STATEMENT
OF
REASONS
The
Illinois
Environmental
Protection
Agency
(“Illinois
EPA”)
hereby
submits
this
Statement
of
Reasons
to
the
Illinois
Pollution
Control
Board
(“Board”)
pursuant
to
Sections
27
and
28
of
the
Environmental
Protection
Act
(“Act”)
(415
ILCS
5/27
and
28)
and
35
Ill.
Adm.
Code
102.202(b),
in
support
of
the
attached
proposed
amendments
to
existing
regulations.
Included
in
this
proposal
are
amendments
to
35
Iii.
Adm.
Code
Part
243
(“Part
243”),
which
update
the
existing
Part
to
incorporate
new
federal
air
quality
standards.
These
changes
include:
amending
Section
243.125
to
the
repeal
the
1-hour
ozone
standard
and
replace
it
with
the
8-hour
ozone
standard;
proposing
a
new
Section
243.120a
to
incorporate
the
new
particulate
matter
standard
(PM
2
.
5
);
and
updating
Section
243.108
to
include
the
new
incorporations
by
reference.
This
proposal
amends
the
most
recent
version
of
Part
243
as
found
on
the
Board’s
website.
I.
ILLINOIS
ENVIRONMENTAL
ROThTh1N
AGENCY
PROPOSAL
This
proposed
rulemaking
simply
updates
the
existing
regulation
and
is
a
result
of
new
National
Ambient
Air
Quality
Standards
(“NAAQS”)
adopted
by
the
United
States
Environmental
Protection
Agency
(“U.S.
EPA”).
Originally,
the
Subpart
at
issue
was
adopted
to
satisfy
Clean
Air
Act
(“CAA”)
requirements.
Recent
changes
by
the
U.S.
EPA
require
amendments
to
the
Illinois
rules
to
reflect
the
new
NAAQS
for
both
ozone
and
particulate
matter.
More
specifically,
the
amendments
reflect
thenew
8-hour
ozone
standard
and
the
revocation
of
the
1-hour
standard.
This
new
standard
is
set
forth
in
a
recent
posting
in
the
Federal
Register,
National
Ambient
Air
Quality
Standards
for
Ozone,
73
Fed.
Reg.
16436
(March
27,
2008).
The
ambient
air
quality
standard
for
ozone
is
0.07
5
ppm
daily
maximum
8-hour
concentration,
and
is
based
on
the
fourth-highest
daily
8-hour
value
recorded
during
a
calendar
year
and
measured
by
a
reference
or
equivalent
method
as
described
in
40
CFR
Part
50,
Section
50.1(2003)
and
the
newly
created
Interpretation
of
the
NAAQS
for
03,
40
CFR
Appendix
P,
73
Fed.
Reg.
16436
(March
27,
2008).
Concerning
particulate
matter,
several
recent
postings
in
the
Federal
Register
reflect
changes
to
theNAAQS
for
PM
10
and
PM
2
,
5
.
On
July
18,
1997,
a
Federal
Register
posting
at
62
Fed.
Reg.
38652
lowered
the
annual
arithmetic
mean
concentration
to
15
micrograms
per
cubic
meter.
More
recently,
in
The
National
Ambient
Air
Quality
Standards
for
Particulate
Matter,
73
Fed.
Reg.
61144
(October
17,
2006),
a
maximum
24-hour
concentration
of
35
micrograms
per
cubic
meter
was
established.
This
was
to
be
calculated
at
the
98th
percentile
value,
as
determined
by
40
CFR
Part
50,
Appendix
N.
The
posting
also
updated
Appendix
L
of
40
CFR
Part
50,
which
describes
the
reference
method
used
for
the
determination
of
fine
particulatematter
as
PM
2
.
5
in
the
atmosphere.
Appendix
N,
meanwhile,
was
further
updated
in
a
separate
posting,
Interpretation
of
the
National
Ambient
Air
Quality
Standards
for
PM
2
,
5
,
40
CFR
Part
50,
Appendix
N,
73
Fed.
Reg.
1497
(January
9,
2008).
Finally,
Section
243.107,
Reference
Conditions,
was
2
updated
to
reflect
that
PM
2
.
5
measurements
should
be
based
upon
the
actual
ambient
air
volume
measured
at
the
actual
temperature
and
pressure
at
themonitoring
site
during
the
measurement
period.
This
differs
from
the
other
air
quality
measurements
which
are
corrected
to
a
reference
temperature
of
25°
C,
and
to
a
reference
pressure
of
760
millimeters
of
mercury
(1013.2
millibars).
The
standard
for
PM
10
was
also
amended
by
the
Federal
Register
posting
of
October
17,
2006.
The
Federal
Register
posting
revoked
the
annual
PM
10
standard
which
had
been
calculated
as
the
annual
arithmetic
mean
concentration
of
50
micrograms
per
cubic
meter.
The
posting
left
the
daily
PM
10
standard
unchanged
at
a
maximum
24-hour
concentration
of
150
micrograms
per
cubic
meter,
not
to
be
exceeded
more
than
once
per
year.
The
posting
further
amended
Appendix
K
of
40
CFR
Part
50,
which
described
the
interpretation
of
the
NAAQS
for
particulate
matter.
Lastly,
the
Illinois
EPA’s
proposal
involves
several
minor
corrections
to
Section
243.101
(Definitions),
Section
243.104
(Nondegradation),
Section
243.122
(Sulfur
Oxides
(Sulfur
Dioxide)),
and
Section
243.126
(Lead).
These
amendments
simply
correct
typographical
errors
and
put
citations
in
proper
form.
II.
GEOGRAPHIC
REGIONS
AND
SOURCES
AFFECTED
Sources
throughout
the
state
could
be
affected
by
this
proposal,
but,
as
stated,
the
proposal
simply
incorporates
the
addition
of
new
federal
standards
which
are
currently
applicable
throughout
the
nation.
III.
PURPOSE
AND
EFFECT
OF
THE
PROPOSAL
3
This proposal
is
a minor
clean-up
of
Part
243.
It
incorporates
new
U.S.
EPA
air
quality
standards
and
has
no
real
impact
upon
sources
as
it
is
currently
federal
law.
These
standards
are
well
known
to
industry
and
have
been
thoroughly
discussed
by
the
U.S.
EPA.
IV.
TECHNICAL
FEASIBILITY
AND
ECONOMIC
REASONABLENESS
The
amendments
to
Part
243
do
not
impose
new
requirements,
they
merely
update
the
State’s
regulations
to
reflect
current
federal
law
and
standards.
The
Illinois
EPA
therefore
believes
that
an
analysis
of
technical
feasibility
and
economic
reasonableness
is
not
appropriate.
These
standards
are
well
known
to
industry
and
have
been
thoroughly
discussed
by
the
U.S.
EPA.
V. COMMUNICATION
WITH
INTERESTED
PARTIES
These
amendments
are
being
proposed
based
on
current
national
ambient
air
quality
standards
adopted
by
the
U.S.
EPA
that
must
be
reflected
in
Illinois’
regulations.
As
the
changes
are
commonly
known
throughout
industry,
no
specific
program
of
outreach
was
implemented.
VI.
CONCLUSION
V9)
A
npos
a
rleanup
of
the
rule
at

