5 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 1. Introduction 1.1 OVERVIEW Saturn Power Inc. ( Saturn ) is proposing to develop, construct and operate the 1 Megawatt (MW) avid Brown Solar Park ( the Project ) within the Township of South Stormont, United Counties of Stormont, undas and Glengarry, Ontario, in response to the Government of Ontario s initiative to promote the development of renewable electricity in the province. For the purposes of this report, the Project Location represents the proposed physical footprint of the Project including the proposed facility components and temporary areas used during construction. The Zone of Investigation includes the Project Location in addition to a 12 metre (m) radius around the Project Location used to conduct environmental investigations.

No surface water takings are required for the Project. No sewage works are required for the Project. Based on the anticipated lack of changes to hydrology, no detention or treatment of stormwater is expected to be required. A passive system of ditches/swales alongside access roads and within the site will be designed following a stormwater management plan conducted as part of the detailed design by the EPC contractor. Sources of localized emissions during operation are considered negligible under O. Reg. 419/5. The Project has no facilities or equipment that will discharge contaminants or pollutants to the air (e.g., exhaust gases from emergency backup diesel generators) during operation of the Project. Minor emissions would occur from maintenance staff vehicles (e.g., service trucks or panel washing spray trucks). No waste management equipment, facilities, or equipment is required for the Project. A small waste bin will be located near the substation. Larger waste will be transported off-site for proper disposal. Buildings are shown on the aerial imagery shown on all Site Plan maps; these are primarily residences located on the north side of Highway 41 and industrial facilities south along ickinson Road. Public roads are shown on all Site Plan maps. Highway 41 is adjacent to the north side of the Project, ickinson Road is adjacent to the east side of the Project. afoe St and Railway Road are within 3 m of the Project. A railway owned by Canadian National Railway is adjacent t to the south side of the Project. The railway property is shown on all Site Plan maps. TransCanada owns a pipeline within 3m of the Project, as shown on the Site Plan maps.. An existing distribution lined owned and operated by Hydro One transects the Project Location. An agreement has been reached between Saturn Power and Hydro One to relocate the distribution line off of the subject property prior to construction. Wells as mapped by the MOE well water records (211) are shown on Figure 3. There are no petroleum wells within 3m of the Project Location. Topographical land contours Land contours are shown on Figures 2 and 3.

Inverter stations including the inverter and transformers are shown on all Site Plan maps. istances to closest noise receptors: Station 1 (183 m); Station 2 (186 m); Station 3 (197 m); Station 4 (239 m); Station 5 (292 m); Station 6 (317 m); Station 7 (316 m); Station 8 (313 m); Station 9 (311 m); Station 1 (273 m). The outer limit of all Project components, including temporary work areas during construction, is shown as the Project Location on all Site Plan maps. None identified within 3 m of the Project Location. No built heritage resources (BHR) were identified within 3 m of the Project Location. Archaeological assessment did not identify any archaeological sites within the Project Location. A minor private drain transects the north end of the Project. An existing road crossing and culvert across this drain will be used as part of the Project. Fencing and access roads cross the drain at the existing culvert and are generally within 5 metres of the drain in other locations. The inverter station, transformer substation and solar panels are a minimum 3 metres from the drain. Temporary construction laydown area is within 1m of the drain. Potential constructible area is 3m from the drain. The natural heritage assessment identified two natural features treated as significant within 12 m of the Project Location. Within these features are three wetlands and wildlife habitat in the form of amphibian woodland breeding ponds and woodland area-sensitive breeding bird habitat. Feature 2 is adjacent to the west end of the Project Location with a small portion of the feature located in the Project Location. The overlap between the Project Location and Feature 2 is only in woodland not wetland. Feature 3 is located outside of the Project Location south of the subject property on the opposite side of the active railway corridor and is located 11.4 m from the Project Location. 2.3

13 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 3. Facility esign Plan This section provides a description of the design of the key facility components identified on the Site Plan (Appendix A). 3.1 GENERAL ESIGN AN SITING CONSIERATIONS The key mitigation strategy used to address potential environmental effects from construction and operation of the facility was avoidance of significant natural and socio-economic features to the extent possible during siting of the Project. The original Project Location proposed in the early stage of the REA process included the entire 14 acre property. Upon completion of the Natural Heritage Assessment, the original Project Location was determined to include a portion of large unevaluated wetland in close proximity to the Provincially Significant Ingleside Swamp. The Project Location was revised to maintain a setback of 4 m from the boundary of this unevaluated wetland. Upon consultation with neighbouring property owners it was determined that the Ontario Ministry of Transportation (MTO) would not permit the construction of any permanent structures (fences, pole lines, foundations, buildings, etc.) within a certain distance from the shared property line of the Highway 41 and within the intersection of ickinson Road and Highway 41. The MTO has long term expansion plans for the exit off the Highway 47 and the boundaries of this potential expansion were considered by siting all permanent structures setback from the northeast corner of the property (where the temporary construction laydown area is located). Figure 3 demonstrates the boundary of the UHL. An existing culvert with a gravel access road crosses the existing drain and provides access to the main portion of the property. The design considered the use of this crossing and avoided introducing new or additional water crossings. Potential effects and mitigation measures associated with Project operations are discussed in Section FACILITY COMPONENTS OVERVIEW The Project is being designed and constructed to generate 1 MW of power. The basic Project components include up to 55, solar PV panels, pole-mounted on to approximately 5, solar arrays on fixed, ground-mounted racking structures, direct current cabling and combiner boxes, electrical inverter stations (with medium voltage transformers), collector system, interconnection station, communication tower, distribution line, access roads, temporary staging areas and perimeter fencing. Please refer to the Project escription Report for a detailed description of the facility components. Equipment specifications including dimensions are included in Appendix B. 3.1

14 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Facility esign Plan February 213 No equipment in the facility design relate to groundwater and surface water supplies, air discharges and/or water and biomass management Key Process Features Waste Management No waste management equipment, facilities, or equipment is required during Project operation. A small waste bin(s) will be located near the interconnection station to collect small amounts of domestic waste and debris resulting from maintenance activities (e.g. broken equipment parts and packaging). A licensed waste disposal company will be hired to periodically empty the bins. Any large waste generated during operation will be hauled off-site for disposal at an accredited waste disposal facility. Small amounts of waste lubricants and oils may be generated during regular maintenance activities of the equipment throughout the operation phase. A licensed contractor will be charged with their disposal at an approved facility when the need arises. Air, ust and Emissions Minor, localized air emissions would occur during operation from the periodic use of maintenance staff vehicles and equipment. The Project has no facilities or equipment that will discharge contaminants or pollutants to the air (e.g., exhaust gases from emergency backup diesel generators) during operation of the Project. Sources of localized emissions during operation are considered negligible under O. Reg. 419/5. Noise Emissions uring the operation phase, the sound contribution from the units is expected to be minimal at the nearby receptors. Sources of sound may include the transformers and inverters. Noise levels from the equipment are assessed and documented in the Noise Study Report included with the REA package. The assessment confirms that the Project is in compliance with the applicable MOE environmental noise guidelines at all receptors. Periodic activities such as panel washing and general repair and maintenance measures may also cause minimal noise Sewage and Stormwater Management uring operation, permanent on-site sanitary facilities are not required. If sanitary facilities are determined to be required, portable toilets and wash stations will be provided by a local sanitation company. As the solar panels are mounted above the ground, infiltration, filtration through vegetation, and other natural hydrologic processes will continue similar to existing conditions. Surface water 3.2

