EPA proposes to find that the contingency plan included in PADEPs March 10, 2020 submittal satisfies the pertinent requirements of CAA section 175Ad. EPA notes that while five of the potential contingency measures included in the Commonwealths second maintenance plan are nonregulatory, their inclusion among other measures is overall SIP-strengthening, and their inclusion does not alter EPAs proposal to find the LMP is fully approvable. EPA also finds that the submittal acknowledges Pennsylvanias continuing requirement to implement all pollution control measures that were contained in the SIP before redesignation of the Tioga County Area to attainment.

E. Transportation Conformity Transportation conformity is required by section 176c of the CAA.
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 CAA
176c1B. EPAs conformity rule at 40 CFR part 93 requires that transportation plans, programs and projects conform to SIPs and establish the criteria and procedures for determining whether or not they conform. The conformity rule generally requires a demonstration that emissions from the Regional Transportation Plan RTP and Transportation Improvement
Program TIP are consistent with the motor vehicle emissions budget MVEB
contained in the control strategy SIP
revision or maintenance plan 40 CFR
93.101, 93.118, and 93.124. An MVEB
is defined as that portion of the total allowable emissions defined in the submitted or approved control strategy implementation plan revision or maintenance plan for a certain date for the purpose of meeting reasonable further progress milestones or demonstrating attainment or maintenance of the NAAQS, for any criteria pollutant or its precursors, allocated to highway and transit vehicle use and emissions 40 CFR 93.101.
Under the conformity rule, LMP areas may demonstrate conformity without a
17 These regulatory measures were considered potential cost-effective and timely control strategies by the Ozone Transport Commission OTC as well as the Mid-Atlantic Regional Air Management Association and the Mid-Atlantic/Northeast Visibility Union. The OTC is a multi-state organization responsible for developing regional solutions to ground-level ozone pollution in the Northeast and Mid-Atlantic, including the development of model rules that member states may
adopt. OTC member states include: Connecticut, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Virginia.

18 Pennsylvanias existing controls on consumer products are under 25 Pa. Code Chapter 130, Subchapters B and C 38 Pa.B. 5598. This contingency measure includes the adoption of additional controls on consumer products such as VOC limits for adhesive removers.
19 Existing controls on portable fuel containers can be found under 40 CFR part 59, subpart F
Control of Evaporative Emissions From New and InUse Portable Fuel Containers.
