Adequacy Status of the Allegan, Berrien, and Muskegon Counties, Michigan Submitted Reasonable Further Progress Plan for Transportation Conformity Purposes
Agency
Environmental Protection Agency (EPA).
Action
Notification of adequacy.
Summary
In this document, the Environmental Protection Agency (EPA) is notifying the public that we have found that the volatile organic compounds (VOC) and nitrogen oxides (NO X ) motor vehicle emissions budgets (budgets) in the submitted 2015 Ozone moderate Reasonable Further Progress (RFP) plan for Allegan, Berrien, and Muskegon Counties are adequate for conformity purposes. As a result of our finding, these areas must use the budgets from the submitted RFP plan for future conformity determinations.
Dates
This finding is effective April 15, 2024.

Supplementary Information
This notice is simply an announcement of a finding that we have already made. EPA Region 5 sent a letter to the Michigan Department of Environment, Great Lakes, and Energy on January 17, 2024, stating that the VOC and NO X budgets for Allegan, Berrien, and Muskegon Counties submitted in the 2015 RFP plan for the 2023 milestone year are adequate. The finding is available at EPA's conformity website: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm.
The budgets are as follows:
2023 VOC and NO X RFP budgets for the Allegan, Berrien, and Muskegon Counties Ozone Areas [Listed in tons per day (tpd)]
| Area | NO X(tpd) | VOC (tpd) |
| Allegan County | 1.15 | 0.70 |
| Berrien County | 2.98 | 1.85 |
| Muskegon County | 1.73 | 1.74 |
Transportation conformity is required by Clean Air Act section 176(c). EPA's conformity rule requires that transportation plans, transportation improvement programs, and projects conform to air quality state implementation plans (SIPs) and establishes the criteria and procedures for determining whether or not they do. Conformity to a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the national ambient air quality standards.
The criteria by which we determine whether a SIP's motor vehicle emission budgets are adequate for conformity purposes are outlined in 40 CFR 93.118(e)(4). We've described our process for determining the adequacy of submitted SIP budgets in our July 1, 2004, preamble starting at 69 FR 40038 and we used the information in these resources in making our adequacy determination. Please note that an adequacy review is separate from EPA's completeness review and should not be used to prejudge EPA's ultimate approval action for the SIP. Even if we find a budget adequate, the SIP could later be disapproved.
The finding is available at EPA's conformity website: https://www.epa.gov/otaq/stateresources/transconf/adequacy.htm.
