Provincial Air Quality Objectives for Nitrogen Dioxide

The B.C. Ministry of Environment and Climate Change Strategy proposes to adopt new Provincial Air Quality Objectives (AQOs) for Nitrogen Dioxide (NO2). Provincial air quality objectives are non-statutory limits that serve as benchmarks for air quality planning, permit applications, authorizations, and air quality advisories. Guided by the Provincial Framework for Developing Provincial Air Quality Objectives, the review recommends adopting new objectives based on the 2020 Canadian Ambient Air Quality Standards (CAAQS) for NO2. This includes adopting more stringent one-hour and annual objectives and changing the calculation method for the one-hour metric.
