Or. Admin. R. 340-212-0130 - Stack Heights and Dispersion Techniques
(1) 40 CFR parts 51.100(ff) through
51.100(kk), and 51.118, 51.160 through 51.166, concerning stack heights and
dispersion techniques, are adopted and incorporated herein. The federal rule
generally prohibits the use of excessive stack height and certain dispersion
techniques when calculating compliance with ambient air quality standards. The
rule forbids neither the construction and actual use of excessively tall
stacks, nor the use of dispersion techniques. It only forbids their use in
noted calculations. The rule generally applies as follows. Stacks 65 meters
high or greater that were constructed after December 31, 1970, and major
modifications made after December 31, 1970 to existing plants with stacks 65
meters high or greater which were constructed before that date are subject to
this rule. Certain stacks at federally owned, coal-fired steam electric
generating units constructed under a contract awarded before February 8, 1974
are exempt. Any dispersion technique implemented after December 31, 1970 at any
plant is subject to this rule. However, if the plant's total allowable
emissions of sulfur dioxide are less than 5,000 tons per year, then certain
dispersion techniques to increase final exhaust gas plume rise may be used when
calculating compliance with ambient air quality standards for sulfur dioxide.
