Multiplication of the unit risk factor by the fcnceline concentration provides a worst case estimate of risk from a particular facility. As state air toxic programs become prevalent, the unit risk factor will bo more of an issue. I am interested in others' experience or knowledge on what factor is being used to estimate risk from their facilities. If you could poll the members 1 would appreciate it. Sincerely, ,(0 Ledvina cc: FGJ CTL015878
