AIR POLLUTANT EMISSION INVE~~ORY
INTRODUCTI ON
,'"
This report is a compilation of air pollutant emissions in the
Cincirmati - Hamil ton - I,.!iddletown metropolitan areas.
TIle ob j ecti ves
of this emission inventory were to determine the quantity',of the various
air pollutants emitted as well as their geographical and seasonal
variations.
This was done by using a modified form of the rapid
ch. 1
survey te n1quc.
The Study Area was divided into a grid coordinate
system and the emission quantities were reported in terms of tons of
pollutant per grid on an average annual day. average summer day, and
average winter day.
The pollutants considered in this survey ,...ere sulfur oxides, parti-
culates, carbon monoxide, hydrocarbons, and oxides of nitrogen.
Data
"
presented herein were gC?thered mainly by the acknmvledged state and


local agencies and are representative' of 1967 unless other\dse noted.
STUDY AREA
,The Study Area,. prC'sented in Figure 1, consists of Cincinnati and


the surrounding counties (Boone, Campbell, and Kenton in Kentucky; ,
Dearborn in Indiana; and \\Tarren,: Clermont, and the balance of Hami 1 ton
in Ohio) as 'vell as the Hamilton - ~1iddleto\m area which consists of
Butler County in Ohio.
The area occupies 2,620 squar'(; miles and
contains an estimated 1967 population of :.,658,880 which 'is a 13
percent increase over the 1960 population (See Table 1).

TOPOGRAPHY
08
The entire Cincinnati !.1etropolitan area is part of an upland plain
about 900 feet above sea level, with the floodplain of the Ohio some
800 feet 100'1er.
Downtown Cincinnati is located in the basin formed by
the junction of the ~j:i.ll Creek and Licking River valleys with the flood
plain of the Ohio.
The basin area and flood plains are surrounded by steep bluffs
°rising 200 to 400 feet to the general plateau level.
TI1ese b luffs are
cut frequently by the valleys of small tributary streams which produce
a setting of promontories and steep hills.
111e Hamilton - ~1iddletown area is located about 2S 1i\iles north of
o the Cincinnati area \\'hile the Darton Standard ~Ietropolitan Statistical
~
Area (SMSA) is S3 miles north of Cincinnati.
TI1erc are no other large
industrial or populated areas within 7S miles.
GENERAL CLI~~TOLOGY
TI1e climate in the Cincinnati area is basically continental with a
wide range oin temperature.
The Cincinnati area is subjected to frequent
changes in weather due to the passage of numerous cyclonic storms °in
the winter and spring and thunderstorms in the summE~r.
The temperatures
I
i
I
! .
range from an all-time high of 1090 in the summer to 170 obelO\~ zero in
the winter.
On the average, a temperature of 340 could be expected in
Cincinnati in the winter.
"I
The prevai ling south to south\\'cst Hinds on the western side of the I

Bermuda high during the summer carry \\'a1'l11, moist air from the Gulf of
Gt..;
.

-------
. .
Mexico up the ~'ississippi,~nd Ohio valleys into the Cincinnati area.
This gives the area a high frequency of thunderstorms. . The wind
. .
speed averages about 11 mph in the winter and about 7.5 mph in the
summer.
GRID COORDINATE SYSTH1
For the purposes of this survey. the Study Area was divided into
62 grids based on Universal Transverse ?-tercator Projection (Ul1.~).
Three grid sizes of 20,000 meters, 10,000 meters, Clnd 5,000 meters ,...ere
utilized for delineatiug emissions of the sulfur.oxides, particulates,
--
carbon monoxide, hydrocarbons, and nitrogen oxides (Figure 2).
. SW.~'ARY OF RESULTS
The follO\...ing is a brief summary of pollutant emissions and
sources in the Cincinnati - Hamil ton - ~Iic1dletown Study Area:
1.
Sulfur oxides (about 428,000 tons per year) are
emitted primarily from stationary fuel combustion.
The combustion of coal, mainly from steam electric
power plants, contributed 91 percen~; industrial
processes, 7 percent; and transportation, less
than 1 percent.
2. - Coal combustion accounted for more than 6~ percent
of the total particulate emission of 122,470 tons
per year. . Trallsportation sources contributed
6.~~ percent; industrial processes, 23 percent;
and refuse burning, 3.5 percent.

