PMG Phase 1 Interim Action
I. PROJECT BACKGROUND
The Boeing Commercial Airplanes (BCA) plant in Everett, Washington is used for the
manufacture of 747, 767, 777, and 787 aircraft. Primary construction began in 1968
and was completed in 1969. Additional building and facilities have been constructed
since then. The head of Powder Mill Gulch (PMG) is located on the northern end of the
Everett Plant property.
Tricholoroethylene (TCE) was first detected in PMG groundwater in March 2003 with
the installation and sampling of monitoring well EGW075. A phased remedial
investigation has been conducted to characterize the nature and extent of the
groundwater plume and discharge of contaminated groundwater to surface water in
Powder Mill Creek.
Based on initial site characterization activities, the TCE source area was identified as an
approximately 14,000 square foot (ft2) area centered below the deepest portion of a
detention basin at the head of PMG. TCE concentrations in the source area were
historically measured as high as 31,000 micrograms per liter (μg/L). An interim action
(IA) was completed in 2008 within the source area using in situ electrical resistance
heating (ERH) to reduce TCE concentrations in the source area. The objective of the
source area IA was to reduce concentrations of TCE in groundwater to below an
established remediation level of 500 μg/L. The objective was achieved through most,
but not all of the source area through the ERH application. More recent application of
contingent and focused bioremediation appears to have successfully achieved the IA
objective throughout the source area.
The TCE groundwater plume in PMG extends north-northeast from the stormwater
detention basin. A portion of the plume discharges to Powder Mill Creek approximately
500 ft north of the detention basin where Powder Mill Creek becomes a perennial
gaining stream. The plume continues northward beneath Seaway Boulevard (which
bounds the northern edge of Boeing property); onto City of Everett Lot 9, Intermec, and
CRISTA Ministries properties; and, ultimately, discharges to Powder Mill Creek at the
toe of the plume, beginning approximately 1,000 ft north-northeast of Seaway
Boulevard. The plume, defined by TCE concentrations in groundwater greater than the
project screening level of 0.49 μg/L, is approximately 2,850 ft in length. TCE has been
measured in groundwater at concentrations as high as 2,000 μg/L at wells near Seaway
Boulevard, and 1,900 μg/L north of Seaway Boulevard.
The plume is present primarily in the upper portion of the Esperance Sand Aquifer, at
depths of 4 to 75 ft below ground surface (BGS). A 4-ft-thick silt layer within the
Esperance Sand Aquifer is relatively continuous over the length of the plume and
serves as a barrier to deeper vertical migration of TCE in the source zone and over
most of the downgradient dissolved-phase plume. A relatively impermeable Lawton
Clay unit is present approximately 30 ft below the silt.
Sampling in Powder Mill Creek and from seeps on the banks and hillsides above the
creek have identified concentrations of TCE in Powder Mill Creek up to 38 µg/L (south
of Seaway Boulevard) and in seeps up to 530 µg/L (near the toe of the plume).
Statement of Work
I-2
PMG Phase 1 Interim Action
Boeing has agreed to perform a downgradient plume IA to address various elements of
contamination in groundwater and surface water. This IA is being performed under the
authority and conditions of Amendment No. 5 to Agreed Order No. DE96HS-N274
(Order; Exhibit A1 in Attachment 1 – Project Plans) between The Boeing Company and
the Washington State Department of Ecology (Ecology). The downgradient plume IA
will include two phases of work: the first on Boeing property, referred to as the “PMG
Downgradient Plume Phase 1 IA” (Phase 1 IA); and the second off Boeing property
referred to as the “PMG Downgradient Plume Phase 2 IA” (Phase 2 IA).
This SOW pertains solely to the Phase 1 IA being conducted on Boeing property. This
Phase 1 IA is being conducted to prevent further migration of TCE off of Boeing
property and reduce discharge of TCE into Powder Mill Creek through construction and
operation of a groundwater extraction and treatment (GET) system. The GET system
involves pumping groundwater from extraction wells to create a capture zone to control
the migration of TCE-contaminated groundwater, treating the groundwater through air
stripping of aqueous-phase volatile organic compounds (VOCs), and discharging
treated groundwater to the city of Everett (City) sanitary sewer system. Vapor-phase
TCE discharged from the air stripper will be treated through granular activated carbon
(GAC).

