ST. PAUL (AP) — Ramsey County will buy and clean up a 427-acre tract of polluted land in Arden Hills that had been considered as the site for a new Minnesota Vikings stadium.

County commissioners voted 5-2 Tuesday to spend $30 million on a portion of the Twin Cities Army Ammunition Plant site. It's part of the state's largest Superfund site, but also one of the biggest pieces of undeveloped land in the Twin Cities.

The site is polluted with lead, depleted uranium, industrial solvents and other contaminants. County officials hope to redevelop the land and sell it to private owners. In 2011, county commissioners struck a deal with the Vikings to build a new stadium there but state lawmakers would not sign onto the plan.
