State tells glass factory to cut metal emissions after spike
Posted September 16
PORTLAND, Ore. — A Portland glass-making company under scrutiny for poisonous metal hotspots has been directed by state officials to reduce metals usage again after a recent spike in emissions.
The Oregon Department of Environmental Quality and the Oregon Health Authority told Bullseye Glass in a letter Friday that selenium concentrations in the air jumped in a reading taken Sept. 6.
Officials say the level was above the level at which negative health effects such as respiratory irritation could occur.
The letter sought confirmation of the company's commitment to limit selenium use, to use it in pollution-controlled furnaces and to look into what caused the spike.
A message to the company for comment wasn't immediately returned.
State regulators announced in February they discovered hazardous levels of cadmium and arsenic in the air near Bullseye Glass, which prompted the company to suspend use of the metals.
