In some situations, excess capacity at one point in the transmission system may be used to address a need elsewhere in the system. However, meeting overall increased demand invariably involves new infrastructure such as the proposed Project. 8 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Economics Cedar Creek has an obligation to both its owners and customers to operate in a financially responsible manner. The relative cost of constructing, operating, and maintaining different alternatives is an important consideration when the need for new infrastructure is identified. Also important is the long-term cost of infrastructure needs. For example, an inexpensive alternative that meets near-term needs might not be the most economical alternative if several other system upgrades are needed to meet long-term demand. The proposed interconnection substation and rebuild of the interconnection transmission line meet the needs of the overall project and are economically feasible. Environment The potential effects on the environment from new transmission facilities are assessed as part of the siting process. The assessment includes collecting resource data and identifying the characteristics of the natural and human environment, identifying environmental opportunities and constraints, and assessing the relative environmental impacts of different alternatives. Specific impacts to the environment from the proposed electric transmission line are discussed in detail in later sections of this application. Engineering Cedar Creek engineers are responsible for the design of new transmission facilities and for ensuring that the Project goals and objectives are met. Input from the engineers is vital to ensure that construction and operation is reliable and safe and that the line is able to be effectively maintained. Engineering input is also important in minimizing adverse environmental effects, maintaining the Project's schedule, and meeting the Project's budget. Acquisition of Land Rights Siting new facilities requires that necessary land rights for access, construction, operation, and maintenance be obtained. These land rights for linear facilities are generally easements purchased from landowners. Cedar Creek is currently negotiating with property owners within the proposed and secondary proposed corridors to secure the appropriate land rights for construction of the transmission line. Selection of Cedar Creek Transmission Line Route Preliminary segments were selected based on the opportunity and constraint criteria described above. These preliminary segments were presented at the public open house. Based on landowner input in conjunction with further siting analysis, the proposed route and alternative were selected. A description of the proposed route and alternative is included in section 21-3-330.B.11of this application. 11 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line 12 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Areas and Activities of State Interest — Application Requirements PaN 13 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line 14 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Areas and Activities of State Interest — Application Requirements 21-3-330 Application Submittal Requirements 21-3-330.A Applicability These application submittal requirements apply to this application for a development permit for a Major Facility of a Public Utility, which is a single-circuit 230kV transmission line. 21-3-330.B Submittal Requirements 21-3-330.B.1 Map Requirements 21-3-330.B.1.a—d All map requirements including scale, as approved by Weld County, have been met. 21-3-330.B.2 Title Information 21-3-330.B.2.a Surface Property Owners The names and addresses of all owners of surface property within 500 feet of the centerline of the proposed corridor are provided in Appendix C. 21-2-330.B.2.b Access to the Project Area Right-of-way agreements include 150-foot easements purchased from landowners along the transmission alignment.

The power will be transported via the 230kV line to an interconnection point with PSCo's existing transmission system at the Rocky Mountain Energy Center (RMEC)to Green Valley 230kV line near Keenesburg, Colorado. Up to three substations will be located at the wind energy generation site near Grover, Colorado, and a switching station will be located at the interconnection site near Keenesburg. The wind generation facility and switching station are discussed in detail in separate respective 1041 permit applications submitted concurrently with this application. The proposed switching station and rebuild of a portion of the Fort St. Vrain to Green Valley 230kV line will become part of PSCo's high voltage transmission system, serving customers throughout PSCo's service territory in Colorado. The proposed transmission line and alternative locations covered in this application are shown in Figures 3 and 4A to 41. The proposed corridor is approximately one-mile in width in most locations. Cedar Creek requests a permit for placement of the 150—foot transmission line right-of-way at locations within the corridor that will be determined through final negotiations with landowners and further analysis of environmental resources. In locations where the corridor is bounded by two section lines, an additional 300 feet is included to allow for potential siting of the transmission line right-of-way on either side of the section line. The portion of the proposed corridor at Crow Creek is two miles in width to allow for flexibility in avoiding the creek and associated riparian corridor, if feasible. The transmission line structures will consist of a two-pole steel H-frame structure approximately 60 to 100 feet in height. The two poles of the H-frame structure will be 19.5 to 24 feet apart at the base and 40 to 48 feet in width at the top of the structure. At angles of greater than 5 degrees, or at other locations where engineering needs dictate, guyed three- pole steel structures will be used. Guyed H-frame structures will be used at angles of less than 5 degrees. Structures will have a weathering steel (core-ten) finish. Table 2 displays specifications for each type of transmission line structure, and Figure 6 shows graphic depictions of both structure types.

Structure Drawings Several temporary staging areas and parking facilities will be used for construction activities. The staging facilities include a construction trailer, sanitation facilities, and fencing for security and safety. Drinking water will be provided by the construction contractor in compliance with Section 30 of the Weld County Code. The Project will require a sequential construction method. The location(s) of the staging area(s) will be determined upon agreement(s) between Cedar Creek Energy and the landowner(s) along the final electric transmission line alignment. These facilities will be removed and the site returned to preconstruction conditions after construction is completed. 40 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line No permanent employees will be stationed at the transmission line. Preventive maintenance for the transmission line and substation will include routine ground patrols. The purpose of patrols is to detect equipment requiring repair or replacement. In addition to regular patrols, special patrols are conducted as needed, particularly after wind, ice, or severe lightning storms, when damage to conductors, insulators, and structures may occur. Whenever possible, ground patrols and subsequent repair activities are scheduled to minimize damage to crops or property. Maintenance may include repairing frayed or damaged conductors, inspection and repair of poles, replacing damaged and broken insulators and tightening hardware and connections. Transmission lines are sometimes damaged by storms, floods, vandalism, or accidents and may require immediate repair. Emergency maintenance involves prompt movement of crews to repair damage and replace any equipment. If property damages result from repair activities, Cedar Creek representatives will meet with the landowners to arrange for property restoration or compensation. The transmission line is proposed to be a permanent use. If the Cedar Creek wind energy facility is decommissioned in the future, it is expected that the transmission line would continue to be used to interconnect with the transmission grid. 21-3-330.B.5.f Expected Development Schedule Construction is expected to begin as early as September 2006 and last approximately 8-9 months.The overall wind energy Project will be operational in phases, beginning in June 2007 with completion by December 2007, though the transmission line should be complete by June 2007. Table 3 presents an overview of the Project Schedule. Table 3—Project Development Schedule Project Component Anticipated Start Anticipated End Date Date Design April 2006 December 2006 Engineering Construction September 2006 June 2007 Commissioning June 2007 Ready for June 2007 Indefinite Commercial Operations There are no future phases or expansions associated with the transmission line envisioned at this time. The transmission line will employ approximately 30 people during the construction phase. Construction will generally take place during one 10-12 hour shift per day during daylight trs 41 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line hours and 5 to 6 workdays per week.The peak number of workers at any one time will be approximately 40. Table 4 provides a breakdown of personnel and equipment requirements by construction activity.

