The Workplan was <br /> prepared by Hydrotech Consultants, Inc. (Hydrotech) . The <br /> Workplan was intended to set forth the various RI/FS/draft RAP <br /> activities that will be undertaken at the Acme-Stockton <br /> Galvanizing Works (ASG) site (the Site) . <br /> In general, the Workplan is well done. There are, however some <br /> areas that are deficient. Comments on particular items are as <br /> follows: <br /> 1. The McKesson Environmental Services Investigation Report of <br /> 20 July 1983 indicates (Table 2) that soil samples were analyzed <br /> for pesticides and PCB's. What were the results of these <br /> analyses and why were they done? Is there a history of these <br /> materials on the property? Is there a history of the use or <br /> storage of organic chemicals on the site? We suggest that you do <br /> some screening for organics using an HNU or OVA during sampling <br /> of ground water and soils. <br /> The following comments are on the Workplan submitted by <br /> Hydrotech. <br /> 2 . Page 2 , section 1. 2 and Page 38, sections 5. 0 and 6. 0. <br /> Include an implementation schedule for activities necessary to <br /> complete the Feasibility Study through Final Remedial Action Plan <br /> (eg. Gantt Chart) . The Remedial Investigation Report, <br /> Feasibility Study Report, draft Remedial Action Plan, and <br /> Community Relations Plan can be added as chapters to the Remedial <br /> Investigation/Feasibility Study Workplan to constitute the <br /> Remedial Action Plan. <br />
