St. Johns air quality presentation

  1. 1. St. Johns Air Quality 2016
  2. 2. Air Pollution vs. Air Toxics  Air 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 2
  3. 3. Air Toxics  Include: 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 3 Source:
  4. 4. Sources of Air Toxics 4 Source:
  5. 5. 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 5
  6. 6. USA Today – Smokestack Effect 6 Source: /smokestack/index
  7. 7. USA Today – Smokestack Effect  George Middle – 1st Percentile ◦ The air is worse at 437 schools across the nation  Sitton Elementary – 3rd Percentile ◦ The air is worse at 2,185 schools across the nation  James John Elementary – 3rd Percentile ◦ The air is worse at 2,350 schools across the nation 7 Source: /environment/smokestack/school/74416
  8. 8. 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 8 Source: things-you-need-to-know-about-portlands- toxic-air-situation/
  9. 9. 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 scale  Two top DEQ officials, including the department director stepped down 9 Source: things-you-need-to-know-about- portlands-toxic-air-situation/

  11. 11. 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. Air Toxics by Pollutants – Diesel, Acrolein, PAH-15 11 Source: smaps.htm

  15. 15. North Portland Update  As of September 2016: ◦ Moving air monitoring station from North Roselawn Street to a site approximately one fourth mile to the southwest at the Humboldt School property, 4915 N Gantenbien Ave. ◦ The new site is in an open area near playgrounds, schools, and high density housing. ◦ Moved and operational by October 2016 15 docs/NPortlandmonitors.pdf
  16. 16. 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 16
