APPENDIX I6 

SITE-SPECIFIC RESIDENTIAL CONSTRUCTION PLANS; TABLE OF 

RESIDENCES WITHIN 50 FEET OF WEP CONSTRUCTION RIGHT-OFWAY; SITE-SPECIFIC SCHOOL CONSTRUCTION PLANS 

Site-Specific Plans for Residences within 25 Feet

Northwest will work with each landowner/resident on an individual basis to ensure fair treatment during the time 

of construction. Site specifics will be worked out with individual landowners prior to construction. Construction 

stipulations will be negotiated with each landowner regarding specific measures that will be taken.

In general, Northwest Pipeline LLC (Northwest) plans to incorporate the following measures for residences within 

10 feet of the proposed workspace, which encompasses the construction right-of-way (ROW) and temporary extra 

workspace area (TEWA):

• Temporary chain-link and reinforced orange safety fencing will be placed between the residence and the

construction work area at a distance no less than 5 feet away from the foundation of the home.

• Temporary chain-link and reinforced orange safety fencing will be enclosed where needed to keep children

and pets away from construction workspace. Northwest will communicate with residents about the

placement and timing of temporary fencing.

• For areas where construction will inhibit driveways or access to the home, Northwest will contact the resident

prior to the fence installation to discuss the timing of temporary fencing installation and removal. Residents

will be able to access their homes when needed. Temporary rerouting of a driveway or entrance may be

required, and safety fencing may be needed between the entrance and the ROW or TEWA. These actions will

be relayed to the contractor. If a resident needs to be relocated for safety or other reasons, Northwest will

define details on an individual basis.

• Open trenches will be covered using steel (or similar material) plates each night before contract workers leave

the construction site. In densely populated areas, chain-link fencing will also surround the covered trench.

• Northwest will not remove any structures or buildings unless they inhibit construction. Structures or buildings

within Northwest’s existing permanent easement will not be permitted. Northwest will make

accommodations with landowners prior to removal of structures or buildings within TEWAs that are not

located in Northwest’s easement.

• Northwest will comply with local noise ordinances in these residential locations. Where there are additional

concerns, Northwest will work with individuals and local jurisdictions to mitigate the effect.

• In densely populated areas, Northwest intends to use methods of construction that limit the duration of

construction in one area. Stove piping (an open trench of only one pipe joint length) will be the primary

method of installation through densely populated areas. One or two pipe sections per day will be installed.

• Spoil will be stored in TEWAs or hauled offsite where tight areas do not allow for spoil storage on the ROW.

Topsoil will be segregated in all residential areas, and replaced upon completion.

• For residences within 50 feet of the construction workspace, temporary chain-link and reinforced orange

safety fencing will be installed near the home at the edge of the construction work area.

Northwest will apply the above measures to homes within 25 feet of the construction workspace where needed, 

or as agreed upon with the landowner.

Introduction

This Erosion Control and Revegetation Plan (ECRP) outlines the erosion control and revegetation procedures that 

Northwest Pipeline LLC (Northwest) will use during construction of the Washington Expansion Project (WEP). The 

intent of this ECRP is to outline methods and procedures that will be implemented to minimize erosion, control

sedimentation, and enhance revegetation success on all lands crossed by the WEP. The revegetation measures 

outlined in this ECRP have been prescribed to stabilize disturbed areas and to revegetate the right-of-way (ROW) 

to a condition that supports the preconstruction land uses as quickly as possible following construction.

This ECRP was developed using the Federal Energy Regulatory Commission’s (FERC’s) Upland Erosion Control, 

Revegetation, and Maintenance Plan (Upland Plan) (FERC, 2013a) and FERC’s Wetland and Waterbody 

Construction and Mitigation Procedures (Wetland and Waterbody Procedures) (FERC, 2013b). FERC’s Upland Plan 

and Wetland and Waterbody Procedures have been developed specifically for linear pipeline projects with the 

intent to minimize the extent and duration of project-related disturbance, minimize erosion, and enhance 

revegetation success. The Upland Plan and Wetland and Waterbody Procedures were developed through a public 

process that included input from state, federal, and local agencies, industry, and the general public. In addition, 

this ECRP incorporates recommendations provided by the Natural Resource Conservation Service (NRCS, 2012) 

and by the design standards for best management practices (BMPs) presented in the Western Washington 

Stormwater Management Manual (Washington Department of Ecology, 2012). The intent of these resources was

to identify structural and nonstructural practices that could be implemented during construction of the WEP to 

prevent and/or minimize, to the maximum extent practicable, the transport of sediment from the WEP site to 

drainage facilities, water resources, and adjacent properties.

1.1 Project Components

Northwest proposes to construct and operate the WEP, a capacity expansion to Northwest’s existing natural gas 

transmission facilities along the Interstate 5 (I-5) corridor in the state of Washington. The WEP consists of 

approximately 140 miles of 36-inch-diameter pipeline to be constructed in ten noncontiguous segments (loops) 

between Woodland and Sumas, Washington, in Cowlitz, Lewis, Thurston, Pierce, King, Snohomish, Skagit, and 

Whatcom counties. To the extent practicable, Northwest proposes to install the pipeline in its existing ROW to 

minimize environmental, residential, and other impacts. In addition to the pipeline, Northwest will upgrade five 

existing compressor stations. A complete description of the WEP and its purpose and need can be found in 

Revised Resource Report 1—General Project Description.

1.2 Schedule 

Northwest proposes to commence construction of the WEP in 2017 to meet the fourth quarter 2018 in-service 

schedule. 

During 2017, Northwest plans to install trenchless crossings such as horizontal directional drilling (HDD) or Direct 

Pipe on major waterbodies listed in Revised Table 1.2-1 in Revised Resource Report 1—General Project 

Description. This schedule allows for sufficient time to pursue permits for alternative crossing locations or 

methods to cross these rivers in the event trenchless installation methods are unsuccessful. An alternate crossing 

method or trenchless crossing at an alternate location would then be completed in 2018 during the WEP pipeline 

construction.

In 2017, Northwest plans to conduct clearing in some large forested areas on the Woodland Loop, Chehalis Loop, 

and in selected other locations ahead of the WEP pipeline construction to minimize overall workspace, temporary 

extra workspace area (TEWA) requirements, and impacts on landowners. TEWA requirements will be minimized 

by proposing a multiple-year construction schedule because the same work areas used to stage ROW logging 

activities and provide timber storage and decking space in 2017 could be used for pipeline construction activities

in 2018. Timber removal concurrent with pipeline construction would require additional TEWAs to work safely 

and efficiently, and potential clearing delays could force construction activities into the winter rainy season, which 

increases the potential for erosion and safety hazards. Therefore, scheduling construction activities over a 

multiple-year period will minimize winter construction requirements resulting from seasonal construction 

windows and allow greater flexibility to remove forested habitat during non-nesting seasons for species protected 

under the Migratory Bird Treaty Act.

Northwest anticipates initiating work at the five existing compressor stations in fourth quarter 2017. Both pipeline 

and compressor station work will be completed in fourth quarter 2018. Revised Table 1.2-1 in Revised Resource 

Report 1—General Project Description provides a general schedule for the WEP.
SECTION 2

Site Description

2.1 Pipeline Facilities

The aboveground facility installations and modifications (i.e., cross-over assemblies, mainline block valves, and

internal inspection device [pig] launchers/receivers) will be installed primarily within existing facility footprints or 

within the existing permanent ROW and will be permanently stabilized with gravel; therefore, these aboveground 

facilities are not discussed further. Temporary erosion control measures at these facilities will be installed as 

necessary during construction as determined by Northwest’s Environmental Inspector (EI) using the BMPs 

outlined in this ECRP.

2.2 Existing Site Conditions

The WEP generally runs along the interface of the Puget Lowland and Cascade Range physiographic provinces, 

occasionally crossing back and forth from one province to the other. Washington’s Cascade Range physiographic 

province consists of an active volcanic mountain range where Pliocene to recent uplift has resulted in relatively 

high topographic relief. The Cascade Range is typically divided into two sections, the North Cascades and the 

South Cascades. The WEP traverses the western boundary of both the North and South Cascades (Washington 

State Department of Natural Resources [DNR], 2012).The Puget Lowland physiographic province consists of a 

broad, low-lying region of subdued topography situated between the Cascade Range to the east and the Olympic 

Mountains and Willapa Hills to the west. The Puget Lowlands extend from the Canadian border southward to 

Eugene, Oregon, and the northern part of the Puget Lowlands is a flat glacial plain interrupted by the complex 

bays and inlets of Puget Sound (Lasmanis, 1991). The WEP area crosses nearly level glacial terraces and steepsided valley walls. 

The climate of the WEP area is tempered by air masses from the Pacific Ocean, which influence the climate 

throughout the year. Summers are fairly warm; hot days are rare. Winters are cool; snow and freezing 

temperatures are not common. During summer, rainfall is extremely light, and several weeks often pass without 

precipitation. During the rest of the year, rains are frequent, especially in late fall, winter, and spring. 

In the winter, the average temperature is approximately 40.7 degrees Fahrenheit (°F) and the average monthly 

minimum temperature is about 33.7°F (Western Regional Climate Center [WRCC], 2013). In the summer, the 

average temperature is about 63.6°F and the average monthly maximum temperature is approximately 76.2°F. 

Total annual precipitation is about 38.3 inches. Of the total annual precipitation, about 18 percent usually falls 

during the dry season from May through September. The average snowfall is approximately 4.7 inches, and 

thunderstorms occur about five to ten times each year, mostly in the summer. Winter storms in the WEP area 

bring strong and sometimes damaging winds approximately once every 2 years, and streams may rise above flood 

stage several times each year (WRCC, 2013). 

2.3 Proposed Pipeline Construction Activities

The WEP will be designed, constructed, operated, and maintained in accordance with the U.S. Department of 

Transportation (DOT) regulations in 49 Code of Federal Regulations (CFR) Part 192, “Transportation of Natural and 

Other Gas by Pipeline: Minimum Federal Safety Standards;” 18 CFR Part 2.6, “Guidelines to be Followed by 

Natural Gas Pipeline Companies in the Planning, Clearing, and Maintenance of Rights-of-Way and the 

Construction of Aboveground Facilities;” and other applicable federal and state regulations. In addition to the DOT 

requirements listed above, Northwest will also construct and reclaim the pipeline and aboveground facilities in 

accordance with FERC’s Upland Plan and Wetland and Waterbody Procedures.

Generally, the pipeline will be installed within the existing easement to avoid creating new ROW impacts. 

Exceptions were made in several locations to accommodate a more suitable crossing location. Waterbody 
2 SITE DESCRIPTION

2-2

crossings will be constructed as close to perpendicular to the axis of the waterbody channel as engineering and 

routing conditions permit. Banks of waterbodies will be returned to preconstruction contours. If Northwest 

cannot restore the waterbody banks to preconstruction contours, then banks will be restored to a stable angle 

using bioengineered approaches, as approved by the EI.

Pipeline construction will primarily occur in 2018. Northwest will prepare to receive materials and pipe at 

contractor and pipe storage yards when materials are procured from vendors and after the contractor and pipe

storage yards have been identified during easement negotiations. Revegetation will primarily occur during the fall 

of 2018. The general construction sequence is as follows:

• Preconstruction survey

• Installation of erosion control BMPs

• Clearing and grading

• Topsoil segregation

• Trenching, 26-inch pipeline removal (where necessary), and installation of 36-inch replacement pipeline

• Hydrostatic testing

• Restoration

Each step is described in more detail in the following sections.

2.3.1 Preconstruction Survey

The limits of disturbance will be clearly marked/staked prior to construction including the construction ROW, 

TEWAs, and access roads. Utility lines or other foreign line crossings will be located and marked to prevent 

accidental damage during pipeline construction. Sensitive areas to be protected from disturbance will be marked 

with highly visible construction sheeting and brightly colored flagging, or construction fence for equipment 

operators. Equipment will be allowed to enter and operate only within the delineated limits of disturbance and 

access roads. In addition, any state- or county-listed Class A or Class B noxious weed infestations will be mapped 

and flagged. The locations of the noxious weed infestations will be provided to the applicable county Noxious 

Weed Control Board. Flagging, signs, and other markings identifying the limits of disturbance will be maintained 

through all phases of construction and routinely checked by Northwest’s EI (see Section 3.0 for the EI’s 

responsibilities). Construction will generally use a 95-foot-wide construction ROW, with additional TEWAs 

required at designated locations such as at road or waterbody crossings and other areas where additional staging 

areas are required. A number of areas will require the construction ROWs to be reduced to 75 feet in width, such 

as in wetlands and in residential areas, to minimize disturbance. Where feasible, based on site-specific conditions 

and engineering constraints, TEWAs have been set back from wetland and waterbody boundaries to minimize 

impacts to wetland buffers and riparian areas consistent with the Wetland and Waterbody Procedures.

2.3.2 Installation of Erosion Control BMPs

Temporary erosion control measures will be installed in conjunction with clearing activities and prior to grading 

(initial soil disturbance). Installation of temporary erosion control measures prior to clearing is ineffective because 

the brush must be cleared to allow proper installation of the BMPs, and installed BMPs could be damaged during 

clearing activities. Installed erosion control BMPs will be routinely inspected and any damaged or temporarily 

removed BMPs will be replaced at the end of each working day or sooner as required by applicable permits and 

authorizations. Temporary erosion control measures will be maintained until the area disturbed during 

construction is stabilized (i.e., successful revegetation has been achieved) and approval is achieved from local and 

state agencies to remove the BMPs. Section 3.1 describes in detail the temporary erosion control BMPs that will 

be implemented during construction to minimize erosion and potential impacts from offsite sedimentation.

During any prolonged period of inactivity, such as the time between timber clearing and construction, the BMPs 

will be inspected once every calendar month as required by the project-specific Stormwater Pollution Prevention 

Plan. During this time, the soils will be temporarily stabilized with a combination of a thick layer of mulch, soil 

binders, and tackifiers, and then temporarily seeded. Depending on site conditions, straw wattles and compost 

socks may also be installed to control stormwater runoff velocity.
2 SITE DESCRIPTION

2-3

2.3.3 Clearing and Grading

The flagged limits of disturbance will be maintained throughout all construction phases and will be monitored by 

Northwest’s EI. Where feasible, previously identified noxious weed infestations will be removed prior to landclearing activities. Noxious weeds and soil contaminated with noxious weeds will be transported offsite only in 

appropriate containers to prevent the migration of noxious weeds. Brush and trees within the construction ROW

and TEWAs will be felled or sheared so as to prevent damage to adjacent trees and structures and will be felled 

away from wetlands and waterbodies. Any debris entering a waterbody as a result of felling and yarding of timber 

will be removed as soon as practical after entry into the waterbody. Any logs firmly embedded in the bed or bank 

of waterbodies that are in place prior to felling and yarding of timber will not be disturbed, unless they prevent 

trenching and fluming operations. Any existing logs that are removed from waterbodies to construct the pipeline 

crossing will be returned to the waterbody after the pipeline has been installed and backfilling is complete, when

the banks are being restored. Logs and slash will not be yarded across DNR Type F streams and, where possible, 

across DNR Type N streams. Temporary crossings of Type N streams will be installed such that the direction of log 

movement between stream banks shall be designed to minimize sediment delivery to streams. Landings for 

clearing operations will not be located in wetlands, and, where feasible, logs yarded out of wetlands or riparian 

zones will be skidded with at least one end suspended above the ground to minimize soil disturbance. 

