State legislation: Illinois bill aims to lift state’s remaining nuclear moratorium
A bill that would fully repeal the state’s entire moratorium on new nuclear projects survived a key deadline in the Illinois General Assembly last week.
To stay afloat in the spring legislative session, bills needed to be assigned to committee by March 21, and state Sen. Sue Rezin’s Senate Bill 1527 now sits with the Senate’s Energy and Public Utilities committee for review.
