Short
Characterization/
Abstract
The
New
Source
Performance
Standards
(
NSPS)
for
Nonmetallic
Mineral
Processing
Plants
were
proposed
on
August
31,
1983
and
promulgated
on
August
1,
1985.
These
standards
apply
to
the
following
affected
facilities
in
fixed
or
portable
nonmetallic
mineral
processing
plants:

each
crusher,
grinding
mill,
screening
operation,
bucket
elevator,
belt
conveyor,
bagging
operation,
storage
bin,
enclosed
truck
or
railcar
loading
station,
which
commenced
construction,

modification
or
reconstruction
after
August
31,
1983.
Also,
crushers
and
grinding
mills
at
hot
mix
asphalt
facilities
that
reduce
the
size
of
nonmetallic
minerals
embedded
in
recycled
asphalt
pavement
and
subsequent
affected
facilities
up
to,
but
not
including,
the
first
storage
silo
or
bin
1
We
are
assuming
that
the
number
of
facilities
currently
using
wet
scrubbers
is
negligible;
thus
for
the
purpose
of
this
ICR
no
facilities
will
be
subject
to
the
burden
associated
with
reporting
requirements
specific
to
wet
scrubbers.

are
subject
to
the
provisions
of
the
subpart.
The
provisions
of
this
subpart
do
not
apply
to
the
following
operations:
all
facilities
located
in
underground
mines;
and
stand­
alone
screening
operations
at
plants
without
crushers
or
grinding
mills.
An
affected
facility
that
is
subject
to
the
provisions
of
subparts
F
or
I
or
that
follows
in
the
process
any
facility
subject
to
the
provisions
of
subparts
F
or
I
of
this
part
is
not
subject
to
the
provisions
of
this
part.
In
addition
the
following
plants
are
not
subject
to
this
subpart:
fixed
sand
and
gravel
plants
and
crushed
stone
plants
with
capacities
of
23
megagrams
per
hour
(
25
tons
per
hour)
or
less;
portable
sand
and
gravel
plants
and
crushed
stone
plants
with
capacities
of
136
megagrams
per
hour
(
150
tons
per
hour)
or
less;

common
clay
plants
and
pumice
plants
with
capacities
of
9
megagrams
per
hour
(
10
tons
per
hour)
or
less.
The
purpose
of
this
NSPS
is
to
control
the
emissions
of
particulate
matter
from
nonmetallic
mineral
processing
plants.
The
standards
limit
particulate
emissions
to
0.05
g/
dscm,

and
limit
opacity
to
7%
when
exiting
from
a
dry
emission
control
device.
This
information
is
being
collected
to
assure
compliance
with
40
CFR
Part
60
Subpart
OOO.

There
are
three
types
of
reporting
requirements
for
owners
or
operators
of
facilities
under
this
NSPS;
1)
notifications
(
e.
g.,
notice
for
actual
startup,
initial
performance
test,
and
equipment
replacement);
2)
a
report
on
the
results
of
the
performance
test;
and
3)
for
wet
scrubber
operations,
daily
measurements
of
both
change
in
pressure
of
the
gas
stream
across
the
scrubber
and
the
scrubbing
liquid
flow
rate,
and
semiannual
reports
for
deviations
(+/­
30%)
from
the
performance
test1.
The
purpose
of
the
notifications
are
to
inform
the
Agency
or
delegated
authority
when
a
source
becomes
subject
to
this
standard.
Performance
tests
are
conducted
to
2
As
mentioned
in
1(
b),
a
facility
is
defined
as
each
individual
piece
of
operating
equipment,
not
an
entire
plant;
thus
it
is
estimated
that
580
pieces
of
equipment
will
either
be
constructed
or
modified
such
that
580
plants
will
be
required
to
meet
the
reporting
and
recordkeeping
requirements
of
this
subpart.

ensure
that
the
new
plants
operate
within
the
boundaries
outlined
in
the
standard.
The
semiannual
reports
are
used
for
problem
identification,
as
a
check
on
source
operation
and
maintenance,
and
for
compliance
determinations.
Under
this
standard
the
data
collected
by
the
affected
industry
is
retained
at
the
facility
for
a
minimum
of
two
years
and
made
available
for
inspection
by
the
Administrator.

All
notifications
and
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
EPA
Regional
Office.

The
Agency
or
delegated
State
or
local
authority
will
use
this
information
to
ensure
that
compliance
with
the
NSPS
is
achieved
and
maintained
by
new,
modified,
or
reconstructed
sources
subject
to
the
regulations.
In
the
absence
of
this
information,
compliance
with
the
standards
could
be
ensured
only
through
continuous
on­
site
inspections
by
regulatory
agency
personnel.