Cedar Creek may also submit, if necessary, an application to the U.S. Army Corps of Engineers (USACOE) fora Nationwide Permit 12. 42 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line r 21-3-330.B.5.g Hazards and Emergency Procedures Human Hazards Given the rural nature of the land comprising the area for the transmission line, the hazards of fire, explosion or other danger to the health, safety, and welfare of employees or the general public are minimal. The greatest danger from a transmission line is direct electrical contact with conductors. Therefore, extreme caution must be exercised when operating vehicles and equipment for any purpose in close proximity to transmission lines. The proposed line is designed with overhead ground wires, and well-grounded transmission line poles protect the system from lightning. However, transmission line poles and conductors may occasionally be hit by lightning during a thunderstorm. Therefore, the area near transmission line poles and other tall objects, such as trees, should be avoided during thunderstorms. All the Project's electric facilities will be designed, constructed, operated, and maintained to meet or exceed all applicable standards of design and performance commonly used in the industry. Another perceived "hazard" is associated with electric and magnetic fields (EMF). Considerable research and study have been done to investigate potential health effects of EMF from high-voltage transmission lines on living organisms. Numerous scientific studies have been conducted to better understand if there is a connection between EMF and certain adverse health effects. The National Institute of Environmental Health Sciences included in a 1999 report that"virtually all of the laboratory evidence in animals and humans and most of the mechanistic work done in cells fail to support a causal relationship between exposure to ELF-EMF[Extremely Low Frequency Electric and Magnetic Fields] at environmental levels and changes in biological function or disease status." (National Institute of Environmental Health Sciences, 1999). Cedar Creek remains sensitive to the EMF issue and will promptly and accurately respond to inquiries with current available information. Currents and voltages that are introduced internally to the body represent a possible source of interference to cardiac pacemakers. The conclusion drawn from research and reviews of literature is that there is no risk to pacemaker wearers from electric and magnetic fields from transmission lines. Figures 7 and 8 show expected levels of EMF for the proposed 230kV single-circuit transmission line. 43 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Electric Field Cedar Creek Wind Energy _ Edge of ROW Edge c4 ROW 3 _ 5-_ I 'a w I -250 -225 -200 -175 -150 -125 -100 -75 -50 -25 0 25 50 75 100 125 150 175 200 225 250 Distance from Transmission Line(n) Figure 7.

Modeled Electric Field The Public Utilities Commission requires that public utilities weigh potential health effects and the cost of mitigating those effects by using alignments that"limit exposures (of electric and magnetic fields) to areas of concentrated population and group facilities such as schools and 44 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line hospitals," (4 C.C.R. 723-3-18(i)(2)) "or by burying transmission lines." (4 C.C.R. 723-3-18(i)(5)). This project maintains suitable distances from such areas. Environmental Hazards Enclosed containment will be provided for all trash. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials will be removed to a disposal facility authorized to accept such materials. There will be no significant amounts of hazardous materials stored in the Project Area. Construction, operation, and maintenance activities will comply with all applicable federal, state, and local laws and regulations regarding the use of hazardous substances. The only hazardous chemicals anticipated on site are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery. Hazardous materials will not be drained onto the ground or into streams or drainage areas. In its contract with the construction contractor, Cedar Creek will specify that it will hold a required pre-construction meeting with the contractor to ensure that all applicable laws and Cedar Creek's procedures will be followed. Standard Construction Mitigation Practices are attached as Appendix F. Emergency Procedures Regular patrols of the transmission line will occur. Appropriate field crews and engineering personnel are notified by telephone or radio if there is an issue and undertake the required .-� procedures to correct the problem and restore the facilities to normal operations. Natural Hazards There are no significant prevalent natural hazards that will affect or be affected by development. 21-3-330.B.5.h Name and Address of the Applicants and Fee Owners of the Property The applicant is: Cedar Creek Wind Energy, LLC Attention: Nelson S. Teague, Jr. 310 Fourth Street, N.E. Charlottesville, VA 22902 434-220-1406 See Appendix C for the fee owners of the properties proposed for the transmission line. 21-3-330.B.5.j Legal Description of the Property under Consideration The legal description of the property within the proposed transmission line corridor is included in Appendix C. 45 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line 21-3-330.B.5.k Total Acreage of the Parcel, Right-of-Way, or Corridor under Consideration Total acreage of the proposed right-of-way for the electric transmission line is approximately 1,309 acres. A survey of the alignment will be completed once all easements are secured. 21-3-330.B.5.l Existing Land Use of the Right-of-Way The proposed route is located along existing roads for approximately 14 miles of its length, and adjacent to agricultural uses, either farm or range land along the majority of the alignment (Figure 5). The proposed transmission right-of-way will typically be located a minimum of 30 feet from the existing road centerline to allow for future roadway expansion. In some locations, this will result in placement of the line unavoidably close to residences or other buildings. In areas of irrigated farming, the alignment will be placed on the perimeter of such uses to avoid pivot irrigation structures and to minimize impacts to farming operations. Illustrations of transmission structure placement along county rights-of-way are displayed in Figure 9. 21-3-330.B.5.m Existing Land Uses of All Properties Adjacent to Right-of-Way Land uses of properties adjacent to the right-of-way are displayed in Figure 5. In general adjacent land use consists of agricultural farming or grazing activities. 21-3-330.B.5.n Present Zone and Overlay Zones As mentioned above, the entire project area is zoned Agricultural. Overlay flood zones are shown in Figure 5 and include the 100-year floodplain as mapped by FEMA. If final engineering and design requires a transmission line structure to be placed within 20 feet of a floodplain, a flood hazard permit will be obtained. There are no CFR Part 77 restrictions within the Project Area. The project will not affect navigable airspace. 21-3-330.B.5.o Signatures of the Applicant and Fee Owners or Their Authorized Legal Agent Signatures of fee owners are not applicable as not all easement agreements have been obtained at this time. However, a list of easement agreements obtained to date is included as Appendix D. 21-3-330.B.6 Natural and Socioeconomic Environmental Constraints Affecting Site Selection and Construction An Opportunity and Constraint Analysis was performed as part of the preliminary site selection to identify topographic and geographic features that are compatible with construction, operation, and maintenance of the 230kV transmission line. In general, areas of sensitive natural environments, including riparian areas, water bodies, and areas of 46 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line potentially suitable habitat for threatened and endangered species or species of State concern were avoided where possible. There are no socioeconomic constraints associated with the Project. 21-3-330.B.7 Natural and Socioeconomic Environment Impacts from Construction of the Transmission Line Land Use Land use along the proposed transmission line route would be minimally impacted and would continue to include a mix of agricultural and residential uses. Minimal effects to agricultural productivity would occur as a result of this Project. Transportation Impacts The Project will not generate any daily trips during long-term operation. Regular patrols will be conducted. Approximately 30 construction workers will be employed during the course of the approximately 8-month construction period. The maximum number of construction workers at any one time will be approximately 40. No adverse effects on County roads are anticipated. Cedar Creek will work with the Weld County Public Works Department to determine the appropriate construction method for each County road crossing. All mobile construction equipment will be certified to operate on Interstate highways. Socioeconomic Impacts The Project will have a beneficial impact to the local economy. Numbers of construction contractors from the local area will be determined when a contractor is selected. Regardless of origin, it is likely that construction staff will spend money in the local area on things such as fuel, food, and other supplies. During the construction period, the local economy may see an influx of dollars and an increase in sales tax revenue. Only land surrounding the base of the structures would be removed from agricultural operations. Land between structures will remain available to farming or other operations that do not interfere with safe and reliable operation of the transmission line. It is acknowledged that there is often a perceived threat to property values from construction of transmission lines.These concerns are highest when a project is being planned or installed. Once a transmission line is established, it is much less likely to be considered a threat to property values. There are no adverse socioeconomic impacts associated with the Project. The Project will not cause any residents or businesses to be displaced. 