Elevated and possibly unsafe levels of metals have been found in the air around two glass manufacturing facilities in Portland. Further study indicated these businesses were likely the source of metals air emissions.
There are federal laws limiting these types of emissions. However, for glass manufacturing, the industry standards focus on emissions for large facilities, such as those that make beer bottles.
Benchmarks are Oregon’s protective “clean air” goals that DEQ developed to address toxic air pollutants. DEQ has identified levels of some toxic air pollutants that are still above Oregon’s air toxics benchmarks. This is a significant problem because toxic air pollutants are connected with serious health effects like cancer, respiratory problems and organ damage.
Based on sampling DEQ undertook in late 2015 and early 2016, DEQ concluded uncontrolled furnaces used in small art glass manufacturing are more likely than not to emit potentially unsafe levels of certain metals, including arsenic, cadmium, hexavalent chromium and nickel. The temporary rules DEQ proposed for EQC adoption were intended to immediately protect the public and the environment by ensuring the air emissions from small art glass facilities do not cause unsafe levels of metals in the air nearby.
