lit <br /> Station No, 502, 35 N. Cherokee Lane, Lodi, - Interim Remediation Plan <br /> within the BMQMD,s 1 to 10 acceptable excess cancer risk range for T- <br /> BACT operations. The actual duration of the program is expected to be <br /> only a year or less. <br /> This risk assessment did not account for' the fact that the public health <br /> risk could actually be higher if theca t—C ______. <br /> �..

To convert the hourly concentration to risk, <br /> simply multiply the PTPLU czmputed hourly value by 0,1 to annualize the <br /> concegtration and then multiply again by the benzene Unit Risk Value (2.9 <br /> x 10- ) to obtain the excess risk in cases per million population for a <br /> full 70 year lifetime exposure period. The actual duration of -the <br /> program is a small fraction of the 70 year exposure period used for this <br /> �.. conservative risk assessment. <br /> PLAN DISTRIBUTION <br /> �. <br /> We recommend that copies of this plan be distributed as follows: <br /> 4i Ms. Margaret Lagorio, Senior REHS (204) 468-3449 <br /> Environmental Health Services <br /> San Joaquin County Public Health Services <br /> € P.O.