47 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Typical Section Within Transmission Line Right-of-Way )5' 150'Transmission Line Right-of-Way �I Typical Section Along County Right-of-Way County Right-of-Way (Road or Section(he) 15t1'Transmission Line Right-of-Way Figure 9 Section Drawings 48 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Discussion of Impacts on Additional Resources, including Significant Environmentally Sensitive Factors (21-3-330.C.2) Vegetation, including Marshlands and Wetlands The majority of disturbance to vegetation from construction activities will include temporary impacts to the Conservation Reserve Program (CRP) or active agricultural lands. In addition, short-and mid-grass prairie is present within the southern portion of the area(Figure 5.) Temporarily disturbed areas such as temporary access and equipment storage areas will be reclaimed. These areas will be restored to their original condition by de-compaction where needed, re-grading, and replanting the area with a weed-free mix of species suitable to the area and approved by the Natural Resource Conservation Service (NRCS). The NRCS will be consulted regarding appropriate reclamation methods. Long-term impacts to vegetation will be minimal, consisting of approximately five square feet of disturbance at the base of each structure leg. Wetlands are not prevalent within the Project Area (Figure 10) and, where present, they will be spanned. The South Platte River and Crow Creek have the potential to support wetland or riparian areas, but impacts to these areas will be minimized by careful placement of structures. No impacts to wetlands are expected. Playa lakes are present along the proposed transmission line route. These ephemeral wetland systems provide important habitat to waterfowl and other wildlife and will not be directly impacted by structure placement, as they will be spanned. Where feasible, the transmission line will be located 0.25 mile or more away from playa lakes to minimize impacts to waterfowl and other wildlife attracted to these areas. However, given the number of playa lakes along the route, it is likely that the route will pass within 0.25 mile of at least some playa lakes. A USACOE Nationwide Permit 12 will be obtained if waterways and any associated wetlands will be impacted. This permitting process will comply with Section 404 of the Clean Water Act, which regulates impacts to"waters of the U.S." and associated wetlands. No permanent adverse impacts to drainages or associated wetlands are expected from the Project. Disturbed locations near waterways will be re-graded and re-vegetated as appropriate. Figure 10 shows waterways in the Project Area. Flood hazard permits will also be obtained if necessary. Portions of riparian vegetation at Crow Creek and the South Platte River crossings may need to be cleared within the 150-foot transmission line right-of-way(for hazard management). Within the 1-mile corridor, specific crossing and structure locations will be chosen to minimize impacts to riparian vegetation. Tree cutting would be avoided whenever feasible. Wildlife and Wildlife Habitat The following is a summary of potential impacts to wildlife from construction and operation of the 230kV transmission line. In general, impacts to wildlife would include temporary 49 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line disturbance from construction activities that would likely cause temporary avoidance of the area by some species. Long-term impacts would include minimal habitat loss at structure bases. There is no designated critical wildlife habitat within the proposed transmission line corridor. Consultation with the U.S. Fish and Wildlife Service (USFWS) and the Colorado Division of Wildlife (CDOW)was conducted to gain an understanding of wildlife issues within the proposed corridor. Coordination with these agencies will continue in order to develop the appropriate mitigation for Project impacts (Appendix F). Impacts to most mammals would be minimal due to the existing land use in the area. Mammals likely to occur within the proposed transmission line corridor include mule deer, pronghorn, coyote, red fox, swift fox, eastern spotted skunk, striped skunk, American badger, jackrabbit, cottontail rabbit, and various rodents. Impacts to mammal species from construction and operation of the transmission line are expected to be minimal and would primarily result from temporary disturbance or displacement during construction activities. It is expected that most mammal species would habituate to the presence of the transmission line. Habitat for reptile and amphibian species is severely limited within the proposed transmission line corridor. Impacts to reptiles and amphibians are expected to be minimal. Use along the proposed transmission line corridor is expected to be highest for raptor species at three locations: (1) the escarpment near the proposed wind energy facility site; (2) along Crow Creek; and (3) along the South Platte River. Raptors such as the ferruginous hawk, red-tail hawk, prairie falcon, and bald and golden eagle are present within the proposed corridor. In addition to raptors, birds likely to occur within the area include short-grass prairie species such as thrashers, thrushes, shrikes, prairie sharp-tailed grouse, vireos, warblers, wrens, grosbeaks, sparrows, towhees, blackbirds, larks, and buntings.Waterfowl and other water or wading birds are likely to occur at the South Platte River and at the ephemeral playa lakes when these areas are wet. Such species include various species of ducks, snow and Canada geese, sandhill cranes, American white pelicans, great blue herons, American cormorants, curlews, plovers, and more. In some locations along the proposed transmission line route, birds may be impacted by presence of the transmission line due to an increased risk of collision. The risk of collision is likely to be highest in locations where waterfowl or other water birds gather, or between roosting and feeding sites. Raptors are not as likely to be at risk of collision with transmission lines as are less maneuverable birds that exhibit flocking behavior(APLIC 1994). The proposed 230kV is designed with adequate conductor spacing (18 to 20 feet) to preclude electrocution of even the largest birds such as golden and bald eagles that can have wingspans of more than 7 feet. 50 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line location with the South Platte River was investigated as a mitigation measure, but was found to be cost prohibitive at $10 to$14 million per mile, versus $450,000 for an overhead river crossing. Coordination between Cedar Creek and CDOW will ensure appropriate mitigation is developed and implemented. If feasible, construction of the transmission line at the escarpment area, South Platte River, and Crow Creek will be conducted outside of raptor nesting season to minimize disturbance to nesting raptors. If this is not feasible, pre- construction nest surveys will be conducted and active nests will be avoided. Special Status Plant and Wildlife Species Data from CDOW, the Natural Diversity Information Source (NDIS), Colorado Natural Heritage Program (CNHP), and the Rocky Mountain Bird Observatory (RMBO) were used to determine those species of concern that could potentially occur within the vicinity proposed transmission line corridor. Special status species that are known to occur or have the potential to occur within Weld County include the federally and State-threatened bald eagle (Haliaeetus leucocephalus) and the federally threatened Ute ladies'-tresses orchid (Spiranthes diluvialis). CNHP data for the proposed area show occurrences of four species of special concern for the State (CDOW); the ferruginous hawk (Buteo regalis), swift fox (Vulpes vulpes), black-tailed prairie dog (Cynomys ludovicianus), and mountain plover (Charadrius montanus) (Figure 11). In addition, the proposed transmission line corridor may contain suitable nesting habitat for the State-threatened burrowing owl (Athene cunicularia). The bald eagle is known to nest and roost along the South Platte River. The nearest known bald eagle nest location is over two miles from the proposed river crossing site and over one mile from two roosting sites. Relative to other types of birds, bald eagles are not known to be at risk of collision with transmission lines, but a low increased risk of collision is acknowledged. Some temporary impacts from disturbance or displacement during construction activities are possible. As mentioned above, these risks will be mitigated, as appropriate, based on specific locations of nests and roosts in relation to the final site of the transmission line. Potential mitigation will include construction outside of bald eagle nesting season and/or preconstruction nest surveys if this is not feasible. All practicable attempts will be made to avoid construction within 0.5 mile of an active eagle nest during nesting season. Further coordination between Cedar Creek and USFWS will occur to obtain concurrence from USFWS regarding the necessary level of mitigation in order to avoid adverse effects to the bald eagle. The Ute ladies'-tresses orchid is associated with mesic habitats and prefers areas exposed to disturbances such as grazing or mowing. Mesic habitats suitable for this species are generally lacking within the proposed transmission line corridor. Mesic habitats associated with the South Platte River, Crow Creek, or playa lakes will be spanned, and impacts to this species are not expected to occur. 53 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line The northern portion of the proposed corridor is within overall range for swift fox. As with other terrestrial mammal species in the area, impacts to swift fox are expected to be minimal and primarily consist of temporary disturbance from construction activities in the area. Swift fox will likely be displaced from the vicinity during construction, but the species is expected to habituate to the presence of the transmission line. No long-term impacts to swift fox are expected. Mountain plovers nest in short grass prairies grazed by prairie dogs, bison, and cattle and in overgrazed tall grass and fallow fields. The proposed project contains some areas of suitable mountain plover habitat, and the CNHP has records of mountain plover occurrences within the northern portions of the proposed corridor(Figure 11). The construction of the transmission line is likely to result in temporary displacement of mountain plovers, but no long-term impacts are expected. Ferruginous hawks are known to occur within the northern portions of the proposed transmission line corridor, but nesting habitat is largely lacking along the proposed route. As mitigation associated with the overall Wind Energy Project, Cedar Creek will install up to 15 nest platforms in suitable locations in coordination with CDOW. Black-tailed prairie dog colonies were mapped using existing CDOW data. Further assessment and mapping of prairie dog colonies on the final alignment will occur, and colonies will be spanned when feasible. If not possible to span an entire colony, direct impact to individual burrows will be avoided. The burrowing owl is a ground-dwelling grassland species that is most often associated with prairie dog colonies, where they nest in burrows. If construction is to occur within 225 feet of a prairie dog colony during the nesting season (April through July), a preconstruction survey will be conducted in suitable habitat (prairie dog colonies) within the proposed transmission line corridor. Coordination with CDOW will ensure implementation of appropriate mitigation measures for this species. Unique areas of Geologic, Historic or Archaeological Importance A search of the National Park Service's National Register Information System (NRIS) was conducted through the State Historic Preservation Office (SHPO) on April 9, 2006, on the preliminary route to find sites listed on the National Register of Historic Places in Weld County, Colorado for the purpose of determining which sites are listed on the National Register and within the proposed right-of-way of the Project. The records search revealed 15 sites within the proposed right-of-way of the transmission line corridor. Five of these sites are either eligible for listing or have the potential to be eligible for listing. 