MEETING NOTES Page 4 May 7, 1999 • Protective Operations Layer—The protective operations layer will be"floated" out over the granular drainage material. The soil will be brought to the base and dumped on the edges and then pushed out over the granular drainage material with a dozer. "Fingers" of operations layer may be placed to allow access to the interior parts of the cell. • Vegetative Layer—Jeff said that he had some concerns with placing the vegetative layer on the Ash Pit since Guinn would not be constructing the subgrade fill. Sangeeeta said that if Vector is performing CQA and the subgrade fill is compacted to the required density that there shouldn't be issues with the competence of the foundation. Jeff felt that it might be difficult to place vegetative layer because the slope may not be uniform. Sangeeta said that the slope did not have to be a consistent 3.5:1 and that the requirement is only that 1.5 feet of soil be placed, which exceeds the regulatory requirement of 1-ft thickness. Tim felt that placement of the vegetative layer shouldn't be a problem. • Drainage Structures—No issues were noted. PROJECT OVERVIEW—OTHER ITEMS • Leachate Impoundment-Pete noted that moving of the monitoring well is still tied up with DTSC, so it is still not certain whether the leachate impoundment will be constructed this year. • WMU Interim F - If the leachate impoundment is not constructed, WMU Interim F would not be closed this year. • Access Road and Drainage Facilities -Jeff will work with Butch on developing a suitable access road and a revised price. • Bridge—Butch said that the permit had been received from the flood district, but obtaining a building permit from San Joaquin County was still in the works. Quaterolli is working with the bridge manufacturer to develop the design. It is not certain whether the bridge will be constructed as part of this year's construction. • WMU B Stockpile—Butch has removed much of the stockpile and the remainder will be used as daily cover for refuse to be placed on WMU B. ADMINISTRATIVE/CONTRACTUAL SUBMITTALS • Guinn has submitted their bid and the prices are still being negotiated. Once the bid prices are agreed upon, the Agreement will be signed. • Guinn should submit applications for payment to Scott. Scott will review the payment application and forward it to Allied.
