4 DESCRIPTION OF UNDERTAKING

GWNT-DOT is submitting a Water Licence Application to the Northwest Territories Water Board

(NWTWB), to authorize certain activities associated with construction of the Inuvik to Tuktoyaktuk

Highway pursuant to requirements of the Northwest Territories Waters Act and the Northwest Territories

Waters Regulations.

The ITH project is a proposed 140 km all-season highway between the Town of Inuvik and the Hamlet of

Tuktoyaktuk in the ISR. The ITH project has undergone substituted panel review by the Environmental

Impact Review Board (EIRB) pursuant to the Inuvialuit Final Agreement and the Canadian Environmental

Assessment Act. The EIRB concluded in its decision report of January 25, 2013 that the ITH project will

result in significant impacts to the environment, but that these impacts can be mitigated through the

implementation of 51 recommended measures (Appendix G, EIRB 2013). The Governments of Canada

and Northwest Territories have responded to the EIRB’s report by accepting, accepting the intent or

rejecting each of the EIRB’s recommendations (Appendix H, Government of Canada 2013).

The EIRB’s recommendations were based on the scope of the development as shown in Table 4-1.

4.1 Project Details

Throughout this discussion, construction activities are described as being undertaken in either “winter” or

“summer”. For the purpose of this application, “winter” is defined as the period between approximately

November 15 and April 30, and “summer” is considered to be the period between May 1 and

November 14. These periods may change annually based on snow and ground conditions.

4.1.1 Embankment Construction

Approximately 40 km of new alignment will be constructed each winter, along separate spreads, each

approximately 20 km in length. Construction spreads will progress from North to South (beginning at

Source 177 Access Road), and South to North (generally beginning at the end of Navy Road, within the

ISR). Progressive spreads constructed each winter will begin at the end of the embankment constructed

the previous winter. Construction of the embankment for the ITH project will occur during the winter

months to protect the ice-rich terrain along the alignment and to establish a frozen core embankment for

the highway.

Embankment material will be sourced from borrow pits authorized for use on the project. Material will be

hauled directly from borrow pits to the end of constructed embankment, where it will be “end-dumped”

over geotextile fabric, and leveled. Successive “lifts” (thicknesses) of material will be placed until the

specified thickness is achieved.

Surfacing and grading of constructed embankment will be conducted in summer, once the constructed

embankment is able to support heavy equipment: during mid-July to late September. During this time,

compaction of the embankment and installation of insulation in certain areas may also be completed.

Material suitable for surfacing will be sourced from approved sources and will have been stockpiled along

the embankment in winter.

4.1.2 Watercourse Crossings Construction

The ITH from Kilometer Post (KP) 0 to KP 119 crosses 65 watercourses. In summer 2012, a

hydrotechnical field assessment of the stream crossings was completed to obtain site specific information

for the design of each watercourse crossing (KAVIK-STANTEC 2012e). Specific information collected on

each watercourse crossing including geographic coordinates (UTM based), channel descriptions,

topographical information including channel cross sections, elevation, water velocity measurements, and

photographs. A desktop hydrologic analysis was completed to estimate the 2-year, 10-year, 20-year,

50-year and 100-year return flow for each watershed along the proposed highway. A copy of this study is

included in Appendix B of KAVIK-STANTEC’s (2012e) Hydrotechnical Assessment of Stream Crossings

(provided in Appendix D.3). This information was used to complete an advanced design of the size and

type of the crossings for each of the 65 watercourses. A final design is expected in August 2013.

Fish and fish habitat related assessments have also been undertaken at select watercourse crossings

with potential fish habitat (Appendix D.4, D.5, D.6).



June 2013

4-5

The construction of the watercourse crossings will be concurrent with the construction of the new highway

embankment. Crossing structures will comprise culverts, large diameter bridge culverts, and bridges.

Final crossing designs will be submitted to support applications for fisheries authorizations.

Three crossing categories are proposed for the ITH project. The crossing locations, categorized by type,

are shown in Figure 3-2 and the Watercourse Crossing Atlas (Appendix C). The crossing types include:

Culvert crossings – crosses watercourses that are small in width, with peak 100-year flows of up to 3.0

metres/second (m3/s). Culvert structures of minimum 1,200 mm diameter will be used. A type section

drawing of a culvert is shown in Figure 4-1.

Large diameter bridge culvert crossings – will be used to cross watercourses with larger wetted widths

than culvert crossings and with peak 100-year flows of between 3.0 m3/s and 4.0 m

3/s. A type section

drawing of a large diameter bridge culvert is shown in Figure 4-2.

Major bridge crossings – typically crosses watercourses larger in width than watercourses crossed by

large diameter bridge culvert crossings, and with peak 100-year flows greater than 4.0 m3/s. A type

section drawing of a major bridge crossing is shown in Figure 4-3.

Final crossing designs will be available in August 2013.

The crossings types and geographic coordinates are listed in Table 4-3 and shown on Figure 3-2.

There are nine watercourse crossings greater than 5 m wide at the ordinary high water mark, as

assessed by KAVIK-STANTEC in Hydrotechnical Assessment of Stream Crossings (2012e,

Appendix D.3). These crossings include 3, 4, 13A, 18, 21, 30A, 31, 35, A2a; their locations are shown on

the Watercourse Crossing Atlas (Appendix C).

The in-stream activities for closed bottom culvert installations will be confined to winter months, when all

locations are anticipated to be frozen to the bottom. In-stream activities are described in the following

subsections.

4.1.2.1 Bridge Crossings

Bridges and bridge foundations will be constructed at up to eight watercourse crossing locations

(Table 4-3). Bridge foundations will be constructed concurrent with embankment construction - within

spreads to be constructed each winter.

The construction of the foundations at most bridge crossings consists of:

installation of pilings (January - February) - these piles will be located outside of the stream channel in

all cases. No piles will be installed within the normal flow channel. The ad-freeze piles will be bored

into the stream bank, the cutting material hauled away for disposal, the piles installed in the boring,

and a sand slurry mix poured into the hole to bond the pile to boring wall.

installation of foundations/abutments and wing walls (February - March) - these abutments and wing

walls are installed on top of the piles, out of the stream bed itself. As such there is no work in the

stream itself on these items.

launching girders (May)

placement of erosion control (April - May) - erosion control may consist of placement of large diameter

clean rock, hand placed from the edge of the stream bed covering the embankment and protecting the

piles, abutments, and wing walls from erosion. Erosion control will be conducted in a manner

consistent with the Sediment and Erosion Control Plan (Appendix E.1).

While bridge foundations are being constructed, a winter ice bridge or snow fill detour will be constructed

adjacent to the works to allow movement of equipment around the construction site. Decking will be

placed in winter, but final manual installation of railings will be completed in summer.

4.1.2.2 Culverts

The embankment construction will include the placement of small and large diameter culverts for

watercourse crossings and to prevent ponding along the edges of the embankment (equalization

culverts). These crossing locations are distributed along the length of the highway. Culvert installation will

be concurrent with embankment construction along that section.


June 2013

4-14

The placement of large diameter culverts will occur after the stream to be crossed has frozen to the

bottom, and will involve the following steps:

excavation of ice out of the streambed to the installation elevation

sub-excavation, if required (at the present time, sub-excavation is not anticipated for any crossing)

placement of suitable granular material as the foundation bedding

compaction, installation of the culvert and backfilling

placement of erosion control as required

All culvert crossings are anticipated to be frozen to the bottom during installation. However, if it is found

that installation will be required in a stream that does not freeze to the bottom, an isolated crossing

construction will be applied with appropriate approval from DFO.

