(AGE) on your behalf and believes that conditions may <br /> warrant site closure consideration. The EHD requests that you submit a closure summary report. This <br /> report should include required data listed in Table 1 from Appendix A of the Tri-Regional Guidelines. <br /> While all items in Appendix A should be addressed, the EHD is particularly interested in the following <br /> to facilitate closure consideration: <br /> • Cross sections showing correlated soil lithologies, contaminant concentrations, lateral and <br /> vertical extents of impacted soil and groundwater, and contaminant migration pathways. <br /> • Tables of current and historical analytical soil and groundwater data. <br /> • Calculations showing current estimates of the residual dissolved and adsorbed contaminant <br /> masses of total petroleum hydrocarbons quantified as diesel, total petroleum hydrocarbons <br /> quantified as motor oil, total petroleum hydrocarbons quantified as gasoline, methyl tertiary- <br /> butyl ether, and 1,2-dichloroethane. <br /> • A modeled estimate of the future impact to groundwater from adsorbed contaminants. <br /> • An estimate of the projected maximum plume extent resulting from the modeled additional <br /> impact of groundwater, and <br /> • An estimate of when site conditions will meet water quality objectives (WQOs). <br /> Please contact Vicki McCartney at(209) 468-9852 or by email at vmccartney@sjcehd.com if you have <br /> any questions. <br /> Sincerely, <br /> Victoria L.