54 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line The file search will be revised once the final alignment is selected to confirm presence of sites. In areas where sensitive historic, paleontological, or archaeological resources are known to occur, Cedar Creek will work with SHPO to conduct additional on-site preconstruction surveys or monitoring during construction in order to aid construction crews in minimizing and avoiding impacts to cultural resources. Should any previously unknown historic or prehistoric sites or artifacts be encountered during construction, all land altering activities at that location will be immediately suspended and the discovery left intact until such time that Cedar Creek, the State Historical Society, and the State Archaeologist are notified and appropriate measures taken to assure compliance with the National Historic Preservation Act and enabling legislation. 21-3-330.B.8 Long-term Effects upon Physical and Socioeconomic Development The Project will not have any adverse effects on physical or socioeconomic development of the area. 21-3-330.6.9 Mitigation of Adverse Impacts and Maximization of Positive Impacts All practical efforts will be made to restore any disturbed land to its original contour and to restore natural drainage patterns along the right-of-way. It is important to minimize any disturbances to the surrounding land during the construction because re-vegetation can be problematic in Weld County's semi-arid climate. All practical efforts will be made to re- establish native vegetation in the disturbed area. Cedar Creek's Standard Construction Mitigation Practices, included as Appendix F, addresses site reclamation of disturbed areas. Cedar Creek will continue coordination with CDOW to develop appropriate mitigation measures that are compatible with project goals and that will minimize impacts to wildlife along the proposed corridor. 21-3-330.B.10 Non-structural Alternatives There are no non-structural alternatives that would accomplish the purpose and need for the transmission line and overall Project. If the Project and the proposed transmission line are not built, PSCo would be required to seek other projects to adequately increase their energy supplies to customers and to fulfill the renewable energy mandate associated with the passing of Amendment 37. This is not an acceptable alternative as purpose and need of the Project would not be met. 21-3-330.8.11 Structural Alternatives The rapidly changing character of the area to an increasingly residential setting from a largely rural, agricultural setting created a variety of constraints for locating the 230kV electric transmission line. Each preliminary alternative brought its own set of issues and concerns 57 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line that had to be incorporated into the site selection process. The approach to site selection, therefore, was to consider all feasible alignments and ultimately select a proposed alignment that was economically sound and environmentally compatible with existing environmental conditions. The alignment also needed to be compatible with future Weld County land use plans and acceptable to the jurisdictions it crossed. Eliminated alternatives were removed from detailed analysis due to a combination of environmental and landowner concerns, as well as financial and engineering reasons. In addition to the proposed transmission line route, alternative segments are presented for consideration by Weld County. In some locations,the alternative is strong enough to be considered a secondary proposed segment that is requested for permitting along with the main proposed route. All transmission line alternatives are located entirely in Weld County, as shown in the Project Vicinity Map and Plot Plan (Figures 3 and 4-1 to 4-9). Proposed Transmission Line Route The proposed transmission line route would include approximately 72 miles of new single- circuit 230kV transmission line construction that would transmit power from the proposed Cedar Creek Wind Energy Facility near Grover to the proposed interconnection site near Keenesburg. This route would also include the final four miles as a rebuild of the Fort St. Vrain to Green Valley transmission line, as discussed in the Cedar Creek Wind Energy Project—Switching Station application. In general, the corridor width is one-mile. When the corridor is bordered by section lines, 150 feet on either side of the section lines is also included. In the vicinity of Crow Creek and the South Platte River, the corridor is greater than one mile to allow flexibility in siting at these locations in order to best take into account landowner and environmental concerns. The proposed transmission line corridor is made up of proposed segments (2, 4, 5, 6, 7, 10, 11, 13, 15, 16, 17, 18, 20) and secondary proposed segments (1, 14, 19, 21). Secondary proposed segments are included where engineering, landowner, environmental, or other criteria require additional flexibility in micro-siting of the final alignment. Permit approval of both proposed and secondary proposed corridors is requested. The southern four miles of the line leading into the switching station at the interconnection site are proposed to be a rebuild of a portion of PSCo's existing Fort St. Vrain line (included in the Cedar Creek Wind Energy Project Switching Station application). A secondary proposed corridor is also requested at this southern end of the route and is covered in this application. Overall, the proposed and secondary proposed corridors present the best opportunities to meet project goals while minimizing impacts to environmental and landowner issues. Reasons for selection of the proposed and secondary proposed corridors include: • The proposed and secondary proposed corridors meet engineering and design goals. 58 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line • The proposed and secondary proposed corridors parallel approximately 16 miles of existing transmission line rights-of-way and includes approximately 35 miles of existing roads. • The proposed and secondary proposed corridors include potential for a Platte River crossing location that minimizes impacts to riparian vegetation and habitat. • The portions of the proposed and secondary proposed corridors at the escarpment are located within areas with at least some existing impacts. Alternative Transmission Line Routes The alternative transmission line route is made up of segments 3, 8, 9, and 12. If segment 3 was utilized, this route would also follow segment 7 of the proposed route and would be approximately 67 miles long. Segment 3 exits the wind farm in a previously undisturbed portion of the escarpment that has been preliminarily identified as an area of concern for wildlife issues. The more distinct alternative segment would utilize segment 8 and would be approximately 71 miles long. This alternative runs parallel to roads for approximately 21 miles. In southern sections, the alternative runs parallel to an existing pipeline corridor, but does not run parallel to existing transmission lines and would have greater impacts to visual resources. The southern sections of the alternative route along the pipeline corridor are in proximity to numerous residences, and opposition to this and other dismissed alternatives was expressed at the public open house. 21-3-330.B.12 Air and Water Pollution Impacts Air Pollution Impacts and Control During construction, fugitive dust may be generated during periods of dry weather in areas where soil has been disturbed for installation of new poles or construction of the underground segment. Dust suppression will be performed by applying water to the area of disturbance, where necessary. After construction is completed, but before vegetation has been re- established, some minor amount of additional dust could occur. This will be monitored by Cedar Creek, and the appropriate action will be taken to control the dust and ensure that potential wind erosion is minimized. Weld County is an attainment area for all measured pollutants, including PM10. The proposed Project is an overhead electric transmission line. No air emissions will result from operation of the transmission line. No long-term adverse air quality effects will occur from the Project. Water Pollution Impacts and Control There will be no direct impacts to water quality associated with the regular operation or maintenance of the transmission line. The Project will not create runoff in excess of historic site levels and will not change existing topography or adversely affect drainage. There will be 59 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line no alteration in the pattern or intensity of surface drainage as a result of construction and operation of the transmission line. 21-3-330.6.13 Design Alternatives— Access, Landscaping, and Architecture Access to the Project will be provided by existing roads and the 150-foot-wide right-of-way along the transmission line. In some locations, new road construction may be required. Specific access through existing gates or through new locations will be agreed upon by Cedar Creek and each property owner. The access points will not require architectural or landscape treatments beyond restoring any disturbed land to its preconstruction condition. 21-3-330.B.14 Costs of New or Upgraded Services This is not applicable to this project. No new or upgraded services will be required. 21-3-330.B.15 Hydrologic, Atmospheric, Geologic, Pedologic, Biotic, Visual, and Noise Impacts Biotic and atmospheric impacts are described above. Hydrologic There will be no long-term impacts to surface water or groundwater hydrology as a result of the construction or operation of the overhead electric transmission lines. All drainages and irrigation ditches crossed by the transmission line will be spanned. This includes the South Platte River, Crow Creek, and Sanborn Draw. The Project will not impact hydrologic flow of either surface water or groundwater, nor will it affect groundwater recharge. Existing drainage patterns will be preserved. Permanent facilities would not be located in stream channels. If access roads cross stream channels, appropriately sized culverts will be installed to maintain channel flow and morphology. Minimal water use will occur during construction and operation of the Project. Water for construction purposes, including concrete foundations and dust control, will be brought in from off-site sources. No existing water rights would be impacted, and there would be no long-term use of water. Atmospheric The Project will have no long-term impact on air quality. During construction, fugitive dust may be generated during periods of dry weather in areas where soil has been disturbed for installation of new poles or construction of the underground transmission line. After construction is completed, but before vegetation has been re-established, some minor amount of additional dust could be generated. This will be monitored by Cedar Creek, and the appropriate action will be taken to control the dust and ensure that potential wind erosion is minimized. 