Alternatives No alternative routes were considered. The proposed route not only parallels a recently installed 12" high pressure natural gas pipeline, partly owned by Public Service Company of Colorado, but also shares part of the respective easement. Some additional right of way will be acquired which will expand and overlap the existing easement. b. Existing Corridors As stated above and shown on the accompanying plat, the proposed pipeline will be within a pipeline corridor for approximately 1400 feet of the 2600 feet, and within a county road corridor for an additional 700 feet. The remaining 500 feet is along the perimeter of PSCo's existing compressor station. c. Reasons for Selected Route The pipeline route was selected first for the existing corridor and second the existing right of way. As with the first pipeline the route was also selected because of the surrounding terrain. There are several arroyos in the area that are best traversed at right angles if possible, which was the case for the first pipeline and now the second pipeline. And finally, the route is one of the shortest possible routes between the two facilities. 3. PROTECT DESIGN SECTION 3 a. Detail of Construction With the exception of the facilities at either end of the pipeline, both of which are currently permitted under special use, all of the proposed construction will be underground piping with a minimum cover (dirt above the pipe) of four feet. Subject to availability and contractual agreements, the source and direction of the flow of natural gas can change frequently. The pipeline will be tested to safely operate at 1000 psi. b. Plan of Operation Engineering , construction, and operation of the proposed facilities will be performed by or under the supervision of qualified personnel, pursuant to PSCo's policies, and standards, established by the Department of Transportation as contained in CFR Title 49 Part 192. The requirements of the Occupational Safety and Health Act will be followed in the construction and operation of the subject facilities. PSCo's right of way agents or representatives will personally meet with the landowners and/or tenants of the properties to be traversed by the route. During these meetings, landowners' requests for special construction and restoration requirements would be factored into PSCo's overall environmental program. Once the right of way acquisition is complete and necessary permits are acquired, a pre -construction survey and staking will take place. This would include staking of the permanent and construction easement at 100 foot intervals. Many of the stakes will remain throughout the cleanup and reclamation activities. After the rights of way have been surveyed and easements secured, portions of the 50 -foot -wide right of way will be cleared of vegetation, rocks, and debris. The right of way will then be graded as necessary to provide a relatively level surface for trench excavation equipment and for the safe passage of heavy construction equipment. Debris generated will be removed and properly disposed of at the direction of PSCo in conformance with applicable state and county regulations. Topsoil will be removed and segregated. Care will be taken to control erosion. During this initial phase, temporary fences will be established, where necessary, to control livestock and prevent unwanted traffic. The trenching crew will then excavate a ditch approximately three feet wide and to a minimum depth of five feet to provide a least 48 inches of cover over the buried 8 -inch pipeline. The width at the top of the trench will vary with soil conditions and slope stability. The ditch will be excavated by either a track - mounted or rubber tired backhoe, or similar trenching machine. In areas where bedrock is too solid or extensive to trench, pneumatic hammers or blasting will be used to remove the rock. Materials removed during the trenching operation will be temporarily placed on one side of the trench. There are no plans to construct containment structures around the stockpiles due to their temporary nature. Pipe will be shipped in double random lengths, varying from 40 to 44 feet, and strung along the right of way. Pipe joints will be welded together in long sections and placed on temporary supports at the side of the trench. Welds will be visually inspected, X-rayed, and repaired a necessary. The entire pipe will be coated and electronically inspected to locate any faults or voids in the coating. The pipe will then be lowered onto the trench. The trench will be backfilled with previously excavated materials and the right of way graded to pre -construction contours, except for a slight crown of soil to compensate for the natural subsidence of the backfill. In rock areas, the pipeline is protected with appropriate padding material. After backfilling, a cleanup crew will remove all materials and debris from the site. Excess trench materials will be spread uniformly over the construction zone or removed to a suitable location. The final process will be to place the stored topsoil over the trench and to areas from where it was removed. Slopes will be stabilized by seeding or other appropriate method in rangeland areas. Fences will be restored to their pre - construction condition or better. c. Work Force The anticipated size of the work force is expected to be 12 people. The entire work force will be temporary for the three week duration of the project. Ongoing operations and maintenance will be accomplished with existing employees. d. Construction Equipment Type Number Size (Typical) Backhoe 1 Cat 225 Backhoe 1 Case 580 Lowboy 1 Bulldozers 1 Cat D6 Side Boom Crawlers 2 Cat D6 Flatbeds 1 2 Ton Welder Units 2 Pickups 4 e. Nitrogen Gas Testing When completed the proposed pipeline will be tested with nitrogen gas to operate at 1,000 lbs psi. The test gas will be vented to atmosphere following the test. 4. PROTECT COSTS SECTION 3 The anticipated cost of the project, including right of way acquisition, surveying, materials, construction, and reclamation is $190,000. 