Below are general legal descriptions of the proposed electric transmission rights of way and substation locations. 230,000 Volt Electric Transmission Line From Public Service's Rifle Substation to Cogeneration Technology, and Development Company's 11 Substation/Plant Beginning at Public Service's existing Rifle Substation located in the Southwest Corner of Section 16, Township 6 South, Range 92 West of the 6th Principal Meridian, thence Southwesterly and parallel to the South side of the existing Cameo -Rifle 230,000 volt electric transmission across SEASE4 of Section 17; the NINE* and the NNW of Section 20; the N2 of Section 19 11 all in Township 6 South, Range 92 West, and the Nz of Section 24, Township 6 South, Range 93 West to a point near the North-South centerline of said Section 24; thence northwesterly to the Cogeneration Technology and Development Company Substation located approximately 1700 feet East and 500 feet South of the Northwest Corner of said Section 24. 1 1 1 1 I/ I 11 1 1 11 -3- EXHIBIT B REQUIREMENT 1. PLANS AND SPECIFICATIONS -4- • r1 1 1 1 1 1 1 1 1 1 1 1 1 EXHIBIT B REQUIREMENT 1. PLANS AND SPECIFICATIONS The transmission line will be a single circuit 230,000 volt line from the Cogeneration Technology and Development Company (CTDC) Substation to Public Service's Rifle Substation. A separate line interconnecting the Rifle Substation is necessary to insure the reliability of the major power system. By constructing a separate line on separate structures, electrical faults, outages or maintenance can be corrected without interrupting service to residences and businesses relying on the main power transmission system. The transmission line will be constructed on wood poles 75.0 feet southerly of the existing line owned by Public Service as shown on Exhibit B1. The in-line structures will be H -Frames and the angle structures will consist of three (3) wood poles guyed for additional support. These structures are illustrated on Exhibits 62 and B3. At the existing Public Service Rifle Substation additional facilities must be installed to terminate the new transmission line. This will include extending the existing bus approximately 100 feet to the south, installing a line dead-end structure, and the associated circuit breakers and switches. The existing chain link fence will be extended to encompass the new facilities. Please refer to Exhibit B-4. The total estimated cost for this project is '1,250,000. -5- limp aim, slur aum in; (II* lei' smolt -mit m aim elm INN 11•11 Ile cin 1181NXS 1 1 1 co N to mm x r si z0 m • • 1 1 r 1 1 1 1 s 1 1 1 1 1 s • NOT TO SCALE 230,000 VOLT WOOD H -FRAME SUSPENSION TANGENT STRUCTURE —7— 651—Oss TO 85'-0" EXHIBIT B2 751-0' TO 851-0" • • 9 A NOT TO SCALE 230,000 VOLT DEAD-END AND ANGLE STRUCTURE - 8 - /7 EXHIBIT B3 RIE SUBSTATIV $ vr 280 610' LEGEND EXISTING EQUIPMENT AREA NEW EQUIPMENT AREA Nfin _9_ EXHIBIT B4 0 W 100 1 r • 1 1 1 1 1 1 1 1 EXHIBIT C REQUIREMENT 2. 1 LETTERS OF APPROVAL a 1 1 1 1 1 1 1 1 -10- EXHIBIT C 11 REQUIREMENT 2. LETTERS OF APPROVAL 11 The proposed electric transmission and substation system will have no need for sewer, water, or gas service. Therefore there will be no need for the extension of any of these services. Telephone service may be provided at the substation sites when, and if, service is extended and available. The proposed facilities will not involve the construction or upgrading of any roadway or road system which requires public or county maintenance. Public Service will coordinate the crossing of other utilities by the proposed electric transmission system prior to construction. Mountain Bell 11 and all participants in the proposed common utility corridor will be contacted to ensure the compatibility of all systems. Subject to the granting of the Special Use Permit herein applied for, Public Service will acquire the subsequent crossing permits. Also subject to the granting of the Special Use Permit herein applied for, Public Service will initiate negotiations to acquire the required easements. Should negotiations through normal procedures be unsuccessful, Public Service has the power of eminent domain to secure the required land rights (CRS 1973:38-5-105). 11 As a public utility, Public Service is well aware of the coordination required with other utility facilities and will design and construct the 11 proposed electric transmission line and substation system accordingly. All of the electric facilities have been designed to provide the most economical and reliable service and to augment Public Service's bulk power 11 system. Cogeneration Technology and Development Company will incur the cost for the entire system. 1 1. I/ 1 1 11 -11- 1 • • 1 1 1 t 1 1 1 EXHIBIT D jREQUIREMENT 3.

