On Wednesday, May 15, at around 12:40 p.m. local time, a truck carrying a Nitric and Hydrofluoric acid mixture leaked onto the ground at Precision Castparts’ facility in Milwaukie. Employees were evacuated and Clackamas Fire and Portland and Gresham HazMat teams were on scene. No injuries have been reported.
DEQ has been assessing the site. There are no issues with air quality. There was some release to Precision Castparts’ stormwater system, which discharges to Johnson Creek. Precision Castparts treated and recirculated the water with caustic to bring the pH up. Oregon Department of Fish and Wildlife conducted spot checks on margins and backwaters along Johnson Creek, but no dead fish were observed. DEQ instructed Precision Castparts to collect samples of the discharge water at the outfall and we expect results within a week or two.
On Thursday, May 16, a DEQ Water Quality specialist conducted a site inspection and evaluated the stormwater system at Precision Castparts. He determined there should be no environmental harm, as long as staff followed the established stormwater pollution control plan. He is waiting on an official report from Precision Castparts to understand exactly how they responded to the incident.
The release was apparently the result of a failure on a sampling port on a chamber in the tanker, but investigation into the cause is ongoing.
This update received from Daniel Newberry, Executive Director, Johnson Creek Watershed Council.
Community members who need OHA publications like the Public Health Assessment (PHA) in other languages, large print, braille, or other alternative formats can make this request by contacting the Public Health Division at 971-673-0977 or 971-673-0372.
Please join the Oregon Health Authority (OHA) for a community meeting on the Precision Castparts Corporation Public Health Assessment (PHA) findings. OHA recently released a PHA which found low health risks from contaminants detected near the facility. Environmental health experts will provide an overview of the findings and process and answer questions.
Schedule: 6:00pm-7:00pm: Open House
7:00pm-8:30pm: Presentation and Q & A Session
BDNA NOTE: A representative from the Bureau of Planning and Sustainability will be at our August 2nd BDNA general meeting to talk about and answer questions for this project.
The E-zone Map Correction Project will adjust the location of Portland’s environmental overlay zones to match locations of existing streams, wetlands, steep slopes and vegetation as required by the new Comprehensive Plan. The environmental overlay zones protect natural resources that are essential for watershed health. The environmental overlay zones were applied to properties through officially adopted conservation plans around Portland starting in 1989 and completed in 2003. With the new Natural Resources Inventory in 2012 it became obvious that some resources that are supposed to be protected (like stream segments) are not, while other lands have regulations but no natural resources. This project will correct that. If your property will be considered for remapping as part of this project, you will receive a postcard in the mail. The postcard will let you know where you can get more information about potential changes on your property.