Construction through these areas will be minimized and the logs will be transported to minimize damage to 

adjacent trees and vegetation, where possible. All clearing operations near waterbodies will follow conditions 

specified in the WEP’s Hydraulic Project Approval (HPA) issued by the Washington Department of Fish and Wildlife 

(WDFW).

No vegetation outside of the ROW will be cleared between the TEWAs and the edges of stream banks and/or 

wetlands. Grading of the construction ROW in upland areas shall be limited to the minimum required to provide a 

safe working area necessary to construct the pipeline. Vegetation in wetlands will be cut off at ground level, 

leaving existing root systems in place. Pulling of tree stumps and grading activities will be limited to areas directly 

over the trench. Northwest will not grade or remove stumps or root systems from the rest of the ROW in 

wetlands unless it is determined that safety-related construction constraints require removal of tree stumps from 

under the working side of the ROW. Minimizing stump and root system removal will accelerate restoration efforts 

by allowing sprouting species to reestablish from existing root systems.

2.3.4 Topsoil Segregation

The potential mixing of topsoil with subsoil from construction activities could result in a loss of fertility of the soil. 

To prevent mixing of the soil horizons or incorporation of excess rock into the topsoil, topsoil will be segregated. 

FERC’s Upland Plan requires topsoil segregation in (1) all residential areas; (2) actively cultivated or rotated 

agricultural lands; (3) pastures and hayfields; and (4) other areas at the landowner’s request. In these areas, 

FERC’s Upland Plan requires either full ROW or trench and subsoil storage area stripping. Segregated topsoil will 

be stockpiled separately from subsoil in accordance with FERC’s Upland Plan. Segregated topsoil stockpiles will be

covered during periods of inactivity (more than 14 days) to protect the soil from noxious weed seeds and other 

propagative plant parts. In deep soils (more than 12 inches of topsoil), Northwest will segregate at least 12 inches 

of topsoil. In soils with less than 12 inches of topsoil, Northwest will make every effort to segregate the entire 

topsoil layer, as determined by Northwest’s EI.

FERC’s Wetland and Waterbody Procedures address topsoil segregation in wetlands. In wetland areas, FERC 

requires the top 12 inches over the trenchline to be salvaged, except in areas where standing water or saturated 

soils are present.

2.3.5 Trenching and Installation of 36-inch Pipeline

Northwest will excavate a trench, remove the existing pipe (if necessary), install the new pipe within the

excavated trench, and backfill the trench. After installation of the 36-inch pipeline and prior to backfilling,

Northwest will install trench plugs (see Drawing 1408.34-X-0011 in Attachment 1) consistent with the 

requirements of FERC’s Upland Plan (Section IV.F.2). Trench plugs will be installed at the base of slopes adjacent 

to wetlands and waterbodies and where needed to avoid draining of wetlands. Trench plugs may be constructed 
2 SITE DESCRIPTION

2-4

from sandbags or foam. Topsoil will not be used to fill the bags. Trench plugs will be installed on slopes to 

minimize water flow down the trench line to prevent potential subsurface erosion and to maximize stability.

The source of backfill material will be the material removed from the trench for placement of the pipe. This 

material, less the volume occupied by the 36-inch pipe, will be returned to the trench.

2.3.6 Hydrostatic Testing

After backfilling, the pipeline will be hydrostatically tested in accordance with DOT regulations to ensure that the 

system is capable of operating at the design pressure as described in Section 4.1 of this ECRP. Should a leak or 

break occur, the line will be repaired and retested until the specifications are achieved. Hydrostatic test water will 

be discharged in a manner to prevent erosion from scour and to prevent sedimentation of adjacent wetlands or 

waterbodies. The test water will be discharged into a straw bale structure to dissipate energy and filter the test 

water, and the filtered water will be discharged as overland sheet flow (see Drawing 1408.34-X-0012 in 

Attachment 1).

2.3.7 Restoration

After the pipeline is backfilled and tested, disturbed areas will be restored as nearly as possible to their original 

contours. Permanent erosion control measures will be installed as discussed in Section 3.0 of this ECRP, and 

revegetation will be performed as outlined in Section 5.0.

2.4 Potential Sources of Contamination from Construction

The potential sources of pollutants that could be discharged in the receiving waterbodies through contact with 

stormwater during construction activities include the following:

• Vehicle and equipment fueling and maintenance areas

• Materials handling/loading and unloading areas

• Erosion (wind, water)

• Tracking from equipment

• Grading and site preparation

• Drilling

• Trenching

• Hazardous material storage areas

• Storage yards

• Mobile equipment

• Painting

2.4.1.1 Vehicle and Equipment Fueling and Maintenance

Fueling and minor maintenance of vehicles and equipment may be conducted on some construction sites. These 

activities can be potential sources of leaks and incidental spills of fuel (during fueling), oil, and grease.

2.4.1.2 Materials Handling/Loading and Unloading Areas

Materials handling/loading and unloading activities are common on construction sites. Materials may spill or leak 

during loading and unloading, and may collect in the soil or other surfaces and be carried away in stormwater. 

Machines used to unload materials also may be a source of stormwater pollution.

2.4.1.3 Erosion

Erosion is caused where soil is exposed to water or wind. Erosion can be caused by many construction-related 

activities, such as removing vegetation, compacting or disturbing the soil, changing natural drainage patterns, and 

covering the ground with impermeable surfaces. Erosion is a source of sediment in stormwater.
2 SITE DESCRIPTION

2-5

2.4.1.4 Tracking 

Construction equipment and construction vehicles have the potential to track soils from the construction project 

into public roadways. Any soils tracked off the construction sites may be a possible source of sediment in 

stormwater.

2.4.1.5 Grading and Site Preparation

Grading and site preparation may be required at some locations and can be contributors of suspended solids 

concentration in stormwater. The possibility of erosion exists throughout the grading and site preparation phases 

of construction projects until construction is complete.

2.4.1.6 Drilling

Trenchless crossings such as HDD or Direct Pipe will be used at several waterbody crossings. Mud rotary 

techniques will be used to transport the cuttings to bins. The rotary mud (inert bentonite) could become a 

potential source of sediment-laden water if not managed appropriately.

2.4.1.7 Trenching 

During the installation of pipeline sections, open trenching will be used throughout the route. During this type of 

installation, the stockpiled material will be exposed, and it could be a source of sediment if not managed 

appropriately.

2.4.1.8 Hazardous Material Storage Areas

Hazardous material storage areas have the potential to release hazardous substances that may pose a threat to 

human health or the environment. Hazardous materials may be toxic, corrosive, ignitable, explosive, or chemically 

reactive. There is a potential for hazardous materials to be stored on construction sites. Outdoor storage areas 

include drums, sheds, clamshells, and yellow flammable cabinets.

2.4.1.9 Storage Yards

Storage yards may contain equipment, construction materials, hazardous material storage areas, and construction 

debris that, when exposed to runoff, may pollute stormwater. A wide range of contaminants (metals, oil, and 

grease) may enter the environment by washing off or dissolving from stored material.

2.4.1.10 Mobile Equipment

Portable tanks and other mobile equipment are used extensively on construction sites. This equipment may 

generate fuel or oil leaks or spills. Closed portable tanks and bins will be used to store wastes generated during 

the WEP.

2.4.1.11 Painting

During painting and paint removal activities, materials may be used (and wastes created) that are harmful to 

humans and the environment. Pollutants may include solvents, solids, and metals. Any waste generated from 

these activities would be captured and removed following federal and state requirements.
SECTION 3

3-1

Best Management Practices

This ECRP will be used by contractors as a primary construction reference for the WEP. It provides site-specific 

directions for installing temporary and permanent erosion control measures (or BMPs) to prevent or minimize 

erosion. Attachment 1 provides drawings of typical BMPs that may be used during construction. BMP materials 

will be stored at the WEP’s proposed yards. 

Northwest will employ a team of EIs for the WEP. An EI will be onsite during active construction and will have peer 

status with all other utility inspectors. All EIs will have authority to stop activities that violate the measures set 

forth in this ECRP as well as other authorizations and will have the authority to order corrective action. At a 

minimum, the EIs will be responsible for:

• Ensuring compliance with the measures set forth in this ECRP, the requirements of FERC’s Upland Plan, FERC’s

Wetland and Waterbody Procedures, Washington’s Noxious Weeds regulations in Revised Code of

Washington (RCW) 17.10, 18 CFR Part 380.15(e) (3), and all other environmental permits and approvals, as

well as environmental requirements in landowner agreements.

• Identifying, documenting, and overseeing corrective actions, as necessary, to bring an activity back into

compliance.

• Verifying that the limits of authorized construction work areas and locations of access roads are properly

marked before clearing.

• Verifying the location of signs and highly visible flagging marking the boundaries of sensitive resource areas,

waterbodies, wetlands, areas of known noxious weed infestations, or areas with special requirements along

the construction work area.

• Identifying areas needing noxious weed control and monitoring the results of removal efforts.

• Identifying erosion/sediment control and stabilization needs in all areas.

• Locating dewatering structures and slope breakers to ensure they will not direct water into sensitive areas.

• Verifying that trench dewatering activities are located such that water is allowed to infiltrate whenever

possible, turbid water does not reach waters of the state, and dewatering does not result in the deposition of

sand, silt, and/or sediment. If such deposition is occurring, the dewatering activity shall be stopped and

corrective action taken to prevent reoccurrence.

• Testing subsoil and topsoil in pastures, active agricultural fields, and residential areas crossed by the WEP to

measure compaction, and determining the need for corrective action.

• Advising the Chief Inspector when conditions (such as wet weather) make it advisable to restrict construction

activities to avoid excessive rutting.

• Ensuring restoration of contours and topsoil.

• Approving imported fill material (including rock, gravel, or soils) for use in residential areas and verifying that

the fill material is inspected for noxious weeds and soil pests.

• Determining the need for erosion controls and ensuring that they are properly installed, as necessary, to

prevent sediment flow into wetlands, waterbodies, sensitive areas, and onto roads. This includes evaluating

controls prior to a predicted storm event, whenever possible, and installing additional measures as needed to

control stormwater and sediment.

• Inspecting and ensuring the maintenance of temporary erosion control measures at least daily in areas of

active construction or equipment operation, on a weekly basis in areas with no construction or equipment
3 BEST MANAGEMENT PRACTICES

3-2

operation, and within 24 hours of each 0.5-inch or greater rainfall. Inspections will be recorded and records 

maintained for review upon request.

• Ensuring the repair of all ineffective temporary erosion control measures as soon as possible but not longer

than 24 hours after identification.

• Keeping records of compliance with the conditions of all environmental permits and approvals (including the

measures set forth in this ECRP) during active construction and restoration.

• Identifying areas that should be given special attention to ensure stabilization, restoration, and the reduction

of the spread of noxious weeds after the construction phase.

3.1 Temporary Erosion Control Procedures

Temporary erosion controls will be installed immediately after initial disturbance (clearing) and will be properly 

maintained throughout construction and reinstalled as necessary until replaced by permanent erosion controls or 

until restoration is complete. Near waterbodies and wetlands, it will be determined in the field by the EI if it is 

necessary to install temporary erosion control measures (such as sediment barriers) prior to initial disturbance to 

minimize the potential for sediment to enter a wetland or waterbody. 

3.1.1 Construction Ingress and Egress

Northwest has identified ingress/egress points using existing public and private roads that are crossed by the 

ROW. All access roads are shown on the Aerial Maps in Revised Appendix 1A and on the alignment sheets 1C of

Revised Resource Report 1—General Project Description. Construction traffic will move up and down the 

construction ROW as much as possible.

In designated areas, as determined by the EI, Northwest will install construction entrances at ROW access points 

that intersect paved roads to reduce sediment transport onto the roadway. A typical drawing of a construction 

entrance access pad is provided as Drawing 1408.34-X-0001 in Attachment 1. 

3.1.2 Sediment Barriers

Sediment barriers will be used to confine sediment to the construction ROW and will be constructed of silt fence, 

straw bales, or straw wattles (see Drawing 1408.34-X-0002 in Attachment 1). Silt fence will be used where 

sediment barriers are required parallel to the ROW. Straw bales (weed-free) will be used in locations where 

sediment barriers are required to cross the construction ROW along the travel lane, such as at waterbody and 

wetland crossings. Straw wattles may also be used in appropriate areas as determined by the EI to reduce runoff 

velocity and confine sediment to the construction ROW. These structures will generally be placed as follows:

• At the base of slopes adjacent to road, wetland, and waterbody crossings where sediment could flow from the

construction ROW onto the road surface or into the wetland or waterbody

• Adjacent to wetland and waterbody crossings, as necessary, to prevent sediment flow in the wetland

consistent with the requirements of FERC’s Wetland and Waterbody Procedures

• On the downslope side of the ROW where it traverses steep side slopes

Drawing 1408.34-X-0003 in Attachment 1 shows the placement of temporary sediment barriers adjacent to road 

crossings. An example of sediment control in ditches and swales is shown on Drawing 1408.34-X-0004 in 

Attachment 1. Examples of sediment barrier installations during construction at wetlands and streams are shown 

on Drawings 1408.34-X-0005, -0006, and -0007 in Attachment 1. Northwest’s EI will determine where it may be 

necessary to provide added protection using sediment barriers to ensure that runoff is properly treated and that 

sediment is contained on the ROW. 

The EI will inspect temporary erosion control structures at least on a daily basis in areas of active construction and 

equipment operation. In areas where active construction and equipment operation are not occurring, inspections 

will be made at least weekly. All structures will be inspected by the EI within 24 hours of each 0.5-inch or greater 
3 BEST MANAGEMENT PRACTICES

3-3

rainfall; however, state and other local jurisdictions may require more frequent inspection of erosion control

structures. The EI will be responsible for ensuring that ineffective temporary erosion control measures are 

repaired as soon as possible but no more than 24 hours after discovery. Whenever possible, the EI will inspect 

erosion control measures in advance of predicted storm events and take preventative measures to minimize the 

potential for off-ROW sedimentation. Temporary sediment barriers will be maintained in place until permanent 

revegetation measures are successful or until the upland areas adjacent to wetlands, waterbodies, or roads are

stabilized. The structures will be removed once the area has been successfully stabilized.

