The Environmental Protection Agency (EPA) is approving a revision to the Minnesota State Implementation Plan (SIP) which updates Minnesota's air program rules. The Minnesota Pollution Control Agency (MPCA) submitted the request to EPA on November 14, 2018. The revision to Minnesota's air quality rules reflects changes that have been made to the State's air program rules since August 10, 2011, and updates on actions deferred from previous SIP submittals. EPA is approving the majority of MPCA's submittal, which will result in consistent requirements of rules at both the State and Federal level. EPA proposed to approve this action on February 5, 2020 and received no adverse comments.
