Appendix B. Ozone Formation
This appendix provides a brief explanation of the process by which ozone is
formed, followed by a list of other sources expanding on die role of NO^ and VOCs.
Description
The prediction of ozone (O3) levels and the development of control strategies for
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 series of
reactions between volatile organic compounds (VQCa), oxides of nitrogen (NOX), and ambient
oxygen. The concentrations of ozone and its precursors ait dynamic and nonlinear. Thus,
ozone concentrations ane not necessarily additive, but depend on the concentrations of all
compounds involved in atmospheric chemistry. VOCs are emitted by anthropogenic sources,
such as evaporation of gasoline and solvents, and by biogenk 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
oiorte, depending on the amount of VOCs present.
Ozone is produced when atomic oxygen (O) reacts with molecular oxygen (Q,) in this
reaction;
O + G! + M -»> O, + M
where M is a third body that removes the energy of the reaction and stabilizes the O,
molecule. The atomic oxygen necessary for this reaction is produced primarily from the
photodiwociation of NO2, according to this reaction:
j •+• 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 hart is associated with ozone
FINAL - Ncromber 1991

Nooroad Engine ani Vehick Emission Study
pollution, even though ozone itself is a colorless gas. In the above reactions, NOX is involved
in creating ozone.
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 + O, -> NOj + Oj
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 pefoxy radicals (ROj),
which are foimed by the reaction of hydroxyi radicals (OH) with VOCs, nitrogen dioxide can
be regenerated from nitrogen oxide without consuming ozone, as in this reaction:
ROj + NO -> NO, + 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 N

Appendix C, Ozone and CO Nonattaunnent and Air Toxk Risk Estimates
Two of the most persistent air quality problems in the United States are the
nonattainment of National Ambient Aii Quality Standards for carbon monoxide (CO) and
ozone. Table C-01 lists the areas which faii to meet standards for CO and ozone. In addition
to these nonattainment problems, concern regarding the risks associated with motor vehide 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, aa were CARB analyses for seven air
basins in California. Table G-Ql provides a list of these areas,

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 whert possible
and substituted new emission factors in order to generate new inventories based on the SIP
data- The emission inventories developed by CARB for nonroad mobile sources were much
more detailed tlian 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 mobUe sources in slightly different ways than EPA did in developing
new emission inventories. In Table G-01, the SIP and CARB categories are compared with
the ten equipment categories developed by EPA for diis study,

Emission Inventories Developed Uatng SIP ind CARB Dita
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 arc developed as pan 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 aie projected based on the baseline
emission inventory. State air quality planners generally develop emission inventories for
nonatrainment areas following the methodologies outlined in the existing EPA guidance,'
EPA provides information on preparing emission inventories for SIPs in a series of
five documents entitled Procedures for Emission Inventory Preparation (henceforth simply
Procedures). The first volume gives an overview of the methodologies and reporting
requirements for emission inventories and subsequent volume* give the methodologies
whereby activity levels may be estimated at the county level for point sources,1 nonroad and
highway mobile sources/ 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 arc,
in such cases, often reported as "off-highway mobile sources" in the area source inventory.
This b likely due to the fact that highway vehicles ore 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. Slnulady, fuel consumption (e.g. heating
oil) in commercial and industrial applications may be estimated using employment statistics in
the applicable industries. Where possible, the emission factors in the EPA guidance
document were updated to include more recent data. A full discussion of the development of
revised SIP emission factors is contained in Appendix L
FINAL - November 1991
-------
Nomoad Earine and Vehicle Emission Study
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 probEem,r CO emissions are often expressed in tons per winter day
(rpwd). In its analysis of SIP emission inventories, EPA used those seasonal adjustments mat
were reported in the SIPs,
For this study, EPA has examined several of the draft SIP inventories developed by
states for the 1987 and 1988 BY. Because of die CAAA requirement that states develop
emission inventories for the 1990 BY, many of the 1987/1988 draft inventories have not been
finalized at this time. However, because the 1990 BY inventories will not be completed in
1991, only die earlier inventories may be considered for this stody, despite the fact that they
are still in draft foim.
In analyzing 1987 base year emission inventories from SIPs, EPA extracted the
activity levels calculated for nonfood 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 die 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.

Emissioa IOVHIHTOS Developed Using SIP and CARB Pita
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? which documents for each nonattainment air a
studied the nonraad engine and vehicle activity levels derived, the emissions calculated, and
the emissions from other sources (i.e., highway vehicles, other aiea and point sources).
Emission inventories prepared by the CARS 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 art generally more refined than those that have been developed by states
following the existing EPA guidance. Furthermore, they use different nonroad mobile source
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 wen 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
recently developed emission inventories are; utility and Uwn and garden equipment,6 heavy-
duty farm and construction equipment,7 and commercial marine vessels.* * These
inventories are also summarized in the following tables.

Appendix I. Emission Factor Development
This appendix details the origins of the emission factors used to calculate emission
inventories for this study.
Foi this study, emissions from internal combustion engines are broadly grouped into
one of four source categories baaed on the origin of the emission: tailpipe exhaust, refueling,
evaporative, and crankcase emissions. Each of those categories is further divided by
pollutant: HC, CO, NQ^ and other toxic pollutants including paniculate 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. En simple terms, the emission factor ts 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 exhaust, refueling, evaporative,
and cranfccase 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 paniculate 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).1 Emission rates for nitrosamines, benzene, and 1,3-
butadiene are discussed ki 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 I-Ql through 1-17 are located at me end of the appendix.

The emission factors necessary far calculating Inventories A and B also required some
aggregation, although not to the extent necessary for the SIP inventory calculation. The
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 (sec "1.5. Light Commercial Equipment < 50 hp").
1.2.1. Dto«J
The most recent, up-to-date published emission factors for agricultural and
construction diesel equipment ace reported in the CAL/ERT report,7 and in a recent report to
CARS by Energy and Environmental Analysis (EEA)1 on heavy-duty construction
equipment. In general, the emissions for the CALBERT report were measured on a 13-mode
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 lift of recommended emission factors foe 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 EMV<>
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 similar
For agricultural equipment, EPA has selected the factors presented in the CAUERT 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
the CAL/ERT report. The factors were converted from units of g/hp-hi to lb/1000 gallons of
fuel consumed by using a BSFC of 0-4 lb/Hp-hr9 and diesel fuel density of 7.1 tb/gallon.10
Table 1-08 shows the aggregation of the emission factors in terms of g/hp-hi, while
Table 1-08 shows the lb/1000 gat 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-42" factors which were derived from CAL/ERT11
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 paniculate matter. The emission factors
for paniculate matter and aldehydes used in the study for Inventory A are those reported in
the Fourth Edition of AP-42. The test results from a recent joint EPA/Industry program to
assess test cycles for nonjoad equipment are presented in Table I-10. The paniculate
emissions from the four 1991 diesel nonroad engines tested suggest that these newer engines
have considerably lower emission rates than the emission factore reported in AP-42 (which
are derived from a 1973 Southwest Research Institute study)13. Paniculate emission rates for
the four new engines tested are two to five times lower than the emission factors used for
inventory purposes. Therefore, as the older engine fleet is replaced by the newer engines
which emit lower levels of paniculate matter, the paniculate emission inventory will decrease
accordingly. Although, the emission factors reported in AP-42 are assumed by EPA to be
more representative of the average engine in the population, the test results on new engines
suggest that these emission factors may overestimate paniculate emission nates. To some
extent, technology improvements in highway engines to meet the paniculate emission
standards (beginning in 1988) may have been carried into nonroad versions of these engines
with the accompanying paniculate emission benefit. Also, the data from the EPA/Industry
program indicate that engine manufacturers who do not produce engines for highway
applications have shown a decrease in paniculate Levels from 1973 to 1991.
The Engine Manufacturers Association (EMA) expressed concerns regarding the
representativeness of the AF-42 data which was generated in 1973. As a result, the

I.Z.Z. Gasoline
The emission factors for gasoline agricultural and construction equipment selected to
be used in calculating emission inventories are from the Fourth Edition of AP-42, The other
sources that reported emission factors for diesel equipment did not report gasoline equipment
emission factois. The CAL/ERT report did suggest using 2,8 g/hp-hr HC, 163 g/hp-hr CO,
and 7,8 g/hp-hr NO^ for gasoline powered equipment (Tables I-7(c) and I-8(c», However,
the emission factor* in AP-42 are more specific to equipment type and will be used for the
study-
The particuhue emission factors in AP-42 were derived from paniculate 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. Oven today's leaded fuel
contains very little lead. Since particles consisting of lead oxides are the main paniculate
emission from leaded-gasoline fueled engines, the AIM 2 emission factors are not
representative of emission rates from equipment operating on currently available gasoline,
Therefore, me values reported in AF-42 were not used in this study. Instead, a value of
1 .64 Ib/lQOQ gallons was used for the paniculate emission factors for gasoline fueled
equipment. This value is based on a recommendation from SwRI in the Nonroad Emission
Factors of Air Tories1* report to EPA. Where necessary, die 1.64 Ib/lQOG gallon was
converted to 0,06 g/hp-hr by assuming BSFC 0.5 Ityhp-hr1* and density of gasoline of

were based on testa performed on eight diesel engines and four gasoline engines. No
emissions data wore Available for LPG-powered aerial lifts, foridifts, and sweepers/scrubber*
The only emission data found for LPG-powered equipment is from two gasoline engines
which were converted to operate on LPG, One engine wa$ a 4.5 hp overhead valve walk
behind mower engine tested by Southwest Research Institute.30 Compared to the emissions
when the engine was operated on gasoline, the engine emitted 38% less HC, 55% less CO,
147% more NOX, 13% less FM, and approximately the same level of aldehydes when
operated on LPG. The other engine was a 12,5 hp utility engine tested by Qnati.JI
Compared to operation on gasoline, this engine emitted 72% less HC, 80% less CO, and
347% more NO* when operated on LPG, Since neither of these engines an representative of
the larger industrial equipment engines, the emission data cannot directly be used for
developing an enussion factor. However, the relative differences between the gasoline and
LPG emission molts for the two engines can be used to approximate the LPO 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.

Very little data exists on emission rates from snowmobiles. The best currently

The factors in terms of g/hr were converted to g/hp-hr for use in calculating emissions
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 the teat cycle. The g/hr value was then divided by 5.8 to
determine g/hp hr. In a recent response to CARD mail out #90-70 entitled A Proposal to

reported snowmobile emission factors of 216 g/hp-hr HC+NOX> and 564 g/hp-hr for CO.

