Air Curtain Incinerators

What is an Air Curtain Incinerator?

Air curtain incinerators are devices that burn wood waste like trees and brush. ACIs have an insulated box to burn the wood waste and a fan powered by a diesel engine that blows a curtain of air over the box. Oregon uses ACIs for both wildfire cleanup and fire prevention efforts. ACIs are an alternative to traditional open burning and produce less harmful smoke and particulate matter.

There are two types of air curtain incinerators; one ACI produces biochar and the other produces ash. Both types of ACIs are powered by a diesel engine that must meet the cleanest Tier 4 engine standards available on the market. If you would like additional information, please contact Max@lrapa.org.

What is emitted from an ACI?

Compared to traditional outdoor burning of wood waste, air curtain incinerators emit lower levels of air pollutants including PM2.5 and NOx. ACIs burn more efficiently and produce significantly less smoke than traditional outdoor burning.

DEQ and LRAPA have created a list of authorized and prohibited materials for use in ACIs. Toxic air pollutants from ACIs come from the wood itself. The most concerning pollutants are metals like manganese. Manganese is naturally occurring in soil and is taken into the tree through the roots. The metals can be released into the air when the wood is burned. The emissions from the diesel engine that powers the fan are also assessed as part of an LRAPA air permit.

How does the Cleaner Air Oregon program estimate health risk?

In Oregon, facilities are required to evaluate the health risk from toxic air pollutants. To do this, facilities first estimate the types and amounts of toxic air pollutants emitted. Next, facilities determine the risk from those toxic air pollutants to adults and children living, working, or going to school nearby. This is done through dispersion modeling that estimates how much of a given pollutant a person nearby may breathe in based on distance, time and amount.

LRAPA compares the dispersion modeling estimates of risk with Oregon’s established health standards. If the facility’s risk is higher, LRAPA requires the facility to lower their emissions.

An ACI is operating near me. What can I expect?

If an ACI begins operating near you, you may see brief periods of smoke when the ACI first turns on and when the operators load new material. You may briefly smell burning wood. Noise from the device is limited to the diesel engine and blower fan. The vehicles used to load the ACI may also create noise.

The ACI should not be a constant source of heavy smoke. This may indicate that it’s not being operated properly.

ACIs Outside of Lane County

The following companies are currently permitted by DEQ or are applying to DEQ to operate in Oregon and outside of Lane County. See DEQ’s ACI webpage. If a company is listed as ‘portable’ and is permitted by DEQ, they must obtain a permit from LRAPA prior to moving into a new location in Lane County.

What Other Rules Apply to an ACI?

There are many safety protocols the operator of an ACI must follow to protect those nearby. The ACI can’t operate if the local fire department or Forest Service has banned burning, an air stagnation advisory is in place or the Air Quality Index is 100 or greater. The operators must be trained by a certified operator and they must follow all safety actions recommended by the manufacturer.

If you have concerns about the operation of an ACI near you, please contact LRAPA.

LRAPA monitors air quality throughout Lane County with eight regulatory-grade monitors and over 90 commercial-grade air sensors. Air Quality Index values are updated hourly.

Find the current air quality, look up the closest monitor to you, and learn more about the Air Quality Index (AQI) on the Current Air Quality Page.

LRAPA regulates the burning of wood and yard debris, known as “outdoor burning,” in Lane County. LRAPA also enforces home wood heating – such as fireplaces and wood stoves – opacity ordinances for the cities of Eugene, Springfield and Oakridge. Seasonal and daily restrictions can exist for both forms of burning.
Check to see if there are any active burning curtailments in effect on the burning restrictions webpage.
Learn More

Burning wood in fireplaces and wood stoves for heat is a common practice in Oregon. However, wood burning creates particulate matter, which is Lane County’s most common form of pollution, and can dramatically degrade air quality during periods of air stagnation.

LRAPA issues daily green, yellow, and red burn advisories from October 1 through May 31, based on air quality conditions. These advisories permit, limit, or restrict the use of fireplaces and wood stoves.

Outdoor burning is the disposal of woody yard material by burning it. Burning rules vary throughout Lane County depending on location, size of property, weather forecast, and fire danger conditions. LRAPA rules also limit the type and quantity of debris which can be burned.

Cleaner Air Oregon is a state-wide program designed to regulate emissions of Hazardous Air Pollutants. New facilities beginning operation, or current facilities called into the program by LRAPA, are required to quantify all air toxic pollutants emitted from the facility. Then a computer model determines how emitted pollutants move across Lane County, to understand who is exposed to the pollutants and in what amounts. With that information a health risk assessment is conducted of that exposure.
