Or. Admin. Code § 340-223-0100 - Screening Methodology for Sources for Round II of Regional Haze

(1) The following sources are subject to the requirements of round II of regional haze, contained in OAR 340-223-0110 to OAR 340-223-0130:

(a) Stationary sources with a Title V operating permit; and

(b) That have a Q/d, as determined as provided in subsection (2), of greater than or equal to 5.00.

(2) To determine Q/d, DEQ shall calculate:

(a) A "Q" factor by adding the plant site emission limits for round II regional haze pollutants as stated in the permit for that source as of December 31, 2017;

(b) A "d" factor by determining the source's physical distance to the closest Class 1 area in Oregon or an adjacent state in kilometers, measured in a straight line from the source to the nearest boundary of a Class I area; and

(c) The ratio of Q divided by d for that source.

[NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.]
