Adequacy Status of the New Jersey Portion of the New York-
Northern New Jersey-Long Island and Pennsylvania-Delaware Areas 
Submitted PM2.5 Limited Maintenance Plan, 2006 24 Hour PM2.5 
Maintenance Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of adequacy.

-----------------------------------------------------------------------

SUMMARY: In this notice, the Environmental Protection Agency (EPA) is 
notifying the public that we have found that the Limited Maintenance 
Plan for PM<INF>2.5</INF> for the New Jersey portion of the New York-

Wilmington, PA-NJ-DE, PM<INF>2.5</INF> maintenance areas, submitted by 
the New Jersey Department of Environmental Protection on July 6, 2023, 
is adequate for transportation conformity purposes. This revision to 
the State Implementation Plan is associated with the second ten-year 
PM<INF>2.5</INF> Limited Maintenance Plan.

DATES: This finding is effective on June 7, 2024.

SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we,'' 
``us,'' or ``our'' is used, we mean the EPA.
    Today's notice is simply an announcement of a finding that we have 
already made. On July 6, 2023, the New Jersey Department of 
Environmental Protection (NJDEP) submitted a State Implementation Plan 
(SIP) revision establishing the second ten-year maintenance plan as a 
limited maintenance plan (LMP) for the New Jersey portion of the New 
York-Northern New Jersey-Long Island, NY-NJ-CT (Northern New Jersey) 
and Philadelphia-Wilmington, PA-NJ-DE (Southern New Jersey) 2006 24-
hour fine particulate matter (PM<INF>2.5</INF>) maintenance areas. We 
announced availability of New Jersey's LMP on the EPA's transportation 
conformity website on August 16, 2023, (<a href="https://www.epa.gov/state-and-local-transportation/state-implementation-plans-sip-submissions-currently-under-epa#NY-NJ-CT-PM2.5">https://www.epa.gov/state-and-local-transportation/state-implementation-plans-sip-submissions-currently-under-epa#NY-NJ-CT-PM2.5</a>) and requested comments by September 
15, 2023. We received no comments in response to the adequacy review 
posting. EPA Region 2 sent a letter to the New Jersey Department of 
Environmental Protection on March 18, 2024, stating that the LMP for 
the Northern New Jersey and Southern New Jersey maintenance areas is 
adequate for transportation conformity purposes.
    In October 2022, EPA issued Guidance on the Limited Maintenance 
Plan Option for Moderate PM2.5 Nonattainment Areas and PM2.5 
Maintenance Areas (EPA-420-B-22-044). The transportation conformity 
regulations require that ``A limited maintenance plan would have to 
demonstrate that it would be unreasonable to expect that such an area

[[Page 45659]]

would experience enough motor vehicle emissions growth for a [national 
ambient air quality standards (NAAQS)] violation to occur.'' \1\ 
Additionally, the PM<INF>2.5</INF> LMP guidance suggests ``an LMP may 
be particularly appropriate for a second maintenance plan, as the area 
will have demonstrated attainment of the PM<INF>2.5</INF> NAAQS for at 
least 8 years.'' \2\
---------------------------------------------------------------------------

    \1\ See 40 CFR 93.109(e) and EPA's ``Guidance on the Limited 
Maintenance Plan Option for Moderate PM<INF>2.5</INF> Nonattainment 
Areas and PM<INF>2.5</INF> Maintenance Areas.''
    \2\ See EPA's ``Guidance on the Limited Maintenance Plan Option 
for Moderate PM<INF>2.5</INF> Nonattainment Areas and 
PM<INF>2.5</INF> Maintenance Areas.''
---------------------------------------------------------------------------

    To meet the transportation conformity regulation, i.e., demonstrate 
that it would be unreasonable to expect that the area would experience 
enough motor vehicle growth for a NAAQS violation to occur, an LMP 
submission for an area's second maintenance plan should again address 
the area's PM<INF>2.5</INF> air quality trends and its historical and 
projected vehicle miles traveled (VMT). Since the Northern New Jersey 
and Southern New Jersey areas have been attaining the PM<INF>2.5</INF> 
NAAQS for 10 years, with a low risk of future exceedances, we find the 
LMP adequate for transportation conformity purposes. Once an area has 
an approved or adequate LMP for a specific pollutant and NAAQS, the 
area no longer needs to satisfy the regional emissions analysis for CFR 
93.118 and CFR 93.119.\3\ A conformity determination that meets the 
requirements outlined in CFR 93.109(b)(Table 1), including the hot-spot 
requirements for projects in CO, PM<INF>10</INF>, and PM<INF>2.5</INF> 
areas, is still required for these maintenance areas with an approved 
or adequate LMP.\4\
---------------------------------------------------------------------------

    \3\ See 40 CFR 93.109(e) and EPA's ``Guidance on the Limited 
Maintenance Plan Option for Moderate PM<INF>2.5</INF> Nonattainment 
Areas and PM<INF>2.5</INF> Maintenance Areas.''

    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 State air 
quality 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 NAAQS.
    The criteria by which we determine whether a SIP's Limited 
Maintenance Plan is adequate can be found in 40 CFR 93.109(e). 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 limited maintenance plan adequate, the SIP 
could later be disapproved.
    Authority: 42 U.S.C. 7401-7671q.
