Approval and Promulgation of Air Quality Implementation Plans; States of Michigan and Minnesota; Regional Haze

摘要

In this notice of final rulemaking, EPA is disapproving in part the Michigan and Minnesota regional haze State Implementation Plans (SIPs) for failure to mandate best available retrofit technology (BART) for taconite facilities within these states. This final rule supplements a February 6, 2013, action that established Federal emission limits representing BART for these facilities.
