Colored Art Glass Manufacturer Emissions

Proposed Temporary Rule
Contact: Jill Inahara, 503-229-5001

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 last October, and in recent weeks, DEQ has concluded that uncontrolled furnaces used in such 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 that DEQ proposes for EQC adoption are intended to immediately protect the public health and the environment by ensuring the air emissions from small art glass facilities do not cause unsafe levels of metals in the air nearby.