Sustainable Remediation Practices
The Boeing Company is committed to identifying cleanup project opportunities to use
natural resources and energy efficiently, reduce negative impacts to the environment,
minimize or eliminate pollution at its source, reduce waste to the greatest extent
possible and stay abreast of policy, technology and industry standards associated with
sustainable practices. This concept of sustainable remediation (SR) can be defined as
a remedy or combination of remedies whose net benefit on human health and the
environment is maximized through the judicious use of limited resources. SR
incorporates sustainable environmental practices into remediation of contaminated sites
to increase the environmental, economic and social benefits of a cleanup.
This
commitment includes using the contracting process to select suppliers who share
Boeing’s commitment to SR principles so that remediation work can be performed in a
way that reduces adverse impacts to the environment.
The following summarizes SR principles that the Contractor shall consider and
incorporate as reasonably feasible and applicable during performance of the SOW
described herein. Where appropriate, these principals are incorporated into the design
plans and technical specifications.
Summary of SR Principles and Objectives
Contractor will consider the “triple bottom line” for performance of this SOW, including
incorporation of efficient, low-impact work practices, procedures, and operations; and
use of sustainable materials and products. It is the goal of Boeing’s sustainable
remediation program to implement the following objectives in each project to the
greatest extent possible:
Environmental - Consider environmental effects of remedy implementation and
incorporate options to minimize the environmental footprints of a cleanup and conserve
natural resources.
Economic - Integrate sustainable practices throughout a remediation project’s life cycle,
evaluate return on investment.
Social - Partner with Boeing business units, regulatory agencies, the public and other
stakeholders to identify environmental, land use, health and safety aspects, and
economic goals in all phases of remediation projects to develop sustainable remedial
alternatives and select final remedies.
Core Elements
Sustainable practices emphasize the need to more closely evaluate core elements of a
cleanup project; compare the site-specific value of conservation benefits gained by
different SR strategies; and weigh the environmental trade-offs of potential strategies.
Sustainable Remediation addresses five core elements:
Energy – Promote efficiency and renewable sources.
Statement of Work

PMG Phase 1 Interim Action
D.
The Contractor shall locate in the field and either stake or lay out actual
plants at proposed planting locations prior to planting. Plants shall be
placed in a random, natural pattern following placement notes provided in
the Plans. On-center (O.C.) spacing called out on the plant schedule
indicates an average spacing dimension. For example, if the plan calls for
24 inches O.C., spacing shall vary from 18 to 30 inches O.C., with an
average spacing of 24 inches. Biologist shall approve proposed plant
locations and layout prior to installation by the Contractor. Any substantial
variations from the planting plan will require prior approval by the Biologist.
E.
Trees shall be handled by the rootball, not by the trunk. Plants shall be
installed upright, rotating them to give the best placement to adjacent
plants and topography. Hold plant rigidly in position until topsoil has been
backfilled and tamped firmly around the ball or roots.
F.
When the planting pit is backfilled halfway, place the specified quantity of
fertilizer and stakes, if necessary, as shown on the Drawings and these
Specifications. Evenly space the fertilizer around the perimeter of and
immediately adjacent to the root system. Carefully place water and
compact planting backfill, filling all voids. Do not injure the root system.
G.
When the planting pit is three-quarters (3/4) backfilled, fill with water and
allow it to soak away. Fill pits with additional topsoil and continue
backfilling. Ground bark shall be placed over all tree-planting saucers to a
compact depth of 3 inches. Water trees immediately after planting.
H.
Detailed directions for planting are described as follows (also refer to the
Drawings):
1. Container Trees and Shrubs: The following directions, adapted from
the International Society of Arboriculture, must be followed for
container plantings (see Details on Sheet C-8):
a) Dig a shallow, broad planting hole. Make the hole three times the
diameter of the root ball but only as deep as the root ball.
b) Stockpile excavated soil next to planting pit. The excavated soil will
be used for backfill in the planting pit.
c) Identify the trunk flare. The trunk flare is where the roots spread at
the base of the plant. This point shall be partially visible after the
plant has been installed. If the trunk flare is not partially visible,
some soil shall be removed from the top of the root ball.
d) Place the tree or shrub at the proper height. Before placing the tree
or shrub in the hole, check to see that the hole has been dug to the
proper depth and no deeper. It is better to plant the tree or shrub a
little high, 2 to 3 inches above the base of the trunk flare, than to
plant it at or below the original growing level. This planting level will
allow for some settling. To avoid damage when setting the tree or
Planting

shrub in the hole, always lift the tree or shrub by the root ball and
never by the trunk.
e) Straighten the tree or shrub in the hole. Before beginning
backfilling, view the tree or shrub from several directions to confirm
that the tree or shrub is straight.
f) Fill the hole gently but firmly. Fill the hole about one-half (½) full
and water settle the soil around the base of the root ball.
g) Apply fertilizer into planting pit as specified in Section 2.04.
h) Fill the remainder of the hole, taking care to firmly pack soil to
eliminate air pockets that may cause roots to dry out. To avoid this
problem, add the soil a few inches at a time and settle with water.
