This information was collected over the period from December 7 through. December <br />9, 1993. <br />CONSTRUCTION ACTIVITIES <br />On the 5`" of December (Sunday) no work was done at the site. On December 8'' liner cover <br />material was placed, but no embankment material was placed, as BMRI workers did not haul <br />any material from the pit or borrow area. Weather conditions were dry and relat1vety warm <br />during construction activities. The construction activities during this period a{a outlined <br />below. <br />• Liner Cover <br />All of the liner cover material has been placed. All of the small (less than 1 acre) a(eas which <br />had not been covered at the end of the last work period have now been c•4ered with <br />sufficient material. <br />• Embankment Construction <br />At the end of this work period, approximately 80 percent of the 8803 (approximate elevation) <br />lift had been placed. The night shift on the 8`" was to finish placing this lift and place a <br />majority of the final lift (8605). As substantial borrow material of good quality remained at <br />the pit and there appeared to be no problems with achieving densities, I left the site for Fort <br />Collins on Wednesday night (the 8"'). <br />P _ 0 2 <br />• I <br />2629 Redwing Rd.