Chapter 2. Adjustments to Tailpipe Emisskm Factors
Z.I. Adjustments for Teat 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, for which the 8-mode cycle does not provide a good
measurement for equipment that encounters transient operation. On the other hand, the
transient cycle used to simulate highway heavy-duty engine operation may not be as
appropriate to simulate nonroad equipment transient operation. However, EPA expects that
emission levels of nonroad equipment that encounters transient operation in use will be better
represented by levels during 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 teat emissions (Table I-10). Based on the currently available data (four enginesi
these ratios were: 1.4 for HCT 2,0 for CO. 1 for NOX, and 1.6 for particulates. These ratios
were then applied to the emission factors of diesel fueled equipment types that are expectai

factors of gasoline fueled equipment types as there was no available data on transient
steady state test cycle emission comparisons for gasoline fueled engines.
.l. Ad test meats for In-Us 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, die 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 tn-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 (three 4-stroke
engines and two 2-stroke engines) and performed emission tests using the SAE II OSS
procedure. A description of the engines and the emission test results are shown in Table M4,
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. 4-Stroke Gasoline Engines Under 20 hp
The 4-strake engines tested by SwRI showed 2, 1 times the HC emissions, 1 .9 times
the CO emission*, 0.4 times the NO* emissions, and 3.6 rimes the paniculate emissions of
new engine emissions (Table 1-14). These engines exhibited problems of low power, head
gasket leaks and others which are described in the SwRI report." Although only a very
small sample of 4-stroke engines were tested, the trend of high HC, CO, and particulars and
low NO* 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-02c)
represent a rough approximation of in-use nonroad engine emission levels,

2.2J. 4-Stroke Gasoline Engines Over 20 hp
In 1983, the Engine Manufacturer Association (EMA) and the EPA conducted a joint
in-use test program to develop in-use emission factors for heavy-duty diescl and heavy-duty
gasoline engines. The program used 1979 and 1982 model year pie-controlled engines and is
the best available source of data for representing in-use nonroad 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-ose adjustment factors some broad assumptions were made.
Typical in-usc engines were assumed to be have accumulated 55,000 miles, which is half of
the useful life of 110,000 miles defined hi the regulations for heavy-duty highway gasoline
engines. 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-OZc), The NQX emissions site wed no significant
change with mileage accumulation and therefore NOX emission factors were not adjusted.
Paniculate 4-stroke engine emission factors were not adjusted since no data was avail able.
2.23, 2-Stroke Gasoline Engines
As discussed above, SwRl tested two 2-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 1-14. 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 available for 2-stroke engines and these
data were widely divergent, EPA did not estimate in-use adjustment factors based on these
points. Instead, die factor* used for 4-stroke engines Less than 20 hp weir used for HC anil
CO emissions for 2-stroke engines with average horsepower less than 20, as the 2-stroke data
bracketed the 4-stroke results for these pollutants (i.e., one data point was much lower and
one was much higher). The 4-stroke NOX adjustment factor of 0.4 did not seem appropriate
to apply to 2-strokes since both the 2-sttoke engines tested by SwRl showed nearly equal or
higher emission levels than new engine emission factors- Therefore, no adjustment was made
HNAL Noveoifcer 1991 "~~
-------
Nonroad EnidM and Vehicle Emission Study
to NOS new engine emission factors. Also, the 4-stroke particular 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 2-stroke engines.
Therefore, no adjustment was made to the 2-stroke participate new engine emission factor.
For 2-stroke engines with average horsepower greater than 20, the adjustment factors for 4-
strokes greater than 20 hp were used.
For 2-stroke outboard marine engines, these adjustments for HC and CO emissions
would likely overstate in-use effects due to the more unique characteristics of these engines,
Outboard engines air built to be more durable than the smaller, less expensive utility/lawn
and garden engines, and to operate in environments where airborne dust and din are iess of a
problem. Therefore, an adjustment factor of 1-2 was applied to HC and CO for 2-stroke
outboard engines.
The National Marine Manufacturer Association suggests that hvuse adjustment factors
for 2-stioke outboard engines should not be included in the calculation of emission
inventories until further investigation can be done. NMMA states mat 2-stioke engines do
not exhibit the same deterioration in efficiency after extended use as 4-stroke engines and that
boaters are more likely to maintain their engine* for safety reasons. Also, an NMMA
member company recently compiled data on an U-horsepower, 2-stroke outboard thai had
accumulated 2,500 hours on the company's durability cycle which showed no increase in
specific emission. However, EPA expects that using new engine emission factors for
calculating in-use inventories would understate actual in-use emission levels. The in-use
adjustment factors for 4-stroke gasoline engines greater than 20 hp were adjusted downward
by a factor of about 2 as an estimation of the in-use adjustment for 2-stroke outboard engines.
For the in-use estimate, an adjustment factor of 1.2 was applied to HC and CO for 2-stroke
outboard engine emission factors.
2.2.4, Diesel Engines
As discussed earlier, EMA and EPA conducted a joint program to assess the emission
factors of pre-controlkd heavy-duty diesel and gasoline engines. For diesel engines, the data
showed no increase in HC, NOX, and only a slight increase in participate matter emissions

Chapter 3. Refueling and Evaporative Emission Factors
Hydrocarbon (HC) refueling and evaporative emission factors are presumed in this
section. A list of nonroad equipment and their evaporative and refueling emission factors
may b« found in Tables I -01, 1-02, 1-15 and 1-16. Table 1-15 and 1-16 are also good
summaries of how refueling and evaporative emission factors were calculated for gasoline and
diesel fueled equipment, respectively.
This chapter is divided into four sections that (1) introduce the concept of refueling
and evaporative emissions, (2) present fuel tank volume data, (3) present refueling emission
factors, and (4) present 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. Concepts of RefiMiMng and mot atfrc
The concepts of refueling and evaporative emissions are now presented. These
concepts are applicable to both gasoline and diesel fueled equipment (although perhaps more
pertinent to gasoline fueled equipment than diesel fueled equipment).
3.1.1. RefueUnf EmJsstam
There are two components of refueling emissions: spillage and vapor displacement.
Spillage emissions, or simply spillage, are those emissions thai result from fuel spilled 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
spdled while transferring the fuel from the storage container to the equipment. Vapor
displacement emissions, or displacement, are those emissions that result from displacing fuel
vapors in the fuel tank or storage container with liquid fuef . 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 atmosphere by the incoming fuel, For the purposes of diis study,
only fuel lost while refueling the equipment is considered. One would expect, however, that
M6 FINAL - November
-------
Emission Factor
refueling emissions from the refueling of storage containers would be on the same order of
magnitude as the refueling emissions from equipment,
3.1.1. Evaporative Emissions
Evaporative emissions are losses generated by the evaporation of unhurried fuel.
Evaporative emissions do not pass through the combustion chamber. 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 specific 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 emissions are those fuel vapors which occur while toe
equipment is not operating and are attributable to natural changes in ambient conditions
(temperature, pressure, etc). In addition, diurnal losses occur only during those portions of
the year when the equipment is used relatively regularly (every few days),14 Running loss
emissions are those emissions which do not pass through the combustion chamber while the
source is in operation. Resting loss emissions are those emissions 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 diurnal emissions will be considered due to the tack of
data for hot soak, resting loss and running loss emissions from nonroad engines,
3.2. Developing Effective Fuel Tank Volumes
This section will present those data and assumptions which were used to arrive at
effective fuel tank volumes for gasoline and diesel equipment. Fuel tank volumes are not
discussed with the presentation of other data to avoid tedious duplication of discussion, Both
evaporative and refueling emission factors use fuel tank volumes as part of their calculation
FINAL - November 1991
-------
This section, Developing Effective Fuei Tank Volumes , is divided into two subchapters
The first subchapter presents effective fuel tank volumes for gasoline equipment and the
second subchapter presents effective fuel tank volumes for diegel equipment.
3,2X 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 derived from each of these sources are
discussed below.
Manufacturers* Gasoline Ffcel Tank Data - Manufacturer! were asked to supply
fuel tank volumes for several piece* of gasoline equipment. However, the fuel tank volumes
provided often did not quite match the equipment categories used by EPA in this study and
aggregation was required. When possible, a weighted average of pertinent fuel tank volumes
was used to generate an effective fuel tank volume for the particular equipment category and
emission source. If the data supplied by manufacturers matched an equipment category
exactly, the data were used directly.
Effective fuel tank volumes are not necessarily constant for refueling and evaporative
emission factor calculations. Instead, an effective fuel tank volume should be calculated for
each emission and equipment type because refueling and evaporative emissions are functions
of different factors. A particular weighing factor may be important when aggregating fuel
tank volumes for diurnal emission factor calculations, but that same weighing factor may not
be important when calculating refueling emissions, or vice-vena. For example, walk behind
lawnmoweis 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 (large fuel tanks), their season length is probably longer The effective fuel tank
volume should account for population sizes and length of seasons. Other weighing factors are
used when calculating an effective fuel tank volume for refueling emission factors. Refueling
emissions are influenced by the amount of fuel consumed, which is a function of population,
i
horsepower, load factor, brake specific fuel consump'ion and usage rate. The effective fuel
a FINAL - November 1991
-------
tank volume for refueling emissions should account for these factors. Therefore, the purpose
for which the average fuel tank volume is calculated dictates how individual fuel tank
volumes are weighted.
The discussion below presents effective gasoline fuel tank volumes for evaporative and
refueling emissions. Fuel tank aggregation for calculation of gasoline refueling emission
factors are discussed first and fuel tank aggregation for calculation of gasoline evaporative
emission factors are discussed afterwards. The aggregations were often reduced to mere
population weighings or averages because so many weighing factors were not available (i.e.,
if a particular weighing factor is not known, then the category is assumed to be homogeneous
with respect to that weighing factor). For this reason, gasoline fuel tank volumes used for
Calculation of evaporative emissions are the same as diose used for refueling emission factors
unless specifically indicated as different in the section titled Manufacturer's Date far
Calculation of(^yol\ne Evaporative Emission Factors. In addition, several fuel tank volumes
were taken directly from data supplied by manufacturers but those are not discussed below.
Those data are readily identified in Table 1-15,
Manufacturer's Data for Calculation of Gasoline 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

EPA Generated GftOOiiite Fuel Tank Volumes « Several fuel tank volumes 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 Sets 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 subchapter. The third alternative Is the use of fuel tank volumes based on
the engineering judgement of EPA pertonneL For all equipment, manufacttucr suggested
values were used when available and if not, then the fust, second and thud alternatives were

with engines of 15 hp or more. The result of that regression Ls:
Fuel Tank Vol. =0.51 x Net HP ; K1 = 0.82
Articulated tractors and some fcller-buncher* 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 ail equipment used in that regression as well as a plot of the data is
presented in Table 1-17,
As indicated in Table 1-17, 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 he 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.
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
regression may slighdy overestimate gasoline spillage emissions but underestimate gasoline
diurnal emissions,
Due to the lack of data, fox much of die equipment, the regression line was used
extensively (approximately 23% of all equipment types). The gasoline equipment for which

