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. The soil was hauled and stockpiled 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. North West Stockpile: No activity was observed. South Stockpile 1 (Foundation): No activity was observed. South Stockpile 2 (Operations): 7:00 am to 5:30 pm. The scrapers hauled the generally sandy materials from upper slopes along north and east sides of the cell to the South Stockpile 2 for use as Operations layer soil.
