The following are the sections of land which will be generally affected by the proposed use: Township 5 South, Range 96 West Sections 12, 13, 23, 24, 25, 26 and 36 Township 5 South, Range 95 West Sections 7, 18, 19, 30 and 31 The affected land lies on property owned or controlled by the applicant and by Union Oil Company. Evidence of the acquisition of appropriate rights-of-way from Union will be forwarded at a later date, Attached to this application you will find the following supporting documents and information: (1) Two sets of preliminary plans for the plant access road. Please note that these plans indicate that they consist of 90 sheets. Twelve orthomosaic maps (twelve sheets) are missing. These missing maps are used for pictorial pur- poses only and are not essential to an evaluation of the engineering design of the road. (2) Two sets of geotechnical reports (a total of four copies) on the plant access road Mr, Walter Milner February 28, 1974 Page 2 and mine access road. An additional geotechnical report on the valley access road is not considered necessary because the geotechnical conditions along this road are similar to those previously evaluated in the reports for the mine bench and plant access roads. (3) Two copies of a rehabilitation plan for all three roads entitled "Landscape and Erosion Control for Parachute Creek", A third copy has been delivered under separate cover to the Board of County Commissioners. (4) Two sets of alignment and property maps which indicate the location of the proposed roads. At this time, detailed plans for the roads identi- fied as the "mine bench road" and "valley access road" are not available. These roads are still being designed. The drawings and rehabilitation procedures applicable to the plant access road, however, are typical of the design and procedures which will be used on the mine bench and valley access roads. (5) Two sets of specifications which supple- ment the "Standard Specifications for Road and Bridge Construction", promulgated by the State Department of Highways, State of Colorado, January 1, 1971, which will be utilized during road con- struction, (6) Two copies of an impact statement as required by Section 4.03.07(1) of the Zoning Resolution, A third copy of the impact statement has been delivered under separate cover to the Board of County Commissioners, The applicant respectfully requests that the discretionary requirement to post adequate security to ensure the performance of the applicant's rehabilitation plan be waived in connection with this permit. Because the cost of rehabilitation is minor compared to the overall capital expense of the access roads, there is little inducement to shortcut the proposed rehabilitation methods. In addition, County officials will be able to Mr. Walter Milner February 28, 1974 Page 3 moniter construction activities to determine whether or not the applicant is conforming to its proposed plans. Furthermore, in view of the applicant's established reputation and financial strength, the bond is unnecessary. In accordance with our telephone conversation of February 28, 1974, because the proposed use does include structures subject to building code permit fees, the applicant has not submitted any permit fee with this application. Questions pertaining to the information contained in this application should be directed to this office or to Mr. Noel Piercy (telephone number 213/570-2845), who is more familiar with the design of the roads des- cribed in this application.

These documents are submitted to you in compliance with the provisions of Section 4.03.07 of tie Garfield County Zoning Resolution as adopted on November 27, 1973. For your convenience, a copy of the application to the Building Official (without attachments) is also attached for your review. Very truly yours, William Dixon Shay, Jr. WDSjr/bc Enclosures REC8VED Dok-4 IMPACT STATEMENT FOR PLANT ACCESS ROAD, MINE BENCH ROAD 'AND VALLEY ACCESS ROAD This impact statement is submitted by Atlantic Richfield Company in compliance with Section 4.03.07(1) of the Garfield County Zoning Resolution as a part of an application for a con- ditional use permit for a plant access road, mine bench road and valley access road in the upper Parachute Creek Basin. A broader impact analysis evaluating the envirbnmental impact of the entire shale oil complex and related facilities will be published in the near future and submitted to appropriate county officials for general informational purposes. The following summary is considered to be a complete response to the requirements set forth in Section 4.03.07(1). 1. Compliance with Local, State and Federal Laws and Regulations The fact that all of the proposed roads described in the the application for conditional use permit will be constructed on private land and will not be used by the public reduces the number of laws and regulations directly or indirectly applicable to the roads. In the interest of safety and sound engineering and design practice, the applicant intends to utilize voluntarily the standards for design and construction promulgated by the State Department of Highways, Division of Highways, State of Colorado. A copy of Atlantic Ricnfiel.d's application for authority to construct the roads described in this impact state- ment, filed with the State of Colorado Air Pollution Control Division on February 15, 1974 is attached hereto. As for Section 4.03.07(2) of the Garfield County Zoning Resolution, the applicant is currently studying the impacts associated with various modes of transportation to and from the plant complex in the Parachute Creek corridor and associated with off-site development in the greater Grand Valley area. Most of the projected vehicular traffic should be con- fined to these areas and should have a minimal effect on the balance of the county. The applicant does not expect truck and automobile traffic generated by the plant