Continue this process until the hole is filled and the tree or shrub is
firmly planted.
i) Do not stake trees or shrubs unless necessary to keep the tree or
shrub straight.
a)
2. If bare root stock is to be used in lieu of container plants, all methods
for installation of container plants apply with exception of storage and
handling of bare root stock, which shall be submitted by Contractor
upon request for using bare root stock.

SYSTEMS - GENERAL
A.
This project comprises a groundwater extraction, treatment, and discharge
system for Powder Mill Gulch at the Boeing Everett Plant as shown in the
Drawings. The groundwater extraction system consists of 3 groundwater
extraction wells that are outfitted with submersible pumps that will convey
groundwater through a series of interconnecting pipelines to a treatment
system. The treatment system features a low-profile air stripper as the
fundamental treatment process. Subsystem processes for treatment of
groundwater include a discharge pump, temporary holding tank, and
transfer pump for testing, temporary storage, and/or retreatment of
groundwater; a moisture separator, duct heater, and GAC vapor treatment
vessels for the air stream from the air stripper; and other ancillary
subsystems. The system will be monitored and controlled by a PLC and
associated controls with remote telemetry and communications.
B.
Intent of the Drawings and this section is to provide ICM system
subcontractor a generalized schematic and functional description of how
the ICMs are to operate and provide the basis for developing a logic
ladder for PLC programming.

SYSTEM DESCRIPTIONS
A.
General – The following paragraphs describe functional requirements of
ICM systems and processes to which they apply. Automatic control of
process systems shall be accomplished through use of a PLC and
associated controllers. Remote communications to the Operator (i.e.,
automated signals and alarms to a remote Operator terminal and pager)
shall be controlled and performed by the PLC. Operator shall have ability
to remotely access the PLC and control certain extraction system and
treatment system operations (i.e., extraction pump operation and motor
speed, blower operation and motor speed, discharge pump operation and
motor speed, duct heater temperature control, and total system startup
and shutdown).
B.
Groundwater Extraction
1. The theory of the operation and control system for each respective
extraction system is identical.
a. Groundwater shall be pumped from each extraction well by a
submersible pump (e.g., P-101) and conveyed to the groundwater
treatment system through a series of interconnected pipelines.
Quantity of groundwater pumped from each well shall be metered
through a magnetic flow meter (e.g., FI/FIT-101). Flow rate shall be
indicated locally and transmitted to the PLC (PLC-501) located at
the treatment building. Combine flow rate of all wells will also be
metered through a magnetic flow meter (FI/FIT-201) at the influent
to the air stripper, indicated locally, and transmitted to the PLC.
PLC will display flow and totalized flow from each well individually
and sum the combined flow rates and flow totals from each
extraction well. Groundwater level in each well shall be monitored
by a pressure transducer (e.g., LE/LIT-101). Groundwater level
shall be transmitted to the PLC and displayed. Pump discharge
pressure shall be measured by pressure meters (e.g., PI/PIT-101)
at the wellhead, indicated locally, and transmitted to the PLC. PLC
will display pump discharge pressure at each well. Pump running
time shall be indicated in total cumulative hours at the PLC.
b. PLC shall monitor groundwater elevation via pressure transducers
in each well (LE/LIT-101, -102, and -103) and control groundwater
elevation at each well by signaling each well control panel (e.g.,
CP-101) located in a CP enclosure proximate to the well (or in the
treatment system building for EGW183) to adjust the groundwater
extraction rate from each respective well, by modulating the input
signal to the variable frequency drive (VFD) and thereby increasing
or decreasing the pump speed, to maintain a predetermined
groundwater elevation within the extraction well. If groundwater
level should fall below preset minimum level and pump speed has
been reduced to preset minimum speed, the PLC shall signal pump

Statement of Work
V - 130
PMG Phase 1 Interim Action
shut down after operator adjustable but preset time period. Pump
shall remain shut down until groundwater level returns to preset but
operator adjustable level above preset minimum level.
