19. Table 23 indicates elevations for the Emergency Spillways for three ponds as well as <br /> elevations of the Crest of the Emergency Spillway. What is the difference? Are these not <br /> the same point? Is the higher value the elevation of the pond surface with the emergency <br /> spillway flowing at the design depth? Please clarify and correct if necessary. <br /> 20. The as-built certification for the RDA pond was located in Exhibit 20 of the permit. The <br /> Division cannot located the as-built certifications for ponds 4, 5 and 6. Please submit <br /> copies of the as-built certifications for these ponds. <br /> 21. The currently approved permit lacks the information required by Rule 2.05.3(8) for the <br /> development waste pile located west of the main entrance. Both the text narrative and the <br /> information in Exhibit 30 is inadequate. Please review this Rule and submit the <br /> information as required. Also, part (9) of this Rule is "return of coal mine waste to <br /> abandoned workings, not (10) as presently represented in the permit. <br /> 22. Review of the approved post-mining contour maps indicates that restoration of the <br /> numerous drainages across the reclaimed areas has not been appropriately handled. Post- <br /> mining contour maps are required for all disturbed areas, including the water tank area <br /> and the Apache Canyon air shafts. Please submit post-mining contour maps for these <br /> areas at a 2 foot contour interval. Cross-sections should be at the same scale to allow <br /> overlay for volumetric calculations required for earth moving calculations. <br /> 23. The present plan for redistribution of topsoil does not clearly present the areas that will <br /> be topsoiled as opposed to those areas that will not have topsoil re-applied. Additionally, <br /> the topsoil pile east of the main entrance is represented as having a volume of 6,888 cy. <br /> Division field measurements indicate a volume closer to 16,000 cy. The plan for <br /> redistribution of topsoil should be clearly represented in the permit to indicate stockpile <br /> volumes, location, and discrete identification by name or code. All disturbed areas that <br /> are to be reclaimed should be delineated on a map, clearly showing acreages and depths <br /> of re-distribution, if it is an area to receive topsoil. <br /> 24. The permit text on page 2.05-51(b) refers to "test plot" production will be compared to <br /> reference area production. What test plot does this refer to`? Does Basin mean reclaimed <br /> area production will be compared to reference area production? Basin Resources needs <br /> to clarify what will be compared and correct permit text as necessary. <br /> 25. The permit text on page 2.05-51(b) refers to Cropland postmining land-use. This does not <br /> fit with approved postmining land-uses of rangeland and wildlife habitat. Permit text <br /> should be corrected or clarified concerning this reference to a cropland post-mining land <br /> use. <br /> 26. Permit page 2.05-51(e), revised April 15, 1994, states that "The sample will be deemed <br /> -9- <br />