and its employees to constitute a hazard or nuisance anywhere in the county. As indicated more specifically in the following portions of this statement, the applicant does not expect the construction or operation of the access roads to interfere with existing uses of abutting property. The applicant therefore expects to comply with Section 4.03.07(3) of the Zoning Resolution without difficulty. Because the construction and operation of the access routes only indirectly constitute an "industrial operation", the applicant expects to comply with all of the provisions of Section 4.03.08 without difficulty. -2- The applicant is aware of no other Federal, State or local laws or regulations which specifically apply to the design and operation of the plant, mine and valley access roads. The applicant or its contractor will comply with all local ordinances could apply to sources and distribution of or codes which drinking water workers. 2. Water Utilization Drinking water for and sanitation facilities for road construction p construction personnel will be purchased from sources in Grand Valley classified as potable. Construction water used for dust suppression and compaction will be appropriated from local sources based on diversion rights in ,diddle Pork, Davis Gulch and East Middle Fork. If these diversion rights do not consitute an adequate source of water during construction, additional rights will be acquired in accordance with applicable state water laws. The rehabilitation plan entitled "Landscape and Erosion Control for Parachute Creek" contains a summary of the methods which will be utilized by the applicant to minimize siltation --- the most significant type of water pollution which normally results from road construction. Use of emulsified asphalt as a dust palliative will be limited to the maximum extent practicable to minimize potential water pollution attributable to this source. The applicant intends to arrive at an appropriate balance between application of chemicals and asphalt'r,ecessary for dust control and limited use of these materials to reduce potential water pollution. Equipment storage and maintenance areas for con- struction equipment will be diked to contain potential spills of fuel and other contaminants. To minimize disruptions of surface drainage patterns, the road designs incorporate ditches, cross drainage and other erosion control techniques (see rehabilitation plan submitted with application). The final road surface and year-round maintenance practices are not expected to constitute sources of significant water pollution. Maintenance procedures will be conducted in accordance with local practices. To minimize salt -induced damage to roadside vegetation, the applicant intends to restore roadside areas with salt. -tolerant species. Minor quantities of runoff containing salt used on road surfaces during inclement weather should constitute an insignificant contribution to the rather high total disolved solids concentrations of local streams. 3. Interference with Adjacent Land Use Regardless of whether the words "adjacent land", as used in Section 4.03.0'l(1)(b), are interpreted to apply to the immediate vicinity of the various access routes, or to adjacent land under separate ownership, the effects of "vapor, dust, smoke, noise, glare or vibration, or other emanations" gene- --4- rated by the construction and operation of the roads upon existing land use are expected to be minimal. As indicated by the composite property ownership map submitted with the application, most of the land in the vicinity of the proposed roads is owned or controlled by the applicant or Union Oil Company. Before the roads are constructed, appropriate rights-of-way will be obtained from Union Which will permit the construction of the roads and reasonably related activities. Union's consent to this right-of-way will constitute an acceptance of whatever interference results from emanations which will be caused by the construction and operation of the road. The anticipated emanations should consist of diesel exhaust, fugitive dust, noise associated with construction and the operation of vehicles, and vibrations produced by construction and vehicular activity. The plans, state specifications and supplemental specifications attached to the application show that adequate measures will be used to control fugitive dust. Diesel exhaust and vapors should be no greater than those which result from the construction and operation of any local road in Garfield County. Fumes produced by blasting activity will necessarily be temporary in nature and insignificant in effect. The canyon walls surrounding West Fork and Middle Fork should contain most, if not all, emanations generated by the construction and operation of the access routes, except for the portion of the plant access road planned for the plateau. The distances from this portion of this road to adjacent property, however, are great enough to reduce the potential interference attributable to emanations from construction and operation to insignificant levels. The only possible exception involves one isolated small tract of federal land just west of the proposed plant site, which is completely surrounded by private property. The potential interference with the existing use of this tract is expected to be minimal because of its inaccessibility, undeveloped character, and generally limited usefulness. It should be borne in mind that most of the land adjacent to the applicant's property is not amenable to commercial or residential development. If development occurs, it will most likely be industrial development similar to the proposed uses of the applicant. 