Hampshire 2008Periodic Emissions Inventory for Ozone Precursors 1 . INTRODUCTION This document and attached spreadsheet tables serve as New Hampshire's State Implementation Plan (SIP) submittal of its 2008 Periodic Emissions Inventory (PEI) for ozone precursors. Calendar year 2008 emissions estimates for NewHampshire have also been submitted via EPA's newEmissions Inventory System(EIS) for inclusion in the 2008 National Emissions Inventory (NEI) . Together, these submissions fulfill NewHampshire's emissions reporting obligations as required in its SIP and under the Consolidated Emissions Reporting Rule (CERR) at 40 CFR Part 51 . The sections immediately following provide an overviewand summary of NewHampshire's 2008 PEI, including pollutants of concern, general methodologies, and geographic coverage. Subsequent sections describe in more detail the methodologies and assumptions used in the estimates for the various emissions categories. The emissions categories included in this submittal are as follows: " Point Sources (Section 2) are discrete facilities which generally report their emissions directly via theAir Emissions Inventory and Reporting programat the NewHampshire Department of Environmental Services (NHDES) . Point sources usually represent larger facilities. Area Sources (Section 3) comprise a wide range of anthropogenic activities that generate emissions. These activities are generally too widespread and numerous to be inventoried individually; therefore, estimates for these categories are made using available state-wide data such as population, employment, and fuel consumption. Also included in Section 3 are NonRoad Mobile Sources. Non-road mobile sources include a variety ofvehicles and equipment which do not operate on roadways, including construction vehicles, lawn and garden equipment, and recreational vehicles. For the purposes of New Hampshire's PEI, aircraft, locomotives, and commercial marine vessels are also included in the non-road mobile category. 

### On-Road Mobile Sources (Section 4) arevehicles that areprincipally intended to beoperated on roadways. This category includes cars,trucks, buses, and motorcycles. " Biogenic Emissions are naturally-occurring emissions due tovegetation and other nonanthropogenic sources. EPAand other parties will be calculating biogenic emissions to support ozone SIP-related activities such as photochemical air quality modeling. NHDES will accept these estimates. In theAir Emissions Reporting Requirements (AERR) Final Rule, EPA is proposing to remove the requirement that state, local, and tribal agencies report biogenic emissions. Therefore, biogenic emissions are not addressed further in this submittal . 

### 1.1 Pollutants ofConcern The 2008 PEI was prepared in support of NewHampshire's SIP for attaining and maintaining the 1997 national ambient air quality standard for ozone. Therefore, the focus of this documentation is the two principal precursors of ozone, volatile organic compounds (VOC) and oxides of nitrogen (NOx) . However, because New Hampshire made a submittal to the NEI, emissions estimates were also made for the other criteria pollutants, including carbon monoxide (CO), sulfur dioxide (S02), particulate matter with an equivalent diameter of 10 microns (PM10), and particulate matter with an equivalent diameter of 2.5 microns (PM2.5) . For some source categories, estimates were also made for ammonia (NH3) . 1 .2 Methodology The methodologies used in the preparation of the 2008 PEI were based on standard guidance and procedures. The resources that NewHampshire used included EPA's Clearinghouse for Inventories 8 Emissions Factors (CHIEF) and Emission Inventory Improvement Program (EIIP) . Stated briefly,emissions estimates are generally made by multiplying an emission factor times an activity or

