National
Emission
Standards
for
Hazardous
Air
Pollutants
for
Primary
Magnesium
Refining
AGENCY:
Environmental
Protection
Agency
(
EPA).
ACTION:
Proposed
rule.

SUMMARY:
This
action
proposes
national
emission
standards
for
hazardous
air
pollutants
(
NESHAP)
for
primary
magnesium
refining
facilities.
The
EPA
has
identified
primary
magnesium
refining
facilities
as
a
major
source
of
hazardous
air
pollutant
(
HAP)
emissions.
These
proposed
standards
will
implement
section
112(
d)
of
the
Clean
Air
Act
(
CAA)
by
requiring
all
major
sources
to
meet
HAP
emission
standards
reflecting
application
of
the
maximum
achievable
control
technology
(
MACT).
The
HAP
emitted
by
facilities
in
the
primary
magnesium
refining
source
category
include
chlorine,
hydrochloric
acid,
dioxin/
furan,
and
trace
amounts
of
several
HAP
metals.
Exposure
to
these
substances
has
been
demonstrated
to
cause
adverse
health
effects,
including
chronic
and
acute
disorders
of
the
blood,
heart,
kidneys,
reproductive
system,
and
central
nervous
system.
Some
of
these
pollutants
are
considered
to
be
carcinogens,
and
all
can
cause
toxic
effects
in
humans
following
sufficient
exposure.
DATES:

CAA
requires
the
NESHAP
to
reflect
the
maximum
degree
of
reduction
in
emissions
of
HAP
that
is
achievable.
This
level
of
control
is
commonly
referred
to
as
the
MACT.
The
MACT
floor
is
the
minimum
level
allowed
for
NESHAP
and
is
defined
under
section
112
(
d)(
3)
of
the
CAA.
In
essence,
the
MACT
floor
ensures
that
the
standard
is
set
at
a
level
that
assures
that
all
major
sources
achieve
the
level
of
control
at
least
as
stringent
as
that
already
achieved
by
the
bettercontrolled
and
lower­
emitting
sources
in
each
source
category
or
subcategory.
For
new
sources,
the
MACT
floor
cannot
be
less
stringent
than
the
emissions
control
that
is
achieved
in
practice
by
the
best­
controlled
similar
source.
The
MACT
standards
for
existing
sources
cannot
be
less
stringent
than
the
average
emission
limitation
achieved
by
the
best­
performing
12
percent
of
existing
sources
(
for
which
we
have
emissions
information)
in
the
category
or
subcategory
or
by
the
best­
performing
five
sources
(
for
which
we
have
or
could
reasonably
obtain
emissions
information)
for
categories
or
subcategories
with
fewer
than
30
sources.
In
developing
MACT,
we
also
consider
control
options
that
are
more
stringent
than
the
floor.
We
may
establish
standards
more
stringent
than
the
floor
based
on
the
consideration
of
cost
of
achieving
the
emissions
reductions,
nonair
quality
health
and
environmental
impacts,
and
energy
impacts.

C.
What
Source
Category
Is
Affected
by
the
Proposed
Rule?
Section
112(
c)
of
the
CAA
requires
us
to
list
all
categories
of
major
and
area
sources
of
HAP
for
which
we
will
develop
national
emission
standards.
We
published
the
initial
list
of
source
categories
on
July
16,
1992
(
57
FR
31576).
``
Primary
Magnesium
Refining''
is
one
of
the
source
categories
on
the
initial
list.
The
listing
was
based
on
our
determination
that
primary
magnesium
refining
facilities
may
reasonably
be
anticipated
to
emit
a
variety
of
HAP
listed
in
section
112(
b)
in
quantities
sufficient
to
be
major
sources.
The
source
category
is
comprised
of
one
plant,
US
Magnesium
Corporation
located
in
Rowley,
Utah.
The
plant
produces
magnesium
from
brine
(
salt
water)
taken
from
the
Great
Salt
Lake.
The
production
process
concentrates
the
magnesium
salts
in
the
brine,
then
processes
the
brine
to
remove
impurities
that
would
affect
metal
quality.
After
the
brine
solution
is
converted
to
a
powder
mixture
of
magnesium
chloride
(
MgCl2)
and
magnesium
oxide
in
the
spray
dryers,
the
powder
is
conveyed
to
the
melt/
reactors.
The
melt/
reactors
melt
the
powder
mixture
and
convert
the
remaining
magnesium
oxide
to
magnesium
chloride
by
injecting
chlorine
into
the
molten
salt.
The
purified
molten
salt
is
then
transferred
to
the
electrolytic
cells
where
the
molten
magnesium
chloride
salt
is
separated
into
magnesium
metal
and
chlorine
by
electrolysis.
The
electrolysis
process
passes
a
direct
electric
current
through
the
molten
magnesium
chloride,
causing
the
dissociation
of
the
salt
and
results
in
the
generation
of
chlorine
gas
and
magnesium
metal.
The
magnesium
metal
is
then
transferred
to
the
foundry
for
casting
into
ingots
for
sale.
The
chlorine
produced
is
piped
to
a
chlorine
plant
where
it
is
liquefied
for
reuse
or
sale.
The
HAP
emitted
from
the
primary
magnesium
refining
process
are
chlorine,
hydrochloric
acid,
dioxin/
furan,
and
trace
amounts
of
HAP
metals.
Emission
controls
include
various
combinations
of
wet
scrubbers
(
venturi
and
packed­
bed)
for
acid
gas
and
particulate
matter
(
PM)
control.
Chlorine
is
emitted
from
the
melting
and
purification
of
reactor
cell
product
and
is
controlled
by
conversion
to
hydrochloric
acid
in
the
chlorine
reduction
burner
and
subsequent
absorption
of
the
hydrochloric
acid
in
venturi
and
packed­
bed
scrubber.
Using
these
control
technologies,
upwards
of
99.9
percent
control
of
chlorine
is
achieved.
The
electrowinning
of
the
melted
magnesium
chloride
to
magnesium
metal
produces
as
a
byproduct
chlorine
gas
which
is
recovered
at
the
chlorine
plant.
When
the
chlorine
plant
is
inoperable,
the
chlorine
produced
at
the
electrolytic
cells
is
routed
to
a
series
of
packed­
bed
scrubbers
which
use
ferrous
chloride
as
the
adsorbing
medium.
Hydrochloric
acid
is
emitted
from
the
spray
drying
and
storage
of
magnesium
chloride
powder
and
the
melting
and
purification
of
reactor
cell
product
prior
to
the
electrowinning
process.
Hydrochloric
acid
emissions
are
controlled
by
venturi
and
packed­
bed
scrubbers.
Dioxin/
furan
are
generated
in
the
melt
reactor
and
are
subject
to
incidental
control
by
the
chlorine
reduction
burner
and
wet
scrubbers
used
to
control
chlorine,
hydrochloric
acid
(
HCl),
and
PM.

