Trapper Response to Comment 24: The pre -strip operation at Trapper Mine is currently removing <br />approximately 150 feet or more of overburden to the H seam east of active L pit. That material is being <br />hauled around to the west side of the L pit to be used for reclamation backfill. In October 2016, this section <br />at E 1,441,000 was pre -mining topography. Near the end of our 5 year permit term in 2022, this same <br />section would be near the open cut to Q seam, which represents approximately a 350 feet elevation <br />difference from the pre -mining topography. <br />25. For the Lancaster Pit, please provide the following cross sections <br />at: a. N402,000 <br />b. <br />N404,000 <br />C. <br />N406,000 <br />Trapper Response to Comment 25: The requested cross-sections are enclosed. <br />As per Rule 2.05.3(6)(b), plans must describe the geotechnical investigation associated <br />with the disposal area. After reviewing the proposed changes as well as the currently <br />approved Trapper PAP, DRMS was unable to locate any geotechnical investigation for the <br />proposed excess spoil area at the Utility Waste Disposal area. <br />26. Please provide results of a geotechnical investigation of the proposed disposal <br />site along the utility waste disposal area. <br />Trapper Response to Comment 26: Trapper does not consider the material hauled from N pit to the <br />Utility Waste Disposal Area as "Excess Spoil." Therefore, we feel that no geotechnical investigation is <br />warranted. <br />27. Please describe and provide a diagram of runoff routing and indicate the <br />receiving water body for runoff emanating from the utility waste disposal <br />area. <br />Trapper Response to Comment 27: With the additional material from N Pit that will be utilized to <br />create the "ridge feature" that appears on the M 12 Map, the water will be routed both north and south <br />of the proposed contours and will drain east into the Johnson Drainage Area, near Johnson #6 Pond. <br />This run-off will be routed through the existing constructed drainage in Johnson Gulch. <br />28. With respect to revised page 3-15a paragraph 6, please discuss why language <br />was removed regarding placement of spoil as a buttress to the North of K pit as <br />per AAI recommendation? It seems to be pertinent information to the <br />description of spoil disposal as per Rule 2.05.3 (6)b. <br />
