Michigan regulators are expanding an investigation into air pollution produced by a medical device manufacturer.
The Grand Rapids Press reports that the Department of Environmental Quality this month announced plans to widen air-quality testing around the Viant Medical facility in Grand Rapids.
State data show the toxin could be present in an area where the Kent County Health Department is studying cancer cases. The DEQ says it’s too soon to determine if there’s a link.
The department issued several pollution violations to Viant after noting elevated emissions of ethylene oxide, a known carcinogen.
A Viant spokesman says the company has taken steps to reduce emissions and is cooperating with investigators. A public meeting on the issue will be held March 6.