D.
What
Are
the
Health
Effects
Associated
With
Emissions
From
Primary
Magnesium
Refiners?
Acute
(
short­
term)
exposure
to
high
levels
of
chlorine
in
humans
can
result
in
chest
pain,
vomiting,
toxic
pneumonitis,
and
pulmonary
edema.
At
lower
levels,
chlorine
is
a
potent
irritant
to
the
eyes,
the
upper
respiratory
tract,
and
lungs.
Chronic
long­
term
exposure
to
chlorine
gas
in
workers
has
resulted
in
respiratory
effects
including
eye
and
throat
irritation
and
airflow
obstruction.
Animal
studies
have
reported
decreased
body
weight
gain,
eye
and
nose
irritation,
non­
neoplastic
nasal
lesions,
and
respiratory
epithelial
hyperplasia
from
chronic
inhalation
exposure
to
chlorine.
No
information
is
available
on
the
carcinogenic
effects
of
chlorine
in
humans
from
inhalation
exposure.
We
have
not
classified
chlorine
for
potential
carcinogenicity.
Hydrochloric
acid
is
corrosive
to
the
eyes,
skin,
and
mucous
membranes.
Acute
inhalation
exposure
may
cause
eye,
nose
and
respiratory
tract
irritation
and
inflammation
and
pulmonary
edema
in
humans.
Chronic
occupational
exposure
to
HCl
has
been
reported
to
cause
gastritis,
bronchitis,
and
dermatitis
in
workers.
Prolonged
exposure
to
low
concentrations
may
cause
dental
discoloration
and
erosion.
No
information
is
available
on
the
reproductive
or
developmental
effects
of
hydrochloric
acid
to
humans.
In
rats
exposed
to
hydrochloric
acid
by
inhalation,
altered
estrus
cycles
have
been
reported
in
females
and
increased
fetal
mortality
and
decreased
fetal
weight
have
been
reported
in
offspring.
We
have
not
classified
hydrochloric
acid
for
carcinogenicity.
There
are
a
variety
of
metal
HAP
contained
in
the
PM
emitted
from
the
primary
magnesium
refining
process.
The
principal
HAP
metals
emitted
include
trace
quantities
of
phosphorous
and
manganese.
Health
effects
in
humans
have
been
associated
with
both
deficiencies
and
excess
intakes
of
manganese.
Chronic
exposure
to
low
levels
of
manganese
in
the
diet
is
considered
to
be
nutritionally
essential
in
humans,
with
a
recommended
daily
allowance
of
2
to
5
milligrams
per
day.

high
levels
of

results
primarily
in
central
nervous
system
effects.
Visual
reaction
time,
hand
steadiness,
and
eye­
hand
coordination
were
affected
in
chronically­
exposed
workers.
Manganism,
characterized
by
feelings
of
weakness
and
lethargy,
tremors,
a
masklike
face,
and
psychological
disturbances,
may
result
from
chronic
exposure
to
higher
levels.
Impotence
and
loss
of
libido
have
been
noted
in
male
workers
afflicted
with
manganism
attributed
to
inhalation
exposures.
We
have
classified
manganese
in
Group
D,
not
classifiable
as
to
carcinogenicity
in
humans.
Organic
HAP
such
as
chlorinated
dibenzodioxins
and
furans
(
CDD/
F)
have
been
detected
in
the
melt/
reactor
exhaust.
One
CDD/
F
compound,
2,3,7,8­
tetrachlorodibenzo­
p­
dioxin
(
2,3,7,8­
TCDD),
commonly
called
dioxin)
is
listed
singly
as
a
HAP.
Other
CDD/
F
compounds,
many
of
which
cause
adverse
health
effects
in
the
same
way
as
dioxin,
are
HAP
under
the
definition
of
polycyclic
organic
matter.
Exposure
to
CDD/
F
mixtures
causes
chloracne,
a
severe
acne­
like
condition
and
has
been
shown
to
be
extremely
toxic
in
animal
studies.
Dioxin
is
known
to
be
a
developmental
toxicant
in
animals
causing
skeletal
deformities,
kidney
defects,
and
weakened
immune
responses
in
the
offspring
of
animals
exposed
during
pregnancy.
Human
studies
have
shown
an
association
between
dioxin
and
soft­
tissue
sarcomas,
lymphomas,
and
stomach
carcinomas.
We
have
classified
dioxin
as
a
probable
human
carcinogen
(
Group
B2).
In
addition
to
HAP,
the
proposed
rule
would
also
reduce
particulate
matter
emissions
which
are
controlled
under
national
ambient
air
quality
standards.
Brief
exposure
to
particulate
matter
has
caused
aggravation
of
existing
respiratory
and
cardiovascular
disease
and
increased
risk
of
premature
death.
We
recognize
that
the
degree
of
adverse
effects
to
health
experienced
by
exposed
individuals
can
range
from
mild
to
severe.
The
extent
and
degree
to
which
the
health
effects
may
be
experienced
depends
on:
 
Pollutant­
specific
characteristics
(
e.
g.,
toxicity,
half­
life
in
the
environment,
bioaccumulation,
and
persistence);
 
The
ambient
concentrations
observed
in
the
area
(
e.
g.,
as
influenced
by
emission
rates,
meteorological
conditions,
and
terrain);
 
The
frequency
and
duration
of
exposures;
and
 
Characteristics
of
exposed
individuals
(
e.
g.,
genetics,
age,
preexisting
health
conditions,
and
lifestyle),
which
vary
significantly
with
the
population.

II.
Summary
of
Proposed
Rule
A.
What
Are
the
Affected
Sources
and
Emission
Points?
The
affected
source
is
each
new
or
existing
primary
magnesium
refinery.
A
new
affected
source
is
one
constructed
or
reconstructed
after
January
22,
2003.
An
existing
affected
source
is
one
constructed
or
reconstructed
on
or
before
January
22,
2003.
The
proposed
rule
covers
emissions
from
spray
dryers,
the
melt
reactor
system,
the
launder
off
gas
system,
and
magnesium
chloride
storage
bins.

B.
What
Are
the
Compliance
Deadlines?

The
owner
or
operator
of
an
existing
affected
source
would
have
to
comply
by
[
DATE
12
MONTHS
AFTER
THE
FINAL
RULE
IS
PUBLISHED
IN
THE
Federal
Register].
New
or
reconstructed
sources
that
startup
on
or
before
[
DATE
THE
FINAL
RULE
IS
PUBLISHED
IN
THE
Federal
Register]
must
comply
by
[
DATE
THE
FINAL
RULE
IS
PUBLISHED
IN
THE
Federal
Register].
New
or
reconstructed
sources
that
startup
after
[
DATE
THE
FINAL
RULE
IS
PUBLISHED
IN
THE
Federal
Register]
must
comply
upon
initial
startup.

C.
What
Are
the
Emission
Limitations?

The
proposed
rule
includes
mass
rate
emission
limits
in
pounds
per
hour
(
lbs/
hr)
for
chlorine,
hydrochloric
acid,
PM,
and
PM10.
The
emission
limits
are
shown
in
Table

of
this
preamble.

The
proposed
rule
also
includes
emission
limits
for
dioxin/
furan
expressed
in
nanograms
of
toxicity
equivalents
per
dry
standard
cubic
meter
(
ng
TEQ/
dscm)
corrected
to
7
percent
oxygen.
Dioxins/
furans
include
a
group
of
17
chemicals
or
congeners
that
share
certain
similar
chemical
structures
and
biological
characteristics.
The
2,
3,
7,
8­
tetrachlorodibenzo­
pdioxin
congener
is
the
most
well
studied
and
the
most
toxic
of
these
compounds.
Scientists
believe
that
dioxins
cause
effects
in
similar
ways.
Because
of
this
and
because
exposure
is
typically
to
variable
mixtures
of
dioxinlike
compounds,
we
use
toxicity
equivalency
factors
(
TEF)
that
compare
the
potential
toxicity
of
each
of
the
individual
dioxin­
like
compounds
to
the
relative
toxicity
of
2,
3,
7,
8­
tetrachlorodibenzo­
p­
dioxin.
With
such
factors,
the
toxicity
for
a
mixture
can
be
expressed
in
terms
of
its
Toxicity
Equivalents
(
TEQ),
which
is
the
amount
of
TCDD
it
would
take
to
equal
the
combined
toxic
effect
of
all
the
dioxinlike
compounds
found
in
the
mixture.
To
calculate
the
TEQ,
the
concentration
of
each
dioxin­
like
compound
is
multiplied
by
its
respective
TEF.

