Reducing Odorous Air Contaminants in Metro Vancouver

Boundary Bay Airport Control Tower

Many people don’t know that the Metro Vancouver Regional District is responsible for regulating air quality in our region.

The Regional District is in the process of updating its air quality fee bylaw, which sets fees based on the amount of regulated air contaminants released. The goal of the bylaw is to use these fees to encourage facility owners to reduce the contaminants they release into the air.

Not surprisingly, the top air quality complaint the regional district receives is about odours. The following graph shows the number of complaints received since 2011.

The jurisdictions with the most complaints are consistently Vancouver, Burnaby, Delta, Richmond, Surrey, and the Township of Langley. Interestingly, complaints from Vancouver have been steadily increasing, while those from other jurisdictions have been fairly consistent.

Given the number of complaints around odours, the proposed updated bylaw includes a list of odorous air contaminants and associated fees with the aim of reducing the release of these substances.
