                             PREFACE

          This report, which presents the emission inventory of
the Dallas Fort-Uorth metropolitan area, is another in a series of
studies ouiriivincj tha sources and emissions of air pollutants for
major metropolitan areas in the, country.  These reports provide
estimates of total emissions of oxides of sulfur, particulates,
carbon monoxide, hydrocarbons and oxides of nitrogen.   The emissions.
of these pollutants are delineated with respect to source type, season
of the year; as well as their geographical distribution v/ithir. the
area.  These surveys are also intended to determine the present level
of emissions and status of their control in metropolitan areas.

          The general procedure for these surveys is based on the
rapid survey technique.'  The Study Area is divided into grid zones
that serve as the basis for locating sources and reporting their ems--
si ons.  All sources of pollution are classified into tv;o general groups,
i.e., point sources and area sources.  All sources that emit large
quantities of air pollutants are considered individually and located
specifically vnthin the Area. This group, which generally contains about
fifty to one hundred sources, typically includes, large industries,  pov,:er
plants, and refuse burning facilities.  The remaining sources are consid-
ered collectively as area sources and their emissions are reported as
totals for grid zones.  This category includes motor vehicles, home heat-
ing, small industries, oil-site refuse burning, etc.  The emissions in
both cases are expressed in terms of tons of pollutant per average annual,

-------
          Emissions, for the most part, are estimated using various
•indicators of pollutant emissions and average emission factors that
                     o
are related to those.'1  This moans that invcrpiatlon and data are
collected on fuel consumption, refuse disposal, vehicle miles, and
gasoline consumption as well as various industrial production rates.
These are then translated into omission estimates, in r;:u>t cases, by
use of average emission factors.  These factors, represent average
emission rates for a particular industry or fuel type.  Because of
the inherent differences in type of equipment, operating rates, con-
trol equipment, and efficiency of operation among the plants and fuel
users within a given category, the application of the emission factors
to any individual plant or even a smaller number of similar plants or
processes may result in a discrepancy between the actual and estimated
emissions.  However, the estimates of total pollutants from all source:

              The inforrr.atlov, and dnta presented in this report were
    gathered in cooperation with the Dallas, Dallas County, and Fort
    Worth Health Departments and the Texas State Air Control Board
    during a survey conducted in January, 1969.  Tha data obtained in
    this stud;' is renrer.onto.tive of 1967 and emission est.ir.ates pre-
    sented herein should be considered as describing the level2 anu con-
    ditions during 1967.
    
              For the purposes of this survey, a Study Area consisting
    of ten counties in the Dallas-Fort llorth metropolitan area was selected.
    The Study Area is made up of tv/o Standard Metropolitan Statistical
    Areas which cover 8,000 square miles and included a 1057 population of
    over two million people.
    
              The Study Area was subdivided into 68 grid zones ranging in
    size from 25 square kilometers in the heavily populated and industrial-
    ized areas to 1600 square kilometers in the outlying areas.
    
              Although specific individual source information was obtained
    for over 90 sources, only the largest 51 were considered as point
    sources.   These 51 sources are the most significant emitters in the Study

                           SUMMARY OF EMISSIONS
              An er.tirv.'ted 1.,410.000 tons of the five major pollutants
    are emitted annually in the Study Area.  All major sources excluding
    organic solvent evaporation were included in this survey.  Breakdowns
    of this total with respect to specific pollutants as v/oll as the type
    of sources emitting these pollutants are given in Table 1 and are sum-
    marized below.

    (4) Ellis, (5)'Johnson, (6)Kaufman, (7) Parker,  (8) Rockwell,  (9)Tar-
    rant. and (10) :!ise.  Nearly 80 percent of the Study Area's  1967 popu-
    lation of 2,186,000 were residing in the urban area of Dallas  and
    Tarrant Counties.  The I960 and 1967 populations of each of  the ten
    counties are presented in Table 2.  Comparison uf 19:^0 and 1967 populati;
    shows an increase of 26 percent as compared to an increase of  10.9 per-
    cent for the United States during the same period.
    
              The area is generally void of na.jor heavy industrial areas.
    Hov.'evcr, v.'hatever industry there is. is located  in Dallas and  Tarrant
    Counties.
    