60 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Geologic The construction and operation of the electric transmission line will not alter the geology of the Project area. The topography of the Project area is relatively flat with slopes ranging from 0 to 9 percent in the southern portion of the Project area, and slopes ranging from 0 to15 percent in the northern portion of the Project Area. Pedologic Soil erodibility factors and shrink/swell potential are displayed in Figures 12 and 13. Areas of potential subsidence do not exist in the project area based on working and abandoned mines. There are no data sources available which evaluate subsidence hazard in the Project area. The proposed transmission line corridor includes the following soil complexes: Olney—Ascalon— Platner The soils in this unit are deep, well-drained, nearly level to rolling; on plains and adjacent stream terraces. Olney soils are gently undulating soils of the plains formed in calcareous loamy alluvium. Soil texture ranges from moderately coarse to moderately fine. Ascalon soils are nearly level to gently sloping and found on plains and adjacent stream terraces. These soils are formed in calcareous loamy alluvium. Soil texture ranges from moderately coarse texture to fine. Platner soils are nearly level to gently sloping on plains and adjacent stream terraces.These soils are formed in calcareous loamy alluvium. Soil texture is moderately coarse to fine. Erodibility:The measure of erodibility is based on the soil's K factor, which indicates the susceptibility of a soil to sheet and rill erosion by water. Olney, Ascalon, and Platner soils have medium erodibility. Shrink/Swell Potential:Olney and Platner soils have a low shrink/swell potential. Ascalon soils have a low to moderate shrink/swell potential. Renohill—Terry—Shingle The soils in this unit are deep, well-drained, and nearly level to hilly; on plains and upland ridges. Renohill soils are nearly level to sloping and are on upland ridges and slightly to highly dissected plains and upland ridges.

Shingle soils are nearly level to hilly and found on dissected to highly dissected plains and upland ridges. These soils are formed in calcareous loamy or clayey residuum derived from shale. Soil texture is moderately-fine to fine. 61 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Erodibility:Renohill soils have medium to high erodibility. Terry soils have medium erodibility. Shingle soils have high erodibility. Shrink/Swell Potential:Renohill soils have a low to high shrink/swell potential.Terry soils have a low shrink/swell potential. Shingle soils have a moderate shrink/swell potential. Kim—Stoneham— Mitchell The soils in this unit are deep, well-drained, nearly level to sloping; on alluvial and colluvial fans. Kim soils are nearly level to gently undulating on foot slopes and toe slopes of fans.These soils are formed in calcareous loamy alluvium and colluvium. Soil texture is medium throughout. Stoneham soils are nearly level to gently undulating on foot slopes and toe slopes of fans. These soils are formed in calcareous loamy alluvium and colluvium. Soil texture is medium to moderately-fine. Mitchell soils are nearly level to sloping on foot slopes and toe slopes of fans. These soils are found in calcareous loamy alluvium and colluvium. Soil texture is medium throughout. Erodibility:Kim soils have high erodibility. Stoneham soils have low to medium erodibility. Mitchell soils have high erodibility. Shrink/Swell Potential:Kim and Stoneham soils have a low to moderate shrink/swell potential. Mitchell soils have a low shrink/swell potential. Arguistolls— Rock Outcrop—Ustic Torriorthents Rock outcrops occur in this unit. Soils are shallow to deep, well-drained and excessively drained, nearly level to steep soils, and on escarpment and colluvial fans. Arguistolls soils are nearly level to sloping. These soils are on moderately dissected to highly dissected shoulders and backslopes of colluvial fans. They are medium to moderately coarse textured. The rock outcrops consist of sloping, exposed areas of rock that form the vertical face of escarpments and shoulders and backslopes of colluvial fans. Ustic Torriorthents soils are gently sloping to steep. These soils are moderately dissected to highly dissect on shoulders and backslopes of colluvial fans. These soils are formed in calcareous loamy colluvium. These soils are medium to moderately coarse textured throughout. Erodibility:Arguistolls and rock outcrops are not rated for erodibility. Ustic Torriorthents are not rated for erodibility. Shrink/Swell Potential:These units do not have a shrink/swell potential rating. 62 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Valent—Vona—Osgood The soils in this unit are deep, nearly level to moderately sloping, well-drained to excessively drained sands and sandy loams. Valent soils are rolling and dune-like topography. Valent soils have a sand surface layer and underlying material. Vona soils are on the more gently sloping side slopes along the outer edges of sandhills. Vona soils have a loamy sand or sandy loam surface layer and a sandy loam subsoil. Osgood soils are in the concave, nearly level areas within the sandhills. Erodibility:Valent, Vona, and Osgood soils have low erodibility factors. Shrink/Swell Potential:Valent, Vona, and Osgood soils have low shrink/swell potential. Olney— Kim—Otero The soils in this unit are deep, nearly level to moderately sloping, well-drained sandy loams, and loans formed in mixed alluvium and eolian deposits. Olney soils have a loamy sand or sandy loam surface layer and sandy clay loam subsoil. Kim soils have a loam surface layer and loam and fine sandy loam underlying material. Otero soils have a sandy loam surface layer and fine sandy loam underlying material. Erodibility:Olney soils have low to medium erodibility. Kim soils have high erodibility. Otero soils have low erodibility. Shrink/Swell Potential:Olney soils have low to moderate shrink/swell potential. Kim and Otero soils have low shrink/swell potential. Areas of high erodibility are present within the extreme northern portion of the proposed transmission line corridor. The remainder of the transmission line routes is primarily within areas of moderate erodibility as shown in Figure 13. Overall, shrink/swell potentials are low within the Project area(Figure 14). There are no active or abandoned coal mines within the proposed right-of-way of the transmission line. Coal mines and other types of mines may increase the risk of soil subsidence. The adverse impact to Prime farmlands from the proposed Project will be minimal. The placement of the wood pole transmission line support structures will not preclude the use of farmland under the suspended transmission lines regardless of the farmland classification. The Project will not adversely affect any of the soil types within these complexes. Construction of the Project will cause some localized soil compaction and increase the potential for soil erosion. Long-term effects associated with soil compaction and erosion will be minimized or negated through strict adherence to Cedar Creek's Standard Construction Mitigation Practices (Appendix F) and the following mitigation procedures: 67 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line • Movement of construction vehicles and equipment will be limited to the construction right-of-way, existing Weld County roads, and other access routes that may need to be negotiated with landowners. • Following the completion of work, compacted soils will be loosened and leveled by scarifying, harrowing, disking, or other approved methods. • All disturbed areas will be re-graded and, where appropriate, re-seeded to provide proper drainage, stabilize soils, and prevent erosion. • Construction-phase sediment and erosion control measures will be implemented where appropriate. Visual Visual impacts of the proposed transmission line are minimized due to siting adjacent to existing transmission line corridors when feasible. Visual simulations of the proposed transmission line are under development and will be available prior to or at the time of the public hearing. Noise Audible noise from an overhead electric transmission line is produced by a phenomenon called corona. Corona is caused by the ionization of the air at the surface of the energized conductor and suspension hardware, due to very high electric-field strength. Corona is a -� function of voltage, the diameter of the conductor, and the condition of the conductor and suspension hardware. The electric field around an energized conductor is directly related to the line voltage and is the greatest at the surface. The proposed 230kV conductors for the transmission line will use a conductor of sufficient diameter to control corona effects. With 230kV overhead construction, standard conductor attachment hardware is typically adequate to control corona. Higher voltages require special low-corona hardware. Environmental noise, including electric transmission line noise, is usually measured in decibels on the audible scale (dBA), which models the sound to correspond to human perception. Table 5 shows typical dBA for various settings. The background ambient noise level varies with wind, rain, traffic, or other human activity. Because sound increase is a logarithmic calculation, adding a second circuit does not double the perceived volume of noise from a transmission line. There are generally few complaints about electric transmission line noise for levels below 50 dBA (Electric Power Research Institute, 1987). The switching station and the transmission line rebuild will meet state noise standards at the property line and edge of the right-of-way. 68 Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line r, Table 5—T •ical Ambient Noise Levels Setting Typical Ambient Noise Level Quiet suburban or rural community(remote from large 50 dBA cities and from industrial activity and trucking) Normal suburban community(not located near industrial 55 dBA activity) Urban residential community(not immediately adjacent to I 60 dBA and industrial areas) Noisy urban residential community(near relatively busy 65 dBA roads or industrial areas) Very noisy urban residential community 70 dEA Source: U.S. Environmental Protection Agency, 1974 Temporary noise impacts will occur during construction.