The final design of culverts, including consideration of diameter, material, and closed- versus open-

bottom culverts will be determined as a part of final design. Final design will also specify the type of

culvert to be constructed at each crossing location.

While culverts are being constructed, a temporary winter ice bridge or snow fill detour will be constructed

adjacent to the works to allow movement of equipment around the construction site.

4.1.3 Borrow Pit Development

Borrow pits will be developed to provide material for embankment construction. Up to fourteen borrow pits

may be developed during the three to four year construction period. A number of these borrow sources

may be used for more than one year of winter construction. The development and use of material from six

of these borrow sources was included within the scope of the EIRB’s review. Eight additional sources are

being considered for development and use during the construction period, as identified in Table 4-4. All

borrow sources potentially to be used for project construction will require authorizations from Aboriginal

Affairs and Northern Development Canada or the Inuvialuit Land Administration. Use of Source 177 is

already authorized. Applications for land use permits, quarry licences and quarry permits will be

submitted in August 2013.

PRIMARY CONSTRUCTION PLAN – SIX BORROW SOURCES

A project construction plan has been developed around use of the six sources previously included within

the EIRB’s review (the “primary construction plan”), summarized in Table 4-5 and shown in Appendix B.

Borrow pit development will consist of:

construction of winter roads for hauling material

removal and stockpiling of overburden

blasting or ripping of material

temporary stockpiling of material

material hauling

erosion control and meltwater management

progressive (annual) reclamation of areas of the pit

Pits will be developed in accordance with the associated Pit Development Plan, to be approved by

Aboriginal Affairs and Northern Development Canada or Inuvialuit Land Administration, as part of

authorizations issued for individual pit development.

Borrow pits will be developed and operated in winter. During late summer (August – September), some

local grading and stockpiling may be undertaken at the source using equipment stored there during

summer. Winter camps and equipment will be stored during the summer at borrow sources, on a pad of

adequate thickness to protect permafrost. No summer road access to borrow pits will be required.

The methods for developing and operating these six borrow sources will apply to all sources proposed for

construction and will be detailed in pit development plans.

OPTIONAL CONSTRUCTION PLAN – FOURTEEN BORROW SOURCES

Use of other borrow sources identified in Table 4-6 is at this time optional, although preferred, and

described as the “optional construction plan”. The integration of optional sources into the construction

plan is being considered because it will reduce environmental effects, reduce project costs and improve

construction efficiency. Use of optional borrow sources during construction will:

Reduce the length of winter roads to be constructed

Limit operation of borrow sources to 1-2 construction seasons

Minimize need to construct winter roads to borrow sources over multiple seasons

Allow camps located at borrow sources to be closer to the alignment

Reduce project costs by reducing haul distance

The “optional” (yet preferred) integration of additional borrow sources is summarized in Table 4-6 and

illustrated in Appendix B.

The GNWT-DOT made several commitments to mitigate effects from borrow pit development and

operation during the EIRB review process (Appendix I), and the EIRB made a number of

recommendations necessary to mitigate effects from borrow pit operations (Appendix G). GNWT-DOT

expects that these mitigations would apply to all fourteen borrow sources proposed for construction.

4.1.3.1 Additional Studies Required for Borrow Sources

Geotechnical investigations of all potential borrow sources to be used for construction have been ongoing

in 2012 and 2013, and additional investigations are planned for 2014. These investigations confirm the

volume, quality and extent of material, and will support applications for regulatory authorizations. All

geotechnical investigations of these fourteen proposed borrow sources were completed with the

appropriate permits and consultation with Inuvialuit organizations (KAVIK-STANTEC 2012a, 2012f).

During these consultations, GNWT-DOT communicated that the purpose of these investigations was to

identify additional potential borrow sources for use during project construction.

identified (Appendix B). Winter camps and borrow pit equipment will be stored during the summer at

borrow sources, on a pad of adequate thickness to protect permafrost.

Four camps will be operated in summer. Summer camps will have a capacity of 20 people, and will be

located on previously constructed embankment. Summer camps will support activities to be conducted

along the embankment, including compaction, grading and installation of railings.

Fuel storage areas will be needed at each camp location or at equipment and materials staging areas.

Diesel and gasoline will be required to support construction and camp operations. Fuel will be supplied

from Tuktoyaktuk and Inuvik, and refueling of vehicles will be undertaken either at the fuel storage

location, or at designated locations along the construction spread. Fuel will remain stored at camp

locations to be operated the following winter.

Five anticipated waste streams will be generated during the construction operations:

camp greywater

camp sewage

camp solid waste

recyclables

hazardous waste

The construction camps will utilize waste management facilities (greywater, sewage, solid waste and

recyclable waste) in both Inuvik and Tuktoyaktuk for the treatment and disposal of the waste generated at

the camps. Negotiations for this waste management service have been initiated with both communities.

Hazardous waste will be managed independently using the appropriate contracted resources for

collection, transport and ultimate disposal.

During construction, equipment maintenance will be required, and materials such as culverts and bridge

decks may need to be temporarily stored until emplacement. Designated areas will be constructed during

winter to allow for equipment and materials storage and maintenance. These storage and maintenance

areas will be located on or adjacent to borrow sources or constructed embankments.

4.2 Abandonment Plan

Reclamation plans will be included in each Pit Development Plan to be approved by the appropriate

regulator in accordance with the requirements of the Inuvialuit Settlement Region Granular Resources

Management Plan (ILA and INAC nd). A table of contents for a Pit Development Plan is provided in

Appendix E.4. GNWT-DOT is in discussion with Aboriginal Affairs and Northern Development Canada

and the Inuvialuit Land Administration regarding the content and details of such plans. The highway itself

is a permanent public infrastructure and as such, will not be abandoned.


June 2013

4-20

4.3 Proposed Time Schedule

Construction activities are planned to begin December 2013 and will be completed in September 2017.

The primary embankment construction activities shown in Table 4-7 ends in Summer 2016; however, it is

anticipated that some additional grading activities may carry over during Winter 2016-17 and Summer

2017. The program will experience periods of shutdown from approximately May 1 to July 15 each year.

Table 4-7 summarizes generally, the timing of construction activities in winter and summer.

A fourth winter of construction (2016-17) may be required to complete embankment construction,

including placement of surfacing material.

Certain additional pre-construction studies are planned. These are summarized in Table 4-8.

7 WATER USE

The proposed water uses associated with the ITH project are:

To obtain water

To cross a watercourse

To modify the bed or bank of a watercourse (installation of culverts)

7.1 Obtaining Water

Water will be obtained for the purpose of daily camp operations and winter road construction. The use of

water will range from 32 m3/day, to 1,524 m

3/day during a short period of approximately 6 weeks. Water

use varies significantly throughout a construction year, depending on the construction period. Details are

provided in Section 8.

7.2 Crossing Watercourses

As discussed in Section 4.1.2, nine watercourses greater than 5 m wide at the ordinary high water mark

will be crossed.

7.3 Modifying the Bed or Bank of a Watercourse

The ITH project involves modifying the bed or bank of watercourses with continuous water flow and of

watercourses greater than 5 m wide at the ordinary high water mark (see Section 4.1.2).

Construction of all watercourse crossings, as described in the previous section, will require modification of

the bed or bank of the watercourse. The construction of bridges will require the excavation and

modification of “bed and banks” for the installation of pilings, the installation of foundations and

embankments and the placement of erosion control. All of these works will be undertaken during the

winter months when the bed and banks are in a frozen condition. The construction of culverts will also

require modification of “bed and banks”. The placement of large diameter culverts will occur after the

stream to be crossed has frozen to the bottom, and will involve the excavation of ice out of the streambed

to the installation elevation, sub-excavation (if required), placement of suitable granular material as the

foundation bedding and compaction, installation of the culvert and backfilling.

