Glossary of Terms
The following terms are defined as they were used in this report or its appendixes.
Activity level: Unit indicating the combined effect of population,
annual hours of use, average-rated horsepower, and load factor.
Determined by multiplying the population x annual hours of use x
horsepower x load factor. The activity level is also the product of the
population and the per-source usage rate.
Airshed: A geographical area which, because of topography, meteorology, and
climate, shares the same air mass.
Air toxic: A compound in the air capable of causing adverse health effects For
the purpose of this report, the air toxics examined were limited to
known or suspected carcinogens.
Aldehydes: A class of fast-reacting organic compounds containing oxygen,
hydrogen, and carbon. They contain the group -CHO
Annual hours of use: Average number of hours a given
equipment type is used in one year.
Attainment area: A region that meets the National Ambient Air Quality Standauls for a
criteria pollutant under the Clean Air Act.
Control technology: A combination of measures designated to achieve
the aggregate reduction of emissions.
Crankcase: The part of the engine that surrounds the crankshaft; usually the lower
section of the cylinder block.
Crankcase emissions: Pollution emitted into the atmosphere from any portion of the engine
crankcase ventilating or lubricating system.
Crankcase emissions A system of passages designed to convey gases from and/or to the
control system: crankcase of an engine. The system may or may not include means to
regulate the flow(s)
Criteria pollutants: The Clean Air Act required the Environmental Protection Agency to set
air quality standards for common and widespread pollutants after
preparing "criteria documents" summarizing scientific knowledge on
their health effects. Today there are standards in effect for six "criteria
polutants". sulfur dioxide, carbon monoxide, particulates, nitrogen
dioxide, ozone and lead.

-------
Diurnal emissions:
Fuel vapors emitted as a result of a specified increase in fuel tank
temperature in a specified time. For the purposes of this report, diurnal
losses are those vapor emissions which occur while the equipment is not
operating and are attributable to natural changes in ambient conditions
(temperature, pressure, etc.).
Duty cycle:
The ratio of the time "on" of a device or system divided by the total
cycle time (i.e., "on" plus time "off'). For a device that normally runs
intermittently rather than continuously; the amount of time a device
operates as opposed to its idle time
Emission factor:
Measure of the rate at which a particular type of equipment emits a
particular pollutant under normal operating conditions. Emission factois
are commonly mass-based and expressed in units of mass per unit of
work.
Emissions inventory: A detailed listing of the amounts of pollution generated by different
sources in an area during a specific period of time.
Evaporative emissions: Evaporative emissions are losses due to evaporation of unhurried
fuel. For the purposes of this report, evaporative emissions are subdivided
into four groups: hoat soak, diurnal, resting-loss, and running-loss
emissions.
Four-stroke cycle:
Horsepower,
used average rated:
Hot-soak emissions:
Load factor:
The four-piston strokes—intake, compression, power, and exhaust—that
make up the complete cycle of events in the four-stroke-cycle engine.
Also called four cycle and four stroke.
The average of the maximum horsepower ratings for the engines
in a given type of equipment.
Hot soak emissions are those emissions which occur after the equipment
has been turned off and attributalbe to the elevated temperature of the
equipment (e.g., evaporation from the carburetor bowl).
The ratio of the engine power output during typical operating conditions
to the engine rated horsepower.
National Ambient Air Section 109 of the Clean Air Act requires EPA to set nationwide
Quality Standards standards, the National Ambient Air Quality Standards, for widespread
(NAAQS): air pollutants. Currently, six pollutants are regulated by
primary and secondary NAAQS—carbon monoxide, lead, nitrogen
dioxide, ozone, particulate matter (PM-10), and sulfur dioxide See
Criteria Pollutants.

-------
Nonattainment area:
A region that falls to meet Clean Air Act primary ambient air standards
are designated as nonattainment areas. Most major cities in the United
States arc nonattainment areas for one or more of the criteria pollutants
These duty air regions are subject to strict controls to bring them into
compliance with the standaids.
Nonroad vehicles:
Vehicles or items of machinery that use, an internal combustion engine
but are not regulated as motor vehicles or airplanes under the Clean Air
Act. Construction equipment is an examples of nonroad vehicles
Per-source use rate:
Unit indicating the combined effect of annual hours of use, average-
rated horsepower, and load factor Deteimined by multiplyuig the
annual hours of use x horsepower x load factor.
Population:
Total number of units of a given equipment or engine type at a given
point in time.
Refueling emissions: Hydrocarbon emissions that can occur during filling of the vehicle fuel
tank. For the purposes of this report, there are two components of
refueling emissions: spillage and vapor displacement.
Reid Vapor Pressure: The vapor pressure of gasoline at 100°F (37.8°C) determined in a
special bomb in the presence of a volume of air which occupies four
times the volume of liquid fuel (ASTM procedure D 323).
Running loss emissions: Running loss emissions are those emissions which do not pass
tlirough the combustion chamber while the source is in operation
Spillage emissions: Spillage emissions, or spillage, are those emissions resulting from
spilled fuel incurred during the refueling process.
Steady-state: Constant operating conditions with no variation in fuel supply or load
A condition in which circuit values remain essentially constant,
occurring after all initial transients or fluctuating conditions have
settled down. Steady-state exists when periodic (or constant)
vehicle responses to periodic (or constant) control and/or
disturbance inputs do not change over an arbitiarily long time.
The motion responses in steady-state are referred to as steady-
state responses. This definition does not require the vehicle to
be operating in a straight line or on a level road surface It can
also be in a turn of constant radius or on a road surface.
Transient: A phenomenon caused in a system by a sudden change in conditions
and which persists for a relatively short time after the change.
DRAFT - October 1991
A-5

-------
Transient state:
Transient state exists when the motion responses, the external forces
relative to the vehicle, or the control positions are changing with time.
Vapor displacement: Vapor displacement emissions, or "displacement", are those emissions
which result from displacing fuel vapors in the fuel tank with liquid
fuel.
Volatile Organic Any compound containing carbon and hydrogen or containing carbon
Compounds (VOC): and hydrogen in combination with any other element which has a vapor
pressure of 1.5 pounds per square inch absolute or greater under actual
storage conditions.

Appendix B. Ozone Formation
This appendix provides a brief explanation f the process by which ozone is
formed, followed by a list of other sources expanding on the role of NO, and VOCs
Description
The prediction of ozone (03) levels and the development of control stiutegies foi
ozone have been complicated by the fact that ozone is not directly emitted. Rather, it is
formed in the lower atmosphere in the presence of sunlight through a complex seiies ot
reactions between volatile organic compounds (VOCs), oxides of nitrogen (NOx), and
ambient oxygen. The concentrations of ozone and its precursors are dynamic anil nonlinear.
Thus, ozone concentrations are not necessarily additive, but depend on the concentrations of
all compounds involved in atmospheric chemistry. VOCs are emitted by antliropogenic
sources, such as evaporation of gasoline and solvents, and by biogenic sources such as
vegetation. Individual VOC species differ widely in their capacity to generate ozone. NOx is
formed primarily by combustion processes and can contribute to either the creation or
destruction of ozone, depending on the amount of VOCs present.
Ozone is produced when atomic oxygen (O) reacts with molecular oxygen (02) in this
reaction:
O + 02 + M -> 03 + M
where M is a tliird body that removes the energy of the reaction and stabilizes the 03
molecule. The atomic oxygen necessary for this reaction is produced primaiily from the
photodissociation of NOz, according to this reaction.
N02 + hv -> NO + O
The photon (hv) in this reaction is in the blue-violet end of the visible spectrum which, when
absorbed, produces a brown color. This is why a brown haze is associated with ozone
pollution, even though ozone itself is a colorless gas In the above reactions, NOx is involved
in creating ozone.
DRAFT - October 1991
B-l

-------
However, in the absence of other reactants, the ozone and nitrogen oxide (NO)
produced in these reactions will combine to form nitrogen dioxide and molecular oxygen
NO + 03 —» N02 + 02
Thus, oxides of nitrogen participate in both the creation of ozone and can retard creation of
ozone. Put another way, in isolation equilibrium concentrations of ozone, nitrogen dioxide,
and nitrogen oxide coexist. However, in the presence of organic peroxy radicals (R02),
which are foimed by the reaction of hydroxyl radicals (OH) with VOCs, nitrogen dioxide can
be regenerated from nitrogen oxide without consuming ozone, as in this reaction:
ROz + NO N02 + RO
Thus, the presence of VOCs in the atmosphere is crucial to allowing ozone to accumulate,
instead of allowing ozone to stabilize at a relatively low concentration dictated by the
equilibrium of NO and NOz. Generally speaking, the presence of more organic peroxy
radicals will allow more ozone molecules to persist in the air. The number of organic peroxy
radicals formed from a single VOC varies, and thus the photochemical reactivity of VOCs
varies.

Appendix C. Ozone and CO Nonaltainment and Air Toxic Risk Estimates
Two of the most persistent air quality problems in the United States are the
nonattainment of National Ambient Air Quality Standards for carbon monoxide (CO) and
ozone. Table C-01 lists the areas which are currently failing to meet standards for CO and
ozone.	In addition to these nonattainment problems, concern regarding the lisks
associated with motor vehicle air toxics is increasing. The cancer risks associated with the
motor vehicle pollutants of most concern are shown in Table C-02.1

Appendix G. Emission Inventories Developed Using SIP and CARB Data
As EPA began its study of nonroad emissions, one of the most comprehensive sources
of data already available were emission inventories developed for State Implementation Plans
(SIPs) EPA considered existing draft emission inventories developed by states in 1987 SIPs
and recent inventories developed by the California Air Resources Board (CARB) for their
SIPs. SIPs from eighteen geographical areas were used, as were CARB analyses for seven air
basins in California. Table G-01 provides a list of these areas.

inventories made it difficult to use inventories as available. However, the SIP inventories
considered were developed in enough detail that it was possible to discern how activity levels
for nonroad mobile sources were estimated. EPA resolved the inconsistencies where possible
and substituted new emission factors in order to generate new inventories based on the SIP
data. The emission inventories developed by CARJ3 for nonroad mobile sources were much
more detailed than those from the SIPs, and were summarized without revision by EPA.
EPA also contracted for the gathering and compiling of new, comprehensive emission
inventories in 24 cities, as described in the body of this report. The SIP inventories
categorized nonroad mobile sources in slightly different ways than EPA did in developing
new emission inventories. In Table G-02, the SIP and CARB categories are compared with
the ten equipment categories developed by EPA for this study

The following section describes in greater detail the data obtained from SIPs and the
methodology used in creating the inventories using this data.
SIP-Based Activity Levels
Emission inventories are developed as part of State Implementation Plans, or SIPs,
which are submitted periodically to EPA by areas that do not comply with NAAQS. SIPs
themselves outline means by which state authorities plan to meet the NAAQS. Generally,
this includes a plan for emission reductions, which are projected based on the baseline
emission inventory. State air quality planners generally develop emission inventones for
G-2

-------
nonattainment areas following the methodologies outlined in the existing EPA guidance.1
EPA provides information on preparing emission inventories for SIPs in a series of
five documents entitled Procedures for Emission Inventory Preparation (henceforth simply
Piocedures). The first volume gives an overview of the methodologies and reporting
requirements for emission inventories and subsequent volumes give the methodologies
whereby activity levels may be estimated at the county level for point sources,2 nonroatl and
highway mobile sources,3 and other area sources.4 Although all mobile sources are a
subcategory of area sources, the term "mobile source" was often used in past SIP emission
inventories to refer solely to highway vehicles. Emissions from all other mobile sources are,
in such cases, often reported as "off-highway mobile sources" in the area source inventory.
This is likely due to the fact that highway vehicles are already regulated and therefore much
better characterized than nonroad mobile sources. Also, nonroad mobile source activity is
often more similar to that of other area sources than is highway vehicle activity For
example, construction equipment activity can be characterized by considering the construction
industry employment during the inventory period. Similarly, fuel consumption (e.g. heating
oil) in commercial and industrial applications may be estimated using employment statistics in
the applicable industries.
After activity levels for the various source types have been estimated, emission
factors' must be applied to calculate emissions in mass per unit time for each of the
pollutants being studied in the inventory area.
Inventories developed for SIPs are usually developed for a given base year (BY);
hence emissions are expressed in tons per year (tpy). In areas where nonattainment is a
seasonal problem, the inventories may also be temporally adjusted. In many areas, ozone
nonattainment is predominately a summertime problem; therefore, emissions of ozone
precursors are expressed in tons per summer day (tpsd). Similarly, because CO nonattainment
is usually a wintertime problem/ CO emissions are often expressed in tons per winter day
(tpwd).
f Emission factors for nonroad mobile sources ihat are currently available from EPA guidance are given in
Compilation of Air Pollutant Emission Factors, Volume II Mobile Sources, Founli Edition and Supplements, AP-42,
U.S Environmental Protection Agency, Research Triangle, Park, NC, September 1985

between 1986 and 1988: Cleveland, Oliio; New Yoik City, New York; Si. Louis, Missouri, and Sleubenville, Oluo
DRAFT - October 1991	G-3

