Project Number 101020172
March 11, 2005
This Project Plan describes work to be performed by Puget Sound Energy and/or its contractor
("PSE") and the City of Auburn and/or its contractor ("City") for the conversion of
certain PSE electrical distribution system facilities as described herein (the "Conversion Project").
In addition to this document, this Project Plan includes and consists of:
· Relevant drawings and specifications for the Conversion Project work
· Relevant PSE Standards for installation ofPSE facilities
· Project Cost Estimate document(s)
Revisions to this Proiect Plan must be mutuallv aQDroved bv the City and PSE.
Conversion Proiect Scope
Pursuant to PSE's Schedule 74, PSE will convert its existing overhead distribution system of
15,000 volts and less to an Underground Distribution System within the following area (the
"Conversion Area"): A total of 150 trench feet along the south side of 3rd St. SE from Sta. 1 + 20R
easterly to the intersection of "A" St. SE, Sta. 3+50R. A total of 330 trench feet along the west
side of "A" St. SE from approximate Sta. 5+50L south to Sta. 2+20L. An approximate total of
80 trench feet across "A" St. SE from approximately Sta. 2+70 to Sta. 3+50. This is an
approximate total of 425 trench feet. The Conversion Project includes modification or
replacement of all existing service lines within the Conversion Area to Connect to the
Underground Distribution System and removal ofPSE's existing overhead distribution facilities
from the Conversion Area. Refer to project drawings for PSE Work Order 101020172.
Operatin2 Ri2hts
The existing overhead distribution facilities are located within the Public Thoroughfare except
as indicated below under "Overhead Distribution Facilities Not Within Public Thoroughfare".
The Underground Distribution System will be located within Public Thoroughfare, except for
facilities at locations T02 - Sta. 1 +60R, and T03 - Sta. 5+55L. Sufficient Space is not available
within existing Public Thoroughfare at these locations. Unless otherwise mutually agreed,
operating rights to provide Sufficient Space for these two locations will need to be acquired
pursuant to Schedule 74 Section 3 prior to the start of Conversion Project construction.

Overhead Distribution Facilities Not Within Public Thoroughfare
The existing overhead distribution facilities along the Shell property's frontage on 3rd Street are
outside the Public Thoroughfare. PSE has an existing easement for overhead elec:trical facilities
over the north 10 feet of tax parcel 395390-0005 (the Shell property). PSE also has an existing
easement for underground electrical facilities over the west 10 feet of the north 10 feet of the
Shell property. Both easements were granted in the document recorded in King County under
Auditor File No. 20020124000409. The City is acquiring additional right of way along the Shell
property's frontage on 3rd Street, subject to PSE's existing easement.
The proposed facility at T02 requires a 10' x 10' space on the northwest comer of the Shell
property, behind the future right of way line. After the right of way acquisition, PSE's existing
10' x 10' underground electrical easement will be reduced by approximately 1.56' along its north
side. Therefore, the City and PSE have mutually agreed as follows:
1) The City agrees to negotiate for and acquire a new 10' x 10' underground electrical easement
on the northwest comer of the Shell property. The new 100 square foot easem4mt will be on
PSE's form and will provide adequate operating rights for the proposed facility at T02.
2) As part of this project PSE agrees to release the existing 10' x 10' underground electrical
easement granted in AF# 20020124000409.
3) Once all overhead electrical facilities have been removed from the Shell property, the City
and/or the property owner can request PSE release the overhead electrical portion of the
easement.

facilities and is not required for the new underground electric distribution system, the cost for
such support will be detennined based on the existing franchise agreement between the City and
PSE.
Whenever the requirement for temporary pole support is due to the installation of other than City
owned facilities not covered by the aforementioned franchise agreement and is not rl~quired for
the new underground electric distribution system, the cost will be borne by the person or entity
requesting or requiring such support.

----
Scope
This standard provides the requirements for installing protective guard posts around Poget
Sound Enetgy's padmount transformers and switchgear that are exposed to vehicular traffic
or moving machinery. It is a WAC requirement that all transformers that are installed in an
area which is subject to vehicular traffic be provided with adequate gu.arding.
See Standard Practice 6775.0035 for working and operating clearance requirements around
padmount transformers and switchgear. .
Responsibilities

· Pay Poget Sound Energy's cost to furnish and install them on the .;:ustomer's behalf.
Requirements
Control ZOne
Padmounted equipment and guard posts shall "ot be located within control zone areas.
Contact the municipalities traffic engineer to determine the control zonc~ requirements.
Clearances
Guard posts are required when a padmounted transformer or switchge&l' is exposed to
vehicular traffic and 5 feet of clearance cannot be maintained between the equipment pad and
the vehicles.
Qearances are measured from the transformer's conaete pad to the edge of the driving
sUlface used by vehicular traffic (parking lots, alleys, driveways, or roadways). (See Figure
1.)
exception
If a transformer is located next to a parking stall where vehicles park beside the transformer
in such a way that the vehicle's bumper does not overhang towards the transformer, and there
is a ani> between the transformer and the parked car, then the clearance in the direction of the
parked vehicles may be reduced to 18 inches.

Installing Street Light Tubes
Street light tubes are corrugated plasitc culvert pipe used to provide a hole for setting the
street light pole at a future date. Do lIot use ctUYlboartl tubes because moisture will
disintegrate them.
The developer should supply street light tubes with diameters and lengths shewn in Table 1.
Street light tubes should be installed so that the top of the tube is 2-3..in. below final grade.
NOTES
· Smaller diameter tubes do not allow room to train the ClC into the pole and do not
provide enough space for backfill and tamping.
· Measure the depth of the street light tube to the proposed finished grade and compare to
the required pole setting depth. If necessary, backfill and tamp UIltil correctly installed to
the finished depth requirement. It may be necessary to hand dig inside the street light
tube if it is too shallow.
Procedure
Follow these steps to install street light tubes.
1 O1t a 3-in. x 6-in. slot in the street light tube, starting 2O-in. :from the top edge
(Figure 4).
2 Install the street light tube into the hole where the street light will be located. The
top of the installed tube should be 2-3-in. below final grade. Orient tube so that slot
will be as shown in Figure 4.
3 Install the ClC in a gradual bend from the trenchline up into 1the slot in the street
light tube. Firmly support the ClC with backfill. Extend the CIC 5-ft above the top
of the street light tube. Seal the ClC with a conduit cap.
4 Secure the street light tube by attaching a piece of plywood or a lid to the opening.
Provide a hole in the lid to feed the ClC through. Cut off one foot of the ClC to
expose 1-ft of conductor. Fold conductor back along the outsilde of the ClC and
securely tape the conductor to the ClC to prevent the conduct:or from being pulled
back into the ClC.
5 Continue with the circuit wiring procedure.

