-7- Fixed time - 1.1 minutes Haul time 0% resistance - 1 .45 min. Return time 6% resistance - 1.65 min. Cycle Time 4.2 min. A total of 3 scrapers can be loaded by one D9L. Therefore, 6. 5 hours would be required for this portion. A total of 1,300 CY of topsoil must be replaced on the bus garage ponds. The haul distance is 3,100 feet. A 637D scraper would have the following cycle time. Fixed time - 1.1 minutes Haul time 0% resistance - 1 .25 min. Return time 6% resistance - 1 .45 min. Cycle Time .8—min. A total of 3 scrapers can be loaded by one D9L. Therefore, 3.8 hours are required to complete this portion. The cost for topsoiling the portal area and sediment ponds is $9,998.00. Portal Sealing pJ C Mean' s Crew C-20 can pour 105 CY per day. The concrete plug required 56 cubic yards. Therefore, 4.25 hours are required to complete this job. At $2,061.00 per day, the total cost for installing the plug would be $1,100.00. Revegetati on C, 'i The reclamation plan requires seeding and mulching, plus fertilization if necessary. It is assumed that at least one application of nitrogen and phosphorus will be required. Also, it is assumed that the disturbed areas will be mulched at the rate of two tons per acre. The cost per acre is broken down as follows : Mulch 2 tons/acre @ $75.00/ton = $ 150.00 Mulch spreading @ 4 acres/day/person = 36.00 Fertilization = 40.00 Seed = 200.00 Hand Seeding = 30.00 Total Cost Per Acre $ 456.00 ;A total of 13.5 acres will be required to reclaimed. This figure is above that determined by Mid-Continent because a disturbance corridor of 75 feet was used rather than 50 feet. The total cost for revegetation would be $6, 156.00.
