3. As the rubble field in the middle of the failure gets more saturated we have experienced greater <br />movement. <br />4. The wait and see option may not be the best option. <br />In Exhibits 8 and 9 you can see the movement since the first of the year. There was a slight acceleration just <br />prior to the blast in February but as you can see there have been only slight increases in the movement. The <br />graphs in Exhibits 10 and 11 show the movement of the quarry with regard to the prisms located on the north <br />edge of the scarp and the rubble field below. As you can see the designated prisms, 21, 22, and 24 are <br />moving and this movement has accelerated in prism 20 until the boulder finally lost stability, rolled and the <br />prism was lost. Prism 21 was lost when a rock from above fell and moved the prism enough that it is not <br />able to be located by the monitoring equipment. However, prisms 22 and 24 are slowing in their movement <br />and prisms 19 and 25 along with 26, 27, 28, 29 and 30 shows only the noise of the instrument.. <br />In 1986 after a smaller slide occurred, the findings of MSHA were that the only way to ever stabilize the <br />limestone was to remove it from the face of the granite. The original layback; plan of 2000 was to <br />incorporate this idea within the reclamation plan to provide a more stable gradual slope at the end of the <br />mining activities. This will still be the ultimate goal of the amended reclamation plan <br />With that said, Castle Concrete would propose being allowed to go back into the Pikeview Quarry and <br />continue its investigative work. This work will include backfilling and compacting material in the north end <br />of Area H so as to better fortify the toe of the slide. Work would commence from the most stable north end <br />and proceed south to where the bench in Area H with an elevation of 7140 feet exists. It will also include <br />some blasting and removal of limestone from the face of the decomposed granite as well as for stabilization <br />of existing areas that continue to move. <br />Exhibit 13 shows the southern boundary of the work on the north end of the quarry. The southern end of the <br />7140 elevation bench is depicted by the red line. The shaded area at the toe of the north end in Exhibit 13 <br />shows the area to be backfilled to fortify the toe. This area would be backfill.ed to the elevation of between <br />7200 and 7225 which would match the existing production floor elevation to the east of Area H <br />During the investigative process Castle Concrete will also need to blast and remove some limestone to <br />determine the best mining practice for the south end of the quarry and to determine the stability of the granite <br />beneath the limestone. In all instances Castle Concrete would request that it be allowed to process the <br />material removed during the investigation to facilitate have a clean work area within the investigative area. <br />This pertains specifically to the north end of the quarry along with the south end where we will be <br />investigating the best way to remove the limestone from the slope once it is removed from the granite. <br />For safety purposes the area designated by numbers 21, 22, and 24 in Exhibit 12, and highlighted in yellow <br />at the top of Exhibit 13, needs to be stabilized through blasting as it continues to move. Likewise more <br />attempts at stabilizing the area referenced by the numbers 13, 15, and 18 in Exhibit 12 will be undertaken. <br />This will allow Castle to continue the needed analysis for preparation of the required amendment.
