1. Introduction
The Otter Creek Wind Farm (the Project) is being proposed by Otter Creek Wind Farm Limited Partnership (Otter
Creek), a partnership of Renewable Energy Systems Canada (RES Canada) and Boralex Inc. In close proximity to
the Project is Walpole Island First Nation who is a participant of this project. The Project is also grateful to have
received support from the Municipality of Chatham-Kent which has been granted an option to participate in the
Project.
The Project has been proposed in response to the Government of Ontario’s plan to integrate more renewable
energy into the province’s power grid. This Site Investigation Report was prepared in accordance with the
requirements of the Renewable Energy Approval (REA) process outlined in Ontario Regulation (O. Reg.) 359/09,
as amended, and the Natural Heritage Assessment Guide for Renewable Energy Projects (MNRF, 2012).
The Project’s nameplate capacity is up to 50 megawatts (MW) and the wind farm will consist of up to 12 turbines.
The proposed turbine for the Project is the Enercon E-141 with a nameplate capacity of up to 4.2 MW. With a
nameplate capacity of up to 50 MW, the Project is categorized as a Class 4 wind facility and will be in compliance
with the requirements outlined for such facilities.
Project Boundary and Location 1.1
Otter Creek is proposing to develop a wind energy project located north of the community of Wallaceburg in the
Municipality of Chatham-Kent, Ontario. The location of the Project was determined based on interest expressed by
local landowners, municipal support for the Project, the availability of wind resources, and the availability of existing
infrastructure to facilitate a connection to the electrical grid.
The Project Boundary is generally bounded by Whitebread Line and Kent Line to the north, Payne Road to the
west, Stewart Line and McCreary Line to the south and Mandaumin Road / County Road 44 to the east (refer to
Figure 1). The Project Boundary represents the wider area that was considered for the siting of project
infrastructure. The following co-ordinates define corners of the external boundaries of the Project Boundary:
Longitude
(Degrees North)
Latitude
(Degrees West)
-82.468736 42.631227
-82.245325 42.626739
-82.246385 42.601952
-82.469707 42.606686
The Project Boundary encompasses approximately 4,600 hectares (11,400 acres1) of land that is predominantly
designated for agricultural use according to the Municipality of Chatham-Kent’s Official Plan (2016) and Zoning By-
law (2015). The Project Boundary also consists of fragmented areas of forest and riparian habitat associated with
the Sydenham River, which bisects the Project flowing in a north-south direction, as well as other small creeks
and/or farm drains.
1. Metric units are used throughout REA documentation when describing the size of Project infrastructure, except in instances describing areas of land. When describing land size, acres (imperial) will be used rather than hectares (metric) because it is the measuring unit most commonly used by the local community. It is assumed that 1 hectare of land is equal to 2.47 acres of land.

According to O. Reg. 359/09, as amended, the Project Location is “a part of land and all or part of any building or
structure in, on, or over which a person is engaging in or proposes to engage in the project and any air space in which
a person is engaging in or proposes to engage in the project”. As described therein, the Project Location boundary is
the outer limit of where site preparation and construction activities will occur (i.e., disturbance areas described below)
and where permanent infrastructure will be located, including the air space occupied by turbine blades.
To provide flexibility while designing and constructing the location of Project infrastructure, only the locations of
turbines and collector lines (including associated infrastructure such as junction boxes) within public RoW have
been identified within the Project Location; therefore, with the exception of turbines and collector lines within the
RoW, the most conservative approach was taken for the purposes of the NHA by assuming that any other type of
infrastructure could be located in the remaining Project Location (Figure 1).
For the purposes of completing this Natural Heritage Assessment, a 50 m Area of Investigation for collector lines
located within Public RoW and a 120 m Area of Investigation for all other infrastructure types were applied to the
Project Location. These distances are based on the requirements of O. Reg. 359/09 and the Natural Heritage
Assessment Guide for Renewable Energy Projects (MNRF, 2012), hereafter referred to as the Natural Heritage
Assessment Guide. The Area of Investigation encompasses the Project Location and an additional 50 m or 120 m
surrounding the Project Location, measured from the Project Location boundary as described above. Going
forward, areas in or within 50 m of the collector lines located within Public RoW (Roadside Collector Project
Location) as well as areas in or within 120 m of turbines (Turbine Project Location) and all other Project
infrastructure (Remaining Project Location) will be referred to as the Area of Investigation. As part of the REA
process, features located within the Area of Investigation must be investigated and evaluated to determine whether
they are significant or provincially significant, in order to ascertain whether development prohibitions apply as per
O. Reg. 359/09 the Natural Heritage Assessment Guide.
This report summarizes the REA requirements with respect to completing an EIS (Section 2) and provides an
overview of the results of the Evaluation of Significance (Section 3), and the proposed Project (Sections 4 and 5)
as described in the Otter Creek Wind Farm Construction Plan Report (AECOM, 2016a). A general overview of the
potential effects of the proposed Project is provided in Sections 6. Details regarding the potential effects,
performance objectives, mitigation measures, monitoring plan and contingency measures for specific natural
features determined to be significant or treated as significant and therefore carried forward to the EIS are described
in Sections 7 and 8. Finally, a brief summary and the overall conclusions of this EIS is provided in Section 9.

2. REA Requirements
Under Section 38 (2) of O. Reg. 359/09, an Environmental Impact Study (EIS) must be conducted for all significant
natural features that are within the Area of Investigation. Under the REA process, the EIS must:
Identify and assess any negative environmental effects of the Project on significant natural features as
a result of construction, operation, or decommissioning of the Project;
Identify appropriate mitigation measures to address any negative environmental effects of the Project
on significant natural features;
Describe how the Environmental Effects Monitoring Plan addresses any negative environmental effects
of the Project on significant natural features; and
Describe how the Construction Plan Report addresses any negative environmental effects of the
Project on significant natural features.
The potential effects and mitigation measures described in this EIS are consistent with the conclusions presented in
the Otter Creek Wind Farm Construction Plan Report (AECOM, 2016a) and the Otter Creek Wind Farm Design and
Operation Report (AECOM, 2016b), as well as the Otter Creek Wind Farm Environmental Effects Monitoring Plan
(AECOM, 2016c).