3.1.3 Storm Drain Inlet Protection

The EI will assess all storm drain inlets downslope and within the approved work areas and determine if potential 

runoff from the WEP could reach a storm drain. Where necessary, storm drain inlets will be protected with 

temporary devices to prevent sediment from entering them. There are various inlet protection filters that are 

effective in keeping sediment-laden water from entering a storm drainage system, such as block and gravel filters, 

gravel and wire-mesh filter barriers, or bag barriers filled with various filtering media, which are placed around 

the inlet to protect the storm drain. Drawing 1408.34-X-0014 provides examples of a few common inlet protection 

methods.

3.1.4 Temporary Slope Breakers and Runoff Controls

3.1.4.1 Temporary Slope Breakers

Northwest will install temporary slope breakers to reduce runoff velocity and concentrated flow, and to divert 

water off the construction ROW to avoid excessive erosion (see Drawing 1408.34-X-0008 in Attachment 1). 

Temporary slope breakers may be constructed of materials such as soil, silt fence, staked straw bales, or sand 

bags. The outfall of each temporary slope breaker will be to a stable, well-vegetated area or to an energydissipating device at the end of the slope breaker and off the construction ROW. The outfall of the slope breakers 

will be positioned to avoid sedimentation of wetlands, waterbodies, and other sensitive areas. Northwest will use

FERC’s Upland Plan (Section IV.F.1.b.) for spacing of temporary and permanent slope breakers for WEP. 

3.1.4.2 Runoff Controls

Interception of surface water on slopes reduces the possibility of erosion. Interceptor dikes and swales may be 

used to intercept storm runoff from undisturbed areas above disturbed areas or slopes and convey the runoff to 

stable points away from exposed soils. Stormwater runoff entering the construction ROW or TEWAs will be 

controlled to minimize erosion of disturbed areas and exposed cuts and fills. The EI will determine appropriate 

runoff control measures depending on site-specific and anticipated weather conditions. Potential control 

measures may include berms or interceptor dikes, swales, and piped slope drains as shown on Drawings 1408.34-

X-0015 and 1408.34-X-0016 (see Attachment 1).

3.1.5 Mulch

Although not expected, if it becomes necessary to delay final cleanup, including final grading and installation of 

permanent erosion control measures, beyond 20 days (10 days in residential areas) after the trench is backfilled in 

a specific area, Northwest will apply mulch on all disturbed slopes before seeding (FERC’s Upland Plan IV. F.4.a.). 

Mulch will also be applied if construction and restoration activities are interrupted for extended periods. In these 

areas, mulch will be applied uniformly over the area to cover the ground surface at a rate of 2 tons per acre of 

weed-free straw or 1 ton per acre of sterilized weed-free wood-fiber hydromulch. In addition, the mulch 

application rate will be increased to 3 tons per acre on steep slopes and all slopes within 100 feet of waterbodies

and wetlands. The mulch will consist of weed-free straw or sterilized weed-free wood-fiber hydromulch.

Construction is scheduled to occur primarily in the dry season; however, if in the wet season (October 1 to 

April 30) an area is to remain unworked for more than 2 consecutive days, the area will be covered or appropriate 

BMPs installed to minimize erosion potential based on soil type, slope gradient, anticipated weather conditions, 

and other factors. The installation of BMPs, as determined by the EI, will retain sediment onsite or treat/filter 

runoff before it leaves the construction ROW or TEWA. BMPs may include berms or sediment barriers. Temporary 
3 BEST MANAGEMENT PRACTICES

3-4

coverings may include weed-free straw or sterilized weed-free wood-fiber hydromulch materials or the 

application of plastic or tarps (see Drawing 1408.34-X-0017 in Attachment 1).

3.1.6 Erosion Control Fabric

Northwest will install erosion control fabric (such as jute or excelsior) on stream banks at the time of recontouring 

(see Drawing 1408.34-X-0009 in Attachment 1). The fabric will be anchored using staples or other appropriate 

devices. The erosion control fabric to be used on stream banks and steep slopes will be designed for the proposed 

use and will be approved by the EI.

3.1.7 Dust Control

During summer construction in the WEP area, fugitive dust may be a potential impact along the construction 

ROW, especially where construction occurs in residential or wetland/waterbody areas. To control dust the EI will 

limit traffic speeds and require watering, if necessary. Watering trucks will spray only enough water to control the 

dust or to reach the optimum moisture content of the soil for compaction. Run-off will not be generated during 

this operation. Dust will be controlled on paved roadways by sweeping (either by machine or hand). During 

sweeping, the EI will determine if water needs to be sprayed to control dust. Any sediment generated from 

sweeping will be disposed of properly. Water for dust control will be obtained from a municipal source.

3.1.8 Waterbody and Wetland Crossings

The following construction methods and BMPs will be included at waterbodies and wetlands, in accordance with 

FERC’s Upland Plan and Wetland and Waterbody Procedures. 

3.1.8.1 Waterbody Crossings

All intermittent waterbody crossings will be completed using dry, open-cut procedures if the waterbody is flowing 

at the time of construction. Dry, open-cut procedures may include dam-and-pump or flume crossing techniques 

(see Drawings 1408.34-0006 and 0007 in Attachment 1) consistent with the requirements of federal, state, and 

local agencies with specific authority and expertise to regulate impacts from the WEP. Waterbody crossings will 

be made generally perpendicular to the axis of the waterbody channel. TEWAs have not been located within

50 feet of waterbody boundaries where feasible, based on site-specific conditions (i.e., topographic or 

engineering constraints) consistent with FERC’s Wetland and Waterbody Procedures (Sections V.B.2.a. and 

V.B.3.b.). Northwest has proposed alternative measures where a TEWA setback from a wetland or waterbody 

could not be maintained.

One perennial waterbody crossing at the Toutle River will be completed using wet, open-cut methods. Wet, opencut methods may include dam diversions of the waterbody to create a dry work space. The wet, open-cut 

methods will be completed in a manner consistent with the requirements of federal, state, and local agencies 

with specific authority and expertise to regulate impacts from the WEP. Similar to dry, open-cut methods, 

waterbody crossings will be made generally perpendicular to the axis of the waterbody channel. TEWAs have not 

been located within 50 feet of waterbody boundaries where feasible, based on site-specific conditions (i.e., 

topographic or engineering constraints), consistent with FERC’s Wetland and Waterbody Procedures (Sections 

V.B.2.a. and V.B.3.b.). Northwest has proposed alternative measures where a TEWA setback from a waterbody is 

required. 

Northwest will use temporary construction bridges during all phases of construction to cross intermittent 

waterbodies. Temporary construction bridges will be designed according to FERC’s Wetland and Waterbody 

Procedures as well as according to conditions required by the U.S. Army Corps of Engineers, WDFW, and local 

jurisdictions. The temporary equipment bridges will be constructed to maintain unrestricted flow and to prevent 

soil from entering the waterbody. Soil will not be used to stabilize equipment bridges. Bridges will be designed to 

withstand and pass the highest flow expected to occur while in place, and, where feasible, bridges will be 

designed to span the ordinary high water mark. Temporary bridges may consist of:

• Equipment mats and culvert(s)

• Equipment mats or railroad car bridges without culverts
3 BEST MANAGEMENT PRACTICES

3-5

• Clean rock fill and culvert(s)

• Flexi-float or portable bridges

Northwest may use other alternatives for equipment bridges that achieve the same performance and objective. 

Drawing 1408.34-X-0010 in Attachment 1 provides a typical drawing of a temporary crossing bridge. Bridges will 

be removed as soon as possible after permanent seeding. If there will be more than one month between final 

cleanup and the beginning of permanent seeding and reasonable alternative access to the ROW is available, 

equipment bridges will be removed as soon as possible after final cleanup.

Sediment barriers will be installed immediately after initial disturbance of the waterbody or adjacent upland. 

Sediment barriers will be properly maintained throughout construction and reinstalled as necessary (such as after 

backfilling the trench) until replaced by permanent erosion controls or until restoration of adjacent upland areas 

is complete and revegetation has stabilized the disturbed areas. During restoration, waterbody banks will be 

returned to preconstruction contours and erosion control matting will be installed as directed by the EI (see 

Drawing 1408.34-0009 in Attachment 1). Bank stabilization measures for the river crossings will be addressed 

prior to construction.

3.1.8.2 Wetland Crossings

Wetlands will be crossed in accordance with FERC’s Wetland and Waterbody Procedures except where an 

alternative measure has been proposed. Drawing 1408.34-X-0005 in Attachment 1 shows the typical wetland 

crossing methods that will be used. Wetlands crossed or that are in proximity to the WEP are shown on the

alignment sheets in Revised Appendix 1C of Revised Resource Report 1—General Project Description. 

Sediment barriers will be installed immediately after initial disturbance (clearing) of the wetland or adjacent 

upland. Sediment barriers will be properly maintained throughout construction and reinstalled as necessary (such 

as after backfilling of the trench). Where necessary, sediment barriers will be installed across the entire 

construction ROW immediately upslope of the wetland boundary to prevent sediment flow into the wetland. 

Where wetlands are adjacent to the construction ROW, sediment barriers will be installed along the edge of the

construction ROW, as necessary, to prevent sediment flow into the wetland. These sediment barriers will be 

removed after restoration is complete and revegetation has stabilized the disturbed areas.

As stated above, where feasible, based on site-specific conditions (i.e., topographic or engineering constraints), 

Northwest has designed each crossing such that TEWAs are not closer than 50 feet from wetland boundaries, 

consistent with FERC’s Wetland and Waterbody Procedures (VI.B.1.a. and b.). Northwest has proposed an 

alternative measure from FERC’s Wetland and Waterbody Procedures because of site-specific conditions as shown 

in Revised Table 1.3-4 in Revised Resource Report 1—General Project Description. 

In wetlands where standing water or saturated soils are present, or if construction equipment would cause ruts or 

mixing of the topsoil and subsoil in wetlands, Northwest will use low-ground-weight construction equipment or 

will operate normal equipment on timber riprap or standard prefabricated equipment mats. Equipment mats 

distribute the weight of heavy equipment across a broader area. Rocks, soil imported from outside the wetland, 

tree stumps, or brush riprap will not be used to support equipment on the construction ROW. If trees are used as 

timber riprap or equipment mats to support equipment in saturated areas, they will be obtained from clearing 

operations and will not be cut outside of the approved construction work areas. Where timber riprap is used, 

Northwest will attempt to use no more than two layers of riprap to support equipment on the construction ROW. 

All materials used to support equipment on the construction ROW will be removed after construction.

The duration of construction-related disturbance within wetlands will be minimized and construction equipment 

operating in wetland areas limited to that needed to clear the ROW, dig the trench, remove the pipe, fabricate 

and install the pipe, backfill the trench, and restore the ROW. All other construction equipment will use access 

roads located in upland areas to the maximum extent practicable. Where there is no upland access road available, 

Northwest will limit all other construction equipment to one pass through the wetland using the ROW if the area 

is not properly matted and stabilized. 
3 BEST MANAGEMENT PRACTICES

3-6

3.1.8.3 Waterbody and Wetland Best Management Practices

Additional BMPs to be included at waterbodies and wetlands are as follows:

• Employ and monitor specific measures to ensure that sediment does not build up on temporary construction

bridges, thus minimizing entrance of sediment into adjacent waterbodies.

• For streams flowing at the time of crossing, assume fish presence and implement alternate dry-crossing

techniques (dam-and-pump, flumed, aerial, or trenchless methods) unless a site-specific plan drawing and

method is approved by FERC and appropriate agencies.

• For major waterbody crossings (greater than 100 feet), adhere to the site-specific plan drawings provided in

the Waterbody Crossing Plan.

• Locate TEWA at least 50 feet back from waterbody boundaries unless a reduced setback is requested on a

site-specific basis, where there is no woody riparian cover within 50 feet back from the waterbody, and an

alternative measure is approved by appropriate agencies.

• Maintain adequate flow rates throughout construction for aquatic life and to prevent the interruption of

existing downstream uses.

• Restrict spoil placement near surface waters to the construction ROW at least 10 feet from the water’s edge

or within additional extra workspaces placed at least 50 feet from the water’s edge.

• All equipment parked overnight and/or being fueled must be at least 100 feet from a waterbody or in an

upland area at least 100 feet from a wetland boundary.

• In certain instances, refueling or fuel storage may be unavoidable due to site-specific conditions or unique

construction requirements (e.g., continuously operating pumps or refueling within wetlands). The following

precautions will be taken when refueling within 100 feet of wetlands or waterbodies:

− Adequate amounts of absorbent materials and containment booms will be kept on hand by each

construction crew to enable the rapid cleanup of any spills. 

− If fuel must be stored within wetlands or near streams for refueling of continuously operating pumps, 

adequate secondary containment will be employed. 

− Secondary containment structures will be lined with suitable plastic sheeting. Provide a containment 

volume of at least 150 percent of the storage vessel and allow for at least 1 foot of freeboard.

− Northwest will provide adequate lighting at sensitive fueling/storage locations.

• Northwest will not store hazardous materials (including chemicals, fuels, and lubricating oils) within 150 feet

of a wetland, waterbody, or designated municipal watershed area. This applies to storage of these materials

and not to normal operation or use of equipment in these areas.

• Concrete coating activities will not be performed within 100 feet of a wetland or waterbody boundary unless

the location is an existing industrial site designated for such use or an alternative measure has been approved.

• Northwest will structure operations in a manner that provides for the prompt and effective cleanup of spills of

fuel and other hazardous materials. At a minimum, Northwest and its contractors will:

− Ensure that each construction crew (including cleanup crews) has on hand sufficient supplies of absorbent

and barrier materials to allow the rapid containment and recovery of spilled materials and knows the 

procedure for reporting spills.

− Ensure that each construction crew has on hand sufficient tools and material to stop leaks.

− Maintain a list of the contact names and telephone numbers for all local, state, and federal agencies 

(including, if necessary, the U.S. Environmental Protection Agency National Response Center) that must 

be notified of a spill.
3 BEST MANAGEMENT PRACTICES

3-7

− Follow the requirements of those agencies in cleaning up the spill, excavating and disposing of soils or 

other materials contaminated by a spill, and collecting and disposing of waste generated during spill 

cleanup.

3.1.8.4 Prohibited Practices

Many commonly applied BMPs have unacceptable levels of short- or long-term risk to aquatic species and habitat. 

Based on risk to species and habitat, Northwest will not use the following practices at any waterbody crossing 

sites unless there is no practical alternative to protect the integrity of the stream bank or safety of the pipeline:

• Grubbing in areas outside of the trench; grubbing is defined as the mechanical removal of roots and organic

matter that occur below the ground surface

• Bank hardening methods for the purpose of stream bank stabilization (unless tying into existing hardened

banks), such as:

− Gabion baskets

− Blanket riprap

− Articulated concrete blocks

− Concrete

• Concrete armoring anywhere in the active stream channel

• Use of temporary culverts or other streambed or floodplain fill as part of a temporary equipment bridge

• Upgrades of an existing road crossing over waterbodies

• Permanent installation of nonbiodegradable and/or nonwoven geotextile fabrics

• Chemical soil stabilizers on banks or adjacent slopes during any phase of construction or restoration

• Herbicides for treating noxious weeds within Endangered Species Act streams

3.1.9 Rugged Topography

The potential for surface erosion in areas of moderately sloping ground is high, and during construction the ROW 

in these areas will require substantial grading to provide a safe working plane. During restoration, these areas will 

be regraded to a stable configuration to minimize erosion and facilitate long-term maintenance. This ECRP 

provides the various BMPs that will be used, as necessary, to ensure erosion is minimized and slopes are 

revegetated and properly stabilized. 