pulled out of the conduit, and the edge of the conduit will not catch as you feed it
into the pole.
NOTE: Leave sufficient wire to provide . 18-iD.. of wire outside tile access plate
opening.
2 If necessary, bacldi11 the bottom of the street light tube with SI8-in. minus gravel so
that the ground line on the installed pole will be at grade.
3 Slowly lower the pole into the street light tube. Guide the excess wire and ClC into
the pole's cable entrance hole and out of the access plate opening (Figure 5). When
the pole is completely lowered into the street light tube, conduit ~lhou1d be viSIble
below the access plate opening (Figure 2). Allow 18-in. of wire to fuse the
luminaire in the access plate opening (Figure I, Fuse Detail).
4 Set the pole. Backfill with SI8-in. minus gravel, and compact in ti-in. lifts. Set the

Vault, Handhole, and Padmounted
Equipment Location
------
Scope .
This standard covers the factors that must be considered in choosing allocation for a vault,
handhole, or padmounted piece of equipment. It does not address the llocation of cables or
conduit.
Definitions
These are definitions of terms used in this standard:
Government Entity
A city, county, or state entity that has ;authority over the
Public Thoroughfare in the conversioIl or relocation area.
A publicly owned road, right-of-way or real property that
allows for electric utility use.
Vaults, handholes, junction boxes, padlmounted
transformers, padmounted switches, submersible
transformers, and submersible switches.
Public Thoroughfare
Underground Equipment
Location Requirements
Accessibility Underground Equipment must be readily accessible by workers and equipment during
construction and for future operation and maintenance. Workers should not have to c1imb
over or remove obstacles to gain access. Heavy construction equipment must be able to get
close enough to the excavation to place the vault in the hole. Consider the underground
equipment's weight and the lifting angle and swinging radius of the boom truck when
choosing the underground equipment's location. Remember that dump trucks may need
access if select fill is used for fill or if excavated material will be hauled away.
Working Space
A clear and level working space is necessary for the operation and maintenance of
Underground Equipment (Figures 1-6). The location must allow room to operate a switch
handle, completely open a hinged steel door, or use a hotstick to install and operate
equipment. In no case shall clearances be less than those required by code from combustible
and noncombustible walls, bodies of water, fire escapes, etc. (see Standard Practice
0700.1500, "Clearances for Oil-Filled Equipmenf').
The working space should be free from obstructions such as trees, shrubbery, poles,
buildings, retaining walls, structures, fences, fire hydrants, decorative 5:aeens, ditches,
streams, roadways, etc. Consider possible future structures and equipment which could
interfere with clearances and accessibility.

When working near water or wetlands, additional permits may be required from various
agencies, including:
· Washington State Department of Fish and Wildlife
· Department of Ecology
· Corps of Engineers, and
· Department of Natural Resources
These permits may take a long time to acquire, so consideration should be given to avoiding
areas where these permits are required. Contact the Municipal & Land Planning group for
additional information and assistance.

Vaults
Do not place vaults in road intersection or 'crosswalks.
Use cast iron manhole covers or solid concrete covers on pulling
vaults in areas that are subject to normal roadway traffic. When
installed in a driven lane, the vault should be placed so the
covers fall between the wheel paths.
Vaults installed within a road shall include a six-inch ring riser
to accommodate potential grade changes.
Diamond plate lids and ventilated lids, evelll though they are
rated to H-20 loading, should not be used illl areas subjected to
normal roadway traffic. Shopping center parking lots, truck
bays, commercial/industrial driveways, etc., fall into this
category. The reasons for this are:
· The lids have a history of warping and breaking.
· The hold-down bolts tend to work loose, so the lids bang
loudly when cars drive over them.
· Gravel and debris tends to pack in and jam in the doors so
they will not open.
See Standard Practice 6775.0030, "Vault and Handhole Selection
and Application, " for additional informatioll.
When in parking lots, locate equipment in planter strips or in
landscaped areas when available to avoid huving cars parked
over the vault when the equipment needs to be operated or
maintained.'
An H-20 rated lid may be fitted with more durable "stealth"
doors that use 4 lock-down bolts. These doors are special order
material but may be appropriate where existing vaults are
difficult to relocate. Contact the Standards Department for
application and use.
Vaults installed on a road shoulder or sidewilllk shall include an
adjustable cover to accommodate potential grade changes.

Before Installing the Vault
Ensure the following tasks have been done before excavating for the vault:
· Contact local government agencies when required.
· Locate and mark underground utilities.
· Determine the vault's location and establish the site's finished grade.
· Identify and install required erosion and sediment control structures. Refer to Standard
0150.3200, "Techniques for Temporary Erosion and Sediment Control" and local
jurisdiction regulations.
Basic Vault excavation
Shoring Excavations over 4-feet deep shall be shored or sloped before any worker enters. Manhole
shoring boxes are available from rental companies.
On deep excavations where it is impractical to shore or slope, the vault hole can be
over-excavated by 8 to 10 inches and then raised to depth with crushed rock. The excavation
can then be leveled from above with a backhoe before the vault is set. A transit may aid in
establishing the correct grade.
Unstable Soli In areas such as river valleys where there is a high water table, several things can be done to
minimize construction problems due to soil caving into the excavation:
· If the problem is severe enough, the area around the excavation site can be dewatered
with well points and pumps before digging.
· A manhole shoring box can be rented.
· Sheet piling and jacks can be used for larger or deeper excavations.
Adjusting to Grade Vaults that are to be placed in landscaped areas, should be set a minimum of 2 inches above
finished grade.
Vaults and handholes to be set in pavement or sidewalk areas should have either an
adjustable top section or, if manholes are to be used, one or more 6-inch ring risers under the
cover section. This will allow accurate and easy adjustment of the top surface to finished
grade, and can prevent costly movement of the vault if the grade is lowered in the future.
Install the vault so that the top of the cover is about 2 to 3 inches lower than the pavement.
The adjustable lid can be leveled and adjusted up to 5 inches with the adjustment bolts. (See
Figure 2, Installing Adjustable Vault lids.)
The exception is electric secondary handholes, which are always set flush to final grade.

