.' a• -6- 9) Exhibit 16 - Drainage Control This section should be updated to include any modifications instituted since permit approval. The proposed changes in the system we have recently discussed must be submitted as a technical revision. This revision should be formatted with the appropriate page numbers. 10) Exhibit 17 - Bond There are no bond calculations included in Exhibit 17. The final, approved bond figures should be inserted here. IV. Maps a) The appropriate maps should be updated to include new facilities and the RDA. The Division feels that at a minimum Maps 8, 9, 12, 13, and 14 need to be revised in this manner. At the time of permit renewal, all maps will need to be current. b) Map 12a should be revised to show the (proposed) haul road, roads to the RDA, and roads to the prep plant area. An alternative would be to substitute maps from Stipulation 28, providing that.the stipulation can be satisfied. WFC must make sure that all roads used on the property are depicted on whatever map is use Also, due to the frequency and type of use, the Division feels that the E-W road extending to the non-coat waste disposai area should be classified as an access road. Roads leading to the prep plant should also be access roads. c) As we have previously discussed, Maps 13 A-C have been found to be inaccurate. All new facilities must be added to the maps. Drainage ditches must match up from map to map, and all ditches must have a discharge point. The ditch numbering system should also be consistent. It is suggested that diversion ditches be marked 1-D, 2-D, etc., and collection ditches be numbered 1-C, 2-C, etc. Culvert numbering should match the ditch system. For example, if there were two culverts on ditch 2-D, they could be numbered 2-D-1 and 2-D-2, or some equivalent. All approved small area exemptions should also be depicted in these maps. Specific recommendations are as follows: 13A-All culverts and ditches existing in the field need to be depicted. The non-coal waste disposal area should be included. 136-WFC needs to field check culvert sizes and include the correct sizes on this map. If any sizes are different, calculations should be revised so that the permit reflects actual conditions. Ail lay down areas should be indicated.
