1. Introduction 1.1 Background

This Construction Plan Report (hereinafter referred to as “the Report”) is required as a part of an application for all renewable energy Projects that must submit a renewal energy application (REA) under Ontario Regulation (O. Reg.) 359/09 – Renewable Energy Approvals Under Part V.0.1 of the Act.

The Project is proposed to be constructed on private land owned by German Solar Corporation (GSC) and will be situated on an abandoned and discontinued rail line corridor. MNO Solar FIT 4 LP has entered into an option to lease agreement with GSC for the purposes of building, operating, and maintaining the Project.

The proposed Project will use solar photovoltaic (PV) technology to generate electricity. The monocrystalline or polycrystalline PV panels will be mounted on structural aluminum or galvanized steel racking tables in single, double or triple rows. Each rack is in a fixed tilt-adjustable position, facing south and angled between 15° and 55° to the horizon. The rows of racking tables are supported by vertical structural steel posts that are founded in either concrete slab on grade, driven piles or buried foundations in the ground to a depth below the frost line, at least 1.2 m. Electricity generated by the PV panels will be converted from direct current (DC) to alternating current (AC) by inverters, and subsequently stepped-up (via a transformer) to 27.6 kV in order to connect to the existing Hydro One Networks Inc. (HONI) distribution system. The transformer will be located within the proposed panel location on a concrete transformer vault. A network of underground DC cabling will be required from the termination point of the PV array to the inverters which will then convert the DC electricity to AC. A network of underground AC cabling will be required from the inverters, to connect the PV array to the HONI distribution system.

Construction of the Project will commence once the REA and other required permits have been obtained. The construction period is estimated to be approximately 3 to 6 months in duration, with Project commissioning anticipated on or before Fall 2019.

1.2 Objective and Scope The Construction Plan Report (hereinafter referred to as “the Report”) is required as a part of an application for all renewable energy Project that must submit a REA under Ontario Regulation (O.

2.2.5 Security Gate, Fencing and Lighting The facility, with the exception of the underground Connection Line will be gated and fenced, with additional security measures installed as required by the Proponent. The fence design includes a chain-link fence, approximately 2 m high which may have barbed wire. The site will be under continual surveillance by the supervising construction staff when on-site. In addition, 24-h on-site security will be utilized.

For security and maintenance purposes, task-specific lights will be installed on the Project Location during construction near the entrance to the facility. Additional motion sensor security lighting may be installed.

2.2.6 Fire Control Plan The Project is not likely to be a source of fire, or a contributor to spreading an existing fire. However, there is some rare potential fire hazard due to electrical faults at the PV modules and ancillary equipment. The Contractor will prepare a fire control plan for the construction activities. It will include establishing procedures for specific types of likely fires, training staff accordingly, and keeping fire protection equipment on site.

2.2.7 Drainage Based on site visits and preliminary assessments, the existing drainage system appears to be adequate for the Project. All waterbodies and drainage features have been identified within the Water Body Report (Hatch, 2017b).



Report

H353010-00000-121-066-0068, Rev. 0, Page 2-6


2.2.8 Landscaping and Vegetation The Contractor will determine whether any alterations to the existing landscape are required for construction purposes. If required, a grading plan will be produced.

Areas within the Project Location, with the exception of roads and drains, may be covered with a suitable, locally grown, low maintenance vegetation. This will aid in the prevention of soil erosion and the invasion of non-native plant species as well as present a natural appearance.

2.2.9 Power and Communication During construction, electrical power will be provided by portable diesel generators for small equipment and hand tools supplied by the Contractor. For temporary and permanent use, the Proponent may also obtain an electrical power supply feed and communication line from the local utilities, to provide the needed electricity for the construction offices, security lighting, and other purposes.

2.2.10 Temporary Water Takings No temporary water takings from a ground or surface water source will be required for construction. In order to meet the water demand during construction, the Contractor will be required to supply water by truck. The water will be used for construction, sanitary, and dust control purposes.

2.2.11 Materials/Waste Generated At Or Transported From the Project Location Typical construction wastes, such as broken PV modules, electrical wires, wood, and miscellaneous packaging materials, will be managed and disposed of in accordance with local, provincial, and federal regulations during construction. Recyclable waste will be transported to the closest recycling centre at the expense of the Contractor. As required, the Contractor will supply and maintain on-site portable self-contained toilets.

2.3 Construction Phases

2.3.1 Phase 1 – Site Preparation Site preparation refers to all necessary activities prior to the construction of foundations and installation of the PV modules. It includes surveying/staking, site clearing and grubbing, surface grading, construction of access roads, installation of security gate and fencing. Appendix A contains a conceptualized depiction of the site plan and the proposed Project facility that is discussed throughout this report. In addition, Appendix A depicts the proposed facility components including the access roads, solar PV module arrays, inverter/transformer clusters and the connecting electrical line. Setback distances from identified significant natural features and waterbodies are also shown. For additional information regarding the design and operations of these components, please refer to the Design and Operations Report (Hatch, 2017a).



Report

H353010-00000-121-066-0068, Rev. 0, Page 2-7


2.3.1.1 Site Survey and Staking A registered Ontario land surveyor will provide a site survey and will stake the exact location of the site perimeter for fencing and access road layout. As part of this work, any buried utilities, infrastructure and their associated easements as well as any designated environmental features (e.g., waterbodies, woodlands, etc.) and their associated setbacks will be demarcated and protected by means of staking, flagging, fencing or signage to prevent any intrusion into these areas by construction vehicles.

2.3.1.2 Site Clearing and Grading The proposed Project Location contains hedgerows and scattered trees. Some of the hedgerows and trees will be cleared in order to install PV modules and avoid shading or blocking the sun on the PV panels.

Minor grading of the railway bed may be required.

2.3.1.3 Access Roads Access roads for the Project will use the existing lanes from the former railway bed. New access lanes may be required where the existing railway bed is not sufficient for access lane use. Where the existing rail bed is less than 5 m wide or is insufficient for an access lane, it will be widened to allow for transport using gravel sufficient for lane underlayment. The minimum thickness of the access road granular base and top course material will be at least 30 cm. Ditches and culverts will be constructed, if necessary, to maintain site drainage. Erosion and sedimentation control measures (e.g., silt fence barriers, etc.) will be installed if needed.

2.3.1.4 Construction Staging/Laydown Area Construction laydown will occur on the property, immediately adjacent to the proposed location of the PV arrays. The staging area will include construction offices, washrooms, first aid station, parking, construction equipment, material and plant storage/laydown area, and an unloading/loading area. Modular trailers will be used for the construction offices, washrooms and first aid station. Washrooms (portable toilets) will be maintained daily during construction. Following substantial completion (Project in service), the temporary facility will be removed from the site.

