This information was collected over the period from November 25 through <br />December 4, 1993. <br />1 CONSTRUCTION ACTIVITIES <br />During the period November 25 through 29 (Thanksgiving weekend and the Monday <br />following), very little was done on the embankment as BMRI's workers were off and the <br />borrow pit was being developed. During this period there was a substantial quantity of liner <br />' cover placed, as Southway's workers did not take any days off. <br />Weather conditions have generally been conducive to the construction activities. One dusting <br />of snow was experienced at the site on the morning of December 3. <br />The construction activities during this period are outlined below. <br />' • VLDPE Liner Repair <br />' All liner repairs were completed and tested during this work period. <br />• Liner Cover <br />' All liner cover material has been placed. Several small Iless than 1 acre) areas remain where <br />additional material must be placed to reach the 24 inch minimum cover thickness. This work <br />' will be completed on Monday and Tuesday of next week. <br />Consulting Engineers and Scientists <br />
