MEMORANDUM
SUBJECT:
Voluntary
Consensus
Standard
Results
for
the
Site
Remediation
NESHAP
Final
Rule
FROM:
Frederick
J.
Thompson,

Acting)
Group
Leader
Source
Measurement

(

TO:
K.
C.
Hustvedt,
Group
Leader
Waste
and
Chemical

Group
(
C439­
03)

At
your
request,
the
Emission
Measurement
Center
(
EMC)
conducted
searches
and
reviews
to
address
the
National
Technology
Transfer
and
Advancement
Act
(
NTTAA)
requirements
on
the
use
of
voluntary
consensus
standards
(
VCS).
The
NTTAA
directs
EPA
to
use
VCS
in
regulatory
and
procurement
activities
unless
doing
so
would
be
inconsistent
with
applicable
law
or
otherwise
impracticable.
This
memorandum
documents
the
results
of
the
EMC
searches
and
reviews
to
determine
if
VCS
are
available
and
practical
for
use
in
lieu
of
stationary
source
methods
cited
in
the
Site
Remediation
NESHAP
Final
Rule.

In
1998,
the
EMC
began
implementing
the
requirements
of
the
NTTAA
by
conducting
searches
to
identify
VCS.
Searches
continue
to
be
performed
to
meet
the
requirements
of
the
NTTAA.
While
we
have
made
a
reasonable
effort
to
identify
and
evaluate
potentially
practical
VCS,
our
findings
do
not
necessarily
represent
all
potential
alternative
standards
which
may
exist.

The
EMC
participates
in
the
American
Society
for
Testing
and
Materials
(
ASTM),
which
is
one
of
the
most
active
VCS
organizations
on
emissions
testing,
and
has
been
invited
to
participate
in
the
USA
Technical
Advisory
Group
for
International
Organization
for
Standardization
(
ISO)
relating
to
emissions
monitoring.
We
expect
these
additional
efforts
will
help
us
to
support
a
periodic
review
of
all
EPA
reference
methods
and
performance
standards
for
possible
incorporation
by
reference
(
IBR)
of
VCS
in
lieu
of
or
as
alternatives
to
EPA
procedures.
We
anticipate
that
these
activities
will
provide
an
opportunity
for
further
review,
consideration
and
possible
IBR
of
VCS
overlooked
in
the
National
Standards
Service
Network
(
NSSN)
searches
or
finalized
after
work
group
closure
in
the
EPA
rulemaking
process.

We
conducted
searches
for
the
Site
Remediation
NESHAP
Final
Rule
through
the
Enhanced
NSSN
Database
managed
by
the
American
National
Standards
Institute
(
ANSI).
We
also
contacted
VCS
organizations,
and
accessed
and
searched
their
databases.
Searches

in

No

and
SW
846
Method
9095A.
Please
see
the
attached
tables
for
a
detailed
summary
of
our
findings.

The
attached
tables
describe
the
VCS
found,
which
EPA
standard
reference
method(
s)
the
VCS
potentially
affects,
if
the
VCS
is
equivalent
to
the
EPA
standard
reference
method,
and
EPA's
comments
after
review
of
the
standard.
During
the
search,
if
the
title
or
abstract
(
if
provided)
of
the
VCS
described
technical
sampling
and
analytical
procedures
that
are
similar
to
EPA's
reference
method,
the
EMC
ordered
a
copy
of
the
standard
and
reviewed
it
as
a
potential
equivalent
method.
All
potential
standards
were
reviewed
to
determine
the
practicality
of
the
VCS
for
this
rule.
This
review
requires
significant
method
validation
data
which
meets
the
requirements
of
EPA
Method
301
for
accepting
alternative
methods
or
scientific,
engineering
and
policy
equivalence
to
procedures
in
EPA
reference
methods.
The
EMC
may
reconsider
determinations
of
impracticality
when
additional
information
is
available
for
particular
VCS.

The
search
identified
ten
VCS
that
were
potentially
applicable
for
this
rule
in
lieu
of
EPA
reference
methods.
After
reviewing
the
available
standards,
EPA
determined
that
eight
of
the
ten
candidate
VCS
(

identified
for
measuring
emissions
of
the
HAP
or
surrogates
subject
to
emission
standards
in
the
rule
would
not
be
practical
due
to
lack
of
equivalency,
documentation,
validation
data
and
other
important
technical
and
policy
considerations.
These
eight
methods
are
listed
in
Attachment
1,
along
with
the
EPA
review
comments.
Two
of
the
ten
candidate
VCS
(
ASME/
BSR

ASME/

are
new
standards
under
development.
These
two
methods
are
listed
in
Attachment
2,
along
with
the
EPA
review
comments.

I
hope
our
research
into
this
matter
has
been
useful
and
timely
to
your
Group's
efforts
in
this
rulemaking.