3.j^ MethodoiogT Used to Calculate Refilling Embaion Factors
This section will present the methodology and data used to calculate refueling
emission factors for gasoline and diesel equipment. The reader is referred to section 3.1,
Concepts of Refueling and Evaporative Emissions, for a definition of refueling emissions,
3 J.I. 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 OPE1 for lawn and garden equipment (primarily standard walk behind
lawnmowers). Briggs & Stratton has presented a value of 45 grama (approximately 1.5 oz.)
per refueling and suggested that the value be reduced to 22.5 g/reftwling as the user becomes
familiar with the equipment." 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).4*
The discrepancy between the Mobile4 vafae 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 A Stratton are probably closer to die true value for
nonroad engines which are typkally 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 pomp, spillage is assumed to be 3.6 g/rcfueling. EPA chose
the OPEI over the Briggs & Stratton value because it is based on substantially moie data.
The method of refueling (pump or container) is discerned by equipment type and fuel
tank size. Lawn and garden (except chippers/stump grinders), recreational, and light
commercial equipment aie assumed to he refueled from portable fuel containers. In addition,
any other equipment with fael tank volumes less than 6 gallons4* "* are assumed to be

Vapor Displacement — Vapor displacement emission values were taken from on-
highway data because no estimates for vapor displacement emissions from nonroad engines
can be found in literature. However, the on-highway and nonroad displacement values should
be similar since the gasoline composition for both is the same. EPA has implemented the
model proposed by Rothman and Johnson of the EPA for on-highway vehicles to predict
displacement emission**7:

Rothman and Johnson also recommend seasonal national average values for the model
variables. EPA has matched those averages with equipment types for the particular season of
the year in which the equipment is most likely to operate, Rothman and Johnson's summer
and annual RVP values are not used in anticipation of the new RVP standards which will
limit RVP to 10.5 during the summer of 1992. The annual average RVP was recalculated

dispensed from underground storage tank*. 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 "pomp dispensed" values suggested
by Rothman and Johnson are used only for equipment refueled from gasoline fuel pumps. For
equipment refueled from fuel containers, the values Td an; assumed equal to the equipment
tank temperature. Thus, dT Is zero.
It can be correctly argued that the dispensed fuel temperature for many nonattainment
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. The best available national emission factors are used
for all cities. A list of equipment and the associated displacement emission factors as well a*
total refueling emission factors is located in Table 1-15.
To make the refueling emission factors compatible with the populations and usage
rates used in the study, die refueling emission factor units were changed front grams per
gallon to grams per horsepower hoiu (except some recreational equipment which are
expressed in g/hr and marine vessels which are expressed in g/gal) by multiplying the original
value by the brake specific fuel consumption (BSFC). To facilitate that change, assumptions
regarding BSFC were necessary. BSFC data provided by SWHJ and CARE were used to
estimate BSFC's for equipment with average horsepower of 8 hp and less, 8 hp to 20 hp and

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 flF which impedes its evaporation. Gasoline, on the other hand, has initial boiling
temperatures of 60 - 80 oF depending on (he season of year (RVP) and, therefore, evaporates
more readily.52 As a resuh, very little work has been done to quantify diesel refueling
emissions. Indeed, EPA is not aware of any studies of emissions from smiled diesei fuel.
However, woxk has been done by F. Peter Kutchins of the EPA to quantify displacement
emissions from diesel fuel.3* Hutchjns' worit has shown the displacement emissions from
diesel fuel to be 0.041 grams per gallon of fuel dispensed and fuel tank temperatures of
approximately SO °F. For (he purposes of die present study, all diesel equipment are
assumed to emit HC vapors at a rare of 0,041 grams per gallon of fuel dispensed. EPA is not
aware of any other data pertaining to refueling or evaporative emissions from dtesei fueled
equipment and, therefore, other diesel refueling emission sources are rot included in this
study.
Just as was needed for die gasoline refueling emission factors, the dieset refueling
emission factors were adjusted to be compatible wiih the populations and usage rates used in
the study. The units were changed from grams per gallon to grams oer horsepower hour

(except some recreational equipment which are expressed in g/hr and marine vessels which
are expressed in g/gal). To facilitate that change, assumptions regarding the brake specific
fuel consumption (BSFC) were necessary. Recognizing that dieseJ equipment generally have
lower BSFCs than gasoline equipment, the gasoline BSFC values were multiplied by 0-8 to
estimate BSFCs for diesel equipment54, Therefore, the BSFCs assumed in this report for
diesel equipment are 0.175, 0,12, and 0.063 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/hrt instead of gjhp-hr. The conversion was
made by multiplying the original value in g/hp-hr by the average horsepower and load factor
supplied by £EA.
3.4. Methodology Used to Calculate Evaporative EmisawD Jactors
This section will present the methodology and data used tq calculate evaporative
emission factors for gasoline and diesel equipment. Evaporative emissions are composed of
diurnal, hot soak, resting loss and cunning 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.31 * Both CARB and AP-42 refer to their work for diurnal emissions.
In summary, Southwest developed diurnal emission factors of 2 g/gal/day*1 and 4 g/gal/day
for protected (shaded) and unprotected fuel tanks, respectivelyt 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. Diurnal emission factors, in units of grams per day of possible use, are calculated
from the fuel tank volumes developed in section 3.2 of this appendix and are presented in
Table 1-15, Vessels wlOutboard Engines and Sailboat Auxiliary Outboard Engines are
assumed to have no diurnal emissions because fuel tanks for those equipment types arc not

Nnnroad BJnnne add Vehicle Emission Study
Hot Soak - After reviewing SAE papers and SwRI reports regarding evaporative
emissions and referring with several manufacturers, EPA found no appropriate values for hot
soak emission factors for nonroad engines. Hot soak emission values for on~highway engines
do exist, but dwy arc not representative of nonroad 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 the 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 nonmetallic 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%
isoociane, 30% toluene mixture (by volume). Assuming that the test fuel and regular gasoline
behave the same, the standard indicates the fuel container could lose 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 wa* 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, die&el
evaporative emissions are not included in this study. On a qualitative basis, however, it can
be said that evaporative emission* front dksel equipment should be much less than
evaporative emuslons from gasoline equipment because diesel fuel baa 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 of depending on die season of year (RVF) and,
therefore, evaporates more readily."

Chapter 4. Crankcas* Emission Factors
Crankcase emission factors are presented in this section for gasoline and diesel
nonroad equipment after a brief introduction of erankcase 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 me clearance between the piston and cylinder wail. Eventually, these gases
may escape from the crankcase to the atmosphere, hence, they are named crankcase emissions
and die crankcase is said to be open. Some manufacturers produce engines which route
crankcase 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,
AH gasoline 4-strofce equipment are assumed to have open crankcases except Lawn
and Garden Equipment (but not Chippersf Stump Grinders— ^»y are assumed 100% open),
Vessels wllnboard Engines and Vessels w/Sterndrive Engines, Only 21% of Lawn and
Garden Equipment are assumed open19 " and 100% of Vessels w/Inbwtrd Engines and
Vessels wiSterndrfve Engines axe assumed to have closed crankcases,
The rest of this chapter is separated into two sections. The first section introduces
crankcase emission factors for 4-9troke gflfioline fueled engines and the second introduces
crankcase emission factors foe 4-stroke diesel fueled engines, Crankcase emissions from 2-
stroke engines: do not exist due to the nature of 2-stroke engines, Thus, for equipment with
both 2-stroke and 4-stroke varieties, the crankcase emission factor is applied only to the 4-
stroke engines when calculating total emissions.

so, estimates for crankcase carbon monoxide (CO) or oxides of nitrogen (NOX) could not be
found. Therefore, those pollutants are not considered for gasoline nonioad crankcasc
emissions. The following paragraphs will present crankcase HC emission factors for gasoline
nonroad engines.
Probably the most widely accepted values for nonroad crankcasc HC emissions are
those found in AP-42.*0 AP-42 repons crankcase HC emissions for farm and construction
equipment based on work performed by Southwest Research institute (SwRI) in the early
L970's.61 The SwRI work on crankcase HC emissions suggests that "crankcase hydrocarbon
emissions are equivalent to about 20 percent of those in the exhaust . , ,"aj This
generalization is based on work performed by CharLw M. Heineri43 and P. A. Bennett, et
al** "" for on-highway vehicles. However, when calculating crankcase emissions, Hare
and Springer misinterpreted the Heinen report. Heinen actually proponed the value of 33% of
exhaust emissions (20% of total HC emissions) which was estimated by Fred W. Bowditch of
General Motors." Heinen chose Bowditch* s number as the best compromise of competing
values supplied by CARB (31% of uncontrolled HC exhaust; 20% of total)* the Federal
Government (49% of uncontrolled HC exhaust; 26% of lota])61 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 Bowditch (33% of uncontrolled
HC exhaust emissions and 20% of total emissions) appear to be educated estimates based on
General Motors "quality audit data"-

respectively. These 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.6" The EPA found that dw nine vehicles studied
emitted, on average, 1.92 grams of HC per mile (37.6 g/hr baaed 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 estimates of 4Z24 and 47.2 g/hr for tractor and nontractoi (aim equipment, respectively,
run over A steady state mode test. For puiposes of estimating total emissions from 4-stroke
gasoline nonroad engines, EPA accepts Bow ditch'3 value (33% of untreated exhaust) for all
gasoline engines with open crankcases. Four-stroke engines with closed crankcases and all 2-
g broke engines are assumed to have no crankcase emissions.
There may be concerns regarding the reliability of Bowditeh's crankcase number (33%
of uncontrolled HC exhaust) for use with today's nonroad engines. The relationship between
art-highway crankcase emissions and nonroad crankcase emissions has never been
documented for current year on-highway and nonroad engines. Differences in operating
cycles, machining tolerances* fuel delivery systems, etc., of cm-highway 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. 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 Report #460/3-84-011,** In addition, it is more conservative
than Bennett's number which has not been corroborated by other sources,

This section will present the beat available HC, CO, and NOX emission factor; for

hr),n The condition of the Caterpillar engine was not reported. For the purposes of EPA's
nonfood study, diesel crankcaa* HC emissions will be assumed to be 2 percent (the mean of
the range found by Hare and Bairtes) of untreated exhaust hydrocarbon emissions unless a
closed crankcase is implemented.
CO and NO* emissions from diesel crankcases have been reported by Hare and
Baines, and Caterpillar, Hare and Baines reported CO and NQX 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 NOX emission rates of 0,23 and 0.076 of
exhaust emission rates. For the purposes of EPA's nonroad study, CO and NOX crankcase
emissions from diesel engines will 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. In cases
where the crankcase is closed, EPA assumes zero diesel crankcase emissions.

