Or. Admin. R. 340-226-0140 - Highest and Best Practicable Treatment and Control: Additional Control Requirements for Stationary Sources of Air Contaminants
In addition to other applicable requirements, DEQ may establish control requirements by permit if necessary as specified in sections (1) through (5):
(1) Requirements will be
established to prevent violation of an ambient air quality standard caused or
projected to be caused substantially by emissions from the source as determined
by modeling, monitoring, or a combination thereof. For existing sources, DEQ
will conduct monitoring to confirm a violation of an ambient air quality
standard.
(2) Requirements will be
established to prevent significant impairment of visibility in Class I areas
caused or projected to be caused substantially by a source as determined by
modeling, monitoring, or a combination thereof. For existing sources, DEQ will
conduct monitoring to confirm visibility impairment.
(3) A requirement applicable to a major
source will be established if it has been adopted by EPA but has not otherwise
been adopted by the EQC.
(4) An
additional control requirement will be established if requested by the owner or
operator of a source.
(5)
Requirements will be established if necessary to protect public health or
welfare for the following air contaminants and sources not otherwise regulated
under OAR 340 divisions 200 through 268:
(a)
Chemical weapons; and
(b)
Combustion and degradation by-products of chemical weapons.
NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040
