A cathodic Protection Survey was performed on Oct 15, 2005 ctt the Wholesale Fuels Facility located at 2200 E.
Brundage Ln. Bakersfield, CA.
The system layout is as follows: the rectifier is mounted on the rtirth wall of the store stockroom. The anode bed is
located at an undetermined location on the west side of the store property. The tank structure leads come into the
rectifier from a northerly direction; the tanks and pump units are Iccated just North of the warehouse building. In order
to obtain valid cathodic protection data the reference electrode (11a1f cell) was placed in the dirt area located on the
Eastside of the warehouse near the chain link fence.
The cathodic protection tests were performed with an interrupter placed in the DC circuit at intervals of 6 seconds on
and 3 seconds off. The results are tabulated in the succeeding pa+~es. The tank meets the requirements for cathodic
Protection under the Code of Federal Regulations, 40 CFR Part ~$0. The cathodic protection levels of protection were
taken with regards to the following NACE Standards:
• RP0169-92 Standard recommended practice: Control of Corrosion on Underground or Submerged Metallic
Piping Systems.
• RP 0285-85 Standard recommended practice: Control ryf External Corrosion on Metallic Buried, Partially
Buried, or Submerged Liquid Storage Systems.
• STI R892-91 Recommended practice for Corrosion Protection of Underground Piping Networks Associated
with Liquid Storage and Dispensing Systems.
• American Petroleum Institute (API) Recommended Practice 1632, Cathodic Protection of Underground
Petroleum Storage Tanks and Piping Systems.
While the Environmental Protection Agency (EPA) and local regulations mandate testing to be conducted on three-
year intervals to determine the effectiveness of the installed systems, experience and good engineering practice
dictate that an assessment on this type of system be made on ar, annual basis. This, coupled with the required bi-
monthly inspections by the Wholesale Fuel Facility personnel, WIII assure the continued effective operation of the
installed corrosion control systems.
The annual inspection of the cathodic protection systems should consist of structure-to-soil potential measurements,
current output of the anode bed, and a summary report to includa field data and recommendations as required.

OPERATING AND MAINTENANCE MANUAL
GALVANIC ANODE AND IMPRESSED CURRENT
CATHODIC PROTECTIOP~ SYSTEMS
The cathodic protection system for the six underground service tanks consists of an impressed
current system. Maintenance of the impressed current system consists mostly of rectifier
monitoring, troubleshooting, and repair. The information Contained in this manual concerns itself
with impressed current systems.
Proper maintenance is essential for the operation of the cathodic protection system. The complete
or partial failure of a cathodic protection system is not usually accompanied by any visible signs.
Very often the only means of detection is noting the change in structure-to-soil potential through
the -use of electrical instruments. If there is a failure on a cathodic protection system, the
relatively slow process of corrosion resumes, resulting in eventual large repair/replacement
expense to the owner. Therefore, it is important to properly maintain all cathodic protection
systems.
In addition to the change in structure-to-soil potentials as mentioned above, several other
indications of failure may be detected. Changes in rectifier output in impressed current type
systems may indicate problems. If the system is totally inoperative, a drop in power consumption
will be indicated on the monthly power bill.
Maintenance and operation of cathodic protection systems does not require a thorough
knowledge of corrosion theory; however, knowledge of fhe basic principles of corrosion will be
useful in understanding how cathodic protection works. ~JVith this understanding, measurements
made during field surveys will become meaningful and th+e measurement techniques can be more

readily adapted to unusual situations.
An introduction to corrosion and cathodic protection theory, and the significance of structure
potentials is provided in Section 3.0 of this manual.
1.0 Monitoring and Maintenance Procedures
For the purpose of this Operating and Maintenance 1~vlanual, monitoring refers to routine
inspection on a monthly basis by Wholesale Fuels persoiii~el. Maintenance is the more detailed
testing and adjustment of the system which should be perl`ermed by qualified Corrosion Control
Personnel.
1.1 Monitoring
The following procedure should be followed during rifonthly monitoring of your impressed
current cathodic protection systems:
• Read the rectifier voltage and current output (see rectifier data sheet, section 4.3).
Rectifier output and structure potential readings shall be considered acceptable
when they are within +/- 20% as compared to the respective values recorded at the
time of the last annual survey.
The data for the System is listed in the post installation Survey report field- data (Sec. 4.3 of this
manual). Because normal system adjustments may be made during annual maintenance surveys,
the most recent survey data should be referenced when evaluating the monthly maintenance
readings.
If the readings are acceptable, then no further field work is required. If the readings are not
acceptable, then the trouble shooting procedure outlined it1 Section 2.0 should be followed.
