..~~_ • ~ <br />The limestone waste pile has shown fair to good growth over most of <br />the face, even though the slope is close to the angle of repose. In a few <br />areas, the soil sloughed off the slope and this will need to be treated <br />somewhat differently in the future. However, it is apparent that at least <br />a temporary revegetation of fair to good cover can be established on this <br />steep slope, especially where the aspect is north to northeasterly. <br />All in all, nearly all of the revegetation projects to date have met <br />with at least fair success, and most with an outs[anding success. All of <br />the areas reclaimed to date, however, have been associated with <br />disturbances which do not include the quarry face itself. That will be <br />quite a different situation which will need to be approached in the future. <br />RULE 2.41 7 : ESTIMATES OF THE LOCATION AND NUMBER OF ACRES TO BE <br />AFFECTED IN THE COMING YEAR. <br />The number of acres to be affected in the next year cannot be <br />accurately determined as the aggregate market is extremely unstable. The <br />area delineated on the annual report map projects the extension of the <br />current mining area to include this area. Of course, as the quarry mining <br />area expands southward, land behind is completed with mining. Therefore <br />the amount of acreage actually involved in mining during any particular <br />year remains at a fairly constant level of between 8 and 16 acres. The <br />actual amount depends largely upon the configuration of the area where <br />mining is to occur. Certain configurations determined by the rock type, <br />dip, and relationship to other areas greatly determines how much land is <br />needed. <br />MAP: Attached is a map prepared on the newly acquired and installed <br />computer mapping system. All future annual report maps will be prepared on <br />these types of maps. The system permits not only 2-dimensional mapping to <br />great accuracy and precise scaling, but also permits 3-dimensional modeling <br />of topography which will be useful in designing reclamation and mining <br />plans for areas exhibiting rough topography. <br />Page 4 of 4 1988 PIKEVIEW QUARRY ANNUAL REPORT <br />
