• °the most part, be limited to dry weather use. Additional steps to minimize surtace disturbance will include <br />burying, or removing from the site, all garbage and foreign debris. <br />Surtace and sub-surtace waters will be protected from contamination and the intermingling of water from <br />different aquifers will be prevented. Also, unless required for monitoring or as a water supply, artesian <br />flow will be prevented by appropriate sealing of the hole. Where necessary, small diversions will be used <br />to divert surface runoff around and away from the immediate drill site. Runoff from the drill sites will be <br />very small because of the small area involved and will not be passed through a sedimentation dam unless <br />it occurs in a drainage where a sedimentation dam has already been constructed. Any water generated <br />by the drilling operation, i.e, when drilling with water, will be contained in small pits and covered with at <br />least two feet of material or allowed to evaporate. <br />Water bearing drill holes located in areas where mining is not imminent (will not be mined within two <br />years) will be plugged according to Figure 3.3.1, 3,3.1A, 3.3.iB or 3.3.1C. Since all drill holes are <br />awurately located for mine purposes, an above-ground marker is not required. A marker will be installed <br />only if a survey has not yet been completed. Dry drill holes will be plugged with appropriate cuttings only. <br />These holes will be reGaimed as will any roads that are built to provide access and are no longer required. <br />Thls will incude returning the area to its approximate original contours, ripping or discing heavily wm- <br />pacted areas, replacing topsoil, and seeding with appropriate seed mixes (refer !o Section 3.6.3.5). <br />In instances where a drill hole is located on cropland, a steel rod or wooden marker will not be cemented <br />• into the drill hole collar. Since all drill holes are accurately located for mine activity purposes, an <br />above-ground marker is not required. In the event that the hole needs to be relocated at a later date, sur- <br />vey coordinates are available. The reclamation procedures as described eadier will be followed after the <br />drill hole has been sealed off. <br />Development drill holes located in areas where mining is imminent (will be mined within two years), and <br />that do not enter an aquifer below the lowest coal seam to be mined, will not be sealed according to Figure <br />3.3-1, 3.3.tA, or 3.3.1 B. However, drill cuttings will be placed into the holes to seal the opening at the <br />surface. This will prevent injury to man and wildlife. The proximity of the open pit and its imminent <br />advancement through the area minimizes any possible benefit of sealing such drill holes. <br />• 3-25 <br /> <br /> <br />