1.2 Maintenance
d
teve Underwood Wholesale FuelsryO 8~ M.docv~ ~ ~ ~~ Page~5
'The following procedures should be followed during the annual cathodic protection resurveys of
both types of cathodic protection systems:
1. Examine each rectifier for physical damage from: vandalism, wind; clogged
ventilation, lightning, exposure or overheating.
2. Read and record DC voltage, DC amperage and tap setting on rectifier
maintenance sheets. If there are significant changes in output when compared with
records of previous visits, further investigation is warranted.
3. Turn the rectifier off. Feel the diodes for uneven heating. If all the diodes are not
at the same temperature, employ the tratil~le shooting procedures described in
Section 2.0
4. While rectifier is still off, check the bolted electrical connections for heat and
looseness.
5. Calculate rectifier efficiency:
Percent Efficiency = DC Power/AC Powtr x 100
DC Power = DC Volts x 17~C Amperes
AC Power = AC Volts x AC Amperes
Once the rectifier unit has been inspected and ready then proceed with the potential survey
for both systems. Record structure-to-soil potentials at the following locations:
1. At all test stations.
2. At vent and product piping to monitor ele~tt`cal isolation status.
Anode current should be measured at each wire shunt in each system type. Anode shunts
are typically located at an anode junction box at the rectifier and at, the anode test station
on the galvanic anode system. All data should lie recorded on a cathodic protection
survey data sheet. If the test data does not conform to the established criteria for cathodic
protection, institute the trouble shooting procedures: Typical survey data sheets are found
in Section 4.4 of this manual.

2.0 Trouble Shooting
When impressed current systems are operating improperly, several considerations should be
explored prior to testing rectifier components and circuits~~
1. Past Data - DC output of rectifier
Structure-to-soil potentials
Electrical isolation Checks
2. New Construction - Cable breaks
Inadvertent electrical shorts to foreign structures
3. Installation of new foreign cathodic protectitrn systems.
4. Extensive use of DC in area.
5. Recent storms.
2.1 Svstem OneraHon
Many rectifier problems are obvious to the experienced technician and do not require elaborate
inspection procedures. The obvious should never be ignored. The majority of rectifier failures
occur from: blown fuses, loose connections, defective meters or open DC cables. These can
generally be detected by a simple visual inspection of the tYrlit.
1. No DC voltage and/or current.
A. Blown DC fuse: If this fuse fails, a DC vriltage will be observed on the rectifier
meter but no current.
(1) If apparently due to steady overload; reduce the output slightly.
(2) If the fuse blows repeatedly, even ~.vith the output reduced, a short circuit
may exist, caused by a defective rectifier component or underground short.
Determine whether the short is infernal or external to the rectifier. With
the rectifier off, disconnect the ane of the DC output cables from the
rectifier and re-energize the rectifier: If the fuse still blows, the short is

~-
internal to the rectifier. In that case, isolate the component by the
procedure outlined in the following section.
(3) If the fuse blows occasionally for rio apparent reason, the cause maybe:
(a) Temporary overload due to seasonal changes in anode bed
resistance.
(b) Surges of AC voltage.
(c) Intermittent shorts in rectifier' components.
(d) Intermittent shorts in ground bed circuit.
B. Blown AC fuse: if this fuse fails, neither +/oltage nor current will be observed in
the DC circuit. Check the fuse with a light or AC voltmeter. Replace if necessary.
Do not overlook the possibility that service to the rectifier maybe interrupted.
C. Loose connections: check all connections, fine and coarse transformer tap
adjustments and diode connections.
D. Defective meters:
(1) DC voltmeter -.if a current output is indicated on the DC ammeter, but no
voltage is observed, place a portable voltmeter across the DC terminals. If
no voltage is indicated on the portable meter, check to be sure the ammeter
is not frozen by turning the unit off If a voltage is recorded, check for an
open in the voltmeter circuit. This can usually be done by removing the
voltmeter and visually inspecting the circuit. If no defect is observed,
replace the voltmeter.
(2) DC ammeter - if a voltage is indicated on the DC voltmeter, but no current
is observed, insert an ammeter in the DC circuit. Turn the unit off and
disconnect the positive DC cable: connect the positive terminal of the
ammeter to the rectifier lug and the negative terminal to the anode cable.
Turn the unit on and observe the meter. If current flow is indicated, check
the ammeter circuit for loose or ripen connections. If no defects are
Steve Underwood -Wholesale Fuels O & M doc~~ ~~~~~~~~~~~ ~ ~~~~~~- ~ Page 8
observed, replace the ammeter.