15 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Facility esign Plan February 213 from rainfall and snow will infiltrate through the existing permeable ground surface. Excess sheet flow from significant rainfall events will flow to a passive system of ditches/swales alongside roads and within the site. Based on the anticipated lack of changes to hydrology, no detention or treatment of stormwater is expected to be required. A site grading/stormwater management plan, completed prior to construction as part of the detailed design by the EPC or GC contractor, will illustrate how drainage boundaries are maintained and will ensure postdevelopment flows to the adjacent wetland will be similar to pre-development flows. Water-taking uring operation, no water taking activities are expected to be required. Water may be required during maintenance for cleaning of the solar panels, however, a temporary water storage facility would be used by a third party contractor to support panel cleaning. 3.3

16 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 4. Facility Operations Plan Operation activities include continuous remote monitoring of the solar farm and maintenance and inspection activities. 4.1 SITE SUPERVISION AN STAFF TRAINING The Project will have an Operations Manager, who will be responsible for the day-to-day management of all Project facilities, including supervising site activities, site inspections, facility maintenance and repair. Saturn Power will confirm that the Operations Manager ensures compliance with all applicable municipal, provincial, and/or federal requirements. Responsibilities would include staff training, health and safety training and compliance, predictive/preventive maintenance, routine maintenance, unscheduled maintenance (including appropriate environmental mitigation measures), annual overhauling, inspection of equipment and components, and procurement of spare parts. It would also include a schedule for regular inspections of the Project s facilities. It is expected that approximately two part-time or full-time staff would be employed by the Project to conduct general monitoring and maintenance activities. Some maintenance activities may require temporary use of qualified professional contractors. 4.2 REMOTE MONITORING The Project will be operated and monitored remotely from Saturn Power main office or alternative and therefore no employees will be on site other than to conduct maintenance and inspection activities. The remote monitoring would occur 24 hours a day/7 days a week via a supervisory control and data acquisition (SCAA) monitoring system connected to the data cabling installed in conjunction with the electrical collector system throughout the site. The operation staff would be able to monitor the performance of the PV modules and electrical systems in a real time basis from a remote location. The SCAA system would identify any potential damage or faults with the PV modules and electrical infrastructure so that proactive inspection and maintenance could be undertaken. 4.3 PLANNE MAINTENANCE Regular maintenance of Project equipment would be a key method of mitigating potential effects such as equipment failure. Preventative maintenance activities would generally occur every two to three months and would include inspection of the solar panels, interconnections, inverters, and transformers. 4.1

17 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Facility Operations Plan February 213 If an accumulation of dust reduces the efficiency of the panels, they would be pressure-sprayed with water. No cleaning solutions are anticipated to be used. The water used for cleaning the panels will be trucked in from an off-site source. In the winter, the access roads would be ploughed. In terms of snow accumulation on the panels, it is expected that snow will melt or slide off due to the tilt of the modules, however it is possible that in some cases removal will be necessary. In that event, maintenance staff would manually remove the snow using brushes. The transformers will be routinely inspected, and spill response equipment will be left on site or in the maintenance trucks should leaks be observed. An oil/grease sensor would be mounted in the 1 MVA transformer oil containment pit at the interconnection station to detect any oil/grease leaking. If there is oil/grease detected, the liquid would be removed from site via a licensed waste hauler and the source of the leakage would be determined and rectified. The oil containment pit will be designed to hold all of the liquid from the transformer as well as any precipitation that may accumulate. A licensed contractor will be charged with emptying the small waste bin(s) at an approved facility as required. All required maintenance materials (e.g. hydraulic fluids) will be brought on-site by maintenance personnel; therefore no on-site storage of these materials will be necessary. The Operations Manager will implement a vegetation management plan (or equivalently, an Agricultural Plan/Soils Plan) related to the ground cover beneath the panels. While the species of vegetation to be established under the panels has not yet been selected, the ground cover beneath the panels should require only minimal maintenance and would assist in preventing the invasion of non-native grassland species. epending on the species selected, the vegetation management plan may include mowing of the site for aesthetic purposes and to ensure vegetation does not grow tall enough to shade the solar panels. A slow-growing vegetation would be used so that mowing could be infrequent. The vegetation management plan will define plans to minimize the quantities of herbicides intended to be used which will be significantly lower than an agricultural operation. Additionally, the vegetation management plan will include options for planting trees along the existing berm on the property, through consultation with the Mohawks of Akwesasne. Routine visual inspections of the Project site for any drainage, erosion or sedimentation issues will be conducted and remediation activities undertaken as required. This includes identification of areas of bare soil and/or the formation of erosive gullies, presence of trash/debris or excess density of vegetation within the passive stormwater conveyance system that would affect flows, and areas of isolated ponding. Remediation measures would include applying sod or seeding, re-grading, removal of trash/debris, and vegetation cutting as required. 4.2

18 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Facility Operations Plan February UNSCHEULE MAINTENANCE The Project will be inspected whenever the remote monitoring indicates a potential concern requiring a visit by personnel. For example, a reduction in power output may be indicative of a mechanical problem, or dust or snow accumulation. 4.3

19 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 5. Potential Environmental Effects and Mitigation Measures O. Reg. 359/9 requires that any adverse environmental effects that may result from operation and maintenance activities be described. Generally, an area within a 12 m radius of those activities has been considered in this assessment (known as the Zone of Investigation). The term environment in O. Reg. 359/9 includes the natural, physical, cultural, and socioeconomic environment. The sections below describe the potential effects, mitigation measures (if required) and net effects that may result from operation and maintenance activities. Mapping provided in Appendix A shows the Project Location and Study Area. A detailed description of the existing natural environment can be found within the Natural Heritage Assessment and Environmental Impact Study (NHA/EIS) and the Water Assessment and Water Body Report (WA/WBR). The detailed studies in these reports are completed in the context of a 12 m Zone of Investigation, also shown on mapping provided in Appendix A. A detailed description of the existing cultural heritage environment can be found within the Heritage Assessment (Protected Properties Report) and the Stage 1 & 2 Archaeological Assessment. In order to identify potential negative environmental affects that may result from operation of the Project, the following is a high level summary of the methodology that was applied: Collected information on the existing environment using available background information, consultation with stakeholders, and site investigations. Reviewed proposed Project activities in order to predict the potential interactions between the Project and environment. Identified potential interactions that could cause an adverse effect on the environment. eveloped measures to avoid, mitigate, and monitor potential adverse effects. The key mitigation strategy used to address potential environmental effects from operation of the facility was avoidance of natural and cultural heritage features to the extent possible during siting of the Project. Monitoring plans and contingency measures have also been outlined in order to ensure mitigation measures are functioning as intended. Where net effects remain, they are characterized as either positive or adverse. Adverse net effects were assessed using the following descriptors, as applicable: uration: the period of time until the element returns to baseline conditions; Frequency: the number of times that an effect may occur; Permanence: the degree to which an effect will not return to baseline conditions; 5.1