              The Dallas-Fort Worth Study Area is situated in the  north
    central part of the state and is located on mostly level or  slightly
    rolling terrain.  The climate is temperate but the v/eather can be ex-
    treme.  The periods of extreme are usually of short duration,  however.
    The prevailing v/incJs are southerly averaging around 11 niph.  Strong
    winds frcn the north occur frequently during the vn'nter nonths, but are

               Grid coordinates  based  on  the  Universal  Transverse  Mercator
     system were  used in, this  study  to show  the  geographical  distribution
    •of sources and emissions.   As shown  in  Figure  2,  the  Study Area  v/as
     divided into 68 grids  of  four different  sizes  -  25,  100,  400,  and 1600
     square kilometers,.
    
               Different size  grids  are used  to  limit  the  number of grid
     zones  and  yet allow a  satisfactory definition  of  geographical  gradation
     of emissions in areas  where the: majority of pollution occurs.  For
     this  reason  the 2!5  square  kilometer  grids are  used in the downtown areas,
     where  the  density of emissions  v.'ould change abruptly  within short dis-
     tances.  In  areas primarily rural  in nature,  the  use  of  small  zones  are
     not as important.
    
               As illustrated  in Figure 2 each grid line  is identified by  a
     coordinate number.   The north-south  and  the east-west cordinates are
     expressed  in meters.
    
               The point sources are identified  by  both horizontal  and vertical
     coordinates  to the  nearest  100  meters.   The grids  are identified by  the

               All the sources of air pollution'considered in this
     survey fall into one of the following four categories:
               1.  Fuel combustion in stationary sources
               2.  Transporation
               3.  Refuse Disposal
               4.  Industrial process losses
               Each of these categories  is  considered individually in
     this  section end also in t!ie subsequent section where data sources
     are given and .methods of calculation are discussed,
    
               It is important to note that the estimates presented herein
     and especially in the process loss category are, in most cases, partial
     totals.   This stems from the inavailability of emission factors as
     well  as  appropriate production data..  In the case of hydrocarbon emis-
     sions where gasoline evaporation was included but solvent evaporation
     was not, the totals are considerably lower than actual values.  The
     results  should be viewed with these limitations in mind.
    
     Fuel  Combustion by Stationary Sources^
               Table.  3 presents the fuel consumption within the Study Area.
     As- shown in the table, natural gas is the primary fuel used in the area.
     During 1267, over 206 billion cubic feet of gas were consumed within.the
     Study Area which represents over 2 X 10'^ DTU of'energy.
    
               The industries and steam-electric utilities are the largest
     fuel  users in the Area.  During 1967, they consumed more than 8'1 percent
     of the natural gas.
    
               I'atural ncir,, for all practical purposes, is the only fuel i;ced
     for residential home heating.  There are homes heated by electricity but

              The emissions resulting from fuel combustion are summarized
    in Table 4.  The use of fuels is the second largest source of nitrogen
    oxides, accounting for almost 30 percent of the total.
    
    Transporation
              In all, three types of transportation sources were considered.
    Those; were motor vehicles, aircraft., and railroads.  Table 5 summarise:;
    vehicle miles of travel and fuel consumption data which were used to
    calculate emissions from motor vehicles.  Nearly 35.0 million vehicle
    miles of travel occur each day vnthir, the Study Area of v/hich about 2.2
    percent is accounted for by riiesel powered vehicles.  Tin's rate of travel
    accounts for a fuel consumption of 988 million gallons of gasoline and
    55 million gallons of diesel fuel annually.  Approximately 80 percent of
    all travel occurs in Dallas and Tarrant Counties.
    
              The air traffic activity at FAA controlled airports is sum-
    marized in Table G.  Approximately 583,000 itinerant operations and
    333,000 local operations took place during 1967.
    
            .  A local operation is defined as a take-off or landing that
    originates and terminates at the same airport.  An itinerant operation
    is one that either originates or terminates at the airport. '  Air car-
    rier flights are primarily commercial while general aviation includes all
    private and pleasure flights.              •    •  .
    
              The emissions from transportation sources are summarized in
    Tables 7 and G. 'Road vehicles are by far the most significant source
    of pollution.  In 19G7, the accounted for 97 percent of the carbon monoxide,

     (of the total transportation enissions).  Diesel fuel pov/ered vehicles  '
     wore, an important sources of hydrocarbons and oxides of Nitrogen.
    