3. Summary of Evaluation of Significance
In accordance with Section 27 of O. Reg. 359/09, AECOM has conducted an Evaluation of Significance (EOS) for
all potentially significant natural features within the Area of Investigation. The details of these evaluations are
presented in the Otter Creek Wind Farm Evaluation of Significance Report (AECOM, 2016d) and those features
which were carried forward to the EIS are summarized below in Table 3-1.
No part of the proposed Project is located within 120 m of a Provincially Significant Wetland (PSW) or Provincially
Significant Area of Natural or Scientific Interest (ANSI). However, some portions of the Project Location are
proposed within 120 m of significant natural features including Significant Woodlands and Significant Wildlife
Habitat (SWH). Potential negative effects of the Project on these significant natural features are addressed herein.

4. Summary of Project Components
The proposed Project Location is described in detail in the Otter Creek Wind Farm Construction Plan Report
(AECOM, 2016a). Table 4-1 below presents a description of the Project components as described in the Otter
Creek Wind Farm Construction Plan Report (AECOM, 2016a).
Table 4-1: Description of Project Components
Component Description
Wind Turbine
Generators
The Project will include commercial wind turbines with a project total nominal power up to 50MW. The turbine nacelle
includes the electric generator, wind direction and speed sensors and auxiliary equipment. These components are
located at the top of a supporting tower and are connected to three blades and a hub.
Wind Turbine
Foundation
Each turbine tower is anticipated to have a concrete foundation. The land base of each turbine foundation will be
dependent on subsurface conditions determined during geotechnical investigations. Following geotechnical
investigations, it may be determined that spread-footing type foundations may be suitable for certain locations;
otherwise alternative foundation designs will be considered (e.g. Deep foundations).
Collector
Transformers
A collector transformer will be located inside the turbine tower. This transformer ‘steps-up’ the electricity generated by
the wind turbine to a common electrical collector line voltage, likely 34.5 Kilovolts (kV).
Wind Turbine
Access Roads
During construction and operation of the proposed Project, roads are required in order to access wind turbine
locations. Access roads will be constructed within the Project Location and developed to accommodate cranes and
transportation equipment used to deliver wind turbine components.
Collector Lines Collector lines carry the electricity from the collector transformers to the Project electrical substation (described
below). The collector lines will likely be 34.5 kV standard utility generator lines located within the Project Location on
private property and within the public RoW until it reaches the Electrical Substation.
The underground collector lines will be buried in accordance with ESA standards. This depth will likely be deeper
than 0.75 m below ground surface. If aboveground electrical collector lines are required, they will be constructed on
either wood, steel or concrete pole structures.
Where two or more underground collector lines must be connected together, a junction box will be installed either
below or aboveground. Junction boxes may contain equipment related to splices, junctions, cable splices and
disconnect switches. They will be located either on private lands or within the ROW and contained within the CDA.
Where two or more overhead collector lines must be connected together, a junction box may be installed. Junction boxes
may contain equipment related to splices, junctions, cable splices and disconnect switches.
Electrical Substation An electrical substation is required to bring together all of the underground and aboveground electrical collector lines.
The collected power will be transformed from the electrical collector line voltage (34.5 kV) to a transmission voltage
(115 kV).
Electrical substation equipment may include an isolation switch(es), circuit breaker(s), step-up power transformer(s),
distribution switch-gear(s), instrument transformers, capacitor banks, communication equipment which may include a
communication tower, Supervisory Control and Data Acquisition equipment, protection and control equipment,
grounding transformers, grounding grid, revenue metering (conforming to the Independent Electricity Systems
Operator (IESO) market rules), substation grounding, parking and a control building.
A secondary containment system may be installed at the transformer constructed at the substation to prevent soil
contamination in the event of a leak if petroleum products are used within the equipment installed.
Communication
Tower
A Communication tower used for communication purposes may be constructed within the substation Construction
Disturbance Area (CDA) and/or the interconnection station location. If required, the Communication tower may be up
to 100 m tall. Height, soil conditions and space requirements will determine whether the tower will be steel-lattice or
guyed.
Meteorological
Towers
One or more permanent meteorological towers, up to approximately 129 m in height, may be constructed using
cranes and secured with guy wires tied off to anchors.
Access roads may be constructed to access meteorological tower locations and the site may be surrounded by a
chain link fence. The towers will be connected to the Project power and communication infrastructure.
There is a possibility of using the meteorological tower to host communications equipment to serve the purpose of the
communications tower.

Table 4-1: Description of Project Components
Component Description
Interconnection
Station (Connection
to Electrical Grid)
The point of interconnection will require modifications to the existing transmission line and may include circuit
breakers, isolation switches, transmission switchgear, instrumentation, grounding, metering equipment and other
equipment typical of such systems.
There will be an interconnection line from the transformer to the POI.
The interconnection plan for any wind project is subject to study, design, engineering and approval by the IESO which
manages the province’s electricity grid and Hydro One Networks Inc. (Hydro One) which owns the transmission lines.
Operations and
Maintenance
Building
An operations and maintenance building may be constructed. This building may accommodate offices, maintenance
work areas, control facilities and a parking area and will likely be located within the Project Boundary.
An access road to the operations and maintenance building from a municipal or privately owned road would be used
to access the operations and maintenance building during the operation of the Project.
Construction offices and temporary storage of Project equipment may also occur in pre-existing areas used for
commercial, industrial or other purposes.
To facilitate the construction of the proposed Project, a number of temporary construction components are also
required. These temporary components, described further in Table 4-2 below, include turbine working areas and
laydown area(s).
Table 4-2: Description of Temporary Project Components
Component Description
Laydown Areas Approximately 10 to 20 acres of land area may be constructed for the temporary storage of construction
material/equipment/components and as a site(s) for the construction office trailers, staff vehicle parking and other
construction related needs.
Following clearing and grubbing of any vegetation, the topsoil at the temporary laydown area will be removed and a
layer of clean compacted crushed gravel will be imported, as needed.
A temporary electrical service line may be connected to the existing distribution line for the purpose of providing
power to the construction office trailers.
Turbine Working
Area
Temporary working areas will be constructed at the same time as the access roads and will be located adjacent to the
turbine locations.
Crane pads will be constructed in tandem with wind turbine access roads and after topsoil and subsoil are removed
from the areas. The Turbine Working Areas will consist of left over subsoil and may be filled with varying mixtures of
granular base material and/or crushed gravel depending on site specific conditions.
Crane mats will be used to stabilize cranes during their operation.
The total turbine working area will be approximately 2.5 acres.
After the turbine erection is complete, the crane mats, granular base materials and crushed gravel will be removed,
native topsoil replaced, and working areas returned to their pre-construction condition, at the discretion of the
landowners. A small gravel pad will be left in place at the base of the turbine around the turbine foundation for
maintenance truck access and circulation.

