Engineering information, including switching and protection features, is shown on the Proposed Single Line Diagram [Drawing A- 05, Attachment 5] 2.4 PROPOSED CONSTRUCTION OF TRANSMISSION LINES 9L144 AND ALTERATION OF 9L57 21 ATCO Electric proposes to construct a new single-circuit transmission line designated as 9L144 originating from the approved Birchwood Creek 960S Substation [Drawing AO-08a in Attachment 6] to the Yeo 2015S Substation. 22 ATCO Electric proposes to build the 9L144 line on the existing 9L57 right of way. A segment of 9L57 will be moved from the existing right-of-way by removing the structures and conductors on the existing 9L57 line. The 9L57 centreline will shift 29 m southeast of the old 9L57 centreline. Upon the structure removal, the 9L144 line can be constructed in the existing right-of-way. Yeo Substation Project Page 5 Attachment 1 Application Text

14 Application to the Alberta Utilities Commission October PROPOSED TRANSMISSION LINE 9L The proposed 9L144 transmission line would travel northwest from the Birchwood Creek 960S Substation for approximately 200 m (node A1), turn southwest for 1 km (node A3), turn northwest, cross the pipeline rights-of-way (node A5), and terminates at the proposed Yeo 2015S Substation. ATCO Electric is proposing to re-use a portion of existing right of way from 9L57. The proposed transmission line 9L144 will be constructed with new structures. The existing structures on the portion of transmission line 9L57 proposed to be decommissioned will not be reused due to their age, and different line requirements such as heavier conductor and the addition of shield wires for the proposed transmission line 9L144. The Proposed Route is shown on the Proposed Route Mosaic [Drawing AO-08a, Attachment 6]. 24 The proposed 240-kV single-circuit transmission line 9L144 will be a standard three-phase design with one circuit of three conductor wires, one overhead shield wire and one optical ground wire (OPGW) for telecommunication and lightning protection; and will be strung on wood structures built to ATCO Electric s standards for operation at the nominal voltage of 240-kV. The typical structure will be a single-circuit H-Frame structure. Side guys will be used where required due to wet ground conditions. The structures will be approximately 20 m tall, with a typical span length of approximately 175 m between structures. Side guyed structures will be the typical structures used due to wet ground conditions, although these structures may not be required in all areas and side guys will not be utilized unless required. The typical structure is shown on Drawing RS-H- Frame Structure 240SC in Attachment 7. Typical Structure may vary with final design. Design details are summarized in Table 2 below. Table 2: Design Details for Transmission Line 9L144 Design Type Nominal Voltage Line Length Typical 240-kV Wood Pole Structure 240-kV 1.5 km Number of Transmission Circuits 1 Transmission Line Conductor Lightning Protection Typical Structure Height Typical Span Between Structures Minimum Conductor Clearance (Mid-Span) kcmil ACSR Drake 1-48 fibre optical ground wire (OPGW), 1-3/8 steel overhead shield wire (OHSW) 20 m 175 m 6.1 m Yeo Substation Project Page 6 Attachment 1 Application Text

15 Application to the Alberta Utilities Commission October 2014 (varies with location per safety codes) 25 Non-typical structures may be required at locations where lines turn or terminate; or which require longer spans, greater clearance or extra stability such as across wet areas or valleys. These structures may have taller poles; or additional poles, anchors or guy wires (or any combination of these). In all cases, transmission lines would meet or exceed applicable safety regulation requirements. Final structure specifications will be determined following surveys and detailed line design. 26 As per AESO load flow data, the anticipated loading by 2022 will be 18.4 MW. Transmission line losses were calculated to be negligible. Thermal ratings for the transmission line are shown in Table 3. Table 3: Thermal Ratings for Transmission Line 9L144 Conductor Thermal Rating: Normal (85 C Conductor Temperature) Thermal Rating: Emergency (100 C Conductor Temperature) Summer (30 C) Winter (0 C) Summer (30 C) Winter (0 C) Single 795 Drake 404 MVA 516 MVA 437 MVA 554 MVA L144 Transmission Line Alignment and Right-of-Way 27 The proposed transmission line alignment was based on the location of physical and environmental constraints between the proposed Yeo 2015S Substation and the approved Birchwood Creek 960S Substation and was informed by stakeholder feedback obtained through ATCO Electric s participant involvement program [Attachment 3]. 28 Due to space constraints, a minimized right-of-way is proposed for 9L144. In conjunction with adjacent rights-of-ways, this corridor will allow for construction and maintenance access in consideration of structure guying space requirements. The width and structure placements vary with structure type. Typical minimum right-of-way widths for proposed transmission line 9L144 are indicated in Table 4 below. Table 4: Proposed Transmission Line 9L144 Alignment and Right-of-Way Transmission Line (T/L) Route Location Paralleling Existing Pipeline Right of Way Typical Structure Location Centre of existing RoW Minimum Right-of-Way (RoW) Width 12 m on either side of T/L. (24 m total) Yeo Substation Project Page 7 Attachment 1 Application Text

16 Application to the Alberta Utilities Commission October Right-of-way requirements for specific route segments are shown on Cross- Section Drawing A-09 a and b in Attachment In addition to the minimum widths indicated, additional area may be required for: non-typical structures with anchors, guy wires, additional poles and/or wider spacing at deflections or corners.. 31 ATCO Electric will not apply to AESRD for a Vegetation Control Easement (VCE) as the right of way will be bordered on both sides by transmission or pipeline rights-of-way. 2.6 ALTERATION OF TRANSMISSION LINE 9L57 32 ATCO Electric proposes to alter existing single-circuit transmission line 9L57, originating from Livock 939S Substation to the approved Birchwood Creek 960S Substation. The portion of transmission line 9L57 to be altered begins 580 m outside of the Birchwood Substation 960S boundary, directly southeast of the Yeo Substation [Refer to B2 in Drawing AO-08a in Attachment 6]. The proposed transmission line alteration turns southeast for 29 metres (node B4), then travels along 620 m of new right of way and construction until node B6, parallel and directly adjacent to the proposed 9L144 right of way. 33 The centerline of the 620 m 9L57 segment will move southward by 29 m to allow 9L144 to use the previous 9L57 right of way. 34 The electrical specifications for the 9L57 will remain the same as they previously were, except: two shield wires will be added for the newly constructed transmission line segment and the new H-frame structures for the 9L57 line will be centered on a 34 metre wide right-of-way (17 metres on either side of centre line) Transmission Line Alignment and Right-of-Way 35 The proposed transmission line alignment was based on the location of physical, environmental, electrical constraints along the existing 9L57 within the project area and informed by stakeholder feedback obtained through ATCO Electric s participant involvement program [Attachment 3]. 36 Right-of-way requirements for specific route segments are shown on Cross- Section Drawing A-07 in Attachment In addition to the minimum widths indicated, additional area is required for: non-typical structures with anchors, guy wires, additional poles and/or wider spacing at deflections or corners, or where longer spans are required such as at valleys and watercourse crossings; Yeo Substation Project Page 8 Attachment 1 Application Text

17 Application to the Alberta Utilities Commission October 2014 removal of adjacent trees that could potentially fall onto the transmission line. 38 ATCO Electric will apply to AESRD for a Vegetation Control Easement (VCE) as needed along the rebuilt portion of the transmission line 9L57 right-of-way. 39 Additional clearing width is related to adjacent tree heights. Additional tree clearing will be required along most of the Route, with the exception of non-treed wetlands, cutblocks and other pre-existing disturbances. 2.7 SALVAGE OF 240-KV TRANSMISSION LINE 9L57 40 ATCO Electric proposes to decommission and salvage approximately 650 m of existing transmission line 9L57 [Node B2 to C1, Drawing AO-08a, Attachment 6] to allow new transmission line 9L144 to reuse the existing 9L57 right-of-way. ATCO Electric considered reusing the structures for 9L144; however, as the engineering requirements to support the heavier conductor and install shield wires were different for the 9L144 line, the decision was made to remove and replace the structures in the 650 m length. 41 Salvage activities will involve the removal of poles, conductor and any other infrastructure such as guy wires. 2.8 CONSTRUCTION METHODS 42 Project construction consists of three general phases: pre-construction, construction and post-construction, which are summarized in Table 5 and the following sections. As appropriate, ATCO Electric will modify general and standard construction practices depending upon environmental conditions or presence of environmentally sensitive features. Mitigation measures to be employed during Project construction are described in the Environmental Evaluation [Attachment 2] and Environmental Protection Plan [Attachment 9].

21 Application to the Alberta Utilities Commission October 2014 Table 6: Approximate Project Schedule Activity or Milestone Start Completed AUC Approvals October 2014 (application filed) December 2014 (approval issued) Transmission Line Right-of-Way Clearing and Construction January 2015 March 2015 Substation Construction January 2015 December 2015 In-Service Date December Consequences of Delay 51 To meet the scheduled in-service date, ATCO Electric must start substation and transmission line brushing and construction in winter (Q1) Due to wet ground conditions predominant in the Study Area, ATCO Electric must brush and construct during the appropriate conditions. Meeting the in-service date included in this Facility Application depends on a timely approval that permits project execution commencing in winter (Q1) Delays to approvals could result in cost escalation due to unfavorable environmental conditions, such as wet ground, throughout brushing and construction. In order to avoid environmental impacts, project execution in these conditions would require specific mitigation measures, resulting in further cost increases. Delays in approvals may also result in a longer construction period, resulting in further cost increases and a delay to the proposed in-service date. 53 The transmission line connection from the Birchwood Creek 960S Substation to the Yeo 2015S Substation is required to increase bitumen transportation capacity and support oilsands activities in the area. Meeting the in-service date included in this Facility Application at minimal cost depends on a timely approval that allows for project execution commencing in winter (Q1) The financial impact of schedule delays and lost production to the customer would be potentially significant PROJECT COST ESTIMATE 54 The cost estimate for the scope of the Project work, as detailed in ATCO Electric s Proposal to Provide Service submitted to the AESO, is provided in Table 7.

23 Application to the Alberta Utilities Commission October ROUTE SELECTION 3.1 STUDY AREA 55 The Project is located in northeast Alberta within the Boreal Forest Natural Region Lower Boreal Highlands Central Mixedwood Subregion. The Study Area is located in the Regional Municipality of Wood Buffalo as shown on the Regional Map [Drawing A-01, Attachment 4]. The Project also falls within the Lower Athabasca Regional Plan (LARP) area. The Study Area is located predominately in forest and wetlands as shown on the Forest Capability and Vegetation Features Map and the Wetlands Map [Drawing A-11a and A-11c, Attachment 8] and discussed in Attachment 2. The topography in the Study Area is generally flat to undulating; the land use is predominantly oil and gas development. 56 ATCO Electric s route selection process started with the identification of a Study Area that met the technical requirements of the Customer s requirements, AESO s direction and accounted for geographic [Drawing A-11d], environmental [Drawing A-11b and c, Attachment 8], and land use constraints [Drawing A-11d, Attachment 8]. A sufficient geographic area was selected in order to ensure that sensitive environmental features and land constraints were identified. These constraints are further explained in the Environmental Evaluation [Attachment 2]. 57 ATCO Electric compiled baseline spatial information for the defined Study Area and subsequently developed a project-specific dataset of landscape features relevant to the Study Area with ortho-mosaic background. The applied datasets and mosaics were used to identify broad constraints and serve as a basis for field reconnaissance work. Datasets utilized to define the Study Area for the Project included the following: Roadways including primary highways, secondary highways, major roads, and local roads; Existing transmission facilities; Populated areas including hamlets and larger communities; Oil and gas facilities including pipelines, surface wells, batteries and pump stations; Environmentally Significant Areas; Caribou and Key Wildlife and Biodiversity Zones; Parks and Protected Areas including natural areas, provincial parks, national parks, provincial recreation areas, wilderness areas, ecological reserves, and heritage rangeland; Yeo Substation Project Page 15 Attachment 1 Application Text

24 Application to the Alberta Utilities Commission October 2014 Historical Wildlife Observations from the Fisheries and Wildlife Management Information System (FWMIS); Alberta Vegetation Index that indicated vegetation growth throughout the Study Area; Planned transportation networks; Affected leaseholder development plans; Wildlife constraints; Historical Resource Values on lands that either possess known historic resources or have high potential for their presence, including archaeological, paleontological, historical, natural, and cultural resources; and Watercourses, water bodies, wetlands, and muskeg. 58 The Study Area was developed by examining constraining physical, electrical and environmental features. The Study Area was limited due to the small scope of the project. The Study Area extends generally 3 km in lateral directions from the Birchwood Creek 960S Substation and new customer facility. Existing linear disturbances within the Study Area, such as pipelines and a transmission line, presented opportunities to parallel existing facilities and minimize new disturbances. 59 The Study Area does not contain any significant viewpoints and agricultural or residential land uses [Drawing A-08, Attachment 6; Drawing A-11d, Attachment 8]. 3.2 LAND USE PLANS AND POLICIES 60 The following planning processes are relevant to the Project, and further stressed the importance of following the routing and siting criteria utilized by ATCO Electric: Lower Athabasca Regional Plan (LARP) 61 The LARP includes Regional Outcomes that incorporate the coordination of infrastructure development and integrated land management. This provincial planning policy document reinforces AESRD s position that utilizing existing linear disturbances should be one of the main routing criteria for the Project. The Project is consistent with the LARP in the following ways: Government Agencies, industrial landholders, and trappers were consulted in the routing process and all provided input on the Project. The LARP states that infrastructure development should utilize the Yeo Substation Project Page 16 Attachment 1 Application Text