D.
What
Are
the
Operation
and
Maintenance
Requirements?

All
plants
subject
to
the
proposed
rule
would
be
required
to
prepare
and
implement
a
written
startup,
shutdown,
and
malfunction
plan
according
to
the
requirements
in
§
63.6(
e)
of
the
NESHAP
General
Provisions.
All
plants
must
establish
and
meet
operating
limits
for
pressure
drop
and
scrubber
water
flow
rate.
A
written
operation
and
maintenance
plan
is
also
required
for
control
devices
subject
to
an
operating
limit.
The
plan
must
describe
procedures
for
monthly
inspections
and
preventative
maintenance
requirements
for
control
devices.

E.
What
Are
the
Initial
Compliance
Requirements?

The
proposed
rule
requires
a
performance
test
for
each
control
device

Proposed
Rules
to
demonstrate
initial
compliance
with
the
applicable
emission
limits
of
chlorine,
hydrochloric
acid,
PM,
PM10,
and
dioxin/
furan.
The
EPA
Method
26
or
26A
in
40
CFR
part
60,
appendix
A
is
the
reference
method
for
chlorine
and
hydrochloric
acid.
The
reference
method
for
PM
is
EPA
Method
5
or
5D
in
40
CFR
part
60,
appendix
A.
The
reference
method
for
PM10
is
EPA
Method
201
in
40
CFR
part
60,
appendix
A.
The
EPA
Method
23
of
40
CFR
part
60,
appendix
A
is
the
reference
method
for
dioxin/
furan.
The
proposed
rule
would
also
require
owners/
operators
to
establish
operating
limits
for
scrubber
pressure
drop
and
scrubber
water
flow
rate
concurrent
with
the
performance
of
the
initial
compliance
tests.

F.
What
Are
the
Continuous
Compliance
Requirements?
The
proposed
rule
would
require
primary
magnesium
refineries
to
conduct
performance
tests
at
least
twice
during
each
title
V
operating
permit
term
(
at
midterm
and
renewal)
to
demonstrate
continuous
compliance
with
the
emission
limits.
Plants
would
also
be
required
to
monitor
operating
parameters
for
control
devices
subject
to
operating
limits
and
carry
out
the
procedures
in
their
operation
and
maintenance
plan.
For
wet
scrubbers,
plants
would
be
required
to
use
continuous
parameter
monitoring
systems
(
CPMS)
to
measure
and
record
the
hourly
average
pressure
drop
and
scrubber
water
flow
rate.
To
demonstrate
continuous
compliance,
plants
would
keep
records
documenting
conformance
with
the
monitoring
requirements
and
the
installation,
operation,
and
maintenance
requirements
for
CPMS.

G.
What
Are
the
Notification,
Recordkeeping,
and
Reporting
Requirements?
We
selected
the
proposed
notification,
recordkeeping,
and
reporting
requirements
to
be
consistent
with
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A).
One­
time
notifications
are
required
by
EPA
to
know
what
facilities
are
subject
to
the
standards,
if
a
facility
has
complied
with
the
proposed
rule
requirements,
and
when
certain
events
such
as
performance
tests
and
performance
evaluations
are
scheduled.
Semiannual
compliance
reports
containing
information
on
any
deviation
from
the
proposed
rule
requirements
are
also
required.
These
reports
would
include
information
on
any
deviation
that
occurred
during
the
reporting
period;
if
no
deviation
occurred,
only
summary
information
would
be
required.
Consistent
with
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
we
also
require
an
immediate
report
of
any
startup,
shutdown,
or
malfunction
where
the
actions
taken
in
response
were
not
consistent
with
the
startup,
shutdown,
and
malfunction
plan.
This
information

made
to
the
plan.
Records
would
be
required
of
information
needed
to

compliance
with

III.
Rationale
for
Selecting
the
Proposed
Standards
A.
How
Did
We
Select
the
Affected
Source?

Affected
source
means
the
collection
of
equipment,
activities,
or
both
within
a
single
contiguous
area
and
under
common
control
that
is
included
in
a
CAA
section
112(
c)
source
category
or
subcategory
for
which
a
CAA
section
112(
d)
standard
or
other
relevant
standard
is
established
pursuant
to
CAA
section
112.
The
affected
source
may
be
the
same
collection
of
equipment
and
processes
as
the
source
category
or
it
may
be
a
subset
of
the
source
category.
For
each
rule,
we
decide
which
individual
pieces
of
equipment
and
processes
warrant
separate
standards
in
the
context
of
the
CAA
section
112
requirements
and
the
industry
operating
practices.
We
considered
three
different
approaches
for
designating
the
affected
source:
the
entire
primary
magnesium
refinery,
groups
of
emission
points,
and
individual
emission
points.
In
selecting
the
affected
sources
for
the
proposed
rule,
we
identified
the
HAP­
emitting
operations,
the
HAP
emitted,
and
the
quantity
of
HAP
emissions
from
the
individual
or
groups
of
emission
points.
We
concluded
that
designating
the
entire
primary
magnesium
refinery
as
the
affected
source
is
the
most
appropriate
approach.
This
conclusion
is
consistent
with
the
requirements
for
defining
affected
source
provided
in
§
63.2
of
the
General
Provisions.
The
major
emission
points
include
each
spray
dryer,
magnesium
chloride
storage
bin,
melt/
reactor,
and
launder
off­
gas
system.
Therefore,
the
proposed
rule
includes
requirements
for
the
control
of
emissions
from
each
spray
dryer,
magnesium
chloride
storage
bin,
melt/
reactor,
and
launder
off­
gas
system.

B.
How
Did
We
Select
the
Pollutants?

The
proposed
standards
would
establish
emission
limits
for
chlorine,
hydrochloric
acid,
PM,
PM10,
and
dioxin/
furan.
Particulate
matter
was
selected
as
a
surrogate
for
HAP
metal
emissions
which
account
for
less
than
one­
tenth
of
one
percent
of
total
PM
emissions.
The
principal
HAP
metals
emitted
include
trace
quantities
of
phosphorous,
manganese,
and
chromium,
with
lesser
quantities
of
arsenic,
antimony,
and
mercury.
With
the
exception
of
elemental
mercury,
metal
HAP
emissions,
when
released,
are
a
constituent
of
total
PM.
As
a
result,
control
technologies
applied
for
PM
control
will
coincidentally
achieve
comparable
levels
of
control
of
these
pollutants.
Standards
requiring
good
control
of
PM
emissions
will
also
achieve
good
control
of
metal
HAP
emissions.
Establishing
separate
standards
for
these
individual
HAP
would
result
in
no
additional
reductions
beyond
that
achieved
using
PM
as
a
surrogate
pollutant.
Given
that
the
US
Magnesium
refinery
generates
about
three
pounds
of
chlorine
to
each
pound
of
magnesium
produced,
chlorine
and
hydrochloric
acid
are
by
far
the
most
significant
HAP
pollutants
potentially
emitted
from
primary
magnesium
refining.
As
such,
both
chlorine
and
hydrochloric
acid
were
selected
for
the
proposed
rule.
Lastly,
the
proposed
rule
would
establish
a
separate
emission
limit
for
dioxin/
furan
discharged
from
the
melt/
reactor
stack
because
of
the
high
toxicity
associated
with
very
low
exposures
to
these
compounds
and
their
persistence
and
bioaccumulative
effects
in
the
environment.