throughput factor. Many of the emission factors used in the calculations were based on AP-42, Fifth Edition, Compilation of Air Pollutant Emission Factors, Volume l: Stationary Point and Area Sources. Activity and throughput data was obtained froma wide variety of sources, including the U.S. Census Bureau, the U.S. Department of Energy, and New Hampshire state agencies such as the NH Department of Transportation and the NH Office of Energy and Planning. The calculations that were used for each category are shown in the tables, which can be found in the Microsoft Excel spreadsheets that accompany this documentation. Each spreadsheet tab is designed to be selfdocumenting, listing the methodology, emission factors, activity, and other assumptions that were used in the calculations. Emissions were calculated and apportioned to the county level using a variety of data elements including population, employment, product sales, housing units, and heating-degree days. The method that was used to apportion each emissions category is provided on each corresponding spreadsheet tab of the Excel workbook that accompanies this text. Many of the data elements used for apportionment are not available at a resolution lower than county level ; however, New Hampshire's 8- hour non-attainment area (discussed in greater detail below) does not followcounty boundaries. Since population data for NewHampshire was available at the town level, this data element was used to apportion the emissions estimates for many categories to the irregularly shaped 8-hour non-attainment area. Detailed population data for New Hampshire has been provided in the accompanying spreadsheet and is discussed further below . Quality assurance was employed during inventory preparation to ensure an accurate and high-quality inventory. Quality assurance measures included "reality checks" against previous inventories and hand-calculation checks of spreadsheet calculations. In addition, inventory staff fromthe point and area source sectors worked closely together to ensure that no emissions were double counted. 1 .3 Geographic Coverage In 1997, EPA promulgated the 8-hour ozone standard and published its final 8-hour ozone attainment designations and classifications in 2004. The State of NewHampshire contains one classified 8-hour non-attainment area, the NewHampshire portion of the Boston-Manchester-Portsmouth (SE) NH Ozone Non-Attainment Area. This area is classified as moderate, and contains parts of Hillsborough, Merrimack, Strafford, and Rockinghamcounties. So in total, New Hampshire has parts of four counties classified as moderate non-attainment. Cities and towns that are in the 8-hr non-attainment area are: Amherst, Atkinson, Auburn, Bedford, Brentwood, Brookline, Candia, Chester, Danville, Derry, Dover, Durham, East Kingston, Epping, Exeter, Fremont, Goffstown, Greenland, Hampstead, Hampton, Hampton Falls, Hollis, Hooksett, Hudson, Kensington, Kingston, Litchfield, Londonderry, Manchester, Merrimack, Milford, Nashua, Newcastle, Newfields, Newington, Newmarket, Newton, North Hampton, Pelham, Plaistow, Portsmouth, Raymond, Rochester, Rollinsford, Rye, Salem, Sandown, Seabrook, Somersworth, South Hampton, Stratham, and Windham . As of this writing, NewHampshire is in the process of submitting a formal request to EPA to re-designate this area as being in attainment of the 1997 8-hour ozone standard. Cheshire, Belknap, Coos, Carroll, Grafton, and Sullivan counties are classified as unclassifiable/attainment for the ozone standard. The tables in the attached spreadsheets showemissions estimates for each county and for the entire state. Estimates are also shown for the 8-hour non-attainment area. In addition, estimates are shown for the former 1-hour ozone non-attainment areas (i .e. the former Seacoast, Southern, and Marginal non-attainment areas) . Estimates for the former 1-hour areas are shown only for continuity with previous inventories. Figure 1, which is provided as an attachment to this document, contains maps showing the former 1-hour non-attainment areas as well as the current moderate 8-hour ozone nonattainment area.

### 1 .4 Inventory Summary

A summary of NewHampshire's 2008 PEI is presented in the following tables. Estimates in pounds per summer day for VOCand NOx are shown for the 8-hour non-attainment area in Table 1-1 and for the entire state in Table 1-2. Emissions are broken down into the point, area, non-road, and on-road sectors. Tables 1-3 and 1-4 compare the 2008 estimates with New Hampshire's two most recent PEIs from2002 and 1999. Statewide 2008 emissions estimates decreased by approximately 28%and 10% respectively for VOCand NOx when compared with 2002.

### 2 . POINT SOURCES Each year, NHDES collects emissions information frompoint source facilities within the state, tracks construction and modification actions by these facilities, and monitors compliance and enforcementactivities. Data collection for the point source inventory encompasses several types of report collation

and evaluation depending on the applicable air program . Generally, reporting is made via three routes: First, in accordance with CHAPTER Env-A 700 of NewHampshire's air regulations, all permitted sources are required to submit annual emissions inventories for the purpose fee calculation. Fees are assessed on a dollar perton basis for each ton of pollutant emitted. 

