(1) RACT as defined in RCW
70A.15.1030 is required for existing sources except as otherwise provided in RCW
70A.15.3000(9).
(2) RACT for each source category containing three or more sources shall be determined by rule except as provided in subsection (3) of this section.
(3) Source-specific RACT determinations may be performed under any of the following circumstances:
(b) When required by the federal clean air act;
(c) For sources in source categories containing fewer than three sources;
(d) When an air quality problem, for which the source is a contributor, justifies a source-specific RACT determination prior to development of a categorical RACT rule; or
(e) When a source-specific RACT determination is needed to address either specific air quality problems for which the source is a significant contributor or source-specific economic concerns.
(4) By January 1, 1994, ecology shall develop a list of sources and source categories requiring RACT review and a schedule for conducting that review. Ecology shall review the list and schedule within six months of receiving the initial operating permit applications and at least once every five years thereafter. In developing the list to determine the schedule of RACT review, ecology shall consider emission reductions achievable through the use of new available technologies and the impacts of those incremental reductions on air quality, the remaining useful life of previously installed control equipment, the impact of the source or source category on air quality, the number of years since the last BACT, RACT, or LAER determination for that source and other relevant factors. Prior to finalizing the list and schedule, ecology shall consult with local air authorities, the regulated community, environmental groups, and other interested individuals and organizations. The department and local authorities shall revise RACT requirements, as needed, based on the review conducted under this subsection.
(5) In determining RACT, ecology and local authorities shall utilize the factors set forth in RCW
70A.15.1030 and shall consider RACT determinations and guidance made by the federal environmental protection agency, other states and local authorities for similar sources, and other relevant factors. In establishing or revising RACT requirements, ecology and local authorities shall address, where practicable, all air contaminants deemed to be of concern for that source or source category.
(6) Emission standards and other requirements contained in rules or regulatory orders in effect at the time of operating permit issuance or renewal shall be considered RACT for purposes of permit issuance or renewal. RACT determinations under subsections (2) and (3) of this section shall be incorporated into operating permits as provided in RCW
70A.15.2260 and rules implementing that section.
(7) The department and local air authorities are authorized to assess and collect a fee to cover the costs of developing, establishing, or reviewing categorical or case-by-case RACT requirements. The fee shall apply to determinations of RACT requirements as defined under this section and RCW
70A.15.3000(9). The amount of the fee may not exceed the direct and indirect costs of establishing the requirement for the particular source or the pro rata portion of the direct and indirect costs of establishing the requirement for the relevant source category. The department shall, after opportunity for public review and comment, adopt rules that establish a workload-driven process for determination and review of the fee covering the direct and indirect costs of its RACT determinations and a methodology for tracking revenues and expenditures. All such RACT determination fees collected by the delegated local air authorities from sources shall be deposited in the dedicated accounts of their respective treasuries. All such RACT fees collected by the department from sources shall be deposited in the air pollution control account.
