1. Introduction

1.1 Name of Applicant

In May, 2009, the Government of Ontario passed the Green Energy and Green Economy Act and Ontario

Regulation (O. Reg.) 359/09, as amended. Under the amended O. Reg. 359/09, the Otter Creek Wind Farm Project

(the Project) will require a Renewable Energy Approval (REA). The REA integrates previous requirements under

the Environmental Assessment Act with provincial rules and standards under the Environmental Protection Act.

The Project is being proposed by Otter Creek Wind Farm Limited Partnership (Otter Creek), a partnership of

Renewable Energy Systems Canada (RES Canada), Boralex Inc., and Walpole Island First Nation. 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 after commercial operation commences.

This 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 Project Description Report (PDR) has been prepared in accordance with

Item 10 of Table 1 in O. Reg. 359/09, as amended.

This PDR, along with the rest of the draft REA reports was provided to Municipality of Chatham-Kent 90 days in

advance of the second public meeting. It was also provided to First Nations and Aboriginal communities,

government agencies and the public for review 60 days in advance of the second public meeting. These timelines

align with the requirements outlined in O. Reg. 359/09, as amended.




1.2 Project Location

Under 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

consists of the construction disturbance area (CDA) and the blade swept area of the turbines. The CDA identifies

the location of permanent and temporary Project components.

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 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. Figure 1-1 shows a map

of the Project Location.

The Project Location encompasses approximately 820 acres 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

area surrounding the Project also consists of fragmented areas of forest and riparian habitat associated with the

Sydenham River, which bisects the Project in a north-south direction, as well as other small creeks and/or farm

drains. The following co-ordinates define the general limits of Project Location:

2. Project Components and Ancillary Facilities

A description and listing of Project components and temporary Project components are outlined below in Table 2-1

and Table 2-2, respectively.

Table 2-1: Description of Project Components

Component Description

Wind Turbine

Generators

The Project will include wind turbines with a project total nominal power up to 50 MW. 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 CDA 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 CDA on private property and

within the public RoW until it reaches the Electrical Substation.

The underground collector lines will be buried in accordance with Electrical Safety Authority standards. This depth will

likely be deeper than 0.75 m below ground surface. If above ground electrical collector lines are required, they will be

constructed on wood, steel or concrete pole structures.

Where two or more underground collector lines must be connected together, a junction box may be installed either below

or above ground. 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.

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 System Operator

(IESO) market rules), substation grounding, parking, emergency generator, service transformer 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 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.

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 HONI 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 Location.

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.




To facilitate the construction of the proposed Project, a number of temporary construction components are required.

These temporary components, described further in Table 2-2 below, include turbine working areas and construction

laydown area(s).

Table 2-2: Description of Temporary Project Components

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.




3. Project Activities

substation equipment, permitting and detailed design. Otter Creek will continue to communicate and engage

landowners, First Nations and Aboriginal communities, and the Municipality of Chatham-Kent, as required, during

this phase of the Project.

The REA process is the primary approval requirement in the pre-construction phase of the Project. For the permits

and authorizations listed in Section 1.6, Otter Creek will work directly with the respective federal, provincial and

municipal authorities to ensure all applicable requirements are met.

3.3 Construction

Construction of the Project is scheduled to begin in spring 2018 and is planned to be completed by late 2018 or

2019. During site preparation and construction of the proposed Project, the following key activities may be

undertaken:

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.

3.4 Operations and Maintenance

Operation of the Project is expected to begin in late 2018 or 2019. The operational lifespan of the Project is

approximately 20 years, but may be extended. The operation of the proposed Project may require up to four trained

technical and administrative staff, including turbine maintenance technicians and a site supervisor.

During this phase, the following key activities will be undertaken:

Preventative and unplanned maintenance of Project components;

Otter Creek staff transport;

Meter calibrations;

Remote operation of the wind turbines; and

Grounds maintenance in the vicinity of Project components.

On-site activities will be limited primarily to scheduled maintenance of the Project components.

3.5 Decommissioning

During the decommissioning phase of the Project wind turbine structures will be removed to the base of the

foundation and portions of the foundations will be excavated and backfilled with subsoil and topsoil to allow

agricultural activities to continue. Access road removal will be dependent on the requirements and agreements in

place with the individual landowner. Impacted lands will be restored to pre-construction state at the discretion of

landowners. Decommissioning procedures will be similar, but in reverse order to those carried out in the

construction phase.

Key decommissioning activities associated with the proposed Project include:

Disassembly and removal of wind turbine infrastructure (hubs, nacelles, blades and towers, collector

transformer);

Reclamation of agricultural land (at the discretion of landowners);

Removal of all electrical collectors above ground infrastructure (at the discretion of landowners). Where

the underground collector lines come to the surface, the collector lines will be cut and excavated to a

minimum depth of 0.75 m below grade;

Turbine foundations will be removed to a depth of approximately 1 m;

Disconnection of the electrical substation and removal of the connection line;

Disassembly and removal of the electrical substation, communication and meteorological towers, if

required, and transmission and grid connection infrastructure (foundations will be removed to a depth

of approximately 1 m); and

Disassembly and removal of the operations and maintenance building infrastructure (at the discretion

of the landowners and if required).




3.6 Construction Materials, Waste Generation and Transportation

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 may be 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 spoil 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

storage / laydown areas may be re-used on-site, where feasible, or otherwise removed to an appropriate location.

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 CDA. 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 will 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 CDA.

3.7 Toxic / Hazardous Materials

Machinery used to dismantle and remove Project components will require the use of oils, fuels and lubricants. In

addition, waste lubricants will be recovered during the dismantling of Project components, including the electrical

substation, wind turbine generators and operations and maintenance building (if required). 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. These materials will be disposed of through conventional waste-oil

and hazardous waste disposal streams in a manner outlined by regulatory agencies, if required, at the time of

decommissioning.

Overhead collector lines, if required, for the Project may be constructed on a wooden, steel or concrete monopole

structure. If wooden monopole structures are used, these poles typically use a chemical-treated exterior. Otter

Creek will discuss the recycling of wooden poles with a licensed facility, which would likely involve stripping the

chemically-treated exterior, disposing of this chemically-infused wood in a landfill, and re-milling the remaining

wood core for alternative end uses.




3.8 Air Emissions

During each phase of the Project, activities requiring the use of motorized vehicles (e.g., transportation of

maintenance personnel to turbine sites) will have infrequent, short-term, and low levels of emissions of greenhouse

gases (GHGs) and other compounds. These emissions will be negligible compared to normal operation of

motorized vehicles in and around the Project Location. Section 4.4 of this Report outlines potentially negative

effects to air quality relating to the Project and identifies mitigation measures proposed.

