Public Hearing

Air Quality Program

Including Vancouver Carbon Monoxide Maintenance Plan

in the State Implementation Plan (SIP)

The department of ecology (ecology) is holding a public hearing on including a second ten-year carbon monoxide (CO) maintenance plan for Vancouver, Washington in the state implementation plan (SIP). The SIP is a statewide plan for meeting federal air quality standards.

Background information: The federal Environmental Protection Agency (EPA) redesignated the Vancouver area to attainment of the CO standard in 1996 after finding that the area met Clean Air Act requirements for redesignation. These requirements include:

Monitoring data showing the area meets the standard, and
An EPA-approved plan for maintaining the standard for an initial ten-year period.
After a redesignated area has met the standard for ten years, the Clean Air Act requires a maintenance plan for the second ten years of the maintenance period as part of the SIP. The Southwest Clean Air Agency developed a maintenance plan for the Vancouver area. The maintenance plan assures that the area will continue to meet the carbon monoxide standard for a second ten-year period.

Since Vancouver's carbon monoxide levels are so low, EPA has determined the area is not likely to exceed the standard. Therefore, EPA is requiring only a limited maintenance plan to meet the Clean Air Act requirement. Since the area is unlikely to exceed the standard, the plan continues the existing control strategy, does not need to demonstrate maintenance of the standard, and exempts the area from regional transportation conformity determinations. Other conformity requirements, such as project conformity and consultation, remain.

The hearing: Ecology will hold a hearing following the Southwest Clean Air Agency's March board meeting. The board will adjourn after completing its business meeting and ecology will provide a short break before beginning the SIP hearing.

The date and location of the hearing are: Thursday, March 1, 2007, at 3:00 p.m., at the Southwest Clean Air Agency, 11815 N.E. 99th Street, Suite 1294, Vancouver, WA 98682.

The purpose of the hearing is to receive public comment on including the Southwest Clean Air Agency's maintenance plan in the SIP.
