Approval and Promulgation of Air Quality Implementation Plans; Michigan; Part 3 Rules

The Environmental Protection Agency (EPA) is approving revisions to the Part 3 rules into the Michigan State Implementation Plan (SIP). On December 13, 2013, the Michigan Department of Environmental Quality (MDEQ) submitted to EPA for approval revisions to Part 3, Emission Limitations and Prohibitions--Particulate Matter (PM), for open burning and electro-static precipitators (ESPs). The revisions for open burning eliminate specific provisions to allow household waste burning, and add a provision to allow for burning of fruit and vegetable storage bins for pest or disease control with specific location limitations. The SIP request also removes rule 330 dealing with operation parameters for electrostatic precipitators because of redundancy, and rule 349 dealing with compliance dates for coke ovens because it is now obsolete. EPA is approving this SIP revision because it will not interfere with attainment or maintenance of the fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS).
