OAR 340-226-0100: Highest and Best Practicable Treatment and Control: Policy and Application

(1) As specified in OAR 340-226-0110 through 340-226-0140 and sections (2) and (3), DEQ will include appropriate conditions in permits to ensure that the highest and best practicable treatment and control of air contaminant emissions is in every case provided so as to maintain overall air quality at the highest possible levels, and to maintain contaminant concentrations, visibility reduction, odors, soiling and other deleterious factors at the lowest possible levels. The permit conditions must ensure that the degree of treatment and control provided must be such that degradation of existing air quality is minimized to the greatest extent possible. (2) The EQC encourages the owner or operator of a source to further reduce emissions from the source beyond applicable control requirements where feasible. (3) Nothing in OAR 340-226-0100 through 340-226-0140 revokes or modifies any existing permit term or condition unless or until DEQ revokes or modifies the term or condition by a permit revision. [NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.]