-------
For this study, EPA has examined several of the draft SIP inventories developed by
states for the 1987 and 1988 BY. Because of the CAAA requirement that states develop
emission inventories for the 1990 BY, many of the 1987/1988 draft inventories have not been
finalized at this tune. However, because the 1990 BY inventories will not be completed in
1991, only the earlier inventories may be considered for this study, despite the fact that they
are still in draft form.
In analyzing 1987 base year emission inventories from SIPs, EPA extracted the
activity levels calculated for nonroad engines and vehicles. Because the activity levels were
separated from the emission factors, it was possible to apply the emission factors developed
as part of this study to the activity levels to develop revised emission inventories that have
benefitted from improvements to the emission factors.
In adjusting the SIP emission inventories for seasonal activity variations, EPA
determined what assumptions had been used in the original inventory and applied only those
having to do with seasonal variations. Consequently, these seasonal temporal adjustments are
different from those made in inventories that also considered day-to-day activity fluctuations
or daily temporal adjustments.
Summaries of the analysis of SIP emission inventories are given in the following
tables. Detailed results of the SIP emission inventories are given in State Estimates of
Nonroad Engine and Vehicle Emissions,3 which documents for each nonattainment area
studied the nonroad engine and vehicle activity levels derived, the emissions calculated, and
the emissions from other sources (i.e., highway vehicles, other area and point sources)
Emission inventories prepared by the CARB are considered separately because
inventories for some nonroad mobile source categories have recently been developed by
CARB in support of California's proposed regulations applicable to such sources. These
emission inventories are generally more refined than those that have been developed by states
following the existing EPA guidance. Furthennore, they use different nonroad mobile souice
categories and are, therefore, not directly comparable to the draft SIP inventories.
Because of these differences from the SIP-based inventories, data from California's
nonroad mobile source emission inventories were used as provided and compared to the
highway and other source emissions given in the March 1990 version of the 1987 emission
inventory prepared by CARB. The nonroad mobile source categories for which CARB has

Appendix I. Emission Factor Development
This appendix details the origins of the emission factors used to calculate emission
inventories for this study.
For this study, emissions from internal combustion engines are broadly grouped into
one of four source categories based on the origin of the emission: tailpipe exhaust, refueling,
evaporative, and crankcase emissions. Each of those categories is further divided by
pollutant: HC, CO, NOx, and other toxic pollutants including particulate matter, aldehydes,
SOx, benzene, and 1,3-butadiene. Since refueling and evaporative emissions are not a
function of combustion, but are a function of fuel evaporation, only hydrocarbon emissions
are considered for refueling and evaporative emissions. For each source category, pollutant,
and nonroad equipment type (including fuel type and operating cycle), an emission factor is
necessary to construct emission inventories In simple terms, the emission factor is a measure
of the rate at which a particular type of equipment emits a particular pollutant under normal
operating conditions.
The remainder of this appendix describes how tailpipe, refueling, evaporative, and
crankcase emission factors were developed. Adjustments were made to new engine emission
factors to account for in-use effects and test cycle (steady state vs. transient) effects where
appropriate. These adjustments are discussed in Chapter 2 of this appendix. Emission factors
for particulate matter, aldehydes, and SOx which were not available from the primary data
sources described below were taken from AP-421 or from those recommended by Southwest
Research Institute (SwRI).2 Emission rates for nitrosamines, benzene, and 1,3-butadiene are
discussed in separate chapters at the end of this appendix. Gasoline vapors are discussed in
terms of the refueling and evaporative emissions. The emission factors used for calculating
the SIP inventories are presented in Table 1-01 and those used for calculating Inventories A
and B are in Table 1-02.
Tables 1-01 through 1-14 are located at the end of the appendix.

Chapter 1. Tailpipe Exhaust Emission Factors
A discussion of the development of tailpipe emission factors used in this study is
presented below for the following categories: lawn and garden equipment, agricultural
equipment, construction equipment, logging equipment, industrial equipment, light commercial
equipment, recreational marine, commercial marine vessels, recreational equipment, and
airport service equipment.
1.1. Lawn and Garden Equipment
l.l.i. Gasoline
The primary data source used in deriving the emission factors for gasoline lawn and
garden equipment was the California Air Resources Board (CARB) technical support
document (TSD) for lawn and garden equipment.3 The testing done for CARB was
performed by manufacturers, Southwest Research Institute (SwRI),4 and Heiden Associates3
for the Portable Power Equipment Manufacturers Association (PPEMA). The test results
represent the most up-to-date information available for this category which were aggregated
into emission factors.
The emission factors for calculating State Implementation Plan (SIP) emission
inventories required aggregation of the CARB data into a 4-stroke category and a 2-stroke
category The CARB data was weighted by the population horsepower hours data submitted
to EPA by the Outdoor Power Equipment Institute, the Portable Power Equipment
Manufacturers Association and by data contained in the Heiden report.6 Tables 1-03 and 1-04
show this aggregation for 4-stroke and 2-stroke equipment respectively. To be used in
computuig SIP emission inventories, it was necessary to convert the emission factors from
units of g/hp-hr to g/gallon fuel consumed. Brake specific fuel consumption (BSFC) values
shown in Tables 1-03 and 1-04 were used for the conversion. The origin of these values is
also shown in the tables. All aldehyde emission factors were derived from SAE Paper
910560, "Emission Factors for Small Utdity Engines."7
The emission factors necessary for calculating Inventories A and B also required some
aggregation, although not to the extent necessary for the SIP inventory calculation. The
1-2

derivation of these emission factors is shown in Table 1-05.
1.1.2. Diesel
Nearly all lawn and garden equipment is powered by gasoline engines. However, a
small population of rear engine riding mowers, lawn and garden tractors, and wood splitters,
chippers/stump grinders, and commercial turf equipment are powered by diesel engines
Since no emission data is available for diesel-powered lawn and garden equipment, the
emission factors for diesel light commercial equipment (<50 hp) were assumed to be the best
approximation and were used for the study (see "1 5. Light Commercial Equipment <50 HP").
1.2. Agricultural Equipment & Construction Equipment
1.2.1. Diesel
The most recent, up-to-date published emission factors for agricultural and
construction diesel equipment are reported in the CAL/ERT report,8 and in a recent leport to
CARB by Energy and Environmental Analysis (EEA)9 on heavy duty construction
equipment. In general, the emissions for the CAL/ERT report were measured on a 13-inode
steady-state cycle and emission factors are reported in terms of equipment types. The EEA
report presented general emission factors for HC, NO, and particulate matter by model year.
In addition to these two sources, the Engine Manufacturers Association (EMA)
submitted to EPA a list of recommended emission factors for diesel construction and
agricultural equipment presented in Table 1-06. The emission data was based on individual
engine manufacturer submissions of emission data obtained from the 8-Mode Emission Test
Procedure (ISO 8178) and related mode weighing factors. The emission factors were EMA's
best estimates of in-the-field fleet population weighted factors. For agricultural equipment,
EMA provided factors for only three equipment types (i.e. farm tractors, grain combine, and
cotton pickers).
In general, the emission factors reported by the three sources are reasonably sunilar
For agricultural equipment, EPA has selected the factors presented in the CAL/ERT study
since they are presented by specific equipment type. For the SIP inventories, the emission
factors were aggregated to tractor and nontractor categories by the energy outputs reported in
DRAFT - October 1991
1-3
-------
the CALVERT report. The factors were converted from units of g/hp-hr to lb/1000 gallons of
fuel consumed by using a BSFC of 0.4 lb/Hp-hr10 and diesel fuel density of 7.1 lb/gallon."
Table 1-08 shows the aggregation of the emission factors in terms of g/hp-hr, while Table I-
08 shows the lb/1000 gal derivation.
For construction equipment the EMA emission factors were selected to be used to
calculate emission inventories. For some equipment types, EMA factors were not available.
In these cases, the Fourth Edition of AP-4212 factors which were derived from CAL/ERT13
factors were used. Table 1-9 compares the AP-42 (CAL/ERT) and EMA emission factors for
construction equipment
The EMA did not report emission factors for particulate matter. The particulate matter
and aldehyde emission factors selected were those reported in the Fourth edition of AP-42 for
the agricultural and construction equipment categories.
1.2.2. Gasoline
The emission factors for gasoline agricultural and construction equipment selected to
be used in calculating emission inventories are from the Tliird Edition of AP-42. The other
sources that reported emission factors for diesel equipment did not report gasoline equipment
emission factors. The CAL/ERT report did suggest using 2.8 g/hp-hr HC, 163 g/hp-hr CO,
and 7.8 g/hp-hr NOx for gasoline powered equipment (Tables I-7(c) and I-8(c)). However,
the emission factors in AP-42 are more specific to equipment type and wdl be used for the
study.
The particulate emission factors in AP-42 were derived from particulate measurements
on gasoline nonroad engines at SwRI in the mid-seventies.14 Leaded gasolines which
generally contained between 1.5 and 2 grams of lead per gallon were used for the emission
tests. This high lead fuel is not commercially available today. Even today's leaded fuel
contains very little lead. Since particles consisting of lead oxides are the mam particulate
emission from leaded-gasoline fueled engines, the AP-42 emission factors are not
representative of emission rates from equipment operating on currently available gasoline
Therefore, the values reported in AP-42 were not used in this study. Instead, a value of I 64
lb/1000 gallons was used for the particulate emission factors for gasoline fueled equipment.
This value ts based on a recommendation from SwRI in the Nonroad Emission Factors of An

Toxics13 report to EPA. Where necessary, the 1.64 lb/1000 gallon was converted to 0.06
g/hp-hr by assuming BSFC 0.5 lb/hp-hr16 and density of gasoline of 6.2 lb/gallon.17
Aldehyde emission factors were taken from AP-42.
1.3.	Logging Equipment
1.3.1.	Chain Saws >4 HP
The emission factors for commercial chain saws reported in the CARB TSD18 are
used for this category.
1.3.2.	Shredders >5 HP
The emission factors reported in the CARB TSD for four-stroke commercial
sliredders/grinders are used for this category.
1.3.3 Skidders and Feller/Bunchers
The diesel emission factors for log skidders submitted to EPA by EMA (Table N-6)
are used for these categories
1.4.	Industrial Equipment
Emission factors for gasoline and diesel industrial equipment used for the study are
those reported in Volume I of AP-42. These factors were derived by SwRJ in 1973'9 and
were based on tests performed on eight diesel engines and four gasoline engines. No
emissions data were available for LPG-powered aerial lifts, forklifts, and sweepers/scrubbers
The only emission data found for LPG-powered equipment is from two gasoline engines
which were converted to operate on LPG. One engine was a 4.5 hp overhead valve walk
behind mower engine tested by Southwest Research Institute.20 Compared to the emissions
when the engine was operated on gasoline, the engine emitted 38% less HC, 55% less CO,
147% more NO,, 13% less PM, and approximately the same level of aldehydes when
operated on LPG. The other engine was a 12.5 hp utility engine tested by Onan21
Compared to operation on gasoline, tills engine emitted 72% less HC, 80% less CO, and
DRAFT - October 1991

-------
347% more NO„ when operated on LPG. Since neither of these engines are representative of
the larger industrial equipment engines, the emission data cannot directly be used for
developing an emission factor. However, the relative differences between the gasoline and
LPG emission results for the two engines can be used to approximate the LPG emission
factor. The above percentages were averaged resulting in a 55% reduction in HC, a 68%
reduction in CO, a 247% increase in NO,, and a 13% reduction in particulate matter
compared to the gasoline baseline emission values when an engine is operated on propane.
These percentages were applied to the gasoline emission factors to approximate the LPG
emission factors.
1.5.	Light Commercial Equipment <50 HP
Light commercial equipment includes generator sets, pumps, air compressors, gas
compressors, welders and pressure washers The emission factors recommended by SwRl22
for the continuous service diesel equipment will be used for the study. These factois aie the
refrigeration unit emission factors in the Radian report23 Emission factors for gasoline light
commercial equipment to be used in die study are taken from the CARB teclinical support
document for utility and lawn and garden equipment24 for large engines. Engines tested to
develop the large engine emission factors included a 16 hp single cylinder side valve engine
and two 18 hp 2-cylinder side valve engines. No emissions data were available for LPG
powered pumps and gas compressors. Therefore, the gasoline emission factors for these
equipment types were decreased by 55% for HC, decreased by 68% for CO, increased by
247% for NOx, and decreased by 13% for particulate matter to approximate the LPG
emission factors. This methodology is discussed in "1.4. Industrial Equipment" above.
1.6.	Recreational Marine
1.6.1. Outboard Motors
The emission factors for outboard motors used in the study are from AP-42 which
were derived from testing performed at Southwest Research Institute in 1973.23 The
1-6
DRAFT - October 1991
-------
emission factors presented in AP-42 are the exhaust emissions less the emissions retained in
the water, since most outboards have underwater exhausts. Although the environmental
impact of outboard exhaust on water quality is not completely understood, the current
International Counsel of Marine Industry Associations (ICOMIA) emission measurement
standards are based on total exhaust; not accounting for water scrubbing. Therefore, for the
purposes of this inventory study, EPA believes that outboard exhaust should be inventoried as
total exhaust emissions before water scrubbing. The emission factors in AP-42 were
recalculated to include both atmospheric and water phase emissions.
The National Marine Manufacturers Association submitted emission measurement
data26 from production engines tested using the ICOMIA standards. The emission results are
presented as brake specific (g/kW hr) emissions versus engine power (kW) in graphical form.
Also shown on the graphs are curves of the least squares fit. The HC, CO, and NOx
emission factors derived from the SwRI data, in general, were lower than those submitted by
NMMA.
1.6.2.	Inboard Gasoline
The emission factors used in the study for gasoline-fueled inboard engines are from
AP-42. These factors were developed from tests of automotive engines and are considered
only rough estimates. As with outboard engines, the emission factors were adjusted to
represent total engine emissions. NMMA also has submitted emission measurements
performed by member manufacturers.
1.6.3.	Inboard Diesel
Few measurements have been performed on high speed diesel marine engines. The
best currently available published estimates appear to be those from the Radian study27
which are used for this study.
1.7. Commercial Marine Vessels
The AP-42 guidance document subdivides commercial motorships mto waterway
classifications for the purpose of calculating SIP emission inventories. The classifications are:
coastal, great lakes, and river. The vessels operating in each of these waterways have similar
DRAFT - October 1991
1-7
-------
characteristics such as size, speed, engine design, and distance traveled. Emission factors for
these classifications are contained in AP-42. These factors are used by states for calculating
emission inventories by the fuel sales method described in the Procedures for Emission
Inventory Preparation, Volume IV• Mobile Sources28 guidance document published by EPA.
Another set of emission factors for calculating emission inventories using a different method
(the ship movement data method) is contained in the guidance document. The factors are in
terms of size categories (draft). The emission factors used for the SIP inventory calculations
will be those reported in AP-42 and the guidance document with the exception of the slow
speed diesel emission factors For slow speed diesel marine engines, the emission factors
reported in a recent Booz Allen & Hamilton study29 for CARB will be used. This source is
thought to better represent actual NOx emission factors for the reasons set forth in the report
Emission factors for medium speed diesels were also reported by Radian10 to CARB in
1988. These factors were based on tests of locomotive engines. The NOx emission factor
reported by Radian is 533 lb/1000 gal which is substantially higher than the factors reported
in AP-42 (approx. 300 lb/1000 gal)
1.8. Recreational Equipment
1.8.1. Off-Road Motorcycles
As part of a recent CARB proposal to control emissions from off-road motorcycles,31
CARB calculated emission factors for two-stroke and four-stroke engines. The factors are
shown in Table I-10. To calculate SIP inventories, these factors were aggregated into
composite factors by using a 68.5% two-stoke, 31.5% four-stroke distribution provided by
EEA The two-stroke and four-stroke emission factors for off-road motorcycles were also
assumed for all terrain vehicles, minibikes, golf carts, and specialty vehicle carts
-1.8.2. Snowmobiles
Very little data exists on emission rates from snowmobiles. The best currently
available published data appears to be contained in AP-42. These emission factors were
derived from testing performed by SwRI in 197432 and are being considered for the study
The factors in terms of g/hr were converted to g/hp-hr for use in calculating emissions

