0 <br />u <br />KLEINFELDER <br />It appears that both food and drinking water in California may contain significant amounts of <br />asbestos. In light of these findings, the 30,000 fibers/liter standard does not seem reasonable. <br />Therefore, Kleinfelder proposes. that the 7 MFL (> 10 microns) standard be used as a water <br />quality goal for surface water runoff entering the channel. Of course, if upgradient asbestos <br />levels (> 10 microns) exceed the 7 MFL water quality goal, the background- level would be <br />used as the goal for surface water runoff entering the channel. <br />6.3.2.1 Phase I <br />Plate 6-I shows the Phase 1 drainage plan. Drainage from the capped and remediated areas is <br />directed through either small channels or swales to the main channel where the runoff will be <br />discharged. Periodic monitoring will occur at these discharge points to assess if the <br />concentration of asbestos fibers exceeds the proposed water quality goal of 7 NFL for fibers <br />greater than 10 microns in length. If the water quality goal is exceeded, Phase II will be <br />implemented. A statistical method for assessing exceedance will be negotiated with the <br />CVRWQCB. <br />6.3.2.2 Phase H <br />Phase II involves collecting storm water runoff from the landfills and soil remediation areas <br />and routing those flows through sedimentation basins to reduce the amount of asbestos in the <br />water discharged to the channel. Plate 6-2 shows the configuration of the drainage system. <br />The sizes shown for the sedimentation ponds are conceptual and are based on a number of <br />design assumptions. Appendix B contains a discussion of how the sedimentation ponds were <br />Sized. <br />CR14-92-12 Page 33 of 39 24-220109-FO9 <br />Copyright 1992 KLeinfetder, Inc. <br />Beer 4 <br />1.1-6.6 <br />Sherry 3 <br />2-2.6 <br />Port 1 <br />2.1 <br />Vermouth 2 <br />1.8-11.7 <br />Soft Drinks 4 <br />1.7-12.2 <br />KLEINFELDER <br />It appears that both food and drinking water in California may contain significant amounts of <br />asbestos.