C.
How
Did
We
Determine
the
Bases
and
Levels
of
the
Proposed
Standards?
Since
there
is
only
one
primary
magnesium
refinery
in
the
source
category,
the
MACT
floor
for
both
existing
and
new
sources
is
established
by
the
performance
of
each
emissions
control
system
operating
at
that
source.
We
do
not
anticipate
the
construction
of
any
new
sources
in
this
source
category.
The
State
of
Utah,
Department
of
Environmental
Quality
(
UDEQ)
issued
a
title
V
operating
permit
dated
October
11,
2001
for
US
Magnesium
Corporation.
The
permit
contains
emission
limitations
for
chlorine,
hydrochloric
acid,
PM,
and
PM10
established
by
the
UDEQ.
The
permit
does
not
contain
limits
for
dioxin/
furan.
We
conducted
our
own
independent
assessment
of
the
emissions
test
data
and
concluded
that
the
emission
limitations
established
in
the
source's
title
V
operating
permit
are
appropriate
and
achievable.
Although
the
limited
test
results
indicate
the
permit
limits
are
achievable,
the
data
also
show
that

plant
is
not
significantly
overachieving
the
limits.
Therefore,
we
believe
that
the
permit
limits
reasonably
approximate
actual
emissions
and
performance
and
present
an
accurate
picture
of
the
level
of
control
achieved
by
the
best
performing
source.
An
underlying
presumption
when
setting
MACT
standards
is
that
all
emission
limitations
must
be
complied
with
at
all
times.
Consequently,
when
establishing
MACT
floors
and
ultimately
a
MACT
standard,
we
must
consider
the
long­
term
variability
in
performance
expected
to
occur
under
reasonable
worst­
case
conditions.
We
must
assure
that
an
ensuing
standard
reflects
the
level
of
emission
control
determined
to
be
MACT.
We
must
also
assure
that
the
standard
is
achievable
under
normal
and
recurring
worst­
case
circumstances.
As
part
of
our
development
of
the
proposed
MACT
standard,
we
assessed
the
viability
of
requiring
additional
or
different
control
equipment
to
obtain
beyond­
the­
floor
emissions
reductions.
Each
control
system
on
the
four
emission
points
(
i.
e.,
spray
dryer
stack,
magnesium
chloride
storage
bin
stack,
melt/
reactor
system
stack,
and
launder
off­
gas
system
stack)
was
evaluated
to
see
if
it
was
the
best
control
equipment
to
achieve
the
maximum
amount
of
reduction
of
chlorine,
hydrochloric
acid,
PM,
PM10,
and
dioxin/
furan.
For
all
four
emission
points,
US
Magnesium
uses
wet
scrubbers
(
packed­
bed
and
venturi
scrubbers)
to
achieve
the
emission
limits.
We
concluded
that
wet
scrubbing
systems
are
the
most
appropriate
and
practical
control
systems
for
chlorine,
hydrochloric
acid,
PM,
PM10,
and
dioxin/
furan
and
that
there
is
no
other
control
equipment
or
methods
of
control
that
would
be
more
effective
for
reducing
their
emissions
taking
into
consideration
cost
and
feasibility.
Therefore,
we
determined
that
the
emission
limitations
at
the
MACT
floors
also
represent
MACT.
We
also
propose
that
the
source
prepare
and
operate
according
to
a
fugitive
dust
emission
control
plan
that
describes
in
detail
the
measures
that
will
be
put
in
place
to
control
fugitive
dust
emissions
from
all
unpaved
roads
and
other
unpaved
operational
areas.
The
existing
fugitive
dust
emission
control
plan
that
has
been
approved
as
part
of
the
source's
title
V
permit
would
be
acceptable.

Spray
Dryers
There
are
three
spray
dryers
in
the
source
category.
The
exhaust
gas
from
each
is
controlled
by
two
venturi
scrubbers
followed
by
a
packed­
bed
scrubber.
All
three
dryers
are
subject
to
Utah's
PM
emission
limit
of
100
lbs/
hr.
Each
test
was
conducted
according
to
EPA
Method
5,
and,
as
far
as
we
know,
under
normal
and
representative
operating
conditions.
We
have
seven
PM
emission
tests
for
the
three
dryers.
Dryers
01
and
03
were
tested
in
May
1997;
dryers
01
and
02
were
tested
in
December
1997;
and
all
three
dryers
were
tested
in
June
2002.
The
May
1997
test
includes
seven
runs,
and
the
other
two
tests
include
three
runs
each.
The
test
results
of
all
seven
tests
range
from
25
to
53
lbs/
hr.
The
average
and
median
values
are
37
lbs/
hr
and
36
lbs/
hr,
respectively.
We
evaluated
the
existing
State
PM
emission
limit
as
an
option
for
establishing
the
MACT
floor.
The
test
results
recorded
range
from
about
onefourth
to
one­
half
of
the
standard
and
average
a
little
more
than
one­
third
of
the
standard.
Considering
that
a
reasonable
margin
of
safety
is
necessary
to
assure
continuous
compliance,
the
existing
State
limit
of
100
lbs/
hr
appears
to
be
a
reasonable
proxy
of
actual
performance,
and
as
such,
is
appropriate
for
establishing
the
MACT
floor.
We
have,
therefore,
determined
the
MACT
floor
for
spray
dryers
to
be
the
level
of
control
indicated
by
the
existing
State
limit
of
100
lbs/
hr
of
PM.
All
three
dryers
are
subject
to
Utah's
hydrochloric
acid
emission
limit
of
200
lbs/
hr.
We
have
seven
hydrochloric
acid
emission
tests
conducted
according
to
EPA
Method
26A
for
the
three
dryers.
Dryers
01
and
03
were
tested
in
May
1997;
dryers
01
and
02
were
tested
in
December
1997;
and
all
three
dryers
were
tested
in
June
2002.
The
May
1997
test
included
seven
runs,
and
the
other
two
tests
included
three
runs
each.
Again,
as
far
as
we
can
determine,
each
test
was
performed
under
normal
and
representative
conditions.
The
test
results
of
all
seven
tests
range
from
51
to
82
lbs/
hr
and
average
68
lbs/
hr.
The
median
value
is
also
68
lbs/
hr.
We
evaluated
the
existing
State
hydrochloric
acid
emission
limit
as
an
option
for
establishing
the
MACT
floor.
The
test
results
recorded
range
from
about
one­
fourth
to
almost
one­
half
of
the
standard
and
average
about
onethird
of
the
standard.
Considering
that
a
reasonable
margin
of
safety
is
necessary
to
assure
continuous
compliance,
the
existing
State
limit
of
200
lbs/
hr
appears
to
be
a
reasonable
proxy
of
actual
performance,
and
as
such,
is
appropriate
for
establishing
the
MACT
floor.
We
have,
therefore,
determined
the
MACT
floor
for
spray
dryers
to
be
the
level
of
control
indicated
by
the
existing
State
limit
of
200
lbs/
hr
of
hydrochloric
acid.
We
next
examined
possibilities
for
beyond­
the­
floor
options.
We
concluded
that
the
current
multi­
stage
wet
scrubbing
system
is
the
best
available
control
technology
for
the
removal
of
hydrochloric
acid
and
particulate
matter
contained
in
the
spray
dryer
discharge.
Therefore,
we
have
selected
the
mass
rate
emission
limits
established
in
the
source's
title
V
operating
permit
as
MACT
for
both
new
and
existing
spray
dryers.

Magnesium
Chloride
Storage
Bins
Magnesium
chloride
powder
from
the
spray
dryers
is
pneumatically
conveyed
to
storage
bins.
The
exhaust
air
from
the
conveyor
contains
particle
matter
and
low
levels
of
hydrochloric
acid.
The
exhaust
gases
are
directed
to
vertical
packed­
bed
scrubbers
where
hydrochloric
acid
and
particulate
matter
are
removed.
The
source's
title
V
operating
permit
limits
hydrochloric
acid
to
47.5
lbs/
hr
and
PM10
to
2.7
lbs/
hr.
Packed
bed
scrubbers
are
used
to
achieve
these
emission
limits.
We
do
not
have
any
emissions
test
data
for
this
emission
point.
As
such,
we
decided
to
adopt
the
source's
title
V
operating
permit
limits
for
PM10
and
hydrochloric
acid.
Emissions
testing
was
recently
conducted
on
the
magnesium
chloride
storage
bins,
and
we
expect
test
results
within
a
few
weeks
of
publishing
the
proposed
rule.
This
data
will
be
added
to
the
public
docket
as
soon
as
we
receive
it,
and
we
will
consider
the
data
and
public
comments
prior
to
publication
of
the
final
rule.
We
evaluated
this
wet
scrubbing
system
for
any
potential
beyond­
thefloor
control
technology
and
concluded
that
the
packed­
bed
scrubber
system
is
the
best
available
control
technology
for
the
removal
of
hydrochloric
acid
and
particulate
matter.
Thus,
we
adopted
the
emission
limits
established
in
the
source's
title
V
operating
permit
as
MACT.

