6 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Introduction January 17, INTRODUCTION Barlow Energy Centre Limited Partnership (the Proponent), is proposing the development of a 10 megawatt alternating current (MWac) solar energy generating facility, known as the Barlow Solar Energy Centre (the Project) approximately 10 kilometres (km) west of the city of Cornwall. The Project Location is primarily in the Township of South Stormont, United Counties of Stormont, Dundas and Glengarry, Ontario, however the Point of Common Coupling will be located within the road allowance of Cornwall Centre Road, in the City of Cornwall, Ontario. The Project will require a Renewable Energy Approval (REA) as per Ontario Regulation (O. Reg.) 359/09 - Renewable Energy Approvals under Part V.0.1 of the Act, under the Environmental Protection Act (MOECC 2009, amended 2016). The Proponent is proposing to develop, construct and operate the Project on 38 hectares (ha; 94 acres) of land (i.e., size of Project Location) in response to the Government of Ontario s Large Renewable Procurement initiative to promote the development of renewable electricity in the province. The Project will be located on parts of lots 20 and 21, Concession 4 on privately-owned land, leased for a period of 20 or more years. The Project Location is bounded to the south by Cornwall Centre Road, and to the west, north and east by undeveloped woodlands and scrubland. A Trans Northern Pipeline Inc. (TNPI) pipeline and Hydro One Networks Inc. (Hydro One) transmission line bisect the Project. A map showing the location of the Project is provided in Figure 1, Appendix A. Figure 2 shows a conceptual Project component layout (Appendix A). The Proponent has retained Stantec Consulting Ltd. (Stantec) to prepare a REA application, as required under O. Reg. 359/09. The proposed solar PV grid connected system would be considered a Class 3 Solar Facility under O. Reg. 359/09, s. 4. The area surrounding the Project is generally agriculture in nature. The area s acoustical environment is best described as a Class 3 (Rural) area as per MOECC s guideline publication Environmental Noise Guideline (NPC-300). The existing acoustic environment is expected to be dominated by natural ambient noise with sporadic contributions from road and rail sources. This assessment considers 72 receptors within a setback of approximately 1 km of the Project Location boundary as required by the MOECC. 1.1 BACKGROUND As outlined above, the Project will require a REA as per Ontario Regulation (O. Reg.) 359/09 - under Part V.0.1 of the Environmental Protection Act (MOECC 2009, amended 2016), which stipulates requirements for renewable energy projects. According to the project classification provided under Section 4 of O. Reg. 359/09, all ground mounted solar facilities with a name 1.1

7 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Introduction January 17, 2017 plate capacity greater than 10 kw require a noise study report to support REA applications. Section 13 of O. Reg. 359/09 requires that noise studies for Class 3 facilities should be conducted in accordance with Basic Comprehensive Certificate of Approval, April 2004 and subsequent amendments. This Acoustic Assessment Report has been prepared based on the requirements described in the current MOECC noise forms and guidelines including the following documents: NPC-300, Environmental Noise Guideline. Basic Comprehensive Certificates of Approval, User Guide v2.0, Appendix A, Supporting Information to be Submitted for an Acoustic Assessment Report or Vibration Assessment Report Required by a Basic Comprehensive C of A, April