Project noise emissions will adhere to the requirements of O. Reg. 359/09, as amended. Project activities are not

anticipated to generate significant odour emissions as a result of the construction and operation of the Project.

3.9 Sewage

During site preparation and construction, portable toilets will be used and a licensed contractor responsible for

waste removal will be engaged. The operations and maintenance building, if built for the Project, may include

washroom facilities that will be constructed and serviced in accordance with required regulations.

Potable water may be supplied by a well(s) or through the municipal water system and a septic bed will be

constructed for the disposal of sewage. Otter Creek will be responsible to ensure proper maintenance of the septic

system. The operations and maintenance building, septic system and water supply would be constructed and

operated in accordance with all applicable (e.g., municipal and provincial) standards.

3.10 Stormwater Managements / Erosion and Sediment Control

To effectively manage runoff during the operation of the Project, drainage channels may be constructed. The

decision of the need for and location of drainage channels will be made during the detailed design stage of the

proposed project. No additional sedimentation control measures are anticipated to be required during operation

since sedimentation from these roads is predicted to be lower than that from agricultural fields where the roads are

constructed.

A graveled area around each wind turbine foundation will receive any precipitation runoff from wind turbine towers

and allow for infiltration into the ground. Runoff from the tower section of wind turbine generators is expected to be

negligible compared to the existing runoff within the Project Location.

3.11 Water-taking Activities

Water takings for the purposes of providing dry working conditions during turbine foundation construction, collection

line installation, road construction, dust suppression and general maintenance activities may be required during

construction of the Project. Any water taking conducted during the construction phase or the operations phase of

the Project 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 vicinity of the Project Location. 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. The following section provides an overview of the Hydrogeological Assessment and Effects Assessment

Report for the Project. The full report can be found in Appendix C of the Design and Operations Report (available

under separate cover).




3.11.1 Temporary Water Takings during Construction

During construction, dewatering will be required for the construction of the wind turbine foundations. Dewatering for

this activity is expected to exceed 50,000 L/day; however this is dependent on the design of the wind turbine

foundation, surficial material being excavated, the depth to the groundwater and other hydrogeological

characteristics which will all be determined during future geotechnical analysis.

During construction, water may be required to support general construction activities and water demands are

expected to have peak volumes up to 50,000 L/day. Actual daily demands will vary and will typically be lower in

volume than the estimated peak volume. The following general 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).

3.11.2 Long Term Water Takings during Operation

Groundwater takings during the operations phase of the Project may be required to provide a non-potable water

source for regular personnel requirements of full-time employees and general operational maintenance at the

operations and maintenance building, should one be constructed. If a well is required, water takings are expected

to be up to approximately 4,500 L/day and are not expected to exceed 50,000 L/day.




4. Description of Potential Environmental Effects

The following section provides a summary of the potential environmental effects that may result from the

construction, operation and decommissioning of the Project. The following assessment of potential environmental

effects is preliminary and has been completed in accordance with the requirements of O. Reg. 359/09, as

amended. The description of environmental effects addresses the following environmental considerations:

Cultural Heritage (Protected Properties,

Archaeological and Heritage Resources);

Natural Heritage;

Impacts on Surface Water and Groundwater;

Emissions to Air, including Odour and Dust;

Noise;

Local Interests, Land Use and Infrastructure;

Other Resources;

Public Health and Safety; and

Areas Protected under Provincial Plans and

Policies.

Each subsection provides a summary of existing conditions followed by a preliminary assessment of potential

environmental effects, including mitigation measures, as a result of construction, operations and decommissioning

of the Project.

For each potential effect, performance objectives were developed to describe a desired outcome of mitigation.

Next, mitigation measures were proposed to achieve the performance objectives. Net effects, which are those

effects that remain following the application of mitigation measures and monitoring commitments, were then

assessed based on professional judgment as well as previous project experience. Where possible, the significance

of adverse net effects has been described based on the following:

Magnitude .......... the size or degree of the effect compared against baseline conditions; and

Likelihood .......... the probability that the effect will occur.

Finally, where monitoring commitments have been identified, they are intended to verify that the mitigation

measures achieve performance objectives. Should the monitoring during the construction and operation of the

Project reveal that the mitigation measures are not achieving the intended results; the identified contingency

measures will then be implemented.

4.1 Cultural Heritage (Protected Properties, Archaeological and Heritage Resources)

4.1.1 Existing Conditions

Stage 1 and 2 Archaeological Assessments (AECOM, 2016a, AECOM, 2016b and AECOM, 2016c) were conducted to

identify the presence of archaeological resources within the CDA. The Stage 1 Archaeological Assessment consists of

an initial desktop archaeological study within 1 kilometre (km) of the CDA. The study determined there was

archaeological potential for both pre-contact Aboriginal and historic Euro-Canadian sites in the CDA.

The Stage 1 Archaeological Assessment was submitted to the MTCS on August 8, 2016, was filed with MTCS on

August 17, 2016 and AECOM received the acceptance letter from MTCS on September 13, 2016. The Stage 2

Archaeological Assessments was submitted to the MTCS in the fall of 2016 for review and acceptance into the

Ontario Public Register of Archaeological Reports.




The Stage 2 Archaeological Assessments of the CDA were conducted between May and November of 2016

(AECOM, 2016b and AECOM, 2016c). The assessments were conducted in accordance with the 2011 Standards

and Guidelines for Consultant Archaeologists (MTCS, 2011). These assessments involved a combination of the

pedestrian survey and test pit survey methods across portions of the study area that are proposed to be impacted

by the project, including turbine locations, access roads, electrical substations, collector lines, operations and

maintenance buildings, meteorological and Communication towers, and turbine working areas. The Stage 2

Archaeological Assessments evaluated the Project CDA, including privately-owned properties and parts of the

municipal ROW of McCreary Line, Richardson Road, and Forhan Street.

The Stage 2 Archaeological Assessments resulted in the identification of two (2) archaeological locations, the first

was identified as a collection of 20th century refuse with a small inclusion of 19

th century glass. The second location

was identified as an isolated pre-contact First Nation findspot. Neither of these locations meets the criteria for

registering with the MTCS as archaeological sites according to Section 7.12, Standard 1 of the Standards and

Guidelines for Consultant Archaeologists (MTCS, 2011). The remaining land was found to be absent of any

archaeological sites or materials.

