action plan. This plan includes installing 3 more LFG extraction wells in LF -1 as previously <br />detailed in our August 30, 2018 response to the Board's June 6, 2018 notice of violation. <br />The County is advancing as fast as possible to purchase and install a new compliant LFG flare <br />station that will be able to extract and destroy additional LFG produced by the new LFG <br />extraction wells. These wells and the flare will be installed concurrently in accordance with the <br />schedule detailed in our August 30, 2018 response. <br />In addition, since the amount of condensate and concentrations of VOCs at the LZ -4 location is <br />decreasing, and since essentially no water has been extracted from the other suction lysimeters <br />under LF -2, a Work Plan for further evaluation is as follows: <br />• Continue monthly monitoring for the presence of extractable water at the LZ -4 location <br />• If sufficient water is extracted for VOC analysis, submit the water sample for testing by <br />EPA method 8260 in accordance with the site's waste discharge requirements (WDRs) <br />• If insufficient water is extracted for testing, continue monitoring for the presence of <br />extractable water on a quarterly basis for one year at the LZ -4 location <br />• If insufficient water is extracted for testing for a period of one year, continue monitoring <br />for the presence of extractable water on a semiannual basis at the LZ -4 location in <br />accordance with the WDRs <br />If you have any questions, please contact Juan Acevedo, Engineer III, at (209) 468-3066. <br />Sincerely, <br />TAJ M.
