BOCC 4/13/92 PROJECT INFORMATION AND STAFF COMMENTS Special Use Permit for industrial support facilities, specifically for the production of liquid hydrocarbons from natural gas. APPLICANTS: Colorado Clean Fuels LOCATJON: A parcel of land located in portions of Sections 34 & 35, T6S, R96W and Section 2 & 3, T7S, R96W; more practically described as a parcel located approximately two (2) miles northwest of Parachute, off of C.R. 215. SITE DATA: 241.23 acre site WATER: aEMEER: ACCESS. EXISTING ZONING: ADJACENT ZONING - Bottled drinking water and existing wells Sealed vaults pumped by licensed commercial sewage haulers. County Road 215 RIL - Lower Valley Floor R/L - Lower Valley Floor I. RELATIONSHIP TO THE COMPREHENSIVE PLAN The subject property is located in District D - Rural Areas, Moderate Environmental Constraints. II. DESCRIPTION OF THE PROPOSAL A. Site Descri tp ion: The site is a relatively flat valley floor area, located between the County Road and Parachute Creek. Presently the site has industrial support facilities used for the upgrade, storage and transport of crude shale oil. A railroad spur comes into the site from the south and extends along the west side of the site and the eastern boundary is C.R. 215. B. Project Description; The applicants are requesting the issuance of special use permits for industrial support facilities for industrial operations for the production of liquid hydrocarbons from natural gas, in addition to the existing permits issued to Unocal for the shale oil upgrade facility. It is proposed by the applicant to use the existing Unocal upgrade facility, with some minor modifications to manufacture methyl alcohol (methanol), smokeless diesel fuel, premium grade naphtha and Fischer-Tropsch (F -T) wax from natural gas. It is proposed to produce 4500 barrels per day (BPD) of all of the products noted previously, with 4200 BPD of the production being methanol. The proposed process will utilize the existing upgrade facility, truck loading facility, railroad spur, natural gas pipeline and power line. At the upgrade site, the Unocal dearsenator, Unicracker, Unifiner, dewatering equipment, pretreatment facilities, sulfur and ammonia removal equipment will not be used as a part of this process. The applicant will add an F -T vessel, methanol synthesis loop, PDX vessels and a waste heat recovery system to the existing facility without removing any of the existing equipment. While these portions of the existing facility will not be utilized, it should be noted that they will remain on site for future shale oil upgrading. This application will only allow one of the proposed production processes to occur at one time. Should Unocal or a new owner of the property reinitiate shale oil production, the applicant's processing of natural gas will discontinue. The principal means of transporting the methanol will be by rail. It is projected that two to three times a month, a 100 car (30,000 gallons/car) unit train will go out of the area to the proposed markets. If for some reason the train transport is unavailable, the methanol can be shipped by truck out of the existing truck loading facility. If this alternative is used, it would result in approximately 24 truck trips daily. All other products will be shipped by truck, at a rate of less than one truck per day for each product. During construction, it is estimated that 110 workers will be employed at the peak of the 10-12 months it will take to add the new equipment and modify the existing facilities. During operation, there will be an estimated 21 full time employees. C. Background: Unocal received a number of permits in 1981 and 1982 for the upgrade plant and various associated facilities. While Unocal has suspended their shale oil production, the facilities are not being removed, thus, all of the permits issued previously are still valid. III. MAJOR ISSI JES AND1T ONCERNS 1. Zoning: The requested land uses are proposed to be added to the existing and uses already permitted. Because the zoning resolution does not have a provision for modifying or amending a special use permit, the requested permits have be considered new permits to be added to the existing permitted uses. The applicant has submitted an impact statement to supplement the previously accepted impact statements submitted by Unocal in support of their existing land use permits (see application pages 15-20) and the supporting documentation noted further on in this report. In summary, the impact statement says that the proposed new process will comply with the existing state and federal permits and that the impacts will be less than the present facilities due to a smaller level of production and less toxic byproducts. Any approval of the proposed project should require compliance with previously approved resolutions of approval, as well as any new conditions of approval. 