<br /> <br />ACCESS: <br />Proposed drill holes are located near existing roads or in locations where <br />minimal damage will result from overland travel. If excessive damage occurs <br />to roads or vegetation as a result of travel to and from the site. the <br />affected areas will be reclaimed. Some minor improvement to existing roads <br />or trails may be required. <br />SITE PREPARATION: <br />All sites have been chosen to minimize site grading and leveling. The drill <br />rig will use self-contained leveling jacks to further minimize drill site <br />preparation. All drill sites will be located in open areas to further <br />minimize disturbance to vegetation. <br />TOPSOIL HANDLING: <br />Topsoil will be stripped from the area to be affected by drilling activities <br />• and will be stockpiled near the drill site. Top soil will be redistributed <br />over the disturbed area following cleanup of the drill site. <br />CONTAINMENT OF DRILLING FLUIDS: <br />The variation in geology and consequent changes in drilling conditions can <br />lead to field changes in the types of lubricants, soaps or fluids required <br />to complete the hole. Therefore, various methods may be utilized to contain <br />the fluids and cuttings on-site. These methods may include portable mud <br />pits, containment berms and/or excavated mud pits. In the event excavated <br />mud pits are utilized they will be constructed and operated in the following <br />general manner. <br />Two small (approximately 6'x8'x4') interconnecting pits will be excavated. <br />The first pit will serve as a settling basin for drill cuttings. Decanted <br />fluids will flow into the second pit from which the fluids will be <br />recirculated to the drill hole. Drill cutting and other debris will be <br />removed from the pit and hauled to Dorchester's refuse dump prior to <br />• backfilling. <br />-2- <br />
