• Page 3 March 6, 2002 Disposal of Crusher Fines and/or Waste Asphalt: Crusher fines are rekyded bads into other gravel pit products. As such none of these materials wiH be disposed of in the crushed fines form. The sbk (6) year history of the existing gravel piton the seahorse Ranch, Seahorse Pond Gravel Pit dermrtes that at no time have crushed fines had to be disposed of. Waste asphalt, all production of asphalt at this site shall be completed by an asphalt plant contractor. As a condition of the contract to produce asphalt at this site, all asphalt waste is to be hauled off the site and disposed of at and EPA and State of Cdorado approved site. No asphalt waste is stored at the gravel pit site. Containment of Hydrocarbons: Fuel (diesel) for the excavating and processing equipment is stored at the gravel pit site. Said fuel is stored in portable tanks of less then 5000 gallons. See drawing Exhibit "C for the location of the portable tank. The tank location is to irxiude an earthen containment arourxf the tank location. No other hydrocarbon materials are stored within the gravel pit site. Note, materials such as tube, hydraulic, dl, etc. are stored at the Ameripn Concrete and Gravel maintenance fadlity. Said facility is located just to the north of the Tomichi Creek, on Industrial Park road. Excavating the margin areas: The perimF-#er of each area is to be excavated to a depth of 10'-0" cresting a slope of 3.0 to 1.0. An access road to the center portion of area "B" is to be left for use by the equipment to complete excavating this area. Upon completion of excavating this arm, this access road will be excavated to a tlepth of 10'-0" with a 3.0 to 1.0 slope. Upon opening of area "A"the perimeter of this section will be excavated to a depth of 10'-0" creating a slope of 3.0 to 1.0. Two perimeter areas are to be exduded, along the existing Griffin # 1 Ditch and along the stockpile and equipmenUprooessirrg area. When opened the entire perirr~er of area "C" will be excavated to 10'-0" creating a slope of 3.0 to 1.0. As each of these perimeter areas are excavated and sloped, they are to t7e reclaimed as called for with in the reclamation plan. Perimeter Sloping, ling trenches. To address the concerns of reclamation should excavating of the areas interior stop after the perimeter areas are excavated. The inner side of the perimeter excavated arm shall be sloped to match the outer slope. This inner surface slope will be removed as the interior of this arm is excavated. 6kcavaTing interior areas. Excavating of the interior areas will resuR in slopes of 2.0 to 1.0 starting from the perimeter slope (10'-0" depth) to the bottom of the excavated area. The depth of the excavated area is determined by two factors. (1) maintaining a 2.0 to 1.0 slope and the width of the spedfic area. (2) if usable gravel and sand materials are found as the excavation process continues. The exception to this slope rule will be roads necessary to mwe material out of the e~ipvated areas. Said slope will be created upon dosing of such a road. Reclamation liability, acreage effected. During the first phase of the excavating process, approximately 9 acres will be effected. The area "B" is to be excavated during this phase. Approximatey 6 aces on the south side of the Old Railroad Grade Read is to be used for processing, stockpiling and equipment parking. During the second phase the entire 12.10 acres of area "A" and 1.5 acres of area "B" will be effected. During the third phase the entire 24.65 saes of area "C", plus 6 acres of area "A and 1.5 acres of arm "B"are effected. tt is to be rested that the 6 aces used in area "A" for stockpiling, processing and equipment parking will be excavated a5 the last phase of this project. During this time period all stockpiling, processing and equipment parking will be moved across the bridge to other American Concrete and Gravel owned property (off site).
