Air monitoring: DEQ conducted monitoring for a full set of air pollutants, including volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), carbonyls, particulate matter, and heavy metals at a monitoring site at SE 45th and Harney from June 2016 to December 2017. DEQ is preparing a report on the air toxics data set and aims to finalize it in summer 2019.
Air permits: DEQ is currently working on air quality permits for PCC’s Large Parts Campus, Small Parts Business Operations, and Deer Creek Campus. Because of the complexity of these permits, the renewal process will take some time, and there is not currently a timeframe for anticipated public notice.
DEQ installed three air monitors around Precision Castparts to collected information about heavy metal pollutants between April and October 2016. The first set of data from air monitors placed near Precision Castparts Corp. in spring 2016 showed levels of heavy metals nickel, hexavalent chromium and arsenic above annual benchmarks.
One of the monitoring sites, at 45th and Harney, was converted to a full air toxics monitoring site in June 2016 to collect data about other pollutants—volatile organic compounds, polynuclear aromatic hydrocarbons, carbonyls, and particulate matter—in addition to heavy metals.
Results of soil sampling completed in the area around the Precision Castparts Corp. (PCC) Harney Drive facility in southeast Portland indicate that residents living near the facility are at low risk of short-term health problems from exposure to heavy metals in soils in the area.
