                                SECTION 1
                              INTRODUCTION

    This report describes the work that GCA Technology Division performed in
updating the National Emission Data System (NEDS) for Utah for the EPA.
    The point source data was obtained from the files of the Air Quality
Section of the Utah State Division of Health.  Data for about 80 sources was
recorded on NEDS point source forms.  Sources with the potential to emit
over 25 tons/year of any of the five major pollutants, (particulates, sulfur
dioxide, nitrogen oxides, hydrocarbons, and carbon monoxide) were included.
    The Air Quality Section of the Utah State Division of Health completed
the NEDS area source forms during August 1973.  GCA evaluated the methods
used and thoroughly checked the area source forms.
    In order to present the geographical distribution of emissions in the
area of the highest emissions, a grid system for the Davis, Salt Lake, Utah,
and Weber County areas was developed by GCA.  The grid consisted of 312
squares ranging in size from 400 km2 to L57 km2.  Emissions from all sources
were calculated for each grid.

                                SECTION II

                     SUMMARY OF POINT AND AREA SOURCES


    The results of the emission inventory are summarized in tables 1 and 2.

Table 1 summarizes the data by Air Quality Control Region and source type.

Table 2 summarizes the data by county and source type.  Figure 1 is a map of

Utah, the Air Quality Control Regions, and the counties.  A general discus-

sion of the results for each of the five pollutants is presented in the fol-
lowing sections.

    A.  Particulates

        1.  Statewide, 36% of the calculated particulate emissions
            were from area sources.  Combustion of coal by industry
            was responsible for over half of the area source parti-
            culate emissions.  Point sources accounted for 64% of
            the particulate emissions.  About one-third of the point
            source emissions were from coal combustion.

        2.  The particulate emissions rates from the three AQCR's
            were quite different.  Only 3% of the total particulate
            emissions in Utah occurred in the Four Corners Interstate
            AQCR.  Particulate emissions in the small Wasatch Front
            Intrastate AQCR accounted for 67% of the particulate
            emissions in Utah.

    B.  Sulfur Dioxide

        1.  Area sources accounted for only 9% of the sulfur dioxide
            emissions in Utah.  Industrial combustion of distillate oil,
            residual oil and coal was the primary area source of sul-
            fur dioxide.  A copper smelting operation in the Wasatch
            Front AQCR was responsible for 65% of the sulfur dioxide
            emitted in Utah.  The remainder of the point source sulfur
            dioxide emissions was caused by fuel burning.

        2.  Sulfur dioxide emissions from the Wasatch Front AQCR were
            92% of the state total.  Point sources in the Wasatch Front
            AQCR accounted for 85% of the sulfur dioxide emitted in
            Utah.

    C.  Nitrogen Oxides

        1.  Area sources account for 77% of the nitrogen oxides emission
            in Utah.   On and off highway fuel use accounts for over half
            the nitrogen oxide emissions.  Point source emissions of
            nitrogen oxides are caused by fuel burning operations.  The

-------
        largest point sources are petroleum refining and metal-
        lurgical industries.

    2.  The Wasatch Front Interstate AQCR accounts for 68% of the
        nitrogen oxide emissions in Utah.

D.  Hydrocarbons

    1.  Area sources account for 92% of the hydrocarbon emissions.
        Over 60% of the hydrocarbon emissions are from transpor-
        tation sources.  Evaporative sources account for about 8%
        of the hydrocarbon emissions.  Petroleum refining and the
        metallurgical industry are the primary hydrocarbon point
        sources.

    2.  The Wasatch Front AQCR accounts for 64% of the hydrocarbon
        emissions in Utah.  Point sources in the Wasatch Front
        AQCR account for 99% of the point source hydrocarbon emis-
        sions in Utah.

E.  Carbon Monoxide

    1.  Area sources account for 97% of the carbon monoxide emis-
        sions.  About 90% of the carbon monoxide emissions are from
        transportation sources.  Point source emissions occur pri-
        marily from petroleum refining and the metallurgical
        industry with significant emissions also occurring from
        solid waste disposal and large fuel burning sources.
        Petroleum refineries and large metallurgical operations have
        carbon monoxide controls.