20 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Spatial Extent: the area within which an effect may occur. Positive net effects were not assessed further. The key performance objective for each of the features discussed below is avoiding and/or minimizing potential effects (through the use of appropriate mitigation measures) to the features throughout the operation phase of the Project. The proposed mitigation measures would assist in achieving this performance objective. Additional information related to specific performance objectives is detailed in the Environmental Effects Monitoring Plan provided in Section ARCHAEOLOGICAL AN CULTURAL HERITAGE RESOURCES The following sections describe the potential effects, recommended mitigation measures, and net effects for heritage and archaeological resources. In accordance with O. Reg. 359/9, a Stages 1 Archaeological Assessment, Stage 2 Archaeological Assessment and Heritage (Protected Properties) Assessment have been prepared for the Project (included under separate cover). The following provides a summary of the above mentioned reports Archaeological Resources The Stage 2 Archaeological Assessment of the Project Location identified no archaeological sites requiring further assessment and concluded that no further archaeological assessment of the property is required. Potential Effects There are no areas that would be excavated during the operation phase that would not have been previously assessed prior to construction; therefore no effects are anticipated to archaeological resources during operation. Mitigation Measures Given that there are no anticipated effects to known archaeological resources during operation of the Project, mitigation measures are not required. Net Effects No significant adverse net effects on archaeological resources are anticipated during operation of the Project. 5.2

21 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February Cultural Heritage Resources One resource of cultural heritage value, the CN Railway Line, is identified adjacent to the Project Location within the Study Area. No protected properties or cultural heritage landscapes are located within the Study Area. Potential Effects The Heritage Assessment concluded that there are no direct or indirect Project-related impacts on the CN Railway Line in terms of destruction, alteration, isolation, shadows, obstruction of views or change in land use. The Project is recommended to be released from further heritage requirements. Mitigation Measures Given that no direct or indirect Project-related impacts are identified on the CN Railway Line, mitigation measures are not required. Net Effects No negative impacts of significant magnitude have been identified to heritage resources or protected properties. 5.2 NATURAL HERITAGE RESOURCES In accordance with O. Reg. 359/9, an NHA/EIS was undertaken for the Project and is included under separate cover as part of the REA application. The following provides a summary of the potential effects and the associated mitigation measures as described in that report in relation to facility operation. In addition, potential effects and mitigation measures are identified for regulated features outside the setbacks, and unregulated natural features, which are therefore not considered in the NHA/EIS Significant Natural Features No significant wetlands were identified within the Project Location and therefore no direct loss of significant wetland is proposed as part of the Project. Two wetland features outside of the Project Location but within the 12m Zone of Investigation were treated as significant. The first wetland is 2.58 hectares and the second wetland is 62.2 hectares. The wetlands are also considered significant wildlife habitat for amphibian breeding. Two woodlands treated as significant were identified in and within 12m of the Project Location. The first woodland is 2.58 hectares made up primarily of sugar maple, green ash and some silver maple. The second woodland is 62.2 hectares made up primarily of Black Ash, Elm, Prickly Ash and Silver Maple. The woodlands are also considered significant wildlife habitat for amphibian breeding. 5.3

22 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 No other significant natural heritage features as defined by O. Reg. 359/9 are located within the Project Location or 12 m zone of investigation; it has been confirmed that no provincial parks or conservation reserves, provincially significant Areas of Natural and Scientific Interest, significant valleylands or significant woodlands occur within 12 m of the Project Location. Potential Effects Indirect impacts to woodland, flora species and vegetation communities are related to dust generation from maintenance traffic, sedimentation and erosion. uring operation of the facility, some materials such as lubricating oils and other fluids associated with solar panel and equipment maintenance have the potential for discharge to the on-site environment through accidental spills resulting in a potential impact to the natural features. Improper disposal of wastes (fluids, containers, cleaning materials) could also have a negative impact on the features. The proposed development plan has some ability to alter surface water inputs to the wetlands. Proposed roads and infrastructure can alter surface flow directions, and the increase in hard surfaces could result in increased run-off quantities during precipitation events. Site investigations did not identify any sensitive or specialized functions, including rare species associated with the wetlands. Potential indirect impacts to amphibian breeding areas including sensory disturbance, localized dust generation, soil erosion, sedimentation, chemical or fuel spills and direct mortality from traffic. Mitigation Measures Avoidance was the main strategy used to minimize impacts to the significant wetlands and woodlands. All components of the Project are sited outside the wetland feature boundaries (4m and 11.4 m setbacks respectively) and within only 4.3% of one significant woodland (2.53 ha). In order to prevent soil erosion, provide dust control and maintain a grassland type appearance under the solar panels during operation, the Construction Contractor will establish a vegetation ground cover at the end of the construction phase, which will be in place for the duration of the Project operations. Routine visual inspections of the Project site for any drainage, erosion or sedimentation issues will be conducted and remediation activities undertaken as required. This includes identification of areas of bare soil and/or the formation of erosive gullies, presence of trash/debris or excess density of vegetation within the passive stormwater conveyance system that would affect flows, and areas of isolated ponding. Remediation measures would include applying sod or seeding, re-grading, removal of trash/debris, and vegetation cutting as required. Saturn Power will implement a vegetation management plan related to the ground cover beneath the solar panels. While the species of vegetation to be established under the panels 5.4

23 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 has not yet been selected, the ground cover beneath the panels should require only minimal maintenance and would assist in preventing the invasion of non-native grassland species. epending on the species selected, the vegetation management plan may include mowing of the site for aesthetic purposes and to ensure vegetation does not grow tall enough to shade the solar panels. It is expected that mowing would occur infrequently, as a fast-growing, tall species is unlikely to be selected as a ground cover. The vegetation management plan will be confined to the perimeter fence within the Project Location for the duration of the Project. Maintenance activities such as infrequent mowing will occur during the day and will avoid the amphibian breeding season (April June). Mitigation measures related to accidental spills are outlined in Section 5.9. Net Effects Feature avoidance eliminates anticipated adverse effects to the wetlands, woodlands and amphibian breeding habitat during operation. Considering the periodic nature of maintenance activities, it is likely that resident herpetiles will adapt to the Project quickly. Consequently, no adverse net effects to the features are anticipated as a result of the Project Other Natural Features The Zone of Investigation is comprised predominately of disturbed industrial land, tilled agricultural fields, woodlands, wetlands, cultural savannah and cultural meadow. Within the Project Location and 12 m Zone of Investigation, 91 species of vascular plants were recorded. Of that number, 58 species (64%) are native and 33 (36%) species are exotic. Of the native species, 98% are ranked S5 (secure in Ontario) and 2% are ranked S4 (apparently secure in Ontario). Woodlands within 12 m of the Project Location have been altered due to farming practices, the existing highway 41 and railway line. There are a total of five woodlands within 12 m of the Project Location. Two woodlands were treated as significant and three woodlands were evaluated as not-significant. There are a total of three wetlands within 12m of the Project Location. Two wetlands were treated as significant and one wetland was evaluated as not-significant. Generalized wildlife habitat for area sensitive woodland breeding birds has also been identified within 12m of the Project Location. No other natural areas are located within the Study Area. Potential Effects The installation of the perimeter fence may interfere with the movement of large mammals. Amphibians and small mammals will continue to be able to pass through this fence structure. 5.5