5. Description of Construction and Installation Activities
The following sections provide the following information for construction and installation activities:
Project timing;
Materials brought on-site;
Temporary uses of land;
Construction equipment used; and
Explanation of how the components will be constructed.
In general, all work crews will drive automobiles (typically light trucks) to reach the Project Location. Flatbed trucks
will be used to transport specialized equipment (e.g., tracked bulldozers, excavators, loaders, dump trucks,
compactors and graders) to the Project Location. Construction equipment, fuel and lubricants will be delivered to
temporary turbine work areas / laydown areas by large truck and trailer combinations.
Timing of Construction and Installation Activities 5.1
Subject to the receipt of the necessary permits and approvals, site work for the Project is expected to begin in 2018
and last for approximately 8-10 months. Construction and installation activities will likely generally occur at times of
day when agricultural machinery would normally be in operation, unless circumstances require otherwise. Table 5-
1 presents the anticipated construction schedule and approximate order of construction activities for the proposed
Project.

Pre-construction Activities 5.2
5.2.1 Surveying and Geotechnical Sampling Activities
Prior to construction, a registered Ontario Land Surveyor (or equivalent) will survey the Project Location and property
lines. Equipment used for surveying will likely include a small number of light duty trucks and all-terrain vehicles.
Existing buried infrastructure located on public property will be identified using the Ontario One Call service and
buried infrastructure located on private property will be identified by private contractors prior to construction and
updated throughout construction, as required.
Geotechnical sampling will be required for turbine foundation locations, the substation, transmission line poles,
access roads and collector lines. Typically, a truck-mounted drill rig visits the sampling locations, drills the borehole
and collects geotechnical information for laboratory testing and analysis. Information collected will include details of
soil compaction, grain size, resistivity, soil pH, and depth to the collector substation and along collector lines. This
operation typically uses two operators and requires three to four hours per turbine location.
Equipment will include, at a minimum, trucks, a truck mounted drill rig, and possibly a track-mounted drill rig. The
trucks will be driven to the site via existing municipal roads. No materials will be brought on-site for these activities and
any waste generated would be comprised of drill cuttings which will be scattered in the vicinity of the boreholes. The
chemicals required for this phase will include oils, gasoline and grease used to operate construction equipment.
Construction Activities 5.3
The Project Location (or CDA) as defined in Section 1 and depicted in Figure 3, is the area of land within the Project
Boundary that may be used for the construction and operation of the wind farm. The project components, including
those listed in Section 2 of this report may be located anywhere within the Project Location and the following list
includes some of the project activities that may be completed to construct the necessary Project Components:
Land clearing;
Construction of access roads;
Construction of laydown area(s);
Construction of turbine working area(s);
Delivery of equipment;
Construction of wind turbine foundations;
Wind turbine assembly and installation;
Construction of Electrical Collector System;
Construction of Electrical Substation and Interconnection station;
Construction of Operations and Maintenance Building;
Construction of Permanent Meteorological Tower(s) (up to approximately 129 m in height);
Installation of Communication Tower (up to approximately 100 m in height); and
Site clean-up and reclamation.
The following sections describe these potential construction activities in more detail.
5.3.1 Land Clearing
The construction of the access roads will typically require clearing and grubbing of any vegetation, excavation of
the topsoil layer and adding a layer of compacted material. Prior to access road construction, soil from the access
road footprint will be stripped and stockpiled for re-use following construction to reclaim the site.

B1_04_Eis (26.10.2016) 11
5.3.2 Construction of Access Roads
Access roads will be constructed to transport equipment to the construction sites. The construction of the access
roads will result in disturbance areas approximately 20 m wide. The access road will be sited within the Project
Location in consultation with the landowner and taking into consideration potential environmental effects. Where
possible, access roads will be situated to limit impacts to land use and limit the number of watercourse crossings.
As necessary, ditches and culverts will be constructed to maintain existing site drainage. The road structure will be
a geotextile and gravel, or soil stabilized.
New culverts may be required to maintain drainage in ditches at junctions with roadways and these will be
constructed to support the construction equipment and delivery trucks. The details of culverts and their installation
in addition to erosion control measures will be determined in consultation with the St. Clair Region Conservation
Authority (SCRCA) and/or the Municipality of Chatham-Kent as part of their permitting processes, if necessary.
The construction crew is typically anticipated to require approximately six people and the timeline for constructing
an access road to a turbine is expected to take between two and four days to complete, depending on the length of
the road and site conditions. Equipment will typically include, at a minimum, trucks, graders and bulldozers. The
trucks and graders will likely be driven to the site and the bulldozers will be transported via trailers. The chemicals
likely required for this phase will include oils, gasoline and grease used to operate construction equipment. Fuel-
handling will be conducted in compliance with the mitigation measures outlined in Section 8 below.
5.3.3 Construction of Laydown Areas
Approximately 10 to 20 acres of land area may be constructed for the temporary storage of construction material/
equipment/ components and as a site(s) for the construction office trailers, staff vehicle parking and other
construction related needs. Following clearing and grubbing of any vegetation, the topsoil at the temporary laydown
area will be removed and a layer of clean compacted crushed gravel will be imported, as needed. A temporary
electrical service line may be connected to the existing distribution line for the purpose of providing power to the
construction office trailers.
Equipment will include, at a minimum, trucks, graders and bulldozers. The chemicals required for this phase will
include oils, gasoline and grease used to operate construction equipment. Fuel-handling will be conducted in
compliance with the mitigation measures outlined in Section 8 below.
Following the construction phase, the gravel will be removed from the Laydown areas or re-used, at the discretion
of landowners. The temporary electrical service line and poles will be removed. The stockpiled topsoil will then be
redistributed throughout the temporary laydown area.
5.3.4 Construction of Turbine Working Areas
Temporary working areas will be constructed at the same time as the access roads and will be located adjacent to
the turbine locations. Bulldozers will remove topsoil and subsoil, and working areas locations will be either left as
subsoil or filled with a varying mixture of granular base material and crushed gravel depending on site specific
conditions. Crane mats will be used to stabilize cranes during their operation. The total working area at each turbine
will be approximately 2.5 acres.
The construction crew is typically anticipated to require approximately six people and construction activities are
expected to last for approximately two to four days. Equipment will include, at a minimum, trucks, graders and
bulldozers. The chemicals required for this phase will include oils, gasoline and grease used to operate construction
equipment. Fuel-handling will be conducted in compliance with the mitigation measures outlined in Section 8 below.

