In Oregon, prescribed fire smoke is regulated by the Oregon Smoke Management Plan, which is overseen by the Oregon Department of Forestry (ODF) and the Department of Environmental Quality (DEQ). The plan is revisited every five years, in terms of both effectiveness and changing conditions. (This webpage provides links to the plan itself and related resources.) Since the plan was last revised in 2013, Oregon has experienced several severe wildfire seasons. Consequently, there has been a desire on the part of several communities, agencies and collaborative groups to change our smoke management rules in order to provide more flexibility and to allow for more prescribed fire, especially near communities where managing smoke has proven to be exceptionally tricky.
Currently, the Oregon Smoke Management Plan designates areas with relatively dense populations, such as cities, as Smoke Sensitive Receptor Areas (SSRAs). The overall objective of the plan is to maximize good fire while minimizing the smoke that enters SSRAs. Any ground-level smoke entering an SSRA is considered an “intrusion.” You can quickly realize that preventing intrusions, and therefore meeting the intent of the plan, is immensely challenging if you’re also juggling the objective of reducing wildfire risk in densely populated areas.
When we entered into the review process, several partners from around the state suggested changes to better align the plan with the standards in the Clean Air Act, which sets limits on particulate matter in the air based on scientific research, while also suggesting some flexibility in the rules for communities with a documented need to mitigate their fuels.
As the process moved ahead, it was clear that some of the suggestions regarding more smoke in the air made people who were looking at the issue from a public-health angle nervous, and for good reason. It is well documented that the fine smoke particles travel deep into people’s lungs and can cause serious health concerns. However, it was also clear to those stakeholders that wildfires are becoming increasingly deadly and destructive, and smoke from wildfires is typically more intense and longer in duration than prescribed fire smoke.
With these concerns in mind, ODF and DEQ put forward a revised rule (PDF, 2.08MB) meant to be slightly more lenient toward smoke than the current rule. ODF and DEQ held a series of public meetings across the state, including one in Bend (where I live and work) in which commenters expressed unanimous support for more prescribed fire. The window for public comment is now closed, and I’m pleased to say that most, but not all, of the comments favored the direction the proposed rules have taken. Numerous comments included statements acknowledging the need to use prescribed fire to proactively reduce fuels in the face of longer and hotter wildfire seasons.
The new rule, that hopefully will include the proposed flexibility, is set to be finalized in a series of meetings later this fall and winter. Hopefully, prescribed fire practitioners can utilize it to implement more controlled burns this coming spring.
