The following questions and comments are outstanding: <br />Rule 2.05.3 (3) Operation Plan — Permit Area — Mine Facilities <br />1. Item resolved — NECC added the items "DWDA Belt (RDA Belt Addition)" and <br />"Explosive /Chemical Storage" to Table 19, under the heading for Map 11 — Sheet3, East <br />Portal Facilities <br />2. Page 2.05 -7 describes conveyors. <br />DBMS - Please update page 2.05 -7 to describe the RDA Belt Addition. <br />NECC — Please refer to the enclosed page 2.05 -7d <br />DRMS For clarity, please describe the approximate location of the conveyor in the text. <br />(Note that the conveyor is labeled `Refuse Conveyor Belt" on Map 11- Sheet 3) <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 />pP CC310 <br />e <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us <br />John W.
