repaired before installation. After field coating and wrapping has been
applied, the entire pipe shall be inspected by an electric holiday detector
with impressed current in accordance with NACE RP0188 using a full ring,
spring type coil electrode. The holiday detector shall be equipped with a
bell, buzzer, or other type of audible signal which sounds when a holiday
is detected. Holidays in the protective covering shall be repaired upon
detection. Occasional checks of holiday detector potential will be made by
the Contracting Officer to determine suitability of the detector. Labor,
materials, and equipment necessary for conducting the inspection shall be
furnished by the Contractor. The coating system shall be inspected for
holes, voids, cracks, and other damage during installation.

Recording Measurements
All [pipe-] [tank-] to-soil potential measurements including initial
potentials where required shall be recorded. The Contractor shall locate,
correct and report to Contracting Officer any short circuits to foreign
[pipes] [tanks] [_____] encountered during checkout of the installed
cathodic protection system. [Pipe-] [Tank-] [_____] to-soil potential
measurements are required on as many [pipes] [tanks] [_____] as necessary
to determine the extent of protection or to locate short-circuits.
3.6
TRAINING COURSE
The Contractor shall conduct a training course for the operating staff as
designated by the Contracting Officer. The training period shall consist

tests. The field instructions shall cover all of the items contained in
the operating and maintenance instructions, as well as demonstrations of
routine maintenance operations, including testing procedures included in
the maintenance instructions. At least 14 days prior to date of proposed
conduction of the training course, the training course curriculum shall be
submitted for approval, along with the proposed training date. Training