A Heritage Impact Assessment (AECOM, 2017b) was also completed to identify heritage resources including

cultural heritage features and cultural heritage landscapes of cultural heritage value or interest. All work was carried

out in accordance with O. Reg. 359/09, as amended and included assessing CDA as well as adjacent lots to the

CDA. The report identified three (3) potential heritage properties within the CDA and six (6) potential heritage

properties adjacent to the CDA. The investigation also identified one (1) potential cultural heritage landscape, the

abandoned CSX railway line which crosses through the CDA.

AECOM concluded that there are no direct or indirect impacts of the proposed undertaking on any cultural heritage

resources as part of construction and therefore no mitigation strategies are recommended.

4.1.2 Potential Effects, Mitigation Measures and Net Effects

Construction and Decommissioning

No areas of archaeological interest were identified during the Stage 2 assessments and no potential effects to 10

potential cultural heritage resources within or adjacent to the CDA are anticipated, therefore, no mitigation

measures or monitoring are proposed during construction or decommissioning phases.

Operation

No areas of archaeological interest were identified during the Stage 2 assessments and no potential effects to 10

potential cultural heritage resources within or adjacent to the CDA are anticipated, therefore, no mitigation

measures or monitoring are proposed during operations.

4.2 Natural Heritage Features

The potential effects, mitigation measures, residual effects and monitoring commitments regarding Significant Natural

Heritage Features were identified and evaluated in the Natural Heritage Assessment (NHA) and Environmental Impact

Study (EIS) Report (AECOM, 2017c). Both reports were prepared based on the Natural Heritage Assessment Guide

for Renewable Energy Projects (MNRF, 2012) and submitted to the MNRF for review and sign-off.

Following the completion of the Records Review and Site Investigation for all natural heritage features located in or

within 120 m (or 50 m from collector lines) of the Project Location, an Evaluation of Significance was conducted to

identify any features that required an EIS.





The NHA Records Review, Site Investigation and Evaluation of Significance and EIS Reports were completed in

2016/2017. All reporting has been completed in accordance with applicable natural heritage guidelines, including:

Natural Heritage Assessment Guide for Renewable Energy Projects, 2nd Edition (Ontario Ministry of Natural

Resources and Forestry (MNRF, 2012), Birds and Bird Habitats: Guidelines for Wind Power Projects (MNRF,

2011a) and Bats and Bat Habitats: Guidelines for Wind Power Projects (MNRF, 2011b).

For the purposes of completing the NHA, 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.

The following section outlines some of the existing conditions in the Project Location.

4.2.1.1 Wetlands and Vegetation Communities

A total of 1.97 ha of wetland was identified as occurring within the Area of Investigation. A single wetland, a shallow

marsh with a total size of 1.97 ha was identified within the Area of Investigation. The wetland is less than 2 ha in

size and therefore does not require evaluation under Ontario Wetland Evaluation System (OWES).

During the Site Investigation it was determined that areas within the Area of Investigation are largely represented

by agricultural crops such as corn, winter wheat or soy. Through Ecological Land Classification (ELC) surveys in

areas of natural vegetation, it was noted that Open Aquatic was the most frequency occurring ELC community, due

to the large number of agricultural drains and two large ponds. Meanwhile, the most frequently occurring terrestrial

community within the Area of Investigation is a complex of Cultural Meadow and Cultural Thicket, each a total of

8.07 ha and 6.92 ha, respectively. Further information on the identified wetlands and vegetation communities within

the Project Location can be found within the Site Investigation and the Evaluation of Significance reports for this

project (both available under separate cover).

4.2.1.2 Birds

Waterfowl Stopover and Staging Areas (Terrestrial and Aquatic) were the only candidate and/or generalized candidate

Significant Wildlife Habitats (SWH) for birds identified within the Area of Investigation during the Site Investigation.

During which time, a total of seven features were identified and delineated. Waterfowl Stopover and Staging Areas

(Terrestrial and Aquatic) Evaluation of Significance (EOS) surveys must be undertaken in the early spring, which was

before the confirmation of the Project Location and as such, all seven features whether determined to be candidate or

generalized candidate SWH underwent EOS surveys. Subsequent surveys were conducted in accordance with the

methods described in the Birds and Bird Habitats Guidelines for Wind Power Projects (MNRF, 2011a). Following

which the results of the surveys were compared to the evaluation of significance criteria as outlined in the Significant

Wildlife Habitat Criteria Schedules for Ecoregion 7E (MNRF, 2015) and none of the features were found to be

significant. Consequently none of the features were carried forward to the EIS.




4.2.1.3 Bats

A total of three potential bat maternity roost habitats were identified and delineated during the Site Investigations

within the Area of Investigation; however, none of these are located within 120 m qualifying infrastructure, (i.e., a

turbine) nor were any located within an area where vegetation removal was proposed to be undertaken.

Consequently, these features were carried forward to the EIS as generalized candidate SWH.


The purpose of the NHA EIS Report is to identify, assess and mitigation negative environmental effects; while the

Environmental Effects Monitoring Plan (EEMP) describes the post-construction monitoring plan for bird and bat

mortality and related mitigation and contingency measures, in accordance with MNRF requirements. The report

findings are summarized below.


Table 4-1 provides mitigation measures and net effects for potential effects related to Generalized Candidate SWH

and Natural Heritage Features.

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 a qualified 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.

Any damaged trees will be pruned through implementation of proper arboricultural

Develop and implement an erosion and sediment control (ESC) plan before commencement of construction as

per Ontario Provincial Standard Specifications (OPSD 219.130).

Utilize erosion blankets, sediment control fencing, straw bales, siltation bags, silt socks (i.e., Flitrexx Soxx), etc.

for construction activities within 30 m of SWH, as appropriate to mitigate potential excessive erosion and

sedimentation.

Extra ESC 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 SWH 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 SWH.

Keep sediment and erosion control measures in place until disturbed areas have been stabilized (i.e., re-

vegetated).

Erosion control equipment will be removed once it is determined that the threat of erosion no longer exists.

Previously vegetated areas (e.g. grassy lawns and roadsides) will be re-vegetated, where required, using an

appropriate seed mix.

Erosion and sedimentation avoided or

minimized through application of mitigation

measures.

Low likelihood and limited magnitude of

Contractor to check that erosion control measures are in good repair and properly

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., ESC, 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 longer.


Suspend work if excessive flows of sediment discharges occur until additional

mitigation measures are in place (e.g., install the extra ESC materials kept on site,

such as heavy duty silt fencing, straw bales, etc.).

Report the details of a flooding event to MOECC, including a description of any

assessment and remediation undertaken.

Monitor SWH for signs of surface disturbance.

Develop “Frac-Out” Contingency Plan outlining steps to contain any chemicals or to avoid contamination of

adjacent SWH including:

Immediately stop all work, including the recycling of drilling mud / lubricant.

