OAR 340-244-0210
Emission Standards: Emissions Limitation for Existing Sources
(1)
Federal MACT. Existing major and area sources must comply with the applicable emissions standards for existing sources promulgated by the EPA pursuant to section 112(d), section 112(n), or section 129 of the FCAA and adopted by rule within this Division.(2)
State MACT. If the EPA fails to meet its schedule for promulgating a MACT standard for a source category or subcategory, DEQ must approve HAP emissions limitations for existing major sources within that category or subcategory according to 40 CFR Part 63, Subpart B.(a)
The owner or operator of each existing major source within that category will file permit applications in accordance with OAR 340-218-0040 (Permit Applications) and 40 CFR Part 63, Subpart B.(b)
If, after a permit has been issued, the EPA promulgates a MACT standard applicable to a source that is more stringent than the one established pursuant to this section, DEQ must revise the permit upon the next renewal to reflect the standard promulgated by the EPA. The source will be given a reasonable time to comply, but no longer than 8 years after the standard is promulgated;(c)
DEQ will not establish a case-by-case State MACT:(A)
For existing solid waste incineration units where an emissions standard will be established for these units by the EPA pursuant to section 111 of the FCAA. These sources are subject to applicable emissions standards under OAR chapter 340, division 230; or(B)
For existing major HAP sources where an emissions standard or alternative control strategy will be established by the EPA pursuant to section 112(n) of the FCAA.(3)
Compliance schedule:(a)
The owner or operator of the source must comply with the emission limitation:(A)
Within the time frame established in the applicable Federal MACT standard, but in no case later than three years from the date of federal promulgation of the applicable MACT requirements; or(B)
Within the time frame established by DEQ where a state-determined MACT has been established or a case-by-case determination has been made.(b)
Notwithstanding the requirements of this section, no existing source that has installed Best Available Control Technology or has been required to meet Lowest Achievable Emission Rate before the promulgation of a federal MACT applicable to that emissions unit is required to comply with such MACT standard until 5 years after the date on which such installation or reduction has been achieved, as determined by DEQ.
