Bullseye Glass Company manufactures colored art glass in southeast Portland.

Timeline of events regarding DEQ's regulation of Bullseye Glass

On June 5, 2020, Bullseye submitted a Notice of Compliance Status regarding the 2017 source test. DEQ deemed it incomplete and, on Aug. 20, 2020, sent Bullseye a warning letter that lists the specific information DEQ needs to evaluate compliance.

DEQ should have been more timely regarding follow up documentation with the facility. However, Bullseye operates with a baghouse, the most effective emission control technology for this type of facility, which ensures protection of public health and the environment.

April 2020: DEQ issues Title V air quality permit, which includes emission limits, emissions controls, chromium usage limits, and monitoring and reporting requirements. DEQ will verify compliance with permit conditions by reviewing annual reports and conducting periodic inspections of the facility, at least every two years.

May 2017: DEQ receives Title V air quality permit application.

Nov. 2016: DEQ proposes and Oregon Environmental Quality Commission adopts permanent Colored Art Glass Manufacturing rules

June 2016: DEQ signs Mutual Agreement and Order with Bullseye that specifies additional requirement and controls for operation.

April 2016: DEQ proposes and Oregon Environmental Quality Commission adopts temporary Colored Art Glass Manufacturing rules that require additional emissions controls. DEQ determines Bullseye needs a Title V air quality permit rather than the Simpler Air Contaminant Discharge Permit it previously had.

March 2016: DEQ deploys additional air monitors to collect more data.

Oct. 2015 – Feb. 2016: DEQ deploys temporary air monitors that confirm what the moss data suggested—there were elevated levels of air toxics in these areas.

May 2015: Data from this initial moss study shows potentially elevated levels of air toxics in several Southeast Portland neighborhoods near art glass manufacturing facilities.

2013: DEQ and U.S. Forest Service begin partnering on a moss sampling study to determine if moss could be used as an indicator of air quality.