Code

to

provisions
and
to

national
ambient

Section

Preamble
a)
Air
quality
Standards
are
limits
on
atmospheric
concentrations
of
air
contaminants
established
for
the
purpose
of
protecting
public
health
and
welfare.
The
levels
of
air
quality
designated
by
the
standards
are
designed
to
protect
against
injury
to
human,
plant
or
animal
life
and
they
are
further
intended
to
allow
maximum
enjoyment
of
life
and
property
consistent
with
the
intent
of
the
Act.
b)
The
first
use
of
our
air
resources
is
to
sustain
life.
Air
entering
the
respiratory
tract
must
not
menace
health.
Therefore,
the
air
quality
standards
set
must,
as
a
minimum,
provide
air
which
will
not
adversely
affect,
through
acute
or
chronic
symptoms,
the
health
of
the
community.
Adverse
health
effects
include
not
only
the
possible
production
and
aggravation
of
disease,
but
also
interference
with
bodily
functions.
The
standards
have
also
taken
into
account
soiling,
corrosion,
vegetation
damage
and
other
human
effects.
c)
Primary
ambient
air
quality
standards
define
levels
of
air
quality
which
are
necessary,
with
an
adequate
margin
of
safety,
to
protect
the
public
health.
Secondary
ambient
air
quality
standards
define
levels
of
air
quality
which
are
necessary
to
protect
the
public
welfare
from
any
known
or
anticipated
adverse
effects
of
a
pollutant.

