This is a delay of seven weeks. <br /> Secondly, Board staff has asked that we speciate soil gas VOCs with EPA Method TO-14. <br /> Although we are pleased to use the method requested, at least two more weeks will be needed to <br /> obtain laboratory results from Method TO-14, compared to Method 8260B,which was originally <br /> proposed. <br /> Thirdly, the Local Enforcement Agency has asked us to drill out the casing of existing well <br /> MW-2 rather than simply filling the casing with concrete slurry. This added an additional four <br /> working days (approximately one week)to the project. <br /> Based on this, we ask for an extension of ten weeks,to August 11, 2003, for the submittal of the <br /> Engineering Feasibility Report based on the results of this Evaluation Monitoring Program. <br /> If you have any questions,please call me at(209)468-3066. <br /> Sincerely, <br /> W.