E. Opens in ground bed cables: one of the metre common problems which develop
with impressed current systems is a break in the anode circuit. Detection of an
open in either the positive or negative leg is relatively simple. Monthly data on
rectifier current and voltage outputs is used to determine if the bed has slowly
deteriorated or if the cables have been severed. In most cases where a faulty DC
lead is encountered, the voltage output will 1~e near the level last recorded, but the
current output will be slight, if any. The steps taken to determine which lead is
open and the method to locate the break arc as follows:
(1) Open in negative cable - if the break is suspected in the negative
connection, attach a test lead fram the structure to the negative DC
terminal of the rectifier. If the negative cable is in fact open, the test lead
will complete the circuit and current flow will be observed. Examine the
route of the negative cable to determine if any digging has recently
occurred in the area. If the location of the break is not obvious, use a cable
locator to locate the open. Do nt~C discount a broken connection to the
structure.
(2) Open in positive cable - a break in the ground bed circuit most commonly
occurs in the positive leg. This is due to the fact that any break in the
insulation which exposes bare copier will result in current discharge to
ground at that point. A complete severance of the cable will shortly
follow. If the .open occurs before the first anode, the entire ground bed
will be lost. It should be noted, lirtwever, that breaks may occur at any
point within the circuit. If only a portion of the anode string is
disconnected, the anode bed resistance will increase appreciably. _ To
determine if the positive leg is in fact open, install a temporary anode bed
and connect to the positive terminal of the rectifier. If current flows in the
Steve Underwood -Wholesale Fuels~O & M.doc ~ ~~~~~~~~~ ~ ~ ~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~ Page 9
temporary circuit, disconnect and use a cable locator to pinpoint the break.
Disconnected anodes within a vertical column cannot normally be
serviced. Therefore, identifying the exact location of such a failure is
meaningless. It maybe feasible to maintain effective corrosion mitigation
despite one or more lost anodes b~ increasing rectifier output voltage.
However, several factors must be considered, and parameters of ground
bed operation are beyond the scope of this manual. A qualified consultant
should be retained before modifications are implemented.
2. If the DC voltage is only about half what it should be (use circuit resistance as calculated
from previous rectifier readings) when the current output is at the maximum, the trouble
maybe:
A. Open circuits in one or more of the diodes resulting in half-wave rather than full-
wave rectification. This can be determined by using the diode troubleshooting
techniques described in the next section.
B. Rectifier connected for 240 VAC while 120'VAC is being supplied.
2.2 Rectifier Diagnostics
When the rectifier unit is not functioning properly, systerriatically isolate the components. until
the defective part is located. The procedure to follow is:
1. Check the line voltage by placing the leads from an AC voltmeter or circuit tester
across the line side of the circuit breaker.
2. Check across the load side of the circuit breaker. The voltage should be the same
as at the line side.
3. Check the rectifier input tap for loose connections and to verify adjustment for the
proper AC voltage.
4. Check the secondary transformer windings with an AC voltmeter or circuit tester.
If AC voltage is applied to primary windings, but none is present at the secondary,
Steve Underwood Wholesale Fuels O & M doc ~~~-~~~~~-~ ~ ~ ~~-~ ~~~~~~~~ Page 10 ~
listen for an audible hum from the transformer.
A. If no tone is detected, measure the resistance of the primary winding with
an ohm-meter (be sure to turn the unit off). The resistance should be
within the range from one to ten ohms.
B. If a tone is detected, the resistance of the secondary winding should be
measured. If either resistance was quite high, the winding is essentially an
open circuit and the transformer most be replaced. Make sure that the high
resistance is in the winding and not al connection lug.
The entire secondary winding mad be measured between highest coarse
tap and the highest fine tap. If the circuit breaker trips, indicating a short
circuit, the transformer may be isolated from the DC circuit by removing
the secondary tap adjustment terminals. If the circuit breaker continues to
trip, inspect for visible shorts between the transformer leads. If it holds,
the short is not in the transformer but in the DC circuit.
5. Check the AC voltage supplied to the rectifier diodes. This voltage should be the
same as measured at the secondary transformer winding. If AC is present at the
secondary winding, but not at the diode terminals, check the leads from the
transformer to the diodes. Replace any defective lead.
6. If AC is applied to the diodes, use an ohm-meter to determine the diode
resistance.
Disconnect each diode and measure both forward and reverse. resistance with an
ohm-meter. The forward resistance should Ire negligible and the reverse resistance
infinite. If either measurement does not concur, replace the diode.
If the AC circuit breaker trips, isolate the diode from the DC circuit. If the breaker
continues to trip, the diode is defective and trust be replaced.
7. If the circuit breaker does not trip when the diode is removed but does when the
diode is connected, there is probably a short in the external DC circuit. This may
10
Steve Underwood ~-Wholesale Fuels O & M doc ~ ~~~~~ ~~ ~~ ~~ ~ ~ Page 11~
be verified by removing the anode and structure leads, one at a time.
8. If DC is present at the diode, but not at t1~e rectifier output terminals, check for
loose connections or open leads between these points. This may be done by
measuring the DC voltage between the c~Yc~de output negative and each point in
question on the positive circuit leg. The procedure is reversed to troubleshoot
connections in the negative circuit leg.