8 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Facility Description January 17, FACILITY DESCRIPTION The Project Location is located on up to two parcels of privately-owned land, totaling approximately 38 ha on the north side of Cornwall Centre Road, west of Power Dam Drive. An area map showing the Project Location and property boundaries are provided in Figure 1, Appendix A. Figure 2 shows a conceptual Project component Layout (Appendix A). 2.1 FACILITY LAYOUT The Project is being designed and constructed to generate 10 MW of power. The basic Project components include: solar panels inverters (converting solar panel output from direct current [DC] to alternating current [AC]) inverter step-up transformers (converting AC voltage to grid voltage levels) electrical cabling access roads perimeter fencing parking/storage areas main facility substation and control building. The Project will have a nameplate capacity of 10 MW and will consist of photovoltaic panels. Panels would be installed on galvanized steel and/or aluminum racks in rows to capture sunlight. The orientations of these panels are not expected to contribute to the sound propagation. The generated electrical power from these panels will be routed through a system of inverters and inverter step-up transformers, which are considered noise sources at the facility. The facility will include four (4) stations (each with one or more inverter(s) [2.5 MW each] and inverter step-up transformer(s) [3 MVA each]. Each station is expected to serve the surrounding cluster of solar panels. At each station, the voltage level will be raised to 44 kv (if no main power transformer is integrated in the final project design) or either 27.6 kv or 34.5 kv (if a main power transformer is integrated in the final project design) by the inverter step-up transformers co-located with each inverter. The inverters are modular units prepackaged with their own casing. The electricity will be transported from the inverter stations to a single substation via underground cables. From the substation, the Project will be connected to the distribution grid via the connection line. One 12 MVA main power transformer will also be located within the substation location. Currently, there are 4 solar panel layouts under consideration. These layouts are for ground fixed tilt (GFT) and horizontal single axis trackers (HSAT) racking types. 2.1

9 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Facility Description January 17, OPERATING SCENARIO The Project will operate throughout the year during the daylight hours. Due to extended daylight hours during summer months, the facility could operate outside guideline daytime period, (i.e., 7:00 AM to 7:00 PM). The facility is expected to operate 7 days a week throughout the year. The sources of noise are the inverters, inverter step-up transformers and a main power transformer located within the substation area. It was conservatively assumed that all equipment units will operate at full rated capacity during the predictable worst case hour. The source locations are shown in Figure 3, Appendix A. There are four possible locations for each of the four inverter stations and substation. These possible locations form a polygon and are considered as a polygon multiple scenario in this assessment. 2.2

10 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Noise Source Summary January 17, NOISE SOURCE SUMMARY 3.1 NOISE SOURCES The noise sources for the facility are the stations (4 stations, each with one or more inverter[s] and with one or more inverter step-up transformer[s]) and the main power transformer located within the substation. As discussed, the inverters are modular units and housed in a prepackaged casing. The inverter step-up transformer associated with each station is to be located near the inverters. Depending on the orientation of the station, it is expected that the inverter will provide some shielding to the inverter step-up transformer and vice versa. However, this assessment conservatively assumes that inverters or inverter step-up transformers provide no attenuation to inverters or inverter step-up transformers. In other words, the assessment considers inverters and inverter step-up transformers will be placed outside without any shielding from one another. Thus the facility s dominant noise sources would consist of noise radiating from: 4 inverters each with 2.5 MW (Power Electronics HEC 1500V model) inverters 4 inverter step-up transformers rated at 3.0 MVA 1 main power transformer rated at 12 MVA at the substation location. Sound levels for the inverters were based on equipment manufacturer submittals (included in Appendix B). The sound level for the transformers were estimated based on the provided rating, and dimensional data from typical transformer from other similar projects. Each of the inverter units is represented with an overall sound power level of 91.7 A-weighted decibels (dba; including 5 db increase for tonality) and the associated inverter step-up transformer is represented with a sound power level of 82.4 dba (including a 5 db increase for tonality). The sound power level for the 12 MVA main power transformer was estimated at 94.6 dba (including a 5 db increase for tonality). The equipment specifications and data are provided in Appendix B. As discussed, all sources (inverters, inverter step-up transformers and main power transformer) include a tonality penalty as per MOECC s guideline requirements. The solar panels would be installed in arrays at a height of approximately 1 m or more above grade and would be installed at an angle to capture sunlight. Therefore, the lower portions of these noise sources are expected to be shielded by the solar panels. However, the assessment does not consider the shielding provided by these panels to be conservative. Four conceptual layouts were considered; each of these layouts considers different locations for inverter/inverter step-up transformer locations as well as substation locations. These four scenarios were assessed separately under the polygon multiple scenario as follows: 1. Polygon Multiple Scenario #1: All sources are northeast corner of respective polygons 2. Polygon Multiple Scenario #2: All sources are southeast corner of respective polygons 3.1