5.3.5 Delivery of Equipment
Equipment will be delivered by truck and trailer throughout the construction phase and stored at the temporary
laydown areas surrounding each turbine. Each turbine site will include required infrastructure to accommodate
delivery of oversized loads (e.g., turbine components). A Road Use Agreement and Traffic Management Plan will
be developed in consultation with the Municipality of Chatham-Kent, if required. Alternative traffic routes will be
prepared to address traffic congestion, as needed.
5.3.6 Construction of Wind Turbine Foundations
A determination of a final turbine foundation design will be based on results of site-specific geotechnical
assessments. Based on site specific conditions that will be determined from geotechnical assessment, blasting will
likely not be required during wind turbine foundation excavation. If required, a batch plant will likely be located at
the temporary construction laydown area for the purposes of providing concrete for the turbine foundations.
5.3.6.1 Spread Footing Foundation
For typical spread footing foundations, the expected dimensions of the wind turbine foundation excavation are
approximately 0.25 acres with an excavated depth of approximately 5 m. Stockpiled material will have topsoil and
subsoil separated out and surplus excavated material may be removed from the site for disposal in an approved
manner. The foundation will be constructed of poured concrete and reinforced with steel.
Typical construction equipment, on a per turbine basis, will include excavator for removing material, flatbed trucks
for delivery of rebar, turbine mounting assembly and forms, truck mounted crane or rough terrain forklift for
unloading and placement of rebar and forms, concrete trucks for delivery of concrete (up to 125 trucks),
construction trucks (three to four vehicles with multiple visits); and, dozer, loader and trucks to backfill and compact
foundation and remove surplus excavated materials. Chemicals required for this phase will include oils, gasoline
and grease used to operate construction equipment, as well as concrete curing compounds, and oils for formworks.
Fuel-handling will be conducted in compliance with the mitigation measures outlined in Section 8 below.
5.3.6.2 Deep Foundations
Where required due to soil conditions, deep foundations will be used in place of spread footing foundations. In this
case, steel, concrete or aggregate piles will be installed in the ground to support the forces from the turbine. After
the piles are installed to a suitable depth, a pile cap will be installed and a mud slab will be poured to allow for the
installation and construction of the structural re-bar cage. Concrete will be poured within and around the re-bar
cage to form the foundation. The construction timeframe for turbine foundation is approximately fourteen to twenty
days, excluding curing time.
Typical construction equipment, on a per turbine basis, will include excavator for removing material, flatbed trucks
for delivery of rebar, turbine mounting assembly and forms, truck mounted crane or rough terrain forklift for
unloading and placement of rebar and forms, concrete trucks for delivery of concrete (up to 125 loads), construction
trucks (three to four vehicles with multiple visits); and, dozer, loader and trucks to backfill and compact foundation
and remove surplus excavated materials as well as pile driver or pile boring machinery. Chemicals required for this
phase will include oils, gasoline and grease used to operate construction equipment, as well as concrete curing
compounds, and oils for formworks. Fuel-handling will be conducted in compliance with the mitigation measures
outlined in Section 8 below.

5.3.7 Wind Turbine Assembly and Installation
Turbine components will arrive on-site using trailers and will be temporarily stored on-site in the immediate vicinity
of the base prior to assembly, or possibly in a laydown area. Wind turbines will be assembled on-site by qualified
installers. Typically two cranes will be used to install the turbines. Cranes and crew will erect the wind turbines once
the foundations are completed and the concrete has sufficiently cured. Upon completion, packing frames for the
turbine components may be returned to the turbine vendor.
Equipment will include, at a minimum, trucks and two cranes. The trucks will be driven to the site. The larger track
mounted crane can move from turbine site to turbine site; however, it may need to be disassembled to move it
along roadways and from the Project site. Alternatively, cranes may be moved between turbine sites without
disassembly along access roads. In such instances, no additional infrastructure is required to support the crane
movement. The chemicals required for this phase will include oils, gasoline and grease used to operate
construction equipment. Fuel-handling will be conducted in compliance with the mitigation measures outlined in
Section 8 below.
5.3.8 Construction of the Electrical Collector System
The electrical collector system will consist of, junction boxes and underground or above ground cabling installed
along turbine access roads on private property and either buried or above ground collector lines running along
municipal road RoW. These components are described below.
5.3.8.1 Collector Transformers
No external collector transformers will be constructed; collector transformers will be located within the wind turbines.
5.3.8.2 Collector Lines
Cables will carry electricity from each turbine to the electrical substation. Similarly, fibre optics lines will be installed
to allow for communications between the turbines and the substation. The collector lines may be a combination of
underground, overhead lines on private property, or overhead or underground lines on public road allowances.
All underground collector lines will be installed in a trench or direct plow and buried in accordance with ESA
standards. This depth will likely be deeper than 0.75 m below ground surface. Collector lines may also be installed
in conduits by directional drilling. Where two or more underground collector lines must be connected together, a
junction box will be installed either below or aboveground. Junction boxes may contain equipment related to
splices, junctions, cable splices, surge/lightning arrester, and disconnect switches. They can be located on private
lands or within the RoW.
Overhead collector lines, if required, will be installed using wood, steel or concrete pole structures. The depth and
spacing of these poles will be confirmed during the detail design phase of the Project. To minimize potential impact,
the project is contemplating a joint pole usage agreement with Hydro One Networks Inc. in order to minimize the
installation of new poles within the RoW.
Equipment required for underground collector line installation will likely include excavators, dozers, dump trucks,
directional drilling equipment, plow machines and compaction equipment. Equipment required for overhead
collector line installation will likely include utility bucket trucks, auguring trucks (or excavators), pole trailers, reel
stand vehicles, an excavator, conductor puller vehicles and tensioner vehicles. Fuel-handling will be conducted in
compliance with the mitigation measures outlined in Section 8 below.

