PREFt\CE
Thi 5 report, VI!!i ch presents t~1f~ !:n1i ssi on inventory of the
Houston-Galveston metropolitan area, is another in a series of
,.
studies outlininCf the sources and err:issions of air pollutants
for l:1ajor metropolitan areas in the country. These rerorts
provide estimates of total emissions of oxides of sulfur, oxides
of nitrogen, hydrocarbons, carbon monoxi de and parti cul ate iila tter.
The emissions 6f these pollutants are delineated with rcs~ect
to source tyre. season of the year as \"ell (\s their geo~rarhical
distril;ution v:ithin the area.. These surveys are also int2nded to
determine the rresetlt level ,of emissions and status of their control.
. The general procedure for these surveys is hased on the raoid
survey technique.l The Study Area is divided into grid zones that
serve as the basis for locating sources and reporting their emissions.
fdl sources of rollutants are divided into t\'JO suhgroups--point and
area sources. Sources that emit large Quantities of air ~ollut(\nts
are considered individually and located specifically within the area.
This latter group \.:hich generally contains about fifty to one hundrpn
sources typically includes large industries, ~c\."er nlants, and c",ntral
refuse burning facilities. The remaining Multitude of sources are
considered collectively as area sources anrl their emissions are re-
ported as totals for.grid zones. This category includes motor vc~1iclr.s.
home heating, smaller industries, on-site refuse burninq etc. The
emissions in both cases are expressed in terms of tons of pollutants
for an average annual, summer, and winter day.
Emissions for the most part are csti~ated using various indicators
of pollutant e~issions and average emission factors that are related
to these. This r1eans that infor;natiofl and data are collr.ctecl on fuel

STUDY AREA
"
The Study Plrea for the emission survey of the Houston-
Galveston t'1etrof)olitan Area consists of eight counties-8razoria~.
Chambers, Fort !3cnd, Galveston, Harris, Liherty, r1ontgomery and
Haller. The eight county area is located in the south-eastern
region of the State of Texas. Figure 1 shows the location of
the Houston-Galveston Study Area relative to other cities in\its ,
vi ci ni ty . Fi gure 2 represents a more deta i 1 ed dral.''; ng of the
Study Area.
The climate of the Study Area is predominately marine. The
JJ
terrain includes numerous small steams and bay~ which, together
with the Gulf of Mexico and Galvestrin Bay, favor the development
of both ground and advective fog. Prevailing winds are from the
southeast and south, except in January, when frequent passages
. of high pressure areas bring invasions of polar air and prevail-
ing northerly winds.
Although the total area is slightly over 7800 square miles,
only some 200 square miles are at present urbanized. Over 80
percent of the Study Area's 2 million people reside in Harris
County, and 7 percent live in Galveston County. The other six
counties are mostly rural. The 1960 and 1967 population of each
of the ten counties are presented in Table 2. Comparison of the
1960 and 1967 population for the entire United States sh'o\"s an
increase of 10.9 percent where as the Houston Study Area increased
27 percent in the same period.
The manufacturing industries (Table 3) in the Study Area ~
are highly diversified but uith a lot of chemically orientated
. facilities. In addition to the eight major oil refineries, there
are petrocherr.ical r1ants, ce!!lent manufacturing, ceffee roastin~,
grain milling, .acic;l plants and aero-space facilities.

of sources and emissions.
As shmm in Fi gure 3 t the Study I~rea \iaS
divided into 61 grids of four different sizes - 25tlOOt400 and lGOO
square kilometers.
Different size grids are used to limit the number of grid zones
and yet allO\'J a satisfacoty definition of geographical gradation of
emissions in areas \Jhere the majority of pollution occurs.
For this
reason, the 25 ki lometer gri ds are used in the dO\imtO\'m areas \'Jhere
the emission densities whould change abruptly \1ithin short distances.
In areas primarily rural in nature, the use of small zones are not
as important.
As illustrated in Figure 3"each grid line is identified by a
coordinate number.
The north-south and the east-west coordinates are
expressed in meters.
The point sources in the Study Area are identified by both hor-
izontal and vertical coordinates to the nearest 100 meters.
The gri ds
are identified by the coordinates of their geographical center.

