e Mr. Carl Mount/DMG - F Street Additional Soil Abatement & Sampling PnRnGON <br />Project Number 1001018 <br />October 26, 2007 <br />Page 3 <br />groundwater sample collected from the abatement excavation in October 2007. TEPH <br />concentrations in groundwater are not regulated by a numeric standard in Colorado. <br />It is our opinion that additional monitoring, assessment or abatement is not warranted at the <br />site at this time. On behalf of Aggregate Industries, we request that DRMS grant site closure <br />for the 2001 diesel-fuel release. If you have any questions or require additional information, <br />please contact us. We look forward to your written response regarding our request for site <br />closure. <br />Sincerely, <br />PARAGON CONSULTING GROUP, INC. <br />Scott A.
