-56- <br />S2, AS INDICATED ON DRAWING N0. MG-R C-001, INCLUDED IN THE PERMIT <br />REVISION APPLICATION. DURING THE INSTALLATION OF THESE TILT METER <br />TUBES, THE OPERATOR SHALL AUGER AND LOG THE SURFICIAL AND BEDROCK <br />STATIGRAPHY ENCOUNTERED. AUGERING SHALL CONTINUE UNTIL THE <br />OPERATOR HAS ESTABLISHED INTACT BEDROCK OCCURRENCE. IF ANY <br />EVIDENCE OF EXISTING LANDSLIDE DEPOSITS IS ENCOUNTERED, THE <br />OPERATOR SHALL DEFINE THE NATURE AND EXTENT OF THE PRE-EXISTING <br />SLOPE INSTABILITY. IF SUCH LANDSLIDE ACTIVITY IS DISCERNED, THE <br />OPERATOR WILL BE REQUIRED TO APPROPRIATELY RECONFIGURE THE PILE <br />DESIGN, PRIOR TO INITIATION OF ANY CONSTRUCTION ACTIVITY. <br />The Division finds that the operation is in compliance with the <br />requirements of this section. <br />XIX. Mine Facilities, Coal Handling Structures, Suooort Facilities <br />The mine facilities, support facilities, and coal handling <br />structures sections of the permit application have been reviewed by <br />the Division and are in compliance with the Act and rules. The <br />mine facilities and support facilities portions of the permit <br />application can be found in section 3 of Volume 1, and in Volumes <br />4, 5, and 6 which contain construction specifications for these <br />facilities. The coal handling structures section can be found on <br />page 3-34 and pages 3-75 to 3-78 of Volume 1. <br />XX. Roads (2.05.3(3), 4.03) <br />The roads sections of the permit application are found on pages <br />3-23 to 3-24K of Volume 1 and in exhibit 3.1.1.E. <br />The permit revision application includes a proposed access road, to <br />be used to transport waste to the proposed upper waste pile site. <br />This road would be an approximately 2,500 foot long cut-section, <br />gravel surfaced road with grades up to 10 percent. Because of the <br />inaccessibility of the proposed road alignment, the applicant has <br />not completed a geotechnical investigation of the road corridor. <br />In fact, the completion of a geotechnical investigation would <br />require the pioneering of a roadway. The operator has requested <br />that permission be granted to complete the geotechnical <br />investigation and final design as the road is excavated. <br />Construction of the existing roadways and surface facilities at the <br />Mt. Gunnison No. 1 Mine has entailed extensive geotechnical <br />investigation, including angering and materials testing. Numerous <br />stability analyses have been completed to analyze proposed <br />operational and reclaimed road configurations. The proposed <br />roadway will involve many similar lithologic strata and slope <br />stability situations. For this reason, the Division believes that <br />the necessary material strength information probably exists with <br />which to complete the necessary design exercise, as long as <br />conservative assumptions are made, and later verified prior to <br />
