Purpose 

This report documents the basic evaporative emission assumptions and calculations used 

in EPA’s final NONROAD2008a emissions model. The types of evaporative emissions covered 

in this report include diurnal, tank permeation, hose permeation, hot soak, and running losses. 

Separate reports address displacement and spillage from refueling (NR-013b) and crankcase 

emissions (NR-010f). Relative to the December 2005 version of this report, this version has 

been updated to incorporate the standards in the 2008 final rulemaking affecting small nonroad 

SI engines and equipment, as well as marine SI engines and vessels. [1] It also describes updates 

to some of the pre-control emission rates, as well as the new ability of NONROAD2008a to 

specifically model the effects of ethanol blends on fuel tank and hose permeation losses. 

Introduction 

Evaporative emissions refer to hydrocarbons released into the atmosphere when gasoline, 

or other volatile fuels, evaporate from equipment. The types of evaporative emissions are 

defined below, along with a discussion of the changes since the draft NONROAD2004 model: 

- diurnal: These emissions are due to temperature changes throughout the day. As the day gets 

warmer, the fuel in the tank heats up and begins to evaporate. Diurnal emissions were included 

in draft NONROAD2004, but the methodology has been updated for final NONROAD2005. In 

addition, final NONROAD2005 includes diffusion losses (vapor exiting an orifice regardless of 

changes in temperature) as part of diurnal emissions. NONROAD2008a incorporates diurnal 

controls for marine SI engines, places limits on diffusion losses for small SI engines, and no 

longer models diffusion losses for handheld engines. 

- permeation: These emissions are due to fuel that works its way through the material used in the 

fuel system. The outer surfaces of these materials are exposed to ambient air, so the gasoline 

molecules permeate through these fuel-system components and are emitted directly into the air. 

Permeation is most common through plastic fuel tanks and rubber hoses. Fuel and tank 

permeation were not included in draft NONROAD2004, but have been developed for final 

NONROAD2005 in conjunction with rulemaking development for spark-ignition (SI) engines. 

NONROAD2008a incorporates hose and fuel permeation controls for small SI and marine SI 

engines, updates some pre-control emission factors for hose permeation, and includes updated 

hose lengths for outboard boats.

- hot soak: These emissions are due to residual heat from the equipment just after the engine is 

shut off. There were placeholders for this emission type in draft NONROAD2004, which were 

set to null (zero) values. Final NONROAD2005 has estimates for hot soak emissions. There 

have been no changes for NONROAD2008a. 

- running loss: These emissions are similar to diurnal except the heating is caused by engine 

operation. Like hot soak, there were placeholders for this emission type in draft 

NONROAD2004, which were set to null (zero) values. Final NONROAD2005 has estimates for 

running loss emissions, including controls for large SI engines. NONROAD2008a includes 

running loss controls for small SI nonhandheld equipment. 

- displacement: These emissions are the vapors displaced from the fuel tank when the tank is 

refueled. These emissions are included in both draft NONROAD2004 and all subsequent 

versions, including NONROAD2008a. They are discussed in another technical report (NR013b). 

- spillage: This refers to fuel spilled during refueling events. Like displacement, these emissions 

are included in both draft NONROAD2004 and all subsequent versions, including 

NONROAD2008a. They are discussed in another technical report (NR-013b). 

- crankcase: These are vapors released from the crankcase of an engine. These emissions are 

included in both draft NONROAD2004 and all subsequent versions, including 

NONROAD2008a. They are discussed in another technical report (NR-010f). 

- resting loss: Resting losses occur when the equipment is not being used. The ambient 

temperature is either stable or declining during a resting loss event. These losses are mainly due 

to permeation and diffusion emissions. There were placeholders for this emission type in draft 

NONROAD2004, which were set to null (zero) values. Final NONROAD2005 and 

NONROAD2008a do not have a separate entry for resting loss emissions, since they are already 

included as part of the permeation and diurnal emissions. 

Equipment fueled with compressed natural gas (CNG), liquified petroleum gas (LPG), 

and diesel fuel are assumed to have no significant evaporative emissions. As a result, all 

evaporative emissions calculated by the model are from gasoline-fueled equipment. 

Evaporative Emission Standards 

In addition to estimating emissions from uncontrolled engines, the NONROAD model is 

designed to account for the effect of federal emissions standards. NONROAD will not cover 

California emission standards or proposed federal standards that are not yet final. 

NONROAD2008a accounts for evaporative standards established under the following 

regulations: 

2
 
•	 “Control of Emissions From Nonroad Large Spark-Ignition Engines and Recreational 

Engines (Marine and Land-Based).” This rule establishes evaporative standards for large 

spark-ignition engines greater than 25 horsepower (hp) and recreational vehicles. 

Recreational vehicles include snowmobiles, all-terrain vehicles, and offroad motorcycles. 

[2] 

•	 “Control of Emissions From Nonroad Spark-Ignition Engines and Equipment.” This rule 

establishes evaporative standards for small spark-ignition engines less than or equal to 25 

hp and marine SI engines. [1] 

The emission standards with the affected model years for each category are summarized 

in Table 1.

a The evaporative standards apply to gasoline-fueled equipment. Equipment fueled with compressed natural gas (CNG), liquefied 

petroleum gas (LPG), and diesel fuel are assumed to have no significant evaporative emissions.

b Recreational vehicles include snowmobiles, all-terrain vehicles, and offroad motorcycles. For the marine SI category, portable 

tanks are used by outboard engines ≤25hp. Other installed tanks are assigned to outboard engines >25hp and all 

inboard/sterndrive engines.
 c In some instances, the standards are phased-in over time. The rulemakings should be consulted for details. The nonhandheld
 

hose permeation standard begins in the 2009 model year (MY), but is modeled with a 95% phase-in beginning in 2008, based on
 

manufacturers’ use of low permeation hoses in that timeframe.

d Standards for the large SI gasoline category and running loss emission source are expressed as a percent reduction from
 

uncontrolled engines. The permeation standards must be met at specified temperatures, using gasoline with 10 percent ethanol
 

(E10).
 e Although there are no diurnal emission control standards for small SI engines, control of diffusion emissions is modeled
 

beginning with the 2012 MY for Class I and the 2011 MY for Class II nonhandheld engines. NONROAD2008a also assumes no
 

diffusion emissions for handheld equipment.

f No permeation control is modeled for handheld equipment used in cold weather applications (i.e., chainsaws).

Evaporative technology types have been used beginning with NONROAD2005 to define 

unique sets of standards. These technology types are specified for each SCC, hp category, and 

model year. The evaporative technology types take the following form: 

12345678 

E00000000 

where: 

E: Evap tech type 

1: Diurnal 

2: Tank permeation 

3: Hose permeation 

4: Hot soak 

5: Displacement 

6: Spillage 

7: Running loss 

8: Resting loss (not used) 

and Value: 

0: Base 

1: Control Level 1 

N: Control Level N 

For example, the base case (pre-control) technology type is E00000000. For a model year 

containing the first tier of both diurnal and running loss controls, the corresponding technology 

type would be E10000010. There is only one tier of evaporative controls, so the control value is 

1 for most technology types; however, it has been necessary to add technology types with control 

values of 2 and 3 in some cases as a way to account for standard phase-in schedules. 

The resulting technology distributions by SCC, hp category, and model year are provided 

in Appendix A, Table A1. 

Diurnal Emissions 

Methodology and Baseline Diurnal Estimates 

For diurnal emission estimates, the Wade equations [3,4,5] are used to calculate grams of 

hydrocarbons emitted per day. The Wade equations are well established and are also used in the 

MOBILE model. The Wade equations are provided in Appendix B. These equations require the 

following inputs: percent tank fill, percent headspace, tank size, Reid Vapor Pressure (RVP) of 

the fuel, the minimum temperature (Tmin), and the maximum temperature (Tmax). The percent 

headspace assumed and hard coded in the model is 15 percent. The percent tank fill assumed and 

hard coded in the model is 50 percent. The tank sizes are provided in the spillage input file. 

5
 
Documentation of the tank sizes used in the NONROAD model is provided in the technical 

report for refueling emissions. [6] RVP, Tmin, and Tmax are user inputs. 

With this approach, diurnal emissions during the winter could be overestimated, 

especially using non-weathered fuel RVPs. To account for this, winter diurnal emissions are 

adjusted by including a minimum temperature of 40°F, below which diurnal emissions are set to 

zero. The model checks both Tmin and Tmax to see if either one is below 40°F. If both are 

below 40°F, then diurnal emissions are zero. If just Tmin is below 40°F, but Tmax is above 

40°F, Tmin is adjusted to 40°F. For example, if Tmin is 20°F and Tmax is 50°F, the model 

calculates diurnal emissions for just the 40°F to 50°F range. 

For on-highway applications, a correction of 0.78 is applied based on a comparison of 

automotive test results to the theoretical Wade equations. Based on nonroad data, this correction 

appears to be appropriate for nonroad applications as well. Appendix C provides a comparison 

of nonroad test data to the theoretical Wade equations. As a result, a correction of 0.78 is applied 

for all gasoline equipment. This correction factor is hard coded in the model. 

We also account for diffusion losses in the baseline diurnal emissions for tanks that have 

open vents directly to the atmosphere. Diffusion refers to the rate at which hydrocarbon 

molecules flow out of a small orifice in the fuel tank due to molecular motion in the fuel tank. 

This rate is equivalent to the rate at which the hydrocarbon molecules would collide with a wall 

area equal to the size of the hole and will occur at constant, or even decreasing, temperatures. 

For fuel tanks that have a sealed system with pressure relief (i.e., personal water craft) we 

would not expect to see diffusion losses. In addition, data presented in Appendix C show that, 

when the fuel tank is vented through a long hose, diffusion is minimal. This is probably due to 

additional molecular collisions created by the hose. For this reason, we do not model diffusion 

losses for systems that have a long vent hose (i.e., installed marine fuel tanks). We also do not 

model diffusion losses for recreational equipment. Finally, we believe that handheld equipment 

are all produced with either sealed fuel tanks or slosh/spill resistant fuel caps. Therefore, for 

NONROAD2008a, we do not include diffusion emissions for handheld equipment. 