DRAFT - October 1991
-------
inventories from the activity information provided by EEA. The power reported by SwRI for
the various test engines was weighted in the same manner as the emission values to determine
a composite power of 5 8 hp over die test cycle. The g/hr value was then divided by 5.8 to
determine g/hp hr. In a recent response to CARB mail out #90-70 entitled A Proposal to
Establish Exhaust Emission Standards and Test Procedures for Off-Highway Light-Duty
Vehicles and Recreational Vehicles, the International Snowmobile Industry Association (ISLA)
reported snowmobile emission factors of 216 g/hp-hr HC+NOx, and 564 g/hp-lir for CO
These factors are substantially higher than those calculated from the AP-42 factors even
though the same SwRI test procedures were used in both cases.
1.9. Airport Service Equipment
The emission factors for industrial equipment were assumed to apply to airport service
equipment.

Chapter 2. Adjustments to Tailpipe Emission Factors
2.1. Adjustments for Test Cycle
To develop emission factors representative of in-use nonroad engines, the test cycle
that the engines are operated on should simulate typical in-use operation. There is much
debate regarding the appropriateness of using a steady-state test cycle or a transient test cycle
for emission testing nonroad engines. A steady-state test is a series of fixed set points of
speed and load held for a period of time (usually from two to ten minutes). Emission
measurements are made at the end of the period when readings have stabilized. Currently, a
transient cycle is used to certify heavy-duty highway engines It is a continuously varying
cycle of speeds and loads which may have brief periods of steady-state operation. Emission
measurements are made continuously over all points.
The emission factors submitted by EMA for nonroad equipment were based on data
generated using a standardized 8-mode steady-state test cycle. The 8-mode test cycle does
not measure emissions during transition and stabilization between modes. This could
understate the emissions of equipment that encounters transient operation in use. This is
especially true for particulate emissions, which the 8-mode cycle does not provide a good
measurement for equipment that encounters transient operation. On the other hand, the
highway heavy-duty transient cycle may not be appropriate to simulate nonroad equipment
transient operation. EPA expects that emission levels of nonroad equipment that encounters
transient operation in use will fall somewhere between levels during a steady state test such
as the 8-mode and the highway transient test.
For diesel powered equipment expected to encounter either transient speed or transient
load conditions in-use, EPA adjusted the emission factors that were generated using a steady-
state cycle Data from a joint EPA/Industry program to assess test cycles for nonroad
equipment was used to determine the ratio of the FTP transient test emissions to the 8-mode
steady-state test emissions. Based on the currently available data (four engines) these ratios
were: 1 3 foi HC, 2 0 for CO, 1 for NOx, and 1.7 for particulates. These ratios were then
applied to the emission factors of the appropriate equipment types to determine the adjusted
emission factors in Table I-2a.
1-10
DRAFT - October 1991
-------
2.2. Adjustments for In-Use Operation
The emission factors contained in Tables I-02a, I-02b, and I-02d were developed using
data from testing new engines. Although many of the test procedures used for emission
testing required an engine break-in period, the tests performed on new engines do not account
for in-use impacts on emissions from engine malfunctions, improper maintenance, and engine
wear. To assess the magnitude of these impacts, EPA contracted with Southwest Research
Institute (SwRI) to emission test small in-use utility engines. EPA also used existing data on
pre-controlled heavy duty engines to estimate in-use impacts on emission factors.
Southwest Research Institute procured five in-use utility engines (3 four-stroke engines
and 2 two-stroke engines) and performed emission tests using the SAE J1088 procedure. A
description of the engines and the emission test results are shown in Table 1-11. The table
also shows the emission factors used for the respective equipment types which were derived
from new, properly operating engines. The ratio of the in-use engine test emissions to the
new engine emission factor is also shown in the table and these values were averaged to
determine an in-use adjustment factor which can be applied to new engine emission factors
2.2.1.	Four-Stroke Gasoline Engines Under 20 HP
The four-stroke engines tested by SwRI showed twice the HC and CO emissions, 0.4
times the NOx emissions, and 3.6 times the particulate emissions of new engine emissions
(Table I-11). These engines exhibited problems of low power, head gasket leaks and others
which are described in the SwRI report.33 Although only a very small sample of 4-stroke
engines were tested, the trend of high HC, CO, and particulates and low NOx was consistent.
Thus, the adjustment factors were applied to the emission factors of gasoline 4-stroke engines
less than 20 hp. The resulting emission factors (Table I-2c) represent a rough approximation
of in-use nonroad engine emission levels
2.2.2.	Four-Stroke Gasoline Engines Over 20 HP
In 1983, the Engine Manufacturers Association (EMA) and the EPA conducted a joint

gasoline engines. The program used 1979 and 1982 model year pre-controlled engines and is

the best available source of data for representing in-use noiiroad engine emissions. Using this
data, a linear regression analysis was performed and the emissions as a function of mileage
was plotted. To estimate the in-use adjustment factors some broad assumptions were made.
Typical in-use engines were assumed to be have accumulated 55,000 miles, which is half of
the useful life of 110,000 miles defined in the regulations for heavy-duty gasoline enguies14
The regression analysis was then used to calculate an in-use factor by dividing the emission
value at 55,000 miles by that at 0 miles. The resulting factors of 1.5 for HC and 1.3 for CO
were applied to the emission factors of gasoline 4-stroke engines over 20 hp to approximate
in-use emission factors (Table I-2c). The NO, emissions showed no significant change with
mileage accumulation and therefore NO„ emission factors were not adjusted. Particulate four-
stroke engine emission factors were not adjusted since no data was available.
2.23. Two-Stroke Gasoline Engines
As discussed above, SwRI tested 2 two-stroke in-use engines. One was from a walk
behind mower (WBM) application and the other was from a string trimmer application. The
eleven year old WBM engine exhibited HC, CO, and PM emissions similar to the new engine
emission factors shown in Table 1-11. This engine produced somewhat higher NOx emission
than the new engine factors show. The string trimmer engine, on the other hand, showed
extremely high HC, CO, and PM levels and similar NO, levels compared to the new engine
emission factors. Since only two data points were avadable for two-stroke engines anil these
data were widely divergent, EPA did not estimate in-use adjustment factors based on these
points. Instead, the factors used for four-stroke engines less than 20 hp were used for HC
and CO emissions, as the two-stroke data bracketed the four-stroke results for these pollutants
(i e., one data point was much lower and one was much higher). The four-stroke NO„
adjustment factor of 0.4 did not seem appropriate to apply to two-strokes since both the two-
stroke engines tested by SwRI showed nearly equal or higher emission levels than new engine
emission factors. Therefore, no adjustment was made to NOx new engine emission factors.
Also, the four-stroke particulate adjustment factor of 3 6 did not seem appropriate since the
new engine emission factor used as numerator of the factor ratio was very small compared to
the new emission factor value for two-stroke engines. Therefore, no adjustment was made to
the two-stroke PM new engine emission factor.

As discussed earlier, EMA and EPA conducted a joint program to assess the emission
factors of pre-controiled heavy duty diesel and gasoline engines. For diesel engines, the data
showed no increase in HC, NOx, or PM with vehicle mileage. Therefore, the new engine
diesel emission factors were not adjusted for in-use effects.

Chapter 3. Refueling and Evaporative Emission Factors
Hydrocarbon (HC) refueling and evaporative emission factors are presented in this
section. A list of nonroad equipment and their evaporative and refueling emission factors
may be found in Tables 1-01, 1-02, 1-12 and 1-13. Table 1-12 and 1-13 are also good
summaries of how refueling and evaporative emission factors were calculated for gasoline and
diesel fueled equipment, respectively.
This section on refueling and evaporative emission factors is divided into four sub-
sections that (1) introduce the concept of refueling and evaporative emissions, (2) present the
fuel tank volume values used in calculating refueling and evaporative emission factors, (3)
present the methodology and data (except fuel tank volumes) used to calculate refueling
emission factors, and (4) present the methodology and data (except fuel tank volumes) used to
calculate evaporative emission factors. Fuel tank volumes are discussed separately to avoid
duplication of discussion in the sections on refueling and evaporative emission factor
methodology and data.
3.1. The Concepts of Refueling and Evaporative Emissions
The concepts of refueling and evaporative emissions are presented in this sub-section
and are applicable to both gasoline and diesel fueled equipment although, perhaps more
pertinent to gasoline fueled equipment than diesel fueled equipment.
3.1.1. Refueling Emissions
There are two components of refueling emissions: spillage and vapor displacement.
Spillage emissions, or simply spillage, are those emissions resulting from spilled fuel incurred
during the refueling process. For example, spillage includes those vapors generated from fuel
spilled while filling a storage container from a gas station pump and vapors generated from
fuel spilled while transferring the fuel from the container to the equipment Vapor
displacement emissions, or displacement, are those emissions that result from displacing fuel
vapors in the fuel tank with liquid fuel. For example, if one gallon of gasoline is poured into
a container which already contains some gasoline, one gallon of fuel vapor is displaced to the
1-14
DRAFT - October 1991
-------
atmosphere by the incoming fuel. For the purposes of this study, only fuel lost while
refueling the equipment is considered. One would expect, however, that displacement
emissions resulting from the refueling of storage containers would be on the same order of
magnitude as the displacement emissions from equipment.
3.1.2. Evaporative Emissions
Evaporative emissions are losses due to evaporation of unburned fuel. Evaporative
emissions do not pass through the combustion chamber but, rather, the primary sources of
evaporative emissions are the carburetor and fuel tank. Similar to their on-road counterparts,
evaporative emissions from nonroad sources can be subdivided into four groups: hot soak,
diurnal, running loss, and resting loss emissions. Each category accounts for emissions
during specific operating conditions of the equipment and various mechanisms of emission
Hot soak emissions are those emissions which occur after the equipment has been turned off
and are attributable to the elevated temperature of the equipment (e.g., evaporation from the
carburetor bowl). Diurnal losses are those vapor emissions which occur while the equipment
is not operating and are attributable to natural changes in ambient conditions (temperature,
pressure, etc). Running loss emissions are those emissions wliich do not pass tlirough the
combustion chamber while the source is in operation. Resting loss emissions are those
emissions which occur that are not already identified by another category. For example,
emissions which are due to permeation of fuel through fuel lines and fuel tank, and leakage in
the fuel system are resting-loss emissions. For the purposes of this study, only diumal
emissions will be considered due to the lack of data for hot-soak, resting loss and running
loss emissions.
3.2. Developing Effective Fuel Tank Volumes
This sub-section will present those data and assumptions which were used to airive at
effective fuel tank volumes for specific gasoline and diesel equipment. Fuel tank volumes are
not discussed along side the presentation of other data because both evaporative and refueling
emission factors use fuel tank volumes as part of their calculation. A separate discussion of
fuel tanks will avoid tedious duplication of discussion later
DRAFT - October 1991
I-15
-------
This sub-section on developing effective fuel tank volumes is divided into two sections.
The first section presents effective fuel tank volumes for gasoline equipment and the second
section presents effective fuel tank volumes for diesel equipment.
3.2.1. Gasoline Fuel Tank Volumes
Data used to calculate gasoline fuel tank volumes may be broadly categorized into two
groups, data supplied by manufacturers and manufacturers' sales brochures, and data
generated by EPA. Effective fuel tank volumes generated from each of these sources is
discussed below
Manufacturers' Fuel Tank Data — Manufacturers were asked to supply fuel tank
volumes for several pieces of equipment. When data supplied by manufacturers matched an
equipment category exactly, the data was used directly However, the fuel tank volumes
provided often did not quite match the equipment categories used by EPA in this study anil
aggregation was required. When possible, a weighted average of the fuel tank volumes was
used to generate an effective fuel tank volume.
Effective fuel tank volumes are not necessarily constant for a particular equipment
type A weighing factor may be important when finding an average fuel tank volume to be
used to calculate diurnal emissions but, that same weighing factor may not be important when
calculating refueling emissions, or vice-versa. Diurnal emissions are influenced by the
population and the length of season (assuming the equipment is used every few days).
Refueling emissions are influenced by amount of fuel consumed which is a function of
population, horsepower, load factor, brake specific fuel consumption and usage rate.
Therefore, the purpose for which the average fuel tank volume is calculated dictates how
individual fuel tank volumes are weighted.
For instance, walk behind lawnmowers have a range of fuel tank volumes of 0.37 to
0 68 gallons. It is known that the smaller fuel tank volumes tend to be used by consumers
while equipment with larger tanks tend to be used commercially. Furthermore, although there
may be fewer commercial lawnmowers, their usage rate is much higher and their season
length is probably longer. When calculating the diurnal emission factors, the effective fuel
tank volume should account for these factors. Other weighing factors are used when
1-16
DRAFT - October 1991
-------
calculating an effective fuel tank volume for refueling emission factors.
Unfortunately, calculated effective fuel tank volumes are the same for refueling and
evaporative emission factor development because so many of the weighing factors were not
available. The weighings were often reduced to mere population weighings or averages (i.e.,
if a particular weighing factor is not known, then the category is assumed to be homogeneous
with respect to that weighing factor). As a result, the fuel tank volumes used for calculation
of evaporative emissions are the same as those used for refueling emission factors unless
specifically indicated.
The discussion below presents effective fuel tank volumes for each equipment type
where fuel tank volume data was available from the manufacturer but not in direct usable
form. Fuel tank weighings for calculation of gasoline refueling emission factors are discussed
first and fuel tank weighings used in calculating gasoline evaporative emission factors are
discussed afterwards where different from those presented for refueling emission factors As
mentioned earlier, Tables 1-12 and 1-13 are good summary sheets of the calculations discussed
below.
Gasoline Fuel Tank Volumes for Calculation of Refueling Emission Factors ~ Ideally,
effective fuel tank volumes for generation of refueling emission factors are weighted by the
amount of fuel consumed which is a function of population, horsepower, load factor, brake
specific fuel consumption, and usage rate. As will be seen, tank volumes are very seldom
weighted ideally.