5. PROTECT SCHEDULE SECTION 3 Public Service Company would like to start the project as early as September 6, 1994 for completion by September 30, 1994. We recognize that this may be an unrealistic time frame, however, we will be prepared to begin on that date and will assist the County in any way possible to achieve that goal. 6. LAND USES SECTION 4 a. Description of lands The land involved with this project is arid rangeland dedicate to essentially two uses; grazing, and oil and gas processing and transmission. There is no irrigation or cultivation involved. b. Easements Two easement are required for the pipeline. One from William Clough and a second from Northwest Pipeline Corporation. The requested width will be for a 50.0 foot easement with a 25.0 foot overlap of the existing easement for most of 2,655 feet of pipeline. All right of way acquisition will be accomplished by Public Service Company employees. c. Eminent Domain Public Service Company of Colorado, by state statute, is granted the right of eminent domain. It is unlikely that there will be any involvement with condemnation proceedings with this project. In any case, every request, option, and alternative will be reviewed prior to entering in to a condemnation process. d. Road Crossings Two road crossing are involved with this proposed construction. One is Garfield County Road 264, which is improved dirt/gravel at the crossing location, and the second is an unimproved access road. To limit the impact on adjacent property owners, both roads will be open cut and properly compacted. e. Acreage Approximately three acres of land are impacted by this proposed project. f. Access Easements will be accessed by way of existing roads. During construction, contractors and employees will be required to limit and control access and vehicular traffic in a manner that will protect the public and livestock from hazards associated with construction. 7. PROTECT IMPACTS AND MITIGATION SECTION 5 a. Agriculture Agricultural uses are currently limited to livestock. The general impact will be loss of grazing material over the areas disturbed. The damages, resulting from this disturbance, will be assessed jointly by the owner and the Public Service Company and the owner will be properly compensated. b. Soils The soils in the areas of disturbance sustain limited amounts and varieties of vegetation. They are also subject to moderate to high erosion factors for which PSCo will pro -actively use best management practices to minimize erosion and promote stabilization following installation of the pipeline. The area will be continuously monitored for erosion and general reclamation. c. Vegetation The area is dominated by sagebrush and indigenous grasses. The disturbance will be of a short duration and in much of the area, the root systems will be left undisturbed. Immediately following construction, the areas of disturbance will be reseeded using a seed mixture recommended by the Soil Conservation Service. Areas will be continuously monitored and supplemented until reclamation is successful. d. Air Resources There is no permanent impact on air resources. The low precipitation and low relative humidity which generally found in this immediate area will add to fugitive dust problems created by the proposed construction. If necessary dust will be controlled by watering of the right of way. e. Water Resources The major water body with this project is the Colorado River approximately 4/5 of a mile to south, and at an elevation 70 to 80 feet lower than the project area. The pipeline also crosses a generally dry stream bed north of County Road 264 in Section 13, Township 6 South, Range 94 West. Due to the short duration of the project and the time of year construction will take place, there should be little or no impact on the stated water body or drainage area. f. Wetlands There are no wetlands involved or affected by this project. g. Wildlife & Wildlife Habitats The general wildlife resource in the area along the pipeline is upland in nature. The area of disturbance however, is subject to significant vehicular traffic, and oil and gas related activities. For these reasons, there are marginal wildlife habitats that would be only temporarily affected along the pipeline route. No mitigation measures should be needed. In addition, there may be some involvement with livestock. If necessary, a livestock control fence will be installed to protect animals from open trenches and other construction hazards. h. Visual Impacts As previously stated all additional facilities involved with this project will be underground, with no above -ground appurtenances. The visual impacts therefore, will be temporary resulting from the loss of ground cover. These impacts will be mitigated through revegetation, which will be repeated as if necessary to achieve an acceptable revegetation. i. Mineral Resources The proposed pipeline project has no relative impact on mineral resources. j. Dust and Erosion Both fugitive dust and erosion are factors that will require attention on this project. Dust will be controlled with water when necessary during construction. A review and analysis will be conducted when construction is complete to determine what erosion control methods will be initially required, both short and long term. Following construction, the route will be routinely monitored for erosion and the success of the reclamation efforts. k Drainage No changes in grade or contours will be necessary with this construction. Historic runoffs should not be affected and there will be no permanent impact on any floodway or flood plain. 