Description The “good neighbor” or “interstate transport” provisions of the federal Clean Air Act protect downwind states from harmful pollution that originates in upwind states. This State Implementation Plan (SIP) revision contains Washington’s analysis of the interstate transport of fine particulates (PM2.5). Our analysis suggests that Washington’s sources do not significantly contribute to PM2.5 air pollution in other states, affecting nonattainment or impeding maintenance areas. No new rules are proposed.