Consequently,
not
collecting
the
information
would
result
in
either
greatly
increased
expenditures
of
resources,
or
the
inability
to
ensure
compliance
with
the
standards.

It
is
estimated
that
there
are
approximately
3,725
nonmetallic
mineral
processing
plants
in
the
United
States
that
are
subject
to
this
NSPS.
In
addition,
it
is
estimated
that
580
additional
plants
will
become
subject
to
the
standard
each
year
over
the
next
three
years2.
Based
on
this
information,
the
cost
burden
of
this
ICR
on
the
nonmetallic
mineral
processing
industry
will
be
$
1,744,097.77
(
See
Table

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,
as
amended,
to
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
nonair
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
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
or
methods
(
in
accordance
with
such
methods
at
such
locations,
at
such
intervals,
and
in
such
manner
as
the
Administrator
shall
prescribe);
(
D)

sample
such
emissions;
(
E)
keep
records
on
control
equipment
parameters,
production
variables
or
other
indirect
data
when
direct
monitoring
of
emissions
is
impractical;
(
F)
submit
compliance
certifications;
and
(
G)
provide
such
other
information
as
he
may
reasonably
require.
5
In
the
Administrator's
judgment,
particulate
emissions
from
nonmetallic
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
OOO.

2(
b)
PRACTICAL
UTILITY/
USERS
OF
THE
DATA
The
control
of
emissions
of
particulates
from
nonmetallic
mineral
processing
plants
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
Emissions
of
particulates
from
nonmetallic
mineral
processing
plants
are
the
result
of
the
operation
of
each
crusher,
grinding
mill,
screening
operation,
bucket
elevator,
belt
conveyor,
bagging
operation,
storage
bin,
enclosed
truck
or
railcar
loading
station
at
nonmetallic
minerals
processing
plants.
Monitoring
requirements
specific
to
nonmetallic
mineral
processing
plants
provide
information
on
opacity.
Owners
or
operators
are
also
required
to
conduct
a
one­
time
performance
test
on
each
affected
piece
of
equipment
using
EPA
Methods
5
and
9
to
test
particulates
and
opacity.
Owners
or
operators
of
affected
facilities
using
a
wet
scrubber
emission
control
device
shall
instead
install,
calibrate,
maintain,
and
operate
a
continuous
monitoring
device
which
monitors
the
pressure
loss
of
the
gas
stream
through
the
scrubber,
and
a
continuous
monitoring
device
which
monitors
the
scrubbing
liquid
supply
pressure
to
the
control
device.

The
required
notifications
are
used
to
inform
the
Agency
or
delegated
authority
when
a
source
becomes
subject
to
the
standard.
The
reviewing
authority
may
then
inspect
the
source
to
check
if
the
pollution
control
devices
are
properly
installed
and
operated
and
the
standard
is
6
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
standard,
and
serve
as
a
record
of
the
operating
conditions
under
which
compliance
was
achieved.

3.
Nonduplication,
Consultations,
and
Other
Collection
Criteria
3(
a)
Nonduplication
The
recordkeeping
and
reporting
requested
is
required
under
40
CFR
Part
60
Subpart
OOO.
If
the
standard
has
not
been
delegated
the
information
is
sent
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
regulation
to
implement
the
Federal
Regulation,
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
Standard.
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,
1999.

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
7
facilities
are
continuing
to
meet
the
required
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

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
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.

Information
contained
in
the
reports
is
entered
into
AIRS
which
is
operated
and
maintained
by
EPA's
Office
of
Air
Quality
Planning
and
Standards.
AIRS
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
AIRS
for
tracking
air
pollution
compliance
and
enforcement
by
Local
and
State
regulatory
agencies,
and
EPA
Regional
Offices
and
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.

Small
Entity
Flexibility
The
recordkeeping
and
reporting
requirements
were
selected
within
the
context
of
this
specific
subpart
and
the
specific
process
equipment
and
pollutants.
The
impact
on
small
businesses
was
accounted
for
in
the
regulation
development.
The
requirements
reflect
the
burden
on
small
businesses.
Even
though,
the
recordkeeping
and
reporting
requirements
are
the
same
for
small
and
larger
businesses.
To
the
extent
that
larger
businesses
can
use
economies
of
scale
to
reduce
their
burden,
the
overall
burden
will
be
reduced.
The
Agency
considers
these
requirements
the
minimum
needed
to
ensure
compliance
and,
therefore,
cannot
reduce
them
further
for
small
businesses.

As
mentioned
earlier,
the

is
negligible.
Thus

are
estimated
to
be
zero.

