The Michigan Department of Environmental Quality is proposing changes to Mich. Admin. Code r. 336 regarding air pollution control. The changes would: (1) amend several definitions, including the limits on “significant rate of emissions” for several air contaminants; (2) rescind the section on limiting potential-to-emit by registration; and (3) amend the process and applicability for obtaining renewable operating permits. A public hearing will be held on December 7, 2015. Written comments will be accepted until December 18, 2015. See http://www.michigan.gov/documents/lara/MR20_111515_505823_7.pdf (pp. 124-235).