8.1 Winter Access Road Construction

Water will be used for the construction and maintenance of winter and ice roads.

During construction, there are four distinct water use periods per construction year (November 15 to

November 14). From approximately November 15 to December 31, the maximum quantity of water used

per day may be up to 1,500 m3

(1,500,000 litres) to construct winter roads; this would be 700 m3

per day

at the northern construction spread, and 800 m3

per day at the southern construction spread. After the

roads are constructed, the water withdrawal rates decline significantly, to approximately 200 m3

(200,000

litres) per day (total of both spreads), from January 1 to May 15 for continued winter road construction

and maintenance, then 20 m3

(20,000 litres) per day (total of both spreads) from May 16 to November 14

for compaction of the embankment material and the final granular surfacing.

Table 8-6 identifies the per day cubic metre water use in each construction spread within each annual

construction period and the annual domestic water use.

The total annual water quantity required for the ITH project is approximately 107,724 m3; approximately

48,230 m3at the northern construction spread, approximately 52,930 m

3at the southern construction

spread, and approximately 6,564 m3

for domestic camp use. Water use will peak for a period of

approximately six weeks during the annual construction period.

The water used for the construction of winter roads will not be returned to source, except where it exists

as an overwater ice road. Melt water is expected to slowly infiltrate into the active layer.

Water withdrawal will be in accordance with the DFO’s (2010) Protocol for Water Withdrawal from Ice-

covered Waterbodies in the Northwest Territories and Nunavut, whereby no more than 10% of available

water will be withdrawn from any waterbody (Tables 8-3, 8-4, 8-5).

The operating capacity of the submersible pump will be 45 litres per second (600 gallons per minute) and

the size of the intake screen will be 0.70 m2

and will conform to DFO’s (1995) Freshwater Intake End-of-

Pipe Fish Screen Guideline and (2011) Fish Screen Design Criteria for Flood and Water Truck Pumps.

8.2 Camp Water Use

Domestic water use will include cooking, bathing, toilet, and laundry related activities. Bathing, toilets and

laundry are the largest consumers of water; therefore, low or no-flow toilets and low water use showers

and laundry facilities will be used at the camps. A maximum of approximately 6 m3

(6,000 litres) per day

will be required during peak construction periods, for a 60 person camp. It is estimated that each person

will use up to 100 litres of water per day. This is approximately 24 m3

(24,000 litres) of water required per

day over the four camps operating in the northern and southern spreads during peak construction

periods.

Bottled drinking water for camp use will be supplied from the Hamlet of Tuktoyaktuk and the Town of

Inuvik.

8.3 Water Sources

Tables 8-3 to 8-5 lists the approximately 50 potential water sources identified over the length of the all-

weather highway to provide water for the winter and ice road construction. The locations of these water

sources are shown on the Construction Atlas (Appendix B). The bathymetric investigation of many of

these water sources has been completed (Appendix D), and the remainder of the bathymetric

investigations will be completed in 2013 (as identified in Table 4-8). The bathymetric investigations will

form the basis of the final selection of the water sources to be used in the road construction in compliance

with DFO’s (2010) Protocol for Water Withdrawal from Ice-covered Waterbodies in the Northwest

Territories.

Bathymetric surveys for the identification of the appropriate water source have been undertaken using

two different methodologies. Winter bathymetric surveys were completed over ice using Ground

Penetrating Radar (GPR) to measure the depth of the water along several cross sections of a given lake

(Kiggiak-EBA 2013). Summer bathymetric surveys were completed from a boat using sonar depth

recording and Global Position System (GPS) position recording (IMG-Golder 2012b).

DFO will require that fish be protected from entrainment or impingement where water is extracted from

fish-bearing waters, including any water withdrawals made using water trucks. DFO has a Freshwater

Intake End-of-Pipe Fish Screen Guideline and Fish Screen Design Criteria for Flood and Water Truck

Pumps to assist proponents in the design and installation of fish screens.


Section 9: Waste Deposited

June 2013

9-1

9 WASTE DEPOSITED

During the construction activities for the Inuvik to Tuktoyaktuk Highway various waste materials will be

generated, and various hazardous materials will be utilized. Methodologies have been developed for the

collection, transportation, treatment and disposal of the waste materials generated during the construction

activities with no anticipated deposition of the waste as part of project operations. In addition,

methodologies have been developed for the transportation, storage, containment, and utilization of the

various hazardous materials utilized during the construction activities with no anticipated deposition of

the hazardous materials as part of project operations.

Contingency plans for managing accidental discharges of waste materials or hazardous materials have

been developed to manage unanticipated events.

9.1 Waste Materials Generated

Five types of waste will be generated during construction operations, none of which will be discharged to

land or in or near any waterbodies. The waste types include:

camp greywater

camp sewage

camp solid waste

recyclables

hazardous waste

9.1.1 Greywater and Sewage

Management of greywater and sewage will include the storage of wastewater generated at the

construction camps (if required) and the periodic transport and disposal of sewage waste. Sewage from

no-flow (Pacto) or low flow toilets will be stored in sealed watertight containers and transported to

approved sewage lagoon facilities at either Tuktoyaktuk or Inuvik.

Greywater will be stored using approved holding tanks and will not receive any treatment while stored. All

camp greywater will be stored in 14,000 litre skid-mounted tanks. Full tanks will be transported to

approved wastewater facilities in Tuktoyaktuk or Inuvik.

The largest camps associated with the construction will have capacity for up to 60 people, depending on

the construction season. The wastewater generation associated with the maximum number of people (60

people) will be approximately 6 m3

(6,000 litres) per day per camp during the winter construction season

(November to May), or up to 24 m3

(24,000 litres) per day including all camps at both the northern and

southern spreads. Less wastewater will be generated during summer construction activities.

Water Licence Application for Construction of Inuvik - Tuktoyaktuk HighwaySubmission to the Northwest Territories Water BoardSection 9: Waste Deposited

June 2013

9-2

Each camp location will typically have a three day supply of water and wastewater storage available,

approximately 18-20 m3

(18,000-20,000 litre) each, with an additional 45 m3

(45,000 litre) insulated skid

mounted tank at each winter camp as additional storage in the event of a blizzard or other unforeseen

event.

The Town of Inuvik operates under a water licence with the Gwichin Land and Water Board, and the

Hamlet of Tuktoyaktuk operates under a water licence with the NWTWB. Waste transfer agreements will

be negotiated with municipalities prior to construction.

There are no alternative methods for sewage and greywater treatment/disposal proposed, as package

treatments plants with subsequent discharge to land may be ineffective and unreliable for this type of

sensitive environment and cold climate.

9.1.2 Solid Waste

The management of solid waste from the camps and construction activities may include incineration or

the storage of the solid waste and the periodic collection of the wastes in a covered container vehicle.

The vehicle will haul the waste to the waste disposal facilities at either Tuktoyaktuk or Inuvik for disposal

within each of these facilities.

The camps associated with the construction program will have 20 to 60 people in residence at any one

time. The solid waste generated during maximum occupancy (60 people) will be approximately 1 m3

per

day. There are four camps proposed, two in the northern spread, and two in the southern spread, for an

approximate total of 4 m3

of waste generated per day during peak construction periods.

The solid waste disposal facility at the Town of Inuvik operates under a water licence with the Gwichin

Land and Water Board, and the solid waste disposal facility at the Hamlet of Tuktoyaktuk operates under

a water licence with the NWTWB. The Applicant is currently negotiating an agreement with the

municipalities to receive this waste.

