This memorandum documents the air quality analy ses and underlying planning assumptions performed by the Ohio Department of Transportation (ODOT), Division of Transportation System DevelopmentModeling and Forecasting Section and the Belomar Regi onal Council for the Annual PM2.5 on-road mobile source emission inventories for the Wheeling-Bridgepo rt WV/OH Metropolitan area State Implementation Plan (SIP) in coordination with the Ohio Environmental Prot ection Agency (OEPA) and West Virginia Department of Environmental Protection (WVDEP). The Belomar Region is comprised of the counties of Ohio and Marshall in the north panhandle of West Virginia and Belmont in east-central Ohio. On January 5, 2005, the USEPA designated all three counties as non-attainment for th e PM2.5 air quality standard. The designation became effective on April 5, 2005; 90 days after USEPA published action in the Federal Registry . Figure 1 displays the geographic extent of the Belomar region non-attainment area.

This report presents the latest population and land use data available that calibrated the modeling process used to calculate the vehicle emissions for the mobile emissions budgets as well as the input va lues for U.S. EPA’s most recent emissions software (MOVES) for this attainment demonstration. A series of conference calls held during the winter of 2010/2011 by the Interagency Consultancy Group estab lished two parameters. First, that th is re-designation effort will require

the use of MOVES software for all mobile source em ission analyses and second, the annual emission estimates will be based a single-season approach.

LAND USE DATA : Travel analysis zones (269 in the 3-county area) and ex ternal roadway “stations” (31) are the basic geographic units for estimating travel patterns. So cioeconomic data used to forecast th ese patterns shown in Table 3 include household population, school enrollment, vehicle registra tions, labor force participation, and employment by category and location. Sources for year 2000 data include the 2000 Census (primarily SF1 block data), state vehicle registration files, and QCEW/ES202 employment data. All data sources were geoc oded to the zone level. Future year data for each variable were projected th rough various methods. More de tailed explanation of base year and future year data generation for each of the a bove-mentioned categories of planning data follows. Figure 2 displays the zones boundaries in the region.

Table 3

BELOMAR REGION LAND USE DATA USED FOR TRAFFIC FORECASTING

For most future-year socio-economic data, Belomar staff uses county level projections as prepared by Woods and Poole. Allocations of county-level totals by zone are documented in the BOMTS report “BOMTS Traffic Zone

Data for 2025” with modifications since the date of the report, based on plans submitted for major land developments (such as Cabela’s, Center Wheeling, an d properties near the Ohio Valley Mall). Woods and Poole’s employment projections at the county level ar e used as control totals for developing TAZ level employment by service, retail and manufacturing. The Woods and Poole’s projection at county level isTransportation Air Quality Analysis And Tech nical Documentation Wheeling-Bridgeport, WV-OH For the U.S. EPA 1997 Annual PM2.5 National Ambient Air Quality Standard 8/11/11 7 disaggregated from a national level employment projection. The national projection is developed using an export base approach. Regional differences are considered be fore county level employment is disaggregated. In assigning employment to zones, it is assumed that new sites with developed infrastructure will have a larger share of future employment. Given the topography of the re gion, it is assumed generally that new development will mostly occur in one east-west travel corridor (I-70/ US40) and one north-south corridor (Ohio Route 7 and US250/WV Route 2 along the Ohio River). In Belmont County, however, additional development is expected along SR331 and in areas surrounding the urban core. Due to a scarcity of developable land in Ohio County, development will occur on sites that are generally flat a nd can be adequately serviced. In addition, over time, generally flat land in the valley will selectively go through planned land use changes to optimize economic development.