3.
The major source of carbon monoxide (537,000 tons
per year) was the operation of gasoline powered
motor vehicles which emitted 90 percent of the
total emissions.
Coal combustion in commercial and
institutional buildings accounted for another 4 percent.
Sources such as refuse burning, industrial process
and fuel combustion in stationary sources accounted
for the remaining 6 percent.
4.
Oxidcs of nitrogen (129,820 tons per year) were
discharged primarily from coal combustion in steam
electric utilities (45 percent) and in, industrial
plants (13 percent).
Transportation sources account
for 27 percent.
5.
Motor vehicles account for appro'ximately 6S percent
of the 55,340 tons of .hydrocarbons emitted.
Stationary
fuel combustion accounted for 18 percent of the total
hydrocarbons included in this survey (solvent evaporation
was not included).
The emissIons of pollutants discharged to the air in the Stud)'
Area are summarized in Table 2.
Tne validity of these results are
dependent on the accuracy and applicability of the e:mi.ssion factors
2
used. . . These factors, for the most part, represent averap.e emission
rates for a particular industry or fuel type.
Because of the inherent
differences in type of equipment, operating rates, control equipment,
and efficienc)' of operation among the plants and fuel users \vi thin

a given category, the appllcation of the emission factors to any
. .
individual plant or even a smaller number of similar plants or
. .
processes ina)' result b a discrepancy between the actual and the
estimated emissions.
~10wever, the estimates of total poll)Jtants from
all sources in the study area should be fairly accurate since the
emission factors are based on average conditions.
Some of the estim~tcs in this report are reported to five
significant figures, but because of the limitation of the data involved,
they should be considered accurate to no more than two.
E~fISSIONS BY CATEGORY
For the purposes af cO!11piling the basic data and emission estimates,
the air pollutant sources were classified into the following four
categories:
1.
Fuel combustion in stationary sources
2.
Transportation
3~
Solid-waste disposal
4.
Industrial process losses
Fuel Combustion. in Stationary Sources
All three major fuels are consumed within the Stud)' Area Ivith
coal being the most significant.
In 1967, coal accounted for
2.77 x 1014 Btu I s or 72 percent of the total energy input while
natural gcs accounted for 24 percent anJ fuel oil the remaining
. 4 percent..

Study Area used natural gas as the heating fuel.
Coal was used in 11
percent, fuel oil in 17 percent, and other type of fuel \Vere used in
the remaining I percent as shown in Table 7.
ll1e areal variaticn in the home heating fuel use can be seen
from Table 8.
Natural gas is used mostly in the heavily pop~lated
areas of Cincinnati - C.ovington - !\cwpon and lIamil ton - ~Iiddleto\in.
Coal is used mainly in the older sections of the City of Cincinnati,
while fuel oil is used more in the rural areas.
SOlile d\Vellings in

while that of fuel oii is about average.
E~issions fTom Fuel Cowbustion in Stationary Sources
Air pollutant emissions resulting from fuel cO!TIbustion in stationary
sources are listed in Table 9 and by jurisdiction in Table 10.
Al though
coal accounts for only 72 percent of the total fuel ener~YJ it is
responsible for 99.8 percent of the suI fur oxides J 98 percent of the

'Transportation
Three types of transportation sources of air p,)l1ution are
considered in this survey - road vehicles, aircraft. and railroads.
Road vehicles ,.hich are by far the most im110rtant source of air

Emissions from road vehicles "ere determined feom a transportation
study done by the Ohio - Kentucky -Indiana. Regional Transy>ortation
Commission (OK1) in 1965.
Vehicle mi Ie totals ".'ere obtained by county

Thl:se figures \\ere obtained from the various
railroads in the Study Area.
Emissions from Transportation Sources
The quanti ties of pollutants attributed to transportation sources
is summariz{'d in Table~. 13 and 14.
Hore than 482,000 tons of carbon
monoxide, 43,000 tons (If hydrocarbons, and over 34,OaO tons of oxides
of nitrogen were cmitt0d in the Study Area.
Motor vehicles account for over 98 percent of the total carbon
monoxide, 84 percent of the total hydrocarbons, and 70 percent of the
total nitrogen oxides.