Emisrioo Factor Development
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 coses to calculate emission rates as a
weight percentage of the total hydrocarbon emissions. Benzene exhaust emissions am
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 nonioad configurations (i.e., noncatalyst).TJ 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.1* 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).
FINAL - November 1991

Vchfcte Emiaaton Study
Chapter 6. 1,3-BitUdieiw
EPA has also chosen to express 1,3-butadiene emissions as a weight percent of tailpipe
exhaust hydrocarbons plus crankcase hydrocarbons. The respective percentages vised in this
study for nonroad diesel and gasoline engines are 1.6% and 1.3%-" Emissions of 1,3-
butadiene were almost never measured in engine exhaust prior to the late 1980'5, because tlw
procedures for doing so are relatively new. Only one study was available with measurement
from dteseJ engines, and one study with measurements from noncatalyst 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.
FINAL- November 1991

Emission Factor
Chapter 7, Nitrosamuies
In addition to HC, CO and NQ^ emissions, it has been documented that ru'trosamines,
which have been found to be carcinogenic in animals, are emitted from vented diesel
crankcases,™ While the contribution of motor vehicle emissions to the nitrosamine
concentration is not known for certain. Thomas M. Baines of EPA reportsTT (hat three
researchers (Gordon,™ Shapley7* and Pellizzari80) have identified nitrosamines near
roadways and two of the three suspected automobiles as a source. 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 nitroswnines contribote 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. Barnes for a more in depth analysis of
nitrosamines from diesel crankcase emissions and car interiors.
'** However, became of una;nainti« associated with the contribution of dtesd crank cases to nUTO3C*nine
cooMBtrabons, ioveototies for aitrwoMiiKsS were not developed.

Appendix K. Adjustments to Date in Developing Inventory A
In developing Inventory A, EPA made several adjustments ro annual hours of use,
load factor, population data, and the emissions inventory methodology for recreational marine
equipment that aie 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 commercial.
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,1 and GARB:3
Equipment Type
Lawnmowers (4-strake)
Lawnmowers (2-stroke)

2,17 (OPEI)
1,54 (OPEI)
1.8 (PPEMA)
2,5 (PPEMA)
1,5 (CARD)
These factors were calculated using the following general equation:
Adjustment Factor = (% consumer) x (consumer hrs) + (% commercial) x (commercial hrs)
In the case of trimmers/edgers/brush cutters, 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 blOwen/vacuums incorporates both

handheld and backpack versions. Detailed information used to derive these adjustments ace
contained in Appendix N, Part 2.
2, Load Factors
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,* and data supplied by EMI for
crawler tractors and rubber tired loaders/

Adjustment to Data in Developing Inventory
3. Populations—Chain Saws
In constructing Inventory A, EPA relied on a methodology developed by PPEMA" for
allocating chain saw populations to the local level. The methodology developed by EEA uses
single family housing units (SFHUs) and SIC 078 (landscaping and horticultural services)
employment. While this methodology is appropriate for most type* of lawn and garden
equipment, chain saws are not generally used in major urbanized areas except by horticultural
services. One of the four models proposed by PPEMA is based on urban population [human 1
outside major urbanized areas, rural area population, and SIC 078 employment, which is more
appropriate for allocating chain saw use. The national chain saw population estimates
reported by EEA were disaggregated to the local level using the local allocations developed
with this methodology for Inventory B, as follows:
NB local
N, local = —-——- x NA national
A NB national *
where N refers to the number of chain saws (all sizes) and A and B refer to Inventories A
and B.
4. Populations—Agricultural Equipment
For Inventory A, regional agricultural equipment populations were determined 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
i.
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. Thus, the census counts were used as indications to disaggregate the PSR
national population estimates to the local level.

As recommended by ISIA, EPA assumed that all snowmobiles use 2-scoke gasoline
engines, despite the fact that EEA reported a. very small number of 4-strokcs,
6. jtecreatiwial Marine Equipment Emissions Inventory Methodology
Population - Local boat registration data were used to establish the number of boats
of each equipment type in each nonattainment area- However, two adjustments to this
information were needed for inventory purposes. The first adjustment was to turn the number
of boats into the number of engines. This was necessary to match the horsepower and hours
of use estimates, which were derived per engine. The methodology used to calculate die
number of engines per boat for this study was developed by EEA and provided to EPA.
The second adjustment was to estimate the number of engines actually used in the
nonattainment areas. Unlike most of die equipment contained in this study recreational boats
are frequently transported long distances, such that where they are used may be different from
where they are owned. Survey tesults submitted by NMMA for eight nonattainment areas
were used as the basis for these adjustments. The survey was conducted for NMMA by Irwin
Broh and Associates, me, (IB&A).7 Questionnaires were mailed at random to registered boat
owners within and in counties lying within a 50-mile belt of the following nonanainment
areas;
Baltimore, MD Hartford, CT
Boston, MA Houston, TX
Chicago, IL Milwaukee, WI
Denver, CO Seattle, WA
The questionnaire asked a wide variety of questions about the kind of boat(s) owned;
engine number, type, and size; amount, location, and time of usage; and fuel used. The
-------
Adjustments to Data in Developing Inventory
information from the survey was used by EPA in the following formula to calculate the
umber of engines used in the nonattainment area:
EU = ER
PtielusedmD/a'atei + %
Fuel used by boils registered in n/a ana
flnm 0-1 mlto offshore
*n/a = nonattainment
where:
EU =± engines used in nonattainment area
ER = Engines registered in iKmartauunent area
Fuel used in n/a area - the sum of the repotted amount of fuel consumed
inside the nonatrainment area by boats registered inside die
nonattainment area, plus the fuel consumed within the nonattainment
area by boats registered outside the nonattainment area
Fuel used by boats registered in the n/a area - The total reported amount of
fuel consumed by boats registered inside the nonattainment area without
regard to where the fuel was consumed,
% use from 0-1 mile offshore =• The survey reported offshore use separately
from on-shore use. While offshore emissions have variable effects on
nonattainment area air quality, depending on meteorological conditions,
it would be inappropriate to totally ignore such emissions. Thus, boat
use within one mile offshore of nonattainment areas located on the
ocean or the Great Lakes was used as an approximation of the offshore
emission contribution. This contributed a relatively small fraction to
total boat usage in most nonattainment areas.
While the number of hours of use were also reported by the survey, fuel use was
chosen as a better representation of actual boat usage based upon NMMA's stated belief that
the reported fuel use was likely to be more accurate than the reported hours (NMMA was
concerned that the reported hours were the number of hours the boat was in the water, not the
number of hours the engine was being operated),
For the eight areas surveyed by IB&A. the actual survey results for each area were
used to calculate individual ratios of engines used to engines registered, For the other 16
areas, the average ratios from the eight surveyed areas were used. For all areas, separate
ratios were calculated for the five different equipment types in the recreational marine
category,
if *
-------
r* and VfcakJe^Emiariop Study
Because 16 of the areas were not surveyed, the average ratios determined from the
eight surveyed areas exceed reasonable maximum boat use in nonattainment areas with
relatively little water surface area. To account for this, a calculation of the maximum number
of boats that could be operated normally on the available water surface area was made for
each nonattainment area according to the following formula:
. . Water surface area in nonattumnent area
max. ooats = — —
Area required/boat
The water surface area in each nonattainment area was supplied by EEA. The ait a
required/boat was supplied by NMMA based on saturation limits determined for a joint study
by EPA and marine engine manufacturers in the early 197Q's (Grant No, R-801799), plus the
IB&A survey result* for types of boating activity,
NMMA supplied information suggesting that the available hours of prime boating use
an 384 hours/year (12 weeks/year, 4 days per week, 8 hours/day). This figure was multiplied
by the maximum number of boats to yield the maximum number of summer boat hours that
could be supported within each nonattainment area without hindering boat activity.
This theoretical maximum number of summer boat hours inside the nonattainment area
was compared to the amount of summer boat hours inside the nonattainment area calculated
from the survey results and the local boat registrations. The calculation of summer boat
hours from the survey and registration was made using the following formula:
Summer hours
jvm > -L. *—^ft- \\
ff n/i boat3)(bjQurs)
Fuel used in n/a
Pud used by boats registered in n/a area;

where:
i = each of the five equipment types in the recreational marine category
# n/a boats = # boats registered in the nonattainment area
hours = total annual hours of use per boat from the survey for boats registered
in the nonattainment area (includes hours operated outside the
nonattainment area)
FINAL
-------
Adjustment! to Data in Developing Inventory A
Fuel used ... = Both leans have the same meaning as defined, above, in the
formula, calculating engines used in nonattainment areas.
Summer usage = reported proportion of summertime operation from the survey.
In cases where the calculated summer boat hours exceeded the theoretical maximum,
the calculated number of engines used in the nonattainment area was reduced by the ratio of
the theoretical maximum summer boat hours to the calculated summer boat hours. Because
this correction ratio docs not include offshore boat use, the average offshore use was
subtracted prior to applying the correction ratio. For areas on the ocean or on a Great Lake,
the average of the offshore usage proportion for the five areas with offshore use was added
back after applying the correction ratio.
Annual Fuel U« Estimates - The load factor, horsepower, and regional hours of use
supplied by PSR were multiplied by the following BSFC estimates determined from test data
supplied by NMMA for recreational marine engines (the BSFC calculations are discussed in
Appendix I);
Diesel - 0,066 gallons/hr-hr
4-strokc gasoline - 0.1 gallons/hp-hr
2-stroke gasoline - 0,16 gailons/hp-hf
S«ason0l Adjustment Factors - Monthly usage reported by the survey respondents
were used to directly establish the proportion of boat usage in the summer and the winter for
six of the eight regions developed for mis study. For the two regions for which no areas
were surveyed, the southeast and the west coast, survey results from Houston were used.

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 exceedaitces 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 hour*; of
use and summertime and wintertime emissions.
1. Regional Adjustments
EPA has allocated the nonattainment anas studied to eight regions. Table L-Q1
indicates the nonattainment areas that fall into these eight regions, as well as the seasonal
designations for each region.
En constructing Inventory A, EPA used annual hcuis 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 dus region ait; determined by taking the average of the data fur
the Great Lakes and the Northwest regions.
This regional annual houn of use dau is documented in tt» Energy nod Envirotmenlal Analysis find report.