2.3.1.5 Sediment and Erosion Controls Prior to any vegetation removal, clearing and/or grading activities, sediment and erosion control measures (e.g., silt fence barriers and rock flow check dams) will be installed in accordance with a Sediment and Erosion Control Plan to be prepared for the Project. Additional measures will be installed as required for specific Phase 2 construction activities, discussed in Section 2.3.2. All sediment and erosion control measures will remain in place throughout the construction period and will be routinely inspected and maintained by the Contractor.

2.3.2.2

Tree Cutting and Vegetation Removal To construct the Project, minor tree and vegetation removal will be required within the Project Location. Tree cutting would be conducted using chainsaws. Stumps, roots and brush vegetation removed using an excavator or small bulldozer. During the clearing activities, merchantable timber, non-merchantable timber (e.g., firewood) and other cleared vegetation will be temporarily stockpiled. This material would be loaded on trucks and taken away by the buyer (i.e., merchantable timber), chipped for off-site composting or disposal, or used on-site as biodegradable erosion protection matting for exposed soil areas.

All relevant tree-cutting approvals that may be required by the Ministry of Natural Resources and Forestry (MNRF) will be obtained for the Project.

Surface Drainage Alterations to land topography will be limited to minor grading of the railway bed, as required. Accordingly, alterations to the existing surface drainage patterns are not expected as part of the construction and operation of the Project.

Phase 2 – Construction and Installation Construction and installation of the Project consists of installation of the transformer vault, installing structural supports for the solar PV modules (structural aluminum or galvanized steel racking tables in single, double or triple rows), installing the electrical cabling, installing the inverters, transformers and associated electrical equipment and installing the electrical distribution lines from the transformer to the local distribution lines.

Inverter Building and Electrical Equipment Foundations Foundation construction for electrical equipment comprises of excavation and removal of in situ material, placement of granular material, formwork, reinforcing steel, grounding, and placement of cast-in-place concrete pads. PV modules will be mounted on structural aluminum or galvanized steel racking tables in single, double or triple rows. The rows of racking tables are supported by vertical structural steel posts that are founded in either concrete slab on grade, driven piles or buried foundations in the ground to a depth below the frost line, at least 1.2 m.

Ready-mix concrete will be delivered by transit mixer truck from a local supplier.

Trenches for Cable and Instrumentation Control A network of underground DC cabling, or cable trays will be required from the termination point of the PV array to the inverters which will then convert the DC electricity to AC. A network of underground AC cabling may be required from the inverters, to connect the PV array to the HONI distribution system. In all cases, a simple trenching device or directional boring will be used to install the underground cables.



Report

H353010-00000-121-066-0068, Rev. 0, Page 2-9


Where necessary, conduits, as approved by the electrical safety code, of suitable diameter will be provided to cross underneath access roads. Where necessary, high density polyethylene (HDPE) conduits will be installed beneath road crossings to house and protect the cables.

2.3.2.3 Structural Support It is expected that the pads for the racking tables, transformers and inverters may be concrete slab-on-grade. The PV panels will be installed on fixed racking structures assembled on site. Modules will then be mounted on the structural support system. Lifting will be done by a small crane.

2.3.2.4 Solar Modules Solar modules will be hand-mounted on the supporting structure by PV installers.

2.3.2.5 Electrical System PV modules are proposed to be arranged in several pods, with inverters at the center of the entire array. The nameplate capacity of each module in the array will be approximately 325 to 425 Wp.

Modules will be strung together in strings, which will be brought to combiner boxes. From each combiner box, a single run of DC conductor will be brought to an inverter. The Project will have approximately 9 inverter stations that include 1 - 60 kW inverter each. These inverters will convert the DC power collected into AC power and this will be stepped up by a transformer central to the inverters to a planned voltage of 27.6 kV. Power will then be run underground to the nearest Hydro One owned distribution line and switched onto the HONI distribution network. Power collection will be by underground cabling. These cables will be buried at a minimum depth of 915 mm below grade, as is required by the Ontario Electrical Safety Code. The cables will be laid in a trench with a layer of sand above and below, and the trench will then be filled in with the original local material or imported. There will also be a caution tape buried in the trench halfway between the ground and the buried cables. After filling, the trenches will be graded to bring the land back to its original contours. This will restore the natural drainage prior to the development and will have minimum impact to the local flora and fauna. Where trenching is not possible due to encountered rock or other reasons, above ground cable trays may be used. The Connection Point is presented in Appendix A.

2.3.3 Phase 3 – Testing and Commissioning Testing and commissioning will be performed on the installation prior to start up and connection to the power grid. Solar modules, inverters, cabling, will be checked for system continuity, reliability, and performance standards. If problems or issues are identified, modifications will be made prior to start up.

2.3.4 Phase 4 – Site Restoration Site restoration will occur during the final stages of Project construction and installation activities. The main objective will be to re-instate the area to the original pre-construction condition, such as the ecosystem, vegetation, and drainage, where possible. All construction material, equipment and waste will be removed from the site. Site restoration will be undertaken, as required.

3. Environmental Effects This section describes the potential negative environmental effects that could occur during the construction and installation activities associated with the Project. All construction and installation activities are expected to occur at the Project Location, however, potential environmental effects are considered within 300 m of the Project Location. Information on the existing baseline conditions of the natural heritage and water body features can be found in the following documents:

• Natural Heritage Assessment Report (Hatch Ltd., 2017c)

• Water Assessment Report (Hatch Ltd., 2017b)

• Archaeological Assessment Report (The Archaeologists Inc., 2017)

• Heritage Assessment Report (The Archaeologists Inc., 2017).

Potential environmental effects are addressed by resource below.

3.1 Topography Based on the preliminary information, no major earth excavation, filling or regrading works are anticipated that would result in significant alteration to the existing topography. As part of the site preparation activities, some infilling of low-lying areas is expected, followed by general surface grading and contouring where required. Soils may be excavated for the construction of foundations and trenches will be dug for the buried cables. In both cases, these excavations will then be backfilled and leveled to match the existing grade, resulting in no impacts to topography. There will be no impacts to topography for lands adjacent to the Project Location since no landform alterations will occur on adjacent lands.

3.2 Soils Construction activities could potentially result in negative effects on soil, including vegetation removal, minor site grading, stockpiling of materials and heavy equipment uses. Accidental spills from some of these activities could also impact the soil. These activities could potentially result in negative effects, as discussed below, on soil quality and loss of soils due to erosion.

• Excessive soil compaction could inhibit vegetation growth by impeding root penetration within the soil, reducing aeration, and altering moisture intake (i.e., decreased infiltration due to decreased pore space within the soil structure) (DeJong-Hughes et. al., 2001). Decreased water infiltration into the soil could also potentially result in an increase in surface runoff which could increase soil erosion.

• Vegetation removal and excavations have the potential to increase soil erosion due to exposure of soil to the effects of runoff or wind.



