OAR 340-245-0320
Standards and Criteria for Noncancer Risk Action Levels for Existing Contamination Sources

(1) The noncancer Risk Action Levels for existing sources are identified in OAR 340-245-8010 (Table 1 - Risk Action Levels), Table 1.
(2) The toxic air contaminants for which an adjusted noncancer Risk Action Level will apply are identified in OAR 340-245-8030 (Table 3 - Toxicity Reference Values), Table 3, and OAR 340-245-8040 (Table 4 - Risk-Based Concentrations), Table 4, in the column named “Noncancer TBACT RAL.”
(3) An adjusted Risk Action Level will be applied to existing sources that emit one or more toxic air contaminants identified in OAR 340-245-8030 (Table 3 - Toxicity Reference Values), Table 3, or OAR 340-245-8040 (Table 4 - Risk-Based Concentrations), Table 4, 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.
