Mule deer populations in Colorado are on the decline in <br />quality and quantity. Therefore, to minimize impacts to the mule deer population in the <br />proposed mining area, the Division recommends that the applicant move the Phase I access <br />road so it extends directly east from the excavation area, minimizing vehicular disturbance to <br />the south of Phase {, along the crest of Naturita Creek Canyon. <br />The application should also include commitments to crush material only between April 1 and <br />October 31 of each year and to limit the material hauling hours to the period from one half <br />hour after sunrise to one half hour before sunset during the winter months from November 1 <br />to March 31 . <br />12.The soils information provided with the application indicates a minimum of 15 inches of <br />material over the gravel bed. Without documentation to the contrary, the Division will assume <br />that this much soil material exists on site and will require that a minimum of 12 inches be <br />replaced. It is recommended that all available soils be replaced on the areas to be reclaimed. <br />13. Please indicate how much disturbance will exist in Phase II just prior to initiation of final <br />reclamation of the last part of Phase I. Please include details such as the maximum highwall <br />height and length in each phase, pit floor area exposed, area affected by processinglfacilities <br />area, etc. <br />14.The application mentions that the size of the buffer zones will be evaluated during the course <br />of the operation. Please be aware that any adjustment to the size or location of the buffer <br />zones will require a revision to the permit, submitted in the form of a technical revision or <br />amendment. <br />