Melt/
Reactor
The
melt/
reactor
system
melts
and
chlorinates
dehydrated
brine
powder
to
produce
high
purity
molten
magnesium
chloride
feed
for
electrolysis.
The
melt/
reactor
off­
gases
are
cooled
in
a
quench
tower
and
then
enter
a
venturi
scrubber
where
PM
is
removed.
The
off­
gases
are
then
directed
to
the
chlorine
reduction
burner
where
they
are
combined
with
tail
gases
from
the
chlorine
plant
and
burned
with
natural
gas
to
form
hydrochloric
acid.
The
gases
exit
the
chlorine
reduction
burner
and
enter
a
scrubber
train
where
hydrochloric
acid
is
recovered.
The
train
consists

The

range

We
evaluated
the

as

The
test
results
average
about
onethird

Considering
that
a
reasonable

is
necessary
to

the
existing
State

of
13.1
lbs/

appears
to
be
a
reasonable
proxy
of
actual

and
as
such,
is
appropriate
for
establishing
the
MACT

We
have,
therefore,
determined
the
MACT
floor
for
the
melt/
reactor
to
be
the
level
of
control
indicated
by
the
existing
State

of
13.1
lbs/

of
PM10.
We
have
two
hydrochloric
acid
emission
tests
for
the
melt/
reactor.
The
tests
were
conducted
in
May
1995
and
May
2000
in
accordance
with
Method
26A.
We
believe
that
each
test
was
performed
under
normal
and
representative
operating
conditions.
The
May
1995
test
results
average
3.2
lbs/

and
the
May
2000
test
results
average
2.8
lbs/

We
evaluated
the
existing
State

as
an
option
for
establishing
the
MACT

A
comparison
of
the
State
limit
of
7.2

to
the
actual
hydrochloric

indicates
that
the
State

is
a

and
as

is

Consequently,
we

for

to
be

of

indicated
by
the

We
have

for

reactor.
The
test
were
conducted
in
May

and
May
2000
in

with
EPA

The
May

average
21
lbs/

and
the
May

average
50

Again,
we
believe
that
each

was
performed
under
normal
and
representative

We
evaluated
the
existing
State

as
an

the
MACT

A
comparison
of
the
State
limit
of
100

to
the
actual

indicates
that
the
State

g/
year)
and
emissions
expressed
in
terms
of
TEQ
of
less
than
3
g/
year.
The
current
title
V
operating
permit
includes
no
limitations
on
the
emissions
of
dioxin/
furan
or
any
surrogate
pollutant.
As
previously
stated,
emission
controls
applied
to
the
melt/
reactor
discharge
include
three
packed
bed
scrubbers
in
series
followed
by
a
venturi
scrubber
for
the
control
of
hydrochloric
acid
and
PM.
Although
not
installed
specifically
for
dioxin/
furan
control,
we
believe
that
some
incidental
control
of
dioxin/
furan
is
in
fact
achieved
by
these
scrubbers
and
that
the
floor
level
of
control
is
represented
by
the
available
information
on
actual
emissions.
Specifically,
we
have
data
on
two
tests
conducted
in
March
of
1998
and
May
of
2000.
Each
test
is
comprised
of
three
test
runs
conducted
in
accordance
with
EPA
Method
23.1
The
1998
TEQ
test
results
range
from
12.0
to
25.2
ng/
dscm
corrected
to
7
percent
oxygen
and
average
19
ng/
dscm
corrected
to
7
percent
oxygen.
The
2000
TEQ
results
range
from
10.4
to
35.9
ng/
dscm
corrected
to
7
percent
oxygen
and
average
24
ng/
dscm
corrected
to
7
percent
oxygen.
The
precision
evidenced
in
the
two
tests,
suggests
that
the
variability
due
to
process
variations
and
control
device
performance
is
narrow,
with
the
average
results
of
both
tests
within
±
20
percent.
We
chose
the
highest
of
the
individual
runs,
i.
e.,
36
ng
TEQ/
dscm
corrected
to
7
percent
oxygen
as
a
representative
value
of
the
performance
level
that
can
be
achieved.
Thus,
we
have
chosen
36
ng
TEQ/
dscm
as
the
MACT
floor.
The
source
plans
to
conduct
additional
emissions
testing
in
the
near­
term.
We
expect
the
testing
to
occur
between
proposal
and
promulgation.
In
determining
the
final
standard
for
dioxin/
furan,
we
will
consider
the
results
of
the
new
test
in
addition
to
public
comments
that
we
receive.
We
evaluated
this
multi­
stage
scrubbing
system
for
any
potential
improvement
to
go
beyond­
the­
floor.
We
concluded
that
the
current
scrubbing
system
is
the
best
control
option
for
removal
of
chlorine,
hydrochloric
acid,
and
PM10.
For
dioxin/
furan,
we
examined
a
beyond­
the­
floor
alternative,
and
determined
that
the
next
increment
of
control
beyond­
the­
floor
is
the
installation
of
a
baghouse
equipped
with
a
catalytic
filter
that
destroys
gaseous
dioxins
and
furans.
We
estimate
the
additional
capital
cost
of
adding
baghouses
to
be
$
650,000
and
the
total
annualized
cost
to
be
$
390,000
per
year.
We
estimate
the
emissions
reductions
to
be
2.4
grams
per
year
resulting
in
a
cost
per
gram
of
total
dioxin/
furan
reduction
of
$
163,865.
We
believe
that
the
high
cost,
coupled
with
the
small
reduction
in
dioxin/
furan
emissions,
does
not
justify
the
beyond­
the­
floor
alternative
at
this
time.
Consequently,
we
chose
the
floor
level
of
control
of
36
ng
TEQ/
dscm
as
MACT.

Launder
Off­
Gas
System
The
launder
off­
gas
system
(
LOG)
collects
fugitive
emissions
from
the
melt
reactor
area
(
i.
e.
hoods
and
launders).
The
collected
fugitive
gases
enter
a
horizontally
aligned
packed
scrubber
where
chlorine,
hydrochloric
acid,
and
particulate
matter
are
removed
by
scrubbing
with
water.
The
LOG
scrubbed
gases
are
exhausted
to
the
atmosphere,
and
the
scrubber
water
is
returned
to
the
waste
water
collection
system.
We
have
three
PM
emission
tests
for
the
launder
off­
gas
system.
The
launder
off­
gas
system
was
tested
in
August
1993,
July
1998,
and
January
1999
using
EPA
Method
5,
and
as
far
as
we
know,
under
normal
and
representative
operating
conditions.
The
test
results
of
the
three
tests
range
from
2.6
to
19.1
lbs/
hr
and
average
7.0
lbs/
hr.
We
evaluated
the
existing
State
PM
emission
limit
as
an
option
for
establishing
the
MACT
floor.
We
compared
the
State
limit
of
37.5
lbs/
hr
to
the
actual
PM
emissions
data.
Considering
that
a
reasonable
margin
of
safety
is
necessary
to
assure
continuous
compliance,
the
existing
State
limit
of
37.5
lbs/
hr
appears
to
be
a
reasonable
proxy
of
actual
performance,
and
as
such,
is
appropriate
for
establishing
the
MACT
floor.
Therefore,
we
determined
the
MACT
floor
for
the
launder
off­
gas
system
to
be
the
level
of
control
indicated
by
the
existing
State
limit
of
37.5
lbs/
hr
of
PM.
We
have
three
hydrochloric
acid
emission
tests
for
the
launder
off­
gas
system.
The
launder
off­
gas
system
was
tested
in
August
1993,
July
1998,
and
January
1999
using
EPA
Method
26A.
We
believe
that
the
tests
were
performed
under
normal
and
representative
operating
conditions.
The
test
results
of
the
three
tests
range
from
6.84
to
32.6
lbs/
hr
and
average
15.6
lbs/
hr.
We
evaluated
the
existing
State
hydrochloric
acid
emission
limit
as
an
option
for
establishing
the
MACT
floor.