EMISSIONS BY CATEGORY
For the purposes of compiling the basic data and emission estimates,
the air pollutant sources were classified into the following four categories:
1.
2.
3.
4.
Fuel Consumption in stationa~y
Transportation
Solid-waste disposal
Industrial process losses
sources
Each of these categories are considered individually in this section
where data sources are given and methods of calculation are discussed.
It is important to note that the estimates presented herein are esti-
mates of partial totals. This stems from the inavailability of certain
types of data. It was especially difficult to gather information on hydro-
carbon emissions and natural gas consumption for the Houston Area. The
results should be viewed with these limitations in mind.
Fuel Combustion in Stationary Sources
Although all the three major fuels are consumed within the Study Area,
natural gas is the most significant. As shown in Tables 4 through 6, approx-
imately one half million tons of coal, 1.6 million barrels of fuel oil, and
895 trillion cubic feet of natural gas were consumed in the Study Area. The
breakdown of fuel consumption by user category and by jurisdiction is also
shown in these tables.
The nine steam-electric generating plants within the Study Area con-
sume 25 percent of the natural gas while industry uses aDproximately 70
percent.
All the. coal used in the Study Area was made into coke and used in the
production of steel.
The fuel oil was consumed ~y railroads and vessels in the Study Area.
The railroads used about .8 million barrels of distillate while the 4000
shi;s per year in the ship channel burned an 'equal amount of residual fuel
oiL
'J
-------
Average values for the sulfur and ash contents of the fuels may be
found in Table 7. la, 11
~
Emissions From Fuel Consumption
Air pollutant emissions resulting from fuel consumption in station-
ary sources are listed in Table 8. The emissions are presented for indus-
trial, steam-electric utility, residential, and commercial sources.
Emissions due to coal were not included in this section but were put
in process emissions. Oil emissions were placed with transportation sources.
Natural gas accounted for approximately 100 thousand tons of pollutants.
The largest portion of this being nitrogen oxides.
Data Sources
Fuel consumption data for the Study Area were obtained from a variety
of sources. Natural gas numbers were gotten from natural gas companies
and pipe line companies. Also some information was furnished by individual
industries. The Houston Light and Power Company supplied us with the con-
sumption of their power plants.
Coal was estimated from published coke production figures.
Distillate fuel oil estimates were obtained from five or six of the
larger railroads in the Study Area. The residual fuel oil was generated by
a factor recieved from the Mari time Association in Houston. It also supplied
the number of ships using the ship channel yearly.
Transportation
"
Four types of transportation sources of air pollution are considered in
the survey--road vehicles, aircraft, vessels and railroads. Road vehicles,
which are by far the most significant source of air pollution in this cate-
gory, are further subdivided according to type of fuel--gasoline or diesel.
c
-------
Road Vehicles
The miles of travel by motor vehicles in the Study Area are sum-
marized in Table 9. Vehicle miles data for the city of Houston was ob-
tained from a transportation study done by the Texas A & M University.
The vehicle miles for all other jurisdictions in the Study Area were esti-
mated by gasoline consumption and proportioned into grids by population.
Travel by diesel powered vehicles ~/as estimated from state wide fuel
consumption figures. It was found approximately 2 percent of the vehicle
miles in the Area are diesel. Vehicle miles by diesel were also proportioned
by population.
Aircraft
Tables 11 shows the air traffic activity at the three largest airports
in the Study Area. Total aircraft operations were supplied by the Federal
Aviation Administration for H. P. Hobby Airport while the others were gotten
from personal 'communications. An operation is defined as either a takeoff
or a landing. Aircraft accounted for less than 25 percent of the total trans-
portation emissions for any pollutant.
Railroads and Vessels
Railroads consume about 25 million gallons of diesel fuel. This was
obtained from various railroads in the Area. . River vessels consumed about
25 million gallons of residual fuel oil. Because of the sulfur content of the
fuel oil, sulfur oxides from vessels are significant when compared to emis-
sions from other transportation sources, but other pollutants emitted by
vessels and railroad are smaT1.
-------
Solid Waste Disposal
c
Approximately 2 million tons of refuse were generated during 1967
in the Study Area. Table 13 presents a solid waste balance for the Houston
Galveston Study Area, .showing the various methods of disposal and the
quantities disposed of by each method. Landfills accounted for 28 percent;
municipal and on-site incineration 17 percent; dumps 32 percent; and on-site
burning 23 percent of the total refuse disposed.
Table 14 shows the air pollutant emissions from solid-waste disposal.
The largest single sources were a municipal incinerator in Houston and"burn-
ing dumps in Galveston County.
Industrial Process Emissions
Table 3 shows selected manufacturing establishments in the Area by SMSA
for 1960. The largest percentage of the industry in the Area is located
. along the ship~~ channel in the city of Houston and Harris County. There are
also industrial areas in Galveston County and Brazoria County. . Emissions
from industrial process losses are shown in Table 15.

EI'iISSION BY GRID
For the prupose of modeling the air pollutant er,lissions in the
Study l\rea, the resulting emissions \'lere apportioned on the grid
reference system sho\'Jn in Fi gure 3.
The emissions of each pollutant \'Jere divided into tVIO source
subgroups - point and area sources.
The SO point sources Here
identified by source category, grid number and horizontal and vertical
coordinates.
Figure 4 ShOHS the location of major point sources in
the Study Area.
The point sources are presented in Table 25, along
with emissions for the five pollutants for an average annual, winter,
and summer day.
The emissions for all sources on the annual, \'/inter and sur.uner
basis are shown in Table 21.
The calculation of these averages is
similar to those done for the point sources.