excavation
Procedure
Follow these steps to excavate for the vault.
1 Determine a suitable place to put the spoils, at least 2 feet from the edge of the
excavation and per l,ocal jurisdiction requirements. Consider sediment control
requirements.
2 Dig a hole large enough to accommodate the vault and allow for easy installation
and compaction.
3 Remove debris and level the bottom of the excavation.
4 Prepare the bottom of the excavation so that the vault will rest on solid undisturbed
earth with a 6-incb. base of crushed rock. This prevents vault settling and conduit or
pipe breakage.
Setting the Vault
Vault Storage
Set vaults and handholes using the vault manufacturer's delivery truck whenever possible. If
this is not possible or practical, store the vault on firm level ground. Vaults and lids are
subject to damage if stored on uneven temin.
uttlng
When lifting handholes 4'-8" X 7' or smaller, as a minimum use either 6-foot slings (MID
7487600) or a spreader bar. The inaeased angle aeated by using a sling any shorter than
6 feet may stress the vault walls to the point of collapse.
Flooded
excavations
Larger vaults will float if the excavation is flooded. Do not lower a vault into a flooded
excavation until as much water as possible has been removed. If an excavation is to be left
open in saturated soil where the water table is likely to rise and :fill in the hole, it is helpful to
allow water back into the vault to prevent the vault from floating to the surface. To protect
against flotation, aeate a small hole in the vault wall for water flow, using an available
knockout. Be sure to seal any holes with grout when work is complete.

8, CAUTION!
Many vaults larger than 4'-8" x 7' lack sidewall strength unless the lid or cover is in place. H
it is necessary to bacIdill without the cover in place, temporary support may be needed to
prevent the vault from collapsing.
H a vault is back:filled with wet material, or if large amounts of water are allowed to saturate
the bacldilI material before it can become compacted, the vault walls may collapse.
Backfill around vaults should consist of good compactible material such as clean earth fill,
crushed rock, f10wable fill, or sand No voids should remain between the vault waIls and the
sides of the excavation. Backfill progressively, and compact each lift thoroughly. The back:fill
material around vaults set on public rights-of-way shaII have a minimum 95% compaction.
Knockouts are provided in various locations. Any knockout section may be completely
removed without impairing the strength of the vault. Remove knockouts from the inside of
the vault. Do not remove any portion of a vault wall other than the knockouts.

Using and Installing Hlllholders
1&1I
Scope
This standard covers the use and installation of preformed fiber-reinforced plastic retaining
walls ("hillholders").
Environmental Requirements
Temporary erosion and sediment control requirements must be identified and appropriate
controls installed prior to beginning any excavation, trenching, or dewatering procedure.
Refer to Standard Practice 0150.3200, "Techniques for Temporary Erosion and Sediment
Control," and/or local jurisdiction requirements.
Purpose of Hlllholders
Whenever a cut is made into sloping terrain to allow for the placement of padmount or sub-
mersible equipment, the problem of dirt and rocks sloughing onto and around the back and
sides of the equipment is a concern.
1bis can cause:
· Damage to the equipment finish
· Corrosion
· Possible shifting of the equipment off the pad
· Restricted ventilation for padmount transformers
· Unsafe footing for operating personnel
Prefabricated hillholders provide protection for single transformers and other padmounted
equipment. A hillholder can be installed at the time equipment is installed or added to exist-
ing installations.

Purpose of Hlllholders, Continued
When to Use Use a hillholder for padmounted equipment when:
Hlllholders . A retaining wall 14- to 3D-inches high is needed.
· A slope is in excess of 1 foot rise for each 3 feet of horizontal distance.
NOTE: For retaining wall less than 14 inches, use railroad ties or other suitable'material.
Select the
Correct Size
The dimensions of the padmount or vault must be known so that a hillholder of the proper
size can be selected. The table below lists dimensions and typical applications for the various
sizes of hillholders.

Installation
Follow these steps to correctly install the hillholder.
1 Check the slope where the hillholder is to be installed and confirm that the
hillholder's height is adequate.
2 Excavate into the hiIIside and prepare a level area of sufficient size for the vault
and the hillholder. Do not disturb any more of the hiIIside than is necessary.
3 Prepare the excavation and install the vault. Refer to Standard Practice 6775.0040.
4 Backfill the excavation to within 4 inches of finished grade.
5 Level and tamp the soil around the edges of the vault. Refer to Figure 5.
NOTE: The inside opening of the hillholder should be slightly larger than the
vault. This allows the hillholder to be installed around the outside of the vault. The
vault will help to anchor the hillholder in place and prevent movement.
For an ExIsting
Installation
To add a hillholder to an existing installation, excavate a suitable area 4 inches deep around
the perimeter of the vault. Level and tamp the soil around the edges of the vault.

SIDE VIEW
If the hillholder must be set on top of a luger vault, drive two IS-inch machine bolts into the
ground at the back edge of the vault to prevent the hillholder from sliding forward. The bolts
should extend several inches above the top of the vault. Place the inside edge of the hillhold-
er against the bolts as illustrated.
Figure 5
Grade of bacldill
After the vault and the hillholder are set in their final positions, carefully bacldill around the
hillholder and compact the soil in 12-inch lifts to the level of the surrounding grade. The
grade on the bacldill at the rear of the hillholder will depend upon the condition of the
hillside. If the hillside is a lawn, then the slope of the hillside should match the slope of the
hillholder as closely as possible. If the hillside is of loose material or soil, make a small
depression or trench of approximately 2 or 3 inches behind the hillholder.