### Second, in accordancewith CHAPTEREnv-A 900, NOxandVOCemission statements are required for sources having 10 tons per year actual emissions of NOx annually and 10 tons per year actual emissions of VOCannually. Finally, most permitted sources are required to performadditional reporting to demonstrate compliance with various standards (e.g., National Ambient Air Quality Standards, NewHampshire Ambient Air Limits) . Reports for point sources subject to more than one of these programs were collected, collated, crossreferenced and if discrepancies existed, the point sources were contacted in order to determine correct usages or emissions. Also, many of these sources have Continuous Emissions Monitoring Systems (CEMS) or have been stack tested. Both of these types of data have been incorporated into the inventory. Data for the point source emissions was collected by the most complete means possible: from point source air programreporting, NOx and VOCemissions statements, reporting required by permits, field engineers, field trip reports, material purchase orders, material safety data sheets (MSDS) and process rate information. It is important to note that these reports required all of the information necessary to calculate the emissions, and to categorize them by Source Classification Code (SCC) . Reported information includes the process rate, the speciation, the name of the solvent, the operating schedule, the permitted emission limitation, and any control equipment as applicable. They also include New Hampshire specific factors, if developed. A reasonableness check was performed on the information provided by the reports. An emissions number was never accepted by itself, rather the data used tocalculate that number was -reviewed and, if accepted, the emissions were then recalculated independent of the point source report. These emissions were cross-checked against the emissions reported in the 1990, 1996, 1999, 2002 and 2005 inventories, and in some cases, against SARATitle III information. Also, when entered into ISteps, the in house emissions database, the calculations were redone and any math errors were detected since the computer itself does the emissions calculations. All ofthe sources have been extensively quality assured by NHDES personnel when entering theminto the EIS for the EPA reporting requirement. Therefore, all of these sources have had the emissions calculated and verified at least twice and usually more. Most of the emissions entered into the EIS were done under method code 9, by which emissions are calculated by ISteps based on the throughput and emission factors entered. The ozone dailies were calculated by ISteps which takes the annual emissions and multiplies it by the seasonal throughput percentage then divides it by the number of days of operation during the ozone season. However, where CEMdata was available, the ozone dailies were calculated both by the using the throughputs, emission factors and seasonal percentages as well as taking the ozone season CEM data and dividing it by the number of days of operation. In all cases the ozone daily emissions were similar enough sothat they were entered with method code 9 as well . Point source emissions for the 8-hour non-attainment area and for the entire state are summarized in Section 1 in Tables 1-1 through 1-4. Point source emissions by facility for the 8-hour non-attainment area are shown in Tables 2-1 and 2-2 below . A more detailed summary of emissions by individual facility is provided in Appendix A, which has been submitted electronically with this documentation.Table 2-1 : Point Source VOCEmissions for the 8-Hour Non-Attainment Area

### 3 . AREAANDNON-ROADMOBILE SOURCES As described in Section 1, area sources represent those emissions categories that are too widespread and/or numerous to be inventoried individually. In general, the calculations used to estimate area source emissions involve a descriptor of activity or throughput multiplied by an emission factor. Examples of activity and throughput include population, employment, and fuel consumption. The types of area sources for which NHDES has made emissions estimates can be grouped into the following broad categories: " Gasoline Marketing 

### " Degreasing (Surface Cleaning) " SurfaceCoating " Graphic Arts 

### " Asphalt Paving

### " Pesticide Use

" Commercial and Consumer Solvent Use " Bakeries " Waste Management Practices " Underground StorageTank Remediation " Residential, Commercial, and Industrial Fuel Combustion " Accidental and Intentional Fires Further, NHDES made emissions estimates for the following types of non-road mobile sources:



### . Non-road vehicles as contained in EPA's NONROADemissions model Aircraft,Airport Ground ServiceEquipment, and Auxiliary PowerUnits Locomotives Commercial Marine Vessels The emissions estimates that were madefor these categories are described further in the sections that follow . However, the reader is referred to the individual tabs in the attached spreadsheet tables for detailed information on the activity, emission factors, and other assumptions that were used in the emissions calculations for each subcategory. Area and non-road emissions estimates for the 8-hour non-attainment area and for the entire state are shown in Section 1 in Tables 1-1 through 1-4. 

