notice of joint public hearing

Including Spokane County Air Pollution Control Authority Revised Regulations in the Washington State Implementation Plan

The Washington State Department of Ecology will be conducting a joint public hearing with the Spokane County Air Pollution Control Authority (SCAPCA) on January 7, 1999. The hearing will take place at 8:30 a.m. in the hearing room (lower level) of the Spokane County Public Works Building, 1026 West Broadway, Spokane, WA. Ecology is conducting the public hearing to receive comments on including amended SCAPCA regulations in the state implementation plan (SIP), a state-wide plan for meeting federal health-based standards for certain air pollutants.

The amendments are being made to satisfy the United States Environmental Protection Agency (EPA) requirements for revoking the federal air quality standard for particulate matter (PM₁₀). EPA adopted a new particulate matter standard in 1997, which will apply once the former standard is revoked. The amendments are to SCAPCA Regulation I, Article VI, Sections 6.14A (Applicability), 6.14B (Definitions), and 6.15B (Definitions). They are regarding paved and unpaved roads in the PM₁₀ nonattainment area.

For ecology's purposes, comments must be limited to including the amendments in the SIP. Written comments must be postmarked no later than January 7, 1999, and should be sent to Maxine Willis, Department of Ecology, P.O. Box 47600, Olympia, WA 98504-7600.

For more information on the content of the draft regulations prior to the hearing, please contact Eric Skelton at SCAPCA, (509) 477-4727 ext. 121.