9.1.3 Recyclables and Hazardous Waste

The solid waste generated at the construction camps and equipment maintenance areas will include

minor amounts of hazardous wastes. Hazardous waste types will typically include fuel, lubricants, and

residuals from explosives.

Hazardous waste will be separated from solid waste and stored in ventilated enclosures, in closed-bottom

containers, in accordance with the Waste Management Plan. It will then be packaged, and hauled to

Inuvik for the appropriate treatment and ultimate disposal. The hazardous waste will be either treated and

disposed through a working arrangement with the Town of Inuvik, or transported for disposal via a

licensed carrier and an appropriate manifest to an approved disposal facility outside the NWT.

Recyclable waste will be disposed of through the recycling depot in Inuvik (if the facility is operational).


Section 9: Waste Deposited

June 2013

9-3

9.2 Surface Water Runoff

Sediment dislodged during project activities, such as borrow pit operation or watercourse crossing

construction, has the potential to enter adjacent watercourses or waterbodies.

The operation of the borrow pits for the supply of material for the road construction, as well as the

construction of watercourse crossings has the potential to generate seasonal surface runoff that may

contain sediment. Any runoff containing sediment will be managed in accordance with the project specific

Sediment and Erosion Control Plan (SECP, Appendix E.1).

9.3 Storage of Fuel

Two types of hazardous materials will be used during construction operations:

Fuel and Lubricants

Explosives

Storage and transport of explosives will be authorized under the NWT Explosives Act and any other

applicable legislation. The blasting contractor will be responsible for obtaining and operating in

accordance with applicable legislation.

9.3.1 Fuel and Lubricants

The management of the fuel and lubricants will include the winter and summer transportation of fuel and

lubricants to storage facilities at the borrow sites and strategic sites along the all-weather highway. The

fuel and lubricants will be transported along the winter roads, ice roads and constructed embankment by

fuel transport vehicles operated by qualified drivers. The fuel will be stored in approved storage tanks,

with appropriate secondary containment. The lubricants will be stored in sheltered facilities with

secondary containment. Lubricants that are waste material from oil changes and related activities will be

managed as hazardous wastes.

Fuel and lubricant transportation, storage, and application activities will be executed with the application

of the appropriate regulations, including approved procedures for packaging and handling during

transportation, approved containers (tanks and secondary containment for storage), and approved

application procedures.

Fuel storage areas will need to be constructed at each camp location or at equipment and materials

staging areas. Diesel and gasoline will be required to support construction operations. Exact fuel amounts

and types are not yet known, but it is estimated that each fuel storage locations may require capacity to

store up to 150 m3

(150,000 litres) of diesel and 5 m3

(5,000 litres) of gasoline.

Plans for the handling petroleum products, fuelling equipment, and responding to spills have been

developed or are currently being developed (Appendix E).

Water Licence Application for Construction of Inuvik - Tuktoyaktuk HighwaySubmission to the Northwest Territories Water BoardSection 9: Waste Deposited

June 2013

9-4

9.3.2 Explosives

The operation of the borrow pits will require the use of explosives as part of the extraction process. ANFO

(or AN/FO, for ammonium nitrate/fuel oil) explosives will be used during borrow pit operations. Explosives

will be managed in accordance with the Guidelines for the Use of Explosives In or Near Canadian

Fisheries Waters (DFO 1998). The storage and transport of ANFO will be permitted pursuant to

applicable legislation.

Blasting will be done at times when the ground is frozen, but in the event that water is encountered,

plastic blast hole liners will be used.

11 COMMUNITY CONSULTATION

11.1 Summary of Public Involvement

The ITH project recently completed an environmental review by a substituted panel review process

pursuant to the Inuvialuit Final Agreement and the Canadian Environmental Assessment Act. This

process was open to the public, and several interested parties engaged in the process during the

information request, technical hearings, and public hearing stages of the process.

Consultation was held with co-management agencies (e.g., Wildlife Management Advisory Council,

Fisheries Joint Management Committee, Inuvialuit Games Council, Tuktoyaktuk-Inuvik Work Group),

municipal councils, community corporations, hunter and trapper committees, and/or with the public on

several aspects of the ITH project, including traditional knowledge and traditional land use (February

2012), wildlife and fish protection (September, October and November 2012), and watercourse crossings

(September 2012).

Consultation regarding geotechnical investigations of the borrow sources listed in Table 4-4, was

undertaken as part of the Environmental Impact Screening Committee’s review of Inuvik – Tuktoyaktuk

2013-2014 Geotechnical Investigations Program (EISC File No. 12/12-01). During this consultation, the

GNWT-DOT made it clear that the objective for investigating these borrow sources were for further

consideration for use during construction of the ITH project.

Water licence-related consultation was also conducted with the Tuktoyaktuk Hunter and Trapper

Committee in June 2013 to discuss camp site and water withdrawal locations. A copy of this presentation

is provided in Appendix F. Additional consultation with the Inuvik Hunter and Trapper Committee is

scheduled for June 17, 2013. Consultation records for these meetings will be provided by June 20, 2013.

Project plans will be adjusted as required to respond to concerns raised about locations of camps, use of

specific water sources or other aspects of construction.

11.2 Summary of Issues and Concerns

On January 25, 2013 the Environmental Impact Review Board (EIRB) released its Final Report for the

Environmental Impact Review of the ITH project (EIRB 2013) – the “Report of EIR”. The Report of EIR

made 51 recommendations it deemed necessary to mitigate the adverse environmental and socio-

economic effects of the project (Appendix G).

On April 5, 2013 the Government of Canada responded to the EIRB’s report, as required by the Canadian

Environmental Assessment Act. The Government of Canada “accepted”, “accepted the intent” of, or

“rejected” each of the 51 recommendations (Government of Canada 2013, Appendix H).

environmental management and protection, benefits and collaboration, project construction and

operation, project design and ongoing monitoring. A complete list of Applicant commitments is provided in

Appendix I.


Section 12: Environmental Overview

June 2013

12-1

12 ENVIRONMENTAL OVERVIEW

12.1 Terrain, Soils and Permafrost

The ITH project area spans two distinct Ecoregions: the Mackenzie Delta and the Tuktoyaktuk Coastal

Plain (Ecosystem Classification Group 2007). The Mackenzie Delta Ecoregion is part of the Taiga Plain

Ecozone and consists of the southern two-thirds portion of the Mackenzie River Delta. Typical terrain

along the Delta consists of low-lying fluvial and marine deltaic deposits characterized by a complex

network of small lakes and interconnected fluvial channels. North and east of the Mackenzie Delta is the

Tuktoyaktuk Coastal Plain. Part of the Southern Arctic Ecozone, the Tuktoyaktuk Coastal Plain includes

active portion of the Mackenzie River delta as well as uplands areas characterized by older glacial and

marine deltaic sediments.

More specifically, the terrain along the ITH project area consist of rolling to gently undulating landscape

characterized by glacial and post glacial deposits. Undulating till, hummocky outwash deposits and

extensive lacustrine plains modified by thermokarst and other periglacial processes are the most common

types of deposit. Alluvial and colluvial deposits are found overlying glacial deposits in several areas.

These materials are deposited by streams and gravity related processes and are found along

watercourses and moderate to steep slopes. Very poorly-drained peat-covered areas are extensive in

topographic lows and at proximity to small water bodies. Detailed terrain and surficial material

characterization and mapping in the project area was undertaken by KAVIK-STANTEC in 2012 (KAVIK-

STANTEC 2012b, 2012c, 2012d).The region is underlain by continuous permafrost with sediments often

containing excess ice in the form of ice veins, lenses, wedges, and massive ice (Rampton 1988).

