Afro, revera! <br />gullier described in the Divirivn s November or August inspec[ion reports were not delineated on the 2004 plan <br />map, including a ride slope gully up to 18"deep that parallels the 005 Gulch Channel far several hundred feet, <br />revera! hundred yards above the Duck Pond, several additional hillslope gullies in the 1997reclamation parcel, <br />and an area of headcutting erosion located along the southern perimeter of the `A"Pit disturbance area, below the <br />dragline tub facility site. Please address these concerns and amend the map as appropriate. <br />Rather than attempting to delineate all individual hillslope gullies m the parcel where <br />contour ditches will be reclaimed, a genera/ commitment to sec/aim all hillslope gullies Y <br />or deeper within the specified reclamation parcels would be acceptable. <br />Response: SCC has revised Drawing 22-4.1, Rill and Gully Plan - 2004, to address your concerns <br />and the requirements of Rule 4.14.6, Regrading or Stabilizing Rills and Gullies. The revised drawing <br />indicates general areas in which potential rills and gullies exist. The need for repair will be <br />evaluated/determined in the field. Evaluation will include whether the rills and gullies will prohibit <br />successful revegetation or disrupt the achievement of the postmining land use. <br />The locations of excessive erosion (noted in Division inrpedion reports) along the proposed postmine <br />drainage channels that have not been constructed or finished to date are shown on the revised map. <br />The repairs/remediation will be accomplished during the construction and/or reconstruction of the <br />approved postmine Channels. These channels are part of the TR-45 submittal <br />Please replace the existing Exhibi[ 22-4.1, Rill and Gully Plan - 2004, with the attached updated <br />version. If there are any questions regarding these responses, please contact me @ (970) 275-5227. <br />Sincerel <br />~~ <br />Roy A.
