SUBJECT:
Costs
of
Alternative
Approaches
to
Continuous
Sampling
of
Gas­
Phase
Mercury
Emissions
from
Stationary
Sources
This
memorandum
present
capital,
operating,
and
quality
assurance/
quality
control
costs
for
monitoring
gas­
phase
mercury
emissions
from
stationary
sources
for
two
alternative
approaches
for
continuous
sampling:
continuous
emissions
monitoring
systems
(
CEMS)
and
in­
stack
sorbent
media
(
carbon
tubes).

CEMS
Capital
costs:
$
70,000.
Based
on
a
survey
of
11
manufacturers
of
14
total
and
speciating
CEMS,
Arcadis1
found
an
average
capital
cost
of
$
60,000.
In
addition,
it
is
assumed
that
each
source
would
purchase
a
Hovocal
or
Mercal
unit
to
generate
ionic
mercury
necessary
for
CEMS
calibration.
The
cost
of
either
instrument
is
$
10,000.

Operational
Costs:
$
87,000
The
operational
costs
have
two
components
Routine
maintenance
and
operation
and
QA/
QC
procedures.

Routine
maintenance
and
operation:
Based
on
information
from
CEMS
manufacturers,
Arcadis1
estimated
that
routine
operation
including
periodic
inspections,
monthly
maintenance,
and
data
compilation
and
reporting
would
require
255
technical
hours
per
year
or
$
13,515
(
at
$
53/
technical
labor
hour).
In
addition,
$
2,500
per
year
would
be
needed
for
materials
and
replacement
parts.
Annual
routine
maintenance
and
operation
costs
total
$
16,015.

QA/
QC
procedures:
Two
options
are
available
for
required
calibrations
and
system
integrity:
Option
1:
Weekly
system
integrity
with
ionic
mercury
using
Hovocal
or
similar
technique.
NIST
Standard
solution
cost
is
$
1,000
per
year.
Labor
cost
of
20
technical
hours
per
year,
$
1,060.
Daily
gas
calibration
performed
with
elemental
Hg
requires
the
utilization
of
about
three
gas
cylinders
annually,
and
the
operation
can
be
automated
with
minimal
technician
involvement.
The
estimated
cost
is
$
9,500.
Total
annual
costs
for
this
option
would
be
$
11,560.

Option
2:
Daily
converter
check
with
ionic
mercury
using
Hovocal.
NIST
Standard
solution
cost
is
$
7,000
per
year.
Labor
cost
60
technical
hours
per
year,
$
3,180.
No
daily
gas
calibrations
are
required.
Total
annual
costs
for
this
option
would
be
$
10,180.

RATA:
One
9­
run
RATA
per
year
required.
The
test
would
be
conducted
by
a
testing
contractor
at
a
cost
of
$
37,000.
The
plant
costs
would
be
131
technical
hours
for
procurement,
test
oversight,
and
reporting
or
$
6,943.
The
total
RATA
cost
would
be
$
43,943.
Total
QA/
QC
procedures
annual
costs
are
$
70,138
to
$
71,518
for
an
average
of
$
70,828.

Unit
operating
a
Sorbent
trap:

System:
Each
carbon
trap
will
have
a
three­
section
cartridge:
a
primary
capture
cartridge,
backup
for
breakthough,
and
a
portion
to
be
spiked
for
QA/
QC.
Two
carbon
traps
will
be
run
in
parallel
for
one
week
runs.

Capital
costs:
$
20,000
Capital
costs
for
a
trap
system
have
been
estimated
at
$
8,500.
Capital
costs
including
the
installation
of
the
two
systems
is
assumed
to
be
in
the
order
of
$
20,000.

Operational
Costs:
$
113,000
The
operational
costs
have
three
components:
routine
operational
costs,
laboratory
analysis
costs,
and
QA/
QC
procedures.

Routine
Operational
Costs:
It
is
assumed
that
removal
and
replacement
of
each
trap
will
require
4
hours
per
week
for
a
total
of
8
hours
x
52
weeks
=
416
hours
per
year
or
$
22,048.
In
addition,
it
is
assumed
that
44
technical
hours
will
be
required
to
award
the
carbon
trap
analysis
contract,
and
compile
and
submit
the
quarterly
emissions
report
at
a
cost
of
$
2,332.
Total
operating
costs
are
$
40,916
annually.

Analysis
cost:
The
laboratory
cost
quoted
in
the
Arcadis
report
to
analyze
and
replace
each
primary,
backup,
and
spiked
carbon
trap
including
shipping
an
handling
is
$
220.
For
weekly
sampling
with
two
traps
the
annual
cost
is
$
220x2x52
=
$
22,880.

QA/
QC
procedures:
One
9­
run
RATA
per
year
required.
The
test
would
be
contracted
to
a
test
contractor
at
a
cost
of
$
37,000.
The
plant
costs
would
be
131
technical
hours
for
procurement,
test
oversight,
and
reporting
or
$
6,943.
Routine
QA/
QC
checks
of
1
hours
per
week
per
trap
or
104
hours
or
$
5,512
per
year.
The
total
including
QA/
QC
requirements
RATA
cost
would
be
rounded
to
$
49,000
annually.
