r <br /> Michael Oliphant -2 - 18 December 2013 <br /> Chevron <br /> Depending on the field results, additional borings and sampling may be proposed. Soil samples will <br /> also be collected and submitted for soil properties determination in support of evaluating the soil <br /> vapor pathways. <br /> If no further work is needed, the June 2005 HHRA will be revised and the additional data will be <br /> incorporated as an appendix. The revised HHRA will be submitted by 30 March 2014. <br /> Following review of the data collected the borings would be properly destroyed in accordance with <br /> San Joaquin County guidelines. Staff concurs with the proposed Workplan. <br /> If you have any questions please contact Dean Hubbard at (559) 445-5179 or by email at <br /> dean hubbard(d)waterboards.ca.gov. <br /> DANE S.
