noncancer Risk Action Levels for existing sources are identified in OAR
, Table 1.
toxic air contaminants for which an adjusted noncancer Risk Action Level will
apply are identified in OAR 340-247-8010
, Table 2, and OAR 340-245-8010
2 in the column named "Noncancer TBACT RAL."
An adjusted Risk Action Level will be
applied to existing sources that emit one or more toxic air contaminants
identified in OAR 340-247-8010
, Table 2, or OAR 340-245-8010
, Table 2 with a
noncancer TBACT RAL of a Hazard Index of 3. For sources that emit a mixture of
toxic air contaminants with noncancer TBACT Risk Action Levels of both a Hazard
Index of 3 and a Hazard Index of 5, the Risk Determination Ratio calculation
expresses the degree to which the applicable Risk Action Level may be adjusted
for each source.
