OAR 340-232-0040
General Non-Categorical Requirements
(1)
All existing sources operating prior to November 15, 1990, located inside the areas cited in OAR 340-232-0020 (Applicability)(1)(a) or (1)(c), containing emissions units or devices for which no categorical RACT requirements exist and which have potential emissions before add-on controls of over 100 tons per year of VOC from aggregated, non-regulated emission units, must have RACT requirements developed on a case-by-case basis by DEQ. Sources that have complied with NSR requirements per OAR 340 division 224 and are subject to Best Available Control Technology (BACT) or Lowest Achievable Emission Rate (LAER) requirements are presumed to have met RACT requirements. A source may request RACT not be applied by demonstrating to DEQ that its potential emissions before add-on controls are less than 100 tons per year. Once a source becomes subject to RACT requirements under this section, it will continue to be subject to RACT, unless VOC emissions fall less than 100 tons per year and the source requests that RACT be removed, by demonstrating to DEQ that their potential VOC emissions before add-on controls are below 100 tons per year.(2)
Within 3 months of written notification by DEQ of the applicability of this rule, or, for good cause shown, up to an additional three months as approved by DEQ, the source must submit to DEQ a complete analysis of RACT for each category of emissions unit at the source, taking into account technical and economic feasibility of available control technology, and the emission reductions each technology would provide. This analysis does not need to include any emissions units subject to a specific categorical RACT requirement under this division. These RACT requirements approved by DEQ will be incorporated in the source’s Air Contaminant Discharge Permit, and will be effective upon approval by EPA as a source specific SIP revision. The source must comply with the applicable RACT requirements beginning one year from the date of notification by DEQ of EPA approval.(3)
Failure by a source to submit a RACT analysis required by section (2) does not excuse the source from the obligation to comply with a RACT determination established by DEQ.
