.~; <br />RULE 2. 1 THE SPECIES OF VEGETATION PLANTED, THE LOCATIONS AND <br />APPROXIMATE DATES OF PLANTING. <br />No planting occurred at this operation in the last year. No land <br />was ready for planting by the time the planting season had been reached. <br />Planting of those areas which were ready shortly after the planting <br />season will be planted next October or November. <br />RULE 2. 1 THE TYPE AND APPROXIMATE QUANTITY OF FERTILIZERS, ORGANIC <br />MATERIAL, OR SOIL CONDITIONERS USED AND LOCATION OF USE. <br />No fertilizers or soil amendments were used in association with the <br />previous plantings at this quarry. <br />RULE 2. 1 6 AN APPRAISAL OF THE SIICCESS OF RECLAMATION EFFORTS, AND <br />IN THE EVENT OF FAILURE OF ANY EFFORTS, A SHORT NARRATIVE ON THE <br />SUSPECTED OR DETERMINED CAUSE OF SUCH FAILIIRE. <br />The old Peter Kiewit Stockpile area and the Tract WDT area have <br />shown that success with the seed mixtures we have used and will continue <br />using is quite good where soil is limited or absent and limestone waste <br />not present. A similar mixture was used on the access road sides with <br />similar success, even though the slope is very steep. But in the latter <br />case, the north aspect certainly has contributed to the success. <br />The shop slope has shown that sweetclover is important to <br />establishing a quick cover and helping the grasses to become <br />established. It also shows that slope stabilization is critical to the <br />success of any reclamation project. The instability which has developed <br />in the eastern quarter of this slope has been a severe aggravation and <br />appears to be alleviated through the construction of a support berm at <br />the base of the slope. The completion of the support berm will further <br />alleviate this problem allowing a regrading of the slope and replanting <br />of the area where the slumping damaged the slope. <br />The limestone waste pile has shown fair to good growth over most of <br />the face, even though the elope is close to the angle of repose. In a <br />few areas, the soil sloughed off the slope and this will need to be <br />treated somewhat differently in the future. However, it is apparent <br />that at least a temporary revegetation of fair to good cover can be <br />established on this steep slope, especially where the aspect is north to <br />northeasterly. <br />All in all, nearly all of the revegetation projects to date have <br />met with at least fair success, and most with an outstanding success. <br />All of 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 <br />future. <br />Page 3 of Q 1989 PIREVIEW QUARRY ANNUAL REPORT <br />
