Wood Smoke Ordinance would exempt wood-only households, low income, pellet stoves

Multnomah County Public Health officials joined Commissioner Dr. Sharon Meieran Thursday night at a community meeting in Linnton to discuss a proposal to limit wood burning on winter’s worst air quality days.

The ordinance would be in effect each year from Oct. 1 through March 1. Health officials would look to the National Weather Service to help identify the worst air quality days — which occur on average three to five days per year — and issue a no-burn notice to residents through PublicAlerts, social media, on its website, through media and other means. The measure is being sponsored by Commissioner Meieran, an emergency room physician, and Commissioner Jessica Vega Pederson.

The following is a Q and A based on the concerns of residents who live on forested properties along Old Germantown Road and met Nov. 16 with County officials in Linnton.

Won’t this harm people who need wood stoves for heat during cold months?

The ordinance would exempt anyone using wood as their sole source of heat or who needs to burn wood because their furnace is broken. Anyone who is low-income would be exempt, as well as anyone using an Environmental Protection Agency (EPA)-approved wood pellet stove. Enforcement would be complaint-driven. A large part of the program is educational. The first and second violation would trigger a certified mailing with educational materials about clean burning and pollution. Fines would not begin until at least the third violation.

“That’s a legitimate worry that we tried to address,” said Commissioner Meieran, who represents residents above Forest Park. “We’re not trying to take peoples’ wood stoves away.”

Inversions can last for a long time, so aren’t we really talking about burn bans that could last days?

“An inversion is one condition that might perpetuate a curtailment, but it’s not the sole,” said Matt Hoffman, who coordinates air pollution policy for the Health Department. “An inversion can trap pollution close to the ground, but the burning curtailments would also be determined by temperatures, wind speed and precipitation. Rain acts as a filter.”

Hoffman said the curtailment days would be rare. “For example, the last two winters, we wouldn’t have called a single curtailment day,” he said.

I support clean air, but an ordinance is just one more restriction. Why not try an advisory instead?

Multnomah County has issued burning advisories for more than a year, but there’s no evidence residents are volunteering to comply, Hoffman said. And there’s an urgency to keep pollutants below a certain level.

Following the Clean Air Act, the EPA began regulating six air pollutants including lead, ozone and particulate matter. The chemicals that contribute to particulate matter are often emitted from wood smoke, power plants, industry and automobiles. In recent years the county has come close to exceeding its federal cap on particulate matter 2.5.

Meieran said said she and her colleagues on the Board are trying to strike a balance that protects people with health risks, and protects the environment while avoiding federal interventions that might limit development.

“If you get to the point where you exceed the federal guidelines, the federal government comes in and puts curtailments and rules that are more restrictive than what we’re doing,” she said. “We want something that is effective and really easy on people, but addresses health risks because smoke is actually really dangerous for people,

Why not focus restrictions on industry and vehicle emissions? Those cause more pollution than wood burning.

Health officials say that industrial emissions account for less than one percent of the county’s overall excess cancer risk from air pollution. Wood smoke, on the other hand, accounts for 20 percent, on par with emissions from cars and commercial trucks. When analysts compare those proportions during winter months, wood smoke becomes the single greatest polluter of particulate matter 2.5.

Do any other governments in Oregon have this type of restriction?

Similar ordinances are in place all across Oregon, including rural Washington County, Hillsboro, Eugene, Klamath Falls, Oakridge, Lakeview, Medford, Pendleton and Grants Pass. Prineville is drafting an ordinance, and Burns and La Grande have voluntary curtailment programs.

How can the public comment on this proposal?

People are encouraged to submit comments and questions online, or attend an upcoming community meeting December 7, 9:30 – 11 a.m. at the Multnomah Building, 501 S.E. Hawthorne Blvd., in Portland

Concerned about wood smoke? Attend a meeting.

November 11, 2017

This past summer, residents of Multnomah County (and other parts of the state) breathed air heavily polluted by nearby forest fires. Many individuals had problems breathing and burning eyes and runny noses. The smoke-filled air was especially harmful to those with existing heart and lung diseases.

Many people don’t realize that burning wood in a fireplace or wood stove produces the same type of pollution as a forest fire, including tiny particles and gases that harm our health in many ways.* Along with diesel exhaust and industrial pollution, wood smoke is a major air quality concern in Oregon. Burning wood pollutes the air inside your home, increasing particle pollution and benzene by more than 25% and a particularly insidious pollutant known as polycyclic aromatic hydrocarbons by 400%. Wood smoke is also bad for your neighbors. The fine particles from wood burning cause outdoor air pollution and infiltrate even the most well-insulated and weather-stripped homes.

That’s why Multnomah County is proposing an ordinance to combat the wood smoke problem, asking people not to burn when temperature inversion events create unhealthy air conditions. The ordinance would be similar to those adopted in Washington, Jackson and Klamath counties and other local governments throughout the state, allowing exemptions for low-income households and those without an alternative source of heat.

Multnomah County is holding three meetings to educate residents about wood smoke and gather input on the ordinance. We encourage you attend.

November 6, 7:00-8:30 PM, Fairview Community Center, 300 Harrison St. Fairview, OR
November 16, 6:30-8:00 PM, Linnton Community Center, 10614 NW St. Helens Rd. Portland, OR
December 7, 9:30-11:00 AM, Multnomah Building, 501 SE Hawthorne, Portland, OR

OEC supports a combination of voluntary and regulatory measures to reduce pollution, and financial support to help low-income families replace their woodstove with a non-wood source of heat (preferable) or purchase a new certified woodstove (second best). Low-income families are often at a dual disadvantage: They not only can’t afford to change the way they heat their home, but are also more vulnerable to the health effects of wood smoke. Oregon household with an annual income of less than $15,000 consistently report higher percentages of asthma than all other income levels, and wood smoke worsens asthma. To help these families, OEC supports creation of a grant program at the state level that would help local governments implement wood stove replacement programs.

*The health impacts of wood smoke: According to the US Environmental Protection Agency, the cancer risk from a lifetime of exposure to wood smoke is 12 times greater than being exposed to the equivalent amount of cigarette smoke. Short-term exposure to wood smoke reduces lung function, especially in children; worsens lung diseases such as asthma, emphysema, pneumonia and bronchitis; aggravates heart disease; increases the risk of lower respiratory diseases; irritates eyes, lungs, throat and sinuses; and triggers headaches and allergies. It can even cause a fatal heart attack. Long-term exposure to wood smoke can cause chronic lung disease and bronchitis and increases risk of cancer and genetic mutations