9. If DC voltage is present at the rectifier output terminals, but no current is flowing,
there is an open in one of the external DC leads.
10. Faulty meters may cause the rectifier tv appear defective when it is actually
functioning properly. The meters may be +c~tecked with portable meters known to
be accurate.
11. A faulty lightning arrestor in this rectifier (AC or DC) may be isolated by
removing it from the circuit. The rectifier +uvill operate with either or both lighting
arrestors removed.
END OF TROUBLE SHOOTIl'~1G SECTION
2.3 Safetv Procedures
Because cathodic protection systems operate at voltages well below the shock hazard level as
defined by OSHA 2207 Subpart K 1926.405(K), no special precautions during monitoring or
maintenance procedures are required.
If the unit has been installed correctly with regard for AC power grounding, then no significant
risk of shock hazard resulting from unit damage or malfuiYCtion will be present.

The AC adjustment taps should be considered hazazdetts. Power should be shut off to the
rectifier before adjusting or servicing. As with any electrical device, servicing should not be
attempted by unqualified personnel.
3.0 How Cathodic Protection Works
3.1 Basic Principles of Corrosion
When a metal corrodes, electrical current is generated. The area where corrosion occurs is called
the anode. The current enters the soil or other conductive environment at the anode and flows to
the non-corroding area, or cathode. At the same time, an +etlual quantity of electron current flows
from the anode to the cathode through the metal. At the cathode the positive and negative
current neutralize each other. For corrosion to occur, all ~t~ur parts of this circuit must be_ present:
a current generator or anode; a conductive environment such as soil or water; an electron path
which must be a metal; and a cathode.
There are many reasons why a certain area on a structure may become an anode or a cathode. If
two different metals aze present one will become an anode and the other a cathode; this is called
galvanic corrosion. Anodes and cathodes can form on a single metal if there is even a slight
variation in the environment between different areas on the metal. These can be differences in
the amount of air which can reach the metal surface, such as can occur in loosely and tightly
packed soil, differences in soil or water properties such ai dissolved salts or acids, or differences
in the moisture content of the soil. Small differences in tttetal condition between different areas
on the metal can also cause anodes and cathodes to form: These can be differences in surface
condition such as abraded and non-abraded, clean and rusty, new and old, or differences in
manufacturing conditions such as hot-rolled and cold-rolled or stressed (bent) and unstressed.
Even threading of a pipe can cause the threaded areas to become anodic to the unthreaded area of
the pipe.

Steve Underwood Wholesale Fuels O ~ M.doc .~ ~~~ ~~~ ~ ~ ~ ,~ Page 13
While these forms of attack have different causes, they all involve the same four parts of the
corrosion circuit; an anode, a positive path, a negative patiiy and a cathode.
3.2 Cathodic Protection Principles
Cathodic protection uses the principle of corrosion. The four components of the corrosion circuit
are present except that instead of having an anode on the metal we want to protect we connect a
more active anode to the metal to supply excess negative current. This makes the entire surface
of the metal we want to protect act like a cathode. Corrosion principles say that corrosion does
not occur at a cathode and we can therefore protect a metal by electrically connecting to it a
current source or anode. Cathodic protection is really a farm of corrosion but by understanding
the corrosion circuit we can make corrosion an ally.
The cathodic protection systems installed on the 6 underground service tanks is of the "impressed
current" type, in which the current is not supplied by the anodes, but is supplied by an external
direct current source, in this case, rectifiers. The anodes are, however, consumed at a slow rate.
As far as the protected metal is concerned, the impressed current system is the same as a
sacrificial anode system. However, the current is not beittg generated by corrosion of the anode,
and an inactive material such as cast iron can be used An anode is still required so that the
current can enter the environment.
3.3 What Can Cathodic Protection Do and Not Do's
A cathodic protection system can, in actual practice, protect a buried or submerged structure
indefinitely, provided that he cathodic protection systettl is properly designed, operated, and
maintained. Maintenance of cathodic protection systems does not require access to the entire
structure, so cathodic protection systems on buried storage Tanks can be practically maintained.
Cathodic protection is also the only practical method of protecting large buried or submerged
structures which were not originally protected or on which the original paint or coating protection
has failed.
13
~~Steve Underwood -Wholesale Fuels O & M doc ~ ~~~~~~~~~~~~ ~ ~~~~~~~~ ~~~~~~~~~~~~~~ ~ ~~~~~~ Page 14 ~
Cathodic protection does have certain limitations. First, the structure must be surrounded by an
environment which can conduct the electrical current from the anodes to the structure. In soil the
conductivity is primarily due to the presence of moisture, As the amount of moisture and the
amount of dissolved salts increase, the soil becomes more conductive. Soil in a salt marsh is an
excellent conductor, whereas moist soil such as loam is a good conductor, and dry sand is a poor
conductor.
