OAR 340-226-0110: Highest and Best Practicable Treatment and Control: Pollution Prevention

The owner or operator of a source is encouraged to take into account the overall impact of the control methods selected, considering risks to all environmental media and risks from all affected products and processes. The owner or operator of a source is encouraged, but not required, to use the following hierarchy in controlling air contaminant emissions: (1) Modify the process, raw materials or product to reduce the toxicity and quantity of air contaminants generated; (2) Capture and reuse air contaminants; (3) Treat to reduce the toxicity and quantity of air contaminants released; or (4) Otherwise control emissions. NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.
