Short
Characterization/
Abstract
The
New
Source
Performance
Standards
(
NSPS)
for
the
regulations
published
at
40
CFR
part
60,
subpart
LL,
Metallic
Mineral
Processing
Plants,
were
proposed
on
August
24,
1982
and
promulgated
on
February
21,
1984.
These
regulations
apply
to
the
following
facilities
at
metallic
mineral
processing
plants:
each
crusher
and
screen
in
open­
pit
mines;
each
crusher,
screen,
bucket
elevator,
conveyor
belt
transfer
point,
thermal
dryer,
product
packaging
station,
storage
bin,
enclosed
storage
area,
truck
loading
and
unloading
station
at
the
mill
or
concentrator,
commencing
construction,
modification
or
reconstruction
after
the
date
of
proposal.
The
NSPS
does
not
apply
to
facilities
located
in
underground
mines,
or
to
facilities
performing
the
beneficiation
of
uranium
ore
at
uranium
ore
processing
plants,
commencing
construction,
modification
or
reconstruction
after
the
date
of
proposal.
This
information
is
being
collected
to
assure
compliance
with
40
CFR
part
60,
subpart
LL.

In
general,
all
NSPS
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
NSPS.

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
Agency
(
EPA)
Regional
Office.

Approximately
20
sources
are
currently
subject
to
the
regulation,
and
it
is
estimated
that
no
additional
sources
per
year
will
become
subject
to
the
regulation
in
the
next
three
years.
1
However,
we
estimate
that
one
(
1)
existing
source
per
year
will
reconstruct
or
make
a
physical
or
operational
change
such
that
they
will
be
required
to
submit
initial
notifications
and
conduct
an
2
initial
performance
test
to
demonstrate
compliance
with
this
standard.
The
total
industry
burden
hours
associated
with
this
subpart
is
estimated
to
be
2,306.
The
industry
cost
associated
with
this
subpart
is
estimated
to
be
$
186,140.

OMB
approved
the
currently
active
ICR
without
any
"
Terms
of
Clearance."

2.
Need
for
and
Use
of
the
Collection
2(
a)
Need/
Authority
for
the
Collection
The
Clean
Air
Act
(
Act)
provides
authority
to
the
Agency
to
establish
standards
to
control
air
pollution
and
to
ensure
compliance
with
promulgated
regulations
through
adequate
recordkeeping
and
reporting
by
the
affected
industries
(
i.
e.,
respondents).
The
regulations
include
the
New
Source
Performance
Standards
(
NSPS)
under
section
111
of
the
Act,
the
National
Emission
Standards
for
Hazardous
Air
Pollutants
(
NESHAP)
which
includes
the
original
NESHAP
standards
and
the
more
recent
Maximum
Achievable
Control
Technology
(
MACT)
or
NESHAP­
MACT
standards
under
section
112
of
the
Act,
and
emission
guidelines
for
the
designated
types
incinerators
under
section
129
of
the
Act.

2(
b)
Practical
Utility/
Users
of
the
Data
The
recordkeeping
and
reporting
requirements
in
the
standard(
s)
are
used
by
regulatory
agencies,
the
public
and
the
regulated
community
for
a
variety
of
reasons
including
the
determination
of
the
respondent's
compliance
status,
analytical
studies
to
demonstrate
compliance
trends,
and
evaluations
regarding
the
efficacy
of
the
promulgated
regulations.

The
required
recordkeeping
and
reporting
are
also
used
to:
1)
certify
compliance
with
the
regulations;
2)
determine
the
respondent's
compliance
with
the
designated
emission
limitation(
s);
3)
notify
regulatory
agencies
when
a
standard
is
violated;
4)
evaluate
continuous
compliance
through
the
use
of
emission
or
operational
parameter
monitors;
and
5)
ensure
that
plant
personnel
are
following
the
required
procedures
and
are
periodically
trained,
as
indicated.

3.
Nonduplication,
Consultations,
and
Other
Collection
Criteria
3(
a)
Nonduplication
The
standards
do
not
require
the
duplication
in
the
collection
and
reporting
of
information.
If
the
subject
standards
have
not
been
delegated,
the
information
is
sent
directly
to
the
appropriate
Environmental
Protection
Agency
(
EPA)
regional
office.
Otherwise,
the
information
is
sent
directly
to
the
delegated
state
or
local
agency.
If
a
state
or
local
agency
has
adopted
its
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.
3
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
December
1,
2004
(
69
FR
69909).
No
comments
were
received
on
the
burden
published
in
the
Federal
Register.

3(
c)
Consultations
Upon
review
of
the
standard,
information
available
and
the
data,
the
Agency
has
determined
the
recordkeeping
and
reporting
requirements
in
the
"
Active"
ICR
is
fully
supported
and
necessary
to
fulfil
the
requirements
of
the
Clean
Air
Act
(
CAA).
Any
pertinent
comments
received
since
the
last
ICR
renewal,
including
those
submitted
in
response
to
the
first
federal
register
notice
announcing
the
renewal
of
this
ICR,
have
been
reviewed,
and
it
has
been
determined
that
no
further
consultations
with
industry
are
necessary
to
calculate
the
burden
for
this
renewal.
It
should
be
noted
that
the
respondents,
the
industry
trade
association(
s)
and
other
interested
parties
were
provided
an
opportunity
to
comment
on
the
burden
associated
with
the
standard
as
it
was
being
developed.

