Mr. Timothy VanDomelen - 3 - 9 May 2008 <br /> J.R. Simplot, Lathrop <br /> Comment Source Resolution <br /> Number <br /> p. 2 pond lysimeters would be provided to the Regional Water Board <br /> in the second quarter 2008 monitoring report, <br /> due 1 August 2008. <br /> 12 Addendum The excavated soils from the process water release area were <br /> p. 4 and not disposed off-site, but put back into the plant process for the <br /> annual manufacture of fertilizer pellets. Soil was excavated and <br /> meeting sampled based on the presence of moisture and white sulfate <br /> precipitate. Initial samples were collected from the bottom of the <br /> excavation. Additional samples were collected one year after the <br /> release because John Yanak felt more sampling was needed. <br /> The excavation remains open until the proposed sampling is <br /> complete. <br /> 13 Addendum Additionally, sample EB-BF will be analyzed by D.I. WET <br /> p. 4 analysis and reported in the Progress Report due <br /> 21 October 2008. <br /> 14 Addendum See comment #2 above. <br /> p. 4 <br /> 15 Addendum Figure 2 shows that groundwater and soil samples will be <br /> p. 4 and collected from the same locations. EB-AK will be a discrete- <br /> Fi ure 2 depth sampling location in the berm surrounding the tank. <br /> 16 Addendum We discussed using a site-wide soil background sampling <br /> p.4 and location more representative of conditions outside the active <br /> Annual plant than EB-AY. Regional Water Board staff request a <br /> Meeting proposed alternate location for characterization of background <br /> soils. Please provide this information in a letter by <br /> 27 Ma 2008. <br /> 17 Addendum Step-out protocol is not technically feasible in the UN-32 release <br /> p. 4 and area because of containment berms and limited downgradient <br /> Annual area unaffected by former plant activities. Regional Water <br /> Meeting Board staff agreed to the proposed sampling as shown in Figure <br /> 3; however, more delineation may be required. <br /> 18 Addendum Additional sample from EB-AI will be analyzed by D. I. WET <br /> p. 4. analysis and reported in the Progress Report due <br /> 21 October 2008. <br /> 19 Addendum Groundwater from well LP-8 will be collected the week of <br /> p. 5 7 July 2008 and reported in the second quarter monitoring <br /> report due 1 August 2008. <br /> 20 Addendum Figure 3 shows location of the release area and proposed <br /> pp. 3 and 4, sample locations. Rationale for these locations was discussed <br /> and Figure during meeting. <br /> 3 <br /> 21 Addendum Additional sample from boring EB-AN will be analyzed by D.I. <br /> p. 4 and WET analysis and reported in the Progress Report due <br /> Appendix B 21 October 2008. <br /> Regional Water Board staff request full documentation in that <br />