Contain any sediments and/or deleterious materials originating from the “frac-out”.

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.

Time vegetation removal to avoid periods of habitat use to the extent possible, particularly to avoid sensitive life

stages (e.g., breeding season for migratory birds, March 31 to August 31). Undertake active nest surveys by a

qualified Biologist in areas defined as simple habitat* if clearing of vegetation must take place during this

period.

*Note: Environment Canada defines simple habitats refer to habitats that contain few likely nesting spots or a

homogenous community where identification of active nests can be completed with confidence. For instance,

sparsely vegetated habitats may be considered simple habitats, depending on site-specific vegetation cover.

Disturbance and/or mortality to terrestrial

wildlife avoided or minimized through

Undertake monthly site inspections by an Environmental Monitor to ensure that only specified

trees are removed, protective fencing is intact and that there is no damage caused to the

remaining trees during construction and undertake active nest surveys by a qualified Biologist

in areas defined as simple habitat* if clearing of vegetation must take place during this period.


Prune any damaged trees through implementation of proper arboricultural techniques,

under supervision of a qualified Arborist or Forester.

If it is determined that additional contingency measures are necessary, further

mitigation measures will be developed and MNRF will be consulted.

Should an active nest be located apply and maintain an appropriate buffer, selected by

a Biologist, based on species specific characteristics until the nest is no longer active.

*Note: Simple habitats refer to habitats that contain few likely nesting spots or a

4.3 Surface Water and Groundwater


4.3.1.1 Surface Water

According to Section 1.1 of the O. Reg. 359/09, as amended, a water body is defined as:

“A lake, permanent stream, intermittent stream and a seepage area but does not include:

a) grassed waterways;

b) temporary channels for surface drainage, such as furrows or shallow channels that can be tilled

and driven through;

c) rock chutes and spillways;

d) roadside ditches that do not contain a permanent or intermittent stream;

e) temporary ponded areas that are normally farmed;

f) dugout ponds; and

g) artificial bodies of water intended for storage, treatment or recirculation of runoff from animal

yards, manure storage facilities and sites and outdoor confinement areas.”

In accordance with the O. Reg. 359/09, background review and site investigations were conducted to identify and

characterize all aquatic features within 120 m of the Project Location. These investigations determined each water

body’s REA water body status as per Section 1.1 of the O. Reg. 359/09. The results of this assessment are

provided in the Water Body Assessment Report (AECOM, 2017c). A total of 34 watercourses and drainage features

and two ponds were assessed and 16 of these water bodies were confirmed as REA water bodies. The results of

the impact assessment of the project on the identified REA water bodies can be found in the Water Body Report

(AECOM, 2016f).

4.3.1.2 Groundwater

An important environmental effect to consider is the potential for the Project to interfere with existing uses of a

water resource.

The following section provides an overview of the Hydrogeological Assessment and Effects Assessment Report

(AECOM, 2017a) for the Project. For further details please refer to the Hydrogeological Assessment and Effects

Assessment Report in Appendix C of the Design and Operations Report.

4.3.1.3 Physiography and Topography

The Project lies within the Chatham Flats, a sub-region of the St. Clair Clay Plains physiographic region (Chapman

and Putnam, 1984). The Chatham Flats is described as a low relief extensive clay plain that slopes gently to the

west toward Lake St. Clair. In the Municipality of Chatham-Kent, a shallow sand layer is found to overlie the

predominantly clay soils (Chapman and Putnam, 1984). According to MOECC water wells records, the sand layer

can be up to 5 m thick in certain areas.

Land use across the Study Area is dominated by a mixture of crop cultivation and livestock agriculture, which has

been made possible by the installation of dredged ditches and tile under-drains to provide satisfactory moisture

conditions within the imperfectly drained soils. Chapman and Putnam (1984) classify the soils of the Chatham flats

as considered highly fertile, producing cash crops in addition to corn and soybeans. Ground surface topography




within the Study Area is characterized as possessing low relief, with minor undulations commonly associated with

local surface water features. For Study Area, refer to figures in Appendix C (Hydrogeological Assessment and

Effects Assessment) in Design and Operations Report.

Bedrock Geology

Surrounding the Project, thick successions of Upper Devonian aged Paleozoic sedimentary rocks subcrop beneath

the overburden soils. The Project is underlain by bedrock of the Kettle Point Formation, which can be described

generally as a brown to black, laminated, organic-rich shale and siltstone (Armstrong, D.K., and Dodge, J.E.P.,

2007).

Depth to bedrock across the entire Study Area was assessed through a review of Drift Thickness mapping

published by the Ontario Geological Survey, as well as MOECC water well record information. Based on this

review, overburden thickness within the Study Area has been shown to range between approximately 13 m and

43 m, with an average thickness of about 24 m.

Overburden Geology

Thick overburden deposits consisting of both fine and coarse textured glacial sediments and fluvial deposits occur

across the Study Area. The Project is situated within an abandoned lacustrine plain that consists of numerous

alluvial features which were deposited in high level post-glacial and non-glacial lakes which historically occupied

the St. Clair basin. Where the Thames River entered the glacial lakes, deltaic sediments of sand and gravel were

deposited.

Groundwater Resources

Within the Municipality of Chatham-Kent, water for municipal supply is provided from both surface water and

groundwater facilities (Chatham-Kent, 2016) however there are no municipal surface water intakes and/or

groundwater supply wells physically located within the Study Area. Municipal water supply distribution mapping was

not available at the time of report preparation. It is assumed that the majority of the properties within the Project

Location are not serviced by a municipal water supply and therefore the primary potable water source is private

water supply wells owned and operated by individual property owners. Table 4-6 is a record of the wells within the

Study Area provided by MOECC. Available well records indicate that 38% of groundwater use in the Project

Location is for domestic purposes. Agricultural supply use (i.e., irrigation and livestock) accounts for 22% of the

MOECC water well records, followed by commercial and/or industrial (2%), and public sources (i.e., school) (<1%).

Approximately 32% of MOECC water well records did not specify the well use and therefore are classified as

‘Unknown’. Approximately, 6% of the MOECC water well records indicate the well is not used, accounting for

decommissioning records and dry wells.

monitoring and maintenance plan.

Remove construction debris from the site and stabilize it to prevent it from entering the nearby

water bodies.

Avoid construction during high volume rain events, as determined in consultation with an

Environmental Monitor, and significant snow melt/thaw events, where possible, and resume once

soils have been stabilized or mitigation measures have been installed (e.g., heavy-duty silt

fences, coir logs, or straw mats around any soil stockpiles) to avoid risk of erosion, soil

compaction or the potential for sediment release into nearby water bodies.

