The
TCEQ
entered
into
eight
Agreed
Orders
with
six
companies
at
seven
sites
to
make
sure
activities
and
emission
reductions
could
become
federally
enforceable.
This
proposed
SIP
revision
is
site
specific.
There
are
a
variety
of
projects
contained
with
in
the
Agreed
Orders,
some
will
result
in
quantifiable
emission
reductions
and
others
will
improve
the
operations,
maintenance,
and
reliability
of
systems.
TCEQ
calculated
the
emission
reductions
in
terms
of
allowable
emissions.
As
delineated
in
the
Agreed
Orders
with
each
company
the
reductions
stipulated
in
each
order
will
not
be
used
for
future
offsets
or
banking.
Due
to
this
stipulation,
some
of
the
companies
have
reserved
some
of
the
reductions
gained
by
the
submitted
projects
for
their
own
future
offsets
and
banking.

do
not
take
credit
for
these
emission
reductions
whether
they
are
delineated
in
the
Orders
as
required
reductions
or
are
reserved
by
the
companies
for
future
use.

ExxonMobil
installed
a
wet
gas
scrubber
on
the
fluid
catalytic
cracking
unit
in
order
to
reduce
sulfur
dioxide
(
SO
2)
emissions.
The
previous
permit
allowable
for
Emission
Point
Number
(
EPN)
06STK_
001
was
12,833.75
tons
per
year
(
TPY),
established
in
TCEQ
Permit
#
19566.
This
allowable
was
established
for
the
grandfathered
FCCU
CO
(
carbon
monoxide)
boiler
stack
in
order
to
assure
that
any
expansion
projects
elsewhere
in
the
plant
would
not
cause
emission
increases
from
the
unit.
This
project
was
originally
submitted
as
a
voluntary
emissions
reduction
permit
(
VERP).
The
new
allowable
rate
for
EPN
06ST_
003,
the
FCCU
Scrubber
Stack,
is
2,849.19
TPY
SO
2.
The
new
allowable
is
reported
to
be
based
upon
an
outlet
concentration
of
200
ppmv.
The
emission
reductions
from
this
project
is
9,984.6
TPY
SO
2
(
12,833.75
TPY
­
2,849.19
TPY).
These
reductions
are
enforceable
through
TCEQ
Permit
#:
46534.
The
Company
reserved
300
TPY
SO
2
to
be
allocated
to
other
projects,
and
any
SO2
emissions
reductions
above
9400.
This
left
no
more
than
9,400
TPY
and
no
less
than
584
TPY
in
SO
2
reductions.

By
December
31,
2004
ExxonMobil
implemented
improved
practices
and
maintenance
procedure
for
the
two
ketone
units.
These
improved
practices
and
procedures
will
help
to
reduce
the
fugitive
emissions.
The
emissions
are
reported
under
EPN
41FUG_
001,
EPN
41FUG_
002,
EPN
42FUG_
001,
and
EPN

The
company
will
prepare
a
written
plan
describing
the
detailed
maintenance
procedures.
The
company
will
keep
a
copy
of
the
plan
available
for
review
on
site
for
2
inspection
by
TCEQ.
These
improved
practices
were
submitted
as
part
of
VERP
#:
47358,
which
is
currently
under
review
by
TCEQ.
The
leak
detection
and
repair
program
for
fugitive
emissions
have
also
been
changed.
The
program
has
been
changed
from
28
RCT
to
the
more
stringent
28
VHP.
Leaks
from
pumps
and
compressors
are
repaired
at
a
lower
leak
detection
limit,
2,000
ppmv
verses
10,000
ppmv.
This
project
is
estimated
to
provide
a
volatile
organic
compounds
(
VOC)
reduction
of
4
TPY.
The
Company
did
not
reserve
any
of
the
VOC
emission
reductions
that
would
be
achieved
by
these
practices.

ExxonMobil
is
building
a
new

This

The

The
VOC

as
reported
in
the
Emissions

for
2001­
2003
averaged
approximately
37
TPY.
The
company
assigned
29

of
the

The
Company
did
not

Since
the

The
Company
has
reported
the
fugitive

The
estimated

During

According

The

The
Company
did
not
reserve
for
future
use
any
of
the
emissions
reductions
that
would
be
achieved
by
this
installation.
The
TCEQ's
technology
control
requirements
for
operation
of
the
degassing
system
would
require
3.1
TPY
of
H2S
reductions.
The
Company
agreed
in
the
permit
to
more
effective
controls
and
thereby
achieve
an
additional
1.6
TPY
of
H2S
emissions
reductions.