Permafrost related landforms are present throughout the area as represented by extensive polygonal

networks and unique landforms such as pingos. The depth of the active layer (i.e. the portion of soil that

thaws seasonally) varies greatly in relation with the type of material and local site conditions (i.e.,

drainage, water content, micro-topography, etc.). Work from Tarnocai et al. (2004) in the Inuvik –

Tuktoyaktuk area indicates that active layer range anywhere from 30 cm to over 150 cm.

Organic and Turbic Cryosols developed on level to rolling organic, morainal, alluvial, glaciofluvial, and

marine deposits are the dominant soils of the Ecoregion. Areas where permafrost is found within one

metre of the surface, Brunisolic, Regosolic or Gleysolic Static Cryosols have developed. Wetlands are

typically composed of moderately decomposed fen peat, and polygonal peat bogs.

12.2 Hydrology and Water Quality

The study area includes three separate drainage areas (Figure 12-1) within two watersheds (Figure 12-2).

Most of the study area drains into Husky Lakes (Figure 12-1). Less than 10% of the study area drains into

the Mackenzie River primarily in the vicinity of Inuvik. The most northerly portion of the study area drains

into Kugmallit Bay and Tuktoyaktuk Harbour. Surface hydrology in the study area is influenced by long

cold winters, short cool summers and relatively low precipitation (IOL et al. 2004). Low terrain also

influences the hydrology causing the formation of diffuse drainage patterns. There are many shallow

lakes and ponds throughout the study area, as well as deeper larger lakes such as Husky Lakes,

Parsons, Noell and Jimmy lakes. Lakes are generally connected to other lakes or large drainage systems

by small creeks.

Permafrost in the study area restricts the amount of subsurface drainage. As a result, most spring runoff

drains to nearby wetland and lake complexes. However, in areas of predominantly peat and inter-

hummock channels, subsurface runoff into streams can also be important (Quinton and Marsh 1999).

Most of the smaller shallow lakes, ponds, and streams freeze to, or near to the bottom during the winter

period. Larger streams such as Zed Creek and Hans Creek may not freeze to the bottom and maintain

running water throughout the year (IMG-Golder 2012a).

Salts originating from the Beaufort Sea and transported by the air result in chlorine and sodium ions being

the dominant ions found in lakes on the Tuktoyaktuk Peninsula. Lakes have low levels of inorganic

nitrogen and inorganic phosphorus. Generally, there is a decline of nutrients in lakes located north of the

treeline compared to those in the tree line transition zone, except where local thaw-related failures have

directly impacted tundra lakes (Kokelj et al. 2009). Organically bound nutrients are closely associated with

vegetational and climatic zones (Pienitz et al. 1997). Total metal concentrations in the Lower Mackenzie

sub-basin, in which the study area is within, are typically lower than guideline levels for aquatic health and

drinking water but seasonally high levels can occur with increased discharge and suspended sediment

loads as occurs during spring run-off (Kiggiak-EBA 2011).

12.3 Fish and Fish Habitat

The fish fauna for the study area is represented by eight freshwater families of which the Salmonidae

family, including whitefish, is the most diverse and abundant. Families and species common to the area

are listed in Table 12-1. Some marine or estuarine species will move up streams short distances and can

be found at the mouths of creeks especially those draining into Kugmallit Bay or Husky Lakes during the

open water season. These species include fourhorn sculpin, rainbow smelt, starry flounder and arctic

flounder (Rescan 1999).

Table 12-1 List of Common Freshwater Fish found in the Project Area (modified fromRescan 1999)

Family Species Common Name

Esocidae Esox Lucius Northern pike

Osmeridae Hypomesus olidus Pond smelt

Salmonidae Coregonus autumnalis Arctic cisco (herring)

C. sardinella Least cisco (big-eye herring)

C. clupeaformis Lake whitefish (humpack)

C. nasus Broad whitefish (whitefish)

Prosopium cylindraceum Round whitefish

Salvelinus namaycush Lake trout

Stenodus leucichthys Inconnu (coney)

Thymallus arcticus Arctic grayling

Cyprinidae unidentified Unidentified minnows

Catostomidae Catostomus catostomus Longnose sucker

Gadidae Lota lota Burbot (loche)

Gasterosteidae Pungitius pungitius Ninespine stickleback

Cottidae Cottus cognatus Slimy sculpin

Important lakes for fisheries in the ITH project area include Noell Lake, Jimmy Lake, Parsons Lake and

Husky Lakes. Noell Lake supports Arctic grayling and lake trout populations (Rescan 1999), as well as

lake and broad whitefish (ICC et al. 2006). Jimmy Lake receives the outflow of Noell Lake and drains into

Husky Lakes via Stanley Creek. Jimmy Lake supports at least seven species of fish including Arctic

grayling, lake trout and northern pike. Broad whitefish are also present in Jimmy Lake and it has been

speculated that these whitefish utilize the lake as a nursery and have migrated to Jimmy Lake via the

creek system from Husky Lakes (Rescan 1999).

Water Licence Application for Construction of Inuvik - Tuktoyaktuk HighwaySubmission to the Northwest Territories Water BoardSection 12: Environmental Overview

June 2013

12-8

Parsons Lake supports at least 10 species of fish (Rescan 1999). Harvested species include Arctic

grayling, northern pike, lake trout, broad and lake whitefish and Arctic cisco. Zed Creek connects Parsons

Lake with Husky Lakes and allows fish passage between both lake systems. Husky Lakes consists of a

series of five interconnected basins which eventually drain into Liverpool Bay. During fish surveys in 2002

(Harwood 2003), 12 species of fish were captured including both freshwater and marine species (species

tolerant of brackish water). Fish species include lake trout, broad and lake whitefish, Arctic and least

ciscoes, inconnu, Arctic grayling, northern pike, starry and Arctic flounders, Pacific herring, saffron cod.

Fourhorn sculpin are also present in Husky Lakes.

Creeks such as Hans Creek, Zed Creek and Jimmy Creek provide habitat and migratory corridors for a

variety of species including lake whitefish, round whitefish, lake trout, Arctic grayling, ninespine

stickleback and slimy sculpin (Rescan 1999). Northern pike and burbot may also occur in these creeks

(IOL et al. 2004). There is suitable spawning habitat for Arctic grayling in both Hans and Zed Creek (IMG-

Golder 2011).

Most creeks in the study area will freeze to or near the bottom preventing the use of these systems by

fish during the winter period however community harvesters have reported that now some creeks no

longer freeze to the bottom, such as a creek into Noell Lake and some creeks in the Parsons Lake area

(ICC et al. 2006). There is sufficient water depth and flow in Hans Creek and Zed Creek to suggest the

potential for these creeks to provide overwintering fish habitat (IMG-Golder 2011).

For creeks and lakes (e.g., Keneksek and Canyanek systems) which drain into Kugmallit Bay the

shallower lakes may be used by different fish species for rearing and feeding. Deeper lakes may also be

used for overwintering. The streams connecting these lakes are mainly used for migrating between the

lakes and the ocean. Large upstream and downstream runs of broad and lake whitefish, and least cisco

can occur in these streams as fish either try to move up to the lakes to feed, rear, overwinter or move

down to return back to the ocean or Mackenzie River system (Chang-Kue and Jessop 1992; Bond and

Erickson 1987).


Section 13: Predicted Environmental Impacts of Undertaking and Proposed Mitigation

June 2013

13 PREDICTED ENVIRONMENTAL IMPACTS OF UNDERTAKINGAND PROPOSED MITIGATION

13.1 Overview

This section describes the potential effects of ITH project activities on Valued Components (VCs),

identifies mitigation measures to reduce, control or eliminate the effects, and presents the implications of

residual effects.

