Please review the referenced chart and correctly describe the volumes of temporary <br />overburden that are proposed to be stockpiled on the East Taylor Fill, West Taylor <br />Fill, final cut area of the Section 16 Pit and Section 16 Pit reclamation. Please <br />include a chart and description of these volumes in the text under Rule 4.09 - <br />Disposal of Excess Spoil, which begins on Page 20 (South Taylor/Lower Wilson-Rule <br />4, Page 20) in Volume 12. <br />Response: The chart below reflects the original temporary stockpile volumes approved <br />with PR-02 and indicates the changes to the temporary stockpile volumes requested by <br />TR-81. <br />Temporary Fill <br />Volumes <br />PR-02 <br />TR-81 <br />Section 16 Fill 13, 315, 915 0 <br />West Taylor Fill 0 9,173, 000 <br />East Taylor Fill 29, 849,199 40, 900, 000 <br />Total 43,165,114 50, 073, 000 <br />17. In Colowyo's response to incompleteness question 1 (the Division's 14 September <br />2009 Incompleteness Letter) a chart is included that shows permanent and temporary fill <br />volumes for the East and West Taylor Fills and the temporary overburden stockpiles. A <br />reconstruction of the permanent fill volumes (from the 7 December 2009 Colowyo response <br />letter) is shown below. <br />Permanent Fill <br />Volumes <br />PR-02 <br />TR-81 <br /> <br />West Taylor Fill 49,934,000 10,000,000 <br />East Taylor Fill 20,409,000 50,000,000 <br />Total 70,343,000 60,000,000 <br />The Colowyo chart does not match the volume information contained in the Colowyo <br />Permit. The approved text on Page 20 (South Taylor/Lower Wilson-Rule 4, Page 20) <br />states "The East Taylor Fill will contain approximately 50 million yards of permanent out-of- <br />pit spoil and the West Taylor Fill will contain approximately 10 million yards of out-of-pit <br />spoil." The proposed text from TR-81 states "The East Taylor Fill will contain approximately <br />20.3 million yards of permanent out-of-pit spoil and the West Taylor Fill will contain <br />approximately 50 million yards of out-of-pit spoil." It appears as though the labels on the <br />columns of the Colowyo chart were transposed. Please verify and correct the volumes <br />for the East and West Taylor Fills. Please include a chart and description of the <br />permanent fill volumes in the text under Rule 4.09 - Disposal of Excess Spoil, which <br />begins on Page 20 (South Taylor/Lower Wilson-Rule 4, Page 20) in Volume 12. <br />Response: Please refer to chart below which provides the volumes of the East and West <br />Taylor Fills. We have also revised the text of the discussion regarding Rule 4.09 Disposal