We model diffusion losses for large SI equipment, small SI nonhandheld equipment, and 

portable marine fuel tanks which have open orifices that vent directly to the atmosphere. For 

marine equipment, outboards less than or equal to 25 hp are considered to have portable fuel 

tanks in NONROAD2008a. In these applications, the vents are typically in the fuel cap. To 

model these losses, we draw on diurnal emissions data for a fuel tank with and without a vent 

line. Based on these data, we see about 40-50% higher emissions over a diurnal test for a tank 

with a small vent directly to the atmosphere than for a tank that is vented through a hose. In our 

modeling, we use a correction factor of 1.46. The data and derivation of this correction factor is 

provided in Appendix C. This correction factor or multiplier is contained in the evdiu.emf input 

file. 

6
 
 

Additional diurnal adjustments are applied for recreational marine equipment. These 

include: 1) temperature swing adjustments, 2) a 50 percent baseline reduction for boats with 

portable plastic tanks, and 3) a 70 percent baseline reduction for personal watercraft to account 

for the presence of 1 psi pressure relief valves. Each adjustment is discussed below. 

For recreational marine equipment, fuel temperature swings are generally not as large as 

the associated ambient temperature swings. This is especially true for boats stored in the water. 

Recreational marine equipment can be classified as boats with installed plastic or metal tanks 

which are stored on trailers, boats with installed plastic or metal tanks which are stored in the 

water, and boats with portable plastic tanks. For boats with installed plastic or metal tanks which 

are stored on trailers, the diurnal temperature swing is reduced by 50 percent, resulting in revised 

Tmin and Tmax values that are then used to calculate diurnal emissions. For boats with installed 

plastic or metal tanks that are stored in the water, the diurnal temperature swing is reduced by 80 

percent. For boats with portable plastic tanks, we treat portable tanks as exposed to ambient air; 

as a result, there is no temperature swing adjustment. The data used to derive these estimates are 

presented in Appendix C. These temperature swing adjustments are hard coded within the 

model. The fractions of equipment falling into each category by SCC and hp are provided in the 

spillage.emf input file. We treat the smallest installed tanks as being on trailer boats and the 

largest tanks as being on boats stored in the water. For sizes in between, we use a linear 

interpolation of the fraction of boats stored in the water. Based on this analysis, 5 percent of 

personal watercraft and 35 percent of boats with installed fuel tanks are stored in the water. 

An example of how the model calculates revised Tmin and Tmax values to account for a 

reduced temperature swing is provided here for illustration. Example: For Tmin =60°F and 

Tmax = 84°F, calculate revised values given a 50 percent temperature swing reduction. 

1) Temperature swing = (84°F-60°F) = 24°F 

2) New temperature swing with 50% reduction = 0.5x24°F = 12°F 

3) Average diurnal temperature = (84°F+60°F)/2 = 72°F 

4) The new temperature swing is applied to the average diurnal temperature to calculate revised 

Tmin and Tmax values. 

Revised Tmin = 72°F-6°F = 66°F; Revised Tmax = 72°F+6°F = 78°F 

Most, if not all, recreational marine portable fuel tanks have valves that the user can close 

when the boat is not in use. For the purpose of modeling, we estimate these valves are closed 

half the time based on the assumption that user behavior is highly variable. Therefore, for 

outboards ≤ 25hp, which have portable fuel tanks, an additional diurnal adjustment of 0.50 is 

applied. This correction factor or multiplier is contained in the evdiu.emf input file. 

Personal watercraft (PWC) have sealed systems with pressure relief valves that range 

from 0.5 to 4.0 psi. These tanks are modeled as having a 1 psi pressure relief valve, and only 

emit vapor when the pressure calculated by the Wade equations exceeds 1 psi. To account for 

this, a simplified additional diurnal adjustment of 0.30 is applied for PWC, which is based on a 

7
 
comparison of estimated annual diurnal emissions with and without the relief valves, using 

regional daily RVP values. The data used as the basis for this estimate is provided in Appendix 

C. This correction factor or multiplier is also contained in the evdiu.emf input file. The use of a 

single correction factor is a limitation, in that seasonal changes in temperature and fuel RVP are 

not reflected. On an annual basis, however, the difference should be minimal. 

Installed fuel tanks are vented to the atmosphere through a hose running from the tank to 

the outside of the hull. In NONROAD, installed fuel tanks are considered to be used in 

outboards > 25 hp and all inboard engines. No additional baseline diurnal adjustments beyond 

those discussed above are applied for installed fuel tanks. 

Deterioration factors for diurnal emissions are contained in the evdiu.det input file. There 

is no deterioration applied to diurnal emissions in NONROAD2005, so the deterioration factor is 

1. 

Diurnal Controls 

Diurnal control (i.e., 90% reduction) is applied for large SI gasoline equipment, beginning 

in the 2007 model year (MY). Controlled large SI gasoline equipment will be primarily 

pressurized to 3.5 psi. Therefore, the diffusion should be zero and diurnal emissions minimal. 

To model diurnal control, a diurnal adjustment (multiplier) of 0.10 is applied for these 

equipment. 

Although there are no diurnal emission requirements for small nonroad SI equipment, a 

limit was placed on diffusion emissions, beginning with the 2012 MY for Class I and the 2011 

MY for Class II nonhandheld engines. This reduces the diurnal multiplier from 1.46 to 1.0 for 

these engines. Note that we do not include diffusion emissions for handheld equipment (i.e., the 

multiplier is 1.0 for all years). 

For marine SI engines, we model portable fuel tanks as having 90 percent lower diurnal 

emissions than an open vent system to account for use of automatic seals beginning with the 

2010 MY. Also, we set the diffusion multiplier to 1.0 because the tanks would be sealed. 

Presumably, the diurnal temperature cycles would build some pressure in the fuel tank causing 

hydrocarbons to be released when the tank is opened. Therefore, we do not model these tanks as 

having zero diurnal emissions. For PWC, we use the baseline scenario of sealed systems with a 

1.0 psi pressure relief valve. For installed fuel tanks, we model a 60 percent reduction starting in 

the 2011 MY to account for the use of carbon canisters in the fuel line with passive purge. [7] 

As in the baseline, no diffusion is modeled for PWC and installed fuel tanks. 

These control adjustments, along with the baseline adjustments described above for 

diffusion losses, recreational marine equipment with portable fuel tanks, and PWC, are applied 

via the evdiu.emf emission factor input file. The evdiu.emf emission factor input file is provided 

in Appendix A, Table A2. The portion of the spillage file which contains the tank capacities is 

provided in Appendix A, Table A3. 

8
 
The only fuel correction factor for diurnal emissions in the NONROAD model is for 

RVP. The effect of ethanol fuels on diurnal breathing loss emissions must be estimated with the 

RVP input. In areas with no RVP waiver, no adjustment is required to the RVP inputs. In areas 

where ethanol receives a 1 psi waiver, areas must estimate the fraction of market fraction of 

ethanol use, and input a weighted average RVP. For example, in an area with a 1 psi waiver 

where the market fraction of ethanol is 25% and the RVP of the base gasoline without ethanol is 

7.8 RVP, the inputted weighted average RVP should be 0.25* (7.8+1) + 0.75 * (7.8) = 8.05. 

There is no additional RVP adjustment in the model for commingling or fuel weathering effects. 

Diurnal Sample Calculation 

A sample calculation is provided for recreational marine inboard engines. Calendar year 

2011 is chosen, which is also the first model year for which diurnal controls apply for this 

category. To account for the mix of pre-control and control engines in 2011, diurnal calculations 

are performed separately for the pre-2011 MY and the 2011 MY engines present in the 2011 

calendar year. These are then summed to obtain total diurnal emissions for 2011.

(from by-model-year output file) 

Calculations: 

1) The diurnal temperature swing is reduced by 50% for the fraction of tanks installed in 

vessels stored out of the water. The diurnal temperature swing is reduced by 80% for 

installed tanks in vessels stored in the water. Calculate new Tmin and Tmax values for 

50% and 80% temperature swing reductions. 

Diurnal avg T = (60°F +84°F)/2 = 72°F 

9
 
Temperature swing = (84°F -60°F) = 24°F 

New temperature swing with 50% reduction = 0.5*24°F =12°F 

New Tmin = 72°F -6°F = 66°F; New Tmax = 72°F +6°F = 78°F 

New temperature swing with 80% reduction = 0.2*24°F =4.8°F 

New Tmin = 72°F -2.4°F = 69.6°F; New Tmax = 72°F +2.4°F = 74.4°F 

2) Using the Wade equations in Appendix B, along with the new Tmin and Tmax from 1), 

Diurnal EF with 50% temp swing reduction = 19.645 g/day 

Diurnal EF with 80% temp swing reduction = 7.731 g/day 

3) Apply 0.78 correction factor and appropriate Wade equation multiplier. 

Pre-2011 MY engines: 

Adjusted diurnal EF with 50% temp swing reduction = 19.645*0.78*1.0 = 15.323 g/day 

Adjusted diurnal EF with 80% temp swing reduction = 7.731*0.78 *1.0 = 6.030 g/day 

2011 MY engines: 

Adjusted diurnal EF with 50% temp swing reduction = 19.645*0.78*0.4 = 6.129 g/day 

Adjusted diurnal EF with 80% temp swing reduction = 7.731*0.78 *0.4 = 2.412 g/day 

4) Calculate weighted diurnal g/day emissions 

Pre-2011: (0.469*15.323)+(0.201*6.030)+(0.231*15.323)+(0.099*6.030) = 12.535 g/day 

2011 MY: (0.469*6.129)+(0.201*2.412)+(0.231*6.129)+(0.099*2.412) = 5.014 g/day 

5) Calculate tons/day 

Pre-2011 MY: (12.535 g/day)*(308,139)*(1b/453.6g)*(ton/2000 lb) = 4.258 tons/day 

2011 MY: (5.014 g/day)*(17,391)*(1b/453.6g)*(ton/2000 lb) = 0.096 tons/day 

Total: 4.258 tons/day + 0.096 tons/day = 4.354 tons/day 

6) Calculate tons/year
 

2011 is not a leap year, so it has 365 days.
 

