the process. <br />Resolved <br />DRMS Oct 2015 (New): Review of the Grading and Backfilling section of revised page Section <br />2.05.4 page 4 indicates that Approximately 44,000 cubic yards of material will be placed in the waste <br />bank. Please describe how this volume of material was determined. <br />Please describe if this is the same volume of material referred to in Trautner Report section 6.1 <br />Determination of Material Volumes as currently in place or, does this number (44, 000cf) reflect <br />additional material to be included so that post construction geometry can be established. <br />GCCE Dec. 2015: As mentioned above, he "earthmoving phase" of the Trautner report referred <br />to one scenario which called for temporarily moving the coal mine waste from the West Waste <br />Bank, installing an underdrain system, and replacing the material in 12" — 24" lifts. Instead, the <br />material was simply moved to the permitted refuse pile and placed as per approved designs. <br />44,000 cubic yards refers to the designed volume of the West Waste Bank, when it is finally <br />constructed. Currently, all coal mine waste has been removed from the West Waste Bank area, <br />the area has been graded per Trautner's recommendations, and preliminary trenches have been <br />established in preparation for construction of the underdrain system (pending approval of this <br />TR). <br />DRMS: This portion of'the comment is resolved. <br />However, the permit does not appear to address the inspection requirements. Please revise the Mine <br />Waste Rock Disposal narrative in Section 2.05.3 of the permit to include inspection elements and <br />frequency for the West Waste Bank. <br />GCCE Dec. 2015: Although inspection requirements are addressed in 6.5.1 of Trautner's report, <br />Section 2.05.3 page 3 has been revised to address inspection elements and frequency. <br />Resolved <br />Please provide dates of any inspections and any findings and recommendations suggested by Trautner <br />or other inspector. <br />GCCE Dec. 2015: Dave Trautner, P.E. performed a pre -construction conference on-site inspection <br />with Marcia Talvitie of CDRMS, Wayne Dale of Stoner Engineering, and GCC engineering <br />personnel. This inspection occurred to solidify Division and engineering requirement for the <br />projects. These requirements were included in the June 29, 2015 Trautner report. As <br />mentioned previously, there is currently no coal mine waste at the West Waste Bank location <br />pending approval of TR -20. <br />Resolved <br />DRMS Oct 2015: DRMS is in receipt of the 2015 Second Quarter Inspection Report of the King I mine <br />refuse pile conducted by Stoner Engineering on 29 June 2015. This inspection revealed no issues. <br />Please provide DRMS the Third Quarter 2015 King 1 refuse pile inspection report. <br />GCCE Dec. 2015: The Third Quarter 2015 King I refuse pile inspection report has been provided <br />to the Division via email. <br />Resolved <br />DRMS Oct 2015: I have received the 6 July 2025 Quarterly Waste Pile Embankment Inspection <br />Prepared by: R. Reilley April 2016 <br />File location: M:\ Coal\ rar\ 1MKingCoal\ TR20 Page 7 <br />