2. Seasonal Adjustment Factors
Because ozone and CO an largely summertime and wintertime problems, respectively,
seasonal adjustment factors were used to determine summertime VOC and NOX emissions and
wintertime CO emissions from nonioad engines and vehicles. Yearly emissions (tons per
year) were adjusted according to the following formulas;
tpsd - tpy x
tpwd = tpy x SAF,

seasonal adjustment factors (SAFs) are defined as follows;
_ . % activity during summer

This study did not consider day-to-day (e.g., weekend versus weekday) or hout-to-hour
activity level fluctuations. For most of the nomoad engines and vehicles studied, insufficient
survey data was available to estimate activity level variations at that level of temporal
resolution. Furthermore, ozone and CO excecdancea occur with reasonably similar frequency
on every day of the week, thus rendering suspect the value of emission inventories that make
Such distinctions.
The following chart shows the day-to-day distribution of ozone and CO nonattainment

and Springer reported construction seasons of 7, 8, and 9 months for the north.
central, and soathem regions, respectively. This corresponds to summer activity percentages
of 43%, 38%, and 33% in ihe same regions. The 1987 SIP emission inventories for Denver
and Atlanta reported wintertime activity percentages of 109fc and 20%, respectively. These
figures were applied to areas in the northern and southern regions. In this study, it was
estimated thai the wintertime activity percentage in the central region was 15%.
FINAL - November 1991
-------
Engine and Vehicle EmmiM Study
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
percemages 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 aH nonartainment areas to estimate wintertime agricultural
equipment activity.
Because of similarities in the growing seasons, summertime activity percentages for
lawn and garden equipment (excluding chain saws and snowblowers) were estimated to be the
same as those for agricultural equipment, CARS estimated in the Technical Support
Document for its proposed regulations applicable to lawn and garden equipment that
wintertime activity accounted for about 6% of yearly activity- This figure was applied to the
southern region, and the wintertime activity percentages in the central and northern regions
were estimated to be 3% and 0%. However, it was assumed dial all snowblower activity
occurs during die 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 studkd, only that for Chicago reported any nonunifoonity 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
uniformly distributed across the year.
Due to the year-round nature of equipment use, no seasonal adjustments were made to
activity for commercial marine vessels, airport service vehicles, logging equipment (including
all chain saws), or light commercial equipment, 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.
For recreational land-baaed equipment (e.g., off-highway motorcycles, ATVs,
mintbikes) other than snowmobiles, survey data submitted to EPA by the Motorcycle Industry

The following table* show the seasonal adjustment factors used for each equipment
type in each nonattaimncot area studied by EPA. To ease interpretation, they arc expressed
as SAFV Using this notation, tbe following percentages of annual use occurring during a
three month season would translate into the following factors:

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 act of summary tables, nonroad emissions are calculated using new engine
emission factors. In the second set of summary tables, nomoad emissions are calculated
using in-use emission factors.

Appendix N. EPA Use of Manufacturer Data In Inventor; 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 are detailed below. Part 1
is a general overview of the data supplied by manufacturers and used by EPA in constructing
Inventory B. Part 2 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 arc listed in Table N-01. Estimates of average engine-
rated horsepower, annual use, and load factors 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," EMFs cotton picker estimates
were only considered in areas where the populations were higher man the Inventory A
estimate 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 estimates
from EMI in developing Inventory B. These included swamers ("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.
Additional adjustments to EMI data are detailed below in Part 2.

1.2. Outdoor Power Equipment Institute, Inc. (OPEI)
OPEI provided data on nonhandheld equipment types shown below in Table N-02.
EPA combined OPEI's separate estimates for lawn tractors and garden tractors to replace the
data for lawn and garden tractors from Inventory A.
OPEI supplied test data which were used to calculate load factors for lawnmowers,
rear engine riding mowers, front mowers, and lawn and garden tractors. For other equipment
types, 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

1.4. Industrial Truck Association (ITA)
ITA provided load factor, annual hours of use, and CMSA-level population estimates
for industrial foridifts, 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)
Population Data — Local boat registrations were used to establish the number of
boats of each equipment type owned in each nonattainment area, as was done for
Inventory A. The same method was also used to calculate the number of engines from the
number of boats. However, NMMA requested that the adjustment for the number of engines
actually used in the nonattainment areas be handled differently than was done for
Inventory A. Rather than directly rely on the ratio of the reported fuel consumed in the
nonattainment areas to the reported fuel used by boats registered in the nonattainment area
from the IB&A survey, NMMA requested that the adjustment be handled by a formula based
upon the water surface area per registered boat in the nonattainment area.
The formula was derived from the relationship between water surface area per
registered boat and the reported ratio of fuel consumed in the nonattainment areas to the fuel
consumed by boats registered in the nonattainment area for the eight surveyed areas.
Equations of the form Y = 1 - exp)"*1" provided the best fit to the data, where
Y = ratio of fuel used in the nonattainment area (from boats registered both inside
and outside the nonattainment area) to total fuel used by boats registered in
nonattainment area (includes fuel used outside the nonattainment area)
X = local water surface area/registered boat in nonattainment area
k and m are coefficients
N-4 FINAL - November 1991
-------
EPA Use of Manufacturer Data In Inventory B
The value of m was used to calibrate the formula such that the highest i2 values were
obtained without yielding larger values for y in any nonattainment area than the ratio of the
theoretical maximum number of summer boat hours inside a nonattainment area to the total
summer hours of use calculated for boats registered in a nonattainment area. This ratio was
calculated as follows:

The definition of the above terms and the derivation of this formula are discussed in
Appendix K, Section 6.
The value of k was determined by the regression. The final formula developed was:
Y = 1 - exp'238*'**68
This formula was used to develop the basic ratio of fuel used in the nonattainment
area to total fuel used by boats registered in the nonattainment area for each of the 24 areas.
For those areas located on the ocean or the Great Lakes, the proportion of use within 1 mile
offshore reported by the survey for the five areas on the ocean or a Great Lake were added to
the basic ratio. The final ratio was multiplied by the number of engines registered in the
nonattainment area to calculate the number of engines used in the nonattainment area.
Fuel Use — For the eight surveyed areas, the average fuel use per engine reported in
the survey for boats registered in the nonattainment area were used in the inventory
calculations. For the nonsurveyed areas, NMMA submitted a national average fuel use
estimate for outboard motors of 91 gallons/year. This estimate was based on the amount of
2-stroke marine motor oil consumed each year. The average fuel use reported in the survey
for outboard motors was 142 gallons/year. NMMA requested that EPA use the
91 gallons/year estimate for outboard motors for all of the unsurveyed areas, and scale the

average fiiel use reported by the survey for the other equipment types by the outboard motor
factor, i.e., 91/142.
Seasonal Adjustment Factors — As was done for Inventory A, the proportion of boat
use in the summer and the winter was based on monthly usage reported by the survey
respondents,
1.7. Motorcycle Industry Council, Inc. (MIC)
MIC provided EPA with survey information on the number of miles ridden annually
by ATVs and off-highway motorcycles.* An average speed of 25 miles per hour was
assumed in order to convert these figures into hours per year. MIC also provided national
population figures, which were distributed to the local level using the ratio of the local to
national population estimate for Inventory A. The same distribution between 2-stroke and 4-
stroke versions as reported by EEA was used in developing Inventory B.
2. Detailed Adjustments
2.1. Equipment Manufacturers Institute (EMI)
EMI supplied load factor, horsepower, annual hours of use, national and CMSA-lcvcl
population data for various types of construction equipment. The data supplied and the
adjustments made to the data are detailed below.

Crawler Tractor 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

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.
For wheel loaders EMI supplied national population, horsepower,
and load factor, as well as CMSA level populations and
hours/year, EPA estimated national hours of use by population
weighting regional values over 23 nonattainment areas.
For scrapers, EMI supplied data as for rubber tired loaders.
For motor graders, EMI supplied data as for rubber tired loaders.
For dumpers (off-road haulers), EMI supplied data as for rubber
tired loaders.
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 uniform 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.
EMI supplied data for backhoe loaders as for rubber tired
loaders.
EMI supplied data for skid steer loaders as for rubber tired
loaders.
EMI supplied data for log skidders as for rubber tired loaders,
except that national populations were not provided.

EMI supplied only estimates of the national population, average

EMI supplied data for rough terrain forklifts as for trenchers,
EMI supplied data for cotton pickers as for robber tired loaders.
EMI supplied local population and annual use estimates for
square balers and bale wagons, as well as national data for
horsepower and load factor. To estimate national hours per year
for both versions individually, EPA weighted regional values
over all 24 areas. EPA estimated aggregated hours per year for
all balers at the regional level by population weighting regional
values. At the national level, EPA estimated aggregated hours
per year, horsepower, and load factor by weighting regional
values by population, (population) (hours/year) and (population)
(hours/year) (horsepower), respectively.
EMI supplied only horsepower and load factor data for mobile
work platforms.
In the draft version of this study, data submitted by EMI for combines and agricultural
tractors was used to construct Inventory B. This included population figures developed by the
U.S. Bureau of the Census, which EMI has stated may include seldom-used equipment.
However, EMI has cautioned that, in constructing an emission inventory, appropriate
corrections should be made to either the operative population estimate or the estimate of
average annual usage. EMTs submitted data contained no such correction. Consequently, the
final version of Inventory B uses the same data as Inventory A for these two types of
equipment.

2.2. OPEI Data
Population Data — CMSA population data for lawnmowers, riding mowers, lawn
tractors, garden tractors and tillers were supplied by OPEf. 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.

