Comparison: State v. Federal
• Rules. Many of the federal mobile source emissions standards are applicable and in effect in Washington, and the state adopted the California low emissions vehicle (LEV) standards. Washington administers its own vehicle inspection and maintenance program and a seasonal oxygenated gasoline program.
• Administration and enforcement. WDOE's Air Quality Program administers and enforces the state mobile source requirements.
Emissions controls required by the state and federal government are designed to reduce emissions from motor vehicles. However, the effectiveness of the controls is substantially reduced through deterioration, maladjustment, and tampering. The Washington motor vehicle emissions testing program is intended to encourage appropriate vehicle maintenance and repairs in order to reduce air pollution.
