The Department of Environment, Great Lakes and Energy will hold a public hearing to receive public  
comments on proposed changes to the Part 6. Emission Limitations and Prohibitions – Existing Sources  
of VOC Emissions rule set.  
The proposed rule set (2022-18 EQ) will amend the current Part 6 containing rules developed to fulfill the  
federal Clean Air Act (CAA) 42 U.S.C 7401 et seq., requirements referred to as “Reasonably Available  
Control Technologies” (RACT). They are necessary to address moderate nonattainment area provisions  
for National Ambient Air Quality Standards (NAAQS). For past standards, EGLE promulgated RACT  
rules for existing VOC sources in the nonattainment areas established under those standards. With the  
establishment of a new standard, the state must:  
1)Revise existing RACT rules to align with the most recent recommendations contained in the United  
States Environmental Protection Agency’s (USEPA) Control Technique Guidelines (CTGs) as required by  
the CAA Section 182(b)(2).  
2)Evaluate VOC sources in the NAAQS nonattainment areas based on the more recently recreated CTG  
3)Promulgate new rules setting or revising emission standards and operational requirements for certain  
types of existing emission sources applicable to CTGs, beyond those established as rules under the  
previous standards, for the nonattainment areas. These nonattainment areas consist of the following  
counties: Allegan (partial), Berrien, Livingston, Macomb, Monroe, Muskegon (partial), Oakland, St. Clair,  
Washtenaw, and Wayne.  
Additionally, the CAA requires Michigan to show reasonable further progress by reducing VOC emissions  
in the nonattainment areas by fifteen percent from the baseline year. To meet this requirement, beyond  
the reductions gained from implementing VOC RACT rules, EGLE has also revised and drafted  
additional rules that address volatile chemical products.  
If approved, the rules will be submitted to the USEPA as an amendment to the Michigan State  
Implementation Plan (SIP). The comment period and hearing will fulfill requirements contained in the  
state administrative rules and the CAA.  
By authority conferred on the director of the department of environment, Great Lakes, and energy by  
sections 5503 and 5512 of the natural resources and environmental protection act, 1994 PA 451, MCL  
324.5503 and 324.5512, and Executive Reorganization Order Nos. 1995-16, 2009-31, and 2011-1, MCL  
324.99903, 324.99919, and 324. 99921.  
The proposed rules will take effect immediately after filing with the Secretary of State. The proposed  
issue of the Michigan Register. Copies of these proposed rules may also be obtained by mail or  
electronic mail at the following email address:  
Comments on these proposed rules may be made at the hearing, by mail, or by electronic mail at the  
following addresses until 10/26/2022 at 05:00PM.