EPA Use of Manufacturer Data la Inventory B
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:
40,000 lawn tractors x 41 krs
+ 29,326 garden tractors x 56 firs _ 4?« .
40,000 + 29,326 ™
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 18% of all tillers are used
commercially and that 82% are used by consumers. Commercially used tillers are assumed to
operate 4 times as much as consumer tillers. Thus, the local consumer hours of use reported
by OPEI for each area was multiplied by 1.54 to obtain overaE hours of use, as follows:
0.82 x (f consumer hours)
+0.18 x (* consumer hours x 4) = (J J4) (# consumer
(.82 * (.18 x 4) (f consumer hours)
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 they are used
commercially while "Rear Engine Riding Mowers" are not.
Lawnmowers
Hours of use for lawnmowers are also weighted by commercial and consumer populations as
well as 2-stroke and 4-stroke populations. Based upon sales, useful life, and usage
information supplied by OPEI, 94.8% of all lawnmowers are consumer and 5.3% are

commercial, with commercial mowers operating 16 times as much as consumer mowers. Of
the consumer lawnmowers, 90% are 4-stroke and 10% are 2-stroke. Of the commercial
lawnmowers, 85% are 4-stroke and 15% are 2-stroke. Thus, the local consumer hours
reported by OPEI for each area was multiplied by 2.17 to obtain overall average hours of use
for 2-stroke lawnmowers, as follows:
0.948 x 0.10 x (# consumer hours)
+0,053 x 0.15 x (16 x # consumer hours) ,~ ,_~ ,„ ,
(094g „ ftm>« (0.0,; x 0.,5) ' «•"»> 9 consumer hour,)
Similarly, the local consumer hours reported by OPEI for each area was multiplied by 1.75 to
obtain overall average hours of use for 4-stroke lawnmowers, as follows:

Data for weighting the horsepowers by usage was not available.
Load Factor Data - In a letter to EPA dated September 9, 1991, OPEI discussed the
fact that some types of lawn and garden equipment are fitted with a governor that prevents
the engine from reach the RPM at which the rated power (as advertised) is measured. One
means of accounting for this discrepancy between the rated and governed maximum power is

EPA Use of Manufacturer Data In Inventory I
to decrease the applicable load factor. Based on data included in this letter, the following
load factors were calculated for use in Inventory B:
Lawnmowers - 30%
Rear engine riding mowers - 38%
Front mowers - 38%
Lawn and garden tractors - 38%
In all odter cases, the load factors for lawn and garden equipment used in Inventory B
were the same as those used in Inventory A.
2.3. PPEMA Data
Population data — Population data were taken from a Heiden report1 for 2-stroke
gasoline 'Trimrners/TBdgers/Brush Cutters"**, "Leaf Blowers/Vacuums", "Chain Saws
< 4 hp", and "Chain Saws > 4 hp". In an earlier version of this report, Heiden proposed a
methodology that relied on urban single family housing units (SFHUs), rural SFHUs, and
SIC 078 (landscaping and horticulture services) employment. However, because the
regression coefficient for urban SFHUs was negative in the case of chain saws and blowers,
Heiden developed on additional model that relies on urban population [human] outside major
urbanized areas, rural population, and SIC 078 employment. For these two types of
equipment, this additional methodology was used to construct Inventory B. For trimmers, the
original methodology proposed by Heiden was used, as no other model was clearly superior
on either an econometric or intuitive basis.
The PPEMA chain saw population was distributed to over and under 4 hp ranges
based on the distribution reported by EEA.

Usage Data — Usage data for hand blowers, back blowers, trimmers/brush cutters,
hedgetrimmers, chain saws and cut off saws for commercial (professional) and consumer were
supplied by PPEMA in an earlier Heiden report .ft That data was population weighted to
obtain average annual hours of use values for "Trimrners/Edgers/Brush Cutters", "Leaf
Blowers/Vacuums", "Chain Saws < 4 hp" and "Chain Saws > 4 hp". National population data
were provided in the October 30, 1991 Heiden report (see Population Data above),

Appendix O. Emission Inventory B
Inventory B 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.

Transport and Nooroad Enussioos
Chart P-01. The ROMNET Region and the Northeast Corridor.
FINAL - November 1991
-------
Nooroad Engine and Vehicle Emission Study
To determine the ozone-fonning potential of the emission inventory under "real-world" +
conditions, the model incorporated meteorological data from actual historical ozone episodes. *J
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 "
NOX and VCC 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 NOX emission by 57% from the 2005
baseline level. The CAA version would reduce VOC emission by 32% and NOX 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
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
F4' FINAL - November 1991
-------
Transport and Nonroad Emissions
figures, the effect of reducing 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 miles 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 die
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 NOX 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 NOX 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 in 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
methanol (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 NOX. Neither
measure alone could reduce emissions enough to bring the Corridor into attainment.

According to the ROMNET report, "The results suggest that without stringent upwind
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 die 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 NOX 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/N

Nonroad Engine and Vehicle Emission Study
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 NOX 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.

Nooroad Engine and Vehicle Emission Study
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 eastem 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
exceedancc is the fact that Grand Rapids, a much larger and more heavily industrialized city
than Muskegon approximately SO 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 eastem 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 quantity 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.

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
FINAL - November 1991
-------
Nonroad Engine and Vehicle Emission Study
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
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,* 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-ll, 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.

3. Transport Conclusions
An analysis of ROMNET study finds the following:
I, Transport from all 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 NOX 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 remaining
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 die 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 dean 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
working with the Northeast transport commission required by the Clean Air Act to help them
develop strategies for attainment. These regional models will continue to use existing
national emission inventories, which, as discussed above, have some shortcomings in the area
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.

