i <br /> Mr. Kenneth Earnest <br /> May 20, 1994 <br /> Page 3 <br /> 1994, indicated an average benzene fraction of 0.7 percent. The resulting estimated amount of <br /> benzene extracted during this period is 7 pounds. As of Februga 28, 1993, the cumulative <br /> extraction amounts since start-up of the system are 7,457 pounds of hydrocarbons and 210 <br /> pounds of benzene. <br /> February 28 to March 25, 1994 <br /> (T:h:e �sy��sterm� �r�a�nco�ntipuousl .�The estimated amount of hydrocarbons extracted during this <br /> periodpeod is 1,423 pounds (baseon field readings). The laboratory results fo two influent air <br /> samples collected on March 11 and 25, 1994, indicated that both were elow the detection limi <br /> for benzene. The resulting estimated amount of benzene extracted is 0.0 pound. Therefore, as <br /> of March 25, 1994, the cumulative totals of hydrocarbons and benzene extracted since start-up <br /> of the vapor system are 8,880 and 210 pounds, respectively. <br /> Enclosure A contains copies of laboratory analytical reports.
