Sathees Contractor: R J Gordon Construction, Inc. Weather: Clear Wind: 0-10 mph. Temperature: ApErox. range 60-90 F Other: The contractor worked from 7:00 am to 5:30 pm. 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 north and east sides of the cell, and excavation of existing ramp at northwest corner of the cell. The soil was hauled and stockpiled at North West Stockpile for use as daily cover for current landfill operations, South Stockpile 1 for use as Foundation layer soil, at 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 and (1) CAT D6 dozer (with slope board attachment) part time trimmed the upper slopes along north and east sides of the cell. (1) CAT 621 water pull was used to maintain excavation areas and slopes. North West Stockpile: 2:00 pm to 5:30 pm. The scrapers hauled unsuitable soil from the existing ramp at northwest corner of the cell to North West Stockpile. (1) CAT 14H motorgrader was observed part time spreading and grading the soil in the Stockpile fill areas and maintaining haul roads. (1) CAT 621 water pull was used to maintain haul roads. South Stockpile 1 (Foundation): 2:00 pm to 5:30 pm. The scrapers hauled few loads of fine-grained materials from slopes along north side of the cell to the South Stockpile 1 for use as Foundation layer soil. (1) CAT 14H motorgrader was observed part time spreading and grading the soil in the Stockpile fill areas, and maintaining haul roads. (1) CAT 621 water pull was used to maintain stockpile fill areas and haul roads. South Stockpile 2 (Operations): 7:00 am to 5:30 pm.
