B. Scott talked to Sangeeta about ballast for the pond bottom. Guinn will <br /> determine prices for placing about 1 foot of gravel on the bottom of the pond <br /> instead of the cement-lined tires. <br /> 2. Review of work progress since previous meeting: <br /> A. The berms have soil placed over them on the south slope of the ash pit and <br /> slope of the cells. <br /> B. The vegetative layer on the ash pit has been placed. The top still needs to be <br /> completed and the material track-walked in. <br /> C. The pond excavation has been on going. <br /> D. The gravel for the pond was delivered and Vector ran a sieve on it. <br /> E. All of the granular material was placed in the D-99 cell. Guinn is waiting for <br /> the geotextile to finish the cell. <br /> 3. Projected schedule: <br /> A. The primary excavation of the pond should be completed. <br /> B. Subgrade preparation should begin tomorrow. <br /> C. Kleinfelder is scheduled to begin placing the lysimeters on Thursday. This <br /> may change, however, since additional lysimeters will be placed. <br /> D. Depending on the amount of over-excavation needed, Guinn should be ready <br /> for GSE to line on the 16th. <br /> 4. Coordination of schedules: <br /> A. GSE has committed to begin lining on the 16th of August for the pond. <br /> B. The geotextile should arrive on-site with the HDPE by tomorrow afternoon. <br /> 5. Field observations, problems, conflicts, and changes: <br /> A. Forward will place the 20-inch CMP across the road on the south side of the <br /> ash pit. <br /> B. Guinn will provide a cost comparison for placing gravel on the bottom of the <br /> pond instead of using the tires. <br /> C. Guinn was instructed to place two additional lysimeters under the sump. The <br /> RWQCB stated that if the two proposed lysimeters failed, they would have to <br /> be replaced. Because of this, two back-up lysimeters will have to be installed. <br /> D. With GSE not showing up until the 16th, Guinn will have no problem surveying <br /> the final grades of the pond prior to placing liner. <br /> E. Along the anchor trench on the southwest side of the ash pit, no geotextile <br /> was placed for protection. Guinn will fix this problem by digging up the soil <br /> n:/98601 1.01 Meekly Progress Meetings/08-03-99 Meeting Tdoc Page 2 <br />
