Characterization/
Abstract
The
National
Emission
Standards
for
Hazardous
Air
Pollutants
(
NESHAP)
for
Inorganic
Arsenic
Emissions
from
Glass
Manufacturing
Plants
(
40
CFR
Part
61,
Subpart
N)
were
proposed
on
July
20,
1983,
and
promulgated
on
August
4,
1986.
The
standards
were
amended
on
May
31,
1990,
to
add
an
alternative
test
method.
These
standards
apply
to
each
glass
melting
furnace
that
uses
commercial
arsenic
as
a
raw
material.
These
standards
do
not
apply
to
pot
furnaces.
Also,
rebricking
is
not
considered
construction
or
modification
for
the
purposes
of
40
CFR
Section
61.05.
This
information
is
being
collected
to
assure
compliance
with
40
CFR
Part
61,
Subpart
N.

In
general,
all
NESHAP
standards
require
initial
notifications,
performance
tests,
and
periodic
reports.
Owners
or
operators
are
also
required
to
maintain
records
of
the
occurrence
and
duration
of
any
startup,
shutdown,
or
malfunction
in
the
operation
of
an
affected
facility,
or
any
period
during
which
the
monitoring
system
is
inoperative.
These
notifications,
reports,
and
records
are
essential
in
determining
compliance,
and
are
required
of
all
sources
subject
to
NESHAP.

Any
owner
or
operator
subject
to
the
provisions
of
this
part
shall
maintain
a
file
of
these
measurements,
and
retain
the
file
for
at
least
two
years
following
the
date
of
such
measurements,
maintenance
reports,
and
records.
All
reports
are
sent
to
the
delegated
State
or
local
authority.
In
the
event
that
there
is
no
such
delegated
authority,
the
reports
are
sent
directly
to
the
United
States
Environmental
Protection
Agency
(
EPA)
Regional
Office.

Approximately
28
sources
are
currently
subject
to
the
regulation,
and
it
is
estimated
that
no
new
sources
will
become
subject
to
the
regulation
in
the
next
three
years.

Need
for
and
Use
of
the
Collection
2(
a)
Need/
Authority
for
the
Collection
The
EPA
is
charged
under
Section
112
of
the
Clean
Air
Act,
as
amended,
to
establish
standards
of
performance
for
each
category
or
subcategory
of
major
sources
and
area
sources
of
hazardous
air
pollutants.
These
standards
are
applicable
to
new
or
existing
sources
of
hazardous
air
pollutants
and
shall
require
the
maximum
degree
of
emission
reduction.
In
addition,
Section
114(
a)
states
that
the
Administrator
may
require
any
owner
or
operator
subject
to
any
requirement
of
this
Act
to:

(
A)
Establish
and
maintain
such
records;
(
B)
make
such
reports;
(
C)
install,
use,
and
maintain
such
monitoring
equipment,
and
use
such
audit
procedures,
or
methods;
(
D)
sample
such
emissions
(
in
accordance
with
such
procedures
or
methods,
at
such
locations,
at
such
intervals,
during
such
periods,
and
in
such
manner
as
the
Administrator
shall
prescribe);
(
E)
keep
records
on
control
equipment
parameters,
production
variables
or
other
indirect
data
when
direct
monitoring
of
emissions
is
impractical;
(
F)
submit
compliance
certifications
in
accordance
with
Section
114(
a)(
3);
and
(
G)
provide
such
other
information
as
the
Administrator
may
reasonably
require.

In
the
Administrator's
judgment,
arsenic
emissions
from
glass
manufacturing
plants
cause
or
contribute
to
air
pollution
that
may
reasonably
be
anticipated
to
endanger
public
health
or
welfare.
Therefore,
NESHAP
were
promulgated
for
this
source
category
at
40
CFR
Part
61,
Subpart
N.

