Page 3 of 4 <br /> samples appear to provide data you can use in the models. Some times this <br /> 'old' soil data paints a bad picture in the models. So I'm seeing consultants <br /> opting for newer soil data. This usually means additional subsurface soil and <br /> vapor sampling. This is taking longer than two QMs usually span. My point? <br /> these two 'last' QMs may NOT be your last two. <br /> I agree getting the lab data now can only help. But/and if you detect any <br /> level of significance with the new constituents you'll be adding to the QMs, <br /> additional investigation/delineation may be required. This could set back <br /> your QM/NFAR schedule. And if these new constituents DO show up and <br /> you have to step out and down, you could incorporate soil vapor sampling into <br /> the additional work. just a thought. <br /> a recommendation: run your paper vapor intrusion eval now. See what <br /> happens. Other UST sites that have failed the Tier I VI phase are <br /> collecting soil and soil vapor data to provide 'current' data to model or <br /> empirical data to support ND, if that's the case. Experience has shown me <br /> that from onset of work plan compilation for VI soil vapor data to EHD <br /> getting the report of findings is taking 6 months to a year...something you <br /> may want to take into consideration before calling these last two QMs your <br /> "last". <br /> let me know your thoughts. <br /> From: John F.

Wright will <br /> strengthen the language in subsequent QM Reports to that effect. <br /> The following appear to be the only additional Laboratory work required for the next two <br /> quarterly monitoring events to round out the"LUFT Suite" for the Cox and Cox (aka Mr. <br /> Ed's Muffler) site here in Tracy. Please add the following to your scope of work and the <br /> next QM event. Hold after the last event this year until EHD provides instruction after <br /> reviewing the fourth quarter data. <br /> 8/23/2006 <br />