Air cannot conduct electrical currents. Therefore, structures cannot be protected above ground or
out of water using cathodic protection.
It is not simply coincidence that highly conductive environments are also usually highly
corrosive. This is because the corrosion cell can act more readily over a longer distance when the
conductivity of the environment is high, allowing more current to flow.
Another thing that cathodic protection cannot do is to improve the condition of any already
corroded structure. Cathodic protection can stop further corrosion, but it cannot "plate back"
corroded metal.
3.4 How Do You Tell If A Cathodic Protection Svs~etn Is Working?
Because a cathodic protection system is electrical in nature; it is possible to determine whether or
not a cathodic protection system is working by taking electrical measurements. Because the soil
in which the .structure is buried or the water in which it is submerged is conductive, these
measurements are usually performed using the environment as a conductor.
The single most important measurement made in cathodic protection field surveys is the potential
of the structure. If it is more negative than the environment, it attracts positive charges that
cannot leave. If positive charges cannot leave, then corrost~n cannot occur.
14
Steve Underwood Wholesale Fuels O & M doe ~~~ ~ ~ ~ ~ Page 15 ~
Measurements of single potentials cannot be made; ail that can be measured are potential
differences. The potential difference between the envirorment and the structure can be measured
using a suitable meter.
If a metallic probe is used to make contact with the envircrntnent, the potential of the probe would
be unknown, so a measurement of the potential difference Between the probe and structure would
depend on two variables and would not be meaningful. Itt t~rder to provide a means of contacting
the environment, reference electrodes have been devela~ed that have stable and reproducible
potentials. By measuring the potential difference between a standard reference electrode and a
structure, a value is obtained for the potential of the struciltre which is dependent only on the type
of reference electrode and the structure's potential.
A portable copper-copper sulfate reference electrode ina~y be used for all routine potential
monitoring. The test stations each contain PVC tubes vtvhich extend down closer to the tank
surfaces, to measure a more local potential at the tank.
Measuring Device: The meter used to measure the potential difference between the reference
electrode and the structure is similar to an ordinary volt teeter. However, an ordinary voltmeter
cannot be used to measure these potentials because it has tdo low of an internal impedance. Low
impedance allows enough current to flow in the, measuritg circuit to affect the measurement.
This is primarily because the reference electrode will change potential when appreciable current
flows through it. A current of 1 mA in the measuring circuit will affect the potential of the
reference electrode to the point that the readings obtained are unreliable. By correctly using a
meter specifically designed (10 meg ohms per volt or greater internal impedance) for use in
making these potential measurements, the current flowing in the measuring circuit will be kept
well below 1 mA.
15
Steve Underwood- Wholesale Fuels O & M doe _~:~,~~,,~.~a~_ ~ ~~ s.ub~.~~.~ ~~ _ ~ ~~ Page 16
Electrical Connections With Structures: In making field measurements of structure potentials, the
only requirement is a good electrical connection with the structure. The potential being measured
depends primarily on the location of the reference electrode (hence the PVC tube described
earlier), not on the place where the connection is made to tiie structure. Each test station contains
dual test leads to its corresponding tank, for the purpose of establishing the electrical connection.
The rectifier negative terminal should not be used for this purpose with the cathodic protection
system on due to measurement error introduced by the resistance of the lead cable.
When the portable reference electrode is placed close to t$e structure, the potential measured is
that of a local area of the structure near the reference electrode. When the reference electrode is
placed far from the structure, the potential measured is close to an "average" potential of the
structure. Since there will probably be a difference bet~iVeen the local and average potential
readings, it is important that when the potentials are to be compared with potentials taken earlier
or later, the portable reference electrode be placed at apprtt~imately the same location each time a
potential is measured.
Potential Measurements: It is usually desirable to malre potential measurements with the
protective current turned "on" and "off'. Whenever the potential is read with the protective
current off, this fact should be recorded.
When making potential measurements there are several indications that the readings obtained are
not accurate; e.g. if the meter always reads exactly the satrie value with the reference electrode in
different locations, or if the meter reading slowly fltictl~ates over a range in excess of 10
millivolts. Normal meter behavior is to slowly approach a stable reading. Stable readings should
be reached within 10 seconds.
1b
Steve Underwood Wholesale Fuels O 8~ M doc w ~ ~M ~ 'Page 17
Typical Potential Measurements: In most environments, steel structures which are being
cathodically protected have typical potentials. Unprotected steel structures also have typical
potentials, although the unprotected structure potentials vary much more than the protected
structure potentials. A potential between -300 and -500 mV vs copper sulfate is typical of
unprotected corroding steel structures. A potential betweetr -800 and -850 mV vs copper sulfate
is typical of a structure completely protected. If-the potential is more negative than -1100 mV
then the structure may be overprotected. If the structure is overprotected, as much, or in some
cases even more damage maybe occurring than if the stntcture were unprotected.
