A comprehensive water monitoring program of <br /> the permanent rock fill area will include the following: <br /> -observation wells below and within the permanent rock fill <br /> have, or will be drilled, to monitor the quantity and quality of <br /> the groundwater associated with that structure; <br /> -a 6 inch test hole has been drilled approximately 35 feet <br /> deep to the surface of the undisturbed material in the temporary <br /> fill area to monitor groundwater in that area. Six two-inch test <br /> holes will be constructed into the permanent fill, three into the <br /> river bed alluvium, and three stopping at the surface of the <br /> undisturbed material. Should poor water pressure develop in the <br /> fill, the Company will take remedial steps to rectify the problem. <br /> Water monitoring schedules for the tunnel <br /> portal area will be as follows: <br /> -all observation wells will be checked monthly for static <br /> water levels and quarterly water quality samples will be taken; <br /> -all surface sample points will be sampled quarterly except <br /> during spring melt runoff where flow and Total Suspended Solids <br /> (TSS) will be measured monthly; <br /> -all water quality samples will be analyzed for the following <br /> parameters: TSS, TDS, pH, Iron (Fe) , Manganese (Mn) , and Conductivity. <br /> (8) Mitigation of environmental impacts - west <br /> portal yard area. <br /> Mitigation and reclamation plans will be <br /> developed for this 3. 7 acre when the exact site is selected and <br /> the detailed face up and yard area plans are finalized. <br /> 44 <br />