Total: 4.354 tons/day * 365 days/year = 1,589 tons/year
 

Tank Permeation 

Fuel tank permeation is estimated with the following general equation: 

Tank permeation (g/day) = tank permeation emission factor (g/m2

/day)*fuel tank inside surface 

area (m2

)*TCF*(1-metal fraction)*DF 

where: 

TCF = temperature correction factor 

DF = deterioration factor 

10
 
The TCF is calculated using the average temperature for the scenario. Thus, the inputs 

needed to estimate tank permeation emissions are the tank permeation emission factor, the 

surface area of the fuel tank, the average ambient temperature, the tank metal fraction, and the 

deterioration factor. 

Metal tanks are assumed to have zero permeation, so the metal fraction is not included in 

the calculation of emissions. 

The model has the capability of including deterioration, but no deterioration is assumed 

for tank permeation (i.e., all DFs equal to 1.0). The DFs are contained in the evtank.det file. 

The spillage.emf input file contains tank capacities in gallons. As a result, it was 

necessary to develop a relationship to convert tank capacity (gallons) to surface area (m2

) in order 

to apply the above equation. Both EPA and ARB measured the fuel tank surface areas of a 

number of different fuel tanks of various volumes from different applications. These data are 

provided in Appendix D. A hyperbolic expression was developed to fit through the volume and 

surface area data. This expression, which is hard coded in the model, is shown below: 

surface area (m2) = 0.15*SQRT((((gal+2)^2)/4)-1) 

This equation is used with the fuel tank capacities in the spillage.emf file to estimate fuel tank 

surface area by equipment type. 

Because permeation is very sensitive to temperature, we used Arrhenius’ relationship [8] 

to adjust the emission factors by temperature, where the constants were determined by relating 

the equation to the known properties of materials used in fuel tanks and hoses. Generally, 

permeation roughly doubles with every 10°C increase in temperature for materials used in fuel 

systems, such as high density polyethylene (HDPE) and nitrile rubber. 

The temperature adjustment is applied from the average temperature for the scenario. 

Since the emission factors are based on a temperature of 85°F, the temperature adjustment 

therefore reduces emissions by 50% with each 10°C reduction from 85°F. The temperature 

adjustment is calculated using the following equation: 

Tank TCF = 3.788519E-2*exp(3.850818E-2*Tavg) 

where Tavg = average temperature, °F 

The equation is a curve fit to the equation: TCF = 0.5*exp((29.4°C - X°C)/10). The temperature 

adjustment is hard coded in the model. 

NONROAD2008a also has the ability to model the effects of ethanol-gasoline blends on 

both tank and hose permeation emissions. To do this, emission factors using gasoline (E0) and a 

11
 
 

10 percent ethanol blend (E10) are required. The ratios of E10 to E0 emission factors are input 

to equations that predict permeation emissions for ethanol volume percents specified by the user. 

These equations are hard coded in the model. A section describing this methodology in more 

detail, along with a sample calculation for an ethanol blend fuel, are provided following the hose 

permeation section. 

The sections immediately below discuss the tank permeation emission factors (on 

gasoline and E10) and tank metal fractions used for each of the following nonroad categories: 

small SI, large SI, recreational marine, and recreational equipment. A sample calculation for 

gasoline is then presented. The evtank.emf emission factor input file is provided in Appendix A, 

Table A6. The metal fractions are in the spillage.emf file, provided in Appendix A, Table A3. 

Small SI Tank Permeation 

Fuel tank permeation rates were developed by CARB and EPA for a number of different 

uncontrolled tanks for both handheld and nonhandheld equipment. The data and results for 

gasoline are shown in Appendix E. The data for E10 can be found in documentation for the 2008 

rulemaking. [7,9] Based on a review of the data, it is reasonable to break the tanks into three 

categories, HDPE tanks below 0.25 gallons, HDPE tanks above 0.25 gallons, and nylon handheld 

fuel tanks. The average baseline tank permeation emission factors are shown below: 

Table 2. Small SI Tank Permeation Baseline Emission Factors at 29°C (g/m2

/day) 

Tank Type Gasoline (E0) E10 E10/E0 

Metal tanks 0 0 0 

Nylon handheld fuel tanks* 1.25 2.5 2.0 

Small SI HDPE <0.25 gallons 6.5 7.2 1.1 

Small SI HDPE ≥0.25 gallons 9.7 10.7 1.1 

* Nylon is used in equipment with structurally-integrated fuel tanks, which are primarily chainsaws. 

The nylon EFs are therefore assigned to chainsaws in the model. 

In previous versions of NONROAD, nylon handheld fuel tanks were modeled by 

applying an adjustment to the HDPE emission factors to account for the nylon fraction of the 

tanks. These adjustments are no longer used in NONROAD2008a; instead, the nylon-specific 

emission factors in Table 2 are used. 

There is a small SI tank permeation standard of 1.5 g/m2/day. The implementation 

schedule is dependent on the engine subcategory. We believe that fuel tanks using alternative 

materials to meet the 1.5 g/m2

/day standard on 10 percent ethanol fuel will typically permeate at 

least 50 percent less when gasoline is used. Therefore, we model permeation from fuel tanks 

meeting the standard to be 0.75 g/gal/day at 29°C on gasoline. The exception is that no 

permeation control is modeled for chainsaws, since they are used in cold weather applications. 

The small SI control tank permeation emission factors used in the model are shown in Table 3.

The resulting gasoline baseline and control emission factors are contained in the evtank input 

file. The E10/E0 adjustment factors for the baseline emission factors are contained in the 

spillage.emf file and provided in Appendix A, Table A5. The E10/E0 adjustment factor of 2.0 

for the control emission factors is hard coded in the model. 

The tank metal fractions are based on sales data and conversations with manufacturers. 

Metal fractions are 0.2 for Class 1, 0.1 for Class 2, and 0.0 for Classes 3-5. Class 1 are 

nonhandheld engines <225cc, which corresponds to 3-6hp. Class 2 are nonhandheld engines 

>=225cc, which corresponds to 6-25hp. Class 3 are handheld engines <20cc, which corresponds 

to 0-1hp. The descriptions of Classes 4 and 5 are provided above. The tank metal fractions are 

contained in the spillage.emf file. 

Large SI Tank Permeation 

Most of the large SI engines run on LPG and have metal tanks. For the remaining 

gasoline-fueled engines, the majority of these also have metal tanks. There are a few examples 

of applications with plastic tanks (e.g., concrete saws, utility vehicles), but these represent a 

small fraction of the total. For modeling purposes, all large SI equipment are assumed to have 

metal tanks, so there are no tank permeation emissions from large SI gasoline equipment in 

NONROAD2008a. 

Recreational Marine Tank Permeation 

Fuel tanks may be constructed in several ways. Portable fuel tanks and some small, 

higher production-volume, installed tanks are generally blow-molded using high-density 

polyethylene (HDPE). Installed plastic marine fuel tanks are often produced in many shapes and 

sizes to fit the needs of specific boat designs. These fuel tanks are generally rotationally-molded 

out of cross-link polyethylene. 

Separate baseline emission factors were developed for HDPE and cross-link tanks used in 

recreational marine vessels. These emission factors are provided in Table 4 below. The data and 

derivation of the E0 emission factors is provided in Appendix E. The data for E10 can be found 

in documentation for the 2008 rulemaking. [7,9]

Metal tanks 0 0 0 

HDPE plastic tanks 9.9 10.9 1.1 

Cross-link plastic tanks 8.0 8.8 1.1 

These emission factors were then assigned to each SCC and hp category. Outboard 

engines <=25hp, PWC, and inboard/sterndrive engines <=16hp were assigned the HDPE 

emission factor. Outboard engines >25hp and inboard/sterndrive engines >16hp were assigned 

the crosslink emission factor. 

A standard of 1.5 g/m2

/day is applied, beginning in the 2011 model year for PWC and 

outboard engines ≤25 hp and the 2012 model year for outboard engines >25 hp and all 

inboard/sterndrive engines. Similarly to small SI, we model permeation from fuel tanks subject 

to control to be 0.75 g/gal/day at 29°C on gasoline. The recreational marine control tank 

permeation emission factors used in the model are shown in Table 5.

Metal tanks 0 0 0 

HDPE plastic tanks 0.75 1.5 2.0

The resulting gasoline baseline and control emission factors are contained in the evtank input 

file. The E10/E0 adjustment factors for the baseline emission factors are contained in the 

spillage.emf file. The E10/E0 adjustment factor of 2.0 for the control emission factors is hard 

coded in the model. 

The metal fraction is zero for outboards <=25hp and all PWC. The metal fraction for 

outboards >25hp and all inboard/sterndrive engines is 0.33. 

Recreational Equipment Tank Permeation 

A baseline emission factor of 9.7 g/m2

/day is used for all recreational equipment. This is 

the same emission factor used for small SI equipment with tanks equal or greater than 0.25 

gallon. A standard of 1.5 g/m2

/day is applied, beginning in the 2008 model year. In 

NONROAD, a control emission factor of 0.75 g/m2/day is used for the 2008 and later model 

years. This is based on a 50 percent compliance margin to account for E10 fuel effects. The 

model does not yet account for any ethanol blend permeation effects for this category. 

Recreational equipment are assumed to have no metal tanks (i.e., metal fraction = 0.0).

Tank Permeation Sample Calculation 

A sample calculation is provided for small SI equipment operated on gasoline. 

User Inputs: SCC: 2265006015 (4-stroke air compressors) 

MaxHP: 6 

Tavg: 75°F 

Calendar year: 2005 

Model Inputs: EF: 9.7 g/m2/day at 85°F (evtank.emf) 

Tank size: 1.1 gal (spillage.emf) 

Tank metal fraction: 0.2 (spillage.emf) 

DF: 1 (evtank.det) 

Engine population in 2005: 65,329 (model output) 

Calculations: 

1) Calculate surface area (m2). 

Surface area = 0.15*SQRT((((1.1+2)^2)/4)-1) = 0.178 m2 

2) Calculate tons/day, without temperature adjustment 

The metal fraction (0.20) would have no tank permeation emissions. 

(9.7 g/m2/day)*(0.178 m2)*(65,329)*(lb/453.6g)*(ton/2000 lb)*(1-0.2)*(1) = 0.10 tons/day 

3) Calculate temperature adjustment (50% lower with each 10°C reduction from 85°F) 

The temperature adjustment is applied from the average temperature for the scenario (75°F) 

Tank TCF °F = 3.788519E-2*exp(3.850818E-2*75°F) = 0.68 

4) Apply temperature adjustment 

(0.10 tons/day)*(0.68) = 0.068 tons/day 

5) Calculate tons/year
 

2005 is not a leap year, so it has 365 days.
 