There will be no direct impacts to water quality associated with the regular operation or maintenance of the transmission line. Construction of the Project will not create runoff in excess of historic site levels and will not change existing topography or adversely affect drainage. There will be no alteration in the pattern or intensity of surface drainage as a result of construction and operation of the interconnection facility.

PSCo entered into a long-term Renewable Energy Purchase Agreement with CCWE on December 23, 2005 under the terms of which PSCo intends to purchase the output of the Cedar Creek Wind Energy Project from CCWE. This contract was awarded pursuant to CCWE's proposal submitted in response to PSCo's 2005 Request for Proposal for Energy Resources. In that RFP, PSCo states: The addition of cost-effective renewable energy is one way to meet two of PSCo's resource acquisition objectives. One of these objectives is to procure a diverse mix of resource types that offer energy price stability and low cost energy to hedge against more volatile fossil fuel prices. Another objective is to reduce the environmental impact of new resources. As such, PSCo supports CCWE's applications to Weld County for a permit to construct and operate the Cedar Creek Wind Energy Facility, and related transmission line and interconnection facilities.

Date: Tuesday, December 13, 2005 Time: 4:00 - 7:30 Place: Platte Valley High School Address: 901 Campbell, Kersey, CO Cedar Creek Wind Energy LLC (CCWE), a wholly owned subsidiary of GreenLight Energy, a national developer of large-scale wind energy projects, is proposing to construct a 300 megawatt (MW) wind farm in northeastern Colorado. The proposed wind farm site is to be located near the town of Grover in Weld County, Colorado. The project will interconnect to Xcel's transmission system near Keenesburg via an approximately 55- mile 230 kilovolt (kV) transmission line and switching station (See Figure X). The proposed wind farm site has one of the strongest documented wind resources in the state of Colorado according to a wind assessment initiated in 1996 by the U.S. Department of Energy (DOE). Of the 10 sites evaluated by the DOE's Utility Wind Resource Assessment Program (UWRAP), the project site had the highest documented rt average annual wind speed. Permit applications will be submitted to Weld County once the preferred route of the transmission line and switching station location are selected. The project will require a county 1041 permit for the construction of the wind farm, transmission line, and switching station. Project Area maps and other information will be on display at this public open house. Representatives of CCWE Energy will be on hand to seek your input and answer questions regarding the Project. Comment forms will also be provided. If you are unable to attend either open house, we welcome your input by telephone or email.

An invitation including the project description, location, purpose, and need for the project is enclosed with this letter. If representatives of the U.S. Fish and Wildlife Service (the Service) are unable to attend, CCWE can provide further information to the Service regarding the project upon request. Furthermore, CCWE will be in direct contact with the Service to discuss our development activities in greater detail following this public open house. The project is located entirely within Weld County and includes a proposed wind farm near Grover, meteorological equipment, a 230kV transmission line, substation, and a switching station to interconnect to Public Service of Colorado's existing transmission system near Keenesburg. The Pawnee National Grasslands are located to the south, west, and east of the northern portion of the proposed project. Preliminary research by EDAW, Inc. (EDAW), our consultant, has determined federally listed and candidate species which have the potential to occur in the area include: •Bald eagle(Haliaeetus leucocephalus) •Piping plover(Charadrius melodus) •Preble's meadow jumping mouse (Zapus hudsonius preblei) •Colorado butterfly plant(Gaura neomexicana spp. coloradensis) •Ute-ladies tresses orchid(Spiranthes diluvialis) •Yellow-billed cuckoo (Coccyzus americanus) The Pawnee National Grasslands provide habitat for a number of resident and migratory avian species. The project area likely contains habitat for the state threatened burrowing owl (Speotyto cunicularia), the black-tailed prairie dog (Cynomys ludovicianus), golden eagles (Aquila chrysaetos), mountain plover (Charadrius montanus) and the ferruginous hawk (Buteo regalis). The Colorado Division of Wildlife is also being consulted to acquire information regarding state species and habitats of concern. If wetlands are identified within the project area, the Army Corps of Engineers (Corps) would be consulted to determine if wetlands are jurisdictional "waters of the U.S.". If"waters of the U.S." are identified by the Corps and are to be impacted by the proposed project, CCWE would ensure the project complies with Section 404 of the Clean Water Act. Additional information on federal status species and sensitive habitat types which may occur within the project area is requested at this time. If a federally listed species could potentially be impacted, further consultation with the Service would be initiated once further analysis is completed. Please feel free to contact EDAW or myself with questions or comments. We hope to see you on December 13. Sincerely, ifelana3tres, - Nelson S.

Purpose and Need The Cedar Creek Wind Energy, LLC (CCWE) Project is proposed in response to Public Service of Colorado's (Public Service) need for additional energy resources and desire to purchase wind energy. Electrical demand continues to increase in Colorado, largely as a result of continued Amendment 37 growth and development along the front range. In December 2004, the Colorado Public Colorado voters passed Utilities Commission approved Public Service's 2003 Least-Cost Resource Plan, which included Ammendment 37, the Renewable plans for a competitive solicitation to procure new energy resources. Energy Requirement in 2004. In 2005, CCWE proposed this project to Public Service in response to Public Service's February The CCWE Project will help meet 2005 Request for Proposals for Energy Resources. Public Service notes in that request for obligations related to this law proposal: by providing enough energy annually to power 85,000 The addition of cost-effective renewable energy is one way to meet two of PSCo's resource homes. acquisition objectives. One of these objectives is to procure a diverse mix of resource types that offer energy price stability and low cost energy to hedge against more volatile fossil fuel prices. Another objective is to reduce the environmental impact of new resources. Colorado voters passed Ammendment 37, the Renewable Energy Requirement in 2004. This initiative requires the state's largest utilities to obtain a minimum of 3 percent of their electricity from renewable energy resources by 2007, 6 percent by 2011, and 10 percent by 2015. The 10 percent renewable energy standard will reduce about 3 million metric tons (MMT) of power plant C02 emissions per year by 2025—a reduction of 4.5 percent below business-as-usual levels. The CCWE Project will help Public Service meet obligations related to the Renewable Energy Requirement. Benefits Economic Benefits Wind Power Benefits The proposed wind farm is sited within an area established by the State of Colorado as an Economic Empowerment Zone, within which economic development is encouraged. The Project • Renewable will represent an investment of approximately $400 million in Weld County, and generate •No emissions of SOx, NOx, property tax revenues of approximately $3.5 million. carbon dioxide, mercury, The Project will employ approximately 200 people during the construction phase and radiation approximately 10 full-time equivalent positions throughout its operating life. • No smog and acid rain • No waste storage issues During construction and operation, the Project will stimulate the local economy via purchase of goods and services. • Cost competitive, proven technology Environmental Benefits • Does not consume water The Project will provide clean, efficient renewable energy to assist Public Service in meeting •Stable pricing the Renewable Energy Requirement. • Domestic energy source, Since wind energy is a clean energy source which results in no air emissions, this electricity energy security will be generated without emissions of C02, NOx, or 502. When compared to fossil-fuel based generation, this Project represents the removal of more than 900,000 tons of such pollutants per year from the environment. December 2005 Punta. Nag & Nests Energy System Benefits The Project will provide cost effective, clean renewable energy to help meet the growing electrical demand in Colorado. Public Service has identified wind energy as one of its preferred technologies in a diverse resource mix to meet future energy needs. The Project will generate enough electricity annually to power 85,000 homes. Colorado Wind Power at 50m Above the Surface r•+ rl•....