Report

H353010-00000-121-066-0068, Rev. 0, Page 3-2


Potential adverse effects on soils due to accidental spills are discussed in Section 3.17.

3.3 Groundwater No significant negative effects to the local groundwater regime or the availability of groundwater are expected as no significant changes to groundwater conditions are expected. Dewatering of excavations will not be required for the support foundations and, therefore, no significant effects to groundwater conditions are expected.

Groundwater quality could be impaired as a result of contamination from accidental spills during construction (see Section 3.17), and similar to activities that occur on typical farms throughout Ontario.

3.4 Surface Water Quality Surface water quality of the tributaries located on and within 300 m of the Project Location could potentially be impaired during construction by increased turbidity resulting from

• erosion/sedimentation of excavated or exposed soils

• erosion caused by increased runoff from impervious or less pervious areas (e.g., concrete slabs, access roads), or

• deposition of fugitive dust.

These effects are temporary in nature and will result in only short-term minor impacts to the waterbodies in the vicinity of the Project Location.

Mitigation measures to address impacts to surface water quality are described in Section 4.3.

Potential adverse effects to surface water quality as a result of accidental spills are discussed in Section 3.17.

3.5 Aquatic Habitat and Biota Installation of solar modules will not have any direct adverse effects on aquatic habitat and/or biota, since no construction of solar modules will occur within 30 m of the average annual high water mark of any of the watercourses or the seepage area on or adjacent to the Project Location.

However, adverse effects on aquatic habitat and biota in local tributaries could occur due to construction activities. These activities could potentially result in adverse effects due to the erosion and sedimentation on the Project Location which could then lead to sediment in the watercourses.

In addition, negative effects to aquatic habitat and/or biota could potentially occur as a result of changes in surface water quality (see Section 3.4) and/or sedimentation due to wind or water erosion of adjacent soils. Increased turbidity could affect biota (e.g., clogging of gills, alterations in behaviour, smothering of incubating eggs). Sedimentation within waterbodies



Report

H353010-00000-121-066-0068, Rev. 0, Page 3-3


could also adversely affect aquatic habitat by infilling of interstitial spaces in areas with rocky substrates.

Mitigation measures to address these potential adverse effects are described in Section 4.4.

Aquatic biota could also be negatively affected by accidental spills during construction (see Section 3.17).

3.6 Vegetation There will be some minor removal of natural vegetation required for the Project. This represents a minor loss of natural vegetation from the vicinity of the Project Location.

Vegetation communities in the vicinity of the Project Location may also be impacted by dust deposition on leaf surfaces, resulting in minor impairment of growth. These effects are temporary in nature and will result in only short-term minor impacts to vegetation communities adjacent to the Project Location. Mitigation measures to address these impacts are described in Section 4.5.

Vegetation could also be damaged as a result of accidental spills which are addressed in Section 3.17.

3.7 Wildlife Impacts to wildlife could occur as a result of loss of habitat, disturbance from construction activities, or incidental mortality as a result of collision with construction vehicles.

There will be some minor loss of habitat on woodlands and hedgerow communities associated with the construction of the Project, but the majority of the site will remain suitable for use by wildlife species that would have been present prior to construction. Further, the amount of hedgerow and woodland habitats removed when compared with that available in the local area is considered to be negligible.

The presence of the construction workforce and operation of construction machinery on site will result in avoidance of the Project Location by species intolerant of these types of disturbances. Given the existing disturbance present in the area from the existing agricultural operations and residential areas nearby, it is not anticipated that there will be a significant avoidance of the area.

The movement of construction machinery across the site has the potential to result in the incidental take of wildlife species as a result of collisions with moving vehicles. Machinery operating on site will be travelling at low speeds and, therefore, the potential for incidental take is considered low, and likely restricted to species of small mammals and reptiles/amphibians that may be unable to rapidly move away from oncoming machinery.



Report

H353010-00000-121-066-0068, Rev. 0, Page 3-4


These effects are temporary in nature and will result in only short-term minor impacts to wildlife communities on and in the vicinity of the Project Location. Mitigation measures to address these impacts are described in Section 4.6.

3.8 Air Quality and Noise Dust may become airborne from vehicular traffic, heavy machinery use, and soil moving activities. Dust in the air can have a range of effects including, but not limited to

• impacts on human health as a result of irritation to lungs, eyes, etc., ingestion/inhalation of potential contaminants which could impact construction workers or nearby residents

• impacts on surface water quality and aquatic habitat if the dust is deposited into waterbodies

• impacts on vegetation if heavy dust loads build up on photosynthetic surfaces, thereby resulting in mortality of the plants.

In addition to impacts from dust, a variety of construction, haulage and personnel vehicles, as well as portable generators, will be used on site during the construction period. The use of this equipment will result in exhaust emissions containing, among other emissions, carbon monoxide, nitrogen oxides and sulphur oxides. Operation of this equipment will result in some minor decrease in air quality in the immediate vicinity of operating equipment. This effect, however, will be temporary in nature and emissions would be expected to dissipate following the equipment being shut down or its movement out of the affected area.

Construction and installation activities have the potential to result in increased noise levels on and within the vicinity of the Project Location. Noise emanating from the Project Location could disturb both the local sensitive receptors in the vicinity of the Project Location and local wildlife populations.

Both of these effects are temporary in nature and will result in only short-term minor impacts on local air quality and noise levels. Mitigation measures to address these impacts are described in Section 4.7.

3.9 Traffic Minor increases in traffic volumes and equipment delivery to the Project Location and temporary disruption along routes utilized by construction vehicles may result in occasional, minor delays to local community traffic flow during the construction period. This potential negative effect is most likely to affect the local area road users in the vicinity of the Project Location, as opposed to resulting in an inconvenience to a wider, regional area. Mitigation measures to address these impacts are described in Section 4.8.



Report

H353010-00000-121-066-0068, Rev. 0, Page 3-5


3.10 Municipal Roadways The use of municipal roadways by heavy construction vehicle traffic may result in some minor roadway damage during the construction of the Project. The magnitude of this potential negative effect will correspond directly with the proximity to the Project Location. Most damage would be expected to roads which are highly travelled by construction traffic, especially in the vicinity of the construction vehicle entrances to the Project Location. Mitigation measures to address these impacts are described in Section 4.9.

3.11 Public and Construction Site Safety Construction of the proposed development poses potential public and construction site safety concerns in the vicinity of the Project Location. Potential impacts include injury from construction equipment or activities. Mitigation measures to address these impacts are described in Section 4.10.

3.12 Waste Management Construction activities will likely result in the generation of recyclable material, as well as construction and sanitary waste. Generation of such material will occur within the Project Location and wastes and recyclables will be transported to the nearest approved facility for disposal or recycling. Mitigation measures to address these impacts are described in Section 4.11.