### Note to Reader: Tablenumbers fromthis pointforward refer tothe individual tabs in the Microsoft Excel workbook entitled "NH2008 PEI Section 3Tables.xls," which has been submitted electronically along with this documentation. Additional emissions summaries can be found in the attached spreadsheet in Spreadsheet Tables 3-1 through 3-16. These summaries include VOC and NOx as well as the other criteria pollutants.

### Population is an important variable that is used in the emissions calculations for many area source

categories. In many cases, it is also used to apportion emissions to the appropriate geographic regions. 2008 population data for NewHampshire was obtained fromthe NewHampshire Office of State Planning. Populations by town were used to assign population to the non-attainment areas. The population data used in the New Hampshire2008 PEI is shown in SpreadsheetTable3-17. 3.1 Gasoline Marketing 

### Gasoline marketing emissions estimates were made for the following subcategories and source classification codes (SCCs) : 2501060050: Gasoline Service Stations Stagel: Total 2501060201 : Gasoline Service Stations: Tank Breathing & Emptying 2505030120

: PetroleumProduct Transport, Truck, Gasoline The activity factor used in the emissions calculations for these SCCs was gasoline throughput. The number of gallons of gasoline sold by month for 2008 was obtained from the New Hampshire Department of Safety. These figures are shown in Spreadsheet Table 3-18. The emission factors used for these SCCs were based on EIIP Volume III, Chapter 11, Gasoline Marketing (Stage 1 and 11). For Stage I (delivery fromtruck to service station), it was assumed that 99%of the gasoline in New Hampshire is dispensed with Stage I controls. Emissions estimates for Stage II (vehicle refueling at the pump) have historically been calculated as an area source category using gasoline throughput and MOBILE6.2 emission factors. However, these emissions are nowcalculated using EPA's Motor Vehicle Emissions Simulator (MOVES) and are included in the on-road mobile portion ofthe inventory. For the Stage I estimates, MOBILE6.2 refueling factors were developed and used to reflect the use of reformulated gasoline in NewHampshire's southern four counties. MOBILE6.2 input and output files can be found in Appendix B, which has been submitted electronically along with this documentation. Total emissions estimates for the gasoline marketing category were as follows:

The activity factor used in the calculations was employment. Data on the number employees by county for the applicable North American Industry Classification System (NAICS) codes was obtained from the U.S. Census County Business Patterns data series. A 20% reduction was applied to the emission factor to account for VOC RACT per NewHampshire's 15% VOC Rate of Progress (ROP) plan for the 1-hour ozone standard. Total emissions estimates for the degreasing category were as follows:

### 3.3 Surface Coating Surface coating activities involve applying paints, varnishes, lacquers, and other materials to a wide variety of surfaces, including residential structures, roadways, vehicles, and manufactured products. Surfacecoating emissions estimateswere made forthefollowing subcategories and SCCs: 2401003000

: Surface Coating, Factory Finished Wood 2401065000

: Surface Coating, Electronic & Electrical Equipment 2401080000

: Marine Coatings For architectural surface coating, the activity factor used in the emissions calculations was gallons of paint, whichwas obtained from"2008 Quantity of Paint &Allied Products", which can be found in Table 2 of the U.S. Census form MA325F. The nationwide estimates of the amount of paints used were proportioned to NewHampshire using the ratio of NewHampshire population to U.S. population. Similarly, for traffic markings, the quantity of paint was obtained from the same reference. The estimated amount of traffic markings used in New Hampshire were obtained by using the ratio of New Hampshire highway spending to total U.S. highway spending (highway spending for maintenance & services) . These figures were obtained fromthe U.S. Department of Transportation. Employment data was used as the activity factor for the other surface coating categories. As described above for degreasing, this information was obtained fromthe County Business Patterns data series. Emission factors for all surface coating subcategories included adjustments to account for the regulations New