    2.  The Wasatch Front AQCR accounts for 65% of the carbon
        monoxide emissions in Utah.

                               SECTION III
                         SUMMARY OF GRID RESULTS

    The study area for this grid system consisted of Davis, Salt Lake, Utah
and Weber counties in the Wasatch Front Intrastate AQCR.  The only county
in the Wasatch Front AQCR not included in the grid system was Tooele county.
The grid system, using UTM coordinates, consisted of 312 square grids rang-
                       9       £   9
ing in size from 400 km • to 1.57 km .  The smaller grids were located in
the more densely populated areas.  Figures 2-8 are maps of the grid system.
Figure 2 is an overall map, while Figures 3-8 are maps of inset areas.
    The emission density maps, Figures 10-14, and Table 3 summarize the
                                                                         _3
results of the grid system study.  Table 3 listing the emission rates (10
tons/day) for the overall area and each inset area shows that the majority
of the emissions occur in the inset areas.  Table 3 shows that 67% of the
particulates, 27% of the sulfur dioxide, 59% of the nitrogen oxides, 78% of
the hydrocarbons and 76% of the carbon monoxide emissions occur in the inset
                                                                 _3
areas.  Figures 10-14 show the much higher emission densities (10   ton/day-
  2
mi ) that occur in the densely populated inset areas.
    Emissions for each grid were calculated by a computer program.  For each
grid, Table 4 lists the area (square miles) and the emission density for
each of the five major pollutants.  Additional data including a table for
each grid, listing emission densities for each pollutant and source type
has been calculated and is available.  The following source types are included
in the above table:

                                 SECTION  IV
                          POINT SOURCE METHODOLOGY

     The  purpose  of  the  point  source emission  inventory was to complete NEDS
  point  source  forms  on all  sources emitting over 25 tons/year (before control
  equipment) of any of the five major pollutants.  The Air Quality Section of
  the Utah State Division of Health conducted the point source data collection.
  Information on approximately  80 plants was furnished to GCA.  It was necessary
  to use 1970 data for about 6  sources as  no new data had been collected.  GCA
  designed a mailing  list of potential sources  in an effort to be sure that .all
  sources  had been located.  The mailing list was inspected by personnel of
  the Air  Quality  Section and they determined that it contained no additional
  sources.
     NEDS point source forms were completed for the following types of sources:
  solid  waste disposal facilities, electric power generation plants, feed and
  grain  elevators, phosphate fertilizer manufacturers, nitrate fertilizer
  manufacturers, copper smelting, iron and steel mills, gray iron foundries,
  secondary lead smelters, brick and clay  products, portland cement manufac-
  turers,  clay  sintering  plants, coal drying plants, concrete batch plants,
  lime manufacturing  plants, gypsum manufacturing plants, asphalt concrete
  plants,  perlite manufacturing plants, phosphate rock processing plants, sand
  and gravel processing plants, stone quarrys,  petroleum refineries and various
  establishments with boilers.  The largest individual sources were copper
  smelters, steel  plants, petroleum refineries  and electric power plants.
     NEDS point source forms were completed according to the directions in
"Guide  for Compiling a Comprehensive Emission  Inventory"  About 200 point
  I.D.*s were completed for  the 80 plants  included in this inventory.  Whenever
  possible, plant data was broken down into individual source data and entered
  on separate point I.D.  forms.  UTM coordinates to the nearest one-tenth of
  a kilometer were generally available from Utah personnel.  When necessary,
  GCA used 1/24,000 scale U.S.G.S. maps to obtain the UTM coordinates.  Stack
  data when available was recorded.  Pollution  control efficiencies reported
  by sources were almost always used.  In cases where the pollution control

-------
efficiency was unreasonable or not given, the efficiency was estimated from
              2           3
data in AP42-1  and AP42-2 .  Emission data from stack sampling was avail-
able from some sources and was always used.  For sources not reporting
emissions, the emissions were calculated from data in AP42-2.  Utah air pol-
lution control regulations were used to calculate allowable particulate
emissions for sources not located in the Wasatch Front Intrast,ate AQCR and
to calculate allowable sulfur dioxide emissions regardless of location.
Allowable particulate emissions for sources located in the Wasatch Front
                                                            4
Intrastate AQCR were calculated according to new regulations  issued by the
EPA in May 1973.  When the sulfur or ash content of a fuel was unavailable
it was assumed to be equal to the area source sulfur or ash content as
reported by Utah personnel.

