State Attorney General Lisa Madigan is threatening to sue the federal government over a massive Foxconn Technology Group manufacturing facility that’s being built just north of the state’s border in Wisconsin.

Madigan says she will file a lawsuit challenging a recent rule issued by the EPA reducing the number of areas in Wisconsin that need to meet more strict ozone regulations.

Madigan says the EPA is “putting a company’s profit ahead of our natural resources and the public’s health.”

Foxconn, a Taiwan-based company, plans to build flat-screen display panels at the factory and could employ up to 13,000 people.