The ITH project, as an Industrial Undertaking defined in the Northwest Territories Waters Regulations, will

require a water license for the following activities:

Construction of a structure across a watercourse 5 or more metres wide at ordinary high water mark at

point of construction

Watercourse training (culverts)

Use of 300 or more cubic metres per day of water

In addition, there may be an indirect deposit of waste to surface water in conjunction with quarrying above

ordinary high water mark.

Project activities related to water licence requirements include:

Watercourse crossings

Water withdrawal for winter road construction and camp use

Waste management

Storage and handling of petroleum products

Potential environmental effects associated with these activities were identified through community

consultation, a review of the previous environmental assessment and screenings conducted for the ITH

project, and a review of scientific literature, maps, the Inuvialuit CCPs (ICCP 2008, TCCP 2008) and the

Inuvialuit Harvest Study (Joint Secretariat 2003).

The scope of development related to this water licence application that was included in the Panel’s review

(EIRB 2013) is as follows:

Temporary construction camp facilities located at the borrow source closer to the construction activities

Temporary winter access road that is parallel to the permanent alignment during construction

Temporary winter access roads to the borrow sources during construction

Watercourse crossing structures

Water Licence Application for Construction of Inuvik - Tuktoyaktuk HighwaySubmission to the Northwest Territories Water BoardSection 13: Predicted Environmental Impacts of Undertaking and Proposed Mitigation

June 2013

13-2

The ITH project has undergone an environmental review by a substituted panel review process pursuant

to the Inuvialuit Final Agreement and the Canadian Environmental Assessment Act.

The proposed activities are consistent with those reviewed by the EIRB. All borrow sources will be

operated consistent with the Developer’s Commitments (Appendix I) and in response to the EIRB’s

relevant recommendations (Appendix G). Winter roads will be constructed in the same direction as, and

within 1 km of, (parallel to) the alignment to be constructed. Camp facilities will be located at borrow

sources.

13.2 Spatial and Temporal Scope

The spatial scope of the ITH project is evaluated at the following three scales: Project Footprint, Project

Area and Regional Area. The Project Footprint includes the highway embankment, winter and ice roads,

borrow sources, water sources, and camp areas. The Project Area includes a 1 km buffer extending from

Project Footprint boundaries. The Regional Area includes a 15 km buffer extending from Project Footprint

boundaries, and the seasonal range of each VC has been included in the assessment.

The temporal scope of the ITH project is limited to December 2013 (Year 1) to September 2017 (Year 4),

as discussed in Section 4.3: Proposed Time Schedule.

13.3 Valued Components

A Valued Component (VC) is defined as an environmental, social, economic or cultural component that is

considered important by the proponent, local communities, technical specialists and/or government. The

assessment of ITH project effects on VCs provides an indication of ITH project effects on broader

environmental and social conditions. Similarly, mitigation measures for ITH project effects on VCs provide

protection for the broader environmental and social systems they represent.

Candidate VCs in relation to the ITH project were selected based on:

Sensitivity to project effects

Importance to local communities and resource users

Territorial, national or international importance (including status under the SARA)

Value as an indicator of effects on related resources and broader systems

Candidate VCs were identified for the ITH project based on the environmental overview and community

consultation. Candidate VCs were screened to select final VCs based on their potential to be affected by

ITH project activities. In this study, candidate VCs were excluded if they did not overlap temporally or

spatially with the ITH project, or if there is no, or negligible, potential for the ITH project to affect them.

Selected VCs and the rationale for selection are provided in Table 13-1. The selected VCs are the subject

of further assessment and mitigation planning in Section 13.5.

Table 13-1 Candidate and Selected Valued Components in the Project Area andRationale for Selection

Candidate VC Selection Rationale

Terrain, Soil and Permafrost Potential for ground disturbance during construction activities

Soil will be disturbed during borrow source activities

Water Quantity (Hydrology) Drainage patterns may be affected by the use of snow fills at creek crossings

Water withdrawal may affect lake water levels

Water Quality Water quality may be affected by accidental degradation of lake and creek banksand improper fill materials at lake and creek crossing locations

Water quality may be affected in the case of an accidental spill or discharge

Fish and Fish Habitat Fish and fish habitat may be affected through water withdrawal reducing or alteringviable fish habitat

Fish may be entrained or impinged by the water intake

Fish migration may be delayed or blocked due to snowfills used in watercourses

Improper fill materials at creek and lake crossings or cutting of banks may lead tosedimentation of watercourses or waterbodies potentially affecting fish habitat andfish health

Accidental fuel spills could have health effects or cause tainting of fish

Muskrat and Beaver Potential for push ups and dens to be disturbed by winter road construction andoperation

Waterbirds and Waterfowl Potential for changes to water quality from project activities

Harvesting and TraditionalLand Use

The winter and ice roads will provide access to subsistence fishing and harvestingareas

Lakes are an important subsistence fish harvest source

Larger watercourses may be used for transportation

13.5 Impact Assessment and Mitigation

The Applicant has developed many mitigation measures and commitments during the environmental

review process. This has resulted in the Substituted Panel determining that “it will cause impacts on the

environment”, but that “the potential adverse effects of the ITH project can be mitigated and properly

managed if the Panel’s recommendations and the Developer’s commitments are implemented” (EIRB

2013, p. iii). The Government of Canada (2013, p. 5) stated that “taking into consideration the Panel

Report and the implementation of mitigation measures that are considered appropriate, the Government

of Canada has determined that the ITH project is not likely to cause significant adverse environmental

effects.” The Applicant/Developer Commitments are included in Appendix I.

Potential environmental effects and corresponding mitigation measures are identified in Table 13-3. The

mitigation measures will be implemented for the duration of ITH project construction activities.

13.6 Residual Effects of the Project on the Environment

13.6.1 Assessment of Residual Environmental Effects

As discussed in Section 13.5, the Substituted Panel reviewed the ITH project’s environmental effects and

determined that “it will cause impacts on the environment”, but that “the potential adverse effects of the

ITH project can be mitigated and properly managed if the Panel’s recommendations and the Developer’s

commitments are implemented” (EIRB 2013, p. iii). The Government of Canada (2013, p. 5) stated that

“taking into consideration the Panel Report and the implementation of mitigation measures that are

considered appropriate, the Government of Canada has determined that the ITH project is not likely to

cause significant adverse environmental effects.” The Government of Canada responded to the EIRB’s

recommendations by “accepting”, “accepting the intent of” or “rejecting” each of the recommendations.

Residual environmental effects are those effects to environmental components which remain after the

application of mitigation. The mitigation to be applied has been summarized in Table 13-3.

13.6.2 Terrain, Soils and Permafrost

To mitigate residual effects to terrain, soil and permafrost, the EIRB (2013) recommended that:

R36: AANDC and the NWT Water Board shall ensure that the same road alignments are not used to

access aggregate sources every year in order to avoid the vegetation and terrain damage caused by

repeated use.

R37: The Developer shall develop a monitoring program with respect to vegetation and terrain that

includes active layer and near-surface permafrost impacts from winter road construction to the

aggregate sources. Monitoring reports should be filed with the appropriate regulators, including

AANDC, on a regular basis and not less that every two years, with particular emphasis on cumulative

impacts of the roads on these terrain characteristics. This monitoring program and its results shall be

integrated into the cumulative effects and adaptive management programs to be established by the

IEMOC.

