Spokane Carbon Monoxide Serious Nonattainment Area:

Proposed State Implementation Plan Revision



The Washington State Department Ecology (ecology) is conducting a hearing to receive public comment on a proposed revision to the state implementation plan (SIP) for the Spokane carbon monoxide (CO) nonattainment area. The SIP is a statewide plan for meeting federal air quality standards.

The United States Environmental Protection Agency (EPA) has set an air quality standard for CO and designated Spokane as a nonattainment area due to exceedances of that standard. Ecology is responsible for developing a plan to meet the CO standard. This plan then needs to be submitted as a revision to the SIP.

Ecology submitted a plan to meet the standard on September 14, 2001. The plan included a transportation control measure (TCM) necessary for demonstrating attainment of the standard. The Federal Highways Administration identified adverse safety and operational impacts related to the TCM that could not be mitigated. For EPA to approve the plan for Spokane, an alternative TCM that would demonstrate attainment of the CO standard was required. After reviewing multiple TCMs, the Spokane Regional Transportation Council (SRTC) determined that adding a left turn channel on eastbound Third Avenue at Washington demonstrates attainment of the CO standard.

The SIP revision withdraws and replaces several sections of the Spokane CO attainment plan (September 14, 2001, Publication No. 01-02-009). The sections of the plan that are being revised are:

Chapter 3, Section 3.3, Periodic Emission Inventories

Chapter 5, Sections 5.5, Attainment Demonstration and, 5.6, Transportation Control Measure Used to Demonstrate Attainment

Chapter 7, Section 7.1, Plan Commitments

Appendix E, Attainment Demonstration (select sections identified in Appendix E of this SIP revision)

Copies of the plan are available for review at the Spokane County Air Pollution Control Authority, 1101 West College, Suite 403, Spokane, WA 99201; at the Spokane Public Library, 906 West Main, Spokane, WA 99201; at the Spokane Regional Transportation Council, 211 West First Avenue, Suite 310, Spokane, WA 99201; and at the Department of Ecology, Eastern Regional Office, 4601 North Monroe Street, Spokane, WA 99205-1295.

Hearing Schedule: On Tuesday, October 26, 2004, at 4:45 p.m., at the Washington Department of Ecology, Eastern Regional Office, 2nd Floor Conference Room, 4601 North Monroe Street, Spokane, WA 99205-1295.
