Carbon Monoxide and Ozone Maintenance Plans

The Southwest Clean Air Agency has updated both the Carbon Monoxide Maintenance Plan and the Ozone Maintenance Plan. The Vancouver Air Quality Maintenance Area (AQMA) meets the current air quality health standards for both carbon monoxide and ozone. Each plan shows that the Vancouver AQMA is expected to maintain levels well below the federal health standard until 2016 with existing control strategies.
