Prologue
This document addresses supposed deficiencies in the following listed tanks or pressure vessels
as recently reported by RCRA_ Further, this document substantiates that all of the listed
tanks or pressure vessels currently meet all engineering requirements necessary to satisfy their
respective construction codes for continued use in their individually designated services.
Before addressing the RCRA findings for the individual items, I wish to establish that the basis
for the RCRA notice of deficiencies are, ultrasonic (UT) thickness examination reports (hereafter
referred to as a "UT report") and a previous assessment. I will also discuss some facts that
someone making an evaluation of a UT report must be aware of and take consideration in any
interpretation made to a UT report.
11171517 111 1 1 , k ,
1. There are no written acceptance standards for UT readings
2- Each UT reading, even though instrument is not moved, may potentially yield a different
thickness due to the numerous amount of variables involved. Some variables include
couplings, transducers, instrument calibration, and surface condition to name a few, not to
mention the "human" factor.
3. A perfectly calibrated instrument in a controlled environment with perfect conditions and all
variables considered may be considered to have an accuracy of approx. +/-0.0010" -but the
industry standard "rule of thumb" accuracy is generally accepted as +/-0.010". Also consider
that acceptable instrument calibration is +/-0M2", i.e., a UT reading of 1/4" plate could yield
any value in a range of 0.252" to 0.24811 and be it would have to considered acceptable. An
tinder -thickness tolerance of 0.0 10", per Code, will be used in this assessment.
4. Other than instrument intricacies noted above there are also manufacturing intricacies to
consider.
-Under-thickness-. The ASME Code has an under -thickness tolerance for plate of, the smaller
of 0-0 10" or 6% of the ordered thickness (ref. UG- 1 6(c), Sect. VIH Div. 1). for example, plate
ordered as 1/4" nominal thick may be as thin as 0.25" - 0.01 " = 0.24" thick.
-Over-thickness: The ASNIE Code has no tolerance for plate over -thickness. And this is
logical. The thicker the plate the higher pressure it may withstand.
For information purposes only -or to provide what I refer to as a "warm & fuzzy feeling"
about common over -thickness expectations, I can advise that 3-10% is common.
5. Thickness Tolerance Summary.,
Based on the above infon-nation, it is reasonable to use the following tolerances for plate
thicknesses- OVER-TMCKNESS (+) = o limit (normally, expect +10111 tol. +-002"/
instr. tol. )
UNDER -THICKNESS (-)= Smaller of; 0.010" or6%

A previous assessment incorrectly concluded "...ultrasonic thickness (UT) examinations
indicatewall thicknesses are below design standards ...... I normally consider a "design
standard" as being a owner/user publication of a requirement above and beyond Code or
legal requirements, which doesn't make sense as used by the, previous assessor. Assuming
the assessor meant "Code requirements", this statement is incorrect. The, assessor is
obviously wrongly comparing the vessels's original service thickness requirements with the
current minimum reported thickness of the unit.

74Based on the information that was provided in the engineering assessment for the Waste
Liquid Fluorocarbon Receiver, the tank was inspected on June 30, 1994 and ultrasonic
integrity tests were performed. The, minimum wall thickness of the tank was found to be
0.256 inches, 0.006 inches over the original thickness of the tank. Based on this increased
thickness measurement, J.D. Prevette, PE, stated in his assessment that the condition of this
tank must be further investigated to ensure its integrity. Provide a discussion of any further
investigations into the structural integrity of this tank that have been conducted since June
1994- Also discuss any corrective actions that have been taken.

1824 (1990) and N.C. State Pressure Vessel Code No. 235007.
Ancill= EQUipmgnt - All ancillary equipment is designed and constructed per DuPont
Engineering Standards which meets or exceeds all Federal Standards.
The vessel was designed on the basis of corrosion coupon tests on materials placed in the tank
for 1-114 years while it was in use, run under the auspices of the DuPont Experimental Station
and Engineering Department, which showed that the corrosion rate for the anhydrous
fluorocarbon mixture was negligible for Hastelloy C-276. Other materials tested, Hastelloy G-3,
Incoloy 825 and Carpenter 20 CB3, were judged to be acceptable but not as corrosion resistant as
Hastelloy C-276. To meet the pressure rating of the tank, only 1/4 inch of Hastelloy C-276 is
required from engineering design calculation.
An elaborate corrosion monitoring and testing program was developed for this system both to
learn more about the corrosiveness of this non -aqueous system and to test out "exotic" alloys
(Monel, Hastelloy, Inconel, Titanium, etc.) for use in similar media and for the future
replacement of this tank. Results of periodic testing, via non destructive techniques are kept on
file at the Nafion 05 area, (see Appendix D-2 Inspection Sheets 1- 42 for the last two (2) tank
testing results and Relief Valve Work Sheets #1 through # 10). ATTACA - J