3.13 Land Use Lands within the Project Location are part of a former railway corridor and not currently known to be in use.

3.14 Protected Properties No protected properties, as defined in Section 19(1) of O. Reg. 359/09, exist on or adjacent to the Project Location. Therefore, no adverse effects on protected properties will occur.

3.15 Built Heritage and Cultural Heritage Landscapes A Heritage Assessment report has been completed in order to determine if there are any potential negative impacts by the Project on any Heritage features. The Heritage Assessment found that the Project will not negatively affect local heritage resources and recommended that the Project be released from further heritage concerns.

3.16 Archaeological Resources A Stage 1 Archaeological Assessment report has been conducted and did not identify any archaeological resources within the Project Location. The report recommends that no further archaeological assessment of the Project Location is required.

Following the Archaeological Assessment of the Project there remains a potential to uncover deeply buried heritage or archaeological resources (including human burial sites) which would not have previously been identified. In this instance, the Ministry of Tourism, Culture



Report

H353010-00000-121-066-0068, Rev. 0, Page 3-6


and Sport (MTCS) has specified mitigation that must be undertaken in the event of discovery of human remains or other archaeologically or culturally significant material. These mitigation measures are discussed in Section 4.12.

3.17 Spills Spills of petroleum hydrocarbon materials from vehicles/equipment operating on site, such as fuel or hydraulic oils, or spills of concrete materials from concrete trucks, could occur during the construction process. Spills may occur as a result of leakage from vehicles/equipment due to malfunction, leakage from storage areas (if such materials are stored on site) as a result of weakness in the storage equipment, improper handling techniques, and/or improper refuelling techniques. Spills of these materials could result in the following negative effects

• contamination of soils, surface water, and groundwater with materials inhospitable to the promotion of biological life

• uptake/ingestion by, or coating of, vegetation species or terrestrial and aquatic biota resulting in senescence or individual mortality.

The extent of these effects is highly dependent on the magnitude and location of the spills (i.e., larger spills or those in proximity to sensitive areas are anticipated to potentially have greater effects). The effectiveness of the spill response has a strong bearing on the scale of potential impact. Spill response measures are discussed in Section 4.13.

3.18 Contaminated Surficial Soils Given the former use of the Project Location as a railway line, the presence of soil contamination for metals, polyaromatic hydrocarbons (PAHs), and petroleum hydrocarbons (PHCs) particularly in surface soils are anticipated. Surficial soil concentrations above the application site condition criteria further confirmed contamination at the property as found within the Phase II Environmental Site Assessment conducted in September 2015 by SLR.

Disturbance of contaminated soils may occur as a result of minor grading activities, construction of ditches or culverts, if required, excavation related to the construction of buried foundations, if required, and trenching related to Connection Line installation.

Ground disturbance could result in the following negative effects

• minimal risks to health and safety of workers as well as members of the public

• contamination of surface water and groundwater

• uptake/ingestion by, or coating of, vegetation species or terrestrial and aquatic biota resulting in; senescence or individual mortality.

Mitigating measures are discussed in Section 4.14.

4. Proposed Mitigation Measures The following sections detail the proposed mitigation measures to prevent or minimize the potential negative environmental effects discussed in Section 3. Three types of mitigation measures were included and documented where applicable

• modifying the types of construction activities

• installing treatment technologies (e.g., erosion and sedimentation control measures)

• changing the construction schedule.

Information on mitigation measures with respect to significant natural heritage features and water body features can be found in the following documents

• Natural Heritage Assessment Report (Hatch Ltd., 2017c)

• Water Assessment Report (Hatch Ltd., 2017b).

Mitigation measures are addressed by resource below.

4.1 Soils As identified in Section 3.2, soils on and in the vicinity of the Project Location may be negatively affected as a result of construction and installation activities. Negative effects were documented with respect to soil displacement, soil quality and sedimentation/erosion processes. Mitigation measures are identified below in consideration of these areas.

Disturbed areas will be visually monitored for evidence of rutting or flattened areas beneath stockpiles. Restoration efforts (e.g., discing or other soil loosening methods) will be undertaken, as required, to prevent impacts due to excessive amounts of compaction.

In order to prevent mixing of topsoil and sub-soils (if encountered), these materials will be stored separately, where excavation is required. The depth of topsoil stockpiles is to be limited to the greatest extent possible, with depths preferably restricted to <1 m. Stockpiling to depths >1 m may result in adverse effects on the health of the soils at the base of the stockpile by promoting the generation of anaerobic conditions (Harris and Birch, 1989; cited in Strohmayer, 1999).

Preventing erosion from occurring will be the primary goal of a Sediment and Erosion Control Plan, to be prepared by the Contractor. The main mitigation measures that will form the basis for the sediment and erosion control plan will include the following:

• Erosion and sediment control measures to be placed throughout the Project Location, as required, to minimize the potential for erosion and sedimentation. This will include, at minimum, silt fencing installed around the Project work areas where there is potential for



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-2


off-site sediment transport, and in the vicinity of drainage features on and adjacent to the Project Location. All erosion and sediment control measures are to be installed and maintained in accordance with Ontario Provincial Standards Specification (OPSS) 577.

• All necessary erosion and sediment control measures must be in place prior to the start of any earthworks, and are to remain in place until areas disturbed during construction have been stabilized.

• An adequate supply of erosion (e.g., geotextiles, revegetation materials) and sedimentation (e.g., silt fences) control devices is to be provided on site to control erosion and sedimentation and respond to unexpected events.

• The size of the disturbed areas at the construction site is to be minimized. The extent of the work area is to be demarcated on the site to ensure that the Contractor does not work beyond these bounds.

• Phase construction to minimize the time that soils are exposed.

• Revegetate/stabilize slopes as soon as possible after exposure.

• Erosion and sedimentation control measures (e.g., silt fence barriers, flow dissipaters, rock flow check dams, etc.) will be installed and maintained as required in accordance with OPSS.

• Sediment control measures will be used during any dewatering of open excavations, should they be required.

• Stockpiles will have appropriate barrier/covers to prevent wind and water erosion, as necessary.

With the implementation of the proposed mitigation measures as outlined above, it is anticipated that soil erosion on the construction site will be minor, temporary and localized.

4.2 Groundwater Rehabilitation of significant areas of soil compaction following construction (as discussed in Section 3.2) will ensure that soil compaction around the site is limited with no significant adverse effects on water infiltration, and hence groundwater recharge, is anticipated to occur.

Section 4.13 details the mitigation to prevent or minimize the potential adverse effects of accidental spills during construction.

