XV. IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM CONTINUITY SURVEY
This section may be utilized to conduct measurements of continuity on underground storage tank systems that are protected by cathodic protection systems.
When conducting a fixed cell - moving ground survey, the reference electrode must be placed in the soil at a remote location and left undisturbed.
Conduct point-to-point test between any two structures for which the fixed cell - moving ground survey is inconclusive or indicates possible isolation.
For impressed current systems, the protected structure must be continuous with all other protected structures in order to pass the continuity survey.

XVI. IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM SURVEY
This section may be utilized to conduct a survey of an impressed current cathodic protection system by obtaining structure-to-soil potential measurements.
The reference electrode must be placed in the soil directly above the structure that is being tested and as far away from any active anode as practical to obtain
a valid structure-to-soil potential.
Both on and instant off potentials must be measured for each structure that is intended to be under cathodic protection.
The instant off potential must be -850 mV or more negative or the 100 mV polarization criterion must be satisfied in order to pass.

COMMENTS: STRUCTURE WIRING DOES NOT MEET MINIMUM CONTINUITY REQUIREMENTS. SHOWS TANKS NOT PROPERLY
CONNECTED TO RECTIFIER. ADDITIONALLY, THERE IS INSUFFICIENT CURRENT DISTRIBUTION DUE TO ANODE DEPLETION (WE
RAN A TEMPORARY STRUCTURE JUMPER BETWEEN RECTIFIER NEGATIVE AND FILL RISERS). DOES NOT MEET STI
REQUIREMENTS FOR PROTECTION. REQUIRES NEW STRUCTURE WIRING AND ENGINEERING DESIGN OF NEW ANODE
GROUNDBED, INSTALLATION OF ANODE GROUNDBED, AND COMMISSIONING TO BRING IT BACK INTO COMPLIANCE.
1 Designate numerically or by code on the site drawing each local reference electrode placement (e.g. 1,2,3 T-1, T-2, P-1, P-2etc.).
2 Describe the structure that is being tested (e.g. plus tank; diesel piping; flex connector, etc.).
3 Describe where the structure being tested is contacted by the test lead (e.g. plus tank bottom; diesel piping @ dispenser 7/8; etc.).
4 Describe the exact location where the reference electrode is placed for each measurement (e.g. soil @ regular tank STP manway; soil @ dispenser 2, etc.)
5 {Applies to all tests} Record the structure-to-soil potential (voltage) observed with the current applied (e.g. –1070 mV).
6 {Applies to all tests} Record the structure to soil potential (voltage) observed when the current is interrupted (e.g. 680 mV).
7 {Applies to 100 mV polarization test only} Record the voltage observed at the end of the test period (e.g. 575 mV).
8 {Applies to 100 mV polarization test only} Subtract the final voltage from the instant off voltage (e.g. 680 mV – 575 mV = 105 mV).
9 Indicate if the tested structure passed or failed one of the two acceptable criteria (850 instant off or 100 mV polarization) based on your interpretation of data.

ATTACHMENT A – REFERENCE ELECTRODE CALIBRATION TEST PERFORMED

Copper-Copper Sulfate reference electrode field calibration test (half-cell)

The following reference electrode calibration test was performed:

Visual inspection: The field reference electrode should always have a quantity of undissolved copper
sulfate crystals present in the solution to assure that the solution is saturated. The solution should be
azure blue and clear since contaminants can make the solution cloudy.

Parts required to perform field calibration test:

QUANTITY DESCRIPTION

HALF CELL –
CALIBRATION STANDARD – NOT USED IN FIELD
1 COPPER-COPPER SULFATE CuCu/SO

HALF CELL –
TO BE CALIBRATED – FIELD REFERENCE ELECTRODE

INSTRUCTIONS:
1. Place both the CALIBRATION STANDARD – NOT USED IN FIELD half-cell and the half cell to be
calibrated into a container of distilled water.
2. Connect the half-cells to the leads of a voltmeter capable of giving reading in mill volts.
3. Turn on the voltmeter and see if the voltmeter reads a potential difference of (+/-) 10mV or more.
4. Wait up to five (5) minutes.
5. If half-cells show 10mV or more difference of potential, the half-cell being calibrated is out of
calibration and should be replaced or cleaned and re-checked.

ATTACHMENT B – FLUKE MULTIMETER CALIBRATION

The following equipment shows the Fluke Multi-meters used for testing of CP potentials for these surveys:

Multi-meter Model Number Serial Number
Fluke 177 10970562
Fluke 87V 97320326
Fluke 177 92130748
Fluke 87 61140311
Fluke 87III 72150542
Fluke 77 66830417

The 77, 87, 175, 177, & 179 Manufacturer’s Calibration Information provides the information necessary to
adjust and verify the performance of the Fluke Models 175, 177, and 179 True RMS Multi-meters.

WE PERFORM A PERFORMANCE TEST ON THESE DEVICES MONTHLY (within the last 30 days):
The performance tests verify the operation of the Meter when measuring low voltage DC potentials, such
as those encountered during a CP survey. We check the accuracy of each Meter function against its
specifications as referenced to a precision, stable, low-voltage supply reference that is accurate to within
0.007% (plus or minus 350uV) as measured by a calibrated 8.5 digit Keysight 3458A DMM that has an
accuracy of 0.0008% (Keysight Technologies, Loveland Standards and Calibration Labs Certificate of
Calibration 1-7581424013-1, (valid through January 21, 2023). If the Meter fails any part of the test per
specifications of the manufacturer (+/- .09 volt @ 5 VDC ), calibration adjustment and/or repair is
indicated it is sent to the manufacturer for repair and or calibration.

WE PERFORM A CALIBRATION ON THESE DEVICES MONTHLY (within the last 30 days):
Calibration test of multi-meters was performed against its specifications as referenced to a precision,
stable, low-voltage supply, as indicated above.
