The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is holding a public comment period
and a virtual public hearing, if requested, to allow the public the opportunity to comment on the proposed
conditional approval of an air permit.

Public comment period from August 3, 2022, until September 16, 2022, and a virtual hearing, if

requested, on September 8, 2022, for:

Company: General Motors LLC Orion Assembly (GM) located at 4555 Giddings Road, Lake Orion, Michigan
What GM wants to do: Application No. APP-2022-0089 is for a proposed installation and operation of a new
automotive assembly line to replace the existing assembly line at the same location.
Legal Requirements: The proposal is subject to the state and federal Nonattainment New Source
Review and Prevention of Significant Deterioration (PSD) rules and regulations for a major modification to
an existing major stationary source because of the requested increase in some air pollutants, including
volatile organic compounds, particulate matter greater than or equal to 10 microns in diameter, particulate
matter greater than or equal to 2.5 microns in diameter, and greenhouse gases.
Additionally, the installation of the new assembly line would require revisions to Renewable Operating
Permit (ROP) No. MI-ROP-B7227-2020 (SRN B7227). This public comment period meets the public
participation requirements for a future administrative amendment to the ROP.
The review of the application has preliminarily determined that the request would not violate any of air quality
rules nor the National Ambient Air Quality Standards.
