17 November 1976 PONED-G Quarry, Rock Crushing, Screening and Central Mix Batch Plant Operations for Cleanup of Enewetok Atoll, M.I. b. Determine total volumes of coarse aggregate to be stockpiled. (5,400 c.y.)(1 + total correction factor) 3/4" to No. 4 (5,400 c.y.)(1 + 40%) c. 7,560 c.y. (stockpiled) The low yield for producing 3/4" to No. 4 size coarse agerepate shall dictate the quantity of material required for processing. Estimated quantity of material from borrow is: 7560 cy/23% USE 4, = = 32,870 cy 32,900 c.y. The approximate surface area dimensions for the aggregate borrow area using an average depth of 8 feet and width of 250 feet is: Length = USE (32,900 c.y.)(27 c.f/c.y.) (250 ft) (8 ft) = 444 €£t. 250 feet width x 450 feet length (within limits of proposed quarry site) F. sO REQUIRED AREA FOR CRUSHING, SCREENING AND WASHING OPERATIONS; AGGREGATE STOCKPILING, WASTE STOCKPILING 1. a Assuming the primary and secondary crushers are separate units and the screening and washing units are a common plant and all units are located in tandem and connected by conveyors, the area required for siting and conveyor off loading shall be approximately 110 feet wide x 250 feet long 2. 3. Stockpiling Coarse Aggregate: a. Quantity of 3/4" to No. 4 coarse aggregate stockpile equals approximately 7,560 c.y. b. Recommend providing a nearly rectangular shaped stockpile 100 feet wide x 150 feet long. Weight is approximately 10 feet clear and level 12 feet beyong the periphery. Stockpiling Fine (sand) Aggregate: a. Quantity of sand aggregate stockpile is approximately 6,600 c.y.