B1_04_Eis (26.10.2016) 14
5.3.8.3 Horizontal Directional Drilling
Electrical cables may need to be installed using horizontal directional drilling to minimize effects on woodlots,
watercourses, or private property. Erosion control devices will be installed at the drill location and drill cuttings will
be collected and removed from the site for disposal in an approved and appropriate manner. An entrance and exit
pit will be excavated on either side of the area to be bored under. The directional drilling equipment will be set up at
the entrance pit and a drill bit attached to rod segments will be advanced until it reaches the exit pit. A slurry of
bentonite and/or polymer mixed with water, or other suitable materials will be injected into the hole while drilling to
help stabilize the bore hole and reduce friction. Once the drill bit has reached the exit pit the drill bit will be removed
and a “reamer” attached and pulled back through the hole to enlarge the bore. The electrical cable will then be
installed through the hole and placed in a PVC pipe or sleeve.
If required, equipment used during directional drilling will include a drilling rig and two to three support trucks to
carry drilling rods, drilling supplies and cable. The chemicals required for the drilling will include oils, gasoline and
grease used to operate construction equipment, and the polymer used for directional drilling. Fuel-handling will be
conducted in compliance with the mitigation measures outlined in Section 8 below.
5.3.9 Construction of the Electrical Substation and Interconnection Station
The electrical substation, including the interconnection station will be constructed on a total area of approximately
10 acres within a larger construction disturbance area that may include the operations and maintenance building,
interconnection station as well as a communications tower that is up to approximately 100 m in height. Topsoil and
subsoil will be removed (and stockpiled for restoration) to create an even work surface and the electrical substation
will be constructed on a raised pad or a prepared base on engineered fill.
The transformer area foundation may be approximately 50 m2 and may have a depth of approximately 2 m. An
imbiber bead containment system, an oil-water separator containment system, or another type of system may be
installed. If an oil-water containment system is used it would likely be connected to the drainage system through an
oil water separator that will likely be buried below grade. Any spills will be handled in accordance with the
MOECC’s Spills and Discharges Reporting Protocol as required under Sections 15 and 92 of the Ontario
Environmental Protection Act.
The POI will require modifications to the existing transmission line and may include circuit breakers, isolation
witches, transmission switchgear, instrumentation, grounding, metering equipment and other equipment typical of
such systems. The interconnection plan for any wind project is subject to study, design and engineering by the
IESO which manages the province’s electricity grid and Hydro One which owns the transmission lines.
Equipment required for the construction and installation of the electrical substation will include flatbed trucks,
tracked bulldozers, dump trucks, excavators, compaction equipment, concrete trucks, concrete pump trucks, water
trucks and a crane. Fuel-handling will be conducted in compliance with the mitigation measures outlined in Section
8 below.
5.3.10 Construction of the Operations and Maintenance Building
If required, the operations and maintenance building will likely be a structure constructed on a concrete foundation
with a potential footprint of approximately 0.5 acres, in addition to a parking area. This building may accommodate
offices, maintenance work areas, and control facilities. An access road to the building will be constructed to
accommodate construction equipment and on-site traffic during the operation of the proposed project.
Otter Creek Wind Farm LP
Otter Creek Wind Farm
Environmental Impact Study
B1_04_Eis (26.10.2016) 15
Equipment will include, at a minimum, forklifts, concrete trucks and smaller crew trucks. The chemicals required for
this phase will include oils, gasoline and grease used to operate construction equipment. Fuel-handling will be
conducted in compliance with the mitigation measures outlined in Section 8 below.
5.3.11 Construction of Permanent Meteorological Towers
One or more permanent meteorological towers may be constructed using cranes, and other equipment, and
secured with guy wires tied off to anchors. The towers will be connected to the Project power and communication
infrastructure and there is a possibility the meteorological towers will host communications equipment, serving the
purpose of the communication tower. Construction of one meteorological tower will take approximately two days
and typically may require a crew of approximately six people.
5.3.12 Construction of Communication Tower
A Communication tower used for communication purposes may be constructed within the substation construction
disturbance area. If required, the Communication tower may be up to 100 m tall and will likely be installed by a
single crane; soil conditions will determine whether the tower will be steel-lattice or guyed. An access road may be
constructed to access the Communication tower and the site may be surrounded by a chain link fence.
5.3.13 Site Clean-up and Reclamation
Site clean-up will occur throughout the construction phase meaning waste and debris generated during the
construction activities will be collected by a licensed operator and disposed of at an approved facility and all
reasonable efforts will be made to minimize waste generated during construction. The waste that is generated
during construction will be recycled where possible, including returning packaging material to suppliers for re-use.
Once construction is completed construction equipment and vehicles will be removed from site and site reclamation
will occur. Temporary disturbance areas (e.g., laydown areas and turbine working areas) will be restored by
replacing and re-contouring stripped soil to return the land to previous conditions, at the discretion of the
landowner. Erosion control equipment will be removed once inspections have determined that the threat of erosion
has diminished to the original land use level or lower. Access road widths and entrances that are required for
operation phase will also be reduced to from approximately 20 m to a range of 5 to 12 m in width. High voltage
warning signs will be installed at the electrical substation and elsewhere, as appropriate.
Turbine Commissioning 5.4
Testing and commissioning will be performed prior to the Project’s connection to the existing Hydro One
transmission line. The commissioning activities will consist of testing and inspection of electrical, mechanical and
communications systems for system continuity, reliability and performance. Some packing-material waste may be
generated. Recyclable materials will be separated from non-recyclable materials and both streams will be removed
from the site and disposed of at an approved and licenced facility.
Temporary portable generator sets may be used to electrically commission the turbines prior to connection to the
grid. Following the commissioning phase, the portable generators will be removed from the site.
Equipment will include support trucks which will be driven to the construction site. The only chemicals required for
this phase are oils, gasoline, lubricants and grease used to operate construction equipment and portable
generators.. Fuel-handling will be conducted in compliance with the mitigation measures outlined in Section 8
below.

