Washington Clean Air Act. Under the Washington Clean Air Act (Act), outdoor burning is generally prohibited in any area of the state where federal or state air quality standards are exceeded for pollutants from outdoor burning, in urban growth areas, or in certain large cities threatening to exceed state or federal air quality standards. Outdoor burning means the burning of material in an open fire or an outdoor container without controlling the fire or emissions.
Restrictions on outdoor burning do not apply to silvicultural burning to improve or maintain fire-dependent ecosystems for rare plants or animals. Outdoor burning may be allowed in the following instances:
Outdoor Burning Permits. The Department of Natural Resources (DNR), the Department of Ecology (Ecology), and certain political subdivisions such as counties, conservation districts, fire protection authorities, and local air authorities, may issue permits under the Act for a variety of outdoor burning activities in their respective jurisdictions, including agricultural burning and silvicultural burning. In general, permit fees for agricultural burning are set by the permitting agency, in consultation with a task force, subject to certain maximum fees for field and pile burning.
DNR is responsible for issuing and regulating permits and associated fees for certain burning activities on lands under its fire protection authority to: (1) abate and prevent fire hazards; (2) facilitate forest firefighting instruction; and (3) enable burning operations to improve fire-dependent ecosystems and otherwise improve state forestlands. DNR must encourage more intense utilization in logging and alternative silviculture practices to reduce the need for burning, and encourage landowners to develop and use alternative acceptable disposal methods subject to the following priorities:
Definitions. Flame cap kiln means an outdoor container used for the combustion of natural vegetation from silvicultural or agricultural activities that meets the following requirements:
Silvicultural burning includes combustion of natural vegetation from silvicultural activities.
Outdoor Burning Permits. For the purposes of agricultural burning permits, agricultural burning includes the combustion of natural vegetation from agricultural activities in portable flame cap kilns, provided that the biomass does not contain any prohibited materials, such as garbage, dead animals, petroleum products, or other specified substances.
DNR may assess permit fees for combustion of natural vegetation from silvicultural activities in portable flame cap kilns.
The use of portable flame cap kilns is added to the list of priorities under which DNR must encourage landowners to develop and use in logging and alternative silviculture practices to reduce the need for burning.
Other. Legislative intent language is provided.
The committee recommended a different version of the bill than what was heard. PRO: This is an important bill because there is a lot of forest biomass that needs to be removed and it is often burned with no benefit. This provides value to a lot of logging slash, and value that helps the environment. Biochar is an emerging technology and it is promising. Ecology is lagging a bit in permitting these biochar units. The biochar kilns we use are not burn barrels, but Ecology defines them as such. Burning slash in biochar units prevents catastrophic wildfires. The ring of fire kiln is essentially a wind screen around a kiln. It is a micro kiln emitting much less particulate matter than an open burn. Biochar is the future in sustainability. It takes a byproduct and creates an economic use. This is scientific and complicated, but if we can figure it out, it is a big win for our forests. It is easier to do a prescribed burn than to get a biochar unit permitted.
OTHER: We do not have a position on the bill but want to provide technical information about what is happening in Oregon. Air curtain incinerators show decreased emissions reductions relative to open burning. We have significant concerns because biochar production releases fine particulate matter and toxic pollutants. To comply with existing state and federal law, biochar production requires submittal of a new source permit application to Ecology or a local air agency. Biochar units using pyrolysis or an air curtain incinerator require an air quality permit under federal rules. DNR does not have delegated authority from the EPA or expertise to permit these units. We have concerns and questions with the definitions in the bill.
PRO: Senator Kevin Van De Wege, Prime Sponsor; Kelpie Wilson, Wilson Biochar, LLC.; Jill Silver, 10,000 Years Institute; Jake Dailey, U.S. Rake Force; Tony Craven; Jason Callahan, Green Diamond Resource Company.
PRO: Part of the solution to preventing catastrophic forest fires is to remove and eliminate flammable material on the forest floor. Utilization of flame cap kilns is cleaner and safer than open slash burning. This process produces a carbonaceous byproduct called biochar, which will allow us to go forward in developing a small scale carbon market. This is a huge step forward in managing hazardous fuel.
This bill would provide a helpful mechanism for small forest landowners in the state to reduce hazardous fuel that may lead to forest fires. The frequency and duration that burning can be used is limited. Using flame cap kilns reduces burn time and is a cleaner method to eliminate potentially dangerous fuel. This bill will hopefully help to bring down the number of forest fires.
