top soil wilt be placed back in its original location. Under
no circumstance shall the top soil be mixed with undesirable
materials.
In areas where sufficient rock is encountered or where
Inspector deems necessary the Contractor at its expense will
pad the ditch with sand or a dirt pad free of rocks, hard
clods, or foreign material at fifteen (15') foot intervals
sufficient to support the pipe six (6") inches above the
bottom of the ditch. The pipe shall be covered with dirt free
of rock to a depth of six (6") inches above the pipe.
If suitable dirt for padding is not readily available along
the pipeline right-of-way then the Contractor shall provide
and haul in from another location sufficient quantities of
padding materials as required. Oirt will not be procured by
sloping the shoulder of the ditch and backfilling will be done
in accordance with the Technical Specifications, Section 1.11.
Spoil Bank - The spoil excavated from the ditching operations
shall not be allowed to mix with loose debris or foreign
matter.

being placed in the line. If the ends of the pipe are damaged
to the extent that satisfactory welding contact cannot be
obtained, the pipe shall be cut and beveled to the satis-
faction of the Inspector. The cost of beveling any joint
shall be borne by the Contractor unless it is determined that
the damages occurred prior to the Contractor's accepting the
custody of the pipe. Such defects are required to be clearly
noted on the pipe tally and signed by the Contractor's
representative and the Company's representative at the time of
the material custody transfer. This note shall contain the
type of damage (i.e., bad bevel or buckle) and the footage of
pipe which is rendered useless because of the damage. No
repair welding shall be performed on the longitudinal seams of
any pipe.
Weather Conditions Welding shall not be permitted when
weather conditions are unsatisfactory and would impair the
quality of welds. No welding shall be done if in the opinion
of Inspector high winds, rain, snow, dust, or sandstorms are

weathering or by any other cause may be rejected by Company.
All coating shall be applied in accordance with the manu-
facturer's instruction.
1.8.2
The joints within any concrete coated pipe will be field
coated with the above specified material. The joint wire will
then be tied as shown on the included Pipeline Standard ML-8.
After the wire has been tied the joints will be formed and
grouted with 3000 lb. grout.
1.8.3
Cteanin9 - In preparation for the application for primer, the
pipe shall be cleaned with a wire brush and then with a
non-volatile solvent until free from all loose mill scale,
rust scale, corrosion, pipe coating, dirt, grease, moisture or
other foreign material. The coating shall be applied
immediately after the solvent has dried.
1.8.4
-Primin9 and Taping - The primer shall be applied immediately.
after the cleaning operation in a thin, uniform coating
leaving no drips or runs and covering the entire surface of
the pipe. Freshly primed pipe shall be supported so that it
will not come in contact with dirt and weeds. After the
primer coat has set the primed area shall be spiral wrapped
with one layer of tape sufficiently tensioned to provide a
firm, smooth bond to the primed pipe. The tape shall be
applied so that each wrap of tape overlaps the previous spiral
by I inch. Spiral wraps shall overlap the existing coating a
minimum of 3 inches on each end. The spiral shall be started
and ended with a wrap which is square with the length of the
pipe. The tape shall not be applied at temperatures below the
minimum application temperatures recommended by the manu-
facturer. All pipe which is primed shall be wrapped the same
day.
1.8.5
Care and Handlin9 of Coated Pipe Coated pipe shall be
handled at all times with wide, nonabrasive, rubberized canvas
belts or other equipment approved by the Inspector. The use
of tongs, bare pinch bars, chain slings, rope slings, canvas
or composition belt slings with protruding rivets, pipehooks,
or any other handling equipment that may damage the coating or
the bevel shall not be permitted. Yard-coated pipe shall be
unloaded and handled in such a manner as to protect the
coating from damage at all times.

excluding the concrete coated pipe, will be tested with a
holiday detector furnished and operated by the Contractor in a
manner acceptable to the Inspector. The Inspector will
specify the voltage setting of the holiday detector prior to
jeeping. All coating defects indicated by the holiday
detector, damaged areas, and holes in the coating shall be
repaired by the Contractor. The coated and wrapped line shall
be immediately lowered into the ditch. Coating damage shall
be noted on the material transfer when possession is taken by
the Contractor.
1.8.7
Repairs - All holidays and damaged coating shall be repaired
by removing all loose coating materials and cleaning and
applying primer and tape as described in the applicable
sections. When making repairs, the tape should overlap the
damaged area by 1 inch. A full wrap of tape shall be made
around the circumference of the pipe and the ends of the tape
shall overlap each other by 3 inches.
1.9
Layin9 and Lowering-In
1.9.1
Closing Ends of Line - The open ends of the line shall be
securely closed at the end of each day's work to prevent the
entrance of water, small animals, trash or any other
obstructions and shall not be opened until work is resumed.
1.9.2
Lowering and Obtaining Slack - The line may be lowered into
the ditch following radiographic testing of every weld, joint
coating operations and after holiday detection. No slack
loops will be permitted in the pipeline. The Contractor may
employ any acceptable means of lowering provided that such
means will secure the necessary amount of slack uniformly
distributed in the bottom of the ditch and does not damage the
pipe or protective coatings. When lowering the line into the
ditch the Contractor shall support the pipe so as to provide
for necessary slack. Before lowering pipe into the ditch all
skid marks and other damaged places shall be repaired. Excess
slack, if any, shall be removed by the Contractor by cutting
out as requested by the Inspector and rewelding, the resulting
two ends of the line together. A nonabrasive, rubberized
canvas sling sufficiently long and wide so that no metal part
can touch the coated pipe, or a wheel with rubber tires shall
be used in lowering all coated pipe sections. The necessary
amount of slack must be obtained without damage to the pro-
tective coating. In removing the sling a bell hole shall be
dug, if necessary, so that no part of the sling will damage
the coating.
1.10

providing no rock is piled on top or near the top of the ditch
in such a way as to add to the difficulties of plowing,
cultivating, or grading. All surplus rock removed from the
ditch shall be disposed of by the Contractor to the satis-
faction of the Inspector. In all areas the final appearance
of the right-of-way after final cleanup must be the same as
the general surrounding terrain. No rock will be left p-
rotruding from the surface within the ditch area along the
right-of-way.
Site inspections by the Inspector will determine whether
excavated material is suitable for backfill. ,If backfill is
determined unsuitable the material will be removed from the
site.
Backfill on Slopin9 Ground - When backfilling hillsides or
sloping ground the Contractor shall provide furrows or
terraces across the pipeline ditch as requested by the
Inspector to direct the flow of water into natural drainage
courses and away from the pipeline ditch.
Backfillin9 Over Coated Pipe - Backfilling shall be accom-
plished in a manner approved by Inspector such that no rocks,
hard clods, or other hard objects will be permitted to fall on
the coated pipe; the pipe shall be covered with 6" of sand or
suitable material before any rocks or hard objects are put
into the ditch.
The Contractor shall provide additional compaction as needed
to minimize settling of backfill.
No Trash to be Thrown into Ditch - Throwing of foreign
substances or refuse of any kind into the ditch will not be
permitted. All such materials and refuse must be removed from
the right-of-way by the Contractor, to the satisfaction of the
Inspector.
Cleanup of Right-of-Way - As soon as backfill is completed,
the Contractor shall immediately clean up the right-of-way by
removing all defective materials and disposing of all refuse
to the complete satisfaction of the Inspector. Insofar as