B1_04_Eis (26.10.2016) 16
Temporary Uses of Land 5.5
Construction and installation activities will utilize temporary turbine work areas and laydown areas adjacent to
access roads, wind turbines, the collector substation, the operations and maintenance building (if required), and
possibly other areas as deemed necessary. Lands used for temporary turbine work areas and laydown areas will
be converted from their current state prior to construction. Soil management will be incorporated into the creation
and use of these areas to facilitate site reclamation, and all temporary work spaces will be converted back to their
previous land use after the completion of the construction and installation phase. Temporarily-used areas will be
reclaimed no later than two years from initial construction disturbance.
Temporary Water Takings 5.6
During construction of the wind turbine foundations, dewatering will be required and is expected to exceed
50,000 L/day. During the construction phase of the Project, water may be required to support turbine infrastructure
construction and water demands for the purposes of these general construction activities are expected to have peak
volumes up to 40,000 Litres/day (L/day). Actual daily demands will vary and will typically be lower in volume than the
estimated peak volume. The following construction activities are examples of some of the activities that may require
water taking during construction:
Dust suppression;
Directional drilling; and
Site clean-up and reclamation.
Any water taking conducted throughout the Project (including construction phase) is subject to the REA application
and as such does not require a separate Permit to Take Water (PTTW).
A desktop hydrogeological assessment was completed for the purpose of providing a high level review of existing
hydrogeological conditions within the Project Boundary. The assessment identified potential groundwater taking
needs of the Project during construction and operation, outlined potential effects of the Project on groundwater
resources, and provided a mitigation strategy and contingency measures to negate any adverse effects. Please
refer to the Otter Creek Wind Farm Hydrogeological Assessment and Effects Assessment (AECOM, 2016e) for
further information.
Construction Materials / Waste Generation and Transportation 5.7
Materials brought to the Project during construction and installation will include equipment / component packaging,
scraps, fuels and lubricants. Packing frames for the wind turbine components and cabling spools will be returned to
their respective vendors or may be recycled. Plastics from other containers and packaging will be disposed of
through the local landfill and recycling facilities, where appropriate. Construction materials and scrap metals (e.g.,
copper wiring and conductors) will be removed and most likely sold to a local scrap metal dealer. Oils, fuel and
lubricants used in maintenance and operation of construction equipment will be stored temporarily in accepted
containment systems and will subsequently be removed by a licensed contractor. The licensed contractor will be
required to dispose of these wastes through conventional oil and hazardous waste disposal streams.
In addition, concrete wash out of empty cement trucks will adhere to applicable regulations. Sanitary sewage collected
in portable toilets and wash stations will be transported to an off-site facility by a licensed hauler. Small amounts of
refuse material from borehole drilling during geotechnical surveys may be redistributed on disturbed areas at
respective drill sites. Topsoil and/or subsoil stripped from access roads, foundations and temporary turbine work areas
/ laydown areas may be re-used on-site, where feasible, or otherwise removed to an appropriate location.

Environmental Impact Study
B1_04_Eis (26.10.2016) 17
If any grubbing of the site is required prior to construction activities, the grubbing materials (e.g., vegetation,
branches and tree stumps) will likely be removed but may remain on-site and/or possibly buried within disturbance
areas. During construction of the wind turbine foundation, electrical substation and other infrastructure, excavated
subsoil and topsoil will likely be stored in piles on-site at each temporary storage / laydown area until they are
replaced during clean-up and reclamation activities. As required, stockpiles may be covered following best
management practices (“BMPs”) to prevent erosion and propagation of noxious weeds. Any excess subsoil will be
distributed with landowner input or taken off-site, and excess clean topsoil will be redistributed to adjacent lands as
appropriate. If contaminated soil is encountered during the course of excavations, this soil will be disposed of in
accordance with the current appropriate provincial legislation.
Disposal and recycling of materials and waste generated will likely require the use of flatbed and large dump trucks
that are capable of transporting heavy loads. The type and number of truck trips necessary will be determined by
the licensed construction contractor prior to the construction and installation of the Project. Disposal and recycling
of waste will occur throughout the construction and installation of the Project since there are no plans for long-term
storage of waste in the Project Location.

6. Overview of Potential Environmental Effects
The preferred method for the management of potential environmental effects is through the avoidance of significant
natural features during the Project planning and layout design process. Alternatives for conducting the proposed
activity were considered during the planning stages of the Otter Creek Wind Farm in order to avoid adverse effects
to significant natural features to the extent possible, while working within other constraints including noise, lease
agreements and landowner preference. Alterations to the proposed layout occurred throughout Project
development as significant natural features were identified, including relocation of Project infrastructure away from
sites that support sensitive species and their habitats, spanning significant natural features and/or implementing
directional drilling techniques to avoid above-ground disturbance to significant natural features. Mitigation
measures and monitoring commitments to address potential effects that may occur where complete avoidance was
not possible are described in this EIS.
Construction activities within 120 m of significant natural features may result in accidental intrusion causing physical
damage to vegetation, increased erosion and sedimentation, disturbance to local wildlife through mortality, risk of
soil or water contamination, and changes in natural drainage patterns. These potential effects are anticipated to be
avoided or minimized through the application of the mitigation measures described herein.
A general discussion of additional potential effects specific to different types of Project infrastructure is provided below.
Potential Effects of Wind Turbines 6.1
The Natural Heritage Assessment process focuses on the consideration and protection of Significant Wildlife
Habitats during the Project planning and layout design process. This habitat-based approach is a key factor in
preventing negative effects on birds and bats (MNRF, 2011a, 2011b). Alterations to the proposed Otter Creek Wind
Farm were made during the planning and layout design stages of this Project to avoid Significant Woodlands and
Significant Wildlife Habitat to the extent possible, while working within other constraints. All of the Otter Creek Wind
Farm turbines will be located within agricultural fields; therefore, no direct loss or fragmentation of significant natural
features will occur as a result of turbine installations. Furthermore, no turbines will be located within 120 m of a
significant bird or bat habitat feature. Mitigation measure to address potential effects of site preparation, grading
and construction activities where turbines will be installed adjacent to significant natural features are described in
Sections 7 and 8 below.
In North America, wind turbines present less of a danger to birds than other anthropogenic sources of mortality
such as buildings or roads (Erickson, et al. 2001). However, birds and bats may be injured or killed through
collisions with moving turbine blades, and air pressure changes near moving turbine blades may also result in bat
mortality. On the basis of bird mortality monitoring results from Ontario wind power projects, the MNRF has
concluded that mortality resulting from wind turbines is not considered to be a concern for most of Ontario’s bird
populations (MNRF, 2011a). Potential effects of the proposed Project on bird and bat mortality are addressed in the
Otter Creek Wind Farm Environmental Effects Monitoring Plan (AECOM, 2016c).
Some temporary construction dewatering may be required during construction at specific turbine locations.
Construction dewatering may temporarily affect water levels in significant features that are present within the
dewatering zone of influence. As described in the Otter Creek Wind Farm Hydrogeological Assessment and Effects
Assessment (AECOM, 2016e), the anticipated dewatering zone of influence (ZOI) was estimated to be 165 m
measured from the limits of a typical turbine foundation. There are no significant natural features located within the
anticipated ZOI.