24 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Indirect impacts to woodland, flora species and vegetation communities are related to dust generation from maintenance traffic, sedimentation and erosion. uring operation of the facility, some materials such as lubricating oils and other fluids associated with solar panel and equipment maintenance have the potential for discharge to the on-site environment through accidental spills resulting in a potential impact to the natural features. Improper disposal of wastes (fluids, containers, cleaning materials) could also have a negative impact on the features. Mitigation Measures The perimeter fence is not expected to significantly disrupt animal movement within the landscape. Amphibians and small mammals will be able to cross the site unimpeded. It is anticipated that larger wildlife, in particular deer, will travel around the site when the perimeter fencing is encountered. In order to prevent soil erosion, provide dust control and maintain a grassland type appearance under the solar panels during operation, the EPC Contractor will establish a vegetation ground cover at the end of the construction phase. Routine visual inspections of the Project site for any drainage, erosion or sedimentation issues will be conducted and remediation activities undertaken as required. This includes identification of areas of bare soil and/or the formation of erosive gullies, presence of trash/debris or excess density of vegetation within the passive stormwater conveyance system that would affect flows, and areas of isolated ponding. Remediation measures would include applying sod or seeding, re-grading, removal of trash/debris, and vegetation cutting as required. Mitigation measures related to accidental spills are outlined in Section 5.9. Net Effects With the application of the above mitigation measures, any adverse effects to natural features during operation of the Project are anticipated to be short-term in duration and spatially limited. Accidental spills will be short term in duration and protocols to minimize their impact are provided in Section WATER BOIES AN AQUATIC RESOURCES Groundwater Based on review of MOE Water Well Records (WWR) and aerial imagery, two water wells are located within 3 m of the Project Location. Nearby private wells were installed at depths of 54 to 64 m below ground surface (BGS). The 212 geotechnical investigation for the Project (Stantec, 212) included 1 boreholes with monitoring wells installed within five (5) of these boreholes. No boreholes reached bedrock. All overburden boreholes but one were noted as dry 5.6

25 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 at the time of drilling. Groundwater monitoring conducted by Stantec in June 212 indicated a water level ranging from.23m BGS to 1.7m BGS. A search for groundwater seeps was a component of both terrestrial and aquatic site investigations conducted for the Project. No groundwater seeps were identified within the Project Location or 12 m Zone of Investigation. Potential Effects There are no expected water withdrawal requirements for the Project as no water is required for operation and maintenance of the Project. Water is not anticipated to be required for solar panel washing as rain water and snow should be sufficient for the cleaning of panels. If required, water for cleaning the panels will be trucked in from an off-site source. Some materials, such as fuel and other fluids associated with construction equipment have the potential for discharge to the on-site environment through accidental spills and thus infiltrate groundwater supplies. A concern identified from the public was potential for contamination from use of herbicides for lawn maintenance. Mitigation Measures Saturn Power will undertake a baseline groundwater quality monitoring program at the on-site monitoring well BH12-1 and the nearest adjacent residential well to characterize existing groundwater quality prior to construction. In the event of a well interference complaint during operation, Saturn Power will complete the following actions: resample groundwater quality and document groundwater levels within the Project Location; collect a water quality sample from private well(s), as applicable; and retain a third party consultant to review available data and determine if adverse effects have occurred as a result of maintenance activity. If adverse effects have occurred due to maintenance, Saturn Power would provide a temporary potable water supply until corrective measures are taken and will comply with MOE Guideline B- 9: Resolution of Groundwater Interference Problems. In the event of a spill, established procedures will be followed as described in Section 5.9, including notifying the MOE s Spills Action Centre as appropriate. 5.7

26 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Vegetation Management Plan will identify methods for minimizing use of herbicides for lawn maintenance such that annual use will be significantly less than a typical agricultural operation. Net Effects Accidental spills would be spatially limited and of short duration and protocols to minimize their impact would be provided in the Emergency Response and Communications Plan. See Section 7. for more information on the Emergency Response and Communications Plan Surface Water, Fish and Fish Habitat In accordance with O. Reg. 359/9, a Water Assessment and Water Body Report was undertaken for the Project and is included under separate cover. The following provides a summary of the potential effects and the associated mitigation measures as described in that report. Water features are shown in Figure 2, Appendix A. There are two water bodies, both unnamed tributaries of Hoople Creek, present within the 12 m zone of investigation. The water bodies are within the jurisdiction of Raisin Region Conservation Authority (RRCA). It was determined through alternative field investigations that these features are water bodies as per O. Reg. 359/9 definition and at minimum provide indirect fish habitat. The Mohawks of Akwesasne additionally identified Hoople Creek and all associated tributaries as important valued features. Potential Effects The current layout proposes a minimum distance of 3 m between the water body boundaries and such project components as solar panels, transformers, inverters and the transformer substation. An existing access road and culvert will be used for access into the main site. Operation activities that have the potential to affect aquatic habitat includes accidental spills and/or leaks. There is also a potential for soil erosion in exposed areas. Mitigation Measures The vegetation management plan that would be implemented during operation would prevent soil erosion through the maintenance of ground cover (see Section 4.3). The routine visual inspections of the site, also described in Section 4.3, would include identification of areas of bare soil and/or the formation of erosive gullies. Remediation measures intended to correct any soil erosion or sedimentation would include applying sod or seeding or re-grading as required. Mitigation measures related to accidental spills are outlined in Section 5.9. Net Effects Accidental spills would be spatially limited and of short duration and protocols to minimize their impact would be provided in the Emergency Response Plan. See Section 7. for more information on the Emergency Response Plan. 5.8

27 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February AIR QUALITY AN ENVIRONMENTAL NOISE The following sections describe the potential effects, recommended mitigation measures, and net effects for air, dust and noise Air Emissions Potential Effects uring the operational phase of the Project, no substantive emissions of air contaminants are expected. Minor localized air emissions would occur from the periodic use of equipment for general repairs, maintenance of panels and from personnel vehicles travelling to and from the property. The Project has no facilities or equipment that will discharge contaminants or pollutants to the air (e.g., exhaust gases from emergency backup diesel generators) during operation of the Project. Sources of localized emissions during operation are considered negligible under O. Reg. 419/5. Mitigation Measures To reduce emissions from equipment and vehicles, several mitigation measures may be employed: Multi-passenger vehicles should be utilized to the extent practical; Company and maintenance personnel should avoid idling of vehicles when not necessary for operations activities; Equipment and vehicles should be maintained in good working order with functioning mufflers and emission control systems as available; and, All operations equipment and vehicles should meet the emissions requirements of the MOE and/or Ministry of Transportation. Net Effects The application of the recommended mitigation measures during operations should limit air emissions to the work areas and limit the magnitude of combustion emissions. As a result, any adverse net effects to air quality from air emissions during operation of the Project are anticipated to be short-term in duration and highly localized ENVIRONMENTAL NOISE uring the operational phase of the Project, the main noise sources are expected to be the ten inverter stations (1 MW inverters and medium-voltage transformer), and the substation transformer. At this point in the design, the final specifications of the equipment manufacturers are not finalized. However, the design team has selected typical and representative 5.9

