The Oregon Department of Environmental Quality has issued a $9,829 civil penalty to a unit of Precision Castparts Corp. for failing to monitor polychlorinated biphenyls (PCBs) and polynuclear aromatic hydrocarbons (PAHs) in its stormwater discharges.
The violations occurred two times at seven sampling points at the metals company's main plant in Southeast Portland during the 2015-16 year, DEQ reported Wednesday.
That plant is located at 4600 S.E. Harney Drive, near Johnson Creek.
During 2015 and 2016, PCC Structurals, a unit of Precision Castparts, designed and installed a stormwater treatment system to comply with permit requirements and to remove contaminants of concern, including PCBs, under a voluntary cleanup program, DEQ says.