Q-2
FINAL - November 1991
-------
Response to Public Comment
1.1. Recreational Marine Equipment
For the October draft of the nonioad study, EPA relied heavily on data supplied by
NMMA from a survey conducted by Irwin Broh and Associates (ffi&A) in eight
nonattainment areas. The results from this survey were used to adjust local boat registration
data to represent actual usage in the nonattainment area (Inventories A and B), determine
seasonal adjustment factors (Inventories A and B), and calculate annual hours of use, average
horsepower, and load factors for Inventory B.
In comments on the October draft of this report, NMMA requested the following
technical revisions be made to activity levels:
1. Use an alternative methodology to determine boat usage based on the concept
of "saturation boating".
2. A methodology to extend the saturation boating concept to the 16 unsurveyed
areas.
3. Use fuel based activity levels (i.e., gallons/year) and emission factors (i.e.,
grams/gallon), rather than using horsepower-hour based factors.
4. Use national average fuel usage estimates, based upon the sales of a unique oil
formulation used to mix with 2-stroke outboard motor fuel.
5. Correct an error in the calculation of average fuel usage from the survey.
EPA made the following adjustments in response to NMMA's comments:
1. and 2. - Saturation boating methodologies - For Inventory B, a new methodology
was developed for the 8 surveyed areas based upon the concept of saturation boating and
extended to the 16 unsurveyed areas. Specific equations for allocating boat populations using
the concept of saturation boating were developed separately by EPA and NMMA. The
equation developed by NMMA was:
F = 0.7 [1 - exp (-630A)]
where:
F = fuel used in the nonattainment area as a fraction of the total fuel used by
boats registered in the nonattainment area
A = water surface area available for boating in the nonattainment area divided
by the number of registered boats in the nonattainment area.
FINAL - November 1991
-------
Nonroad Engine and Vehicle Emission Study
The equation developed by EPA was slightly different:
Overall, both formulas yielded similar results (the average ratio for all 24 areas was
39% using NMMA's formula and 39.5% using EPA's). EPA's formula was used in
developing Inventory B for the following reasons:
EPA's formula yielded better r2 values when regressed against the reported
usage ratios from the 8 surveyed areas (32 vs. .26 for NMMA's formula).
EPA's formula generated ratios closer to the calculated saturation limits for
those areas with high boat densities per nonattainment area water surface area.
NMMA's formula capped me ratio at a maximum of 70%, which may not be
appropriate for areas with very low boat densities per water surface area
(although only one of the nonattainment areas studied, Provo-Orem, falls into
this category)
NMMA's actual equation was not submitted until November 7, 1991 (the
concept was proposed several weeks earlier).
NMMA specifically requested that this methodology be used for Inventory A, as well
as Inventory B. However, EPA was reluctant to totally ignore the survey results from the
IB&A survey. Instead, a compromise methodology was used for Inventory A. The IB&A
results were used to estimate boat usage in each nonattainment area. This estimate was then
compared to the calculated maximum summertime usage based upon saturation boating. In
cases where the survey results yielded higher ratios than the calculated saturation ratio, die
local estimates were adjusted downward to match the calculated saturation limits. A more
complete description of the methodology is contained in Appendix K.
3. Fuel-based activity levels - As recommended by NMMA, both Inventory A and
Inventory B were revised from horsepower-hour based calculations to fuel use. Descriptions
of how this was done are contained in Appendix I (for emission factors), K (for Inventory A
fuel use), and N (for Inventory B fuel use).
4. National average fuel use estimates - The national annual average of 91 gallons
per outboard powered boat calculated by NMMA was used for the 16 unsurveyed areas for
_ FINAL - November 1991
-------
Response to Public Comment
Inventory B. The fuel usage for the other recreational marine equipment types was also
adjusted for these areas using the outboard ratio of 91 gallons per year to the reported survey
results of 142 gallons per year (Le,, 91/142). No adjustments were made to the reported
survey results for the eight surveyed areas, or to any areas for Inventory A (fuel usage for
Inventory A is based upon information supplied by PSR and BSFC calculations from data
supplied by NMMA, not upon LB&A survey results).
5. Error in fuel usage calculations - The error reported by NMMA in calculation
of fuel usage from the IB&A survey was corrected and Ac results recalculated. This
primarily affected the calculation of the proportion of boat use in the nonattainment areas for
Inventory A (lowering the calculated number of boats used in the nonattainment areas by
about 15%).
1.2. Lawn and Garden Equipment
EPA received numerous comments from OPEI and PPEMA. The following comments
were all incorporated into Inventory B and, as noted, into Inventory A.
1. Annual hours of use adjustments for commercial use - OPEI commented that
the splits between consumer and commercial populations they had supplied for the draft
report were erroneously reported as population splits instead of sales splits. The correction
roughly halved the commercial populations, with the following impact on the multiplicative
adjustments to consumer annual hours of use to reflect the much higher annual usage of
commercial equipment:
Draft Final
Lawnmower (2-stroke) x2.5 x2.17
Lawnmower (4-stroke) x2.5 xl.75
Tiller x2.2 xi.54
These corrections apply to both Inventory A and Inventory B.
2. Load factors for lawn and garden tractors - OPEI pointed out that load factor
adjustments based upon their letter of September 9, 1991 from John F. Linskey to Clare Ryan
of EPA had not been incorporated into the draft. This has been corrected in the final report.
FINAL - November 1991
-------
Nonroad Engine and Vehicle Emission Study
dropping the Inventory B load factors from ,47 to .38 for lawn and garden tractors, rear
engine mowers and front mowers,
3. Horsepower estimates - OPEI commented that errors had been made in their
submittal of horsepower ranges for lawn and garden tractors and that 2-stroke snowblowers
are smaller than 4-stroke. Based upon new data supplied by OPEI, Inventory B horsepower
estimates for lawn and garden tractors dropped from 15.4 to 13.32 and 2-stroke snowblowers
from 5.1 to 3.75.
4, Local disaggregation of handheld equipment population - While PPEMA had
previously submitted population estimates for hand-held equipment (i.e., chain saws, blowers,
trimmers/edgers), for the October draft this equipment was disaggregated to the local level
using the general lawn and garden methodology developed for Inventory A. PPEMA
subsequently developed a population disaggregation model for hand-held equipment using
state-level shipment data and rural, suburban, and urban population splits. PPEMA used this
method to directly calculate local equipment populations for chain saws, blowers, and
trimmer/edgers. These local population estimates have been incorporated into Inventory B.
In addition, as chain saws have very different usage patterns from most lawn and garden
equipment (i.e., virtually no individual use by urban residents), the methodology developed by
PPEMA was also used to disaggregate local chain saw populations for Inventory A.
EPA received two comments specifically relating to lawn and garden activity levels
that have not been incorporated into the final report. First, OPEI commented that the
population data for tillers in Inventory A was about 40% higher than in Inventory 1, and
asked that Inventory A be reduced. Although OPEI certainly knows how many tillers their
members sell each year, this is not the same as knowing the population. Engine useful life,
annual hours of use, scrappage rates, and consumer/commercial splits all affect equipment
populations. PSR uses different methods of estimating populations than OPEI. In most cases,
PSR and OPEI generated similar population estimates. There is no available information
identifying one population estimate as being clearly superior to the other. Thus, using one
method for Inventory A and the other for Inventory B is the most equitable solution.
The second comment that was not incorporated was on tiller load factors. Briggs and
Stratton submitted information on the load cycle of several types of equipment. Most of this
information either supported the CARB estimates or has been incorporated into Inventory B
6 FINAL - November
-------
Response to Public Comment
load factors. The exception was tiller load factors, CARB estimated a load factor of 40% for
tillers. The data submitted by Briggs and Stratton was interpreted to yield a load factor of
only 20%. However, the dynamometer test used to determine the load on die engine
indicated that the engine used .24 gallon/hour to generate only 0.6-0.7 horsepower. This
equates to a BSFC of .34-.4 gallons/horsepower-hour, far higher than expected for these
engines. A tiller engine using .24 gallons/hour should generate at least twice this amount of
power; which would be in line with a 40% load factor.
1.3. Recreational Equipment
ISIA commented that there are no 4-stroke gasoline snowmobile engines in operation
in the United States. In response to this comment, the final report assumes that all
snowmobiles use 2-stroke gasoline engines for both Inventory A and Inventory B, despite the
fact that EPA contractors reported a very small number of 4-stroke engines,
1.4. Industrial Equipment
The hours of use for forklifts used in the draft report for Inventory B were based on a
statement by ITA in its comments concerning the workshop held by EPA on April 3-4, 1991,
"A typical light-duty forklift truck may be run for 40 hours per week for an average of
2000 hours per year." In its response to the draft report, ITA commented that by "typical" it
did not mean average, and stated that 850 hours is the correct average use rate. EPA adjusted
the hours of use for forklifts in Inventory B to 850 hours for the filial report.
1.5. Agricultural Equipment
EMI submitted data for combines and agricultural tractors which was used in the draft
version of mis study to construct Inventory B. This data included population figures
developed by the U.S. Bureau of Census, which EMI has stated may include seldom-used
equipment. EMI has cautioned mat, in constructing an emission inventory, appropriate
corrections should be made to either the operative population estimate or the estimate of
average annual usage. EMTs submitted data contained no such correction. In comment on
the draft version of this study, EMI stated that the Inventory B results for agricultural
equipment are significantly overstated because EPA did not apply the downward adjustments
FINAL November 1991
-------
Nooroad Engine and Vehicle Emission Study
needed. As EPA docs not have any information on how to apply such downward
adjustments, EPA has used the same data for Inventory B as used for Inventory A for these
two types of equipment in this final report.
1.6. Construction Equipment
Payhauler commented that the draft report contains large distortions in the construction
equipment/mining category populations in nonattainment areas, in large part as a result of
difficulties arising from the use of product sales and/or industry statistical information in
estimating equipment populations. Payhauler listed a number of factors which could increase
the possibility of error, including confused product descriptions in the sales record, products
are frequently short term rental fleets and moved around the country, and the county of sale is
not likely to be the county or even state of use.
No adjustments were made to the final report in response to Pay hauler's comments for
two reasons. First, EPA does not have any data on which to base such adjustments, nor did
Payhauler provide any data. Second, product sales were used in this report only to establish
state or national level populations. These populations were disaggregated to the local level
using local construction activity indices. Thus, the local population figures should reflect the
movement of products around the country to actual jobsites.
2. Emission Factors
EPA received comments from several industry associations, including OPEI, NMMA,
EMA, PPEMA, and IT A, regarding the emission factors used in the study. One of the
common concerns among the industry associations was related to the development and use of
adjustment factors which were applied to new engine emission factors to estimate in-use
emission rates. The associations were especially concerned with the limited data mat were
used to develop the adjustment factors for the equipment categories they represented and
suggested that in-use factors should not be applied until more data is collected.
EPA realizes that the in-use adjustment factors are based on limited data and could be
improved when additional in-use engine testing is completed. However, the in-use
adjustments are EPA's best estimates based on existing data, and are clearly superior to the
default of zero in-use deterioration, which would result if no in-use factors were applied. In
FINAL - November 1991
-------
jtespoose to Public Comment
addition, the inventories in this study are presented two ways, with the in-use adjustment
factor applied, and also without the in-use factor applied. This is done by the use of stacked
bar charts which readily show the additional contribution of emissions from the in-use
adjustment estimates.
The in-use adjustment factors for 2-stroke outboard motors in the draft study report
were adjusted downward to 1.2 for HC and CO (from 1.5 for HC and 1.3 for CO) for the
final study report. This is discussed in greater detail in Section 2.2.3. of Appendix I. While
the arguments presented by NMMA were persuasive as to the superior durability and
maintenance of outboard engines, such that these in-use adjustments were made for the final
report, they did not support a total lack of in-use engine wear and malmaimenance.
Other comments regarding emission factors were more specific to certain equipment
types. OPEE was concerned that the emission factors for snowblowers and commercial turf
care equipment should be revised to better represent the horsepower ranges of these
equipment. Upon review of the emission factors in the draft study, EPA agreed that these
factors warranted adjustment. For snowblowers, the emission factors used for lawn mowers
were used for the final study report. For commercial turf care equipment, the emission
factors for lawn and garden tractors were used.
OPEI also presented sales data on the proportion of utility engines sold over the last 8
years with open and closed crankcases. Based on this data, the crankcase emission factors for
lawn and garden equipment were revised to reflect 22% open crankcases (the draft report
assumed 100% open crankcases).
EMA expressed concern that the paniculate emission factors used in the draft study
report were outdated. The emission factors were derived from AP-42 and based on 1973 tests
performed at Southwest Research Institute. EMA suggested that the test results from a recent
joint EPA/Industry program to assess test cycles for nonroad equipment be used to revise the
paniculate emission factors as well as NOX, HC, and CO emission factors. The paniculate
emissions from the four 1991 diesel nonroad engines tested suggest that these newer engines
have considerably lower paniculate emission rates than the emission factors reported in AP-
42. To reflect this concern, the paniculate emission factors used for Inventory B are the
equally weighted average of the AP-42 emission factors and the 1991 EPA/Industry average
8-mode nonroad engine test data. However, because there is no way to determine when
HNAL November 1991
-------
Nonroad Ensnne tod Vehicle Emission Study
diesel engines began to emit lower amounts of participates, the paniculate emission factors
for Inventory A remain those reported in AP-42. A more complete discussion of this is
contained in Section 1.2.1. of Appendix I.
Another main area of concern for EMA related to the adjustment factor used to
convert from steady state emission factors to in-use (transient) emission factors. EMA
suggested that the adjustment factor should be corrected to a value halfway between the
steady state and cm-highway transient values instead of a correction all the way to the on-
highway transient, as was done in the draft study report. However, although the transient
cycle used to simulate highway heavy-duty engine operation may not be as appropriate to
simulate nonroad equipment transient operation, EPA expects that it is a better representation
of nonroad equipment that encounters transient operation in use than the 8 -mode steady state
test (it should also be noted that no adjustments were made for equipment types expected to
primarily, but not exclusively, encounter steady state operation). EPA realizes that different
equipment types have varying degrees of transient and/or steady state operating characteristics
in-use. However, it was beyond the scope of this study to characterize the in-use operating
cycles of the numerous equipment types included in the study. Therefore, the final study
report continues to reflect the on-highway transient adjustment for those equipment types
expected to encounter transient operation in use and no adjustment for those equipment types
expected to primarily encounter steady state operation.
3. Additional Con™JM*ationa/Qtber
This section summarizes comments received that were not directly related to activity
levels or emission factors,
3.1. Use of Equipment Categories
EPA received comments from EMI and NMMA requesting clarification of EPA's use
of equipment categories in constructing emission inventories. Both were concerned that the
categories used for this study could be construed as potential regulatory categories.
EPA considered over 80 different types of equipment in this report, many of which are
highly specialized and have low sales volumes. EPA grouped the equipment types into 10
FINAL - November 1991
-------
Response to Public Comment
equipment categories only to assist the disaggregation of national or state equipment
populations to the local level, and to ease analysis and reporting of inventory results. EPA
has revised the final report to clarify that these categories are not intended to represent
potential regulatory categories.
3.2. Inclusion of Two Sets of Inventories
EPA received a request for clarification of the use of two inventories from EMI, and
two manufacturer associations expressed concern about data on which Inventory A is based,
IT A expressed concern about lack of access to PSR data and methodology and uncertainty
about what is included in Inventory A populations. EMI expressed concern about the method
used in Inventory A of estimating equipment populations using engine shipment data,
PSR is a commercially available marketing research data base, and the EEA
methodology is based on publicly available indices of commercial activity. Although several
manufacturers expressed their belief that PSR was not accurately estimating equipment sales,
in every case where manufacturers were willing to divulge equipment sales data to PSR or
EEA (12 cases total), PSR's estimates showed excellent agreement with the equipment sales
data (usually within 5%). In addition, much of the data used in Inventory A was not
available from any other source.
EPA also developed a second set of inventories, Inventory B, which relies on
manufacturer-provided data for almost all high usage equipment types. This industry-
provided data might not be publicly available to states, but does give EPA a valuable cross
check for the first set of inventories. In general, EPA regards both inventories as being
equally appropriate estimates of nonroad populations and activity rates, and has learned a
great deal from the ways in which they differ and agree.
3.3. Transportable Equipment
EMA commented that EPA should include all transportable equipment (e.g.. generator
sets, compressors, pumps), as well as self propelled, in the nonroad emissions inventory. It is
EMA's position that both fall exclusively within the scope of nonroad mobile engines and
vehicles, and that both are within the scope of EPA's authority under Tide II of the Clean Air
Act. EMA states further that EPA can only make a determination to regulate engines used in
FINAL-November 1991 ' ' »,
-------
Nonroad Engine and Vehicle Emission Study
transportable equipment based on the nonroad study, and that by falling to include all
transportable equipment in the study, EPA has failed to meet the mandate imposed on it by
Congress.
There were several types of equipment that are not included in this study due to lack
of data, not just transportable equipment. For example, mining equipment also is not
included in the study. Transportable equipment below SO hp are included in the study, but
transportable equipment over SO hp are not due to lack of data and potential conflict with
stationary source requirements.
EPA does not agree that the exclusion of equipment types from the study either
prohibits EPA from regulating such equipment as nonroad engines or violates the mandate
imposed by Congress. Congress required EPA to regulate nonroad engines if nonroad
emissions are determined to be significant based on this study. However, this is a one-way
requirement; it does not forbid EPA from regulating nonroad engines under other
circumstances. Further, while Congress mandated that the determination of significance be
made for nonroad engines as a whole based on this study, the regulatory requirements are for
EPA to ". . . promulgate (and from time to time revise) regulations containing standards
applicable to emissions from those classes or categories of new nonroad engines and new
nonroad vehicles (other than locomotives or engines used in locomotives) which in the
Administrator's judgement cause, or contribute to, such air pollutants." Nothing in this
language restricts EPA to only those classes or categories included in this study or prohibits
EPA from updating the assessment of emission contributions in the future.
3.4. 2-Stroke Marine VOC Emission Reactivity
NMMA submitted the claim that VOC emissions from 2-stroke marine engines are
less photochemically reactive than other forms of VOC emissions. However, NMMA did not
submit any data substantiating this claim.
VOC reactivity is a very complicated process. While an important consideration is
ozone formation, the reactive processes are far from completely understood. Thus, EPA does
not have sufficient information to judge the validity of NMMA's claim. Without data
substantiating the overall reactivity of unbumed fuel, EPA must use the standard assumption
that the VOC reactivity of motor vehicle emissions are relatively similar.
CH2 FINAL - November 1991
-------
Response to Public^Comment
3,5. Conclusion! Chapter
NMMA commented that the nonroad study is a technical report and, as conclusions
are best left for the regulatory process, suggested that EPA remove Chapter 5 from the report.
The purpose of the conclusion chapter is to highlight major points and to identify the
points that EPA considers to be most important. No part in the conclusions is intended to be
other than a summary of the data presented in the report. Thus, EPA does not agree that it
should be removed.
3.6. Consideration of Updated Information
NMMA requested that EPA make a clear statement in the report recognizing the
possibility that improved data may result in changes to the inventories, and that such data, if
available and credible, will be used by EPA in the determination of significance and any
subsequent regulatory process.
Updated data will not necessarily be used in the determination of significance; nor will
it be arbitrarily excluded. However, EPA agrees with the statement that any subsequent
regulatory activity will incorporate new information. While EPA does not believe this
statement needs to be in the body of the report, it is acknowledged here.
3.7. Transport
In their comments, NMMA and OMC brought up several issues that complicate the
estimation of the impact of transported VOC emissions on urban nonattaJnment, For
example, NMMA submitted a report compiled by Sierra Research questioning the impact of
VOC emissions on ozone transport. EPA does not necessarily agree with all of these
comments, however, the issues raised do illustrate the complex nature of transport, and the
difficulty of estimating precisely the impact of relatively distant emission sources on any
particular nonattainment area. EPA did not include estimates of the impact of transported
emissions on urban nonattainment in the final quantitative inventory estimates in recognition
of such difficulties. Reliable quantitative estimates of the impact of transported emissions
from marine pleasure craft may become available as existing photochemical models such as
the Regional Oxidant Model (ROM) and the Urban Airshed Model (UAM) are further refined
and applied to individual nonattainment areas in the next several years. EPA is not

