The analysis of the vapor stream during the pilot test show that a <br /> uncontrolled system would produce approximately a pound of benzene <br /> a da Due to the high vapor pressure of benzene, benzene is one <br /> g of tKe compounds that is most susceptible to vapor extraction and <br /> thus would be diminished in its concentration in the vapor stream <br /> --- -as extraction goes on. With this in mind a emission controlled by <br /> the above iR analyzer, which Would control the amount of the vapor <br /> stream produced from the extraction wells, would keep the <br /> ®missions at or below the allowable emissions already allocated <br /> for this site. <br /> If you have any questions, please call (916) 663-4541. <br /> Sincerely yours,- <br /> George Converse Jack E.