Customer-Supplled Trench Requirements limB
(--) Scope
This standard provides requirements for customer-constructed trenches, vault holes and road
crossings.
Customer Responsibilities
PSE's Electric Tariff 0, Schedule 85, requires customers:
Provide the trenching and excavation for Contract with Puget Sound Energy to
vaults and backfill in accordance with Puget provide this work at its estimated cost.
Sound Energy standards and work sketch.
See Standard Practice 6790.0050, "Customer's Acknowledgement of Responsibilities When
Providing Trenching," for authorization requirements on public rights-of-way and easements
on property other than the customer's.
Inspectloll/Coordlnatlon
Puget Sound Energy shall assign an inspector/coordinator to oversee the trenching,
equipment placementfmsta1lation, and backfilling.
· Work shall be subject to the inspection and approval of PSE.
· No work shall be backfilled, covered, or concealed until it has been inspected and
approved by the inspector.
)
Erosion Control
The customer is responsible for identifying the necessary temporary erosion and sediment
control requirements. These controls must be installed prior to beginning any excavation,
trenching, or dewatering procedure. Refer to Standard Practice 0150.3200, "Techniques for
Temporary Erosion and Sediment Control," and/or local jurisdiction requirements.
Trenching and Backfill
The trench shall meet the requirements of Standard Practices 6790.0130, "Trench
Dimensions and Facility Placement," and 6790.0140, "Trench Excavation and Backfill."
Exceptio,,: If PSE-provided DB-I20 conduit is installed in a customer-provided trench, the
conduit shall be bedded with three inches of sand and shaded with three inches of sand. This
is required due to the high frequency of damage to PSE facilities that otherwise occurs. This
requirement applies to both main line trenches and road crossings.
Sloping and
Shoring
Trenches or vault excavations which are 4-feet deep or greater shall be sloped according to
WAC 296-155 Part N, unless directed otherwise by PSE.
NOTE: Shoring is "ot allowed except when specifically approved by PSE.
Placement of
Spoils
Trench spoils shall be placed in a location that allows workers access to the trench and does
not block vehicles from passing alongside the trench to unreel cable or unload conduit.

1 Locate the vault according to PSE's work sketch.
2 Determine a suitable place to put the spoils which is at least 2 feet from the field
edge of the excavation.
3 Excavate so the vault is in correct alignment with the trench and so that conduits
can be brought straight into the vault.
4 Dig a hole large enough to accommodate the vault and allow for easy installation
and compaction, as shown in Figures 1 through 8 in Standard Practice 6775.0040,
"Vault and Handhole Installation."
5 Remove debris and level the bottom of the excavation.
6 Prepare the bottom of the excavation so that the vault will rest on solid,
undistuJbed earth with a 6-inch base of crushed rock. This prevents vault settling
and conduit breakage.
NOTE: Be certain that the vault will be level, square with adjacent structures, and
at the proper grade.
Vault Backfill
Materia.
The bacldill material around vaults should consist of compactible material such as clean
earth fill, crushed rock, flowable fill, or sand. No voids should remain between the vault
walls and the sides of the excavation.

Cables Under Directly buried cables shall not be installed under a structure that will restrict access for
Structures maintenance or replacement.
If no other route is available, 1/0 primary and secondary cables may be placed under a
structure if the following conditions are met:
· The cable is installed in conduit
· There are no low points in the conduit that could fill with sediment and prevent the
cable from being replaced in the future.
· The soil and the structure are both structurally sound and not susceptible to settling.
· The cable system will not be loaded to over half of their normal ampacity (because the
soil can dry out beneath structures, which will limit the ability of the soil to conduct
heat away from the cable).
· Adequate access is provided to each end of the conduit, including room for vaults, if
necessary.
· The cable does not pass within 5 ft of where a computer monitor will be used. This is
because the EMF from the power line can cause the image on the computer monitor to
be distorted or jittery.
Feeder cables shall not be installed under structures without approval of the Standards
department.

Wheel trenching is an approved construction method that requires a minimum cover of
12 inches of either conaete or controlled-density fill (COF). Refer to Standard Practice
6790.0150, "Wheel Trench Constroction, " for more information.
"Separation" is the minimum distance between the surfaces of two utilities, not the centerline
distance.
Conduits shall have a minimum separation of two inches in all directions from each other.
See Standard Practice 6800.6000, "PVC Conduit Installation," for additional information.
A minimum of 12 inches of radial separation shall be maintained when directly-buried
electric and gas utilities run parallel (NESC 353.A1 Deliberate Separation). Gas and power
circuits shall not be random laid with each other.
A minimum of 12 inches of vertical separation shall be maintained when directly-buried
electric and gas utilities aoss, except a minimum of 6 inches shall be maintained if the
electric cables are in a continuous (vault-ta-vault) section of conduit.
Conduit containing electric cables shall not enter the same manhole, handhole, or vault with
gas or other fuel lines (NESC 320.B.5).
)
A minimum of 12 inches of radial separation shall be maintained between the electric and
communications cables (NESC 353 Deliberate Separation).
Exception: This distance may be reduced if both parties agree (NESC 354D Random
Separation). If both parties agree, the separation may be reduced to 4 inches (a PSE
requirement).
Stacking communications conduits on top of power conduits is discouraged. If this must be
done, see Standard Practice 6790.0140, "Trench Excavation and Backfill," for special
backfill requirements around duct banks.
Generally, other utilities may share a trench with PSE's facilities, but this permission may be
denied if:
· In PSE's judgement, the installation, operation, or maintenance of either PSE or the
other utility will be hazardous, or
· The logistics of the installation are onerous.
· Direct access to PSE's facilities would be compromised.

The material used to fill the trench. If the trench is shaded
with select material, the bac1dill is the material that is
placed on top of the shading.
Select material that is placed in a level layer on the bottom
of the trench before the cable or conduit is installed. It
uniformly supports the cable or conduit off the trench
bottom so the cable or conduit is protected from rocks and
an uneven trench bottom.
Select material that is placed immediately on top of the
cable or conduit to protect the cable or conduit from being
aushed or damaged by the impact of coarse backfill
materials.