Effective fuel tank volumes used for evaporative emission factor development which are
different from those as shown for refueling emission factor development are listed below.
Ideally, when aggregating equipment fuel tank volumes for evaporative (diurnal only)
emission factor generation, the values would be weighted by population and days of in-use
season. However, days of in-use season are not available and, therefore, could not be used

3.2.2. EPA Generated Fuel Tank Volumes
For most equipment types, the fuel tank volume data are estimates based on
engineering judgement from industry representatives or values found in sales brochures.
Several fuel tank volumes, however, were not provided by industry and alternative methods of
approximating the fuel tank volumes were necessary.
Three alternatives were identified to approximate missing fuel tank volume data. The
first alternative is to substitute fuel tank values from equipment that use similar engines. For
example, the fuel tank volume for Generator Sers is also used for Signal Boards because
signal boards use generators. If a substitution is not possible or justifiable then, the second
alternative is to calculate fuel tank volumes based on regression analysis. A regression of
known tank volumes versus net engine horsepowers was created by EPA and is described in
detail later in this sub-section. The third alternative is the use of fuel tank volumes based on
the engineering judgement of EPA personnel which have also been accepted by industry
representatives. For all equipment, manufacturer suggested values were used if available and
if not, then the first, second and third alternatives were used, respectively.
Volumes Based on Equipment with Similar Engines — Fuel tank volumes which were
assumed based on the known values of equipment that use similar engines are shown below.
The names of equipment categories included in this study are italicized distinguish them from
equipment types used by manufacturers in communicating data to EPA.
Woodsplitter - assume equivalent to Lawnmowers (0.57 gal).
Commercial Turf Equipment - Wide area walk behind lawnmowers comprise the majority
of this category and therefore, the wide area walk behind lawnmower spillage value is used
(5.0 gal). Hydro-seeders/mulchers, although a part of this category, were not incorporated
into this number due to unknown weighing factors and relatively insignificant populations
Other Lawn and Garden Equipment - assume equivalent to Lawnmowers (0 57 gal)
Specialty Vehicles Carts - assume equivalent to Golf Carts (6 gal).
Air Compressors - assume equivalent to small compressors (1.13 gal).
Pressure Washers - assume equivalent to Pumps (0 75 gal)
Tampers/Rammers - assume equivalent to Plate Compactors (0.94 gal).
DRAFT - October 1991	1.21
-------
Paving Equipment - assume equivalent to vibrators/finishers (1 0 gal). Note that this is a
good assumption for the gasoline portion of paving equipment only
Signal Boards - assume equivalent to Generator Sets (1.0 gal).
2-Wheel Tractors - assume equivalent to Lawn and Gat den Tractors (2.45 gal).
Agricultural Mowers - assume equivalent to Lawn and Garden Tractors (2.45 gal)
Sprayers - assume equivalent to crop/turf sprayers (1.5 gal). Fertilizer spreaders were not
included in this category because there is not adequate means to weigh their impact.
Volumes based on Regression Line — A regression of fuel tank volume versus net
engine horsepower from John Deere farm, construction and utility engines was created by
EPA from John Deere product literature. The regression line is only applicable to those
equipment with engines of 15 Hp or more.43 The result of that regression is:
Fuel Tank Vol =0.51 x Net HP ; R2 = 0.82
Articulated tractors and feller-bunchers were excluded from the regression due to their
exceptionally high fuel tank volumes. A list of equipment type, model, engine, net hp and
fuel tank volume for all equipment used in that regression as well as a plot of the data is
presented in Table 1-14.
As indicated in Table 1-14, most of the equipment used to create the above regression
line are diesel fueled. There may be some concern that fuel tank volumes of similar diesel
and gasoline equipment do not approximate each other because a particular piece of gasoline
equipment tends to be smaller and have a smaller fuel tank than its diesel counterpart. This
should not be the case when comparing gasoline and diesel equipment of similar horsepower
Diesel equipment tend to have larger fuel tanks because they tend to have larger engines.
When the influence of the size of engine is removed, as done by the regression, that
difference should be minimal. On the contrary, a larger mass of gasoline is required to do the
same amount of work as done by a diesel fueled piece of equipment (i.e., the brake specific
fuel consumption of gasoline equipment tends to be higher) and, therefore, gasoline fuel tanks
would necessarily be larger to accommodate the same amount of work. Thus, use of this
1-22

regression may slightly overestimate gasoline spillage emissions but, underestimate gasoline
diurnal emissions.
Due to the lack of similarity of much of the equipment, the regression line was used
extensively. The gasoline equipment for which fuel tank volumes were calculated from the

assumptions regarding the fuel tank size of "Sailboat Auxiliary Inboard Engines" (6 gal ),
"Sailboat Auxiliary Outboard Engines" (6 gal.) and Vessels w/Sterndrive Engines" (21 gal )
because data for those categories was not available. These values were presented to the
National Marine Manufacturers Association (NMMA) and deemed to be acceptable estimates
based on available data.44
Diesel Fuel Tank Volumes ~ Fuel tank volumes for most diesel equipment were

3.3. Methodology Used to Calculate Refueling Emission Factors
This section will present the methodology and data used to calculate refueling
emission factors. Refueling emissions are composed of spillage and displacement emissions
and tliis section will present each individually for both gasoline and diesel equipment.
3.3.1. Gasoline Refueling Emission Factors
Spillage -- Very little work has been done to quantify the amount of fuel spilled while
refueling nonroad engines. The only known spillage values have been presented by Briggs &
Stratton and OPEI for lawn and garden equipment (primarily standard walk behind
lawnmowers). Briggs & Stratton has presented a value of 45 grams (approximately 1 5 oz.)
per refueling and suggested that the value be reduced to 22.5 g/refueling as the user becomes
familiar with the equipment.43 OPEI reported in a study completed in September of 1991
that 17 grams of fuel were spilled during a typical refueling incident All of these values are
much higher than the spillage value which may be backed out of Mobile4 for on-highway
vehicles which is roughly 3.6 g/refueling (0.31 g/gal * 11 5 gal/refuel).46
The discrepancy between the Mobile4 value and the OPEI and Briggs & Stratton value
is most likely due to the fact that (1) many nonroad engines are refueled from fuel containers
which are more difficult to use than gasoline pumps, (2) fuel containers do not have
automatic shut off capability and (3) equipment fuel tanks are not as accessible. Therefore,
the numbers provided by OPEI and Briggs & Stratton are probably closer to the true value for
nonroad engines which are typically refueled from a portable, hand-held fuel container.
When deriving the emission factors presented in this study, EPA has assumed that 17 g of
fuel is spilled per refueling when a portable fuel container is used and, for nonroad equipment
that is refueled from a gasoline pump, spillage is assumed to be 3.6 g/refueling. EPA chose
the OPEI over the Briggs & Stratton value because it is based on substantially more data
The method of refueling (pump or container) is discerned by application and fuel tank
size. Lawn and garden (except chippers/stump grinders), recreational, and light commercial
equipment are assumed to be refueled from portable fuel containers In addition, any other
equipment with fuel tank volumes less than 6 gallons47 are assumed to be refueled piimaiily
from portable fuel containers regardless of category (except baggage tow tractors) All other

equipment are assumed to be refueled from a fuel pump. In either case, the amount of fuel

where Tank Vol. is the fuel tank volume. All refiielings are assumed to be fill-ups of an
empty tank and thus, these spillage estimates are conservative (low).
Vapor Displacement ~ No estimates for vapor displacement emissions from nonroad
engines can be found in literature. However, on-road and nonroad displacement values
should be similar since the gasoline composition for both is the same. Therefore, EPA lias
unplemented a model proposed by Rothman and Johnson of the EPA to predict displacement
emissions48:
Disp. = -5.909 - 0.0949 x dT + 0.0884 x Td + 0.485 x RVP
where: Disp. = Displacement —
dT - Temp of Tank - Temp of Dispensed Fuel (° F)
Td = Temp of Dispensed Fuel (° F)
RVP = Reid Vapor Pressure
Rothman and Johnson also recommend national average values for the parameters depending
on the season of year. EPA has used the Rothman and Johnson national average parameter
suggestions and matched equipment types to the national average parameters for the particular

season of the year in which the equipment is most likely to operate (refer to Table 1-12). The
equipment tank temperature, dispensed fuel temperature and delta T values suggested by
Rothman and Johnson are shown in the table below for equipment which are refueled from a
gas pump49 Rothman and Johnson's summer and annual RVP values are not used in
anticipation of the new RVP standards which limit RVP to 10.5 during the summer months
The annual average RVP was therefore recalculated based on the new summer RVP (5
months) and the winter RVP (7 months) from Rothman and Johnson The table shows that
there is relatively little overall effect on displacement emissions by season of the year

The temperature differences between die equipment's fuel tank and the dispensed fuel
(dT) as well as the actual dispensed fuel temperature (Td) shown above are representative of
fuel dispensed from underground storage tanks. It is unlikely that the temperature of fuel
dispensed from a portable fuel container will match that of fuel dispensed from an
underground storage tank. Rather, the fuel temperature from a portable container will most
likely match that of the fuel in the equipment since both the container and equipment are
exposed to the same ambient conditions. Therefore, the values suggested by Rotlunan and
Johnson as shown above are used only for equipment refueled from gasoline pumps For
equipment refueled from fuel containers, the values are identical except that dT is assumed
1-26
DRAFT - October 1991
-------
equal to zero and Td (the temperature of the dispensed fuel) is assumed equal to the
temperature of the fuel in the tank (dT + Td).
It can be correctly argued that the dispensed fuel temperature for many nonattaiiunent
areas will be dissimilar to those values presented above—especially the winter time values.
While recognizing this deficiency, EPA is unable to incorporate city-by-city emission factors
due to the immense size of that task.
As stated earlier, lawn and garden (except chippers/stump grinders), recreational, and
light commercial equipment are assumed to be refueled from a portable gas container and
therefore have a dT value equal to zero. In addition, any other equipment (regardless of
category) with fuel tank volumes less than 6 gallons are also assumed to be refueled primarily
from fuel containers (except baggage tow tractors) and have dT equal to zero. All other
equipment are assumed to be refueled from a gasoline pump and have a dT value as shown ui
the table above. A list of various equipment and the associated displacement emission factors
as well as total refueling emission factors is located in Table 1-12.
To make the refueling emission factors compatible with the populations and usage
rates used in the study, the units were changed from grams per gallon to grams per
horsepower hour (except some recreational equipment which are expressed in g/hr). To
facilitate that change, assumptions regarding the brake specific fuel consumption (BSFC) were
necessary. BSFC data provided by SWRI and CARB were used to estimate BSFC for
equipment with average horsepower of 8 hp and less, 8 hp to 20 hp and above 20 hp. The
values assumed are 0.21930, 0.15"'", or 0.080652 gal/hp-hr, respectively Thus, refueling
emission factors were easily transformed to units of grams per brake horsepower hour. For
example, if the original spillage value is 49.78 g/gal (walk behind lawnmower; avg hp = 4.0)
then,
49 78 g/gal * 0 219 gal/hp-hr = 10.90 g/hp-hr
Refueling emission factors for all recreational equipment except snowmobiles are
expressed in units of g/hr, instead of g/hp-hr. The conversion was made by multiplying the
original value in g/hp-hr by the average horsepower and load factor supplied by EEA For
example, the conversion for minibikes is.
11.26 —x 4 hp x 0.62 = 12.92 S-
hp-hr	hr

