Air Quality Program
Including Revised Emission Check Rules in the
State Implementation Plan
What is the Emission Check Program? The emission check program tests vehicle emissions to identify the most polluting vehicles. It requires these vehicles to be repaired so that their emissions are reduced. The emission check program is a key to helping Washington state meet federal air quality standards. It is included in the SIP as a control for ozone and carbon monoxide air pollution in the Puget Sound and Vancouver areas, and for carbon monoxide in Spokane.
What Did Ecology Change in the Rule? The Washington state emission check program rule is in chapter 173-422 WAC, Motor vehicle inspection. Ecology revised nine sections of this rule in June 2002. The most important changes allow late model vehicles to be tested with their on-board diagnostics systems instead of with a tailpipe test, and make related changes to the sections of the rule on vehicle repair. Ecology also deleted outdated language in the rule, and added clarifications to make the rule easier to understand and more consistent.
What Will This SIP Revision Do? Ecology is requesting two actions to revise the SIP:
1. Ecology requests that EPA approve the nine sections of the rule that ecology has revised since EPA last approved the rule. These sections are: WAC 173-422-020 Definitions, 173-422-030 Vehicle emission inspection requirement, 173-422-031 Vehicle emission inspection schedules, 173-422-060 Gasoline vehicle emission standards, 173-422-065 Diesel vehicle exhaust emission standards, 173-422-070 Gasoline vehicle exhaust emission testing procedures, 173-422-075 Diesel vehicle inspection procedure, 173-422-190 Emission specialist authorization, and 173-422-195 Listing of authorized emission specialists.
2. Ecology requests that EPA remove previously approved fee provisions from the SIP, because these provisions are not appropriate for inclusion in the SIP. The parts of chapter 173-422 WAC that are to be removed from the SIP are:
• | WAC 173-422-130 Inspection fees. |
• | The words "twelve or less dollars" in WAC 173-422-160 Fleet and diesel owner vehicle testing requirements. |
