i • EXHIBIT D A portable wash plant will brought in periodically to remove fines from material to be used in producing concrete. It will be located where most convenient within the permit area, as necessity and convenience dictate. However, it is likely to be used in the same manner and same location as with the existing operation. The wash out area is located on Exhibit I, Soils and Water Features Map, labeled as "truck wash". A portable crusher plant will be brought on-site a few months of each year to process and sort the sand and gravel. This will be located where most convenient, either on high ground or in the bottom of the pit. Section 3 -Water Diversions and Impoundments Water will be diverted from existing reservoirs for wash plant, batch plant, and dust control operations. This will be accomplished by simple pumping techniques and held in water trucks or tanks, using as needed. Runoff and wash water will be returned to the existing reservoirs or pumped into the Big Thompson River, subject to all considerations and terms of an NPDES permit to be acquired prior to start of mining activities. Dewatering operations will divert water from its natural location into existing reservoirs or the Big Thompson River. This will not create any adverse impacts; the historic destination of these waters is the Big Thompson River. Section 4 -Nature of Deposits and Overburden Bores were drilled on either side of St. Louis Avenue by Earth Engineering Consultants of Fort Collins. The Reichert property is undisturbed in the area to be mined. Topsoil is at an average depth of 6 inches. The average thickness of overburden in this area is 6.75 feet. The average thickness of the sand and gravel resource layer is 12 feet on this side. The nature of the stratum immediately beneath this layer is weathered claystone. The Flatiron property has a long history of disturbance, mining and industrial use. No topsoil is present on this side. The average overburden thickness in the area to be mined is 2.08 feet. The average thickness of the sand and gravel layer is 16.25 feet. The stratum beneath this layer is comprised of claystone. Sand and gravel mined from the areas collectively known as the Loveland Pit will be used as aggregate for the production of Portland cement concrete and asphaltic concrete. The consumer use of these materials include, but are not limited to roadway, parking area, structures, sidewalk, bike path and trail construction. Sand and gravel will be sold to private consumers and used as base course for road construction. No incidental products are expected to be mined or extracted from the proposed operation.