3.3.2. Diesel Refueling Emission Factors
Refueling emissions from diesel fueled equipment are not as significant as those from
gasoline fueled equipment because diesel fuel has a relatively high initial boiling temperature
of 350 °F which impedes its evaporation. Gasoline, on the other hand, has initial boiling
temperatures of 60 - 80 °F depending on the season of year (RVP) and, therefore, evaporates
more readily.53 As a result, very little work has been done to quantify diesel refueling
emissions. Indeed, EPA is not aware of any studies of emissions from spilled diesel fuel.
However, work has been done by F Peter Hutchins of the EPA to quantify displacement
emissions from diesel fuel.34 Hutchins' work has shown the displacement emissions from
diesel fuel to be 0.041 grams per gallon of fuel dispensed for dispensed fuel and fuel tank
temperatures of approximately 80 °F. For the purposes of the present study, all diesel
equipment are assumed to emit HC vapors at a rate of 0.041 grams per gallon of fuel
dispensed. EPA is not aware of any other data pertaining to refueling or evaporative
emissions from diesel fueled equipment and, therefore, seveial emission sources are not
included in this study.
Just as was needed for the gasoline refueling emission factors, the diesel refueling
emission factors were adjusted to be compatible with the populations and usage rates used in
the study. The units were changed from grams per gallon to grams per horsepower hour
(except some recreational equipment which are expressed in g/hr). To facilitate that change,
assumptions regarding the brake specific fuel consumption (BSFC) were necessary.
Recognizing that diesel equipment generally has a higher BSFC than gasoline equipment, the
factors above were multiplied by 0.8. Therefore, the BSFCs assumed in this report for diesel
equipment are 0.175, 0.12, and 0.065 gal/hp-hr, for engines under 8 hp, between 8 and 20 hp,
and over 20 hp, respectively Refueling emission factors for all recreational equipment except
snowmobiles are expressed in units of g/hr, instead of g/hp-hr. The conversion was made by
multiplying the original value in g/hp-hr by the average horsepower and load factor supplied
by EEA.

3.4. Methodology Used to Calculate Evaporative Emission Factors
This section will present the methodology and data used to calculate evaporative
emission factors for gasoline and diesel equipment. Evaporative emissions are composed of
diumal, hot-soak, resting loss and running loss emissions and this section will present each
individually.
3.4.1. Gasoline Evaporative Emission Factors
Diurnal — The most comprehensive data available for diurnal emissions appears to be
contained in two reports written by Charles T. Hare and Karl J. Springer of Southwest
Research Institute.33-36 Both CARB and AP-42 refer to their work for diurnal emissions.
In summary, Southwest developed diumal emission factors of 2 g/gal/day37 and 4 g/gal/day
for protected (shaded) and unprotected fuel tanks, respectively, during the in-use season. This
report will assume the average of the two estimates 3 g/gal/day because of the difficulty in
determining what percentage of each type of equipment has protected or unprotected fuel
tanks. Diumal emission factors, in units of grams per day of possible use, are calculated
using the fuel tank volumes supplied by manufacturers and are presented in Table 1-12
Diumal losses occur only during those portions of the year when the equipment is used
relatively regularly (every few days).38 In other words, if the equipment is not used
regularly, then diumal emissions become negligible.
Hot-Soak — After reviewing SAE papers and SwRI reports regarding evaporative
emissions and referring with several manufacturers, EPA found no appiopriate values foi hot-
soak emission factors for off-road engines. Hot-soak emission values for on-highway engines
do exist, but they are not representative of off-road engines due to the different size, design,
packaging and carburetors that each employs. Therefore, this study does not account for hot-
soak emissions.
Resting Loss ~ Resting loss emissions are not included in this study due to the lack
of available data. However, to obtain a feel for the potential magnitude of this type of
emission, one can consider die amount of fuel a plastic storage container is permitted to lose
and still meet the standards devised by the American Society for Testing and Materials
(ASTM). A non-metallic fuel container passes the standards set by ASTM if it loses less
than 1% of its mass over 30 days at a temperature of 75 °F. The test fuel used is a 70%

-------
isooctane, 30% toluene mixture (by volume). Assuming that the test fuel and regular
gasoline behave the same, the standard indicates the fuel container could loose up to 28
grams of fuel per month.
Running Loss ~ Just as for hot-soak emissions, no data on the subject of running loss
emissions for nonroad engines was found and on-highway values would not be representative
Therefore, running loss emissions are not accounted for in this study.
3.4.2. Diesel Evaporative Emission Factors
EPA is not aware of any diesel evaporative emission data and therefore, diesel
evaporative emissions are not included in this study. On a qualitative basis, however, it can
be said that evaporative emissions from diesel equipment should be much less than
evaporative emissions from gasoline equipment because diesel fuel has a relatively high initial
boiling temperature of 350 °F which impedes its evaporation. Gasoline, on the other hand,
has initial boiling temperatures of 60 - 80 °F depending on the season of year (RVP) and,
therefore, evaporates more readily 39

Chapter 4. Crankcase Emission Factors
Crankcase emission factors are presented in this section for gasoline and diesel
nonroad equipment after a brief introduction of crankcase emissions.
Crankcase emissions are those exhaust gases which, upon leaving the combustion
chamber, do not pass through the exhaust valve. Rather, the gases discharge into the
crankcase via the clearance between the piston and cylinder wall. Eventually, these gases
may escape from the crankcase to the atmosphere, hence, they are named crankcase emissions
and the crankcase is said to be open. Some manufacturers produce crarikcases which route
vapors to the air intake system of the equipment. Those crankcases are called closed
crankcases. Crankcase emissions, together with evaporative, refueling, and tailpipe emissions,
constitute the total emissions from an engine
The rest of this section is separated into two parts. The first part introduces crankcase
emission factors for 4-stroke gasoline fueled engines and the second introduces crankcase
emission factors for 4-stroke diesel fueled engines Several documents have been referenced
and the best available emission factors have been identified for use in the nonroad study/'"
4.1. Gasoline Crankcase Emission Factors
This section will present crankcase emission factors for nonroad gasoline engines and
describe the methodology for developing them.
r
Crankcase emission data for nonroad engines do not exist. For hydrocarbon (HC)
nonroad crankcase emission factors, estimates are based on on-highway data. No emission
estimates for crankcase carbon monoxide (CO) or oxides of nitrogen (NOx) are available and
therefore, those pollutants are not considered for gasoline nonroad crankcase emissions. The
following paragraphs will present crankcase HC emission factors for gasoline nonroad
engines.
Probably the most widely accepted values for nonroad crankcase HC emissions are
those found in AP-42.61 AP-42 reports crankcase HC emissions for farm and constiuction
equipment based on work performed by Southwest Research Institute (SwRI) in the eaily
1970's.r,z The SwRI work on crankcase HC emissions suggests that "ciankcase hydiocarbon

-------
emissions are equivalent to about 20 percent of those in the exhaust . . ."63 This
generalization is based on work performed by Charles M. Heinen64 and P. A. Bennett, et
al65 on on-highwav vehicles. However, when calculating crankcase emissions, Hare and
Springer misinterpreted the Heinen and Bennett reports. Bennett estimated crankcase
emissions to be approximately 70% of exhaust emissions (40% of total HC emissions) based
on testing five cars.66 Heinen, on the other hand, chose the value of 33% of exhaust
emissions (20% of total HC emissions) which was estimated by Fred W. Bowditch of General
Motors.67 Heinen chose Bowditch's number as the best compromise of competing values
supplied by CARB (31% of uncontrolled HC exhaust; 20% of total).68 the Federal
Government (49% of uncontrolled HC exhaust; 26% of total)69 and Bowditch (see chart
below). The origins of the values supplied by the Federal Government and CARB are
unknown while the crankcase emission values put forth by Mr. Bowditch (33% of
uncontrolled HC exhaust emissions and 20% of total emissions) appear to be educated
estimates based on General Motors "quality audit data". After updating AP-42 using
Bowditch's number, the values for crankcase emissions for agricultural equipment are 42.2
g/hr and 47.2 g/hr for tractors and nontractors, respectively.

The corrected AP-42 estimates closely agree with an EPA study of crankcase HC
emissions from nine on-highway vehicles with disabled PCV systems and disconnected fresh
air hoses on a gram/hour basis.70 The EPA found that the nine vehicles studied emitted, on
average, 1.92 grams of HC per mile (37.6 g/hr based on 3 bag FTP with average speed of
19 6 mph) over the first three bags of the FTP driving schedule with PCV and fresh air hose
disconnected. This value (37.6 g/hr) compares reasonably well with the updated AP-42
1-32
DRAFT - October 1991
-------
estimates of 42.24 and 47.2 g/hr for tractor and nontractor farm equipment, respectively, run
over a steady-state mode test.71
Aside from being an estimate, there may be other concerns regarding the reliability of
Bowditch's crankcase number (33% of uncontrolled HC exhaust) for use with today's
nonroad engines. The relationship between on-highway crankcase emissions and nonroad
crankcase emissions has never been documented for current year on- and nonroad engines.
Differences in operating cycles, machining tolerances, fuel delivery systems, etc., of on- and
nonroad engines compromise the ability to use existing on-highway engine exhaust and
crankcase emissions to generate nonroad emission factors For instance, technological
advances in combustion design for on-highway vehicles may not have been applied to
nonroad engines to date. In addition, those advances may decrease exhaust and/or crankcase
emissions but, perhaps disproportionally. Based on available data, there are two ways that
EPA can proceed to estimate nonroad crankcase emissions. First, EPA can adopt the number
provided by Bennett (70% of untreated exhaust HC emissions) or, second, EPA can apply
Bowditch's estimate (33% of untreated exhaust HC emissions). Despite the legitimate
concerns mentioned above, EPA believes that the Bowditch number remains the best available
estimate for crankcase emissions because it has been corroborated by EPA in 460/3-84-011.
In addition, it is more conservative than Bennett's number which has not been corroborated
by other sources. For purposes of estimating total emissions from the nonroad population,
EPA uses the "33% of untreated exhaust" value for all gasoline engines without closed
crankcases. Four-stroke engines with closed crankcases and all two-stroke engines are
assumed to have no crankcase emissions.
4.2. Diesel Crankcase Emission Factors
This section will present the best available HC, CO, and NOx emission factors for
nonroad diesel engines and describe the methodology for developing them.
Data for crankcase emissions from diesel engines is limited In fact, no studies which
explicitly investigate crankcase emissions from nonroad diesel engines have been found.
However, studies have been found for on-highway crankcase emissions. The most recent and
comprehensive paper has been published by Charles T Hare and Thomas M. Barnes.72 Hare

-------
and Baines studied three engines of which two were approximately half way between
overhauls and the other was relatively new. They found that hydrocarbon crankcase
emissions represent approximately 0.3 to 4.0 percent of corresponding exhaust hydrocarbon
emissions (0.006 to 0.017 g/kW-hr) when tested over the 13-mode test procedure. These
values are consistent with earlier studies conducted by Chevalier73 (approximate average
value = 0.0395 g/kW-hr74) of heavily worn diesel engines and Caterpillar (0.017 g/kW-
hr).73 The condition of the Caterpillar engine was not reported.
For the purposes of EPA's nonroad study, diesel crankcase HC emissions will be
assumed to be 2 percent (the mean of the range found by Hare and Baines) of untieated
exhaust hydrocarbon emissions unless a closed crankcase is implemented. In cases where the
crankcase is closed, EPA assumes zero diesel crankcase emissions. CO and NO, emissions
from diesel crankcases have only been reported by Hare and Baines, and Caterpillar Hare
and Baines reported CO and NO„ emission rates of 0.015 to 0.43 percent and 0 006 to 0.1
percent of exhaust emissions, respectively. Their numbers are corroborated by Caterpillar
who reported CO and NO„ emission rates of 0.23 and 0.076 of exhaust emission rates. For
the purposes of EPA's nonroad study, CO and NO, crankcase emissions from diesel engines
wdl be assumed to be 0.2 percent and 0.05 percent (the mean of the values reported by Hare
and Baines) of exhaust emissions, respectively

Chapter 5. Benzene
Based on review of the limited available data for toxic emissions of benzene and 1,3-
butadiene, EPA found it most appropriate in these cases to calculate emission rates as a
weight percentage of the total hydrocarbon emissions. Benzene exhaust emissions are
expressed as roughly 3 percent by weight of tailpipe exhaust hydrocarbons and crankcase
hydrocarbons for both gasoline and diesel engines. Only four studies of benzene emissions
were available for data applicable to nonroad configurations (i.e., non-catalyst).76 Analysis
of the data indicated that while there were large differences in the benzene emissions with
power and driving cycle when expressed in milligrams per hour, milligram per horsepower
hour, or milligrams per mile, the differences were far less when expressed as a percent of
total exhaust hydrocarbon emissions, as presented in the SwRI report.77 Refueling
emissions, which consist of spillage and vapor displacement, were assumed to consist of 1.7%
(weight) benzene which is the average summer and winter grade benzene content of in-use
gasoline (diesels were assumed to have negligible refueling emissions).

Chapter 6. 1,3-Butadiene
EPA has also chosen to express 1,3-butadiene emissions as a weight percent of tailpipe
exhaust hydrocarbons plus crankcase hydrocarbons The respective percentages used in this
study for nonroad diesel and gasoline engines are 1.6% and 1.3%.78 Emissions of 1,3-
butadiene were almost never measured in engine exhaust prior to the late 1980's, because the
procedures for doing so are relatively new. Only one study was available with measurement
from diesel engines and one study with measurements from non-catalyst gasoline automobiles
tested on unleaded gasoline. None of the studies found involved measurement from nonroad
equipment and duty cycles. However, due to the lack of additional information, EPA did
apply these emission rates to all categories.

