I. INTRODUCTION
A. BACKGROUND OF PROGRAM
A primary purpose of the Federal Air Quality Act of 1967 was to
provide for planning and control programs on a regional basis. More recently,
the Environmental Protection Agency has required the preparation, adoption
and submittal of implementation plans for meeting national ambient air stan-
dards by each of the states.
An important first step in implementation planning is the carrying
out of an emissions inventory to determine the principal pollution sources
in the state. The present report presents the results of an emission in-
ventory for the state of Wyoming.
B. DESCRIPTION OF PROGRAM
The study program is concerned directly with establishing annual
emission levels for the following five pollutants:
Particulates,
Sulfur Dioxide,
Carbon Monoxide,
Hydrocarbons,
and
Nitrogen Oxides
The annual emission levels for each of the pollutants are estab-
lished for each of the 23 counties in Wyoming as well as for the three
principal cities, Cheyenne, Laramie and Casper. In addition, totals for
these pollutants are presented for the three Federal Air Quality Control
Regions in Wyoming. Table I presents a listing of these regions together
with the respective counties comprising them. Figure 1 presents a map of
Wyoming, showing their geographic locations.
For each geographic breakdown discussed above (region, county,
city) the emission levels for each of the 5 pollutants are presented by
source category. These categories are:

. Stationary Fuel Combustion Sources - which include power
plants, as well as industrial, institutional, commercial,
and residential facilities.
. Transportation Sources - these include both gasoline and
diesel-powered motor vehicles, aircraft and railroads. Also
included are evaporative losses from gasoline marketing.
. Solid Waste Disposal - municipal and private dumps which
practice open burning, together with residential, commercial,
institutional and industrial incineration and open burning
comprise this source category. There are no municipal i
incinerators in Wyoming.
. Process Losses - these include stone crushing and processing,
various minerals industries, asphalt and concrete batch
plants, meat packing, organic and inorganic chemical faci-
lities and several oil refineries. Also included are evap-
orative losses from petroleum bulk storage tanks, solvent
evaporation in paints and varnishes, and solvent evaporation
from dry cleaning.
C. USE OF THE INVENTORY
The data presented in this survey are not to be interpreted as
absolute values. The pollutant emissions obtained should be considered as
estimates to be used in defining the extent and distribution of air pollu-
tant emissions in Wyoming. The data are accurate enough to be used in
conjunction with ambient air quality measurements in the preparation of
an implementation plan for meeting national ambient air standards.
-------
II. SUMMARY
Tables 2 through 7 summarize the results of the emissions inventory
program for Wyoming. Emissions from all pollutant source categories are
presented and totalled for each of the Air Quality Control regions as well
as for the three principal urban centers; Cheyenne, Casper and Laramie.
For each of the three regions, however, emissions from the following point
source categories were grouped together under the heading "Commercial,
Institutional and Industrial - Other Point Sources":
All commercial, institutional and industrial point sources
whose emissions were reported rather than computer calculated.
The combustion of sour gas at oil fields and refineries.
Open burning of petroleum sludges primarily at oil fields.
Examination of these tables indicates that a primary source of parti-
culate emissions is process losses from industrial point sources. These
include stone crushing and processing, various minerals industries, asphalt
and concrete batch plants, meat packing, organic and inorganic chemical
facilities and several oil fields and refineries. In addition, when sig-
nificant quantities of coal are utilized, such is the case in regions 241
and 243, coal combustion is also a major source of particulates.
Coal combustion is also a primary source of SO^ emissions in region
241, region 243, and the City of Laramie. Sour natural gas, which is
burned in large quantities in many oil refineries in Wyoming, is another
significant S0« source. The combustion of residual oil and industrial
process losses are the other two major sources of S09 emissions.
Emissions of carbon monoxide and hydrocarbons in Wyoming originate
from three major sources: automobiles, on-site incineration, and industrial
process losses. In region 242, conical burners used to incinerate wood
scrap from lumber and saw mills also comprise a major source of CO emis-
sions, and to a lesser degree, hydrocarbon emissions. In addition, the
evaporation of gasoline during marketing and handling activities result
in significant hydrocarbon emissions in all three of the Air Quality
Control regions.