IMPACT STATEMENT ON THE PROPOSED USE 11 5.03.07 INDUSTRIAL OPERATIONS 5.03.07(1) Impact Statement Location and Scope The federal Public Utility Regulatory Policy Act of 1978 provides that electric utilities must purchase electric energy made available by qualified cogeneration and small power producers. I/ The Cogeneration Technology Development Corporation project is a qualified cogeneration and therefore must be connected into the utility system. Public Service has contracted for the purchase of this electric energy. The 80 megawatts to be connected into the electric transmission system must be done in such a manner as not to jeopardize the stability of the existing bulk power transmission systems. As a result, the proposed electric transmission line and substation system has been designed to become a part of the electric system which can be isolated during faults, outages or maintenance at either the CTDC Substation or on the existing Public Service system. The project will consist of a separate 230,000 volt electric transmission line between the CTDC Substation and Public Service's Rifle Substation. The specific description and location of the proposed facility are included in the response to Requirements 1 and 3 of this Special Use Application. Design The design specifications of the proposed facilities are included in the response to Requirement 1 of this Special Use Permit Application. Refer to Exhibit B and Exhibit D. Construction Schedule I/ Construction of the facilities required for the proposed transmission line and substation system is scheduled to be completed prior to April 1987. In order to meet this in-service date, the following activities are scheduled: 1 Transmission Line Survey Complete Transmission Line Construction January - February 1987 I/ Rifle Substation Construction November 1986 - February 1987 Operational Characteristics All Public Service facilities are designed, constructed, and operated to meet or exceed all applicable standards of design and performance 1 -15- 11 set forth in the National Electric Safety Code. The transmission lines are patrolled periodically to detect wear or any damaged II equipment. Periodic patrol and maintenance of the substations requires two employees once a week on the average. All Public Service personnel receive safety training for emergency situations. 1 5.03.07(1)(a) Effect on Use of Water The proposed project will have no significant adverse effects on II the existing lawful use of water through depletion or pollution of surface run-off, stream flow or groundwater. I The proposed electric transmission line and substation system has no water requirements. Minimal quantities will be consumed by construction workers and may be required for dust suppression II during construction. Pollution of the surface run-off, stream flow or groundwater by erosion will be prevented substantially by limiting access to existing roads and trails. Where soil disturbances occur at the structure locations and substation I sites, the disturbance will be kept to a minimum and revegetated (Refer to Section 5.03.07(5)). II 5.03.07(1)(b) Effect on Adjacent Land The proposed project will have no significant adverse effects on adjacent land through generation of vapor, dust, smoke, noise, II glare or vibration, or other emanations. The generation of dust will be a temporary condition during construction and will be limited by keeping soil disturbances to a minimum and timely II revegetation of disturbed areas. The generation of noise during construction, operation, and maintenance of the proposed facilities will temporarily disturb the area wildlife. The II degree of this disturbance will be insignificant when compared to the activities resulting from the other uses permitted adjacent to all of our facilities. The generation of glare by the proposed facilities will be reduced by the use of non -specular 11 conductors, dull galvanized steel, and limited use of paints or stains. II5.03.07(1)(c) Effect on Wildlife and Domestic Animals The proposed project will have no significant adverse effects on the wildlife and domestic animals through creation of hazardous 11 attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. 1/ Public Service has participated in, and co-authored, several studies concerned with the design of transmission structures to prevent the electrocution of raptors and migratory birds, and to I/ enhance their nesting habitats. The findings of these studies will be implemented in the design and construction of the transmission system. 