Chapter 7. Nitrosamines
In addition to HC, CO and NOx emissions, it has been documented that nitrosamines,
which have been found to be carcinogenic in animals, are emitted from vented diesel
crankcases.79 While the contribution of motor vehicle emissions to the nitrosamine
concentration is not known for certain, Thomas M. Baines of EPA reports that tliree
researchers (Gordon,80 Shapley81 and Pellizzari82) have identified nitrosamines near
roadways and two of the three suspected automobiles as a source.83 Gordon reported
nitrosamine concentrations as high as 1.1 micrograms per cubic meter in the Los Angeles
basin. In his technical report, Baines proposes 109 cancer incidents per year if 1.5 million
people are exposed to 1.1 micrograms per cubic meter for 2 hours per day. Undoubtedly,
crankcase emissions of nitrosamines contribute to those cancer incidents. The reader is
referred to EPA's Integrated Risk Information System (IRIS) for a more complete risk
analysis and the technical report written by Thomas M. Baines for a more in depth analysis of
nitrosamines from diesel crankcase emissions and car interiors.

Appendix K. Adjustments to Data in Developing Inventory A
In developing Inventory A, EPA made several adjustments to annual hours of use,
load factor, and population data that are not reflected in the final reports from EPA
contractors. These adjustments are detailed below.
1.	Annual Hours of Use
Annual hours of use data provided to EPA from the PSR data-base were largely based
on the assumption that the use of various equipment types is either consumer or cotnmetciaJ.
In order to adjust for equipment types with a mixture of consumer and commercial use, EPA
adjusted the data by multiplying the regional hours of use reported by the contractor by
factors based on data submitted to EPA by OPEI,1 PPEMA,2 and CARB:3
Equipment Type	Adjustment Factor
Lawnmowers	2.5 (OPEI)
Tillers	2.2 (OPEI)
Trimmers/edgers/brush cutters	1.8 (PPEMA)
Leaf Blowers/vacuums	2.5 (PPEMA)
Snowblowers	1.5 (CARB)
These factors were calculated using the following general equation:
Adjustment Factor = (% consumer) x (consumer hrs) + (% commercial) x (commercial lirs)
In the case of trimmers/edgers/brushcutters, it was necessary to also weight by population the
annual hours of use for string and hedge trimmers, for which PPEMA submitted separate
estimates. Similarly, the value computed for leaf blowers/vacuums incorporates both
handheld and backpack versions
2.	Load Factors
DRAFT - October 1991	\r. i
-------
Load factor data provided to EPA from the PSR data base were in some cases too high
and in others too low. To correct the data, EPA substituted load factors determined by
CARB for the entire lawn and garden equipment category,4 and data supplied by EMI for
crawler tractors and rubber tired loaders.5 Load factor adjustments in the recreational marine
category are based on data from SAE paper 901596.6

3. Populations—Agricultural Equipment
For Inventory A, regional agricultural equipment populations were detennuied by
multiplying PSR national population estimates by the ratio of local over national census data
Census data exists for some types of agricultural equipment at the local level.
However, census counts do not differentiate between equipment that is inoperative or seldom
used and equipment used for agricultural activity. National population estimates from the
PSR data base are better estimates of equipment used regularly in agricultural activity than
the census counts. However, the census counts are accurate indicators of local distribution of
the equipment.
4. Populations—Recreational Marine Equipment
EPA used survey information provided by NMMA and local boat registrations
obtained from State Authorities by EEA to calculate the populations of boats at the CMSA
level. The NMMA survey data provided estimates of the proportion of boats registered in a
nonattainment area that are actually used in that area. The survey also estimated the
proportion of boats used in a nonattainment area that are registered outside of that area.
These proportions, coupled with local boat registration data, made it possible to estimate the
number of boats actually used in the nonattainment.

Appendix L. Regional and Seasonal Adjustments to Inventories
Annual hours of use data provided to EPA from the PSR data-base reflect different
usage patterns for different regions of the country." In developing Inventory A, EPA made
several adjustments to this data.
As ozone exceedances are typically a summertime problem and CO exceedances a
wintertime problem, EPA developed seasonal adjustment factors to reflect the use of
equipment depending on the season of the year
This appendix describes the assumptions made by EPA in calculating regional houis of
use and summertime and wintertime emissions.
1. Regional Adjustments
EPA has allocated the nonattainment areas studied to eight regions. Table-01 indicates
the nonattainment areas that fall into these eight regions, as well as the seasonal designations
for each region.
"This regional annual hours of use data is documented in the Eneigy and Environmental
Analysis final report, Methodoogy to Estimate Nonroad Equipment Populations by
Nonattainment Areas," available in the public docket.

In constructing Inventory A, EPA used annual hours of use data for each region as
supplied from the PSR data-base, as indicated in the EEA final report, except for the
following:
EPA created a "Mid-Atlantic Coast" region. The annual hours of use rates for
equipment in this region are determined by taking the average of the data for
the Northeast and Southeast regions.
EPA created a "Rocky Mountains" region. The annual hours of use rates for
equipment in this region are determined by taking the average of the data for
the Great Lakes and the Northwest regions.
Regional assumptions for commercial marine vessels were not necessary as
commercial marine equipment inventories were calculated directly at the regional level
2. Seasonal Adjustment Factors
L-2
DRAFT - October 1991
-------
The following tables list seasonal adjustment factors used to determine summertime
VOC and NOx emissions and wintertime CO emissions from nonroad engines and vehicles
Yearly emissions (tons per year) were adjusted according to the following formula:
tpsd=tpy xSAF	tpwd=tpyxSAF
winter
where the seasonal adjustment factors (SAFs) are defined as follows:
SAF	x ^ <2cfivt0' during summer
mmmer~ X	365 days
rr -a % activity during winter
wW~ X	365 days
In this analysis, the nation was divided for seasonal adjustment into three regions
based on average January temperatures:
Cold: < 35° F
Medium: 35-44° F
Warm: > 45° F
The cold, medium, and warm regions correspond to northern, central and southern
regions as defined in a 1973 report by Hare and Springer'
Northern: 43° north latitude and north
Central: from 37° to 43°
Southern: 37° and south
EPA seasonal adjustment factors have been calculated based on data from Hare and
Springer, the CARB Technical Support Document for proposed regulations applicable to lawn
and garden equipment,2 1987 SIP emission inventories, and the Motorcycle Industry Council
(MIC),3 and the NMMA,4 as detailed below Seasonal activity percentages were estimated
for the 3-month summer and winter periods as shown in Table L-02.

Hare and Springer reported construction seasons of 7, 8, and 9 months for the north,
central, and southern regions, respectively. This corresponds to summer activity percentages
of 43%, 38%, and 33% in the same regions. The 1987 SIP emission inventories for Denver
and Atlanta reported wintertime activity percentages of 10% and 20%, respectively. These
figures were applied to areas in the northern and southern regions. In this study, it was
estimated that the wintertime activity percentage in the central region was 15%.
Hare and Springer also reported agricultural seasons of 180, 225, and 270 days for the
northern, central, and southern regions, respectively. This corresponds to summer activity
percentages of 50%, 40%, and 34% in the same regions. The 1987 SIP emission inventories
for both Boston and Atlanta reported that 90% of agricultural equipment activity occurs
between April and October, yielding a wintertime activity percentage of 6% in both areas.
This figure was herein applied to all nonattainment areas to estimate wintertime agricultural
equipment activity.
Because of simdarities in the growing seasons, summertime activity percentages for
lawn and garden equipment (excluding chain saws) were estimated to be the same as those
for agricultural equipment. CARB estimated in the Technical Support Document for its
proposed regulations applicable to lawn and garden equipment that wintertime activity
L-4
DRAFT - October 1991
-------
accounted for about 6% of yearly activity This figure was applied to the southern region,
and the winterturie activity percentages in the central and northern regions were estimated to
be 3% and 0%. However, it was assumed that all snowblower activity occurs during the
winter. The industrial equipment seasonal activity percentages listed above are based on
seasonal adjustments used in several 1987 SIP emission inventories. Of those considered in
this studied, only that for Chicago reported any nonuniformity of industrial equipment activity
- the summer portion of yearly activity was reported to be 30%. This figure was applied to
the northern region, and the wintertime activity percentage was consequently estimated to be
20% Activity in the central and southern regions was estimated to be unifonrily distnbuted
across the year.
Due to the year-round nature of equipment use, no seasonal adjustments were made lo
activity for commercial marine vessels, airport service vehicles and logging equipment
(including all chain saws). The survey conducted by NMMA of recreation boat owners
included information on seasonal boat usage. These results were used to establish seasonal
adjustments for each of the eight regions used for regional hours of use adjustment as shown
in Table L-03.

Appendix M. Emission Inventory A
Inventory A is presented in two sets of tables which summarize emissions from
nonroad engines and vehicles, highway vehicles, and other area and point sources of
emissions. Each set of tables summarizes emissions in each of the 24 nonattainment areas
included in this study, as well as national emissions.
In the first set of summary tables, nonroad emissions are calculated using new engine
emission factors. In the second set of summary tables, nonroad emissions are calculated
using in-use emission factors.

Appendix N. EPA Use of Manufacturer Data In Inventory B
In developing activity levels for Inventory B, EPA used data supplied by
manufacturers or manufacturer associations where it was available. In some cases, EPA had
to adjust data for use in the inventory.
The kinds of data supplied and the adjustments to the data arc detailed below Part I
is a general overview of the data supplied by manufacturers and used by EPA in constructing
Inventory B. Part II contains more detailed adjustments made to the data for use in the
inventory.
1. General Overview
1.1. Equipment Manufacturers Institute (EMI)
EMI provided population data for several types of agricultural and construction
equipment. These equipment types are listed in Table N-01. Estimates of average engine-
rated horsepower were also available for these equipment types.
EMI estimates for crawler loaders were considered together with crawler tractors as
fitting within the Inventory A estimate for crawler tractors. Because cotton pickers were
included in Inventory A under "other agricultural equipment, EMI's cotton picker estunates
'were only considered in areas where the populations were higher than the Inventory A
estunate for other agricultural equipment.
There were several equipment types for which population estimates were not provided
by EMI, but for which EPA incorporated horsepower, annual use, and load factor estunates
from EMI in developing Inventory B. These included swathers ("windrowers"), mobile
elevating work platforms ("aerial lifts"), landfill compactors ("crushing/processing
equipment"), and square balers and bale wagons ("balers"). Because of either negligible
equipment populations or the absence of any matching equipment type, data for the following
equipment types was not considered: leaf loaders, milling machines, horizontal earth borers,
forage harvesters, augers, and cranes.

1.2. Outdoor Power Equipment Institute, Inc. (OPEI)
OPEI provided data on nonliandheld equipment types shown below ui Table N-02.
EPA combined OPEI's separate estunates for lawn tractors and garden tractors to replace the
data for lawn and garden tractors from Inventory A.
OPEI did not provide load factor data. However, OPEI expressed general agreement
with the data given in the Technical Support Document for CARB's proposed utility engine
N-2
DRAFT - October 1991
-------
regulations. Therefore, EPA used the CARB load factors in Inventory B.
Because OPEI reported separate annual hours of use estimates for commercial and
consumer use, EPA used OPEI's reported percentages of such use to construct weighted
average annual hours of use estimates. These and other adjustments to OPEI data are detailed
in a later section.

PPEMA also provided annual hours of use, horsepower, and load factor data. EPA's use of
this data is detailed in a later section.
1.4.	Industrial Truck Association (ITA)
1TA provided load factor, annual hours of use, and CMSA-level population estimates
for industrial forklifts which were used in Inventory B as provided.
1.5.	International Snowmobile Industry Association (ISIA)
ISIA provided national population and annual hours of use estimates for snowmobiles.
To obtain CMSA-level populations, EPA multiplied CMSA-level populations from Inventory
A by the ratio of ISIA national populations to Inventory A national populations.
1.6.	National Marine Manufacturers Association (NMMA)
NMMA provided EPA with survey information which was used to calculate annual
hours of use, average rated horsepower, load factors, and the ratio of boat use to boat
registration within nonattainment areas. CMSA-level populations were calculated by
multiplying loal boat registrations by this ratio.
2. Detailed Adjustments
2.1. Equipment Manufacturers Institute (EMI)
EMI supplied load factor, horsepower, annual hours of use, national and CMSA-level
population data for various types of agricultural equipment. The data supplied and the
adjustments made to die data are detailed below.
N-4
DRAFT - October 1991
-------
EMI Data and Adjustment
EMI supplied national horsepower and load factor, as well .as
national and CMSA level populations and hours/year separately
for crawler loaders and tractors. National hours/year were
estimated by population weighting the regional values supplied
by EMI over all 24 areas. To estimate aggregated hours/year for
all crawler loaders and tractors at the regional level, EPA
population weighted the regional values for both equipment
types. To estimate aggregated horsepower and load factor at the
national level, EPA weighted data for both types by
(population)(hours/year) and (population)(hours/year)
(horsepower), respectively.
Rubber Tired Loader	For wheel loaders EMI supplied national population, horsepower,
and load factor, as well as CMSA level populations and
hours/year. EPA estimated national houis of use by population
weighting regional values over 23 nonattainment areas.
Scraper	For scrapers, EMI supplied data as for rubber tired loaders.
Graders	For motor graders, EMI supplied data as for rubber tired loaders.
Off-Highway Trucks	For dumpers (off-road haulers), EMI supplied data as for rubber
tired loaders.
Excavators	EMI supplied national horsepower and load factor, as well as
CMSA level populations and hours/year separately for crawler
and wheel excavators. EMI also supplied national populations
for all excavators - EPA assumed a unifonn national distribution
of crawler and wheel versions. National hours/year were
estimated by population weighting the regional values supplied
by EMI over all 24 areas. To estimate aggregated hours/year for
all excavators at the regional level, EPA population weighted the
regional values for both types of excavators. To estimate
aggregated horsepower and load factor at the national level, EPA
weighted crawler and wheel data by (population)(hours/year) and
(population)(hours/year)(horsepower), respectively.
Tractor/Loaders/Backhoes EMI supplied data for backhoe loaders as for rubber tired
loaders.
Skid Steer Loaders	EMI supplied data for skid steer loaders as for rubber tired
loaders.