d)
The
standards
are

Technical
Support

to
Part
243:
Air
Quality
Standards
Purpose
The
Clean
Air
Act
(CAA)
requires
that
the
U.S.
Environmental
Protection
Agency
(U.S.
EPA)
establish
National
Ambient
Air
Quality
Standards
(NAAQS)
for
six
criteria
pollutants
that
have
been
deemed
harmful
to
public
health
and
the
environment.
The
six
criteria
pollutants
are
ozone,
particulate
matter,
sulfur
dioxide,
nitrogen
dioxide,
carbon
monoxide,
and
lead.
The
CAA
also
requires
that
U.S.
EPA
review,
on
a
periodic
basis,
new
scientific
evidence
about
the
effects
of
these
pollutants
on
public
health
and
welfare
and
to
revise
the
standards
as
appropriate.
On
October
17,
2006
(effective
December
18,
2006),
U.S.
EPA
revised
the
NAAQS
for
particulate
matter,
reducing
the
24-hour
standard
for
fine
particles
less
than
2.5
microns
in
diameter
(PM
25
)
from
65
micrograms
per
cubic
meter
to
35
micrograms
per
cubic
meter.
On
March
12,
2008,
U.S.
EPA
also
strengthened
the
NAAQS
for
ozone,
reducing
the
8-hour
average
standard
from
0.08
parts
per
million
to
0.075
parts
per
million.
The
Illinois
Environmental
Protection
Agency
(Illinois
EPA)
is
proposing
to
amend
Part
243
of
Title
35
of
the
Illinois
Administrative
Code
to
update
Illinois’
air
quality
standards
consistent
with
those
adopted
by
the
U.S.
EPA.
The
Illinois
EPA
is
also
proposing
to
amend
Part
243
to
establish
an
annual
PM
2
.
5
standard
of
15
micrograms
per
cubic
meter,
consistent
with
the
Federal
standard
established
on
July
18,
1997,
and
to
revoke
the
annual
standard
of
50
micrograms
per
cubic
meter
for
PM
10
(particulate
matter
less
than
10
microns
in
diameter),
consistent
with
the
Federal
standards
as
revised
on
October
17,
2006.
Background
The
CAA
established
two
types
of
national
air
quality
standards:
primary
standards
and
secondary
standards.
Primary
standards
are
limits
for
protecting
public
health,
including
the
health
of
“sensitive”
populations
(such
as
asthmatics,
children,
and
the
elderly).
Secondary
standards
establish
limits
to
protect
the
welfare
of
thepublic,
which
includes
protection
against
decreased
visibility,
damage
to
buildings,
crops,
animals
and
vegetation.
As
mentioned
previously,
the
CAA
established
air
quality
standards
for
six
criteria
pollutants:
ozone,
particulate
matter,
sulfur
dioxide,
nitrogen
dioxide,
carbon
monoxide,
and
lead.
The
proposed
revisions
to
Part
243
address
the
recent
revisions
by
U.S.
EPA
of
the
national
air
quality
for
ozone
and
particulate
matter.
Ozone,
as
it
exi
ai
iuun
ievei
in
iosphere,
has
been
linked
to
health
effects
associated
with
the
lungs
and
respiratory
systems.
Speciflc:.
t
‘an
cause
reduced
lung
function,
irritated
airways,
a
higher
frequency
of
asthma
attacks,
inflammation
allu
:g
the
lining
of
the
lungs,
and
a
higher
risk
of
respiratory
infections.
This
can
result
in
greater
medication
us,
absences
from
school,
and
more
frequent
doctor
visits.
In
addition,
ground-level
ozone
can
have
detrimental
effects
on
public
welfare.
Elevated
ozone
levels
can
decrease
forest
growth
and
crop
yields,
greatly
damage
the
leaves
of
trees
and
other
plants
(which
would
ruin
the
appearance
of
1
urban
vegetation,
national
parks,
and
recreation
areas),
and
increase
the
susceptibility
of
sensitive
plants
to
diseases,
insects,
other
pollutants,
and
severe
weather.
Ozone
is
not emitted
into
the
ambient
air,
but rather
is
produced
in
the
atmosphere
through
a
complex
series
of
chemical
reactions
involving
nitrogen
oxides
(NOX)
and volatile
organic
material
(VOM)
emitted
by
both man-made
and
natural
emission
sources.
Significant
sources
of
NO
and
VOM
include
a
range
of
industrial
processes,
motorized
vehicles
(both
on-
and
off-
road),
and
the
use of
chemical
solvents.
Particulate
matter
(PM)
is
a
complex
mixture
of
particles
and
liquid
droplets
that
are
suspended
in
the
atmosphere.
Exposure
to
such
matter
has
been
linked
to
several
significant
health
problems.
Short-term
exposure
to
particulate
matter
(in hours
or
days)
can aggravate
the
lungs
and
cause
asthma
attacks,
acute
bronchitis,
and
could
even
raise
the
risk
of
respiratory
infections,
heart
attacks,
and
heart
arrhythmias.
Other
symptoms
include
irritation
of
the
eyes,
nose,
and
throat,
shortness
of
breath,
and
chest
pains.
Long-term
exposure
to
