ALBERT FRET AND SONS, INC. WORTHING SUBDlVlSlON CASE # SS76-ZP the spillways and liner needed to develop the storage lake. Construction would begin shortly there after. If we determine the project is not feasible we will shut the pumps off after the gravel and shale have been removed and the lake will refill with ground water. No matter the final plan, the lake will hide the newly mined area below the lake surface. we will begin the operation by installing a pump in the northwest corner of the lake and pumping the water to the river. Once the floor is exposed, we will dig dewatering trenches around the perimeter and lower the pump to remove as much water from the excavation area. This will allow us to draw as much water as possible from the shale and make it Baser to remove. Mining will begin by removing as much gravel material as possible from the floor of the lake so the underlaying shale is exposed. During the trenching we will explore the floor to see if our suspicions are correct concerning the silt lens. Once the shale is exposed and has dried mining will begin by using scraping equipment to remove the material. If mining removes shale, it will go directly to the highway project and sand and gravel will be moved to the south area for processing. We will remove the dividers between the main lake and two eastern lakes leaving a single lake on the property controlled by Albert Frei and a small lake on the Tashiros' property. We will place fill along the west property line between the Frei and Yashiro parcels to create the smaller lake so the lake owned by the Tashiros' will not co-mingle with the Frei Lake. All the fill work will take place on Frei property with on site materi- als. We estimate this change in the mining plan will extend the life of the mining operation by 3 years, if our suspicions of a deep gravel lens are correct. MKK estimates it will take I.5 months to dewater the site, 3 months to dry the material and 3 months to remove it to their project area, so shale removal will end by late summer. If on the other hand, we find there is very little gravel left in the bottom we will complete mining and reclamation within 10 years. The existing slopes will be left undisturbed in the mined area, we will clean the floor, dress the slopes created by shale and gravel removal and let the lake fill with water. If we create the reservoir it will add 1 to 3 years to complete engineering and lining. There is no time limit on the mine life at this time and we prefer to leave it that way. 9
