The Grand Hogoack rormation has buu the majority of the site has gent.J-e slopes of 5 to I. RELATIONSHIP TO THE COMPREHENSIVE PLAN The proposed Special Uses are located in District B, Subdivisions/Rural Serviceable Areas, L/2 to I mile radius, moderate environmental constraints. Under the District B classification, the area falls within tne sub-category lb, which is an area witnin one (1) mile of a subdivision witn central water and sewer ano moderate environmental constraints. This sub-category classification is based on the Riverbend PUD location. II. DESCRIPTION OF THE PROPOSAL A. ^ 7- B.eroject oescription: It is proposed to modify tne Special Use ffi a coar mine- to prove the feasibirity of the -L-L.:f i!.- ^-; produce 2.2 million tons annually'Tnis permit, thougn, would bnly be for a pilot mlne tnat projects .a maximum of 960,700 tons of coal ber.ng iroduceO in 1987: in. foliowrng is tne projected production bY quarter: Quar Ler 1986 1987 4 Total iyaiauric minrng technigue, provide _ coal for washabirity and c6mbuscion tests and to provide small shipments to- the western coal spot markets. It i; proposed that the mine wiIl eventualJ-y I -0- 283,800 The following :.s a I approved in the Previousapplicatron: 1984 APP1ication 2 mine portals sediment Ponddewatering Plant slurry ponds sizing station shop ano trailers water treatment Plant par k ing coal storage PiIe access road 2 2L,6L2 283,800 3 B0 ,7 24 252,500 262 t278 140,600 364,6L4 960,700Lrm The major reason for the requested motJrfication is a result of the desire of NCEC to move the tunnel portals and associated facitities 1400 feet west of the originar ioc-ation' The relocation oi- -t.ire portals will reduce the length of the tunnels from 25OO ft. to 1750 ft. Adciitionally, the portals wij'I be separated, rather tnan be parallel, reducing the size of the cut into tne mountain. Each tunnel wiil be l-0 feec nigh and 16 feet wide and 60 ft.. nign. The same blasting technrgues will be utilized to oore tire new tunners' rst to compare the associated facilities application and tne reguested modified 1985 Application 2 mine portals dewatering Plantsizrng station sediment Pondsnop and traiters coal storage PiIeerectrical suostation access road 2 Lay down Yards2 powder magazines temporary tunnel muck storage water storage tanks rock handling Yard The dewatering prant will be sized to meet the needs of the operation, wnicir is approximately 150 ft.

The proposed access road has Deen moveci, each approximately 1100 feet, in an effort to avoio a large number of culverts that woulo be required in the previous location' Initial mining of coal will require the trucking of the material to a loadout iicrirty in Clenwood Springs. It +s. anticipated that this Ioadout roirta only be used during the inrtial stages of tne operation for somewhere between 20r000 to 30r000 tons of coal per -quarter. In the interim, various alternatives f or a |ermarient loaoout are being analyzeo. Separate permrts wiII be iequested for the permanent facility' "/ - This permit would result in a maximum employmeni.- level of 155 empfoyees the thirO quarter of 1986. The initial employment Ievel would De 51 in Mirch of 1985, peaking In August and going down to 47 by the end of 1987. Since the employment leveL will not exceed 200 at any time ouring the permit, NCEC Is asKing that if,"y-U" relieved of any responsibility for . revision of the pr"iriou" fiscal impa-t analysis and mitigatron program requirements. III.IVIAJOR ISSUES AND CONCERNS A.Staff Comments On December 27, 1984, Resolutron No. 84 -264, the Board of County Commissioners approved with tne folrowing conclitions of approval: I. 2. That all verbal and written rePresentations of the ippficants snal Oe considered conditions of apProvaI, unleSs "'pL.if ied otherwise by the Board of County Commissioners' That any permits issued wrll oe valid until Jury L,1988. That prior to the issuance of any Special Use permits: A. The applicant wiil revise the storm King Mines Fiscal Impact Assessment to reflect the current plan of opirations, and that the revised Fiscal Impact Assessment wilL be reviewed by tne affected governmental entrties and a mitigation plan establrshed [f,at is acceptable to the Board of County Commissioners. B. That the copies of aI1 other permits from other governmental lgencres regurretl for che proposed Special uses be submitted to tire Department of Development. c. That the applrcanc srrbmit a iandscaprng, Iighting and color schemL- plan for the facilities which minimizes visual impacts Lo tne extent reasonably feasiOle for the propbsed uses and is acceptable to the Board of CountY Commrssioners. That prior to the issuance of Special Use permits for extraltion, storage, water impoundment and mineral waste disposal, the followrng conditions be met: A. That the applicant agree to limit blasting activity to daytime houis if the noise impacts to nearby resioents is determineO Dy the Board of County Commissioners to be greater than Projected. B. That written verification from the Division of Water Resources of a legal l^,ater source be provided to the Department of Development/Plannrng Division' c.That written verification from the Town of Nev, Castle of therr alrility to accept tne sewage efftuent from Lhe project De submitted to the Department of Development/Planning Division. 3. 4. -5 nLi It has been proposed to paint structures a "ciesert tan with one horizontal white stripe.' A color sample will be provided. The lighting plan states that lignts will be placed such that the focus of illumination wiII be generally downward and at the aPpropriate facility or area. It is stated that every attempt will be made to avoid of f -site irnpacts. To specify specific iilumination and locations of structures i; not possible until the final engineering is completed. The applicant should agree to the same conditions of appiovaf vr:.tn regard to t'he blasting activities. The I{LRB in their preliminary f indings has determined that NCEC has more than aoequate water rights to develop the mtne. I'ILRB does have the Stite Engineerrs offrce verify the water rights. This would eliminate the necessity for this condition. The previous aPplication included a letter from the Town of New Castle expressing their willingness to work with the then Storm King Mines to dumping sevrage into the Town I s sewage treatment system. Tne Town Ivlanager has indicated that they aie still willing to work with NCEC on thrs lssue. (1-4) The traffic safety analysis is in process and will be submitted prior to issuance of the Special Use permit. The pavement thickness design is being performed by a gualiEied engineer and will be submitteo prior to issuance of the Special Use permit. This conoition may need to be changed given the proposed maximum production of 960r700 tons of ioal in L987. If production levels reach this point, a permanent loadout facility wiil be in place, which may not require trucring tne coal. The same condition of approval may be adequate for the interim period. IV. SUGGESTED FINDINGS That the meeting before the Planning Commission was extensive and complete, that all pertrnent facts, matters anO issues were submitted and that aII interested parties were heard at the mee E,ing i That the proposed Special Use conforms to Section 5.03 concerning the approval-or disapproval of a pecrtion for a Special Use, of the Garfield County Zoning Resolution; 3. That the proposed tand use will be compatible witn existing and permitted land uses in all directions provided certain conditions of approval are met; That for Lhe above stated and other reasons, the proposed Special Use permits are in the best rnterest of the health, satety, morals, convenience, order , prosper ity and welfare of the citizens of Garfield CountY.

That the proposed haul road De designed t^:ased upon a pavement thickness design performed by an engineer qualified to perform such a study. Further, that the Board of County Commissioners review the document and require the applicant build a haul road in accordance witn the specifications contained in the rePort. That based on the traffic safety analysis, a maximum number of truck trips per day be establisned for the hauling of coal and that a Iimited size of the operation be established. But, in no case, will the test mine exceed 960,700 tons of coal per year or an average of 54 round trip trucK trips per day on a monthly basis. - f - n\-,/C