25 Application to the Alberta Utilities Commission October 2014 minimum amount of land possible, and that integrated land management between industrial users is to be implemented. ATCO Electric has sought to follow existing linear disturbances while avoiding other constraints including wetlands, water crossings, and industrial facilities wherever practicable. ATCO Electric has worked closely with large-scale industrial operators in the area to integrate transmission line route planning with other current and planned industrial activities. The LARP emphasis on engaging First Nations in the planning process was achieved when developing the Project routing and siting options. ATCO Electric engaged three First Nations identified as potential interest holders, based on the direction given by AESRD. Through information sharing, consultation and collaboration, ATCO Electric strived to understand First Nation issues and concerns and incorporate them into the planning process in order to minimize impacts wherever reasonably possible. Air emissions from the Project will not cause ambient air quality conditions to exceed the triggers or limits detailed in the air quality management framework of the LARP. Depending on weather and ground conditions, ATCO Electric may withdraw water to assist in freezing in work areas. If this is required, ATCO Electric will obtain the necessary regulatory approvals in that regard. The Project does not require the use of groundwater. 62 The Study Area does not include any Provincial Parks, Public Land-Use Zones, Provincial Recreational Areas, Public Land Areas for Recreation/Tourism, or Lakeland Country Iconic Tourism Destination Areas found within the Lower Athabasca Regional Plan (LARP) area. 63 The Comprehensive Regional Infrastructure Sustainability Plan for the Athabasca Oil Sands Area (CRISP) describes the province s mandate of integrating multiuse corridor planning and incorporating extensive consultation in the Athabasca Oil Sands area for proposed future projects. The Project is consistent with the CRISP Municipal Development Plan 64 The RMWB s Municipal Development Plan (MDP) includes Regional Growth Management Directions. Direction 3.1 states that the municipality will work with the Government of Alberta to support integrated resource management and planning practices. Furthermore, the municipality aims to limit development along Yeo Substation Project Page 17 Attachment 1 Application Text

26 Application to the Alberta Utilities Commission October 2014 streams, lakes, rivers, and other environmentally sensitive areas. The Project supports the MDP. 65 The Study Area is located outside of any future growth nodes, conservation areas or potential recreation and tourism areas defined in the Municipal Development Plans (MDP) for the RMWB. 3.3 GENERAL SUBSTATION SITING CRITERIA 66 General criteria considered throughout the substation site selection process included: Sufficient land base for substation development, incoming transmission lines and outgoing distribution lines; Consideration for future development of the substation; Relatively flat terrain to reduce the amount of grading and potential impacts to surface and subsurface drainage patterns; Well-drained soils; Adequate access for construction, and permanent, all-weather access for operation; Avoidance of encroachment on surrounding industrial development; and Avoidance of environmentally sensitive areas. 67 Additional criteria used to select the Yeo 2015S Substation included proximity to the customer s future development and avoidance of future expansion areas. Due to the nature of the Customer connection, a substation site adjacent to the future development area was highly favored. 3.4 GENERAL TRANSMISSION LINE ROUTING CRITERIA 68 Key criteria for transmission line routing include: Minimizing impacts with other land uses such as residences, built-up areas, oil and gas facilities, and airstrips; Using existing linear developments to minimize new disturbance and clearing; Following existing transmission lines where possible; Following existing road rights-of-way where possible, for access and to reduce new clearing and to avoid environmental impacts; Keeping routes as straight as possible to reduce transmission line length and costly corner structures; Yeo Substation Project Page 18 Attachment 1 Application Text

27 Application to the Alberta Utilities Commission October 2014 Minimizing length along environmentally sensitive areas such as watercourses, recreation areas, parks, campgrounds and wildlife habitat; and Minimizing length through wet areas and steep slopes for better access and to reduce environmental impacts. 69 ATCO Electric worked closely with AESRD on the routing and siting of the Project, ensuring that the routing and siting of this project was consistent with LARP. 3.5 CONCEPTUAL ROUTE AND SITE DEVELOPMENT 70 The process of developing a substation site was based on an evaluation of siting opportunities and constraints (i.e., features that constrain or prevent the development in a particular location) within the defined Study Area. 71 Numerous field reconnaissance surveys were completed within the Study Area in order to verify the accuracy of available datasets and identify additional features that were not digitally available. Field reconnaissance was completed via foot travel. Features typically recorded include the following: Communication towers Industrial developments Oil and gas facilities Recreational areas Roadways Trapper cabins Slumping or eroding soils Steep slopes Utilities Wetlands Waterbodies Other constraints, including treed areas 72 Conceptual routing and siting opportunities were identified using available datasets and mosaics and using information collected during field reconnaissance and information gathered in early consultations with industry and agencies. Existing industrial development, future development, and existing Yeo Substation Project Page 19 Attachment 1 Application Text

28 Application to the Alberta Utilities Commission October 2014 electrical and pipeline infrastructure limited routing and siting options in the Study Area. 73 ATCO Electric has completed the AESRD recommended environmental assessments as part of the Environmental Evaluation [Attachment 2]. Field assessments that were conducted outside of two of AESRD s recommended environmental timing windows for wildlife studies. Based on recommendations by the environmental consultant, additional studies were performed which confirmed low risk to wildlife, including a non-auditory amphibian survey and common nighthawk survey. Information gathered from the environmental assessments conducted for the Birchwood Creek 960S Substation was also used to supplement environmental surveys. 74 A number of opportunities for conceptual substation sites were considered early in the Project. ATCO Electric investigated a number of routing and substation siting opportunities in close proximity to the customer s future development. Many of those sites were deemed unfavourable as a result of the following limitations: Engineering constraints and feasibility; Limited access from existing and future roads; Future expansion of transmission facilities; Increased fragmentation of habitat and landscape; Existing workcamps; Unfavourable soil and subsoil conditions; Unfavourable topography; Increased line length and footprint; Additional space required for current and future development; and Distance from the customer s future development. 75 Although multiple conceptual routing options were considered early in the Project, many were deemed unfavourable as a result of the following limitations: Increased fragmentation of habitat and landscape Increased transmission line length Increased environmental impacts Increased number of transmission line crossings; and Increased impacts to future industrial development Yeo Substation Project Page 20 Attachment 1 Application Text

29 Application to the Alberta Utilities Commission October The selection of a new substation site requires considering factors such as suitable site conditions (level, well-drained), good access, sufficient space, adequate setback from adjacent development, opportunity to use existing development and avoid environmentally sensitive areas, and proximity to planned future development. 77 The conceptual site option was in close proximity to the customer s future development. The selected Yeo 2015S Substation site aligns with industrial stakeholders future plans, was located on suitable ground conditions, and aligns with AESRD s policies and guidelines. This location is selected as the proposed Yeo 2015S Substation site. 78 The Yeo 2015S Substation site is preferred for the following reasons: It is compatible and integrated with surrounding current and planned developments; It reduces the overall impact of the proposed facilities on all stakeholders and the surrounding environment; ATCO Electric will not have to construct new access to the substation; The amount of new clearing for temporary construction laydown area is less than other areas; It avoids environmentally sensitive areas; It allows for future expansion; and It reduces length and footprint of connections to the customer s future development. 79 Ultimately, one conceptual route option was selected [Drawing-A-08, Attachment 6] based on key routing criteria, favourable metrics, and early government and industry feedback. 3.6 PROPOSED ROUTE AND SITE 80 The selected substation site and transmission line route were presented to stakeholders, inclusive of oil and gas developers, agencies, First Nations, interested parties, and the general public [Participant Involvement Program, Attachment 3]. The selected substation site and route are shown on the Proposed Route Mosaic [Drawing AO-08, Attachment 6] Yeo 2015S Substation Site Selection 81 ATCO Electric identified the selected Yeo 2015S Substation site, as seen in the notification package (July 2014) in Attachment 11, as having favourable ground Yeo Substation Project Page 21 Attachment 1 Application Text

30 Application to the Alberta Utilities Commission October 2014 conditions, reducing fragmentation of habitat and landscape at the site and being in close proximity to the customer s future development. The Proposed Site Plan is shown in Attachment 5 [Drawing AO-06]. 82 Proximity of the selected substation site to the existing Birchwood Creek 960S Substation and the direct adjacency to the customer s MacKay Terminal reduces project impacts. The adjacent sites will be used for temporary construction purposes as well as area for anticipated future distribution line routing. This is consistent with the LARP objectives in reducing land-use impacts Proposed Route for 9L144 and 9L57 83 The Proposed Route for transmission line 9L144 integrates existing land-use development as it utilizes the existing 9L57 right-of-way. A portion of transmission line 9L57 will be re-routed directly adjacent and parallel to the 9L144 right-of-way, which will reduce the total amount of land disturbed by integrating tree-free zones. This arrangement avoids two unnecessary and higher risk line crossings. 84 The 9L57 and 9L144 proposed alignment does route through caribou habitat and environmentally significant areas. However, the current proposed alignment allows for minimal tree clearing, integration with existing disturbances, reduction in safety hazards, and increased electrical reliability (see Table 8). Alternative routing would increase the risk to the public, increase project costs and increase impacts to the environment. 85 ATCO Electric publicly notified with this transmission line alignment, as seen in the notification package (July 2014) in Attachment 11, to understand the constraints and benefits associated with the selected location through consultation with the public, industrial stakeholders, first nation communities and AESRD. 86 Ultimately, this route was chosen based on key routing criteria, favourable metrics and early government and industry feedback. This was the basis for formal consultations with government agencies, local industry, First Nations, trappers, and the public. Yeo Substation Project Page 22 Attachment 1 Application Text

32 Application to the Alberta Utilities Commission October EVALUATION AND SELECTION OF PROPOSED ROUTE AND SITE 87 Based on stakeholder consultation and analysis of routing metrics, ATCO Electric has selected the Proposed Route as the most preferred routing option Proposed Yeo 2015S Substation Site 88 The site for Yeo 2015S Substation is favoured by ATCO Electric due to: Integration with current developments; Proximity to the customer s future development; Low environmental impacts overall; and No stakeholder or agency concerns with the proposed locations. 89 Based on these factors, ATCO Electric chose the site as shown in Attachment 5 (Dwg AO-06) and Attachment 6 (Dwg AO-08) as the selected Yeo 2015S Substation site Proposed Route for Transmission Line 9L The Proposed Route for transmission line 9L144 was selected because it: Minimizes disturbances to natural systems in the Study Area; Requires no new access; Has low environmental impacts overall; No transmission line crossings; Has no objections from stakeholders and agencies consulted; and Minimizes transmission line length and cost. 91 The proposed 240-kV transmission line 9L144 from the Birchwood Creek 960S to the proposed Yeo 2015S Substation Substation is described in detail in Table 9. Detailed route information is shown on the Proposed Route Mosaic [Drawing AO- 06, Attachment 6], and on the Cross Sections [Drawing A-09a and b, Attachment 7].

34 Application to the Alberta Utilities Commission October ENVIRONMENTAL AND ELECTRICAL EFFECTS 4.1 ENVIRONMENTAL EFFECTS 92 ATCO Electric will construct and maintain the proposed transmission facilities adhering to AESRD s RR11-0, Environmental Protection Guidelines for Transmission Lines, and in accordance with the terms and conditions of the rightof-way agreements and easements. Measures to reduce the Project s environmental impacts along with general reclamation and long term right-of-way management practices are described in the Environmental Evaluation [Attachment 2] and the Environmental Protection Plan [Attachment 9] Stormwater Management In designing the Yeo 2015S Substation site, the primary consideration with regard to storm water runoff will be to keep the pad free from standing water and allow storm water to drain naturally from the substation area towards adjacent low-lying areas. An increase in post-runoff quantity due to building the substation pad is not anticipated due to the insignificant difference between the runoff coefficient of pad material (un-compacted insulation gravel) and the existing ground material. The existing ground slope surrounding the site is much greater than the design slope of the substation pad, which will minimize surficial runoff quantities. 94 Spill containment, reporting, and clean-up protocols which are standard at all ATCO Electric facilities will reduce incidences of substance contact with stormwater. 4.2 NOISE EFFECTS 95 Any significant noise or traffic is generally limited to the construction period, when larger trucks and equipment are required for moving and construction. 96 A Noise Impact Assessment (NIA) was conducted in accordance with the current AC Rule 012: Noise Control. The Noise Impact Assessment Summary orm is included in Attachment 12. The results indicate that the proposed facility does not exceed permissible sound levels. The nearest noise receptor (work camp) from the substation is approximately 2500 m away. 4.3 HISTORICAL RESOURCES 97 ATCO Electric recognizes the potential of encountering sites with historical resource value along the proposed right-of-way. Through consultation with Alberta Culture (AC) it has been determined that a Historical Resources Impact Yeo Substation Project Page 26 Attachment 1 Application Text

35 Application to the Alberta Utilities Commission October 2014 Assessment (HRIA) is not required. Historical Resource Act clearance was applied for in August In October 2014, ATCO Electric received Historical Resources Act Clearance. 98 ATCO Electric anticipates that the potential of encountering any sites with historical resource value is low. If any sites with historic resource value are discovered during construction, all work in proximity to any such sites will be suspended until permission to continue is granted by AC. ATCO Electric anticipates that any historical resources identified within or near the proposed right-of-way can be avoided or mitigated. Avoidance strategies may include adjusting structure and access road locations, flagging, or installing a temporary fencing at the sites. Mitigation strategies may include restricting traffic, use of laydown mats or other temporary protective materials, or AC approved scientific excavation and recording. 4.4 ELECTRICAL EFFECTS 99 High voltage transmission facilities (alternating current) have electromagnetic fields (EM) or invisible lines of force associated with the electric fields (the result of the strength or voltageof the electric charge) and magnetic fields (the result of the motion or currentof the charge). EM is present everywhere that electricity is used. Considerable research has been conducted to assess the potential interference or noise created by these fields and the effects that they may have on commonly used equipment such as radio, television, lobal Positioning Satellite (PS), etc. enerally, most modern equipment has been designed so that it is largely unaffected by EM interference. Electric fields may also induce a voltage in metal objects that are located nearby; the most common of these are metal fences and buildings, telephone lines, and pipelines. Below is a summary of the common issues and current mitigation Electric and Magnetic Fields (EMF) Human Exposure 100 Alternating Current (AC) transmission lines are a source of extremely lowfrequency (EL) electric and magnetic fields. Both of these electric (kvm) and magnetic (m) fields are at their highest levels directly under the transmission line, decreasing dramatically in strength with distance from the source. Electrical ields (kvm) are also blocked by objects (trees, buildings, etc.), which greatly reduces field strength. ith increased distance from the right-of-way, the EL EM that is associated with AC transmission lines is similar in effect to the natural low-level electric and magnetic fields that we are exposed to in our daily lives (e.g., from appliances, the wiring in homes). 101 Research on EM has been monitored by many health authorities including Health Canada (HC) and the orld Health Organization ( HO). These Yeo Substation Project Page 27 Attachment 1 Application Text

