Today is the last day for the public to weigh in on plans to expand a toxic waste facility in an east Detroit neighborhood.
US Ecology wants permission to expand its capacity to treat and store hazardous materials to 10 times what it handles now.
That includes byproducts from oil and gas fracking.
Concerns from local officials and residents who live near the facility prompted the Michigan Department of Environmental Quality to extend the public comment period twice.
Richard Conforti with MDEQ said so far, the state has received around 450 comments.
