Under the consent order, the company is to end sterilization using ethylene oxide by Dec. 31, conduct monthly air sampling through February, and pay a penalty of $110,000 within 30 days to the State of Michigan.
EGLE has been investigating over the past year and issued Viant several violations for inadequate capture and control of ethylene oxide emissions at its facility at 520 Watson Street SW. Testing found ethylene oxide emissions higher than state and federal health protective levels. Ethylene oxide is a known carcinogen that has been linked, in some people, to specific types of cancers when exposed to high levels over a long period of time.
The violations led to an escalated enforcement action by EGLE against Viant and the subsequent Consent Order, which was signed Nov. 26.
The Consent Order and responses to comments on the order can be found at Michigan.gov/Viant, along with additional information about actions by EGLE, ethylene oxide, and Frequently Asked Questions.