Hampshire adopted to meet its 15%ROPplan for the 1-hour ozone standard, as some of those rules contained lower applicability thresholds and thus required reductions at area sources. Many of the subcategories involve a variety of industrial activities and facilities. Therefore, where applicable, point source subtractions were made to ensure that emissions were not double counted. Emissions estimates for the surface coating category were as follows:

: Graphic Arts, Total, All Solvent TypesThe methodology used in the calculations was taken from EIIP, Chapter 7, Graphic Arts and used

population as an activity factor. Since printing and other activities that fall under this category can occur at fairly large facilities, point source emissions associated with graphic arts were subtracted to eliminate double counting. Emissions estimates associated with the Graphic Arts category were as follows:

### 3.5 Asphalt Paving Emissions estimatesforthe asphalt paving category were madeforthefollowing SCC : 2461022000

: EmulsifiedAsphalt The activity factor for the asphalt paving category is gallons of asphalt paved. During the 2002 PEI cycle, the number of gallons of asphalt paved was obtained fromthe NH Department of Transportation. Similar data for calendar year 2008 (or other recent year) were not readily available. Therefore, EPA's Economic Growth Analysis System (EGAS) Version 5.0 was used to growthe 2002 activity data to 2008. The emission factor for this category was developed during the 1999 PEI cycle and assumed that 37%of the asphalt is emulsifier and that 9.5%of the emulsifier is VOC. The calculations also assumed 75% evaporation and a density of 8.34 Ib/gallon. Emissions for this category were apportioned to the counties using the total number of lane miles. Emissions estimates for the asphalt paving category were as follows:

Data on the amount of pesticide applied was obtained fromthe NH Department of agriculture. The most recent readily available data was for calendar year 2003. It was felt that this activity would not necessarily followany particular economic trends, and therefore it was assumed that 2003 would be adequately representative of 2008 for this category. Emission factors and calculation methodologies came fromEIIP Volume III, Chapter 9, Pesticides - Agricultural and Nonagricultural . Emissions were apportioned to the individual counties using agricultural acreage, which was obtained fromthe 2007 Census ofAgriculture. Emissions estimates for pesticide application were as follows:

: Bio-Solids Composting 2680002000

: Mixed Waste CompostingEmissions estimates for wastewater treatment have been carried forward from historical inventories

starting in 1996. The original methodologies were taken from Section 3.5.1 of Procedures for the Preparation of Emissions Inventories for Carbon Monoxide and Precursors of Ozone, Volume l: General Guidance for Stationary Sources. The activity for this category, millions of gallons per day of wastewater treated, were grown from the historical data using EGAS to obtain estimates for more recent inventories, including the 2008PEI . Emissions for landfills were estimated with EPA's Landfill Gas Emissions Model (LandGEM) Version 3.02 using the latest available data on landfill capacity for landfills throughout the state. Two of the state's largest landfills, Four Hills Landfill in Nashua and Turkey Recycling & Environmental Enterprises in Rochester, are inventoried as point sources and are therefore not included in the area source estimates described here. Also included in the waste management category are bio-solids composting and mixed waste composting. These estimates were taken froman ammonia emissions inventory prepared for the MidAtlantic Regional Air Management Association (MARAMA) as documented in Technical Memorandum : MANE-VU 2002 Ammonia Emissions Inventory for Miscellaneous Sources, Final, dated March 31, 2004. Emissions estimates forthewaste management practices category were as follows:

: Industrial Residual Combustion The methodologies for the area source fuel combustion category came primarily fromEIIP Volume III and AP-42. The activity factor for the combustion source categories was the amount of each fuel type burned. This data was obtained from the U.S. Department of Energy, Energy Information Administration (EIA) . Data was available for NewHampshire for each fuel type for the residential, commercial, and industrial sectors. Point source fuel use was obtained fromthe NHDESAir Emissions Inventory and Reporting programand subtracted fromthe EIA statewide fuel consumption figures. The remaining fuel consumption figures were assumed to apply to the area source category. In the case of industrial wood, the net remaining fuel use after subtraction was zero, implying that all industrial wood combustion occurs at permitted point sources. For the residential sector, the activity data was apportioned to the counties by the number of houses that use each fuel type and by heating degree days. For the commercial sector, the data was apportioned by heating degree days and employment, and for the industrial sector, the data was apportioned by employment. Housing data by fuel type was obtained from the U.S. Census, and heating degree day data was obtained fromthe National Climactic Data Center. Detailed information on the fuel consumption and apportionment data that was used in the area source fuel combustion estimates can be found in Appendix C, which is enclosed electronically with this submittal . Detailed emissions summaries and calculations for each area source fuel combustion category can be found in the attached spreadsheet in Spreadsheet Tables 3-47 through 3-59 . As mentioned earlier, the activity data described above was multiplied by emission factors obtained primarily fromEIIP and AP42. The exception was the residential wood combustion category - these estimates were derived using EPA's Residential Wood Combustion Tool, Version 3 MV . Emissions estimates for the area source fuel combustion category were as follows:

Data on the number of structure and vehicle fires in the U.S. came froma 2009 National Fire Protection Association Document entitled Fire Loss in the United States During 2008 . The number of fires that occurred in NewHampshire was estimated using the proportion of NewHampshire population to U.S. population. Data were further apportioned to the NewHampshire counties using population.Estimates for open burning of yard waste and municipal yard waste burning were taken froma report

prepared for the Mid-Atlantic/Northeast Visibility Union (MANE-VU) entitled Open Burning in Residential Areas, Emissions Inventory Development Report, January 31, 2004. Because the estimates in this report were for 2002, they were grown to 2008 using EGAS. Emissions estimates for accidental and intentional fires were as follows:

:Off-Highway Vehicles: Diesel As described in Section 1, the non-road emissions source category includes vehicles that generally do not travel on public roadways. This category includes a wide variety of vehicles and equipment including construction equipment; recreational vehicles such as snowmobiles and ATVs; and lawn and garden equipment such as lawnmowers, trimmers, and chain saws. For these types of equipment, emissions were estimated using the EPA's NONROAD2008a model for estimating emissions fromnonroad vehicles. The NONROAD model does not include aircraft, locomotives, or commercial marine vessels; these categories are discussed in the sections that follow . NONROAD model input files (*.OPT files) have been provided electronically in Appendix D . Emissions estimates for the non-road vehicles contained in the NONROAD model are shown below . It is important to note that these estimates do not include airport ground service equipment (GSE) . Estimates for airport GSE were made separately and are discussed further in Section 3.14.

: Airport Ground Service Equipment and Auxiliary PowerUnits shown in the attachedManchester-Boston Regional Airport is NewHampshire's largest airport. It serves northern New

England and serves as an alternative airport for the greater Boston area. Emissions estimates for all aircraft-related categories at Manchester Airport were estimated using the Federal Aviation Administration's (FAA) Emissions Dispersion Modeling System (EDMS) Version 5.1 .2. These estimates were made on behalf of the airport by KM Chng Environmental Inc. and documented in their report, Manchester-Boston RegionalAirport, 2008Airport Emissions Inventory, dated September 2010 . As mentioned above, these estimates addressed all aircraft-related activity at the airport, including commercial, commuter, general aviation, and military aircraft as well as ground support equipment (GSE) and auxiliary power units (APUs) . Emissions estimates for other airports in New Hampshire were made by NHDES using aircraft activity data taken from the FAA Air Traffic Activity Data System (ATADS) and the GCR & Associates 5010Web website. The unit of activity for aircraft emissions estimates is the landing-takeoff operation (LTO), which represents a complete takeoff and landing cycle. Specific phases of flight represented by the LTO include taxi out, takeoff, climb out, approach, landing, and taxi in. LTO activity data was multiplied by emission factors taken from references such as Procedures for Emission Inventory Preparation, Volume IV- Mobile Sources dated 1992 and Documentation forAircraft Component ofthe National Emissions Inventory, Methodology dated December 15, 2009 .