2(
b)
Practical
Utility/
Users
of
the
Data
The
control
of
emissions
of
arsenic
from
glass
manufacturing
plants
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
Emissions
of
arsenic
from
glass
manufacturing
plants
are
the
result
of
the
operation
of
the
affected
facilities.
The
subject
standards
are
achieved
by
the
capture
of
arsenic
emissions
using
emission
control
equipment
or
the
reduction
of
arsenic
added
to
the
glass
raw
materials.
The
notifications
required
in
the
applicable
regulations
are
used
to
inform
the
Agency
or
delegated
authority
when
a
source
becomes
subject
to
the
requirements
of
the
regulations.
The
reviewing
authority
may
then
inspect
the
source
to
check
if
the
pollution
control
devices
are
properly
installed
and
operated
and
the
regulations
are
being
met.
Performance
test
reports
are
needed
as
these
are
the
Agency's
record
of
a
source's
initial
capability
to
comply
with
the
emission
standards,
and
serve
as
a
record
of
the
operating
conditions
under
which
compliance
was
achieved.
Forecasts
of
arsenic
emissions
for
the
different
types
of
glass
melted
in
a
furnace
must
be
calculated
so
that
the
steps
necessary
to
achieve
compliance
are
anticipated.
The
semiannual
reports
are
used
for
problem
identification,
as
a
check
on
source
operation
and
maintenance,
and
for
compliance
determinations.
The
information
generated
by
the
monitoring,
recordkeeping
and
3
reporting
requirements
described
in
this
Information
Collection
Request
(
ICR)
is
used
by
the
Agency
to
ensure
that
facilities
affected
by
the
NESHAP
continue
to
operate
the
control
equipment
and
achieve
compliance
with
the
regulation.
Adequate
monitoring,
recordkeeping,
and
reporting
is
necessary
to
ensure
compliance
with
the
applicable
regulations,
as
required
by
the
Clean
Air
Act.
The
information
collected
from
recordkeeping
and
reporting
requirements
is
also
used
for
targeting
inspections,
and
is
of
sufficient
quality
to
be
used
as
evidence
in
court.

3.
Nonduplication,
Consultations,
and
Other
Collection
Criteria
The
recordkeeping
and
reporting
requested
are
required
under
40
CFR
Part
61,
Subpart
N.

3(
a)
Nonduplication
If
the
subject
standards
have
not
been
delegated,
the
information
is
sent
directly
to
the
appropriate
EPA
Regional
Office.
Otherwise,
the
information
is
sent
directly
to
the
delegated
State
or
local
agency.
If
a
State
or
local
agency
has
adopted
their
own
similar
standards
to
implement
the
Federal
standards,
a
copy
of
the
report
submitted
to
the
State
or
local
agency
can
be
sent
to
the
Administrator
in
lieu
of
the
report
required
by
the
Federal
standards.
Therefore,
no
duplication
exists.

3(
b)
Public
Notice
Required
Prior
to
ICR
Submission
to
OMB
An
announcement
of
a
public
comment
period
for
the
renewal
of
this
ICR
was
published
in
the
Federal
Register
on
October
29,
2001.
No
comments
were
received
on
the
burden
published
in
the
Federal
Register.

3(
c)
Consultations
There
has
been
consultation
with
two
national
glass
manufacturing
associations
to
estimate
the
number
of
facilities
subject
to
this
standard.
However,
neither
association
was
able
to
provide
an
accurate
estimate.
No
comments
were
received
on
the
burden
published
in
the
Federal
Register.

3(
d)
Effects
of
Less
Frequent
Collection
Less
frequent
information
collection
would
decrease
the
margin
of
assurance
that
facilities
are
continuing
to
meet
the
standards.
Requirements
for
information
gathering
and
recordkeeping
are
useful
techniques
to
ensure
that
good
operation
and
maintenance
practices
are
applied
and
emission
limitations
are
met.
If
the
information
required
by
these
standards
was
collected
less
frequently,
the
likelihood
of
detecting
poor
operation
and
maintenance
of
control
equipment
and
noncompliance
would
decrease.

General
Guidelines
None
of
these
reporting
or
recordkeeping
requirements
violate
any
of
the
regulations
established
by
OMB
at
5
CFR
1320.5.

3(
f)
Confidentiality
The
required
information
consists
of
emissions
data
and
other
information
that
have
been
determined
not
to
be
private.
However,
any
information
submitted
to
the
Agency
for
which
a
claim
of
confidentiality
is
made
will
be
safeguarded
according
to
the
Agency
policies

Collection
Methodology
and
Management
Following
notification
of
startup,
the
reviewing
authority
might
inspect
the
source
to
determine
whether
the
pollution
control
devices
are
properly
installed
and
operated.
Performance
test
reports
are
used
by
the
Agency
to
discern
a
source's
initial
capability
to
comply
with
the
emission
standard,
and
note
the
operating
conditions
under
which
compliance
was
achieved.
Data
and
records
maintained
by
the
respondents
are
tabulated
and
published
for
use
in
compliance
and
enforcement
programs.
The
semiannual
reports
are
used
for
problem
identification,
as
a
check
on
source
operation
and
maintenance,
and
for
compliance
determinations.