36 Application to the Alberta Utilities Commission October 2014 authorities have evaluated a variety of studies on EM and health. To date, the weight of scientific evidence does not support a cause and effect relationship between general health symptoms and exposure to EM. Currently, there are no Canadian government standards for exposure to EM at EL. Some international agencies have proposed recommended guidelines for exposure. 102 hile landowners and occupants occasionally raise questions regarding the potential for health effects from EM, ATCO Electrics review of available information on biological research and epidemiological studies indicates that the scientific evidence is not strong enough to conclude that exposures to EM at EL cause health problems. ATCO Electric has adopted the conclusions and recommendations of HC, HO, and the International Commission on Non- Ionizing Radiation Protection (ICNIRP) with respect to the EM associated with both Alternating Current and Direct Current transmission lines. ATCO Electric is also committed to monitoring EM research and sharing this information with customers, employees, government officials, or any other interested parties. 10 ICNIRP updated their exposure guidelines in September or magnetic field exposure, ICNIRP recommends a public exposure guideline of 2,000 m, and an occupational (worker) exposure of 10,000 m. or electric field strength, ICNIRP recommends a public exposure guideline of 4.2 kvm and an occupational (worker) exposure of 8. kvm. The expected EM levels for the proposed transmission line will be well below the public exposure guidelines at the edge of the right-of-way. 104 ATCO Electric builds and operates all of its electric facilities to industry and safety standards and strives to route new facilities away from residences and densely populated areas wherever possible. The nearest residence (industrial work camp) to the transmission facilities proposed in this application is approximately 2.5 km north Electric and Magnetic Fields (EMF) Animal Exposure 105 Research has also been conducted on the possible effects of EM on various wild and domesticated animals. A number of universities and national agencies both in the S and Canada have carried out studies on cattle, pigs, sheep, and horses to determine whether EM produced by high-voltage AC transmission lines has any effect on the health, productivity, reproduction, or behaviour of livestock. A review of this research indicates that exposure to EM from AC transmission lines is not a demonstrated cause of any adverse health effects for these animals. 106 Research into the possible effects on smaller animals, including bees and some birds that detect electromagnetic fields for navigational purposes, reveals similar Yeo Substation Project Page 28 Attachment 1 Application Text

37 Application to the Alberta Utilities Commission October 2014 results. Evaluation of these findings does not support the indication of any adverse effects from EM exposure. There has been no indication that EM from transmission right-of-ways interfere with the homing behaviour of birds or bees. Most often, where bee hives are located under AC lines, the bees appear to receive small but frequent nuisance shocks in hives from currents induced by the lines. However, this is primarily associated with domesticated bee hives, and mitigation can include shielding the hives or relocating the hives away from the lines (outside of the right-of-way). 107 As with human studies, government and research organizations continue to monitor and assess new and current findings of animal research to ensure the most up to date information on EM is being considered Radio and Television Interference 108 Corona is defined as the electrical breakdown of air ions around the conductors (ionization) as a result of high or non-uniform electric fields. Corona may create some electromagnetic noiseat or near the same frequency as a radio signal. Potential for this noise to interfere with radio reception is dependent upon the frequency and strength of the signal, as weaker signals have greater potential to be affected. AM radio operates at a lower frequency than M, and the greatest potential for AM radio interference would be directly below the transmission line, decreasing rapidly as you move away from the line. The higher frequency of M radio signals typically does not pick up any interference from transmission lines. Two-way radios may be subject to low levels of interference, as a result of obstructed line of sight between the transmitter and receiver associated with buildings, geographic features or towers. This situation can be easily mitigated by moving the transmitter to a nearby location with a clean line of sight. 109 The potential for television interference (TVI) is much less than radio interference and is generally not a concern. If a transmission structure is located between the TV source signal and the receiver, it is possible to see evidence of interference (shadowing). As transmission structures have large distances between each structure, this potential interference can easily be mitigated through structure placement. Digital signals have a greater tolerance to interference sources. Satellite TV signals are typically free of TVI as ATCO Electric routes transmission lines away from residences wherever possible and therefore no transmission structures should be located close enough to affect the line of sight of the satellite receiver. 110 The limits for Radio Interference (RI) are specified in Canadian standard CAN- C The maximum field intensity of radio noise produced by the proposed Yeo Substation Project Page 29 Attachment 1 Application Text

38 Application to the Alberta Utilities Commission October 2014 transmission line (in fair weather, at 15 m from the outer phase), will not exceed the RI limit of 5 db above 1uVm for 200 to 00-kV systems. 111 Transmission power lines do not generally affect lobal Positioning Systems (PS). PS units receive their data using high frequency communication with multiple satellites. As the unit moves, the unit is constantly dropping and picking up different satellites. In rare occasions a large object like a transmission structure could potentially block the signal if it is in direct line with the receiver and the satellite. This is extremely rare and is usually temporary as the satellites are constantly moving, and the PS unit may also be moving. Even in this rare situation, PS units using multiple satellites should still function as normal. Poor satellite connection can be caused by many things (no visible satellites in the area, outage at satellite base station, etc.). 112 The transmission facilities will be constructed and maintained in such a manner as to keep electric interference levels within limits acceptable to Industry Canada, the federal government department that regulates communications. In general, interference has not been a problem for ATCO Electric s facilities, but, in the event that problems are reported, ATCO Electric will work with the affected parties to identify the sources of the interference and to mitigate any interference that may be caused by the proposed facilities Telephone Facilities nder certain conditions, power transmission facilities can induce both electrical noise and hazardous voltages on telephone lines. ATCO Electric will work with TELS before and after construction to identify and mitigate adverse impacts. 114 Cellular phone interference from transmission lines is unlikely, as cellular signals operate at higher frequencies than those in which corona interference is usually prevalent. Similar to television and radio signals, cellular interference can result from an obstructed line-of-site with the signal receiver. Cellular phone service signals are multidirectional so in the unlikely case of this interference, the effect would be minimal and most often experienced temporarily in close proximity to the structure Metal Fences, Buildings and Structures 115 Transmission facilities can cause induced current and voltage in nearby metallic objects, especially those which parallel the transmission line. The potential for induced voltage is primarily related to the strength of the electric or magnetic field and the distance the object parallels the line. These shocks are typically more of a nuisance level, such as the static electricity shock received after walking across a carpet. here necessary, metal fences, buildings, and structures will be Yeo Substation Project Page 30 Attachment 1 Application Text

Other mitigation options are available where electric fences exist, in order to keep the possibility of induced voltages to an acceptable level. Minimum clearance required between all transmission facilities and buildings will be in accordance with the Alberta Safety Codes Act and regulations Oil and Natural Gas Well Heads 116 ATCO Electric will meet or exceed setbacks for active wells and their associated developments as stated in Section 10 Overhead Systems in the Alberta Electrical Utility Code and abandoned wells as stated in the Alberta Energy Regulator s Directive 079: Surface Development in Proximity to Abandoned Wells. These setbacks will be from the active well bore and its associated developments or the abandoned well bore to the edge of ATCO Electric s principal right-of-way, in order to accommodate maximum conductor swing. ell bores that are drilled subsequent to the application date but prior to securing land rights will be appropriately accommodated, along with their associated developments, in the design of the Project Pipelines 117 The Alberta Safety Codes Act and the AER s Pipeline Act both have regulations to which ATCO Electric and the pipeline operators must adhere. ATCO Electric, in conjunction with pipeline operators, will continue to meet the regulated standards so that both transmission and pipeline facilities can be operated safely. 118 Two industry stakeholders requested corrosion studies. ATCO Electric will work with the stakeholders to complete this request. 4.5 LANDSCAPE AND AESTHETICS 119 Visual impacts are considered during the routing and siting of facilities. However, some of the issues concerning these impacts are that they are difficult to quantify, very subjective and vary between stakeholders. here practical, ATCO Electric has attempted to limit potential visual impacts by avoiding close proximity to protected areas. 120 No scenic viewpoints have been identified through agency or stakeholder consultation.

45 Application to the Alberta Utilities Commission October 2014 ENVIRONMENTAL EVALUATION 1.0 INTRODUCTION 1 ATCO Electric Ltd. (ATCO Electric) proposes to construct a new 240 kilovolt (kv) substation (Yeo 2015S Substation) and 1.5 km of new single-circuit 240 kv transmission line (9L144) connecting the proposed Yeo 2015S Substation to the approved Birchwood 960S Substation [Figure 1 and Route Mosaic, Attachment 6]. As well, alterations to the existing 9L57 transmission line will be conducted ( Line Swap ). These facilities are described in the application text [Attachment 1]. These facilities are considered at the request of Grand Rapids Pipeline Ltd. (the Customer). 2 This document describes the project environment, the potential impacts of the project, and the measures proposed to mitigate these impacts as required by AUC Rule 007. The Environmental Evaluation described in this document follows Canadian best practices for the assessment of project impacts and residual significance. The evaluation was based on the information available at the time of writing and may change as additional information is acquired. 3 Should environmental conditions change at any point in the project, environmental professionals will reassess the potential impacts and apply the appropriate mitigation measures. 1.1 PROJECT SETTING 4 The project is located within the Boreal Forest Natural Region (Natural Regions Committee 2006). The nearest weather station is Fort McMurray A which is located at the Fort McMurray Airport. The region experiences short cool summers and long cold winters, with an annual average temperature of 1.0 C with a July high of 17.1 C and a January low of C (Environment Canada 2014). Total average precipitation is millimetres (mm) of which mm are rainfall; rainfall is maximal in July at 80.7 mm (Environment Canada 2014). 5 The project site is located within the Central Mixedwood Subregion of the Boreal Forest Natural Region. The Central Mixedwood Subregion consists of upland aspen, mixedwood, and white spruce forests with large areas of treed fens and lesser components of jack pine. Gray Luvisolic soils with medium to fine textures dominate upland sites, with Brunisols present in conjunction with sandy soils, and Organic soils on poorly drained fens and other lowlands. Topography consists of gently undulating plains with some hummocky uplands. Wetlands are often extensive and consist mostly of black spruce fens and bogs on Organic soil (Natural Regions Committee 2006). 6 There are no major drainages within the Project Area. The Route does not cross any streams, creeks, or rivers. Yeo Substation Project Page 1 Attachment 2 Environmental Evaluation

46 Application to the Alberta Utilities Commission October No minor drainages and creeks will be crossed by the proposed transmission facility. 1.2 ROUTING AND SITING CRITERIA 8 A desktop assessment of the routing metrics was undertaken to evaluate the transmission line right-of-way described in Attachment 1. A review of existing data was sourced from various agencies using geographic information systems (GS) software. nformation search sources are provided in Section 2.2 below. 9 A route metrics assessment was completed considering potential industrial, environmental, geographic, and social constraints. Metrics related to the Environmental Evaluation are provided in Table REGULATORY GUIDANCE 10 ATCO Electric will undertake project activities while adhering, but not limited, to Alberta Environment s C&R/IL/11-03, Environmental Protection Guidelines for Transmission Lines; Fisheries and Oceans Canada (FO) Self-Assessment Process (Government of Canada 2014); Alberta Environment and Sustainable Resource evelopment (AESR) Code of Practice for Watercourse Crossings (Government of Alberta 2013a); AESR Code of Practice for Pipelines and Telecommunications Lines (Government of Alberta 2013b); AESR Sensitive Species Survey Guidelines (AESR 2013); ATCO Electric s general construction and maintenance environmental standards including the Environmental Protection Plan (EPP); and Terms and conditions of the applicable right-of-way agreements and easements. 11 All activity will be confined to ATCO Electric s acquired dispositions and property agreements.