28 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 specification data for the inverter station equipment and sizing information for the transformers to create a predicable worst-case analysis for the project. A total of 8 receptors within a 1, m radius of the Project Location were included in this model at a height of 4.5 m as required by the MOE. These receptors were included based on a desktop review of the area; both existing dwellings and vacant lots (lots with road access and without a dwelling but which zoning would permit one) are included for assessment purposes. The results were assessed for compliance at the nearest points of reception based on the MOE noise limits outlined in NPC-232 for a Class 3 area. The applicable (exclusionary) limit for the Project was considered as 45 dba for receptors within 5 metres of Highway 41 (defined as Class 2, urban) and 4 dba for receptors beyond 5 metres of Highway 41 (defined as Class 3, rural). Acoustical modelling of the noise sources under reasonable worst-case operating conditions was conducted using a computerized noise model, CANA/A. The model uses the ISO 9613 algorithms to assess the propagation of sound through the atmosphere. Potential Effects The nearest residential Points of Reception (PORs) to a permanent noise source at the Project Location is located to the east of the facility approximately 19 m from the nearest on-site source at the facility. The modelled scenario predicted that the sound level from the Project would result in sound levels below 4 dba at all assessed PORs within Class 2 lands and below 45 BA at all assessed PORs within Class 3 lands. Periodic activities such as general repair and maintenance measures may also cause minimal noise emissions which are not expected to be significant at the nearby receptors. Mitigation Measures The Noise Study has predicted that the environmental noise effect from the operation of the Project is in compliance with the applicable MOE environmental noise guidelines at all receptors. Based on the modeling results, the selection of inverter station equipment with sound levels at or below those emitted from the Advanced Energy Solaron 5 kw inverter station would be predicted to be in compliance with MOE exclusionary limits. The Project would be required to operate according to the terms and conditions of the REA, including noise monitoring (if required). In the event the Project does not operate according to the terms and conditions of the REA, the non-compliant components may be shut down until the problem is resolved. A regular maintenance program would largely mitigate potential effects related to noise from damaged components. 5.1

29 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Net Effects Application of regular maintenance during operations should limit noise emissions and mitigate potential effects related to noise from damaged components. Given that the noise assessment has concluded that the environmental noise effect from the operation of the Project is in compliance with the applicable MOE environmental noise guidelines, no significant net effects are anticipated. 5.5 LAN-USE AN SOCIO-ECONOMIC RESOURCES An assessment of land use in the Study Area was conducted through a review of the Township of South Stormont Zoning By-law (Richard, 211). In addition, visits to the Study Area by the Project team and air photo interpretation were used to identify existing uses of land in the vicinity of the Project Location that could be affected by Project operation. The Study Area is located in a rural area of the Township of South Stormont, United Counties of Stormont, undas and Glengarry. The area is dominated by industrial, agricultural and residential land uses. Socio-economic features within the Study Area include: Highway 41 to the north; A CN Railway line to the south; ickinson rive, a public road right of way to east; Rural residential properties on the north side of the Highway 41; and, Industrial properties on the south side of the Study Area. No areas protected under Provincial Plans and Policies specified in O. Reg. 359/9 are located within the Project Study Area. No recreational facilities, areas or cultural features are currently located within the Study Area. The lands in the Project Location are privately owned and do not include or border local hiking or cycling routes, fishing or conservation areas or parks. There is the possibility of hunting activities occurring within the Study Area Residential Land Use Residential uses include rural residences associated with the agricultural lands and smaller residential properties along the north side of Highway 41. Potential Effects There will be visual impacts from the Project from vantage points within and outside of the Study Area given the change in land use from industrial to solar farm. The vantage points would include Highway 41, ickinson Road, the CN Railway line and residences on the opposite (north) side of Highway 41. The Project will alter the existing viewscape, however the 5.11

30 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 significance of the change/impact is subjective based on an individual s opinion of the Project and the use of industrial land for renewable energy development. Mitigation Measures The solar PV panels will be laminated with anti-reflection coating. Net Effects The anti-reflection coating will minimize glare from the panels and therefore impact to adjacent areas is not anticipated to be a concern. No adverse net effects are expected as a result of the Project Agricultural Lands and Operations Agricultural land-use within the Study Area is dominated by cash crop production. The land within the Project Location is no longer used for agriculture however in recent years was used to grow switchgrass for a nearby biogas facility. No specialty crop or locally significant agricultural lands have been identified in the Project Location. iscussion with previous landowners by Saturn Power determined that although some of the site is considered suitable agricultural land, the property is not a prime agricultural area for common field crop production due to several constraints. For instance, the land was previously disturbed during construction of Highway 41 and a significant number of rocks are scattered throughout the property and most topsoil in the area was removed by a previous landowner for use in the construction industry. Potential Effects Potential effects are related to the change in use from lands with agricultural potential to a renewable energy development. There is also a potential for erosion of topsoil in exposed areas. Mitigation Measures The current landowner does not utilize the property for agriculture, however, the potential use of the site for agricultural activities will cease for the duration of the Project. The vegetation management plan that would be implemented during operation would prevent erosion of topsoil through the maintenance of ground cover (see Section 4.3). The routine visual inspections of the site, also described in Section 4.3, would include identification of areas of bare soil and/or the formation of erosive gullies. Remediation measures intended to correct erosion of topsoil would include applying sod or seeding or re-grading as required. 5.12

31 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Net Effects isturbances to agricultural lands and operations are expected to be temporary (life of Project), reversible, and spatially limited Mineral, Aggregate and Petroleum Resources A review of the MNR s Oil, Gas and Salt Resources database did not identify any petroleum resources within 3 m of the Project Location. In addition lands within the Study Area have not been identified for mineral or aggregate extraction. Potential Effects The operation of the solar farm is not anticipated to have any potential effects on petroleum, mineral or aggregate resources. Mitigation Measures As no effects are anticipated to existing mineral, aggregate, or petroleum resources, no mitigation measures are necessary. Net Effects No adverse net effects are expected as a result of the Project Hunting, Fishing and Gathering Resources The Project Location is largely cleared for industrial use. However suitable habitat remains for hunting and gathering, especially on the west side of the property. Potential Effects There is no potential for creating access to previously inaccessible areas. Sensory disturbance to game species may occur during some maintenance activities due to noise and increased traffic and human activity. A certain level of sensory disturbance to wildlife in the Project Study Area already exists from ongoing agricultural, rural, domestic, and industrial activities. The installation of the 2m to 6m high perimeter fence may interfere with the movement of large mammals. Amphibians and small mammals will continue to be able to pass through this fence structure. Perimeter fence will limit access for harvesting/gathering traditionally used plants and vegetation. 5.13