11 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Noise Source Summary January 17, Polygon Multiple Scenario #3: All sources are southwest corner of respective polygons 4. Polygon Multiple Scenario #4: All sources are southeast corner of respective polygons This provides a reasonable worst case scenario with respect to the polygon approach. The sources discussed above for this Project are summarized below (Table 3.1) and illustrated in Figure 3 (Appendix A). All sources are assumed to have continuous, steady sound emissions when operating. 3.2 SOUND CHARACTER ADJUSTMENT The MOECC s guideline NPC-104 outlines that the sources with distinct sound characteristics be penalized in the assessment. In accordance with this guideline and recent MOECC communications, the resulting noise emissions associated with inverter step-up transformers and inverters were penalized with a 5 db penalty to account for a potential hum from inverter stepup transformer coils and all inverters. Transformers sometimes exhibit tonal characteristics, which may not be present in small transformers. However, a 5 db penalty was conservatively applied to all inverter step-up transformers in the assessment (i.e., applied to each inverter step-up transformer at each station as well as the 12 MVA main power transformer). 3.2

14 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Points of Reception January 17, POINTS OF RECEPTION Figure 4 (Appendix A) shows the Project Location and the PORs. The assessment considers a total of 72 PORs (Vacant, Commercial, and Existing PORs) in all directions within approximately 1 km of the Project Location. There was a total of 72 receptors identified; 16 of which are currently used for commercial purposes. However, for the purpose of completeness, these 16 receptors were also identified for the assessment. The receptors are as follows: PORs currently used for commercial purposes are identified as CPOR##, where ## represent a unique identification for the receptors. There are 16 CPORs. Existing residential dwellings are identified as EPOR##, where ## represents a unique identification for the receptors. There are 36 EPORs. Currently vacant lots and are identified as VPOR##, where ## represents a unique identification for the receptors. There are 20 VPORs. Among the receptors, the nearest to the Project is VPOR29 and is a vacant lot receptor (approximately 220 m southeast of the Project Location). All receptors were modeled using a height of 4.5 m above grade. The list of studied receptors is summarized in Appendix C. For the purposes of this report, four PORs are shown in Table 4.1 below. These 4 receptors were selected to represent the closest POR southeast, south, southwest and west of the Project Location. The PORs to the north are well separated and are provided in Appendix C. The locations and distance to the nearest inverter or inverter step-up transformer of these PORs are provided in Table 4.1. Table 4.1: Nearby Points of Reception POR ID Description X Coordinates CPOR18 POR to the West Y Receptor Height (m) Approximate Distance to Nearest Facility Equipment (m) VPOR29 POR to the Southeast VPOR45 POR to the South CPOR46 POR to the Southwest The lands immediately south of the facility (and south of Cornwall Centre Road) are owned by Hydro One (road allowance) and the City of Cornwall (dump or transfer station). The current land use zoning designation does not permit noise sensitive buildings and therefore no receptors are included on these properties (Figure 4 and Appendix E).

15 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Points of Reception January 17, 2017 Similarly, an abandoned commercial building is located to the southwest within lands zoned commercial (Figure 3 and Appendix E). This property is not considered suitable for a noise sensitive receptor. The property located east of the Project Location (Figure 3 and Appendix E) is currently zoned as flood plain and is not considered suitable for a noise sensitive receptor. Therefore, a vacant lot receptor was not considered. 4.2

