We have the following <br />questions and comments: <br />Rule 2.05.3(3) Operation Plan — Permit Area — Mine Facilities <br />1. Table 19 — Surface Facilities, contains a list of all facilities at the mine, indexed by the <br />map on which they are shown. <br />Please update table 19 to include the changes made to Map 11 Sheet 1. Specifically, the <br />RDA Belt Addition and the Explosives /Chemicals storage area should be added. <br />2. Page 2.05 -7 describes conveyors. <br />Please update page 2.05 -7 to describe the RDA BeltAddition. <br />Rule 2.05.3(3) Operation Plan — Permit Area — Mine Facilities and Rule 4.03.1— Haul Roads <br />3. The material submitted seeks to change the approved design of the RDA haul road. The <br />design that had been previously approved (with TR66) met the specifications laid out in <br />Rule 4.03.1(3) — Design and Construction. The revised design should address all of these <br />criteria, specifically: <br />a. (Vertical Alignment) The profile drawing suggests that although the overall <br />grade is < 10% and the maximum grade is < 15 %, there is a —800' long segment <br />of the road with a grade in excess of 10 %. <br />b. (Horizontal Alignment) No issues. <br />c. (Width) The design on Map 11 — Sheet lshows a minimum width of 15'. <br />d. (Road Cuts) The design on Map 11— Sheet lshows a maximum cut slope of <br />1.5h: Iv, or 0.25h: Iv in rock, which is accordance with the specification. <br />e. (Road Embankments) The design on Map 11 — Sheet lshows a maximum fill <br />slope of 2h: Iv, or 1.3h: Iv where the fill is 85% rock, which is slightly steeper <br />pF C0 <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us I *� <br />John W.
