<br />Proposed II 4-6 26.36 22.91
<br />`: The second revisiou,riead_pnly be considered if tTie change in the timetable is denied.
<br />We expect. to finish"9tage i,.¢uring the 1979-1x80 mining year. This is approximately
<br />F- one year, ahead of our e9tiima~ed timetable. We request the approved timetable be
<br />revised to.show Stage Y'as being mined from 1878-1980 rather than 1978-1981 and that
<br />Stage II.show mining from 1980-19$$ rather tfian 1982-1985. The reclamation phases
<br />then should be appYOpriately changed from 1982-T986 to 1981-1985 and 1986-1990 to
<br />1985-990. As 3ou.can see, if we continue to mine at this accelerated pace, we will
<br />saoa be amending these ~;,etiCious year estimates annually.
<br />The thud revision is a~.53.ight'ehattge in the procedure on approximately 1.26 acres
<br />k;,. in Phase 0. The east face~of the dike separating Stages .Y and O is the west bank
<br />of a nature lake that w%2t cover all o£ Stages 0; I and Ii. Originally it was
<br />planuet to backfill oven this rock slope and revegetate in 1979. Because of the
<br />backfilling and leveling going on in Stage Y, that is expected to continue for as
<br />long as 35 years, this small area in Stage 0 will be exposed to less than .{teal
<br />conditions for revegetatioa. .We watsld.like to leave this 1.26 acres in'ns'present
<br />
<br />configuration until Eha§e .Y is t+eii~<ievegetated. Revegetation of both areas in a ,~.'.~±
<br />single phase operation yiould be much easier for us to handle and will improve the
<br />Likelihood of successful revegetation on the first planting.