Locates
Notify the UndeIgl'Ound Locating Center (1-800-424-5555) of the excavation at least two
working days prior to any excavation (WAC 296-155-655).
Site Preparation
)
The party (pSE, developer, governmental entity or customer) that is doing the excavation
shall assure the excavated or loose material is placed at least two feet from the field edge of
the trench. Access to the trench shall be provided and standing water shall be removed from
the trench.
Integrity of Conduit
The party (pSE, developer, governmental entity or customer) that installs the conduit shall
assure the conduit is continuous, the inside is clean of dirt and debris, and the joints are
permanently glued together. The party that digs and ])JIl'lrfills the trench shall assure the
conduit is not broken, ovalled, or aushed when the trench is bac1dilled. In addition, the
proper positions of the facilities shall be maintained when the trench is bac1dilled.

IBmI
--) General Backfill Requirements
The requirements of this standard are designed to provide uniform support and physical
protection for the cable or conduit system. The intent of these requirements is to eliminate:
· Sharp objects or protrusions that will cut or penetrate the walls of the cable or conduit.
· Material that will create pressure points that will crush the cable or con~uit.
· Suspensions of the cable or conduit off the bottom of the trench that will cause the cable
or conduit to bend beyond its design limits or overstress the cable or conduit when the
trench is backfilled.
· Material that, when backfilled into the ditch, will damage the cable or conduit upon
impact.
· Material that will create a subterranean drain or surface erosion.
Backfill Material Restrictions
Backfill material shall not contain:
· Garbage, cans, glass, decomposable organic material, or construction debris.
· Roots or root balls larger than 10 inches (measured in their maximum direction).
· Washed gravels, including pea gravel.
· Material that will not compact.
.) Soli Classifications
The requirements of backfill depend on the composition of the native material. In some cases
the native material is adequate, and in others bedding and shading material is required. For
the purposes of this standard, three soil types are defined in Table 1.
Table 1
Soil types and definitions
Coarse, poorly-graded gravel
This material is comprised primarily of gravel with little
sand, finCSy silt or clay. When excavated the trench bottom
commonly contains loose rock of four inches in diameter or
larger.
This material is comprised of a mixture of gravel, sand,
fines and clay. It holds a vertical trench wall. The excavated
trench bottom can be saaped with the teeth of the backhoe
bucket to eliminate rocks larger than four inches in diameter
and leave behind a loose sand/clay/silt mixture that will
provide uniform support for cable and conduit.
This material is comprised primarily of sand, silt and clay. It
contains no rock larger than two inches in diameter.
The material primarily consists of decayed plant matter.

EIIB
In plam of the previous requirements for bedding, shading, and bac1dill, duct banks
comprised of more than one layer shall be bedded with sand, controlled density fill (COP), or
fluidized thermal backfill (FfB) and the conduits covered with three inches of the same
material.
In place of the requirements for duct banks, if four or more feeder conduits are installed in a
trench, fluidized thermal bacldill (FfB) shall be installed around the conduits to a depth of
six inches above the top conduit. See Standard Practice 6790.3050, "Using Fluidized
Thermal Bacldill," for additional information.
Most municipalities require 95% compaction of bacldill material used in road crossings. The
use of SIB-inch aushed rock is preferred for this application.
The party (pSE, developer, governmental entity or customer) that is doing the excavation is
responsible for compaction of the bacldill and any damage to the cable or conduit caused by
the compaction. All bacldill shall be consolidated according to the terms of the applicable
road use permits and right-of-way agreements. Most jurisdictions require a minimum. of 95
percent compaction. To obtain the required degree of compaction, the bacldill material may
be tamped in layelS or select material, such as SIB-in. minus, may be imported. Proper
compaction requires relatively dry material and a trench that is free from standing water.

Occupancy Permit
Issuance
Primary and secondary conductolS shall not be energized until adequate backfill is in plam to
provide physical protection for the cable system. Generally, this means the trench must be
backfilled to the depths required by Standard Practice 6790.0130, "Trench Dimensions and
Facility Placement," before a system may be energized.
Before the permanent occupancy permit is issued, conductolS for services may be energized
on a short-term basis if:
· If, in the judgment of PSE, the service will be safe, and
· A minimum of six inches of bacldill has been installed over the entire service length.
If the permanent occupancy permit has been issued, the service may not be energized without
complete bacldill.

Introduction
What Is Soli
Compaction?
Soli Compaction
-
This standard covers compaction techniques to meet requirements of city, county and state
codes when performing work that includes excavation and backfilling.
Soil compaction is the process of increasing the mean density of disturbed soil by applying
mechanical energy to drive out air voids and excess water. Proper compaction is desirable
because it:
· Eliminates settling
· Increases load carrying characteristics
· Improves soil stability
· Reduces water penetration and movement
· Decreases frost damage
Safety Requirements
Traffic comol must be considered as specified in Standard 0100.4000, "Traffic Control."
Factors that Affect Soli Compaction
Moisture Content Proper compaction depends on having the right moisture content in the soil. Just enough
water is needed to act as a lubricant between soil particles so that compaction energy will
move soil particles closer to each other and, in the process, expel air and water.
.)
Ufts
The thickness of the soil being worked at one time (called the lift) is also important to good
compaction. The thinner the lift, the better the compaction. Saving time by working in thick
lifts will result in poor compaction.
Clay soil, especially, requires small lifts. Clay tends to laminate when lifts are too thick,
because water can work between the lifts making it impossible for the layers to bind tightly
together.
The maximum size of the lift is also related to the type of tamping equipment being used (see
the Road Crossings and Underground Installations section of this standard).
Soli Classifications
Sand Slit (Granular) Sand silt consists of small mineraI grains which may be coarse or fine, but always granular. If
you squeeze dry sand silt in your hand, it will fall apart when pressure is released. If you
squeeze moist sand silt, it will retain its shape when pressure is released.
Sandy Loam and
Slit Loam
(Cohesive)
Sandy or silt loam is a mixture of fine sand and clay. It is lumpy when dry, but can be
pulverized easily. Sandy loam and silt loam have a soft fluffy feel. When wet, these loams
run together in puddles. Moist casts can be handled without breaking, which indicates that
they Can be compacted effectively.

