1.0 Introduction
The Defense Logistics Agency - Energy (DLA-Energy) through the U.S. Army Corps of
Engineers, Charleston District, contracted Corrpro to conduct cathodic protection (CP)
surveys. This CP survey includes all DLA-Energy capitalized assets for petroleum, oil,
and lubricant (POL) storage and distribution at Dugway Proving Ground, Tooele County,
UT. The intent of this survey is to determine: the condition of existing CP systems; if DLA-
Energy fuel transfer and storage assets meet NACE International criteria for CP; and if
any structures require a new system or upgrade to an existing CP system.

Mr. Brooks Bucher is Corrpro’s project manager. The survey was conducted during
October 24 and 25, 2022, by NACE certified Senior Corrosion Technologist Mahsa
Bakherad and NACE Certified Cathodic Protection Technician Alex Rosen. This report
has been prepared by Mahsa Bakherad and reviewed by Yash Mir, NACE certified CP
Specialist.

4.1 Bulk Fuels Storage
English Village Area
Above Ground Storage Tanks (ASTs) 5660 and 5661 are each 25-foot diameter on-grade
ASTs with a nominal capacity of 125,000 gallons containing diesel fuel. The facility
drawings, as shown in Appendix B, indicate the tanks are constructed with a concrete
ring wall foundation. The tanks have individual earthen berms covered by a flexible
containment liner as seen in Figure 1.

Figure 1 – AST 5660 & AST 5661 and Aboveground Fuel Pipes

Dugway Proving Ground
2022 Annual Survey
Corrpro Project 340532208 7 DUG 22-CP
The exterior surfaces of the steel plates under ASTs 5660 and 5661 receive corrosion
control from a single ICCP system installed in 2009, see Figure 2. This ICCP system for
both tank bottoms is powered by one 50-volt / 5-amp air-cooled; voltage tap-adjust
rectifier. Adjacent to the rectifier is an Elecsys Watchdog Scout RMU which can
additionally be used to interrupt the system. A three-circuit MMO anode ground bed
installed between the tank floor and the dielectric liner is 0.118-inch diameter MMO anode
wire installed in a loop pattern. Three stationary copper-copper sulfate reference
electrodes (CSEs) were installed under each tank bottom. Lead wires from the MMO
anodes and CSEs terminate in an anode/testing junction box located adjacent to the
RMU, see Figure 3. The drawings in Appendix B illustrate the layout of the ICCP system.

Figure 3 – English Village AST 5660 & AST 5661 ICCP System Junction Box
Fuel is distributed to and from the tanks via truck racks located on the north and east
sides of the fuel farm facility. The issue and receipt piping connecting ASTs 5660 and
5661 to truck stands are 4 inches in diameter, stainless steel, and aboveground, except
for cased sections through the earthen containment berm, see Figure 4. The fuel-carrying
piping is not in contact with soil and therefore does not require CP.

Corrpro Project 340532208 9 DUG 22-CP
Ditto Area
Tanks 4056 and 4057 in the Ditto Area are 14-foot diameter on-grade Jet A fuel ASTs,
each with a nominal capacity of 25,000 gallons, see Figure 5. Each tank rests on a
concrete ring wall foundation containing a sand pad surrounded by a vertical concrete
containment wall. There is no secondary containment liner beneath either tank.

Figure 5 – AST 4056 & 4057 and CPTS on White PVC Posts
Fuel piping connects a truck stand to filter pumphouse 4055 and the AST’s. This 4-inch
diameter fuel piping is aboveground and does not require CP.
An ICCP system, installed in 2008, provided corrosion control to the tank bottom of ASTs
4056 and 4057. The 10-volt/15-amp air-cooled rectifier installed in 2008 was replaced
with a 40-volt/42-amp air-cooled rectifier in 2018 (shown in Figure 6). The rectifier is
equipped with a Watchdog Scout RMU with interruption capabilities. This rectifier
powered by a distributed vertical anode groundbed with six tubular high silicon cast iron
canister anodes (HSCI). This anode groundbed was found non-operational in 2019 and
is no longer providing CP current.
In June 2022, a new distributed anode groundbed was installed around the outside of the
containment area. The new groundbed consists of eight, 12-ft deep holes each containing
one 70-lbs (84-inch long by 2.7-inch diameter) tubular HSCI anode with No.8 HMWPE
wire in an active column of 10-ft filled with SC-3 Loresco coke breeze. The anode holes
are located around the ASTs enclosure with two on the east side, two on the west side,
and four on the south side which can be seen in Figure 7. Lead wire from each of the
anodes are routed to a new anode junction box adjacent to the rectifier (see Figure 8).

