Precision Castparts Structural Large Parts Campus

EHAP is in the process of developing a Public Health Assessment (PHA) for the community surrounding the Precision Cast Parts (PCC) facility in southeast Portland. The PHA will evaluate environmental data collected by the Oregon Department of Environmental Quality (DEQ), to better understand the long-term health risks before and after the facility took steps to reduce their emissions.

EHAP is currently convening a series of three Community Advisory Committee (CAC) meetings, made up of residents who live and/or work within a half mile of PCC. These meetings have been designed to:

  1. Receive input and feedback from the local residents into the exposure assumption and scenarios that will be used in the PHA.
  2. Educate participants about the PHA process and build community capacity in environmental health.
  3. Develop relationships with local residents, to help build trust in the long-term PHA process.
  4. Identify the most relevant way of communicating to the broader community about the PHA and the conclusions and recommendations that will result from the process.
  5. Ensure that community concerns are highlighted, incorporated and addressed through the PHA process.

Background Information

In 2013, the US Forest Service started using moss to understand air quality across Portland. In February 2016, the moss data showed significant heavy metal hot spot areas across the city, including areas near various glass manufacturing facilities and the Precision Cast Parts Structural Large Parts Campus. PCC is a large metal foundry operating since the 1950's, bordering Johnson Creek. At this location, the company makes parts for the aerospace industry, using nickel, titanium, aluminum and steel alloys. To validate the moss data and determine if heavy metals associated with emissions from PCC may be a risk to human health, the Department of Environmental Quality (DEQ) began air monitoring and collected soil samples at properties next to PCC. These efforts complement existing activities by DEQ, including clean-up activities and permitting.


The release of a document for public comment is estimated for 2018.
