• Also, because of the proximity to the mining operation, reclamation of the drill sites where mining is <br />imminent would be of no benefit and could not be achieved prior to mining because the area would be <br />redisturbed before vegetation could be established. Therefore, reclamation of these sites will not be <br />attempted until after the area has been mined and the ongoing reclamation operations are conducted for <br />the entire area. <br />3.3.2.2 Drill Sites-in Areas Where Topsoil Has Been Salvaged <br />Development drilling sites within the areas where topsoil has been salvaged in advance of mining activities <br />will not require special considerations for road construction or topsoil removal. These holes will be sealed <br />however, in accordance with Figure 3.3.1A or 3.3.1 B if they enter an aquifer. In all other instances, the top <br />of the holes will be plugged with drill cuttings. These sites will be reclaimed after mining as a part of the <br />normal reclamation work. <br />3.3.2.3 Areas not to be Drilled Within the Permit Boundary <br />To protect unleased federal coal resources within the permit boundary, development drilling will not be <br />conducted in these areas. An exploration permit will be obtained prior to drilling these areas. The areas <br />• that apply are: <br />a) No drilling below the "Q" coal seam under Lease C-25948, <br />b) No drilling in TSN, R91 W, 6th PM; Section 1, Lots 17,18,19. <br />c) No drilling in T6N, R90W, 6th PM, Section 30, Lots 15,16,17,18. <br />3.3.2.4 Suitable Materials for Abandoned Drill Holes <br />Suitable materials for drill hole abandonment in non-aquifer strata include cement, concrete, bentonite <br />products (quick gel, shur gel, or other appropriate bentonite chips, pellets, grouts or slurries), cuttings or <br />other appropriate materials. Suitable materials for drill hole abandonment in aquifers are cement or <br />concrete, or bentonite products if hole conditions are suitable for use of the product according to <br />manufacturer recommendations. <br />3-27 <br /> <br />AP., :- <br />A,ppjr;,OVED NOV p"'I9'a