Erosion is riot a problem in thissystem.
The piping and instrumentation diagram for this tank is given in Appendix D-2. The process
control instrumentation consists of the following,
i - 11'eigh Cell (in lieu of level indicator) with high weight and low weight alarms - readout ani
alarms in continually manned central control is (CCR)
2. Temperature Sensor - thermocouple with remote readout in CCR
3- Pressure Transmitter Controller - Automatic pressure control station in CCR with readout
4. Automatic Conti -of Vent Valve - Operated by pressure control set point automatically or from
S. Vent Gas Flowmeter - Orifice meter in vent line to area process gas scrubber with readout n
'W i
control room.
6, Pressure Sensor for Rupture Disc - alarm in CCR if pressure above five psig as sensed
chamber between rupture disc and relief valve (detects either blown or leaking rupture, dis'*
which could alter the effective burst pressure of the disc).
The weight cell alarm and standard operating procedures prevent overfilling the tank. This is a
closed system. Therefore even in the unlikely me of failure of all safeguards, no spill to the
environment would occur- All of the spill material would be contained in the waste fluorocarbon
spill containment area (See Appendix D-2 W563236), The waste would fill the transfer lines and
thereby upset the rnanufacturing processes discharging the waste and be detected by the normal
process control instrumentation.
In addition to the tank control instrumentation previously outlined, the tank is equipped with a
tualized series mounted rupture disc and relief valve assembly:

The vessel bears the National Board Stamp No. 1924 (1989) and N.C. State Pressure Vessel
D-2b Tank 2 Corrosion and Erosion
The vessel was designed on the basis of corrosion coupon tests on materials placed in the tank
for 1-1/4 years while it was in use, run under the auspices of the DuPont Experimental Station
and Engineering Department, which showed that the corrosion rate for the anhydrous
fluorocarbon mixture was negligible for Hastelloy C-276. Other materials tested, Hastelloy G-3,
Incoloy 925 and Carpenter 20 CB3, were judged to be acceptable but not as corrosion resistant as
Hastelloy C-276, To meet the pressure rating of the tank, only 1/4 inch of Hastelloy C-276 is
required from engineering design calculation.
An elaborate cor-rosiori monitoring and testing program was developed for this system both to
learn more about the corrosiveness of this non -aqueous system and to test out "exotic" alloys
(Monel, Hastelloy, Inconel, Titanium, etc.) for use in similar media and for the, future
replacement of this tank, Results of periodic testing, via non destructive techniques are kept on
file at the Nafion@ area, (see Appendix D-2 Inspection Sheets 1- 42 for the last two (2) tank
testing results and Relief Valve Work Sheets #1 through # 10).
Erosion is not a problem in this system.

1-2c. Tank 2 Management Practices
The process -and instrumentation diagram for this tank is given in Appendix D-2, The process
control instrumentation consists of the following,
1, Weight Cell (in lieu of level indicator) with high weight and low weight alarms
2. Temperature Sensor - Thermocouple with remote readout in CCR and control station
in CCR for controlling water or steam addition to belly heater. High, Low, and High-
Ema
3- Pressure Transmitter Controller - automatic pressure control station in CCR with
readout and set point control. High, Low and High -High pressure alarms in CCR.
4. Automatic Control Vent Valve - Operated by pressure control set point automatically
or from controller manually in CCR.
5. Vent Gas Flowmeter and Flow Integrator - orifice meter - integrator in vent line to
area process gas scrubber with readouts in control room.

