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
categories.
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: McdonaldT@Michigan.gov.
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.