4. Flora and Fauna The applicant has conducted extensive studies regard- ing the existing flora and fauna of the Parachute Creek Basin and the impacts which are reasonably expected to result from the construction and operation of the plant complex and related facilities. Based on these studies, the applicant does not expect any activity associated with the construction and -6- operation of the access roads to constitute a hazardous attraction to wildlife. Road kills will necessarily and unavoidably result from construction and operation of the roads. Protective fencing has been considered and rejected by the applicant's environ- mental consultants on the basis that the fences could result in greater harm by blocking access to forage and water. 9'According to these consultants, the proposed roads are not believed to cross any major migration routes. The consultants have recommended reconsideration of fences and animal underpasses at a later date if it is determined during construction or operation that the roads actually interfere with grazing or migration patterns. The method of construction described in the plans submitted with the application is a balanced cut--and-fill operation which should minimize total surface disturbance and destruction of existing vegetation as a result of road con- struction. Much of the land within the proposed corridors is only sparsely vegetated at the present time. In addition, the potential forage areas in the immediate vicinity of the upper portions of the access roads are somewhat inaccessable to foraging animals in the winter, the most significant season for foraging activity. The rehabilitation plan submitted with the application contains a detailed description of the measures to be used by the applicant to revegetate all disturbed areas. To -7- reduce potential road kills, consideration will be given to the selection of plant species for roadside planting which are not palatable to foraging wildlife. The applicant intends to discourage any illegal hunting activity on property within its control. , AIR POLLUTION CONTROL DIVISION - COLORADO DEPARTMENT OF HEALTH 4.4210 E. lith Avenue Denver Colorado - E'^^0' 3 Operated North of Grand Valley, Colorado 7.

February 12, 1974 C F Braun & Co 1000 South Fremont Avenue Alhambra, California 91802 Attention: Mr. Jerry Supple Gentlemen: Report Supplement No. 1 Geotechnical Studies ' Proposed Plant Access Road Colony Shale Oil Plant Parachute Creek, Colorado For Atlantic Richfield Company INTRODUCTION This letter supplements our report for the plant access road dated January 14, 1974. The location of the plant site for the project has been changed since the report was prepared. The new location of the plant site results in a new alignment of the plant access road; we were asked to evaluate the new alignment from a geotechnical point of view. The road alignment and the longitudinal profile prepared by International Engineering were made available to us and were carefully inspected. C F Braun & Co February 12, 1974 Page 2 CONCLUSIONS Our engineering geological mapping carried out in 1973 covered a relatively large area, and the new road lies almost entirely within the mapped area. Relatively simple geological conditions and our fairly detailed knowledge of the area enable us to evaluate the new road alignment from the geotechnical point of view, without additional field work. The new road alignment follows more or less parallel the West Fork alternative of the original road. The geotechnical conditions for both roads are thus very similar. The road will cross identical geotechnical units dealt with in detail in our original report. The road length and lengths of road sections within individual units have been changed. A summary of road sections within the more important geotechnical units is presented in Table 1.

Moline Project Manager AtianticRichfleldCompany Legal Division 1500 Security Life Building Denver, Colorado 80202 Telephone 303 266-3741 William Dixon Shay, Jr. Attorney May 10, 1974 Mr. Walter Milner Building Official, Garfield County 2014 Blake Avenue Glenwood Springs, Colorado 81601 In re: Access Routes; Conditional Use Permit Application Dear Mr. Milner: 44A. I/ On February 28, 1974, Atlantic Richfield Company ("the applicant"), acting for itself and other companies, applied for a conditional use permit for a plant access road, a mine bench road and a valley access road for a commercial shale oil complex in the upper Parachute Creek Basin in accordance with Section 4.03.07 of the Garfield County Zoning Resolution. This permit was approved by you on April 4, 1974 subject to the submission of evidence that appropriate rights-of-way had been obtained from adjacent landowners permitting the construction and operation of the roads. Subsequent to your approval of the original permit application, it became evident that rights-of-way for a significant portion of the plant access road on property owned by Union Oil Company could not be obtained in the near future. To avoid increased plant construction costs attributable to the expected delay, the applicant has altered the design of the plant access road to conform to the terms of an existing license agreement in effect with Union Oil Company. Notice of these changes will be given to the Colorado Air Pollution Control Division. The alternate plant access route traverses land wholly owned by the applicant. The applicant's right to use the portion of the previously approved valley access road which crosses Union Oil Company land is set forth in a Private Roadway License and Exchange of Shale Lands Agreement, dated September 14, 1970. Mr. Walter Milner May 10, 1974 Page 2 The following comments apply to the alternate plant access road: 1) The land affected by the use is unchanged from that described in the application of February 28, 1974, as shown on Exhibits I and II, attached hereto. 