CCWE's representative will evaluate each property on which easement rights may need to be acquired to determine the appropriate amount of compensation for the rights. In the , event that a complicated appraisal problem exists, or if statutory requirements in the Local E jurisdiction dictate, CCWE's representative will complete an appraisal to determine the value -4- of the rights. CCWE will make an offer to the owner to obtain the necessary property rights. WpOrtits 2 - Negotiations ' '„ The CCWE right-of-way representative will begin the negotiating process by presenting the sit ' ++. k required legal document(s) to the property owner. The representative also will provide maps 3` of the Line route or site, maps showing the Landowner's parcel, and an offer of compensation for the easement or purchase. The landowner will be allowed a reasonable amount of time `' _,ra.:,;-: to consider the offer and to present material to CCWE that the owner believes is relevant to deciding the value of the property. 3 - Survey permission A right-of-way representative will contact each property owner or his or her representative to inform them of the Project. The right-of-way representative will describe the need for the transmission line and how it may affect the property. CCWE's survey crews then will enter the r ? property to complete preliminary survey work. 4 - Negotiated settlement In nearly alt cases, CCWE's representatives are able to work with the landowners to address their concerns and to arrive at negotiated settlements that are fair and acceptable to all parties. In some cases, however, negotiated settlements are not possible, and the landowners may choose to have independent third parties determine the value for the rights. This is accomplished through the exercise of CCWE's right of eminent domain. The process of exercising the right of eminent domain is called condemnation. 5 - Acquisition by eminent domain (condemnation) In any project that requires easements for power line construction, the goal is to offer fair and equitable compensation to landowners. CCWE may initiate condemnation proceedings only • when good faith and reasonable efforts to negotiate an agreement have failed. cw.re.r 6 - Document preparation CCWE will prepare all of the documents required to complete each transaction. Some of the documents that may be required include an option agreement, easement, purchase agreement or contract, deed, license, subordination agreement, and clearing and construction notice. December 2005 7 - Survey staking After the power line design is completed, a survey crew will stake the line. This means that PDT the survey crew wilt determine the location for each structure and mark the places with inn;sni:null Liu:LU_ surveyor's stakes. The right-of-way representative can then show the landowners exactly where the structure(s) will be located on their property. 8 - The construction process Once the easement or land rights have been acquired and prior to construction, CCWE's right- of-way representative will contact the property owner and discuss the construction schedule. During construction the following may be required: iiiAda T = € • Temporary removal or relocation of certain fences • Installation of temporary gates (or permanent gates at landowner's request) • Early harvest of crops where possible • Removal or relocation of equipment and livestock from the right-of-way • Restoration and cleanup The right-of-way representative will contact each property owner after construction is completed to see if any damage has occurred as a result of CCWE's activities If damage has occurred to crops, fences, or the property, CCWE will reimburse the landowner fairly for the damages. In some cases CCWE may engage an outside contractor to restore the damaged property as near as possible to its original condition. Typical H-frame transmission right-of-way needs: • Typical structure height: 60-95 feet • Typical right-of-way width: 150 feet (115 feet adjacent to road right-of-way) • Typical span length: 400-1000 feet • Abstract of title Width:25' width:no'--_ 4—s .,. •",:i cani n:'='w r l5'rransmissi.n tine ai.ht-.r-war 1=0 RonaNl:�bpol-Wny 1 T,ansmissi.n Line i.ht-.f-Wa --. r Wood H-Frame Adjacent to Road Right-of-Way Single Steel Pole Adjacent to Road Right-of-Way r rrr fj. IN`N ��JtThc Cedar Creek Wind Energy, LLC (CCWE), a wholly owned subsidiary of Greenlight Energy, Inc., a national developer of Large-scale wind energy projects, is proposing to construct a 300 megawatt (MW) wind farm in northeastern Colorado. The project is to be located near the town of Grover in Weld County, Colorado. j • The Project will consist of up to 300 individual three-bladed wind turbine generators, mounted on tubular steel towers approximately 265 feet (80 meters) high with rotor diameters of up to 263 feet (93 meters). The exact number of towers will depend upon the specific wind turbine manufacturer selected for the Project, since commercially available wind turbines range in size from 1.0 to 2.3 MW. Thus, for the total proposed Project capacity of 300 MW, the overall Project will include between 131 (using 2.3 MW wind turbines) to 300 (using 1.0 MW wind turbines) individual wind turbine generators and towers. The towers will be erected in rows • generally following higher topography on the site and spaced approximately 750 feet apart • and 2,500 feet from row to row. The Project will minimize the need for new permanent site roads through the utilization of existing access roads and County roads wherever possible. The roads would generally follow the rows of wind turbine generators, and have a compacted gravel surface approximately 15 ^., feet wide with shoulders of approximately an additional 10 feet wide.