-------
Emissions of oxides of nitrogen are attributed to three major
sources in Wyoming: automobiles, sour natural gas burned at oil fields
and refineries, and coal combustion. As mentioned earlier, significant
quantities of coal are used in regions 241 (1.85 million tons) and re-
gions 243 (1.73 million tons), and so coal is a major source of NO emis-
X
sions in these regions. The burning of sour natural gas at refineries
in regions 241 and 243, and outside the cities of Cheyenne and Casper,
account for significant emission levels of NO in these respective areas,

III. AREA DESCRIPTION
Wyoming is the 9th largest state in the Union. Its 97,914 square
miles are divided into four geographic regions. These are the Great
Plains in the Southeast, the Black Hills in the Northeast, the Rockies
in the West and between these regions the Intertnountain Basin. The only
farming area in Wyoming is in the Great Plains. The Rocky Mountains and
the Black Hills are rich in mineral and petroleum deposits, but the Inter-
mouitain Basin is a desert area. The major industries are petroleum pro-
duction and refining, uranium mining and reduction, soda ash production
from Trona ore, and lumber production. The major agricultural product
is livestock.
The meteorological data of the area show that it is a cool dry
area with good ventilation. A 30 year record at Lander indicates mean
maximum temperatures ranging from 31 degrees in January to 86 degrees in
July. The corresponding mean minimum temperatures are 8 degrees in Jan-
uary and 55 degrees in July. Degree heating days within the state range
from over 11,000 to less than 7200 depending on elevation. An average
annual value, based on records from Casper, Cheyenne, Lander, and Sheridan,
is 7564 degree heating days.
Casper, the most industrialized city in Wyoming, has an average
wind speed of 13.3 miles per hour with 5 percent of the observations being
calm, 8 percent being less than 4 miles per hour and 24 percent being less
than 8 miles per hour. In contrast Los Angeles has an average wind speed
of 6.8 miles per hour with 13 percent of the observations being calm, 28
percent being under 4 miles per hour and 63 percent being under 8 miles
per hour.
Precipitation in Wyoming, by climatic region, ranges from 10 to
24 inches with the populated areas having 10 to 15 inches of precipita-
tion annually.

IV. METHODOLOGY
A. DEFINITION OF POINT AND AREA SOURCES
This emissions inventory considers two classifications of emis-
sions sources, point and area sources. Point sources are generally large
establishments whose emissions are significant enough to warrant individual
consideration. On the other hand, sources whose emissions are too small
to be considered individually are accounted for collectively as an area
source.
1. Point Sources
The Federal Register (Volume 36, No. 67, Part II, Appendix C)
lists those major pollutant source categories which are to be classified as
point sources, independent of size. Wyoming contains the following indus-
trial categories which are included in the Federal listing:
Fertilizers
Feed and Grain Handling and Processing
Asphaltic Concrete Batching
Bricks and Related Clay Refractories
Cement
Concrete Batching
Rock, Gravel, and Sand Quarrying and Processing
Open Burning Dumps
Steam Electric Power Plants
Petroleum Storage Tanks
Petroleum Refining and Petrochemical Operations
In addition to the above industrial classifications, all fuel
combustion sources were considered point sources if one or more of the
following air pollution emission criteria were met:
. Annual Particulate Emissions of 5 tons or Greater
. Annual Sulfur Dioxide Emissions of 10 tons or Greater
. Annual Nitrogen Oxide Emissions of 25 tons or Greater
. Annual Carbon Monoxide Emissions of 25 tons or Greater
. Annual Hydrocarbon Emissions of 25 tons or Greater
2. Area Sources
Area sources are defined as those combustion and process
sources which in themselves are too small to constitute a point source, but
14
-------
when considered collectively, will significantly contribute to the total
emissions of the study area.
The following presents a listing of those categories con-
sidered as area sources in Wyoming. These categories, however, exclude
those individual sources which have emissions large enough to classify
them as point sources,
Fuel Combustion Stationary Sources
. Residential heating - combustion of natural gas and some coal
accounts for emissions from residential heating in Wyoming.
. Commercial, institutional and industrial space heating - area
source emissions in this category result from the burning of
natural gas and distillate oil. The coal and residual oil used
in Wyoming in this category are essentially all accounted for
by point sources.
Process Losses
. Dry cleaning establishments.
. Utilization of paints and varnishes.
Solid Waste Disposal.
. On Site Open Burning of Municipal Refuse.
. On Site Incineration of Municipal Refuse.
Transportation
. Motor Vehicles - both gasoline and diesel powered vehicles
are included.
