JUN-25-2007 10:23 FUGRO WEST, INC. 1 510 269 0545 P.03iO4 <br /> FOLSOM SOUTH CANAL CONNECTION PIPELINE WORK PLAN <br /> PROJECT BACKGROUND <br /> The Folsom South Canal Connection(FSCC) Project is part of the larger Freeport <br /> Regional Water Project being implemented jointly by the Sacramento County Water <br /> Agency(SCWA)and the East Bay Municipal Utility District (EBIMUD). The FSCC <br /> project involves the design and construction of a new, raw water conveyance system that <br /> interconnects the existing United States Bureau of Reclamation, Folsom South Canal and <br /> the EBMUD Mokelumne Aqueduct. The FSCC project includes an intake structure and a <br /> 100-million gallons per day (mgd)pumping plant to be located at the end of the existing <br /> Folsom South Canal, 15 miles of 72 inch-diameter pipeline to convey water to an 8- <br /> million-gallon equalization tank and a 100 mgd pumping plant near Camanche Reservoir <br /> and 3 miles of 72-inch-diameter pipeline to convey water to the District's Mokelumne <br /> Aqueduct. <br /> SUBSURFACE EXPLORATION PROGRAM <br /> A conventional boring (i.e., 8-inch-diameter or less) will be drilled at the proposed <br /> location shown on Figure 1. The boring will be drilled to a maximum depth of 25 feet. <br /> The conventional boring will utilize hollow-stem-auger drilling techniques provided by <br /> PC Exploration, previously Major Drilling USA Inc. An engineer or geologist from <br /> Fug-ro will log and visually classify the soil materials encountered during the drilling <br /> operation and record groundwater levels. Ingeneral, samples will be obtained with a 2- <br /> inch outer- diameter SPT sampler and a 3-inch-outer-diameter Modified California <br /> sampler, as appropriate. Samples will be obtained approximately every 5 vertical feet of <br /> boring drilled. However, more closely spaced sampling will occur within the zone from <br /> about 5 feet above to about 5 feet below the proposed pipe zone. <br />
