Air Pollution vs. Air ToxicsAir Pollution - carbon monoxide,
ozone, particulate matter (PM2.5 and PM10), nitrogen oxides, sulfur oxides and lead
Air Toxics - air pollutants known or suspected to cause cancer or other serious health problems
Red text indicates levels of concern for Portland

Air ToxicsInclude: diesel soot, benzene,
polycyclic aromatic hydrocarbons (tar-like by-products from auto exhaust and other sources), and metals including manganese, nickel, and lead
Sources: cars and trucks, all types of burning (including fireplaces and woodstoves), businesses, and consumer products such as paints

Air Pollution in the Press• Bullseye Glass, Southeast Portland• Mercury breaks story, February 2016• DEQ – Cease and desist – May 2016 (lead)• Issues - Lead, cadmium, chromium and
arsenic• Cadmium levels raised potential cancer risk
from 1 in 1,000,000 to 1 in 10,000• Uroboros Glass, North Portland• Cadmium Hot Spot – ceased using colored
glass• Precision Castparts, Southwest Portland• Nickel Hot Spot

What we learned: Portland’s air is dirtier than we thought As of March 2016, Portland had one permanent
air quality monitor (more monitors now) The state of Oregon knew about some of the
issues for over a year, and has been receiving complaints about Bullseye since the 1980’s
Elevated levels of metals have potentially increased cancer to 1 in 5,000 (want 1 in 1,000,000)
NO permit required for heavy metal discharge for glass manufacturing facilities

The Positive Side: Urban moss being used to reveal
“hot spots” throughout Portland with concentrations of toxic heavy metals like cadmium, arsenic, nickel, and lead◦Been using moss and lichen for years ◦Forest Service researchers in Portland
are the first to do so on a city-wide scaleTwo top DEQ officials, including the
department director stepped down

The Portland Air Toxics Solutions project produced a technical study that included an analysis of available monitoring information and computer model estimates of Portland’s expected pollutant levels in the year 2017.

Moving Forward….Steps for St. Johns Air Quality Improvements Meet with Eastside Air Pollution – formalize SJ plan Permit list
◦ Active permits – status of these permits Current, violations, etc.
◦ Facilities in need of permits – prioritized◦ Research current requirements for permits
Stationary sources Mobile sources
Testing and available technology◦ Mobile sources◦ Stationary sources◦ Related Costs and time required
Community Information / Updates◦ Write-ups review◦ Forums / Work-groups