c. PLC will monitor pump discharge pressure at each well (PI/PIT101, -102, and -103) and send signal to respective CP. Set points
for low or high pressure conditions shall be established at PLC and
interlocked with CP and operation of pump. Low and high pressure
failure signals shall be indicated at PLC, if pressure is below low
pressure set point or above high pressure set point. PLC will signal
pump shutdown if condition persists after preset but operator
adjustable time delay. If pump shutdown is initiated, PLC will
remotely communicate condition to Operator.
d. The combined flow rate of all wells will be metered through a
magnetic flow meter (FI/FIT-201) at the influent to the air stripper,
indicated locally, and transmitted to the PLC. PLC will display and
totalize flow from each well and sum the combined flow rates from
the three extraction wells (total of FI/FIT-101, -102, and -103). PLC
shall compare the sum of the flow rates from each individual well to
the combined flow rate measured at air stripper influent. If flow
rates are not equivalent within a specified tolerance (e.g., if
summed flow rate is greater than 5% [plus the rated accuracy of
instruments] higher than the combined flow rate at treatment
building), a leak in the conveyance line may be present. Pipeline
failure (leak) signals shall be indicated at the PLC and remotely
communicated to Operator. If condition persists after an operator
adjustable but preset time delay, the PLC will signal initiation of
system shutdown sequence of the extraction system and treatment
system. If shutdown sequence is initiated, PLC will remotely
communicate condition to Operator.
e. Submersible pump operation shall be identified on a stack light
located at the respective well CP enclosure by illumination of a
green operating light (e.g., OL-101). Motor overload or other
system failures shall be indicated on a red stack light at well control
CP enclosure and a main control panel (CP-501) cover by
illumination of a red general alarm light (GA). Alarm lights and
displays shall remain illuminated or activated until failure is cleared
through the PLC user interface (remote or local).
C.
Air Stripper Treatment Equipment
1. The theory of the operation and control system for the air stripper
treatment system is described below.
a. The air stripping treatment equipment specified shall treat influent
groundwater over a range of flow rates. Air shall be drawn through
the low-profile air stripper from the suction side of the positive
System Operation Description
Section 17700
Statement of Work
V - 131
PMG Phase 1 Interim Action
displacement blower. The blower motor speed will be controlled
through a VFD. The blower is designed to maintain a constant but
operator adjustable air to water ratio. As influent groundwater flow
rate increases or decreases as measured by FI/FIT-201, PLC shall
signal CP-501 to proportionally increase or decrease air flow rate
supplied to the stripper, as measured by the air flow meter on the
stripper air intake (FI/FIT-301) to maintain a minimum air to water
ration of 60:1, by adjusting the blower motor speed through the
VFD. Air flow rate supplied to the stripper shall be supplied at a
minimum rate of 1800 SCFM and a maximum rate of 3600 SCFM.
b. The total groundwater flow rate entering the air stripper, as
measured by FI/FIT-201, shall also be monitored by the PLC
against a total allowable flow rate into the air stripper (i.e., the
maximum design [or empirically demonstrated] groundwater flow
rate at which the air stripper can achieve contaminant reductions to
less than the regulatory discharge limit). Groundwater flow rates in
excess of this value shall signal a system alarm and be remotely
communicated to Operator. If condition persists after an operator
adjustable but preset time delay, the PLC will signal initiation of
system shutdown sequence of the extraction system and treatment
system. If shutdown sequence is initiated, PLC will remotely
communicate condition to Operator.
c. PLC shall monitor water level in the air stripper clear well via an
ultrasonic level indicator (LE/LIT-301) and control the water level by
adjusting the pumping rate of the discharge pump (P-301) by
modulating the input signal to the variable frequency drive (VFD)
and, thereby, increasing or decreasing the pump speed to maintain
a predetermined operator-controlled level within the air stripper
clear well. If the water level should fall below the preset minimum
level and pump speed has been reduced to the preset minimum
speed, the PLC shall signal pump shutdown after operatoradjustable, but preset, time period. Pump shall remain shut down
until groundwater level returns to preset, but operator-adjustable
level above the preset minimum level. The air stripper clearwell
shall also be equipped with a high-level switch (LSH-301) and lowlevel switch (LSL-301). If water level in clearwell rises or lowers
causing either level switch to be triggered, PLC will be signaled. If
condition persists after an operator adjustable but preset time
delay, the PLC will signal initiation of system shutdown sequence of
the extraction system and treatment system. If shutdown sequence
is initiated, PLC will remotely communicate condition to Operator.
d. Air pressure (vacuum) shall be measured by pressure meter
PI/PIT-301 at the blower intake and transmitted to the PLC. PLC
will monitor the vacuum. Set points for low or high vacuum
conditions shall be established at PLC and interlocked with CP-501
and operation of blower. Low and high vacuum alarms shall be
System Operation Description
Section 17700
Statement of Work

PMG Phase 1 Interim Action
indicated at PLC and communicated to Operator, if pressure is
below low pressure set point or above high pressure set point. PLC
will signal blower and extraction system shutdown if condition
persists after preset but operator adjustable time delay. If blower
shutdown is initiated, PLC will remotely communicate condition to
Operator.
