PUBLIC NOTICE
PUGET SOUND CLEAN AIR AGENCY
Proposed Regulatory Order No. 12131

Joint Base Lewis-McChord
IMCOM
Fort Lewis, WA  98433

The Puget Sound Clean Air Agency (the Agency) is providing public notice for a proposed Regulatory Order for Joint Base Lewis-McChord (JBLM) to limit emissions of oxides of nitrogen (NO_x), carbon monoxide (CO), and volatile organic compounds (VOCs) to less than 95 tons per 12-month rolling period.

JBLM is currently operating under Regulatory Order 11247 which provides JBLM with federally enforceable emission limits establishing it as a minor source of air pollution. This proposed Order will cancel and supersede Regulatory Order 11247. Proposed revisions include limiting only pollutants with the potential to exceed major source levels, lowering the emission limits to be consistent with EPA guidance, and revising monitoring to reflect updated potential emission calculations. The proposed Order is a Regulatory Order reviewed under PSCAA Regulation I 3.03(f). This notice is published pursuant to WAC 173-400-091 and WAC 173-400-171(3)(k).

PRELIMINARY DETERMINATION

The Agency has completed a review of application No. 12131 and has made a preliminary determination that the proposal meets all the requirements of Regulations I, II and III and should be approved.