32 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Mitigation Measures Mitigation measures related to wildlife are identified in Section 5.2.2; fish and fish habitat in Section 5.3.2, and noise in Section Through consultation with the Mohawks of Akwesasne, it was decided that the Environmental Office will be informed in advance of land clearing activities for construction. Community members will have the option of harvesting plants prior to land clearing. Net Effects Maintenance noise effects on games species are anticipated to be temporary and intermittent. Reduced amount of land for gathering/harvesting resources will be for the life of the project but will be across a small portion of land relative to the scale of the local landscape. 5.6 LOCAL TRAFFIC Potential Effects A negligible change in road traffic is anticipated during the operations phase. A small number of light trucks would be required for typical maintenance activities. Project related traffic would be restricted to a limited, defined workforce. The number of vehicles required during operation of the facility would generally be minimal. There may be instances during maintenance activities where excess loads (e.g., solar panel and transformer components) would require special traffic planning. Mitigation Measures Road safety is not expected to be an issue during operations; however the potential for accidents along the municipal roads and on-site cannot be totally disqualified. To ensure public safety, all staff/personnel travelling to/from the project location will abide by all traffic rules and regulations, and will carpool where possible to minimize traffic volume. Although there are no requirements for formal public notification of excess load movements, Saturn Power may provide notification of non-conventional load movements, with potential methods of notification including postings on the Project website. This notification would be provided in the interest of public safety, minimization of disruption of other road users, and good community relations. Net Effects Light truck traffic would increase on some roads during maintenance activities and from personnel vehicles; however this traffic would be short-term in duration and intermittent. 5.14

33 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February LOCAL ECONOMY Potential Effects Operation of the facility is expected to continue for a minimum of 2 years. uring operations, it is expected that approximately two part-time or full-time maintenance staff would be employed. To the extent possible, Saturn Power would source goods and services required for maintenance activities from qualified local suppliers where these items are available in sufficient quantity and at competitive prices. The Mohawks of Akwesasne showed special interest in providing services for the operations/maintenance of the facility. Saturn Power will coordinate with the Mohawks of Akwesasne Economic evelopment Office to ensure that the tender or sourcing for these services are shared with suitable contacts within the community. Local economic benefits would also include a minimum of 2 years of municipal taxes to be paid by Saturn Power. Mitigation Measures As no potential negative effects are anticipated to the local economy, no mitigation measures are necessary. Net Effects The operation of the Project would provide positive income, employment, and fiscal benefits to the local area, including the Municipality. The Municipality would receive ongoing property tax income from the Project. 5.8 EXISTING LOCAL INFRASTRUCTURE Municipal Infrastructure Municipal infrastructure within the Study Area includes ickinson rive and associated road allowance. Saturn Power is committed to working with the United Counties of Stormont, undas and Glengarry and Township of South Stormont to obtain all necessary permits, approvals, and agreements related to the Project. No municipal infrastructure is located within the Project Location. Potential Effects No effects are anticipated during operations of the facility on municipal infrastructure. Mitigation Measures As no potential negative effects are anticipated to municipal infrastructure, no mitigation measures are necessary. 5.15

34 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Net Effects No significant effects are anticipated to municipal infrastructure during operation of the Project Other Infrastructure Other linear facilities and infrastructure located within the Project area include: A CN Railway line runs adjacent to the south side of the Project Location. This railway line is active and regularly used. A TransCanada Pipelines gas distribution pipeline runs approximately 51m away from the Project Location, outside of the Study Area. An existing distribution line owned and operated by Hydro One runs through the Project Location on the south end of the property. Agreements are being finalized between Saturn Power and Hydro One for the distribution line to be relocated off of the property prior to construction. The Provincial Highway 41 is adjacent to the north side of the Project Location, within the Study Area. Project infrastructure and/or construction activities would not require the crossing of navigable waters. Potential Effects No potential effects are expected to the gas distribution pipeline or HONI distribution line. Potential for changes in drainage to impact use of CN Railway and Highway 41. The Project has potential to limit the future expansion of Highway 41 with the installation of structures within the Ultimate Highway Limit. Mitigation Measures esign will ensure that drainage patterns are maintained. Saturn has committed to providing CN Railway an opportunity to review final site plans and drainage plans when prepared. The drainage plans will be submitted to MTO for review under the Building and Land Use Permit Application. The Ministry of Transportation (MTO) was consulted through the REA process. The Project will require a Building and Land Use Permit from the MTO prior to construction, but after detailed design. This permit is required so as to protect the MTO s assets from buildings/structures that could impede future long term expansion plans. The Project has been designed so that required setbacks of fences, roads, structures, solar panels and other project components are sufficiently outside of the Highway 41 Ultimate Highway Limit so as not to interfere with any 5.16

35 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 future expansion plans. This consultation will facilitate acquisition of the Building and Land Use Permit after detailed design is complete. No other potential effects would occur and therefore no mitigation measures are necessary. Net Effects No adverse net effects are expected as a result of the Project. 5.9 WASTE MATERIAL ISPOSAL & SPILLS Potential Effects Waste materials, such as oil, grease, batteries, and a minor amount of domestic waste (i.e. garbage, recycling, and organics), would be generated during standard operation and maintenance activities. Improper disposal of waste material generated during operation may result in contamination to soil, groundwater, and/or surface water resources on and off the Project site. Litter generated during operations may also become a nuisance to nearby residences if not appropriately contained and allowed to blow off site. Hazardous materials on-site are limited to fuel, oils, and other fluids associated with maintenance vehicles, and oils contained within Project components (i.e. transformers). These materials have the potential for discharge to the on-site environment through accidental spills. Mitigation Measures uring operation, Saturn Power and/or the Operation and Maintenance Contractor would implement a site-specific waste collection and disposal management program, which may include good site practices such as: contractors would be required to remove all waste materials from Project sites during maintenance activities; labelling and proper storage of liquid wastes (e.g. used oil and solvents) in a secure area that would ensure containment of the material in the event of a spill; as appropriate, spill kits (e.g. containing absorbent cloths and disposal containers) would be provided on-site during maintenance activities and at the operation and maintenance building; dumping or burying wastes within the Project sites would be prohibited; disposal of non-hazardous waste at a registered waste disposal site(s); if waste is classified as waste other than solid non-hazardous, a Generator Registration Number is required from the MOE and the generator would have obligations regarding manifesting of waste. Compliance with Schedule 4 of Regulation 347 is mandatory when determining waste category; and 5.17