A 34.5 kV electrical collection system will gather the electricity from each wind turbine generator and route it to a Project substation on the Project Area. Portions of this collection system will be installed underground, typically Located adjacent to the access roads and along • ' "4 y the rows of the wind turbine generators. Portions of this collection system will be installed aboveground, tying the rows of turbines together and forming a "backbone" of the electrical ' collection system. The electrical collection system will terminate at a Project substation. The Project Substation 00* +A.. - will include breakers, switching and metering equipment, and a 34.5/230kV step-up _ transformer which will increase the voltage from the 34.5kV collection system to the 230 kV interconnection transmission system. The Project Substation will be approximately 3 acres and wilt be fenced to control access to high voltage electrical equipment. A permanent operation and maintenance ("O&M") building will be constructed on the Project Area. It would consist of approximately 5,000 square feet of enclosed space, including offices, spare parts storage, kitchen, restrooms, and a maintenance shop area. The overall area of the building and parking would be approximately 2 acres. The proposed transmission line The proposed new transmission line will be constructed to meet the requirements of the will be constructed primarily National Electrical Safety Code for heavy loading, heavy winds, and icing so that a safety of wood H-frame structures margin is maintained between the wires and the ground. The transmission line will also be ranging between 60 and 95 feet in height. protected from lightning by an overhead shield wire placed at the top of the steel poles and grounded at each structure location. The transmission line wilt be constructed in an easement generally 150 feet in width. Easements will be purchased from landowners. Construction of the transmission line is expected to occur in 2007 and take 6-9 months to complete. A new 230 kV switching station will be built near the existing F : 8 — Rocky Mountain Energy Center site. The site will be selected - -a.-- " based on other required interconnections and land availability. / + Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line Appendix F Mitigation Practices Cedar Creek Wind Energy Project Weld County 1041 Permit Application Electric Transmission Line THIS PAGE INTENTIONALLY LEFT BLANK Cedar Creek Wind Energy Project Construction Practices and Mitigation Measures The following measures will be implemented by Cedar Creek Wind Energy, LLC (Cedar Creek) for mitigating impacts from the proposed Cedar Creek Energy Project. 1. Construction of the overhead transmission line will require minimal clearing of the chosen right-of-way (ROW). Reclamation of temporarily disturbed areas around the transmission structures, including roads not needed for maintenance, will be completed by regrading, discing, mulching, fertilizing, and reseeding with a native seed mixture appropriate to the type of vegetation disturbed and approved by the Natural Resources Conservation Service (NRCS). Within the South Platte River and Crow Creek corridor, some removal of riparian vegetation such as cottonwoods and willows will likely be necessary. Existing access will be used whenever feasible to minimize disturbance to vegetation resources. 2. In the entire Project Area, contractors will exercise care to preserve the natural landscape and will conduct construction operations so as to prevent any unnecessary destruction, scarring or defacing of the natural surroundings in the vicinity of the work. Except where clearing is required from permanent works, approved construction roads, or excavation operations, vegetation will be preserved and will be protected from damage by construction operations and equipment. 3. When construction is complete, all storage and construction materials and debris will be removed from the site. 4. All areas of potential soil disturbance within the Project Area will be surveyed for noxious weeds before construction begins.Noxious weeds will be mechanically controlled in all surface disturbed areas. If herbicides are needed to control noxious weeds, they will be applied by a licensed contractor. Equipment will be washed at a commercial facility prior to construction and on-site during construction if weeds are found within or adjacent to the project area. A Cedar Creek contractor will be responsible for monitoring, treating, and documenting noxious weeds throughout the life of the project. A weed management plan will be developed that discusses both general and species-specific weed control methods. 5. Cedar Creek will limit construction activities and equipment movement to access routes, the right-of-way or construction easement to minimize damage to residential yards, grazing land, crops, orchards, and property. Cedar Creek will coordinate with landowners to avoid impacting the normal function of irrigation devices during Project construction and operation. 6. When weather and ground conditions permit, Cedar Creek will obliterate all fraN construction-caused deep ruts that are hazardous to farming operations and to the movement of equipment. Such ruts will be leveled, filled and graded, or otherwise eliminated in an approved manner. Ruts, scars and compacted soils in hay meadow, alfalfa fields, pasture, and cultivated productive lands will have the soil loosened and leveled by scarifying, harrowing, discing, or other approved methods. Damage to ditches, tile drains, terraces, roads, and other features of the land will be corrected. At the end of each construction season and before final acceptance of the work in these agricultural areas, all ruts will be obliterated, and all trails and areas that are hard-packed as a result of construction operations will be loosened and leveled. The land and facilities will be restored as nearly as practicable to the original condition. 7. Standard mitigation practices will be required to avoid impacts to water resources. These will include those listed under the soil erosion plan and under a hazardous waste management plan to minimize the risk of contaminating water resources during project construction. Construction activities will be performed by methods that prevent entrance or accidental spillage of solid matter, contaminants, debris, and other objectionable pollutants and wastes into flowing streams or dry water courses, lakes, and underground water sources. Such pollutants and wastes include, but are not restricted to refuse, garbage, cement, sanitary waste, industrial waste, , oil and other petroleum products, aggregate processing tailings, mineral salts, and thermal pollution. 8. Dewatering work for transmission line trenching, structure foundations, or earthwork operations adjacent to, or encroaching on,jusrisdictional streams or watercourses will not be performed without prior approval from appropriate state or federal agencies. 9. An erosion control/stormwater management plan will be developed and implemented to prevent sediment input to the South Platte River and all other drainages within the overall Project Area. The plan will be designed to meet the requirements of the Colorado Department of Public Health& Environment's Construction Stormwater Discharge Permit. Measures associated with this plan will be implemented during project construction and any future maintenance activities associated with the wind energy facility,transmission line, and switching station. Waste waters from construction operations will be handled in accordance with Corps of Engineers Nationwide Permit 12 and Colorado Department of Public Health and Environment Water Quality Control Division permit discharge requirements. Erosion mitigation measures will include the use of one or more devices such as temporary berms, slope drains, diversion mounds, or sedimentation basins, as appropriate. Silt fence will be used to prevent sediment from entering wetlands or open water. Temporary drainage control will also be implemented as appropriate to aid in controlling erosion and sedimentation. 10. Wetlands, floodplains rivers, streams, and lakes will be avoided whenever feasible. The location, alignment, and grade of construction roads will minimize impacts to wetland,riparian, and aquatic resources. Impacts to wetlands, including playa lakes at the wind energy facility site, are not expected to occur. If construction must occur in wetlands, it will take place during winter months in order to minimize impacts to soils ^ and vegetation and appropriate permits as outlined under Section 404 of the Clean Water Act will be obtained. 11. The proposed transmission line will cross the South Platte River. Since the South Platte River is a jurisdictional "waters of the U.S."as designated by the Army Corps of Engineers, consultation with this entity and notification of the project will be required to avoid impacts or to implement appropriate mitigation. 12. Equipment and vehicles will avoid riparian areas on the right-of-way during construction and operation activities where possible and minimize impacts by using existing access points. Existing bridges or fords will be used to access the right-of-way on either side of riparian areas. 13. Cedar Creek has identified and plans to perform a series of studies aimed at identifying existing wildlife resources on the wind farm site and along the transmission line corridor. These studies have been designed in consultation with CDOW and USFWS. Studies that are currently being conducted or that will be conducted include: • Raptor Nest Surveys—Wind Energy Facility Site • Sharp-tailed Grouse Lek Surveys—Wind Energy Facility Site • Breeding Songbird Surveys—Wind Energy Facility Site • Mountain Plover Surveys—Wind Energy Facility Site • Reptile and Amphibian Surveys - Wind Energy Facility Site • Sensitive Habitat Assessment —Wind Energy Facility Site and Transmission Line Route • Wetland Assessment—Wind Energy Facility Site and Transmission Line Route • Bat Use Surveys—Wind Energy Facility Site • Swift Fox Den Surveys—Wind Energy Facility Site Upon completion of certain key preconstruction surveys identified above, Cedar Creek will investigate and, to the extent necessary, propose a variety of potential site-specific and species specific mitigation measures to mitigate potential impacts to wildlife. These measures may include actions such as: • Detailed transmission line preconstruction habitat assessment and raptor nest surveys; • Setbacks of either construction-related activities or permanent facilities (i.e. roads, towers) from sensitive areas; • Limiting time of construction to exclude breeding or nesting seasons; • Additional studies during construction and/or post operations to determine impacts; • Special design features aimed at minimizing avian impacts(i.e. perch deterrents, flight diverters, conductor spacing, etc); �� • Creation of new habitat features (i.e. raptor nesting platforms); and • Creation of habitat conservation areas to offset potential impacts; • Avoidance of impact to sensitive habitats and areas such as wetlands and black- tailed prairie dog colonies when feasible. CCWE will work cooperatively with CDOW and USFWS to review potential impacts and select appropriate mitigation strategies given the nature of the proposed project, potential impacts, and likely effectiveness and feasibility of mitigation measures. 14. A cultural resource file search of the State Historic Preservation Office (SHPO) database has been conducted for the project area. In areas where sensitive historic, paleontological, or archeological resources are known to occur Cedar Creek will work with SHPO to conduct additional on-site preconstruction surveys or monitoring during construction in order to aid construction crews in minimizing and avoiding impacts to cultural resources. 15. Fire-fighting equipment will be located in vehicles and the O&M facility. If fires cannot be extinguished with resources on-site, the landowner, sheriff, and local fire department will be advised. Fire deterrents within the wind farm will include access roads, which may serve as fire breaks and regular clearing of vegetation from areas around transformers, riser poles, and buildings. Annual reports detailing fire and fire suppression efforts will be recorded by O&M staff and provided to Cedar Creek annually. 16. An Emergency Response Plan will be established for the project to ensure employee safety for emergencies such as personnel injury, fires, explosions, and other scenarios where project evacuation will be required. The Emergency Response Plan will cover project employees, site visitors, and onsite contractors, and will be administered by the project operations manager or designee. Part of this plan will include prior coordination with local emergency response agencies to plan for proper communication and response to on-site emergencies. Hello
