Air Quality Advisory Ended for the Comox Valley
December 15, 2017
Update, Friday, December 15: "The Ministry of Environment and Climate Change Strategy in collaboration with Island Health has ended the air quality advisory for Courtenay as air quality has improved.
Open burning may now be conducted without a permit or approval from the Ministry of Environment and Climate Change Strategy provided that the activity complies with the Open Burning Smoke Control Regulation, Environmental Management Act.
All open burning must also comply with Municipal open burning bylaws where a bylaw exists.
For more information on current air quality and to obtain the Venting Index, see: www.bcairquality.ca. Please note that the ventilation indices drop to poor after sunset."
Previously: "The Ministry of Environment in collaboration with Island Health has continued an Air Quality Advisory for Courtenay because of high concentrations of fine particulates that are expected to persist until weather conditions change.
Persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. Staying indoors and in air conditioned spaces helps to reduce fine particulate exposure. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease.
Open burning restrictions are now in effect for the Comox Valley within 15 kilometres of Courtenay City Hall until Friday, December 15. No new fires may be initiated and no additional material may be added to existing fires.
For more information on burning restrictions, see the section below entitled ‘Mandatory Emission Reduction Actions.’ For more information on current air quality, see: www.bcairquality.ca
Tips to reduce your personal health risk.
- Avoid roads with heavy vehicle traffic and areas with wood smoke
- Continue to manage medical conditions such as asthma, chronic respiratory disease and heart disease. If symptoms are bothersome, seek medical attention. Residents with asthma or other chronic illness should activate their asthma or personal care plan.
- Use common sense regarding outdoor physical activity; if your breathing becomes difficult or uncomfortable, stop or reduce the activity.
- Maintaining good overall health is a good way to reduce health risks resulting from short-term exposure to air pollution.
- Stay indoors, keep windows and doors closed and reduce indoor sources of pollution such as smoking, vacuuming and use of wood stoves.
- Run an air cleaner. Some room air cleaners, such as HEPA filters, can help reduce indoor particulate levels provided they are the right size for your home and filters are changed regularly.
- Take shelter in air-conditioned buildings which have large indoor volumes and limited entry of outdoor air.
Mandatory Emission Reduction Actions
- As pollution may occur from open burning, the Director has suspended the exemption in the Open Burning Smoke Control Regulation (Sections 2(i) and 4(2)(a)) that allows for open burning of debris to occur without a permit or approval from the Ministry of Environment. For the next two days, no new fires may be initiated in the Comox Valley within a 15 kilometre radius from Courtenay City Hall and pursuant to Section 4(2)(c) of the Regulation, no additional material may be added to existing fires. Contravention of these provisions may be subject to a fine under the Regulation.
Voluntary Emission Reduction Actions
- Avoid the use of wood stoves and fireplaces unless used as the sole source of residential heat.
- Where wood stoves or fireplaces are the sole source of residential heat, burn well-cured dry wood, and ensure an adequate supply of combustion air.
- Avoid backyard burning until weather conditions improve.
- Reduce the use and idling of vehicles.
- Fine particulate (PM2.5) concentrations averaged over 24 hours, were 28 micrograms per cubic metre (μg/m3) as of 8:00 AM this morning. This exceeds the provincial air quality objective of 25 μg/m3.
- Elevated PM2.5 concentrations are resulting from poor dispersion associated with calm winds over the area. These stable conditions are expected to persist until weather conditions change.
- Fine particulate concentrations are expected to be higher during the evening, overnight and early morning hours and should improve during the midafternoon hours.