Premcor
has
installed
and
configured
for
use
the
Ops
EnvironmentalTM
Software.
This
system
will
integrate
a
multi­
media
environmental
data
management
system
linked
to
60
existing
boiler
and
process
heater
continuous
emissions
monitoring
systems
(
CEMS)
and
the
Refinery
process
information
system.
The
software
is
designed
to
improve
tracking
of
actual
emissions,
operator
response
times
and
corrective
action
by
the
Company.
There
are
no
quantifiable
emission
reductions
from
the
implementation
of
this
measure.

The
Company
has
made
equipment
modifications
to
improve
the
regenerative
thermal
oxidizer
(
RTO)
for
wastewater
treatment
unit
#
8742.
The
following
modifications
are
designed
to
improve
the
reliability
of
the
unit
and
help
prevent
RTO
shutdowns.
Since
the
nature
of
these
modifications
are
to
prevent
emission
events
associated
with
RTO
shutdowns
and
not
a
reduction
in
allowable
emissions,
there
are
no
quantifiable
emission
reductions
from
the
implementation
of
these
measures.
7
The
modifications
are
listed
below.
°
Redundant
flame
detectors
with
100%
voting
logic
to
minimize
false
signals
that
can
cause
unwarranted
shutdowns
and
instrument
air
purge
to
flame
scanner
path.
The
improved
flame
detector
design
will
also
allow
on­
stream
cleaning.
°
Fiber
optics
control
communications
wiring
that
will
be
less
susceptible
to
lightning
induced
voltage
spikes.
°
New
motor
actuated
combustion
air
and
fuel
flow
control
valves
that
do
not
use
mechanical
linkages
which
for
combustion
control.
°
Modified
deal
drum
level
control
design.
°
Deletion
of
damper
fauld
shutdown
(
kept
alarm
alive).
°
Reduction
of
induced
draft
fan
vibration
and
bearing
temperature
shutdowns
(
kept
alarm
active).
°
Replacement
of
all
damper
actuators.
°
Replacement
of
both
hydraulic
pumps.
°
Adjustment
of
burner
minimum
fire
to
lowest
possible
setting.

Premcor
will
also
improve
the
RTO
by
upgrading
the
master
electronic
control
system
by
June
30,
2005.
As
with
the
previously
listed
modifications
to
the
RTO,
there
are
no
quantifiable
emission
reductions.
The
Company
will
be
making
the
following
modifications
to
the
Master
electronic
control
system
to
the
RTO.
°
Replace
the
new
master
Programmable
Logic
Controller.
°
The
logic
programming
will
be
reviewed
and
revised
to
simplify
its
function
while
maintaining
necessary
fail
sage
operational
integrity.
°
Certain
RTO
control
loops
sill
ve
moved
to
the
existing
distributed
Control
System
to
allow
for
better
control
and
tuning.

By

Premcor
will
complete
the
installation
of
a
wet
gas
scrubber
at
the
outlet
of
the
regenerator
on
the
fluid
catalytic
cracking
unit
#
1241.
The
wet

scrubber
uses
caustic
and
water
solution
sprays
to
remove
sulfur
and
particulates
from
the
generator
flue
gas.
BACT
requirements
for
flexible

reduction
of
3,300
TPY

will
reduce

by
4,400

The

are
considered
to
be
voluntary.

found
in

Recommendation
EPA
has

the
submitted
Agreed
Orders.
The
emission
reductions
memorialized
in
the
Agreed
Orders
between
each
of
the
companies
and
TCEQ
represent
actions
that
appear
to
be
taken
above
and
beyond
the
requirements
of
any
State
or
Federal
Agency.
The
emission
reductions
and
other
measures
outlined
in
each
of
the
Orders
are
permanent
and
can
not
be
used
for
future
banking,
trading
or
offsets.
Only
emission
reductions
specifically
identified
in
the

as
being
reserved
for

use
may
be
used

will
aid
in
the
improvement
of