Northwest has developed, implemented and maintained a comprehensive geologic hazard identification, 

characterization and mitigation program throughout its pipeline system, including the existing I-5 corridor 

between Woodland and Sumas, Washington. The Northwest geologic hazards program was established in part to 

address and mitigate the potential adverse effects of landslides and slope instability. A more detailed discussion 

of this program, and mitigation and monitoring activities implemented by Northwest for known geohazard areas 

is provided in Revised Resource Report 6—Geological Resources. 

3.1.10 Spill Prevention and Equipment Fueling and Maintenance

Northwest has developed a Spill Plan for Oil and Hazardous Materials (Spill Plan, Appendix 2E) that describes

measures to prevent and control any inadvertent spill of hazardous materials such as fuels, lubricants, and 

solvents that could contaminate soils and affect water quality. The Spill Plan will be updated with site-specific 

information prior to construction. All WEP construction employees will receive Spill Plan training.

Equipment fueling and storage of oil, fuel, or other materials near waterbodies or wetlands could create a soil 

contamination and water quality impact if a spill were to occur. Leaks from equipment and vehicles could also 

cause impacts to surface waters. Maintenance and equipment storage will take place along the entire 

construction ROW; however, certain areas are restricted from these activities. Hazardous materials, chemicals,

fuels, and lubricating oils will be stored in upland areas at least 100 feet from waterbodies and wetlands in 
3 BEST MANAGEMENT PRACTICES

3-8

accordance with FERC’s Wetland and Waterbody Procedures. Restricted areas for storage of these materials will 

be clearly marked in the field. Concrete coating, refueling, and equipment maintenance activities will also be 

conducted according to FERC’s Wetland and Waterbody Procedures. Concrete trucks will not be washed on the 

ROW. All hazardous materials will be handled in accordance with the Spill Plan. If an unanticipated spill occurs

during construction, Northwest will implement the procedures outlined in the Spill Plan.

3.1.11 Material Delivery and Storage

Northwest will use contractor and pipe storage yards that will be identified and acquired during easement 

negotiation for the WEP for material delivery and storage. Materials will be brought onto the ROW as they are 

needed and will be located away from waterbodies and wetlands. Storage yards and construction equipment will 

be routinely inspected for noxious weeds. Construction equipment will be cleaned as needed to prevent 

mobilization of noxious weeds into the construction area. Secondary containment will be provided for liquids.

3.2 Permanent Erosion Control Measures 

Permanent erosion control measures that will be used to reduce pollutants in stormwater discharges will be 

implemented after all construction phases have been completed. Post-construction BMPs consist of permanent 

features and operational practices designed to minimize pollutant discharges, including sediments, from the site 

after the WEP is completed.

3.2.1 Trench Breakers

Trench breakers will be installed in the trench on slopes prior to backfilling to prevent water from flowing along 

the pipeline and eroding trench backfill materials (see Drawing 1408.34-X-0011 in Attachment 1). Northwest will 

use FERC’s Upland Plan (Section V.B.1.d.) to determine spacing of temporary and permanent trench breakers for

the WEP unless directed otherwise by the EI or authorized company representative.

Where the pipeline trench may drain a wetland, trench breakers will be installed and/or the trench bottom sealed 

as necessary to maintain the original wetland hydrology. Northwest will install a trench breaker at the base of 

slopes near the wetland boundary between the wetland and adjacent upland area. A permanent slope breaker 

and a trench breaker will be installed at the base of slopes near the boundary between the wetland and adjacent 

upland areas. The trench breaker will be installed immediately upslope of the slope breaker. Trench breakers will 

consist of foam or approved sacks filled with a minimum 0.6 cubic feet of sand. They will be keyed into the trench 

sidewall where determined necessary by the EI or authorized company representative.

3.2.2 Permanent Slope Breakers

As required by FERC’s Upland Plan, slope breakers (water bars) will be installed with a 2 to 8 percent outslope, 

and flow will be diverted to a stable area. If a stable area is not present, a temporary energy-dissipating device will 

be installed at the end of the breaker. The frequency of permanent slope breakers will be based on FERC’s Upland 

Plan standards; however, state and other local jurisdictions may require a different slope breaker technology. 

The EI or authorized representative may modify the spacing based on site-specific characteristics such as slope, 

surface materials, elevation, expected runoff, and opportunity to install the slope breakers based on the ROW

configuration and topography, as well as experience. The permanent slope breakers will be installed in all areas 

except pastures and lawns. A typical design is provided in Attachment 1 (see Drawing 1408.34-X-0008). During

installation of permanent slope breakers, interceptor dikes or swales, as described in Runoff Controls 

(Section 3.1.4) above, will also be installed at appropriate locations, as directed by the EI or authorized 

representative (see Drawing 1408.34-X-0015).
SECTION 4

4-1

Nonstormwater Discharges

The main nonstormwater discharges associated with construction of the pipeline are trench dewatering and 

hydrostatic test water discharge. 

4.1 Trench Dewatering

During construction, trench dewatering may be required in areas of high groundwater. These areas are expected 

to be associated with floodplains, wetlands, or other areas where standing water is seasonally present. The 

construction schedule will coincide with the period when the soils in these areas are expected to be at their 

driest. 

All water associated with trench dewatering will be pumped to a discharge structure similar to Drawing 1408.34-

X-0013 in Attachment 1, which will be appropriately sized for the discharge volume. Discharge will occur in wellvegetated, gently sloping upland areas to promote infiltration. Water associated with trench dewatering will not 

be directly discharged to waterbodies.

4.2 Hydrostatic Testing

After backfilling, the pipeline will be hydrostatically tested in accordance with DOT regulations to ensure that the 

pipeline is capable of operating at design pressure. Should a leak or break occur, the pipeline will be repaired and 

retested until the specifications are achieved. Hydrostatic test water will be obtained from municipal and surface 

water sources.

Some of the hydrostatic test water will be discharged directly to waterbodies as identified in Revised Table 2.2-10 

of Revised Resource Report 2—Water Use and Quality The water discharge from these activities will be directed 

to a straw bale dewatering structure to dissipate energy to prevent erosion and to filter the discharge in order to

avoid sedimentation (see Drawings 1408.34-X-0012 and 1408.34-X-0013 in Attachment 1). Hydrostatic test water 

discharges to ground and surface water will occur through an appropriately sized discharge structure. The 

proposed hydrostatic test water discharge locations for the WEP will occur as shown on the alignment sheets in 

Revised Appendix 1C of Revised Resource Report 1—General Project Description and are listed in Revised 

Table 2.2-10 in Revised Resource Report 2—Water Use and Quality. 

Northwest’s EI will visually monitor the release of hydrostatic test water and trench dewatering activities to 

ensure that no erosion or sedimentation occurs. In addition, the EI will ensure that turbid water is not discharged 

to waters of the State. If the EI determines that a discharge is occurring, the receiving water will be visually 

monitored for turbidity. If turbidity is observed, the dewatering operations would be immediately adjusted/ 

reinstalled to ensure that the discharge to surface water is stopped and water quality standards are not exceeded.
SECTION 5

5-1

Restoration and Revegetation

Initial revegetation of disturbed areas will begin as soon as possible after construction. Waterbody crossings will 

be stabilized and temporary sediment barriers will be installed within 24 hours in accordance with FERC’s Wetland 

and Waterbody Procedures (Section V.C.2). Final grading and permanent erosion control measures will be 

completed within 20 days (10 days in residential areas) after the trench is backfilled, weather and soil conditions 

permitting. During final cleanup and initial revegetation, permanent repairs of fences, gates, drainage ditches, and 

other structures removed or damaged during construction will be completed.

Streambeds will be returned to their preconstruction condition, and stream banks will be restored and mitigated 

in-kind or to a greater functional quality than their preconstruction condition and revegetated, in accordance with 

FERC’s Wetland and Waterbody Procedures. Final cleanup will include regrading, mulching, placing erosion 

control mats, reseeding, and/or transplanting vegetation, as appropriate. Reseeding and revegetation will be 

accomplished as quickly as possible following pipe installation. If precipitation events or other complications 

preclude the completion of seeding and revegetation immediately following construction, exposed erodible 

substrates will be covered with straw or other suitable mulch until seeding is completed and seedlings are 

established as described below. New Attachment 2 contains a description of stream bank and streambed 

restoration methods. Northwest will work with individual landowners to address restoration of pastures and 

residential lawns, ornamental shrubs, and other landscaping. In residential areas, Northwest will use contractors 

familiar with local horticultural and lawn establishment procedures for revegetation work or will compensate 

landowners to restore these areas. Noxious weeds will not be introduced into the restored areas. The shrub 

containers will be inspected for signs of noxious weeds prior to planting in restoration areas. Specific revegetation 

procedures will be determined during easement negotiations with individual landowners.

Once site restoration is complete, as-built surveys and post-construction data for compliance and effectiveness 

monitoring will be collected (see Section 5.18, Monitoring and Maintenance).

5.1 Recontouring

All graded areas associated with pipeline construction will be regraded and contoured to blend into the 

surrounding landscape and to reestablish natural drainage patterns. Emphasis during recontouring will be to 

return the entire ROW to its approximate original contours, to stabilize slopes, to control surface drainage, and to 

provide a more aesthetic appearance. All surface water and stormwater runoff from the WEP will be discharged 

to a natural location and not be diverted in a manner that would create an adverse impact on downhill properties.

Ruts and other scars will be filled and all drainage ditches will be returned to their preconstruction condition. 

Recontouring to the original grade in disturbed wetlands is especially critical so that the wetland hydrology is not 

altered. Existing culverts that are damaged or removed during construction will be replaced to their original or 

better condition. No other culverts will be installed, except those permitted by the appropriate federal, state, 

and/or local agencies. 

At waterbodies, native materials will be backfilled in the top of the trench to ensure the existing channel condition 

is maintained. In-stream roughness elements, such as boulders and large wood, will be replaced in similar 

configurations to ensure that hydraulic roughness conditions are similar to preconstruction conditions. The 

original profiles and banks may be graded to a stable angle of repose to prevent erosion. Excess rock that cannot 

be returned to the trench or used for slope stabilization, and is not used as in-stream structure for habitat 

mitigation or enhancement, may be distributed throughout the ROW or be used as a barrier to block 

unauthorized vehicular access to the ROW. No solid waste or construction debris will be allowed to remain in the 

ROW after final grading.
5 RESTORATION AND REVEGETATION

5-2

5.2 Construction Debris Disposal

During final cleanup, all construction debris (e.g., timber, slash, mats, garbage, drilling fluids, excess rock) will be 

cleared from the ROW and disposed of in accordance with state and local regulations. Temporary erosion and 

sediment control measures will be removed and disposed of properly, and any sediment trapped by these 

measures will be removed or stabilized in such a manner that the trapped sediment does not reenter the stream 

system.

5.3 Soil Compaction

Northwest will test for soil compaction in residential areas, active agricultural fields, and pastures. Tests will be

conducted on the same soil type under similar moisture conditions as specified in Section V.C.1. in FERC’s Upland 

Plan. Pursuant to FERC’s Upland Plan, the EI will be responsible for conducting subsoil and topsoil compaction 

testing and determining corrective measures. Compaction will be relieved in residential areas based on sitespecific conditions.

Over-compacted soil will be scarified (where necessary, as determined by the EI) by ripping or chiseling to loosen 

soils compacted by equipment traffic prior to reseeding the ROW. Scarifying the subsoil will also promote water 

infiltration and improve soil aeration, root penetration, and revegetation success.

Where compaction is evident, and if deemed necessary, scarification will occur in disturbed areas, including the 

passing lane or TEWAs, even if these areas were only scalped of vegetation or driven over. Scarification will be at 

least 12 inches deep with rippers spaced not more than 16 inches apart unless approved by the EI. Ripping and 

chisel plowing will occur when materials are dry to promote the shattering of compacted layers.

In wetlands, scarification is not anticipated because traffic will be limited in these areas to that needed to clear 

the ROW, dig the trench, remove the 26-inch pipeline, fabricate and install the 36-inch pipeline, backfill the 

trench, and restore the ROW. Equipment mats will be used in wetlands where soils are saturated or where 

standing water is present to stabilize these areas and minimize compaction. The need for scarification in wetland 

areas will be determined by the EI. Scarification will not be conducted in wetlands where it may adversely affect 

the wetland hydrology.

5.4 Scarification

Prior to respreading the topsoil, the right-of-way will be scarified (where necessary as determined by the EI) by 

ripping or chiseling to loosen compacted areas from equipment traffic. Scarifying the subsoil will also promote 

water infiltration and improve soil aeration, root penetration, and revegetation success.

Where compaction is evident, and if deemed necessary, scarification will occur in disturbed areas, including the 

passing lane or TEWAs, even if these areas were only scalped of vegetation or driven over. Scarification will be at 

least 12 inches deep with rippers spaced not more than 16 inches apart, unless approved by the EI. Ripping and 

chisel plowing will also occur when materials are dry to promote the shattering of compacted layers.

In wetlands, scarification is not anticipated because traffic will be limited in these areas to that needed to clear 

the right-of-way, dig the trench, fabricate and install the 36-inch pipeline, backfill the trench, and restore the 

right-of-way. Equipment mats will be used in wetlands where soils are saturated or where standing water is 

present to stabilize these areas and minimize compaction. Therefore, the need for scarification in wetland areas 

will be determined by the EI. Scarification will not be conducted in wetlands where it may adversely affect the 

wetland hydrology.

5.5 Soil Replacement

All topsoil salvaged will be uniformly spread over the portions of the ROW from where the soil was salvaged. If 

compaction occurs during this operation that might not be relieved during seedbed preparation, all compacted 
5 RESTORATION AND REVEGETATION

5-3

areas will be scarified. Topsoil spreading will not occur during wet periods when soils are easily compacted and all 

travel over re-topsoiled areas will be restricted. 

5.6 Large Woody Debris Placement in Streambeds

If large woody debris (LWD) is removed from the streambed during construction, it will be stockpiled until 

construction is completed and then replaced. LWD placement will be done in accordance with the state of 

Washington Stream Habitat Restoration Guidelines (Cramer, 2012). The EI will be responsible for ensuring that the 

LWD is appropriately anchored to prevent it from displacing downstream and that post-construction placement 

will provide similar habitat benefits to preconstruction conditions. Large trees removed from the construction 

ROW will also be stockpiled for use in post-construction restoration operations.