Proposed
Rules
Considering
that
a
reasonable
margin
of
safety
is
necessary
to
assure
continuous
compliance,
the
existing
State
limit
of
46.0
lbs/
hr
appears
to
be
a
reasonable
proxy
of
actual
performance,
and
as
such,
is
appropriate
for
establishing
the
MACT
floor.
Consequently,
we
determined
the
MACT
floor
for
the
launder
off­
gas
system
to
be
the
level
of
control
indicated
by
the
existing
State
limit
of
46.0
lbs/
hr
of
hydrochloric
acid.
We
have
three
chlorine
emission
tests
for
the
launder
off­
gas
system.
The
launder
off­
gas
system
was
tested
in
August
1993
and
January
1999
using
EPA
Method
26.
We
believe
the
tests
were
performed
under
normal
and
representative
operating
conditions.
The
test
results
of
the
three
tests
range
from
16.6
to
25.9
lbs/
hr
and
average
19.9
lbs/
hr.
We
evaluated
the
existing
State
chlorine
emission
limit
as
an
option
for
establishing
the
MACT
floor.
Considering
that
a
reasonable
margin
of
safety
is
necessary
to
assure
continuous
compliance,
the
existing
State
limit
of
26.0
lbs/
hr
appears
to
be
a
reasonable
proxy
of
actual
performance,
and
as
such,
is
appropriate
for
establishing
the
MACT
floor.
Consequently,
we
determined
the
MACT
floor
for
the
launder
off­
gas
system
to
be
the
level
of
control
indicated
by
the
existing
State
limit
of
26.0
lbs/
hr
of
chlorine.
We
evaluated
potential
beyond­
thefloor
options
and
concluded
that
the
existing
scrubber
is
the
best
available
control
technology
for
the
removal
of
chlorine,
hydrochloric
acid,
and
PM
contained
in
the
launder
off­
gas
system
discharge.
Therefore,
we
selected
the
emission
limits
established
in
the
source's
title
V
operating
permit
as
MACT.

D.
How
Did
We
Select
the
Initial
Compliance
Requirements?
The
proposed
rule
requires
a
performance
test
for
each
control
device
to
demonstrate
initial
compliance
with
the
applicable
PM,
PM10,
chlorine
and
hydrochloric
acid
limits
using
the
specified
testing
methods
in
40
CFR
part
60,
appendix
A.
We
have
also
specified
procedures
to
ensure
that
control
equipment
is
operating
properly
for
initial
compliance.
Venturi
scrubbers
and
packed­
bed
scrubbers
must
be
monitored
for
scrubber
water
flow
rate
and
pressure
drop.
If
a
facility
uses
controls
other
than
wet
scrubbers
or
packed­
bed
scrubbers
to
control
emissions
from
an
affected
source,
the
owner
or
operator
would
be
required
to
send
us
a
monitoring
plan
containing
information
on
the
type
of
device,
performance
test
results,
appropriate
operating
parameters
to
be
monitored,
operating
limits,
and
operation
and
maintenance.

E.
How
Did
We
Select
the
Continuous
Compliance
Requirements?
For
continuous
compliance,
we
chose
periodic
performance
testing
for
PM,
PM10,
chlorine,
hydrochloric
acid,
and
dioxin/
furan
which
is
consistent
with
current
permit
requirements.
In
general,
performance
tests
are
repeated
every
2.5
to
5
years,
depending
on
the
magnitude
of
the
source.
Consequently,
we
decided
that
performance
tests
should
be
repeated
no
less
frequently
than
twice
per
permit
term
of
a
source's
title
V
operating
permit
(
at
mid­
term
and
renewal).
We
also
specified
procedures
to
ensure
that
control
equipment
is
operated
properly
on
a
continuous
basis.
Venturi
scrubbers
and
packed­
bed
scrubbers
must
be
monitored
for
pressure
drop
and
scrubber
water
flow
rate.
If
a
facility
uses
controls
other
than
wet
scrubbers
to
control
emissions
from
an
affected
source,
the
owner
or
operator
would
be
required
to
send
us
a
monitoring
plan
containing
information
on
the
type
of
device,
performance
test
results,
appropriate
operating
parameters
to
be
monitored,
operating
limits,
and
operation
and
maintenance.

F.
How
Did
We
Select
the
Notification,
Recordkeeping,
and
Reporting
Requirements?
We
selected
the
notification,
recordkeeping,
and
reporting
requirements
to
be
consistent
with
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A).
One­
time
notifications
are
required
by
EPA
to
know
what
facilities
are
subject
to
the
standard,
if
a
facility
has
complied
with
the
rule
requirements,
and
when
certain
events
such
as
performance
tests
and
performance
evaluations
are
scheduled.
Semiannual
compliance
reports
containing
information
on
any
deviation
from
the
proposed
rule
requirements
are
also
required.
These
reports
would
include
information
on
any
deviation
that
occurred
during
the
reporting
period;
if
no
deviation
occurred,
only
summary
information
would
be
required.
Consistent
with
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
we
also
require
an
immediate
report
of
any
startup,
shutdown,
or
malfunction
where
the
actions
taken
in
response
were
not
consistent
with
the
startup,
shutdown,
and
malfunction
plan.
This
information
is
needed
to
determine
if
changes
to
the
plan
need
to
be
made.
Records
would
be
required
of
information
needed
to
document
compliance
with
the
proposed
rule
requirements.
These
notifications,
reports,
and
records
are
the
minimum
needed
to
ensure
initial
and
continuous
compliance.

IV.
Summary
of
Environmental,
Energy
and
Economic
Impacts
Generally,
we
do
not
expect
the
impacts
of
the
proposed
rule
to
be
very
significant.
Currently,
the
one
operating
refinery
has
all
of
the
required
air
pollution
control
equipment
in
place
and
operating.
The
only
impacts
will
be
the
estimated
cost
of
$
48,000
for
the
additional
monitoring,
recordkeeping
and
reporting
requirements
required
by
the
proposed
rule.

V.
Solicitation
of
Comments
and
Public
Participation
We
seek
full
public
participation
in
arriving
at
final
decisions
and
encourage
comments
on
all
aspects
of
the
proposed
rule
from
all
interested
parties.
You
need
to
submit
full
supporting
data
and
detailed
analysis
with
your
comments
to
allow
us
to
make
the
best
use
of
them.

