1. The refuse haul road was designed before Colorado gained primacy for <br />surface inspection and therefore the original design and referenced standards <br />are from 30 CFR part 817. The referenced standards were re- numbered, with <br />the appropriate Federal standards listed as 30 CFR 817.150 and 30 CFR <br />817.151. The corresponding CDRMS standard is Rule 4.03.1. <br />The cut and fill slopes and road surface, along with the design criteria used <br />for location, vertical and horizontal alignment, comply with Section <br />4.03.1(1). <br />B. Access Roads <br />Access roads are discussed under Section IV.H.3 of the permit application. <br />1. The mine permit area includes five access roads. All access roads meet the <br />requirements of Section 4.03.2, with the exception of the conveyor /loadout <br />access road. Based on information presented in the operator's relevant <br />showing submitted December 2, 1996 and CDRMS inspection observations, <br />a variance from the access road location requirement was approved for the <br />conveyor /loadout access road, pursuant to 4.03.2(1)(e). <br />II. Support Facilities - Rule 4.04 <br />Support facilities are discussed under Sections IV.B, IV.C, IV.D, IV.H, IV.O and IV.P <br />of the permit application. <br />A. Construction of support facilities will not result in damage, destruction, or <br />disruption of oil, gas, or water wells or pipelines, coal slurry pipelines, railroads, or <br />utility lines which pass over, under, or through the permit area. Utility lines pass <br />through the permit area but are not affected by the support facilities. Therefore the <br />Division previously approved those activities (4.04(6)). <br />III. Hydrologic Balance - Rule 4.05 <br />Volume 1, Section II.0 of the Deserado Mine permit application includes an <br />assessment of the probable hydrologic consequences of the proposed mining operation. <br />Each year, Deserado assesses the ongoing impacts to the hydrologic system in its <br />annual hydrologic report. The probable hydrologic consequences as set forth in <br />Volume 1, Section II.0 are summarized below. The small area exemption sites are <br />listed in Section IV.J.5 of the permit application. Sedimentation demonstrations for <br />small area exemptions are provided in Illustration 44, of Volume 12, and the locations <br />are shown on Map 147. <br />A. Water Quality Standards and Effluent Limitations <br />With the exception of approved small area exemptions, all discharges from the <br />Deserado Mine will pass through sediment ponds or treatment facilities designed <br />Deserado Mine Permit Revision 07 <br />C- 1981 -018 28 29 June 2011 <br />
