              Air Quality Analysis for the Revised Gaseous
              Emission Regulations for 1984 and Later Model
              Year Light Duty Trucks and Heavy Duty Engines
Introduction
This report  describes  the analysis  performed  by the Test  and Evaluation
Branch to support the revised  1984  and later model year  light duty truck
(LOT) and heavy duty engine  (HDV) CO  regulations being considered  by the
Standards Development and Support Branch.   This  analysis  examined the air
quality  impact  of such  regulations in  both low and  high  altitude  non-
California areas  under  the  presence of  inspection and maintenance  (I/M).
Six  strategies  are  examined in  this analysis.  These six  strategies are
as follows:

1)  The  1984+ LOT and HDV CO standards at low altitude are  assumed to be
    10  grams/mile (gm/mi) and 15.5  grams/brake horsepower-hour  (gm/bhp-
    hr), respectively.  Both vehicle types are assumed to have a 10  per-
    cent AQL  SEA  program beginning  with the 1984 model  year.  The 1983+
    light duty vehicle (LDV) CO standard is assumed to be 3.4 gm/mi.

2)  The  1984+  LOT and HDV  CO standards  and regulations  at  low  altitude
    are  assumed to  be  identical  to  strategy one.  The difference  is the
    assumed 1983+ LDV CO standard at 7.0 gm/mi.

3)  The  1984+ LDT and HDV CO standards at low altitude are  assumed to be
    10  gm/mi and  35  gm/bhp-hr,  respectively.   Both vehicle types  are
    assumed to have a 40  percent  AQL SEA program implemented.  The  imple-
    mentation model year is  1984  for the LDTs  and 1986  for the HDVs.   The
    1983+ LDV CO standard is assumed to  be 3.4 gm/mi.

4)  The  1984 LDT and HDV  CO  standards  and regulations  at  low altitude are
    assumed to be identical  to strategy 3.  The  difference is the assumed
    1983+ LDV CO standard at 7.0 gm/mi.

5)  This high  altitude  strategy assumes  the  1984+  LDT CO standard  is 14
    gm/mi.   The 1984+  HDVs  are assumed  to be the low altitude vehicles,
    reflected  in  strategies  1 and  2,  operating  at high  altitude.   Also,
    no  specific  high altitude SEA  programs are  assumed.  The  1983+  LDVs
    are  assumed to have a 7.8  gm/mi  CO standard.

6)  This high altitude  strategy also assumes the 1984+ LDT CO standard is
    14  gm/mi.   The  1984+  HDVs  are  assumed  to  be  the  low  altitude
    vehicles,  reflected in  strategies 3 and  4,  operating at  high alti-
     tude.  No  specific  HDV high  altitude standards  are assumed.   Also, no
    specific high altitude SEA programs  are assumed.   Identical to  strat-
    egy  5 is the assumption of a 7.8 gm/mi CO standard on the 1983+ LDVs.

A  total  of six runs  resulted  from  the  six strategies  being  analyzed at
low and  high altitudes, with I/M.

This report is presented in  two parts.   The first part presents the anal-
ysis performed  to estimate  CO emissions from the highway mobile sources
while  the  second  part  presents  the  assumptions  and results  of  the  air
quality assessment.

-------
1.  Highway Mobile Source CO Emissions

This  part  presents  the  analysis  performed  to estimate  the CO  emission
levels.  The analysis performed  is described  in four  sections.   The first
section presents  the scenario  information used to  run the MOBILE2  com-
puter programfl].  Section two  details how MOBILE2  and  the basic emission
rates were modified  to  perform the analysis[2].  Section  three describes
in  detail  the  six  strategies  examined,  and section  four presents  the
MOBILE2 results.

l.A  General MOBILE2 Scenario Information

In total, six runs  were  performed with a  modified  MOBILE2 program:  Four
runs for the low altitude non-California region and  two runs for the high
altitude  non-California  region.   Each  region had  only   I/M  runs  per-
formed.  Each run  examined  only highway mobile source  CO  emission levels
(in  grams  per  mile).  Also,  each run projected  the emission  levels  for
calendar years  1977, 1985,  1987, 1988, 1990,  1995,  and  2000.   Finally,
each run was performed  such  that  only  the basic exhaust  emission levels
were  output.   That  is,  all  correction  factors were assigned  such  that
they would have no effect on  the emission results.

Since all runs  included  the  benefits of I/M, the  characteristics  of  the
I/M programs assumed are as follows:

1)  The I/M programs begin on January 1, 1982.

2)  The LDGT and pre-1981 LDGV I/M stringency rate is 30 percent.

3)  The I/M programs have a functioning mechanics training program.

4)  All 1968 and later model  year vehicles and  trucks are  affected by the
    I/M programs.

5)  The LDGV, LDGT1,  and LDGT2 vehicle  types are  tested in the  I/M pro-
    grams.

6)  There  is  a  70 percent  identification rate for  the  1981  and  later
    model year LDGVs.

l.B  MOBILE2 Modifications

MOBILE2 was modified in two  areas to perform the  runs necessary  for  the
revised LOT and HDV CO regulations:

1)  I/M technology groups, and

2)  Alternate emission rates  for various model years and vehicle types.

The  I/M subprograms  were altered  to  increase the  number  of  technology
groups from three  to five.    Also,  the  subprograms  were altered  to  rede-
fine,  by  vehicle type,  the   I/M  credits used.   The  following  technology
group definitions are used in this analysis:

-------
1)  Technology 1:  Pre-1975 LDGVs, pre-1975 LDGTls, and pre-1979 LDGT2s.

2)  Technology 2:  1975-1980 LDGVs, 1975+ LDGTls, and 1979+ LDGT2s.

3)  Technology 3:  Undefined.

4)  Technology 4:  1981 LDGVs.

5)  Technology 5:  1982 LDGVs.

6)  Technology 6:  1983+ LDGVs.

Alternate I/M credits are  used in the runs to accredit  the  emission rate
and  technology  differences  between  this analysis  and those  in MOBILE2.
Appendix  A presents  the  alternate  I/M  credits  used  for  the  different
strategies.

Except  for  the  1984+ LDGT and HDGV CO  emissions,  and the  1983+ LDGV  CO
emissions» other low altitude  model  year and/or  vehicle type CO emissions
differ  from those  in MOBILE2 as  a  result of expected  changes  in regula-
tions,  technology mix, and/or  emission data.   The emissions  from the 1981
and  1982  LDGVs   are  different  from  those in  MOBILE2  as  a  result  of  an
expected   change in  the  technology mix.   The   emissions  from  the 1979
through 1983  HDGVs are  different from  those  in MOBILE2  as a  result  of
more current emission information.

Similarly,, some  high altitude  model  year and/or  vehicle type CO emissions
differ  from those  in MOBILE2 as  a  result of expected  changes  in regula-
tions,  technology mix, and/or  emission data.   For the  most part, the high
altitude  CO emission  rates change as  a  result of the changes  to  the low
altitude  vehicle types.    However,  the 1984+  LDDV and LDDT  CO emissions
and  the  1983+   LDGV  CO  emissions  change  since  the   emission  standards
assumed are different  between  this analysis  and  MOBILE2.   MOBILE2 assumes
these  vehicle  type  emission  standards  equal   their  corresponding  low
altitude  vehicle  type  emission  standards.   The  proportional  emission
standards are assumed for  this analysis.

Except  for the  emissions  from  the  1983 and later  LDGVs,  and  the  1984+
LDGTs  and HDGVs, the  emissions  given  in Table   1  are used  in  every low
altitude  strategy.  Similarly, the emissions given in  Table  2 are used  in
every  high altitude strategy, except  for the 1984+  LDGT and  HDGV  emis-
sions.

l.C  Strategies  of Analysis

Six  strategies  are examined in  this analysis.   These  six strategies are
discussed  below in six  subsections.  Within  each subsection,  the  basic
exhaust  emission  rates,   emission  standards,  SEA program,  useful  life
definition, and  technology mix  for  the  1984 and later model  year  LDGTs
and HDGVs are discussed.   These  five components  are summarized in Table  1
for  all low altitude  strategies  and  Table 2 for  all high altitude  strat-
egies.

-------
1)  Strategy One - Low Altitude Base Case for Option 1

    This  strategy represents  the  current  set  of  low altitude  non-
    California LDV,  LOT,  and HDV  CO  regulations.   That is,  the  1983
    and later model year LDV regulations  require a  3.4 gm/mi CO emis-
    sion standard, a 40%  AQL SEA program, and a one-half  useful  life
    definition.   The  expected technology  mix is assumed  to be  59.2
    percent closed loop throttle body,  10.2  percent closed loop carb-
    ureted,  and  30.6  percent  open  loop carbureted  systems.   This
    technology mix is different from the MOBILE2 technology mix.

    The regulations for the  1984  and  later model year  LDTs  require a
    10 gm/mi CO emission  standard,  a  10% AQL SEA program, and  a  full
    useful  life  definition.   The  expected technology mix is assumed
    to be  100  percent  oxidation  catalysts.  No  threeway catalysts are
    assumed in this analysis.

    The  1984  and  later  model year HDVs  have  the  following regula-
    tions: A 15.5  gm/bhp-hr  CO emission standard,   a  10% AQL SEA  pro-
    gram, and a full useful  life definition.  There is expected to be
    a  100  percent  oxidation  catalyst  technology  mix.    No  threeway
    catalysts are assumed in this analysis.

    The technology mixes  given above  are for the gasoline  powered, as
    opposed  to diesel  powered,  vehicle  types.   The emission  rates
    along  with  the other  regulations  mentioned above  are summarized
    in Table 1.

2)  Strategy Two - Low Altitude Base Case  for Option 2

    With  two  exceptions,  strategy  two  is identical to  strategy  one.
    The two exceptions are as follows:

    1)  The 1983  and later model  year  LDV  CO  standard is  7.0  gm/mi
        instead of 3.4 gm/mi.

    2)  The 1983  and  later model year LDGV  technology  mix is estima-
        ted to be 5.3  percent  closed  loop throttle  body,  57.9 percent
        closed loop carbureted, and 36.8  percent open loop carbureted
        systems.

    These  differences  are summarized  in Table 1 along  with, all  other
    revised MOBILE2  CO emission  rates  and  regulations  used in  this
    strategy.

3)  Strategy 3 - Low Altitude Comparison Case for Option 1

    Strategy three is  the  comparison  case to strategy one.  With  five
    exceptions, the  strategy is  identical to strategy one.   The  five
    exceptions are as follows:

    1)  The  SEA  program   for  the  1984  and later model  year  LDTs
        requires a 40 percent  AQL  instead  of  a  10  percent  AQL regula-
        tion.

-------
    2)  The 1984 and later model  year HDV CO emission  standard  is  35
        gm/bhp-hr instead of 15.5 gm/bhp-hr.

    3)  There is no HDV 1984 or 1985 model year SEA program.

    4)  The SEA program for the  1986  and later model year  HDVs  has a
        40 percent AQL instead of a 10 percent AQL regulation.

    5)  The 1984 and  later  model year HDGVs  are assumed not  to need
        catalysts to achieve the emission standards.

These regulations  are summarized  in  Table 1  along with the revised
MOBILE2 emission rates used for strategy three.

4)  Strategy Four - Low Altitude Comparison Case For Option 2

    Strategy four is  the comparison to  strategy two.   With  two excep-
    tions, strategy  four  is identical  to strategy three.   These  two
    differences are those listed below:

    1)  The 1983  and later model  year  LDV CO  standard is  7.0  gm/mi
        instead of 3.4 gm/mi.

    2)  The  1983  and  later  model  year LDGV  technology  mix   is
        estimated to  be  5.3 percent  closed  loop throttle  body,  57.9
        percent  closed loop carbureted,  and  36.8  percent  open loop
        carbureted systems.

    These differences  are  summarized  in Table  1  along  with all  other
    revised MOBILE2 CO emission rates and regulations.

5)  Strategy Five - High Altitude Base Case

    In  strategy  five, the 1984+  LDTs are assumed  to be designed  to
    the proportional CO emission  standards while the  HDVs  are assumed
    to be low altitude vehicles operated at high altitude.

    The 1984  and later model  year LDTs  differ from MOBILE2  in that
    they reflect the  14 gm/mi  CO  emission (proportional) standard,  no
    specific  SEA program,  and a  full  useful  life definition.   The
    expected  technology  mix is  100  percent  oxidation catalyst  sys-
    tems.  No  threeway catalysts  are assumed  for  the high  altitude
    LDGTs.

    The CO emission  rates  for  the 1984  and   later  model  year HDVs
    reflect the  low  altitude  vehicles operated at  high altitude from
    strategies 1 and 2.

    The  revised MOBILE2  emission  rates  and   regulations   referenced
    above are given in Table 2.

-------
    6)  Strategy Six - High Altitude Comparison Case

        Strategy six  has two differences  from  strategy  five.  With  the
        exception of  these  two  differences,  described  below, all  other
        vehicle  type  emission  rates  and   regulations  are  identical  to
        those in strategy five.

        1)  The  low altitude SEA  program  for the 1984  and  later  model
            year LDTs  in strategies  3 and  4  requires a  40  percent  AQL
            instead of  a 10 percent  AQL  regulation.   This  is  assumed to
            affect the high altitude LDGT CO emission rates.

        2)  Although there are no specific  HDV high altitude regulations,
            HDGVs are assumed  to be  the  low altitude HDGVs,  from strat-
            egies 3 and 4, being operated at high altitude.

l.D  MOBILE2 Output

Table 3 through  8 present  the  MOBILE2 results for  all six runs performed
for  this  analysis  of revised CO  emission  standards  on  1984 and  later
model year  LDTs  and HDVs.  Table 3  presents the MOBILE2  results  for  the
existing  LDV,  LDT,  and  HDV low  altitude  regulations  -  strategy  one.
Table  4  gives  the strategy  two  results  from MOBILE2.   Strategy  two
reflects  the  current regulations  for LDTs  and  HDVs,  and assumes a  7.0
gm/mi CO standard on the  1983+ LDVs.   The  results  from MOBILE2 for strat-
egy three are given in  Table 5.  Strategy  three, which presents the emis-
sion  results  of the  proposed  LDT  and HDV  regulation  revisions,  is  the
comparison  case  to  strategy one.   The results  from MOBILE2  for  strategy
four  are  given in  Table  6.   Strategy four,  which presents  the  emission
results of  the  proposed  LDT and HDV regulation revisions,  is the  com-
parison case  to strategy two.   The  results  from  MOBILE2  for  strategy
five, the high altitude base case, are given  in Table 7.   Strategy  five
represents the current  set of high  altitude HDV, and proportional  LDT  and
LDV regulations.  Table 8 presents the MOBILE2  results for strategy  six,
the comparison case to strategy five.   Strategy six represents the  pro-
posed revisions  to  the LDT and HDV regulations.

The second  part  of this  report  presents the  assumptions  and  results  of
the air quality assessment.

2.  Air Quality Models

The modified  linear  rollback  model  (Rollback)  was used  to estimate  CO
ambient concentrations  in  the  future.  In Rollback, a proportional  rela-
tionship is assumed to  exist between the ambient concentration of a pol-
lutant  at  a monitoring  site and the total inventory of   that  pollutant
emitted in  the  vicinity  of  the site.   Thus,  if  emissions decline over
time, ambient  concentrations are assumed to decline  in  the  same  propor-
tion.  A detailed description of Rollback is contained  in reference [3].

-------
2.A Inventories

The National  Emission  Data  System  (NEDS)  provided  the basic  inventory
estimates for  the  urban areas  studied  in this analysis[4].   These areas
are listed in Table 9.  The  total  tonnage of  pollution emitted within the
counties  associated  with  these urban  areas  was  used as  the base  year
(1977) inventory.  NEDS provides estimates for  both mobile  and stationary
emission  sources.   However,  since  the  highway mobile source  portion  of
the current  (1977)  NEDS inventory  utilizes  March, 1978  emission  factors
(MOBILE1), this  portion of the inventory was  adjusted for the new emis-
sion factors contained  in  MOBILE2[5],   [2].   Stationary area  source emis-
sions were obtained directly from  NEDS.  Appendix  B contains  the  adjusted
inventory for  the 1977 base year  used in this  analysis.    The  appendix
also presents in graphical form the future inventory levels predicted for
the six scenarios considered for this report.

2.B Source Contribution Factors

A source  contribution factor is designed to  account  for  stack height and
distance  between an  emissions  source  and  the ambient  monitor.   Since
dispersion models  have  indicated  that  CO stationary point  source  emis-
sions  do  not  influence the ambient concentration  measurements  made  at
urban monitors,  those sources   are  assigned  a source  contribution  factor
of zero[6].  For the same reason  CO stationary area sources as well  as
off-highway mobile  sources  are assigned source  contribution  factors  of
0.20; that is, emissions from  those sources  are discounted to 20  percent
of  their  total  value.   Emissions  from  highway  mobile  sources  are  not
discounted.

2.C Design Values

Design values  are measured ambient air quality concentrations  from which
future concentrations are  predicted.   The ambient  concentration  measure-
ments are generally collected  by the states  and entered  into the  Storage
and  Retrieval  of  Aerometric  Data  (SAROAD)   system  maintained  by  EPA.
Design values are calculated from those data  in a manner that

conforms  to  the National  Ambient  Air  Quality Standard  (NAAQS)  for  the
pollutant and urban area under  study.   The design  values  for  CO are based
upon  the  second  maximum  non-overlapping 8-hour  concentrations  in  the
worst year of record.   For this analysis  the  worst year of record  in the
three year period of 1976-1978  was used.-'-
Rollback  only  requires  that  ambient pollutant  concentrations  be  known
for  the  same year  that  the emissions inventory  is estimated.  However,
design values are  generally estimated from  the worst year  of record  in
the  three  year  period  bracketing the base year inventory.   This approach
prevents Rollback from underestimating future concentration  levels in  the
presence of one  year of favorable meteorological conditions.

-------
2.D Background Levels

Background levels  refer  to natural  background ambient  pollutant  concen-
trations that are  the  result of  emissions  from natural sources,  such as
decaying vegetation, forest  fires,  and  lightning.  All man-made  sources
are specifically excluded  from this classification, even if  the man-made
pollution originating  from sources  outside of the  study area  is trans-
ported into  the area by repetitive  weather patterns.   Normally,  natural
background sources  of  CO  contribute a  negligible amount  to  the  ambient
concentrations  measured  at  urban monitoring  sites.   In  this  analysis,
natural background  levels  were assumed  to  be  zero.   This  is  in  keeping
with recent EPA guidance[7].

2.E Stationary Source Control

No control was assumed on  stationary sources  of CO emissions, since emis-
sions  from  these  sources  are  generally  attributed   to  space  heating
devices and the likelihood of controls being applied to them is low.

2.F Growth and Retirement Rates
The retirement rate  is  essentially a scrapage rate; that  is,  the  rate at
which  old  equipment is retired  and replaced  by  new equipment.   For the
purposes of this analysis,  a  zero retirement is assumed for CO stationary
area sources.

Growth  rates  express the  expected increase  in usage  associated with each
pollution  source.   Since  area CO sources are,  for the most  part,  space
heating  devices,  their usage rate has  been  assumed  to increase at the
expected 0.8  percent annual population growth  rate.

The  mobile source  growth rates  assumed to  apply in  this analysis  are
listed  in  Table  10.  The heavy duty  gasoline and  diesel  truck rates and
the  motorcycle  growth rate are  derived  directly  from  the  Methodology to
Conduct  Air  Quality  Assessments[6].    The   growth rate  of  non-highway
mobile  sources is an approximate  average of  the rates listed for separate
categories  in  that  publication.   The  light  duty  truck  and  passenger
vehicle  fleet growth rates were  derived from the data presented in the
"Automotive  Fuel Demand"  paper   [8]  using   the  methodology presented  in
Assessments reference.  The two  sets of  calculations  (Assessments versus
Table  10)  differ  only  in  that   the  Assessments  reference computes  an
annual  growth rate  based on the differences  in vehicle miles  traveled
(VMT)  estimates  between 1977  and  1990 whereas the rates listed  in  Table
10  are based on differences  between the longer  period  of 1977  to  1995.
The effect of this change is  to lower the annual compound growth rate.

2.H Summary of Results

The air  quality  impact  of the various control strategies  is evaluated in
terms  of three indicators.  These are as follows:

    1.  The  average percent  change  in  8-hour CO  concentrations  between
         1977 and the future years studied;

-------
                                   10
    2.  The estimated number of counties above  the  ambient  CO standard in
        the future;  and

    3.  The predicted number of exceedences of the ambient CO standard.

When  comparing  emission  control  strategies,  it is  generally better  to
focus on the aggregate differences  in these air quality indicators rather
than on the absolute numbers of predicted violations for each urban area.

The first section of Table  11  presents the average percent  change of the
expected 8-hour average ambient CO  concentrations  from 1977 levels in low
altitude, 49-state urban  areas.   The  first two  scenarios refer to a 15.5
gm/bhp-hr CO standard  for HDVs and SEA  programs for  HDVs  and  LDTs based
on  10%  AQL.   The comparison scenarios refer to a  35 gm/bhp-hr  CO level
for HDVs and  a  40% AQL  in SEA for HDVs  and LDTs.   All  scenarios assume
that inspection maintenance programs  are in place  by  January 1,  1982.  As.
indicated in Table  11, if  the 3.4 gm/mi  CO  LDV "low  standard"  strategy
prevails,  the  8-hour  average  ambient  CO  concentration levels will be 77
percent  lower  in 1995  than they were in  1977.   In  comparison,   the  3.4
gm/mi CO  LDV 'high  standard1  case is expected to exhibit a  75  percent
reduction in  the same time  frame.   The 7.0  gm/mi  CO LDV  "low standard"
strategy  is  expected  to  exhibit  a 74  percent reduction  in ambient  CO
concentrations in 1995.   The comparable 7.0  gm/mi  CO LDV "high standard"
case  will  have  a  72  percent  reduction in  ambient CO  concentrations  in
1995.  A smaller  improvement would also be expected  if  growth in vehicle
miles traveled is greater than forecast.
                            A
Table 11 also  provides the number  of  counties  expected  to  exceed  the .10
mg/nr 8-hour average  CO  NAAQS in  each projection  year.  All urban areas
are expected to  comply with the NAAQS by  1990  if any of the first three
strategies prevails.  If  the 7.0  gm/mi CO  LDV "high standard" is  adopted,
the date of compliance is somewhat later.   The  third  section of  Table 11
provides  the  total  number  of  NAAQS exceedences in each  projection year.
In  1987 these range from  three exceedences under the  3.4 gm/mi "low stan-
dard" case  to  seven exceedences  in the 7.0  gm/mi "high standard" case.
Finally, the last section of Table 11 shows  the total  tons  of CO emitted
for each low altitude strategy in each projection year.

Table 12 displays the  same information for the  two high  altitude scenar-
ios as Table 11  displays  for  the low  altitude,  49-state  scenarios.  Gen-
erally,  greater  improvement in  the air quality indicators  is shown  for
the base case than for the comparison  case.

The middle sections  of Tables  11 and  12 have been presented  to  show the
number  of  areas expected  to exceed  the  NAAQS  in  each  projection ye-ar.
These  tables  should  be  used  cautiously.   A  comparison of  differences
among scenarios is least  apt  to  be affected  by  changes  in  the underlying
analytical assumptions.   Statements about  the number  of  violations  or  the
number of urban areas  in  non-attainment  status  at  any particular  year are
more sensitive to changes in the basic assumptions.

       Alternate I/M Credits For The LDT-HDV Air Quality Analysis

Seven alternate  sets  of I/M credits  were generated  for  the LDT-HDV air
quality analysis.  The  seven  sets  were generated  for the 1981 and  later
model year light duty  gasoline powered vehicles.   Four  sets for the low
altitude and three sets  for  the  high altitude passenger cars.  Table A-l
presents a  summary of  the  seven alternate  sets.   This  table gives the
table number for each model year,  strategy,  and region for which the I/M
credits are valid.
