Excavation: 7:00 am to 5:30 pm. Up to (2) CAT D6 and (1) CAT D8 dozers with ripper attachments assisted up to (4) CAT 627 and (2) CAT 637 scrapers load material from the excavation along northwest and east sides of the cell. The soil was hauled and stockpiled at North West Stockpile for use as daily cover for active landfill operations, to the South Stockpile 2 for use as Operations layer soil, and to Earthfill construction along south side of the Cell. The soil was hauled on an approximate 5 -min cycle. (1) CAT 14H motorgrader was observed fine grading the north slopes (upper slopes) at the cell. North West Stockpile: 7:00 am to 5:30 pm. (1) CAT 14H motorgrader was observed spreading and grading the soil in the stockpile fill area and maintaining haul roads. (1) CAT 621 water pull was used to maintain fill areas and haul roads. South Stockpile 1 (Foundation): No activity was observed. South Stockpile 2 (Operations): 7:00 am to 5:30 pm.
