The exploration operation was granted a Special Use Permit (No. 144) on December 5, 1977. The crushing activity is proposed on federal land adjacent to issued federal coal leases as described in the original sub- mittal. The proposed support facilities are addressed further in the attached supporting information. If there are any questions, or a need for additional information beyond what is attached, please contact me. Sincer4ly, William C. Bosworth Director, Environmental Affairs Attch • • • TABLE OF CONTENTS SUPPORTING INFORMATION MAP No. 1 Location Map - Leases/Site Map MAP No. 2 Vegetation/Soil's map of site area DRAWING No. 1 Pictoral and plan view of equipment • • • SUPPORTING INFORMATION APPLICATION FOR CONDITIONAL USE PERMIT GARFIELD COUNTY, COLORADO SHERIDAN ENTERPRISES, INC. • SPECIFIC ACTION REQUIRING CONDITIONAL USE PERMIT Site preparation, assembly of prefabricated portable coal crusher/screen, and use of equipment on site in conjunction with activities described and covered under Special Use Permit No. 144, granted to Sheridan Enterprises, Inc. on December 5, 1977. The requested use area is located in T7S, R102W, Section 29 as shown on the attached maps. SITE PREPARATION No major earthmoving activities are contemplated. Initial earthwork will involve the construction of access, the levelling and landform modification necessary for the use of the proposed site, and the construction of necessary hydrologic control structures. All suitable and salvageable topsoil will be removed from the area to be affected and stockpiled for eventual use in reclamation. Topsoil will be stockpiled in the vicinity of the disturbed area through placement by the equipment used for removal. A sedimen- tation control ditch will be constructed around the perimeter of the stockpile and will drain to a sedimentation basin prior to discharge into the natural drainage channel in the vicinity. The topsoil stockpile will be seeded to wheatgrasses and mulched to prevent excessive erosion in the interim period prior to reclamation. ASSEMBLE EQUIPMENT The portable crushing equipment will be transported to the site by truck on Colorado Highway 139 (Douglas Pass Road) and will be assembled on site as shown in Map No. 2 and in the drawing depicting plan and pictoral views of the equipment. USE OF PROPOSED SITE The originally described scope of operations will not change except for the relocation of the crushing operation from the Mesa County rail loading facility to the proposed Munger Canyon site. No increase in tonnages extracted or transported over Colorado Highway 139 will exceed that which was outlined in the original Special Use Permit. The proposed modification involves an additional step in the overall scope of operations created by the relocation of the crushing activity. The coal will be transported from the test site stockpile to the crushing site whereupon, following crushing, • • Page 2 USE OF PROPOSED SITE (cont.) the coal will be loaded into on -highway vehicles and transported to the Mesa County rail loading site. The site may also be used for storage of supplies incidental to the exploration operation. The site area will, like the adjacent access/haul road, be wetted as required to eliminate a source of fugitive dust through vehicu- lar traffic. The stockpile (coal) will be wetted as necessary to eliminate a source of coal dust. It is important to note, however, that the coal will be transported to the crushing site immediately after extraction and will exhibit moisture from the water applied during mining to control respirable dust underground. This will further negate any potential for excess fugitive dust from the coal stockpile. USE OF EQUIPMENT The equipment to be utilized at the site was designed to have every feasible environmental control incorporated to achieve optimum environmental benefits. These controls are as follows: o Design of the equipment includes the enclosure of the crusher and covers over the screens. o Screens will filter the coal so that only 25% of the coal delivered from the test mine site will be crushed. o Water will be applied at appropriate intervals in a contained area during operation. o The elevation of the conveyor will be adjustable to pro- vide for a minimum fall of the product to the stockpile. Dust fall monitoring will be provided in the area of probable im- pact and used as a running check. This data can be provided to the County on a monthly basis. The equipment is shown in pictoral and plan view in the attached drawing. DESCRIPTION OF AREA The site proposed for the staging/crushing activity is isolated from Highway 139 and completely remote from any residences. It is located on a disturbed vegetative area in the valley bottom that is intermixed with bottomland sagebrush and greasewood com- munities. The disturbed area occurred as a result of past ranch- ing activities and appears to be related to uses associated with grazing in a holding area. The disturbed area contains numerous weedy species of vegetation, the most common being Russian thistle. Few shrubs grow on the area. • The site is immediately adjacent to the area previously approved under Special Use Permit No. 144.
