Mr. J it Herron January 26, 1983 Page 2 3. b. (continued) froam 12" to 18". This, multiplied by the areas, is as follows: 2-yr = 4 acres x 1.5' = 9680, cu. yds. 5-yr = 5 acres x 1.5' = 12,100. cu. yds. The topsoil storage area adjacent to the No. 4 mine truck-haul road will hold approximately 15,000 cu. yds. The access road and the two-year pile topsoil will be stored there. (See Sheet 4.) The five-year pile topsoil will be combined in this storage area (see Sheet 5) for a total of approximately 24,000 cu. yds. c. Revegetation Plan. When the 2-year pile is completed, the S.W. top section (2 acres) adjacent to the road will be topsoiled (12" to 18") and planted with the 10,0001 seed mix (enclosed subject to review by MLRD); approximately one ton of hay mulch will be used per acre. The seed will be broadcast and the mulch applied by hand in the fall (October), following completion of the pile. d. Time Table. The 5-year pile will overlay the base of the 2-year pile and the life-of-mine pile will overlay the 5-year pile (basically in five-year increments) . When the top section of the pile is completed (adjacent to No. 4 Mine road, estimated at 10 years) it will be revegetated following the same procedure as the 2-year pile. This sequence will continue: as five acres are added, five acres will be reclaimed, leaving at no time more than ten acres of waste exposed. e. Revegetation Success Criteria. As per MLRD letter from Jim Herron dated October 12, 1982, "the Division suggests that the woody plant density standards be set at 100 trees/acre and 500 shrubs per acre for each of the three major vegetation types. The herbaceous cover and production standards would then be the amount measured in the surrounding vegetation types." This will be the revegetation success standard for the new refuse pile. 4. LEGAL RIGHT TO ENTER The USFS has completed its special use permit for the area and it will be forthcoming shortly (due 2/l/83) .
