I. Background
OnNovember 13, 2009 (74 FR 58688), the Environmental Protection Agency (EPA) published air quality area designations for the 2006 PM2

.sNAAQS. Inthat rulemaking action, EPA designated the Harrisburg-Carlisle-Lebanon-York Area (Harrisburg-York Area) as nonattainment for the 2006 daily PM2

.s standard. The Harrisburg-York Area includes Dauphin, Lebanon, Cumberland, and York Counties in the Commonwealth ofPennsylvania. It is importantto note that York County was designated as a single-county nonattainment area for purposes ofthe 1997 annual PM2.s NAAQS, but was <;:ombined with Cumberiand, Dauphin, and Lebanon Counties to form the multi-county Harrisburg-YorkArea for purposes ofthe 2006 daily PM2.sNAAQS. On March 29, 2012 (77 FR 18922), EPA determined that the Harrisburg-York Areahad attained the 2006 daily PM2.sNAAQS based onquality-assured, quality-controlled, and certified ambient air monitoring datathat show the Area has monitored attainment based on 2008 through 2010 data.
II. Transportation Conformity Requirements Transportation conformity is required under section 176(c) ofthe Clean Air Act (CAA) to ensure that federally supported highway, transit projects, 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 "conform to" the goals ofSIP. This means that such actions will not cause or contribute to violations ofa NAAQS; worsenthe severity of
an existing violation; or delay timely attainment ofany NAAQS or any interim milestone. Actions involving Federal Highway Administration (FHWA) or Federal Transit Administration (FTA) funding or approval are subject to the Transportation Conformity Rule (40 CFRpart 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 FTA to demonstrate that their metropolitan transportation plans 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. Transportation agencies in Pennsylvania are responsible for making timely transportation conformity determinations. The responsible agencies in the Harrisburg-York Area, designated as the MPO under federal transportation planning requirements, are: 1) for Cumberland and Dauphin Counties: the Tri-County Regional Planning Commission; 2) for Lebanon County: the Lebanon County MPO; and 3) for York County: the York AreaMPO. Separate conformity budgets are being established for each MPO. The transportation conformity regulations (40 CFR §93.124(d)) allow a SIP to establishMVEBs for each MPO ifa nonattainment area includes
more than one MPO. ThePennsylvaniaDepartment ofTransportation has requested separate budgets to allow the planning organizations to move their transportation conformity determinations through the approval processes separately.
For MVEBs to be approvable, they must meet, at a minimum, EPA's adequacy criteria found at 40 CFR 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 subject to a State public hearing; (2) consultation among Federal, State, and local agencies occurred; full implementation plan documentation was provided to 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 on point 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 Motor Vehicle Emission Simulator (MOVES2010) Pennsylvania Department ofEnvironmental Protection (PADEP) utilized MOVES201 Oa to produce MVEBs for years 2017 and 2025. To utilize the MOVES2010a model, several different models were used to provide the necessary inputs into MOVES2010a. One ofthe models, PPSUITE, was utilized to provide inputs as well as to post-process the output files from

2MOVES2010a.
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 MOVES2010a viathe 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 MOVES201Oa. At that 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 methodologyutilized by PADEP and all modeling related information to produce the MVEBs for years 2017 and 2025. EPA found that all necessary and required modeling procedures were followed in the production ofthe 2017 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 withthe procedures listed inthe January 2008 Conformity Regulations contained in 40 CFRpart 93, 118(t) "Adequacy review process for implementation plan 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 Harrisburg-Carlisle-Lebanon-York, PA 2006 PMz

· budgets inthe Commonwealth ofPennsylvania's SIP will be addressed inthe final rulemaking notice.
Shown in Tables 1, 2, and 3 are the budgets from the Harrisburg-Carlisle-Lebanon-York, PA Maintenance Plan for milestone year 2017 and the out-year 2025 for PMz.s and NOx. The MVEBs will be applied to all future transportation conformity determinations and analyses for the 2006 daily PMz

In this TSD, EPA is evaluating the MVEBs associated withthe Harrisburg-Carlisle-Lebanonyork, 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 4, below.
