DEQ Seeks Public Comment on Proposed Amendments to CAO Hazard Index Rules

The proposed Cleaner Air Oregon Hazard Index rules address provisions of Senate Bill 1541 that allow DEQ to establish more protective health standards for noncancer toxic air contaminants that are expected to cause developmental or other severe human health impacts. The proposed rules base the Risk Action Levels, or benchmarks, for existing sources emitting these chemicals on a noncancer Hazard Index value of 3, if the chemical is expected to cause developmental or other severe human health effects.
