Air Quality
Air quality is an environmental issue of high priority since it can have a profound effect on quality of life. The Lower Fraser Valley Airshed (LFVA), in which Chilliwack is located, is a confined airshed because air becomes trapped in the valley due to the surrounding mountains. As a result, the airshed is susceptible to the build-up of contaminants. Therefore, protective measures are required to reduce potential impacts on human health, visibility and the environment. The LFVA overlies the Greater Vancouver Regional District, the Fraser Valley Regional District and part of Whatcom County in Washington. The LFVA is shown by light green on the map below (map source: 2000 Emission Inventory for the LFVA).
Air quality in Chilliwack
Air quality is generally very good in the Chilliwack area. However, during the summer months concerns arise about the possible impacts of deteriorating air quality. These concerns include human health, lower visibility and harm to the environment.
Air quality in Chilliwack is a function of both human and environmental factors. Vehicle, industrial and agricultural emissions are the greatest human factors. Weather conditions also influence Chilliwack’s air quality, as wind from the west transports pollutants up the valley.
The major pollutants which affect Chilliwack’s air quality include:
• Nitrogen oxides (NOX) and Sulphur oxides (SOX) – The major sources include motor vehicle and industrial emissions. These compounds are related to respiratory problems, acid rain and smog.
• Particulate matter (PM10, PM2.5) – Agricultural activity produces a large amount of dust, especially during dry periods. Fine particulate matter (PM2.5) is also a product of the reaction between ammonia (NH3) and NOX in the atmosphere.
• Ground-level ozone (O3) – Ground-level ozone forms from the reaction between NOX and volatile organic compounds (VOCs) in the presence of sunlight and warm temperatures.

Waste incineration is an important issue currently facing the Vancouver and The Fraser Valley. Currently Metro Vancouver is considering a plan which would lead to over half a million tonnes of garbage being incinerated every year. You are encouraged to consider weigh all waste management options available.

Idle-Free
|
|
In order to reduce greenhouse gas emissions and smog causing pollutants, the City has launched an "anti-idling" campaign. This campaign involves both policy and public education components. In September 2004, City Council adopted a policy that will eliminate all unnecessary vehicle idling within municipal fleets. |
