King Coal Mine (C-1981-035) <br />TR -25 Adequacy Review 41 Response <br />4. The sediment cleanout level of 7229.25 ft. called out in the Executive Summary of Appendix 11 (1) <br />changed to 7231.67 ft. as per Map King II 007. Please update the Executive Summary to <br />reflect changes to: <br />a. Maximum sediment level and its acre feet of storage capacity <br />b. Sediment clean out level and associated acre feet of storage capacity. <br />These levels and capacities have been added to Map Kina II -007A. <br />S. Please address La Plata County concerns (letter enclosed) expressed in their 24 July <br />letter to DDRMS regarding: <br />a. Sediment removal from pond at 60 % of max level, (update executive summary) <br />b. Disposal and handling methods of sediment removed from pond. <br />Sediment removed from the pond is transported by truck to the refuse pile at the Kina I <br />mine site, spread and compacted in lifts not to exceed 24 inches. <br />Rule: 2.10 Maps and Plans <br />To adequately meet the requirements of this Rule please provide the following map updates. <br />Maps General <br />9. Regarding the three maps (007A, 0076 and 007C) provided with the application; please update <br />each of these maps to include the following information: <br />a. Call out the contour interval (e.g. Contour interval is 2'). <br />The contour interval has been added as reauested. <br />b. Scale: 1:1200 (or whatever it is). <br />10. Please explain why survey coordinate points are called out on the right side of each <br />map. I don't see these items located on the map <br />The survey coordinates shown have been removed; they were not relevant to these maps. <br />Map Kina II 007A <br />11. There is a great deal of visual information on this map. Generally a map should not have more <br />than 7 separate layers on it, more than that is too much information. To make it legible and <br />easier to use please make the following changes: <br />a. Please orient all text horizontal from left to right, eliminate upside down, sideways <br />etc. text. <br />Where practical, all text has been reoriented horizontally <br />b. All elevation values should read from left to right with map facing up. Maybe <br />offset them from each other a bit. <br />Elevation values, where practical, now read from riaht to left with the map facing up. <br />c. Make sure text is not obscured and under other layers <br />Text has been arranged so as to not be obscured under other layers. <br />d. Please remove the crosshatching for the basins, but keep outline colors for each <br />basin (maybe with a thick line, and do also keep the directional flow arrows). <br />The crosshatchina has been removed and the lines are thicker as requested. <br />e. Please indicate acreage for each basin (use one font color for all acreage, e.g. dark <br />blue), or on the map provide a table indicating each basins area. <br />Acreage has been indicated on the map in one font color. <br />f. Please remove symbology from the map that is not pertinent to the map (dots at <br />right edge of map, red line with x's, green curly que lines, etc.). This map focuses <br />on hydrology. <br />Symbology not pertinent to hydrology has been removed. <br />g. Symbolize any natural streams <br />Natural streams have been symbolized in the leaend. <br />