### 3.15 Railroad Locomotives Locomotive emissions estimateswere madeforthefollowing SCC : 2285002006

: Railroad Locomotives The activity factor for this category is the gallons of diesel fuel consumed by the railroads. This data was obtained by surveying the railroad companies that operate in New Hampshire. In many cases, the railroad companies were able to provide fuel use data for their locomotive operations in New Hampshire for 2008

. For existing railroad companies that did not respond to the survey, the fuel use data that was used for previous inventory cycles was grown to 2008 using EGAS. Emission factors were drawn from Technical Highlights, Emission Factors for Locomotives, dated April 2009. Locomotive emissions were apportioned to the individual counties using track miles. Emissions estimates for locomotives were as follows:

### 3.16 Commercial MarineVessels Commercial marinevessel (CMV) emissions estimateswere madeforthefollowing SCCs: 2280002200

: Commercial Marine Vessels, Underway Emissions 2280002100

: Commercial Marine Vessels, Port Emissions Emission factors used in the emissions estimates for CMVs were taken primarily fromChapter 7 of Final Regulatory Support Document: Control of Emissions from NewMarine Compression-Ignition Engines at orAbove. 30Liters per Cylinder, dated January 2003. Additional emission factor data was taken from the MANE-VU Marine Non-road Source Category Calculation Methodology Sheet. Additional information used in the calculations included assumptions about the amount of time that each vessel spends in the various phases of operation (i .e. cruise, reduced speed zone, maneuvering, and hotelling) and the engine load factor associated with each phase. The data used for these assumptions were based on Commercial Marine Activity for Deep Sea Ports in the United States, Final Report, dated September 1999 . All major commercial marine vessel activity in NewHampshire occurs in the port of Portsmouth in RockinghamCounty. Monthly pilot reports for the port of Portsmouth were obtained fromthe Pease Development Authority for 2008 . These reports provided the name of each vessel that made a call to port, the date of its arrival and departure, its dead weight tonnage, and the horsepower of its assist tugs. These reports provided the activity data necessary to make the emissions estimates using the emission factors and operational assumptions described above. In some cases, it was clear fromthe pilot reports that the visiting vessel made a shift from one dock to another during its stay in port. In these particular instances, only the emissions associated with maneuvering and the assist tugs were accounted for. Emissions for the other phases of operation were accounted for on the days when the vessel arrived and departed. For most cases, however, the vessel remained at one dock or terminal during its stay, allowing emissions to be calculated for a single, complete cycle of operation. Emissions estimates for CMVs are shown below . The port of Portsmouth, where all major CMV activity in NewHampshire occurs, lies entirelywithin the 8-hour ozone non-attainment area.

### 4 . ON-ROADMOBILE SOURCES As described in Section 1, on-road mobile sources represent vehicles that operate principally on roadways; this includes cars, trucks, buses, and motorcycles. Historically, the method used to calculate emissions from on-road mobile sources was to multiply vehicle activity times an emission factor. On-road vehicle activity is commonly expressed in units of vehicle miles traveled (VMT) . In the past, emission factors were derived from MOBILE6.2. For this 2008 inventory however, NHDES used the MOVES model (MOVES2010a) . Further, using VMT, vehicle population, and other input data, NHDES ran MOVES in inventory, mode to produce on-road mobile emissions estimates directly rather than use the historic activity times emission factor approach.NHDES obtained 2008 VMT from the NewHampshire Department of Transportation and fromthe

Metropolitan Planning Organizations (MPOs) that comprise the 8-hour ozone non-attainment area. VMT were provided by town, allowing it to be distributed to the applicable geographic regions, including the counties and the non-attainment area. The MPOs derived VMT using the traffic demand models set up for their specific planning areas. Together, the MPOs' planning areas comprise New Hampshire's 8-hour non-attainment area. Therefore, the VMT that was obtained fromthe MPOs and that was used to derive the on-road mobile source emissions estimates was specific to the 8-hour nonattainment area. Vehicle population data were obtained from the NewHampshire Department of Safety and fromthe MPOs. On-road mobile source emissions estimates are summarized in Section 1 in Tables 1-1 through 1-4. As mentioned in Section 3.1, these estimates include emissions fromStage II vehicle refueling activity. Detailed MOVES input files have been submitted electronically as part ofthe overall submittal package for the re-designation request for the 8-hour ozone non-attainment area.
