On April 12, 2021 the Michigan Department of Environment, Great Lakes and Energy (EGLE) sent a letter supporting US Environmental Protection Agency (US EPA) continuing their assessment of the Gelman site for the National Priorities List (NPL). Until the EPA takes over, the Consent Judgment remains in effect.
The local governments have been looking at having the Gelman site listed on the National Priorities List (NPL), making it a 'Superfund' site, as a concurrent-path along with the court litigation activities. In 2016, Scio Township, Ann Arbor Township and the Sierra Club petitioned the US Environmental Protection Agency (EPA) to evaluate the site for the National Priorities List. EPA then conducted a Preliminary Assessment for the site.
A meeting with EPA Region V was held on July 15, 2016. This meeting summary was reviewed by EPA staff and their changes from the original version are shown.