Clay (Cohesive)
Soli Compaction
-
Oay is made up of the finest particle size of any soil. Particles are scale-like and slide on one
another. Thus, there is little friction between particles. With the proper equipment, clay can
be readily compacted. It is naturally plastic and cohesive.

Using Fluidized Thermal Backfill (FTB)
--
(') Scope
1bis standard covers the use and application of fluidized thermal backfill (FIB) for electrical
conduit backfill. '
What Is FTB and Where Is It Used?
FfB is a simple conaete mixture that is designed to conduct heat. Its is poured around
cables and conduit to conduct heat away from them. This allows the cables to carry more
current without overheating.
FfB is primarily used in baclrfi11ing trenches where a high value of cable ampacity is
required. It may also be used as backfill where 100 percent compaction is required, where
physical protection of the cable or conduit is needed, or where adequate backfill material is
unavailable.
& CAUTION'
Selection of FTB Material
FfB material is available in the following two variations:
)
· Trenches over 12-in. deep.
· Where no additional strength
component is needed over that
of normal backfill (300 psi
max).
· Backfill of trenches 12-in. deep
or less (i.e., cable replacement.
within roadways).
· Around structures where added
strength is desired (up to
1000 psi).
NOTE: Both products can be ordered with a red tint, if required by the municipality.

Prior to bac1cfilling a trench with FfB the following conditions must be met:
· Trenching activities and conduit installation should be done in accordance with PSE
Standard Practices 6790.0075, "Customer-Supplied Trench Requirements," 6790.0130,
"Trench Dimensions and Facility Placement," 6790.0140, "Trench Excava~9n and
Backfill," and 6800.6000, "PVC Conduit Installation."
· Steps must be taken to prevent the conduit banks from "floating" when the FI'B is
introduced to the trench, see Figure 1.

) Placing the FTB
Follow these instructions for placing the FfB:
1 Pour into the trench and completely fill all voids without causing excessive
segregation. Maximum pour height shall be 4 feet.
NOTE: Do not Wbrate or compact the mixture.
2 To reach inaccessible locations, the mixture may be pumped through conventional
concrete pumps.
3 The flow rate can be adjusted slightly by adding water at the site (as long as no
segregation occurs, and the FfB fills all the voids completely when poured).
)
Conducting 8 Thermal Probe Test
Collecting Samples If directed by the project manager, a sample of the FfB should be collected, at a minimum,
every pour date. For larger backfill operations, a sample should be collected every fourth
mix truck to ensure consistency of the product. Each sample should be labeled appropriately
with the following:
· Date
· TlID.e
· Mix truck identification number
· Location of pour
· Name of person collecting the sample
Samples shall be cast in 3-inch by 6-inch cardboard or plastic molds, held in a moist
environment, and not disturbed until the FfB has hardened. Follow ASTM Standards C172
and C31 for the sampling, curing, and testing of concrete, except use cardboard or plastic
sampling molds to facilitate stripping.
Thermal Resistivity When hardened, the FfB should have a thermal resistivity of less than 40oCcm/W when
moist and less than l00oC-an/W when totally dry.

Safety
· Keep solvent cements for PVC pipe away from all sources of ignition. Maintain
ventilation to minimi7.e breathing of solvent vapors and to reduce fire hazard. When PVC
glue is used in vaults, constant ventilation shall be maintained or workers shall wear
respiratory protection. Avoid contact with skin and eyes. Do not smoke, eat, or drink while
handling solvents.
· Excavations shall be properly shored or sloped before work in the trench begins.
Precautions such as air testing and forced ventilation may also be necessary.
Before Work Begins
· A tailgate conference shall be held, and potential hazards discussed with all workers.
· Underground utilities shall be located and marked.
· Detailed planning is essential. Plan ahead whenever possible, including a careful
inspection of the job site. Determine special equipment needs before bringing a crew onto
the site.

Conduit Types and Sizes
Puget Sound Energy's standard conduit is grey PVC DB-l20 or Schedule 80 sizes 2", 3",
4", or 6" as in Specification 1025.6310.
Conduit provided by the customer that is to be owned and maintained by Puget Sound
Energy shall be grey PVC electrical grade DB-I20, Schedule 40 or Schedule 80. .conduit
sizes shall be 2" , 3" , 4" , or 6" . Conduit shall meet ASTM F512 requirements for DB-I20
and NEMA TC-2 requirements for Schedule 40 or 80.
)
Trench Preparation
Consider these points when constructing the trench
· Construct the trench so that the bottom provides a firm, stable, and uniform support for
the full length of the conduit. Oear the bottom of rocks and any debris which could
damage the conduit.
· If other utilities obstruct the way, slope or drift the trench to avoid the obstacle, to
minimi7,c the use of conduit bends which will inaease cable pulling tension.
· Trench depth will vary depending on duct bank formation, final grade, earth cover
requirements, and local regulations. See Standard Practice 6790.0130, "Trench
Dimensions and Facility Placement," for additional requirements on trench dimensions.
· Pay particular attention to elevation changes in the trench bottom. Numerous changes in
elevation, even if gradual, add bends to the conduit run which will substantially inaease )
cable pulling tension. . "
· Level the trench so that there are no low spots which will trap water and silt in the
conduit system.
Conduit Placement
Separation The separation between two, three, and four-inch conduits or a four-inch and a six-inch
Requirements conduit shall be a minimum of 1-1/2 inches.
The separation between six-inch conduits shall be a minimum of two inches. Feeders require
greater spacing to help dissipate heat to maintain their ampacity ratings.
See Standard Practice 6790.0130, "Trench Dimensions and Facility Placement," for
requirements on separation between various utilities and between the power cables and the
customer's facilities.
Provide adequate support on each side of conduit when conduit crosses over another utility,
to prevent load transference onto other utilities.