The Government of Canada’s responses to the EIRB’s recommendations are as follows:

R36: The Government of Canada accepts the intent of this recommendation and notes that it is

directed at AANDC and the Northwest Territories Water Board. The Government of Canada

understands the intent of this recommendation is to reduce the damage to vegetation and terrain from

repeated use of winter access roads. AANDC, as a regulator of land-use activities, has the ability to

manage this activity on a case-by-case basis, and will work with the Northwest Territories Water Board

and the Developer to ensure the appropriate management of winter road alignment.

R37: The Government of Canada notes that this recommendation is directed at the Developer and

accepts its intent. The Government of Canada agrees with the need for monitoring reports to be

provided to the regulators, consistent with legislative and regulatory requirements, and will work with

the Developer to determine the appropriate scope of a monitoring program with respect to vegetation

and terrain.


June 2013

13-12

13.6.3 Water Quantity (Surface Water)

To mitigate residual effects to water quantity, the EIRB (2013) recommended that:

R34: The 10 per cent water withdrawal limit contained in the DFO Protocol for Winter Water

Withdrawal from Ice-covered Waterbodies in the Northwest Territories and Nunavut (2010) shall be

applied to every lake and water body used as a water source over the lifetime of the Project.

R35: Monitoring of the effects of long term water use for the construction of these roads shall be

included in the regulatory approvals granted by DFO, AANDC and the NWT Water Board, as

appropriate, and the results of this monitoring shall be integrated into the cumulative effects and

adaptive management programs to be established by the IEMOC.


R34: The Government of Canada accepts this recommendation. The Developer has committed to

using DFO’s “Protocol for Winter Water Withdrawal from Ice-Covered Waterbodies in the Northwest

Territories” and other relevant guidelines. The Government of Canada notes that detailed information

is not required for all waterbodies according to the protocol; however, location and quantities being

withdrawn would still be required for each water source to determine compliance. This information

requirement will be addressed through the Northwest Territories Water Board process.

R35: The Government of Canada accepts the intent of this recommendation. Currently, there is no

program in place for the monitoring of long term water use; however, DFO will work with other parties

as appropriate, including AANDC and the Northwest Territories Water Board, to ensure that impacts

from water use are avoided and by providing expert advice in the development of monitoring plans,

coordinating monitoring efforts and sharing of information.

13.6.4 Water Quality

Potential water quality effects were identified by the EIRB in relation to fish and fish habitat. As such,

those recommendations are provided in Section 13.6.5.

13.6.5 Fish and Fish Habitat

To mitigate residual effects to fish and fish habitat, the EIRB (2013) recommended that:

R29: The Developer shall consult with both DFO and AANDC to determine appropriate mitigation

measures before using a chemical dust suppressant technique on the ITH.

R30: The Developer shall, prior to construction, develop management plans for the protection of fish

and fish habitat in any areas affected by construction in collaboration with DFO, and the Tuktoyaktuk

and Inuvik HTCs and FJMC.

R29: The Government of Canada accepts the intent of this recommendation and notes that it is

directed at the Developer. The Government of Canada supports the need to manage the use of

chemical dust suppressants and would like to note that EC, TC, DFO, AANDC and the Northwest

Territories Water Board have overlapping jurisdiction with respect to the management of this matter.

The Developer shall consult with these departments to determine appropriate mitigation measures

before using a chemical dust suppressant techniques on the Project. The Government of Canada will

work with the Developer and other appropriate parties to promote compliance with relevant legislation

and to provide advice on proposed mitigation measures related to chemical dust suppressant

techniques.


accepts its intent. As a participant in the co-management structure set out in the Inuvialuit Final

Agreement, DFO will continue to work with the Fisheries Joint Management Council and Hunters and

Trappers Committees on the management of fisheries resources in the Inuvialuit Settlement Region.

DFO will ensure that the mitigation measures as well as monitoring and management plans required

under any potential Fisheries Act authorizations are met through standard compliance monitoring and

enforcement.


accepts its intent. DFO will work with the Developer with respect to crossing design details, fish habitat

compensation, mitigation measures and monitoring to address the information requirements necessary

to make a regulatory decision and issue potential authorizations under paragraph 35(2)(b) of the

Fisheries Act. If the crossings are properly designed, long-term maintenance to protect fish and fish

habitat may not be required.

13.6.6 Muskrat and Beaver

To mitigate residual effects to muskrat, the EIRB (2013) recommended that:

R25: The Developer shall complete pre-construction surveys for muskrat push-ups on lakes where

winter snow removal and/or winter water withdrawal will take place.

R26: The Developer shall follow mitigation measures set out in permits issued under the Wildlife Act

and monitor mitigation success, if muskrats are present.


R25: The Government of Canada notes that this recommendation is directed at the Developer. The

Government of Canada accepts the intent of the recommendation and will work with the Developer

and appropriate parties, as required, to ensure its implementation.


Government of Canada accepts the intent of the recommendation and will work with the Developer

and appropriate parties, as required, to ensure its implementation.


June 2013

No recommendations were made by the EIRB related to beavers.

13.6.7 Waterbirds and Waterfowl

Potential water quality effects were identified by the EIRB in relation to species at risk. To mitigate

residual effects to waterbirds and waterfowl, the EIRB (2013) recommended that:

R32: The IEMOC shall determine appropriate setback distances for… critical habitat of SAR, waterfowl

and tundra-nesting bird species.

The Government of Canada’s responses to the EIRB’s recommendations (relevant to bird species) are as

follows:

R32: The Government of Canada accepts the intent of this recommendation. The Government of

Canada expects the Developer to work with parties to determine appropriate setback distances for …

nests of bird species at risk, waterfowl and other tundra-nesting bird species under the umbrella of the

follow-up program and through the development of the WEMP. The Government of Canada notes that

regulatory authorities may have the ultimate discretion to determine setbacks where they may be

included as conditions in permits or authorizations issued for the Project. The Government of Canada

would also like to clarify that critical habitat as defined in the federal Species at Risk Act has not been

identified for any of the species at risk that may occur in the area proposed for development of the

Project…The Government of Canada will work with the appropriate parties to meet the intent of this

recommendation, as required.

13.6.8 Harvesting and Traditional Land Use

To mitigate residual effects to harvesting and traditional land use, the EIRB (2013) recommended that:

R20: The Developer shall work with the Parties (DFO, EC, ENR) and comanagement bodies (FJMC,

WMAC) and HTCs to ensure that the Developer’s mitigation, monitoring and management

commitments related to wildlife, fish and harvesting are met and reported on annually through IEMOC

or through the specific comanagement bodies responsible for resource management in the ISR.

R50: The Inuvialuit Land Administration shall work with the Developer, HTCs, FJMC and WMAC

(NWT) to ensure proper signage and guidelines are established to monitor access to the Husky Lakes

area.

R51: Developer shall consult with the communities, HTC's and ISR comanagement boards on the

development and content of the Project's environmental management plans in relation to Category E

lands.

Government of Canada accepts the intent of the recommendation and modifies it such that the results

of monitoring would be met and reported on through a combination of regulatory instruments, the

follow-up program and specific co-management bodies responsible for resource management in the

Inuvialuit Settlement Region. DFO will continue to work closely with co-management bodies such as

the Fisheries Joint Management Committee and the Tuktoyaktuk to Inuvik working group to manage

fisheries resources in the Inuvialuit Settlement Region. DFO will ensure that the mitigation measures

as well as monitoring and management plans required under any potential Fisheries Act authorizations

are met through standard compliance monitoring and enforcement. Environment Canada will continue

to work closely with co-management bodies such as the Wildlife Management Advisory Council to

manage wildlife resources within their departmental mandate. The Government of Canada will work

with other appropriate parties, as required, to monitor implementation of the Developer’s commitments

related to mitigation, monitoring and management for wildlife, fish and harvesting.