EMI Data and Adjustment
Skidder (logging)	EMI supplied data for log skidders as for rubber tired loaders,
except that national populations were not provided.
Rollers	EMI supplied data for rollers and compactors as for rubber tired
loaders.
Asphalt pavers	EMI supplied data for asphalt pavers as for rubber tired loaders.
Concrete pavers	EMI supplied only a national population estimate for concrete
pavers.
Cranes	EMI supplied only a national population estimate for cranes.
Trenchers	EMI suppled only estimates of the national population, average
rated horsepower, and load factor for trenchers.
Rougii Terrain Forklifts EMI supplied data for rough terrain forklifts as for trenchers.
Agricultural Tractor	EMI supplied national populations (based on census data),
horsepower ratings, and load factors, as well as CMSA level
populations and hours/year separately for tractors above anil
below 40 HP. To estimate national hours/year for both versions
individually, EPA weighted regional values over all 24 areas.
EPA estimated aggregated hours/year for all tractors at the
regional level by population weighting regional values. At the
national level, EPA estimated aggregated hours/year, horsepower,
and load factor by weighting regional values by population,
(population)(hours/year), and (population)(hours/year)
(horsepower), respectively.
Combines	EMI supplied data for combines as for rubber tired loaders.
Other Agri. Equip.	EMI supplied data for cotton pickers as for rubber tired loaders.
Balers	EMI supplied local population and annual use estimates for
square balers and bale wagons, as well as national data for
horsepower and load factor. EPA aggregated data for these two
equipment types in the same fashion as in for agricultural
tractors.
Aerial Lifts	EMI supplied only horsepower and load factor data for mobile
work platforms.

2.2. PPEMA Data
Population data ~ Population data were taken from a Heiden report* for 2-stroke
gasoline "Trimmers/Edgers/Brush Cutters"1, "Leaf Blowers/Vacuums", "Chain Saws <4 HP",
and "Chain Saws >4 HP". The populations were distributed to each CMSA based on the
EEA methodology. That is to say, the ratio of EEA's local (CMSA), 2-stroke, gasoline
population to EEA's national 2-stroke, gasoline population was applied to the national
population supplied by PPEMA:
The PPEMA chainsaw population was distributed to both the over and under 4 HP categories
based on the percentage of total chain saw population as reported by EEA.
Usage Data ~ Usage data for hand blowers, back blowers, trimmers/brushcutters,
hedgetrimmers, chain saws and cut off saws for commercial (professional) and consumer were
supplied by PPEMA in an earlier Heiden report.' That data was population weighted to
obtain average annual hours of use values for "Trimmers/Edgers/Brushcutters", "Leaf
Blowers/Vacuums", "Chainsaws <4 HP" and "Chainsaws >4 HP". National population data
are given in the second Heiden report (see Population Data above). Calculations for each of
these equipment types are shown below:

From data supplied by EEA:
•	0.32% of chainsaws have engines greater than 4 hp.
•	99.68% of chainsaws have engines less than 4 hp.
•	For those that are >4 hp, the average horsepower is 6.4 hp.
Therefore, by subtracting the number of hp-hrs attributable to the over 4 hp chain saws from
the total number of hp-hrs, an average hp and an average hours of use value may be obtained:

Horsepower Data — Horsepower data for chainsaws, trimmers/brushcutters, hand
blowers, back blowers and hedgetrimmers are taken from the 1990 Hieden report (page 18).
The horsepower for chain saws over 4 hp has been provided by EEA (6.4 hp). The average
horsepower value used for chainsaws less than 4 lip is 3.21 hp. This value was derived in the
discussion earlier regarding the hours of use for chain saws less than 4 hp The other
horsepowers have been population and usage weighted to provide average horsepowers for
"Tiiiimers/Edgers/ Brush Cutters" and "Leaf Blowers/Vacuums" as shown below:

Load Factor Data ~ Heiden suggested in the same report9 that most portable two-
stroke gasoline equipment operated at 50% of rated speed and full load. Therefore, a load
factor of 50% is assumed for "Trimmers/Edgers/Brushcutters", "Leaf Blowers/Vacuums",
"Chain saws <4 HP" and "Chain saws >4 HP".

tractors, garden tractors and tillers were supplied by OPEI£ However, because these
categories do not fully match those equipment types used in the nonroad study, some
aggregation and disaggregation was necessary. Lawn tractors and garden tractors were
combined to obtain a value for "Lawn and Garden Tractors". The tiller population was
disaggregated into "Tillers <5 HP" and 'Tillers >5 HP" and the riding mower population was
disaggregated into "Front Mowers" and "Rear Engine Riding Mowers". In addition, all
equipment populations were disaggregated into 2- and 4-stroke diesel and gasoline equipment
types per EEA's methodology for each CMSA" as shown below.

report. OPEI reported that 90% of lawn mowers are consumer and of those, 90% are 4-stroke
and 10% are 2-stroke.tf OPEI also reported that 10% of all lawn mowers are used
commercially and 85% of those are 4-stroke and 15% are 2-stroke. Therefore, the
percentages of 2- and 4 stroke lawn mowers are:
2-stroke: 90% x 10% + 10% x 15% = 10.5%
4-stroke: 90% x 90% + 10% x 85% = 89.5%
These percentages were applied to the CMSA populations supplied by OPEI to
disaggregate 2- and 4-stroke lawn mowers.
In some cases OPEI did not provide data for a particular CMSA, and EPA used data
from Inventory A. These cases are identified below:

Hours of Use ~ Hours of use data were taken from the OPEI report to EPAn
Additional assumptions specific to the equipment type are described below.
Lawn and Garden Tractors
Hours of use for lawn tractors and garden tractors were population weighted based on OPEI
CMSA populations to get annual hours of use for "Lawn and Garden Tractors" for each
CMSA. For example, the Baltimore CMSA 4 stroke diesel lawn and garden tractor annual
usage number is:
40,OCX) lawn tractors x 41 hrs
+ 29,326 garden tractors x 56 hrs _ 47 3 ^
40,000 + 29,326	~	™
** The average of Bakersfield and Fresno values were taken for the San Joaquin Valley and L A values were
assumed for the South Coast Air Basin CMSA
DRAFT - October 1991
N-13
-------
Tillers <5 HP and Tillers >5 HP
Hours of use for tillers were weighted by commercial and consumer populations provided by
OPEI in the addendum to their report. OPEI suggested that 40% of all tillers are used
conunercially and that 60% are used by consumers. Commercially used tillers are assumed to
operate 4 times as much as consumer tillers. For example, die average hours of use for tillers
in Atlanta is:
0.60 x 18 hrs
+0.40 x (18 hrs x 4)
39.6 hrs
Tillers above and below 5 HP were assumed to have the same usage characteristics.
Front Mowers and Rear Engine Riding Mowers
Hours of use for "Front Mowers" and "Rear Engine Riding Mowers" were assumed equal to
the riding mower value supplied by OPEI for each CMSA. This assumption will probably
underestimate the annual hours of use for "Front Mowers" because diey are used
commercially while "Rear Engine Riding Mowers" are not.
Lawn Mowers
Hours of use for lawn mowers are also weighted by commercial and consumer populations as
well as 2 stroke and 4 stroke populations. OPEI suggests that 90% of all lawn mowers are
consumer and 10% are commercial with commercial mowers operating 16 times as much as
consumer mowers. Of the consumer lawn mowers, 90% are 4-stroke and 10% are 2-stroke.
Of the commercial lawn mowers, 85% are 4-stroke and 15% are 2-stroke. For example, the
average hours of use for 2-stroke lawn mowers in Atlanta is:
0.90 x 0 10 x 28 hrs

Hours of Use
Slirecklers >5 HP and Shredders <5 HP
All sliredders are assumed to have the same usage rate, regardless of horsepower. The usage

The specialized turf care value supplied by CARB is utilized since both categories are
predominately wide area walk behind mowers. The value is 800 hours per year.
Horsepower
Carb reports a value for snowthrowers which is assumed identical to snowblowers The
horsepower value is population and usage rate weighted:

Appendix P. Transport and Nonroad Emissions
"Transport" refers to the phenomenon of windbome ozone and ozone precursors
causing elevated concentrations of ozone in adjacent air basins or areas hundreds of miles
away from the source of the precursors. Observations of high ozone levels downwind from
significant sources of ozone precursors and covering large areas has led to increased interest
in the long-range transport of ozone and its precursors. In the context of this study,
determining whether emissions can affect ozone levels some distance downwind from the
source of the emissions is particularly important in assessing the impact of emissions from
nonroad engines operated outside the boundaries of nonattainment areas. For example, one
question this study sought to address is "Could categories of nonroad equipment, such as
agricultural or marine pleasure craft, operated outside a nonattainment area, have an effect on
the level of a pollutant in the nonattainment area?" Questions like this need to be addressed
in order to determine and develop the most effective pollution control policy
Separate studies have concluded that transported pollution is a significant contributor
to ozone levels in the Northeast1 and in California.2 EPA and several Midwestern States are
beginning work on a major study of ozone transport across Lake Michigan; smaller studies of
pollution in western Michigan suggest that transported pollutants may be an overwhelming
contributor to ozone nonattainment there.3 Recent studies have found that pollution from Los
Angeles may contribute to haze in the Grand Canyon, approximately 250 miles
downwind.4 3 Elevated levels of ozone also are indicated causing crop damage in relatively
remote areas.6 Even without the completion of all of these studies, Congress acknowledged
the role of ozone transport in providing in the CAAA for the creation of regional transport
commissions in areas where "interstate transport . . . contributes significantly to a violation of
a national ambient air quality standard" (Section 176A(a)). Congress recognized that
interstate transport is significant in the northeast by explicitly creating a regional transport
commission encompassing 11 northeastern states and the District of Columbia.
In "1 Transport Studies," the major studies to date are summarized and their results
discussed. "2. The Effect of Transported Nonroad Emissions" focuses attention on EPA's
analysis of these studies in terms of the relationship between transport and nonroad emissions
DRAFT - Version 6 0
P-l
-------
Finally, "3. Transport Conclusions" focuses on some conclusions regarding transport.
1. Transport Studies
The major transport studies to date include the ROMNET (Regional Oxidant Modeling
for Northeast Transport) report, a joint effort among EPA and state and local air officials
from the Northeast and Midwest, and "Assessment and Mitigation of the Impacts of
Transported Pollutants on Ozone Concentrations within California," a report prepared by the
California Air Resources Board as required by the California Clean Air Act. The results of
these studies and their implications for the assessment of the impact of nonroad sources on
nonattainment are summarized below. This chapter also describes a smaller study addressing
the transport of ozone over Lake Michigan and ongoing studies of transport over Lake
Michigan and elsewhere.
1.1. Transport in the Northeast
The Regional Oxidant Model for Northeast Transport (ROMNET) project was begun
in 1987 as a cooperative effort between state and local air pollution officials and EPA. The
primary goals of ROMNET have been to assess the impact of transported ozone and ozone
precursors on nonattainment in the Northeast, especially the heavily urbanized Northeast
Corridor, and to develop a regional-scale photochemical model that will be used by
nonattainment areas to predict the effects of different strategies for attainment. The primary
relevance of the ROMNET work to the nonroad issue is its assessment of the overall
significance of transport in reducing ozone levels in the Northeast and the role of NOx in
ozone formation in that region.
Maps of the ROMNET region and the Northeast Corridor appear in Chart P-01. The
inventories of anthropogenic (manmade) emissions used in the model are based on the 1985
National Acid Precipitation Assessment Program (NAPAP) inventories. The ROMNET model