4.3 Surface Water Quality Some minor increase in the rate and/or volume of runoff may occur from the removal of vegetation, soil compaction and the addition of impervious surfaces associated with construction and installation of the Project. As a means to manage the potential effects of site



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-3


alteration on surface water runoff conditions during the construction phase, the following mitigation measures are provided

• Existing drainage patterns on the site will be maintained to the extent possible and/or as required to maintain the common law drainage rights of upstream or downstream riparian landowners.

• New drainage swales or channels will be constructed as grassed swales to provide extended flow times, filtering of runoff and reduce the potential for erosion.

• Rainfall runoff from the solar modules, parking lots and access roads will be directed to grassed and vegetated areas, which will allow for infiltration into the soil and filtering of runoff by vegetation prior to its conveyance to receiving watercourses.

• All identified water body features will be protected and no solar modules will be installed within 120 m from a water body.

Mitigation measures identified with respect to other resources will be effective at preventing impacts to surface water quality

• mitigation for contamination from accidental spills (see Section 4.13)

• mitigation for erosion/sedimentation is addressed in soils (see Section 4.1)

• mitigation for fugitive dust deposition is addressed in air quality (see Section 4.7).

As a result of the use of effective mitigation measures, it is anticipated that there will be no resulting adverse effect on surface water quality.

4.4 Aquatic Habitat/Biota Aquatic biota (e.g., fish and benthic invertebrates) and their habitat will not be directly affected by solar module, inverter and transformer installation, since none of these will occur within 30 m of the average annual high water mark of the watercourse.

4.4.1 Indirect Effects Aquatic biota and habitat could potentially be indirectly affected if changes in surface water runoff, surface water quality and groundwater quality or quantity were to occur as a result of the construction phase of the Project. However, the mitigation previously proposed is anticipated to be effective in preventing/minimizing negative effects associated with these other biophysical components of the environment, such that there are no adverse effects on aquatic biota and habitat within the tributary on and adjacent to the site. Given this, no specific mitigation measures, other than those noted in the above-mentioned sections, are required to prevent adverse effects to aquatic biota and habitat.



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-4


4.5 Vegetation As was identified in Section 3.6, vegetation communities may be impacted by clearing of the hedgerow, accidental spills or movement of dust off site. Mitigation measures with respect to potential impacts of accidental spills on vegetation communities are addressed in Section 4.13. In addition, mitigation measures with respect to the movement of dust from the Project Location are described in Section 4.7. As a result of the effective use of the mitigation measures identified in these sections, potential impacts to vegetation communities from these impacts are expected to be fully mitigated and there is no resulting effect.

It is not possible to mitigate the impacts of clearing from the hedgerow. In order to minimize potential losses from surrounding vegetation communities, areas where clearing is required will be well marked and workers will be instructed not to enter areas of natural vegetation. In addition, cleared and grubbed materials will be piled away from the surrounding woodlands, and trees will be felled into cleared areas.

4.6 Wildlife As described in Section 3.7, wildlife populations are not likely to be impacted by loss of habitat, disturbance due to construction activities and incidental take.

To further minimize the potential for habitat loss, work areas will be demarcated in order to ensure that the Contractor does not work beyond those bounds.

Once the fence is completed, a visual search of the Project Location will be conducted to search for any trapped wildlife species. If species are observed, they will be directed off of the Project site.

At any point in time during construction, if wildlife are observed in a work area, they will be directed off of the Project Location by the worker (without the use of vehicles).

In order to minimize potential for disturbance or incidental take of wildlife, site preparation will be timed outside of the breeding bird period (generally May through July), wherever possible. If this is not possible, a trained avian biologist will inspect the proposed work area, plus an additional 100 m around the area, for nesting birds prior to any work being done to delineate workable areas (i.e., avoiding nests or other sensitive breeding habitat until area is abandoned for wildlife breeding). If an active nest of a species covered under the federal Migratory Birds Convention Act (MBCA) or the provincial Fish and Wildlife Conservation Act (FWCA) is located within a proposed work area, a mitigation plan (which may include the establishment of buffers around the active nests) will be developed to prevent impacts on birds or their active nests and submitted to Environment Canada (EC) (for MBCA species) or Ontario MNRF (for FWCA species) for review prior to implementation.

In spite of the mitigation measures identified above, it is anticipated that there will be some disturbance of wildlife populations on and in the vicinity of the Project Location during



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-5


construction, however, these effects are minor, temporary, and reversible. In addition, it is possible that there may be an incidental take of a species of wildlife during the construction; however, species observed on the Project Location are common to the regional area and loss of one or a few individuals will have a negligible effect on population size at the local and regional levels. In order to minimize the potential for incidental take of wildlife, speeds on access roads of the Project Location will be restricted. Further, the construction workforce will be made aware of the potential for wildlife occurring on the Project Location, and the characteristics and behaviour of species of conservation concern will be identified to the workforce to make them aware of their potential presence. The construction workforce will be advised that measures should be taken to avoid wildlife wherever possible.

4.7 Air Quality and Noise The use of standard construction best management practices and mitigation measures, such as those identified in “Best Practices for the Reduction of Air Emissions from Construction and Demolition Activities” (Cheminfo Services Inc., 2005), will be used. These mitigation measures are to include, as required

• use of dust suppression (i.e., water) on exposed areas including access roads, stockpiles and work/lay-down areas as necessary

• hard surfacing (addition of coarse rock) of access roads or other high-traffic work areas

• avoid earth-moving works during excessively windy weather

• stockpiles and other disturbed areas to be stabilized as necessary (e.g., taped, mulched, graded, revegetated or watered to create a hard surface crust) to reduce/prevent erosion and escape of fugitive dust

• dust curtain to be used on loaded dump trucks delivering materials from off site

• workers to utilize appropriate personal protective equipment (e.g., masks, safety goggles) as necessary.

The use of these mitigation measures would be expected to mitigate most effects of dust on local air quality with any impacts expected to be temporary in nature.

Construction and installation activities that produce a large amount of noise will be limited to daylight hours. Vehicles will also be regularly checked for properly working mufflers or other noise reducing equipment, and all construction equipment will meet MOECC emission standards (NPC 115). Construction activities will comply with the local noise control by-law. In spite of the mitigation measures identified above, it is anticipated that noise from the Project will have some effect on local wildlife populations (addressed in Section 4.6, above) and nearby sensitive receptors. In order to minimize impacts on sensitive receptors, receptors will be made aware of a contact person for complaints relating to noise during the Project



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-6


construction. As construction will last for approximately 3 to 6 months, the resulting effect on nearby receptors is expected to be minor, temporary and reversible.

4.8 Traffic Potential negative effects as a result of increased traffic volumes and equipment delivery to the Project Location as well as temporary disruption along routes utilized by construction vehicles can be minimized with the implementation of the following proposed mitigation measures

• designated transportation routes will be utilized

• a police or security escort will be utilized to guide or accompany major equipment deliveries to the Project Location, if necessary

• flagmen will be utilized as required to facilitate traffic flow and control, if necessary

• construction vehicles will be driven in a proper manner with respect for all traffic laws

• signage providing any detour directions will be prominently displayed

• vehicle imprints or erosion gullies will be repaired or regraded as necessary.

