ST. PAUL — Ford Motor Co. and the Minnesota Pollution Control Agency say contamination shouldn’t get in the way of redeveloping the land in St. Paul where the company’s Twin Cities Assembly Plant once stood.

An environmental analysis released Tuesday night identified five hot spots that need attention, but they say plans can proceed for mixed-use development involving residences, light industry, office space and parkland.

Ford executive Rob Cory told an audience in St. Paul that the company expects to finish cleaning up the site and sell it to a developer by 2019.

MPCA hydrologist Amy Hadiaris says the 135-acre Ford site will be easier to clean up than some others because the bedrock is only 6 feet below the surface, making it easier to manage the contamination.