B1_04_Eis (26.10.2016) 19
Potential Effects of Access Roads 6.2
All of the Otter Creek Wind Farm access roads will be constructed within the Construction Disturbance Area and
therefore are outside of significant natural features; therefore, no direct loss of significant natural features will occur
as a result of access roads. During Project operation, access roads may result in wildlife mortality through collision
with vehicular traffic; however this potential effect is anticipated to be negligible given the agricultural nature of the
area and limited volume of maintenance vehicles. Mitigation measures to address potential effects of site
preparation, grading and construction activities where access roads will be installed adjacent to significant natural
features are described in Sections 7 and 8 below.
Potential Effects of Collector Lines 6.3
All of the Otter Creek Wind Farm collector lines will be constructed outside of significant natural features on
privately owned lands or in municipal road Right-of-Ways (RoW) within the Construction Disturbance Area.
Locating crossings of significant natural features within existing road RoW is often the preferred alternative for
avoiding or limiting negative effects to these features, given that these locations are typically already disturbed by
the existing road and subject to routine maintenance associated with the road. Mitigation measures to address
potential effects associated with site preparation, grading and construction activities where collector lines will be
installed adjacent to significant natural features are described in Sections 7 and 8 below.
Potential Effects of Other Project Infrastructure 6.4
While exact locations of other Project infrastructure (e.g., electrical substation, communications tower,
meteorological towers, interconnection station, operations and maintenance building), have not yet been confirmed,
this infrastructure will be located outside of significant natural features and wholly located within the Construction
Disturbance Area. Therefore, there will be no direct loss of significant natural features as a result of other Project
infrastructure. Mitigation measures to address potential effects of site preparation, grading and construction
activities where other Project infrastructure will be installed adjacent to significant natural features are described in
Sections 7 and 8 below.

7. Significant Woodlands
This section describes potential environmental effects of the proposed Project on Significant Woodlands during the
construction, operational and decommissioning phases. The Otter Creek Wind Farm will be constructed outside of
Significant Woodlands on privately owned lands or in municipal road Right-of-Ways (RoW) within the Construction
Disturbance Area (CDA). All potential effects associated with construction and operation of collector lines outside
Significant Woodlands will be avoided or minimized through the application of mitigation measures, monitoring
methods and contingency measures as described herein.
Mitigation measures to address potential negative environmental effects of Project construction, operation and
decommissioning on Significant Woodlands are presented in Table 7-1. This table describes the potential effects,
performance objective, mitigation measures, residual effects expected to remain after mitigation measures are
applied and the significance of these residual effects. Table 7-1 also describes the proposed monitoring plan and
contingency measures, as they relate to Significant Woodlands located within the Area of Investigation (refer to
Figure 2 in AECOM, 2016d for locations).

Utilize erosion blankets, sediment control fencing, straw bales, siltation bags, silt socks (i.e., Flitrexx
Soxx), etc. for construction activities within 30 m of a Significant Woodland, as appropriate to mitigate
potential excessive erosion and sedimentation.
Extra erosion and sediment control materials will be kept on hand, (i.e., heavy duty silt fencing, straw
bales).
Schedule clearing and grubbing, excavation and/or backfilling within 30 m of Significant Woodlands to
avoid times of high runoff volumes wherever possible. Temporarily suspend work if high runoff volume
is noted or excessive flows of sediment discharges occur until mitigation measures are in place.
Store any stockpiled materials at least 30 m away from Significant Woodlands.

Regularly during active construction periods;
Prior to, during and post forecasted large rainfall events (>20 millimetres in 24
hours) or significant snowmelt events (i.e., spring freshet);
Daily during extended rain or snowmelt periods;
Monthly during inactive construction periods, where the site is left alone for 30

