Burgmaier <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver CO 80203 <br />303 - 866 -3567 x 8111 <br />http://mining.state.co.us <br />H Susan, <br />reviewed the certification, and I do have a few comments. <br />Firstly, it proved to be a bit of a challenge to find the permit sections that address the haul road in question. Bits <br />of information are scattered about, but I eventually located Map 16 Haul Road Plan & Profile (Volume II), Typical <br />Cross Section Haul Road (Volume V Eng Dwg HR -1), and the haul road text (Volume I Pages 2.05 -31 and -32). <br />Gob Pile #3 itself is addressed in Volume M. <br />1. In the first paragraph, the stationing of the road is given as 0 +00, which it is on the Plan and Profile provided. <br />However, this stationing differs from what was used on Map 16, the approved design. A note should be added <br />following 0 +00, something such as "this equates to Station 4 +_ on Map 16 ". <br />2. The third paragraph addresses compaction of the subgrade materials and the road base. The Buckhorn test <br />sheets represent different levels of compaction and different test methods that what is shown in the certification. <br />The certification should be revised to show the following: <br />For Subgrade (native soil), the test method is ASTM D 698, ASTM D4718 Method A, and compaction was <br />required to be > 95 %. <br />For Class 6 Road Base, the test method is ASTM D1557 Method C, and compaction was required to be > 95 %. <br />https: / /mail.g oog le.conVmai I /u /0 / ?ui =2 &i Ire29129fcb5 &viev�-- pt &search =i nbox&th= 140bae4f7c4e829e 1/3 <br />