                                SECTION V

                         AREA SOURCE METHODOLOGY


    The NEDS area source forms were completed by the Air Quality  Section  of
the Utah State Division of Health.   The methods  used generally  followed

chapter 5 of APTD 1135  and are outlined below.

  .  A.  Emission Estimates

        Emission estimates were calculated from  emission factors  found
        in AP42-12.   Aircraft emissions, were calculated  from data on
        LTO's, type  of aircraft and number of engines  per  plane.

    B.  Residential  Fuel

        Residential  use of bituminous coal, distillate oil and  wood
        was calculated from census  data on the number  of dwelling
        units using  each fuel in each county5, the  average number of
        rooms per dwelling unit in  Utah,5 degree day data  and the
        fuel consumption factors in APTD 1135.  Natural  gas use was
        obtained from dealers.

    C.  Commercial - Institutional  Fuel

        Commercial-institutional bituminous coal, distillate oil  and
        residual oil use was determined from the latest  Bureau  of
        Mines data.6,7  when necessary, the residential  and point
        source commercial-institutional fuel use was subtracted from
        the Bureau of Mines data before apportioning to  counties.     „
        The above fuel use was apportioned to counties by  population.
        Commercial-institutional natural gas used by county was
        obtained by  contacting natural gas dealers.

    D.  Industrial Fuel

        Industrial bituminous coal,  distillate oil  and residual oil
        use was obtained from the latest Bureau  of Mines data.6>7
        After subtracting industrial point source fuel usage the
        remaining fuel use was apportioned to counties by  manufactur-
        ing employees.^  Industrial  natural gas  usage  was  determined by

    E.  On Site Incineration and Open Burning

        On site incineration and open burning estimates were deter-
        mined from the national per  capita averages  as indicated  in
        APTD 1135*.   County and urban population was obtained from
        the 1970 census.^  Open burning by industrial  and  commercial-
        institutional sources is prohibited in Utah  so zeroes, were


                                     8

-------
    entered in the appropriate spaces.  Residential open burn-
    ing is prohibited in Davis, Salt Lake, Utah and Weber
    counties so zeroes were entered for open burning in those
    counties.

F.  Gasoline Fuel

    Data in "Vehicle Miles on Utah Highways 1972"9 and an    1Q
    additional table published by the Utah Highway Department
    was used to determine gasoline fuel used and measured vehicle
    miles.  The first publication contains VMT data by county
    and vehicle type but only includes state or federally aided
    roads.  The second publication includes all roads but only
    VMT data by road type for the whole state.  Local rural
    roads, not state or federally aided, account for 17% of the
    rural VMT so the county VMT data in the first publication
    was increased by 17% to include these roads.  Similarly,
    county VMT data for urban areas was increased by 30% in
    order to include local urban or municipal roads.

    Heavy vehicle gasoline usage was determined by subtracting
    the state diesel VMT from the state heavy vehicle VMT and
    then dividing by an average fuel consumption of 8.4 miles
    per gallon.  The state heavy vehicle gasoline was apportioned
    to counties by heavy vehicle VMT data.

    Light vehicle gasoline was determined by subtracting the
    heavy vehicle gasoline from the total taxed gasoline and
    then adding the gasoline used by government vehicles.  Light
    vehicle gasoline use was apportioned to counties by VMT
    data.

    Off highway gasoline consumption was calculated from the
    factors of 1000 gallons/tractor-year and 13 gallons/person .
    as specified in APTD 11351.  Data on tractors in Utah was
    obtained from the "Census of Agriculture".  Off highway
    gasoline was distributed to counties by population.