5.7 Rock Removal

FERC’s Upland Plan requires the removal of excess rock from the top 12 inches of soil to the extent practicable in 

all rotated and permanent croplands, hayfields, pastures, residential areas, and other areas at the landowner’s 

request. In these areas, Northwest will clean up excess rock to a condition similar to adjacent portions of the 

construction ROW (e.g., size, density, and distribution of rock) unless the landowner and Northwest negotiate 

other requirements. The rock collected from these operations will either be hauled to an approved landfill or 

commercial quarry or will be disposed of in upland areas within the certified construction limits, with approval of 

the landowner. The use of alternate disposal locations will be approved by FERC.

5.8 Seedbed Preparation

Seedbed preparation will be conducted immediately prior to seeding to prepare a firm seedbed conducive to 

proper seed placement and moisture retention. Seedbed preparation will also be performed to break up surface 

crusts and to minimize annual weeds that may have developed between initial revegetation and seeding. Noxious 

weeds with perennial roots or rhizomes will be controlled before seeding or replanting.

A seedbed will be prepared in disturbed areas, where necessary, to a depth of 3 to 4 inches using appropriate 

equipment to provide a seedbed that is firm, yet rough. A rough seedbed is conducive to capturing or lodging 

seed when broadcast or hydroseeded, and it reduces runoff and erosion potential. The rough seedbed will retain 

soil moisture for seedling germination and establishment.

In most areas, final ROW cleanup procedures should be sufficient because it leaves a surface smooth enough to 

accommodate a drill seeder pulled by a farm tractor and rough enough to catch broadcast seed and trap moisture 

and runoff. However, additional preparation such as chisel plowing or disking may be necessary to prepare an 

adequate seedbed. Where residential lawns or landscaped areas are disturbed, more intensive ground and 

seedbed preparations may be required, including rock collection, grading, and soil preparation/amending.

5.9 Fertilization

Northwest will use a standard fertilization rate of 200 pounds per acre bulk triple-16 fertilizer (16:16:16 - nitrogen, 

potassium, and phosphorus), or a suitable site-specific fertilizer, on all disturbed areas to be reseeded, except in 

wetlands. This fertilization rate will apply 32 pounds per acre of elemental nitrogen, potassium, and phosphorus. 

The NRCS (2012) indicated that the proposed fertilization rate, which has been used on Northwest’s previous 

projects in western Washington, was acceptable for the WEP area. Where fertilizer is applied by broadcast 

methods, the fertilizer will be incorporated into the top 2 inches of soil. Where the fertilizer is applied by 

hydroseeding, the fertilizer will be applied with the hydroseeding slurry. The NRCS did not recommend the

addition of lime or other soil pH modifiers. 
5 RESTORATION AND REVEGETATION

5.10 Seed Mixtures and Supplemental Plantings

As required by FERC’s Upland Plan, Northwest has consulted with the NRCS (2012) regarding recommended seed 

mixtures for the WEP. The NRCS-recommended seed mixtures for the WEP are listed in Revised Table 5.10-1. The 

seed mixtures are based on bulk seeding rates and are not based on pure live seed. All seed will be tested for 

quantity of weed seed within 12 months of use. The seed will be free of noxious weeds and the quantity of total 

weed seed will be low. The EI will review all seed tags prior to use to ensure that these procedures are 

implemented. The NRCS-recommended seeding rates specified in Seed Mixtures 1, 2, 3, and 4 in Revised Table 

5.10-1 are based on broadcast seeding methods. If hydroseeding occurs, the broadcast seeding rate will be used

plus any adjustment the hydroseeding company recommends based on their equipment specifications. If drill 

seeding is conducted, the seeding rate could be divided in half. These mixtures have been used on Northwest’s 

previous projects in western Washington and have been approved by permitting agencies including U.S. Army 

Corps of Engineers and Washington Department of Ecology. Individual landowners may also specify seed mixtures 

for their properties, provided that these seed mixes do not contain noxious weed seeds. Residential landscaping is 

discussed in Section 5.15.

5.11 Seeding Timing

Disturbed areas will be seeded within six working days of final grading, weather and soil conditions permitting. It 

is expected that seeding of restored ROW areas may begin as early as mid-August and will proceed until about 

mid-September until all areas have been reseeded. According to the NRCS, seeding past October 10 will require 

mulching and may not germinate to provide an effective cover unless the weather is unseasonably warm. If 

seeding is not completed by mid-September, a temporary winter cover consisting of cereal rye or winter wheat at 
5 RESTORATION AND REVEGETATION

5-6

a bulk rate of 120 pounds per acre will be considered by the EI or Northwest’s authorized representative to 

ensure adequate erosion control (see Revised Table 5.10-1). Where a temporary winter cover is planted, it will be 

planted by mid-October and will be included with the permanent seed mixture.

5.12 Seeding Methods

Seeding will be conducted using either a seed drill or broadcast and hydroseeding according to the guidelines in 

FERC’s Upland Plan. Where broadcast seeding occurs, other than hydroseeding, the seeded area will be lightly 

dragged with chains or other appropriate harrows to lightly cover the seed. Fertilizer and mulch will not be used in 

wetlands.

5.13 Supplemental Wetland and Riparian Plantings

To mitigate impacts on riparian areas, Northwest will plant native shrubs and trees in areas where these species 

existed prior to construction or to enhance existing conditions where landowners allow. Table 5.13-1 provides a 

list of suggested native trees and shrubs that are common in the WEP area in these habitats and which would be 

planted after final restoration and cleanup during appropriate planting periods (during the winter and early 

spring). To complete these restoration plantings, Northwest will select a restoration contractor who is

knowledgeable about local wetland and riparian ecosystems and the species’ characteristics and site growth 

requirements, and who is able to inspect the source of the plantings for indications of noxious weeds, where 

feasible. The shrubs and trees planted at each site will be determined at the time of planting based on the 

moisture regimes and site-specific conditions at each planting location and based on the plant spacing provided in

Table 5.13-1.

a Planting stock sizes may include bare root equivalents.

b Shrubs will be installed in clusters of 5 to 10, while trees will be individual specimens.

Disturbed riparian areas will be replanted with trees and shrubs according to FERC’s Wetland and Waterbody 

Procedures (Sections V.C.6. and V.D.1). Shrubs will be planted and allowed to grow within 5 feet of the pipeline 

centerline. Trees will not be planted within 15 feet of either side of the pipeline centerline to facilitate corrosion 

and leak surveys and to prevent roots from damaging pipe coatings. In riparian areas, shrubs and trees will be 

planted across the ROW for a width of 25 feet from the waterbody banks subject to the existing land uses and 

landowner approval.

5.14 Mulch 

Mulch will be applied on all slopes where necessary to stabilize the soil. The mulch will be uniformly applied at a 

rate of 2 tons per acre to cover at least 75 percent of the ground surface. If seeding occurs after October 10, all 

disturbed areas will be mulched. Mulching will occur during seeding (where hydroseeded) or immediately after 

seeding where broadcast or drill seeding occurs. All straw used for mulch will be weed-free. Anchoring straw 

mulch by crimping the mulch in is not expected to be necessary because strong winds, which could dislodge the 

mulch, typically occur during the winter rainy season when the moist conditions will bind the straw to the soils; 

however, the EI will determine if straw crimping is appropriate.

5.15 Residential Landscaping

In residential areas, Northwest will initiate cleanup operations within 10 days after backfilling the trench, 

consistent with FERC’s Upland Plan (Section V.A.1), or pursuant landowner construction stipulations. This includes 

final grading, topsoil replacement, and installation of permanent erosion control structures. Residential 

landscaping will be restored by a landscaping contractor familiar with local conditions. Landscaping may include 

lawns, shrubs, trees, fences, irrigation systems, and other landscape features as agreed to during Northwest’s 

easement negotiations. Noxious weeds and aggressive ground cover plants, such as English ivy, holly, and similar 

plants, will not be used.

5.16 Grazing Deferments

Northwest will develop grazing deferment plans, where necessary, based on negotiations with individual 

landowners. Grazing deferment plans may include temporary fencing to keep horses or livestock off of the 

restored ROW, boarding animals at alternate locations, purchasing supplemental feed, or other similar methods 

to minimize potential livestock disturbance to ROW revegetation efforts. Grazing deferments will be negotiated 

with livestock owners during the easement process. 

5.17 Noxious Weeds

The NRCS (2012) was consulted for recommendations to prevent the introduction or spread of noxious weeds and 

soil pests. The NRCS has recommended that the best way to control the establishment of invasive species is to 
5 RESTORATION AND REVEGETATION

5-8

plant desirable vegetation at relatively high rates so they provide vigorous competition. In addition, Northwest 

will include the following measures to ensure that the potential spread of noxious weeds is minimized: 

• Prior to transport to the construction ROW, all equipment will be cleaned and inspected to ensure it is free of

potential weed seeds or sources (i.e., soil, roots, or rhizomes). In addition, all equipment will be inspected and

cleaned when leaving the ROW after construction to verify that it is free of potential weed seeds or sources.

The EI or Northwest’s authorized representative will be responsible for inspection of all equipment and trucks

used on the WEP to ensure they are clean.

• Certified weed-free straw will be used for mulch and sediment barriers, dewatering structures, or other uses

along the ROW. The EI or Northwest’s authorized representative will be responsible to ensure that all straw

hauled to the construction yard will be certified weed-free. The Washington State Department of Agriculture

Plant Services Program has a weed-free hay and mulch program (Washington Department of Agriculture,

2013) and maintains a list of producers of certified hay and mulch.

• Prior to clearing, the WEP will be surveyed for areas that may be infested with priority noxious weeds that are

listed in the specific county’s priority noxious weed list and that require control. The results of these surveys

will be provided to the specific county’s Noxious Weed Control Board. Surveys will be conducted by

Northwest’s EI or authorized representative in consultation with the applicable county’s Noxious Weed

Control Board. Northwest’s EI or authorized representative will have expertise in identifying noxious weeds

and will be able to provide prevention training and appropriate invasive plant identification resources to

contractors prior to beginning construction. Infested areas will be controlled in a manner consisted with

RCW 17.10 prior to clearing. Identified noxious weed infestations will be cleared using standard best

management practices as prescribed by the local county Noxious Weed Control Board and using methods that

minimize transport of weed seeds, roots, and rhizomes or other vegetative materials and soil from the site

along the construction ROW.

• Before stockpiling cleared vegetation and salvaging topsoil in areas where infestations have been identified or

noted in the field, the contractor will control the noxious weed infestations as practicable to reduce the

transport of soil-born noxious weed seeds, roots, or rhizomes. If noxious weed seeds or other propagative

parts, such as rhizomes, are mixed in with other cleared vegetation, the material will not be transported

offsite unless it is contained and disposed of an appropriate sanitary landfill.

• During revegetation, the contractor will return topsoil and vegetative material from infestation sites to the

areas from which they were stripped. Any clearing equipment used in areas of county-listed weeds will be

cleaned by hand or blown down with air prior to leaving the sites. Where possible, equipment will be rinsed

off onsite, within a contained area. Infested areas will be mapped to ensure that these areas will be

monitored during operations so that the weeds will be controlled and not spread.

• Where weed control is necessary, Northwest will employ mechanical methods (mowing, disking) to prevent

the spread of these weeds or will employ a licensed contractor to ensure that the appropriate herbicides are

used for the targeted weed species during the proper phenological period at the specified rate. Northwest will

work with landowners and the county Noxious Weed Control Board to remove identified noxious weed

communities in a manner that is consistent with the county’s recommended practices and the landowner’s

preference, consistent with 18 CFR Part 380.15(e)(3). Methods likely to be employed include mechanical

means, biological controls, and species-specific application of herbicides (with landowner approval).

• Weed control measures will conform with the requirements outlined in RCW 17.10 and Washington

Administrative Code 16-750. The contractor will ensure that the herbicides are used according to the labeling

restrictions and according to all applicable laws and restrictions. The contractor will confirm that the

herbicides are used under the proper seasonal and weather conditions to ensure the herbicides’ effectiveness

and to minimize drift to nontargeted areas. Herbicides will not be applied during precipitation events or when

precipitation is expected within 24 hours or as specified on the label. Herbicides will not be used within

100 feet of a wetland or waterbody unless allowed by the appropriate agency. Prior to herbicide application,

Northwest and/or its contractor will obtain all required permits from the local jurisdictions/authorities.
5 RESTORATION AND REVEGETATION

5-9

Northwest will use invasive species BMPs suggested by the appropriate county Noxious Weed Control Board. 

5.18 Monitoring and Maintenance

Northwest will test, operate, and maintain the proposed WEP facilities in accordance with 49 CFR Part 192 and 

other applicable federal and state regulations. The pipeline ROW will be clearly marked where it crosses public

roads, railroads, rivers, fenced property lines, and other locations as necessary. All pipeline facilities will be 

marked and identified in accordance with applicable regulations to avoid accidental excavation.

Routine vegetation maintenance (mowing and selective herbicide treatments) will not occur more frequently than 

every 3 years. However, to facilitate periodic corrosion and leak surveys, a corridor not exceeding 10 feet in width 

centered on the pipeline may be maintained annually in an herbaceous state. Northwest will not conduct 

vegetation maintenance over the full width of the permanent ROW in wetlands and waterbody riparian areas. 

Vegetation maintenance adjacent to waterbodies will allow a riparian strip at least 25 feet wide, as measured 

from the mean high water mark of the waterbody, to permanently revegetate with native plant species across the 

entire construction ROW if permitted by the landowner.

5.18.1 Upland Areas

Northwest will conduct follow-up inspections of all disturbed areas after the first and second growing seasons to 

determine the success of revegetation. Revegetation will be considered successful in upland areas if upon visual 

survey the density and cover of non-nuisance vegetation are similar in density and cover to adjacent undisturbed 

lands, and noxious weeds are not present. If vegetative cover and density are not similar or there are excessive 

weeds after two full growing seasons, a professional agronomist or equally qualified professional shall determine 

the need for additional restoration measures. Northwest will continue revegetation efforts until revegetation is 

successful. Northwest will control noxious weeds regulated under RCW 17.10 that occur in the ROW until the site 

has been stabilized. Repair of erosion control structures will occur until the ROW has successfully revegetated and 

has stabilized. Once the site is stabilized, temporary erosion control measures will be removed.

5.18.2 Waterbodies and Wetlands

Post-construction monitoring will be conducted twice during the first year following construction at 

approximately 6-month intervals and annually thereafter for a total of 3 years or until successful revegetation is 

complete, whichever is longer.

Every attempt will be made to assess streams at the same time of year as their preconstruction site visit. The 

post-construction monitoring will focus on identifying problems with bank stabilization and revegetation.

During post-construction monitoring events, Northwest or a contractor will look for trench subsidence and 

erosion indicators such as gullies, undercutting banks, bare ground, bank slumping, and evidence of sheet erosion. 