7. Automatic Feed Flow Control System - Flow controller for fluorocarbon to reactor.
High -High temperature alarm interlocked to automatically stop addition to the
8. Digestion Timer - Timer for preset digestion time in CCR which cuts off steam flow
to heater at end of time period.
continuous readout in CC.
The weigh cell, alarm and standard operating procedures prevent overfilling the tank. In
addition, all transfers between the Receiver and Reactor are watched and recorded. Therefore, a
weight increase in the, Reactor should match the weight decrease in the Receiver, This is a
closed system and, in the unlikely case of failure of all safeguards, no spill to the environment
is could occur. The vent valve would open and discharge liquid to a knock -out pot (equipped with
a level indicator and alarm) in the manufacturing area process vent system- All of the spill

material would be contained in the waste, fluorocarbon spill containment area (see Drawing
W563236 in Appendix D-2).
In addition to the tank control instrumentation previously outlined, the tank is equipped with a
series mounted ruptun.- disc and relief valve assembly:

As with all the fluorocarbon tanks, emergency vents from the devices are piped away from the
area to an 85-foot fiberglass area stack and there diluted with 24,700 CIFM of heating and
ventilation air. Routine gas flows from the pressure control system are piped to the area vent
header which discharges into a recirculating, caustic scrubbing system which virtually eliminates

be I millyr on the basis of laboratory pilot tests run under the auspices of the DuPont
Experimental Station and Engineering Department. Additional tests which are continuing at this
date show that carbon steel has not been measurably attacked by neutralized aqueous saturated
fluorocarbon waste after four months (<I mil/yr). Thus testing so far indicates the rate is equal
to or less than the corrosion rate in stainless steel and copper for anhydrous untreated
fluorocarbon waste- These tests will be continued indefinitely to confirm the initial finding -
The continuing program is to inspect the tank once/two years and ultrasonically test the wall
thickness (externally) every year unless the ongoing corrosion tests or operating experience
dictates an increased frequency.
Erosion is not a concern or problem in this tank.
The process and instrument diagram for the tank is given in Appendix D-2. The process control
instrumentation consists of the following:
A77A(-H-
(Z/Z I-'-
DEQ-CFW-00031697

2. Temperature Sensor - Thermocouple with remote readout in CCR.
3. Pressure Transmitter Controller - automatic pressure, control station in CCR with readout and
Fill I I I Mmiq I I! I
5. Pressure Sensor for Rupture Disc - alarm in CCR if pressure above five psig as sensed IM
The weigh cell alarm and standard operating procedures prevent overfilling of the wk. Each
transfer from the Reactor is observed and documented to confirm that the loss in Rractor weight
matches the gain and Shipping Tank Weight. This tabulation is maintained on record. The tank
is emptied when full. This is equivalent to a trailer load.
This is a closed system, and no discharge of liquid to the environment would occur in the
unlikely event of a failure of all safeguards. The vent valve would open and discharge liquid to a
closed knockout pot in the manufacturing area process vent system.
In addition to the tank control instrumentation previously outlined, the tank is equipped with a
dualized series mounted rupture disc and relief valve assembly.

As with other fluorocarbon waste tanks, relief valve discharges are piped to the area vent stack
and the normal vent stream is piped to the area recirculating caustic scrubber for removal of
corrosive and toxic components.

of a spill either at the tank or at drumloading, the spill would be totally controlled by thci
containment system. The dike and sump capacity is greater than the maximum volume of the

The 412-gallon 8tainless steel aboveground storage tank
began operations in 1979. The tank collects manufacturing
process waste hydrocarbons for batch filling of 55-gallon
drums. The tank appears to be in good condition. Some rust
is evident on the exterior of the vessel; however, no
bulges, punctures, or indentions are noted, The influent
and effluent piping appears to be soundly welded to the I
vessel. The foundation consists of fo�ir reinforced concretes
ipliers. The piers are in good condition, though the
&rotective coating is peeling in several areas.
Ultrasonic testing is performed on the tank on an annual
basis, and an external inspection of the tank is conducted
every two years. Appendix D-2 of the Fayetteville Works
RCRA Part B Permit Renewal Application contains the last tw;t
tank integrity testing results and the press-ure relief valve
work sheet. The last measured minimum tank wall thickness
is 0.245 inches, while the original shell thickness was
0.250 inches. This is within the corrosion allowance of
0.063 inches. The pressure relief valves. were inspected and
cleaned in December 1994.
The tank is located within a one -foot thick seamless
reinforced concrete diked contaimnent area equipped with a
sump. Thia area has a capacity of 1,200 gallons, and the
concrete is coated with Plasite 9028 Ml and Plasite 4300
(epoxy resins). The containment area contains a I foot deey
sump located in the southwest corner. A visual inspection
of the sump revealed only a few hairline cracks in the
concrete adjacent to the sump. The cracks do not appear to
compromise the integrity of the s=p. The sump collects
material and conveys it to the process sewer and ultimately
the "NAFION" Area common sump.