. Locomotives
. Aircraft
. Evaporative losses from gasoline marketing

As discussed earlier, a fuel combustion source, other
than specified in the Federal Listing of major industrial categories, was
classified as a point source if its annual emission level for particulate,
or SOy was equal to or greater than 5 or 10 tons, respectively, or if the
CO, NO or hydrocarbon emissions were equal to or greater than 25 tons
X
per year. In compiling this mailing list, however, there were several
categories (such as schools, hospitals, hotels, a variety of residential,
commercial, institutional, Federal and civic buildings, together with many
miscellaneous industries) which, because of a lack of information pertain-
ing to the type and quantity of fuel consumed, could not definitely be
classified as point sources. Working criteria for the completion of the
point source mailing list were then established and are presented below:
Manufacturing and Commercial Establishments - more than 25 employees
Schools and Colleges - more than 700 students
Hospitals - more than 100 beds.
These criteria were modified as required in the light of
knowledge of either State or GCA personnel as well as data available from
the individual sources.
b. Response to Questionnaires
A mailing list of 246 addresses was compiled by GCA to
be contacted by the Industrial Hygiene Section of the State of Wyoming. In
addition, one utility company was contacted directly by Region VIII of EPA
to obtain the information required in the point source estimate form. Table
9 gives a review of the questionnaires sent out and the number and percent
of returned forms. Copies of these questionnaires are presented in the appendix.
Table 9 shows that of the 247 questionnaires mailed, 61.5
percent were eventually completed and returned. A number of questionnaires
were initially sent in incomplete or with erroneous information and a tele-
phone recontacting effort was undertaken by the State of Wyoming so that
these questionnaires could be properly completed.
In addition, the State also contacted selected point
sources who failed to return their questionnaires.

2. Data Analysis
Analysis of the data from the completed questionnaires con-
sisted of two essential phases: (a) the choice and use of a coordinate
system for defining the locations of point sources, and (b) the transform-
ing of raw data from the questionnaires into the form required for input
to the computer program used by the Office of Air Programs (OAF) for the
final emissions inventory calculations.
a. Coordinate System
The Universal Transverse Mercator (UTM) coordinate sys-
tem was chosen for Wyoming because: (a) the system is widely used in
meteorological modeling, (b) maps with the UTM grids denoted are readily
available from the U. S. Geological Survey (USGC), and (c) the UTM system
does not suffer from grid irregularities to the same extent as do most
other systems, notably, the township/section system used in Wyoming. In
general, the locations of individual point sources were determined to
within one kilometer in either (flat projection) dimension.
b. Computer Input Forms
The details of the data manipulation required for data
transformation will not be discussed here. Instead, some critical assump-
tions and statements of policy regarding data treatment will be reviewed
in the following material.
1. Stack Parameters - information concerning stack
heights, diameters, and flow conditions are given only for sources emit-
ting 50 tons or more per year of any pollutant. In most cases where such
data are given, they are based on estimates using OAP recommended procedures.
2. Process Weights - because sufficient data were not
available from the questionnaires, maximum process weights were not estimated.
3. Fuel Characteristics - in almost all cases, these
were given on the returned questionnaires. In those few cases where such
data were not given, assumptions were made based on data from the returned
questionnaires.
19
-------
4. Pollution Control Efficiency - major point sources
gave control efficiencies almost without exception, but many smaller
sources did not have such data. The values given by McGraw and DupreyCrablelQRef.il)
were normally used where the data were missing.
5. Emissions - some respondents included estimates of
actual emissions on their returned questionnaires. These data were used if
they showed reasonable agreement with estimates obtained by the use of
emission factors. Otherwise, the estimated values based on emission fac-
tors were used.
6. Allowable emissions - allowable emissions for par-
ticulate as defined by Wyoming law were hand calculated for all regulated
point sources in the state. In addition, Federal model emissions were
calculated for point sources within the city limits of Cheyenne, Laramie,
and Casper. The Federal model sulfur dioxide emissions were calculated
for combustion sources by assuming 80 percent removal.
At the request of EPA-Denver, and with concurrence
of the Wyoming Department of Industrial Hygiene, State allowable particu-
late emissions are not included for any natural gas burning point sources.
7. Oil Field and Refinery Sumps and Flares - oil sumps
resulting from cleaning the tanks in well fields are occasionally burned.
