Twin Metals also agrees with the Star Tribune Editorial Board’s call for “agencies to conduct a rigorous, technology-driven and independent analysis” of the proposal. The federal environmental-impact statement (EIS) process that has been in place since the passage of the National Environmental Policy Act in 1969 requires agencies to do exactly that. A similar state program has been in use since the Minnesota Environmental Policy Act was passed in 1973. These processes rely on rigorous review of detailed project engineering plans and site-specific, empirical environmental data. These are processes citizens can trust.