36 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 implementation of an on-going waste management program consisting of reduction, reuse, and recycling of materials. In terms of accidental spills or releases to the environment, undesirable materials on-site are limited to fuel, lubricating oils, and other fluids associated with maintenance activities. Large quantities of these materials would not be stored at the site and do not represent a significant potential adverse effect on the groundwater in the event of accidental spills. Standard containment facilities and emergency response materials would be maintained on-site as required. Equipment maintenance and other potentially contaminating activities would occur in designated areas. As per s.13 of the Environmental Protection Act, all spills that could potentially have an adverse environmental effect, are outside the normal course of events, or are in excess of prescribed regulatory levels will be reported to the MOE Spills Action Centre. Follow-up monitoring /inspections would be implemented in the event of an accidental spill/leak as appropriate. Remedial actions may be required in the event monitoring indicates a negative effect to natural features. Net Effects With the application of the mitigation measures outlined above, no net effects from waste material disposal would occur on-site during operation. 5.1 PUBLIC HEALTH AN SAFETY Potential Effects Given the installation of large scale electrical equipment, there is an inherent risk of fire associated with an accident or malfunction. However, the solar panels and associated equipment result in a negligible increase in fire potential. A chain link fence will be built around the solar farm as per ESA standard. This fence will also act to protect the facility from trespassing and vandalism. uring operation, failure of overhead line poles is a possibility. In the event of a pole failure during operation, a line outage would probably occur, the duration of which would depend on the number of poles affected, the extent of the damages, weather conditions at the time of the incident and the availability of response personnel. It is anticipated that the probability of pole failure occurring during operation is low. However, no poles are currently expected to be installed outside of the perimeter fence. Lastly, a concern identified from the public was potential for contamination from use of herbicides for lawn maintenance. 5.18

37 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Potential Environmental Effects and Mitigation Measures February 213 Mitigation Measures Saturn Power would aim to minimize accidents and malfunctions with proper training and education of staff operating the control system and maintaining the panels on a day to day basis. In addition, the solar panels and associated electrical equipment will be installed and maintained in accordance with applicable safety standards. The primary method of minimizing potential public health and safety risks is with site access restrictions (with the exception of maintenance and emergency personnel). Notification of access restrictions may include No Trespassing signs on the perimeter fencing and entrance gate. Fencing would restrict unauthorized access and additional signage may include, but would not be limited to, signs associated with potential risks at the Project. In addition, the gate will be designed so as to be locked with a padlock from either inside or outside of the gate. Each gate will have a hold back and a cane bolt. Lighting will also be present around the facility; however this lighting will only operate in the event of an emergency. Additional security measures such as security cameras and motion sensor flood lighting may be installed at the discretion of Saturn Power. Municipal emergency response staff would also be trained to appropriately deal with any potential accidents and malfunctions resulting from the operation of the solar farm. Saturn Power has agreed to provide a tour of the facility and appropriate training, if necessary, to Township of South Stormont fire services and volunteer fire staff. Additional equipment beyond what is typically required to respond to electrical fires is not required for fires involving solar PV panels. The Emergency Response and Communications Plan is provided in Section 7.. The primary preventative measure taken to avoid pole failure during operation is at the design stage. Overhead lines must be designed and constructed in accordance with applicable regulatory guidelines. Vegetation Management Plan will identify methods for minimizing use of herbicides for lawn maintenance such that annual use will be significantly less than a typical agricultural operation. Net Effects As a result of the structural integrity and design features of the solar farm in addition with routine maintenance in accordance with applicable safety standards, no significant adverse net effects are anticipated to public health and safety during operation of the facility. 5.19

38 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 6. Environmental Effects Monitoring Plan The environmental effects monitoring plan for Project operation has been designed to monitor implementation of the proposed protection and mitigation measures and to verify compliance of the Project with O. Reg. 359/9. Environmental monitoring would provide data on key functions of natural environment and socio-economic features that may be affected during construction or operation of the Project, and on the effectiveness of mitigation strategies measures implemented as part of the Project. The monitoring procedures noted herein are linked to the potential effects and protection and mitigation measures discussed throughout Section 5.. The environmental effects monitoring plan associated with construction activities, including a description of post-construction monitoring, is provided in the Construction Plan Report.

Maintenance activities such as infrequent mowing will occur during the day and will avoid the amphibian breeding season (April June). Contractors would remove all waste materials from the construction site during maintenance activities. Liquid wastes will be properly labelled and stored in a secure area. As appropriate, spill kits would be provided on-site during maintenance activities. umping or burying wastes within the Project site would be prohibited. Non-hazardous wastes will be disposed of at a registered waste disposal site. If waste is classified as waste other than soil non-hazardous, a Generator Registration Number is required from the MOE and the generator would have obligations regarding manifesting of waste. Implementation of an on-going waste management program. Standard containment facilities and emergency response materials would be maintained on-site as required. Equipment maintenance and other potentially contaminating activities would occur in designated areas. As per s.13 of the Environmental Protection Act, all spills that could potentially have an adverse environmental effect, are outside the normal course of events, or are in excess of prescribed regulatory levels should be reported to the MOE Spills Action Centre. Tree cutting conducted in accordance with any tree cutting by-law, if applicable. Establishment of a vegetation ground cover. Contractors would remove all waste materials from the construction site during maintenance activities. Liquid wastes will be properly labelled and stored in a secure area.

Non-hazardous wastes will be disposed of at a registered waste disposal site. If waste is classified as waste other than soil non-hazardous, a Generator Registration Number is required from the MOE and the generator would have obligations regarding manifesting of waste. Implementation of an on-going waste management program. Standard containment facilities and emergency response Any adverse effects are anticipated to be short-term in duration and spatially limited.

45 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT 7. Emergency Response and Communications Plan The following sets out a general description of the actions to be taken during all Project phases to inform the public, Aboriginal communities, the municipalities, and relevant government ministries regarding activities occurring at the Project site (including emergencies), means by which stakeholders can contact Saturn Power, and means by which correspondence sent to Saturn Power will be recorded and addressed. Saturn Power will create an Emergency Response and Communications Plan for use by employees, which will include up-to-date contact information and will be maintained at an accessible location during all Project phases. The Emergency Response and Communications Plan will be reviewed by Saturn Power during each phase of the Project. Notification of any changes to the Emergency Response and Communications Plan would be provided to relevant stakeholders as outlined in Section EMERGENCY RESPONSE Saturn Power will communicate and confirm the Emergency Response Plan with the Township of South Stormont and United Counties of Stormont, undas and Glengarry Emergency Services epartments including police, fire and ambulance services. Regular contact with the municipal emergency response staff will ensure that they are aware of the status of construction on site and understand how to deal with any potential accidents and malfunctions resulting from the operation of the solar farm. Additional equipment beyond what is typically required to respond to electrical fires is not required for fires involving solar PV panels. Saturn Power has committed to providing a tour and appropriate training, if necessary, to Township of South Stormont fire services and volunteer fire staff. The Emergency Response and Communications Plan will be implemented throughout the life of the Project and will be updated to include key contact information for emergency service providers, a description of the chain of communications and how information would be disseminated between Saturn Power and the relevant responders. This information will be obtained during consultations with the Town s and County s Emergency Services epartments. In the event of an emergency, Saturn Power will initiate the following Emergency Response Plan and will directly contact (via phone or in-person) Project stakeholders who may be directly impacted so that the appropriate actions can be taken to protect stakeholders health and safety. The purpose of the Emergency Response and Communications Plan is to establish and maintain emergency procedures required to effectively deal with an emergency situation and to minimize potential effects. Potential emergency scenarios that could occur on the Project site include fire, personal injury and accidental spills. The following sections provide procedures to follow in the event of these potential emergency scenarios. 7.1

