WAC 173-400-081   Startup and shutdown.  (1) In promulgating technology-based emission standards and making control technology determinations (e.g., BACT, RACT, LAER, BART) the permitting authorities will consider any physical constraints on the ability of a source to comply with the applicable standard during startup or shutdown.

     (2) Where the permitting authority determines that the source or source category, when operated and maintained in accordance with good air pollution control practice, is not capable of achieving continuous compliance with an emission standard during startup or shutdown, the permitting authority must include in the standard appropriate emission limitations, operating parameters, or other criteria to regulate the performance of the source during startup or shutdown conditions.

     (3) In modeling the emissions of a source for purposes of demonstrating attainment or maintenance of national ambient air quality standards, the permitting authorities shall take into account any incremental increase in allowable emissions under startup or shutdown conditions authorized by an emission limitation or other operating parameter adopted under this rule.

     (4) Any emission limitation or other parameter adopted under this rule which increases allowable emissions during startup or shutdown conditions over levels authorized in Washington's state implementation plan shall not take effect until approved by EPA as a SIP amendment.
