I. Background

OnJanuary 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 the Harrisburg-Lebanon-Carlisle Area (Harrisburg Area) as nonattainment for the 1997 annual PM2.s standard. The Harrisburg Area includes Dauphin, Lebanon and Cumberland Counties in the Commonwealth ofPennsylvania. OnAugust 25,2008 (73 FR49949), EPA determined thatthe Harrisburg Areahad attained the 1997 PM2.sNAAQS based onqualityassured, quality-controlled and certified ambient air monitoring datathat showthe Areahas monitored attainment based on2004 through 2006 data.

II. Transportation Conformity Requirements
Transportation conformity is required unqer section 176(c) ofthe Clean Air Act (CAA) to ensure that federally supported highway, transit projects, and other activities are consistent with (conformto) the purpose ofthe State Implementation Plan (SIP). The CAArequires federal actions in nonattainment and m'l:intenance areas to "conformto" the goals ofSIP. This meansthat such actions will not cause or contribute to violations ofaNAAQS; 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, metropolitanplanning organizations (MPOs) in nonattainment and maintenance areas coordinate with state air quality and transportation agencies, EPA, FHW A, and FT A to demonstrate that theirmetropolitan 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 agency for Cumberland and Dauphin Counties in the Harrisburg Area is the Tri-County Regional Planning Commission, the designated MPO under federal transportation planning requirements. The responsible agency for Lebanon County is the Lebanon County MPO. 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. The Pennsylvania Department 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 implementationplan 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 provided to EPA; and EPA's stated concerns, ifany, were addressed before the control strategy implementationplanwas submitted; (3) the MVEBs are clearly identified and precisely quantified; (4) the MVEBs, when consideredtogether 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 implementationplan; 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)
PennsylvaniaDepartment ofEnvironmental Protection (PADEP) utilized MOVES201 Oa to 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 utilized to provide inputs as well as to post-process the output files from MOVES2010a.

2The 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 datamanager. The county data manageris a function ofthe MOVES2010amodel which allows county specific data inputs to be converted into a usable form by MOVES2010a. At thatpoint a Run Specification (RunSpec), which is a function ofMOVES201 Oa that 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 informationto produce the MVEBs for years 2017 and 2025. EPA found that all necessary and required modeling procedures were followed inthe production ofthe 2017 and 2025 MVEBs which were produced using MOVES2010a.



### IV. Administrative Requirements for MakingAdequacy Findings

EPA followed the process for determining the adequacy ofthe submitted SIP MVEBs in accordance with the procedures listed inthe January 2008 Conformity Regulations contained in 40 CFRpart 93, 118(t) "Adequacy reviewprocess for implementation plan submissions." EPA will be issuing a notice

.ofproposed rulemaking (NPR) for a 30-daypublic 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-Lebanon-Carlisle, PA 1997 PM2.sNonattainment Area for PM2

.sand nitrogen oxides (NOx) for transportation conformity purposes. The public will have the opportunity to commenton the adequacy/approvability ofthe budgets inthe SIP revision. Following EPA's public commentperiod, responses to any comments received on the proposed mobile budgets inthe Commonwealth ofPennsylvania's SIP will be addressed in the final rulemaking notice.

Shown in Tables 1 and 2 are the budgets from the Harrisburg-Lebanon-Carlisle, PA Maintenance Plan for milestone year 2017 and the out-year 2025 for PM2.s and NOx. The MVEBs will be applied to all future transportation conformity determinations and analyses for the 1997 annual PM2

.sNAAQS.