Cable Pulling Tension
Conduit systems are designed for maximum cable pulling tension ca1aa1ations. Add
manufactured bends to the system only if they are absolutely necessary. Any deviation from
the original design shall be discussed with the engineer to ensure that the change will not
render the system unusable.
Keep the Bends
Down
Bends
" Sidewall
Pressure Exceeds
1000 Pounds
PVC Cement
Placement of conduit can also significantly affect pulling tension. Undulations from snaking
a conduit may look minor, but can result in hundreds of degrees of bend per thousand feet of
pull. Pulling tensions in straight conduit runs add up in a linear fashion, but bends in the
conduit cause the cable tension to be multiplied, greatly increasing the stress on the cable.
This can increase cable pulling tension beyond acceptable limits.
Lay conduit as straight and level as possible, to ensure that a usable system is installed.
The radius of any bend should be as large as possible to aid in cable pulling. Large sweeping
bends can be formed by assembling several conduit sections, allowing approximately
30 minutes for the joints to cure, and then bending them into the trench. The conduit run
should be firmly staked for the desired radius, to ensure that the joint is not disturbed or
damaged before or during bac1dill. Keep bends at least three feet outside the vault to allow
for operation of the radder.
The maximum amount of bend at joints should be limited to 5 degrees to prevent damage to
conduit fittings and cable during pulling. Mark on the work sketch all bends that are added to
the conduit run, including their degree, radius, and location.
)
Keep the number of 90 degree bends in a primary conduit run to a minimum. When
ca1aa1ations show that the sidewall pressure at a 45 or 90 degree elbow exceeds 1000 pounds,
encase the conduit bends in concrete to prevent burn-through.
Use all-weather grade PVC solvent cement on all PVC conduit, following manufacturer's
recommendations. Do not use PVC cement that appears lumpy or stringy, exhibits excessive
thickening, or will not stir to a smooth consistency.
Reclose all containers tightly to prevent solvent evaporation.

Conduit Assembly Procedure
Follow these steps to assemble the conduit.
1 If conduit needs to be cut, make a square cut with a fine tooth saw (diagonal cuts
reduce bonding). Bevel the outside edge with a knife and abrasive cloth to remove
burrs and raised edges for easier installation.
2 Wipe all dirt, mud, and shavings from conduit and fittings before joining. Conduit
surfaces must be clean and dry so cement will adequately adhere. Use the small
dauber on 2-inch and 3-inch conduit; use the roller on 4-inch and 6-inch conduit.
3 Apply a hoeral and uniform coat of PVC cement to the conduit and bell end,
coating both surfaces to the full depth for ease of assembly. Assembly must be
done while the surfaces are still wet and fluid.
4 Slip the conduit straight into the fitting with a slight twist until it bottoms. Hold
the joint for 15 seconds so the conduit won't push out. If it is necessary to drive
two conduits together, use a board to protect the conduit edge.
5 Let the joined sections cure undisturbed for at least five minutes before handling. If
the conduit is to be bent in the trench, let the joints cure completely before
bending, approximately 30 minutes.
6 Plug all exposed conduit ends during breab in work to keep dirt, mud, and water
out of the conduit.
7 Bevel the inside edge of Schedule 80 when joining it to DB-I20 conduit.

Installing Conduit Into a Concrete Vault
')
Conduits shall be plumbed into vaults so all
cables can be freely switched and parked
without restriction from other cables.
Whenever possible conduits shall enter
vaults so all of the cables coil in the same
direction (either clockwise or
counterclockwise). Conduits shall not enter
vaults at 90 degrees to each other at the
same comer unless they are positioned so
they freely aoss each other and do not
interfere with the installation of the present
or future cables.
In vaults that contain feeder cable:
· If the cables will be spliced together (as
opposed to using hammerheads), plumb
the conduit so one set of cables coils
clockwise and the second set coils
counterclockwise.
· In vaults that contain feeder cable, it is
preferred that the conduits enter the short
ends of the vault. This provides more
room for rigging pulling equipment.
In vaults that do not contain feeder cables,
the conduit may enter either the short of the
long side of the vault.
Duct banks that are four or more conduits
wide should be reconfigured as they enter
the vault so they are no more than three
conduits wide.
If the trench line is offset, begin angling the
conduit toward the vault about 20 feet away.
Avoid using 90 degree bends to bring
conduit into the side of a vault.
NOTE: Do"ot use Schedule 80 for the first
section of conduit out of the vault. It will
not fit the rodder adapter.

1 Place comptICUd soil in the trench up to the knockouts. This will help to prevent
shearing or "egg shaping" of the conduit where it enters the vault. .'
2 Push the conduits through the knockouts or "termaduct" reo~ptac1es at the end of
the vault, making sure they enter straight and level, perpendicular to the vault wall.
3 Cut the ends off 1 to 2 inches inside the vault, keeping the oonduit approximately
2 inches apart to allow for placement of cable pulling equipment.
4 Glue the bell ends onto the conduit.
5 Grout around the conduits and bell ends to prevent dirt and water from entering the
vault. This will also keep the soil from settling around the outside of the vault. Seal
all empty ducts with expandable duct plugs. Use duct foam to seal around cables in
the duct to prevent water migration into vault. Refer to Standard Practice
6800.6500, "Application of Conduit Plugs and Seals."
NOTE: Vaults fitted with "termaducts" do not require grouting.

~ :-~ I: : , f .
1 Pump any standing water out of the trench.
2 Check conduit spacing. Conduits must be approximately 1-1/2 to 2 inches apart
and at least 1-1/2 to 2 inches from the trench walls, so that the rn:lCkfill can flow
around the conduit and provide equal support for the duct on alllddes. (Proper
spacing will also inaease the cunent carrying capacity of the collductors.)
3 Add backfill gradually to the sides of the conduit bank first. This will act as a
vertical and lateral support and protect the pipe from deflection.

