King Coal Mine (C-1981-035) TR -20 Adequacy Review #3 Response <br />DRMS Oct 2015: Item regarding description is resolved. <br />DRMS Oct 2015 (New): It is difficult on Map King 1 007 to understand the relationship of the Refuse final <br />contour to the open drainage ditches. Please clarify the drawing so that this relationship is more <br />apparent. <br />The line indicating various reaches is very fine on the map. Please indicate on the map the overland <br />diversion structures and reaches in a line weight that is comparable to that indicated in the legend for <br />Map 007. <br />Map King 1-016 shows refuse coming up against the disturbed boundary. <br />Please clarify what areas on the map will be composed of refuse. <br />Pease explain what mechanisms for overland diversion will be implemented on the south edge of the <br />refuse pile. <br />For the crosssection (Map 016A) please make all text (and especially that on the vertical and horizontal <br />scale) a legible size. <br />Also, please indicate on the map the overland diversion structure in a line weight that is comparable to <br />that indicated in the legend for "open drainage ditch". <br />Adequacy Review 2A (Supplemental Response) Roof, Floor, Interburden and Coal Sampling: Proposed <br />Sampling Procedures <br />DRMS Oct 2015 (new): This document was reviewed as per Rules: <br />Rules that are or may be permanent to this issue are as follows <br />➢ 1.04 Definitions: (1a), (2), (139) and (140) <br />➢ 2.04.6 (3)(a) Geology Description Underground Mining (iii)(C)&(D); (iv)(D); and(v)(B) <br />➢ 4.05.1(4) Hydrologic Balance—General: (b)(vii) and (c)(iii) <br />➢ 4.05.8 Hydrologic Balance —Acid-forming and Toxic -forming Spoil <br />➢ 4.05.11 Ground Water Protection <br />➢ 4.14.1 Backfilling and Grading — General: (2)(f)(iv) <br />➢ 4.14.3 Backfilling and Grading -Covering Coal and Acid and Toxic -Forming Materials <br />Adequacy items as per the review of this document: <br />1. The plan provides very few specifics or justifications relevant to the King II mine. <br />Please provide a site specific plan. <br />2. Copper and Cadmium, listed in Table 3 of the DRMS guidance document are not listed in the <br />proposed chemical parameters and Methods of Analysis table provided by GCC. The Table <br />provided by GCC is a copy of Table 5 in the DRMS guidance document, which is "Overburden <br />Geochemistry — Suggested Methods of Analysis".
