State environmental regulators say they'll reassess if Electro-Plating Services qualifies for Superfund status.
The company is the source of the contaminated green liquid that spilled onto a roadway in Madison Heights in December.
The U.S. EPA did what's called a "critical removal" of hazardous materials from Electroplating Services in 2017: hauling away anything that seemed like an imminent threat to public health.
But after that, a state assessment concluded there was no direct impact on public health from what was left on site, no threat to drinking water, and only limited migration of toxic substances off site.
So the site didn't qualify for Superfund status at the time.
Superfund status makes cleanups a priority and brings with it federal funds. The state's reassessment will see if that has changed in the wake of the spill.