3.5 Why and How Should Records Be KeAt?
One of the first indicators of malfunction of a cathodic protection system is a sudden change in
operating conditions such as structure potential or rectifier output. Only by keeping good records
of operating conditions can these changes be discovered promptly. The date, location, and value
of all structure potential readings should be recorded. Any maintenance performed, such as
anode replacement or repair of faulty connections should be recorded to identify trouble spots
where possible system modification maybe required.
3.6 Inspections of Structure
If sections of the pipelines are removed during maintenance inspections or other repairs, then the
effectiveness of the protection system can be determined by inspecting the structure. Gross
corrosion is, of course, indicative of system failure. The presence of deposits on the structure
should not be confused with corrosion. Calcareous deposits are formed on cathodically protected
surfaces. These deposits are often significantly lighter in color than normal rust and may even be
white. Only by removing the surface deposits and inspecting the underlying surface can a valid
assessment, of the cathodic protection of the pipelines be nisde.

4.0 Instructions, Potential Measurement
Using a suitable multimeter or voltmeter, select a scale far voltage measurements up to two volts.
Connect the negative meter lead to a portable reference ele+~trode.
Connect the positive meter lead to a test lead in a test station. Ensure that ametal-to-metal
connection is obtained. Read and record the meter display and date obtained as potential
(voltage) with respect to the reference electrode location.
Do not immerse the reference electrode terminal without the use of a special submersible adapter..
On dry soil, the soil should be moist or moistened with tap water at the cell contact point. The
meter should be a digital display type with input impedantWe of 10 meg ohms, minimum.
If an analog multimeter is used, the test lead connections must be reversed from the description
above. The reading obtained is then recorded as negative potential (-v) with respect to copper-
copper sulfate.
4.1 Instructions, Anode Output Measurement
Using a suitable multimeter or voltmeter, select a scale for voltage measurements up to 50
millivolts. Connect the meter leads across each anode skint at the junction boxes. The reading
in millivolts times 100 equals' milliamperes (.01 ohm shtitit).
4.2 Test Eauipment
The following list of equipment is a minimum requirement for the maintenance and operation of

this manual but which are required for design, installation and troubleshooting of cathodic
protection systems are not included in this list. A qualified corrosion engineer should be
consulted regarding purchase of specific cathodic protection test and maintenance equipment.
1. Meter for Structure-to-Environment Potentials
Meter Specifications:
Input impedance......10 meg ohms/volt, minimum
Range ................0 to 2 volt DC, minimum
The functions of this meter are a minimum requirement. Many meters, cathodic
protection instruments, and other high input impe~arice voltmeters may be used.
2. Reference Electrodes
a. CuCuSO4 electrode, stud type for buried of submerged structure use.
b. Reagent grade copper sulfate crystals and deionized water for replenishing
reference cell antimony (mix to obtain a saturated solution). A one-piece
instrument which combines a potential motet and reference cell in one unit is also
available. This can be used for pdrtable cathodic protection potential
measurements.
3. Lead Wires
6-foot test wires with clips - no. 16 or no. 18 stranded copper with rubber insulation.
500-foot test wires on suitable reels with clips - rin. 16 or no. 18 stranded copper with

Attention Mr. Doug Young
Subject: Cathodic Protection Survey
Dear Sir:
A cathodic Protection Survey was performed on October 15, ~t705 on the Wholesale Fuels
Facility located at 2200 E. Brundage Ln.
The system layout is as follows: the rectifier is mounted on the Borth wall of the store stockroom. The anode bed
is located at an undetermined location on the store property. TNo tank structure leads come into the rectifier from
a northerly direction; the tanks and pump units are located just Korth of the store building. In order to obtain valid
cathodic protection data the reference electrode (half cell) was placed in the dirt area located on the eastside of
the warehouse next to the chain link fence.
The cathodic protection tests were performed with an interruptoP placed in the DC circuit at intervals of 6 seconds
on and 3 seconds off. The results are tabulated in the succeedir9g pages. The tank meets the requirements for
cathodic Protection under the Code of Federal Regulations, 40 CFR Part 280. The cathodic protection levels of
protection were taken with regards to the following NACE Standards:
• RP0169-92 Standard recommended practice: Control of Corrosion on Underground or Submerged
Metallic Piping Systems.
• RP 0285-85 Standard recommended practice: Control of External Corrosion on Metallic Buried, Partially
Buried, or Submerged Liquid Storage Systems.
• STI R892-91 Recommended practice for Corrosion Protection of Underground Piping Networks
Associated with Liquid Storage and Dispensing Systems.