               The emissions fron aircraft, although small, may be signi-
     cant in that they occur at one location rather than throughout the
    -area as is the case for motor vehicles.  tVrlssions from railroads v:eru
     mainly considered in Dallas and Tarrant Counties.

               The estimated tonnages of refuse disposal is summarized in
     Table 9.  Nearly all of t!v; refuse is disposed of by landfill operations.
     Hoy/ever, in the  eight outer counties, most of the refuse is disposed of
     by burning in open dumps or by on-site incineration.  The emissions from
     refuse burning are summarized in Table 10.

    FUG! Consumnti_orijby_ Statipnary  Sources
              The  local  air  pollution agencies were contacted as to the
    use of fuels in the  major industrial, commercial  and institutional
    estnblishnente  under thnir  jurisdiction.  The large natural gas users
    were considered individually as  point sources.   These consisted entirely
    of steam-electric pov/er  plants.  The balance  of the fuel was distributed
    to the three area source  categories of fuel  consumption:  (1) residential
    (2) co'.Xiercic;!-institutional  and (3) industrial.
    
              The  amount of-fuel  burned for  home  heating purposes v/as cal-
    culated using  the procedure described in the  Rapid Survey Technique.
    The method includes  such  variables, as total  annual degree days, average
    number of rooms nor  dwelling unit,  and the number of units using each
    type of fuel.
    
              Commercial-Institutional  and Industrial fuel use consumption
    were available  by county  and were considered  entirely as area sources.-^
    
    Transoortation
              Emissions from  tin's  category v:ero found by the application
    of two different methods  depending o^ the type of information available.
    
              In Dallas and Fort 1/orth Counties,  vehicle mile data were
    available through'  a Transoortation Study done in 19GG.J  These vehicle
    miles of travel were  apportioned- to the grid  system by means of traffic
    

    -------
                The vehicle miles v.'erc updated to 1967 and adjusted to  account
      for the fact that no* all secondary roads were included.
    
                In the other eight counties > vehicle mile info mat ion was  not
      avallab!». and t/nr; or; sol-in:? connn-Pticii" v:cs ur.«:t! to fine! vrv.iculcr
      emissions.   The gasoline consumed in each county was apportioned  on
      n grid basis by population.
    
                Emissions from diesel powered vehicles were determined  by
      diesel fuel consumption in each county.   These emissions were appor-
      tioned on a nrid basis by assuming they were proportional to gasoline
      emissions.
    
      _Refuso Di s n c s a 1
    
                Emissions in this category were determined by disposal  rates
      supplied by the city of Dallas Health Department and the Texas State
      Health Department.  However, these rates reflect only refuse that v/as
      collected.   Little information v/as available for on-site incineration,
      backyard burning and industrial waste disposal.  Thus emissions in this
      category are considered as conservative estimates.
    
      Industrial  Process
                •The various industries in the Area were contacted as to
      their fuel use and production rates.  From.this information, indus-
      trial process losses were determined for processes where emission factors
      wore available. .The totals in this category are by no moans complete
    :  since time did not permit a thorough contacting of all industry in the-:
      Area.  However, information on most of the major industries v/as available

              The following is a brief description  of  the  number  and
    types of inu'.'rtry contnctod in the Dollns  and Fort Uorth  areas.
    There was one sulfuric .acid plant and one  refinery v/hich  was  not
    equipped with a waste heat boiler.  There  are three  cement  plants
    in the area v/ith varying ranges of participate  dust  collection
    efficiencies.  In adc'i i:ion, there ore over 15 concrete or asohaltic
    batching plants for vhich production data  were  available.

              Table 13 presents the total emissions  from  all  sources  fnr
    each of the 63 grids in the Dallas-Fort Worth Study Area.   The  previous
    sections of the report describe hov/ each  category v/as apportioned by
    grid.  These subtotals v/ere added to  the  point sources  to  arrive  at
    the total omissions per day.  The Appendix  describes  the  procedure
    for the calculation of the annual as  well as the sunnier and winter emis-
    sion averages for a point source.  However, the  same  procedure, with

                           EMISSION  DENSITY
              Emission  densities  on  a  grid  basis were  obtained  by

    This gives  an emission  density  in tons of  pollutant  per  square
    mile per  day.   Figures  5  through  9 present the  results of  those