Total: 0.068 tons/day * 365 days/year = 25 tons/year
 

Hose Permeation 

Fuel hose includes all fuel and vapor lines. Fuel hose permeation is estimated with the 

following general equation: 

Hose permeation (g/day) = hose permeation emission factor (g/m2

/day)*fuel hose surface area 

(m2)*TCF*(1-metal fraction)*DF 

15
 
 

where:
 

Fuel hose surface area (m2) = π * hose length (m) * inside hose diameter (m)
	

TCF = temperature correction factor
 

DF = deterioration factor
 

The TCF is calculated using the average temperature for the scenario. Thus, the inputs 

needed to estimate hose permeation emissions are the hose permeation emission factor, the hose 

length, the hose diameter, the average ambient temperature, the hose metal fraction, and the 

deterioration factor. 

Metal fuel lines are assumed to have zero permeation, so the metal fraction is not 

included in the calculation of emissions. Metal fuel lines are used in large SI equipment. 

The model has the capability of including deterioration, but no deterioration is assumed 

for hose permeation (i.e., all DFs equal to 1.0). DFs for all equipment except recreational marine 

vessels are contained in the evhose.det file. DFs for rec marine fill neck, supply/return and vent 

line hose types (also equal to 1.0) are contained in the evneck.det, evsupret.det, and evvent.det 

files, respectively. 

As mentioned in the discussion of fuel tank permeation, permeation is very sensitive to 

temperature. Generally, permeation roughly doubles with every 10°C increase in temperature. 

The temperature adjustment is applied from the average temperature for the scenario. Since the 

emission factors are based on a temperature of 73°F, the temperature adjustment reduces 

emissions by 50% with each 10°C reduction from 73°F. The temperature adjustment is 

calculated using the following equation: 

Hose TCF = 6.013899E-2*exp(3.850818E-2*Tavg) 

where Tavg = average temperature, °F 

The equation is a curve fit to the equation: TCF = 0.5*exp((23°C - X°C)/10). The temperature 

adjustment is hard coded in the model. 

Fuel hose dimensions were estimated for every piece of equipment. For 

NONROAD2008a, hose lengths for outboard boats with installed fuel systems were updated 

based on data supplied by a boat builder. The hose lengths and diameters by SCC and hp 

category are contained in the spillage.emf input file and provided in Appendix A, Table A4. 

The emission factors are provided in Appendix A, Table A7. The metal fraction inputs 

are provided in Appendix A, Table A4. 

The sections below discuss the hose permeation emission factors and hose characteristics 

used for each of the following nonroad categories: small SI, large SI, recreational marine, and 

recreational equipment. 

16
 
Small SI Hose Permeation 

Because permeation is a function of surface area and because hose lengths and inner 

diameters are defining parameters, hose permeation rates are based on g/m2/day. The hose 

permeation emission factors in NONROAD2008a incorporate a more complete set of data than 

those in NONROAD2005. In addition, distinctions are now made between permeation rates for 

liquid fuel versus fuel vapor exposure and between permeation rates for gasoline versus ethanolblend fuels. Based on data presented in the 2008 rulemaking documentation [7,9], we estimate 

non-handheld fuel hose permeation rates of 122 g/m2/day on gasoline and 222 g/m2/day on E10. 

For handheld equipment, hose permeation rates of 140 g/m2

/day on gasoline and 255 g/m2/day on 

E10 were estimated. A summary of the baseline small SI hose permeation emission factors in the 

model is provided in Table 6 below. 

Table 6. Small SI Hose Permeation Baseline Emission Factors at 23°C (g/m2

/day) 

Hose Type Gasoline (E0) E10 E10/E0 

Handheld equipment fuel hose 140 255 1.82 

Non-handheld equipment fuel hose 122 222 1.82 

Small SI equipment are subject to a 15 g/m2/day hose permeation standard. The phase-in 

schedule is dependent on the engine subcategory. The fuel hose test procedures are based on 

Fuel CE10 (Fuel C with 10 percent ethanol) as a test fuel. Based on the same data referenced 

above, we would expect in-use emissions on gasoline-based E10 to be about half of the measured 

level on Fuel CE10. In addition, we believe that hose designed to meet the final 15 g/m2

/day 

standard on E10 will permeate at least 50 percent less when gasoline is used. Therefore, we 

model permeation from hoses designed to meet 15 g/m2/day on Fuel CE10 to be 3.75 g/m2/day 

on gasoline at 23°C. No emission reductions are modeled for hose on handheld equipment used 

in cold weather applications (i.e., chainsaws). A summary of the control emission factors is 

given in Table 7.

Handheld chainsaw 140 255 1.82 

Handheld other 3.75 7.5 2.00 

Non-handheld equipment fuel hose 3.75 7.5 2.00 

Hose lengths are based on industry data. We use an inner diameter of 1/8 inch for hose 

on handheld equipment and 1⁄4 inch for non-handheld equipment. 

There are no metal hoses for small SI equipment, so the metal fraction is zero. 

17
 
 

Large SI Hose Permeation 

Most of the fuel lines for gasoline-fueled large SI equipment consist of metal lines 

connected by plastic sections for corners and bends. Engines meeting the large SI evaporative 

standards starting in the 2007 model year are expected to have near zero fuel line emissions, 

given the stringency of the standards. For modeling purposes, all large SI equipment are 

assumed to have metal fuel lines, so there are no hose permeation emissions from large SI 

gasoline equipment in NONROAD2008a. 

Recreational Marine Hose Permeation 

For the recreational marine category, hose permeation is the sum of emissions from three 

hose types: supply/return, fill neck, and vent line. Therefore, emission factors, hose lengths, and 

hose diameters are required for each hose type. There are separate emission factor input files for 

each hose type. 

The majority of marine fuel hoses are constructed primarily of nitrile rubber with a 

chloroprene cover for abrasion and flame resistance. Fuel hose for portable marine fuel tanks 

(used in outboard engines ≤25 hp) is not subject to any established recommended practice. For 

this reason, we consider fuel hose used on portable marine fuel tanks to be equivalent to the hose 

used in small SI applications. The supply hose for each portable marine fuel tank is modeled to 

include a primer bulb with the same permeation rate as the hose. 

For SD/I vessels, Coast Guard requirements in 33 CFR 183 (which reference SAE J1527) 

are that fuel hose for boats with gasoline engines meet the Class 1, Type A requirements which 

specify a maximum permeation rate of 100 g/m2

/day at 23°C. [10] Accordingly, these vessels 

have fuel hose with lower permeation. Rather than using the recommended permeation rate 

limits for this hose, which was done for the previous version of the model, we now base the 

baseline permeation emission factors on data using gasoline with ethanol, which is more 

representative of in-use fuels. [7] 

For other vessels with installed fuel tanks (i.e., PWC and outboard engines >25 hp), the 

baseline permeation emission factors are based on test data on marine hose not certified to Coast 

Guard Class I requirements. 

Fuel fill neck hoses are subject to a less stringent permeation standard (300 g/m2/day at 

23°C) under the Coast Guard specifications because they are not normally continuously in 

contact with fuel (Class 2). However, fill neck hose is not usually exposed to liquid fuel. 

Therefore, we used vapor line data to estimate both fill neck and vent line permeation rates. 

A summary of the recreational marine hose permeation baseline emission rates is 

provided in Table 8 and Table 9 below.

15 g/m2

*The gasoline EFs are contained in the supret.emf input file. The E10/E0 adjustment factors are hard coded in the 

model. 

Hose lengths and diameters by hose type are contained in the spillage input file. Our 

estimates of hose lengths are based on discussions with and comments from boat builders. In 

addition, the vent line lengths in NONROAD2005 were divided by two to account for a vapor 

gradient throughout the fuel line caused by diurnal breathing and diffusion. This factor has been 

removed in lieu of the new emission factors for vent lines based on vapor exposure. 

Fuel lines connected to a portable fuel tank are also generally fitted with a primer bulb, 

also typically constructed from nitrile rubber. To account for primer bulb emissions, the primer 

bulb hose surface area (0.012177m2 = π*0.1525m (length) * 0.0254 m (inside diameter)) was 

added to the supply/return hose surface area for portable equipment. This was done in the model 

by adjusting the supply/return length for portable equipment from 1.83m to 2.44m. 

Recreational Equipment Hose Permeation 

We consider fuel hose on recreational equipment to be constructed similar to SAI J30 R7 

hose, which has a permeation requirement of 550 g/m2

/day at 23°C. Considering that fuel hose is 

likely constructed to be below this requirement, a baseline emission factor of 450 g/m2

/day is 

used for all recreational equipment. A standard of 15 g/m2

/day is applied, beginning in the 2008 

model year. In NONROAD, a control emission factor of 7.5 g/m2/day is used for the 2008 and 

later model years. This is based on a 50 percent compliance margin to account for E10 fuel 

effects. 

Recreational equipment are assumed to have no metal hoses (i.e., metal fraction = 0.0).

Total: 0.76 tons/day * 365 days/year = 278 tons/year
 

Modeling of Ethanol Blend Effects on Fuel Tank and Hose Permeation Emissions 

Due to the increasing use of gasoline-ethanol blends, and the effects of such blends on 

permeation emissions, NONROAD2008a has been modified to be able to estimate these effects 

for small gasoline-fueled equipment and recreational boats. This section describes the 

methodology and presents an example calculation of tank permeation emissions when an ethanol 

blend fuel is used. 

Graphical User Interface (GUI)/Option File Changes 

Two new input fields have been added to the option file and GUI to allow users to specify 

ethanol blend market share and volume percent ethanol in the blend. Note that these new inputs 

are used to model the effects of ethanol blends on permeation emissions only. Other evaporative 

21
 
sources are not affected in the model by the use of ethanol blends. In addition, the model does 

not have the ability to model the effects of other oxygenate blends on permeation emissions. 