G.  Diesel Fuel

    On highway heavy vehicle diesel fuel consumption was obtained
    from the Utah State Tax Commission.  Heavy vehicle diesel fuel
    was apportioned to counties by county heavy vehicle VMT data.

    Off highway diesel fuel was calculated by using the factors
    of 1000 gallon/tractor year, 5000 gallons/year per non-
    building construction employee and 7.4 galIons/person as
    specified in APTD 1135.   In addition, it was known that a
    large open pit mining operation in Salt Lake county uses
    7,000,000 gallons/year or 1000 galIons/employee.  Therefore,
    an additional factor of 1000 gallon/mining employee was used.

-------
    Diesel fuel use for mining was only a small part of the
    total off highway diesel fuel use in all counties except
    Salt Lake County.  County off highway diesel fuel consump-
    tion was calculated directly from each of the above factors.

    Diesel fuel usage by railroads was obtained by contacting
    railroad companies.         .

H.  Aircraft

    Aircraft LTO cycles were determined from a study done by a
    university in Utah.  Also military airfields were contacted.

I.  Vessels

    Fuel use by vessels was expected to be a very small source
    of air pollution in Utah, so it was assumed to be zero.

J.  Evaporation

    Solvent purchased was determined from the factor of 2.7
    pounds per person per year for dry cleaning and the additional
    factors for surface coating and degreesing as listed in Table
    5.2 in APTD 1135.l

    Gasoline marketed was calculated by summing the previously
    calculated gasoline use.

K.  Measured Vehicle Miles

    The data in Vehicle Miles on Utah Highways was adjusted as
    previously discussed in the section on gasoline fuel and was
    used as measured vehicle miles.  Limited access road VMT was
    obtained from  VMT on interstate highways.  Rural road VMT
    were obtained from the rural category.   The suburban and
    urban VMT total were assumed to equal the urban category in
    Vehicle Miles on Utah Highways.  The suburban and urban road
    VMT were estimated by separating the inner city travel and
    the travel on the fringes of the city.

L.  Miscellaneous Sources

    1.  Dirt road vehicle miles traveled was estimated from
        data on the type of road,  length of road and the
        average number of vehicles/week for each type of road.
        Each county was  done separately by maps.

    2.  Dirt air strip data was obtained from the Utah
        Aeronautics Commission.
                                 10

-------
        3.  Construction land area was assumed to be the area
            likely to be damaged by wind as reported on U.S.
            Soil and Conservation maps.
        4.  Rock handling and storage data was obtained from
            replies to questionnaires by sources that were too
            small to be point sources.
        5.  Forest fire and stack burning data by county was
            obtained from the state forest service.
        6.  Frost control in Utah is very small and was
            assumed to be zero.
        7.  Structure fires were calculated by using the factor
            of 4 fires/1000 people as specified in APTD 1135.*
        8.  There is no coal refuse burning in Utah.
    GCA reviewed all area source categories.  However, the emission estimates
were not re-calculated.  The total off highway diesel fuel use exceeded the
published Bureau of Mines total by 82%;  Off highway diesel fuel use cal-
culated for mining was only a small contribution to all counties except Salt
Lake where it is known to be accurate.  Therefore, the numbers were not
changed.  Methods used to estimate suburban VMT may not have been accurate
and the data entered in NEDS forms should really be measured vehicle miles
travelled.  No revisions on the NEDS area source forms were made by GCA.
However, when the data was used for the grid system, suburban and urban VMT
were combined and treated as urban.

