Site work: 0700-1730
Mobilized four operators and one truck driver to the site. Equipment drivers took Weyerhauser road to site and unloaded heavy equipment on west side of last bridge before site. ERRS equipment operators walked equipment across the bridge. Received the Kobelco, 966 Cat Front End Loader, Service Truck and D6 Dozer on site.
ERRS Safety talk. Site orientation. Grubbed, widened and graded road to site. Repository location chosen. Strategy developed to address waste rock from Main Tailings pile. Grubbed, cleared and graded repository area. Used XRF to determine that material could be used as clean cover in New Furnace area. Used XRF on New Furnace area and identified where clean cover should be placed. Decided to cover New Furnace area with 1.5 feet of material from Main Tailings pile or repository area if mercury in cover material is below 115 mg/kg Hg. Decided to test each batch of cover material to be moved and to test the surface of caps after covering for confirmation. Locked gate with our locks at end of day. Entered XRF mercury data into Scribe and uploaded to Scribe.net.
On site this day: dozer (no cab), front end loader, excavator, water truck, 2 PU

6th Street bridge to London Road closed this morning for at least a year. Crew had to detour and find another way to the site. EQM held its daily safety meeting at 0700 hours. Analyzed Old Furnace Area for mercury using XRF. The Kobelco excavator started grading and laying back the east slope on the Dennis Creek area. The crew loaded the water truck at an approved location on Cottage Grove Lake. Two office trailers were mobilized to the site location, set up and tied down. An electrician was scheduled for power hook up tomorrow. A 45kw generator was received on site and will be used to power the two office trailers. Access roads to the Dennis Creek area, New Furnace area were graded and compacted by the D6 dozer and 966 front end loader. A 8’ x 20’ Storage Container was received on site. The rental water truck was filled at an approved location on Cottage Grove Lake. The water in the lake has dropped several feet since last visited in July 2007.

EQM held its daily safety meeting at 0700 hours. Analyzed East Main Tailings pile for mercury with the XRF. Set up one DataRam in the Main Tailings work area. Recommended changes to the site safety plan. Diesel fuel was delivered to the onsite service truck at 0930 hours. A 30ton haul truck was delivered to the site at 1000 hours. The 9060 Case excavator started excavation on west slope of Dennis Creek. The excavated material was placed and compacted by the 966 Cat loader and D6 Dozer on the top bench of the west slope. Eight loads were hauled to the New Furnace area and used as cap material. The Kobelco excavator continued excavation of the east slope on Dennis Creek. Nine loads were hauled to the New Furnace area and used as cap material. The D6 dozer the excavator in grading and shaping the slopes The water truck provided dust control on the haul roads and excavation areas as well as the material on the New Furnace area. The material hauled to the New Furnace area was compacted by track walking the D6 with three passes over the entire compacted area. The scheduled electrician arrived on site to hook up power to the two office trailers.

EQM held its daily safety meeting at 0700 hours. Continue excavation of material off east and west slopes of Dennis Creek. Hauled the material to a designated stockpile by the repository area. The area at the New Furnace location is 60% graded and capped. We now have the second truck driver on site and he will be driving the 30ton haul truck. The roads, excavation areas and stockpile locations are getting dusty and requires more water. Set the satellite dish on the roof of the EPA trailer. 506 gallons of diesel fuel was delivered to the site today. Estimate will use approx. 350 gallons of fuel per day until finished with the excavation on the slopes at Dennis Creek. Analyzed Furnace Creek for mercury with the XRF. Collected soil samples for Lumex analysis from same area. Set up DataRam in the Main Tailings work area.
Equipment on site: 2 excavators, 1 dozer, 1 loader, 1 haul truck, 1 water truck, 1 service truck, 2 - 10x40' trailers, 20' conex, 45 KW generator.
