Short
Characterization/
Abstract
This
information
is
being
collected
to
assure
compliance
with
40
CFR
Part
60,
Subpart
Db.
Sulfur
dioxide
(
SO
2),
particulate
matter
(
PM),
and
nitrogen
oxides
(
NO
x)
are
the
pollutants
regulated
under
this
Subpart.
The
rule
governing
SO
2
emissions
was
promulgated
on
December
16,
1987
(
52
FR
47842),
and
the
rule
governing
PM
and
NO
x
was
promulgated
on
November
25,

1986
(
51
FR
42768).
Revisions
to
the
NO
x
standards
were
promulgated
on
December
18,
1989
(
54
FR
51825).
These
standards
apply
to
the
following
facilities:
industrial­

commercialinstitutional
steam
generating
units
that
commenced
construction,
modification,
or
reconstruction
after
June
19,
1984,
and
that
have
a
heat
input
capacity
from
fuels
combusted
in
the
unit
of
greater
than
29
MW
(
100
million
Btu/
hour).

Owners
or
operators
of
the
affected
facilities
described
must
make
one­
time­
only
notifications,
and
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
these
standards
2
provide
information
on
compliance
with
the
emission
limits.
Quarterly
reports
of
excess
emissions,
or
semiannual
reports
of
no
excess
emissions,
are
required.
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.
A
file
of
these
reports
and
all
other
required
records
shall
be
retained
for
at
least
2
years.

Approximately
870
sources
are
currently
subject
to
the
standard,
and
it
is
estimated
that
an
additional
58
sources
per
year
will
become
subject
to
the
standard
in
the
next
three
years.
The
cost
of
this
ICR
will
be
$
13,777,791
per
year.

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
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
3
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,
PM,
and
NO
x
emissions
from
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
Db.

2(
b)
Practical
Utility/
Users
of
the
Data
The
control
of
emissions
of
SO
2,
PM,
and
NO
x
from
steam
generating
units
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
These
emissions
from
steam
generating
units
are
the
result
of
operation
of
the
boilers
and
the
fuel
they
fire.
The
standards
rely
on
the
capture
and/
or
reduction
of
SO
2,
PM,
and
NO
x
emissions
by
adsorption,
absorption,
condensation,
combustion,
or
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
4
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.
Data
and
records
maintained
by
the
respondents
are
tabulated
and
published
for
use
in
compliance
and
enforcement
programs.
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
3(
a)
Nonduplication
The
recordkeeping
and
reporting
requested
is
required
under
40
CFR
Part
60,
Subpart
Db.
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
June
4,
1999.

3(
c)
Consultations
No
comments
were
received
on
the
burden
published
in
the
Federal
Register.

3(
d)
Effects
of
Less
Frequent
Collection
5
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

Estimating
Respondent
Burden
The
average
annual
burden
to
industry
over
the
next
three
years
from
these
recordkeeping
and
reporting
requirements
is
estimated
at
575,033
person­
hours.
These
hours
are
based
on
10
Agency
studies
and
background
documents
from
the
development
of
the
standards
or
test
methods,
Agency
knowledge
and
experience
with

Estimating
Respondent
Costs
(
i)
Estimating
Labor
Costs
This
ICR
uses
a
labor
rate
of
$
23.96
per
hour
from
the
United
States
Department
of
Commerce
Bureau
of
Labor
Statistics,
March
1998,
Table
2
(
employment
costs
for
civilian
workers,
by
occupational
and
industry
group).
The
rate
is
for
the
Technical
occupational
group,

and
from
column

("
Total
compensation").

(

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
$
11,600,000,

based
on
58
new
sources
per
year
multiplied
by
$
200,000
per
CEM.
The
annual
operations
and
maintenance
(
O&
M)
costs
are
$
14,355,000,
based
on
an
average
of
957
existing
sources
(
over
the
3
years)
multiplied
by
$
15,000
for
upkeep
of
a
monitoring
device.
The
total
respondent
costs
have
been
calculated
as
the
sum
of
the
capital
start
up
costs
and
the
annual
O&
M
costs.

Therefore,
the
average
total
annual
respondent
burden
for
capital
and
O&
M
costs
to
industry
over
the
next
three
years
of
the
ICR
is
estimated
to
be
$
25,955,000.

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
Federal
Government
cost
during
the
3
years
of
the
ICR
is
estimated
to
be
$
47,354,681.
This
cost
is
based
on
the
average
wage
of
a
GS10
step
1
employee,
and
travel
associated
with
compliance
activities.
Details
of
the
basis
for
this
estimate
are
in
Table

Estimating
the
Respondent
Universe
and
Total
Burden
and
Costs
The
number
of
existing
sources
subject
to
NSPS
Subpart
Db
is
870,
and
the
number
of
new
sources
subject
is
58
per
year.
The
total
annual
labor
costs
are
$
13,777,791,
and
total
annual
capital
and
O&
M
costs
to
the
regulated
entity
are
$
25,955,000.
Details
upon
which
this
estimate
is
based
appear
in
Table

6(

Reasons
for
Change
in
Burden
The
increase
in
burden
from
the
most
recently
approved
ICR
is
due
to
an
increase
in
the
number
of
new
or
modified
sources,
and
to
the
addition
of
capital
and
O&
M
costs
for
the
CEMs.

The
capital
and
O&
M
costs
are
not
new,
but
simply
had
not
been
previously
reflected.
The
more
accurate
cost
for
CEM
was
obtained
from
the
Office
of
Air
Quality
and
Planning
Standards.
The
figures
are
more
accurate
and
up
to
date
because
the
EPA
received
the
cost
information
from
the
CEM
manufacturers.