4.2 Motor Pool Facilities
Facility 5469 at English Village
The Motor Pool Facility 5469 contains one diesel UST and one MOGAS UST, each with
dedicated fuel dispensers. This facility is located to the west of Building 5468, near the
English Village area and on Stark Road, see Figure 10.

Figure 10 – English Village Motor Pool Area
UST 1 (MOGAS) was manufactured in 1988, it is 23 feet and 8 inches in length, has a
12-foot diameter, and has a nominal capacity of 20,000 gallons. The tank is constructed
of double-walled steel and contains MOGAS fuel. UST 2 (diesel) was manufactured in
1988, is 26 feet 8 inches in length, has an 8-foot diameter, and has a nominal capacity of
10,000 gallons. The tank is constructed of double-walled steel and contains diesel fuel.
UST 1, containing MOGAS, was manufactured with direct connect galvanic anodes and
in 2018, a supplemental galvanic CP system was installed, which consisted of four 32-
lbs. prepackaged high-potential magnesium anodes, two new structure cables
exothermically welded to the exterior of the tank, and a new test station. A coupon suitable
for IR-free potential measurements is buried near the UST. Wires for the tank test leads,
anode lead, and coupon are terminated in a test station with a 0.1 ohm red Cott shunt for

Dugway Proving Ground
2022 Annual Survey
Corrpro Project 340532208 13 DUG 22-CP
anode current measurements. The anodes were installed horizontally on the north and
east sides of the tank at a depth of approximately 8 feet.
UST 2, containing diesel, was manufactured with direct connect galvanic anodes and has
a supplemental galvanic CP system consisting of three magnesium anodes connected to
the tank through a 0.01-ohm RS wire shunt and a dedicated structure connection. The
size and date of installation for the supplemental CP system on UST 2 could not be
confirmed.
There are three soil access ports surrounding each tank for CP measurements.
The underground piping that connects UST 1 and 2 to the fuel dispensers is constructed
of double-walled fiberglass. These nonmetallic pipes do not require CP.
Facility 4135 at Ditto Area
The Motor Pool Facility 4135 consists of two USTs (one for MOGAS and one for diesel
storage). Each UST has a dedicated fuel dispenser located to the north of the tanks. The
facility is located near the Ditto Area off Stark Road on Third Street, as shown in Figure
11.

UST 1 (MOGAS) was manufactured in 1999, is 23 feet 8 inches in length, has a 12-foot
diameter, and a nominal capacity of 20,000 gallons. The tank is constructed of double-
walled fiberglass and contains MOGAS fuel. UST 2 (diesel), manufactured in 1999, is 26
feet 8 inches in length, has an 8-foot diameter, and a nominal capacity of 10,000 gallons.
The tank is constructed of double-walled fiberglass and contains diesel fuel. The
underground piping that connects the USTs to the fuel dispensers is constructed of
double-walled nonmetallic material (EnviroFlex). An overview of this area can be seen in
Figure 12.

Figure 12 – Facility 4135
The USTs and fuel piping are non-metallic, and therefore do not require cathodic
protection. These structures will not be mentioned further in this report.

5.0 Test Procedures
Testing was performed in accordance with Corrpro test procedures and NACE
International Standard Test Methods. A brief synopsis of the test methods employed
include the following:

 Rectifier Inspection – The rectifiers at the facility were assessed for physical and
electrical damage, meter accuracy, and general operating condition. The electrical
disconnect and grounding were inspected to ensure they were in good condition.
Notes were also made about the seasonal condition of the soil (dry, wet, or frozen),
as these parameters can have a marked influence on groundbed operation. Where
rectifier-output monitoring data was available, this was also reviewed to determine
if any tendency for deteriorating performance was evident.
 Structure-to-Soil Potential Measurement – Structure-to-electrolyte potential
testing was the primary method used to evaluate cathodic protection levels.
Testing was carried out using a high-impedance voltmeter and a calibrated
portable copper-copper sulfate electrode (CSE) and a stainless-steel contact
probe. To take measurement, the CSE was placed in contact with suitable soil
(electrolyte) overtop or near the structure being examined. A connection was made
to the structure being tested to complete the circuit through the voltmeter. For ICCP
systems, the current from the influencing rectifiers was simultaneously interrupted
to allow IR-free measurements.
 Depolarized Potential Measurement – All sources of CP current that affected the
tested structure were left off for at least 24 hours. After that time, a structure-to-
electrolyte potential measurement was taken. This value was then used to calculate
the amount of polarization a structure was receiving.
 Anode Current Output – Galvanic anode current output was calculated by
measuring the IR-drop across a permanent shunt of known resistance, installed in
series with the anode and applying Ohm’s Law. The same method was used for
impressed current anode circuits or an amp clamp instrument was used to
measure direct current.
 Electrical Isolation – Many CP systems rely on effective electrical isolation for
correct operation. Flange electrical isolation was verified using potential
measurements on both sides of the isolation and using a Gas Electronics Flange
Isolation Checker to identify faulty hardware.
 Impressed Current CP (ICCP) System Assessment – Five parameters were
evaluated to assess CP on assets protected by ICCP systems:

Dugway Proving Ground
2022 Annual Survey
Corrpro Project 340532208 16 DUG 22-CP
o Rectifier performance
o Groundbed performance (resistance, anode output and soil condition)
o Structure-to-soil on or energized potential
o Structure-to-soil instant-off or polarized potential
o Structure-to-soil depolarized or native potential
 Galvanic CP System Assessment – Six parameters were evaluated to assess
CP on assets protected by Sacrificial Anode Cathodic Protection Systems:
o Anode current output (collective and/ or individual)
o Open Circuit Potential (OCP) of the anode(s)
o Structure-to-soil On or energized potential
o Structure-to-soil Instant-off or polarized potential
o Structure-to-soil depolarized or native potential
o Effectiveness of installed electrical isolation kits and fittings.

Rectifier data, potential measurement data, and all other relevant survey data are
included in Appendix A. The cathodic protection systems’ effectiveness was determined
by evaluating these data with respect to NACE International criteria and the other
referenced standards.

6.0 Findings
6.1 Bulk Fuels Storage
English Village
The rectifier was found in good condition and operating at 9.33 volts and 2.37 amps. Each
of the six anode circuits under the two ASTs was discharging a protective current. The
RMU unit was in good condition and operational.
The measured S/E potential data indicated both ASTs 5660 and 5661 were receiving an
adequate level of cathodic protection meeting the NACE International SP0193-2016,
“100 mV of cathodic polarization” criterion.
The calculated cathodic protection current densities for tank bottoms 5660 and 5661 are
2 and 2.5 mA/ft2 respectively. Cathodic protection current densities for AST bottoms are
typically in the range of 0.5 to 1.0 mA/ft2.
The testing data is tabulated in Appendix A.
Ditto Area
The rectifier was found in good condition and operating at 6.09 volts and 30.7 amps. The
newly installed anode groundbed in June 2022, was effective and each of the eight
anodes was discharging CP current, as designed. The RMU unit was in good condition
and operational.
Tank S/E potential measurements were measured at the test stations located at the
ASTs. Potential data indicates both AST 4056 and 4057 were receiving an adequate level
of CP, meeting the NACE International SP0193-2016, “100 mV of cathodic polarization”
criterion.
The testing data is tabulated in Appendix A.
6.2 Motor Pool
Facility 5469 at English Village
Both the diesel and Mogas USTs are electrically isolated from each other and have their
own respective galvanic CP system. Each UST has its respective test station which
houses lead wires for the anodes and the tank structure connection. The lead wires are

Dugway Proving Ground
2022 Annual Survey
Corrpro Project 340532208 18 DUG 22-CP
connected through a 0.1-ohm wire shunt for MOGAS UST and a 0.01-ohm wire shunt for
Diesel UST. See Figure 13 and Figure 14.

Figure 13 – MOGAS UST Test Station

Figure 14 – Diesel UST Test Station
MOGAS UST
The S/E “Off” potentials were measured at north, south, and east through the soil access
ports for this UST. The measured data indicates the UST was receiving an adequate level
of CP meeting “a negative polarized potential of at least -850 mVCSE” per NACE SP0285-
2021. The measured current output of the CP system was about 3.6 mA. All four galvanic
anodes were still efficient and were providing CP current to the target structure. The
potential measurement on the electrical grounding indicates this tank was electrically
isolated from the electrical grounding. The testing data is tabulated in Appendix A.

Dugway Proving Ground
2022 Annual Survey
Corrpro Project 340532208 19 DUG 22-CP
DIESEL UST
The S/E “Off” potentials were measured at north, south, and west through the soil access
ports for this UST. The measured S/E “Off” potentials around the diesel UST satisfied the
NACE SP0285-2021 CP criterion of -850 mVCSE or more negative polarized potential for
receiving adequate CP. The measured current output of the CP system was about 2.2
mA. Potential testing data indicates the UST was electrically isolated from the grounding
system. One of the four galvanic anodes was depleted and its lead wire was taped and
left disconnected from the terminal board. The rest of the anodes were effective. The
testing data is tabulated in Appendix A.
