ALBERT FRE! AND SONS, INC. <br />WORTHING SUBDIVISION <br />CASE # 5576-ZP <br />RECLAMATION PLAN <br />The intended final land use remains unchanged with the <br />exception that a small part of the site will become road right of <br />way. A single lake will remain so less reclamation work is <br />needed. There are no changes to the current revegetation plans <br />as approved. We plan to resoil the site above the proposed lake <br />elevation, use the approved seed mixture, and follow the rehabil- <br />itation methods as described in the approved plan. <br />The grade of the final slopes around the mined area with be <br />unchanged, they have a uniform slope of 3h to lv from 5 ft above <br />water to 10 feet below, below that they are 2h to lv. The <br />Reclamation Plan Map shows how the slopes will be configured <br />around the large lake. <br />As we noted in the Mining Plan text, part of the area will <br />be backfilled with on site material. The filled area shown on <br />the map will require an estimated 90,000 to 150,000+ cubic yards <br />of shale from the bottom of the lake. This will bring the fill <br />area up to the level needed by the highway authority. This area <br />will be reclaimed as the highway is built by MKK. <br />If, during the evaluation period after the lake is de- <br />watered, we find it feasible to construct the reservoir, we will <br />then make the following changes to the reclamation plan. The <br />grade of the final slopes around the mined area with be changed <br />so they have a uniform slope of 3h to lv. This slope rate will <br />reduce or eliminate chances of erosion on the slopes as the lake <br />level fluctuated during filling and draining. <br />If compacted fill is placed around the lake area to seal it <br />will be compacted to a 958 ratio. The compacted slopes will be <br />keyed into the bedrock so they will not slump. We do not know <br />the exact design criteria for the liner or what the volume and <br />maximum water level will be at this time, but this information <br />can be supplied when the engineering design work is completed if <br />the water storage project is feasible. <br />An eighteen-inch deep blanket of pit run material will be <br />placed on the shale slopes. This will buffer the softer shale <br />from the wave action due to wind. This blanket will also stop or <br />reduce erosion on the slopes as the water level fluctuates during <br />filling and water release. It will reduce the slippery condi- <br />tions normally associated with wet shale surfaces and provide <br />added safety if remedial maintenance work is necessary in the <br />reservoir. This blanket will run around the exterior of the <br />excavated from 10 feet out from the bottom of the slope to a <br />point approximately 3 feet above the maximum fill level. The <br />hatched area on the map shows approximately where this blanket <br />will overlay the slopes. if a slurry wall is installed of <br />compacted fill the slopes will be native gravel and the blanket <br />will be unnecessary. The floor of the lake will be left as <br />exposed shale and because it is a level surface of in-situ <br />material we do believe it has to be protected. <br />Reclamation will run concurrent with mining to keep the <br />amount of disturbed area to a minimum as required in the current <br />10 <br />