2) The original application included plant access road plans, geotechnical reports, a rehabili- tation plan, an alignment and property map, and specifications. Changes to these attach- ments necessitated by the alternate design are described below: a) Plans: The original application did not include plans for the valley access road and mine bench road because these roads were still being designed on the date of application. The design of the mine bench road has been completed and a set of plans is attached for your review. The design of this road should be considered typical of the design for the alternate plant access road. A set of plans for the alternate plant access road will be forwarded to your office in the near future. It should be noted that approximately 5.5 miles of the original alignments have not changed. A short connecting road of approximately 2.9 miles has been added while approximately 6.5 miles of the original road system have been deleted. b) Geotechnical Reports: Since the alternate route will cross the same geological formations as the old road, the reports previously furnished to you are still valid except for precise alignment and percentages of specific strata affected by the construction of the road. Mr. Walter Milner May 10, 1974 Page 3 c) Rehabilitation Plan: The rehabilitation plan remains unchanged and will be adhered to. d) Alignment and Property Map: As indicated previously, the alignment of the plant access road has been substantially changed. An updated alignment and property map is attached hereto. It should be noted that the current align- ment actually makes double use of approximately 5.5 miles of the originally approved system by routing all traffic over the valley access road and mine bench road as shown in Exhibits I and II. The property lines set forth on Exhibit III indicate that all of the property to be traversed by the alternate road is either owned or controlled by the applicant. e) Specifications: The specifications sub- mitted with the original application remain unchanged. f Design Changes: The alternate road has required certain design changes. Topo- graphical restraints rule out a balanced cut and fill operation, particularly in the area of the Middle Fork crossing. Exhibits IV through VII show the proposed disposal area for excess excavated material in the canyon, the under pile drain, and the 6 to 8 foot diameter culvert which will be used to divert the creek. The culvert has been designed to be larger than would otherwise be necessary to minimize potential erosion in the vicinity of the culvert. The fill will be designed for potential conversion to a mine bench at a future date. Appro- priate conditional use permit applications for the mine bench and associated structures will be submitted at that time. Mr. Walter Milner May 10, 1974 Page 4 Exhibit II indicates that the alternate route will cross the mouth of Davis Gulch on a dam crest. Until the necessary permits for construction of the dam have been obtained, the alternate road will temporarily bypass this area. 3. The original permit application included an impact statement prepared in accordance with Section 4.03.07 (1) of the Zoning Resolution. The original impact statement adequately describes the impact of the altered road system except as indicated below: a) Surface Drainage: Consistent with the general design goals described in the original impact statement the alternate plant access road will incorporate features intended to minimize disturbance to existing drainage patterns. Except for a temporary increase in siltation as a result of construction activity, the placement of the culvert at the Middle Fork crossing will not affect existing water quality or stream flow. The large diameter of the culvert and the under drain system have been designed to minimize potential erosion in the area affected by the road. b) Land Disturbance: By virtue of the shorter road length, less total surface disturbance will occur. The alternate alignment will actually reduce the total area to be disturbed by approximately sixty acres despite the fact that a balanced cut/fill operation is no longer possible. The alternative alignment in no way affects the continued validity of the manpower and scheduling information attached to Mr. Crowley's letter of March 14, 1974. The applicant requests that the waiver of applicable security posting requirements be extended to the altered alignment described in this letter. Mr. Walter Milner May 10, 1974 Page 5 The applicant believes that the alterations to the previously approved alignment are insignificant enough to be treated as an amendment to the original permit application. The provisions of the roadway license agreement currently in effect with Union together with the information provided by the letter should satisfy all applicable requirements. The applicant respectfully requests issuance of the conditional use permit in order that arrangements for the commencement of con- struction may be made as soon as possible.

Very truly yours, W. C. Milner Building Official WCM/tlb STATEMENT TO GARFIELD COUNTY COMMISSIONERS Union Oil Company of California has recently begun a comprehensive study for development of facilities designed to produce from 50,000 to 150,000 barrels of refined shale oil per day from its lands in Parachute Creek Valley. The study will include a detailed mapping program as well as determining the best sites for a demonstration plant, mines, retort plants, a refinery and shale oil storage areas. The study will extend over several months and take into account our improved retort technology as well as the complex economic and environmental elements associated with a project as large as this. Until this study has been completed, Union Oil feels that granting a right-of-way to Colony Development Operation for a road across our lands would be premature. The proposed Colony road would interfere with a prime refinery site in the West Fork and Union Meadow area. Union agrees with Garfield County's proposal to retain a consulting firm to study an access road system for the entire Piceance Basin shale oil industry and will give its technical and financial support to the study.