investigations into the structural integrity of this tank that have been conducted since June
1994- Also discuss any corrective actions that have been taken.

program is to inspect. the tank once/two years and ultrasonically test the wall thickness
(externally) every year unless. -the. ongoing corrosion tests or operating experience dictates
an increased frequency," This statemem-cQniradicis the engineering assessment conducted
on this tank, The assessment included at the t-hd--Qf Section D states that the wall thickness
is below design standards per ultrasonic testing rp-­­s�n May 16, 1995. Mr- J-D,
Prevette, PE, stated that this tank should be thoroughly evalua"d appropriate action
should be taken to repair this tank. Address any further investigations -�the structural

86. Based on the engineering assessment included in this section for the Waste DMSO tank ank
ultrasonic integrity tests conducted on June, 28, 1994 showed the minimum tank wall
thickness was 0.881 inches, whereas the original thickness was 1.075 inches. The
corrosion allowance for this tank is only 0.0625 inches, resulting in the tank being 0.132
inches below the design standard. J.D. Prevette, PE states that DuPont should "thoroughly
evaluate the tanks and take appropriate action." The written assessment provided by
DuPont states "Because the tank has recently been repaired and repainted it is currently
being re -rated to include a new corrosion allowance- DuPont is reevaluating the tank to
verify that existing conditions are satisfactory for the intended purposes of the vessel."
Also, J-D- Prevette, PE, states that the Waste DMSO tank "had been repaired and painted
111 and should bere-rated following an evaluation to determine that existing conditions are
satisfactory for the intended purpose of the vessel." Provide information concerning what
types of repairs were made to the tank both prior to and after this assessment. Discuss the,
re -rating of the tank and specify any new corrosion allowances. This tank should be
reassessed to determine its structural integrity and suitability to handle Waste DMSO.
*NOTE: This tank has been re -rated to 25 psig.

The level readout alarm prevents overfilling the tank. In the unlikely case of a spill either at the
tank or at drumloading, the spill would be totally controlled by the containment system. The
dike and sump capacity is greater than the maximum volume of the tank and twenty 55-gallon
drums. The materhd could be readily pumped back into drums from the sump.
In addition to the tank control instrumentation, the tank is protected by a relief valve,

2. 2 SWM 3 WASTE ITYDROCARBON STORAGE TANK
The 412-gallon stainless steel aboveground storage tank
began operations in 1979. The tank collects manufacturing
process waste hydrocarbons for batch filling of 55-gallon
drums. The tank appears to be in good condition. Some rust
is evident on the exterior of the vessel; however, no
bulges, punctures, or indentions are noted. The influent
and effl�ient piping appears to be soundly welded to the
vessel. The foundation consists of four reinforced concrete
ppiers are in good condition, though the
protective coating is peeling in several areas.
Ultrasonic testing is performed on the tank on an annual
basis, and an external inspection of the tank is conducted
every two years. Appendix D-2 of the Fayetteville Works
RCRA Part B Permit Renewal Application contains the last two
r- M'I tank integrity testing results and the pressure relief valve
work shE��et. The last measured minimum tank wall thickness
is 0.245 inches, while the original shell thickness was
0.250 inches. This is within the corro8ion allowance of
0. 063 inches. The pressure relief valves were inspected and
cleaned in December 1994.
The tank is located within a one -foot thick seamless
reinfoTced concrete diked containment area equipped with a
sump. The area has a capacity of 1,200 gallons, and the
concrete is coated with Plasite 9028 M1 and Plasite 4300
(epoxy resins). The containment area contains a 1 foot deep
sump located in the southwest corner. A visual inspection
of the sump revealed only a few hairline cracks in the
concrete adjacent to the sump. The cracks do not appear to
compromise the integrity of the sump. The sump collects
material and conveys it to the process sewer and ultimately
the "NAFION" Area common sump.