Monitor ESC systems frequently for effectiveness, repairing deficient controls in a timely manner and

using an adaptive management approach when deemed appropriate.

Time clearing, grubbing, and grading activities to avoid seasonally wet periods, where possible.

Develop a Flood Response Protocol (FRP) to deal with on-site flooding in order to mitigate any

possible effects to the aquatic environment.

The application of the ESC Plan and maintenance of ESC

systems will prevent impacts to water bodies from

increased erosion, sedimentation, and turbidity due to the

removal of vegetation. In addition, the removal of

vegetation will be localized.

Changes in water chemistry resulting

in decreased water quality by

accidental spills of oils, gasoline,

grease, and other materials.

Minimize water contamination

Minimize soil contamination.

Operate construction equipment (e.g., cranes, back hoes) in a manner that minimizes disturbance

to the water body banks and stays outside of the water body and bank area. Machinery should

arrive on site in clean condition.

Frequent checks and maintenance should ensure that no fluid leaks occur. Machinery must be

refuelled, washed, and serviced a minimum of 30 m away from all water bodies and other

drainage features to prevent any deleterious substances from entering a water body.

Store fuel and other construction related materials securely away from any drainage features and

locate construction staging areas 30 m away from any water body, where possible.

Develop a SPRP prior to commencement of construction that provides a detailed response

system to deal with events such as the release of petroleum, oils and lubricants or other

hazardous liquids and chemicals. Keep a spill kit on site at all times and train on-site workers in

the proper use of this kit and to be fully aware of the SPRP.

Remove construction debris from the site and stabilize it to prevent debris from entering the

nearby water bodies.

Remove and dispose of any waste generated from the site appropriately off-site according to

provincial standards.

Horizontal directional drilling should be executed at a depth that limits the potential impacts

associated with the possibility of a ‘frac-out’ (i.e., the escape of drilling mud and/or fluids into the

environment as a result of a spill, drilling tunnel collapse or rupture of mud to the surface due to

excessive pressure from an obstruction within the borehole). A minimum depth will be provided on

design drawings and will be included in discussions relevant agencies, where required.

Restrict construction equipment to designated, controlled vehicle access routes to minimize the

potential for soil compaction.

Potential impacts to a water body associated with the

unforeseen spill of drill fluid will be mitigated through the

application of a SPRP and an emergency ‘frac out’

response plan.

Emergency ‘frac-out’ response plan will mitigate any

potential impact to water bodies.

Changes in water quality are highly unlikely and related

only to spills. Following the SRP and locating machine

fuelling and maintenance activities away from water bodies

will prevent contamination of water bodies.

Conduct daily inspections of construction equipment for leaks/spills

Implement the following contingency measures in the event of a spill:


Install a spill collection pad for refuelling and maintenance.

Notify MOECC’s Spills Action Centre of any leaks or spills.

Assess and remediate affected soils and water by using a spill kit

kept on site.

Monitor daily to ensure proper cleanup is completed.

Implement any other general water quality parameters as required by

to MOECC Policy 2 standards for discharging to a waterbody

Soil compaction as a result of heavy

machinery and the stockpiling of heavy

materials (i.e., soils) reducing the

permeability of soils and their ability to

retain water during rain/snow melt events

resulting in an increase in surface water

runoff which could increase the erosion

potential and the amount of sediment

being transported into adjacent water

bodies. Soil compaction can restrict re-

vegetation of construction and temporary

lay down areas.

Increase in impervious surfaces and

increased surface runoff down a steep

slope (i.e., a valley, or steep side

slopes of municipal drains), resulting

from re-grading of land and resulting in

increased potential for erosion and

downstream sedimentation.

Minimize the increase of

impervious surfaces and

surface runoff.

Minimize soil compaction.

Time clearing, grubbing, and grading activities to avoid seasonally wet periods, where possible.

Operate construction equipment (e.g., cranes, back hoes) in a manner that minimizes disturbance

to the water body banks and stays outside of the water body and bank area.

Confine construction equipment to designated, controlled vehicle access routes to minimize the

potential for soil compaction.


Environmental Monitor and significant snow melt/thaw events, where possible, and resume once




If insufficient time is available in the growing season to establish vegetative cover, apply

overwintering treatments such as erosion control blankets, fibre matting, rock (i.e., large, clean

angular rocks) reinforcement/armoring or equivalent to contain the site over the winter period.

Previously vegetated areas (e.g. grassy lawns and roadsides) will be re-vegetated, where

required, using an appropriate seed mix.

Change in flow patterns, flooding, erosion and

sedimentation are highly unlikely following the application

of the ESC Plan.

The reduction of soil permeability and infiltration capacity

as a result of heavy machinery and stockpiling of heavy

materials is minimal, localized, and temporary in nature is

highly unlikely. Stockpiling of material and the use of heavy

machinery is expected to be localized and temporary in

nature.

Stockpiles of debris will be removed from the site and

stabilized according to the ESC Plan. Change in flow

patterns, flooding, erosion and sedimentation are highly

unlikely following the application of the ESC Plan.







Stockpiles of construction related

materials, such as soil, shrubs, trees

and root wads in or near a waterbody

can result in debris or sediment

entering the water body if the

stockpiles are not properly contained.

Minimize disturbance to local

drainage patterns and

flooding.

Minimize erosion and

sedimentation, and water

quality impairment.

Schedule construction activities near water (within 30 m) to occur within the low flow period of the

late summer months, where possible, to avoid or minimize impacts.

Remove construction debris from the site and stabilize it to prevent debris from entering the

nearby water bodies.

Remove and dispose of any waste generated from the site appropriately off-site according to

provincial standards.

Minor, isolated, short term dewatering

of shallow groundwater from

excavation areas required when

excavation intercepts an area of

shallow groundwater table conditions.

Minimize short term

dewatering activities when

possible.

Dewatering discharge rates should be evaluated as to not result in erosion and sedimentation to

receiving water body.

If discharging to a municipal storm sewer system, ensure that groundwater quality meets the

objectives of the municipal storm sewer by-law prior to discharge. To mitigate potential effects

associated with the discharge, sample for total suspended solids (TSS) prior to discharge to

ensure the water is suitable for discharge and will not result in an impact to the receiving water

body. If the groundwater is not suitable for discharge, identify alternate disposal locations or carry

out adequate treatment.

To mitigate potential effects associated with the discharge, sample for TSS prior to discharge to ensure

the water is suitable for discharge and will not result in an impact to the receiving water body. If the

groundwater is not suitable for discharge, identify alternate disposal locations or carry out adequate

treatment. The success of all mitigation will be verified though groundwater quality sampling.

