August 2002 -30- 003 -2203 <br />On Wednesday, June 26, an Ames D6M Dozer damaged the Phase IVa geomembrane at panel <br />41 P -132. The dozer was stopped and the extent of the damage was identified (approximately <br />3 feet by 1 feet) by Golder. Ames exposed geomembrane in areas with less than 24 inches of <br />DCF for Golder observation. On the same day, Golder observed and documented the <br />geomembrane repairs performed by Poly -Flex. <br />On Wednesday August 21, an Ames Dozer ran over a grade stake damaging the Phase IVa <br />geomembrane at panels P- 463/465 approximately 55 feet from the Phase /IVa tie -in. Ames <br />exposed geomembrane in the area of the grade stake for Golder observation. On August 27, <br />Golder observed and documented the geomembrane repairs performed by Poly -Flex. <br />On Saturday August 24, an Ames 777 haul truck traveled on less than 10 feet of DCF in Phase <br />IVa during DCF placement. The truck was stopped and the extent of the area requiring DCF <br />removal was identified (approximately 2 feet by 12 feet) by Golder. On Monday August 26, <br />Ames exposed geomembrane for Golder observation. No geomembrane damage was observed <br />and the DCF was replaced according to specifications. <br />4.2.8 Temperature Monitoring <br />Golder monitored ambient air temperatures using a HOBO Pro Series data logging <br />thermometer. Temperatures were measured every 30 minutes. The lowest and highest daily <br />temperatures are summarized in Table 2. <br />During placement of SF, when the ambient air temperature was less than 32 °F for longer than <br />1 hour in the previous 24 hours, Golder was required to monitor the fill temperatures at depths <br />of 3 inches and 6 inches, at a frequency of 6 tests per acre, and calculate the average fill <br />temperature from the lower temperature of the 3 -inch and 6 -inch tests. A summary of fill <br />temperature monitoring is presented in Table 2. <br />0 <br />1A00U201\0400tCcnRA 080210012M04M04740Mdoc Colder Associates <br />