In this operation, it is assumed that 50 percent of the oil is burned with
the resulting S0» being estimated from the relationship:
S02 (pounds) <= 157 S
where S is the percent sulfur in the crude oil. Particulates from the burn-
ing sumps are estimated to be 30 pounds per 1000 gallons of burned oil.
Gas burned in refinery and oil field flares is as-
sumed to contain 1.0 percent sulfur unless otherwise stated. Hand calcu-
lated emissions are only made for SO and no emission factors are
available for the other contaminants. For all other gas burning point
sources, estimates of S0? are made for all gas containing greater than
20
-------
0.0005 percent sulfur. These estimates are included in the hand-calcu-
lated emissions in addition to providing an emission factor to the com-
bustion process. This is done because there is no provision in the com-
puter program to estimate S0~ from a source burning sour (high sulfur)
natural gas.
All flares, boilers, heaters, treaters, and engines
in oil well operations have an SIC Code of 2911, process code 00, and a
type code of 02. A distinction is made between engines in the emission
factor assigned to the fuel consumption.
C. AREA SOURCES
1. References
References used to compile data for the consumption and ap-
portionment of area source fuel, solid waste and evaporative losses in
Wyoming are summarized in Table 10. These references include both local
and state data together with data compiled by private companies and by
Federal agencies such as the Census Bureau, Bureau of Commerce and the
Bureau of Mines.
2. Data Analysis
This section discusses the methodology utilized in estimating
and apportioning fuel, solid waste and process area source emissions. Be-
cause a variety of area source categories utilize a number of different
types of fuels, we have included Table 11 which summarizes those fuel con-
suming area source categories and the types of fuels utilized. The en-
suing discussion of stationary fuel combustion and transportation area
sources is based around this table.
a. Stationary Fuel Combustion
i. Coal
(25)
The Bureau of Mines has published data for annual
coal consumption in Wyoming (3,809,000 tons) which is in excellent agree-
ment (within 3%) with the total coal consumed by point sources in the
state (3,668,053 tons). There are, however, some small users of resi-

dential coal (22,100 tons) in two counties in the State. We have, there-
fore, concluded that most coal consumption in Wyoming is accounted for by
point sources, and that area source coal consumption is small, limited
to the two counties utilizing coal for residential heating. This is con-
firmed by communications with various state officials and coal producers
familiar with coal usage in Wyoming.
ii. Residual Oil
Returned questionnaires indicate that residual oil
consumed annually by point sources (38,422,000 gallons) significantly
(3)
exceeds the Bureau of Commerce consumption total for Wyoming (2,406,000
gallons). This difference reflects the heavy use of residual oil by oil
related industries which likely consume significant quantities of oil pro-
duced at their plant. The residual oil consumed by point sources, exclud-
ing these oil related industries (3,654,000 gallons), however, is in good
agreement with the Bureau of Commerce consumption total, considering that
the Bureau of Commerce data are for the year 1967. We have, therefore,
concluded that residual oil consumption in Wyoming was accounted for by
point sources and that area source consumption is essentially zero. This
is confirmed by communications with various state officials familiar with
residual oil usage in Wyoming.
iii. Distillate Oil
Area source distillate oil consumption for space-
heating in Wyoming is insignificant due to the widespread use of natural
gas. This has been established by communications with various state and
local personnel intimately familiar with fuel consumption patterns in
Wyoming. In addition, further verification is given by (he Bureau of Com-
merce annual consumption total for distillate oils (~ 26,000,000 gal-
lons) which is substantially lower than the combined point source
(~ 15,000,000 gallons) and diesel fuel (~ 50,000,000 gallons) annual dis-
tillate consumption totals for Wyoming.
The quantity of kerosene utilized annually in Wyoming
(3)
(967,000 gallons) was determined from the 1967 Census of Business. '
25
-------
This kerosene was considered to be fuel for commercial and institutional
space heating and was apportioned by county according to the volume sales
statistics published in the above reference. Emissions were calculated
based upon the emission factors for industrial and commercial distillate
fuel oil as presented by McGraw and Duprey.
iv. Natural Gas
Total natural gas purchased from utility companies
in Wyoming in 1969 (61,459 x 10 SCF) was reported by the Public Service
(23)
Commission. From this total, the natural gas purchased by point
sources (29,570 x 10 SCF) from utilities (including natural gas used as
a raw material feed stock in the manufacture of urea and liquid petroleum
products) was subtracted to obtain the natural gas utilized in the state
for residential, commercial, institutional and industrial space heating
(31,900 x 10 SCF). Natural gas consumption in Laramie County as pro-
vided by Cheyenne Light, Fuel and Power Co., indicates that the fuel used
for residential space heating is about equal to the fuel used in commercial,
institutional and industrial units. Therefore, gas consumption for space
heating by commercial, institutional and industrial units was assumed to
be the same as for residential units (~ 16,000 x 10 SCF).