Install an in-stream sediment filter (e.g., Siltsoxx or Filtersoxx) downstream of a water containment

structure so that dewatering discharge is dissipated (i.e., splash pads, sand bags, hay bales etc.)

which may require splitting discharge to more than one location.

The extent of dewatering will be localized and minimal.

Impacts to water levels due to dewatering activities are

highly unlikely. Monitoring water levels immediately

before, during and after dewatering activities will help to

mitigate any impacts.

Monitor water quality (TSS) prior to discharge, where required, during

construction.

Monitor end point of dewatering discharge for water quality and

erosion.

Completion of In-water Work

Requiring In-stream Dewatering and

the Construction of Temporary Dykes

or Cofferdams

Release of suspended sediment that

is carried downstream during the

installation and removal of temporary

structures.

Minimize erosion and

sedimentation, and water

quality impairment.

Limit in-stream construction time to a minimum and maintain a vegetative buffer zone, three

metres from the water’s edge, until immediately prior to in-stream excavation. To avoid

contamination of water, construction equipment is not permitted to travel along the bed of a

watercourse and fording of streams should not take place unless approved by MNRF and the

conservation authority.

Install an in-stream sediment filter (e.g., Siltsoxx or Filtersoxx) downstream of a water

containment structure so that dewatering discharge is dissipated (i.e., splash pads, sand bags,

hay bales etc.) which may require splitting discharge to more than one location.



Following completion of a water crossing, the stream channel must be restored to a state similar

to pre-existing conditions. All temporary structures and construction debris/materials must be

removed and the stream morphology must be reshaped to its original or approved configuration.

Bank stabilization, even if temporary, must occur within 10 days of stream bed back-filling and

the banks should be re-contoured to their original shape.

If required, perform in-water work in dry conditions. If this is not possible, short-term isolated

dewatering will be required. Prior to dewatering, isolate the work area with the installation of a

temporary water containment structure. The structure should form an impermeable enclosure that will

prevent debris and sediment from escaping into the surrounding water body. Construct a by-pass

channel to maintain flow through the water body and prevent back flooding, which could ultimately

overtop the water containment structure. Additional permits may be required for in-water work.

If in-water work is required (e.g., for culvert installation and or collector lines installation), adhere

to required timing windows confirmed through consultation with regulatory agencies.

If dewatering is required, isolate the work area and establish a by-pass channel to maintain flow

quantity through the water body.



Collect and relocate fish to a suitable location, preferably downstream and away from the

construction area, prior to surface water dewatering. This should be executed through the

development of a Fish Salvage Plan and by a qualified fisheries biologist.

The disruption of surface drainage patterns associated

with in-water works will be temporary and is not

anticipated to have residual impacts on surface water.

Working within the appropriate timing window will help to

mitigate any impacts to fish and fish habitat.

The release of excess suspended sediment downstream

is unlikely and may occur only during in water work.

Performing in water work in the dry and isolating the work

area will prevent increases in suspended sediment if in

water work is required.

Monitor end point of dewatering discharge for water quality and

erosion.

Daily erosion checks during discharge of water.

Monitor water quality (TSS) prior to discharge, where required,

during construction.

Other general water quality parameters as required by to meet

MOECC Policy 2 standards for discharging to a water body

Monitor by-pass channel, where applicable.

Perform daily checks of the channel to ensure it is functioning

appropriately and water is flowing through as designed.

Monitor to ensure that fish displaced as result of dewatering activities

are returned to the watercourse in good condition.

Consult with MNRF to determine additional contingency measures if

necessary.






Degradation of water quality from

contamination drilling frac-out.

Minimize disturbance to

aquatic habitat as a result of

potential frac-outs.

If in-water work is required (e.g., for collector lines installation), adhere to required timing

windows confirmed through consultation with regulatory agencies, including the MNRF.

Locate drilling entry/exit shafts beyond the top of bank, at a distance that allows the minimum

depth, as identified on design drawings, to be reached while below the water body. This distance

should be agreed upon with relevant agencies, where required.

Develop and implement an emergency ‘frac-out’ response plan including steps to contain,

monitor and clean-up in response to the event.

Potential impacts to a water body associated with the

unforeseen spill of drill fluid will be mitigated through the

application of a SPRP and an emergency ‘frac out’

response plan.

Emergency ‘frac-out’ response plan will mitigate any

potential impact to water bodies.

Monitor aquatic habitat at drilling locations, if required (i.e., potential

frac-out).

Continuous monitoring by an Environmental Monitor, during drilling

operations underneath a water body, to identify frac-out (if it occurs).

Vegetation Control and Increased Vehicle Use:

Degradation of water quality from contamination by oils,

gasoline, grease, and other materials due to accidental

Increase in surface runoff resulting from clearing of

vegetation, increase in impervious surfaces, and soil

compaction from vehicles accessing the site, resulting in

increased erosion and sedimentation.

Minimize erosion, sedimentation and turbidity

resulting from clearing of vegetation.

Minimize water contamination.

Store fuel and maintenance related materials at least 30 m away

from any drainage features, where possible.

Implement a SPRP to provide a detailed response system to deal

with events such as the release of petroleum, oils and lubricants or

other hazardous liquids and chemicals. A spill kit must also be kept

on site at all times and on-site workers must be trained in the use of

this kit and be fully aware of the SRP.

Develop an ESC Protocol that will minimize the potential for

operations related sediment release into nearby water bodies (ESC

Guideline).

Confine vehicles to designated controlled access routes to minimize

the potential for soil compaction.

Spills during the operational phase are rare. The

application of a SPRP will mitigate any potential

impact to water bodies.

The increase in impervious surfaces is minimal and

highly localized. Vehicles will be confined to

designated access routes.

The application of the ESC Plan and maintenance

of ESC systems will prevent impacts to water

bodies from increased erosion, sedimentation, and

turbidity due to the removal of upland riparian

vegetation, increased impervious surfaces, and soil

compaction.

No monitoring or contingency measures required.

4.4 Emission to Air, including Odour and Dust


The Project Location is dominated by agricultural production activities and typical farm practices, which include the

use of oversized machinery that are driven in fields as well as on rural, typically gravel, roadways. Periodic odours

in rural areas from activities like the spreading of manure as well as increased dust particulate are considered to be

normal nuisances associated with typical agricultural practices (Ontario Ministry of Agriculture, Food, and Rural

Affairs, 2005).