The effect of oxygenate blends (ethanol or otherwise) on exhaust emissions is modeled by 

specifying the oxygen weight percent input in the option file/GUI. If this input is not consistent 

with the new ethanol blend fields, the GUI/output file will provide a warning. The GUI prompt 

will also provide a suggested oxygen weight percent input that is consistent with the ethanol 

blend inputs specified. This prompt/warning can be ignored, however, and the model will still 

run. This may be necessary in some cases. For example, if an MTBE blend is modeled, the 

oxygen weight percent input would reflect this, but the volume percent ethanol and market share 

inputs would be set to zero, since the model does not have the ability to model the effects of 

MTBE blends on permeation emissions. 

Ethanol Blend Default Values 

In the absence of local information regarding ethanol blend market shares and volume 

percents, Appendix F contains suggested nationwide average fuel properties. [11] 

Modeling the Nonlinear Nature of the Permeation Effect 

Based on the limited available test data it appears that the effect of alcohol-gasoline 

blends on permeation is nonlinear, tending to increase permeation at lower alcohol 

concentrations up to about 20% ethanol, but then decreasing permeation at higher alcohol 

concentrations. [12] 

Starting with the gasoline (E0) and 10% ethanol (E10) emission factors described above, 

a simple exponential curve was selected to connect the zero and 10% points continuing up to the 

20% ethanol level. Then to get a nonlinear decreasing curve above 20% a simple decreasing 

exponential curve was used. Since effects above 85% are especially uncertain, and no such fuels 

are foreseen for use in nonroad equipment, the effect above 85% was set equal to the E85 effect. 

[9] The equations used are shown below. 

Hose and Tank Permeation for 0 - 20% ethanol volume percent: 

Permeation EF = GasEF + GasEF * (E10fac - 1) * [ (EthVfrac / 0.10) ^ 0.4 ] 

Hose and Tank Permeation for ethanol volume percent greater than 20%: 

Permeation EF = GasEF * { 1 + (E10fac - 1) * [ (20 / 10) ^ 0.4 ] } 

* { 1 - [ (MIN(EthVfrac, 0.85) - 0.20 ) / 0.80 ] ^ (1 / 0.4 ) } 

where: 

Permeation EF = Permeation emission factor for modeled fuel (grams per meter2 

per day) 

22
 
GasEF = Gasoline hose permeation emission factor from input EF data files 

(grams per meter2 per day) 

E10fac = permeation emission adjustment factor for E10 relative to gasoline, from 

input EF data file (spillage.emf), (unitless) 

EthVfrac = Volume fraction ethanol in the fuel being modeled. E10 = 0.10 

0.4 = exponent chosen to yield a reasonable shape of curve. 

The E10 adjustment factors are contained in the spillage file and provided in Appendix A, Table 

A5. 

Note that all ethanol blends currently modeled with NONROAD or NMIM are less than or 

equal to E10, so no parts of this curve above E10 are used yet. If/when nonroad equipment starts 

being designed for operation on blends greater than E10, there may be other hose or tank material 

changes that require revisiting this analysis. 

Market Share Effect 

The effect of market share is modeled based on the proportion of ethanol blend use in the 

market being modeled. In most areas the ethanol blend market share is either zero or 100%, but 

in areas where it is between those two market shares, or when doing a nationwide model run, the 

effect is calculated as a simple proportion. 

Sample Calculation of Permeation Emissions with Ethanol Blends 

A sample calculation of tank permeation emissions with a 9.3 percent ethanol blend is provided 

for small SI equipment. This is the same equipment type used previously to illustrate the 

calculation of tank permeation emissions with gasoline. 

User Inputs: SCC: 2265006015 (4-stroke air compressors) 

MaxHP: 6 

Tavg: 75°F 

Calendar year: 2005 

Ethanol blend market percent: 90.0 

Ethanol blend volume percent: 9.3 

Model Inputs: Gasoline EF: 9.7 g/m2

/day at 85°F (evtank.emf) 

E10 permeation adjustment factor: 1.100 (spillage.emf) 

Tank size: 1.1 gal (spillage.emf) 

Tank metal fraction: 0.2 (spillage.emf) 

DF: 1 (evtank.det) 

23
 
Engine population in 2005: 65,329 (model output) 

Calculations: 

1)	 Calculate tank permeation EF for 9.3 ethanol volume percent.
 

Permeation EF = GasEF + GasEF * (E10fac – 1) * [(EthVfrac/0.10)^0.4]
 

E9.3 EF = 9.7 + 9.7 * (1.1 – 1) * [(0.093/0.10)^0.4] = 10.64 g/m2

/day
 

2)	 Calculate composite tank permeation EF, accounting for ethanol market share. 

(10.64 * 0.900) + [9.7 * (1-0.900)] = 10.55 g/m2

/day 

3)	 Calculate surface area (m2

).
 

Surface area = 0.15*SQRT((((1.1+2)^2)/4)-1) = 0.178 m2
 

4) Calculate tons/day, without temperature adjustment
 

The metal fraction (0.20) would have no tank permeation emissions.
 

(10.55 g/m2/day)*(0.178 m2

)*(65,329)*(lb/453.6g)*(ton/2000 lb)*(1-0.2)*(1) = 0.108 tons/day 

5) Calculate temperature adjustment (50% lower with each 10°C reduction from 85°F) 

The temperature adjustment is applied from the average temperature for the scenario (75°F) 

Tank TCF °F = 3.788519E-2*exp(3.850818E-2*75°F) = 0.68 

6)	 Apply temperature adjustment 

(0.108 tons/day)*(0.68) = 0.074 tons/day 

7) Calculate tons/year
 

2005 is not a leap year, so it has 365 days.
 

Total: 0.074 tons/day * 365 days/year = 27 tons/year
 

Running Loss Emissions 

The running loss inventory is estimated by multiplying the running loss emission rates in 

g/hr by the total activity in hours for each equipment type. Running loss emissions are not 

dependent on ambient temperature, so no temperature adjustment is necessary. 

The model has the capability of including running loss deterioration, but no deterioration 

is assumed for running loss emissions (i.e., all DFs equal to 1.0). The DFs are contained in the 

evrunls.det file. 

Small SI Running Loss 

Running loss baseline emission rates are available for several small SI applications, 

which are provided in Table 11 below. Although the ATVs and forklifts are not considered to be 

small SI equipment, these data can be used as surrogates for equipment that were not tested. The 

24
 
source and derivation of these emission factors are provided in Appendix G. These emission 

factors are then mapped/assigned to all the SCCs in NONROAD. The mapping of emission 

factors to SCCs is also described in Appendix G. 

Table 11. Small SI Running Loss Baseline Emission Factors

ATV 11.30 

Forklift 4.61 

Riding Mower 2.86 

Trimmer/Edger 0.58 

Lawnmower 3.34 

Generator/Pressure Washer 14.23 

Running loss control requirements for nonhandheld engines take effect in the 2012 model 

year for Class I engines and the 2011 model year for Class II engines. For Class I engines, we 

believe that the final running loss control requirement will be met by routing vapor from the fuel 

take to the engine air intake system. Therefore, all vapor generated in the fuel tank should be 

consumed by the engine, thereby eliminating running loss emissions. However, there may be 

some inefficiencies in the system such as vapor escaping out the intake at idle. Therefore, we 

model the running loss emission reduction as only 90 percent. For Class II equipment, we 

believe that some equipment will inherently meet the final standard because they will have low 

enough temperature fluctuation in the fuel tanks during operation to certify by design. Based on 

fuel tank temperatures during operation, we estimate an 80 percent reduction in running loss for 

Class II equipment. 

Large SI Running Loss 

A baseline running loss emission factor of 2.41 g/hour is used for all large SI equipment. 

This is based on an average derived from data collected on eight pieces of equipment. The data 

and derivation of the emission factor are described in Appendix G. 

Regulations resulting in 90% control start in the 2007 model year; the control emission 

factor used in NONROAD is therefore 0.241 g/hr, beginning in 2007. 

Recreational Marine Running Loss 

We do not have running loss data for recreational marine engines. Presumably, boats 

with outboard engines would not have significant running loss emissions from the fuel tank. 

Also, for larger fuel tanks, we assume that the fuel tank is mounted away from the engine and is 

not significantly affected by engine heating. For the other categories (PWC and smaller 

inboard/sterndrive engines), an emission factor of 2.86 g/hour is used, based on data collected for 

riding mowers. The derivation of the emission factors is described in Appendix G and the 

25
 
resulting emission factors are provided in Table 12. There are no recreational marine running 

loss controls, so these emission factors are applied for all model years.

Recreational Equipment Running Loss 

An ATV emission factor of 11.3 g/hour is used for all recreational equipment, described 

in Appendix G. Since the activities for off-road motorcycles and ATVs are in units of 

miles/year, it is necessary to convert the emission factor to consistent units of g/mile for this 

equipment. This is done by dividing the g/hour emission factor by the average speed in 

miles/hour. The average speed for ATVs is 9.6 miles/hour, which is a weighted average for 

utility and sport ATVs. [13] The average speed for off-road motorcycles is 20 miles/hour, which 

is consistent with the average speed used by California in their modeling. [14] The resulting 

running loss emission factors used in the model are 1.18 g/mile for ATVs and 0.57 g/mile for 

off-road motorcycles. 

There are no recreational equipment running loss controls. 

Running Loss Sample Calculation 

A sample calculation is provided for small SI equipment. 

User Inputs: SCC: 2265006015 (4-stroke air compressors) 

MaxHP: 6 

Calendar year: 2005 

Model Inputs: EF: 14.23 g/hour (evrunls.emf) 

Activity: 484 hours/year (activity.dat) 

DF: 1 (evrunls.det) 

Engine population in 2005: 65,329 (model output) 

Calculations: 

1) Calculate tons/year 

(14.23 g/hour)*(484 hours/year)*(65,329)*(lb/453.6g)*(ton/2000 lb) = 496 tons/year 

26
 
Hot Soak Emissions 

The hot soak inventory is estimated by multiplying the hot soak emission rates in g/start 

by starts/hour and hours/year activity information. In this case, starts are equivalent to the engine 

being turned off, since the latter is when a hot soak occurs. Hot soak emissions are not 

dependent on temperature, so no temperature adjustment is necessary. 