Installation of Electronic Markers
---
r) Scope
1bis standard covers installation methods for electronic underground location markers.
Why Markers are Used
Electronic underground location markers are used to mark any facility that cannot be located
with other locating equipment. They are the most dependable way to mark conduit stubs, bu-
ried splices, stubouts, etc.
Markers removed from temporary installations such as crossings or cuble loops should be
returned to Stores for reissue.
types of Marker. 1\vo electronic markers are available:
· 4 in. ball (MID 7668501)
· 15 in. flat (MID 7668500)
The ball marker has the advantage of being self-leveling and easier to place, which mini-
mizes future locating problems.
Locating
Both markers can be located using the electronic marker locator, MID 6546505. The markers
are color coded, and tuned to a specific frequency for each utility.
)
Installation Requirements
Install the marker at least 6 in. above or to the side of metallic objects, such as cables or steel
handhole lids. These objects will absorb some of its signal and significantly reduce the
strength of the signal received by the locator. Never put the marker UIIder a metallic object.
The signal will be totally absorbed by the metal.
Place the marker about 6 in. above the item it is marking whenever possible. This will pro-
vide a cushion of soil, and allow flat markers to act as a digging shield when excavating with
a backhoe.

easy locating. (The maximum signal
range is 8 ft.)
2 Install the marker flat and level.
NOTE: Markers installed at an angle,
or that are bent or damaged during

C^') Scope
This standard provides minimum guideUnes for temporary erosion and sediment control
procedures for typical Puget Sound Energy (pSE) maintenance, installation, and emergency
repair activities. SiU-specijic erosion control plans alUllor loctJl ju"isdiction requirements
supercede this stIlndtJrd.
Introduction
Erosion and sediment control requirements are established by state alld local jurisdictions.
The intent of this standard is to ensure that minimum jurisdictional rc~uirements are met for
all PSE work.
In general, storm water run-off or pump discharge leaving a work site, shall be free of
sediment, and sediment shall not remain on any hard surface when the work is complete.
Any flowing ditch, body of water, or sensitive area shall be protected from erosion or
sedimentation caused by PSE work activities.

Vault dewatering with a sediment bag.
NOTE: This method is lIot approved for trench or excavation dewatering.
This illustrates a typical sediment bag installation discharging to a paved area w.ith catch
basins. The same method can be used in vegetated areas where less than 100 ft of vegetated
ditch or vegetated land is between the discharge hose and the nearest flowing ditch or body of
water.

~ure
)
Follow these steps to control runoff from excavated work sites including utility pole hole
excavations and bore pits.
NOTE: These techniques are minimum guidelines for erosion and sediment control.
Additional site-specific steps and practices may be required by the local jurisdiction and/or
by permit.
Terms that appear in italics are defined in the Definitions section.
& CAUTION!
Provide appropriate traffic control according to Standard Practice 0100.4000,
wrratIic Control." Install required shoring according to SWlldard Practice
0100.3100, "Excavation and Shoring Requirements."
2 After gas or electric emergency control has been achieved, install erosion and
sediment control measures as required before proceeding wiith repairs or
construction.
3 Evaluate the site for erosion control.
-OR-
Install erosion control measures indicated on the work sketch and/or required
by permit.
4 Prepare the site for precipitation and water runoff.
Use a sediment barrier to protect the entire downgrade portion of the site
including barriers for any flowing ditch or body of water.
If...
Then . . .
There is a possibility of rain
before the project is complete,
-OR-
If work is progressing during
the wet season,
· Use gravel bags to divert runoff
from a paved work site to
sediment control strll1ctures.
Install CQtch basin inserts and
gravel bags on affected
downstream storm iJllets
(Figure 4).
· Insert a gravel checA: dam or silt
fence barrier in open, dry
drainage ditches to reduce water
runoff velocity, prevent errosion,
and trap sediment (Figure 5).
· For utility pole excantions,
place gravel bags in a
semi-circle downgrade of the
excavation (Figure 7).

Then...
There is a flowing ditch or
body afwater adjacent to or
downstream of the intended
excavation,
Install gravel bags and silt fence
barrier between the flowing ditch
or body of water and the intended
excavation (Figures 6 and 8).
Contact the local jurisdiction for
guidelines to follow for erosion
and sediment control.
There is a flowing ditch or
body of water running
through the intended
excavation,
5 Remove obstructions:
· Store sod, beauty bark, landscape plantings, and other obstructions in a
separate area for replacement after construction as necessary.
· Place landscape materials on a tarp or plastic sheeting if storing for two
days or less. Otherwise, place plant material directly on the Dlltive ground
and cover roots with generous amountS of topsoil.
6 Prepare the spoils storage area, if needed and if allowed by the local
jurisdiction:
· If the spoils are to be placed on a paved or landscaped surface, place a tarp
over the entire area where excavated materials ~ to be stored.
· Place excavated material upgrade from the trench or excavation where
practical.

option allowed by some
jurisdictions).
Place the spoils on top of the tarp.
Cover the spoils pile with plastic
sheeting; secure the edges with
sand bags or gravel bags.
Place the spoils directly into haul

Protect adjacent body of water,
flowing ditch, or ditch line with
gravel bags and silt fe/ace. Spread
spoils within the protel:::ted area, if
allowed, and cover with mulch.

10 Backfill the excavation with native soil or select material, as rec:(uired. Be
careful not to damage the tarp protecting the native surface. lift the tarp to
slide residual debris into the excavation, ensuring that material iis not left on
the native surface. If this is not 100% successful, immediately broom off h~
surfaces or rake/shovel soft surfaces. Sediment shall not remain on hard
surfaces at completion of work.
11 Restore disturbed areas including vegetation or landscaping.
· Rake topsoil to a depth of 2-4 in. (if gravel or other inorganic: material was
used for backfill, place 2-4 in. of imported topsoil). Rake at ~l right angles
to the slope.
· For landscaped areas, replace previously stored landscape mnterials.
· For non-landscaped vegemted areas, hand-seed with erosi011l control seed
mix meeting the requirements of the local jurisdiction. Seed shall be
applied at a minimum rate of 1I2lb per 100 ft2.
· Place mulch on seeded or disturbed areas at a minimum depth of 2 in. or a
spread rate of 5 straw bales per 1000 ft2. Straw shall be sterilized to prevent
seed contamination.
12 Remove erosion control measures after the work site is vegetated or otherwise
permanently stabilized. Dispose of collected sediment and used erosion
control materials appropriately as construction debris. For excavation sites in .)
unpaved areas, some erosion control measures may need to be lIlaintained and
remain in place for several months until vegetation is stable.