The Project activities associated with the site preparation and construction phase and the decommissioning phase

will lead to emission products, including but not limited to GHGs (e.g., methane, and carbon dioxide), nitrogen

dioxide, sulphur dioxide and suspended particles from vehicles and machinery operation. The emissions levels will

fluctuate through the various construction and decommissioning related activities, with access road construction /

reclamation, site grading, and preparation / reclamation of staging and laydown areas having the highest potential

for emissions because of increased construction or decommissioning equipment activities during this time. In

general these emissions will be temporary and localized.

No emissions of odours are anticipated during construction or decommissioning activities.

Table 4-12 identifies potential effects on air quality that could occur during the construction and decommissioning

phases of the Project and identifies mitigation strategies and a monitoring plan.

Operations

During the operation of the Project, maintenance activities have the potential to cause infrequent, localized and

short-term fugitive dust and emissions typical to the operation of motorized vehicles. These emissions are expected

to be considerably lower in magnitude than during the construction and the decommissioning activities.

No emissions of odours are anticipated during operations.

Table 4-13 identifies potential effects on air quality that could occur during the operations phase of the Project and

identifies mitigation strategies and a monitoring plan. Where monitoring determines that the mitigation measures

are not working as anticipated, contingency measures are described to address any adverse effects.

Review of proposed


4.5 Noise


As mentioned in the above section, land use within the Project Location is primarily agricultural and exposed to

existing farm practices. These practices include the operation of large agricultural machinery at off hours as well as

increased traffic in the region relating to the hauling and storage of crops. Periodic increased noise associated with

regular farm operations is considered to be a normal nuisance associated with typical agricultural practices (Ontario

Ministry of Agriculture, Food, and Rural Affairs, 2005).



The operation of heavy construction vehicles and temporary generators could also result in nuisance noise at

nearby residents or businesses. Noise may be highest during land clearing and other activities that involve

significant levels of material handling (e.g., aggregate laydown for access road construction and preparation for the

installation of underground collector lines).




Table 4-14 identifies potential effects from nuisance noise that could occur during the construction and

decommissioning phases of the Project and identifies mitigation strategies and a monitoring plan.

Operations

The operation of wind turbine generators and the electrical substation will generate noise that has the potential to

affect local residents. Table 4-15 identifies potential effects from noise that could occur during the operations phase

of the Project and identifies mitigation strategies and a monitoring plan.

4.6 Local Interests, Land Use and Infrastructure

Local interests, land uses and infrastructure were taken into consideration during the design phase of the Project.

The following section describes the results of the effects assessment for the operations phase of the Project.

Effects on agricultural use, adjacent residences and properties, roads, the local airport, and conservation areas

were included in this assessment. All turbines have been sited to meet or exceed MOECC’s required setbacks.


Land Use

The Project is located within the single tier Municipality of Chatham-Kent, Ontario. Chatham-Kent’s Official Plan

(2016) and Zoning By-law (2015) show that land uses in the Project Location are predominantly designated and

zoned for agricultural use. Other land uses within and adjacent to the Project Location include non-farm residential

uses on separate lots created through severances for farm retirement lots and surplus farm dwelling lots.

There is no record of site contamination within the Project Location which was confirmed through a review of the

MOECC’s Records of Site Condition (MOECC, 2016.).

Provincial and Local Infrastructure

As part of the REA process, Otter Creek will consult with the Municipality of Chatham-Kent and MTO to determine

what effects the Project might have on local services and infrastructure. Such issues may include, but are not

limited to, effects to underground water and wastewater infrastructure, roads and traffic, emergency management

and response, and building code requirements.

Adjacent Businesses and Properties

A Property Line Setback Assessment has been prepared to address Section 53 of O. Reg. 359/09, as amended,

(see Appendix D of the Design and Operations Report). This section of the regulation requires the identification of

any impacts to businesses, infrastructure, properties or land use activities resulting from a turbine location being

proposed at a distance equal to or less than the hub height of the turbine from an adjacent property line. Eleven

turbines were identified to require assessment due to their proximity to adjacent property lines. The Property Line

Setback Assessment confirmed that adverse impacts to the adjacent parcels may include damage to field crops in

the unlikely event of a turbine failure. However, this potential impact already exists at a height equivalent to the

height of turbine base to top of hub and is not increased by a decreasing this setback.

Local Airport

The Chatham-Kent Municipal Airport is located approximately 37 km away from the southern extent of the Project

Location. Otter Creek submitted a completed Land Use Proposal Submission Form to NAV Canada to receive input

if the Project layout will cause interference or conflicts associated to Aviation Safety in the area. NAV Canada

confirmed there are no objections related to the Project.

Telecommunication and Weather Towers

Otter Creek has provided Project notices to telecommunication companies in the area to provide details on the

Project. To date, Otter Creek has not received any concerns from these companies.

The closest Environment Canada weather radar tower is located in Exeter, Ontario and such, the Project will not

have any impact on the operations of the weather radar tower.




Conservation Areas

The Project Location is situated within the boundaries of SCRCA. No conservation areas are located within the

Project Location.

Local Roads and Traffic

The Project Location map (Figure 1-1) displays existing local and provincial roads in proximity to the Project

Location. As part of the REA process, Otter Creek is continuing consultation with the Municipality of Chatham-Kent

to determine what effects the Project might have on local services and infrastructure.

Aboriginal or Treaty Interests

To ensure aboriginal or treaty interests were considered, Otter Creek submitted the appropriate documents to the

MOECC in order to receive the Aboriginal Contact List. MOECC confirmed that the following communities may

have an interest in the Project:

Walpole Island First Nation;

Aamjiwnaang First Nation;

Oneida Nation of the Thames;

Chippewas of the Thames First Nation;

Chippewas of Kettle and Stony Point First Nation;

Caldwell First Nation;

Moravian of the Thames; and

Munsee-Delaware Nation.



There will be a temporary loss of agricultural land during construction and installation activities as a result of

temporary Project components, laydown areas and the construction working areas. However, these areas will be

small relative to the total land area within the CDA, and these lands will be returned to a state similar to pre-existing

land use after construction and installation activities are completed, unless otherwise agreed upon with the

landowner. During the construction of access roads and crane mats, as well as the installation of collector lines,

there is the potential to disturb existing agricultural drainage tiles. In the event that a drain would be severed or

damaged, the affected drain will be capped and repaired as soon as reasonably possible to avoid negative impacts

to existing drainage patterns.

The road capacity and local traffic may also be affected during construction related activities. The delivery of

construction equipment and project infrastructure, and construction of new turbine access roads could result in a

temporary increase in slower moving traffic volume on local roads. Construction related activities next to or in road

easements could also result in temporary disruptions to the flow of traffic on some local roads. The changes in

traffic volume are expected to be minimal and no appreciable change to traffic flow is anticipated as a result of the

Project.