The upper limit for number of starts is 260 starts/year (based on 5 days/week and 52 

weeks/year). To check that this limit is not exceeded, for each equipment type, we calculated 

starts/year by multiplying starts/hour and hours/year. This was done outside the model. If the 

resulting starts/year was greater than 260, the starts/year was reset to 260 and the starts/hour 

estimate was adjusted downward accordingly. The starts/hour estimates in the spillage.emf file 

contain these adjustments. 

The emission factors are in the evhotsk.emf input file and also provided in Appendix A, 

Table A10. The starts/hour estimates by equipment type are provided in the spillage.emf file and 

provided in Appendix A, Table A3. Both the emission factor and start/hour estimates are 

described in more detail in Appendix H. 

As with the other emission types, the model has the capability of including deterioration, 

but no deterioration assumed for hot soak emissions (i.e.,all DFs equal to 1.0). The DFs are in 

the evhotsk.det file. 

Small SI Hot Soak 

Hot soak emission rates are available for several small SI applications, which are 

provided in Table 13 below. There are no small SI hot soak controls, so the baseline emission 

factors are applied to all model years. 

Table 13. Hot Soak Emission Factors Used for Small SI Equipment

27
 
Large SI Hot Soak 

A baseline running loss emission factor of 4.34 g/start is used for all large SI equipment. 

This is based on an average derived from data collected on eight pieces of equipment. 

Regulations resulting in 90% control start in the 2004 model year; the control emission 

factor used in NONROAD is therefore 0.434 g/hr, beginning in 2004. 

Recreational Marine Hot Soak 

There are no hot soak emission data for recreational marine engines. An emission factor 

of 3.0 g/start is used for all recreational marine engines, except those using portable tanks. This 

emission factor is based on ARB tests with ATVs. There are no hot soak emissions for portable 

equipment (i.e., outboards <=25hp). 

There are no recreational marine hot soak controls in the NONROAD model. 

Recreational Equipment Hot Soak 

An ATV emission factor of 3.0 g/start is used for all recreational equipment. Since the 

activities for off-road motorcycles and ATVs are in units of miles/year, the hot soak inventory for 

this equipment is estimated by multiplying the hot soak emission rates in g/start by starts/mile 

and miles/year activity information. As described in Appendix H, there are 1.00 starts/hour 

assumed for recreational equipment. To convert to units of starts/mile, the starts/hour are divided 

by the average speed in miles/hour. The average speed for ATVs is 9.6 miles/hour, which is a 

weighted average for utility and sport ATVs. [13] The average speed for off-road motorcycles is 

20 miles/hour. [14] The resulting starts/mile values used in the model are 0.1042 starts/mile for 

ATVs and 0.0500 starts/mile for off-road motorcycles. The starts/mile values are contained in 

the spillage.emf file. 

There are no recreational equipment hot soak controls.

Diurnal Test Data
 

Comparison of Test Data to Theoretical Results Using the Wade Equations 

We tested two marine fuel tanks in their baseline configurations for diurnal emissions. 

These fuel tanks included a portable plastic fuel tank and two aluminum fuel tanks. The 17 

gallon aluminum tank was constructed for this testing, but is representative of a typical marine 

fuel tank; the 30 gallon aluminum tank was removed from an 18 foot runabout. The fuel tanks 

were tested with the venting through a length of 5/8 inch hose to ensure that the emissions 

measured were a direct result of the fuel temperature heating and not diffusion. The advantage of 

using the aluminum fuel tanks for this testing was to exclude permeation emissions from the 

measured results. All testing was performed with fuel tanks filled to 40% of capacity with 9 

RVP test fuel. 

The diurnal test results are presented in units of grams per gallon capacity of the fuel tank 

per day. These units are used because gallons capacity is a defining characteristic of the fuel 

tank. Diurnal vapor formation itself is actually a function of the vapor space above the fuel in the 

fuel tank rather than the total capacity. 

Table C1 presents the test results compared to theoretical results. The theoretical results 

are based on the Wade model which is a set of theoretical calculations for determining diurnal 

emissions based on fill level, fuel RVP, and temperature profile. These calculations are 

presented in Appendix B. Although the Wade model over-predicts the vapor generation, it does 

show a similar trend with respect to temperature. To account for this over prediction, we use a 

correction factor of 0.78. This correction factor is based on empirical data 1

, has historically been 

used in our automotive emission models, and appears to be consistent with the data presented in 

Table C1. 

We also contracted with an outside lab 2,3 for the testing of thirteen small SI fuel tanks 

over various test temperature profiles. This testing was performed with the tanks filled to 50% 

capacity with certification gasoline. These data are presented in Table C2. In cases where the 

fuel temperature profiles were within the input range of the Wade model for diurnal emissions, 

theoretical emissions were also calculated using the Wade model and applying the same 

correction factor discussed above for SI marine fuel tanks. As shown in Table C2, the measured 

values are fairly consistent with the theoretical values.

Ambient vs Fuel Diurnal Temperature Swings 

In boats with installed fuel tanks, the fuel tank is generally hidden beneath the deck. As a 

result, there is a certain amount of “inherent” insulation caused by the boat itself. This effect is 

increased for a boat that is stored in the water. The water acts as a cooling medium for the fuel 

tank, especially if it is installed in the bottom of the boat. In addition, the thermal inertia of the 

fuel in the tank can act to dampen temperature variation imposed from the diurnal heating of the 

ambient air. To investigate this effect, we tested several boats by recording the ambient air 

temperature and fuel temperatures over a series of days. Two boats were tested on trailers 

outside in the summer, two boats were tested on trailers in a SHED, and two boats were tested in 

the water on summer days. Table C3 presents the average results of this testing

* Average ratio of change in fuel temperature to change in ambient air temperature over test days. 

In their comments on the proposed rule, the National Marine Manufacturers Association 

presented temperature data on an 18 foot runabout, with a 32 gallon tank, tested in a SHED with 

an ambient temperature of 72-96°F.4 The average fuel to ambient temperature ratio was 54% for 

this testing. This ratio is in the range of EPA test results for boats tested on a trailer. Brunswick 

also included temperature data in their comments.5 The average days test on a boat on the water 

was 19%, which is consistent with our water tests. Brunswick’s average for boats tested while 

stored out of the water was 27% which is considerably lower than the EPA and NMMA testing. 

Combining all of the EPA and industry data, the average fuel to ambient temperature ratio (based 

on test days) is about 20% for boats in the water and 50% for boats stored out of the water.

During diurnal testing of lawnmowers, ARB found that the fuel and tank skin temperature 

follow the ambient temperature closely.6 This same phenomenon would be expected for other 

small SI equipment as well (and portable fuel tanks) because of the small fuel volumes and 

because these tanks are generally exposed to ambient air. 

Diffusion Effect 

In testing diurnal emissions from fuel tanks with open vents, the configuration of the vent 

can have a significant effect on the measured emissions due to the diffusion of vapor out of any 

opening in the fuel tank. Depending on the size and configuration of the vent, diffusion can 

actually occur when the fuel temperature is cooling. To quantify this diffusion component for a 

typical fuel tank, we ran four 72-96°F diurnal tests on a 17 gallon aluminum tank using various 

configurations for venting. The first configuration was with the fuel cap cracked open and the 

vent sealed, the second configuration was with a 68 cm length of vent hose, and the third 

configuration was with a 1000 micron limiting flow orifice in the vent opening. This 1000 

micron orifice was large enough to allow venting without any measurable pressure increase in the 

fuel tank during the diurnal test. The fourth configuration was a combination of the limited flow 

orifice and the vent hose. Table C4 presents the results of this testing.

In the test with the cracked fuel cap, an increase in HC concentration in the SHED was 

observed throughout the test, even when the fuel temperature was cooling. For the other three 

tests, the HC concentration leveled off when the temperature began to cool. This suggests that 

the difference in measured emissions of 0.6 - 0.7 g/gal/day was due to diffusion losses. 

Based on these data, we see about 40-50% higher emissions over a diurnal test for a tank 

with a small vent directly to the atmosphere than for a tank that is vented through a hose. In our 

modeling, we use a correction factor of 1.46, which is equal to the open vent rate (2.05 

g/gallon/day) divided by the average of the three limited vent rates (1.40 

g/gallon/day=avg[1.39,1.47,1.34]).

To further investigate this diffusion effect, we tested the 17 gallon aluminum tank with 

several venting configuration, at two constant temperature settings. Under these conditions, all 

of the measured evaporative emissions would be expected to be due to diffusion. As seen in 

Table C5, diffusion can be very high with too large of a vent opening unless a vent hose is used. 

The two lengths of vent hose tested did not show a significant difference in diffusion emissions. 

We believe that the vent hose limits diffusion by creating a gradual gradient in fuel vapor 

concentration. 

Table C5. Constant Temperature Test Results with Varied Venting Configurations 

Vent Configuration 22°C (72°F)

137 cm of 5/8" fuel hose 0.07 0.24 

1000 micron orifice 0.28 0.41 

The above data suggest that, at least for open vent fuel systems, the size and configuration 

of the venting system can have a significant effect on evaporative emissions. In marine 

applications, there is typically a vent hose attached to the fuel tank. Diffusion emissions appear 

to be minimal if the fuel tank is vented through a length of hose. This is probably because the 

long residence times in the hose cause more opportunities for molecular collisions which direct 

the HC molecules back towards the fuel tank. 

One study looked at the evaporation of liquids from a tube filled to various fill heights.7 

As the fill height decreased (effectively increasing the length of the tube above the liquid surface) 

the evaporation quickly decreased. These results are consistent with the observed effects of 

venting through a hose in our testing. Installed marine fuel tanks typically vent through a hose to 

the outside of the boat; therefore, diffusion losses are likely relatively small for these 

applications. 

For small SI applications and portable marine fuel tanks, the tanks are typically vented 

through an opening in the fuel cap. Therefore, unless the cap is sealed, we would expect 

diffusion emissions to occur. The above data suggest that diffusion can account for a significant 

portion of the evaporative HC emissions measured from a metal tank with a small vent in the cap

over a 72-96°F diurnal test. The contribution of diffusion to measured diurnal emissions would 

increase, on a percentage basis, as the diurnal temperature swing approached zero. 

