Michael Boulay May 21. 2008 <br />series of properly sized temporary collection/diversion ditches that would be <br />replaced or extended as waste pile elevation increases. <br />Please amend the coal mine waste disposal sections of the application to <br />address measures that will be taken to ensure compliance with applicable <br />surface drainage requirements during pile construction, in addition to the <br />design information presented for the final configuration. <br />CAM: Figure 2.2-3, Section D-D', was amended to note the appropriate grading <br />of the pile during the construction phases. Text was added to the second <br />paragraph of Page 2-27ii the address the measures that shall be taken. <br />Rule 2.05.3(5) and 2.05.4(2)(d) Topsoil and Subsoil Removal, Storage, and <br />Redistribution <br />36. DRMS: Sections of the reclamation plan addressing topsoil and subsoil <br />(refuse cover soil) removal, storage, and replacement (Permit Sections 3.2 and <br />3.3) were not amended to address TR-16 proposed disturbances. <br />Please provide amended permit Sections 3.2 and 3.3 to incorporate TR-16 <br />proposed disturbances. The amended sections will need to address all <br />requirements of Rules 2.05.3(5), 2.05.4(2)(d), and 4.06, as well as Rule <br />4.10.4(5) (regarding quantity and quality of material to be segregated from <br />topsoil during salvage operations and separately stockpiled for non-toxic <br />coal mine waste cover fill). Revised salvage and replacement plans will <br />need to reflect quantity of suitable topsoil material available in the existing <br />stockpile, as well as suitable topsoil available from currently undisturbed <br />soil map units that will be salvaged in association with TR-16 <br />implementation. Similarly, the projected cover fill volume will need to take <br />into account any suitable material that will remain from the existing <br />construction material stockpile or that is currently in place beneath the <br />existing topsoil and construction material stockpiles, as well as suitable <br />subsoil within map units not previously disturbed, which will be disturbed <br />in association with TR-16 implementation. The topsoil stockpile and <br />sediment pond proposed in TR-16 would appear to fall within the boundary <br />of the East Salt Creek alluvial valley floor (AVF). As such, the paragraph on <br />page 3-8 noting that the office area is within the AVF would need to be <br />expanded to note that the topsoil stockpile and sediment pond are also <br />located within an AVF. <br />CAM: Please see amended pages 3-7 & 8. <br />37. DRMS: In Section 2.2.31 of the amended application, it is stated that "the <br />goal is to salvage approximately 7,500 CY [of subsoil] from excavating the <br />foundation of the [coal mine waste] pile for placement and storage in the coverfill <br />pile to ensure there is adequate material for final reclamation. <br />15
