[l <br />Timber -panel installation continued at the South MSE wall. <br />tl) Storm Water Management <br />Best Management Practices (BMP) is being performed. Erosion control efforts took place during this reporting <br />period following any precipitation (snow removal and runoff from melting snow and ice). Furthermore, Ames <br />cleaned out existing runoff containment sumps along the VLF haul roads and added three more sumps near the Rip <br />Rap processing area. <br />CQA ACTIVITIES: <br />I) Field Activities: Observation of construction activities during this reporting period included: Slope grading and fill <br />placement; Ambient and fill temperature monitoring and recording; Underground working remediation and drilling; <br />Production drilling and blasting; Timber panel and tailing removal at the historic Crib Wall; Timber panel installation at <br />the South MSE Wall; and Rip Rap, Clay Soil Liner Fill (SLF) and Drain Cover Fill (DCF) processing. <br />n) Laboratory Activities: Laboratory testing continued with Permeability, Particle Size Distribution, Atterberg Limits, <br />Moisture- Density, gradations, material classification, identifications, and field material sampling were performed during <br />this reporting period. <br />DCF Sample 54 and 55 were collected and returned to Amec's laboratory for analysis. <br />SLF Sample Number 103 -S through 107 -S were collected and returned to Amec's laboratory for analysis. <br />Clay samples from the WHEX area were returned to the Amec laboratory for analysis (possible clay source for soil liner <br />fill). <br />A small sample of Rip Rap material was obtained for testing purposes at the Grizzly screening plant located at the <br />Midway area above ADR haul road station 45 +00. The material was found to be within specification limits (02271.0). <br />Page 3 of 7 MLE2 WE l 5Febl4.doe <br />
