n Page 2 of 3 <br /> We hope this provides the appropriate clarification. Let's get this site closed. There appears little <br /> reason to have this one linger on. We can be ready tc abandon wells within days of approval by <br /> our Client. <br /> Let me know if you need anything else. <br /> Thanks, <br /> Robert E.

Please forward them to me if they are not in GeoTracker. Thanks. <br /> Jim <br /> James L.L.

Instead, they used die el soil data and conducted an ESL <br /> evaluation. Nuel commented that 5,300 mg/kg of TI1Hd is roughly one order of magnatude <br /> OVER gross contain levels for "middle distillates" . The site is capped with black top and <br /> concrete and is now, and will be/stay, an active fuel/ as station in the future. <br /> Margaret asked me to check with you if actual soil vapor samples must be collected when gross <br /> contam and exposure ESLs are exceeded like this. <br /> GW is non detect and roughly 15-18' bgs. They're a suspended C site and looking for NFA. <br /> you want to discuss it at the meeting or accept the ju tification and proceed to NFA? <br /> site ID # T0607760365 <br /> 1/27/2010 <br />
