State workers are directing Bullseye Glass to reduce emissions of selenium after elevated levels were detected near a daycare.

Data from a monitoring device near the Children's Creative Learning Center on Sept. 6 showed 887 nanograms of selenium per cubic meter of air.

Oregon's 24-hour screening level for selenium is 710 nanograms per cubic meter of air.

Health officials said the 24-hour screening level is the line where negative health effects could occur.

The Department of Environmental Quality and Oregon Health Authority sent a joint letter to Bullseye on Friday confirming the company's commitment to limit the use of selenium in its art glass manufacturing process to no more than 5 pounds per day and only use selenium in furnaces controlled by a baghouse.

Scientists at the agencies believe that doing so will prevent spikes above the current 24-hour screening level.

The agencies also are requiring Bullseye to look into why a newly installed baghouse, which was expected to control emissions from 11 or more furnaces, apparently wasn't effective in preventing the Sept. 6 selenium spike.

DEQ has deployed monitoring devices in the area around Bullseye Glass since March, after high levels of heavy metals were found in the air.