• American Petroleum Institute (API) Recommended Prentice 1632, Cathodic Protection of Underground
Petroleum Storage Tanks and Piping Systems.

While the Environmental Protection Agency (EPA) and local rejUlations mandate testing to be conducted on
three-year intervals to determine the effectiveness of the installed systems, experience and good engineering
practice dictate that an assessment on this type of system be mi~de on an annual basis. This, coupled with the
required monthly inspections by the W holesale Fuels personnel, will assure the continued effective operation of
the installed corrosion control systems.
The annual inspection of the cathodic protection systems sho~fld consist of structure-to-soil potential
measurements, current output of the anode bed, and a summary report to include field data and
recommendations as required.
Wholesale Fuels personnel are required to record the rectifier vt;`Itage and current meter outputs on a bi-monthly
basis using the form presented herein. Notifying qualified persdrtnel immediately should the readings vary +/-
20%frorn our initial test data noted in this report is highly recommended.
Altech appreciates the opportunity to have assisted you in this dtfort, please call us at 661-319-4760 with
questions regarding any part of this report.

SUBJECT: CLOSURE OF THE WHOLESALE FUELS, INC. SUMP, BAKERSFIELD, KERN COUNTY
COMMENTS:
I have reviewed the 15 January 1990 Closure Report prepared by Mr. Russell Juncal,
R.G. {No. 3864) of WaterWork for the Wholesale Fuels, Inc. sump.
The closure involved removing the contaminated materials from the sump, spreading
the excavated materials on site and grading the spreading area to prevent ponding,
and filling the excavation with clean soil brought from off site.
We reviewed the post-excavation soils sampling results in November 1989, and
indicated that backfilling of the excavation with clean soils could proceed. We
recommended that the area above the former sump be graded to prevent ponding and
requested that the closure report include documentation of the source of the fill
material and the results of chemical analyses of the fill material.
The Closure Report indicates the fill was obtained from the Gateway development on
Mt. Vernon (across Highway 58 from the site), and includes the results of the
chemical analyses of the soil. The analytical results indicate the metals
concentrations in the fill material are within the ranges typically found in natural
soils. There were no PCBs found in the soil at a detection limit of 0.0002 ug/g.
According to the Closure Report, the fill was transported to the sump area and
placed in the excavated area in layers approximately 2-feet thick. The lifts were
compacted with a rubber-tired loader. Upon completion of the backfill and
~compaction, the area was graded to prevent ponding. The Closure Report also
indicates that if settling is noted in the future, the area will be graded as
necessary.
The information provided in the Closure Report is satisfactory.
INSPECTION REPORT:
On 16 November 1990, I inspected the Wholesale Fuels, Inc. facility at 2200 E.
Brundage Lane, Bakersfield. I was accompanied by Mr. Terry Olgilvie of Wholesale
Fuels, Inc.
The area formerly occupied by the sump is level with the surrounding area. The
soils appeared to be well-compacted, and Mr. Olgilvie stated that a binder had been
added to the soils at the surface to reduce dust. I observed no discolored soils at
the former sump area. Maintenance of the area appeared to be adequate.

CONCLUSIONS:
The closure of the Nholesale Fuels, Inc. sump has been completed and appears to be
adequate. No further work is necessary at this time.

SUBJECT: POST-EXCAVATION SAMPLING RESULTS FOR THE WHOLESALE FUELS, INC. SUMP,
KERN COUNTY
COMMENTS
I have reviewed the post-excavation sampling results for the Wholesale Fuels, Inc.
sump in Bakersfield, California. The information was submitted by Mr. Russell W.
Juncal, R.G. (No. 3864, expiration date 6/30/g0) of WaterWork.
INTRODUCTION
Wholesale Fuels, Inc. is a petroleum jobber facility operating at 2200 E. Brundage
Lane, Bakersfield, California. As part of the facility's past operations, a sump
on the north side of the property was used as a collection area to receive rinse
water from external vehicle washing. Rainwater washing oil off drums, storm water
runoff, and possible spillage may have also entered the sump. Wholesale Fuels, Inc.
was notified by State Water Resources Control Board staff that this surface
impoundment might be subject to the Toxic Pits Cleanup Act of 1984 (TPCA).
Wholesale Fuels, Inc. demonstrated that the levels of chemicals in the sump were
not hazardous. Thus, we concluded that the sump was not subject to the TPCA.
However, as the concentrations of some of the chemicals present in the bottom of the
sump were higher than Acceptable Drinking Water Levels and were thought to pose a
threat to ground water quality, we requested that Wholesale Fuels, Inc. develop a
closure plan for the sump.
The Closure Plan for the Wholesale Fuels, Inc. sump, prepared by WaterWork, proposed
excavating the contaminated soils from the sump, spreading these soils on-site, and
backfilling the excavated area with clean soil.