D.
Vapor Treatment Equipment
1. The theory of the operation and control system for the vapor treatment
system is described below.
a. Moisture Separator – An air moisture separator shall be located inline between the air stripper and blower. Liquid level in the
separator shall be controlled by high-, high-high- and low-level float
switches (LI/LIT-301). If level in the separator rises causing the
high-level float switch to be triggered, the integrated condensate
pump will be signaled to evacuate the separator into the building
dead-end sump. The condensate pump shall pump until the lowlevel float switch is triggered, signaling the condensate pump to
shut off. If the high-high-level switch is triggered, the PLC will be
signaled. PLC will signal treatment system and extraction system
shutdown if condition persists after preset but operator adjustable
time delay. If system shutdown is initiated, PLC will remotely
communicate condition to Operator.
b. Duct Heater – A duct heater shall be located in-line between the
blower and GAC vessels. Air temperature downstream of the duct
heater (at the intake to the GAC vessels) shall be measured by TT301. Air temperature shall be transmitted to, displayed, and
monitored by the PLC. PLC shall control air temperature entering
the GAC vessels by signaling the duct heater temperature
controller (TC-301) to adjust the heat input of the duct heater to
maintain a predetermined air temperature within the air duct at the
GAC vessel intake.
c. Vapor Treatment – Air flow through two GAC vessels (GAC-301
and GAC-302) shall be manually controlled with a 6-valve manifold
allowing operation in series or parallel configurations. Differential
pressure across the vessels shall be monitored manually by
pressure gauges PI-301/302/303.
E.
Other Equipment
1. A description of other equipment and controls associated with the
treatment system, treatment system building, or well vaults is
described below.
System Operation Description
Section 17700
Statement of Work
V - 133
PMG Phase 1 Interim Action
a. Building Sump/Sump Pump/Leak Detection – A dead-end sump
shall be located in the treatment building for secondary containment
of liquid spills or discharges. The sump will contain level switchs
(LE-501) that will trigger a high-level alarm and high-high level
switch. If liquid level in the sump rises causing the high-level switch
to be triggered, a system alarm will be signaled to the PLC and
identified on a red alarm light at CP-501 and remotely to the
Operator. If the high-high level switch is triggered, the PLC will be
signaled and the PLC shall initiate a shutdown of the extraction
system and treatment system. If system shutdown is initiated, PLC
will remotely communicate condition to Operator. The sump will
also be equipped with a sump pump (P-501). Sump pump shall be
manually operated by a hand switch (HS-502) on the sump pump
control panel (CP-502).
b. Well Vault Sumps/Sump Pumps/Leak Detection – A sump shall be
located in each well vault. The sumps will each be equipped with a
sump pump controlled by an integrated float switch. Each well
vault will also be equipped with a high-level switch (LSH101/102/103). If water level in the vault rises causing the high-level
switch to be triggered, an alarm will be signaled to the well control
panel which will de-energize all electrical equipment and systems in
the well vault and signal the PLC. PLC shall remotely communicate
condition to Operator.
c. Transfer Pump – A discharge pump (P-401) shall be plumbed
between the temporary holding tank and the air stripper
groundwater intake piping. The transfer pump shall be operated
manually by a hand-off-auto switch located on CP-501.
d. Temporary Holding Tank – A temporary holding tank shall be
located outside the treatment building and plumbed to the air
stripper outfall piping system. The temporary holding tank shall be
equipped with a high-level switch (LSH-402). If liquid level in the
tank rises causing the high-level switch to be triggered, CP-501 will
be signaled to shut down the discharge pump P-301, a system
alarm will be signaled on a red alarm light at CP-501, and the PLC
will be signaled to communicate the condition remotely to the
Operator.
e. Potable Water System
i. A temporary potable water supply system with tank, pump, and
pressure tank shall be located in the treatment building. The
system shall be manually controlled.
ii. An emergency shower and eyewash station shall be provided in
the treatment building. The station shall be plumbed to the
potable water supply system.