48 Application to the Alberta Utilities Commission October METHODOLOGY 12 The Environmental Evaluation reviews, summaries, and interprets desktop and field data from the project environment and proposed transmission facilities, makes recommendations in regards to mitigation and monitoring, and assesses the significance of environmental impacts of transmission facilities as required by AUC Rule 007. The adversity of environmental impacts will be evaluated by major valued environmental components (VECs). A valued environmental component is defined by its ecological, cultural, social, or economic value and its environmental function, characteristics, or elements. A list of VECs used in this Environmental Evaluation is provided below and is based on AUC Rule 007 Archaeological and historical resources; esignated areas; Soils and terrain; Surface water and wetlands; Vegetation; and, Wildlife. 13 The Environmental Evaluation will provide the following information dentify the environmental components and effects to be considered (Section 2.0); Set appropriate geographical and temporal boundaries for the Environmental Evaluation (Section 2.1); Summarie the status of the current environment and assess the environmental effects of the project (Section 1.1, Section 3.0 through 8.0); dentify mitigation and monitoring measures for the specified environmental effects (Section 3.0 through 8.0); and etermine the residual significance of adverse impacts based on a standardied methodology which considers value, extent, duration, frequency, reversibility, and magnitude of the impacts (Section 3.0 through 8.0). Yeo Substation Project Page 4 Attachment 2 Environmental Evaluation

49 Application to the Alberta Utilities Commission October PROJECT BOUNDARIES 14 The project boundaries are displayed in Figure 1. The description of each boundary is provided in the subsequent sections. Project boundaries defined below form the spatial basis for the Environmental Evaluation for the purposes of assessing the significance of the potential environmental impacts Project Footprint 15 Potential impacts from the project that are not predicted to extend beyond the substation property, right-of-way, and a conservative estimate of vegetation control easement (VCE) are considered to be part of the project footprint. For the purposes of analysis, the VCE is assumed to be 30 m unless otherwise stated. The total area of the project footprint is 9.7 ha, which is the combined area of the right-of-way, VCE, and substation footprint (Table 1) Project Area 16 The Project Area for the Project is considered to be 1000 m from the centerline of the right-of-way. The 1000 m one set for Project Area would encompass any potential setback distance, restricted activity period, noise receptor, waterway, or any VEC which the project may impact directly or indirectly. The Project Area is ha (Table 1). 2.2 DATA SOURCES 17 A desktop review of the Project Area was conducted using geographic information system (GS) software and existing environmental data sets. The following sources of information were used to provide the basis of the desktop assessment Alberta Conservation nformation Management System (ACMS); Alberta Culture (AC); AESR Wildlife Sensitivity Maps ata Sets; Aquatic Environmentally Significant Areas (AESA); Committee on the Status of Endangered Wildlife in Canada (COSEWC); Endangered Species Conservation Committee (ESCC); Environmentally Significant Areas (ESA); Fisheries and Wildlife Management nformation System (FWMS); General Status of the Alberta Wild Species 2010 (GSAWS); mportant Bird Areas (BA); Parks and Protected Areas; Yeo Substation Project Page 5 Attachment 2 Environmental Evaluation

50 Application to the Alberta Utilities Commission October 2014 Protective Notations (PNT); Provincial Graing Reserves (PGR); and 18 ATCO Electric has completed surveys with the assistance of subject matter experts in accordance with AESR 2013 Survey Guidelines (AESR 2013) or other guidelines as appropriate. Findings from the surveys will be shared with AESR. Surveys completed were rare plant surveys; boreal raptors; breeding birds; amphibian (auditory); weeds; and a wetland evaluation. The results of these surveys are discussed in sections 5.2, 7.2, and 8.2 below. 2.3 GENERAL MITIGATION MEASURES 19 ATCO Electric has developed an Environmental Protection Plan (EPP) for its construction activities (Attachment 9). The EPP provides project managers and construction team leads with the assistance of environmental experts set of tools and mitigation measures for specific environmental components. The tools reduce the severity and duration of project impacts to the environment. 20 ATCO Electric will strive to reduce the environmental footprint of the project including the type, extent, duration, and severity of environmental impacts. Where avoidance of environmental impacts are not possible, the tools in the EPP will be employed to reduce the extent and severity of the impacts or in the unlikely case, compensate for the lost, damaged, or destroyed VEC. Specific mitigation measures identified to reduce impacts are provided in Sections 3.0 through EVALUATION OF SIGNIFICANCE 21 AUC Rule 007 requires proponents to identify the residual significance of environmental impacts of proposed transmission projects. ATCO Electric developed assessment methodology based on the guiding documents for evaluating significance produced by the Canadian Environmental Assessment Agency (CEAA) (Government of Canada 1994; egmann et al 1999). Though this project is not under federal jurisdiction, and an EA is not required under the Alberta Environmental Protection and Enhancement Act or the Canadian Environmental Assessment Act, 2012, the guidance from CEAA represents a reasonable best practice for evaluating residual significance of project impacts in Canada. 22 The residual significance of impacts is assessed on the geographic extent, duration, frequency, reversibility, and magnitude of the impact. The impacts are assessed after the assumed application of the proposed mitigation measures in this EE and the EPP associated with the project, along with any requirements from regulators. The rating criteria are outlined in Table 2. The significance criteria are provided in Table 3. Yeo Substation Project Page 6 Attachment 2 Environmental Evaluation

Impacts which may extend beyond 10,000 m from the project or are likely to have effects which cross regional, provincial, interprovincial, national, or international scales. Not applicable to this project. Impacts do not last beyond the construction stage of the project Projects may last up to the typical lifetime of the project or extend beyond the construction phase; however, they are recoverable under assisted or natural conditions Impacts extend beyond the construction phase or result in a permanent loss of habitat quantity, quality, biodiversity, productive capacity, or historical resources Effect occurs once or less than once per year Effect occurs at least once per year Effect occurs at least once per week Construction of the project and removal of effect source will allow natural processes to recover the site to its pre-construction condition Achieving pre-construction condition will require intervention using reclamation and remediation best practices and techniques Achieving pre-construction condition is not possible within a human lifetime Impact makes no measurable change to the VEC Impact may result in some measurable change to the VEC but no measurable loss in function or value Impact will result in some measurable change to the VEC with measurable loss in function or value which can be mitigated Impact will result in measurable change to the VEC with measurable or permanent loss in function or value which cannot be mitigated Yeo Substation Project Page 7 Attachment 2 Environmental Evaluation

53 Application to the Alberta Utilities Commission October ARCHAEOLOGICAL AND HISTORICAL RESOURCES 3.1 DESKTOP STUDY 23 A desktop analysis of existing Government of Alberta data sources indicates that no historical resource values (HRVs) are located within the Project Area. 3.2 FIELD SURVEY 24 ATCO Electric applied for a Historical Resources Act clearance from AC in July Clearance, or requirements to conduct a Historical Resource Impact Assessment, have not yet been received. No field survey data was collected for Archaeological and Historical Resources at this time. 3.3 EFFECTS ANALYSIS AND MITIGATION 25 Project activities including brushing, grubbing, access, and construction may impact archaeological and historical resources. Impacts would be confined directly to the Project Footprint. There are no known HRV resources which could be impacted by the Project activities according to existing data; therefore, there is a low likelihood of encountering Historical Resources. The project will require additional soil or brushing disturbances. The mitigation measures include suspending work and notifying AC if archaeological or historical sites are discovered, adjusting structure and access road locations, restricting traffic, use of temporary protective coverings, using AC approved scientific excavation and recording methods, delaying work until permission to proceed is granted by AC, and staking or flagging known resources. The impact would be limited to the Project Footprint, not last more than one year, would be rare, be non-reversible, and negligible in magnitude. Therefore this impact is not likely to be significant. Yeo Substation Project Page 9 Attachment 2 Environmental Evaluation

54 Application to the Alberta Utilities Commission October DESIGNATED AREAS 4.1 DESKTOP STUDY Environmentally ignificant Areas (EA) (Environmental Constraints ap, Figure 1) have been identified within the Project Area with a total area of approximately ha (. ) of the Project Area (Table 1). The Project Footprint does overlap with the EA with a total area of approximately.2 ha (3. ) in the Project Footprint (Table 1). This designated area type may contain lands important to maintaining biological diversity, soil, water, wildlife, or other values, or represent important habitats for valued species, species of concern, or rare communities (FIERA 200). EAs are listed with potential to contain seven () criteria 1. Elements of conservation concern; 2. Rare or unique landforms; 3. Habitat for focal species; 4. Important wildlife habitat; 5. Riparian areas with subcategories;. arge natural areas; and. ites of recognied significance. One EA was identified within the Project Area, EA 3, which contains Criteria 1 Contains Elements of Conservation Concern; Criteria 2 Rare or nique andforms; Criteria 3 Habitat for Focal pecies; Criteria 5b Contains Intact Riparian Areas; and Criteria arge Natural Areas. This EA is rated as Provincially ignificant. An Aquatic Environmentally ignificant Area (AEA) (Environmental Constraints ap, Figure 1) have been identified within Project Area (5. ha or.5 ); however, the AEA does not overlap with the Project Footprint (Table 1). AEAs are the aquatic counterpart to EAs and may contain lands which are important for maintaining biological diversity, water, fish species, or species of concern (FIERA 2010). AEAs are listed with potential in seven () criteria 1. Presence of aquatic focal species, groups, or their habitat; 2. Presence of species of conservation concern; 3. Presence of rare or unique aquatic ecosystems; 4. ey areas that contribute to water quality; 5. ey areas of biological connectivity;. ey areas of intact complexity andor biodiversity; and Yeo Substation Project Page 10 Attachment 2 Environmental Evaluation

55 Application to the Alberta Utilities Commission October ey areas that contribute to water quantity. The Project Footprint is not located in an AEA. The Project Area overlaps with one (1) AEA AEA 1550 which contain criteria 1, 2, 3, 4, 5 and as explained above. 30 No other designated areas, such as wildland parks, provincial parks, wilderness parks, or natural areas were identified within the Project Footprint or Project Area. No ey ildlife iodiversity ones are located within the Project Footprint or Project Area. No PNTs were identified within the Project Footprint or Project Area (Environmental Constraints ap, Figure 1). 4.2 FIELD STUDY 31 No field studies were conducted for esignated Areas and no field surveys were required by AER. 32 A and se survey was conducted on behalf of ATCO Electric by CH2 Hill to determine the land use of the preferred route (CH2 Hill 2014d). The survey determined that the majority of lands crossed by the Project components consisted of wetlands, and forested areas, while shorter transmission line length and paralleling existing disturbances minimie the environmental impacts (CH2 Hill 2014d). 4.3 EFFECTS ANALYSIS AND MITIGATION 33 Project activities including access, maintenance, construction, and operation may impact AEAs within the Project Area. Impacts may expand up to the Project Area, and would primarily occur during construction. Impacts may include a decline in the AEA value or function. itigation measures would include conducting work activities in dry or froen ground conditions or avoiding work in the AEA. Impacts to AEAs may extend into the Project Area, would be rare, last less than one year, and would be naturally reversible and negligible in magnitude. Therefore the impact is not likely to be significant. 34 Project activities including access, maintenance, construction, and operation may impact the EA. Impacts may expand up to the Project Area, and would primarily occur during construction. Impacts may include a decline in the EA value or function. itigation measures would include conducting work activities in dry or froen ground conditions, minimiing the requirements for additional clearings, and following recommended setbacks or timing restrictions for elements of conservation concern. Impacts to EAs may extend into the Project Area, would be rare, last less than one year, and would be naturally reversible and negligible in magnitude. Therefore the impact is not likely to be significant. Yeo Substation Project Page 11 Attachment 2 Environmental Evaluation

56 Application to the Alberta Utilities Commission October SURFACE WATER AND WETLANDS 5.1 DESKTOP STUDY 35 There are no watercourses crossed by the Project. No lakes are traversed by the proposed transmission line 144 or existing 5, and there are no lakes located within 100 m of the proposed eo ubstation. Therefore the Project will not require the installation of temporary or permanent crossings, and fording will not be required ( etland Constraints ap, Figure 2). 3 3 The Project Area is located within the Green one of Alberta. Provincial etland Inventory ata was not available for the Project Area due to an incomplete database. CH2 Hill, on behalf of ATCO Electric, completed a separate esktop tudy of wetlands within the project area using aerial imagery evaluation (CH2 Hill 2014g). The wetlands identified were classified as hrubby Fen, Treed Fen, and Treed og under the Canadian etland Classification ystem (C C). Approximately 0.1 ha (12 ) of transmission footprint is wetland, and approximately 3.0 ha ( ) of eo ubstation is wetland (CH2 Hill 2014g). No mineral or open water wetlands requiring ater Act approval or Code of Practice (COP) notification were identified. 5.2 FIELD SURVEYS 3 3 urveys are not required as urface aters such as lakes and watercourses are not located within the project footprint; therefore, field surveys were not conducted for urface aters. Field surveys were conducted for etlands in order to verify the desktop study, provide specific recommendation measures, and identify any regulatory requirements. CH2 Hill, on behalf of ATCO Electric, completed a field wetland evaluation from August th to August th, The field survey indicated that slightly less wetland area would be impacted compared to the desktop survey 0.5 ha for the proposed transmission line 144; and 3.0 ha for the proposed eo ubstation (CH2 Hill 2014h). All wetlands were identified as bogs and fens, and no mineral or open water wetlands were identified (CH2 Hill 2014h) ( etland Constraints ap, Figure 2). 5.3 EFFECTS ANALYSIS AND MITIGATION 40 urface waters may be impacted by runoff of accidental spills and releases of deleterious material, and sediments. Impacts may result in increased sedimentation, erosion, or deposition, or loss of habitat. itigating impacts to surface waters include not operating machinery within watercourses without appropriate dry or froen conditions, constructing crossings which comply with Yeo Substation Project Page 12 Attachment 2 Environmental Evaluation

57 Application to the Alberta Utilities Commission October 2014 the Code of Practice for Watercourse Crossings, complying with the restricted activity periods, installing silt fencing as warranted by ground conditions, minimiing the clearing of riparian vegetation, following the FO elf- Assessment Process (Fisheries and Oceans Canada 2014), withdrawing water only under approval from AER, and restricting refueling and maintenance activities 100 m or more from waterbodies. Impacts would be restricted to the Project Footprint up to the tudy Area, would be rare, would not last longer than one year, and would be naturally reversible and minor in magnitude. Therefore the impact is not likely to be significant. 41 etlands may be impacted by crossing of machines and equipment, accidental spills and releases of deleterious material, access, maintenance, construction, and operation. Impacts may include wetland loss, habitat loss, destruction of species, conversion of vegetation cover, modified surface drainage patterns, and soil damage or loss. itigating impacts to wetlands includeoperating in froen conditions where feasible; freeze-in wetlands with additional clean water and snow fill; refueling 100 m or more from a wetland on an impervious surface with secondary containment; minimiing brushing and vegetation removal within the wetland; minimiing construction traffic in wetlands; ensuring machinery arrive on-site free of mud; vegetation debris and fluid leaks; install berms, crossditches, or silt fences between wetlands and upland areas as appropriate; spreading mulch to a depth of no more than 5 cm along construction areas; allowing natural regrowth of wetland vegetation; using low ground pressure (GP) equipment and swamp mats as appropriate; maintaining an onsite spill kit; and, obtaining Water Act approvals as necessary. Impacts would be restricted to the Project Footprint, would be rare, last less than one (1) to one hundred (100) years, and would be naturally reversible to reversible with intervention and negligible to moderate in magnitude. Therefore the impact is not likely to be significant. Yeo Substation Project Page 13 Attachment 2 Environmental Evaluation