As an alternative technique, area source natural gas
3 estimated us
cribed by Bierbaum and Gedgaudas.
consumption was also estimated using the following relationship as des-
(1)
Total Gas Usage = (D.U.) x [ p^Jeg day] * (deg days)
where D.U. is dwelling units and degree days represent the average heating
degree days.
The resulting value using this technique (16,700 x 10
SCF), and multiplying by two to obtain residential plus commercial, insti-
tutional and industrial (33,400 x 10 SCF) checked well (within 5 percent)
with the alternative approach. These statewide consumption totals were
apportioned to the counties and cities (Cheyenne, Casper and Laramie) by
population.
26
-------
Emissions were calculated based upon the emission
factors presented by McGraw and Duprey.
v. Liquid Petroleum Gas
The state consumption total (69,918,000 gallons) was
(27)
obtained from the Bureau of Minesv and apportioned by population data
to the three Federal Air Quality Control Regions and the cities of Chey-
enee, Laramie and Casper. Emissions were calculated based upon the emis-
sion factors for domestic and commercial propane as presented by McGraw
and Duprey. The emission factor for nitrogen oxide was assumed to be
23 pounds per thousand gallons, based on the assumption that 80 percent
LPG was utilized by domestic sources and 20 percent by commercial sources.
The emissions from LPG combustion appear in Tables
2-7 which summarize emissions for the 3 Air Quality Control Regions and
the urban areas of Cheyenne, Laramie and Casper. However, because the
emissions from LPG combustion are small, they were not included in the
area source emissions in the accompanying computer printout.
b. Transportation
i. Gasoline Powered Motor Vehicles
Emissions from gasoline powered motor vehicles were
calculated using the vehicle mile method described by Bierbaum and Ged-
gaudas, Air Pollutant Emission Inventory Techniques, 1969. The emis-
sion factors developed by this method are presented in Table 16 of this
text and a sample calculation is shown in the appendix. Daily vehicle
mile data for each county in the State of Wyoming were obtained from the
Planning and Research Division of the Wyoming State Highway Department.
These data were provided for 6 classes of roads for local, foreign and
commercial traffic. The following estimates of the average vehicle speed
for each class of road were also obtained from the Wyoming State Highway
Department.
Average
Road Type Road Class Vehicle Speed
Federal Aid Interstate Road 01,02 60 mph
Federal Aid Primary Road 03,04 45 mph
Federal Aid Secondary Roads 05,06,07,08 45 mph
27
-------
Average
Road Type Road Class Vehicle Speed
State Roads 09,10 24 mph
Local Rural Roads 11 18 mph
Local Urban or Municipal Roads 12 ; 10 mps
The ratio of vehicles registered in the State of
Wyoming by year of manufacture were obtained from the Albany County Motor
Vehicle Registration Office. The registration of 2092 vehicles was selec-
ted from approximately 11,000 registrations-and the proportions of auto-
mobiles by year of manufacture calculated.
1963 or older 23.6 percent
1964 through 1967 42.1 percent
1968 through 1970 34.3 percent
The method of estimating NOV emissions from auto-
CD
mobiles described by Bierbaum (1969) was modified to include the effects
of the altitude of the State as described by R. L. Duprey, Compilation of
Air Pollution Emission Factors, 1968. The average altitude for the State
was considered to be approximately the same as Denver, Colorado; therefore,
the NOV correction factors given by Duprey for Denver were used.
x
Table A in the Appendix shows the daily vehicle
miles by road class for each county. Also, Tables B, C, and D present the
daily emissions by road class, for each county in Wyoming.
ii. Diesel Powered Motor Vehicles
The emissions from diesel powered motor vehicles
were calculated from the vehicle mile data obtained from the Wyoming State
(24")
Highway Department.v ' The State Highway Department estimates that 80
percent of all traffic classified commercial in the Wyoming Traffic Data
Book for 1970 were propelled by diesel engines. The method used to cal-
culate emissions for diesel powered vehicles is described by Bierbaum (1969).
