Attached please find: 1) a detailed response to <br /> your correspondence, 2) a summary of historical contaminant trends (Exhibit A), and 3) <br /> supporting figures (Figures B, C, and D). <br /> Based on the natural attenuation of the plume (as demonstrated in the attachments) and lack of <br /> groundwater sensitive receptors to the site, this site appears to be a good candidate for risk-based <br /> closure criteria. Mr. Dhoot requests that Stratus Environmental, Inc. (Stratus), be allowed to <br /> submit a work plan proposing a human health and environmental risk assessment., including the <br /> collection of soil gas data for use in modeling. Based on the results of the vapor sampling and <br /> risk assessment, Stratus proposes to develop Site Specific Toxicity Levels (SSTLs) which they <br /> can use to re-evaluate the need for active and/or localized remediation of the residual dissolved- <br /> phase MTBE plume. <br /> Further, based on the rationale provided in the attached documents (see detailed response and <br /> Exhibit A), we believe Wells MW-5, MW-6, MW-14B, and MVAC}-I should be dropped from the <br /> groundwater monitoring program. Mr. Dhoot hereby requests permission to discontinue <br /> sampling and to abandon these wells. <br /> Based on the current and historical contaminant trends at this Site demonstrated in the attached <br /> documents, we believe the tasks proposed herein are relevant and appropriate at this time and <br /> that they are consistent with the recommendations provided State Water Resources Control <br /> Board (SWRCB) entitled Preliminary 5-Year Review Summary Report, dated May 28, 2009. Mr. <br /> Dhoot is anxious to proceed with the tasks proposed above and perform the work necessary to <br /> receive closure as soon as possible. <br />
