Page 2 <br /> layout of the contaminated material stockpiles and the <br /> plants relative to the property lines. <br /> SITE HISTORY: In June of 1987, a 5, 000 gallon gasoline tank <br /> and a 10, 000 gallon diesel tank were removed. In June of <br /> 1988, a 500 gallon waste oil tank was removed. <br /> In April and July 1991, excavation was performed to <br /> remove all <br /> potentially contaminated material and the spoil was <br /> stockpiled adjacent to the excavation. The excavation was <br /> subsequently backfilled. The stockpile from the removal of <br /> the waste oil tank contains approximately <br /> 800 CY and the stockpile from the removal of the gasoline <br /> and diesel tanks contains approximately 1, 200 CY. <br /> PROPOSED DISPOSAL: The Claude C. Wood Co. proposes that the <br /> contaminated material be processed by screening and crushing <br /> into mineral aggregates which would then further be <br /> processed into asphaltic concrete. Details of the plan are <br /> as follows: <br /> 1. The material will be transferred to the on site <br /> mineral aggregate plant approximately 1000 ft. by trucks or <br /> a front end loader. The two stockpiles will be combined to <br /> form one pile near the dozer trap feeder at the mineral <br /> aggregate plant. No other material will be <br /> combined with the contaminated material to be processed. <br /> The stockpile area at the dozer feed trap is hard and level <br /> gravel which will insure that all material will be picked up <br /> and processed thru the plant. <br /> 2 . The material, which consists of sand and rock, will <br /> be processed thru the mineral aggregate plant. (See Plate <br /> IV) This is a dry process with water only being used as a <br /> spray to control dust. The sand is separated from the rock <br /> at the 6x16 screen. The sand then travels via a conveyor <br /> out to a stockpile. The rock is sent thru the crusher and <br /> over the 5x16 screen. The rock is crushed and sized into 3 <br /> classifications, material finer than 1/411 , 1/4" to 1/211 , and <br /> 1/2" to 3/411 . The 5x16 screen discharges material onto <br /> conveyors which transport material to the proper stockpile. <br /> The mineral aggregate plant is a closed loop system, ie. all <br /> material going into the plant is discharged into a product <br /> stockpile. There is no waste. <br />