58 Application to the Alberta Utilities Commission October SOIL AND TERRAIN 6.1 DESKTOP STUDY 42 oils support overlying vegetation and natural processes. Impacts to soils are mandated to be analyed in the AC Rule 007. As described in ection 1.1, the predominant soils of this subregion are uvisols, Gleysols, and Organic soils under ixedwood stands. 43 Canadian ands Inventory (CI) soil classification data was available to determine some soil characteristics or potential project impacts (oil Constraints ap, Figure 3). The project is located within oil Correlation Area 20 which is associated with the Central ixedwood ubregion for Central and Northern Alberta (Pedocan and Evaluation td. 13). The following soil classes were present on the right-of-way Class 5 lands having severe limitations to the growth of commercial forests; Class lands having severe limitations to the growth of commercial forests; and, Class no capacity for arable agriculture or permanent pasture (oil Constraints ap, Figure 3). 44 esktop information on ind and ater Erosion risks were not available for the project area. ATCO Electric does intend to remove covering vegetation from the soil, or strip soil, in order to complete the work on the proposed eo ubstation; however, only minor or temporary soil displacement will be required for the Rightof- ay. The work will be completed in froen conditions which will afford greater soil protection and reduce risks of both wind and water erosion. 6.2 FIELD SURVEYS 45 No soil surveys are planned for this project. Geotechnical surveys may be completed to finalied civil engineering design information garnered from these investigations may be used to modify soil impact mitigation measures. 6.3 EFFECTS ANALYSIS AND MITIGATION 4 oils may be impacted by operation, maintenance, and construction activities. Impacts may include loss of soil productivity, loss of topsoil, soil compaction, or soil contamination. easures for mitigating impacts to soils includeconstructing on dry or froen ground; using low ground pressure equipment; reducing vegetation clearing; ensuring sufficient coverage of ice or snow for access roads and travel lanes when possible; following the methods for mitigating deleterious substances outlined in ection 5.3 above; establishing an Erosion and iltation Plan (ATCO Electric 2014); controlling dust with an appropriate dust suppressant where necessary; having a etthawed oil Contingency Plan (ATCO Electric 2014); using geotextiles, substrates, and rig mats; or, delaying construction until conditions improve. Impacts would be restricted to the Project Footprint, may last Yeo Substation Project Page 14 Attachment 2 Environmental Evaluation

60 Application to the Alberta Utilities Commission October VEGETATION 7.1 DESKTOP STUDY 4 4 Typical vegetation in the Central ixedwood region includes mixedwood, spruce, and aspen stands with understories of low bush cranberry, prickly rose, green alder, bunchberry, wild sarsaparilla, and hairy wild rye. This project is located in a mix of wetland and forested land cover. Vegetation in the Project Area is primarily treed bogs and fens, along with dense coniferous forest. No sensitive vegetation communities or plant species were identified in an Alberta Conservation Information anagement ystem (ACI) search of the Project Area (ACI 2013). 7.2 FIELD STUDY 50 CH2 Hill, on behalf of ATCO Electric, conducted a rare plants survey and weeds survey August th to August th, 2014 (CH2 Hill 2014e, 2014f). The rare plants survey was conducted in accordance with the Alberta Native Plant Council Guidelines for Rare Plant Surveys in Alberta (Alberta Native Plant Council 2012). 51 COE IC or ARA listed species were not observed during the survey (CH2 Hill 2014e). No species with designations under the Alberta Wildlife Act were observed (CH2 Hill 2014e). One ACI listed rare plant species was observed within the Project Footprint in two subpopulations: Bog adder s-mouth (Malaxis paludosa) is a perennial orchid ranked 1 in Alberta (CH2 Hill 2014e). An 1 ranking indicates a species is Critically Imperiled, and at high risk of extirpation from the province due to restricted range, limited populations or occurrences, steep declines, or other severe threats or factors. 52 No Prohibited Noxious eeds were observed during the weed survey (CH2 Hill 2014f). One species of Noxious eed, perennial sow thistle, was observed in very low densities. Two populations of perennial sow-thistle were located on the existing transmission line right-of-way (E ), and within an adjacent industrial clearing (NE ) (CH2 Hill 2014f). No other listed, non-native species were observed. Other non-listed, non-native species observed in low densities were alsike clover, common dandelion, lamb squarters, common plantain, and rough cinquefoil. 7.3 EFFECTS ANALYSIS AND MITIGATION 53 Vegetation may be impacted by brushing, grubbing, construction, operation, and maintenance activities. The rare plant species identified at this time are located in an area of the substation boundary that will not be cleared. Impacts may include a reduction in productive capacity, soil contamination resulting in loss of vegetation, increased potential for forest fires, spread of Noxious eed species, Yeo Substation Project Page 16 Attachment 2 Environmental Evaluation

61 Application to the Alberta Utilities Commission October 2014 or loss of species at risk. itigation measures includeimplementing a Plant pecies of Concern iscovery Contingency Plan (ATCO Electric 2014); marking the location of known species at risk; covering rare plant species with geotextile pads, matting, or snow during froen conditions; complying with the requirements of the Forest and Prairie Protection Act and Regulations; having a Fire Contingency Plan (ATCO Electric 2014) in place; ensuring proper disposal methods of hot or burning material; keeping exhaust and engine systems clean; following the methods for accidental spills and releases in ection 5.3 above; falling timber onto the right of way; reducing vegetation clearing; following the Best Management Practice for Crop Disease Protection and Management of Noxious Weeds (ATCO Electric 2014); cleaning all construction equipment prior to its arrival on site; seeding surface material stockpiles with an approved seed mix; ensuring seed mixes are free of Noxious weed seed; monitoring weed grow on substation site, transmission line right-of-way, and topsoil or strippings piles; and, using equipment which limits surface disturbance. Transplanting plant species at risk may be possible under the direction of AER and a Professional iologist during the growing season prior to construction if construction timelines change. 54 Impacts would be restricted to the Project Footprint, may last years, and would be rare, reversible with intervention, and negligible in magnitude. Therefore the impact is not likely to be significant. Yeo Substation Project Page 17 Attachment 2 Environmental Evaluation

62 Application to the Alberta Utilities Commission October WILDLIFE 8.1 DESKTOP STUDY 55 A search was conducted of the Fish and ildlife Information anagement ystem (F I) by ATCO Electric staff (Government of Alberta 2014). The results of the search did not indicate the presence of any species of management concern. 5 5 The Project Area does not contain any ey ildlife iodiversity ones ( ). The project is located within the oodland Caribou one (Environmental Constraints ap, Figure 1). The project is located within the est Athabasca caribou herd range. No other rare species or species of management concern had identified ranges overlapping with the Project Area. ATCO Electric is preparing a Caribou Protection Plan (CPP) for the project. The CPP will be submitted to AER for approval. 8.2 FIELD STUDY 5 CH2 Hill, on behalf of ATCO Electric and in consultation with AER, completed the following surveys in accordance with AER 2013 ensitive pecies Inventory Guidelines (AER 2013) Amphibians Auditory; oreal and Foothills reeding ongbirds and oodpeckers (reeding irds); and, oreal and Foothills Raptors (Habitat). ue to compressed timelines, it was not possible to complete the surveys during the recommended timing windows. Completing surveys outside of the recommended timing windows may result in some species being unaccounted for; however, these risks may be managed by appropriate implementation of mitigation measures (e.g. winter construction, brushing outside of avian breeding periods, etc.) and the use of additional surveys which were within the timing windows for the area Amphibians Non-Acoustic; and Common Nighthawk. 5 The Amphibian Auditory survey was completed on July 1 th, July 25 th, and August 2 nd, 2014, which is outside of the recommended timing for amphibians in the Project Area. No amphibian species were heard calling during the auditory surveys. Incidental observations of boreal chorus frogs and woods frogs were made during the survey and during other wildlife surveys. Potential, but unconfirmed, breeding habitat exists along the road adjacent to the proposed Yeo Substation Project Page 18 Attachment 2 Environmental Evaluation

63 Application to the Alberta Utilities Commission October transmission line 144 right of way. No western or Canadian toads were observed in the Project Footprint (CH2 Hill 2014a). An additional non-acoustic Amphibian urvey was conducted on July 1 th and August 2 nd, No evidence of amphibian breeding was observed during the surveys. reeding was determined to be more likely to occur at sites greater than 100 m from the proposed disturbance, based on breeding habitat characteristics. Canadian and western toad species were not observed during the survey (CH2 Hill 2014i) The reeding irds survey was completed on July 1 th and July 2 th, 2014, which is outside the recommended timing for conducting surveys in the project area. A total of species were recorded during the survey, with an additional 11 species being recorded incidentally between survey plots or during other wildlife surveys. No active bird nests were observed during the survey (CH2 Hill 2014c). Three (3) species of conservation concern were identified during the survey ellow rail listed as in Alberta as ndetermined under the General tatus of Alberta ild pecies, by COE IC as pecial Concern, and the pecies at Risk Act as pecial Concern chedule 1; andhill Crane listed in Alberta as ensitive under the General tatus of Alberta ild pecies; and Common Nighthawk listed in Alberta as ensitive under the General tatus of Alberta ild pecies, COE IC as Threatened, and the pecies at Risk Act as Threatened chedule 1 (CH2 Hill 2014c; AER 2012; COE IC 2014; Government of Canada 2014). 2 A Common Nighthawk survey was conducted on July 1 th and July 2 th, Two common nighthawk nesting territories were identified within the project area on disturbed areas under the existing transmission facilities, near forest edges around existing substation sites, or mulched logging roads. It is likely that brushing work associated with the Project will create additional common nighthawk habitat (CH2 Hill 2014j). 3 The oreal and Foothills Raptor (Habitat) urvey was completed on July 1 th through the 1 th, and on August 2 nd (CH2 Hill 2014b). This is outside the recommended timing for conducting surveys in the project area. Three (3) species of raptor were observed during the survey Great Gray Owl listed as ensitive in the General tatus of Alberta ild pecies and Not at Risk by COE IC; Red-tailed Hawk listed as ecure in the General tatus of Alberta ild pecies and Not at Risk by COE IC; and harp-shinned Hawk listed as ecure in the General tatus of Alberta ild pecies and Not at Risk by COE IC (CH2 Hill 2014b; AER 2012; COE IC 2014; Government of Canada 2014). All species have a 100 m year round buffer. Only the harpshinned Hawk nest was located within 100 m of the project, with the located estimated to be 52 m from centreline. sing a conservative estimate of 40 m from centerline for combined right-of-way and VCE, it is unlikely that this nest will Yeo Substation Project Page 19 Attachment 2 Environmental Evaluation

64 Application to the Alberta Utilities Commission October 2014 be impacted by construction activities. ATCO Electric is currently in discussions with AER for additional advice and to determine if additional mitigation measures are necessary. 8.3 EFFECTS ANALYSIS AND MITIGATION 4 5 Non-avian wildlife may be impacted by operation, and construction activities. Impacts may include direct mortality, noise or visual disturbance, human-wildlife conflict, loss of species at risk, and increased access for predators. itigation measures includefollowing wildlife timing constraints and activity setback distances; completing and implementing a Caribou Protection Plan; reducing speed limits in high wildlife activity areas and on travel lanes; controlling garbage through proper disposal and waste containment for each working unit; implementing a ildlife pecies of Concern iscovery Contingency Plan (ATCO Electric 2014); implementing a ildlife Encounter Contingency Plan (ATCO Electric 2014); preventing the recreational use of Off-Highway Vehicles on the construction site; flagging locations of hibernation or denning sites; and, providing environmental orientation to construction crews. Impacts would be limited to the Project Area, would be rare, would last less than one year, and would be naturally reversible and negligible in magnitude. Therefore the impact is not likely to be significant. Avian wildlife, particularly large bodied birds with poor maneuverability and eyesight such as waterfowl, may be impacted by operation, and construction activities. Impacts may include direct mortality, loss of habitat, noise or visual disturbance, human-wildlife conflict, loss of species at risk, increased access for predators, and collision or electrocution. itigation measures include conducting nest sweeps if vegetation clearing is required between arch 1 st and August 31 st to limit impacts to breeding birds; following wildlife timing constraints and activity setback distances where possible or seek AER clearance to construct within a setback, reducing speed limits in high wildlife activity areas and on travel lanes; controlling garbage through proper disposal and waste containment for each working unit; implementing a ildlife pecies of Concern iscovery Contingency Plan; implementing a ildlife Encounter Contingency Plan, flagging and buffering nesting sites or breeding areas; identifying locations requiring bird diverters and implementing the appropriate device; and providing environmental orientation to construction crews. ird mortality will be monitored during annual line inspections. Impacts would be limited to the Project Area or may extend into the Project Area, would last less than one year, would be rare, naturally reversible, and negligible in magnitude. Therefore the impact is not likely to be significant. Yeo Substation Project Page 20 Attachment 2 Environmental Evaluation