GEOGRAPHIC AREA COVERED BY TRAVEL MODEL AND TRAFFIC ZONE STRUCTURETransportation Air Quality Analysis And Tech nical Documentation Wheeling-Bridgeport, WV-OH For the U.S. EPA 1997 Annual PM2.5 National Ambient Air Quality Standard 8/11/11 8 TRAVEL MODELING : A travel demand model (TDM) is the traditional fore casting tool used to examine potential changes in future travel patterns. The road networks within th em include all planned federa l-aid projects as well as any regionally significant projects found in the TIP and LRTP expected to be open for traffic by the end of each respective analysis year. All projects identified in th e LRTP having an impact on travel time and/or vehicle carrying capacity regardless of funding source were included in the air quality analysis. Trip generation figures by zone, with some exceptions, are assumed to change lin early with time between 2000 and the Plan Horizon year

of 2035.

The Wheeling area travel demand model network covers a bout 1500 miles of streets and highways in the 3-county area including all collector and arterial streets, and has b een validated to observed traffic for year 2000. Land use data comes from the Census, ES202 employment reporting, and local vehicle registrations. A trip generation model was borrowed from another urban area and adjusted as needed for local land use data. The hourly distribution of trips by trip purpose and direction are constr ained to match the hourly distribution of traffic counts. Trip distribution also begins with a trip-length dist ribution by purpose borrowed from another urban area and adjusted to ensure modeled VMT matched HPMS estimates of VMT within 1% in the model base year of 2000. (Home-based work trips were separately constrained to a target average value based on the 2000 Census.)

The 3-county major street network used in the modeling was developed from the local planning agency’s digital street network (originating from the U.S. Geological Su rvey). The modeling software program utilizes hourly

saturation flow rates that are calculated based on road i nventory data, roadway type, and the 2000 version of the Highway Capacity Manual (HCM). Coded speeds by street segment are a function of road type and posted speed

limits and are based on the Ohio statewide travel ti me study conducted in 20 00 (available on the web at http://www.dot.state.oh.us/urban/data/statewid/report.doc ) using the “run time” version of speeds without intersection delays. The model software program interna lly estimates additional travel times for vehicles that stop for traffic control (stop signs and red lights) based on HCM methods and modeled traffic patterns. The traffic assignment RMS (root mean square) error meets FHWA /ODOT standards for all specified volume groups.

Overall modeled VMT for 2000 was less than 1% diff erent than HPMS estimated VMT. Freeways (federal functional class codes 1, 11, and 12) we re within 2% of estimated VMT.

The interagency consultation process, as previously discussed, established the following model years for Ohio and Marshall counties, WV and Belmont County, OH that re flected the most recent correspondence from the U.S.

Several custom programs created by ODOT staff were used to compute the total emissions. The process uses data on daily and directional traffic distributions as well as more up to date volume/delay functions from the 2000 Highway Capacity Manual (HCM). This process also uses re written code able to handle the newer model network formats and MOVES generated emission factors.

The first step in the process involves running postcms .exe to calculate hourly link volumes based on the percentage of the daily volume (travel demand model outpu t) determined by a link’s facility and area type. The analysis does not use the link speeds from the travel de mand model. Using a link’s volumeto- capacity ratio and link group code, a post-process to the model based on HCM methods estimates the link speeds. The second step (mmoves.exe) uses a combination of the MOVES emission factors and the hourly link volumes that are output of the postcms.exe program. The hourly volumes multiplied by the MOVES emission factor for the corresponding hour of day, speed bin, and road type; calculate emissions for every network link for each hour. The final link on

road vehicle emissions for the area is the sum of all indi vidual link-hour emissions. The third step, (vehcalm.exe), calculates vehicle-based emissions for each source type for each hour of the day. A combination of local and default data is the source for the vehicle source type. Th e final vehicle emissions for each county are the sum of all individual hourly emissions for all vehicle types. Sin ce the intrazonal trips are not loaded onto the network, the fourth step in the process requires a separate method to account for those trips that use lo cal roads to travel within a zone. The intracalm.exe program uses intrazonal trips to estimate VMT using the area in square miles and intrazonal trips of each zone. The computer program assumes that the zone is circular and uses the radius of the circle as the average trip length for these intrazonal trips. By combining MOVES generated emissions with estimated intrazonal VMT, the intrazonal emissions are then calculated. The emission rates are the same as those used to calculate link based emissions. The final step is to summarize link, vehicle, and intrazonal emissions for each county, pollutant, and analyzed year.

