OAR 340-247-0010: Purpose and Overview

Purpose and Overview. Division 247 lists air contaminants that are a priority for investigation in Oregon (Table 1), lists health risk-based standards for toxic air contaminants in Oregon (Table 2) and establishes the process for setting and updating these values. These scientific standards, also called toxicity reference values (TRVs), are used to help analyze public health risk from toxic air contaminants. These standards may be used by programs including, but not limited to, Cleaner Air Oregon (OAR-340-245) and the Oregon State Toxic Air Contaminants Program (OAR-340-246). Subject to the requirements in this division and OAR 340-200-0010(3), Lane Regional Air Protection Agency is designated by the EQC to implement the rules in this division within its area of jurisdiction.
