What's happening in Minnesota?
State lawmakers are debating whether Minnesota should place tougher regulations on frac sand mining. It's a growing industry that provides a key ingredient -- silica sand -- to oil and gas drillers for a process known as hydraulic fracturing, or fracking.
The debate at the Capitol pits those seeking the jobs and money that would come with new silica sand mines against the people who would live near those operations.
Meanwhile, in Wisconsin:
The state Senate has approved a Republican bill that would dramatically overhaul Wisconsin's mining regulations.
The measure is designed to ease the regulatory path for Gogebic Taconite's plans for a huge iron mine in the Penokee Hills just south of Lake Superior.
It will be interesting to see which approach yields better results.