Dear Folks:

Below is the public notice for the Wheeling, WV 1997 PM 2.5 Redesignation and Maintenance Plan. The complete

document is available on the website listed in the notice. I have attached the transportation section for your

convenience. The narrative borrows very heavily from the Belomar/ODOT September 2011 Transportation Air Quality Analysis and Technical Documentation. For the reasons outlined in the excerpt, the DEP is proposing to make a finding

that regional highway emissions of PM 2.5 , NOx and SO 2 are insignificant contributors to the nonattainment problem for

the Wheeling area. The finding will become final if EPA concurs and approves this SIP revision. Therefore, no transportation conformity Motor Vehicle Emission Budgets (MVEB) should be necessary. Please contact me if you have

any problems opening the attachment or accessing our website.

Thank you.
Fred

### NOTICE OF PUBLIC COMMENT AND HEARING

The West Virginia Department of Environmental Protection (DEP) is offering an opportunity for public comment, and will hold a public hearing, on the Proposed Redesignation Request and Maintenance Plan for the West Virginia Portion of the Wheeling, WV-OH 1997 PM 2.5 

### Nonattainment Area . The document concerns two inter-related actions regard ing the West Virginia por tion of the nonattainment ar ea, comprising Marshall and Ohio Counties. First, DEP is request ing that the U.S. Environmental Prot ection Agency (EPA) redesignate the area to attainment pursuant to the pr ovisions of the Clean Air Act, sect ion 107. Second, DEP is asking that EPA concurrently approve, as a revision to the State Implementation Plan (SIP), the related maintenance plan which

demonstrates that the area will continue to meet the PM 2.5 

### air quality standards for at least ten more years. DEP is expressly soliciting comme nt on whether the proposed maintenance pl an adequately meets the requirements of the Clean Air Act, section 175A, as well as any relevant comments regarding the incorporation of the finalized maintenance plan into the West Virginia SIP. The comment period will b egin on January 27, 2012 and end on February 28, 2012.

The area was designated as nonattainment with the 1997 PM 2.5 

### annual National Ambient Air Quality Standard (NAAQS) in the January 5, 2005 Federal Register [70 FR 944], effective April 5, 2005. On November 20, 2009, in accordance with Section 179(c)(1) of the CAA, EPA determined that the Wheeling, WV-OH PM 2.5 

### nonattainment area had a ttained the 1997 annual PM 2.5 

### NAAQS by the applicable attainment date of April 5, 2010 [76 FR 75465]. DEP shows that the measured ai r quality improvement has been achieved through federally enforceable emission reduction measures. Furt her, DEP shows that with expected growth and federally enforceable controls, the area will continue attainment of the NAAQS for at least ten years.2 

### Written and oral comments will be accepted until the clos e of the public hearing and will be made part of the formal record. The public hearing shall be held be ginning at 6:00 p.m. on Tues day, February 28, 2012 at DEP headquarters: 601 57 th 

### Street, SE, Charleston, WV 25304. Written comme nts will also be accepted for inclusion in the formal record by mail, facsimile (304-926-0479), e-mail ( Tammy.L.Mowrer@wv.gov ) or other delivery to the Division of Air Quality if r eceived by the close of business on Fe bruary 28, 2012. Send written comments

to be included in the formal record to John A. Benedict , Director, Division of Air Qu ality at the address above. Please identify the document to which the comments apply, the commenter’s name, address and telephone

number.

Copies of the proposed SIP revision and documentation may be viewed on weekdays between 8:30 a.m. and 4:30 p.m. at the Division of Air Quality, 601 57 th 

### Street, SE, Charleston, WV 25304. Copies may alternatively be reviewed at the Bel-O-Mar Regional Council at 105 Bridge Street Plaza, Wh eeling, WV 26003, phone (304) 242-1800.