8. Significant Wildlife Habitat
This section describes potential environmental effects of the proposed Project on Significant Wildlife Habitat (SWH)
during the construction, operational and decommissioning phases. All potential effects to SWH will be avoided or
minimized through the application of mitigation measures, monitoring methods and contingency measures as
described herein.
The following SWH features were carried forward for consideration in this EIS:
Habitat for Plant Species of Conservation Concern (SOCC) features SCP-005, SCP-006 and SCP-007.
The Otter Creek Wind Farm will be constructed outside of SWH features on privately owned lands or in municipal
road Right-of-Ways (RoW) within the Construction Disturbance Area (CDA). Although features SCP-006 and SCP-
007 are located within 120 m of the Project Location / Construction Disturbance Area which may contain access
roads, these features are on the opposite side of Langstaff Road; therefore, operational effects related to Project
access roads are not anticipated. Additionally, where small portions of these cultural vegetation communities
extend into the road RoW they are considered disturbed by the operation and maintenance of the existing road;
therefore construction and maintenance of collector lines within the CDA is not anticipated to negatively affect these
features. The access road to turbine 1 may be located within 0 m of feature SCP-005 however the subject portion
of feature SCP-005 is also located along Langstaff Road and is already disturbed by the operation and
maintenance of the existing road. All potential effects of the proposed Project on SWH features will be avoided or
minimized during the construction, operation and decommissioning phases, provided mitigation measures
described in Tables 8-1 and 8-2 are applied.
In addition to the above SWH features, the following Generalized Candidate SWH features were carried forward for
consideration in this EIS:
Bat Maternity Colonies (Natural Areas 012 and 016);
Turtle Wintering Areas (Natural Areas 005 and 017);
Amphibian Breeding Habitat (Wetland) (Natural Area 005);
Habitat for Plant Species of Conservation Concern (Natural Areas 012 and 016); and,
Habitat for Reptile Species of Conservation Concern (Natural Areas 005 and 017).
Mitigation measures to address potential effects on generalized candidate SWH are described in Table 8-1. These
mitigation measures will also be applied to all SWH features as described above. Additional mitigation measures to
address potential environmental effects of Project construction, operation and decommissioning on specific SWH
features are presented in Table 8-2. These tables describe the potential effects, mitigation measures, residual
effects expected to remain after mitigation measures are applied and the significance of these residual effects, as
well as the proposed monitoring plan and contingency measures.

Accidental intrusion into
generalized candidate SWH
resulting in damage to trees.
Avoid accidental
intrusion into SWH.
For collector lines located within Public RoW, vegetation removal (if any) will be kept to a minimum and will be
limited to the road RoW. Trees within the RoW will be pruned through implementation of proper arboricultural
techniques, under supervision of an Arborist or Forester.
Where construction occurs within 30 m of SWH, install and maintain protective fencing to clearly define the
construction area and prevent accidental damage to vegetation.
Where excavation for construction of collector lines is conducted within the rooting zone of trees (e.g., within 5
m of the dripline), implement proper root pruning measures to protect tree roots.
Accidental intrusion will be avoided through
clear delineation of boundaries and
protective fencing as well as root pruning
measures.
Negligible residual effects.
Undertake site inspections by an Environmental Monitor during construction events to
ensure that only specified trees are removed, protective fencing is intact and that there
is no damage caused to remaining trees during construction.
Contingency Measures:
Repair protective fencing if damaged.

functioning prior to conducting daily work and re-install or repair as required prior to
commencing daily construction activities.
Monitor on-site conditions (i.e., erosion and sediment control, spills, flooding, etc.)
where construction occurs within 30 m of a feature on the following basis:
Regularly during active construction periods;
Prior to, during and post forecasted large rainfall events (>20 millimetres in 24 hours)
or significant snowmelt events (i.e., spring freshet);
Daily during extended rain or snowmelt periods;
Monthly during inactive construction periods, where the site is left alone for 30 days or

Notify the MOECC Spills Action Centre of the “frac-out” event and the response taken to contain the spill.
Monitor clean-up procedures to ensure they do not result in greater damage than leaving the mud in-place.
If the spill affects a SWH feature, seed or replant the area using the same species to those in the adjacent
area, or allow to re-grow from existing vegetation.
Increased erosion and sedimentation
avoided or minimized through application of
mitigation measures.
Low likelihood; if accidental damage
occurred, negative effects may be
measurable but would likely represent a
small change relative to existing conditions.
See erosion and sedimentation above.
Monitor directional drilling for the duration of such activities by an Environmental Monitor
to ensure that “frac-out” or accidental intrusion does not occur, and if it does, to ensure
that there are no effects on SWH features.
Contingency Measures:
In the event of a “frac-out”, implement the “Frac-Out” Contingency Plan.
Soil or water contamination by
release of pressurized drilling
fluids into SWH from fractures
in substrate (also known as a
‘frac-out’).

9. Potential Direct Effects of Wind Turbine Operation on Birds and Bats
Potential effects of the proposed Project on bird and bat mortality are addressed in the Otter Creek Wind Farm
Environmental Effects Monitoring Plan (AECOM, 2016c; hereafter referred to as the EEMP). The EEMP outlines
rigorous monitoring requirements to address potential impacts on bird and bat species during operation. More
specifically, the EEMP summarizes potential effects; identifies performance objectives with respect to the potential
negative effects; describes mitigation measures to achieve the performance objectives; identifies contingency
mitigation measures to be implemented based on the monitoring results; and commits to future monitoring to
ensure the mitigation measures meet the performance objectives (refer to Table 9-1 below). The results of all post-
construction monitoring conducted according to the EEMP will be submitted to the MNRF for review on an annual
basis.

10. Summary and Conclusions
The landscape surrounding the Project Location and generally within the Project Boundary is characterized by
intensive agricultural production. A limited number of natural features are present and are largely in the form of
hedgerows, isolated woodlands and riparian vegetation limited to the edges of watercourses within the Project
Boundary.
As a result of the local landscape and the efforts of Otter Creek Wind Farm Limited Partnership in relocating the
Project Location away from significant natural features, it has been possible to derive a layout of turbines and
associated infrastructure that largely avoids significant natural features. The Otter Creek Wind Farm will be
constructed outside of significant natural features on privately owned lands or in municipal road Right-of-Ways
(RoW) within the Construction Disturbance Area. Locating crossings of significant natural features within existing
road RoW is the preferred alternative for avoiding or limiting negative effects to these features, given that these
locations are already disturbed by the existing road and subject to routine maintenance associated with the road.
Vegetation communities present within the road RoW are considered disturbed by the operation and maintenance
of the existing road; therefore no negative effects are anticipated from construction and maintenance of collector
lines within the full limits of the road RoW.
The potential operational effects of turbines on birds and bats will be monitored for the first three years post-
construction and, if required, mitigation measures will be implemented in consultation with MNRF and in
accordance with provincial guidelines and requirements. As a result, the residual effects of the Project on significant
natural features are expected to be minimal, provided the mitigation measures described herein are applied
correctly based on site-specific conditions, and proactively managed throughout the duration of construction and
operation activities.