This document assesses the suitability of the subject item in its current structural -state to
maintain safe operation at its existing pressure rating. Assessment is based on data provided and
attached hereto (see "Attachments") using the unifs original construction code, unless the unit is
non -coded in which case the assessment is based on a conservative assumption, as specified.
2.0 Assessement
Assessment �j�mar�- ACCEPTABLE - Contingent Upon Thickness Confirmation
Inspection reports have not been provided to document the unif s current thicknesses,
therefore, assessment is based on safe assumptions which require field documentation
and confirmation of assumptions used.
-2 Tank is a small rectangular tank (TxTxT), of non -coded construction with design based on
"good engineering practices". Pressure envelope design calculations have been performed
C'BPF 222373 / Tank 212-15-23 ". one page, filename 'Y7afliq.wk4 -) and are provided
herewith to establish minimum thickness requirements for maintaining the units specified
original or existing pressure rating of
-MA", ATM psig @ AMEB of
-OPERATING LIQUID LEVEL., Full .0 @approx. I SG
3 The thicknesses requirements for components of the pressure envelope to satisfy the above
specified pressure rating are:
-70-p; 0.01,
-SIDEWAI-1s: 0.1074"
-Borrom.• 0.0" (assuming the entire bottom is uniformly supported)
ZITM=
Ultrasonic (or equivalent) thickness examinations shall be made to the pressure envelope
components specified above and compared to the required thicknesses also specified. The report
shall be attached hereto as a supplement to document actual current thicknesses. Any excess
thickness may be considered as corrosion allowance or simply excess material, above and beyond
design requirements. Any lessor thickness will require further analysis and possible derating of
the unit.

Characteristics, A cearacy, & Special Considerations for UT Thickness Readings.-
, I There are no written acceptance standards for UT readings
.2 Each UT reading, even though instrument is not moved, may potentially yield a
different thickness due to the numerous amount of variables involved- Some
DEQ-CFW-00031790

LI
variables include couplings, transducers, instrument calibration, and surface
condition to name a few, not to mention the possible "human error" factor.
A perfectly calibrated instrument in a controlled environment with perfect
conditions and all variables considered may be considered to have an accuracy of
approx. 4-/400 10" -but the industry standard "rule of thumb" accuracy is
generally accepted as +/-0.010". Also consider that acceptable instrument
calibration is +/-0,002", i.e., a UT reading of 1/4" plate could yield any value in a
range of 0.252" to 0.248" and be it would have to considered acceptable. An
under -thickness tolerance of 0.0 10'*, per Code, will be used in this assessment.
.4 Other than the instrument intricacies noted above there are also manufacturing
intricacies to consider.
Under -thickness:
The ASME Code, Section VIII Div. 1, UG- I 6(c) allows an under -thickness
tolerance for plate of, the- smaller of 0,0 10" -or- 6% of the ordered thickness. For
example, plate ordered as 1/4" nominal thick may be as thin as 0.25 " - 0.0
0.24" thick. This limit is very consmative for non -coded tanks and should not
disqualify a tank without other considerations.
is Over -thickness:
The ASME Code has no tolerance for plate over -thickness, which is logical,
since the thicker the plate the higher pressure it may withstand. For information
purposes only -or- to provide a base point in evaluating reported over -
thicknesses, it is suggested that over -thicknesses of 3% to 10% are common. Any
thickness readings greater than this should not necessarily cause concern but
logical reasoning should be employed to conclude what may cause over -
thickness readings, such as presence of internal product buildup or protective
coatings.
3 Thickness Tolerance Summary:
Based on the above information, it seems reasonable to use the following
tolerances for plate thicknesses-
OVER-TI-HCKNESS ALLOWANCE (+): No limit (normally, expect +109Vmfr, fol.
+ 0. 002 "fOr instrument tolerance)
IJNDER-TT41CKNF-SS ALLOWANCEO: The smaller o
f, 0.0 101' or 6% of the ordered
thickness.