The
average
annual

to
industry
over
the
next
three
years
from
these
recordkeeping

requirements
is
estimated
at
31,746

(
See
Table

These
hours
are
based
on
Agency

associated
with

of
the
reported

Publication
and
distribution
of
the
information
are
part
of
the
AIRS

Examination
of
records
to
be
maintained
by
the

will
occur
as
part
of
the
periodic
inspection
of
sources,
which
is
part
of
EPA's
overall
compliance
and
enforcement
program.
The
average
annual
Federal
Government
cost
during
the
3
years
of
the
ICR
is
estimated
to
be
$
1,439,448.16
per
year
(
See
Table

This
cost
is
based
on
a
federal
government
employee
salary
at
the

plus
110%

which
is
equal

NSA
estimates
that
approximately
60%

NSA
also
estimates
that
approximately
25%

Therefore,
it
is

Reasons
for
Change
in
Burden
The
primary
sources
used
to
estimate
the
number
of
facilities
subject
to
this
NSPS
and
the
associated
growth
rate
for
the
next
three
years
were
the
National
Stone
Association
and
expert
staff
from
Luck
Stone,
Inc.
5
Using
an
estimate
of
3,725
facilities
currently
subject
to
this
NSPS
and
a
growth
rate
of
580
facility
per
year
for
the
next
three
years,
the
cost
of
this
NSPS
on
the
nonmetallic
mineral
processing
industry
will
be
approximately
$
1,744,097.77.6
The
estimated
number
of
existing
nonmetallic
mineral
processing
facilities
subject
to
this
subpart
has
increased
from
the
previous
ICR
because
of
better
data
regarding
the
number
of
sources
subject
to
this
NSPS.
In
particular,
more
accurate
information
has
become
available
regarding
the
number
of
existing
sand
and
gravel
operations.
7
The
growth
rate
of
580
facilities
per
year
is
also
much
higher
than
what
was
estimated
in
the
previous
ICR.
We
attribute
this
increase
in
growth
to
a
strong
economy
including
significant
8
On
June
9,
1998,
the
President
signed
into
law
PL
105­
178,
the
Transportation
Equity
Act
for
the
21st
Century
(
TEA­
21)
authorizing
highway,
highway
safety,
transit
and
other
surface
transportation
programs
for
the
next
6
years.
The
full
authorizations
for
the
highway
(
including
highway
safety)
and
transit
programs
in
TEA­
21
total
almost
$
218
billion.
The
nonmetallic
mineral
processing
industry
is
anticipating
an
increase
in
demand
once
funds
from
TEA­
21
are
made
available
for
roadway
projects;
thus
we
are
predicting
an
increase
in
the
number
of
facilities
upgrading
or
modifying
in
an
effort
to
increase
capacity.

9
We
estimated
the
growth
of
new
facilities
as
0.5%
of
the
number
of
existing
facilities.
This
is
due
to
the
fact
that
permitting
new
nonmetallic
mineral
processing
facilities,
including
sand
and
gravel
facilities,
is
uncommon.

10
We
estimated
that
approximately
1%
of
the
sand
and
gravel
facilities
not
previously
subject
(
50)
and
approximately
10%
of
the
stone
quarries
not
previously
subject
(
140)
will
undergo
a
modification
making
them
subject
to
this
subpart.
Note
that
a
smaller
percentage
of
sand
and
gravel
facilities
was
estimated
since
these
plants
are
less
likely
to
utilize
crushers
on­
site
in
comparison
to
stone
quarry
operations.

11
We
estimated
that
approximately
10%
of
the
3,725
plants
currently
subject
to
the
rule
will
undergo
a
facility
modification
that
will
subject
the
facility
to
the
reporting
and
recordkeeping
requirements
of

subpart.

Our
growth
rate
estimates
are
also
the
result
of
a
more
comprehensive
analysis
of
the
affected
facilities.
Our
analysis
of
the

for

considered
three
categories
of
facilities
potentially
subject
to
this
rule.

The
formula
used
to
calculate
labor
rates
on
the
previous
ICR
for
Subpart
OOO
has
been
replaced
by
the
rates
identified
by
the
Bureau
of
Labor
Statistics12.
Using
a
technical
labor
rate
of
$
54.94,
the
estimated
total
cost
of
this
NSPS
on
the
nonmetallic
mineral
processing
industry
is
$
1,744,097.77,
approximately
$
1,526,994
more
than
the
total
cost
burden
on
the
nonmetallic
mineral
processing
industry
estimated
by
the
previous
ICR.

The
primary
reason
for
the
increased
Agency
burden
is
also
due
to
the
change
in
the
number
of
existing
facilities
subject
to
this
subpart
as
well
as
the
increased
number
of
new
facilities
that
are
expected
to
become
subject
to
this
subpart
over
the
next
three
years.
The
overall
burden
as
a
result
of
the
increase
in
the
number
of
new
facilities
subject
to
the
rule
is
approximately
$
1,510,649.