3(
d)
Effects
of
Less
Frequent
Collection
The
effect
of
less
frequent
collection
would
be
a
decrease
in
the
margin
of
assurance
that
facilities
are
achieving
the
emission
reductions
mandated
by
the
CAA
through
the
promulgation
of
the
applicable
regulations.
In
addition,
the
likelihood
of
detecting
the
poor
operation
and
maintenance
of
control
equipment
decreases
and
the
detection
of
noncompliance
becomes
problematic.

3(
e)
General
Guidelines
Neither
the
reporting
nor
recordkeeping
requirements
violate
the
regulations
established
by
Office
of
Management
and
Budget
(
OMB)
at
5
CFR
part
1320,
Section
1320.5.
However,
most
NESHAP
standards
and
a
few
NSPS
standards
require
records
to
be
kept
more
than
three
years.
In
general,
these
standards
require
the
respondents
to
maintain
all
records,
including
reports
and
notifications,
for
five
years.
The
five­
year
record
retention
requirement
is
consistent
with
the
permit
program
at
40
CFR
part
70,
and
the
five­
year
statute
of
limitations
on
which
the
permit
program
is
based.

The
retention
of
records
for
five
years
allows
EPA
to
establish
the
compliance
history
of
the
respondent
for
purposes
of
determining
the
appropriate
level
of
enforcement
action.
Historically,
EPA
notes
that
the
most
flagrant
violations
have
extended
beyond
a
five­
year
period.
If
records
are
retained
for
less
than
five
years,
EPA
would
be
deterred
from
pursuing
the
most
flagrant
violations
due
to
the
destruction
of
records
documenting
noncompliance.

3(

Any
information
submitted
to
the
Agency
for
which
a
claim
of
confidentiality
is
made
will
be
safeguarded
according
to
the
Agency
policies
set
forth
in

Electronic
Reporting
At
the
present,
many
respondents
to
CAA
standards
use
monitoring
equipment
that
automatically
records
parameter
data.
Although
personnel
at
the
affected
facility
must
evaluate
the
data,
this
internal
automation
has
significantly
reduced
the
burden
associated
with
monitoring
and
recordkeeping
at
the
plant
site.

Also
regulatory
agencies,
in
cooperation
with
the
respondents,
continue
to
create
reporting
systems
to
transmit
data
electronically.
However,
electronic
reporting
systems
are
still
not
widely
used.
At
this
time,
it
is
estimated
that
approximately
10
percent
of
the
respondents
use
electronic
reporting.

review
of
compliance
monitoring
records
and
reports.
Evaluation
reports
and
inspection
results
are
maintained
by
the
Agency

costs
are
estimated
to
be
the

previous
ICR
due
to
the
assumption
that
inflation
will
be
minimal
over
the
next
three
years.

The
total

for
this
ICR
is
the
total

Estimating
Agency
Burden
and
Costs
The
only
costs
to
the
Agency
are
those
associated
with
analysis
of
the
reported
information.
EPA's
overall
compliance
and
enforcement
program
includes
activities
such
as
the
examination
of
records
maintained
by
the
respondents
and
the
publication
and
distribution
of
collected
information.

The
average
annual
Agency
cost
during
the
three
years
of
the
ICR
is
shown
in
Table
2,
attached.

This
cost
is
based
on
the
average
hourly
labor
rate
as
follows:

Managerial
$
56.02
(
GS­
13,
Step
5,
$
35.01
x
1.6)
Technical
$
41.57
(

$
25.98
x
1.6)
Clerical
$
22.50
(
GS­
6,
Step

$
14.06
x
1.6)

These
rates
are
from
the
Office
of
Personnel
Management
(
OPM)
"
2005
General
Schedule"
which
excludes
locality
rates
of
pay.

f)
Reasons
for
Change
in
Burden
The
increase
in
burden
from
the
most
recently
approved
ICR
is
due
to
an
adjustment.
The
adjustment
increase
in
burden
from
the
most
recently
approved
ICR
is
due
in
part
to
an
increase
in
the
number
of
modified
sources.
In
the
previous
ICR
we
assumed
that
there
would
be
no
reconstructed
or
modified
plants.
However,
in
this
ICR
we
assume
that
at
least
one
(
1)
plant
will
undergo
a
reconstruction
or
modification
such
that
the
plant
will
be
required
to
submit
initial
notifications
and
conduct
an
initial
performance
test.
The
increase
in
burden
is
also
due
to
a
change
in
the
method
in
which
we
calculated
the
burden
hours.
In
the
previous
ICR,
we
only
accounted
for
burden
hours
associated
with
technical
personnel.
In
this
ICR
we
have
also
included
burden
hours
for
management
and
clerical
personnel.

6(
g)
Burden
Statement
The
annual
public
reporting
and
recordkeeping
burden
for
this
collection
of
information
is
estimated
to
average
52
hours
per
response.
Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
persons
to
generate,
maintain,
retain,
disclose,
or
provide
information
to
or
for
a
Federal
agency.
This
includes
the
time
needed
to
review
instructions;
to
develop,
acquire,
install,
and
utilize
technology
and
systems
for
the
purposes
of
collecting,
validating
and
verifying
information,
processing
and
maintaining
information,
and
disclosing
and
providing
information;
to
adjust
the
existing
ways
to
comply
with
any
previously
applicable
instructions
and
requirements;
to
train
personnel
to
be
able
to
respond
to
a
collection
of
information;
to
search
data
sources;
to
complete
and
review
the
collection
of
information;
and
to
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
valid
OMB
Control
Number.

OMB
Control
Numbers
for
EPA's