                                 SECTION VI
                          GRID SYSTEM METHODOLOGY

    The  purpose and results of the grid system study have been previously
described  in section III.  The purpose of this section is to describe the
methods  used to design the system and calculate the emissions.  Since the
grid data will be used in meteorological dispersion models, all grids must
be square.  Higher emissions usually occur in more densely populated areas,
so to better present the distribution of emissions, smaller grids were
drawn in those areas.  Maps showing the grid system are presented in Figure
2-8.  The  population in each grid was determined from 1970 census tract
     12,13,14
maps.  »   »•
    Figure  9 shows some of the census track that were used to determine the
population  of the grid in Figure 8.
    NEDS area source data, completed in August 1973 by the Air Quality
Section  of .the Utah State Division of Health was used extensively.  Individual
county totals for residential, commercial-institutional and industrial fuel
use was  apportioned to grids in the county by population.  County totals for
on site  incineration, solvent purchased, and gasoline marketed were also
apportioned to grids by population.  Off highway diesel fuel and gasoline
were apportioned to grids by area.  However, before apportioning off highway
diesel fuel, the 7,000,000 gallons used at the large open pit copper mine in
Salt Lake county were assigned to the appropriate grid as a point source.
    Data was obtained from the Air Quality Section of the Utah State Division
of Health on diesel fuel usage by railroads.  The data included the amounts
used in each-county in both railroad yards and on open tracks.  The diesel
fuel used in each county in railroad yards was apportioned to grids by the
relative size of the railroad yards on 1/24,000 scale U.S.G.S. maps.  Diesel
fuel used on open tracks was apportioned to grids by track miles.
    Airport LTO cycles for each of the 9 airports in the grid study area were
obtained from the Air Quality Section of the Utah State Division of Health.
Airport locations were determined from 1/24,000 scale U.S.G.S. maps and
assigned to the appropriate grids.
                                      12

-------
    Three methods were used to determine the vehicle miles travelled in the
grid areas.  Traffic flow maps   were used for grids 117-120 and 124, 125
in Ogden and grids 289, 291, 298, 299, 301, 302, and 305 in the Provo area.
Vehicle miles travelled in 239 traffic zones in the Salt Lake City area have
been published.    The grids for the present study were drawn over the 239
traffic zones and the VMT data was apportioned to grids 177, 179, 181, 186-
208, 211-230, 232, 237-2A6, 251-260.  County VMT data were apportioned to
all other grids by population.  In Salt Lake county, 71% of the VMT were
assigned to grids by the traffic zone method.
    Emissions from all of the above sources were calculated using area source
emission factors and methods obtained from the Environmental Protection
Agency in Durham, North Carolina.  Tables 5 and 6 list the emission factors
that were used.  Appendix A describes the methods used to calculate motor
vehicle emissions.
    A computer program was written and used to apportion sources to grids,
to calculate emissipns, and to do the summations and calculations necessary
for the final data output.  .Point source emissions which had been previously
calculated were assigned to grids by hand and included in the final computer
outputs and summations.

                        Motor Vehicle Emission  Calculations

      All data for the following calculations are  taken  from NEDS area source
 forms.  The first step in estimating motor vehicle  emissions is  to establish
 the mileage ratios for the different classes of vehicles:

     1)   Multiply gasoline fuel  for  light  vehicles times 1000 times 13.6 (mpg) ,
     2)   Multiply gasoline fuel  for  heavy  vehicles  times 1000 times 8.4 (mpg),
     3)   Multiply diesel  fuel  for  heavy vehicles  times 1000  times 5.0 (mpg).

         Add the products -  SUM  of vehicle miles: traveled.    (M_)
         Obtain ratio of  vehicle mile  total  for category of  vehicle.
                     (3)
                     SUM
    If any measured vehicle miles  are filled  in,  proceed as follows:
    Then multiply each  ration  from above  times each "Measured Vehicle Miles"
category, times  appropriate emission factor,  i.e.

    Limited Access Road  - miles  (M^)  times  10,000 times ILD times appropriate
emission factor  plus M^  times  10,000 R,jnr, times appropriate emission factor
plus M.. times  10,000 R,,nn times  appropriate emission factor.
	I	  times sum is the  emissions for limited access  roads in tons
453.6 2000
    Rural Roads  - miles  (M_)  times  10,000 times R,D times appropriate emission
factor plus M  times  10,000  times R,,-.,, times  appropriate emission factor plus
             K                      HL/Cj
M  times 10,000  Rrrnn  times appropriate emission factor.

,c, ,	2000     x sum is  the  emissions for rural roads in tons 	.
