Map C-4 shows the detailed layout of the facilities area when the crusher and screen plant and <br />wash plants are located at the bottom of the pit. Since it is not known exactly what portable plants <br />will be brought to the site, the dimensions and locations of the plants are approximate. <br />The storage of fuel on site will be as follows: <br />a. Crusher and Screen Plant - there are a total of 6 separate tanks for diesel fuel, 2 <br />each @ 250 gallons, 2 each @ 500 gallons and 1 @ 600 gallons. This portable plant <br />has separate fuel tanks for each component of the plant: primary crusher with two <br />saddle tanks, 2 cone crushers and 2 screens. <br />b. Asphalt Plant -1 tank of 20,000 gallons capacity with two compartments, 1 of <br />15,000 gallons of burner fuel and the other of 5000 gallons of diesel as part of a <br />portable plant. <br />c. Ready Mix Plant -1 tank of 10,000 gallons diesel, as part of a portable plant. <br />d. Wash Plant -1 tank @ 3000 gallons as part of a portable plant. <br />The asphalt plant overspill and reject pile that is generated through normal operation will b treated <br />as component of the asphalt plant. When the asphalt plant is moved, the pile will either be moved <br />with it, or cleaned up and removed prior to creation of a new reject/overspill pile at the new plant <br />location. Additionally, in the event that the asphalt plant is removed from the mining pit floor to <br />prevent contact with ground water or flood water (see staff gage monitoring), then the <br />reject/overspill pile will be removed from the pit floor as well. Material from the reject/overspill <br />pile will be transported off site periodically to be recycled at the main portion of the Chambers Pit <br />north of the Colorado River. <br />This is the maximum storage for the fuel tanks on site. The loader would receive fuel from of one <br />of these tanks. If United does not move the portable asphalt or ready mix plants onto the site, there <br />will be a 1000 gallon tank for the loader only, which will be located near the office trailer outside <br />the 100 year floodplain. Secondary containment for this tank will be provided by installing the <br />tank inside a farm stock tank providing at least 110% of the tank volume <br />Scott Pit March 10 D-11
