15. Revised page 2.05-181.10 omitted a portion of the last sentence of the second paragraph under the Fish <br />Creek section. The following language has been deleted, "and a maximum of approximately 39.9 acres <br />would be flooded during high water by mining panels 12- through 16 -Left. " Please revise the page to <br />include the omitted information. <br />Response: - The referenced page has been reviewed and revised to address this omission. Revised copies of the <br />referenced page accompany these responses for replacement in the PAP. <br />16. Revised page 181.11 repeats the last paragraph of the section regarding the Fish Creek Alluvial Valley <br />Floor and the paragraph regarding Stock Ponds on revised page 2.05-181.10. Please review these <br />proposed revised pages and remove the appropriate duplicate information. <br />Response: - The referenced pages have been reviewed and revised to address the noted duplicate text. Revised <br />copies of the referenced pages accompany these responses for replacement in the PAP. <br />17. Revised page 2.05-181.11 indicates for the WCR that the following structures and renewable resource <br />lands overlie the mine area: Pasturelands, Scott Farmstead, Routt County Road 33 (RCR33), Powerlines, <br />Telephone Lines, Union Pacific Railroad Energy Spur, Stock Ponds and Irrigation Ditches. Revised Map <br />23 and the currently approved Maps 23b and 23c do not depict all of the structures and renewable <br />resources lands within the permit and adjacent area. Rule 2.05.6(6) (a) (ii) requires that an appropriate <br />map, prepared in accordance with Rule 2.10 showing the location and configuration of the structures and <br />renewable resources lands within the permit and adjacent area, be submitted. The definition of <br />"renewable resource lands" is found at Rule 1.04(110). Please submit a map that depicts the renewable <br />resource lands within the permit area and adjacent area, the Scott Farmstead, the Telephone Lines and <br />Irrigation Ditches. <br />Response: - Map WC23B currently shows the County Road, railroad spur, potentially affected powerline, and <br />identifies land use areas, and ponds, ditches and springs. Detailed delineation of land use areas is provided by <br />Maps 3 and 3A (shading or hatching these areas on this map would make the map un -readable). The Scott <br />Farmstead (long abandoned and now owned by TC) is further to the west and does not fall within the mapping area <br />for Maps WC -23 and WC -23B. <br />18. PRIO included Exhibit 7K,• Wolf Creek Reserve Subsidence Evaluation. Drawing 2 of Exhibit 7K depicts <br />the layout of the Wolf Creek Seam Panels. These seam panels do not correspond to the mine plan <br />submitted and depicted on revised Map 23. Given this, it appears the evaluation was based on a different <br />mining plan. Please submit anew subsidence evaluation based on the updated mine plan. <br />Response: - The revised and updated subsidence evaluation and associated text revisions provided as a <br />supplemental submittal on March 19, 2015 address this Comment. <br />19. Rout County Road 33 was not included in the subsidence evaluation submitted with Exhibit 7K. Given this, <br />it is unclear what the worst possible subsidence consequences will be. Please evaluate the worst possible <br />subsidence consequences of mining in the Wolf Creek seam based on the mine plan submitted with PR10. <br />Please indicate if the worst possible subsidence consequences will result in material damage or diminution <br />of reasonably foreseeable use of RCR33. If so, please submit the information required by Rule <br />2.05.6(6) (b) (ii). <br />Response: - The revised and updated subsidence evaluation and associated text revisions provided as a <br />supplemental submittal on March 19, 2015 address this Comment. <br />20. Revised Page 2.05-181.12 indicates two powerlines may be impacted by subsidence from mining in the <br />Wo f Creek Reserve. One line is described as being located north of the 18RT gate road and within the <br />19RT Panel (NMD). The other powerline is the Yampa Valley Electric Line. Exhibit 7K evaluated <br />subsidence impacts on three lines, the Archer -Hayden Powerline, Craig -Hayden -Steamboat Powerline and <br />the Foidel Creek -Steamboat Powerline. Please re-evaluate which powerlines will be impacted by the <br />
