ASPHALT SPECIALTIES CO. Exhibit D -Mining Plan ASCI is submitting this amendment to the current CDMG 112 Permit, Speer Mining Resource, to gain approval for the following uses to be amended into the permit and onto the Mine and Reclamation Plan Maps: • Sand and gravel mining and ^ Reclamation to a water storage reservoir with attendant wetlands and wildlife habitat Exhibit B, the Index Map, shows the general location of both the current permit azea and the area to be amended into the permit. Exhibit C-2, the amended Mine Plan Map and Exhibit F, the amended Reclamation Plan Map, both show the location of these uses. The Mine Plan Map also shows the currently approved locations of the both the aggregate plant site and the recycle plant site. The amended Mine Plan Map shows the Areas of sand and gravel mining for the entire site, as well as the initial and final location of the processing plant. The Areas are numbered in the general sequence of mining that will be accomplished (1 through 4), although mining and reclamation activities will progress concurrently and both mining and reclamation can occur in more than one azea simultaneously. The amended Reclamation Plan Map (Exhibit F) shows the final configuration of the water storage reservoir. MINING PLAN Overview ASCI proposes to develop the amended area for sand and gravel mining by the "dry- mining" method with virgin ("pit-run") material to be either conveyed or hauled to the currently existing and approved processing plant. Sand and gravel will be processed, stockpiled and loaded-out for use as concrete aggregate. Shipping via over-the-road transport trucks will occur as approved with the current conditional use through Adams County. No increase in production of aggregate or increase in the amount of trucks entering or leaving the site is being proposed. Onsite batching of concrete, as currently allowed under the existing Adams County conditional use, will also occur. The total amendment azea is approximately 15.2 acres out of which 11.4 acres is proposed for dry mining. Approximately 41.5 acres of the total permit area acreage, including the amended azea of approximately 67.5 acres, is proposed for mining. As previously appro~+ed in the State CDMG Permit, a 6.2-acre azea (revised Area 2) on a lower bench near to the South Platte River, is designed for wet mining and backfill to grade during the low-flow season of the river. After mining is complete, the main excavated azea will be reclaimed as awater-storage reservoir surrounded by a compacted clay liner that will be constructed in phases, during the reclamation operations. The edges of the reservoir will Speer Mining Resource 9 October 7, 2002 Asphalt Specialties Company, Inc. DMG Pcrmit Amendment No. 2
