DEQ Issues Air Pollution Advisory for Northern Willamette Valley through Saturday, Jan. 29
DEQ asks residents to limit wood burning
In coordination with the National Weather Service, Oregon DEQ and Washington’s Southwest Clean Air Agency have issued an air pollution advisory for the northern Willamette Valley and Clark County. The agencies urge residents in the following areas to not burn in woodstoves and fireplaces because of poor air quality conditions: Clark, Multnomah, Washington, Clackamas, Polk, Yamhill and Marion Counties.
The Lane Regional Protection Agency is monitoring conditions in Lane County and may also issue an advisory if pollution levels climb due to stagnant weather conditions.
The National Weather Service has issued an air stagnation advisory for Tuesday, Jan. 25 through Saturday, Jan. 29. Stagnant air is expected to trap smoke at ground level causing pollution to build up and become unhealthy, especially for sensitive people. At the beginning of the week conditions could remain stable with low levels of pollution buildup. However, there is a very real possibility conditions could worsen as the week progresses. Pollution levels are expected to worsen in the evening hours.
Fine particles in smoke can be inhaled deeply into lungs and damage delicate tissues. Exposure to particle pollution is linked to a variety of significant health problems, ranging from aggravated asthma to premature death in people with heart and lung disease.
This type of wintertime air pollution comes mainly from wood smoke. If burning wood is your only source of heat, burn hot fires using dry wood to lessen pollution. To reduce pollution people also should avoid outdoor burning, limit driving and avoid excessive vehicle idling such as a long morning warm ups or leaving the engine on while picking up the kids from school.
Health officials recommend that people who are sensitive to air pollution limit time spent outdoors especially in the evening and early morning when pollution levels are highest. Air pollution can trigger asthma attacks, cause difficulty breathing, and make lung and heart problems worse. Air pollution is especially harmful to children, people with heart and lung problems and adults age 65 and older.
In Washington’s Clark County, a Stage 1 Burn Ban is in place due to slower than expected clearing of high levels of air pollution from the last few days. Southwest Clean Air Agency staff will continue to monitor the weather and air quality conditions for signs of sustained improvement. At this point, the use of fireplaces and uncertified woodstoves is prohibited in Clark County (this includes fireplace inserts) unless it is your sole source of heat. Outdoor burning is also prohibited.