80 Application to the Alberta Utilities Commission October PROGRAM OVERVIEW AND OBJECTIVES 1 ATCO Electric Ltd. (ATCO Electric) undertook a comprehensive participant involvement program for the Yeo Substation Project (the Project ) in accordance with Section 7 and Appendix A of AUC Rule 007: Applications for Power Plants, Substations, Transmission Lines and Industrial System Designations. The program included consultations with landholders, trappers, Aboriginal communities, government agencies, municipalities, and industrial parties. Consultation activities for the Project have been on-going for more than 7 months and will continue for the duration of the Project. 2 In designing and executing the participant 1 involvement program, ATCO Electric sought to inform and consult with all parties who may be directly and/or adversely affected by the Project. The objectives of the program were to provide these parties with project-specific information and opportunities to voice their concerns and ask questions. ATCO Electric undertook these activities with a commitment to work with potentially impacted and other interested parties to discuss options, address questions, concerns and, where practicable, resolve issues. 3 ATCO Electric s participant involvement program for the Project consisted of the following stages: Program Initiation early discussions with government agencies and industry Public notification selected route and site announced, input sought Consultations personal consultations on selected route and site Resolution of concerns route and substation site refinements identified, mitigation options discussed 4 The timing of activities included in ATCO Electric s participant involvement program for the Project are outlined in Table A. Details associated with each stage of the program are described in Sections 2 to 6. 5 Feedback obtained throughout the participant involvement program played an important role in project planning. Individual consultations generated new information that was used to identify additional route constraints, which were then considered during subsequent routing analysis. 1 For the purposes of this document, participant refers to all occupants, residents, landholders, agencies, municipalities and other interested parties contacted by ATCO Electric during its participant involvement program for this Project. Yeo Substation Project Page 1 Attachment 3 Participant Involvement Program

81 Application to the Alberta Utilities Commission October ATCO Electric succeeded in meeting program objectives to date. ATCO Electric was able to respond to all stakeholder concerns. There were no objections to the Yeo Substation Project. 7 Following submission of the Facility Application, all participants identified by ATCO Electric from the outset of the participant involvement program will receive any updates should changes in the project arise. Those on the route and in the vicinity of the substation site will be advised of the construction schedule and details prior to construction. Timing March 2014 July 2014 July September 2014 Table A: Timing of Key Program Activities Activity or Milestone Program initiation Early meetings and discussions with government, industrial parties, and others. Public notification Project information packages identifying the selected route and substation site were mailed to industry stakeholders, occupants, agencies, and trappers in the Project Study Area. Project details were published on ATCO Electric's website. Aboriginal consultation program was initiated. Consultations for the Project Personal consultations were conducted with landholders, occupants, agencies, First Nations and other interested parties within 800 m of the selected route and substation site. 2.0 PROGRAM INITIATION Pre-consultation activities were initiated in arch 214. Early activities included discussions with government and industry identified to have the significant influence in the project. eetings were held with representatives of agencies responsible for administering legislation potentially applicable to the Project. ATCO Electric also met with industrial participants who had mineral lease rights in the project area. The purpose was to inform these parties of the nature of the Project and that route planning was underway, and to obtain the latest information with respect to environmentally sensitive areas and future development plans in the Project area. Input from the meetings was used to identify routing constraints and preferences. Conceptual route and substation location options were discussed at these initial meetings. This input was combined with information gathered from maps and field assessments and other sources to identify the selected route based on the standard routing criteria described in Section 3 of the Application Text Attachment 1. Yeo Substation Project Page 2 Attachment 3 Participant Involvement Program

82 Application to the Alberta Utilities Commission October PUBLIC NOTIFICATION SELECTED ROUTE AND SITE 1 Following the identification of a selected route, ATCO Electric commenced the public notification stage of the participant involvement program. The purpose was to inform the public of the Project, to answer questions and address concerns of potentially affected participants and other interested parties, and to gather feedback regarding the selected route and substation. 11 In uly 214, ATCO Electric mailed written information about the Project. This information contained the selected route and substation site location, and was sent to landholders, occupants, agencies, First ations communities and trappers within metres (m) of the selected route, and Yeo 215S Substation and irchwood Creek 6S Substation sites. Other interested parties, such as municipalities and government departments were also mailed the information package. Over 3 information packages were distributed. 12 The materials distributed by mail were also made available on ATCO Electric s website and included the following: ATCO Electric brochures Project ewsletter Yeo Substation Project Project Fact Sheet Yeo Substation Project Alberta tilities Commission (AC) brochure Public Involvement in Needs and Facilities Applications Alberta Electric System Operator document Need for the Yeo 2015S Substation in the Fort McMurray Area Reply form and postage-paid return envelope osaic map showing the the Selected Route and Substation Site 13 A sample information package is included in Attachment 11. ATCO Electric s information brochures clearly describe various aspects of the Project including the consultation process and contained the following project-specific information: Project Planner s name and contact information (including website, phone, fax, , and mailing address) for requesting further information Description of the facilities and associated locations, including Selected Route and substation site (locations of facilities were also shown on mosaic maps included with the brochure) Diagrams of typical transmission line structures Description of the route and site selection process and the Facility Application process Proposed timeline for the Projectand Yeo Substation Project Page 3 Attachment 3 Participant Involvement Program

83 Application to the Alberta Utilities Commission October 2014 ackground information on ATCO Electric. 4.0 CONSULTATIONS SELECTED ROUTE AND SITE 14 ATCO Electric sought to conduct personal consultations with all landholders, occupants, and trappers within m of the proposed route and within m of the boundaries of the selected route, the proposed Yeo 215S Substation site and the approved irchwood Creek 6S Substation. These consultations were conducted in person, by phone, or through correspondence, based on the preference of the participant. Other interested parties, such as municipalities, government departments, and industry were also consulted. 15 The purpose of these consultations was to explain the potential impacts of the Project, to document the views and concerns of participants, and to collect sitespecific information about potential impacts. During these meetings, ATCO Electric representatives recorded participant concerns and feedback on the selected route and site and provided or arranged to provide additional information when requested. In some cases, additional visits and/or follow-up calls were made to participants, based on feedback from initial consultation. Personal consultations were also conducted with other interested parties including municipal, provincial and federal government agencies, industry, and Aboriginal communities. 16 Feedback from consultation was reviewed and entered into ATCO Electric s consultation tracking database. Input received during consultation and analysis of consultation results was used in combination with other standard routing criteria described in Section 3 of Attachment 1 to refine the route for the Project that ATCO Electric anticipated would have the least overall impact to the land, landholders and surrounding community. Yeo Substation Project Page 4 Attachment 3 Participant Involvement Program

84 Application to the Alberta Utilities Commission October SUMMARY OF PARTICIPANT FEEDBACK 17 ATCO Electric used its consultation tracking database to document the information collected during the participant involvement program. Systematic records were kept for each participant and included the following: Participant contact information Description of the land interest(s) held by the participant, by parcel Records of land titles for all parcels where land interests are held Records of all communications with the participant throughout the notification and consultation process Documentation of follow-up requests and follow-up activities ATCO Electric has carefully considered the feedback received from industry, government, Aboriginal communities and other interested parties. As comment forms were received by ATCO Electric, information from those forms was reviewed by Project staff and input into ATCO Electric s consultation tracking database. The comment form review process was used to identify issues or concerns that required follow-up and to identify site-specific opportunities to mitigate Project impacts. ATCO Electric considers the participant involvement program to be an important part of the planning and development process. Through meaningful discussions with government agencies, trappers, and industrial stakeholders, ATCO Electric acquired valuable feedback with regard to the Project and is working to completely address some minor concerns. here applicable, feedback was incorporated into Project design and planning. The following tables summarie the comments and concerns of participants directly affected by, or immediately adjacent to, the proposed Yeo Substation 215S, transmission lines L144 and alterations to L57 and approved irchwood Creek Substation 6S. 21 The following sections contain a comprehensive summary of the comments and concerns of participants directly affected by, or immediately adjacent to the proposed Yeo Substation 215S, approved irchwood Creek Substation 6S and transmission lines L144 and alterations to L57the nature of their land interestsand any concerns raised. Also included is ATCO Electric s response to concerns, where applicable. This information is presented as follows: Consultation with government agencies (Section 5.1) Consultation with industry landholders (Section 5.2) Yeo Substation Project Page 5 Attachment 3 Participant Involvement Program

ATCO Electric s pre-consultation with these agencies began in arch 214, through meetings to introduce the Project concept and Study Area and solicit information on known and potential developments. As participants, these agencies received all notification materials issued at each stage of the participant involvement program. 23 Consultation with these agencies was initiated with a phone call and/or to agency representatives to review and receive comments on project-specific information provided to them. ATCO Electric also met with a number of these agencies, where requested, to clarify or provide additional information and attempt to resolve specific concerns in relation to selected routes and sites. 24 A list of the specific concerns raised by agencies regarding the Project and ATCO Electric s responses is summaried in Table C. 5.2 CONSULTATION WITH INDUSTRY LANDHOLDERS 25 Industry participants holding various dispositions on land located within m of the edge of the right-of-way of the selected route and site were included in the Project notification. ATCO Electric completed personal consultations with industrial participants holding caveats and dispositions on land traversed by the right-of-way of the proposed route. These companies included oil and gas producers and large distribution and transmission pipelines. Table D contains a list of the individual concerns raised by industrial participants and ATCO Electric s associated responses. Concerns that were common to multiple industrial participants are further described in Sections to Separation from well sites and mitigation of electrical effects 26 Some of the companies consulted expressed no concerns, provided ATCO Electric observed the required separation from well sites and mitigated any electrical effects from the transmission line on pipeline facilities. Some also requested crossing agreements prior to commencement of Project construction. 27 ith respect to pipelines, ATCO Electric has agreed that it will reimburse owners for reasonable costs incurred for the analysis, design and installation of Yeo Substation Project Page 6 Attachment 3 Participant Involvement Program

86 Application to the Alberta Utilities Commission October 2014 mitigation measures demonstrated to be necessary as a result of the Project and enter into the necessary crossing and proximity agreements as is its usual practice regarding these facilities Pipelines paralleled and crossed 2 Two industrial parties indicated that they require a minimum distance of 1 metres between ATCO Electric s groundings and counterpoises and their pipes. ATCO Electric has notified these parties that we are unable to comply due to engineering requirements. The parties have followed up to confirm that any activities carried out on ATCO Electric s easement are acceptable. The pipeline integrity further reviewed engineering requirements. They recommended a corrosion study for ATCO Electric s activities. ATCO Electric will comply with that request. 5.3 CONSULTATION WITH TRAPPERS 2 ATCO Electric consulted with all trappers directly affected and/or within m of the Project. The trappers had no concerns or objections to this project. A list of the trappers consulted on the Proposed Routes and Site is located in Table D. This table also contains a summary of any comments raised by each participant and ATCO Electric s response, where applicable. 5.4 ABORIGINAL CONSULTATION 3 ATCO Electric s relationship with Aboriginal communities has evolved over the years and we continue to further enhance our relationships with Aboriginal communities. ATCO Electric believes that responsible development must take into account the issues and concerns of all ATCO Electric interest holders, including Aboriginal communities. Through information sharing, consultation and collaboration, ATCO Electric works with Aboriginal communities to understand issues and concerns to avoid and mitigate impacts within Aboriginal communities traditional lands wherever possible. 31 ATCO Electric identified three First ations as potential interest holders based on information from First ation communities and according to direction provided by Alberta Environment and Sustainable Resource Development. Starting in uly 214, ATCO Electric provided preliminary project information to the First ations. here a First ation confirmed interest, ATCO Electric then began a process to determine and address potential impacts. First ations were provided with additional project information as needed to help assess their interests and to aid in planning any further activities required to identify potential impacts. 32 Table contains a summary of the status of ATCO Electric s engagement with the three First ations.