takes into account both anthropogenic and biogenic emissions; the reactivity of different VOC
emissions; the impact of seasonal, temporal, and day of the week on emission levels; and the
impacts of meteorology and topography on ozone formation and transport. The study
includes assessments of several different strategies for reducing ozone levels, including a draft
of the Clean Air Act and various combinations of VOC and NO, reductions.
To determine the ozone-forming potential of the emission inventory under "real-world"
conditions, the model incorporated meteorological data from actual historical ozone episodes.
Two recent serious multi-day ozone episodes were chosen for the model based on the
presence of "typical" ozone-generating characteristics. Most of the ROMNET results are
based on a model of the meteorological conditions during the severe ozone episode of July
4-18, 1988.
In evaluating the impact of various control strategies on reducing ozone in the
Northeast Corridor, including the strategy of reducing transported emission, the baseline 1985
emission inventories were projected to the year 2005. The emission from the different source
categories were assumed to increase according to predicted growth in highly correlated
indicators such as population or employment in the relevant industrial sector. In applying
emission control technologies to the source categories, it was generally assumed that the
controls could be completely in place and generating 100% of their theoretical effectiveness
by 2005, assumptions which are probably quite optimistic. One of the scenarios modeled
assessed the impact of relaxing these assumptions.
Three control scenarios were used to assess the impact of transport on the
nonattainment areas in the Northeast Corridor. One applied maximum control technology for
NO, and VOC to the 2005 inventories over the entire ROMNET area. Another applied the
controls only to sources within the Corridor itself. The third scenario applied maximum
control technologies only to sources that were outside the Corridor, yet were inside the U.S
portion of the ROMNET region. As an example of how these scenarios compare to the
version modeled in the Clean Air Act, the maximum control technology was assumed to
reduce, on average, overall VOC emission by 63% and NO, emission by 57% from the 2005
baseline level. The CAA version would reduce VOC emission by 32% and NO, emissions by
32% over the same region. In one scenario where controls were applied only outside the
Corridor, a packet of air was tracked from an origin in West Virginia up through the
DRAFT - Version 6 0
P-4
DRAFT - October 1991
-------
Massachusetts coast. Ozone and ozone precursor levels along its route were modeled and
compared to baseline (pre-control) levels. This comparison can be used to suggest the
distance over which transported pollutants can be expected to have a measurable impact on
ozone levels. The path of the air packet and the difference in pollutant levels between the
scenarios along that path are shown in Charts P-02 and P-03. As can be seen from these
figures, the effect of reducmg ozone precursors outside the Northeast Corridor was still
noticeable two days after the air packet had passed into the highly polluted Corridor. By the
time the air packet reached central Connecticut, it had traveled approximately 340 mdes from
its point of entry into the Corridor, and yet the reduction in non-Corridor emissions still
reduced the predicted ozone level in Connecticut by approximately 5 ppb.
Another assessment of upwind controls on specific nonattainment areas can be made
by comparing the ozone levels predicted in the Corridor nonattainment areas under the
different scenarios. The effect on these cities of reducing emissions from upwind sources is
shown in Tables P-01 and P-02. Table P-01 shows the impact of reducing only non-Corridor
emissions on ozone concentrations in Corridor cities. Table P-02 shows the difference in
predicted ozone levels for several cities between the scenarios with controls only in the
Corridor and controls over the entire ROMNET region. Not surprisingly, the effect is most
pronounced for those Corridor cities closest to the Corridor boundary, such as the
Washington/Baltimore area and Philadelphia.

The results show that a reduction of 65% of the non-Corridor VOC inventory and 60%
of the non-Corridor NO, inventory resulted in an average peak ozone reduction of 8 6 ppb in
the Corridor as a whole and 11.5 ppb average peak ozone reduction in the two western-most
nonattainment areas of Washington/Baltimore and Philadelphia. Very roughly, this implies
that 1% of the non-Corridor VOC and NO, inventories account for 0.14 ppb of the peak
ozone concentration in the Corridor cities on average and about 0.18 ppb of the peak ozone
concentration ui the Washington/Baltimore and Philadelphia areas.
While the reductions in ozone levels due to reduction in transported non-Corridor
emissions may not appear large, they should be compared to the reductions predicted for
other programs. For example, the ROMNET study also assessed the impact of a control
strategy that would convert the entire motor vehicle fleet in the Northeast Corridor to
medianol (methanol vehicles have less photochemically reactive emissions) and also reduce
the reactivity of solvent emissions throughout the Corridor. Average reductions in ozone
levels for the Northeast Corridor cities were approximately 5-8 ppb under this reactivity-based
control scenario These reductions are similar to the reductions predicted for reducing
non-Corridor emissions using maximum control technology for VOC and NO,. Neither
measure alone could reduce emissions enough to bring the Corridor into attainment.
According to the ROMNET report, 'The results suggest that without stringent upwuid
controls, ozone levels in parts of the Corridor may not be reduced to below the level specified
in the NAAQS even with stringent controls along the entire length of the Corridor." (ES-11)
Attainment of the ozone standard across the entire region may require not only maximum
control technology across the entire region, but additional substantial across-the-board
reductions in VOC emissions in New York City Again, we should note that the maximum
control technologies modeled here were assumed to achieve roughly twice the reduction, in
VOC and NO, emissions that are predicted to result from implementation of the minimum
requirements of the Clean Air Act. The report goes on to warn: "Considering rule
effectiveness and a more realistic representation of control programs, results show predicted
episode maximum ozone levels of just above 125 ppb in most sections of the Northeast
Corridor with the most stringent VOC/NOx/reactivity strategy simulated." (ES-11)

1.2. Transport in California
Section 39610(b) of the California Clean Air Act required the CARB to assess the
relative contribution of upwind emissions to downwind ozone levels. In June 1990, the Board
issued a staff report "Assessment and Mitigation of the Impacts of Transported Pollutants on
Ozone Concentrations within California," which assessed the impact of transport for 14
upwind-down wind area pairs.
The California report differs from the ROMNET report in several aspects. For ten of
the upwind-downwind area pairs, transport was not assessed using a complete regional air
quality model. In these cases, the CARB staff analyzed emission inventories for the upwind
and downwind areas, wind patterns that prevailed during nonattainment episodes, the timing
of downwind ozone peaks relative to peak precursor-generating periods upwind (e g. morning
and afternoon rush hours), and other available information to determine whether the
nonattainment was due primarily to upwind or downwind emissions.
Obviously, this method does not allow for quantitative precision about the impact of
upwind emissions on downwind ozone levels. The staff therefore limited its conclusions to
categorizing the impact of transport on the downwind area in each transport pair as either
overwhelming, significant, or inconsequential. "Overwhelming" impact is defined in the
CARB report as situations in which "ozone exceedances in the downwind area (other than
very near the boundary between upwind and downwind areas) occurred without any emission
contribution or with only a very small emission contribution from the downwind area." (1.2)
"Significant" transport impact was found in cases where "emissions from both the upwind and
downwind areas contributed to exceedances of the state standard," (1.2) and "inconsequential"
impact was found in areas for which "the staff determined that upwind emissions did not
contribute significantly to exceedances of the state ozone standard in the downwind area."(1.2)
Some upwind-downwind pairs fell in more than one category; that is, the importance of
transport varied substantially depending on meteorology so that transport might be judged
substantial under some conditions and inconsequential under others.
The CARB results are shown in Table P-03 For all the transport pairs studied,
transport was an "overwhelming" or "significant" contributor under at least some of the
meteorological conditions that typically prevailed during ozone exceedances. Transported

ozone and ozone precursors have an "overwhelming" impact on nonattainment in five
California nonattainment areas under some conditions and a "significant" effect in ten
nonattainment areas under some conditions. Some of these areas fall into both the
"overwhelming" and "significant" categories due to varying meteorological patterns among
ozone exceedance episodes. Most upwind sources of transported pollutants are urban areas,
but rural areas also may contribute to downwind nonattainment.
The proportion of VOC and NO, inventories from nonroad sources in six upwind areas
are shown in Tables P-04 - P-09 These tables show what is contributed from each of 5
nonroad categories, as well as the total nonroad contribution and total contribution from all
area and point sources. From this, an indication of the proportion of transported pollutants
from nonroad sources which impact the downwind area can be drawn.

1.3. Transport in the Lake Michigan Areas
Another area in which transport is believed to have a significant impact on ozone
nonattainment is Muskegon, Michigan. Muskegon is a city of 160,000 on the eastern shore of
Lake Michigan, approximately 185 km (115 mi) northeast of Chicago. Its persistent
nonattainment problems appear to be largely due to emissions from the Chicago area. In July
1988, during a high ozone episode for Muskegon, an instrumented research vessel recorded
ozone levels and wind patterns over Lake Michigan to determine if the high ozone levels
were being transported over the lake. High ozone levels were observed over the lake and
along the shore south of Muskegon. Back trajectories of the air parcels containing the ozone
levels showed that these air parcels originated along the heavily industrialized urban southern
shore of Lake Michigan. Further evidence of the importance of transport in causing this
exceedance is the fact that Grand Rapids, a much larger and more heavily industrialized city
than Muskegon approximately 50 km east of Muskegon, approached, but did not exceed, the
NAAQS for ozone, although meteorological data were favorable for ozone formation in both
Muskegon and Grand Rapids Back trajectories of the air parcels entering Grand Rapids on
this day indicated that they passed over the southern shore of Lake Michigan outside of the
urban, industrialized Chicago-Gary area.
EPA's Region V currently is coordinating the development of an Urban Airshed
Model that will encompass the greater Lake Michigan area. The Lake Michigan Oxidant
Study (LMOS) will assess the transport of ozone precursor emissions and ozone across the
lake to better explain the effect of emissions from eastern Wisconsin and the Chicago/Gary
area on ozone levels in Michigan. The study will include many new inventories to be
developed by EPA and the states bordering Lake Michigan. The Lake Michigan Oxidant
Study will be completed in 1993.
2. The Effect of Transported Nonroad Emissions
The fact that ozone is a regional and not a local problem has been demonstrated by
studies described previously and is widely understood and accepted. Congress demonstrated
their understanding and acceptance of this concept by mandating the creation of regional

transport commissions in the CAAA. Transport work now concentrates on assessing the
factors impacting transport and developing a way to model and quantify the transport effect
For the purposes of this study, EPA has used information gathered in developing
ROMNET to tentatively quantify the effect of transported nonroad emissions on air quality in
the Northeast Corridor. The impact of nonroad non-Corridor emissions may be roughly
assessed by looking at the proportion of the non-Corridor inventory generated by the nonroad
source categories. These categories are: nonroad diesel, nonroad gasoline, military aviation,
civilian (commercial) aviation, general aviation, gasoline vessels, diesel vessels, and
residual-fuel vessels. Their proportions of the inventory are shown in Table P-10
Table P-10. 1985 Nonroad Proportion of Non-Corridor Base Year Inventories (%)
VOC	NO.
Nonroad diesel	0.24	3 01
Nonroad gasoline	1.51	0.94
Vessels
gasoline	0.46	0 04
diesel	0.04	0.35
residual fuel	—	0.03
Total Nonroad	2.26	4.38
Several caveats should be observed in interpreting these numbers. First, the inventory
proportions quoted in Table P-03 are for the base year 1985, not 2005, the year for which the
control scenarios were modeled. Inventories for 2005 were not available from the ROMNET
calculations because of the way in which inventory numbers were aggregated, speciated, and
adjusted by the model during its projections. Also, the myriad meteorological and
photochemical assumptions built into the ozone level predictions quoted in the last chapter
make quantitative generalizations about the effects of changes in transport on ozone levels
somewhat hazardous. Nonetheless, these calculations can help to illustrate the relative
magnitude of the effect of transported pollutants from nonroad sources on several important
nonattainment areas Taken together, the categories of nonroad engines within the scope of
DRAFT - Version 6 0	P-20	DRAFT - October 1991

this report accounted for 2.3% of the non-Corridor VOC inventory and 4.4% of the
non-Corridor NOx inventory in 1985. Given the correlation of non-Corridor inventory
reductions and Corridor peak ozone reductions posited above,1 it appears that transported
pollutants from nonroad sources account for roughly 0.5 ppb of the peak ozone concentrations
in the Corridor cities as a whole and 0 6 ppb of the peak ozone concentration in the
Baltimore/Washington and Philadelphia areas. One context for assessing the importance of
these impacts on urban ozone would be to compare the magnitude of the effect of transported
nonroad sources to the levels of ozone predicted in the major northeastern cities after the
implementation of the Clean Air Act mandates modeled by ROMNET. As shown in Table
P-11, transported pollutants from non-Corridor nonroad sources would account for roughly
0.3-0.45% of the ozone level along the East Coast during ozone nonattainment episodes.

1.	Transport from ail sources from non-Corridor areas into the Northeast Corridor
contributes to nonattainment in several cities in the Northeast.
2.	Currently, nonroad emissions outside the Corridor area account for approximately
2.3% of the VOC non-corridor inventory and 4 4% of the NO, non-corridor inventory
(see Table P-10).
3 In the absence of regulation of nonroad sources, the proportions listed in 2 above will
probably increase in the future, as regulations are applied to more of the remauiing
source categories and are further tightened on categories already subject to emission
regulation.
4. Nonroad sources cannot be discounted as insignificant merely because they are outside
the boundaries of nonattainment areas.
Again, as the studies quoted in this chapter have demonstrated, ozone is a regional and
not a local problem. Airborne transport of ozone and its precursors does not stop at city,
county, or state boundaries. Apparently, it is not uncommon for transported pollutants to
impact ozone levels 200 miles from the source of the emissions. 'At this time, it is difficult to
quantify precisely the distance ozone and ozone precursors typically travel, but clearly a
complete list of sources contributing to urban nonattainment cannot stop at the nonattainment
area's border. Thus, nonroad sources outside nonattainment areas may be assumed to
contribute to urban nonattainment.
EPA and state officials are continuing to study the role of transport in nonattainment
Therefore, our understanding of transport should be considerably expanded within the next
few years. EPA's Office of Air Quality Planning and Standards (OAQPS) is currently
working on extensions to the results presented in the ROMNET draft study. These include
applying the regional oxidant model to the Southeast and Midwest, in addition to modeling
the effect of the Clean Air Act, as actually passed, on the Northeast. Much of this work will
provide support to states containing nonattainment areas in their efforts to comply with the
inventory and air quality modeling requirements of the Clean Air Act. OAQPS will also be

of nonroad emissions. Currently, efforts are underway to establish a new national inventory
for nonroad engines and other area and mobile sources, called the Aerometric Information
Retrieval System/Area and Mobile Source file (AIRS/AMS). The results of these regional
models will be re-evaluated using the new inventories as soon as they are available in 1993
