Don't Waste Michigan and Beyond Nuclear, represented by legal counsel Terry Lodge of Toledo, were two of the coalition groups that officially intervened, from 2010 to 2016, against Davis-Besse's 2017 to 2037 license extension. The other two coalition groups were the Ohio Green Party, and Citizens Environment Alliance of Southwestern Ontario.

For the past several years, FirstEnergy Nuclear has sought bailouts for its Ohio reactors, including both Davis-Besse and Perry. They have thus far been blocked, including by concerted grassroots environmental opposition. But this is their biggest push yet.