123 ATCO Electric eo Substation Proect Environmental Protection Plan v. October Activity/Concern Fires (cont d) Archaeological, Palaeontological, or Historical Discovery Potential Mitigation Measures Ensure that exhaust and engine systems of equipment are in good working condition and inspect undercarriages periodically to ensure that grasses do not accumulate. If the fire hazard is high, do not leave vehicles idling for extended periods of time and parked on stubble or tall grass Station a full mobile water tank equipped with the required firefighting equipment near active construction sites when the fire hazard is high and air temperatures allow If the fire hazard is high, an evaluation will be conducted in consultation with the Contractor s Designated Fire Boss and Environmental Coordinator to assess mowing the RoW prior to construction to reduce potential ignition sources. Mow at appropriate times (i.e., early morning or late evening) when relative humidity is high and the temperature is cool, and accompany the mower with a water truck with appropriate fire-fighting equipment. In areas where mowing over rocky terrain could increase the risk of fire, use a non-metallic roller or equivalent to flatten down rather than mow grasses Ensure that each vehicle carries the fire-fighting equipment required by the Forest and Prairie Protection Act and Regulations and the minimum fire extinguishers as outlined in Appendix C. Each crew must also carry a two-way radio or cell phone Contact ATCO Electric to consult with applicable County, ESRD Operations Division or landowner to determine the preferred slash disposal method. If burning is preferred, obtain permission to burn from the County, ESRD Operations Division and/or landowner. Attend the fire and prevent fire from spreading off the RoW. Extinguish burning embers before leaving the site and monitor burn sites to ensure no smouldering debris remains. No burning shall be conducted during high winds Ensure that all crews have firefighting equipment on hand that is capable of controlling any fire that may occur as a result of their activities as per the Forest and Prairie Protection Act and Regulations Do not burn slash if the fire hazard is high or a fire ban has been issued. If burning is delayed, store slash along the RoW, in natural clearings or in approved push-outs. Approved burning may continue once the fire hazard is low and/or the fire ban has been rescinded Suspend work if archaeological, palaeontological or historical sites are discovered during construction to prevent any further disturbance to the site. No work at that particular location shall continue until permission is granted by Alberta Culture (AC). 15

163 ATCO Electric eo Substation Proect Environmental Protection Plan v. October APPENDIX B SPILLS CONTINGENCY PLAN Initial Response n the event of a spill of hazardous material, the first person on the scene will follow the actions presented below a) f possible without further assistance, assess the safety hazards of the situation, control danger to human life and identify the composition of the spilled material (see Spill Report Form). b) f feasible and safe to do so, remove any sources of ignition, cut off the source of the spill and initiate a release response plan (i.e., control, contain and clean-up). c) hile efforts have been initiated to contain the spill, immediately notify the Contractor s Designated Environmental ead andor the Environmental Coordinator. f the Contractor s Designated Environmental Lead andor the Environmental Coordinator cannot be immediately contacted, notify the Construction Supervisor. d) Once the source has been cut off, attempt to contain the spilled area. e) efore any reports are filed, take notice of dangers to the environment (e.g., proimity of watercourses, waterbodies or wetlands) and clean-up actions that might be necessary. f) f any of the tasks listed above are beyond the capabilities at hand, do not hesitate to ask for qualified assistance (e.g., Environmental Coordinators who can call specialty companies to assist). hen notified of a spill, Contractor s Designated Environmental Lead will immediately ensure that the Construction Supervisor and Environmental Coordinator are notified and provided with all information in the Spill Report Form; action is taken to control danger to human life including the appointment of an Onsite Supervisor to ensure health, safety and environmental protection mitigation measures are in place ; the appropriate approach for addressing the situation is determined in consultation with the Environmental Coordinator; and The Proect Emergency Response Plan is implemented, such that necessary equipment is mobilized and measures are being implemented to control and contain the spill. The Contractor will be required to make all resources available to contain and clean up a spill. General Spill Containment Procedures The successful containment of a spill on land or water depends on a variety of factors includingground cover and topography, hydrogeology, solubility of the material, viscosity of the liquid, water currents, soil permeability and climatic conditions. The procedures to be followed will be consistent with those described in Proect Emergency Response Plan.

164 ATCO Electric eo Substation Proect Environmental Protection Plan v. October The following general guidelines will be followed for containment of most hazardous materials. 1. Assess the safety hazards of the situation. 2. Remove sources of ignition, if safe to do so. 3. dentify the product, stop source and physically contain spill as soon as safe to do so.. Avoid use of water or fire etinguishing chemicals on nonpetroleum product spills unless it is necessary to control a fire or prevent an eplosion, since many chemicals react violently with water and chemical etinguishing agents may release toic fumes. n addition, chemicals may be soluble in water and dispersal makes containment and clean up more difficult.. Reduce traffic on contaminated soils. 6. se natural depressions or berms constructed with materials and equipment in proimity to the site to physically contain a spill on land. Deployment of booms will be necessary on water. eneral clean-up guidelines for specific incidents are outlined below; details of procedures are contained within the Proect Emergency Response Plan. Transportation by Truck At a minimum, the following general guidelines will be followed for containment and clean-up of most hazardous materials if spilled from a fuel truck. 1. Contain spilled petroleum product. 2. Pump tanker dry if the tanker is compromised and at risk of further release (into appropriate containers or another tanker). 3. Remove tanker from site.. Recover spilled product.. Clean-up contaminated area. 6. Dispose of sorbent pads, heavily contaminated soil and vegetation at an approved facility. On lightly contaminated soil areas where remediation is feasible, add amendments, repeat as required, sample soil and seed as appropriate. Repeat as required.. Remediate the affected area, as required. Spills Adjacent to or into a Watercourse, Waterbody or Wetland At a minimum, the following general guidelines will be followed for containment and clean-up of most hazardous materials if spilled adacent to, or into, a watercourse, waterbody or wetland. 1. Construct berm andor trenches to contain spilled product prior to entry into a watercourse, waterbody or wetland. 2. Deploy booms, skimmers, sorbents, etc., if feasible, to contain and recover spilled material from watercourse, waterbody or wetland. 3. Recover spilled product.. Clean-up contaminated area including downstream shorelines. 6

165 ATCO Electric eo Substation Proect Environmental Protection Plan v. October Spot Spills. Dispose of heavily contaminated soil and vegetation at an approved facility. 6. Remediate the affected area, as required. Since impacts from small spot spills can generally be reduced if appropriate actions are implemented, all small spills of fuels or noious materials must be reported immediately to the Contractor s Designated Environmental ead. At a minimum, the following general guidelines will be followed while cleaning up spot spills of fuel or other hazardous materials. 1. Suspend construction activity in the immediate vicinity of the spot spill until permission to resume activity has been granted by the Contractor s Designated Environmental Lead. 2. The Contractor s Designated Environmental Lead will consult with the Environmental Coordinator, to determine appropriate methods to remove or restore contaminated soils. Soil and vegetation heavily contaminated with petroleum products will be incinerated or disposed of at an approved facility. 3. ocations where spot spills occur are to be flagged or otherwise marked to ensure that post-construction monitoring of the site can be undertaken.. Remediate the affected area, as required. Sampling and Analysis Soil or water sampling will occur on a case by case basis considering the quantity released and the site specific conditions, as determined by the Environmental Coordinator. The sampling will confirm the remedial actions have effectively removed contamination from the affected area. Sample analysis will be based on spilled material and site specific conditions, and will follow the Alberta Tier 1 Soil and Groundwater Remediation Guidelines or the Alberta Tier 2 Soil and Groundwater Remediation Guidelines for parameters of concern. Regulatory Reporting mmediate verbal reporting to ESRD must be completed at the first available opportunity for any spill or release that may cause, is causing, or has caused an adverse effect on the environment. Call (toll-free, 2 hours-a-day) or to report a spill, release, or environmental emergency. The Environmental Coordinator will contact the appropriate regulatory agency to report spills eceeding the volumes listed below. ATCO Electric has set release reporting requirements that are more stringent than the quantities specified by ESRD and has done so to address the general condition of adverse effects related to the release. The quantities include

166 ATCO Electric eo Substation Proect Environmental Protection Plan v. October PC oils Oils (hydraulic, used, transformer, etc.) asoline, diesel, glycols Ozone depleting substances (ODS such as CF and refrigerants) and SF6 Any amount where the concentration is 2 ppm from equipment not currently in use, or 1 g if from in-use equipment, or if, in a raw case, the oil is suspected to contain PC but the concentration is unknown. litres 0 litres 10 kg or any quantity that could pose a danger to public safety. A written report must be submitted directly to ESRDs Monitoring Division within seven days of verbally reporting a release, unless it was specifically waived at the time of the immediate report. Internal Reporting The Contractor Contractor s Designated Environmental Lead is responsible for ensuring immediate notification to the Environmental Coordinator and Construction Supervisor and include all information in the Spill Report Form. Additionally, a written incident report will be completed by the Contractor responsible for the spill, and will provide details of the incident investigation.

177 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX F SILTATION OF WATERCOURSES, WATERBODIES OR WETLANDS CONTINGENCY PLAN The Environmental Coordinator will maintain a record of the location, timing and reason for implementation of the contingency plan. Appropriate authorities such as ESRD and DO will be notified as soon as practical, by the Environmental Coordinator, that contingency measures have been implemented. See also the lood and Excessive low Contingency Plan (Appendix I). Should an extreme precipitation/streamflow event threaten, or other circumstances occur which may render the existing sediment control measures inadequate, the procedures outlined below will be implemented progressively or individually as warranted. Prohibit the operation of construction equipment within 3 m of the banks or edges of watercourses, waterbodies or wetlands. Install additional silt fencing, or equivalent, to prevent silt-laden water from entering watercourse, waterbody or wetland. Excavate cross ditches to divert runoff away from watercourses, waterbodies or wetlands. Construct berms of subsoil, sandbags, rock, timber, straw bales or hay bales on approach slopes and/or banks to divert runoff from the RoW and onto well-vegetated lands. The location and material of the sediment control structures will be determined by the Environmental Coordinator. Import sand bags and place strategically to help stabilie and add height to banks to prevent flooding of nearby areas, especially where vegetation has been removed. 69

178 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX G SOIL/SOD PULVERIZATION CONTINGENCY PLAN Where warranted, ESRD and/or the appropriate County representative will be notified as soon as practical that contingency measures have been implemented. Criteria for Implementation Pulveriation may occur on unstripped well-sodded lands, particularly on sandy or silty soil and on cultivated lands with fine textured soils. The Soil/Sod Pulveriation Contingency Plan will be implemented where sod integrity on hay and/or pasture lands or topsoil has been disturbed to the extent that the soil/sod will lose it s structure, or there is an unacceptably high risk of soil erosion. The following contingency measures will be implemented where pulveriation is occurring and topsoil was not fully salvaged. ocations where these measures apply will be determined by the Environmental Coordinator in consultation with the landowner and/or occupant and/or applicable government agency (e.g., ESRD and/or the County). Provide alternative access to avoid areas prone to soil/sod pulveriation. Reduce traffic in areas where soil and/or sod is prone to pulveriation. Use equipment with wide pad tracks during soils handling (i.e., salvaging and replacing topsoil). Salvage a wider area of topsoil. Implement other suitable mitigation depending on conditions encountered during construction (e.g., availability of extra workspace, soil moisture levels, land use, etc.). Implement the following measures during clean-up and reclamation activities where soil/sod pulveriation occurred prior to contingency measures being implemented. ightly cultivate the affected areas in two directions with a spike cultivator or a scarifier. arrow the area to prepare a seed bed. Drill or broadcast seed the area as appropriate and if necessary lightly harrow the area again to cover all seed and compact the seed bed. Add straw crimp, if warranted, on erosion prone soils and if approved by the land authority. 7

179 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX H WET/THAWED SOILS CONTINGENCY PLAN ATCO Electric will assign Environmental Coordinators with sufficient training and soils-related experience to be able to identify soils that are too wet for a particular activity and when the soils are sufficiently dry to allow the activity to resume. The decision to continue or suspend particular construction activities on lands with excessively wet/thawed soils will be made by the Construction Supervisor in consultation with the Contractor s Designated Environmental ead, and the Environmental Coordinator. A record of the location, timing and reason for implementation of the Wet/Thawed Soils Contingency Plan will be maintained by the Environmental Coordinator. Soils are considered to be excessively wet when the planned activity could cause damage to soils either due to rutting by traffic through the topsoil into the subsoilsoil structure damage during soil handlingor compaction and associated pulveriation of topsoil structure damage due to heavy traffic. Contingency measures will be implemented, if warranted, once one of the following indicators occurs rutting of topsoil to the extent that admixing may occur excessive wheelslip excessive build-up of mud on tires and cleats formation of puddlesor tracking of mud as vehicles leave the work or travel area. To reduce terrain disturbance and soil structure damage through rutting or compaction due to wet/thawed soil conditions, construction alternatives will be employed, as necessary, in the event of thawed soils during froen conditions and/or an excessively wet surface during non-froen conditions. The contingency measures listed below will be implemented individually or in combination, as necessary, based on site-specific conditions. Wet Soil Contingency Measures Restrict construction traffic, where feasible, to equipment with low-ground pressure tires or wide pad tracks. Work only in non-problem areas, such as well-drained soil or well-sodded lands, until conditions improve. Install geotextiles or matting in problem areas. Consider salvaging an additional width of topsoil in wet areas. Suspend construction until soils dry out. Thawed Soil Contingency Measures Restrict construction traffic, where feasible, to equipment with low-ground-pressure tires or wide pad tracks. Work only in non problem areas, such as froen or well-drained soils, until conditions improve. Postpone construction until evening or early morning when the ground is froen. Install geotextiles or matting in problem areas. Employ frost inducement measures such as snow packing or plowing to increase the load-bearing capacity of thawed ground. Suspend construction until soils dry out or freee. 71

180 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX I FLOOD AND EXCESSIVE FLOW CONTINGENCY PLAN Notify Environmental Coordinator and/or the Construction Supervisor that contingency measures have been initiated as a result of flooding or excessive stream flow along the route. Construction Supervisor and/or Environmental Coordinator will record the location, timing and reason for implementation of the contingency plan. Appropriate authorities such as ESRD, and DO will be notified, as soon as practical, by the Environmental Coordinator, that contingency measures have been implemented. See also Siltation of Watercourses Contingency Plan (Appendix ). The weather conditions will be monitored by the Environmental Coordinator on a daily basis. If a major storm is predicted or occurs, qualified personnel will inspect all watercourse crossings where vehicle/equipment crossing structure installation is in progress or has been completed, if applicable, to determine whether any corrective actions need to be implemented. If the potential for siltation of a watercourse due to contractor activity is predicted, the contingency plans for Soil Erosion and for Siltation of Watercourses (Appendix D and Appendix ) will be implemented. The following contingency measures will be implemented progressively or individually, as warranted, if excessive flow or flood conditions are anticipated prior to commencing vehicle/equipment crossing structure installation. Assess the capability to handle the forecasted flow rate with the proposed vehicle/equipment crossing structure. If use of the proposed crossing structure is determined by ATCO Electric to be still feasible, the crossing will proceed. Defer vehicle/equipment crossing structure installation to a later time when flows have subsided, if determined by ATCO Electric that the proposed crossing method is not feasible. Alternatively, where the forecasted flow rates and window limitations combine to preclude the proposed crossing structure, request the appropriate authority (e.g., DO, ESRD) for permission to use an approved alternative crossing structure. The following contingency measures will be implemented progressively or individually, as warranted, if excessive flow or flood conditions should occur during vehicle/equipment crossing structure installation, if applicable. Withdraw all equipment or tanks containing fuel, oil or other haardous materials from potential flood areas. Relocate all topsoil piles at the direction of the Environmental Coordinator. Relocate spoil piles, to the extent feasible, to a position above the anticipated high water level. Remove all stationary and mobile equipment deployed at the crossing site to a safe area above the anticipated high water level. Evaluate vehicle crossing structure to determine whether adequate free-board is present on bridges and adequate capacity is available in culverts. Take corrective measures as appropriate to avoid flooding of adjacent lands. 72