Sealed System with Pressure Relief 

For the pressure relief valve testing, we looked at several pressures ranging from 0.5 to 

2.25 psi. The 2.25 psi valve was an off-the-shelf automotive fuel cap with a nominal 2 psi 

pressure relief valve and 0.5 psi vacuum relief valve. For the other pressure settings, we used 

another automotive cap modified to allow adjustments to the spring tension in the pressure relief 

valve. We performed these tests on the 17 gallon aluminum fuel tank to remove the variable of 

permeation. Emissions were vented through a hose to prevent diffusion losses from affecting the 

measurements. We operated over two temperature profiles. The first set of tests were performed 

in a variable temperature SHED with a 72-96°F air temperature profile. This temperature profile 

was based on the existing automotive cycle which is intended to represent a typical summer day 

on which a high ozone event may occur. The second set of tests were performed using a heating 

blanket to create a 78-90°F fuel temperature profile. This testing was intended to represent a fuel 

tank in a boat, where the tank may be inherently insulated, during the same ambient temperature 

profile. This inherent insulation creates a time lag on the heating and cooling of the fuel and 

reduces the amplitude of the temperature profile by half. 

As shown in Figure C1, there was a fairly linear relationship between the pressure setting 

of the valve and the emissions measured over the proposed test procedure. In addition, the slope 

of the lines are similar for both test temperature scenarios. This suggests that over a smaller 

temperature profile, a greater percent reduction in HC can be achieved at a given pressure setting. 

This is reasonable because, in each case, a constant amount of vapor is captured. In other words, 

regardless of the temperature profile, the same amount of vapor must be generated to create a 

given pressure. For instance, with a 1 psi valve, about 0.4 grams/gallon of HC are captured over 

each temperature profile. However, this represents a 50% reduction over a 78-90°F temperature 

profile while only about a 25% reduction over the 72-96°F temperature profile. 

Personal watercraft have sealed systems with pressure relief valves that range from 0.5 to 

4.0 psi. These tanks are modeled as having a 1 psi pressure relief valve. The effect of a 1 psi 

valve on diurnal emissions is estimated to be a 70% reduction, which is based on a comparison 

of annual diurnal emissions with and without the relief valves, using regional daily RVP values.

Relationship Between Tank Size and Surface Area
 

Both EPA and ARB measured the fuel tank surface areas of a number of different fuel 

tanks of varying applications and volumes. These data are shown in Table D1. EPA developed a 

hyperbolic expression to fit through the volume and surface area data, which is shown in Figure 

1. The expression is shown below: 

surface area (m2) = 0.15*SQRT((((gal+2)^2)/4)-1) 

With regard to data not falling exactly on this curve, there is point at about 4 gallons, 

where the surface area is around 0.7 m2

, and the curve predicts about 0.5 m2. For this case, we 

would be underpredicting emissions by about 29%. However, there are several points around 15 

gallons, where the curve predicts tank surface area to be about 1 m2, but the data indicates about 

0.75 m

2

. Here, we would be overpredicting emissions by about 30%. Note that at very small tank 

sizes, which represent lawnmowers, the curve appears to do a good job of predicting surface area.

Derivation of Tank Permeation Emission Factors (precontrolled on gasoline)
 

Small SI and Recreational Equipment 

ARB tested a number of equipment fuel tanks for permeation emission rates. The ARB 

data is compiled in several data reports on their web site.8,9,10,11,12 In the testing, the equipment 

tanks were fueled to 100% with California Phase 2 fuel, and allowed to sit for a couple of 

months. ARB measured the tank volumes, and also the surface area of each of the tanks. ARB 

used the 18 - 41°C 24 hour diurnal test, but the tanks were sealed so that they did not emit any 

vapor emissions. The results are shown in Table E1 below. Where multiple tests were run on a 

given tank or tank type, the average results are presented. Although the temperature in the ARB 

testing is cycled from 18 - 41°C rather than held at a constant temperature, the results would 

likely be similar if the data were collected at the average temperature of 29°C.

Some handheld equipment, primarily chainsaws, use structurally-integrated fuel tanks 

where the tank is molded as part of the body of the equipment. In these applications, the frames 

(and tanks) are typically molded out of nylon for strength. We tested structurally-integrated fuel 

tanks from four handheld equipment manufacturers at 29°C on both gasoline and a 10 percent 

ethanol blend. In the cases where the permeation rates were high, it was observed that the fuel 

cap seals had large exposed surface areas on the O-rings, which were not made of low 

permeation materials. Emissions could likely be reduced significantly from these tanks with 

improved seal designs. Table E3 presents the results of this testing. Note that permeation 

emissions are 20 to 70 percent higher on E10 than on gasoline for these fuel tanks.

Based on the above, it is reasonable to break the tanks into three categories, HDPE tanks 

below 0.25 gallons, HDPE tanks above 0.25 gallons, and nylon handheld fuel tanks. Because all 

recreational equipment have tank sizes above 0.25 gallon, the emission factor of 9.7 g/m2

/day is 

used for all uncontrolled recreational equipment tanks. 

Recreational Marine Equipment 

To determine the baseline permeation emissions from marine fuel tanks, we have 

collected permeation data on several plastic fuel tanks. Because gasoline does not permeate 

through aluminum, we did not perform permeation testing on aluminum fuel tanks. 

We tested ten plastic fuel tanks that were either intended for marine use or are of similar 

construction. This permeation testing was performed at 29°C with gasoline. Prior to testing, the 

fuel tanks were stored with gasoline in them for about 20 weeks to ensure stable permeation 

rates. Table E4 presents the measured permeation rates for these fuel tanks in grams per gallon 

of fuel tank capacity. Where the internal surface area was either easily determined or supplied by 

the manufacturer, we also calculated the permeation rate in terms of grams per square meter of 

inside surface area. The 31 gallon tank showed much lower permeation than the other fuel tanks. 

This was likely due to the thickness of the walls in this tank. Even after stabilization, 

permeation is a function of material thickness. According to Fick’s Law, if the wall thickness of 

a fuel tank were double, the permeation rate would be halved.13 Smaller plastic marine fuel tanks 

are currently constructed out of high-density polyethylene (HDPE) while larger ones are 

generally constructed out of cross-link polyethylene (XLPE). Marine fuel tanks may also be

The Coast Guard tested three rotationally-molded, cross-link polyethylene marine fuel 

tanks at 40°C (104°F) for 30 days.14 The results are presented in Table E5. Because permeation 

emissions are a function of surface area and wall thickness, there was some variation in the 

permeation rates from the three tanks on a g/gal/day basis. These results are not directly 

comparable to the EPA testing because of the difference in test temperature. However, we can 

adjust the permeation rates for temperature using Arrhenius’ relationship15 combined with 

empirical data collected on permeation rates for materials used in fuel tank constructions 

(described below). These adjusted permeation rates are shown in Table E5 and are consistent 

with the EPA test data.

In addition to the data presented above in Table E1, the California Air Resources Board 

(ARB) also investigated permeation rates from portable fuel containers using the same test 

methodology.16 This data is presented in Table E6. Although this testing was not on portable 

marine fuel tanks, the fuel tanks tested are of similar construction. Because most marine fuel 

tanks are 5 gallons and above only the data in for tanks 5 gallons and above are included. Table 

E6 also includes data on small SI fuel tanks 5 gallons and larger from the reports cited above for 

small SI fuel tanks.

To develop emission factors for marine fuel tanks, we use the data in tables E4 through 

E6. Because permeation is a function of surface area, we base the emission factors on units of 

g/m2/day. In cases where the data was reported only in terms of g/gal/day, we convert the data 

using the relationship established in Appendix D. Table E7 presents these emission factors. We 

use the HDPE emission factor for portable marine fuel tanks and for personal watercraft. For

Derivation of Running Loss Emission Factors and SCC Assignments
 

Sources of Data 

The California Air Resources Board performed running loss tests on several pieces of 

small SI equipment. 17 This equipment included four lawnmowers (2 new and 2 old), one string 

trimmer, two generators, two ATVs, and two forklifts. To measure running loss emissions, the 

equipment were operated on California certification fuel in a SHED and the exhaust was routed 

outside the SHED. Running loss emissions were determined by measuring the HC concentration 

in the SHED. Therefore, the measurements included all evaporative emissions during operation 

including those from fuel heating, permeation, carburetor losses, and, for the two older 

lawnmowers, liquid fuel leaks. Although permeation is included, its contribution to total running 

loss emissions should be minimal. Although the ATVs and forklifts are not considered to be 

small offroad engines, these data can be used as surrogates for equipment that were not tested. 

Table G1 presents these data.

EPA also collected running loss data. To investigate running loss emissions, we 

instrumented seven riding lawnmowers, three walk-behind lawnmowers, two generators, and one 

pressure washer to measure the fuel temperature during typical operation. Of the riding mowers, 

two had fuel tanks in front near the engine, three had fuel tanks in rear away from engine (but 

near the hydraulic system), and two were “zero-turn” mowers that had pairs of side saddle 

engines that were relatively close to the rear mounted engine. All of the riding mowers had 

plastic fuel tanks. One of the walk-behind mowers had a metal tank directly mounted to the 

block while the others had plastic tanks near the top/side of the engine. Both generators had 

plastic tanks mounted above the engine while the pressure washer had a metal tank mounted 

above the engine. All of the equipment vented through the fuel caps. The pressure washer had a 

metal fuel tank mounted above the engine. The equipment was operated in the field until the fuel 

temperature stabilized. For lawnmowers, the fuel temperature stabilized within 20 to 30 minutes 

while the larger equipment took up to an hour. 

By measuring the increase in fuel temperature during operation, we were able to make a 

simple determination of the running loss emissions vented from the fuel tank. Other potential 

running loss emissions would be from the carburetor, due to permeation increases due to heating 

the fuel, or vibration-induced leaks in the fuel system. However, we believed that the majority of 

the running loss emissions would be due to breathing losses associated with heating the fuel. 

Table G2 presents the results of the temperature testing. 

We contracted with an independent testing laboratory to test fuel tanks from most of the 

above pieces of equipment over the measured fuel temperature profiles. 18 For three of the tests 

on larger fuel tanks, we found that the measured emissions were inconsistent with theoretical 

predictions. An investigation of the test data suggested that the test had been ended too soon to 

see the full effect of the heat build. Repeat tests were performed with a longer sample time. 19 

From these data we get the running loss emissions due to the breathing losses associated with the 

heating of the fuel tank. New tanks were purchased for this testing that had not been previously 

exposed to fuel so permeation emissions would not be included in the emission measurements. 

