XVIII. Mine Facilities Coal Handlin Structures, and Su ort Facilities <br />The mine facilities, support facilities and coal handling structure portion of <br />the application can be found on pages 85-92 of Volume I. Major facilities <br />include a 58-acre office-shop and preparation plant area at the Roadside <br />Portal and a similar 62-acre surface facilities area associated with the Cameo <br />No. 1 mine. Clean coal is transported from the wash plant at Roadside <br />approximately 1.3 miles to the rail loadout north of the Cameo mine via a 36" <br />overland conveyor. The 0.1 mile section of the conveyor which is suspended <br />over the Colorado River is totally enclosed. The loadout facility occupies 55 <br />acres and includes a clean coal storage area and a non-discharging sewage <br />lagoon. Raw coal is transported by truck from the Cameo mine to the wash <br />plant at Roaside. <br />No problems relative to the requirements of this section were noted during the <br />review. <br />The proposed operation is in compliance with the requirements of this section. <br />XIX. Roads (2.05.3(3). 4.03 <br />Information on roads is presented in Section 2.05.3 of Volumes I and V of the <br />permit application. <br />There are two haul roads, seven access roads and five light use roads within <br />the permit area. The road designs were checked for compliance with the design <br />standards of 4.03. All the roads meet the design criteria for grade and <br />surfacing. <br />Several problems relating to road drainage were noted by the Division during <br />the course of the review. No justification for culvert size or justification <br />that ditches were adequately sized was given. The applicant supplied <br />information on the existing culverts and ditches. All were found to be in <br />compliance except two pipe arches under the haul road near the Cameo mine. <br />These pipe arches had an end area of greater than 35 square feet, therefore, <br />to be in compliance with Rule 4.03.1(4)(3)(1) they must pass the 20-year, <br />24-hour peak flow. The applicant subsequently submitted a plan to improve the <br />culvert inlets to increase the available capacity. After receiving approval <br />from the Diviiion, the applicant reconstructed the inlets to meet regulatory <br />requirements. <br />The applicant also did not supply adequate information to prove that the three <br />dip-sections are designed to pass the required flows. However, information in <br />the Division's files shows that all three dip-sections do not meet design <br />standards. The two upper dip-sections have six 36-inch culverts, which in <br />aggregate have an end area greater than 35 square feet. Therefore, they must <br />pass the 20-year, 24-hour peak flow to be in compliance with Rule <br />4.03.1(4)(e)(i). The lower dip-section is only required to pass the 10-year, <br />24-hour peak flow to be in compliance with Rule 4.03.1(4)(e)(i). However, <br />this dip-section will not pass the 10-year, 24-hour peak flow without <br />overtopping. <br />-34- <br />
