Duration of Burn: The release of smoke must ease after 72 hours; if smoke continues to be released after this length of time, the fire must be extinguished
Smoke Free Periods: Open burns must be separated by a smoke free period of 15 days
Venting: Open burns may only take place when the Venting Index is forecast to be "GOOD" on the day the burn is initiated and at least "FAIR" for the following day
The Venting Index is available at http://www.env.gov.bc.ca/epd/epdpa/venting/venting.html or by phoning 1-888-281-2992. Regardless of the venting index, fires must not be initiated if local airflow would likely cause smoke that negatively impacts nearby population areas.