46 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Emergency Response and Communications Plan February 213 All Project personnel will be trained in the emergency response and communication plan procedures outlined. Any non-project personnel visiting the site will need to be accompanied by Project personnel when on the site, will be required to attend and participate in safety awareness before entering the site, and must wear appropriate personal protective equipment when on the site. uring operation of the Project the site will be monitored using the SCAA system on a realtime basis, 24 hours a day and 7 days a week. In the event of an emergency detected on the site, Saturn Power will respond by sending Project personnel to the site to address the emergency and communicate with the appropriate authorities Fire Fire extinguishers will be located throughout the Project site in personnel vehicles and at health and safety points (e.g. the entrance to the site, the substation, etc.); these points will be determined by the EPC Contractor for the construction phase and by the Operations Manager during the operation phase. If a fire occurs on the site, Project personnel will follow all safety procedures and attempt to extinguish the fire, only if it is safe to do so. Project personnel will not attempt to extinguish the fire if there is a potential risk to personal safety. If personal safety is a concern, the Project area will be evacuated immediately and 911 will be called to contact the local fire department (and ambulance if required). If there is potential for the fire to spread offsite, the Project personnel will notify adjacent property owners. All Project personnel that will be on-site during the life of the Project will be trained in the proper procedures for dealing with a fire and on how to use a fire extinguisher. For the duration of operation of the Project, a sign will be placed in a visible location on the entrance gate to the Project site. This sign will provide important instructions in case of an emergency situation. It will identify that the passerby should call 911 as well as the provided Project phone number. In the event of an emergency, and Project personnel on-site will contact 911 and the Operations Manager. A record of all incidents on the site will be kept on file. The record will include date of the incident, date of reporting, name of reporter, description of the incident, cause of the incident, actions taken, communications to internal and external groups and follow-up required. 7.2

47 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Emergency Response and Communications Plan February Personal Injury First-aid supplies and maps providing the location and routes to the local hospital will be kept on-site for the life of the Project. A list of Project personnel certified in first-aid and CPR will be posted with the first-aid supplies on-site. In the event of a personal injury on-site, the injured worker will be treated if it is a minor injury; otherwise, the person will be transported to the hospital directly or by ambulance. If an ambulance is required for an injury, Project personnel will call 911 and assist the injured worker as required until emergency personnel arrive on-site. In the event of an injury, the EPC Contractor (during construction and decommissioning) or the Operations Manager (during operations) will be immediately notified. A record of all incidents on the site will be kept on file. The record will include date of the incident, date of reporting, name of reporter, description of the incident, cause of the incident, actions taken, communications to internal and external groups and follow-up as required by Health and Safety Regulations Accidental Spills The Ministry of the Environment s Spills Reporting A Guide to Reporting Spills and ischarges (May, 27) provides the procedures to be used in the event of an accidental spill on the Project site. The Environmental Protection Act and Ontario Regulation 675/98 provide the definition of spills that are required to be reported. The most likely sources of potential accidental spills on-site include portable washroom sewage, transformer oil, vehicle fuel or oil or hazardous material stored on-site. Accidental spills may result from the improper handling of materials or a leak from spill containment material. Measures to prevent potential effects of accidental spills on the natural environment can be found in the Natural Heritage Assessment and Environmental Impact Study. Project personnel on-site during the life of the Project will be trained to properly respond to accidental spills. The following procedures will be followed if an accidental spill occurs: Potential health and safety issues will be identified before entering the scene of the spill. If safe to do so, the spill will be stopped. If the spill could cause harm to human health, 911 will be called immediately and Project personnel will notify anyone who could be potentially impacted. The appropriate Project personnel will be notified of the spill (EPC Contractor during construction and decommissioning and the Operations Manager during operations). A spill kit, located on-site, will be used to clean and contain the spill, if safe to do so. An outside spill response contractor will be contacted to help clean up major spills beyond the spill kit s capabilities, if required. 7.3

48 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Emergency Response and Communications Plan February 213 The spill will be reported to the MOE s Spills Action Centre and any other relevant outside agencies, as required. Spill kits (e.g. containing absorbent cloths and disposal containers) will be located at health and safety points for the life of the Project. MOE s Spills Action Centre will be notified if any of the following types of spills occur on-site: Non-approved releases/discharges to the land, air or water. Vehicle fluid discharges greater than 1 L. Electrical transformer releases of mineral oil greater than 1 L. Any discharges to waterbodies (e.g. sediment). The MOE Spills Action Centre can be contacted 24-hours a day through their toll-free number: This phone number will be posted on the entrance gate to the Project site and will also be available with the other important phone numbers at each health and safety point on the Project site. All accidental spills will be documented and the reports will be provided to the MOE, as required. Reporting will include the date of the incident, date of reporting, name of reporter, description of the accidental spill, cause of the accidental spill, type and amount of spill, actions taken, disposal of contaminated material, communications to internal and external groups, and follow-up as required. Copies of the detailed Emergency Response and Communications Plan will be kept on-site (construction office trailer during construction and control building during operation) and will be accessible to on-site employees at all times. 7.2 NON-EMERGENCY COMMUNICATIONS Project Updates and Activities Saturn Power will continue contact with Project stakeholders (public, Aboriginal communities, and the municipalities) during the operation of the Project for as long as this seems an effective two-way channel of communication. Methods of communication could include providing Project updates on the Project website ( letters, newsletters, newspaper notices, and/or direct contact. As a long-term presence in the community, Saturn Power will continue to develop contacts and to develop local relationships and channels of communication. Should federal, provincial or municipal agencies require notification, the information will be sent directly to them by , mail or direct contact (via phone or in person). Saturn Power will keep a record of all communications on file. 7.4

49 AVI BROWN SOLAR PARK ESIGN AN OPERATIONS REPORT Emergency Response and Communications Plan February Complaint Response Protocol A sign will be posted during all phases of the Project at the gate of the facility which will include a telephone number for contacting Saturn Power. The telephone number, along with the mailing and/or address would also be posted on the Project website ( and provided directly to the Town, County and MOE. The telephone number provided for the reporting of questions, concerns and/or complaints would be equipped with a voice message system used to record the name, address, telephone number of the complainant, time and date of the complaint along with details of the complaint. All messages would be recorded in a Complaint Response ocument to maintain a record of all complaints. Saturn Power would endeavour to respond to messages within 48 hours. All reasonable commercial efforts would be made to take appropriate action as a result of concerns as soon as practicable. The actions taken to remediate the cause of the complaint and the proposed actions to be taken to prevent reoccurrences of the same complaint in the future would also be recorded within the Complaint Response ocument. Correspondence would be shared with other stakeholders, such as the MOE, as required and/or as deemed appropriate. Ongoing stakeholder communication would allow Saturn Power to receive and respond to any general community issues on an ongoing basis. 7.5