According to the WaterWork letter of transmittal for the post-excavation soil
sampling results, the material removed from the sump has been spread on-site and
has been graded to prevent ponding. WaterWork also requested written authorization
to backfill the excavation with clean fill material.
POST-EXCAVATION SAMPLING RESULTS -2- 27 November 1989
FOR THE WHOLESALE FUELS, INC.
POST-EXCAVATION SAMPLING RESULTS
Eight soil samples were taken from the base of the excavation to verify that all
contaminated material was removed. These samples were analyzed for PCBs, cyanide,
and priority metals by BC Laboratories, a laboratory certified by the State for the
analyses that were performed.
The soil analyses indicated that there were no PCBs or cyanide found in any of the
samples at a detection limit of 1.0 ug/g.
The total metals concentrations measured in the sump, and after the removal of
contaminated soils from the sump, are shown in Table 1. In 2 of the 8 samples, the
detection limits were 5 times higher than the detection limits of the other samples,
so a range is given in the table.

FOR THE WHOLESALE FUELS, INC.
of metals that were found in the remaining soils are between 1.4-times and 41-times
lower than the metals concentrations originally measured in the sump.
As the table indicates, of the metals that were detected, the concentrations that
were measured in the soil samples from the base of the excavation are between 0.09
and 124 times the Acceptable Drinking Water Levels.
DISCUSSION
The sampling results indicate the metals concentrations in the soils below the sump
are between 0.09 and 124 times Acceptable Drinking Water Levels. These
concentrations are within the ranges typically found in natural soils.
Although the distance to ground water at the Wholesale Fuels, Inc. site is estimated
to be 80 feet, low levels of metals occur naturally in soils and are present
throughout the vadose zone. No soil samples were collected to determine
"background" levels of metals in the soils at the subject facility.
Nevertheless, metals tend to remain immobile and are not readily leached from soils
of neutral (pH of about 7) or higher pH (alkaline). Some metals are not even
completely soluble in weak acids. For example, although 103 mg/kg lead was measured
in the sludge contained in the Wholesale Fuels, Inc. sump, no soluble lead (< 0.5
mg/1) was detected in the extract (pH of 5.0) from the Waste Extraction Test.
The pH of the sludge contained in the sump was 7.0, and the Soil Survey of the
Bakersfield Area, California, prepared in 1945 by the Soil Conservation Service and
the University of California Agricultural Experiment Station, describes the soils
at the Wholesale Fuels Inc. site as belonging to the Pond series, and consisting of
Pond fine sandy loam. According to the Soil Survey, the Pond fine sandy loam soil
contains large quantities of lime and salts and is micaceous throughout. In the
southeastern part of Bakersfield, where the subject facility is located, the soil
is also underlain below a depth of 30 inches by a platy layer of semi-hardpan lime
accumulation. The layer is not impervious, however.
Relatively low concentrations of metals are present in the soils at the base of the
excavation, and the alkaline soil conditions at the subject facility are conducive
to retaining metals in soil. Thus, it is unlikely that water quality will be
affected by the metals in the remaining soils. Further excavation of soils,
therefore, does not appear to be necessary to protect water quality.
SUMMARY AND RECOMMENDATIONS
After reviewing the post-excavation soil analytical results for the Wholesale Fuels,
Inc. sump in Kern County, I have developed the following summary and recommendations:
1. The sampling results indicate that there were no PCBs or cyanide found in any of
the samples at a detection limit of 1.0 ug/g.
POST-EXCAVATION SAMPLING RESULTS -4- 27 November 1989
FOR THE WHOLESALE FUELS, INC.
Following excavation, the concentrations of metals found in the remaining soils
were between 1.4-times and 41-times lower than the metals concentrations
originally measured in the sump, and are between 0.09 and 124 times the
Acceptable Drinking Water Levels. Although no "background" soil samples were
collected, the concentrations of metals are within the ranges typically found
in natural soils.
Because relatively low concentrations of metals are present in the soils at the
base of the excavation, and the alkaline soil conditions at the subject facility
are conducive to retaining metals in soil, it is unlikely that water quality will
be affected by the metals in the remaining soils.
Further excavation of soils is, therefore, not necessary to protect water
quality, and backfilling of the sump with clean fill material should be allowed
to proceed.
2. As requested in our review of the Closure Plan for the sump, documentation
regarding the source of the clean fill dirt that is to be used to backfill the
sump and the results from chemical analysis of the fill dirt need to be included
in the final closure report.
Upon completion of the backfilling and compaction, the area of the sump should
also be graded to conduct storm runoff away from the sump. The grade should be
of a sufficient slope to'prevent ponding over the backfilled sump.
A review of the grading should be conducted one year after the completion of
the backfilling of the sump to check for settling.
