     equations.  The emissions presented in this document are the basic exhaust
     emissions, the crankcase and evaporative HC emissions, January 1 basic
     exhaust emission levels, and idle exhaust emissions.  Further, non-methane
     HC fractions  and particulates are presented.   In addition to the standard
     test procedure emissions, emission correction  factors are presented  to
     adjust  the emissions for various ambient and vehicle usage conditions  such
     as speed,  temperature, and humidity for NOx.

                              INTRODUCTION
This  document officially  revises  all  previous  highway mobile  source
emission factors  (AP-42)  documents.   This document  includes information
on particulate emissions,  and  diesel powered vehicle  and truck emission
factors.   Further,  this document  will  be periodically  revised  as the
emissions and in-use vehicle operational  characteristics  vary from  those
presented.    This  document  also   summarizes   the  detailed  background
document which  describes  the  data  and  derivation  process  for  all the
emission factors contained herein.   As such,  the only specific reference
for this document is  as follows:

     Derivation  of  the  Highway Mobile  Source  Emission  Factors,  April
     1981,  EPA 460/3-81-007.

A.  PURPOSE

This  document was  generated  to  present  more  recent  emission factor
information for  highway  mobile sources.   As such,  the March 1978 Mobile
Source  Emission  Factors;  For  Low-Altitude Areas  Only,  EPA-400/9-78-006
and Mobile Source Emission Factors,  EPA-400/9-78-OQ5 (MSEF) documents are
outdated.

B.  MAJOR DIFFERENCES FROM 1978 MSEF

The differences  between  the  emission factors presented  in this  document
and the March,  1978,  MSEF documents are  numerous.   The differences are
listed below:

     1)  Calculation Methodologies

         a)    The emission factors  are  calculated  for  a January 1 date
               instead of a July 1 date.
         b)    Crankcase  and  evaporative  HC  emissions  are  given   by
               component (crankcase,  diurnal,  and hot soak losses).
         c)    A  single  speed  correction  factor is  now  applied  to the
               entire trip cycle.   Previously,  a speed correction factor
               was applied to each of the three  operating  modes.
         d)    Temperature effects  are evident  on  all  three pollutants
               and operating modes as opposed  to only HC and  CO during
               the cold start mode.
         e)    The use of  air  conditioning is a function  of a discomfort
               index as opposed to an estimate.
         f)    The HDV  power  to displacement emission correction factor
               is no longer available.
         g)    A different approach  is used to estimate the  future in-use
               vehicle fleet  emissions.

     2)  Emission Data

         a)    Particulate emissions are  included.

                                   xi

-------
         b)    Emissions for  two  new vehicle  types,  LDDV  and  LDDT,  are
               included.
         c)    The HDV  emissions  are based  on the transient  cycle  test
               procedure.
         d)    More evaporative HC emission data are included.
         e)    More basic  exhaust emission  data  for  every vehicle  type
               are incorporated,  usually  for the latest  model  years  and
               across  wider mileage range.
         f)    Additional  idle emissions data  for every vehicle type  are
               used.
         g)    More current travel  weighting fraction data  (registration
               mix and mileage accrual)  for each vehicle type are used.
         h)    New non-methane HC  data are included.
         i)    More temperature  correction  factor  data  for  light  duty
               gasoline powered vehicles are incorporated.
         j)    New data for  air  conditioning  effects on  emissions  are
               utilized.

     3)  Regulations

         The emission  rates for  the  1981 and  later  model year vehicles
         reflect  the   emission   standards  and  regulations  that   were
         projected at  the  time of  this update.

In summary, all of the  changes  have  an  impact on the  calculated emission
factors.   To  illustrate the  differences,  nine figures  are given.   Each
figure  represents  emissions   at  an  average  speed  of  19.6   mph,  a
temperature of 75F, and operating mode VMT  percentages of  20.6% for cold
start and  27.3%  for hot start.  The  nine  figures  are grouped into  three
sets: 1) low altitude non-California, 2) California,  and  3)  high altitude
non-California emissions  for  January 1 of  calendar  years  1970  through
1999.   The  figures represent  the  emission levels for all eight  vehicle
types combined.  Each set  of  graphs is  composed of the  three pollutants:
non-methane HC,  CO, and NOx.   The  emissions predicted  by  the  1978 MSEF
methodology were generated  by the MOBILE1 computer model.  The emissions
predicted  by  the  1981  'AP-42 methodology  were generated  by the  MOBILE2
computer model.

C.  DOCUMENT ORGANIZATION

This  document  presents  the  highway  mobile  source  emission  factors  in
three major parts.  These  three  parts refer to the  three  regions of  the
country:  1) low  altitude  non-California,  2) California,  and   3)  high
altitude non-California regions.

Each  part  presents  highway mobile  source  emission  factors  for eight
vehicle  types.    The   eight  vehicle  types  are  1)  light   duty  gasoline
powered vehicles (LDGV), 2) light duty gasoline powered trucks with gross
vehicle weight (GVW) less than 6,001  Ibs.  (LDGTl), 3) light duty  gasoline
powered trucks with GVW less than 8,501  Ibs.  but  greater than 6,000  Ibs.
(LDGT2), 4) heavy  duty gasoline powered vehicles (HDGV),  5) light  duty
diesel  powered  vehicles  (LDDV),  6) light  duty   diesel  powered  trucks
(LDDT), 7) heavy duty  diesel powered  vehicles (HDDV),  and  8) motorcycles
(MC).  Light duty vehicles  and  automobiles  are synonymous.

Chapters 1  through  8  present the emission factors for  the low  altitude
non-California vehicle  types.   Each  of  these eight  chapters  is  divided
into  four  sections:  1)  Introduction, 2) Emissions,   3)  Travel Weighting
Fractions,  and 4) Emission Correction Factors.  The first section defines
the  vehicle  type,  the  basic exhaust  emissions test procedure,  and  the
generalized  equations  for  calculating  emission factors.    The  second
section  presents   the  basic  exhaust   emission   rates,  crankcase   and
evaporative HC emission levels,  January  1  basic exhaust emission levels,
and  idle  exhaust  emission   rates.   The  third  section  details   the
distribution information  required  for  the  travel  weighting  fractions.
The  last section  explains  how the  basic exhaust  emissions are corrected
for various ambient and vehicle usage conditions.   Chapter  9 presents the
emission factors for  the California vehicle  types.   The emission factors
for  the  high altitude  non-California vehicle  types are  presented  with
Chapter  10.   The tables  referenced  in  each of  these  ten chapters  are
given in Appendix E.

In  addition  to  the ten  chapters,   seven appendices  are given with  this
document.  Appendix A presents  the  emission  standards  assumed  in  this
document.  Appendix B illustrates how the total vehicle-miles-traveled  by
the  highway mobile  source  fleet   is apportioned  among  the  individual
vehicle  types.    Appendix  C  gives  the  calculation procedure  used  to
combine  the emissions of  the  two  light  duty  gasoline  powered truck
classes.  Appendix  D  presents  the methodology for calculating the  travel
weighting  fractions and the mileage accumulation distribution for  each
vehicle  type.   Appendix E presents  the  emission factor  tables for  each
vehicle type and region.  Appendix  F gives an example on how to calculate
the  emission  factors.   Appendix   G  presents emission   levels   of   all
vehicles combined under various ambient and usage  conditions.

Computing  the  emission  factors  is  complex  and  time  consuming.   It  is
recommended that  a computer program be used to  calculate the  emission
factors.   The  EPA has developed a  computer  program, MOBILE2,  that  will
perform  the  calculations using  the  emission  factors  presented  in  this
document.  The MOBILE2 computer  program  and  user's guide can be  obtained
from  the National Technical Information Service  (NTIS),  U.S.  Department
of Commerce, Springfield, VA 22161  (PB81 223067).  Phone:  (703) 487-4650.

D.  VEHICLE INSPECTION AND MAINTENANCE PROGRAM

If an annual motor vehicle inspection and maintenance (I/M) program is in
effect  in the  area  for  which  emission factors  are  being  calculated,
emission reduction credits can be taken.

The methodologies  for determining the I/M  credits are  contained  in the
Derivation  of  I/M  Benefits  for Pre-1981  Light-Duty  Vehicles for  Low
Altitude,  Non-California   Areas,EPA-IMS/81-4andDerivation  of  I/M
Benefits   for   Post-1980   Light  Duty   Vehicles   for   Low  Altitude,
Non-California Areas, EPA-AA-IMS/81-2.The MOBILE2 computer program can
apply  these low  altitude  non-California  I/M  credits  to  the emission
estimates.

The emission reduction credits attributable to an annual I/M  program vary.
according to the  type of  program in effect.   The  MOBILE2  credits  of an
I/M program depend upon the  following six factors.

    1)   The estimated  first year failure  rate  (stringency  factor)  for
         the pre-1981 low  altitude non-California LDGVs (or other vehicle
         types with similar emission control technologies).   The pre-1975
         vehicles  are  labeled   Technology   I  vehicles  and  1975-1980
         vehicles are labeled Technology  II vehicles.
    2)   The success  rate in identifying 1981 and later  model year low
         altitude  non-California  LDGVs   operating  under  rich  failure
         conditions (the  identification rate  of Technology IV  vehicles).
         Technology III is not defined in MOBILE2.
    3)   The vehicle  types  affected by the  I/M  program: LDGV;  LDGV  &
         LDGT1; LDGV & LDGT2; or LDGV, LDGT1,  & LDGT2.
    4)   The calendar year  being analyzed  and  the  calendar year the I/M
         program is implemented.
    5)   The  presence  or  absence   of   an  adequate  mechanics training
         program.
    6)   The model years involved in  the  I/M program.

E.  REACTIVE VS.  NON-REACTIVE HYDROCARBON EMISSIONS

Available  scientific  evidence  indicates  that  methane  and   a  few other
non-reactive organic  compounds  do not contribute  significantly to ozone
formations.  EPA1s  Volatile  Organic Compound  policy,  published  in  the
Federal Register on July  8, 1977, allows a  limited number of  compounds,
including methane, to be  excluded from control  actions.  States have  been
advised  that they  should  exclude these compounds  from baseline emission
inventories  that  are  to  be used for  control  strategy development  for
ozone.

Although motor vehicles are  regulated directly  by  the  Clean Air Act on  a
total hydrocarbon basis (rather than on  a  "reactive" hydrocarbon basis),
it is  appropriate,  when estimating  ozone levels,  to consider  only those
motor  vehicle  emissions   which  will react   to  form   ozone.   However7'
consideration must  be given  to the  format of any associated  stationary
source  emission  inventory  so  that   mobile  source  and  stationary  source
emission inventories are consistent  in their  exclusions.

                                  xxiii

-------
Prior to  the  introduction of catalyst  technology,  virtually all (93%  or
greater)  mobile source  HC  emissions  were  considered  reactive.'  With
present and future catalyst  technology,  the methane (i.e.,  non-reactive)
fraction of total hydrocarbon emissions  is  Increasing.   Estimates of  the
methane  percentages  applicable  to  each  vehicle  category  are  given  in
Table 1.

While  the  MOBILE2  computer  program  can  calculate  either   total   or
non-methane hydrocarbon emissions,  all HC  emission factors presented  in
this document are total hydrocarbons.

F.  PARTICULATE EMISSIONS

The  particulate  emissions for  total  exhaust,  lead,  sulfate,  and tire
particulates are presented in Table 2 for all low altitude and California
vehicle/technology types.   Similarly,  the  particulate  emission factors
for high altitude vehicle/technology types are presented  in Table 3.

Where applicable,  total exhaust  particulate from  non-catalyst  vehicles
using leaded  gasoline is  normalized to.  2.0 grams/gallon  Pb.  Further,
taking  an intermediate  value  from  experimental  data,  we  assume lead
particulate to be  30%  of total exhaust particulate  as  measured  over the
FTP  urban  cycle  from non-catalyst vehicles using  leaded gasoline.  This
assumption is  consistent with calculations  based  on fuel  lead  content,
vehicle fuel economy, and percent  total lead  emitted  as particulate.

No information is  available  on  total exhaust particulate from HDGV using
unleaded gasoline.  As a result,  the emission  factor is estimated by the
following:
Total ExhHDGV(Unleadedj - Total Exhu^d^,.^,,,!)  Total  Exh  HDV  (Leaded)
                          Total ExhLDV(Leaded)

                             "  32  (420) - 56  mg/mile
                                240

No measured data could be found on total  exhaust, lead,  sulfate, and  tire
particulate  emissions  from  light duty  gasoline powered  trucks  (LDGT).
Based on  engineering Judgement that  the differential  in average weight
and average  fuel  economy between LEGTs  and LDGVs is minor  and that  the
two vehicle  classes  are similar  within  individual technology  subgroups,
it is assumed  that  LDGT particulate emission  factors  are equal to  those
of LDGVs.

For light  duty diesel powered trucks  (LDDT),  the limited data  available
indicates  no difference  in exhaust particulate  levels  between LDDTs  and
LDDVs.  Furthermore, exhaust particulate  standards for LDDVs and LDDTs to
be imposed on  1982  through  1984 model  years  are  identical and  roughly
equivalent to  currently measured levels.   it  is  therefore  assumed  that
th.e standard will be met, and the standard  is  selected as  the  appropriate
emission factor for all model  years through  1984.   For  1985 and  later
model years, it is similarly assumed that the  reduced standards  for  LDDVs
and LDDTs  will be met,  and these are  taken  as  the  applicable emission
factors.

The tire wear rate of 0.085 grams/mile/tire estimated for  LDVs  is  assumed
for all vehicle  types  due  to  lack of  data.   Tire  particulate is  then
computed by  vehicle  type based on the  average number of  wheels and  the
estimate that 55% of the tire wear becomes suspended particulate.

Total exhaust  particulates  from  all diesel  powered  vehicles  at  high
altitude are estimated to increase by 39% over  the levels at  low
                                   xxv

altitude.  Sulfate levels at  high altitude are estimated  to decrease by
68% over the levels at low altitude.  Due to insufficient data, all other
particulate emission  factors  at high altitude  are assumed  equal  to low
altitude factors.

                  LIGHT DUTY GASOLINE POWERED VEHICLES

l.A  INTRODUCTION

Because  of  their widespread  use,  light  duty gasoline  powered vehicles
(LDGV; passenger cars) are responsible for a large share of air pollutant
emissions in many  areas  of the  United States.   A LDGV  is  defined to be
any gasoline fueled motor vehicle designated primarily for  transportation
of persons  and having a  capacity  of  12  persons  or  fewer.   Substantial
research effort  has been  expended to  accurately  characterize emissions
from these  vehicles.   EPA's on-going  program to  collect  in-use  vehicle
emissions was  instituted  a number  of years  ago  in  order  to estimate
emission levels.

In addition to  the methodologies  presented for  calculating  the  basic
exhaust  emission  levels  for  HC,  CO,  and  NOx,  data  are given  in  this
chapter  for   crankcase   and  evaporative   hydrocarbon  emissions,   and
emissions in  the  idle mode.   Information is  also given  regarding  the
emission correction factors and travel weighting  fractions.

I.A.I  Test Procedure

LDGV emissions testing is currently performed according  to  the  procedures
stipulated in  the  Federal  Register (42 FR 32954,  June  28,  1977)  and  the
Code of  Federal Regulations (40 CRF Part 86, Subpart B,  July 1,  1980).
The basic test conditions under which the  LDGVs  are tested  are as follows:

    1.  Ambient temperature range is 68F  to 86F.
    2.  Absolute humidity is adjusted  to  75 grains of water  per pound of
        dry air.
    3.  Average speed is  19.6 mph with 18% idle  operation.
    4.  Average percent  of  vehicle-miles-traveled  (VMT) in a. cold  start
        operation is 20.6%.
    5.  Average percent of VMT in a hot start operation is  27.3%.
    6.  Average percent of VMT in the stabilized operation is  52.1%.
    7.  Average trip length is 7.5  miles.