Table 4-16 identifies potential effects on land use and infrastructure including local roads that could occur during

the construction and decommissioning phases of the Project and identifies mitigation strategies and a monitoring

plan.




Operations

During the operation of the Project, the road capacity and local traffic could be affected if maintenance activities

involve the replacement of a major wind turbine generator component, since specialized equipment (e.g., cranes)

may be required. The delivery of specialized equipment could result in a temporary increase in slower moving traffic

volumes on local roads. Any maintenance activities adjacent to or in road easements could also result in temporary

disruptions to the flow of traffic on some local roads.

Table 4-17 identifies potential effects on local interests, land use and infrastructure that could occur during the

operations phase of the Project and identifies mitigation strategies and a monitoring plan.

construction activity, where appropriate.

No significant adverse effects to local roads and traffic are

anticipated during construction and installation activities

4.7 Other Resources


4.7.1.1 Landfills

MOECC’s Large Landfill and Small Landfill Sites records (MOECC, 2014a and MOECC, 2014b) were used to

confirm that there are no active landfills within the Project Location – the closest active landfill being approximately

36 km away. Therefore, no effects on landfills are anticipated.

4.7.1.2 Aggregate Resources

No aggregate pits or quarries have been identified through review of the MNRF’s Pits and Quarries Online

database tool (MNRF, 2015a). Therefore, no effects on aggregate resources are anticipated.

4.7.1.3 Forest Resources

Based on the MNRF’s Sustainable Forest Licences (SFL) database (MNRF, 2015b), there are no SFLs within the

Project Location. Therefore, no effects on forest resources are anticipated.

4.7.1.4 Petroleum Resources

Otter Creek has prepared a Petroleum Resources Report which was completed by a licensed engineer in Ontario.

The report concludes that through continued consultation with oil and gas companies, the Project can be

constructed to avoid impacts to oil and gas resources. It is anticipated that the report will be submitted to the MNRF

in winter 2017.

4.8 Public Health and Safety

4.8.1 Potential Effects

4.8.1.1 Stray Voltage

Otter Creek will ensure that the electrical design conforms and complies with relevant electrical safety standards.

Hydro One has established procedures in place to address stray voltage for off-farm and on-farm sources.

4.8.1.2 Structural Hazards

In the unlikely event of structural collapse or blade detachment, equipment will fall within a very small diameter due

to the weight of the wind turbine components. Wind turbine siting for the proposed Project will meet, at a minimum,

the setback distances from roads (blade length plus 10 m) and non-participating residences (550 m) as outlined in

O. Reg. 359/09, as amended.

A Property Line Setback Assessment (Appendix D of the Design and Operations Report) was conducted in

accordance with O. Reg. 359/09, as amended, to identify the proposed turbines located within the distance

equivalent to the height of the tower from base to top of hub, of an adjacent property line.




Based on the analysis of the eleven turbines requiring justification for the reduced property line setback, there are

no anticipated adverse impacts for the reduced setbacks once the standard preventative measures based on best

management practices have been applied.

4.8.1.3 Ice Throw

Ice throw and ice shed refer to situations where during specific weather conditions, ice may form on wind turbines

and may be thrown or break loose and fall to the ground (Chief Medical Officer of Health (CMOH), 2010). Wind

turbines for the proposed Project will be located on private property and meet, at a minimum, the setback distances

from non-participating residences (550 m) and roads (blade length plus 10 m) outlined in O. Reg. 359/09, as

amended. During the operation of the Project, sensors located on the turbines will detect ice build-up and turbines

will be shut down if deemed unsafe by Otter Creek during operation.

4.8.1.4 Low Frequency Sound, Infrasound and Vibration

Wind turbines have the potential to emit low frequency sound, infrasound and vibration. Low frequency sound

commonly refers to sound at frequencies between 20 and 200 Hz; infrasound commonly refers to sound at

frequencies below 20 Hz (i.e., below the threshold of human perception). Although generally considered inaudible,

infrasound at high-enough sound pressure can be audible to some people (CMOH, 2010 and McCunney et al.,

2014). The “Potential Heath Impacts of Wind Turbines Report” (CMOH, 2010) identified that infrasound and low

frequency sound from modern wind turbines were found to be well below the level where known health effects

occur (50 to 70 dB) in studies of wind turbine noise. McCunney et al. concluded that “infrasound and low-frequency

sound do not present unique health risks”, and “annoyance seems more strongly related to individual

characteristics than noise from turbines” (2014, pp. 108).

4.8.1.5 Electric and Magnetic Fields

Concerns surrounding electromagnetic fields (EMFs) have been raised during other REA consultation processes.

EMFs are a combination of invisible electric and magnetic fields. They occur both naturally (e.g., light is a natural

form of EMF) and as a result of human activity. Nearly all electrical and electronic devices emit some type of EMF

(CMOH, 2010). The generation of electrical fields from underground and above-ground electrical collector lines

from the Project will be shielded by line insulation and the surrounding ground but will still generate magnetic fields.

Associated magnetic fields will be similar to other buried distribution lines in Ontario.



Effects on public health and safety during construction have been described in Section 4.4 (Air, Odour and Dust),

Section 4.5 (Noise), and Section 4.6 (Local Interests, Land Use and Infrastructure).

Operations

To minimize or avoid effects on public health and safety, the turbines are sited according to setback distances

outlined in O. Reg.359/09 and as described above.

Table 4-18 identifies potential effects on public health and safety that could occur during the operations phase of

the Project and identifies mitigation strategies and a monitoring plan.

4.9 Areas Protected under Provincial Plans and Policies

The REA requires a determination as to whether the Project is being proposed in any of the following protected or

plan areas:

Protected Countryside or Natural Heritage Systems in the Greenbelt Plan;

Oak Ridges Moraine Conservation Plan Areas;

Niagara Escarpment Plan Area; or

Lake Simcoe Watershed Plan Area.

The Project is not proposed in an area within the jurisdiction of the plans noted above. As such, there will be no

effects on these areas as a result of the Project.




5. Summary and Conclusions

Field work and data collection were undertaken to determine the potential effects of this Project during the

construction, operations and maintenance and decommissioning phases. Mitigation measures to manage these

potential effects have been identified and monitoring and contingency plans proposed to ensure effects are

minimized.

Significant adverse effects have been avoided through careful site selection, facility layout planning and adherence

to all regulatory requirements.

The overall conclusion is that this Project can be constructed, operated, maintained and decommissioned

without any significant adverse net effects to the environment. Post-construction monitoring, including

effects on wildlife such as birds and bats, will be undertaken to confirm this conclusion.