If initial erosion control features are shown to be inadequate or if erosion control structures fail, Northwest will 

retain a contractor to conduct remedial actions as soon as site conditions allow. Repairs or remedial actions could 

include additional seeding or transplanting, installing more robust erosion/sediment control materials, 

maintaining or replacing the initial erosion control features, placing boulders or LWD, slope armoring, additional 

mulching, or matting. If trench subsidence is observed, Northwest will direct the contractor to fill and compact the 

trench to grade with appropriately sized substrate. If trench remediation is required below the ordinary high 

water mark, all activities will be conducted within authorized WDFW in-water work periods.

Revegetation monitoring will include a qualitative assessment of the following parameters in comparison to 

adjacent undisturbed areas:

• Percentage of total adjacent herbaceous cover (seeded/transplanted species plus desirable volunteers)

• New or expanded populations of noxious weeds

• Species composition

Post-construction surveys will be conducted by experienced biologists.
5 RESTORATION AND REVEGETATION

5-10

5.18.2.1 Success Criteria

A criterion for establishing adequate vegetation recruitment will be defined in the final Construction, Restoration, 

and Monitoring Plan following consultation with WDFW and DNR. For example, areas may be considered 

successfully reestablished if, after the first year, disturbed areas contain at least 50 percent of the herbaceous 

cover of adjacent undisturbed areas, with no bare spots greater than 2 feet in any dimension, and the species 

composition is a mixture of seeded/replanted species and desirable volunteers. At the end of 3 years, success may 

be defined as at least 80 percent of the herbaceous cover of adjacent undisturbed areas.

Areas with poor reestablishment or undesirable species mixes will be evaluated to determine, if possible, the 

cause of the problem (that is, poor germination, poor planting technique, herbivory), and corrective measures will 

be undertaken. Potential corrective measures include replanting, planting an alternative species mix, or 

protecting existing seedling from herbivory. Northwest will control any noxious weeds regulated under RCW 17.10 

until the revegetation is successful.

The reclaimed ROW will be considered stable when the surface appears similar to adjacent undisturbed land and 

the following accelerated erosion indicators do not exist:

• Perceptible soil movement (exceeding preconstruction conditions)

• Flow pattern development resulting in rills or gullies greater than 3 inches deep

• Evidence of sheet erosion

• Evidence of siltation in stream substrates downstream of the crossing

• Perceptible downstream movement of in-stream rock or woody debris

• Trench subsidence or slumping

5.18.2.2 Reporting

Following each monitoring period (twice during the first year and annually thereafter), Northwest will prepare a 

report for submittal to the appropriate agencies. The report will contain the following:

• Summary of bank vegetation recruitment and species composition as compared with adjacent undisturbed

areas

• Assessment of the condition of transplants in riparian areas

• Discussion of non-native species/noxious weeds in disturbed areas

• Description of any deviations from the monitoring plan

• Discussion of revegetation performance and an assessment of whether revegetation goals are being met

• Any observations not included on monitoring forms that further elucidate the success or potential for failure

of revegetation/restoration efforts

• Identification of areas that require remedial action

• Recommendations and schedule for remedial action(s)

• Before/after photo pairs for each crossing

• Monitoring forms

5.18.2.3 Adaptive Management Contingency Plan

Relative to stream crossings, adaptive management will focus on several areas: (1) post-construction 

rehabilitation of stream banks; (2) monitoring slope stability and landslides; and (3) monitoring changes in stream 

geomorphology that have potential to expose the pipeline and have an effect on fluvial processes. Each area has 

independent time horizons. For example, expectations for rehabilitation fall within a timeframe of 3 years in 

which successful establishment can be measured and determined to be adequate. Slope and landslide risks are 

events that are monitored periodically, and continuously during the rainy season when soils are saturated. 

Depending on gradient, soils, and substrate, mass movements may be measured in terms of strains or 
5 RESTORATION AND REVEGETATION

5-11

imperceptible movements from year to year, which can be followed by a sudden catastrophic event. Fluvial 

processes that result in vertical scour or channel migration are typically events, under normal circumstances, that 

occur over periods of decades to centuries and therefore may extend beyond the design life of the project.

Rehabilitation of Stream Banks. The purpose of semiannual to annual post-construction monitoring is to 

determine the success of plantings and stability of bioengineered bank restoration. At any point during the 

designated monitoring period, typically 5 to 10 years, corrective actions may be required if survival rates and plant 

cover are inadequate or if bank stabilization methods failed. Northwest will assess potential reasons for subpar 

performance or stabilization failure by evaluating a number of issues, including but not limited to the following: 

species composition, appropriateness of time of year of plant installation, quality of materials, causes of plant 

mortality, and whether bank or stream restoration procedures were properly engineered and installed. Adaptive 

management will be designed to address the specific reasons for subpar performance or stabilization failures. This 

may require substitute plant material, replanting, repairs, regrading, or reinstallation of stabilization structures.

In wetland areas, revegetation will be considered successful if the cover of herbaceous and/or woody species is at 

least 80 percent of the type, density, and distribution of the vegetation in adjacent wetland areas that were not 

disturbed by construction. If revegetation is not successful at the end of 3 years, Northwest will develop and 

implement (in consultation with a professional wetland ecologist) a remedial revegetation plan to actively 

revegetate the wetland and will continue revegetation efforts until wetland revegetation is successful. Northwest 

will control any noxious weeds regulated under RCW 17.10 until the re-vegetation is successful. 

Routine vegetation maintenance (mowing and selective herbicide treatments) shall not be done more frequently 

than every 3 years. However, to facilitate periodic corrosion and leak surveys, a corridor not exceeding 10 feet in 

width centered on the pipeline may be maintained annually in an herbaceous state. Northwest will not conduct 

vegetation maintenance over the full width of the permanent ROW in wetlands and waterbody riparian areas. 

Vegetation maintenance adjacent to waterbodies will allow a riparian strip at least 25 feet wide, as measured 

from the mean high water mark of the waterbody, to permanently revegetate with native plant species across the 

entire construction ROW if permitted by the landowner.

5.18.3 Data Storage and Analysis

Data collected during field reconnaissance, preconstruction, and post-construction surveys will be collected in log 

books, on field maps, on data sheets, in photographs, and in electronic form. The data will be put through quality 

control procedures every evening after data collection by the field biologists who collected the data and in the 

office after field downloads. Monitoring data will be stored and maintained by Northwest or its contractor. Data 

will be entered into geographic information system (GIS) or other standard database(s) for use and storage and 

will be made available to agencies within 30 days of a request. Data tables will be normalized to ensure consistent 

data formats among survey events. Where appropriate, data will be stored as attribute tables associated with GIS, 

either as part of shape files or as geodatabases. Selected datasets will be made available via File Transfer Protocol 

or other Web-based protocols.

Following each monitoring period (twice during the first year and annually thereafter) for a total of 3 years or until 

successful revegetation is complete, whichever is longer, Northwest will prepare a report for submittal to WDFW 

and other appropriate agencies. The report will contain the following components:

• Summary of bank vegetation recruitment and species composition as compared with adjacent undisturbed

areas

• Assessment of the condition of transplants in riparian areas

• Discussion of non-native species/noxious weeds in disturbed areas

• Tabular and graphical summaries of results

• Description of any deviations from the monitoring plan

• Discussion of restoration performance and assessment of whether restoration goals are being met
5 RESTORATION AND REVEGETATION

5-12

• Any observations not included on monitoring forms that further elucidate the success or potential for failure

of revegetation/restoration efforts

• Identification of areas that require remedial action

• Recommendations and schedule for remedial action(s)

• Before/after photo pairs for each waterbody crossing

• Monitoring forms

Northwest will contact the agencies immediately if there is a loss of fish passage or if dead fish are observed.

These reports will be submitted to WDFW and other appropriate agencies for a minimum of 30 days for review 

and comment. After the 30-day review period, Northwest will meet with the agencies if necessary to discuss any 

comments, recommendations, and future actions at the sites. If actions are required at any site, Northwest will 

prepare a plan of action for that year, with a 30-day minimum review. Upon agency approval, Northwest will 

implement the plan of action.

5.18.4 Monitoring Quality Assurance Plan

To ensure the quality of the monitoring program, Northwest will implement quality assurance and quality control

procedures and apply them to the following aspects of the monitoring plan:

• Data collection

• Data storage

• Data analysis and reporting

The Northwest monitoring program manager will be responsible for quality assurance. Northwest will be 

responsible for ensuring that data collected within various disciplines meet professional standards and comply 

with appropriate methodologies and protocols. Where data must be integrated either for analysis or reporting, 

Northwest will develop consistent procedures. The following items will be addressed:

• Exact location and documentation of monitoring locations

• Training of individuals collecting data

• Documentation and records management regarding how field data are recorded, including development of

standardized monitoring forms

• Data review, validation, and verification requirements (e.g., cross-checking field data sheets, looking for data

gaps, checking calculations, looking for outliers)

• Data management protocols

• Reporting procedures

ATTACHMENT 2

Stream Bank and Streambed Restoration Methods 

Vegetation Alone Vegetation is established on bare soils to help 

prevent surficial erosion, minimize shallow seated mass movement, provide habitat, and enhance aesthetics or visual appearance. 

Live Staking Live staking is used for revegetation, soil 

reinforcement, and anchoring erosion control materials. Willow cuttings are typically 1.5 to 3.3 feet long, 2/3 inserted in the ground. The portion of the stem in the soil will grow roots and the exposed portion will develop into a bushy riparian plant. 

Erosion Control Blankets 

Erosion control blankets are temporary, rolled products consisting of flexible nets or mats manufactured from natural materials, usually straw, wood, excelsior, or coconut. Various grades of biodegradable fibers and netting are available.
ATTACHMENT 2

Stream Bank and Streambed Restoration Methods 

Rootwad Revetments 

Rootwad revetments are interlocking tree materials that are continuous and resistive. The materials are designed to resist erosive flows, usually on the outer bank of a meander bend when habitat diversity is desirable and woody materials are available. 

Live Gully Fill Repair

Live gully fill repair consists of alternating layers of live branch cuttings and compacted soil. This reinforced fill can be used to stabilize trench backfill and is suitable for filling and repairing elongated voids in a slope. 
ATTACHMENT 2

Stream Bank and Streambed Restoration Methods 

Turf Reinforcement Mats 

Turf reinforcement mats (TRMs) are long lasting and designed to resist shear and tractive forces. They are specified for banks subjected to flowing water. Mats are ultraviolet fibers in a threedimensional matrix. TRMs work with plant roots and shoots to be mutually reinforcing. The mats are best suited for low-energy systems with natural herbaceous riparian areas. Native grasses are used. 

Vegetated Geogrids

Vegetated geogrids are used to quickly establish riparian vegetation. Geogrids can be installed on a steeper and higher slope and have a higher initial tolerance of flow velocity than brush layering. The grid produces a newly constructed, well-reinforced streambank. This method is useful in restoring outside bends where erosion is a problem. The geogrid captures sediment and enhances conditions for colonization of native species. Slope stability analyses are recommended. The geogrid can be used to retain fines. 

Engineered Log Structure 

Engineered log structures provide protection to the streambank in areas with near vertical banks where bank sloping options are limited. The structure creates a natural appearance, provides immediate protection, and accelerates the establishment of woody species. Effective on outside of bends of streams where high velocities are present. Appropriate (1) at the base of a slope where a low wall might be required to stabilize the toe and reduce slope steepness, and (2) above and below water levels where stable streambeds exist. 
ATTACHMENT 2

Stream Bank and Streambed Restoration Methods 

Constructed Riffles

Pools and riffles are common features found in natural or lightly altered streams. Constructed riffles, such as Newbury Riffles, are intended to replace pool and riffle habitat lost due to channelization or other types of stream alterations. The riffles provide benthic habitat and contribute to bed stability. Although the coarse material that comprises constructed riffles is not intended to be mobile during higher flows like natural riffle material, correctly-designed structures function similar to natural features. 

Slope Flattening Slope flattening is most successful on 

streambanks where moderate erosion and channel migration are anticipated. Reinforcement at the toe of the embankment is often needed. Used in conjunction with other protective practices where flow velocities exceed the tolerance range for available plants, and where erosion occurs below base flows. Slope stability analyses are recommended.

Unanticipated Discovery of Contamination Plan

The intent of this Unanticipated Discovery of Contamination Plan is to outline practices to employ in the event of 

an unanticipated discovery of contamination in soil, groundwater, and sediment when excavating during 

construction and/or maintenance activities, as well as debris or waste materials deposited on the pipeline rightof-way at Northwest Pipeline GP (Northwest) facilities. The purposes of this plan are to:

• Protect human health and worker safety;

• Prevent the spread of contamination; and

• Comply with applicable state and/or federal regulations.

1.0 Pre-Job Planning

When planning a project at Northwest facilities and/or along the pipeline right-of-way (ROW), the Chief Inspector 

(CI), Environmental Inspector (EI), District Manager, and/or their designees shall complete a review of the 

proposed pipeline and/or aboveground facility locations prior to the construction and/or maintenance activity in 

order to assess the potential for the presence of known or potential contamination. An assessment should also be 

made of the likelihood of encountering contamination during an excavation or along the surface. The scope of the 

review and assessment will depend upon the size of the project, past experience, and available information.

For pipeline construction projects, the review and assessment will consist of a site reconnaissance of the 

proposed work area, interviews with property owners, and a review of any readily available information. It may 

also be necessary to consult with the Environmental Permits and Natural Resources and/or Environmental 

Compliance Departments to conduct an environmental database search (e.g., Environmental Data Resources 

[EDR] search) and/or perform additional investigation. Generally, it is not anticipated that this review will identify 

contamination along the ROW, but it will likely identify areas where there is a higher potential for contamination.

For maintenance-related excavations at compressor and meter stations, these have a higher likelihood of 

encountering something unexpected due to the age of these facilities as well as the use of regulated substances at 

these facilities.

If it is determined that there is a high likelihood that the planned work will be conducted in close proximity to, or 

within, known or suspected contaminated sites, the Environmental Permits and Natural Resources and 

Environmental Compliance Departments should be consulted.

The results of this search/investigation will be reviewed prior to start of construction and/or maintenance activity 

and any identified contaminated sites and/or areas will be located and available information reviewed for 

potential impacts. In the event the planned work will impact a confirmed contaminated site, the Environmental 

Compliance Department will work with the appropriate regulatory agency, property owner, and responsible party 

to ensure the construction and/or maintenance activities are conducted in accordance with applicable and 

established site requirements. Where feasible, a re-route or other modification to the project should be 

considered. Postponement of the project may also be necessary.

If contaminated sites are identified for areas of the project, a list of the sites should be kept along with how the 

determination was made (EDR, property owner, agency report, etc.). An example of this list is included in 

Worksheet A in Attachment 1.

2.0 Unanticipated Discovery Response

In the event unanticipated contaminated soil, groundwater, or other potential environmental contamination is

encountered during the project (e.g., malodorous soils and/or groundwater with visible staining and/or sheen), 

the following general procedures will be implemented:
UNANTICIPATED DISCOVERY OF CONTAMINATION PLAN

2

1. All construction and/or maintenance work in the immediate vicinity of areas where suspected contamination 

or unknown wastes are encountered will be halted.