1 �-16- • • 5.03.07(2) Traffic I A temporary impact on the road system will result from construction activities. This temporary affect will not be of sufficient magnitude to require any changes to the County's existing maintenance program. II The truck and automobile traffic to and from the proposed facilities for Public Service's operation and maintenance will not create hazards or nuisance. Transmission line patrols are done from the air. Monthly surface patrols will be limited to maintenance activities. No II employees will be permanently located at the substation facilities and periodic patrol and routine maintenance will require two employees once a week on the average. 1 5.03.07(3) Safe Distances All Public Service facilities are designed and constructed to meet or II exceed all applicable standards of design and performance set forth in the National Electric Safety Code. I The right-of-way requirements are designed to provide sufficient distances to separate the proposed transmission lines from abutting properties. Vertical clearances, established by the National Electric II Safety Code, are also maintained at all crossings of transportation facilities; i.e., railroads, interstate highways, state highways, county roads, and any other area where vehicular use may occur. II Public Service installs automatic and instantaneous breaker devices on both distribution feeders and transmission lines. The proposed substation will be equipped with automatic switching gear and II supervisory equipment which protect the system and maintain a high level of reliability. 5.03.07(4) Additional Information IIThis section reserved for submission of response to additional information if requested by the County Commissioners. 1 5.03.07(5) Rehabilitation II 5.03.07(5)(a) Rehabilitation Plan When the construction activities are complete, all crates, boxes, bands, reels, lagging, wrapping, wire pieces, and other material 11 or equipment waste of every kind will be cleaned up and properly disposed of. All light material which might be spread by the wind will be cleaned up and disposed of on a daily basis. 11 Vegetation and soil disturbances will be minimized and revegetation will be initiated after construction of the I/ transmission line is completed. The following specification was prepared with assistance from the Garfield County Extension Office and will be implemented to reclaim all disturbed areas: -17- • • 1. Lightly scarify the disturbed area with a rake or a disc set straight, depending on the size of the disturbance, topography and access. 2. Fertilizer shall be surface applied evenly at the rate of 100 pounds (bulk)/acre (33-0-0) and 100 pounds (bulk)/acre (18-46-0). 3. The following seed mix shall be broadcast uniformly at the rate of 30 pounds pure live seed/acre and lightly raked into the soil. Crested Wheatgrass Intermediate Wheatgrass Russian Wild Rye Manchar Smooth Brome 20% proportion 35% proportion 10% proportion 35% proportion by weight by weight by weight by weight 4. Native hay mulch shall be evenly applied by a straw blower at the rate of 1000 pounds/acre and crimped into the soil with a shovel or by lightly discing with the disc set straight. 5.03.07(5)(b) Security for Execution of Rehabilitation Plan Security for the execution of the Rehabilitation Plan will be provided if required. 5.03.08 INDUSTRIAL PERFORMANCE STANDARDS 5.03.08(1) Volume of Sound Generated The proposed electric transmission and substation system will be so operated that the volume of sound inherently and recurrently generated will not exceed eighty (80) decibels at any point on any boundary line of the property on which the use is located. The sound generated by an electric transmission line is minimal directly beneath the conductors. Wet and foggy weather provides a more favorable condition for the sound that is generated and a crackling noise is more perceptible. However, the ambient noise level is usually higher during these conditions also. The maximum sound levels expected on this right-of-way during worst conditions should not exceed 50dbA. 5.03.08(2) Vibration Generated The proposed transmission and substation system will be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point on any boundary line of the property on which the transmission line or substation is located. -18- • • 5.03.08(3) Emissions of Smoke and Particulate Matter There is no combustion or emission of any pollutants associated with the operation of the proposed electric transmission and substation system. Minimal quantities of dust and vehicle exhaust will result during construction. These will be insignificant and of short duration. There will be no measurable effect on air quality. The proposed transmission and substation system will be operated to 11 comply with all federal, state, and county air quality laws, regulations, and standards. 5.03.08(4) Emissions of Heat, Glare, Radiation, and Fumes The emissions of heat, glare, radiation, and fumes from the operation of the proposed electric transmission system will not interfere with the existing use of adjoining property, and will not cause a public nuisance or hazard. 