### Background
On January 5, 2005 (70 FR 944, 1014), the Environmental Protection Agency (EPA) published air quality area designations for the 1997 PM2.s NAAQS. Inthatrulemaking action, EPA designated York County, PA (the Area), which consists ofYork County, as nonattainment for the 1997 annual PMz

.s standard. On September 25,2009 (74 FR48863), EPA determinedthat the Areahad attained the 1997 PMz

.sNAAQS based on quality-assured, quality:controlled and certified ambient air monitoring data that showthe Area has monitored attainment based on 2006 through 2008 data.


### II. Transportation Conformity Requirements Transportation conformity is required under section 176(c) ofthe Clean Air Act (CAA) to ensure that federally supportedhighway, transitprojects, and other activities are consistent with (conform to) the purpose ofthe State Implementation Plan (SIP). The CAArequires federal actions in nonattainment and maintenance areas to "conformto" the goals ofSIP. This means that such actions will not cause or contribute to violations ofa NAAQS; worsen the severity ofan existing violation; or delay timely attainment ofany NAAQS or any interim milestone. Actions involving Federal Highway Administration (FHWA) or Federal Transit Administration (PTA) funding or approval are subject to the Transportation Conformity Rule (40 CPRpart 93, subpart A). Under this rule, metropolitan planning organizations (MPOs) in nonattainment and maintenance areas coordinate with state air quality and transportation agencies, EPA, FHW A, and FT A to demonstrate that their metropolitantransportationplans and transportation improvement plans (TIPs) conform to applicable SIPs. This is typically determined by showing that estimated emissions from existing and planned highway and transit systems are less than or equal to the MVEBs contained in a SIP.
For MVEBs to be approvable, they must meet, at a minimum, EPA's adequacy criteria found at 40 CPR 93.118(e)(4). EPA's adequacy criteria are:· (1) the submitted control strategy implementation plan was endorsed by the Governor or designee and was subjectto a State public hearing; (2) consultation among Federal, State, and local agencies occurred; full implementation plan documentation was providedto EPA; and EPA's stated concerns, ifany, were addressed before the control strategy implementation plan was submitted; (3) the MVEBs are clearly identified and precisely quantified; (4) the MVEBs, when considered together with all other emissions sources, are consistent with applicable requirements for maintenance; (5) the MVEBs are consistent with and clearly related to the emissions inventory and the control measures in the submitted control strategy implementation plan; and (6) revisions to previously submitted maintenance plans explain and document any changes to previously submitted budgets and control measures; impacts onpoint and area source emissions; any changes to established safety margins; and reasons for the changes (including the basis for any changes related to emission factors or estimates ofvehicle miles traveled).


### III. Review ofthe Submitted Modeling Utilizing the MotorVehicle Emission Simulator (MOVES2010) PennsylvaniaDepartment ofEnvironmental Protection (PADEP) utilized MOVES2010ato produce MVEBs for years 2017 and 2025. To utilize the MOVES2010amodel, several different models were used to provide the necessary inputs into MOVES2010a. One ofthe models, PPSUITE, was utilizedto provide inputs as well as to post-process the output files from MOVES2010a.
The appropriate traffic related inputs which were processed by PPSUITE were input into MOVES2010a. Additional traffic related inputs as well as non-traffic related inputs were provided as well. The data was input into MOVES2010aviathe county data manager. The county data manageris a function ofthe MOVES2010amodel which allows county specific data inputs to be converted into a usable form by MOVES2010a. Atthat point a Run Specification (RunSpec), which is a function ofMOVES2010athat allows the user to input necessary parameters into the model, was created and run in batch mode. The outputs were provided as an inventory because vehicle miles traveled (VMT) and vehicle population were provided to MOVES2010a.
EPA reviewed the modeling methodology utilized byPADEP and all modeling related

2informationto produce the MVEBs for years 2017 and 2025. EPA found that all necessary and required modeling procedures were followed in the production ofthe 20 17 and 2025 MVEBs which were produced using MOVES2010a.


### IV. Administrative Requirements for Making Adequacy Findings
EPA followed the process for determining the adequacy ofthe submitted SIP MVEBs in accordance with the procedures listed in the January 2008 Conformity Regulations contained in 40 CFRpart 93, 118(f) "Adequacy review process for implementationplan submissions." EPA will be issuing a notice ofproposed rulemaking (NPR) for a 30-day public commentperiod soliciting public comment for the approvability ofthe Commonwealth ofPennsylvania's SIP submission. The NPR also proposes approval ofthe MVEBs for milestone year 2017 and the out-year 2025 for the York County, PA 1997 PM2.s Nonattainment Area for PM2.s and nitrogen oxides (NOx).
Shown in Table 1 are the budgets from the York County, PA Maintenance Plan. The MVEBs in Table 1for milestone year 2017 and the out-year 2025 for PM2.s and NOx will be applied to all future transportation conformity determinations and analyses for the 1997 annual PM2.s NAAQS

.

### V. Evaluation ofthe Adequacy ofthe MVEBs in the YorkCounty, PAMaintenancePlan for the 1997 PM2.s NAAQS
In this TSD, EPA is evaluating the MVEBs associated with the York County, PA Maintenance Plan for conformity purposes. EPA is using the evaluation criteria detailed in the Transportation Conformity Rule, 40 CFRpart 93.102(b)(2)(v), 93.102(b)(2)(v), 93.102(b)(3), and part 93, 93 .118(e)4 through 93 .118(e)5. The evaluation is presented in Table 2, below.
