RULE 2 PERMITS <br />3. Drill holes with no water or coal zones may be plugged by backfilling with cuttings, and placing a <br />plug ten feet below the ground surface to support a cement plug or bentonite chips to within 3 feet <br />of the ground surface. <br />For safety considerations, exploration drill holes that will eventually be mined through during the present <br />Permit term need only be covered with wood, plastic or other such material or otherwise bermed to <br />prevent access. <br />Those holes completed in aquifers will be sealed entirely with cement or other suitable sealant to within 3 <br />feet of the ground surface. <br />Where possible, the sealed holes will be marked. At times reclamation operations will cover up the sealed <br />drill holes and marking of holes will not be possible. <br />Within 60 days of the abandonment of a drill hole, approved drilling program or when requested by the <br />Division, the following information will be submitted: <br />a) Location of drill hole as plotted accurately on a topographic map. <br />b) Depth of drill hole. <br />c) Surface elevation of drill hole. <br />d) Intervals where water was encountered during drilling activities. <br />e) Diameter of drill hole <br />f) Type of amount of cement or other sealant used. <br />g) Name of drilling contractor and license number of rig. <br />h) How the hole was worked. <br />Exploration taking place inside and outside of the permit area will be handled through the Notice of Intent <br />(NOI) procedures. See the appropriate NOI for details for each program. <br />With the approval of Technical revision 50, all exploration holes located within the permit boundary are <br />transferred to NOI X-95-109-5 and are managed under Coal Exploration procedures. <br />Wells drilled as an integral part of water monitoring pland identified in the PAP (Permit C-81-019) and <br />water supply wells (for mining purposes) are managed under this Permit C-81-019. <br />Water and Air Quality Control Techniques <br />Steps to be taken to comply with the Clean Water Act and other applicable water quality laws and <br />regulations and health and safety standards include a comprehensive drainage and sediment control plan <br />described in Section 2.05.3 and Sections 4.05.1 through 4.05.18.
