Federal Register / Vol. 86, No. 125 / Friday, July 2, 2021 / Proposed Rules
EGLE has the legal authority to carry out the Michigan SIP under Act 451 and the Executive Reorganization Order 20111.
Michigans PSD regulations provide adequate resources to permit GHG
sources. EPA proposes that Michigan has met the infrastructure SIP
requirements of this portion of section 110a2E with respect to the 2015
ozone NAAQS.

2. State Board Requirements In this rulemaking, EPA is not proposing to approve or disapprove Michigans satisfaction of the state board requirements of section 110a2E for the 2015 ozone NAAQS.
Instead, EPA will evaluate Michigans compliance with these requirements in a separate rulemaking.
F. Section 110a2FStationary Source Monitoring System Section 110a2F contains several requirements, each of which are described below.
States must establish a system to monitor emissions from stationary sources and submit periodic emissions reports. Each plan shall also require the installation, maintenance, and replacement of equipment, and the implementation of other necessary steps, by owners or operators of stationary sources to monitor emissions from such sources. The state plan shall also require periodic reports on the nature and amounts of emissions and emissions-related data from such sources, and correlation of such reports by each state agency with any emission limitations or standards established pursuant to this chapter. Lastly, the reports shall be available at reasonable times for public inspection.
EGLE implements a stationary source monitoring program under the authority of MCL 324.5512 and MCL 324.5503 of Act 451. Additional emissions testing, sampling, and reporting requirements are found in Michigan Administrative Code Rules 336.201 through 336.202
and Rules 336.2011 through 336.2199.
Emissions data is submitted to EPA
through the National Emissions Inventory system and is available to the public online and upon request. EPA
proposes that Michigan has satisfied the infrastructure SIP requirements of section 110a2F with respect to the 2015 ozone NAAQS.
G. Section 110a2GEmergency Episodes This section requires states to have the authority to revise their SIPs in response to changes in the NAAQS, availability of improved methods for attaining the NAAQS, or to an EPA

finding that the SIP is substantially inadequate.
EGLE has the authority to require immediate discontinuation of air contamination discharges that constitute an imminent and substantial endangerment to public health, safety, welfare, or the environment under MCL
324.5518 of Act 451. MCL 324.5530
provides for civil action by the Michigan Attorney General for a violation as just described. EPA
proposes that Michigan has met the applicable infrastructure SIP
requirements of section 110a2G
related to authority to implement measures to restrain sources from causing or contributing to emissions which present an imminent and substantial endangerment to public health or welfare, or the environment with respect to the 2015 ozone NAAQS.
H. Section 110a2HFuture SIP
Revisions This section requires states to have the authority to revise their SIPs in response to changes in the NAAQS, availability of improved methods for attaining the NAAQS, or to an EPA
finding that the SIP is substantially inadequate.
EGLE continues to update and implement needed revisions to Michigans SIP as necessary to meet ambient air quality standards. Authority for EGLE to adopt emissions standards and compliance schedules is found at MCL 324.5512 and MCL 324.5503 of Act 451. EPA proposes that Michigan has met the infrastructure SIP requirements of section 110a2H with respect to the 2015 ozone NAAQS.
I. Section 110a2INonattainment Planning Requirements of Part D
The CAA requires that each plan or plan revision for an area designated as a nonattainment area meet the applicable requirements of part D of the CAA. Part D relates to nonattainment areas.
EPA has determined that section 110a2I is not applicable to the infrastructure SIP process. Instead, EPA
takes action on part D attainment plans through separate processes.
J. Section 110a2JConsultation With Government Officials; Public Notification; PSD; Visibility Protection The evaluation of the submissions from Michigan with respect to the requirements of section 110a2J is described below.

1. Consultation With Government Officials States must provide a process for consultation with local governments and Federal Land Managers FLMs carrying out NAAQS implementation requirements.
Michigan actively participates in the regional planning efforts that include business, community groups, state rule developers, representatives from the FLMs, and other affected stakeholders.
Michigan Administrative Code Rule 336.2816 requires that FLMs are provided with notification of permit applications that may impact class I
areas. Additionally, Michigan is an active member of the Lake Michigan Air Directors Consortium, which consists of collaboration with the States of Illinois, Wisconsin, Indiana, Minnesota, and Ohio. EPA proposes that Michigan has met the infrastructure SIP requirements of this portion of section 110a2J
with respect to the 2015 ozone NAAQS.
2. Public Notification Section 110a2J also requires states to notify the public if NAAQS are exceeded in an area and to enhance public awareness of measures that can be taken to prevent exceedances.
EGLE notifies the public if there are NAAQS exceedances and of any public health hazards associated with those exceedances through CleanAirAction!,8
AirNow,9, and EnviroFlash 10 as well as posting on its website.11 EGLE
published an annual air quality report comparing Michigan monitors to the NAAQS. EPA proposes that Michigan has met the infrastructure SIP
requirements of this portion of section 110a2J with respect to the 2015
ozone NAAQS.
3. PSD
States must meet applicable requirements of section 110a2C
related to PSD. EGLEs PSD program in the context of infrastructure SIPs has already been discussed in the paragraphs addressing section 110a2C and 110a2DiII, and EPA notes that the proposed actions for those sections are consistent with the proposed actions for this portion of section 110a2J. Therefore, EPA
proposes that Michigan has met all of the infrastructure SIP requirements for 8 https www.wmcac.org/todays-forecast.
