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
22
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.
The
total
industry
burden
hours
associated
with
this
subpart
is
estimated
to
be
1,760.
The
industry
cost
associated
with
this
subpart
is
estimated
to
be
$
97,398.40.

2.
Need
for
and
Use
of
the
Collection
2(
a)
Need/
Authority
for
the
Collection
The
EPA
is
charged
under
Section
111
of
the
Clean
Air
Act
(
CAA),
as
amended,
to
2
establish
standards
of
performance
for
new
stationary
sources
that
reflect:

...
application
of
the
best
technological
system
of
continuous
emissions
reduction
which
(
taking
into
consideration
the
cost
of
achieving
such
emissions
reduction,
or
any
non­
air
quality
health
and
environmental
impact
and
energy
requirements)
the
Administrator
determines
has
been
adequately
demonstrated.
Section
111(
a)(
l).

The
Agency
refers
to
this
charge
as
selecting
the
best
demonstrated
technology
(
BDT).
Section
111
also
requires
that
the
Administrator
review
and,
if
appropriate,
revise
such
standards
every
four
years.

In
the
Administrator's
judgment,
particulate
matter
from
metallic
mineral
processing
plants
cause
or
contribute
to
air
pollution
that
may
reasonably
be
anticipated
to
endanger
public
health
or
welfare.
Therefore,
NSPS
were
promulgated
for
this
source
category
at
40
CFR
Part
60,
Subpart
LL.

2(
b)
Practical
Utility/
Users
of
the
Data
The
control
of
emissions
of
particulate
matter
from
metallic
mineral
processing
plants
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
Emissions
of
particulate
matter
from
metallic
mineral
processing
plants
are
the
result
of
operation
of
the
affected
facilities.
The
subject
standards
are
achieved
by
the
capture
of
particulate
matter
emissions
using
a
baghouse
or
wet
scrubber.
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,
i.
e.,
temperature,
pressure,
flow
rate,
under
which
compliance
was
achieved.
The
semiannual
reports
are
used
for
problem
identification,
as
a
check
on
source
operation
and
maintenance,
and
for
compliance
determinations.
Adequate
monitoring,
recordkeeping,
and
reporting
are
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
is
required
under
40
CFR
Part
60,
Subpart
LL.

3(
a)
Nonduplication
3
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,(
66FR54514).
No
comments
were
received
on
the
burden
published
in
the
Federal
Register.

3(
c)
Consultations
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.

3(
e)
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

are
used
by
the
Agency
to
discern
a
source's
initial
capability
to
comply
with
the
emission
standard,
and
note
the

Estimating
Respondent
Burden
The
average
annual
burden
to
industry
over
the
next
three
years
from
these
recordkeeping
and
reporting
requirements
is
estimated
to
be
1,760
(
Total
Labor

These
hours
are
based
on
Agency
studies
and
background
documents
from
the
development
of
the
regulation,
Agency
knowledge
and
experience
with

Estimating
Labor
Costs
This
ICR
uses
a
Technical
Labor
Rate
of
$
55.34
per
hour.
This
rate
is
from
the
United

The
rate
is
from
column

The
wage
rate
has
been
increased
by
110%
to
account
for
the
benefit
packages
available
to
those
employed
by
private

Costs
The
type
of
industry
costs
associated
with
the
information
collection
activity
in
the
regulations
are
the
continuous
monitoring
devices
associated
with
the
wet

The
capital/
startup
costs
are
one
time
costs
when
a
facility
becomes
subject
to
the
regulation.
The
9
annual
operation

Estimating
Agency
Burden
and
Cost
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
3
years
of
the
ICR
is
estimated
to
be
10
$
6,740.80.
[
See
Table
1
in
Section
6(
e)].
This
cost
is
based
on
the
average
hourly
labor
rate
at
a
GS­
12,
Step
1,
times
a
1.6
benefits
multiplication
factor
to
account
for
government
overhead
expenses
for
a
total
of
$
38.30.

These
rates
are
from
the
Office
of
Planning
and
Management's
(
OPM)
"
2002
General
Schedule"
which
excludes
locality
rates
of
pay.

f)
Reasons
for
Change
in
Burden
Although
there
have
been
changes
in
ownership
and
consolidation
within
the
industry,
the
estimated
number
of
facilities
subject
to
this
subpart
has
not
changed
from
the
previous
ICR.
In
addition,
we
do
not
expect
any
growth
in
the
industry
over
the
next
three
years.
Therefore,
the
estimated
number
of
burden
hours
on
industry
for
the
next
three
years
will
not
change
from
the
11
previous
ICR.

When
estimating
labor
costs,
the
previous
ICR
did
not
include
the
costs
associated
with
benefit
packages
available
to
private
industry
employees.
To
account
for
these
benefits
in
estimating
labor
costs,
the
estimated
hourly
rate
increased
from
$
23.80
to
$
55.34.
This
resulted
in
an
overall
increase
in
the
annual
industry
cost
burden
from
$
41,888.00
to
$
97,398.40.
A
slight
increase
in
the
federal
employee
pay
scale
also
increased
the
annual
cost
burden
on
the
federal
government
from
$
6,582.40
to
$
6,740.80.

Burden
Statement
Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
persons
to
generate,
maintain,
retain,
or
disclose
or
provide
information
to
or
for
a
Federal
agency.
This
includes
the
time
needed
to
review
instructions;
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;
adjust
the
existing
ways
to
comply
with
any
previously
applicable

collection
of
information;
search
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
