The monitoring holes at each site will be spaced approximately 10-20 feet frgnm one <br />another The pilot hole site at each site will be plugged and reclaimed in accordance with <br />DRIv1S regulations. (See. Figure 2) After the hole is drilled to total depth, bentonite gel <br />will be pupnped clown the drill pipe to the surface and the hole will then be logged with <br />geophysical tools. When logging is complete, each pilot hole will be plugged by pouring <br />two 50 pound bags of 318' bentonite chips down the hole. Drill cuttings will f 11 the hole <br />to ten feet from the su.iface. The final ten feet will be filled with concrete and a survey <br />cap marking the hole will be set in the concrete at the surface. <br />Map 1 shows the proposed monitoring sites. Figure 1 shows the proposed method of <br />itiomfor hole construction. Figure 2 shows the method of plugging the three pilot holes <br />Table 1 is a list of the locations and estimated depths of the holes at each nest site <br />