Table E in the Appendix presents diesel fuel con-
sumption (vehicle-miles and gallons of diesel fuel) by county.
28
-------
iii. Railroads
The estimates of diesel fuel used by railroads in
the State of Wyoming were obtained from:
The Union Pacific Railroad
The University of Wyoming
The Union Pacific Railroad reported their own estim-
ates of the diesel fuel they consumed in the State by county. The fuel used
by the Burlington and Northern Railroad was estimated to be 25 percent of
that used by Union Pacific Railroad by Professor Stillwell of the Petroleum
Engineering Department of the University of Wyoming.
Table F in the Appendix summarizes the fuel con-
sumption of these two railroads by county. Included in this table is a
comparison between the Burlington Northern consumption totals as estimated
by Professor Stillwell and as reported by Burlington Northern. The figures
from Burlington Northern were received too late to be utilized in this study.
iv. Aircraft
Airport operations data were obtained from the Wyo-
ming State Highway Department. Total landing and takeoff operations were
tabulated for each major airport, as well as the type of equipment.
Emissions were calculated using the method described by McGraw and Duprey.
Table G in the Appendix shows the number of annual aircraft operations in
Wyoming.
v. Gasoline Marketing
The emission of hydrocarbons due to gasoline market-
ing was estimated using the method described by M. J. McGraw and R. L.
Duprey, Compilation of Air Pollutant Emission Factors, 1971. ' Gasoline
sales for each county were obtained from the Wyoming State Revenue Department
and the emission calculated based upon 21 pounds of hydrocarbons for each
1000 gallons of gasoline sold.
c. Solid Waste Disposal
The State of Wyoming recently compiled information on
the quantity of refuse collected and the handling and treatment procedures
29
-------
for each municipal dump and sanitary landfill in the state. Those dumps
which practiced open burning were included as point sources. In assuming
that 7 Ibs./person per day of municipal refuse (which includes household,
commercial and institutional refuse) is generated, the total refuse which
remains uncollected can be estimated for each county by simply subtract-
ing the refuse collected from the quantity generated. The uncollected
refuse was assumed to be disposed of in backyard single chamber incinera-
tors without primary burners which are in wide use in Wyoming. The emis-
sion factors of McGraw and Duprey (1971) were assigned to these incinera-
tors. A summary of annual solid waste disposal is presented in Table H
of the Appendix.
d. Process Losses
i. Dry Cleaning
McGraw and Duprey have estimated that hydro-
carbon emissions from dry cleaning operations in cold climates such as that
of Wyoming average 2.7 pounds per person per day. This value was used for.
the determination of emissions from this source for the counties and the
major urban areas of Wyoming.
ii. Surface Coating Operations
This category includes chiefly the application of
paints and varnishes for protective and/or decorative purposes. No state
surface coating consumption data were available for Wyoming, but a national
total for paint and varnish was obtained from the U. S. Paint and Varnish
( 26^
Association . From this total and the national population, it was
determined that per capita consumption of paint and varnish is 0.0248 tons/
(2)
person per year. This value was used with North Dakota population datav
to determine the paint and varnish used in the pertinent geographical areas
/ r\ f\
in the state. Information from the Paint and Varnish Association in-
dicated that the solvent content of these coatings averaged about 62.5 per-
cent. In determining the hydrocarbon emissions from solvent evaporation,
it was assumed that all of the solvent was hydrocarbon and that it all
evaporated.

V. COMPUTER PRINTOUT
The detailed results of the emissions inventory are given in the computer
printout which is forwarded in a separate binder.
The printout is arranged by Air Quality Region, and for each Region,
there is a point source printout and an area source printout. The point
source printout presents detailed data and also summaries of annual emissions
by source category for each Political Jurisdiction (county) within the
Region; these summaries are tabbed, "#8". Similarly, the area source print-
out presents detailed data and also aummaries of annual emissions by source
category for each Political Jurisdiction (county) within the Region; these
summaries are tabbed, "#18".
Detailed notes on the data provided in the printout are now pre-
sented. These are arranged to follow the sequence of the printout sheets
and should be read in conjunction with general explanations given in the
Methodology section of this report. Numbered tabs are attached to the print-
out pages to indicate the first page of each listing.
A. POINT SOURCE PRINTOUT

Standard Industrial Classifications and Process Codes were assigned
to each source as shown in Table 12. Where more than one source had the
same classification and Process Code, consecutive Site numbers were assigned
to such sources.