2. Air emissions from the proposed project are projected to be less than the existing permitted levels. Concerns have been expressed about the applicants ability to transfer the existing permits to the new operation. Enclosed are letters from the U.S. Environmental Protection Agency and Colorado State Department of Health, Air Pollution Control Division (see page ). The EPA letter notes the transfer process to another owner is "quite simple." The EPA letter also notes the PSD (Prevention of Significant Deterioration) permits previously issued by them is new the responsibility of the Colorado Air Pollution Control Division. The CDH Air Pollution Control Division set out a procedure that does not appear to present any major obstacles. Prior to receiving these letters, staff had conferred with the Grand Junction Air Pollution Control Division representative, who indicated that the transfer procedure was relatively simple and ministerial in nature. 3. Enclosed are supplemental statements from the applicant further clarifying the type of reclamation that would occur and that there will not be any unacceptable impacts due to sound and vibration (see pages ). 4. Enclosed is a letter from Joyce Risley, expressing concerns about the emission of nitrogen oxide and carbon monoxide (see pages ). IV. SUGGESTED FINDINGS 1. That proper publication and public notice was provided as required by law for the hearing before the Board of County Commissioners. 2. That the hearing before the Board of County Commissioners was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at the hearing. 3. That the application is in compliance with the Garfield County Zoning Resolution of 1978, as amended. 4. For the above stated and other reasons, the proposed use is in the best interest of the health, safety, morals, convenience, order, prosperity and welfaret citizens of Garfield County. V. RECOMMENDATION APPROVAL, subject to the following conditions: 1. All proposals of the applicant shall stated otherwise by the Boa of County Co a� itzeti iral permits shall be submitted prior 2. That copies of all transferre to issuance of any special use permit. onditions of approval unless is ioners. 3. That all conditions of approval contained in Garfield County Resolutions No. 81-11, 81-12, 81-281, 82-158, 82-186, 82-145 and 86-30 shall be complied with by the applicant. • f I. UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION VIII 999 18th STREET - SUITE 500 DENVER, COLORADO 80202-2405 Ref: 8ART-AP April 2, 1992 Garfield County Commissioners 109 8th Street Glenwood Springs, Colorado 81601 Dear Commissioners: • it ii Unocal has requested that EPA provide you with information about the procedures required to transfer the existing Unocal Prevention of Significant Deterioration (PSD) permits to the Clean Fuels. Development Corporation. The procedure for transferring the PSD permit of an operating source from one owner to another owner is quite simple. It is done by notifying the issuing agency of the name, address and contact of the new owner and acknowledging that the new owner will operate the plant in accordance with the PSD permit. However, there is a problem in transferring a PSD permit for a source that has-been shut down. If the source was temporarily shut down, the PSD permit is valid only if,the source will be operated in the same way that it was operated before the temporary Shut down. Any changes in the method of operation would require that the new owner obtain a new or modified permit from the permitting authority. The federal PSD regulations in 40 C.F.R. 52.21(r) state, "Any owner or operator who constructs or operates a source or modification not in accordance with the application submitted pursuant to this section or with the terms, of any approval to construct ..., shall be subject to appropriate enforcement action." It is our understanding that Clean Fuels Development Corporation does not plan to operate the Unocal plant in the same way that it was previously operated before the .temporary shut down in June 1991. Therefore, a new or modified permit must be obtained to allow Clean Fuels Development H Corporation to operate as planned. The permitting authority ford% any new or modified permit is the Colorado Air Pollution Control.:' Division. The Division now has the authority to issue PSD permits, as well as all other construction permits for sources in Colorado. If you would like to discuss any questions related to transferring PSD permits to another owner, please contact John Dale at (303) 294--7611 or Carol Smith at (303) 293-1768.

INTRODUCTION Union Oil Company of California, Oil._ Shale Operations (hereinafter "the Applicant") proposes to construct and operate a 10,000 BPD shale oil upgrading plant in Garfield County three miles north of Parachute, Colorado. On September 29, 1980, the Applicant requested permission from the U.S. Environmental Protection Agency, Region VIII (hereinafter "the EPA") to construct the proposed complex pursuant to 40 CFR 52.21 (Review of Major Sources and Major Modifications). The EPA issued a public notice in Rifle Telegram, a newspaper of general circulation in the area on March 11, 1981. The notice proposed approval of an air quality permit for the source and gave opportunity for public comments during the ensuing 30 calendar days. The permit application, and the proposed permit and its supporting analysis were made available for public inspection at the Office of the Garfield County Clerk in Glenwood Springs, Colorado. The public comment period was extended to May 11, 1981. On May 6, 1981, the Applicant submitted proposed changes to the plant design. A summary of written comments appears in appendix II. II. FINDINGS On the basis of information in the administrative record (see appendix I for partial listing), EPA has determined that: 1. The applicant will meet all of the applicable requirements of the PSD regulations. 2. No applicable emission or ambient air quality standard will be violated by the emissions from this source. Zo -2- 3. EPA has good reason to Relieve that the Company can comply :•ritn the conditions of this permit. However, in the issuance of this permit, EPA does not assume any risk of loss which may occur as a result of the commencement of construction and operation by the . Applicant if conditions of this permit are not met hy the Applicant. 4. The stack parameters used for modeling are contained in Table IV. III. CONDITIONAL PERMIT TO CONSTRUCT AND OPERATE On the basis of the findings set forth in II above, and pursuant to the authority (as delegated by the Administrator) of 40 CFR 52.21(r)(2), EPA hereby grants conditional approval for the Union Oil Company of California, Oil Shale Operations to commence construction and operation of shale oil upgrading plant.

Application Analysis (EPA) 5/20/81 Comment 1: -10- APPENDIX II Union Oil Company of California Summary of Public Comments Our greatest concern with the permit as proposed was the virtually complete consumption of SO2 increment in the Parachute Creek valley by the emissions that would have been . permitted. This could have affected operations of the Colony Shale Oil Project under its existing PSD permit. Response 1: The modeling technique used to predict the impact is considered to be very conservative and thereby predicated an increment consumption greater than what mould actually occur. Union Oil Company submitted design modifications on May 6,.1981 which resulted in a large decrease in SO2 emissions. This modification has alleviated the commenters concerns. Comment 2: Response 2 Comment 3 We were further concerned that the consumption of SO2 increment which would have been allowed by the proposed permit would have placed an unreasonable burden upon other operators who may in the future Trish to construct and operate shale oil processing facilities in the vicinity. As was noted in response 1A, the predicted increment consumed • was on the high side. The burden placed on future operators is' one of determining the maximum accumulated impact from their source combined with the existing increment consuming sources. The design modification has alleviated the commentors concerns. We had substantial concerns about the adequacy of the PSD permit application in regards to the application of Best Available Control Technology for the control of sulfur dioxide emissions from the upgrading facility. These concerns have noir been mitigated by the design modification. Response 3 Specific concerns were not expressed. Comment 4 The permit application indicated that control options other than a four -stage claus plant were available to Union which would more effectively and economically control sulfur dioxide emissions from the proposed upgrading facility. Response 4 Seven SO2 control strategies were evaluated in the control technology review to determine what should be required as best available control technology (BACT). IIACT was the emission • limit based on the maximum degree of SO2 reduction, taking into account energy, environmental, and economic impacts and other costs, determined to be achievable for the source. More efficient control options than the proposed four -stage claus plant were evaluated. However, they were not more economical' in the control of SO2 emissions. The modification has alleviated the comrnentors concerns. -11 - Convent 5: The modeling approach is unduly conservative in that it over -predicts the degree of increment consumption and impact on - ambient air quality standards likely to occur from construction and operation of the upgrading facility. Response 5: (See Response 1A) We agree with the conmentor which supports our original determination that the SO2 increment will be protected. An applicants burden under 52.21(k) is.to demonstrate that the applicable increments will not be violated. For convenience, an applicant can use conservative modeling. Future applicnts, in the impact area, must make an independent showing under 52.21 (k) and are not bound by previously predicted impacts. Conimentors Date Gerald D.

Applicability Determination Maximum potential emissions for the proposed 10,000 barrel per day size plant to upgrade and fractionate raw shale oil in the original application were as follows: Potential emissions (tons/year) SO2 NOx Particulates NC CO Process and combustion 201.7 320.7 8.7 5.0 29.7 Storage tanks, pumps, loading 90.9 Locomotives 1.0 7.1 0.6 3.4 Vehicle travel 1.7 Totals 202.7 327.8 10.4 96.5 33.1 Union submitted a number of design changes on May 6, 1981 which resulted in a signficant decrease in the sulfur dioxide emissions and minor net increases in the other pollutants. The revised maximum potential emissions for the plant area are as follows: Process and combustion SO2 NOx Particulates HC CO 35.7 327.1 10.6 6.1 36.3 Storage tanks, pumps, loading 91.1 Locomotives 1.0 7.1 0.6 3.4 Vehicle travel 1.7 Totals 36.7 334.2 12.3 97.8 39.7 The shale oil upgrading operation is considered to be a major stationary source.

Additional information was requested on October 30, 1980 and received on November 24, 1980. Supplemental modeling information was received on December 1, 1980 and January 26, 1981. A modification to the design was received on May 6, 1981. C. Stack Heights Good engineering practice (GEP) stack heights for the reformer furnace, sulfur recovery unit and hydrogen charge heater were determined to be 150 feet (46 meters) in chapter 6 of the application. The revised sulfur recovery unit stack height will be 34 meters. All other stacks are 30 meters or less which meet the requirements of GEP. D. Control Technology Review A control technology review was done for sulfur dioxide, nitrogen dioxide and volatile organic compound emissions. The rationale for the technology to be used is contained in Chapter 5 of the application. The best available control technology (BACT) analysis is described in a technical memo dated March 4, 1981. It was determined that Union will utilize BACT controls. The design modifications received on May 6, 1981 decreased the potential SO2 emissions from 202.7 tons/year to 36.7 tons/year which is below the significant emission limit. Therefore a BACT analysis is no longer required for SO2 emissions. E. Air Quality Modes The short term maximum concentrations were modeled using Woodward -Clyde Consultants, (WCC) version of the EPA PAL model. Annual Concentrations were determined using the WCC version of the EPA Valley Model. A description of how the models were modified and used are discussed in chapter 6 of the application. An evaluation of the models used is contained in a technical memo dated March 9, 1981. F. Air Quality Analysis The ambient concentrations were determined from the monitoring stations located at Tracts C -a and C -b as well as earlier monitoring done by Union Oil. A summary of the maximum concentration is shown on Table 6-3 in the application. G. Ambient Air increments Maximum concentrations of sulfur dioxide emissions from the Union operations were calculated to be 78.8 ug/m3 over an 24-hour period when the emissions were 202.7 tons per year. With the design change submitted on May 6, 1981, the sulfur dioxide emissions decreased to 36.7 tons per year which would significantly decrease the maximum concentrations. However, since the potential SO2 emissions are below the significant emission limit, an air quality analysis is not required. ri -15- The total predicted NOx concentrations were estimated t9 be 19.6 ug/m3 and when added to the background amounted to 57.6 ug/mi which is below the national standard of 100 ug/m3. The validity of modeling results is discussed in a technical memo dated March 9, 1981. No violations of increments or ambient standards were predicted.

Source Information The original application dated September 29, 1980 contains most of the information needed to make the required determinations in the PSD regulations. Additional information regarding Union's proposed emission monitoring program, emissions from locomotives, emissions and operation of the emergency flare, and supplemental sulfur control strategies were provided in a.letter dated November 18, 1980. Additional modeling descriptions and results were provided in letters dated November 26, 1980 and January 26, 1981. A modification to the design was made on May 6, 1981. I. Additional Impact Analyses Visibility impacts were discussed on page 6-37 of the application and were determined to be insignificant at the Flat Tops Wilderness Area. Starting on Page 6-39, an analysis of the impacts on soils and vegetation is presented. Conclusions from the analysis are that impacts will be from slight to negligible. With the additional reduction of the SO2 emissions, impacts would be reduced. J. Public Participation The application, analysis and proposed permit were made available for public inspection at the EPA offices in Denver, and the Garfield County Clerk's office in Glenwood Springs. The Colorado Department of Health issued a public notice in the Rifle Telegram on January 28, 1981. EPA gave opportunity to request public hearing and a 30 day public comment period by a public notice in the Rifle Telegram on March 11, 1981. The public comment period was extended to May 11, 1981 and public notices were issued in the Rifle Telegram and the Denver Post. Three written comments were, received and considered in the final permit. These comments are summarized in the summary of public comments (appendix II of the permit). • A 'lit COLORADO DEPARTMENT OFAHEALTH • 4210 East 11th Avenue Denver, Colorado 80220-3716 Phone (303) 320-8333 April 2, 1992 Telefax Numbers: Main Building/Denver (303) 322-9076 Ptarmigan Place/Denver (303) 320-1529 First National Bank Building/Denver (303) 355-6559 Grand Junction Office (303) 248-7198 Pueblo Office (719) 543-8441 P ROY ROMER Governor JOEL KOHN Interim Executive Director Garfield County Commission 109 Bth Street Glenwood Springs, W 81601 Dear Sir: APR 8 1992 GARFIELD COUWY APR 61992 COLI TY COMMISSIONERS Mr. Leon Pahler requested we send a letter regarding a transfer of ownership of air pollution permits from Unocal to Clean Fuels Development Corporation.

Nichols UNOCAL 10735 County Road 215 Parachute, Colorado 81635 Dear Mr. Nichols: Mr. Leon Pahler requested we send a letter regarding a transfer 'of ownership of air pollution permits from [hxocal to Clean .Bels Development Corporation. Transfer of ownership of State issued permits requires the following: 1) Submittal of revised Air Pollution Emission Notices (APENs) for each 'emission point with the required $60.00 Filing Fee for each notice. These Apens must note the method of operation of each emission point. 2) Submittal of an application form. 3) A statement noting that the source will be operated is such a manner that it will not be considered a modified source. Upon receipt of this information the Division will review the Apens and redraft the permits. A fee letter will then be sent to cover•the Division's cost of processing the request. Once the fees are paid the permits are issued. The Unocal situation does require that Prevention of Significant Deterioration (PSD) issues be addressed. Currently the U.S. EPA retains authority for Unocal's PSD permits. Since the PSD permits were issued, however, the Colorado Air Pollution Control Division has taken over the PSD Program. Consequently PSD issues must be addressed with': the Division prior to issuance of new permits. It is likely that. ati "emission netting' procedure can be employed to simplify the PSD review., Ci priuiedon reeyekelP.iper I i -Page two - Y would suggest that Clean Fuels Development Corporation meet with the Division to discuss these issues prior to making an application.

In the event Colorado Clean Fuels does not exercise its option to purchase the facility at some point during or at the end of the 15 year lease term with Unocal, the terms of its lease agreement with Unocal specifically provide that "upon the termination of this lease, lessee shall surrender the premises to lessor; provided, however, lessee shall have a period of up to one year from the date of termination of the lease to remove all buildings, improvements, equipment and personal property owned by lessee on the premises and return the premises to lessor in the same condition as when received, ordinary wear and tear excepted. Lessee shall repair any damage to the premises occasioned by the removal of lessee's buildings, improvements, equipment and personal property." Colorado Clean Fuels' rehabilitation plan for the duration of the lease is to return the facility to Unocal in its existing condition. Therefore, in the event Colorado Clean Fuels returns the facility to Unocal, any obligations for site rehabilitation that Unocal currently has will remain with Unocal, after Colorado Clean Fuels completes its obligations to remove its buildings, improvements, equipment and personal property. 9085 East Mineral Circle, Suite 350 Englewood, Colorado 80112 Phone: (303) 792-3037 Fax: (303) 792-5603 _q g 27405 Puerta Real, Suite 340 Mission Viejo, California 92691 Phone: (714) 582-0373 Fax: (714) 582-0642 • i1 Garfield County Board of County Commissioners 4/6/92 Page 2 In the event Colorado Clean Fuels exercises its option to purchase the facility at some point during or at the end of the 15 -year lease term with Unocal, it will become obligated to rehabilitate the site if the facility is decommissioned and abandoned. Colorado Clean Fuels expects that a one-year period in which full rehabilitation would be accomplished is a reasonable time period, consistent with the rehabilitation timing provided for in its lease agreement with Unocal. Rehabilitation is construed by Colorado Clean Fuels to mean the removal of all equipment, buildings, fixtures and other structures and the restoration of topsoil to excavated areas, along general topographic contours that were present prior to the initial construction of the facility. I trust that the above clarifies our intentions, expectations and obligations understanding in the event the facility is decommissioned and abandoned.
