Response: Colowyo has added text to the current permit Volume 1, Section 4.14. relating <br />to the backfilling and grading operations within the East Pit which follow the plan put forth on <br />Map 29. Colowyo has attached two copies of the updated material for the Division's <br />incorporation into the permit. <br />3. The reclamation Colowyo has proposed for the East Pit from 2009-2017 will <br />be in the area of the Final East Pit Ditch (as shown on Map 41 - Watershed <br />Boundaries for Hydrologic Modeling). Please describe how Colowyo will <br />construct this ditch during reclamation and ensure its stability and ability to <br />safely pass the designated storm event while the areas above it are not <br />reclaimed. <br />Response: Colowyo will construct the Final East Pit Ditch using dozers and dozers <br />assisting a dragline. As reclamation of the East Pit progresses from east to west, all non- <br />reclaimed areas will be contained so that any residual runoff from these areas will be <br />isolated within the remainder of the East Pit. Internal sumps, internal ditches, contour <br />ditches and contour furrows will be utilized when necessary to allow the East Pit Ditch to <br />safely pass all designated storm events. <br />4. There is an area that is shown on the revised Map 29 that shows "Topsoil <br />Pile and Haul Road". Please add a timeframe for the reclamation of this area <br />and describe its reclamation in the permit text in Section 4.14. <br />Response: This area will not be reclaimed until at least 2017 since Topsoil Pile 16A will <br />most likely not be exhausted until this time or later. Furthermore, this area is in close <br />proximity to the West Pit and will most likely be a tie-in point for the East and West pits. <br />Colowyo has added text to the current permit Volume 1, Section 4.14. relating to this area <br />of question and has enclosed two copies of text for the Division's incorporation into the <br />permit. <br />5. The Division would like to remind Colowyo that all areas that are backfilled <br />and rough graded must be shown on an appropriate map and submitted with <br />the yearly Annual Reclamation Report, due no later than 1 April of the <br />following reclamation year. <br />Response: Colowyo is aware of the fact that all areas that are backfilled and rough graded <br />must be shown on the appropriate map and submitted with the yearly Annual Reclamation <br />Report which is due no later than 1 April of the following reclamation year. All areas that will <br />be backfilled and rough graded during the 2009 year will be shown on the appropriate map <br />and submitted with the yearly ARR which is due no later than 1 April 2010.
