Air Quality is a Growing Concern in the Comox Valley and across BC

Smoke from woodstoves and fireplaces is the most significant source of air pollution in the Comox Valley because of the valley’s frequent temperature inversions and calm winds in winter when people are burning wood as their primary source of heat.

Air Quality and Your Health

Since 2008, there has been an increasing body of evidence demonstrating that air quality in the Comox Valley is concerning due to high levels of fine particulate matter, especially during the fall and winter seasons when levels of this pollutant exceed national standards. Fine particulate matter is a pollutant that contains microscopic particles that can be inhaled and cause serious health problems especially in your lungs and your heart. There is no known safe level of fine particulate matter.

To help address air quality concerns in the region, the CVRD is working on two important projects/initiatives, both actioned under the Regional Growth Strategy: 

Airshed Roundtable Project

Actioned under the Regional Growth Strategy service, the overall purpose of this project is to collaboratively develop and implement a Regional Airshed Protection Strategy to guide our actions moving forward. 

Airshed Roundtable Project

Wood Smoke Reduction Program

The Wood Smoke Reduction Program will help meet the Environmental Stewardship and Health and Wellness goals of the Regional Growth Strategy

Smart Woodstove Burning Practices

Keeping firewood dry, allowing enough time for it to cure before using, and  following good burning practices is essential to reducing smoke from wood burning. Smoky fires affect the health of our families, our neighbours, and our community. 

These videos by the Fraser Basin Council are also a good source of information:

Burning Regulations

Burning regulations may be different depending on your location. In areas that have a fire regulation bylaw, the Fire Chief manages restrictions on burning based on the current local conditions and the resources that are available to fight fire.

In areas that do not have a fire regulation bylaw, the Provincial regulations apply and are managed by the Province.

For more information on current burning restrictions in your area please contact your responding fire department. To identify your responding fire department and their contact information, please visit this interactive map.

Frequently Asked Questions
Where can I learn more about wood smoke’s impact on health?
What can I do to improve local air quality?

Burn responsibly. Burning wood poorly can pollute an entire neighbourhood. Smoke from a wood stove can seep into a neighbour’s house, even when their doors and windows are closed. Keeping firewood dry, allowing enough time for it to cure before using, and  following good burning practices is essential to reducing smoke from wood burning. 

The Wood Smoke Reduction Program provides opportunities to save money by offering rebates to replace old wood stoves with a cleaner heating option such as a heat pump or a gas, propane or pellet stove.

However you choose to heat your home, don’t let your house waste the heat - visit CleanBC Better Homes or talk to an Energy Coach to learn about saving money and saving energy.

Instead of burning yard clippings and branches from your property, consider delivering them to the Comox Valley Waste Management Centre where they will be blended into SkyRocket compost. If you are in an area where open burning of yard debris is permitted, and burning of this debris is the only option available to you, consider burning only on days when the ventilation index is “good”, and ensure your fire is extinguished and no longer releasing smoke before evening.  

What about open burning? What is allowed and when?

Please check with your responding fire department to confirm the current restrictions for your specific local service area.
To identify your responding fire department and their contact information, please view map.

What is the “ventilation index” and how does it affect air quality?

The ventilation index (or venting index) is a measure of the ability of the atmosphere to disperse airborne pollutants, and is based on current weather conditions. Smoke is considered an airborne pollutant. Weather conditions that result in temperature inversions, such as cool and clear fall or winter days, lead to a venting index that is typically considered “poor” – meaning the atmosphere is unable to disperse air pollutants, and they are trapped near the surface, resulting in compromised local air quality. 

The Province of BC has recently released an interactive map of the ventilation index forecast for areas throughout the province. The map, which includes the current ventilation index forecast for the Comox Valley, is available here.

What about wildfire smoke?

Unfortunately, wildfires and smoke are becoming a regular part of summer in British Columbia. We can’t predict when or where wildfires will happen, but we can prepare for smoky summers. Listed below are resources from the BC Centre for Disease Control.

Who is responsible for air quality management in the Comox Valley?

Managing air quality is a multi-jurisdictional challenge involving many levels of government as well as citizens. The provincial government’s Ministry of Environment (MoE) is responsible for implementing the air quality management system (AQMS) and also addresses air pollution through legislation, codes of practice, permits and standards. As part of AQMS implementation in the Comox Valley, the CVRD has worked with the MoE to establish an air quality monitoring station in the Comox Valley.

Many areas in the Comox Valley have bylaws in place that regulate burning activities. Many of these bylaws are intended to reduce the risk of fire and resulting property damage, though they also provide air quality benefits. For instance, depending on where in the Comox Valley you reside, backyard burning may be prohibited, or may require a permit.

What is local government doing to improve air quality?

Wood Smoke Reduction Program

The CVRD, with funding from the Ministry of Environment, BC Lung and Island Health, is offering rebates for switching an old wood-burning appliance for a cleaner heating option such as a heat pump or a gas, propane or pellet stove. Further details are available here.

Airshed Roundtable Project

Actioned under the Regional Growth Strategy Service, this collaborative multi-stakeholder initiative will develop and implement a Regional Airshed Protection Strategy for the Comox Valley. Further details are available here.

Air Quality Emissions Inventory

The CVRD partnered with the Ministry of Environment to conduct a particulate matter emissions inventory for the Comox Valley for the baseline year of 2015. Some commentary on road dust emissions was subsequently issued in 2019 to clarify the degree to which road dust contributes towards fine particulates in the Comox Valley, and that commentary is available here.

Air Quality Elected Officials Forum

On April 4, 2017 the CVRD hosted an air quality elected officials forum, where presentations from a variety of experts in the air quality field were brought forward for consideration. Minutes of this forum, including presentations are available here.

Where can I find more information about air quality?

BC Air Quality homepage – includes information on air quality advisories, current air quality health index (AQHI), current venting index & links and updates to provincial air quality legislation. 

The Province of BC – includes information about Pollution Sources, Emissions, Smoke & Burning, and Air Quality.

The British Columbia Lung Association – the BC State of the Air Report is published annually by the BC Lung Association’s Air Quality and Health Steering Committee. It provides a snapshot of current air quality issues across the province.