attempting to prejudge these results in this report, but merely intends to note that transported
ozone or ozone precursors caused by marine pleasure craft used in rural areas and other rural
sources may have an impact on urban air quality. The principal conclusions of the impact of
all nonroad sources on urban nonattainment contained in this report are based solely on
emissions inside the nonattainment areas studied.
In its comments, EMI asserts that transport from more rural areas to urban areas
cannot be considered to contribute to urban nonattainment because the concentration of ozone
and ozone precursors is generally lower in rural areas. EMI states: The common-sense
observation is that if 'Air Mass B' moves into an airshed, then *Air Mass A', the air already
there, has to be moved." To this observation, EPA would add a second observation: that air
is not a solid. Elementary principles of physics and meteorology would imply that as Air
Mass B enters an area, it mixes with Air Mass A, and that (assuming atmospheric pressure
remains constant) some of this mixture exits the area. To the extent that Air Mass B contains
air with lower concentrations of ozone and ozone precursors than Air Mass A, this mixing
will lower the concentration of ozone in the urban area. However, the effectiveness of this
mixing in lowering the concentration of ozone in the urban area is dependent on the
concentration of ozone and ozone precursors in the entering Air Mass B, and not merely on
the fact that this concentration may be lower than the concentration in the preexisting Ak
Mass A.
To illustrate this principle, let us assume first that Air Mass B contains no ozone or
ozone precursors. Clearly, men, the concentration of ozone and ozone precursors in the
mixture of Air Mass A and Air Mass B would be much lower than the concentration in Ak
Mass A before it was diluted. On the other hand, we could consider a case where Ak
Mass B has concentrations of ozone and ozone precursors that are only slightly lower than
those concentrations in Ak Mass A. Under this scenario, the concentrations of ozone and
ozone precursors in the mixture would be nearly the same as those concentrations in the
urban Ak Mass A. Thus, emissions of ozone precursors into a rural ak mass can have a
deleterious impact on urban ak quality by reducing the ability of prevailing winds from rural
areas to dilute the pollution in urban ak.
These conclusions were borne out by the EPA study entitled "Regional Oxidant
Modeling for Northeast Transport", or "ROMNET". This study was based on a detailed

Response to Public Comment
photochemical air quality model (the Regional Oxidant Model or ROM) for the northeastern
quadrant of the U.S. EMI has urged elsewhere in their comments that EPA apply this ROM
model to the study of emissions from nonroad sources specifically. ROMNET traced the
formation of ozone levels in the major northeastern urban areas during specific ozone
episodes by incorporating detailed information on emissions and meteorological conditions
prevailing during those episodes. The ROMNET study incorporated emissions from nonroad
sources along with all other sources of ozone precursors. The study was specifically designed
to determine if transport from the western, generally rural part of the ROMNET region (e.g.,
Ohio, western Pennsylvania) had a negative impact on air quality in the major coastal urban
areas (e.g., Philadelphia) during conditions that were known to have produced an actual
exceedance of the ozone standard. The study concluded that this transport did, in fact,
contribute to nonattainment of the ozone standard in the coastal areas, despite the fact that
actual levels of ozone and ozone precursors in an air "packet" as it passed over the more
western areas were considerably lower than the levels of ozone and ozone precursors in that
air "packet" as it passed through the coastal urban areas.
Elsewhere in the Clean Air Act, Congress apparently concurred with the conclusion
that emissions in rural areas can contribute to urban nonattainment. In Section 184 of the
Clean Air Act, Congress explicitly created an Ozone Transport Commission comprising 11
northeastern states and the District of Columbia. Congress had concluded that the transport
of ozone and ozone precursors in this region was so significant mat the air pollution control
policies of these states should be coordinated to insure their fairness and effectiveness.
Included by law in the Ozone Transport Commission is the State of Vermont, a rural state
with no ozone nonattainment areas.
3.8. Determination of Significance/Air Quality Analysis
EMI suggested mat the October draft does not provide sufficient information for a
determination of significance. EMI believes that:
"In order to meet the requirements of Section 213(aX2) the CAA with respect
to a determination of significance, an air quality analysis which takes into
account heterogeneity in the geographical distribution of nonroad engines/
vehicles, seasonal factors, transport and other atmospheric variables, and which
includes photochemical modeling, is required."

Nontoad Engine and Vehicle Emission Study
As EMI discusses at some length in their comments, EPA does not base the
contribution of nonroad engines to ambient air quality problems on photochemical air quality
modelling in this study. EPA reiterates its previous position that photochemical modelling is
not required to draw valid scientific conclusions about the contribution of nonroad emissions
to nonattainment, and that Congress did not intend to require EPA to construct such models.
In the nonroad study, EPA has assumed that the contribution of nonroad sources to the
concentration of ozone during a nonattainment episode is proportional to the contribution of
nonroad sources to the total amount of VOCs and NOX emitted in that area by all sources.
This is the approach that has historically been taken by EPA in determining the contributions
of different sources to nonattainment and in estimating the general effectiveness of nationwide
air pollution control measures. It is based on the widely accepted scientific position that
urban ozone is formed by the reaction of VOCs and NOX in the presence of sunlight.
Congress in no way indicated that it intended for EPA to digress from mis approach; in fact,
the legislative history of the CAA clearly shows that Congress conceived of the relative
significance of nonroad sources in terms of their contribution to the total inventory of VOCs
and NOX. The Senate Committee Report notes that "[e]missions inventories from EPA
estimate that farm and construction equipment emit 3.7 percent of CO nationwide, 4 percent
of nationwide NOX, and 1.3 percent of total hydrocarbons." The Senate Report further states
"While inventories of these emissions are not precise, estimates indicate the extent to which
they contribute to ozone and other pollution problems." (Senate Report No. 101-228, p. 104)
Clearly, the intended mandate of Section 213 is that EPA improve upon existing emissions
inventories for nonroad sources and mat a conclusion about the significance of nonroad
sources could be based on these inventories.
Further, in placing a one-year deadline for die completion of the nonroad study, and
an additional one-year deadline for issuing standards based on the results of the study,
Congress indicated a certain urgency in addressing this long-neglected category of pollution
sources. The one-year deadline is one of only a very few specific requirements for
performing the nonroad study; in general, EPA was not told how to perform the study, but
rather to complete it quickly. This deadline effectively precludes the time-consuming
development of photochemical models. The Regional Oxidant Model for Northeast Transport
(ROMNET) study, which covers only the Northeast quadrant of the U.S., took over five years

to complete. An Urban Airshed Model of the Lake Michigan area is also expected to take
several years to produce results. Due to the time and expense required to develop
photochemical models, Congress has required only states with serious, severe, and extreme
nonattainment areas to include them in their State Implementation Plans for attainment of the
ozone standard. These areas were given 4 years to complete State Implementation Plans;
areas that were not required to include photochemical models were required by Congress to
submit State Implementation Plans in 3 years (CAA Section 182).
Finally, it is quite possible that Urban Airshed or Regional Oxidant Modelling would
not offer any significant increase in our understanding of die significance of nonroad sources
to the nationwide urban nonattainment problem. These models were developed primarily to
help individual nonattainment areas determine die effectiveness of specific air pollution
control measures, given highly detailed data and assumptions for the unique conditions
prevailing in that area. Thus, the models could be used to assess whether a given proposal
for reducing emissions from a type of nonroad source would be more effective in a given area
than some other measure. However, emission control measures have not yet been proposed
for any nonroad source and Congress mandated that the nonroad emission study assess the
impact of current inventories before EPA issued any such proposals.