As a result, impacts to traffic will be minor, temporary and reversible following Project construction.

4.9 Municipal Roadways Damage to municipal roadways caused by construction vehicle traffic may occur during the construction of the Project. The following mitigation measures are proposed to minimize this potential negative effect

• designated transportation routes will be established for heavy construction vehicles and equipment deliveries to the site

• construction vehicles will be driven in a proper manner with respect for all traffic laws

• any municipal requirements for half-load restrictions on identified roads will be adhered to

• damage to municipal roadways will be repaired by the Contractor as necessary during the construction period.

There will be no residual effect to municipal roadways following the use of these mitigation measures.

4.10 Public and Construction Site Safety in the Vicinity of the Project Implementation of the following mitigation measures will serve to minimize potential risk to public and construction staff safety within the Project Location



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-7


• public access to the construction area will be prevented through the use of fences, gates, or other security procedures

• signage will be posted to notify the public of construction in the area

• workers will be required to adhere to prescribed safety procedures

• proper procedures for construction traffic will be developed, where required.

As a result, the risk to public and construction site safety is effectively minimized following the use of these mitigation measures.

4.11 Waste Management Solid wastes generated during construction will include construction waste such as material packaging and scrap material as well as domestic waste such as food and sanitary waste. Sanitary facility on site will include portable self-contained toilets and washroom facility. The following mitigation measures will serve to minimize any potential negative effects as a result of the generation of waste and recyclables

• construction waste will be properly stored on site prior to disposal off site at local, registered disposal facility

• all sanitary waste is to be contained and hauled off site by a designated hauler throughout the construction period

• hazardous wastes will be properly stored in secure containers inside impervious berms or other containment areas until disposal off site at a registered facility

• reuse and recycling will be practiced wherever possible.

The use of these mitigation measures will minimize any environmental effects resulting from the generation of waste.

4.12 Archaeological Resources Following the Stage 1 Archaeological Assessment, there remains a potential to uncover deeply buried archaeological resources (including human burial sites) during construction of the Project, which would not have previously been identified. In this instance, the MTCS has specified mitigation that must be undertaken in the event of discovery of human remains or other archaeologically or culturally significant material

• should human remains or artifacts be identified during construction, all work in the vicinity of the discovery is to be halted immediately, as required under the Ontario Heritage Act

• if human remains are found, notification is to be made to the Ontario Provincial Police (OPP), or local police who will conduct a site investigation and contact the district coroner



Report

H353010-00000-121-066-0068, Rev. 0, Page 4-8


• notification is to be made to the Development Plans Review Office of the Ontario Ministry of Tourism and Culture, Heritage Libraries Branch, Heritage Operations Unit, 400 University Ave, 4th Floor, Toronto, ON, M7A 2R9, and Registrar of Cemeteries, Ontario Ministry of Consumer and Commercial Relations

• work is to be halted in the immediate area where artifacts are found. Work will resume once the site has been investigated and cleared by a licensed archaeologist.

The mitigation measures identified above will effectively minimize impacts on archaeological resources within the Project Location.

4.13 Spills Accidental spills have the potential to occur during construction and, accordingly, appropriate safeguards will be put in place to prevent contamination of the terrestrial or aquatic environments. Contaminants that will be used during construction and have the potential to be spilled consist of PHCs (from fuel storage and transport, vehicle maintenance and in transformers), concrete materials (from concrete trucks), sewage (from portable toilets), and silt (from clearing and earth-moving operations).

To mitigate the potential for spills during construction, the Contractor will be responsible for ensuring that the Project is constructed using environmental best management practices. The following measures will be implemented

• A designated Site Environmental Inspector will be appointed by the Contractor. This person will be responsible for ensuring that the Contractor(s) have prepared a spill clean-up procedure/emergency response plan and appropriate equipment, with all staff trained in proper implementation in the event of a spill.

• Emergency Contacts including 911, Police, Fire Department, MOE Spills Action Centre will be posted and contacted as required.

• All potentially hazardous materials, fuels and lubricants must be stored in the lay-down area, in a protected/bermed area and at least 30 m from watercourses.

• All refuelling and equipment maintenance activities will be conducted off-site.

• Equipment is to be monitored to ensure it is well maintained and free of leaks.

• Spill containment and cleanup supplies are to be maintained on site at all times.

• Spill will be cleaned up immediately and reported accordingly.

• Portable toilets will be located no closer than 50 m from a watercourse/drain and will be pumped by an MOECC approved hauler to an approved facility.

• A sediment and erosion control plan will be developed and implemented.

• Erosion and sediment control systems must be installed in any location where erosion or sediment could discharge directly into a surface watercourse. An adequate supply of erosion and sediment control devices (e.g., silt fences) will be maintained on site during construction.

• The size of cleared and disturbed area is to be minimized where possible.

• Excavated, erodible material is to be placed in suitable designated areas away from watercourses and stabilized with erosion protection.

As a result, the effective use of mitigation measures will prevent impacts on soils, groundwater, surface water, vegetation and terrestrial or aquatic biota.

4.14 Contaminated Surficial Soils Disturbance of contaminated surficial soils has the potential to occur during construction and, accordingly, appropriate safeguards will be put in place to prevent the occurrence of adverse effects. To mitigate the potential for adverse effects as a result of ground disturbance activities, the Contractor will be responsible for ensuring that the Project is constructed using environmental best management practices. The following measures will be implemented

• A health and safety plan will be developed by the Contractor prior to initiating the field activities. This plan will include policies and procedures to protect workers and the public from potential hazards posed by site activities.

• Emergency Contacts including 911, Police, Fire Department, MOECC Spills Action Centre will be posted and contacted as required.

• A sediment and erosion control plan will be developed and implemented.

• Erosion and sediment control systems must be installed in any location where erosion or sediment could discharge directly into a surface watercourse. An adequate supply of erosion and sediment control devices (e.g., silt fences) will be maintained on site during construction.

• The size of cleared and disturbed area is to be minimized where possible.

• Excavated soil is will be managed to prevent sediment accumulation in stormwater runoff.

• Excavated, erodible material is to be placed on-site, in suitable designated areas away from watercourses and stabilized with erosion protection.

5. Environmental Effects Monitoring Plan Table 5-1 provides a summary of the potential negative environmental effects and proposed mitigation measures to prevent or minimize effects such that they are not significant. Based on the assessment findings of potential effects conducted as part of this Construction Plan Report and implementation of the recommended mitigation measures, no significant residual negative effects are expected as a result of construction of the Project.

