Of this, approximately 12.2 acres <br />will be ponds, approximately 9.4 acres adjacent to the ponds will require <br />reclamation, and approximately 3.9 acres will remain undisturbed. The <br />reclamation tasks to be performed are described in Exhibit E. <br />- Grade side slopes of ponds per plan. Approx. 25.1 cu. yd. <br />material to be moved/lin. ft. using D-9 with straight blade <br />(total = approx. 139,305 cu. yd.). Ave. moving distance of <br />75 ft. Approx. 801 cu. yd./hr. dozing production (est. <br />Cat. performance curves, includes various correction <br />factors). Approx. 174 hrs. required @ $180/hr. (monthly <br />rental, includes equipment, fuel, operator wage, etc.). 31,320 <br />- Misc. minor smooth grading of disturbed areas adjacent to <br />ponds using D-9 dozer. Est. 9.4 ac. to be graded. Est. <br />production rate of 1 ac./hr. Approx. 9.4 hrs. (say 10 hr.) <br />required @ $180/hr. (includes equipment rental, fuel, <br />operator, etc.). 1,800 <br />- Replace ave. 8 inches of soil on 9.4 ac. (10,111 cu. yd.) <br />using 21-31 cu. yd. scraper (eg. Cat. 637D) and D-9 dozer <br />Tasks proportioned at approx. SOX of effort for scraper <br />(used on all flat disturbed areas) and 50Z of effort for <br />dozer (used for dressing side slopes and areas of the ponds <br />above the water). Ave. haul distance for scraper = 600 ft. <br />Est. scraper production of 216 cu. yd./hr. (derived from Cat. <br />performance curves, includes correction factors). <br />Approx 24 hrs. required for scraper @ $300/hr. (includes <br />equipment rental, operator, fuel, etc.). For dozer, ave. <br />push distance of approx. 50 ft. Est. production of 850 <br />cu. yd./hr. (derived from Cat. performance curves, <br />includes correction factors). Approx. 6 hrs. required <br />@ $180/hr. (includes equipment rental, fuel, operator, etc.). 8,280 <br />- Seed bed preparation and application of fertilizer. Use <br />230 DBH 4WD farm tractor with disc attachment Approx. <br />3 ac./hr. production rate Total of approx. 3.1 hr. <br />(say 4 hr.) required @ $90/hr. (includes equipment and <br />operator). 360 <br /> <br />