2. All construction, oversight, and observing personnel will be evacuated to a road or other accessible up-wind 

location until the types and levels of potential contamination can be verified by qualified personnel. This 

assessment may include, but not be limited to: observation by a qualified health and safety professional, field 

screening using the appropriate air sampling devices, and/or laboratory analysis of suspect material.

3. The CI, EI, and/or District Manager will be notified and they will consult with the company’s Environmental 

Compliance Department. The contacts for the Environmental Compliance Department will be provided prior 

to construction.

4. Following consultation with onsite personnel, the Environmental Compliance Department will be responsible 

for designating follow-up actions, including mobilizing emergency response personnel and coordinating with 

the U.S. Environmental Protection Agency (EPA) and/or state and local agencies as appropriate.

5. If an immediate or imminent threat to human health or the environment exists, the EI, CI, District Manager, 

and/or their designee will immediately contact the appropriate responding agency. For construction projects, 

the contact numbers for fire, police, and the state environmental hotline can be found on the Environmental 

Contacts List for the project.

6. If an immediate or imminent threat to human health or the environment does not exist, or has been abated, a 

determination will be made, after consulting with all responsible parties, whether any remedial action is 

necessary. If the company or its qualified contractor personnel is responsible for any remedial action, it will be 

limited to the planned work area only and no additional disturbance should be made except as needed to 

facilitate construction and/or maintenance activities.

− Representative samples of the suspected contaminated media (i.e., soil, water, and waste) may need to 

be submitted for laboratory analysis to determine waste classification and/or agency notification 

requirements, which can vary from state-to-state.

− The CI, EI, District Manager, and/or their designee shall consult with the Environmental Compliance 

Department for the appropriate analyses, sampling methodology, and sampling frequency.

− Any excavated soils or waste that are suspected of containing contamination above the appropriate 

cleanup standard, or otherwise regulated for disposal, will be placed on plastic sheeting and covered at 

the end of each work day or placed in an appropriate container to prevent the spread of contamination.

Containers must be closed or covered and any storage areas cordoned off with orange safety fence. All 

containers should be clearly labeled with the name of the contents and any known hazard associated with 

the material identified on the container. Known hazardous wastes should be labeled with the words 

“Hazardous Waste” and the date the waste was placed in the container.

− Water or groundwater suspected of being contaminated will not be discharged to grade without prior 

state approval. Options such as onsite storage tanks or discharge to a publicly owned treatment works 

should be considered. Limiting and/or diverting the flow of clean surface water away from the affected 

area, as well as other measures, may be implemented to minimize impacts and exposure to the work 

area.

7. If it is determined that the company or its qualified contractor will be responsible for arranging for disposal of 

any affected media (soil, water, waste), the material will be characterized and disposed of properly at a 

permitted facility in a timely manner. All disposal documentation should be obtained and filed in the project 

files and copies sent to the Environmental Compliance Department.

− If EPA-regulated hazardous wastes, Toxic Substances Control Act wastes, or state hazardous wastes are 

generated, an EPA generator identification number will need to be obtained. The Environmental 

Compliance Department must be contacted to assist in either obtaining a project-specific identification 

number or providing an EPA identification number for an existing facility.

SECTION 1

Introduction 

This Water Quality Monitoring Plan addresses the requirements for water quality monitoring associated with

construction of Northwest Pipeline GP’s (Northwest’s) Washington Expansion Project (WEP). This Plan addresses

monitoring requirements associated with construction stormwater runoff and pipeline trench dewatering

activities, waterbody crossings, and hydrostatic test water release. The Plan sets forth the monitoring procedures

as well as reporting and record‐keeping requirements. 

2-1 

SECTION 2

Purpose 

The purpose of this Plan is to set forth procedures for water quality monitoring that will be followed by Northwest

and its contractor during construction of the WEP.

3-1 

SECTION 3

Responsibilities 

Northwest is responsible for ensuring that all Northwest and contractor personnel associated with construction of

the WEP are familiar with the requirements set forth in the Section 401 Water Quality Certification and the

National Pollutant Discharge Elimination System Construction Stormwater General Permit as well as the

procedures set forth in this Plan. The contractor is responsible for carrying out the procedures set forth in this

Plan as directed by Northwest.

4-1 

SECTION 4

Construction Stormwater and Trench Dewatering 

Discharges 

4.1 Monitoring and Sampling 

Potential discharges to receiving waters that may occur during construction include stormwater runoff and water

from trench dewatering. It is not possible, prior to construction, to determine the locations for trench dewatering

because it will depend on conditions in the field at the time of construction (such as seasonal groundwater levels)

and the need for dewatering to access the trench. However, if it is determined that there is a discharge occurring

either to surface water or groundwater, water quality monitoring will be initiated according to this Plan.

A discharge to surface water or wetlands would occur if it is observed that stormwater or water from trench

dewatering is channeling and reaching surface water or wetlands. The potential outfalls for a discharge to surface

water have been defined as the waterbodies that will be crossed by the proposed pipeline, which are listed in

Attachment 1. If it is determined that there is a discharge to surface water or wetlands, weekly monitoring for the

following parameters shall be initiated:

 Turbidity. If stormwater or water from dewatering is discharged to surface water or wetlands, monitoring (a

grab sample) shall be conducted for turbidity at the receiving water and at the point of discharge. In the

receiving water, monitoring shall be conducted both upstream and downstream of the discharge point. The

effluent limitation for turbidity is 25 nephelometric turbidity units (NTU) at the point where stormwater is

discharged from the site or nor more than 5 NTU over background turbidity when the background turbidity is

50 NTU or less, and shall not have more than a 10 percent increase in turbidity when the background turbidity

is more than 50 NTU.

 Total petroleum hydrocarbons (TPH). If stormwater or water from dewatering is discharged to surface water

or wetlands and there is a visible sheen on the water, monitoring (a grab sample) shall be conducted for TPH

at the point of discharge and in the receiving water. If there is no visible sheen, monitoring for TPH is not

required. The maximum daily TPH effluent limitation for discharges to surface water is 5 milligrams per liter

and no visible sheen at any time.  

 pH. Monitoring for pH is required if engineered soils (i.e., concrete soil mixtures) are used and for the

discharge of hydrostatic test water. Monitoring (a grab sample) shall be conducted for pH on a weekly basis at

the point of discharge. The effluent limitation for pH is in the range of 6.5 to 8.5 standard units. It is assumed

pH sampling will not be necessary except at potential open‐cut road crossings where concrete soil mixture

backfill may be used.

4.2 Reporting 

The first monitoring period begins on the effective date of the permit. Monitoring results shall be submitted to

Washington Department of Ecology (Ecology) monthly. Monitoring data obtained during each monitoring period

shall be summarized, reported, and submitted on the discharge monitoring report (DMR) forms through Ecology’s

Water Quality Web Permitting Portal (WQWebPortal). DMR forms shall be received by Ecology no later than the

15th day of the month following the completed monitoring period. The DMRs shall be sent to:

DMRs must be submitted monthly whether or not the WEP was discharging. If there was no discharge during a

given monitoring period, Northwest will submit the form as required, with the words “No discharge” entered in

the place of monitoring results. For outfalls that had discharges during a given monitoring period, detailed DMR

forms for each associated discharging outfall must be submitted.

4.3 Records Retention 

The records of all monitoring information (site log book, inspection reports/checklists, etc.), this Water Quality

Monitoring Plan, the WEP Stormwater Pollution Prevention Plan, and any other documentation of compliance

with permit requirements will be retained during the life of the construction project and for a minimum of 3 years

following the termination of permit coverage in accordance with permit condition S5.C of the Construction

Stormwater General Permit.

4.4 Recording of Results 

For each measurement or sample taken, Northwest shall record the following information:

 Date, exact place, method, and time of sampling or measurement

 Individual who performed the sampling or measurement

 Dates the analyses were performed

 Individual who performed the analyses

 Analytical techniques or methods used

 Results of analyses

4.5 Noncompliance Notification 

If Northwest is unable to comply with any of the terms and conditions of the National Pollutant Discharge

Elimination System permit, the following steps shall be taken:

 Immediately take action to stop, contain, and clean up unauthorized discharges or otherwise stop the

noncompliance, correct the problem, and, if applicable, immediately repeat sampling and analysis of the

noncompliant activity.

 Immediately notify Ecology of the failure to comply. After immediate notification, Northwest shall submit a

detailed, written noncompliance report to Ecology within 5 days after becoming aware of the violation. The

report shall contain a description of the noncompliance, including exact dates and times, and if the

noncompliance has not been corrected, the anticipated time it is expected to continue, and the steps taken or

planned to reduce, eliminate, and prevent recurrence of the noncompliance.

 Northwest shall document the follow‐up monitoring triggered by noncompliance. Frequency of follow‐up

monitoring is once per day for each violated parameter until three consecutive daily samples show the

discharge(s) is back in compliance. These monitoring results shall be reported on the monthly DMRs.

4.6 Laboratory Analyses 

Prior to construction, Northwest will select a laboratory properly certified with the State of Washington to

perform analyses of water quality samples.

If it is determined that sampling for TPH is necessary (as determined by a visible sheen on the water), bottles

provided by the laboratory must be used to collect the samples. A supply of bottles should be obtained from the

laboratory and kept onsite so that they are readily available if it is determined that sampling for TPH must be

conducted. Chain‐of‐custody forms will be supplied by the laboratory and must be used. The sample bottles may

have preservative in them and care should taken to not spill the preservative when collecting the sample. Once

the sample is collected, it should be driven or shipped overnight to the laboratory.

SECTION 5

Waterbody Crossings 

5.1 Crossing Methods 

The WEP crosses many waterbodies, which vary in class. Intermittent waterbodies will be crossed within the

Washington Department of Fish and Wildlife‐recommended window for using flume or dam‐and‐pump methods if

water is present at the time of construction. Waterbodies that are dry at the time of construction will be crossed

by open‐cut methods.

5.2 Monitoring and Sampling 

During in‐water construction, visual monitoring (inspections) of both the work area and the areas upstream and

downstream of the work area will be conducted during and periodically between sampling efforts for turbidity.

Inspections of these areas will occur during work activity and hourly throughout all in‐water construction activity.

Samples for turbidity will be collected at each in‐water construction location, including all waterbodies crossed by

trenching with use of a flume or dam‐and‐pump methods. Sampling will occur every 2 hours throughout the first

day of in‐water construction activity at each location of such work. Subsequent sampling is dependent upon

monitoring results, but will be a minimum of three times per day during in‐water activity if no exceedances are

detected. Sampling and visual monitoring will increase if turbidity exceedances are observed or measured to be

above the temporary mixing zone criteria provided below.

For waterbodies flowing 10 cubic feet per second (cfs) or less at the time of construction (small waterbodies), the

point of compliance will be 100 feet downstream of the in‐stream activities. Samples will be taken at the following

locations:

1. At a site just upstream of the work area to determine background water quality

2. At a site half the distance (50 feet downstream) between the activity and the point of compliance (100 feet

downstream) to provide a margin of safety to protect water quality

3. At the point of compliance 100 feet downstream of the in‐stream activities  

For waterbodies flowing between 10 cfs and 100 cfs at the time of construction (medium‐sized waterbodies), the

point of compliance will be 200 feet downstream of the in‐stream activities. Samples will be taken at the following

locations:

1. At a site just upstream of the work area to determine background water quality

2. At a site half the distance (100 feet downstream) between the activity and the point of compliance (200 feet

downstream) to provide a margin of safety to protect water quality

3. At the point of compliance 200 feet downstream of the in‐stream activities

For sampling sites that must deviate from those designated above, Northwest will identify the reason for the

deviation and propose an alternative sample location.  

Turbidity will be measured using a turbidimeter properly calibrated according to the operator’s manual.

The effluent limitation for turbidity is 25 NTU at the point where stormwater is discharged from the site or nor

more than 5 NTU over background turbidity when the background turbidity is 50 NTU or less, or have more than a

10 percent increase in turbidity when the background turbidity is more than 50 NTU. If water quality sampling at

half the distance between the activity and the point of compliance downstream of the activity indicates that the

turbidity plume compared to the background turbidity exceeds the 5 NTU or 10 percent increase, Northwest will

reduce or eliminate the rate of activity immediately until turbidity at half the distance between the activity and

the point of compliance downstream is within the turbidity criteria. After such an event, Northwest will assess the
5 WATERBODY CROSSINGS 

5-2 

efficacy of the site best management practices and update or improve the best management practices used at the

work site in an effort to reduce or prevent recurrence of the turbidity exceedance in the waterbody (state

waters).

5.3 Reporting 

The first monitoring period begins on the effective date of the permit. Monitoring results shall be submitted to

Ecology monthly. Monitoring data obtained during each monitoring period shall be summarized, reported, and

submitted on the DMR forms. DMR forms shall be received electronically through Ecology’s WebDMR program

(http://www.ecy.wa.gov/programs/wq/permits/paris/webdmr.html) no later than the 15th day of the month

following the completed monitoring period.  

If Northwest is unable to submit electronically (for example, those who do not have an internet connection) must

contact Ecology to request a waiver and obtain instructions on how to obtain a paper copy DMR at:

Department of Ecology

Water Quality Program

Attn: Stormwater Compliance Specialist

P.O. Box 47696

Olympia, WA 98504‐7696

If Northwest obtains a waiver not to use WebDMR, it must use the forms provided to them by Ecology; submittals

must be mailed to the address above.  

DMRs must be submitted monthly whether or not the WEP was discharging. If there was no discharge during a

given monitoring period, Northwest will submit the form as required, with the words “No discharge” entered in

the place of monitoring results. For outfalls that had discharges during a given monitoring period, detailed DMR

forms for each associated discharging outfall must be submitted.

5.4 Records Retention 

Monitoring and sampling reports will be retained as part of this Water Quality Monitoring Plan.

5.5 Noncompliance Notification 

If the results of visual inspections or turbidity monitoring/sampling exceed the 250 NTU phone reporting level

value at the point of discharge, Northwest will immediately telephone the Ecology Northwest or Southwest

Region’s Environmental Report Tracking System within 24 hours. Northwest will immediately take action to

prevent the discharge/pollution, or otherwise stop or correct the noncompliance, and, if applicable, repeat

sampling and analysis of any noncompliance immediately and submit the results to Ecology within five (5) days of

becoming aware of the violation.