As previously noted, several other Project reports have documented potential negative environmental effects and mitigation measures. Those persons seeking additional information on specific environmental resource features are referred to in these reports. These reports and the context of the potential negative environmental effects are as follows:

• Project Description Report, which summarizes potential negative environmental effects for features within 300 m of the Project for construction, operation and decommissioning phases.

• Construction Plan Report, which identifies potential negative environmental effects caused by construction and installation of the Project for features within 300 m of the Project.

• Design and Operations Report, which identifies potential negative environmental effects caused by the operation of the Project for features within 300 m of the Project.

• Decommissioning Plan Report, which identifies potential negative environmental effects caused by decommissioning the Project.

• Noise Study Report, which identifies potential negative environmental effects (noise emissions) caused by the Project’s electrical transformers and inverters during operation, as well as proposed mitigation measures.

• Archaeological Assessment, which identifies potential negative effects to archaeological resources from construction activities.

• Natural Heritage Assessment Report, which identifies potential negative effects to significant natural heritage features within 120 m of the Project for construction, operation and decommissioning phases.

• Water Assessment Report, which identifies potential negative effects to waterbodies within 120m of the Project for construction, operation and decommissioning phases.

5.1 Monitoring Plan Table 5-2 presents the environmental effects monitoring plan for the Project construction, which includes the following information



Report

H353010-00000-121-066-0068, Rev. 0, Page 5-2


• the potential negative environmental effects, carried forward from Table 5-1, that have an ongoing risk of occurrence throughout the construction period

• the performance objectives and mitigation strategies to address those effects

• monitoring protocols to confirm that performance objectives are being met

• contingency measures in the event that objectives are not met, i.e., if monitoring reveals that negative effects are continuing to occur.

Mitigation measures identified in Table 5-2 are expected to either completely mitigate or reduce the scale of potential effects to such a minor level that quantifiable detection of residual effect(s) through specialized field measurements, sampling or laboratory analyses are not considered possible or necessary. Therefore, the recommended monitoring methods are based solely on qualitative, visual inspections and reporting methods to ensure compliance with the performance objectives identified for the respective mitigation measures.

Monitoring will typically consist of weekly inspections of the Project Location during construction and installation activities by the Contractor (or an inspector retained by the Contractor) with reporting responsibilities directly to the Proponent. The inspector will ensure that all mitigation measures (e.g., sediment and erosion controls) described in this report are in place and functioning according to design specifications. If required, repairs will be made to mitigation measures and, if necessary, remedial action such as implementing additional mitigation measures will be undertaken.

Table 5-1: Summary of Potential Negative Environmental Effects and Proposed Mitigation – Construction Phase

Environmental Component Sources of Negative Effect Potential Negative Effect Mitigation Measures Residual Negative Effect

Natural Environment Components Soils Wind and water erosion from exposed surfaces

following vegetation removal and minor grading activities.

Loss of soils from the Project Location, potentially affecting other environmental components (e.g., air quality, vegetation, surface water quality).

Sediment and erosion controls (e.g., silt fence barriers, rock flow check dams) installed and maintained during construction. Dense non-invasive vegetation ground cover planted throughout disturbed areas of the Project Location following construction.

Some minor soil erosion on-site within the Project Location may be unavoidable due to runoff from exposed soils during heavy rainfalls events or extremely windy days.

Groundwater Dewatering of excavations for foundations for inverter/transformers and trenching for electrical cabling to keep the work area dry.

No adverse effect on water table or nearby water wells since significant pumping of groundwater is not required. Some pumping of rainwater out of excavations may occur.

If pumping is required, water will be discharged to a heavily vegetated area or pumped through a filtration bag so that turbid water is not discharged directly to receiving watercourses.

No residual effect given effective mitigation.

Surface Water Alteration of existing topography and surface drainage patterns from earth grading and excavation activities. Runoff from impervious and less pervious areas (e.g., gravel roads). Installation of new drainage swales, ditches and culverts.

Minor increase in surface water runoff from Project Location to off-site receiving drainage swales, ditches and/or watercourses resulting in erosion. Potential adverse effects to receiving water quality due to increased turbidity in runoff due to soil erosion.

Maintain existing drainage patterns as much as possible. Retain and/or plant dense vegetation as soon as possible following construction. Sediment and erosion controls installed and maintained during construction. Stormwater management measures installed to control increases in runoff peak flows from the Project Location to pre-construction condition levels.

Minor potential for residual effects until disturbed areas become completely stabilized by vegetative cover and plant growth. No residual post-construction effects.

Wind and/or water erosion of soils within the Project Location.

Erosion of soils from the Project Location could result in adverse effects on surface water quality in receiving waterbodies, with associated effects on aquatic biota and habitat.

Sediment and erosion controls installed and maintained during construction.


Aquatic Habitat and Biota

Erosion, increases in surface water runoff, accidental spills on Project Location.

Indirect effects to aquatic habitat and biota in receiving watercourses due to increased turbidity in runoff, sedimentation or accidental spills.

Mitigation measures for Soils, Surface Water and Spills will mitigate any potential adverse impacts to aquatic features located on or off site.


Vegetation Clearing of woodlands and hedgerows within the Project Location.

No adverse impacts since vegetation is non-significant. Some minor potential for damage to adjacent trees/shrubs and/or disturbance to the rooting zone through soil compaction. Increased surface water and soil erosion, and potential indirect effects to receiving water quality due to vegetation removal.

Work areas will be demarcated in order to ensure that the Contractor does not work beyond those bounds. Soil loosening methods for compacted soils. Dense non-invasive vegetation ground cover planted throughout disturbed areas of the Project Location. Mitigation measures for: Soils and Surface Water will minimize potential for increased runoff and erosion.


Generation of airborne dust from construction activities.

Indirect effects to adjacent off-site significant woodlands north and east of Project Location could include deposition of dust on leaves.

Mitigation measures for: Air Quality and Soils will minimize generation of airborne dust to adjacent off-site vegetation communities.

Minor potential for residual effect associated with generation of airborne dust from exposed soils during construction activities that occur on extremely windy days.

Wildlife Habitat Clearing of woodlands and hedgerows within the Project Location.

Some minor loss of non-significant wildlife habitat associated with woodlands and hedgerows.

Vegetation removal will be conducted outside the breeding period for birds (May through July). Work areas will be demarcated in order to ensure that the Contractor does not work beyond those bounds. Sediment and erosion controls and stormwater management mitigation measures implemented during construction will prevent adverse effects off-site effects to wildlife habitats.

Long-term wildlife use of the Project Location will be altered, but no overall change in local composition or population is anticipated to occur.

Wildlife Construction activities and presence of workforce. Avoidance of Project Location by wildlife due to equipment, noise and human presence. Possible noise disturbance to breeding birds in woodlands adjacent to the Project Location.

