.-e" ~ :; ~~ Mr. Jay Lucas Februazy 2Z, 1982 Page 2 that are bazren after reclamation. It may also be possible to use some of thce fines from the wash plant sediment for growth media if and when they become available. These provide reasonably good growth medium and have been used at the Vazra Companies Carr Pit in the past. Exhibit E -Reclamation (2.) The seeding rate and proposed seed mix is, in fact, the same as that approved for the former Gravel Plant #3 permit. This application is for an amendment to the prior permit applications for Gravel Plant #3, which have previously included a 111 and a Succession of Operator under the same file number. There has been one minor amendment to the seeding mixture; that being the reduction of the Yellow Sweetclover seeding rate. The seeding mixture schedule, Table III, is attached hereto. Exhibit L -Reclamation Costs Based on our discussion in your office on February 19, I would submit the following as more appropriate reclamation costs given the operation as anticipated. As you know, initially all 40 acres will not be disturbed. In order to allow for the rapid development of the entire 40 acres, we would prefer to have you consider the disturbed acreage to be the full 40 acres and would submit the following as a working plan for that acreage. Approximately 5 acres of the site would lie the most that would be in the major disturbance category in any one time. For that major disturbance azea, we would anticipate a bond of $530/acre, to include $300 ;for grading and shaping, $110 for soil prepazation, and $120 for seeding. We would further anticipate that there would be 5 acres of moderate disturbance which had been graded ~md shaped, requiring only soil preparation and seeding for a total of $230/acre. Finally, the remaining 30 acres would be minor disturbance. Minor disturbance would include the graded area of the plant site, which, because of compaction, may need to ripped or scazified prior to seeding, some acreage which had been seeded but on which a reasonable stand of vegetation had not been established and some disturbed acreage. At any one time during the operation, approximately half of the minor disturbed azea would either be yet undisturbed or completely reclaimed while the other half of the minor disturbed azea would not have been ripped or seeded. Therefore we would anticipate an allowance of approximately $150/acre for ripping, scarifing and seeding 15 acres and $60/acre reflecting a 50% vegetation success rate or yet undisturbed status on the remaining 15 acres. Further, we would anticipate that of the 15 acres, approximately 30% may need to be mulched, either by hydromulching or with straw on pazticulazly erosion prone azeas at a cost of $430/acre.
