• ditches will be added where appropriate. All existing roads to be used during <br />the exploration program will be left in the condition that is superior to their <br />pre-exploration condition. <br />Any drill sites that are no longer needed for exploration or environmental <br />monitoring (such as piezometer wells) will be returned to their approximate <br />original contour promptly after all coal exploration activities are completed. <br />Topsoil will be removed prior to construction of any drill site when necessary. <br />After the site is recontoured, topsoil will be redistributed over the surface in <br />a manner that will provide for successful reclamation. If any exploration <br />drilling is to be conducted in an area directly ahead of the mining operations <br />where topsoil has been removed, the site will be mined through and reclaimed in <br />accordance with Section 2.05.4. <br />Revegetation of drill sites and roads will be performed by drill or by broadcast <br />seeding with a variety of native and introduced species during the late fall or. <br />early spring to produce a satisfactory vegetative cover capable of stabilizing <br />the soil surface. The affected areas will be seeded according to the mixture <br />described in Section 2.02. <br />in no case will any ephemeral, intermittent or perennial stream be diverted <br />during the exploration activities. Overland flow will be diverted, if necessary, <br />so that erosion ie controlled by ditches, water bars, sedimentation ponds or <br />other methods capable of controlling erosion and minimizing additional <br />contributions of suspended solids in the stream flow outside the exploration <br />area. Such diversions will be done in a manner that complies with all other <br />• applicable Federal and State requirements. <br />Upon completion of the hole, cuttings from the drill hole will be placed in the <br />drill hole and the site reclaimed. Some holes may be left open and completed <br />with piezometers, if they are needed for ground water monitoring. The <br />requirements of Section a.07 will be met for each exploration hole. See Section <br />2.04.4, Sealing of Exploration and Mine Holes, for further information in regard <br />to reclamation of exploration holes. <br />with the exception of possible piezometers to be installed in some of the drill <br />holes for groundwater quality and quantity monitoring, all equipment related to <br />the exploration program will be removed from the exploration area when it is no <br />longer needed for exploration. <br />During the exploration program, minimization of surface disturbance and prompt <br />reclamation practices will be utilized to eliminate sedimentation problems and <br />any disturbance of the present hydro- logic balance. Water bare and ditches will <br />be built wherever needed. Also, water from drilling operations will be contained <br />on the drill Bite and allowed to evaporate thus eliminating any off-site <br />disturbance. <br />Ae discussed under Section 2.04.6, no acid-forming materials have been found to <br />exist within the mine plan or adjacent area. <br />A compilation of 19s9-1997 Permit Area Coal Resource <br />Confirmation/Exploration/Monitor wells and Transfer of Permit Area Exploration <br />Liability to NOI-X-95-109-OS statue can be found in Exhibit 6, Geological <br />• <br />4.21-~ <br />Hevisbn Submitted I - ~ 3 - ' ~ <br />Revisbn No. TR -sy <br />