Administrative
Requirements
A.
Executive
Order
12866,
Regulatory
Planning
and
Review
Under
Executive
Order
12866
(
58
FR
51735,
October
4,
1993),
the
EPA
must
determine
whether
the
regulatory
action
is
``
significant''
and,
therefore,
subject
to
review
by
the
Office
of
Management
and
Budget
(
OMB)
and
the
requirements
of
the
Executive
Order.
The
Executive
Order
defines
a
``
significant
regulatory
action''
as
one
that
is
likely
to
result
in
a
rule
that
may:
(
1)
Have
an
annual

of
$
100
million
or
more
or
adversely
affect
in
a
material
way
the
economy,
a
sector
of
the
economy,
productivity,
competition,
jobs,
the
environment,
public
health
or
safety,
or
State,
local,
or
tribal
governments
or
communities;
(
2)
Create
a
serious
inconsistency
or
otherwise
interfere
with
an
action
taken
or
planned
by
another
agency;
(
3)
Materially
alter
the
budgetary
impact
of
entitlement,

because
none
of

Consequently,
the

was
not

B.
Executive
Order
13132,
Federalism
Executive
Order
13132,
entitled
``
Federalism''
(
64
FR
43255,
August
10,
1999),
requires
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
State
and
local
officials
in
the
development
of
regulatory
policies
that
have
federalism
implications.''
``
Policies
that
have
federalism
implications''
is
defined
in
the
Executive
Order
to
include
regulations
that
have
``
substantial
direct
effects
on
the
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government.''
Under
Executive
Order
13132,
EPA
may
not
issue
a
regulation
that
has
federalism
implications,
that
imposes
substantial
direct
compliance
costs,
and
that
is
not
required
by
statute,
unless
the
Federal
government
provides
the
funds
necessary
to
pay
the
direct
compliance
costs
incurred
by
State
and
local
governments,
or
EPA
consults
with
State
and
local
officials
early
in
the
process
of
developing
the
proposed
regulation.
The
EPA
also
may
not
issue
a
regulation
that
has
federalism
implications
and
that
preempts
State
law
unless
the
EPA
consults
with
State
and
local
officials
early
in
the
process
of
developing
the
proposed
regulation.
If
EPA
complies
by
consulting,
Executive
Order
13132
requires
EPA
to
provide
to
OMB,
in
a
separately
identified
section
of
the
preamble
to
the
rule,
a
federalism
summary
impact
statement
(
FSIS).
The
FSIS
must
include
a
description
of
the
extent
of
EPA's
prior
consultation
with
State
and
local
officials,
a
summary
of
the
nature
of
their
concerns
and
the
agency's
position
supporting
the
need
to
issue
the
regulation,
and
a
statement
of
the
extent
to
which
the
concerns
of
State
and
local
officials
have
been
met.
Also,
when
EPA
transmits
a
draft
final
rule
with
federalism
implications
to
OMB
for
review
pursuant
to
Executive
Order
12866,
EPA
must
include
a
certification
from
the
Agency's
Federalism
Official
stating
that
EPA
met
the
requirements
of
Executive
Order
13132
in
a
meaningful
and
timely
manner.
The
proposed
rule
does
not
have
federalism
implications.
None
of
the
affected
facilities
are
owned
or
operated
by
State
governments,
and
the
proposed
rule
would
not
preempt
any
State
laws
that
are
more
stringent.
Therefore,
it
will
not
have
substantial
direct
effects
on
the
States,
on
the
relationship
between
the
national
government
and
the
States,
or
on
the
distribution
of
power
and
responsibilities
among
the
various
levels
of
government,
as
specified
in
Executive
Order
13132.
In
addition,
the
proposed
rule
is
required
by
statute
and,
if
implemented,
will
not
impose
any
substantial
direct
compliance
costs.
Thus,
the
requirements
of
section
6
of
the
Executive
Order
do
not
apply
to
this
proposed
rule.

C.
Executive
Order
13175,
Consultation
and
Coordination
With
Indian
Tribal
Governments
Executive
Order
13175,
entitled
``
Consultation
and
Coordination
with
Indian
Tribal
Governments''
(
65
FR
67249,
November
6,
2000),
requires
the
EPA
to
develop
an
accountable
process
to
ensure
``
meaningful
and
timely
input
by
tribal
officials
in
the
development
of
regulatory
policies
that
have
tribal
implications.''
``
Policies
that
have
tribal
implications''
is
defined
in
the
Executive
Order
to
include
regulations
that
have
``
substantial
direct
effects
on
one
or
more
Indian
tribes,
on
the
relationship
between
the
Federal
government
and
the
Indian
tribes,
or
on
the
distribution
of
power
and
responsibilities
between
the
Federal
Government
and
Indian
tribes.''
The
proposed
rule
does
not
have
tribal
implications.
It
will
not
have
substantial
direct
effects
on
tribal
governments,
on
the
relationship
between
the
Federal
government
and
Indian
tribes,
or
on
the
distribution
of
power
and
responsibilities
between
the
Federal
Government
and
Indian
tribes,
as
specified
in
Executive
Order
13175.
Thus
Executive
order
13175
does
not
apply
to
the
proposed
rule.
In
the
spirit
of
Executive
Order
13175
and
consistent
with
EPA
policy
to
promote
communications
between
EPA
and
tribal
governments,
EPA
specifically
solicits
additional
comment
on
the
proposed
rule
from
tribal
officials.

D.
Executive
Order
13045,
Protection
of
Children
From
Environmental
Health
Risks
and
Safety
Risks
Executive
Order
13045
(
62
FR
19885,
April
23,
1997)
applies
to
any
rule
that:
(
1)
Is
determined
to
be
``
economically
significant,''
as
defined
under
Executive
Order
12866,
and
(
2)
concerns
an
environmental
health
or
safety
risk
that
EPA
has
reason
to
believe
may
have
a
disproportionate
effect
on
children.
If
the
regulatory
action
meets
both
criteria,
the
EPA
must
evaluate
the
environmental
health
or
safety
effects
of
the
planned
rule
on
children
and
explain
why
the
planned
regulation
is
preferable
to
other
potentially
effective
and
reasonably
feasible
alternatives
considered
by
the
Agency.
The
EPA
interprets
Executive
Order
13045
as
applying
only
to
those
regulatory
actions
that
are
based
on
health
or
safety
risks,
such
that
the
analysis
required
under
section
5
 
501
of
the
Executive
Order
has
the
potential
to
influence
the
regulation.
This
proposed
rule
is
not
subject
to
Executive
Order
13045
because
it
is
technology
based
and
not
based
on
health
or
safety
risks.
No
children's
risk
analysis
was
performed
because
no
alternative
technologies
exist
that
would
provide
greater
stringency
at
a
reasonable
cost.
Further,
the
proposed
rule
has
been
determined
not
to
be
``
economically
significant''
as
defined
under
Executive
Order
12866.

E.
Unfunded
Mandates
Reform
Act
of
1995
Title
II
of
the
Unfunded
Mandates
Reform
Act
of
1995
(
UMRA),
Pub.
L.
104
 
4,
establishes
requirements
for
Federal
agencies
to
assess
the
effects
of
their
regulatory
actions
on
State,
local,
and
tribal
governments
and
the
private
sector.
Under
section
202
of
the
UMRA,
the
EPA
generally
must
prepare
a
written
statement,
including
a
costbenefit
analysis,
for
proposed
and
final
rules
with
``
Federal
mandates''
that
may
result
in
expenditures
by
State,
local,
and
tribal
governments,
in
the
aggregate,
or
by
the
private
sector,
of
$
100
million
or
more
in
any
1
year.
Before
promulgating
an
EPA
rule
for
which
a
written
statement
is
needed,
section
205
of
the
UMRA
generally
requires
the
EPA
to
identify
and
consider
a
reasonable
number
of
regulatory
alternatives
and
adopt
the
least
costly,
most
costeffective
or
least­
burdensome
alternative
that
achieves
the
objectives
of
the
rule.
The
provisions
of
section
205
do
not
apply
when
they
are
inconsistent
with
applicable
law.
Moreover,
section
205
allows
the
EPA
to
adopt
an
alternative
other
than
the
leastcostly
most
cost­
effective,
or
leastburdensome
alternative
if
the
Administrator
publishes
with
the
final
rule
an
explanation
why
that
alternative
was
not
adopted.
Before
the
EPA
establishes
any
regulatory
requirements
that
may
significantly
or
uniquely
affect
small
governments,
including
tribal
governments,
it
must
have
developed
under
section
203
of
the
UMRA
a
small
government
agency
plan.
The
plan
must
provide
for
notifying
potentially
affected
small
governments,
enabling
officials
of
affected
small
governments
to
have
meaningful
and
timely
input
in
the
development
of
EPA

Proposed
Rules
proposals
with
significant
Federal
intergovernmental
mandates,
and
informing,
educating,
and
advising
small
governments
on
compliance
with
the
regulatory
requirements.
The
EPA
has
determined
that
the
proposed
rule
does
not
contain
a
Federal
mandate
that
may
result
in
estimated
costs
of
$
100
million
or
more
to
either
State,
local,
or
tribal
governments,
in
the
aggregate,
or
to
the
private
sector
in
any
1
year.
The
maximum
total
annual
cost
of
the
proposed
rule
for
any
year
has
been
estimated
to
be
less
than
$
48,000.
Thus,
today's
proposed
rule
is
not
subject
to
sections
202
and
205
of
the
UMRA.
In
addition,
the
EPA
has
determined
that
the
proposed
rule
contains
no
regulatory
requirements
that
might
significantly
or
uniquely
affect
small
governments
because
it
contains
no
requirements
that
apply
to
such
governments
or
impose
obligations
upon
them.
Therefore,
today's
proposed
rule
is
not
subject
to
the
requirements
of
section
203
of
the
UMRA.