Northwest will provide Ecology with the following information:

1. A description of the nature and cause of noncompliance, including the quantity and quality of any

unauthorized discharges

2. The period of noncompliance, including exact dates, durations, and times and/or the anticipated time when

Northwest will return to compliance

3. The steps taken, or to be taken, to reduce, eliminate, and prevent recurrence of the noncompliance

Reports summarizing the scope of inspections, the personnel conducting the inspections, the results of turbidity

sampling (both visual and physical), the dates of the inspections and/or sample events, and actions taken as a

result of the inspections or monitoring results will be prepared and submitted to Ecology bi‐weekly (every other

week).
6-1 

SECTION 6

Hydrostatic Test Water 

6.1 Monitoring and Sampling 

Northwest plans to discharge hydrostatic test water within several test segments and waterbodies along the right‐

of‐way. All hydrostatic test water will be discharged to a discharge structure (straw bale containment structure)

and at no time is the water allowed to flow into rivers, streams, lakes, ponds, wetlands, or other surface

waterbodies (other than as minor seepage after the discharge has been treated through the straw bale

containment structure). Any minor seepage shall not result in erosion or scouring of the rivers or creeks. The

volume of the discharge shall not exceed 10 percent of the river or creek flow at the time of the discharge and

shall not result in a visible increase in turbidity in the receiving water. Prior to and during the discharge, whichever

is applicable, monitoring shall take place for the following parameters:

 Flow. The volume of the discharge shall be measured in gallons (per batch).

 TPH. Prior to discharge, the hydrostatic test water shall be monitored for TPH. The maximum daily TPH

effluent limitation for discharge of the hydrostatic test water is 10 milligrams per liter.

 Chlorination. Northwest shall test the source water for chlorine. If chlorine levels are at a concentration of

0.1 parts per million or less, no further testing is required. If the chlorine levels are at a concentration of

greater than 0.1 parts per million, Northwest shall ensure that all discharges occur to the land surface for

infiltration.

 pH. Monitoring for pH is only required if engineered soils are used in the catchment where the water is being

discharged. If engineered soils are used, monitoring (a grab sample) shall be conducted for pH (per batch).

The effluent limitation for discharges to groundwater for pH is in the range of 6.5 to 8.5 standard units. (pH

monitoring is not expected to be necessary.)  

 Oily sheen. The hydrostatic test water and the water in the discharge structure shall be visually inspected (per

batch) for an oily sheen.

 Diesel range petroleum hydrocarbons, or heavy oils. Northwest shall inspect the soils after infiltration is

complete and if there is a visible layer of petroleum hydrocarbons on the soils, composite soil samples shall be

collected from a depth of 0 to 12 inches at an area where a layer of petroleum hydrocarbons is observed. The

effluent limitation for diesel range petroleum hydrocarbons or heavy oils is 2,000 milligrams per kilogram.

6.2 Reporting 

Reporting requirements are the same as described in Section 5.2, Monitoring and Sampling, of this plan.

6.3 Records Retention 

Records of all monitoring information (site log book, inspection reports/checklists, etc.), this Stormwater Pollution

Prevention Plan, and any other documentation of compliance with permit requirements will be retained during

the life of the construction project and for a minimum of three years following the termination of permit coverage

in accordance with permit condition S5.C of the Construction Stormwater General Permit. 

6.4 Recording of Results 

For each measurement or sample taken, Northwest shall record the following information:

 Date, exact place, method, and time of sampling or measurement

 Individual who performed the sampling or measurement
6 HYDROSTATIC TEST WATER 

6-2 

 Dates the analyses were performed

 Individual who performed the analyses

 Analytical techniques or methods used

 Results of analyses

6.5 Noncompliance Notification 

Noncompliance notification is the same as described in Section 5.5, Noncompliance Notification, of this plan.

6.6 Laboratory Analyses 

Prior to construction, Northwest will select a laboratory properly certified with the State of Washington to

perform analyses of water quality samples. Prior to release of the hydrostatic test water, the water in the pipe

shall be sampled for TPH. Bottles from the laboratory must be used to collect the sample. A supply of bottles

should be obtained from the laboratory and kept onsite so that they are readily available prior to the discharge.

Chain‐of‐custody forms will be supplied by the laboratory and must be used. The sample bottles may have

preservative in them and care should be taken to not spill the preservative when collecting the sample. Once the

sample is collected, it should be driven or shipped overnight to the laboratory. The water should not be

discharged from the pipe to the discharge structure until the results of the analysis are known.  

If, after all the water has infiltrated to the ground, there is a visible layer of oil on the soil, a composite sample of

the soil shall be obtained and sent to the laboratory for analysis.

HORIZONTAL DIRECTIONAL DRILLING

MONITORING AND CONTINGENCY PLAN

J4-1 

Horizontal Directional Drilling Monitoring and 

Contingency Plan 

This horizontal directional drilling (HDD) monitoring and contingency plan provides specific preventative and

mitigative measures to be used by Northwest Pipeline GP (Northwest) and its contractors during HDD installation.

This is a preliminary plan, and specific procedures will be developed during final design for each location based on

site‐specific conditions. HDD operations potentially pose a risk to wetlands and waterbodies through an

inadvertent release of drilling fluid. An inadvertent release occurs when the drilling fluid seeps through fractured

overburden soil and finds a path to the ground surface. Drilling fluid typically consists of a mixture of bentonite,

water, and soil cuttings. This mixture is not hazardous or toxic, but it could affect the water quality of any

waterbody if introduced.

Inadvertent release can occur at any place along any point of an HDD installation, although they are more likely to

be observed at the entry and exit points (locations where the drilling bit or head is shallow). If an inadvertent

release occurs and no control measures are in place, the drilling fluid could potentially reach the surface water or

wetland that is above the HDD installation. The contingency plan detailed in the following subsections will outline

measures to minimize the potential for an inadvertent release. This plan also addresses the methodology that will

be used to detect inadvertent releases, as well as countermeasures to be taken should an inadvertent release be

detected.

Planning and Prevention 

HDD crossings will be conducted only during recommended in‐water work periods to minimize impacts from a

potential inadvertent release. Northwest will use nontoxic bentonite‐clay mixtures of drilling mud to assure that,

if an inadvertent release occurs, it will not result in toxicity to aquatic life in the stream.

The contractor performing the HDD must have experienced personnel onsite who are familiar and experienced

with the procedures for this type of installation. Before drilling activities begin, the contractor must submit any

certifications and documentation of at least 2 years of experience for all personnel who will be performing drilling

work. The Environmental Inspector must inspect all HDD activities with additional oversight from a utility

inspector when available. Before any HDD occurs, a safety meeting will take place, the inadvertent release

contingency plan will be discussed, and any questions will be answered.

From the day‐to‐day maintenance routine, the drilling personnel will be aware of what materials are critical

during an inadvertent release and assure that these items are on hand. Because drilling fluid seepage resulting

from an inadvertent release can be easily controlled on land where it has the greatest potential to occur,

containment items such as lumber for temporary day operation and shoring, sand, portable pumps, hand tools,

silt fence, and hay bales will be stored at the drilling sites. The drilling contractor will also have heavy equipment

such as backhoes that can be used to control and clean up drilling fluid seepage.

Before drilling, the work area(s) will be flagged and the limits defined. Erosion and sediment controls (including

silt fence, straw wattles, and temporary sediment trap) will be installed at the entrance and exit pits as needed to

control surface erosion or migration of drilling fluid. Additional materials will be kept onsite at a designated

location, and the presence of these materials will be verified in advance of any drilling activities. These materials

will be placed in a dedicated location and denoted as the inadvertent release containment response kit. The kit

will contain the following items:

 Silt fence

 Straw wattles

 Silt curtain (in‐water work)

 Straw bales

 Submersible pumps
J4-2 

 Specialized filters

 Generator

 Appropriate hand tools

 Vacuum truck (available on call)

 Light towers for work at night

 Heavy equipment, such as backhoe or dozer, for containment and cleanup of drilling mud

 Boat for major waterbody crossings to allow for monitoring of releases to water

Inadvertent Release Monitoring 

Once HDD begins, monitoring will be performed to determine whether an inadvertent release could occur. The

bentonite mixture will be adjusted to match the conditions of the subsurface. The pressure levels will be set as

low as possible, and the levels will be closely monitored to verify that the pressure on the drilling fluid is set to

match the formation. The pressure should not exceed what is needed to penetrate the formation.

HDD is a technically advanced process involving skilled operators. The detection of an inadvertent release before

it occurs is highly dependent on the skills and experience of the drilling crew. Each drilling situation is unique in

that the behavior of the subsurface material is variable and difficult to predict. In‐hole monitoring equipment for

detecting an inadvertent release is not available. Detection of an inadvertent release relies on the proper

interpretation of site‐specific conditions with the potential to cause an inadvertent release. For this reason,

Northwest will use firms that specialize in HDD to perform the HDD crossings. The selection and supervision of

this drilling contractor will be the responsibility of Northwest.

An inadvertent release occurs when pressure in the hole is no longer maintained. The most obvious signs of an

inadvertent release are surface seepage or loss of circulation of the drilling fluid. One of the functions of the

drilling fluid is to seal the hole to maintain the downhole pressure. During drilling, the pressure will be closely

watched and randomly checked by the Environmental Inspector (EI) or utility inspector. As the boring progresses,

the pressure will be inspected and documented. Any drop in the pressure could indicate a potential inadvertent

release, and drilling will be halted at the discretion of the EI. However, some loss of drilling fluid is also normal in

the drilling process. During the drilling process, loose sand, gravel layer, or rock fracture could be encountered.

These occurrences will require additional drilling fluids to fill in the voids. Consequently, drilling fluid loss in and of

itself is not an indication of an inadvertent release. The loss of drilling fluid in combination with other factors may

indicate a potential inadvertent release. For example, if there is a loss of drilling fluid and the return cuttings do

not show a large quantity of gravel, then a loss of containment pressure within the hole may have occurred.

Inadvertent Release Response 

Should the results of the monitoring indicate that an inadvertent release has occurred, the drilling will be stopped

immediately and corrective actions implemented. The only pressure causing the inadvertent release to occur is

the pressure from the drilling fluid pumps. Therefore, the most direct corrective action is to stop the drilling fluid

pumps. By stopping the pumps, the pressure in the hole will quickly bleed off. With no pressure in the hole, the

inadvertent release will stop. As soon as surface seepage is detected, the pumps will be stopped temporarily until

the response process has contained the release. Once the cleanup process has contained the release, drilling

activities will immediately resume while monitoring the pressure to prevent additional inadvertent release.

If an inadvertent release occurs in the waterbody, there may be a visible plume. Minor seepage may be difficult to

detect owing to the turbidity of the waterbodies and the high specific gravity of bentonite clay drilling fluid. Only

minimal pressure will occur to disturb sediments because of the distance that the drilling fluid must travel to

reach the surface. The composition of the drilling fluid is primarily water and bentonite clay. If a small amount is

released into the creek, the currents will quickly dissipate the inadvertent release. If seepage is detected in the

creek, the drilling activities will continue, but corrective measures, if any, will be taken to try to minimize the

seepage. If an inadvertent seepage does occur in the waterbody, it will be monitored and documented, but

drilling activities will not be suspended unless returns create a threat to public health and safety. Additionally, no

cleanup work in the waterbodies is proposed in response to a minor inadvertent release.
J4-3 

There is greater potential for an inadvertent release at the entry and exit locations. In the contingency planning

for the HDD crossings, drilling fluid seepage at the entry and exit locations has been considered, and preventive

actions have been developed. The entry and exit locations on all HDD crossings have dry land segments where

drilling fluid seepage can be easily detected and contained. To isolate and contain potential drilling fluid seepage

at each of the drill sites, a berm can be built around the entire drilling site area. Hay bales or silt screen can also

be part of the berm on the water side of the drilling area. To contain and control drilling fluid seepage on the land

area, earth‐moving equipment such as backhoes or small bulldozers, portable pumps, sand, silt fences, and hay

bales will be available at each of the drilling sites. Any drilling fluid seepage will first be contained and isolated

using dirt berms, hay bales, or silt screens. The seepage will then be immediately cleaned up from the area and

hauled or pumped to one of the storage pits at the closest drilling site.

After the drilling fluid seepage has been contained, the drilling contractor and Northwest will make every effort to

determine why the seepage occurred. Once Northwest has determined the cause of the seepage, measures will

be developed to control the factors causing the seepage and to minimize the chance of recurrence. Developing

the corrective measure will be a joint effort of Northwest and the drilling contractor and will be site and problem

specific.

In some cases, the corrective measure may involve a determination that the existing hole encountered a void,

which could be bypassed with a slight change in the profile. In other cases, it may be determined that the existing

hole encountered a zone of unsatisfactory soil material and the hole may have to be abandoned. If the hole is

abandoned, it will be filled with cuttings and drilling fluid.

Inadvertent Release Notifications 

In the event of an HDD drilling fluid release to waterbodies, sensitive areas, or riparian areas, appropriate local,

state, and federal agencies will be notified. All appropriate agencies will be notified of the inadvertent release

within 24 hours. Table 1 lists the agencies that will be notified. The following information will be provided to

agencies:

 Time of inadvertent release

 Location of release

 Quantity and type of material released and amount of recovered materials

 Containment and cleanup measures

 Location of sensitive areas near the release

Abandonment and Contingency 

A borehole will need to be abandoned if an inadvertent release cannot be avoided, or if an inadvertent release

has occurred that cannot be controlled. The borehole will be completely abandoned and a new location

determined. Any borehole abandonment locations will be documented and shown on any as‐built documents.

If corrective actions do not prevent or control unacceptable releases of drilling fluid, Northwest may opt to redrill

the hole along a different alignment. The HDD borehole will not simply be abandoned completely if difficulties are

encountered during drilling or reaming of the borehole, or during pipe pullback operations. In fact, complete

abandonment of an HDD borehole rarely occurs within the industry. Before abandoning a borehole, the HDD

contractor will implement remedial measures to attempt to resolve the problems without the need for

abandonment of the borehole. However, if problems with the borehole or section of the borehole cannot be

resolved, the affected section of the borehole will be filled with grout, consisting of nontoxic, nonhazardous

materials, to preclude communication between nearby boreholes. The following procedures will be implemented

to abandon the drill hole:

 To seal the abandoned drill hole, thickened drilling fluid will be pumped into the hole as the drill assembly is

extracted, and plugs will be used to create a cap.

 Closer to the surface at drilling locations (within approximately 10 feet of the HDD entrance), a soil cap will be

installed by filling the borehole with soil extracted during construction of the pit and berms.

 The borehole entry location for HDD segments will be graded and seeded by the contractor to its original

grade and condition after the drill hole has been abandoned.

 The contractor will drill a second pilot hole beginning near the initial entry point along a track that parallels

the initial borehole.

A root cause analysis of the failed HDD will be conducted to minimize the risk of subsequent failure. The root

cause analysis will guide the development of potential alternatives for the drilling plan. Depending on the cause of

a failure, it would be preferable to continue to use the partially drilled pilot hole already underway, and simply

redirect the drilling deeper or laterally around the cause of the failure, if possible, rather than initiate a secondary

pilot hole.

If the cause(s) of the failure indicate that a completely new, “secondary” pilot hole is necessary, the separation

distance required will depend entirely on the cause of the failure. Northwest anticipates that only the drill

alignment between the original entry point and exit point will be adjusted deeper or laterally such that no

additional work areas will be required. Before the initiation of a completely new “secondary” pilot hole, a

modification request would be provided to the appropriate agencies.