high
particulate
levels
can
lead
to
the
development
of
chronic
bronchitis
and
reduced
lung
function,
and premature
death
from
heart
and
lung
disease.
Welfare
effects
include
reduced
visibility
and
soiling
of
property.
Particulate
matter
is
emitted
from
a
wide
range
of
emission
sources,
include
fuel
combustion,
high
temperature
industrial
processes,
tire
and
brake
wear,
and
resuspension
of
dust
from
roads
and
farm
fields.
Particulate
matter
can
also
be
the
result
of
chemical
reactions
occurring
in
the
atmosphere,
involving
gaseous
pollutants,
such
as
sulfur
dioxide,
nitrogen
oxides,
ammonia,
and
organic
compounds.
U.S. EPA
has
established
NAAQS
for
two
categories
of
particulate
matter
based
on
the
size
of
the
particles.
Coarse
particulate
matter,
also
known
as
PM
10
,
is
defined
as
particles
that
are
less
than
10
micrometers
in
diameter.
The
PM
10
NAAQS
were originally
established
in
1987.
However,
effective
December
17,
2006,
U.S.
EPA
revoked
the
annual
standard
for
PM
10
as
more
recent
health
studies
attributed
adverse
long
term
health
effects
to
fine
particulate
matter
(PM
25
).
U.S. EPA
has
retained
the
existing
24-hour
PM
10
standard
of
150
micrometers.
li
1997,
U.S.
EPA
established
the
fine
particulate
matter
standard,
or
PM
25
,
to
address
the
adverse
health
impacts
associated
with
fine
particles
that
were
not
adequately
controlled
by
the
previous
PM
10
standards.
On October
17,
2006,
U.S. EPA
strengthened
the
24-hour
fine particle
standard
based
on
continuing
research
on
health
effects
of
particulate
matter.
Implementation
of
Revised
Air
Quality
Standards
Following
promulgation
of
a
new
or
revised
air
quality
standard,
the
CAA
requires
the
Governor
of
each
state
to
recommend
initial
designations
of
the
attainment
status
for all
areas
in
the
state.
Areas
can be
classified
as
nonattainment
(does
not
meet,
or
contributes
to
a
nearby
area
that
does
not
meet the
NAAQS),
attainment
(meets
the
NAAQS),
or
unclassifiable
(cannot
be
classified
based
on
available
data).
If
a
state
identifies,
through
ambient
monitoring,
that
an
area
fails
to
meet
the
NAAQS,
the
CAA
requires
a
state
with
areas
that
fail
to
meet
the
NAAQS
to
develop
a State
Implementation
Plan
2
(SIP)
describing
how
the
state
will
attain
and
maintain
the
NAAQS.
SIPs
must
include
control
strategies
or
measures
to
reduce
emissions
of
the
criteria
pollutant,
or
its
precursors,
as
needed
to
attain
the
standards
within
timeframes
prescribed
by
the
CAA.
Also, the
SiP
must
include
a
program
to
enforce
the
measures
specified.
The
state
adopts
the
SIP
only
after
reasonable
notice
and
public
involvement,
such
as
a
publichearing.
The
SIP is
then sent
to
U.S.
EPA
for
approval
or
disapproval.
Subsequent
to
the
1997
NAAQS
revisions,
the
counties
of
Cook,
DuPage,
Kane,
Lake,
McHenry,
Will,
and
Aux
Sable
and
Goose
Lake
Townships
in
Grundy
County,
and
Oswego
Township
in
Kendall
County
in
the
Chicago
area
have
been
designated
as
nonattainment
for
both
the
ozone
and
PM
2
.
5
standards.
In
the
Metro-East
area,
the
counties
of
Madison,
Monroe,
St.
Clair,
and
Jersey
have
been
designated
as
nonattainment
for
the
ozone
standard,
and
the
counties
of
Madison,
Monroe,
St.
Clair,
and
Baldwin
Township
in
Randolph
County
are
designated
as
nonattainment
for
PM
2
.
5
.
The
Illinois
EPA
is
still
in
the
process
of
developing
Illinois’
SIP
to
ensure
attainment
and
maintenance
of
the
NAAQS
established
in
1997.
Nonattainment
area
boundaries
have
not
yet
been
established
pursuant
to
the
2006
and
2008
NAAQS
revisions,
but
based
on
ambient
monitoring
data,
it
is
expected
that
the
same
areas
listed
above
will
be
designated
as
nonattairiment
for
one
or
both
of
the
standards.
The
Illinois
EPA
considers
the
technical
feasibility
and
cost
effectiveness
of
emission
controls
before
control
measures
are
included
in
the
SIP.
Specific
control
measures must
be
adopted
by
the
Illinois
Pollution
Control
Board
through
a
State
process
that
provides
for
the
consideration
of
alternate
measures
through
a
public
process.
Although
the
control
measures
adopted
through
the
SIP process
may invoke
significant
costs
on
emission
sources,
it
is
important
to
note
that
the
proposed
revisions
to
Part
243
do
not
impose
new
requirements
or
impose
new
costs
to
the
regulated
community.
