31. Ove rvie w
All emissions processing for the revised 2002 OTC regional and urban 12 km base case simula tions was performed with S MOKE2.1 compi led on a Red Hat 9.0 Linux operating s ys tem with the P ortland group fortran compi ler version 5.1. The em issions processing was performed on a month- by

- month and R PO-b y- RPO ba sis, i.e. SM OKE processing was performed for each month for each of the R POs ( MANE-VU , VISTAS, CENRAP, M RPO) individuall y as well as for Canada. For each mon th/RPO combina tion,

a s eparate S MO KE A SSI GNS file wa s created, and the length of the episode in each of these A SSIG NS files wa s set to the entire month. Also, as discus sed in Section 3, there was no difference between “ episode- average” temp eratures and “monthl y- average” te mpera tures for the M obile6 simul ations that used the option of te mpera ture averaging.

This document

is structured as follows: A listing of all e mission inventories is given in Section 2, organized b y RPO and source categor y

. Section 3 discusses the Mobile6 processing approach emplo y ed for the different R POs, w hile Section 4 describes the processing of biogenic em issions with BEIS3.12. Finall y, Sections 5 through7 describe the tempora l allocat ion, speciation, and spatial allocat ion of the emissions inventories, respective l y.

5• Note about area and nonroad source S MO KE proces sing for the CENRAP region: All area source inventories (both annual and month- s pecific) were processed in

one step through SM OKE. SM K_AVED AY_Y N was set to N, so seasonal profiles were used to apportion the annual inventories numbers b y month. This setting was also used for the nonroad processing performed in a separate step. This wa s necessar y since the month- specific files had zero in their ‘average- day ’ colu mn and the annual total colu mn reflects the “monthl y emissions as annual totals” as per header line. Therefore, seasonal profiles are used to apportion both the annual and month- s pecific files. As described below, we utilized the tempor al profiles and cross-reference files generated by CENRA P. However, we did not verif y that this approach indeed leads to the intended month l y alloca tion of

am mo nia and nonroad em issions.

2.5.4 Point S ources
There has long been difficult y in obtaining an up-to- date Canadian criteria

em issions inventory for point sources. This is due largel y to confidentia lit y rights afforded to Canadian facili ties. Thus far, the most recent inventory of Canadian point sources is rooted in the 1985 N AP AP data and is close to two decades old. Because there

are a number

of high emi tting industrial facilit ies in s outhern Canada it is of particular impor tanc e to have a reasonabl y accurate inventor y of these sources especiall y when mode ling air qualit y over the Northeast and Midwest United States. Toward this end, an effort wa s m ade to obtain more recent Canadian point source data and incorporate it into

an inventory database, which could then be used for the 2002 OTC air qualit y mod eling.
Perhaps the most

accurate and publicl y accessible source of Canadian pollutant data is now available from the National Pollutant Release Inventor y ( NPRI) database. This database contains 268 substances. Facilit ies that manuf acture, process or otherwise use one of

these s ubstances and that mee t reporting thresholds are required to report these

em issions to Environm ent Canada on an annual basis. The N PRI data are available at Environ ment Canada’s website and can be found at the link http://www.ec.gc.c a/pdb/npr i/npri_ho me _e.cf m . The page hosts an on-line search engine where one can locate emissions by pollutant or location. In addition, the entire database is availab le for download a s an M S Access or Excel file. The N PRI database contains

9numerous pages with a rather compreh ensive list of inform ation. Detailed inform ation is availab le about each facilit y, including location, activi t y and annual em issions. In addition, facilities having stacks with a height of 50 met ers or more are required to report stack parame ters.

Unfortunatel y, one of the li mit ations of the NPRI database for modeling purpo ses is that the data are onl y

availab le at the facilit y level. Emissions models require process level infor mat ion, so in order to u se this data, a few generaliza tions had to be made. Each facili t y has a Standard Industrial Classification ( SIC) code as sociated with it; however,

em issions models require Source Classification Codes (SCC’ s). SCC’s are of critica l impor tanc e as the emissions models use these codes for assignment of tempora l and speciation profiles. SIC codes describe the general activit y of a facilit y w hile SCC codes describe specific processes taking place at each facili t y. While no direct relationship exists between these two codes, a general albeit s ubjective association can be made.

For the purpo ses of creating a model- ready inventor y file it wa s necessar y to obtain the whole N PRI database. After merg ing all the necessary componen ts from the N PRI database required in the SM OKE inventor y file, the S IC code from each facilit y wa s
exa mined and assigned an SCC code. In most cases, onl y

a S CC3 level code was assigned with confidence. While this is admit tedl y a less than de sirable proces s, it does allow for the use of the most recent em issions from the N PRI database to be u sed in mode ling. F urther more, having some level of SCC associated with these emissions will ensure that the y will be as signed a te mporal and speciation profile b y the model, other than the default. O nce the mode l- read y inventor y file wa s developed, it was proces sed through S MO KE.

a comm on reference county (i.e. Mobile6 input file)

o Te mporal averaging for May – September emissions processing: no te mporal averaging wa s used, i.e. day

- specific te mpera tures were used to calcula te emission factors for each da y.
o Te mporal averaging for non-summ er- mon ths emissions processing: Te mporal averaging over the duration of the episode (i.e. the entire month, see introduct ion) was u sed, i.e. month l y average te mperatur es were used to calculate the e mission factors.

- 1 temper ature), s olar radiation (“R GRND”), surface pressure (“ PRES”), and precipitat ion (“R N” and “ RC”). A ‘seasonal switch’ file was generated b y the S MOKE utilit y metscan to deter mine w hether winter or summ er e mission factors should be u sed for an y given grid cell on any given day

. Winter emission factors are u sed from January 1 st

through the date of the last frost and again from the data of the first frost in fall through December 31 st . Sum mer

emission factors are u sed for the ti me period in between. This calcul ation is performed s eparatel y for each grid cell.

145.5 Canada

For Canada, the SM OKE2.1 default tempora l profiles and cross-reference files (amp tpro.m 3.us+can.tx t and amp tref.m 3.us+can.tx t) were utili zed.

6. Speciation

The same speciation profiles (gspro.cmaq. cb4p25.txt) and cross-references (gsref.cm aq.cb4p25.txt) were utilized for all regions and all source categori es. Different versions of these files were obtained ( SMO KE2.1 default, EPA-C AIR mode ling, VISTA S, CENRAP and MA NE-VU) and compar ed. After comp aring the creation dates and header lines of these files, it wa s deter mined that the EPA-CAIR and MA NE-VU files had the most

recent updates, and consequentl y the final speciation profile and crossreference files used for all regions and source categories was ba sed on the EPA-CAIR files with the addition of MA NE-VU s pecific updates.

7. Spatial Allocation

7.1 U.S.

The spatial surrogates for the 12 km doma in were extracted from the national grid 12 km U.S. gridding surrogates po sted at EPA’s web site at http://www.epa.gov/ ttn/ chief/ em ch /spatia l/newsurrogat e.htm l The gridding cro ss-references were also obtained from this website, but for the processing of MA

NE- V U area source emissions, MA NE- V U specific cross-reference entries posted on the M ARAM A ftp site were added.

7.2 Canada

The spatial surrogates for Canadian em issions for the 12 km dom ain were extracted

from the national grid 12 km Canadian gridding s urrogates posted at EPA’ s website at http://www.epa.gov/ ttn/ chief/ em ch /spatia l/newsurrogat e.htm l The gridding cro ss-references were also obtained from this website.
