[EH] ; Vicki McCartney [EH] <br /> Subject: J&EModel questions• - - <br /> Hi Vicki, <br /> Iconfirmed with Paul that we are not using soil to evaluate soil gas, regardless of the } <br /> 2004 USEPA guidance. The 2010 State guidance <br /> (attached.) supercedes all prior State documents (page 11) and does not recommend using Y <br /> soil for soil gas evaluations. In fact, during a presentation to Regional Board staff in ` <br /> 2009, Dr. Ettinger stated that soil is not to be used for soil gas in the model during a �! <br /> question and answer period at my office. Please feel free to use .this guidance for your <br /> letter. Thanks. <br /> Jim Barton <br /> James L.L.
