Concordia neighborhood is near an industrial area and a busy industrial truck route. That is likely to cause dangerous industrial air pollution for neighbors because human health is not considered currently as a factor in the regulation of these industries by the Oregon Department of Environmental Quality (DEQ).

Since Gov. Kate Brown’s Cleaner Air Oregon rulemaking process started recently, DEQ has applied human-health regulation only to new industries coming to Oregon. Regulation of existing Portland-area industry has been limited so far to four of the most dangerous factories — all too far away to affect Concordia.

According to the Oregon Department of Transportation (ODOT), which measured industrial truck 24-hour counts in Concordia, industrial truck activity throughout the neighborhood is very low. Samples taken on Lombard in 2018 found just 17 or 18 trips per day. The exception is on Columbia Boulevard, which was much higher — 380 industrial truck trips per day.

Portland Bureau of Transportation (PBOT), however, sampled at 52nd Avenue and Columbia in July 2017 and recorded 2,549 truck trips in a day. That’s the second highest industrial truck count taken in over a decade of Portland-area samples taken by both agencies. Industrial trucks are all diesel-fueled. California reported that diesel particulate causes 70% of cancer risk from all airborne carcinogens combined, and the state banned unfiltered diesel trucks.

A Portland Clean Air analysis of ODOT and Oregon Driver and Motor Vehicle Services records found 75% of Portland area trucks are still unfiltered. Diesel particulate is unusually tiny – so small that airborne particles enter the bloodstream easily from the lungs and are transported to every organ, including the brain.

Heavy metals and volatile organic compounds (VOCs) attach readily to the surface of these particles and are absorbed throughout our bodies to cause dozens of short-term and long-term symptoms.

When airborne diesel particulate concentrations are extremely high, this results in black or gray dust on doors and windows. Find more information at PortlandCleanAir.org.

Seventeen industries with relatively small quantities of industrial emissions comprise the industrial area to the north of Concordia. DEQ considers all but three of them small enough to not even need a permit. Three have lower-level air pollution permits.

If you smell industrial solvents, it could be them – or a leaking residential oil tank, tar from a roofing job or some other source.

We are working with the Concordia Neighborhood Association to monitor diesel particulate and VOC emissions using bike-mounted devices that take readings every two seconds. These require twohour-long bike rides to reach each street in the area.

The data are collected and made into a color-coded geographic information system map showing airborne concentrations of VOCs and airborne particulate one micron and smaller in diameter.

Volunteer bike riders are needed for this research. Please email Greg@PortlandCleanAir.org to volunteer for a ride – or if you have any questions about your exposure and/or what can be done about it.

Greg Bourger and Portland Clean Air works with 76 Portland neighborhood associations, churches and other local groups to assist stakeholder negotiations with the most dangerous unfiltered industrial smokestacks and diesel trucks.

In Portland, neighborhood emergency teams (NETs) are most often associated with earthquake preparedness and response.

Although that is often what draws people to volunteer and train for NET – and is a focus in training – NETs are also ready to respond to all kinds of large and small emergencies. For instance, in the past year, some of the ways NET members have volunteered include:

• Maintaining a safe perimeter around downed power lines until power company employees arrive
• Controlling traffic and monitoring patients at COVID-19 vaccination clinics
• Staffing warming shelters in the winter and cooling shelters in the summer
• Collecting donations of personal protective equipment and other supplies for first responders in the early stages of COVID-19
• Staffing evacuation shelters during Oregon’s 2020 forest fires
• Organizing and volunteering for mutual aid groups, including organizing and distributing food donations and other supplies
• Assisting at the Multnomah County Emergency Coordination Center with COVID-19 operations

Team members have also participated in thousands of hours of advanced training over the last year. Many of these topics are those associated with traditional disaster preparation, such as first aid and maintaining post-earthquake sanitation.

Other types of training have been made available to NETs in response to the needs of Portland’s population and the evolving role of NETs to assist in our communities. These trainings have covered topics such as diversity and equity in leadership, coping with trauma, building community resilience and building cultural competency.

There are currently over 2,000 active NET members on 87 neighborhood teams across Portland. Joining NET is a straightforward, multi-step process that starts by visiting PortlandOregon.gov/pbem/31667 to sign up.

In-person classes are suspended for the time being, but it’s possible to do the majority of the free training online. You’ll be able to complete the final – and most fun – hands-on portion of the training when it is safe to conduct in-person classes again.