F.
Regulatory
Flexibility
Act
(
RFA),
as
Amended
by
the
Small
Business
Regulatory
Enforcement
Fairness
Act
of
1996
(
SBREFA),
5
U.
S.
C.
et
seq.
The
RFA
generally
requires
an
agency
to
prepare
a
regulatory
flexibility
analysis
of
any
rule
subject
to
notice
and
comment
rulemaking
requirements
under
the
Administrative
Procedure
Act
or
any
other
statute
unless
the
agency
certifies
that
the
rule
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
Small
entities
include
small
businesses,
small
organizations,
and
small
governmental
jurisdictions.
For
purposes
of
assessing
the
impacts
of
today's
proposed
rule
on
small
entities,
small
entity
is
defined
as:
(
1)
A
small
business
according
to
Small
Business
Administration
(
SBA)
size
standards
for
NAICS
code
331419
(
i.
e.,
Primary
Magnesium
Refining)
of
1,000
or
fewer
employees;
(
2)
a
small
governmental
jurisdiction
that
is
a
government
of
a
city,
county,
town,
school
district
or
special
district
with
a
population
of
less
than
50,000;
and
(
3)
a
small
organization
that
is
any
not­
forprofit
enterprise
which
is
independently
owned
and
operated
and
is
not
dominant
in
its
field.
Based
on
the
above
definition
of
small
entities,
the
Agency
has
determined
that
there
are
no
small
businesses
within
this
source
category
that
would
be
subject
to
the
proposed
rule.
Therefore,
because
the
proposed
rule
will
not
impose
any
requirements
on
small
entities,
EPA
certifies
that
this
action
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.

G.
Paperwork
Reduction
Act
The
information
collection
requirements
in
the
proposed
rule
will
be
submitted
for
approval
to
OMB
under
the
Paperwork
Reduction
Act,
44
U.
S.
C.
3501
et
seq.
An
information
collection
request
(
ICR)
document
has
been
prepared
by
EPA
(
ICR

and
a

A
copy
also
may
be
downloaded
off
the
Internet
at
http://
www.
epa.
gov/
icr.
The
information
requirements
are
not
effective
until
OMB
approves
them.
The
information
requirements
are
based
on
notification,
recordkeeping,
and
reporting
requirements
in
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
which
are
mandatory
for
all
operators
subject
to
NESHAP.
These
recordkeeping
and
reporting
requirements
are
specifically
authorized
by
section
112
of
the
CAA
(
42
U.
S.
C.
7414).
All
information
submitted
to
the
EPA
pursuant
to
the
recordkeeping
and
reporting
requirements
for
which
a
claim
of
confidentiality
is
made
is
safeguarded
according
to
Agency
policies
in
40
CFR
part
2,
subpart
B.
The
proposed
rule
would
require
applicable
one­
time
notifications
required
by
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A)
for
each
affected
source.
As
required
by
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
all
plants
would
be
required
to
prepare
and
operate
by
a
startup,
shutdown,
and
malfunction
plan.
Plants
also
would
be
required
to
prepare
an
operation
and
maintenance
plan
for
capture
systems
and
control
devices
subject
to
operating
limits.
Records
would
be
required
to
demonstrate
continuous
compliance
with
the
monitoring,
operation,
and
maintenance
requirements
for
capture
systems,
control
devices,
and
monitoring
systems.
Semiannual
compliance
reports
also
are
required.
These
reports
would
describe
any
deviation
from
the
standards,
any
period
a
continuous
monitoring
system
was
out­
of­
control,
or
any
startup,
shutdown,
or
malfunction
event
where
actions
taken
to
respond
were
inconsistent
with
startup,
shutdown,
and
malfunction
plan.
If
no
deviation
or
other
event
occurred,
only
a
summary
report
would
be
required.
Consistent
with
the
NESHAP
General
Provisions
(
40
CFR
part
63,
subpart
A),
if
actions
taken
in
response
to
a
startup,
shutdown,
or
malfunction
event
are
not
consistent
with
the
plan,
an
immediate
report
must
be
submitted
within
2
days
of
the
event
with
a
letter
report
7
days
later.
The
annual
public
reporting
and
recordkeeping
burden
for
this
collection
of
information
averaged
over
the
first
3
years
after
[
DATE
THE
FINAL
RULE
IS
PUBLISHED
IN
THE

is
estimated
to
total
731
labor
hours
per
year
at
a
total
annual
cost
of
$
43,289,
including
labor,
capital,
and
operation
and
maintenance.
Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
persons
to
generate,
maintain,
retain,
or
disclose
or
provide
information
to

for
the
purpose
of

to
comply
with
any
previously
applicable
instructions
and
requirements;
train
personnel
to

of
information;
search
existing
data
sources;
complete
and
review
the
collection
of
information;
and
transmit
or
otherwise
disclose
the
information.
An
Agency
may
not
conduct
or
sponsor,
and
a
person
is
not
required
to
respond
to,
a
collection
of
information
unless
it
displays
a
currently
valid
OMB
control
number.
The
OMB
control
number
for
EPA's
regulations
are
listed
in
40
CFR
part
9
and
48
CFR
chapter
15.
Comments
are
requested
on
the
EPA's
need
for
this
information,
the
accuracy
of
the
burden
estimates,
and
any
suggested
methods
for
minimizing
respondent

including
through
the

directs
EPA
to

consensus
standards
in
their
regulatory
and
procurement
activities
unless
to
do
so
would
be
inconsistent
with
applicable
law
or
otherwise
impracticable.
Voluntary
consensus
standards
are
technical
standards
(
such
as
material
specifications,
test
methods,
sampling
procedures,
business
practices)
developed
or
adopted
by
one
or
more
voluntary

The
NTTAA
directs
EPA
to
provide
Congress,
through
annual
reports
to
OMB,
with
explanations
when
an
agency
does
not
use
available

ACTION:
Proposed
rule.

SUMMARY:
The
Environmental
Protection
Agency
(
EPA)
is
proposing
to
amend
the
EPA
Acquisition
Regulation
(
EPAAR)
to
add
a
clause
requiring
contractors
(
and
subcontractors)
to
perform
background
checks
and
make
suitability
determinations
for
contractor
(
and
subcontractor)
employees
performing
services
on
or
within
Federally­
owned
or
leased
space
and
facilities,
commercial
space
primarily
occupied
by
Federal
employees,
and
Superfund,
Oil
Pollution
Act,
and
Stafford
Act
sites.
The
clause
will
require
contractors
(
and
subcontractors)
to
perform
background
checks
and
make
suitability
determinations
on
their
employees
before
the
employees
can
perform
onsite
contract
services
for
the
EPA.
Contracting
Officers
will
be
allowed
to
waive
the
requirements
of
the
clause
on
a
case­
by­
case
basis.
The
process
contemplated
by
the
clause
will
allow
EPA
to
mitigate
any
actual
or
potential
threat
to
the
public
health,
welfare
and
the
environment.
