Work Plan for Refined Plume Defnition and Management of Floating Product-7500 W 11th St., Tracy, C.4. Page 85 <br /> 15.0 PROJECT SCHEDULE <br /> Schedules for the various elements of the proposed work have been presented, together with <br /> cost estimates in Sections 6.1, 7.9, 8.9, 9.4.1.8, 9.4.2.5, 9.4.3.8 and 10.2.1. If it is assumed <br /> that S3C's recommendation with respect to the technology to be used for removal of floating <br /> product is followed and the assumptions made regarding the length of time over which <br /> groundwater-quality monitoring must continue prove to be correct, the following time lines <br /> and milestones can be used for general planning purposes. <br /> Milestone Elapsed Time from <br /> Authorization to Proceed <br /> Complete Work Plan Completed <br /> Initiate Field Work for 30 Days <br /> Installation of New Wells <br /> and Floating Product <br /> Cut-off Trench <br /> Complete Well Construction 60 Days <br /> and Development <br /> �-.