Additional elements  regarding the test procedure  that  are  reflected in
the emission estimates are as follows:

    1.  Air conditioning  not in use.
    2.  Car contains  driver and passenger   no  additional  passengers,
        luggage, etc.
    3.  Car is not pulling a trailer.

The test sequence for LDGVs is summarized  below:

    1.  Determine the weight of the vehicle.
    2.  Determine the road-load  (assuming level  road, no curves, no wind)
        which is a function of weight and  frontal area.

-------
                                   -2-

    3.  Precondition the vehicle  (i.e.,  vehicle  is  briefly driven).
    4.  Place the  vehicle  in an ambient  temperature environment  between
        68F and 86F with its  engine off  for  at least  12  hours.
    5.  Push the vehicle onto a dynamometer.
    6.  Start the engine and begin  collecting  exhaust emissions.
    7.  Emissions  for  the  first  505  seconds  are  collected  for  test
        segment  #1.   The mileage  driven  is  3.59  miles  with an  average
        speed of 26 mph.  This  is the cold start portion of the test.
     8. Test segment #2 collects  emissions for  the next 870  seconds.   The
        engine  is  not  turned  off  between Steps 7  and  8.   The  mileage
        driven  is  3.91  miles and the average  speed  is 16 mph.  This  is
        the stabilized portion  of the test.
     9. The engine is turned off.
    10. The engine remains off  for  10 minutes.
    11. The  car  is  restarted,  the first 505 seconds  are  rerun,   and
        emissions  are  collected  for test .segment #3.   This  is the  hot
        start portion of the test.
    12. The grams of each pollutant are  determined  for  each test segment.
    13. NOx emissions are adjusted  for humidity.
    14. The basic exhaust emission  level in grams per mile is computed.

1.A.2  General Emissions Calculation Equations

This  section  discusses  the  emission  estimates  for  the  LDGVs:   Basic
exhaust  emission rates, crankcase and  evaporative RC  emission  levels,
January 1  basic  exhaust  emission  levels,   and  idle  exhaust  emission
rates.  The emission standards are given in Section A.1.1 of  Appendix  A.
The  emissions  reflect  vehicles  which  have   received   typical   in-use
maintenance.  Further,  the  vehicles are not  involved in an I/M program.

I.B.I  Basic Exhaust Emission Rates

The basic exhaust emission rates for LDGVs were  derived  for  the most part
from in use vehicle data.  The  basic  assumption in the derivation  of  the
emission  rates  is  that  emission levels  change  linearly  as  vehicles
accumulate  mileage.   The   rates  are   dependent  upon  two  estimated
variables:   (1) zero   mile   emission   levels   and   (2) the   emission
deterioration rates.  The zero mile emission  levels are  the  average grams
of  pollutants  emitted  by  the  vehicles at  zero miles.   The  emission
deterioration  rates adjust the  zero  mile levels  as vehicles accumulate
mileage.

The basic exhaust emission  levels are  calculated from a linear function:

    BERipn -    ZMLip  + DRip  * Mln

where the lower case letters  are subscripts and

-------
                                   -4-

    BERipn "    The  basic  exhaust  emission  level,  in  grams/mile,   for
                model year 1  and pollutant  p,  on  January  1 of  calendar
                year n.

    ZMLip =     The estimated  zero mile  emission  level,  in  grams/mile,
                for model year i and pollutant p.

    DRip       The estimated emission deterioration rate,  in  grams/mile/
                10,000 miles,  for model year  i and pollutant p.

    Min =       The model  year i  cumulative mileage,  divided by  10,000
                miles, on January 1 of calendar  year n.

The basic  exhaust  emission rates  are presented  in Table 1.1.1A for  the
different LDGV model year groups and pollutants.

1.B.2  Crankcase and Evaporative HC Emission  Levels

In  addition  to  the  basic  exhaust  HC  emission  levels,  crankcase  and
evaporative  HC emissions  need to  be  included.    Crankcase  HC  emission
levels result from the crankcase as the engine is  running.   The  two major
sources of evaporative HC emissions are hot  soak  and diurnal losses.   Hot
soak losses are generally produced as  fuel evaporates from  the  carburetor
system  at  the end of a  trip.  Diurnal  changes  in ambient  temperature
result  in  expansion of  the air-fuel  mixture in  a partially filled  fuel
tank.   As   a  result, gasoline vapor  is  expelled into  the  atmosphere.
Crankcase and  evaporative HC  emission levels are calculated according  to
the following equation:

    CCEVi =     (HSKi *  TPD + DNLi)/MPD + CCi

where the lower case letters  are subscripts and.

    CCEVi =     The  estimated  crankcase  and  evaporative  HC   emission
                level, in grams/mile,  for model  year i.

    HSKi =      The estimated hot  soak HC  emission level,  in  grams/trip,
                for model year i.

    TPD =       The average number of trips/day.

    DNLi =      The estimated diurnal HC  emission  level,  in  grams/day,
                for model year i.

    MPD =       The average miles driven per  day.

    CCi =       The estimated crankcase HC emission  level,  in  grams/mile,
                for model year i.

Crankcase  and evaporative HC  emission  levels  are summarized  in  Table
1.1.IB.   This table  presents  each  variable described above  for  every
model year.

                                   -5-

1.B.3  January 1 Basic Exhaust  Emission Levels

The  basic exhaust  emission levels  for  the latest  20  model  years  on
January 1, 1970 through 1993,  are  given in Tables  1.1.2A through 1.1.2C
for HC, CO, and NOx,  respectively.   The HC basic exhaust emission levels
reflect  total,  rather  than  non-methane,  HC  emissions  and  exclude
crankcase and evaporative  HC emission levels.

l.B.A  Idle Exhaust Emission Rates  (Hot Stabilized)

Estimates  of   emissions  expelled  from  the  automotive  fleet  during  a
vehicle's  idle   operating  mode   have  become   a  major   concern  in
transportation control plans,  environmental  impact statements, and  state
implementation  plans.   Examples  of  extended  idle  time  are  waits  at
shopping centers, airports,  sport complexes, and drive-in window service
businesses.   The  emission  estimates  presented  in this  section reflect
engines operating in a hot stabilized condition.

The idle exhaust emission  rates  are expressed  in  units of emissions per
unit  time  (grams per minute)  as  opposed  to the  basic exhaust emission
rate units (grams  per mile).  The LDGV  idle exhaust  emission levels are
calculated from  the  estimated zero  mile emission levels  and emission
deterioration  rates  given In  Table  1.1.3.   The idle  emission level (in
units  of  gm/min)  is  calculated  from  a linear function similar  to the
basic  exhaust  emission  level function given in Section I.B.I.  The idle
emission function is lERipn -  ZMLIDLip + DRIDLip  * Min.  The  definition
of the terms  in this equation are  almost identical to  those in Section
I.B.I, except  these  are idle emissions and are expressed in  grams/minute
for  the zero  mile  levels  and  grams/minute/10,000 miles  for  the  idle
emission deterioration rates.

l.C  TRAVEL WEIGHTING FRACTIONS

The  LDGV  travel  weighting  fractions  are  the  individual   model  year
proportions of the  total LDGV VMT.   To  generate the  travel  weighting
fractions, three distributions, described in detail below, are  required:
(1)  the fleet  annual mileage accumulation'rate  distribution,  (2) the
registration  distribution,  and (3)  the  estimated fleet  sales fraction
distribution (to account  for the  proportional  increase of diesel powered
vehicles).

The  travel weighting  fractions  in  this  document  reflect  a  January  1
evaluation date.  For the  LDGVs,  the model year is  assumed  to begin  sales
on the October 1 preceding,  the corresponding calendar year.   Further, it
is assumed th~ the vehicles are sold  and accumulate mileage  according to
a  uniform  distribution  (see  below).   These  assumptions   permit the
estimation of  the  January  1  fleet  mileage accumulation  rate  distribution
and the January 1  registration distribution  from July 1  information.  An
example  of  the  travel  weighting  fraction   calculation  is   given  in
Table 1.1.5'.

-------
                                   -6-

l.C.l  Fleet Annual Mileage Accumulation Rate Distribution

A given  vehicle  is estimated to  travel  according to  the  annual mileage
accumulation  distribution given  in  Table  1.1.4A.   For  example,  the
vehicle in its first year travels 14,440  miles  at a uniform rate.  In its
second year,  it  travels  13,900 miles at  a uniform rate.   Finally in its
20th year, it travels 4,300 miles  at a uniform rate..

The annual  fleet mileage accumulation  rate distribution is  derived from
the  annual   mileage  accumulation  rate  distribution   for  individual
vehicles.  This  derivation averages out  the effects  of  purchase date.
The derivation is described in Appendix D, and the resulting distribution
is given in Table 1.1.4A.

l.C.2  Model Year Registration Distribution

Table  1.1.4A also presents  the  estimated LDGV  model  year  registration
distribution  fractions.   These  fractions  are  the individual  model year
proportions  of  the entire LDV  fleet (both  gasoline and  diesel powered
vehicles  combined).   The  registration distribution is  based  on July 1
figures  and  is  transformed  to  January 1  figures  according  to  the
procedure  in  Appendix  D.    The  January 1   LDV   fleet  registration
distribution is presented in  Table 1.1.4A.

l.C.3  Fleet Sales Distribution

Assuming  that  diesel powered vehicles  will become  more  prominent,  the
travel weighting fractions need  to  account for them.  It  is estimated
that gasoline powered vehicles will account  for  proportionately fewer of
the  future  light  duty  vehicle  model  year   sales  according  to  the
distribution given in Table  1.1.4B.   The  distribution  is  anticipated to
stabilize  in 1991,  with  80 percent of  the _LDV  sales  being gasoline
powered vehicles.

The fleet sales distribution  is used in the travel weighting fractions to
account for  the  influx  of diesel.  The  travel  weighting fractions change
every  January 1  in  calendar years 1975  through  2010.   Prior  to 1975,
diesels  are considered  to  be  an  insignificant proportion  of  the  LDV
fleet.  Further,  even though  the fleet sales distribution is predicted to
stab'lize  in 1991,  the  travel weighting  fractions  require  20  years to
stabilize.   From that time  on  (201CH-),   the travel  weighting fractions
remain constant.

l.D  EMISSION CORRECTION FACTORS

The LDGV  basic  exhaust emission  levels are  based on  test results under
the standardized conditions defined in Section I.A.I.  However, the basic
exhaust  emission  levels  are affected   by  ambient   and  vehicle  usage
conditions  which  differ  from   the  prescribed  test  procedure.   The
conditions under which emissions are known to vary are the average  speed,
ambient  temperature,  fraction of VMT in cold  and  hot  start operating
modes,  use  of   air  conditioning,  carrying  of  an  extra  load,   trailer
towing,  and  humidity.    Emission  correction  factors  are  available to
compensate for these conditions.

-------
                                   -7-
l.D.l  Speed Correction Factor

The test procedure used  for  collecting the basic exhaust  emissions is a
driving cycle with an  average speed of 19.6 nph.   For those  situations
where the average speed of the vehicle deviates  from this  value, a speed
correction factor is applied.   This speed correction  factor  will now be
examined and  later  incorporated into  the' Ripstwxn  correction  factor in
Section l.D.3.

The speed correction factor is given in Table  1.1.6. It is symbolized as
SCFipsxw where the lower case letters are  subscripts  and

    SCFipsxw   The   speed  correction  factor   for  model  year  i  and
                pollutant  p   at  the  average  speed  of  s.   This  is
                normalized to the speed associated with a cold start mode
                VMT  fraction  x and  a hot start mode VMT fraction w

The user  is  cautioned that  this  correction  factor  is  only  valid  for
speeds in the 5 through 55 mph range  since the regression equations were
based on speed data in that  range.   Extrapolations  to speeds beyond this
range should not be  made.

1.D.2  Emission Temperature Correction  Factor

The  established  LDGV  emissions  test  procedure   requires  an  ambient
temperature between 68F and 86F.  For situations which differ from  this
temperature range, an  emission temperature  correction factor is  applied.
The emission  temperature correction factors  were  based  upon  data  from
several in-use vehicle  emission  test programs:  EPA,  Bureau of the  Mines,
Bartlesville Energy Research  Center,  Canadian Environmental  Sevices, and
Gulf Research.  Analysis  of  the data  indicate  that  all three pollutants
(HC, CO,  and NOx)  in  all three  test segments  (bags) are  affected by
temperature.   Therefore,  a   separate  emission  temperature correction
factor is given for each bag and pollutant in Table  1.1.7A.   The  emission
temperature correction factor equation  is  as follows:

    TCFipbt -   EXP(TCipbtt(T - TT))

where the lower case letters  are subscripts and

    TCFipbt    The  emission temperature correction factor for model  year
                i, pollutant  p, test segment b,  and ambient temperature t

    EXP =       The exponential function.

    TCipbtt =   The  temperature  correction factor coefficient  for model
                year  i,  pollutant  p, test   segment   b,   and   reference
                temperature tt.

    T "         Ambient temperature (Fahrenheit).

    TT =        Reference temperature which equals 67.5F  when T is  less

1.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A single  emission correction factor  called  Ripstwxn adjusts  for  speed,
temperature,  and  hot/cold  start  operating-mode  conditions  that   differ
from  the  basic  test  procedure.    A vehicle  will  usually  emit more
emissions in a cold start mode than  in a  stabilized or  a hot start mode.
As such, vehicles will  emit more  pollution after  an  extended engine off
period  than vehicles  that  have not  set  long  enough to be in  the cold
start mode.   As  a result,  the operating  mode  is  a necessary element  of
this correction factor.

An  integral  part  of  the  operating mode  portion  of   Ripstwxn  is  the
normalized  bag fractions.   The  normalized bag  fractions adjust Ripstwxn
for emissions attributable  to  each  operating mode.   These  fractions for
LDGVs are given in Table 1.1.7B.
The Ripstwxn correction factor is  defined as  follows:

    Ripstwxn =  ((TERM1 + TERM2 +  TERM3)/DENOM)*SCFlpswx

where the lower case letters are subscripts and

    Ripstwxn =  The  speed/temperature/operating-mode  emission  correction
                factor for  model  year i,  pollutant  p, average speed  s,
                ambient temperature t,  fraction of VMT  in  a cold  start
                operating mode  w, and  fraction of  VMT  in  a  hot  start
                operating mode x;  on January  1 of calendar  year  n.

    TERM1 =     W * TCFiplt  *(Bipl + Dipl * Min)

    TERM2 =     (l-W-X)*TCFip2t *  (Bip2 + Dip2 * Min)

    TERM3 =     X * TCFip3t  *(Bip3 + Dip3 * Min)

    DENOM =     BipO + DipO  * Min

    SCFipswx =  The emission speed correction factor for model year  i  and
                pollutant p  at  the average speed of  s, normalized to  the
                speed associated  with a cold start  mode  VMT fraction  x
                and a hot start mode VMT  fraction w.

    Bipb =      The  normalized bag  fraction  intercept   coefficient  for
                model  year  i,  pollutant  p,  and  test  segment  b  (test
                segment 0 is the entire  basic test  procedure).

    Dipb =      The normalized  bag fraction  slope coefficient  for  model
                year i,  pollutant  p,  and  test segment b  (test segment  0
                is the entire basic test  procedure).

    Min =       The  fleet  cumulative  mileage  for   model  year   i   on
                January 1 of calendar  year n.

1.D.4  Air Conditioning Correction Factor

The  LDGV emissions  can  be significantly  affected  by  the  use  of  air
conditioning.  The  air conditioning  correction factor  coefficients  are
based on data from vehicles tested at several different temperatures with
the  air conditioner  on.   These  correction, factors are  given  in Table
1.1.8A.  The general correction factor equation  is  as follows:

    ACCFipt -   U*Vi ([Aip + Bip * (T -  75)]  -1) +1

where the lower case letters are subscripts and

1.D.5  Extra Load Correction Factor

The  basic  exhaust  emission  rates are  based  on the  "typical"  vehicle
weight  with a  driver and  passenger,  vehicle  fuel,  and  other  liquids.
There are, however, situations in which vehicles have extra weight due  to
additional  passengers,  luggage,  etc.   In  these  events,  emissions are
known to change.

To apply the vehicle extra load correction factor found in Table  1.1.9  to
a specific  situation, it  is  necessary  for a user to  have an estimate  of
the  percentage  of LDGV  VMT accumulated  with an additional  500  pounds.
The  correction  factor   for  extra  load  is  computed  according  to the
following equation:

    ELCFip >    (XLCip -1) * U + 1

where the lower case letters are subscripts  and

    ELCFip =    The extra  load correction  factor for  model  year  i and
                pollutant p.

    XLCip =     The extra  load correction  factor coefficient  for  model
                year i and pollutant p.

    U          The fraction of  LDGV  VMT accumulated with  an extra  load
1.D.6  Trailer Towing Correction Factor

As with  the  extra load correction factor,  the trailer towing  correction
factor will adjust LDGV emissions  for usage conditions which differ  from
the basic  test  procedure.   It  has been determined  that  towing a  trailer
will  affect  a  vehicle's emissions.   As  such,  a  correction  factor is
available  to adjust  LDGV  emissions when  a trailer is being towed.   The
correction factor coefficients  given In  Table  1.1.10  are valid  for a
trailer weight of 1000 pounds.   This  correction factor is computed  by  the
following equation:

    TTCFip -    (TTCip - 1)  * U + 1

where the lower case letters are subscripts and

    TTCFip     The  trailer towing correction factor for model year i  and
                pollutant p.

    TTCip -     The   trailer towing   correction  factor  coefficient   for
                model year i and pollutant p.

    U =         The   fraction of  LDGV  VMT  accumulated  while  towing a
                trailer (0<=lk=l).

1.D.7  NOx Humidity Correction Factor

The NOx  emission  factors  are  normalized to 75 grains  of  water per  pound
of  dry air.   In  order  to adjust  NOx  emissions  to  different  humidity
conditions, a multiplicative correction factor is available.  The  formula
for the correction factor is given below, and is applicable  for all  model
years:

    HCF -   1.0 - .0047 * (H - 75)

where:

    HCF =   The NOx humidity correction factor.

    H   -   Humidity level in grains of water  per pound of dry air
            (20<-H<-140).

                  LIGHT DUTY GASOLINE POWERED TRUCKS I

2.A  INTRODUCTION

This  chapter  presents  the  emission  factors  for  light  duty  gasoline
powered trucks with  a  gross  vehicle weight  (GVW)  rating of 6,000 pounds
or  less  (LDGT1).  A LDGT1 is  defined  to  be  any  gasoline fueled motor
vehicle designed  primarily for transportation  of  property and rated at
6,000  pounds  GVW   or  less.   Although  LDGTls  have   a   load  carrying
capability that  exceeds  that  of passenger  cars,  they are  typically  used
for personal transportation;  as passenger car substitutes.

As with Chapter  1,  this  chapter divides  the emission factors  into three
major  sections:  (1)  Emissions, (2)  travel  weighting  fractions,  and  (3)
emission correction factors.

2.A.I  Test Procedure

The test procedure used for determining  the LDGTl basic  exhaust emissions
is almost  identical  to  the LDGV test  procedure.   The difference  between
the two  test procedures is  primarily  the  road-load horsepower  setting.
The summary  of the  test  procedure in  Chapter  1 is  correct  for  LDGTls.
Therefore, refer to Chapter 1 for a brief overview.

2.A.2  General Emissions  Calculation Equations

The generalized  calculating equations  presented in  Chapter  1 are  also
valid  for   the   LDGTls.    Although  the  emissions,   travel  weighting
fractions,  and  emission  correction   factors   levels  for  LDGTls   are
different from the LDGVs,  all of the equations  are  identical.

2.B  EMISSIONS
This  section  discusses  the  LDGTl  emission  estimates:   Basic   exhaust
emission rates,  crankcase  and evaporative HC emission  levels,  January  1
basic  exhaust  emission  levels,  and  idle exhaust  emission  rates.   The
emission  standards  are given in  Section  A.1.2  of  Appendix  A.   The
emissions reflect  trucks which have received typical in-use  maintenance.
Further, the trucks are not involved in an I/M program.

The discussions  of the different emissions  in Chapter 1  are also valid
for  the LDGTls.   Therefore,  the  discussions  will  not  be reiterated.
Please  refer  to Chapter  1  for  the discussions  that  correspond to  the
subsections below.

2.B.I  Basic Exhaust Emission Rates

The LDGTl basic  exhaust emission rates are  given in Table 1.2.LA.   This
table  presents  the   LDGTl   zero  mile  emission  levels  and   emission
deterioration rates for  every model year.  The emissions are measured in
grams per mile.

-------
                                  -13-

2.B.2  Crankcase and Evaporative  HC  Emission Levels

The LDGT1  crankcase  and evaporative RC emission levels  are presented in
Table 1.2.IB.  This table presents the emissions for every model year and
crankcase and evaporative HC component: diurnal  losses,  hot soak losses,
and crankcase losses.

2.B.3  January 1 Basic Exhaust  Emission Levels

January  1,  1970 through  1993, LDGTl  basic  exhaust emission  levels are
given in Tables 1.2.2A  through 1.2.2C  for  HC,  CO,  and NOx, respectively.
The  HC  basic  exhaust   emission  levels  reflect   total,   rather  than
non-methane, HC emissions and exclude crankcase and  evaporative HC levels.

2.B.4  Idle Exhaust Emission Rates (Hot Stabilized)

The LDGTl  hot stabilized  idle  exhaust emission rates are  given in Table
1.2.3.   These  emission levels  are  measured  in  grans  per minute  and
reflect engines operating in a  hot stabilized condition.

2.C  TRAVEL WEIGHTING FRACTIONS
The  LDGTl  travel  weighting  fractions  are  the  individual model  year
proportions of  the total  LDGTl VMT.   To generate  the  travel weighting
fractions, three distributions are required: (1) the fleet annual mileage
accumulation  rate  distribution,  (2)  the  registration  distribution,  and
(3)  the  estimated  fleet sales fraction distribution (to  account for the
proportional  increase  of  diesel powered  trucks).   The first  and second
distributions are  given in Table  1.2.4A, and the  third  distribution is
given in Table 1.2.4B.  More detailed information is available in Chapter
1 on these distributions.

The  travel weighting  fractions  in  this document  reflect  a  January 1
evaluation  date.   For  the  LDGTls, the model  year  is assumed  to begin
sales  on  the  October 1  preceding  the  corresponding  calendar  year.
Further, it is  assumed that the  trucks are sold  and accumulate mileage
according  to  a  uniform  distribution.   These  assumptions permit  the
estimation of the  January 1 fleet  mileage accumulation rate  distribution
and  the  January  1  registration  distribution from July 1 information.  An
example  of   the   travel  weighting  fraction  calculation   is  given  in
Table 1.2.5.

2.D  EMISSION CORRECTION FACTORS

The LDGTl  basic  exhaust emission levels are based  on test  results under
the  standardized  conditions defined  in  Chapter  1.  However,  the basic
exhaust  emission  levels  are   affected   by  ambient  and  truck  usage
conditions  which  differ  from   the   prescribed  test  procedure.   The
conditions under which emissions are known to vary  are the average speed,
ambient  temperature,  fraction  of  VMT  in cold  and hot  start operating
modes,  use of  air  conditioning,  carrying of  an  extra  load,  trailer
towing, and humidity level.  Emission correction factors are available to
compensate for these conditions.

-------
                                  -14-

The  LDGTls  correction  factors  are  based  on  the  LDGV   information.
Therefore, the  LDGT1 correction factors  are those from  the LDGV's, and
the LDGV discussions in Chapter 1 are valid for  the  LDGTls.

2.D.I  Speed Correction Factor

The test  procedure  used  for collecting the  basic exhaust emissions is a
driving cycle with  an average  speed  of  19.6 mph.  For  those  situations
where the  average  speed of the  truck deviates  from this  value,  a  speed
correction factor is applied.  The LDGT1 speed correction factor is  given
in Table 1.2.6.

2.D.2  Emission Temperature Correction Factor

The  established  LDGT1  emissions  test   procedure  requires an  ambient
temperature  between  68F   and  86F.   For  those  situations  where the
ambient  temperature  is  not  in  this  range,  an  emission temperature
correction  factor   is  applied.    Table  1.2.7A  presents   this  correction
factor for the LDGTls.

2.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A  single  emission  correction factor  called Ripstwxn adjusts for  speed,
temperature,  and  operating-mode  conditions that  differ  from  the   basic
test  procedure.    As  described   in  Chapter  1,   Ripstwxn  depends   on
normalized bag  fractions.   The LDGT1 normalized bag  fractions  are  given
in Table 1.2.7B.

2.D.4  Air Conditioning Correction Factor

The  LDGT1 emissions  can be  significantly affected  by   the use  of air
conditioning.  These  correction  factors  are given  in Table   1.2.8A.  The
fractions of LDGTls equipped with  an air conditioner,  by model year, are
given in Table 1.2.8B.

2.D.5  Extra Load Correction Factor

The basic exhaust emission  rates  are  based on the  "typical"  truck weight
with  a  driver  and  passenger,  fuel,  and  other  liquids.   There  are,
however,  situations  in which trucks have  extra weight due  to  additional
passengers, luggage,  load,  etc.   In these  events,  emissions  are known  to
change.

To apply the truck extra load correction factor found in Table  1.2.9 to a
specific situation,  it is necessary for a user to have an estimate of the
percentage of LDGTl VMT accumulated with  an additional 500 pounds.

2.D.6  Trailer Towing Correction Factor

As with  the  extra  load correction  factor,  the  trailer towing  correction
factor will adjust LDGTl emissions  for usage conditions which differ from
the basic  test  procedure.  The  correction factor  coefficients given  in
Table 1.2.10 are valid for a trailer weight of 1000  pounds.

for the correction factor is given below, and is applicable  for all  model

                  LIGHT DUTY GASOLINE  POWERED TRUCKS  II

3.A  INTRODUCTION

This  chapter  presents the  emission  factors  for  light  duty gasoline
powered trucks with a gross vehicle weight (GVW) rating between 6,001 and
8,500 pounds (LDGT2).  A LDGT2 is defined to be any  gasoline  fueled motor
vehicle  designed  primarily  for  transportation  of  property  and  rated
between 6,001  pounds and  8,500  pounds GVW,  inclusive.  This  vehicle type
is  required  since these  trucks were  classified  as  heavy  duty vehicles
through the  1978  model year.   Beginning with the  1979  model year, these
trucks have been considered as light duty  trucks.

In general, every  LDGV  section  and  subsection discussion in  Chapter 1 is
valid  for  this  chapter.   Therefore, these  discussions  will  not  be
reiterated.  Please  refer  to  Chapter  1 for  a  complete  discussion of the
sections and subsections of this chapter.

As with the other  chapters, the emission factors are  separated  into three
major sections:  (1)  Emissions, (2) travel  weighting fractions,  and (3)
emission correction factors.

3.A.I  Test Procedure

The test procedure used for determining the LDGT2  basic exhaust emissions
is almost  identical  to the LDGV test  procedure.   The difference between
the two  test procedures  is  primarily the road-load horsepower setting.
The LDGV test procedure summarized  in  Chapter 1  is  valid for the LDGT2s.

3.A.2  General Emissions Calculation Equations

Chapter 1  also presents  the  generalized  calculating equations that are
valid  for   the   LDGT2s.    Although   the  emissions,  travel  weighting
fractions,  and emission correction factors  for the  LDGT2s  are different
from the LDGVs, all of  the equations are identical.

3'.B  EMISSIONS

This section presents  the  LDGT2  emissions: Basic  exhaust emission rates,
crankcase  and  evaporative HC  emission levels, January  1  basic exhaust
emission levels,  and  idle  exhaust emission  rates.   The  pre-1979 model
year LDGT2 were  considered heavy duty vehicles; their emission standards
are given  in  Section  A.1.3  of  Appendix A.   The  1979  and  later LDGT2
emission  standards  are  given  in  Section  A.1.2  of  Appendix A.   The
emissions reflect  trucks  which  have  received typical in-use  maintenance.
Further,  the trucks are not involved in an I/M program.

3.B.I  Basic Exhaust Emission Rates

The LDGT2  basic  exhaust emission rates are  given  in Table 1.3.LA.  This
table  presents   the   LDGT2   zero   mile  emission  levels  and  emission
deterioration  rates  for every  model year.   The emissions are measured in
grams per mile.

3.B.2  Crankcase and Evaporative HC Emission Levels

The LDGT2 crankcase and evaporative HC emission levels are given in Table
1.3.IB.   This table  presents the  emissions  for  every  model year  and
emission component: diurnal  losses, hot soak losses, and crankcase losses.

3.B.3  January 1 Basic Exhaust Emission Levels

January  1,  1970 through  1993,  LDGT2 basic  exhaust emission  levels  are
given in Tables 1.3.2A through 1.3.2C for  HC,  CO,  and NOx, respectively.
The  HC basic  exhaust emission levels  reflect  total,  rather  than non-
methane, HC emissions and exclude crankcase and evaporative HC levels.

3.B.4  Idle Exhaust Emission Rates  (Hot Stabilized)

The LDGT2 hot  stabilized  idle exhaust emission rates are  given in Table
1.3.3.   These emissions  are  measured in  grams per  minute  and  reflect
engines operating in a hot stabilized condition.

3.C  TRAVEL WEIGHTING FRACTIONS

The  LDGT2  travel  weighting  fractions  are  the  individual  model year
proportions of the total LDGT2  VMT.  To  generate the  travel weighting
fractions, three distributions are  required: (1) the fleet annual mileage
accumulation  rate  distribution,  (2)  the  registration  distribution,  and
(3)  the  estimated  fleet  sales fraction distribution  (to  account  for the
proportional  increase  of diesel  powered trucks).   The first  and  second
distributions  are  given  in Table  1.3.4A,  and the  third  distribution is
given in Table 1.3.4B.  More detailed information is available in Chapter
1 on these three distributions.

The  travel weighting  fractions  in  this  document  reflect  a January  1
evaluation  date.   For the  LDGT2s,  the  model  year is  assumed  to begin
sales  on  the  October 1  preceding  the  corresponding  calendar  year.
Further, it  is assumed that  the trucks  are sold  and accumulate mileage
according  to  a  uniform distribution.    These assumptions   permit  the
estimation of  the  January 1  fleet  mileage  accumulation rate distribution
and  the  January 1  registration distribution  from July 1 information.  An
example  of  the   travel  weighting  fraction  calculation  is  given  in
Table 1.3.5.

3.D  EMISSION CORRECTION FACTORS

The LDGT2  basic exhaust  emission  levels are based  on test results under
the  standardized  conditions defined  in  Chapter  1.  However,  the basic
exhaust  emission  levels  are  affected   by   ambient  and  truck  usage
conditions  which  differ   from  the  prescribed  test  procedure.   The
conditions under which emissions  are known to vary  are the average  speed,
ambient  temperature,  fraction of  VMT  in  cold  and hot  start operating
modes,  use  of air  conditioning,   carrying  of  an extra  load,   trailer
towing, and humidity level.   Emission correction factors are available to
compensate for these conditions.

-------
                                  -18-

The LDGT2  emission  correction  factors  are based on the LDGV  information.
Therefore, the LDGT2 correction factors are those from the LDGVs,  and  the
discussions in Chapter 1 are valid for  the LDGT2s.

3.D.I  Speed Correction Factor

The test  procedure  used  for collecting the basic  exhaust emissions is  a
driving cycle with  an average  speed of 19.6  mph.   For those   situations
where  the  average  speed of the  truck  deviates from this value,  a  speed
correction  factor  is  applied.   The LDGT2  average cycle speed  emission
correcion factor is given in Table 1.3.6.

3.D.2  Emission Temperature Correction  Factor

The  established  LDGT2  emissions  test   procedure  requires   an   ambient
temperature  between  68 F   and  86F.   For  those  situations  where  the
ambient  temperature  is  not  in  this range,   an  emission   temperature
correction  factor   is  applied.   Table 1.3.7A  presents  this  correction
factor for the LDGT2s.

3.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A single  emission  correction  factor called Ripstwxn adjusts for  speed,
temperature,  and  operating-mode  conditions  that differ  from  the  basic
test  procedure.    As  described   in   Chapter  1,   Ripstwxn  depends   on
normalized bag  fractions.   The LDGT2 normalized bag  fractions are  given
in Table 1.3.7B.

3.D.4  Air Conditioning Correction Factor

The LDGT2 emissions  can be significantly affected  by   the  use  of  air
conditioning.  These  correction  factors  are given in Table  1.3.8A.   The
fractions of LDGT2s equipped with  an air  conditioner,  by model year,  are
given in Table 1.3.8A.

3.D.5  Extra Load Correction Factor

The basic exhaust emission  rates  are based on the "typical"  truck weight
with  a  driver and  passenger,  fuel,  and  other  liquids.    There are,
however,   situations in which trucks have  extra  weight  due to  additional
passengers, luggage, load,  etc.   In these events,  emissions are  known to
change.

To apply the truck extra load correction factor found in  Table  1.3.9 to  a
specific situation,  it is necessary for a user to have an estimate  of  the
percentage of LDGT2 VMT accumulated with an additional 500 pounds.

3.D.6   Trailer Towing Correction Factor

As with  the  extra  load  correction  factor,  the trailer towing  correction
factor will adjust LDGT2 emissions  for usage conditions which differ from
the basic  test procedure.  The  correction factor coefficients given  in
Table 1.3.10 are valid for a trailer weight of 1000 pounds.

3.D.7  NO* Humidity Correction Factor

The NOx emission  factors  are  normalized to 75 grains  of  water per pound
of  dry air.   la order  to adjust  NOx  emissions  to  different humidity
conditions, a multiplicative correction factor is available.  The formula
for the correction factor is given below, and is applicable for all model
years:

    HCF -   1.0 - .0047 * (H - 75)

where:

    HCF -   The NOx humidity correction factor.

                  HEAVY DUTY GASOLINE POWERED VEHICLES

4.A  INTRODUCTION

This chapter  presents the emission  factors  for the  heavy duty gasoline
powered vehicles  (HDGV).   A HDGV  is defined  to  be  any  gasoline fueled
motor vehicle designated primarily for the transportation of property and
rated at more than 8,500 pounds gross vehicle weight  (GVW), or designated
primarily  for transportation of  persons  and  having  a capacity  of more
than 12 persons.

This chapter  presents the  HDGV  emission factors in three major sections:
(1) Emissions,   (2) travel   weighting   fractions,   and   (3) emission
correction factors.

4.A.I  Test Procedure

The method  for  determining the HDGV emission  levels  is based on a test
procedure that is different  from  the procedures used in earlier editions
of AP-A2.  The HDGV basic  exhaust  emission rates  are  based on the engine
dynamometer transient test procedure stipulated in  the Federal Register
(45 FR  4181,  January 21,  1980) and  the Code  of  Federal  Regulations  (40
CRF, Part 86, Subpart N, July  1,  1980).   The basic test conditions under
which the HDGVs  are  tested are  as  follows:

    1.   Anbient  temperature range  is  688F  through 86F.
    2.   Absolute humidity is adjusted to  75  grains of water per pound  of
        dry air.
    3.   Estimated cycle  speed is 19.9 mph  with  27%  idle  operation.
    4.   Average  percent  VMT in  a cold start operation  is 14.3%.
    5.   Average  percent  VMT in  a hot  start operation is  86.7%.
    6.   No average percent VMT  in  the stabilized operation.
    7.   Estimated trip length is 6.5  miles.

The  test  procedure  for  the  HDGVs  can  be  briefly  described   by   the
following:

    1.   Generate the maximum torque vs.  speed curve of the  engine.
    2.   Precondition the engine with  practice cycle runs.
    3.   With  the  engine off, let  it sit for  at  least 12  hours  between
        68F  and  86F.   An  optional procedure  is the  forced cool-down
        procedure, whereby cool water  is  circulated (and/or air directed
        onto  the engine)  through  the engine's  water coolant system until
        the engine oil is between  68F  and 75F.
    4.   Conduct  the cold start  test.   The estimated mileage is 6.5 miles
        and cycle speed  is 19.9 mph.
    5.   Turn off the engine.
    6.   Keep the engine  off for 20 minutes.
    7.   Conduct  the hot  start  test.   The cycle is the same  as  the cold
        start cycle.
    8.   Calculate the grams  of-pollutant  and total brake  horsepower-hour
        for each test cycle.

                                  -21-
    9.  Correct NOx to 75 grains  of water per pound of dry air.
    10. Calculate  the  basic  exhaust  emissions  in   grams  per  brake
        horsepower-hour.

4.A.2  General Emissions  Calculation Equations

To calculate the HDGV  emissions,  the  following generalized equations are
used:

    (a) BEFnpst - SUMi(BERipn *  [NMi]  *  TFin *  SCFips *  TCFipt + CCEVi *
                         TFin)

    (b) lEFnp -   SUMi(IERipn *  [NMi]  *  TFin)

where the lower case letters  are  subscripts, the  [  ]'s  refer to optional
variables and:

    BEFnpst -   The basic exhaust emission factors  in grams per  mile on
                January 1  of calendar  year  n  for  pollutant  p,  average
                speed s,  and ambient  temperature t.

                                  -22-

levels, and (4)  idle exhaust  emission rates.   The emission standards are
given  in  Section A.1.3  of  Appendix  A.   The  emissions  reflect vehicles
which  have  received typical  in-use  maintenance.  Further,  the vehicles
are not involved in an  I/M program.

The discussions in Chapter 1  for  the  four emission subsections are valid
for  the  HDGVs.   Therefore,  the  discussions  will   not   be   reiterated.
Please refer to Chapter 1 for a complete discussion at the following four
subsections.

A.B.I  Basic Exhaust Emission Rates

The HDGV  basic  exhaust emission rates are  given in  Table 1.4.1A.  This
table  presents  the   HDGV   zero  mile  emission  levels   and  emission
deterioration rates for every model year.   From the  HDGV  test  procedure,
emissions are measured in grams  per  brake horsepower-hour.  However, the
emissions in  this  section are given  in  grams per mile  to be  consistent
with other emission measurements.

4.B.2  Crankcase and Evaporative  HC Emission Levels

The HDGV crankcase and evaporative HC emission levels are  given in Table
1.4.IB.   This table presents the  emissions  for every  model  year and
emission component:  diurnal  losses, hot soak losses, and crankcase  losses.

4.B.3  January 1 Basic  Exhaust Emission Levels

The January 1, 1970 through  1993, HDGV basic  exhaust  emission  levels are
given in Tables 1.4.2A through 1.4.2C for HC, CO, and NOx, respectively.
The  HC basic  exhaust  emission  levels reflect  total,  rather  than non-
methane, HC emissions  and exclude crankcase  and  evaporative  HC emission
levels.

4.B.4  Idle Exhaust Emission Rates (Hot Stabilized)

The HDGV  hot  stabilized  idle exhaust emission  rates  are  given in  Table
1.4.3.  These emissions  are measured in grams  per  minute  and  reflect
engines operating in a  hot stabilized  condition.

4.C  TRAVEL WEIGHTING FRACTIONS
The  HDGV  travel  weighting  fractions  are   the   individual model  year
proportions of the total HDGV VKT.  To generate the HDGV travel weighting
fractions, two distributions  are  required: (1) the  fleet  annual mileage
accumulation  rate distribution  and  (2)  the  registration  distribution.
These  two  distributions  are  given  in  Table  1.4.4.   More   detailed
information is available in Chapter 1 on these distributions.

The  travel weighting  fractions  in  this  document  reflect  a  January 1
evaluation date.   For the HDGVs,  the model  years  are assumed  to begin
sales on  January 1.   Further, it  is assumed that the  vehicles  are sold
and  accumulate  mileage  according  to  a  uniform  distribution.   These
assumptions  permit  the   estimation  of   the  January 1  fleet  mileage
accumulation   rate   distribution   and   the   January 1    registration

distrlbution from July 1 information.  The travel weighting fractions are
given in Table 1.1.5.

4.D  EMISSION CORSECTION FACTORS

The HDGV  basic  exhaust emission levels  are  based on  test results under
the standardized conditions defined in Section 4.A.I.  However, the basic
exhaust .emission  levels  are  affected   by   ambient   and   vehicle  usage
conditions  which  differ  from the  prescribed  test  procedure.   The
conditions under which HDGV  emissions  are known to  vary are the average
speed and ambient- temperature.  Emission correction factors are available
to compensate for these conditions.

4.D.I  Speed Correction Factor

The test  procedure used  for  collecting the basic  exhaust  emissions is a
transient engine cycle  with  an estimated  speed  of about  20.0 mph.  For
those   situations  where the   average  speed of the  vehicle deviates  from
this  value,  a   speed correction  factor  is  applied.   The  HDGV  speed
correction factor equations are as  follows:

    (a) SCFips - EXP(Aip + Bip*s +  Cip*s2) for HC and CO, and

    (b) SCFips - Aip + Bip*s  for NOx

where

    SCFips -    The correction  factor for model year i and  pollutant  p  at
                the average speed of s.

    EXP -       The exponential function.

    Aip        The  speed correction  factor  intercept  coefficient  for
                model year i  and pollutant p.

    Bip =       The speed  correction factor  first  order coefficient for
                model year i  and pollutant p.

    Cip -       The speed  correction factor  second order  coefficient for
                model year i  and pollutant p.

The coefficients  for  the  speed correction factor  equations are  given  in
Table 1.4.6.  The  speed  correction factors are  only  valid for speeds  in
the 5 through 55 mph range.

4.D.2  Emission Temperature Correction Factor

The  established  HDGV  test   procedure  requires  an  ambient  temperature
between 68F  and 86F.  For  situations  where the ambient  temperature  is
not in  this range,  an emission temperature correction factor  is  applied.
This  temperature correction  factor differs  slightly  in  form   from  the
temperature correction  factor given in  Chapter  1.   The HDGV  temperature
correction factor is  for the  entire  transient  test as  opposed  to  the  LDGV
temperature  correction factors  for the  individual  test   segments.   The

-------
                                  -24-

HDGV  temperature correction  factor  is  given  in   Table  1.4.7  and  the
equation is as follows:

    TCFipt -    EXP(TCiptt(T - TT))

where the lower case letters are subscripts and

    TCFipt =    The emission temperature correction factor for model year
                i, pollutant p, and  ambient temperature  t.

    EXP **       The exponential function.

    TCiptt     The  temperature  correction factor  coefficient  for  model
                year 1, pollutant p, and reference temperature  tt.

    T -         Ambient temperature  (Fahrenheit).

    TT -        Reference temperature which equals  67.5F  when T is less
                than 680F and equals 86.5F when T is greater than 86F.

                   LIGHT DUTY DIESEL POWERED VEHICLES

5. A  INTRODUCTION

Diesel powered  passenger  cars are  becoming more prominent  in the light
duty vehicle fleet*  As a result, emission factors are required for these
light duty diesel  powered vehicles  (LDDV).   A LDDV is defined to be any
diesel fueled  motor vehicle  designated primarily for  transportation of
persons and having a capacity of 12  persons  or fewer.

As with  the  other chapters,  the  LDDV emission factors  are  presented in
three major  sections:  (1) Emissions,  (2)  travel weighting fractions, and
(3) emission correction factors.

5.A.I  Test Procedure

The test procedure used for determining the LDDV basic exhaust emissions
is identical to  the  LDGV  test procedure.  Therefore, refer  to Chapter 1
for a brief overview.

5.A.2  General Emissions Calculation Equations

The  LDDV  generalized  equations   are  almost  identical  to  the  LDGV
equations.    The  differences  are  the four  optional  emission correction
factors and the crankcase and evaporative HC  emissions.  To  calculate the
LDDV emissions, the following generalized  equations are used:

    (a) BEFnpstwx - SUMi(BERipn * [NMi]  *  TFin * Ripstwxn)

    (b) lEFnp =     SUMi(IERipn * [NMi]  *  TFin)

where the lower case letters  are  subscripts,  the  [  ]'s refer  to  optional
variables and:

    BEFnpstwx - The  basic  exhaust   emission  factors in grams/mile  on
                January 1 of  calendar year  n, pollutant  p, average  speed
                s, ambient  temperature  t, VMT fraction of  vehicles in a
                cold start mode w,  and  VMT  fraction  of  vehicles in a hot
                start mode x.

    SUMi( ) -   The  summation over  20  model  years  from i=n-19  to  i=n,
                where n is the calendar  year.

    BERipn >    The basic exhaust emission  level  in  grams/mile for model
                year 1  and pollutant p on  January 1 of calendar year n.

    NMI        The non-methane  fraction  of  total HC for model  year i.
                This  optional  variable  can  only   be   applied   to  HC
                emissions and is defined in  Section E  of  the  INTRODUCTION.

    TFin       The model year  i  fraction of the total LDDV miles  driven
                on January 1 of calendar year n.

-------
                                  -26-
    Ripstwxn =  The  speed/temperature/operating-mode  correction  factor
                for model year i,  pollutant  p, average  speed  s, ambient
                temperature  t, VMT  fraction  in a  cold start  w,  and VHT
                fraction of vehicles  in  a hot start  x;  on  January  1 of
                calendar year  n.

    lEFnp =     The  idle exhaust  emission  factors  in  grams/minute  on
                January 1 of calendar  year n  for pollutant p.

    XERipn     The  idle exhaust  emission  levels  in grams/minute  for
                model year  i  and pollutant  p on  January 1  of calendar
                year n.

5.B EMISSIONS
This  section  discusses  the  LDDV  emission  estimates:  Basic  exhaust
emission rates,  crankcase  and evaporative HC  emission levels, January 1
basic exhaust  emission  levels,  and  idle exhaust  emission  rates.    The
emission  standards  are given  in  Section  A.1.1  of  Appendix A.    The
emissions   reflect  vehicles   which   have    received   typical   in-use
maintenance.  Further,  the  vehicles  are  not involved in an I/M  program.

With  the  exception of  the crankcase and evaporative  HC emissions,  the
discussions of  the different  emissions  in Chapter  1  are  also valid  for
the LODVs.   Therefore,  the discussions will  not be  reiterated.   Please
refer to Chapter 1 for  the discussions that correspond  to  the  subsections
below.

5.B.I  Basic Exhaust Emission Rates

The LDDV  basic exhaust  emission  rates  are given in  Table  1.5.1.   This
table  presents  the   LDDV  zero  mile   emission   levels  and  emission
deterioration rates for  every model year. The emissions are measured in
grams per mile.

5.B.2  Crankcase and Evaporative HC  Emission Levels

LDDVs are  considered  to have insignificant crankcase  and evaporative HC
emission levels.  Therefore,  no emission estimates are  given.

5.B.3  January 1 Basic Exhaust Emission  Levels

January  1,  1970 through 1993,  LDDV basic  exhaust  emission  levels  are
given in Tables  1.5.2A  through 1.5.2C for HC,  CO, and  NOx,  respectively.
The HC  basic  exhaust  emission  levels  reflect  total, rather  than non-
methane, HC emissions.

5.B.4  Idle Exhaust Emission Rates (Hot  Stabilized)

The LDDV  hot  stabilized idle exhaust emission rates  are  given in  Table
1.5.3.   These  emission levels  are  measured  in  grams  per  minute  and
reflect engines operating in a hot stabilized condition.

                                  -27-

5.C  TRAVEL WEIGHTING FRACTIONS

The LDDV travel weighting fractions are individual model year proportions
of the total LDDV VMT.  To generate the travel weighting fractions, three
distributions are  required: '(1)  the  fleet  annual  mileage  accumulation
rate  distribution,  (2)  the   registration  distribution,   and  (3)  the
estimated  fleet   sales   fraction  distribution  (to   account   for  the
proportional increase of diesel powered vehicles).   The first  and second
distributions are  given in Table  1.5.4A,  and the  third  distribution is
given in Table 1.5.4B.  More detailed information is available in Chapter
1 on these distributions.

The  travel  weighting   fraction  in  this  document   reflect  a  January 1
evaluation date.   For the LDDVs,  the model year is assumed to begin sales
on the October 1 preceding the corresponding  calendar  year.   Further, it
is assumed that the vehicles are sold and accumulate mileage according to
a uniform  distribution.   These  assumptions permit the  estimation  of the
January 1 fleet mileage accumulation  rate  distribution and the January 1
registration distribution  from July  1 information.   An  example  of  the
travel weighting fraction calculation is given in Table 1.5.5.

5.D  EMISSION CORRECTION FACTORS

The LDDV  basic  exhaust  emission levels are  based on  test results under
the standardized  conditions  defined  in  Chapter  1.    However,  the basic
exhaust  emission  levels  are  affected   by   ambient  and  vehicle  usage
conditions  which  differ  from   the   prescribed  test  procedure.   The
conditions under which LDDV emissions are known to  vary  are the average
speed, ambient  temperature, and fraction  of  VMT in cold and  hot start
operating modes.  Emission correction factors are available to compensate
for these conditions.  Use  of air conditioning,  carrying  of  an extra
load,  trailer towing, and  humidity levels may affect LDDV emissions, but
no information is available to  estimate the effects.

5.D.I  Speed Correction Factor

The test  procedure used for  collecting the basic exhaust  emissions is a
driving cycle with an average  speed of 19.6  mph.   For those  situations
where  the average speed of the vehicle deviates  from this value, a speed
correction  factor  is  applied.    This correction   factor will  now be
examined  and  later incorporated  into  the Rlpstwxn  correction  factor in
Section 5.D.3.

The LDDV  speed  correction factor is  based  on the  heavy  duty   diesel
vehicle  (HDDV) correction  factor,  and is  fully  defined in Section 7.D.I
of Chapter  7.   The  speed  correction factor  for LDDVs  is normalized to
19.6. mph.  The LDDV speed correction factor equation is as  follows:

   SCFipswx - EXP(Aip + Bip*s + Cip*s2)/EXP(Aip + Bip*sadj  +  Cip*sadj2)

where  the lower case letters are  subscripts and

    SCFipswx   The  speed  correction  factor  for model year i,  pollutant
                p, and  average  speed s,  normalized  for the  cold start w
                and hot  start x VMT fractions.

-------
                                  -28-
    EXP =       The exponential function.

    Aip =       The  speed correction  factor  intercept  coefficient  for
                model year i  and pollutant, p.

    Bip =       The  speed  correction factor first  order coefficient  for
                model year i  and pollutant p*

    Cip =       The  speed  correction factor second order coefficient  for
                model year i  and pollutant p.

    sadj =      The adjusted  speed, adjusted for the cold start w and  hot
                start x VMT fractions.   I/ sadj  = ((w + x)/26) + 1  -  w  -
The user is cautioned that  the  correction factor as given in Table  1.5.6
is  only valid  for  speeds in  the  5  through  55  mph  range  since  the
regression  equations   were  based   on   speed   data  in   that   range.
Extrapolations to speeds beyond  this range should not  be made.

5.D.2  Emission Temperature Correction Factor

The  established  LODV  emissions  test  procedure  requires  an   ambient
temperature between 68F  and  86F.   For  those  situations  where  the
ambient  temperature  is  not  in  this  range,  an  emission temperature
correction  factor is  applied.    Table  1.5.7A presents  this  correction
factor for the LDDVs.   Based  upon the coefficients  given in Table  1.5.7A
(which  are   all  zero),   LDDV   emissions  will  not   be   affected   by
temperature.   Based on  engineering   judgement  and  limited data,   LODV
emissions appear to be  insensitive to temperature.

5.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A  single  emission correction factor  called Ripstwxn adjusts  for  speed,
temperature,  and  operating-mode  conditions that differ  from  the  basic
test  procedure.   As   described   in  Chapter  1,  Ripstwxn  depends   on
normalized bag fractions.  The LDDV normalized bag fractions are  given in
Table 1.5.7B.

                    LIGHT DUTY DIESEL POWERED TRUCKS

6.A  INTRODUCTION

The light  duty  diesel powered trucks (LDDT)  are  becoming  more prominent
in the light duty truck  fleet.  Therefore,  the  LDDT emission factors are
required.   A LDDT  is defined  to  be any  diesel  fueled  motor  vehicle
designed  primarily  for  transportation  of  property and  rated at  8,500
pounds tro vehicle weight  or less.

This chapter,  like  all  others, divides  the emission  factors  into three
major  sections:  (1) Emissions, (2)  travel  weighting  fractions,  and (3)
emission correction factors.

6.A.I  Test Procedure

The test  procedure  used  for  determining  the LDDT basic exhaust emissions
is almost  identical to the LDGV  test procedure.   The difference between
the two  test procedures is  primarily the  road-load  horsepower  setting.
The summary of  the test procedure  in  Chapter 1  is  correct  for LDDTs.
Therefore, refer to Chapter 1 for  a brief  overview.

6.A.2  General Emissions Calculation Equations

The generalized calculating  equations  for  the LDDTS are  presented in
Chapter  5..  All of  the  equations  are identical,  although the  emissions,
travel weighting fractions,  and  emission correction  factors  levels for
LDDTs are different from the LDDVs.

6.B  EMISSIONS
This  section  discusses  the  LDDT  emission  estimates:  Basic   exhaust
emission rates,  crankcase  and evaporative HC emission  levels,  January  1
basic exhaust  emission  levels,  and  idle exhaust  emission  rates.    The
emission standards  are  given in Section  A.1.2  of Appendix  A.   Prior  to
the  1978  model year, the  number of LDDTs  are  considered insignificant.
As  a result, no  emissions  are measured  prior  to January 1,  1978.    The
emissions  also   reflect   trucks  which   have  received  typical  in-use
maintenance.  Further, the  trucks are not  involved in  an I/M  program.

With  the  xcption of  the crankcase  and evaporative  HC emissions,  the
discussions  of  the different  emissions  in Chapter 1 are valid  for  the
LDDTs.  Therefore,  the  discussions  of  the different emissions in  Chapter
1 will not be reiterated.   Please refer  to Chapter  1 for the discussions
that correspond to the subsections  below.

6.B.1  Basic Exhaust Emission Rates

Th*  LDDT  basic exhaust  emission rates are  given in Table  1.6.1.   This
table  presents   the  LDDT  zero  mile   emission  levels  and  emission
deterioration rates for  every model year.  The  emissions are measured in
grams per mile.

                                  -30-
6.B.2  Crankcase and Evaporative HC Emission Levels

LDDT are  considered to have  insignificant  crankcase and  evaporative HC
emission levels.  Therefore,  no emission estimates are given.

6.B.3  January 1 Basic Exhaust Emission Levels

January  1,  1978  through  1993,  LDDT  basic exhaust  emission  levels are
given in Tables 1.6.2A through 1.6.2C for HC,  CO,  and NOx, respectively.
The  HC  basic  exhaust  emission  levels  reflect   total,   rather   than
non-methane,  HC emissions.

6.B.4  Idle Exhaust Emission  Rates (Hot Stabilized)

The LDDT hot  stabilized  idle exhaust emission  rates are given  in Table
1.6.3.   These  emission  levels  are  measured  in  grams  per   minute and
reflect engines operating in  a hot stabilized condition.

6.C  TRAVEL WEIGHTING FRACTIONS

The  LDDT  travel  weighting   fractions  are  the  individual   model   year
proportion of  the  total  LDDT  VMT.  To  generate  the" travel weighting
fractions,  three distributions are  required:  (1) the fleet annual mileage
accumulation  rate  distribution,  (2)  the  registration  distribution, and
(3) the  estimated  fleet  sales fraction distribution  (to  account  for the
proportional  increase  of  diesel  powered trucks).   The first  and second
distributions are  given  in Table 1.6.4A,  and the  third  distribution is
given in Table  1.6.4B.  More detailed information is available in Chapter
1 on these distributions.

The  travel weighting  fractions  in  this  document  reflect a January  1
evaluation date.  For the  LDDTs,  the model  year is assumed to  begin  sales
on the October  1 preceding the corresponding  calendar year.  Further, it
is assumed that the trucks  are sold  and accumulate mileage according  to  a
uniform  distribution.   These assumptions  permit the  estimation  of the
January 1 fleet mileage accumulation rate distribution  and  the January  1
registration  distribution  from  July 1  information.   An  example  of the
travel weighting fraction calculation is given in Table  1.6.5.

6.D  EMISSION CORRECTION FACTORS

The LDDT  basic  exhaust emission levels are  based on  test  results  under
the standardized  conditions  defined in  Chapter  1.   However,  the  basic
exhaust  emission   levels  are  affected  by   ambient  and  truck   usage
conditions  which   differ  from  the  prescribed  test  procedure.   The
conditions under which LDDT  emissions are  known to  vary  are   the average
speed, ambient  temperature,  and fraction of  VMT in cold  and hot  start
operating modes.  Emission correction factors are available to compensate
for  these  conditions.  Use  of air conditioning,  carrying of  an  extra
load, trailer towing,  and humidity  levels may affect LDDT emissions, but
no information is available  to estimate  the effects.

                                  -31-

6.D.I  Speed Correction Factor

The test procedure used  for  collecting the basic  exhaust  emissions is a
driving cycle with an  average speed of 19.6 mph.   For those  situations
where  the  average  speed of the truck  deviates from this  value,  a speed
correction  factor  is  applied.    This correction factor will  now  be
examined and  later incorporated into  the  Ripstwxn correction  factor in
Section 6.D.3.

The LDDT emission  cycle  speed correction  factor given  in  Table 1.6.6 is
based  on the  heavy duty diesel vehicle  (KDDV) correction  factor  and Is
fully  defined in Section 7.D.I  of Chapter 7.   The LDDT speed correction
factor  is  normalized  to 19.6   and  is   identical  to the  LDDV  speed
correction factor.

The  user  is  cautioned  that  this correction  factor  is  only  valid   for
speeds in the 5 through  55 mph  range since the regression equations were
based  on speed data in that  range.   Extrapolations to speeds beyond this
range  should not be made.

6.D.2  Emission Temperature Correction Factor

The  established  LDDT   emissions  test  procedure  requires  an  ambient
temperature  between  68F  and  86F.   For  those  situations  where   the
ambient  temperature  is  not  in   this range, an emission  temperature
correction  factor  is  applied.    Table 1.6.7A presents  this  correction
factor for  the  LDDTs.   Based on  the coefficients given  in Table  1.6.7A
(which  are   all   zero),  LDDT   emissions  will  not   be  affected  by
temperature.  Based  on  engineering  judgement  and limited  data,   diesel
emissions appear to be insensitive to temperature.

6.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A  single  emission correction factor called  Ripstwxn  adjusts for  speed,
temperature,  and  operating-mode  conditions  that  differ   from  the basic
test   procedure.   As   described   in  Chapter   1,  Ripstwxn  . depends  on
normalized bag fractions.  The LDDT  normalized  bag fractions  are given in
Table  1.6.7B.

                   HEAVY DUTY DIESEL POWERED VEHICLES

7.A  INTRODUCTION

This  chapter  presents  the  emission  factors for  the heavy  duty diesel
powered vehicles (HDDV).  A HDDV is defined to be any diesel  fueled motor
vehicle designated primarily for the transportation of property and rated
at more  than  8,500 pounds of  gross vehicle weight  (GVW),  or designated
primarily  for  transportation of  persons  and having  a  capacity  of more
than 12 persons.

This chapter presents the HDDV  emission factors in three major sections:
(1) Emissions,    (2) travel   weighting   fractions,   and    (3)  emission
correction factors.

7.A.I  Test Procedure

The test procedure used  for  determining the HDDV basic  exhaust emissions
is almost  identical to  the  HDGV  test procedure.  The  major difference
between  the  two  test  procedures  is   the  test  cycle.   The HDDV  test
procedure is similar to  the one for HDGVs.  Therefore, refer  to Chapter 4
for a brief overview. The specific differences  are as follows:

    1.  The HDDV  test  procedure estimated  cycle  speed  is  19.2  mph with
        37% idle operation.
    2.  The HDDV  test  procedure  has  the estimated  trip length of   6.4
        miles.
    3.  NOx is not corrected  for humidity.

7.A.2  General Emissions Calculation Equations

To calculate the HDDV emissions,  the following  generalized  equations  are
used:

    (a) BEFnpst = SUMi(BERipn *  [NMi]  * TFin "* SCFips  * TCFipt)

    (b) lEFnp =   SUMi(IERipn *  [NMi]  * TFin)

where the lower case letters are  subscripts, the  [  ]'s refer to  optional
variables and:

    BEFnpst    The basic exhaust  emission  factors  in grams  per  mile on
                January  1  of calendar  year n  for  pollutant  p,  average
                speed s,  and  ambient temperature t.

    SUMi( ) =   The  summation over 20  model years  from i=n-19  to i=n,
                where n  is the calendar year.

    BERipn -    The basic exhaust emission  level  in  grams/mile for model
                year i and pollutant p  on  January  1 of calendar year n.

-------
                                  -33-

    NMi        The  non-methane fraction of  total HC  for model  year  i.
                This  optional  variable  can  only  be   applied   to  HC
                emissions and  is defined in Section E of the INTRODUCTION.

    TFin -      The  model  year i fraction of  the  total HDDV miles driven
                on January  1 of calendar year  n.

    SCFips -    The   speed   correction  factor  for  model   year   i  and
                pollutant p at the average speed of s.

    TCFipt -    The  temperature correction  factor for  model year  i and
                pollutant p at the ambient temperature of t.

    lEFnp      The  idle  exhaust  emission  factors  in grams/minute  on
                January 1 of calendar  year n  for pollutant p.

    lERlpn     The  idle exhaust  emission level in grams/minute for model
                year i and  pollutant p on January  1 of calendar year n.

7.B EMISSIONS

This  section  discusses the emission  estimates for the HDDVs.   The four
subsections are (1)  basic exhaust   emission rates,  (2)  crankcase and
evaporative HC  emission  levels,  (3) January 1  basic exhaust   emission
levels, and (4) idle  exhaust  emission rates.  The emission standards are
given  in Section A.1.4 of Appendix  A.   The  emissions  reflect  vehicles
which  have received typical  in-use  maintenance.   Further,  the  vehicles
are not involved in  an I/M  program.

With  the exception  of  the crankcase and  evaporative HC  emissions, the
discussions in Chapter 1 for  the  four emission subsections are valid for
the  HDDVs.   Therefore,  the  discussions  will not  be reiterated  here.
Please  refer  to Chapter  1 for  the   discussions  that  correspond  to the
subsections below.

7.B.I  Basic Exhaust Emission  Rates

The HDDV  basic  exhaust emission rates  are  given in  Table 1.7.1A.  This
table   presents   the   HDDV  zero  mile  emission  levels  and   emission
deterioration rates for every model  year.   From the HDDV test  procedure,
emissions  are measured  in  grams  per  brake horsepower-hour.  However, the
emissions  in this section are  given in grams  per mile  for  consistency.

7.B.2  Crankcase and Evaporative  HC  Emission  Levels

HDDVs  are  considered  to have insignificant  crankcase  and evaporative HC
emission levels.  Therefore,  no emission estimates are  given.

7.B.3  January 1 Basic Exhaust Emission Levels

The January 1,  1970 through 1993,  HDDV basic exhaust emission levels are
given  in Tables 1.7.2A through  1.7.2C for HC, CO, and NOx,  respectively.
The  HC  basic  exhaust emission  levels   reflect  total,  rather  than
non-methane, HC emissions.

-------
                                  -34-
7.B.4  Idle Exhaust Emission Rates  (Hot  Stabilized)

The HDDV hot  stabilized  idle exhaust emission rates are  given in  Table
1.7.3.   These emissions are measured  in grams  per minute  and reflect
engines operating in a hot  stabilized condition.

7.C  TRAVEL WEIGHTING FRACTIONS

The  HDDV  travel  weighting  fractions   are   the  individual   model  year
proportions of the total HDDV VMT.   To generate the HDDV  travel weighting
fractions,  two distributions are  required:  (1) the  fleet annual mileage
accumulation  rate distribution  and  (2)  the  registration distribution.
These  two  distributions  are  given  in  Table  1.7.4.   More  detailed
information is available in Chapter 1 on these distributions.

The  travel weighting  fractions in  this  document  reflect  a January 1
evaluation date.   For the  HDDVs,  the model  years  are assumed  to begin
sales on January 1.   Further, it  is assumed  that the  vehicles  are sold
and  accumulate  mileage according  to   a uniform   distribution.   These
assumptions  permit  the  estimation of  the  January 1  fleet  mileage
accumulation   rate   distribution    and   the   January  1    registration
distribution from July 1 information.   The travel weighting  fraction are
given in Table 1.7.5.

7.D  EMISSION CORRECTION FACTORS

The HDDV basic  exhaust emission levels  are  based on  test results under
the  standardized conditions defined  in Section  4.A.I  of  Chapter  4 and
Section 7.A.I.   However, the basic  exhaust emission levels are affected
by ambient and vehicle  usage conditions which differ from  the prescribed
test procedure.   The  conditions under which  HDDV emissions are  known to
vary are the  average  speed  and ambient  temperature.   Emission correction
factors are available to compensate for  these  conditions.

7.D.I  Speed Correction Factor

The test procedure used  for collecting  the basic exhaust emissions is a
transient engine  cycle with an estimated speed of  about 20.0 mph.  For
those  situations  where  the average speed  of the vehicle deviates from
this  value,   a  speed correction  factor  Is  applied.    The   HDDV  speed
correction factor equation  is as follows:

    SCFips = EXP(Aip + Bip*s + Cip*s2)

where

    SCFips =    The correction factor for model year 1 and  pollutant p at
                the average speed of s.

    EXP =       The exponential function.

    Alp =       The  speed   correction factor  intercept  coefficient  for
                model year  i and pollutant p.

-------
                                  -35-
    Bip -       The speed correction  factor first order  coefficient for
                model  year 1 and pollutant p.

    Cip        The speed correction  factor  second  order coefficient for
                model  year i and pollutant p.

The coefficients for  the  speed correction factor equations  are given in
Table 1.7.6.  The  speed correction  factors  are only  valid  for speeds in
the 5  through  55 mph range.   Further,  the speed correction factors are
normalized to 20.0 mph.

7.D.2  Emission Temperature  Correction Factor

The established  HDDV  emissions test  procedure requires an  ambient  test
temperature between 68F and 86F.  For situations which differ from  this
ambient temperature range,  an emission temperature  correction factor is
applied.   This  temperature  correction  factor  differs  slightly from the
temperature correction factor  given in Chapter 1.   The HDDV  temperature
correction factor is for the entire transient test as opposed to the  LDGV
temperature  correction  factors for  the individual  test  segments.   The
HDDV  temperature  correction  factor  is  given  in  Table  1.7.7 and the
equation is as follows:

    TCFipt -    EXP(TCiptt(T - TT))

where the lower case letters are subscripts  and

    TCFipt     The emission temperature correction factor for model  year
                i,  pollutant p, and  ambient  temperature  t.

    EXP -       The exponential function.

    TCiptt -    The temperature correction  factor coefficient  for model
                year i,  pollutant  p,  and reference temperature  tt.

    T <>         Ambient  temperature  (Fahrenheit).

    TT         Reference  temperature which equals 67.5F when T is  less
                than 68F and equals 86.5F  when T is  greater than 86F.

All of the coefficients  in Table 1.7.7 are zero.  This  indicates that the
HDDV emissions are not affected by temperature.

                               MOTORCYCLES

8.A  INTRODUCTION

Motorcycles  usually  are  not  considered  a  significant  source  of  air
pollution.   However,   they  are  becoming  a  dominant  fleet.    In 1978,
approximately 7.3 million motorcycles (MC)  were  registered in the United
States.  With  the  exception of light duty  gasoline  powered vehicles and
trucks  (less than  6,001  pounds gross  vehicle weight),  motorcycles are
more abundant than other vehicle types.

A motorcycle is defined as  any  motor  vehicle  designed to travel with not
more  than  three wheels in  contact  with the  ground, and  weighting less
than 1,500 pounds.

The MC fleet  is  composed  of  six  engine size-type  combinations: small,
medium,  and  large   engine sizes,   each   size   having  two-stroke  and
four-stroke  engine  types.   Small   or  Class  I  motorcycles  have engine
displacements  in  the  50 cubic centimeter  (cc)  through  169  cc range..
Medium or  Class II  motorcycles have  engine displacements in  the 170 cc
through  279  cc range.   Large  or  Class  III motorcycles have engine
displacements in the 280 cc  and over range.

As with  other  chapters,  the MC  emission  factors are divided  into three
sections: Emissions,  travel weighting fractions,  and emission correction
factors.

8.A.I  Test Procedure

With  the  exception  of the  Class  I  motorcycles,  the  MC  basic  exhaust
emissions  test  procedure  is   identical  to   the  LDGV  test  procedure.
Therefore,  with  the  one  class exception,   the  summary  of   the  test
procedure in Chapter 1 is correct for the MCs.  Given below is a  list of
Class I motorcycle test procedure summary statistics that differ  from the
LDGV test procedure.

    1.  Average speed is 17.8 mph.
    2.  Average percent VMT  in  cold  start operation is 18.3%.
    3.  Average percent VMT  in  hoc start operation is  24.2%.
    4.  Average percent VMT  in  the stabilized  operation is 57.5%.
    5.  Average trip length  is  6.8 miles.
    6.  Test segment  #1 (cold   start) and  #3  (cold  start) each have an
        average trip length  of  2.89  miles and  speed of 20.6  mph.
    7.  Tc^t segment  //2 (stabilized) has the  average  trip length  of 3.91
        miles and speed of 16.2 mph.

8.A.2  General Emissions Calculation Equations

The MC generalized  equations are almost identical  to the LDGV equations.
The differences are  three optional emission  correction  factors  that are
not  applicable for  MCs:   air  conditioning,  extra load,  and  trailer
towing.  With these three exceptions, the MC  emission factors  calculating
equations are identical to the  LDGV  equations  given in Chapter  1.

8.B  EMISSIONS

This section discusses the MC  emission estimates:  Basic exhaust emission
rates,   crankcase  and evaporative  HC  emission levels,  January  1 basic
exhaust emission levels,  and  idle exhaust emission  rates.   The emission
standards  are given in  Section A.1.5  of  Appendix  A.   The  emissions
reflect  motorcycles  which have received   typical  in-use maintenance.
Further, the motorcycles  are not involved in  an I/M program.

With the  exception of the six  engine  size-type combinations being sales
weighted,  the  discussions of  the  different  emissions  in  Chapter 1 are
also  valid  for  the  MCs.   Therefore,  the  discussions  will   not   be
reiterated.   Please  refer  to  Chapter  1   for  the  discussions  that
correspond to the subsections below.   Further,  it  is assumed that the MC
emissions  reflect  exactly the  standard.zed  test conditions described  in
Chapter 1.

8.B.I  Basic Exhaust Emission  Rates

The  MC  basic exhaust emission rates  are  given  in  Table  1.8.1A.  This
table   presents   the  MC  zero  mile   emission  levels   and  emission
deterioration rates  for every model  year.   The emissions are measured  in
grans per mile.

8.B.2  Crankcase and Evaporative HC  Emission  Levels

The MC  crankcase  and evaporative HC emission levels are  given in Table
1.8.IB.   This table presents  the  emissions  for every  model  year and
emission component: diurnal losses,  hot soak  losses,  and crankcase  losses.

8.B.3  January 1 Basic Exhaust  Emission Levels

January 1, 1970 through  1993,  MC basic exhaust  emisson levels are given
in Table 1.8.2A through  1.8.2C for HC,  CO, and NOx,  respectively.  The  HC
basic exhaust emission levels reflect  total,  rather  than non-methane,  HC
emissions and exclude crankcase and  evaporati've HC  levels.

8.B.4  Idle Exhaust Emission Rates  (Hot Stabilized)

The  MC  hot stabilized idle  exhaust emission rates  are given  in Table
1.8.3.    These emissions  are  measured  in  grams  per minute  and  reflect
engines operating  in a hot stabilized condition.

8.C  TRAVEL WEIGHTING FRACTIONS

The  MC   travel  weighting  fractions   are   the  individual  model  year
proportions of  the total MC  VMT.   To  generate the MC travel weighting
fractions, two distributions  are required:  (1) the  fleet annual  mileage
accumulation  rate  distribution  and (2)  the  registration  distribution.
These  two  distributions  are  given  in  Table   1.8.4.    More   detailed
information is available  in Chapter  1 on these distributions.

-------
                                  -38-

The  travel weighting  fractions  in this  document  reflect  a  January 1
evaluation date.  For the MCs,  the  model year is  assumed  to begin sales
on January 1.  Further, it  is  assumed that the motorcycles  are sold and
accumulate  mileage   according   to  a   uniform   distribution.    These
assumptions  permit  the  estimation  of   the  January 1  fleet  mileage
accumulation   rate   distribution   and   the   January 1    registration
distribution from July 1 information.   The travel weighting fractions are
given in Table 1.8.5.

8.D  EMISSION CORRECTION FACTORS

The MC basic exhaust emission  levels  are  typically based on test results
under the  standardized  conditions  defined in  Chapter 1.   However,  the
basic  exhaust  emission  levels  are   affected   by  ambient  and  usage
conditions  which  differ  from   the   prescribed   test  procedure.    The
conditions under which emissions are known to vary are the average  speed,
anbient  temperature,  fraction  of  VMT  in  cold and hot  start  operating
conditions,  and   humidity   level.    Emission  correction   factors  are
available to compensate  for  these  varying conditions.

The MC emission correction factors  are  based  on the LDGV information and
the discussions in Chapter 1 are valid  for  MCs.

8.D.I  Speed Correction Factor

The  test  procedure used for collecting the  basic exhaust  emissions is
typically a driving cycle with an average  speed of 19.6 mph.  For  those
situations where the average speed  of  the  MC  deviates from this, value, a
speed correction  factor is  applied.   The  MC speed  emission  correction
factor is given in  Table 1.8.6.

8.D.2  Emission Temperature  Correction Factor

The established motorcycle  emissions  test procedure  requires an ambient
test temperature  between 68F and  86F.   For those situations  where the
ambient  temperature  is not  in   this  range,  an emission  .temperature
correction  factor is  applied.   Table  1.8.7A  presents this  correction
factor for the MCs.

8.D.3  Speed/Temperature/Operating-Mode Emission Correction Factor

A  single  emission correction  factor  called  Ripstwxn  adjusts for  speed,
temperature, and  operating-mode  conditions  that   differ  from  the  basic
test  procedure.   As   described  in   Chapter  1,   Ripstwxn  depends  on
normalized bag  fractions.   The MC  normalized bag  fractions  are given in
Table 1.8.7B.

8.D.A  NOx Humidity Correction Factor

The NOx emission  factors are normalized to 75 grains  of  water per pound
of  dry  air.   In order  to   adjust  NOx  emissions  to  different humidity
conditions, a multiplicative correction factor is available.  The foraula
for the correction factor is given  below, and is applicable for all model
years:

            CALIFORNIA HIGHWAY MOBILE  SOURCE EMISISON FACTORS

Compared  to  the rest  of the nation,  California highway  mobile sources
usually  have  different  emission  control'  regulations  in  effect    These
regulations  are given  in  Section  A.2  of  Appendix  A.   Although  the
emission  standards  are  usually different  for  these  California  vehicle
types, the  test procedure,  emission calculation  equations,  and emission
factor section and subsection discussions are identical to those given in
low  altitude  non-California chapters.   Therefore,  the  discussions will
not  be  repeated.   To alter the eight  preceding chapters  to  discuss the
California emission factors, two  basic changes  are  required:   (1) Change
the region prefix number in  all  tables from "1" to "2"  and (2) change the
reference Section A.l# to A.2# for Appendix A.

                               Chapter 10

                  HIGH ALTITUDE NON-CALIFORNIA HIGHWAY
                     MOBILE SOURCE EMISSION FACTORS

Compared  to  the  low  altitude non-California  region,  the  high  altitude
non-California   highway   mobile   sources   usually   have   no   specific
regulations.    Generally,  the  high  altitude  vehicle types  are  the  low
altitude  counterparts being  operated  at high  altitude.   There are a  few
exceptions which are given in Section  A.I of Appendix A.

The high  altitude non-California highway mobile  source emission factors
are different from those of  the  low altitude sources.  However,  with  one
exception, the discussions  in Chapters 1 through  8  can  be  used for  the
high  altitude emission  factors.   The one  exception  is to  change  the
region  prefix  number  in  all  tables  from  "1"  to  "3".    No  further
discussions  will be made  for the  high  altitude  non-California  highway
mobile source emission factors.

                               Appendix A

                     NEW VEHICLE EMISSION STANDARDS

This appendix  presents  the emission  standards  assumed  in this  document.
At  the  time of  the  MOBILE2 release,  these  were the  past,  present,  and
projected standards.  However,  it is possible that  some  of the  assumed
standards are now different due to changes in regulations,  waivers, etc.

A.I'  LOW  AND  HIGH  ALTITUDE  NON-CALIFORNIA  HIGHWAY  VEHICLE   EMISSION
STANDARDS
This section presents  the  emission standards for  the  eight low and  high
altitude  non-California  vehicle types.   The standards  are presented  in
five subsections.  The light duty vehicle and light  duty truck  fleets are
comprised of  both diesel  and  gasoline powered  vehicle  types.  Further,
the LDGT2 standards are  split among  the two  associated vehicle  types.
The pre-1979 model year LDGT2s are heavy duty vehicles  while the 1979 and
later  model years  are light  duty trucks.   Finally,   the  high altitude
standards  are  included  in  this  section  since  there  are  few emission
standards specific to the high altitude vehicle  types.

All hydrocarbon  emission  standards  in this  section   are  presented  for
total hydrocarbon emissions.

 LIGHT DUTY VEHICLES

 1   Standards do not apply to vehicles with engines less than 50 CID from 1968
     through 1974.

 2   Different test procedures have been used since the early years of emission
     control which vary in  stringency.   The appearance that the standards were
     relaxed from 1971 to  1972  is incorrect.  The  1972  standards are actually
     more  stringent  because of   the   greater   stringency  of  the  1972  test
     procedure.

 3   Applies only to diesels.

 4   Evaporative emissions determined by carbon  trap  method through 1977, SHED
     procedure beginning  in 1978.   Applies  only to gasoline-fueled vehicles.

 5  'Evaporative standard does not apply to off-road utility vehicles for  1971.

 6   Cars  sold  in specified high altitude  counties required  to meet standards
     at high altitude.

 7   Carbon monoxide  standard can be waived to  7.0 gpm for 1981-82  by  the EPA
     Administrator.

 8   Oxides  of nitrogen  standard can  be  waived   to 1.5  gpm  for innovative
     technology or diesel.

 9   Oxides of  nitrogen  standard  can be waived  to  2.0 gpm  for American  Motors
     Corporation.

 10  Standards in parentheses apply to vehicles sold  in specified high altitude
     counties.  Vehicles eligible for  a carbon  monoxide  waiver to  7.0  gpm at
     low altitude are eligible for a waiver to 11 gpm  at high  altitude.

 11  Standards in parentheses apply to vehicles sold  in specified high altitude
     counties.   Further,  these  are the statutory  standards  according  to the
     1977 Clean Air Act amendments.

 gpm - grams per mile
 CID - cubic inch displacement
 CVS-72 - constant volume sample cold  start test
 CVS-75 - constant volume sample test which includes cold  and  hot  starts
 7-mode - 137 second driving cycle test

8   Standards in parentheses  apply to  trucks  sold in specified  high  altitude
    counties.

9   Standards in parentheses  apply to  trucks  sold in specified  high  altitude
    counties.   Further,   these  are  assumed  to  be  the  statutory  standards

3    Hydrocarbon emissions  from 1975-76 limited  production vehicles may
     not exceed 1.5 gm/mi.

4    Hydrocarbon standards  in  parentheses indicate  total  hydrocarbons.
     When  applicable,  manufacturers  may  elect  to  certify  vehicle  to
     either the non-methane or total hydrocarbon standards.

5    For the  1981  model year, manufacturers may  choose either option  A
     or  B  lor their  entire 50,000  mile  certified  product  line.  The
     option chosen in 1981 must be retained for the 1982 model year.

6    100,000  mile  options:  Option 1  standards  refer   to  the projected
     50,000 mile  emissions  for hydrocarbons  and carbon  monoxide  while
     Option 2  standards refer to the projected 100,000  mile emissions for
     these pollutants.  NOx  emission  standards for both options refer  to
     the 100,000 mile projected emissions.

                               Appendix B

                       CALCULATION OF THE VMT MIX

The  proportion of  the  total  vehicle-miles-traveled   (VMT)  driven  by a
given  vehicle  type  depends  entirely  on (a)  the  number  of  vehicles,
(b) the model year registration distribution, and (c)  the mileage accumu-
lation rate  distribution.   Also,  as  light  duty  diesel  powered vehicles
and  trucks become  a larger proportion  of  their respective fleets,  their
VMT  proportions  will increase.  As  the diesel powered  vehicle type  VMT
fractions increase,  the  corresponding  gasoline powered  vehicle type  V1IT
fractions will decrease.

The MOBILE2 computer program calculates the VMT mix; unless a user  inputs
locality specific information.  The calculation procedure is based  on  the
estimated number of vehicles and the average annual miles driven for each
vehicle  type.   The  product  of these  two variables estimates  the  total
miles driven on  January  1  of  a calendar year  for each vehicle type.  3y
performing  this  calculation  for  each  vehicle   type  and  summing  the
results,   the  total  miles  driven on  January 1  for   the  entire   highway
mobile   source   fleet   are  estimated.   Finally,   by  normalizing   the
individual vehicle type total miles,  the VMT  fractions  are  estimated.

Specifically,  the MOBILE2  computer program  performs  the calculations in
subprogram TFCALX with the following equations:

         MILES(IV) = VCOUNT(IV)*DAF(IV)*TFNORM(IV)
         TOTVMT  SUMiv[MILES(IV)]
         VMTMIX(IV) - MILES(IV)/TOTVMT
where
     TOTVMT     is the total miles  traveled by the entire highway  mobile
                source fleet.

     IV         is the  vehicle  type  index  (1 -  LDGV,  2  =  LDGTl,  3  =
                LDGT2, 4  = KDGV, 5 -  LDDV,' 6 = LDDT, 7 - HDDV,  and 8  =
                MC).

     VMTMIX(IV) is the estimated VMT fraction for vehicle  type IV.

     VCOUNT(IV) is the estimated  vehicle  count for vehicle type IV based
                on 1978  registrations.   To  use  the dieselization  rates,
                VCOUKT(l)  = VCOUNT(5)  and  VCOUNT(2)  =  VCOUNT(6).   This
                implies that the LDDVs and  LDGVs  are  combined to  become
                the light  duty  vehicle  fleet.   Similarly,  the LDGTls  and
                LDDTs are  combined  to  become the light duty  truck  fleet.
                Both the light  duty vehicle  and  truck  fleets  are  adjusted
                by fleet  sales  fractions  to separate the diesel from  the
                gasoline powered vehicles/trucks.

     DAF(IV)    is the  dieselization rate  adjustment  factor  for  vehicle
                type IV.   DAF(3)  =  DAF(4)  - DAF(7) = DAF(8)  = 1.0; which
                implies no dieselization adjustments  are  made for these

                               Appendix C

          CALCULATION PROCEDURE TO COMBINE THE EMISSION RESULTS
          OF THE TWO LIGHT DUTY GASOLINE POWERED TRUCK CLASSES

Frequently  air  quality  analyses  require  the  use  of  one  light  duty
gasoline powered  truck vehicle type as  opposed to  two.   However, emis-
sion factors are  presented  for two truck types:  LDGT1 and LDGT2.   As* a
result, a procedure has  been  developed which will  combine  the  two truck
types.  This  appendix describes  this procedure.   The  procedure  simply
combines the calculated emission factors of  each  truck type on the basis
of VMT.  To illustrate this, a hypothetical example  is used.

Suppose that  on  January 1,  1985,   the  LDGT1  and  LDGT2   calculated  CO
emission factors are 32.57 and 22.09  grams/mile;  respectively.   Further,
assume that the  LDGT1 and LDGT2 proportions of  the total  fleet  VHT are
7.9'  percent and  4.6  percent; respectively.   Finally  assume  that  the
entire fleet travels 4.1  billion miles.

From this example it is obvious that  the combined truck types travel the
following miles on January 1,  1985:

     (4.1 x 109 miles) (.079)  + (4.1 x  109 miles)  (.046)

Further,  the  total  grams  emitted by  the  combined  truck  types  are  as
follows:

(4.1 x 109 miles) (.079)  (32.57 g/mi) + (4.1  x 109 miles) (.046) (22.09 g/mi)

As a result, the calculated CO gram/mile emission factor estimate  for the
combined truck type is as follows  (total  grams/total miles):

(4.1 x 109 miles) (.079)  (32.57 g/mi) + (4.1  x 109 miles) (.046) (22.09 g/mi)
(4.1 x 109 miles) (.079)  + (4.1 x  109 miles)  (.046)

or,

(.079) (32.57 g/mi) + (.046)  (22.09 g/mi)
             (.079) + (.046)

After simplifying the  equation it becomes obvious 'that the combined LDGT
vehicle type is a function of  the calculated emission factors and  the VMT
fractions.  The more generalized formula  is  as  follows:

VMT(LDGTl) x EF(LEGTl) + VHT(LDGT2) x EF(LDGT2)
             VMT(LDGTl) + VMT(UDGT2)

                               Appendix D

         METHODOLOGY FOR CALCULATING JANUARY 1 TRAVEL WEIGHTING
           INFORMATION AND FLEET AVERAGE MILEAGE ACCUMULATION

This  appendix  describes  the  derivation   of  January  1   registration
distributions, the annual rate of mileage accrual for the fleets, and the
fleet  average  mileage   accumulation  distributions.   The   January  1
registration and annual rate of mileage accrual distributions are used in
the calculation of travel weighting fractions.  The fleet average mileage
accumulation distributions are  used to  estimate  the January 1 emission
levels by model year.

D.I  JANUARY 1 TRAVEL WEIGHTING  INFORMATION

The  travel  weighting  fractions  for  a  given  vehicle  type  are  the
individual model year proportions  of the  total VMT for the vehicle type.
To generate the travel weighting fractions, typically three distributions
are  required:  (1) the annual  mileage  accrual rate  per  vehicle  by age
distribution, (2) the registration distribution,  and (3)  the fleet sales
fraction distribution (to account for  the influx of diesels).

D.I.I  January 1 Registration Distribution Transformations

A portion  of  the  January 1  travel fraction .calculation  procedure  is to
estimate  the  January  1  model  year  registration distribution  for  each
vehicle  type.   The  model   year  registration  distribution,  frequently
referred to as the registration mix, begins with  all model years combined
for a given vehicle type and apportions them  into their appropriate model
year index (except  for model year index 20 which  represents  all model
years that were built 20 or more model  years  ago).   At this  phase of the
registration mix  development,  the LDV  and  LDT  model  year  registration
distributions  are  composed  of  both  the  gasoline  and   diesel powered
vehicle types.

For the EPA MOBILE2 computer program, the initial model year  registration
distributions  are assumed to  be  based  on -July 1 data.    This  July 1
information is  then transformed into January 1  model year  registration
distributions.  For vehicle  types  where model year sales are assumed to
begin on October  1  (light duty  vehicles and  trucks), the original July 1
model  year  registration  distribution  accounts   for  approximately 75
percent of the current model year  fleet.  Using the assumption  of uniform
sales throughout  the year, approximately 25  percent would have been  sold
by January 1 (or  one-third of the  July  1 registration).  The older model
year registration figures are six months older on July 1 than they are on
January 1.  However, no  direct  adjustment are made to these older model
year registration figures.  Although the difference between January 1 and
July 1  for the older  model  vehicles  is primarily  scrappage,  the  older
model year registration figures  are adjusted  later.

Denoting  the  July 1 registration  fractions  as R(l), R(2), R(3),  .   .  .,
R(20+), we can generalize the January  1  adjustment equations  as  follows:

-------
                                   D-2

FIRST MODEL YEAR INDEX: 1/3*R(1)
SECOND AND LATER MODEL YEAR INDEX:  R(i),  1=2,  3,  ....  20+

The second  type  of adjustment for the January  1 model year  registration
distributions  is   to   account   for   the  fleet  sales  fractions:    The
separation  of the model  year  sales  into diesel  and  gasoline  powered
vehicle types.  The fleet  sales fractions  are given in each table  .48  of
Appendix  E.   As   a   result,  the  January  1  model   year   registration
distributions are adjusted according  to the following formulation:

FIRST MODEL YEAR INDEX: l/3*R(l)*F(my)
SECOND AND LATER INDEX: R(i)*F(my-i+l)

F(my) is the fraction of the model year sales which are gasoline powered,
if calculating the LDGV or LDGT registration distributions.  F(my)  is  the
fraction of the model year sales which are diesel powered, if  calculating
the LDDV or LDDT registration distributions.

The last  adjustment to  estimate the  January  1 model  year  registration
distributions is  to normalize the distribution such that the  fractions
sum to  one.  To accomplish  this  adjustment,  the  following  procedure  is
used:

DAF = SUMi[P(i)*R(i)*F(myi+l)]

where   P(l) =1/3
        P(l) =1  i - 2, 3	20+
        R(i)  July 1 registration  figures
             i - 1, 2,  3,  . . .,  20+

        F(my-i+l)  the fleet sales fraction for model year my-i+1

and     SUM! = the summation over the  20  model years.

Then each January 1 registration P(i)*R(i)*F(my-i+l) figure is divided  by
DAF to estimate the January 1 registration  mix.

For vehicles  whose model year  sales begins on January  1  (heavy duty
vehicles  and  motorcycles),   there   are   two   changes   to   the   above
normalization procedure.  P(l) should  be set  to zero and  every F(my-i+l)
term should be set to 1.

D.I.2   January 1 Annual Rate of  Mileage Accrual  for  the  Fleet

The  last  aspect  of  calculating  the  travel  weighting  fractions   is
determination  of   the  January  1  annual rate  of  mileage  accrual.   The
methodology for calculating the average mileage accumulation rate  will  be
explained by  the  following  example:  Calculation  of  the  average  annual
mileage  accumulation  rate for  the   1985  model  year  (MY)   vehicles   on
January 1 of 1985,  1986, 1987 and later years.

First the average  annual  mileage  accumulation rate of  the 1985 MY  light
duty vehicles on January  1,  1985,  will  be calculated  (the calendar year
when the  vehicle model year  index is one).  It is  assumed that  mileage

-------
                                   D-3.

accrual is  uniform throughout the  year and  that 1985  light  duty model
year sales begin on October 1, 198A.

Using these assumptions, it is obvious  that  by January 1, 1985, all  1985
MY  vehicles  are less  than one  year old  and accumulate mileage  at  the
first year  rate.   The  annual rates of  mileage accural  are  presented  in
table  .4  or  .4A for  each vehicle  type.   For  the  light  duty gasoline
powered vehicles,  the   annual  mileage  accrual  rate  for  vehicles during
their first year is 14,400 miles.

By January 1, 1986, those  vehicles  that had  been  sold by January 1,  1985
have been  on the road  for an additional  year and  accumulate  mileage  at
the second year annual  rate of 13,900 miles.

In addition to the 1985 model year vehicles  sold  before January 1,  1985,
those 1985 MY vehicles sold after January 1  and  before  October 1,  1985,
must be  considered.   Again by  assuming uniform  sales,  approximately  75
percent of the  1985 model year vehicles are  sold after  January 1,  1985.
Further, on January 1,  1986 these vehicles are still in their  first  year
of  mileage accumulation  and  are  accumulating  mileage at a 14,400  mile
annual rate.  

Since  the  first group  represents three months of sales  and  the  second
group represents nine months of  sales,  the average  annual mileage  accrual
rate of 1985 MY vehicles on January 1, 1986 can be expressed  as  follows:

(.25)*(13,900) + (.75)*(14,400)

By  extension,  the  formula  for  the  average  mileage accumulation rate  of
the 1985 MY vehicles on January 1, 1987  is as follows:

(.25)*(13,400) + (.75)*(13,900)

Denoting  the average  annual  rate  of mileage accrual  during  the  first,
second,  and  third year   as  M(l),  M(2),  and  M(3);  respectively,  the
generalized average annual mileage  accumulation rate  equations  on  January
1 are as follows:

FIRST MODEL YEAR INDEX: M(l)

D.2  JANUARY' 1 FLEET AVERAGE MILEAGE ACCUMULATION

To  estimate  the  emission  levels  on January  1 for each model year  (as in
tables .2A through  .2C for each  vehicle type),  the annual mileage  accrual
rate per vehicle by age distribution is used to  derive  the  fleet  average
mileage accumulation distribution.

-------
                                   D-4

The  methodology  for calculating the  average January  1 fleet  cumulative
mileages  will  be  explained  by  example:   Calculation  of  the  average
cumulative mileage for the 1985 model  year  (MY)  vehicles on January 1  of
1985, 1986, 1987, and later years.

First, we  calculate  the  average fleet cumulative mileage  of the  1985  MY
LDGVs on January  1,  1985 (the calendar year when  the vehicle model year
index is defined as one).

We  assume  vehicle  sales are  uniform throughout  the  year,  the  mileage
accrual is uniform throughout  the  year,  and  the  1985  model year  sales
begin on October 1, 1984.

Using  these  assumptions,  it  is  obvious  that  by  January  1,  1985  (25
percent of the way through the sales year), approximately  25%  of the 1985
model year vehicles will be sold.   These  vehicles  range in age  from 0  to
3 months.  Assuming uniform sales,  their  average  age  is 1.5 months.

Therefore,  the  average mileage accrual for  these  1985 MY  vehicles  which
have been  sold  by January  1,  1985, is 1.5/12, or  .125, times  the annual
rate of mileage accrual  for the first  year.   The annual rates  of  mileage
accrual are  presented in  table .4  or .4A  for  each  vehicle type.   For
LDGVs  the  annual  mileage  accrual   rate  for vehicles  during their  first
year is 14,400 miles.

By January 1, 1986,  those vehicles  sold  before January 1,  1985  have been
on  the road  for  an additional  year.   Therefore,  those  vehicles have
accumulated mileage  for  l+(1.5/12) years, or  1.125  years.  Referring  to
table .4A or .4 for the annual rates of mileage  accrual, we can calculate
the average cumulative mileage of  these vehicles as  the sum of  the  first
year's mileage (14,400 miles) plus  .125 times  the second year  annual rate
(13,900 miles).

In addition to the  1985  model year vehicles sold before January 1,  1985,
we must consider  those 1985 MY  vehicles  sold between January  1,  1985  and
September 30, 1985.  If we again assume uniform  sales,  then by. January 1,
1986 these vehicles range in age   from  3 months  to 12 months,  with  an
average age of 7.5 months.   Since these vehicles are still in their  first
year of  use on  January  1, 1986,  their  average mileage accumulation  on
that date is 7.5/12, or .625,  times 14,400 miles.

The average cumulative mileage of all  1985 MY  vehicles  on  January 1, 1986
is  the  sales  weighted average  of  the cumulative mileages for  these  two
groups  of  vehicles  (those  sold before  January  1  and  those sold  after
January 1).

Since  the  first  group represents  three  months  of  sales  and  the second
group  represents  nine months  of  sales,   the  weighted  average  cumulative
mileage  of 1985  MY vehicles on  January 1,  1986  can be  expressed  as
follows:

     .25*[14400 +  .125*13900]  + .75*[.625*14400]

-------
                                   D-5

By extension, the formula  for the cumulative mileage  of 1985 model  year
vehicles on January  1,  1987 is given by:

.25*[14400 + 13900 + .125*13400]  + .75*[14400 + .625*13900].

Denoting  the average  rate  of  mileage  accumulation  during  the  first,
second, and  third years as M(l),  M(2),  and M(3), we  can generalize  the
equations for cumulative mileage  on January 1 as follows:

FIRST YEAR:  .125*M(1)
SECOND TEAR:  .25*[M(1) + ,125*M(2)J + .75*[.625*M(1)]
THIRD YEAR:  M(1)+.25*[M(2)+.125*M(3)]+.75*[.625*M(2)]
Ith YEAR:  M(1)+M(2)+...-H!(i-2)+.25*[M(i-l)+.125*M(i)]+.75*[.625*M(i-l)]

For vehicles whose  sales year begins  on January  1  (heavy duty  vehicles
and motorcycles) the formulae are modified as follows:

FIRST YEAR:  0
SECOND YEAR: .5*M(1)
THIRD YEAR:  M(l) + M(2) + ... + M(i-2) + .5*M(i-l)

                               Appendix F

              SAMPLE CALCULATION OF MOTOR VEHICLE EMISSIONS

This appendix presents the procedure  for calculating emissions  factors  in
a  step-by-step  manner.  Although  most users  of motor  vehicle  emission
factors should rely on computerized calculations (such as MOBILE2),  this
sample calculation may prove useful  to  those  becoming familiar with  the
methodologies presented in this document.

For  this  sample  calculation,  the  light  duty  gasoline  powered  vehicle
(LDGV)  hydrocarbon emissions  for  January  1,  1985  are  computed.    An
ambient temperature of 80F  is assumed.   Although this HC calculation  is
only for  the LDGVs, it is designed to give  the  user an understanding  of
the  logical  sequence  of  calculations.    The emission factor  calculation
procedure of the  other vehicle  types  follows  the same logical sequence;
however, the equations may differ.

An  inventory  of motor vehicle  sources  of  hydrocarbon  emissions  should
include emissions  from the  eight  vehicle types.  For each vehicle  type
the  exhaust emission  factors  should be calculated  with  the  equation
presented in the  corresponding  chapter.   The  resultant exhaust  emission
factors multiplied by  the fraction of vehicles-miles-traveled  (VMT)  for
the  respective  vehicle types  will  sum to the average gram/mile  exhaust
emission  levels  from  the  entire  highway  mobile   source  fleet.   For
hydrocarbon  emission  estimates,   the   crankcase   and  evaporative   HC
emissions are calculated  and added to the exhaust HC  emissions estimates.

F.I  DATA REQUIREMENTS

Before  determining  what  data  are  required,  the user  should  review  the
conditions under which vehicles  are tested in order to ascertain whether
these  conditions  differ  from  the  locality specific ambient  temperature,
average  speeds,  and vehicle operating modes  (see Section  .A.I  in  each
chapter).

The user should determine the following locality specific  data:

     1. Ambient temperature.

     2. Fraction  of  January 1 travel,  by model year,  for each  vehicle
        type  (model  year  registration  distributions  and  fleet  annual
        mileage accumulation rates)

     3. The VMT mix.

     4. Percent of VMT in cold  start and hot  start  operating modes  for
        light duty vehicles, light duty trucks, and motorcycles.

     5. The calendar year of study  (January 1 of that year).

     6. Any  other  data  required   to   utilize  additional   (optional)
        correction factors.

-------
                                   F-2

F.2  DATA USED TO CALCULATE HC EMISSIONS

For this sample calculation, the following conditions are assumed:

     1. Ambient temperature is 80F.

     2. National statistics on  average fleet annual  mileage accumulation
        rates and vehicle registration by model year are used.

     3. The  total  hydrocarbon  emissions  (as opposed to non-methane  HC)
        are calculated for the speed of 30 mph.

     4. The  percentages  of VMT in  the  cold  start,  stablized,  and  hot
        start  operating  modes   are assumed  to  be  40%,  30%,  and  30%
        respectively,  for   light   duty   vehicles;   both   catalyst   and
        non-catalyst.

     5. The calendar year of study is 1985.

     6. All  other  conditions  are  assumed to  match  the vehicle  testing
        conditions.

F.3  CALCULATION OF EXHAUST EMISSION FACTORS

The equation to calculate  the   exhaust  hydrocarbon  emission factor  for
LDGVs as discussed in Chapter 1, is given as follows:

             BEFnpstwx - SUMi(BERipn* [NMi] *TFi*Ripstwxn*
                              [ACCFipt*ELCFip*TTCFip*HCF]-K:CEVi*TFln)


Since the air  conditioning  usage (ACCFipt),  extra load  (ELCFip),  trailer
towing  (TTCFip), and humidity level for  NOx (HCF) are  assumed to match
the basic test conditions, they are  set equal  to 1.0 (i.e.,  they have no
effect  on  the  calculations  and  may  be  disregarded).   Similarly,   the
non-methane fraction (NMi) can be set to 1.0 since total HC emissions  are
being calculated.

Only four  factors  are of  concern in  this sample  calculation:   (1)  the
basic exhaust  emission  level  (BERipn);  (2)  the model  year fraction  of
annual' travel (TFin);  (3) the speed/temperature/operating-mode  correction
factor  (Ripstwxn);  and  (4)  the crankcase  and evaporative  HC  emission
level (CCEVi).  Refer to Chapter 1 for a full explanation of the  emission
factors equation.

F.3.1  Basic Exhaust Emission Levels (BERipn)

The basic exhaust  emission  levels for LDGVs are  the emission levels  per
mile;  assuming  the  basic test  conditions.   The  HC  emission  levels  on
January 1,  1985 are  given in  Table 1.1.2A.  These BERipn values  are also
listed in Table F-l and will be  used to calculate  the tailpipe  exhaust HC
emissions.

-------
                                   F-3

F.3.2  Travel Weighting Fractions (TFin)

In order to calculate the fraction of annual travel by model year  (TFin),
the fraction of  in-use  vehicles  by model year are  weighted  on the  basis
of annual rate of mileage accumulation.  In many cases, locality specific
data on automobile use  and  registration  are readily available.  Whenever
possible,   local  data  should be used.   However,   for  purposes of  this
sample calculation,  the  national average fraction  of  annual travel  from
Table 1.1.5 will be  used.   The  TFin values are also  listed  in Table F-l
to be used for calculating  the exhaust HC emissions.

F.3.3  Speed/Temperature/Operating-Mode Correction Factor  (Ripstwxn)

Although  the  speed/temperature/operating-mode correction factor  can be
calculated manually  using  the  generalized  equations  in Chapter  1, the
computer program, MOBILE2,  was used to generate the Ripstwxn values  for  a
cold/stable/hot mix  of  40%/30%/30%,  an ambient temperature  of 80F, and
an average  route speed of 30 mph.  The appropriate  Ripstwxn values are
listed in Table F-l.

F.3.4  Calculated Tailpipe  Exhaust Emission  Factors

The  final  step in the  calculation of the  tailpipe  exhaust HC emission
factor for LDGVs is  to multiply  the mean emission levels, travel factors,
and correction factors for  each  model year and then  sum the products.

This procedure is also shown in  Table F-l  depicting the calculation  of  a
tailpipe exhaust  HC  emission factor  for LDGVs.  The  emission factor is
expressed in units of grams per  vehicle mile traveled.

If the pollutant were CO or  NOx, no further calculations would be  needed
to estimate the  total  exhaust emission factor.  However,  for HC emission
estimates the additional calculations in Sections F.3.5 and  F.3.6  need to
be performed.

F.3.5  Crankcase and  Evaporative HC Emission Levels  (CCEVi)

To calculate  the crankcase and   evaporative  HC emission level, the  model
year  total crankcase  and  evaporative  HC  emission  levels   (CCEVi) are
required from  Table  1.1.IB.   Further, the  fractions  of annual travel by
model year (TFin) are required (the same as in Section  F.3.2).  The  final
step in this  procedure  is  to multiply the  average  CCEVi  levels with the
annual travel model year fractions, TFin, and then sum the products.

This procedure is  shown in Table  F-2 depicting the  calculations  of the
crankcase  and  evaporative  HC emission  factor for  LDGVs.   The emission
factor is expressed in units of  grams per vehicle mile traveled.

F.3.6  Total HC Emission Factors (BEFnpstwx)

Slimming the emission factors from  Sections  F.3.4 and F.3.5 will result in
the  total  HC emission  factor.   For  this  example  the  total HC emission
factor is 2.534 grams/mile  (2.095 + 0.439).

                               Appendix 6

         NATIONAL AVERAGE EMISSION FACTORS FOR HIGHWAY VEHICLES

Light  duty  vehicles,  light  duty  trucks,  heavy  duty  vehicles,  and
motorcycles comprise  the four  main types  of highway  vehicles.  Within
each of these types, the number of engine cycles and fuel type  results  in
different emission characteristics*   For .example, vehicles may  be  powered
by either gasoline or diesel fuel.

It is also important to note that highway vehicle emission factors change
with time and, therefore, must  be calculated for a specific time  period.
The major reason  for  this time dependence  is the gradual replacement  of
vehicles with  older emission  control  equipment  by vehicles  with  newer
control  equipment,   as  well  as  the  gradual  deterioration  of  vehicle
emissions as they accumulate mileage.

This  appendix contains  average emission  factors  for  several  calendar
years  between  1975 and  1995 for  various  ambient  temperature,  cold/hot
start  VMT  weighting,  and  average  speed  combinations.  This  appendix
includes one case that  represents  the average  national emission  factors
aa generated from the basic test conditions  (in Tables G-3, G-9,  and G-15.
for HC, CO, and NOx; respectively) as well as other scenarios  that can  be
used to assess the  sensitivity  of the  emission factors  to changing  input
conditions.   All  emission  factors are  given  in units   of  grams  of
pollutant  per  vehicle  mile traveled.    The  hydrocarbon emission levels
include the crankcase and  evaporative  HC emission results.  Further,  the
hydrocarbon emissions are total, rather than non-methane.

Emission factors  presented  in this  section  are  intended to assist  those
individuals interested  in  compiling  approximate mobile source  emission
estimates for  large areas,  such as an individual  air  quality  region  or
the entire nation.

The emission factor calculation techniques  presented in  this document  are
strongly recommended for  the  formulation of  localized emission estimates
required for air  quality modeling or  for the evaluation of air pollutant
control  strategies.   Many  factors,  which  vary  with  geographic  location
and  estimation situation,  can  affect emission  estimates  considerably.
The  factors  of   concern  include average  speed,   percentage   of  VMT  in
cold/hot start vehicle  operation,  percentage of  travel  by vehicle  type,
ambient  temperature,  air  conditioning  usage,  vehicle  load,   trailer
towing,  and humidity.   Clearly,, the  innumerable  combinations  make  it
impossible  to  present   mobile   source   emission  factors   for   each
application.   An  effort has  been  made,  therefore, to  present  emission
factors  for  a   range  of  conditions.   The  following conditions  are
considered for each of these cases:

     1. Each  table  represents  one  average  speed.   There  are  6  basic
        tables with speeds of 5.0,  10.0,  19.6, 35.0, 50.0, and  55.0 mph.

     2. Each table  presents six calendar years:  1975,  1980,  1982,  1987,
        1990, and 1995.

-------
                                   G-2

     3. Each calendar year presents  30  combinations of  five  temperatures
        and six operating modes.  The five temperatures  are 0,  25,  50,
        75, and 100F.  The six operating mode  combinations  (percent  VMT
        in  a  cold  start,  non-catalyst;  percent  VMT  in  a  hot  start,
        catalyst;  and  percent  VMT  in a  cold  start, catalyst) are  0/0/0;
        0/27.3/0;  0/100/0;  20.6/0/20.6,  20.6/27.3/20.6; and  100/0/100.

     4. The VMT  mixes are  those calculated  from MOBILE2.   They are  as
        follows:

        Calendar Year    LDGV/LDGT1/LDGT2/HDGV/LDDV/LDDT/HDDV/MC
           1975          .786/  .083/  .047/.042/.000/.000/.033/.009
           1980          .781/  .083/  .047/.042/.005/.001/.033/.009
           1982          .773/  .082/  .046/.042/.013/.002/.033/.009
           1987          .729/  .077/  .046/.042/.056/.007/.033/.009
           1990          .693/  .073/  .046/.042/.092/.012/.033/.009
           1995          .647/  .069/  .046/.042/.138/.017/.033/.009

Each  table  presents emission  factors for  the  30  combinatons  discussed
above  for  the  six  calendar  years  between  1975 and  1995.    The  table
entries were calculated using the techniques described and data  presented
in this document.   Examination  of  the tables indicate the sensitivity of
the emission factors to various conditions.  A user who  has specific data
on the input factors should calculate a  emission factor to fit  the  exact
scenario.  When specific input  factor data are not  available,  however,  it
is hoped that the range of values  presented  in the tables will  cover  the
majority of  applications.   The user should be  sure that the  appropriate
scenario is chosen to fit the  situation  under  analysis.
