Short
Characterization/
Abstract
The
New
Source
Performance
Standards
(
NSPS)
for
Subpart
Ka
was
proposed
on
May
18,
1978
and
promulgated
on
April
4,
1980.
These
standards
apply
to
the
following
facilities
in
Subpart
Ka:
Storage
Vessels
of
petroleum
liquids
which
has
a
storage
capacity
greater
than
151,416
(
40,000
gallons),
and
for
which
construction,

reconstruction
or
modification
commenced
after
May
18,
1978
and
prior
to
July
23,

1984.

Owners
or
operators
of
the
affected
facilities
described
must
make
one­
time­
only
notifications
including:
notification
of
any
physical
or
operational
change
to
an
existing
facility
which
may
increase
the
regulated
pollutant
emission
rate,
notification
of
the
initial
performance
test;
including
information
necessary
to
determine
the
conditions
of
2
the
performance
test,
and
performance
test
measurements
and
results.
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.
Measuring
requirements
specific
to
NSPS
Subpart
Ka
provide
information
on
the
operation
of
the
emissions
control
devices.
These
notifications,
reports
and
records
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
two
years.
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.

Prior
to
January
19,
2001,
approximately
174
respondents
were
subject
to
the
NSPS
Subpart
Ka.
After
that
time,
OMB
approved
the
Consolidated
Air
Rule
for
the
SOCMI
Industry.
It
is
estimated
that
10%
of
the
174
respondents
will
take
advantage
of
the
new
Rule.
The
number
of
respondents
expected
to
adhere
to
NSPS
Subpart
Ka
is
157.
No
new
sources
are
expected
to
become
subject
to
NSPS
Subpart
Ka.
If
any
new
sources
become
operational,
they
would
be
subject
to
NSPS
Subpart
Kb,
the
most
recent
volatile
organic
compound
(
VOC)
standard
applicable
to
storage
vessels.
The
annual
cost
of
this
ICR
is
$
2,181,783.

The
number
of
respondents
was
based
upon
an
examination
of
Aerometric
Information
Retrieval
System
(
AIRS).
The
number
of
storage
vessels
will
not
increase
due
to
the
open
and
closed
time
frame
of
the
regulations.
There
is
the
potential
for
a
3
decrease
in
the
number
of
storage
vessels.
If
an
owner/
operator
substantially
modifies
a
storage
vessel,
it
becomes
subject
the
NSPS
Subpart
Kb.
The
owner/
operator
is
highly
unlikely
to
exceed
the
modification
requirements..

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,
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
this
information
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
EPA
Regional
Office.

For
the
currently
approved
ICR
by
OMB
there
were
no
"
Terms
of
Clearance".

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
4
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,
and
use
such
audit
procedures,
or
methods;
(
D)
sample
such
emissions
(
in
accordance
with
such
procedures
or
methods,
at
such
locations,
at
such
intervals,
during
such
periods,
and
in
such
a
manner
as
the
Administrator
shall
prescribe);

(
E)
keep
records
on
control
equipment
parameters,
production
variables
or
other
indirect
data
when
direct
monitoring
of
emissions
is
impractical;

(
F)
submit
compliance
certifications
in
accordance
with
section
114(
a)(
3)

and,
(
G)
provide
additional
information
as
the
Administrator
may
reasonably
require.

In
the
Administrator's
judgment,
volatile
organic
compounds
(
VOCs)
emissions
5
from
Storage
Vessels
For
Petroleum
Liquids
cause
or
contribute
to
air
pollution
that
may
reasonably
be
anticipated
to
endanger
public
health
or
welfare.
Therefore,
the
NSPS
was
promulgated
for
this
source
category
at
40
CFR
Part
60
Subpart
Ka.

2(
b)
Practical
Utility/
Users
of
the
Data
The
control
of
volatile
organic
emissions
from
NSPS
Subpart
Ka
requires
not
only
the
installation
of
properly
designed
equipment,
but
also
the
operation
and
maintenance
of
that
equipment.
For
the
most
part,
volatile
organic
emissions
are
the
result
of
operation
of
petroleum
storage
vessels
at
petroleum
refineries.
These
standards
rely
on
the
reduction
of
volatile
organic
emissions
by
either
internal
or
external
floating
roofs
or
closed­
vent
systems.

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
floating
roof
or
closed
vent
systems
are
properly
installed
and
operated.
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
note
the
operating
conditions
under
which
compliance
was
achieved.
The
information
generated
by
the
recordkeeping
and
reporting
requirements
described
in
this
ICR
is
used
by
the
Agency
to
ensure
that
facilities
affected
by
the
NSPS
continue
to
operate
the
control
equipment
used
to
achieve
compliance
with
the
NSPS.

Adequate
recordkeeping,
and
reporting
is
necessary
to
ensure
compliance
with
these
standards,
as
required
by
the
Clean
Air
Act.

The
information
collected
from
recordkeeping
and
reporting
requirements
is
also
6
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
Ka.

3(
a)
Nonduplication
If
the
standard
has
not
been
delegated,
the
information
would
have
been
sent
to
the
appropriate
Environmental
Protection
Agency's
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
December
22,
2000
(
65
FR
80854);
no
comments
were
received.

3(
c)
Consultations
No
consultations
were
done..

3(
d)
Effects
of
Less
Frequent
Collection
Less
frequent
information
collection
would
decrease
the
margin
of
assurance
7
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
this
standard
was
collected
on
a
less
frequent
schedule,
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
in
5
CFR
§
1320.6.

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
set
forth

activities
in
connection
with
the
acquisition,

and
distribution
of
the
required
information.

Agency
Activities
Observe

5(
b)
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.

The
Agency
uses
the
performance
test
reports
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
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
11
database
for
the
collection,
maintenance,
and
retrieval
of
compliance
and
annual
emission
inventory
data
for
more
than
100,000
industrial
and
government­
owned
facilities.
The
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
There
are
few
small
businesses
affected
by
this
standard.
The
recordkeeping
and
reporting
requirements
were
selected
within
the
context
of
this
specific
Subpart
and
the
specific
process
equipment
and
pollutant(
s).
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.

The
specific
frequency
for
each
information
collection
activity
within
this
request
is
shown
in

Estimating
the
Burden
and

documents
the
computation
of
individual
burdens
for
the
12
recordkeeping
and
reporting
requirements
applicable
to
the
industry
for
this
Subpart.

The
individual
burdens
are
expressed
under
standardized
headings
believed
to
be
consistent
with
the
concept
of
burden
under
the
Paperwork
Reduction
Act.

is
labor
cost.
There
are
no

are
a
one
