August 2002 -29- 003-2203 • total of 27 out of the 120 nucleaz density tests failed to meet specifications. These azeas were reworked, recompacted, and retested to meet specifications. The number of retests was not used to determine the testing frequency. Holes made in the SLF during testing were filled by tamping SLF into the holes. 4.2.b.3 Depth Verification Ames drilled at total of 66 holes in the compacted SLF to verify that the minimum 12-inch compacted depth had been achieved. Golder monitored the SLF depth verification tests and documented results. Depth verification holes were filled with bentonite chips and water. All of the 66 holes drilled into the SLF had compacted depths greater than 12 inches. The testing frequency met the minimum specified testing frequency of two measurements per acre. The Soil Liner depth verification results are presented in Table 14. I . 4.2.7 Drain Cover Fill Golder provided visual monitoring of DCF placement. One Golder monitor and at least two Ames laborers were present monitoring each dozer, unless two dozers were within approximately 50 feet of each other during DCF placement. Golder verified that wrinkles in the geomembrane did not fold over, that PVC grade mazkers were placed on a maximum 50-foot by 50-foot grid and at grade breaks, and that unsuitable material was not present in the fill. Golder continuously inspected geomembrane during DCF placement, and marked azeas for repair if required. After fmal grading, Golder monitored removal of PVC grade markers. On Wednesday, June 19, an Ames D9R Dozer damaged the Phase fVa geomembrane at panel P-67. The dozer was stopped and the extent of the damage was identified (approximately 12 feet by 12 feet) by Golder. Ames exposed geomembrane in areas with less than 24 inches of DCF for Golder observation. On the same day, Golder observed and documented the geomembrane repairs performed by Poly-Flex. • i~oovzo3~oaoo~cmnevosoz~oo3zzononoo.oa~aou~ao< GolderAssoCiofes
