Mr. Marshall Cloud <br /> November 19, 2003 <br /> Page 2 <br /> 3.) Page 2-7, section 2.4.2; This section needs to include DTSC's new regulation, <br /> section 67391.1 of the Title 22 California Code of Regulations requiring land use <br /> covenants which became final in April 2003. <br /> 4.) Page 2-7, section 2.3.8; the paragraph discusses how an addendum to the IMP <br /> must be prepared to place constraints ensuring that a specific type of land use, <br /> such as residential development, does not occur at DDJC-Tracy in the future. <br /> This addendum will be stored with the IMP and will include a map showing the <br /> location of the LUC areas at which specific development is prohibited. Since the <br /> ROD Amendment is a decision type document, it would be beneficial if the new <br /> IMP Addendum would be incorporated into the ROD Amendment as an <br /> Appendix. Then, if any LUC information needs to be revisited it would be readily <br /> available for any of the regulatory personnel without having to travel to the <br /> Facility Engineer's office or request a separate copy. Please insert the IMP <br /> Addendum into the ROD Amendment as an Appendix. <br /> 5.) Page 4-4, section 4.3.4; Please list the performance measures, specifically <br /> which types of activities are prohibited in this area to protect human health and <br /> the environment. For example, if construction activities producing dust are <br /> prohibited in the area to protect a construction worker then state this in the <br /> report. <br /> 6.) In July 2003, Treatment Plant #1 (TP#1) was shutdown to install a series of <br /> Granular Activated Carbon (GAC) vessels to help remediate the dieldrin and <br /> various pesticides residing in the groundwater at DDJC-Tracy. Although the <br /> report mentions the need to remediate the pesticides in the aquifer, it does not <br /> discuss the newly installed GAC vessels or elimination of the air-stripper at <br /> TP#1. Since the ROD Amendment encompasses OU-1 issues then it should <br /> account for the most recent additions to the groundwater treatment system. <br /> Please update the appropriate text and figures to account for the new changes in <br /> the treatment plant design. <br /> 7.) Pages 3-3/3-9, figures 3-1/3-2; on both figures there appears to be an extraction <br /> well (EW) represented by a green dot between CD-1 and IG-1. Please identify <br /> the EW in both figures. If it is not an EW, but rather a junction point showing <br /> where the line splits in two directions, then show this with another symbol that <br /> has not been defined in the legend. <br />