R50: The Government of Canada notes that this recommendation is directed at the Inuvialuit Land

Administration.


accepts its intent.

13.7 Assessment of Residual Environmental Effects

With the application of the mitigation measures (Table 13-3), the Developer Commitments (Appendix I),

the EIRB’s recommendations (Appendix G), and the Government of Canada’s recommendations

(Appendix H) residual effects to the VCs will be prevented or mitigated.

Additional monitoring and consultation requirements not included in Developer Commitments and not

otherwise required as part of regulatory approvals are summarized in Table 13-4:

13.8 Effects of Accidents and Malfunctions

The following section states the findings of the EIRB (2013, p. 145-147).

The potential exists for accidents or malfunctions to occur in association with any human activity,

including those proposed for the construction of the ITH. Environmental consequences of potential

accidents or malfunctions related to the ITH project and associated aggregate borrow and construction

camp activities would be primarily limited to those related to vehicle crashes and fuel storage,

transportation and handling system failures.

The Developer has proposed to employ a number of preventative and mitigation measures to minimize

environmental effects of malfunctions or accidents that may occur in connection with the project. Their

key strategy will be to prevent accidents and malfunctions through education, monitoring, follow-up and

enforcement. With the application and implementation of preventative and mitigation measures, the

Developer anticipates no significant fuel, chemical or other product spills are expected to occur.

These measures include:

implementation of best management and industry practices to prevent or minimize the occurrence of

accidents or malfunctions;

ensuring that all on-site contractors have industry-compliant and satisfactory Health, Safety and

Environmental (HSE) policies, programs and manuals and that they are successfully implemented

throughout the project;

ensuring that the Developer and its contractors have an environmental management plan and spill

contingency plan that will address potential accidents and malfunctions for the life of the project. In

particular, the Developer will ensure that a spill contingency plan is in place that conforms to INAC’s

(2007) Guidelines for Spill Contingency Planning. In particular, the plan will include:

descriptions of the type and amount of contaminants stored at the project location;

site map of the location;



June 2013

13-17

steps to be taken to report, contain, clean-up and dispose of contaminants in the case of a spill;

a description of the training provided to employees to respond to a spill; and

an inventory of and the location of response and clean-up equipment available to implement the

spill contingency plan.

compliance with the terms and conditions of the necessary Inuvialuit Land Administration and

AANDC’s land use and quarry permits and authorizations that will be issued for the construction

project;

conformance with existing applicable GNWT and Workers Compensation Board standards;

fuel and other hydrocarbons will be stored in accordance with Canadian Council of Ministers of the

Environment (CCME’s) (2003) Environmental Code of Practice for Aboveground and Underground

Storage Tank Systems Containing Petroleum and Allied Petroleum Products, INAC’s (2011b) Northern

Land Use Guidelines: Camp and Support Facilities, and to the extent applicable, and the Canadian

Environmental Protection Act (CEPA) Storage Tank System for Petroleum Products and Allied

Petroleum Products Regulations.

all vehicles and equipment will be re-fuelled at least 100 m from water bodies following INAC’s (2011b)

Northern Land Use Guidelines: Camp and Support Facilities; and,

spills will be reported to the 24-hour Spill Report Line.

The project construction team will work closely with the ILA environmental and wildlife monitors when the

proposed ITH is being constructed.

The Developer and its contractors are expected to generate hazardous wastes. DOT is currently a

registered generator of hazardous waste and is directly responsible for the hazardous waste generated

from their operations. Further, DOT is indirectly responsible for the hazardous waste generated from

private contractors on the project. The Developer is aware that hazardous waste must be disposed of at

an approved facility, and that it is not appropriate to dispose of hazardous waste in NWT community solid

waste facilities.

To mitigate potential adverse environmental effects associated with improper hazardous waste disposal

and to further demonstrate that proper hazardous waste management planning is in place, the Developer

has committed to the development of a hazardous waste management plan (HWMP) that will encompass

all pre-construction and construction phases of the project and will apply to the Developer and all

contractors involved in receiving, transferring, and transporting hazardous waste for the Developer’s

activities on land, water, and air.

The HWMP will include, but not be limited to:

identifying hazardous waste sources, types, and approximate quantities to be produced, including

liquid, solid, dangerous goods and non-dangerous goods;

describing waste segregation methods;


June 2013

13-18

describing all on-site treatment and disposal methods; and,

describing hazardous wastes that will be transported to approved receiving facilities.

Safety measures to prevent vehicle accidents on the proposed ITH have been and will continue to be

incorporated into the ITH design by the Developer. Measures to avoid or minimize accidents will include

posted speed limits and adequate signage alerting drivers to highway curves and upcoming bridges.

Bridge design will incorporate guardrails to prevent a vehicle from going off the bridge and into a

watercourse in the event of an accident.

With respect to environmental effects, a worst case would involve environmental damage to the Husky

Lakes and effects to traditional activities and harvesting as a result of a fuel supply truck crash or rollover

on the ITH, in a location nearest the Husky Lakes (e.g., km 80) and which causes a fuel spill of greater

than 10,000 L into an open watercourse that is a direct tributary to the Husky Lakes. This scenario is

discussed under section 13 of this report.

The Panel accepts the Developer’s evidence on accidents and malfunctions.

13.9 Proposed Monitoring Programs

Monitoring plans that will be implemented during the ITH project to verify the effectiveness of mitigation

measures are as follows:

Wildlife Effects Monitoring Plan (Developer Commitment, Appendix I)

Aquatic Effects Monitoring Plan (EIRB R35)

Terrain, Vegetation and Permafrost Monitoring Plan (if needed) (EIRB R37)

Compliance Monitoring Plan (Developer Commitment, Appendix I)

13.10 Cumulative Effects

No new projects have been proposed in the region since the Substituted Panel’s review. The Panel’s

analysis of the cumulative effects resulted in recommendations for ongoing monitoring. EIRB (2013,

p. 137-141) recommendations are as follows:

R46: The Developer, in collaboration with GNWT-ENR, EC and wildlife comanagement organizations,

working through the IEMOC [Independent Environmental Monitoring and Oversight Committee], shall

further develop and implement the proposed WEMP to ensure that it addresses both direct and

cumulative effects from highway construction and operations on wildlife distribution and abundance

within the regional cumulative effects study area.

R47: The results of WEMP monitoring of cumulative effects on wildlife, vegetation and land use shall

be integrated into the IEMOC’s adaptive management framework, and, to the extent possible, into any

government regional cumulative effects monitoring programs.



June 2013

13-19



accepts its intent. The recommendation requires the Developer to collaborate with Government of

Northwest Territories Department of Environment and Natural Resources, Environment Canada and

wildlife co-management organizations. The Government of Canada believes that the WEMP can be

developed and implemented as part of the follow-up program in such a way that it addresses direct

effects from construction and operations on wildlife distribution and abundance and can contribute

towards broader cumulative effects monitoring within the regional cumulative effects study area. The

Government of Canada will work with the appropriate parties, as required, to ensure that the

development and implementation of the WEMP meets the intent of this recommendation.

R47: The Government of Canada accepts the intent of this recommendation. However, the

Government of Canada believes that the results of the WEMP monitoring of project-specific effects on

wildlife, vegetation and land use could be integrated into an adaptive management framework formed

under the umbrella of the follow-up program. The Government of Canada will work with the appropriate

parties, as required, to ensure the results of the project-specific WEMP are integrated into any

government regional cumulative effects monitoring programs to the extent possible.
