NOTICE OF PUBLIC HEARINGState Implementation Plan Revision:
Interstate Transport
of Ozone and Fine Particulate Matter
The department of ecology (ecology) developed this
revision to the Washington state implementation plan (SIP) to
meet requirements of the Clean Air Act regarding interstate
transport of ozone (O3) and fine particulate matter (PM2.5). On
July 18, 1997, EPA promulgated revised National Ambient Air
Quality Standards (standards) for O3 and new standards for
PM2.5. When EPA adopts a new or revised air quality standard,
the Clean Air Act requires states to prepare a SIP, which is a
statewide plan for meeting federal standards. This SIP must
prohibit air pollutants in amounts that will contribute
significantly to nonattainment of standards, or interfere with
maintenance of the standards, in another state. It must also
prohibit air pollutants in amounts that will interfere with
measures in another state's SIP to prevent significant
deterioration of air quality or protect visibility. Ecology will hold a public hearing to receive comments on
this revision to the Washington SIP. The hearing is the first
of two separate ecology hearings, scheduled as follows:
Thursday, January 4, 2007, at 2:00 p.m., at the Department of
Ecology, 300 Desmond Drive, Auditorium Room 36, Lacey, WA.
Written comments must be postmarked no later than January
5, 2007, and should be sent to Doug Schneider, Department of
Ecology, P.O. Box 47600, Olympia, WA 98504-7600.
For more information about the updates or the SIP process
prior to the hearing, please contact Doug Schneider, (360)
407-6874.
