Bullseye Glass

Bullseye Glass Company manufactures colored art glass in southeast Portland.

DEQ issued a Bullseye’s Title V air quality permit on April 14, 2020. The permit is good for five years. Bullseye is required to provide reports to DEQ every six months. Those reports as well as copies of the permit, emissions detail sheet and review report are available on the Air Quality Permit Database

Timeline of events regarding DEQ's regulation of Bullseye Glass

March 2022: Bullseye has submitted all reports DEQ required in May 2021 (see drop down below). DEQ anticipates doing a full compliance inspection in 2022. ​​

May 2021: DEQ approves Bullseye's analysis of its potential to emit, completing the Notice of Compliance Status required as follow up to the 2017 source test. This approval comes with several additional requirements to ensure ongoing compliance:
  1. Daily monitoring and recordkeeping of the amount of regulated metals used and amount of glass produced, and calculate regulated metal usage per ton of glass on a weekly basis.
  2. Ensure that regulated metal usage does not exceed 157.5 lbs. of metals per ton of glass to ensure emission rates remain in compliance. Bullseye must report any exceedances to DEQ within 10 business days.
  3. Bullseye will provide data to DEQ every month. If there are no exceedances through the end of 2021, reporting will become semi-annual and be submitted with Title V permit reports.
When the Title V permit is up for renewal, DEQ will include these requirements. These requirements follow a warning letter DEQ issued after Bullseye failed to submit a complete Notice of Compliance Status following the 2017 source test.

This data does not suggest that there was ever a threat to the health of the surrounding community since DEQ required Bullseye to install the baghouse, but following through on the Notice is an important step in ensuring ongoing compliance.

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.

November 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.

​October 2015 - February 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.​​
