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, Cl<jLjO Joe bedvina % cc: FGJ VAB.0001154134 rI
