reopened, others remain plugged and consideration is <br />being given to simply replacing them. Unfortunately, <br />replacement of the culverts will require closing the <br />quarry as the access road will need to be excavated, <br />the pipe replaced, and then the road rebuilt. At <br />present it is being determined whether the existing <br />culverts can, in fact, carry the load so replacement <br />is not needed. <br />Repair of the slump will not be done until the <br />drainage system is fully operational again and the <br />source of the problem at the processing plant can be <br />fully addressed. The drainage system, although not <br />fully functional, still retains all the sediment it <br />was designed to retain. This is accomplished by <br />diverting runoff into other pathways that still lead <br />to the final discharge treatment outfall. However, <br />those diversions cannot be permanent. <br />Reclamation <br />(Wording same as 1998 report): Reclamation during the past year <br />has concentrated on revegetation work on the new mining areas. <br />If the reclamation area on Map 2 is compared with the Mining <br />area on Map 1 the considerable overlap is evident. This is the <br />result of using the new approach to reclamation of benches, that <br />is, immediate backfilling and topsoiling of benches as they are <br />completed. Although, as expected, bench collapse is still <br />occurring, the effects of those events on reclamation are <br />minimal. This is because the ingredients for reclamation are <br />already in place when the collapse occurs and repair occurs <br />rapidly. In effect, the progress of the reclamation and the <br />quality of that reclamation is very nearly as expected and <br />described in the last amendment for this operation. <br />A total of 6.6 acres of reclamation was done at this quarry in <br />the last year, about the same amount as was done in the previous <br />year. A11 of this involved reclamation of actual quarried land <br />rather than land in the support area as has occurred in the <br />past. As benches are completed, fill and soil is placed on the <br />benches. Late in the permit year the CMRF planted Douglas Fir <br />seedlings throughout the newly reclaimed area except on the <br />benches. Nearly all of the seedlings planted in the last year <br />were part of the Enhanced Reclamation with only a very small <br />number attributable to requirements under Base Reclamation. <br />Seeding of the newly reclaimed land occurred just prior to tree <br />planting to avoid adverse impacts of trampling on seedlings and <br />to allow trampling to further bury the seed. <br />Castle Concrete 2002 Annual Report M-77-211 Pikeview Quarry Page 5 of 7 <br />