Table G2 also presents the test results for the above equipment.

Running Loss Emission Factors for Small SI Equipment

Generator/Pressure Washer ARB and EPA 14.23 

The ATV, forklift, and trimmer/edger emission factors are the averages of the ARB data 

for each application presented in Table G1. Similarly, the riding mower emission factor is the 

average of the EPA data for this application presented in Table G2. 

For lawnmowers (walk-behind mowers), the emission factor was derived from the ARB 

and EPA data presented in Tables G1 and G2. First, separate emission factors were estimated for 

metal and plastic tanks. The emission factor for lawnmowers with metal tanks is 8.12 g/hour, 

from the EPA data in Table G2. For lawnmowers with plastic tanks, there are both ARB and 

EPA data. Two of the walk-behind mowers tested by ARB (Mower19 and Mower23) were 

determined to be leakers in the original test report. It is not possible to determine the incidence 

of leakers with accuracy. These two mowers are also near the end of their useful life. To attempt 

to correct for these outliers without excluding them, they are averaged and given a minimum 

weighting of 5% rather than given equal weighting. The remaining data (Mower8 and Mower9 

G4
 
in Table G1 and the two lawnmowers with plastic tanks in Table G2) were averaged and 

weighted at 95%, and a composite emission factor of 2.14 g/hr was calculated for lawnmowers 

with plastic tanks. 

Second, the emission factors for metal and plastic tanks were combined to determine a 

composite lawnmower emission factor. The lawnmower with the metal tank represents a model 

with a high sales volume. Therefore, we weighted this data into the emission factor 

determination based on our understanding of the sales fraction of similar model types. As a 

result, the emission factor for lawnmowers with metal tanks (8.12 g/hour) was weighted at 20% 

and the emission factor for lawnmowers with plastic tanks (2.14 g/hr) was weighted at 80% to 

obtain the composite lawnmower emission factor of 3.34 g/hour. 

The data for pressure washers was weighted in with the generator sets to create a single 

emission factor, due to the similarity of the equipment configurations. For the generator/pressure 

washer category, the emission factor was derived from the ARB and EPA data presented in 

Tables G1 and G2. One of the generators tested by EPA is an extreme outlier, having an 

emission factor of 69.3 g/hour in Table G2. Because this effect was real and because of the 

limited data available, this data point was not excluded. Rather, it was given a low weighting 

(5%) similar to the approach taken for the leaking lawnmowers. The remaining data (Generator1 

and Generator2 in Table G1 and the other generator and pressure washer in Table G2) were 

averaged and weighted at 95%, and a composite emission factor of 14.23 g/hr was calculated for 

generator/pressure washers. 

Running Loss Emission Factors for Large SI Equipment 

A running loss emission factor of 2.41 g/hour is used for all large SI equipment. It is the 

average of all equipment included in the SCAQMD test program. The data are provided in Table 

G3. 

Running Loss Emission Factors for Recreational Marine Engines 

We do not have running loss data for recreational marine engines. Presumably, boats 

with outboard engines would not have significant running loss emissions from the fuel tank. To 

generate a rough estimate, we use the emission factor for riding mowers given in Table F4 (2.86 

g/hour) for personal watercraft and smaller SD/I vessels (tank sizes up to 20 gallons). SD/I 

vessels with tank sizes up to 20 gallons correspond to SD/I vessels <=100 hp. For larger fuel 

tanks, we assume that the fuel tank is mounted away from the engine and is not significantly 

affected by engine heating. A summary of the recreational marine running loss emissions rates 

used in the NONROAD model are given in Table G5.

Running Loss Emission Factors for Recreational Equipment 

The ATV emission factor of 11.3 g/hour given in Table G4 is used for all recreational 

equipment. Since the activities for off-road motorcycles and ATVs are in units of miles/year, it 

is necessary to convert the emission factor to consistent units of g/mile for these equipment. This 

is done by dividing the g/hour emission factor by the average speed in miles/hour. The average 

speed for ATVs is 9.6 miles/hour, which is a weighted average for utility and sport ATVs. The 

average speed for off-road motorcycles is 20 miles/hour. The resulting running loss emission 

factors used in the model are 1.18 g/mile for ATVs and 0.57 g/mile for off-road motorcycles. 

Assignment of Small SI Emission Factors to Equipment Types 

The small SI emission factors were then mapped to other applications based on similar 

characteristics of the equipment. Specialty vehicle carts and golf carts were assigned the ATV 

emission factor. In general, equipment less than or equal to 3 hp were assigned the 

trimmer/edger emission factor, with 3-6 hp equipment assigned the lawnmower emission factor, 

and 6-25 hp equipment assigned the forklift emission factor. For construction equipment, 

equipment less than or equal to 6 hp were generally assigned the lawnmower emission factor. 

The riding mower emission factor was used instead for certain lawn and garden equipment. The 

generator/pressure washer emission factor was used generally for 6-25 hp commercial equipment 

and for other equipment used in a similar fashion (i.e., signal boards/light plants and 

AC/refrigeration).

Derivation of Hot Soak Emission Factors, Starts/Year, and SCC Assignments
 

Sources of Emissions Data 

Test data on hot soak emissions for different equipment types is available from testing by 

the Air Resources Board. 21 Hot soak emissions were measured after operating each piece of 

equipment for 15 minutes after which the equipment was placed in a shed at a constant 

temperature of 95°F for three hours. 

ARB divided the various pieces of equipment into “new”, “used”, and “old”, where ARB 

felt there was enough data to do this (i.e., lawnmowers and generators), and used the new engine 

to represent emissions at zero hours, used engines to represent emissions at the useful life, and 

old engines to represent the emissions at the end of life. These emission levels were then used to 

develop deterioration rates. 

Rather than take this approach, we simply assumed that there is no deterioration and 

estimated average hot soak emissions rates from the ARB data. The ARB data and average 

emissions by equipment type are provided in Tables H1 and H2. 

Because of the lack of data at different fuel volatilities and temperatures, the hot soak 

emission factors are not corrected for either fuel volatility or ambient temperature. Also, since 

the hot soak emissions are based on a SHED test, they include permeation emissions. Without 

knowing the exact materials used in each of these equipment types, it is difficult to subtract the 

permeation emissions, so the hot soak emissions obtained with this test program may be 

overestimated. However, the permeation emissions during the 15 minute test period should be 

very small compared to the hot soak emissions. 

The South Coast Air Quality Management District (SCAQMD) also sponsored hot soak 

tests on several pieces of large SI equipment, using California Phase II fuel. This equipment 

included three forklifts, one sweeper, one scrubber, one tow tractor, one baggage belt loader, and 

one boom lift. 22 The data are provided in Table H3.

Hot Soak Emission Factors for Small SI Equipment 

The ARB data (averages by equipment type) were used for the small SI hot soak emission 

factors. A summary of these emission factors is given in Table H4. Each 3-hour event is 

considered one start, so the emission factors are expressed as g/start.

Hot Soak Emission Factors for Large SI Equipment 

A baseline hot soak emission factor of 4.34 g/start is used for all large SI equipment. It is 

the average of all equipment used in the SCAQMD program. The data are provided in Table H3. 

Hot Soak Emission Factors for Recreational Marine Engines 

We do not have hot soak data for recreational marine engines. The ATV emission factor 

of 3.00 g/start from Table H1 is used for all recreational marine engines. 

Hot Soak Emission Factors for Recreational Equipment 

The ATV emission factor of 3.00 g/start from Table H1 is used for all recreational 

equipment. 

Starts Per Hour Activity Estimates 

A summary of the starts per hour activity estimates is given in Table H5. Starts and soaks 

are used interchangeably. 

The residential lawnmower estimate of 2.0 soaks/hour is modified from an ARB data 

H4
 
logger study showing 2.9 soaks/hour, with an annual use of just 12.9 hours/year. 23 The 

NONROAD default activity is 25 hours/year, implying somewhat larger yards (and possibly 

longer growing season) than the average in the ARB study, so the soaks/hour has been reduced 

somewhat to 2.0 soaks/hour. The commercial lawnmower value of 0.5 soaks/hour is taken 

directly from the ARB study. 

For the remaining equipment, values were estimated based on engineering judgment 

regarding how these equipment are likely used. An estimated lower bound is 0.125 soaks per 

hour of use, which is equivalent to 1 soak per 8 hours of use. A likely upper bound is 12 soaks 

per hour of use, which is equivalent to something used briefly on any given day, but long enough 

to warm up for 5 minutes, which would mean 1 soak per 0.083 hours of use. 

The upper limit for number of starts is 260 starts/year (based on 5 days/week and 52 

weeks/year). For each equipment type, starts/year is calculated by multiplying starts/hour and 

hours/year. If the resulting starts/year is greater than 260, the starts/year is reset to 260 and the 

starts/hour estimate is adjusted downward accordingly. This check and adjustment was done 

outside the model. The starts/hour estimates in the spillage.emf file already contain these 

adjustments. 

Since the activities for off-road motorcycles and ATVs are in units of miles/year, the hot 

soak inventory for this equipment is estimated by multiplying the hot soak emission rates in 

g/start by starts/mile and miles/year activity information. As shown in Table H5, there are 1.00 

starts/hour assumed for recreational equipment. To convert to units of starts/mile, the starts/hour 

are divided by the average speed in miles/hour. The average speed for ATVs is 9.6 miles/hour, 

which is a weighted average for utility and sport ATVs. The average speed for off-road 

motorcycles is 20 miles/hour. The resulting starts/mile values used in the model are 0.1042 

starts/mile for ATVs and 0.0500 starts/mile for off-road motorcycles. 

Assignment of Small SI Emission Factors to Equipment Types 

The small SI emission factors were then mapped to other applications based on similar 

characteristics of the equipment. The ARB mapping scheme19 is used with minor modifications. 

We use the generator/welder emission factor rather than the forklift for several applications (i.e., 

for signal boards/light plants and bore/drill rigs). We also use the lawnmower emission factor 

rather than the leaf blower for snowblowers. The assignments by SCC are given in Table H6.