Aircraft account for a small percentage of the total transportDtion
e111issions.
Hmo'over, because of their liinited land area, the emission
density is high and th~s, they become an important point source.

,Solid Waste Disposal
. ,
.
Approximately 1.52 million tons of refuse were generated during
1967 in the Study Area.
lhis was determined by assuming a per capita
9
disposal rate of five pounds of refuse per day.
The disposal of this
. refuse is divided fairly evenly bct,':cen landfills, nunicipal incineration.
and open dumps (See 1a)le 15).
Any balance was assumed to be backyard
burning.
Landfills account.~d for 30 percent; municipal incineration. 31
percent; open dumps. 30 percent; and backyard burning, 9 percent of
o the total refuse disposed.
At lancifills no burning occurred.
Tne amount of refuse burned at
the 40 dumps varied.
Some burned 100 percent of the refuse collected
while others did not burn at alL
A total of over 12,000 tons of
..
carbon monoxide. 4.400 tons of particulate matter, and 1,600 tons of
nitrogen oxides were e~itted from solid waste dispos3l practices in
the Study Area.
TIlese totals and a breakdo~1 hy jurisdiction are
presented in Table 16.
Industrial Process Losses
The Cincinnati.. I1amil ton - HiddletOl'.'I1 Study Area is for the most
part void of heavy industry and thus emissions from this cate~ory did
not constitute a major portion of the total.
As is t.he case in any
emission inventory, the lack of emission factors for some industrial
processes did not a11o\\' for a complete estimation of process emissions
e.g. soap manufacture.

system shown in Figure 2."
An immediate need for the apportionment by grid is for the
purpose of dcsirnatingAir Quality Control Regions.
111e emissions of each pollutant were divided into two source
subgroups - point and area sources.
TIle 62 point sources were
identified by source category, and horizontal and vertic:l.l coor-
dinates.
They are presented in Table 17, along with emissions for
the five pollutants fe:r an average annual, winter, and summer day.
The appendix presents the method for calculating these three
averages since it differs from the Rapid Survey Technique.
The emissions for area sourccs on the annual, ,'inter and
.
sUr.1mer average bases are shOi>11 in Table 18.
The ca1culation of
these averages is similar to that presented in the ~rpcndix for
~,
point sources.
Emmission Densities by Grid
Emission densities on a grid basis were obtained by summing the
annual area and point 50urce emissions for each gr~d.
This total,
"divided by the grid area, gives an emission densityi.n tons per
square mile per day. "Figures 4 through 8 present the emission
density maps for thc five survcycd pollutants.
Figure 4 presents the emission density for sulfur oxides.
As
can be seen the densities arc hi"~h in a P.lumbcr of grids located in
the sparsely populated areas of noome, CCir.lpbell, and Dccuborn
counties.
This is primarily"due to the fact t.hat the steam electric
,..'
.
'~ ;:'
v ~J

-------
.'"
pmITer plunts which are the major source of sulfur oxides, are
located here.
In Figure 5 the particulate emission density has been delineated.
This too is high in t:'e outer areas because of thc effect of the
power pl.ants.
The carbon monoxide densities are shmm in Figure 6.
This shows
that the emissions arl} highest in the downtO\m areas of Cincinnati,
Hamilton, Middleto\',~ ;}s would be expected. . However, as one moves
out of the cities the densities are higher in a north-south direction
rather than in an eas ~:-west.
This is due to the predominance of
heavily traveled road~, in this <1i rection such as th~ interstate
freeNay 1-75.
.
Because motor vehicles account for a large percentage of the
.,
total hydrocarbons, tr.e same effect is observed for hydrocarbon
densi ties as \Vas founc for carbon monoxide, i. e. 'high in the
cities, radiating in a north-south rather than an east-\\'est direction.
Since power piants account for almost half the total of the
nitrogen oxides, the high density locations are similar .to those of
sulfur oxide and particulates, as can be seen from Figure
8.
