13. Colowyo has provided a new Appendix Exh7-14D - Section 16 Fill Ditch. There <br />appears to be a pagination problem with this appendix. The numbering starts on page <br />Exh. 7-14D-1, continues to Exh. 7-14D-2 and Exh. 7-14D-3 then returns to Exh. 7-14D-2 <br />(which is different than the first page Exh. 7-14D-2) and continues on after that, in order, <br />from Exh. 7-14D-4 to the end of the section. Additionally, on page Exh 7-14D-3 there is <br />no actual text or SEDCAD but a statement that says "Insert multiple pages from <br />SEDCAD pdf files from Exh 14..." This page is either in error or additional pages need <br />to be added to this appendix. Please check the pagination of Appendix Exh7-14D - <br />Section 16 Fill Ditch and correct as necessary. <br />14. In the third paragraph on page 4.05-6 Colowyo provides text that identifies where the five <br />stock tanks can be located in the permit. The text states "The locations of these <br />impoundments are shown on Map 12 - Hydrology-South." These impoundments are also <br />shown on a very good figure on page Exh. 7-14R-8. Please add this reference to the <br />end of the above sentence so it reads "The locations of these impoundments are <br />shown on Map 12 - Hydrology-South and page Exh. 7-14R-8." <br />15. Please change the text in the second line of the last paragraph on page 4.05-2 from <br />"...appropriate annual report." To "...Annual Reclamation Report." <br />16. Colowyo has provided an updated Map 29 - Spoil Grading. This map changes shape of <br />the spoil grading polygons from the previously approved spoil grading map and moves <br />up final reclamation of the East Pit from 2017 to 2016. There are two problems with the <br />reclamation blocks as shown on the updated Map 29. First, There is a small, <br />approximately 1.5 acres, block to the east of the 2010 reclamation block, basically in the <br />location of stock tank PD 1, that is not being shown as reclaimed and does not have a <br />reclamation date associated with it. Please explain what this small feature is and <br />please include a reclamation date with it. Second, There is a larger block, <br />approximately 10 acres, just north of the 2019 topsoil stockpile reclamation block that is <br />not being shown as reclaimed and does not have a reclamation date associated with it. <br />Please explain what this reclamation block is and include a reclamation date with it. <br />This concludes the second adequacy review for the Colowyo Mine's Technical Revision 87. <br />Please contact me at (303)866-3567 X8145 if you have any questions or comments. <br />Sincerely, <br />James R. Stark <br />Environmental Protection Specialist <br />cc: Sandy Brown, CDRMS <br />Matt Guptill, Colowyo
