An area immediately west of the Clark residence will be used as equipment parking and fuel storage. This area is approximately 10 feet higher in elevation than the present pit elevation and will be above the 100 year flood level. The fuel storage area will contain above ground tanks with containment pads large enough to hold more fuel than the tanks will hold when full. For instance, if two 500 gallon fuel tanks are used to store fuel, then a pad 10' X SO' with 2' high sides would be constructed using a neoprene double mat floor and side walls. This structure would hold approximately 1500 gallons of liquid fuel. Ground water will be encountered during gravel extraction operations. While the water will be disturbed by excavation, nothing will be added to the ground water. The ground water will not come into contact with the surface waters of the Animas River and will be allowed to settle out and filter back into the surrounding gravel bar. The processing area will be just north of the section of the pit being excavated. Processing will include crushing, screening to size, and washing. Washed gravel, rock, and sand will be the end product of this operation (3/4" to 1~/z" rock, masonry sand, 3" to 6" rock, and large rip rap materials will all be classified). No chemicals will be used in this process. Water from the pit will be used for washing and allowed to return to the pit and settling pond. Explosives are not expected to be used at this site. The Silverton-Middleton area experiences extreme winter weather conditions. Operations may be shut down for more than 180 days should an extended winter season occur. Some years operations will cease for 3 to 4 months while other years seasonal shut down could be longer. Most years stockpile removal will occur for 10 months with a 2 month freeze up shut down. The Clarks own the surface and the mineral rights to the affected land.
