Short
Characterization/
Abstract
The
New
Source
Performance
Standards
(
NSPS)
for
Small
Industrial­
commercial­

Institutional
Steam
Generating
Units
were
proposed
on
June
9,
1989
and
promulgated
on
September
12,
1990.
These
standards
apply
to
the
following
facilities
in
small
industrialcommercial
institutional
steam
generating
units
with
maximum
design
heat
input
capacity
of
29
megawatt
(
MW)
(
100
million
Btu/
hr)
or
less,
but
greater
than
or
equal
to
2.9
MW
(
10
million
Btu/
hr)
commencing
construction,
modification
or
construction
after
June
9,
1989.
The
standards
limit
the
emissions
the
Sulfur
Dioxide
(
SO
2)
and
Particulate
Matter
(
PM).
This
information
is
being
collected
to
assure
compliance
with
40
CFR
Part
60,
Subpart
Dc.

Owners
or
operators
of
the
affected
facilities
described
must
make
one­
time­
only
notifications.
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.
Monitoring
requirements
specific
to
small
industrial­
commercial­
institutional
steam
generating
units
provide
information
on
the
operation
of
the
emissions
control
device
and
compliance
with
SO
2
and
PM
standards.
Quarterly
or
Semiannual
reports
of
excess
emissions
are
required.
These
notifications,
reports,
and
records
are
essential
in
determining
compliance;
and
are
required,
in
general,
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
2
years
following
the
date
of
such
measurement,

maintenance
reports
and
records.

Approximately
638
sources
are
currently
subject
to
the
standard,
and
it
is
estimated
that
an
additional
70
sources
per
year
will
become
subject
to
the
standard
in
the
next
three
years.
The
cost
of
this
ICR
will
be
$
16,899,488
dollars.
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
EPA
Regional
Office.

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,
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
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
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),
and
(
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.

In
the
Administrator's
judgment,
SO
2
and
PM
emissions
from
Small
Industrial­

Commercial­
Institutional
Steam
Generating
Units
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
Dc
2(
b)
PRACTICAL
UTILITY/
USERS
OF
THE
DATA
The
control
of
emissions
of
SO
2
and
PM
from
Small
Industrial­
Commercial­
Institutional
Steam
Generating
Units
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
Emissions
of
SO
2
and
PM
from
Small
Industrial­
Commercial­
Institutional
Steam
Generating
Units
are
the
result
of
operation
of
the
boilers
and
the
fuel
they
fire.
These
standards
rely
on
the
capture/
reduction
of
SO
2
and
PM
emissions
by
the
use
of
control
technologies
such
as
settling
chambers,
cyclones,
wet
collectors,

electrostatic
precipitators,
and
fabric
filters.

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
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.
The
quarterly/
semiannual
reports
are
used
for
problem
identification,
as
a
check
on
source
operation
and
maintenance,
and
for
compliance
determinations.

3.
Nonduplication,
Consultations,
and
Other
Collection
Criteria
3(
a)
Nonduplication
The
recordkeeping
and
reporting
requested
is
required
under
40
CFR
Part
60
Subpart
Dc.
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
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
of
the
reporting
or
recordkeeping
requirements
contained
in
40
CFR

data
and
other
information
that
have
been
determined
not
to
be
private.
However,
any

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
quarterly
and/
or
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
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.

5(
c)
Small
Entity
Flexibility
The
recordkeeping
and
reporting
requirements
were
selected
within
the
context
of
this
specific
subpart
and
the
specific
process
equipment
and
pollutant(
s).)
The
requirements
reflect
the
burden
on
small
businesses.
To
the
extent
that
larger
businesses
can
use
economies
of
scale
to
reduce
their
burden,
the
overall
burden
will
be
reduced.
Although
the
recordkeeping
and
reporting
requirements
are
the
same
for
small
and
larger
businesses,
the
Agency
considers
these
requirements
the
minimum
needed
to
ensure
compliance
and,
therefore,
cannot
reduce
them
further
for
small
businesses.

Schedule
The
specific
frequency

the
computation
of
individual
burdens
for
each
of
the

reporting
requirements
applicable
to
the

The
individual
burdens
are
expressed
under
standardized
headings
believed
to
be
consistent
with
the
concept
of

Where
appropriate,
specific
tasks
and
major
assumptions
have
been
identified.

Responses
to
this

are
mandatory.
The
Agency
may
not
conduct

and
a
person
is
not
required
to
respond
to,
a

of
information
unless
it
displays
a
currently
valid

Estimating
Respondent
Burden
The
average
annual
burden
to
industry
over
the
next
three
years
from
these
recordkeeping
and
reporting
requirements
is
estimated
at
306,727
person­
hours.
These
hours
are
based
on
Agency
studies
and
background
documents
from
the
development
of
the
standards
or
test
methods,
Agency
knowledge
and
experience
with
the

uses
labor
rates
of
$

for
technical
and
$
24.42
for
non­
technical
from
the
United

Estimating
Capital
and
Operations
and
Maintenance
Costs
The
type
of
industry
costs
associated
with
the
information
collection
activity
in
the
standards
are
labor
and
CEMs.
The
capital
start
up
costs
are
one
time
costs
when
a
facility
becomes
subject
to
the
standard.
The
capital
start
up
costs
for
this
regulation
are
$
8,400,000.

This
is
based
on
56
new
sources
(
80
percent
of
the
new
source
will
use
a
fuel
that
will
require
CEM)
per
year
multiplied
by
$
150,000
per
CEM.
The
annual
operations
and
maintenance
costs
are
$
4,785,000.
This
is
based
on
319
existing
sources
that
is
required
to
install
CEM
multiplied
by
$
15,000
for
upkeep
of
the
monitoring
device.
The
total
respondent
costs
have
been
calculated
on
the
addition
of
the
capital
start
up
costs
and
the
annual
operations
and
maintenance
costs.
The
average
annual
burden
for
capital
and
operations
and
maintenance
costs
to
industry
over
the
next
three
years
of
the
ICR
is
estimated
to
be
