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:

INTRODUCTION
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.

As shov.'n In Finure 1, the Study Area encompasses the
cities of Dalles and ten counties: (1) Collin, (2) Dallas, (3) Ponton,
(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

COORDINATE SYSTEM
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
-------
DISCUSSION OF RESULTS
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,

72 percent of the particulates and 91 percent of the sulfur oxides
(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.
Jndustrial Process Losses
Emissions in this category v;ere found by applying emission
factors to production rate data for the various industries. The emis-
sions are presented in Table 11.

METHODOLOGY
The fo'ilowing discussion is a summary of procedures used

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.
'line secondary metal foundries v.'^re surveyed in the Study
Area. Tiris includes 'Ic.-ad, gray iroi;, brass s hronze and steel. Figure

Area.

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