Information
contained
in
the
reports
is
entered
into
AFS
which
is
operated
and
maintained
by
EPA's
Office
of
Air
Quality
Planning
and
Standards.
AFS
is
EPA's
database
for
the
collection,
maintenance,
and
retrieval
of
compliance
and
annual
emission
inventory
data
for
over
100,000
industrial
and
government­
owned
facilities.
EPA
uses
AFS
for
tracking
air
pollution
compliance
and
enforcement
by
local
and
State
regulatory
agencies,
EPA
Regional
Offices
and
EPA
Headquarters.
EPA
and
its
delegated
Authorities
can
edit,
store,
retrieve
and
analyze
the
data.

The
records
required
by
this
regulation
must
be
retained
by
the
owner
or
operator
for
two
years.

5(
c)
Small
Entity
Flexibility
8
A
majority
of
the
affected
facilities
are
large
entities
(
e.
g.,
large
businesses).
However,
the
impact
on
small
entities
(
i.
e.,
small
businesses)
was
taken
into
consideration
during
the
development
of
the
regulation.
Due
to
technical
considerations
involving
the
process
operations
and
the
types
of
control
equipment
employed
,
the
recordkeeping
and
reporting
requirements
are
the
same
for
both
small
and
large
entities.
The
Agency
considers
these
requirements
the
minimum
needed
to
ensure
compliance
and,
therefore,
cannot
reduce
them
further
for
small
entities.
To
the
extent
that
larger
businesses
can
use
economies
of
scale
to
reduce
their
burden,
the
overall
burden
will
be
reduced.

documents
the
computation
of
individual
burdens
for
the
recordkeeping
and
reporting
requirements
applicable
to
the
industry
for
the
Subpart
included
in
this
ICR.
The
individual
burdens
are
expressed
under
standardized
headings
believed
to
be
consistent
with
the
concept
of
burden
under
the
Paperwork
Reduction
Act.
Where
appropriate,
specific
tasks
and
major
assumptions
have
been
identified.
Responses
to
this
information
collection
are
mandatory.

The
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.

Estimating
Respondent
Burden
The
average
annual
burden
to
industry
over
the
next
three
years
from
these
recordkeeping
and
reporting
requirements
is
estimated
to
be
4,524
labor
hours.
These
hours
are
based
on
Agency
studies
and
background
documents
from
the
development
of
the
regulation,
Agency
knowledge
and
experience
with
the
NESHAP
program,
the
previously

Maintenance
Costs
The
type
of
industry
costs
associated
with
the
information
collection
activity
in
the
regulations
are
labor
and
continuous
emissions
monitors
(
CEMs).
The
capital/
startup
costs
are
one
time
costs
when
a
facility
becomes
subject
to
the
regulation.
The
annual
operation
and
maintenance
costs
are
the
ongoing
costs
to
maintain
the
monitor
and
other
costs
such
as
photocopying
and
postage.

have
been
calculated
as
the
addition
of
the

The
average
annual
cost
for
capital/
startup
and
operation
and
maintenance
costs
to
industry
over
the
next
three
years
of
the
ICR
is
estimated
to
be
$
98,000.
This
cost
is

Estimating
Agency
Burden
and
Cost
10
The
only
costs
to
the
Agency
are
those
costs
associated
with
analysis
of
the
reported
information.
Publication
and
distribution
of
the
information
are
part
of
the
AFS
program.
Examination
of
records
to
be
maintained
by
the
respondents
will
occur
as
part
of
the
periodic
inspection
of
sources,
which
is
part
of
EPA's
overall
compliance
and
enforcement
program.

The
average
annual
Agency
cost
during
the
three
(
3)
years
of
the
ICR
is
estimated
to
be
$
5,975.
The
increase
in
agency
burden
hours
from
the
previous
ICR
is
due
to
an
omission
of
a
program
requirement
regarding
the
Agency
review
of
reports
on
estimated
arsenic
emission
rates.
This
cost
is
based
on
the
average
hourly
labor
rate
at
a
GS­
12,
Step
1,
times
a
1.6

multiplication
factor
to

Reasons
for
Change
in
Burden
The
decrease
in
industry
burden
hours
from
the
most
recently
approved
ICR
is
due
to
a
net
adjustment
decrease.
The
adjustment
decrease
in
burden
from
the
most
recently
approved
ICR
is
due
to
an
decrease
in
the
number
of
existing
sources.
The
decrease
in
the
number
of
existing
facilities
is
due
to
more
accurate
estimates
of
existing
and
anticipated
new
sources.
A
small
increase
is
realized
due
to
an
increase
in
the
annual
labor
cost
rate
from
the
previous
ICR.