5.03.08(5) Storage Area, Salvage Yard, Sanitary Land Fill, and Mineral Waste Disposal Sites The construction of the proposed transmission line and substation system may require materials to be staged at the Rifle Substation and at the CTDC site. When construction is complete the sites will be rehabilitated as indicated in the Rehabilitation Plan. 5.03.08(5)(a) Compliance with National Fire Code Storage of flammable, or explosive solids, or gasses will be in accordance with accepted standards and laws and will comply with the National Fire Code. 1 5.03.08(5)(b) Storage Area Enclosure At the discretion of the County Commissioners, all outdoor 11 storage facilities for fuel, raw materials and products will be enclosed by a fence or wall adequate to conceal such facilities from adjacent property. 11 5.03.08(5)(c) Material Storage 11 No material or waste will be deposited upon the property in such a form or manner that they may be transferred off the property by any reasonably foreseeable natural causes or forces. 5.03.08(5)(d) Health Regulations All materials or waste which might constitute a fire hazard or I/ which may be edible by or otherwise be attractive to rodents or insects will be stored outdoors in accordance with applicable State Board of Health Regulations. • • 5.03.08(6) Water Pollution 11 The construction, operation, and maintenance of the proposed electric transmission line and substation system will not result in any water pollution. Pollution of the surface run-off, stream flow or groundwater will be prevented substantially by limiting access to existing roads and trails, and by helicopter construction. Where soil disturbances occur at the structure locations, and substation sites, the disturbance will be kept to a minimum and revegetated (refer to Section 5.03.07(5)). The substation yard areas will be resurfaced with gravel and road base material. Any percolation tests or groundwater resource tests which may be required by local or state health officers will be met before operation of the facilities. 5.03.09 USES NOT ITEMIZED Public Service does not request this review to have the proposed facilities added to the list of permitted uses in the zone districts involved. 1 I/ 1 1 11 1 1 1 11 -20- 1 • • 1 1 1 1 1 1 1 1 EXHIBIT F REQUIREMENT 5. 1 MAP OF ADJOINING LAND OWNERSHIPS 1 1 1 1 1 1 1 1 1 -21- 1 • • 1 1 1 1 1 1 1 1 EXHIBIT F1 LIST OF PROPERTY OWNERS • 411 EXHIBIT F1 List of Property Owners Following is a list of property owners within 200 feet of subject property lines: Mobil Oil Corporation I Attn: Tax Department P.O.

In this 1 case, Public Service is required to purchase power from CTDC. Alternative A - Tap Existing Rifle -Cameo 230kV Line Tapping into the existing Rifle -Cameo 230kV Line at the southeast corner of the CTDC project area would require the construction of one-quarter (1/4) mile of double circuit or two separate single circuit 230,000 volt lines. In addition, switching facilities would have to be constructed either at the tap point or at the CTDC Substation. This alternative is illustrated on Exhibit I-1. The Rifle -Cameo 230kV Line is one of the major East-West ' bulk power transmission system ties. Exposing this line to unnecessary interruptions of power flows creates an unacceptable degradation of the system reliability. The estimated cost of this alternative is $1,800,000. We find this alternative to be unacceptable due to system operating ' reliability and cost. Alternative B - Construct 230kV Line Along the North Line of ' Sections 20, 19 and 24 This alternative requires the construction of approximately 2.6 miles of single circuit -230,000 volt electric transmission line along the north line ' of Sections 20 and 19, Township 6 South, Range 92 West and the north line of Section 24, Township 6 South, Range 93 West, as shown on Exhibit I-2. The additional line terminations at Rifle Substation are the same as the ' proposed action. The estimated cost of this alternative is $1,250,000. ' Routing the line as required for this alternative creates another transmission line corridor from Rifle Substation. It would diverge from the existing lines beginning at the south one-quarter (1/4) corner of ' Section 17 to the CTDC property in Section 24. A maximum separation of some 1100 feet. I The line would be routed along the south side of the county road from approximately one (1) mile. There is a home located just north of the section line, 1800 feet east of the northwest corner of Section 19. 1 With the cost of this alternative being equal to the proposed action it would be proper to eliminate it from consideration due to the additional burden it places on the land and its proximity to the residence in Section II 17. 1 -30- 'a • • M • • 11111111,. • r m 10002 = il I 0 _ No 0 0 m 0 0 j. r" 7 %\t== �.� �/ V 44 1 O 0 w 0 0 r Z m 004 �y u / ) X �\ i''' \d:*''.., -•• / �1 1 ,Zn "'""t"••••,,,'"' 4:. rte:.