Site preparation will be timed to occur outside of the bird breeding period wherever possible.

Minor periodic disturbance of local wildlife during construction. Sufficient retreat habitat is available in the local area such that impact is anticipated to be negligible.

Construction activities and vehicles travelling on access roads within Project Location.

Incidental take of wildlife due to construction activities and vehicles within Project Location.

To reduce incidental take of nesting birds, vegetative clearing, excavation or grading will be timed outside of the breeding bird period (May through July). If this is not possible, the area(s) potentially impacted will be searched by a trained biologist within 48 hours of the proposed activity to determine if birds are nesting. Daily visual monitoring of construction work areas prior to start or work. Limit on-site vehicles speed to avoid incidental take.

Mitigation will effectively reduce risk of incidental take of wildlife, but not completely eliminate it. No long-term effects on species composition or local populations anticipated.


H353010-00000-121-066-0068, Rev. 0, Page 5-4



Installation of perimeter fencing around the Project Location (excluding Connection Line location).

Trapping of wildlife within the Project fence. Prior to fence completion, a visual search of the area within the fence will be completed. If species are observed, they will be directed off the Project site.

No long term residual effect on wildlife.

Socio-Economic Environmental Components Air Quality Generation of airborne dust from construction

activities, vehicle travel on dirt roads and exhaust emissions from construction vehicles and equipment.

Reductions in local air quality from airborne dust and exhaust emissions from construction vehicles and equipment.

Construction practices to suppress dust (e.g., limit soil exposure, road watering, stabilize and cover stockpiles) and restrict soil working activities during windy conditions. Contractor to ensure that all construction vehicles and equipment have properly functioning emission controls (e.g., mufflers and no excessive vehicle idling).

Some short term minor effects on local air quality due to fugitive dust generation and vehicle emissions.

Noise Noise emissions from construction vehicles and equipment use.

Disturbances to nearby sensitive receptors (i.e., houses and institutions) due to noise emissions.

Contractor to comply with municipal Noise Control By-Laws for construction working times and ensure that vehicles and equipment have proper sound baffling equipment (e.g., mufflers). Notification to adjacent noise receptors to report noise complaints.

Possibly, some short-term, temporary ‘nuisance’ disturbance to sensitive nearby noise receptors during certain construction activities.

Traffic Construction vehicles and workforce commuters travelling to and from the Project.

Increased traffic volumes and equipment delivery to the Project Location and temporary disruption along routes utilized by construction vehicles may result in occasional delays to local community traffic flow during the construction period.

Prepare transportation route plan and delivery scheduling to avoid potential bottlenecks of equipment deliveries to site. Construction flag-person to direct vehicles into and out of the site.

None.

Municipal Roadways

Construction vehicles travelling to and from the Project.

Heavy construction vehicles may damage local roadways. Municipal ‘half-load’ requirements for roads will be adhered to. Any damage to local roadways will be repaired by the Contractor.


Public and Construction Site Safety

Construction equipment malfunction, fire or accidents resulting in injury to public or construction workers.

Personal injury to the public if trespassing on-site or to construction workers due to accidents, fire or equipment malfunction.

Public access to construction site will be prevented by fences, gates and security procedures. Proper health and safety procedures for construction workers will be implemented as per provincial and federal regulations.

No risk to public safety unless trespassers obtain access to the site. Health and safety procedures will reduce risk of personal injury to workers, but some risk from accidents will remain during construction.

Protected Properties, Built Heritages and Cultural Heritage Landscapes

Construction and installation of Project facility resulting in the loss (e.g., demolition of existing built structures) and/or alteration to significant cultural heritage features or landscapes.

No protected properties, as defined in Section 19(1) of O. Reg. 359/09, exist in the vicinity of the Project Location. No negative effects to built heritage and cultural heritage landscapes since such features were either not present in the Project Location or potential effects (if any) were assessed as not significant.

None required. None.

Archaeological Resources

Trenching for underground electrical cables. Following the Stage 1 Archaeological Assessment there remains a potential to uncover deeply buried heritage or archaeological resources (including human burial sites) which would not have previously been identified.

If construction results in discovery of human remains or archaeological resources, work is to be halted immediately and MTCS notified.

None. Mitigation will be effective in preventing residual negative effects to human remains or archaeological resources if discovered during construction.

Waste Management

Construction activities will likely result in the generation of recyclable material, as well as construction and sanitary waste.

Generation of waste material will occur within the Project location, and wastes and recyclables will be transported to the nearest approved facility for disposal or recycling.

Construction waste will be properly stored on site prior to disposal off site at local, registered disposal facility; all sanitary waste is to be contained and hauled off site by a designated hauler throughout the construction period; hazardous wastes will be properly stored in secure containers inside impervious berms or other containment areas until disposal off site at a registered facility; reuse and recycling will be practiced wherever possible.

None.

Effects Due to Accidental Spills Groundwater, Surface Water, Soils, Vegetation, Aquatic Habitat

Accidental spills or leakage of fuel, oil, hydraulic fluid, etc., from construction vehicles or equipment, on-site refuelling or storage of toxic liquids on-site.

Impairment of groundwater, soil and/or surface water quality due to contamination. Potential adverse effects to vegetation and aquatic habitats.

Visual monitoring and reporting procedures to identify spills. Spill control kits on-site and spill response procedures implemented in the event of an accidental spill. Contractor’s staff will be trained in spill response procedures. No refuelling or storage of toxic liquids on-site within 30 m of a watercourse.

No residual effect given effective mitigation (e.g., proper storage and handling of toxic liquids) and spill response and clean-up measures if a spill occurs.


H353010-00000-121-066-0068, Rev. 0, Page 5-5



Effects Due to the Presence of Contaminated Surficial Soils Soils, Surface Water, Groundwater

Wind and water erosion from exposed surfaces and ground disturbance following vegetation removal and minor grading activities as well as trenching for underground electrical cables.

Risks to health and safety of workers as well as members of the public; contamination of soils, surface water, and groundwater with materials inhospitable to the promotion of biological life; uptake/ingestion by, or coating of, vegetation species or terrestrial and aquatic biota resulting in senescence or individual mortality.

A health and safety plan will be developed by the Contractor prior to initiating the field activities; a sediment and erosion control plan will be developed and implemented; Erosion and sediment control systems must be installed; An adequate supply of erosion and sediment control devices (e.g., silt fences) will be maintained on site during construction; The size of cleared and disturbed area is to be minimized where possible; Excavated soil will be managed to prevent sediment accumulation in stormwater runoff; Excavated, erodible material is to be placed on-site, in suitable designated areas away from watercourses and stabilized with erosion protection excavated trenches backfilled with on-site soils adjacent to existing ditches should be supplied with a suitable cutoff collar in the trench (e.g., bentonite) to prevent offsite migration of potential contaminants.
