Because of tale location of the probe, <br /> and the lack of human habitation in the arca, we do not believe that human health was <br /> threatened, All other probes were found in compliance at that time. <br /> The remediation plan for this situation is to increase the collection rate at.nearby LFG collection <br /> wells EW-B 1, 41 6,7,and 8,and f ona the LFG control system as a whole. This plan was <br /> implemented on March 27,2002. Today(March 29, 2002) the methane content has decreased <br /> to 7.0%. <br /> We expect that the methane content at this probe will continue to decrease, and will be below the <br /> compliance limit of 5% shortly. We will monitor this;probe and adjust the nearby LFG wells at <br /> least weekly to ensure that this is accomplished, and will inform you by e-mail ai"significant <br /> developments. <br /> If you have any questions,please contact tree at 468-3066, <br /> Sincerely, <br /> W.