The counties corresponding to the Political Jurisdiction numbers
listed are shown in Table 13.

Each source was classified by Type as either Process, Boiler or
Solid Waste. All fuel combustion sources were classified as Boiler al-
though these included a small number of process combustion sources such as
kilns, flares and burning of petroleum sludge.
Listing #3
The Shifts/Day figure is based on the ratio of the reported total
operating hours to 8760 (total hours in a year).
The Use Factor figure is based on the ratio of maximum capacity
to actual average operating rate. In the case of fuel combustion sources,
average operating rate is the ratio of reported annual BTU consumption to
reported annual hours operated.
The maximum and normal Process Weight Rates are expressed in
pounds per hour.
Listing #4
This listing is self-explanatory and no further comments will be
included here.
Listing #5
This listing gives the totals of fuels consumed during the year
within the Region.
Listing #6
Computer calculated emissions were made for fuel combustion sources
only, using the fuel totals and emission factor set numbers indicated.
Solid Waste and Process sources were hand calculated. In addition, emissions
from the combustion of sour gas and the open burning of petroleum sludge were
hand calculated. These hand calculations were based on annual solid waste,
process, and combustion totals together with emission factors from McGraw
and Duprey (Table 10, No. 11).
37
-------
The Uncontrolled figure is the sum of the computer calculated
and hand calculated figures.
The Controlled figure is the uncontrolled figure minus the
product of the Control Efficiency and the uncontrolled figure.
The Device Identification number corresponds to the control device
listed in Table 14 of this report.
The Allowable particulate emission values are those permitted
by the State of Wyoming. There are no state values for allowable SO- emissions.
Listing #7
The same notes apply as for Listing #6, except that no control
devices or allowable emissions are considered.
Listing #8
This listing gives total point source emissions for each Political Juris-
diction within the Region. The totals are presented by source category
and fuel totals are included for combustion sources. The industrial-commer-
cial-institutional fuel combustion category marked "other" is comprised of
emissions from the combustion of sour gas in both oil refineries and indus-
try, and the open burning of petroleum sludge in oil refineries.
Refuse totals are also presented for each of the solid waste cate-
gories. The solid waste category marked, "other" is comprised of conical
burners which consume wood scrap from lumber and saw mills.
Listing #9
The Allowable emissions of particulate and SO- based on the Federal
model standards as published in the Federal Register, Volume 36, Number 67,
on Wednesday, April 7, 1971, are presented for all regulated point sources
in Wyoming.
The zone numbers specify whether the point source is located in
zone 12 or zone 13 of the Universal Transverse Mercator (UTM) coordinate
system.

Listings #10. til, #12, #13, #14
Each listing presents emissions of one pollutant by Political
Jurisdiction and consists of four printout tables. Emissions entitled,
"Apportioned Emissions" (Table 1), and "Calculated Emissions",(Table 2) were
computer calculated and based on emission factors presented below in Table
15 of this report. Note that in Table 2 of the printout, the columns marked
"Diesel Motor Vehicles," and "Motor Vehicles 25 MPH and 45 MPH," have zero
emissions since these categories are included in Table 3 of the printout.
Table 3 of the printout, entitled, "Additional Emissions" was
hand calculated. The basis for these hand calculations has been discussed in
the Methodology Section (IV) of this report. Note that the explanation to
the row numbers in Table 3 of the printout are presented below in Table 16
of this report.
Table 4 of the printout sums up the emissions from the preceding 3
tables. "Calculated 1" refers to Table 1; "Calculated 2" refers to Table 2,
and "additional" refers to Table 3.
All emissions in these four tables are expressed in Tons per Year.
Listing #15
Printout Table 5 shows only the computed-calculated emission and
fuel consumption totals for the Region. The source categories and appro-
priate units for the fuel totals corresponding to rows 1 through 22 are
presented below in Table 15. All emissions are expressed in Tons per Year.
Total area source emissions are summarized in Listing #18.

Sample Calculation of Automotive Emissions
The percentages of total hydrocarbon emissions for controlled and uncon-
trolled vehicles as presented by Bierbaum are:
Uncontrolled 1963 Controls 1968 Controls
Exhaust 48% 63% 39%
Crank Case 30% 8% 0%
Fuel and Carburetor 22% 29% 61%
The following equations show the method used to determine the emissions
from gasoline-powered motor vehicles:
