MODELING/
ANALYSIS
PROTOCOL
The
modeling/
analysis
protocol
serves
numerous
functions
including:
(
1)
identifying
the
local
(
lead)
air
quality
agency
assisting
the
State
with
attainment
analyses,
(
2)
identifying
methods
and
procedures
used
to
support
the
demonstration,
and
(
3)
describing
the
review
process
applied
to
steps
in
the
demonstration
process
(
EPA,
1999).
Although
the
protocol
serves
other
functions,
one
of
the
most
important
is
providing
a
means
of
planning
and
communicating
the
procedures
to
be
used
for
demonstrating
attainment.

Appendix
J
is
divided
into
two
parts.
The
first,
Protocol
Overview,
lists
key
issues
that
are
addressed
in
the
local
modeling/
analysis
protocol
and
describes
the
means
used
to
fulfill
protocol
requirements.
Part
two
of
this
appendix
consists
of
the
Modeling
Protocol
document
provided
to
AACOG
by
ENVIRON
International
Corporation
for
development
of
the
1999
photochemical
model.

PART
1:
PROTOCOL
OVERVIEW
Lead
Agency
The
local
(
or
lead),
agency
assists
the
State
with
evaluating
the
analyses
needed
to
support
a
defensible
demonstration.
For
purposes
of
the
SAER
attainment
demonstration,
the
lead
agency
is
the
Alamo
Area
Council
of
Governments
(
AACOG).
Although
AACOG
is
the
local
agency
charged
with
emissions
inventory
development,
photochemical
model
development,
and
other
major
components
of
the
SAER
attainment
demonstration,
the
agency
works
closely
with
the
state
(
Texas
Commission
on
Environmental
Quality)
and
federal
(
US
Environmental
Protection
Agency)
governments
to
ensure
compliance
with
applicable
guidance
and
regulations.

Stakeholders
Participating
in
the
Process
Local
stakeholders
participating
in
the
protocol
process
include
the
Air
Improvement
Resources
(
AIR)
Committee
of
the
Alamo
Area
Council
of
Governments.
Formed
in
April
1999,
the
mission
of
the
AIR
Committee
is
twofold:
(
1)
facilitate
the
completion
of
the
air
quality
studies
and
necessary
planning
activities
for
attainment
under
the
new
8­
hour
average
ozone
NAAQS,
and
(
2)
develop
a
comprehensive
emission
reduction
plan
that
will
guide
the
region's
actions
to
attain
the
8­
hour
NAAQS.
Furthermore,
much
of
the
technical
and
educational
air
quality
activities
conducted
by
AACOG
are
directed,
reviewed,
and
approved
by
the
AIR
Committee.
The
Air
Improvement
Resources
Committee
is
composed
of
five
subcommittees
as
described
below:

AIR
Executive
Committee
The
AIR
Executive
Committee
is
comprised
of
members
representing
the
major
government
organizations
within
the
San
Antonio
Metropolitan
Statistical
Area
defined
according
to
data
from
the
1999
U.
S.
Census.

The
following
municipal
and
county

At
the
time
the
Early
Action
Compact
was
signed,
the
MSA
consisted
of
four
counties:
Bexar,
Comal,
Guadalupe,
and
Wilson.
The
bylaws
of
the
AIR
Committee
state
that
"
membership
shall
be
extended
to
similar
local
governments
brought
into
the
San
Antonio
Metropolitan
Statistical
Area
through
US
Census
redesignations
of
the
SA/
MSA
boundary."
As
recently
as
December
2003,
EPA
Region
6
Administrator
Richard
Greene
affirmed
that
only
this
four­
county
region
is
recommended
as
the
nonattainment
area
for
the
San
Antonio
region.

Committee
is
charged
with
disseminating
information
about
the
ozone
challenge
through
news
media
and
public
events.
Its

Subcommittee
works
with
local
industry
to
promote
voluntary
implementation
of
ozone
control
strategies
and
studies
the
impact
of
legislation
and
other
legal
issues
on

off­
road
community.
The
Off­
Road
Subcommittee
membership
includes
owners/
operators
of
off­
road
equipment
in
the
public
and
private
sectors.

Alamo
Area
Clean
Cities
Coalition
Although
the
Alamo
Area
Clean
Cities
Coalition
is
not
a
subcommittee
of
the
AIR
Committee,
the
coalition
encourages
local
governments
and
organizations
to
form
public/
private
partnerships
to
develop
markets
for
alternative
fuel
vehicles
(
AFVs).
Clean
Cities
is
a
voluntary
federal
program
funded
by
the
U.
S.
Department
of
Energy
to
accelerate
and
expand
the
use
of
alternative
fuels
in
communities
throughout
the
country
and
to
develop
the
necessary
infrastructure
for
their
operation.

Since
1996,
the
AACOG
has
supported
the
Alamo
Area
Clean
Cities
Coalition
by
hosting
meetings,
organizing
awareness
events,
and
developing
project
subcommittees
that
are
chaired
by
members
of
the
local
community.
As
a
regional
planning
organization,
the
coalition
works
to
improve
the
quality
of
life
in
South­
central
Texas
including
the
12­
county
area
surrounding
the
City
of
San
Antonio.

Public
Participation
Each
meeting
of
each
of
the
subcommittees
of
the
Air
Improvement
Resources
Committee
system
is
open
to
the
public.
Although
the
AIR
Technical
Committee
is
a
technical
working
group
and
is
not
a
forum
for
policy
development
and
action,
the
agendas
of
the
regular
meetings
of
this
committee
have
always
included
a
"
Citizens
to
be
Heard"
item.
In
addition
to
a
"
Citizens
to
be
Heard"
item,
the
bylaws
of
the
AIR
Committee
system
allow
citizens
to
address
every
action
item
on
the
AIR
Executive/
Advisory
Committee
agendas,
guaranteeing
the
right
of
the
citizens
to
voice
their
opinion
prior
to
any
vote
by
the
policy
development
and
action
committee.

Management
/
Communication
Procedures
Many
of
the
technical
decisions
required
by
the
modeling/
analysis
protocol
 
such
as
episode
selection,
choice
of
photochemical
models,
and
others
 
were
first
discussed
and
evaluated
by
representatives
of
the
Texas
Near
Non­
attainment
Areas
(
NNAs),
the
Texas
Commission
on
Environmental
Quality,
the
Environmental
Protection
Agency,
and
other
technical
advisors
during
regularly­
scheduled
meetings
of
the
Texas
NNA
Working
Group.
A
list
of
participants
and
stakeholders
involved
in
the
process
is
provided
in
part
2
of
this
appendix.

For
instances
where
technical
decisions
affecting
the
San
Antonio
EAC
Region
(
SAER)
were
first
evaluated
and
approved
by
the
NNA
Working
Group,
approval
was
subsequently
sought
at
the
local
level.
Technical
decisions
reviewed/
approved
at
the
local
level
included
such
issues
as
episode
selection
and
performance
of
the
photochemical
model.
A
typical
process
involving
local
participation
would
start
with
review
and
approval
by
the
Texas
NNA
Working
Group
(
including
input
from
TCEQ
and
EPA)
followed
by
review
and
approval
by
the
AIR
Technical
Committee.
Upon
approval
by
the
Technical
Committee,
the
group
would
provide
recommendations
to
the
AIR
J­
8
Executive/
Advisory
Committee.
Final
decisions
were
made
by
vote
of
the
Executive
members
during
public
meetings
of
the
AIR
Executive/
Advisory
Committee.
Whenever
the
protocol
decisions
involved
matters
of
policy,
the
AIR
Executive
Committee
made
recommendations
for
action
to
the
local
governments
represented
by
the
AIR
Executive
Committee
membership.

For
decisions
such
as
modeling
of
potential
clean
air
strategies
and
selection
of
clean
air
strategies
for
adoption
in
the
SIP,
evaluation
and
approval
were
primarily
local
issues.
Input
regarding
potential
clean
air
strategies
was
sought
from
as
many
local
stakeholders
as
possible
including
members
of
the
AIR
Technical
Committee,
the
Alamo
Area
Clean
Cities
Coalition,
and
the
Off­
road
Equipment
Subcommittee.
Additionally,
public
input
was
encouraged
through
a
series
of
meetings
conducted
by
AACOG
that
addressed
such
topics
as
the
Clean
Air
Plan,
regional
air
quality,
and
clean
air
strategies
as
shown
in
table
J­
2.

AACOG
staff
provided
news
briefs
to
the
media
regarding
public
meetings
to
encourage
participation
as
shown
in
exhibit
A.
The
public
meetings
were
held
at
various
locations
and
in
all
four
SAER
counties
to
provide
access
to
as
many
regional
citizens
as
possible.
In
addition
to
citizen's
comments
made
during
public
meetings,
AACOG
encouraged
feedback
by
accepting
public
comments
via
mail,
fax,
and
email.
Public
comments
were
compiled
and
provided
to
the
AIR
Executive
Committee
(
voting)
members
on
a
regular
basis.

Choice
of
Air
Quality
Simulation
Model
and
how
it
Meets
Requirements
in
40CFR51,
Appendix
W
for
using
"
Alternative"
Models
The
September
1999
episode
was
modeled
by
ENVIRON
International
Corporation
using
the
Comprehensive
Air
Quality
Model
with
Extensions
(
CAMx).
In
2003,
the
federal
guidance
listing
alternative
models
(
appendix
B
of
40
CFR
Part
51,
appendix
W)
was
removed
from
appendix
W
(
Federal
Register,
2003)
and
placed
on
EPA's
Support
Center
for
Regulatory
Air
Models
(
SCRAM)
web
site.
This
web
site
lists
CAMx
as
an
alternative
dispersion
model
(
EPA
web
page,
no
date).

Rationale
for
Choice
of
Air
Quality
and
Emissions
Model
and
Choice
of
Method
for
Generating
Meteorological
Inputs
According
to
EPA's
Summary
Descriptions
of
Alternative
Air
Quality
Models
(
EPA
web
page,
no
date),
"
CAMx
is
appropriate
for
simulating
hourly
ozone,
CO,
and
PM
concentrations
from
the
urban­
scale
to
regional­
scale."
Furthermore,
the
Texas
Commission
on
Environmental
Quality
supports
the
use
of
CAMx
for
regional­
scale
modeling.
The
Attainment
Demonstration
for
the
Dallas/
Fort
Worth
Ozone
Nonattainment
Area
(
TNRCC,
1999)
states
that
models
recommended
by
the
EPA
in
past
years
had
been
replaced
with
updated
counterparts
such
as
CAMx
that
demonstrate
"
improved
model
chemistry,
better
treatment
of
vertical
diffusion,
and
more
realistic
treatment
of
plumes."
Because
of
these
and
other
advantages,
the
TCEQ
recommends
the
use
of
CAMx
for
ozone
attainment
demonstration
modeling
in
Texas.

Emissions
inputs
to
the
photochemical
model
were
developed
by
a
variety
of
agencies.
State
and
regional
emissions
for
the
base
year
(
1999)
and
projection
year
(
2007)
were
provided
to
AACOG
from
the
Commission;
therefore
the
state
and
regional
EI
data
have
undergone
review
and
approval
at
the
state
level.
For
some
categories
of
inputs,
such
as
regional
2007
EI,
the
data
were
also
federally
approved.
Local
area
and
off­
road
sources
were
developed
by
AACOG
staff
using
EPA
recommended
/
alternative
methodologies
or
using
EPA
software
models
(
e.
g.,
NONROAD).
Local
biogenic
and
point
source
data
were
provided
by
the
Commission.
With
few
exceptions,
the
Commission­
provided
point
emissions
were
used
as
model
input.
Examples
where
the
Commission's
data
were
not
used
included
data
developed
from
measurements
recorded
at
or
studies
conducted
for
specific
emission
point
sources
(
e.
g.
a
wastewater
treatment
plant
and
power
plants)
and
provided
to
staff
by
representatives
of
those
point
sources.
Appendices
D
and
F
provide
additional
information
regarding
methodologies/
models
used
to
develop
the
modeling
emission
inventories.

The
Fifth
Generation
Pennsylvania
State
University/
National
Center
for
Atmospheric
Research
(
PSU/
NCAR)
Mesoscale
Model
(
MM5)
was
utilized
by
ENVIRON
to
develop
hourly,
three­
dimensional
meteorological
input
fields
for
CAMx.
The
original
1999
episode
was
developed
using
MM5v3.4
(
version
3,
release
4).
During
the
model
refinement
process,
modelers
were
able
to
take
advantage
of
the
expanded
capabilities
of
the
recently
released
MM5v3.5.
The
fifth­
generation
Penn
State/
NCAR
Mesoscale
Model
is
the
primary
tool
for
providing
meteorological
input
for
EPA's
Models­
3/
Community
Multiscale
Air
Quality
(
CMAQ)
modeling
system.
EPA
recognizes
that
MM5
is
widely
used
for
providing
meteorological
characterizations
throughout
the
air
quality
modeling
community
(
EPA
web
page,
no
date).
Development
of
the
meteorological
inputs
is