16 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Noise Assessment Criteria January 17, NOISE ASSESSMENT CRITERIA 5.1 MOECC GUIDELINE LIMITS As the facility and a number of surrounding receptors are located adjacent to Cornwall Centre Road, west of Power Dam Drive, the sounds from the traffic are expected to occasionally influence the sound levels on PORs near the roadway. The MOECC noise criteria use the proximity of receptors to human-made sources of sound such as traffic or industry and their presence throughout the day to define the sound level limits for different areas. However, because the traffic noise is expected to be non-constant, the study area would be dominated by the natural ambient sound the majority of the time, with increases in noise during traffic passby events. Receptors within 1 km of the Project Location are considered to be located in a Class 3 (or rural) area. In a Class 3 area, the sounds of the ambient environment are expected to be dominated by natural sounds with little or no road traffic. The MOECC publication NPC-300 provides sound level limits for Class 3 areas. Publication NPC-300 requires that the one-hour equivalent sound level (Leq (1 hour)) in dba from the proposed stationary noise sources should not exceed the applicable sound level limit at a noise-sensitive receptor location. The sound level limit is considered to be the lower of the prescribed exclusionary limit for a Class 3 area, or the background sound level. NPC-300 defines the background sound as the sound level caused by sources other than those under assessment (e.g., road traffic, the sounds of nature, etc.). The exclusionary limits for a Class 3 area are: 45 dba for a facility operating between 0:700 and 19:00 hrs (daytime) 40 dba for a facility operating between 19:00 and 0:700 hrs (night-time) 5.2 APPLICABLE LIMITS Ambient monitoring was not conducted in the vicinity of the proposed facility and therefore the MOECC exclusionary limits were applied for this assessment. Since the Project could operate during day and night time hours (e.g., early morning), and no difference is assumed between these operations, the applicable criterion is considered to be the MOECC nighttime exclusionary limit of 40 dba. This limit is also stated in the MOECC publication on solar facilities for Renewable Energy Approval (PIBS 7234e). 5.1

17 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT Impact Assessment January 17, IMPACT ASSESSMENT 6.1 MODELING METHODOLOGY A predictive analysis was performed using the commercially available software package CADNA/A, a computerized version of the algorithms contained in the ISO and standards. This model includes geometrical divergence (distance attenuation), barrier effects due to intervening structures, ground effects, atmospheric absorption, and topography. The model considers a downwind condition, which, for the purpose of analysis, is always from each source location to each POR location. All sound sources (inverter step-up transformers and inverters) that emit into the environment were modeled as point sources. Topography was included in the model; however, the terrain is relatively flat and topography was not expected to influence the predicted results. No shielding nor obstacles were included in the model; however, the inverters are modular units that may come with prepackaged casing which will offer some shielding. The facility and surrounding ground surfaces were modeled as a combination of reflective and absorptive surfaces due to the nature of the site. The analysis utilized a ground absorption factor of 0.7 to represent the agricultural land and grass (considered absorptive) observed from imagery of the site. Meteorological assumptions that cause maximum noise transmission are also typical of Ontario values and were used in the model. These included a temperature of 10 degrees Centigrade and a relative humidity of 70%. 6.2 MODELED SCENARIO As described in Section 2.2 (Operating Scenario), the modeled scenario for this assessment consists of all sources running at full capacity for a full hour. This modeled operating scenario assumes that the Project, when operating outside of daytime (07:00 to 19:00 hours), could operate at full capacity. Therefore the night-time operation is considered to be the predictable worst-case scenario relative to the applicable criterion, as presented in Section 6.3. An example of the detailed model calculations is included in Appendix D. 6.3 RESULTS The modelled contribution of each source at the nearest PORs during a predictable worst case condition is provided in Table 6.1 for the polygon multiple scenarios. The sum of these individual sound levels at each POR gives the overall predicted sound level from the facility s unmitigated operation. The results of the overall modeling assessment (the 6.1

21 BARLOW SOLAR ENERGY CENTRE ACOUSTIC ASSESSMENT FINAL DRAFT REPORT 7.0 CONCLUSIONS The predictive analysis based on the polygon multiple scenario presented in this report indicated that the Project noise effects comply with performance limits at all PORs which are situated within 1 km of the Project, without the need for noise control measures. Stantec s conservative assessment predicted that sound levels during the facility s predicted worst case scenario during operation with sources located within the noise polygons presented within this report will meet the MOECC criteria at all applicable PORs. 7.1