1. Cultural Resources The area of construction has been heavily impacted by pipeline construction, and other oil and gas activities. Unless otherwise directed, no record search or site review will be conducted. However, if during construction any artifact or evidence of historic or cultural interest is found, the relative activity will be stopped and the State office of Historic Preservation will be notified. m. Impacts on Local Governments and Special Districts Likely impacts on local governments and special districts will be with county road maintenance and traffic during construction. Post -construction impacts will be essentially limited to fire protection and emergency response. No other utilities or services will be required as a result of this project. n. Noise & Vibration There are no noise or vibration impacts involved with this project. The pipeline project is a pipe only project. Associated metering equipment is located at both end points in the facilities approved for this use. No other facilities are required or involved. o. Vapor Occasional releases of natural gas can occur at the connected sites during maintenance and operation. This gas is not odorized at these points and therefore undetectable. In addition, these releases are in volumes that are non -explosive in nature. No significant impact is involved. 8. HAZARDS & MITIGATION SECTION 6 In addition to the hazards associated with the actual construction, there are marginal hazards from fire and explosion associated with the operations of the pipeline. Nationwide, experience has shown the primary cause of natural gas pipeline accidents, resulting in fire and/or explosion, is third party damage, i.e. outside force, such as construction or excavation equipment. To minimize the associated hazards, Public Service Company has an ongoing pipeline marker program as well as a continued commitment to the "One Call" program. The Company also engages in frequent safety awareness programs, using various media sources, including its own billing functions, as a means to present safety information. With that said, it should be noted that pipelines have the best safety record among all major U.S. transportation systems. 9. EMERGENCY PROCEDURES SECTION 6 Copies of the Gas Emergency Plan and Procedures are available upon request. Names, phone numbers, and some procedures in the plan were revised in July of 1994, and the entire emergency plan is now being reviewed for approval by PSCo management. 10. WATER REQUIREMENTS SECTION 6 The single water requirement for this project is for dust control during construction. The water needed for this purpose will be purchased from a local source and transported to the site as needed. 11. TRAFFIC GENERATION SECTION 6 During the course of construction multiple trips daily will be generated involving pickups, single axle flatbeds, and occasionally a lowboy delivering pipe and equipment. The routes most likely used will be I-70, State Highway 6 & 24 and County Road 264. There will be minimal traffic to and from Rifle, primarily for meals and lodging. The staging areas for this project will be the gas processing facility at the west end of the pipeline, and the PSCo Rifle Compressor Station at the east end. 12. RECLAMATION SECTION 6 Reclamation will be provided by a contractor specializing in revegetation and soil stabilization. Seed mixtures evaluated by the contractor or will be requested from the local Soil Conservation Service office. The surface of the ground along the proposed route will be fine graded and disked prior to broadcast seeding. If needed a mulch and tackifier will be added. 13. ADJACENT PROPERTY OWNERS.

SUMMARY STATEMENT SECTION 1 Public Service Company of Colorado (Public Service Company or PSCo) submits this Special Use Permit application pursuant to Colorado Revised Statute 30-28- 110 and Conditional and Special Uses Section 5.03.07 of the Garfield County Zoning Resolution. Public Service Company, in conjunction with the Rifle to Avon system reinforcement project, presently under construction, proposes the construction of an 8" high pressure natural gas pipeline in Section 18, Township 6 South, Range 93 West, and Section 13, Township 6 South, Range 94 West, west of Rifle Colorado. The pipeline will serve as a interconnect between Public Service Company's Rifle Compressor Station and the natural gas processing facility jointly owned by Public Service Company and Rocky Mountain Natural Gas Company, which is also presently under construction. The interconnect will tie natural gas transmission and supply systems within the area bound by Grand Junction, Vail, Craig and Rangely. The result will be an enhancement of system flexibility for purposes of both supply and competitive marketing. The route for proposed pipeline will substantially parallel a recently installed 12" natural gas pipeline for approximately 1300 feet from the new gas processing facility on the west end of the project to Garfield County Road 264. At this point it will then turn east and parallel County Road 264 for 1200 feet to Public Service Company's Rifle Compressor Station. The total length is 2655 feet and lies primarily on the property of William Clough, with a small encroachment on Northwest Pipeline Corporation property.