181 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX J PLANT SPECIES OF CONCERN DISCOVERY CONTINGENCY PLAN In the event that listed vascular plants, or sensitive ecological communities are discovered during future vegetation studies for the Project, the plant or ecological community will be assessed and appropriate mitigative measures will be determined prior to construction of the Project. The appropriate mitigative measures will be determined following an assessment, which will include the location of the plant or ecological community the relative rarity listing of the plant or ecological community (regionally, nationally, etc.) the local abundance of the plant or ecological community the growth habit and propagation strategy of the plant or ecological communityand the habitat preferences of the plant or ecological community. itigative options that may be implemented include avoiding the listed plant species or community and flagging and fencing off the occurrence informing all users of access restrictions along native vegetation segments and in the vicinity of flagged or fenced sites temporarily covering the site with geotextile pads, flex net, or rig mats realigning the travel lane or workspaces to avoid the siteor propagating listed plants or ecological communities (e.g., by harvesting seed, salvaging and transplanting sod or collecting cuttings of the listed species or community). 73

182 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX K WILDLIFE ENCOUNTER CONTINGENCY PLAN In the event of an encounter with wildlife during the construction phase of the Project, either at the construction site or on the commute to and from the construction sitefollow the measures outlined below. 1. Report any incidents (e.g., aggressive behaviour, nuisance behaviour) with wildlife to the Environmental Coordinator who will, if warranted, immediately notify the local ESRD Wildlife iologist and the local police detachment. 2. Report any trapped, injured, or dead animals on the site to the Environmental Coordinator. If warranted (i.e., wildlife identified are listed either provincially or federally), the Environmental Coordinator will contact local ESRD Wildlife iologist to consult on appropriate action. 3. Report location and details of collisions with wildlife to the Environmental Coordinator. If warranted (i.e., wildlife identified are listed either provincially or federally), the Environmental Coordinator will notify local ESRD Wildlife iologist and the local police detachment. 4. Once the preceding contacts have been made, the Environmental Coordinator will also contact ATCO Electrics environment staff to report the situation. 74

183 ATCO Electric eo Substation Project Environmental Protection Plan v. October APPENDIX L WILDLIFE SPECIES OF CONCERN DISCOVERY CONTINGENCY PLAN Listed Wildlife Species Discovery Prior to Construction In the event that listed wildlife species or their site-specific habitats are discovered during future wildlife studies for the Project, the discovery will be assessed and appropriate mitigation will be determined in conjunction with ATCO Electric s Avian Protection Plan (APP), and consultation with ESRD. The wildlife or habitat will be assessed based on the following criteria the location of the wildlife or habitat feature with respect to the proposed area of development the presence of topographic features or vegetation to effectively screen the wildlife or habitat from construction activities the timing of construction versus the critical timing constraints for the speciesand the potential for an alteration of construction activities to reduce or avoid sensory disturbance. The mitigative measures available include, but are not limited to, the following abide by seasonal timing constraints within the recommended set back distances abide by daily timing restrictions on construction activities narrow down the proposed area of disturbance and protect the site using fencing or clearly mark the site using flagging alter or delay construction activities to avoid sensory disturbance (e.g., no burning) inform all users of access restrictions in the vicinity of flagged or fenced sites realign the travel lane or workspaces to avoid the site install nest boxes or platforms or otherwise replace or enhance habitat during reclamation or restorationand relocate nests or other habitat features or individuals if practical and in consultation with ESRD ish and Wildlife staff and monitor post-construction response. The Environmental Alignment Sheets will incorporate recommended mitigative measures for the given situation, if applicable. Listed Wildlife Species Discovery During Construction In the event that listed wildlife species or their site-specific habitat is discovered during construction, the discovery will be assessed and appropriate mitigation measures from the list above will be determined in conjunction with ATCO Electric s APP, and in consultation with ESRD. isted wildlife species and their habitat characteristics that could occur within the Project area will be identified in the Environmental Education Program for the Environmental Coordinators. The Environmental Coordinators will be provided with detailed information on identifying listed wildlife species and their site-specific habitat. 75

184 ATCO Electric eo Substation Project Environmental Protection Plan v. October In the event that listed wildlife species or their site-specific habitats are discovered during construction, follow the measures outlined below. 1. Suspend work immediately in the vicinity of any newly discovered wildlife species of concern. Work at that location may not resume until the measures below are undertaken. 2. Notify the Environmental Coordinator who will notify the Construction Supervisor. 3. The Environmental Coordinator will assess the discovery and either allow construction to be resumed or, in the event of a confirmed or potential discovery, proceed by notifying ESRD ish and Wildlife Division and, if required, retaining the services of a qualified third party wildlife biologist. Listed Wildlife Species Discovery During Operations and Maintenance The following is adapted from ATCO Electrics Practice 141irds of Prey - Nest anagement If a migratory bird, or bird of prey, is encountered on one of ATCO Electrics structures and is causing an outage, immediately contact the local ESRD Operations Division, Wildlife iologist. The Wildlife iologist must be advised of the situation and that there is an immediate need to disturb the nest. Any action requires the Wildlife iologists endorsement. It is a regulatory offence to disturb or destroy the contents of an active nest (and, specifically, if the disturbance deals with a nest for a species at risk - at any time) without verbal or written permission from the local Wildlife iologist. The information to be provided, recogniing the time/season of the year, includes a) the status of the nest (e.g., is it known to be active with eggs or nestlings are present), b) is the nest under construction, and c) the seriousness (e.g., nature and extent) of the outage. ased on this initial assessment, work with the local Wildlife iologist to determine a course of action that will address the outage and the current status of the nest. Potential options for consideration may include but are not limited to trim any branches that may be causing the fault temporarily relocate the conductor farther away from the nest add insulation to temporarily address the existing situation install a line cover-up to temporarily address the situationor as a last resort, and only with verbal and/or written permission of the local Wildlife iologist, remove the active nest and its contents from the structure. In some cases it may be possible to work with the local Wildlife iologist to salvage the entire nest or the contents of an active nest. This work must receive permission from the Wildlife iologist and should only be undertaken with the support and assistance of the Wildlife iologist on the condition that the work can be conducted safely, protecting against electrical contacts and protection against any attack by birds attending the nest. ATCO Electric would generally prefer not to provide a nesting structure adjacent to existing transmission lines. Although this may deal with a nest on the live structure, it does not move the bird away from the transmission linetherefore, the potential for an avian contact with the line in the nesting area remains. When a nest is discovered on a structure, submit a Nest anagement Reporting orm to ATCO Electric Environmental Affairs. 76

187 ATCO Electric Yeo Substation Project Environmental Protection Plan v. October APPENDIX M FISHERIES AND OCEANS CANADA MEASURES TO AVOID CAUSING HARM TO FISH AND FISH HABITAT PROJECT PLANNING Timing Time work in water to respect timing windows to protect fish, including their eggs, juveniles, spawning adults and/or the organisms upon which they feed; Minimize duration of in-water work; Conduct in-stream work during periods of low flow, or at low tide, to further reduce the risk to fish and their habitat or to allow work in water to be isolated from flows; and, Schedule work to avoid wet, windy and rainy periods that may increase erosion and sedimentation. Site Selection Design and plan activities and works in waterbody such that loss or disturbance to aquatic habitat is minimized and sensitive spawning habitats are avoided. Design and construct approaches to the waterbody such that they are perpendicular to the watercourse to minimize loss or disturbance to riparian vegetation. Avoid building structures on meander bends, braided streams, alluvial fans, active floodplains or any other area that is inherently unstable and may result in erosion and scouring of the stream bed or the built structures. Undertake all in-stream activities in isolation of open or flowing water to maintain the natural flow of water downstream and avoid introducing sediment into the watercourse. Contaminant and Spill Management Plan activities near water such that materials such as paint, primers, blasting abrasives, rust solvents, degreasers, grout, or other chemicals do not enter the watercourse. Develop a response plan that is to be implemented immediately in the event of a sediment release or spill of a deleterious substance and keep an emergency spill kit on site. Ensure that building material used in a watercourse has been handled and treated in a manner to prevent the release or leaching of substances into the water that may be deleterious to fish. 79

188 ATCO Electric Yeo Substation Project Environmental Protection Plan v. October EROSION AND SEDIMENT CONTROL Develop and implement an Erosion and Sediment Control Plan for the site that minimizes risk of sedimentation of the waterbody during all phases of the project. Erosion and sediment control measures should be maintained until all disturbed ground has been permanently stabilized, suspended sediment has resettled to the bed of the waterbody or settling basin and runoff water is clear. The plan should, where applicable, include o Installation of effective erosion and sediment control measures before starting work to prevent sediment from entering the water body. o Measures for managing water flowing onto the site, as well as water being pumped/diverted from the site such that sediment is filtered out prior to the water entering a waterbody. For example, pumping/diversion of water to a vegetated area, construction of a settling basin or other filtration system. o Site isolation measures (e.g., silt boom or silt curtain) for containing suspended sediment where in-water work is required (e.g., dredging, underwater cable installation). o Measures for containing and stabilizing waste material (e.g., dredging spoils, construction waste and materials, commercial logging waste, uprooted or cut aquatic plants, accumulated debris) above the high water mark of nearby waterbodies to prevent re-entry. o Regular inspection and maintenance of erosion and sediment control measures and structures during the course of construction. o Repairs to erosion and sediment control measures and structures if damage occurs. o Removal of non-biodegradable erosion and sediment control materials once site is stabilized. SHORELINE RE-VEGETATION AND STABILIZATION Clearing of riparian vegetation should be kept to a minimum: use existing trails, roads or cut lines wherever possible to avoid disturbance to the riparian vegetation and prevent soil compaction. When practicable, prune or top the vegetation instead of grubbing/uprooting. Minimize the removal of natural woody debris, rocks, sand or other materials from the banks, the shoreline or the bed of the waterbody below the ordinary high water mark. If material is removed from the waterbody, set it aside and return it to the original location once construction activities are completed. Immediately stabilize shoreline or banks disturbed by any activity associated with the project to prevent erosion and/or sedimentation, preferably through re-vegetation with native species suitable for the site. Restore bed and banks of the waterbody to their original contour and gradient; if the original gradient cannot be restored due to instability, a stable gradient that does not obstruct fish passage should be restored. If replacement rock reinforcement/armouring are required to stabilize eroding or exposed areas, then ensure that appropriately-sized, clean rock is used; and that rock is installed at a similar slope to maintain a uniform bank/shoreline and natural stream/shoreline alignment. Remove all construction materials from site upon project completion.

189 C lectric eo Substation roject nvironmental rotection lan v. October FISH PROTECTION nsure that all in-water activities, or associated in-water structures, do not interfere with fish passage, constrict the channel width, or reduce flows. Retain a qualified environmental professional to ensure applicable permits for relocating fish are obtained and to capture any fish trapped within an isolated/enclosed area at the work site and safely relocate them to an appropriate location in the same waters. Fish may need to be relocated again, should flooding occur on the site. Screen any water intakes or outlet pipes to prevent entrainment or impingement of fish. ntrainment occurs when a fish is drawn into a water intake and cannot escape. Impingement occurs when an entrapped fish is held in contact with the intake screen and is unable to free itself. o In freshwater, follow these measures for design and installation of intake end of pipe fish screens to protect fish where water is extracted from fish-bearing waters: Screens should be located in areas and depths of water with low concentrations of fish throughout the year. Screens should be located away from natural or artificial structures that may attract fish that are migrating, spawning, or in rearing habitat. he screen face should be oriented in the same direction as the flow. nsure openings in the guides and seals are less than the opening criteria to make fish tight. Screens should be located a minimum of mm ( in.) above the bottom of the watercourse to prevent entrainment of sediment and aquatic organisms associated with the bottom area. Structural support should be provided to the screen panels to prevent sagging and collapse of the screen. arge cylindrical and box-type screens should have a manifold installed in them to ensure even water velocity distribution across the screen surface. he ends of the structure should be made out of solid materials and the end of the manifold capped. eavier cages or trash racks can be fabricated out of bar or grating to protect the finer fish screen, especially where there is debris loading (woody material, leaves, algae mats, etc.). mm ( in.) spacing between bars is typical. rovision should be made for the removal, inspection, and cleaning of screens. nsure regular maintenance and repair of cleaning apparatus, seals, and screens is carried out to prevent debris-fouling and impingement of fish. umps should be shut down when fish screens are removed for inspection and cleaning. void using explosives in or near water. se of explosives in or near water produces shock waves that can damage a fish swim bladder and rupture internal organs. lasting vibrations may also kill or damage fish eggs or larvae. If explosives are required as part of a project (e.g., removal of structures such as piers, pilings, footings; removal of obstructions such as beaver dams; or preparation of a river or lake bottom for installation of a structure such as a dam or water intake), the potential for impacts to fish and fish habitat should be minimized by implementing the following measures:

October o o o o o o o o ime in-water work requiring the use of explosives to prevent disruption of vulnerable fish life stages, including eggs and larvae, by adhering to appropriate fisheries timing windows. Isolate the work site to exclude fish from within the blast area by using bubble/air curtains (i.e., a column of bubbled water extending from the substrate to the water surface as generated by forcing large volumes of air through a perforated pipe/hose), cofferdams or aquadams. Remove any fish trapped within the isolated area and release unharmed beyond the blast area prior to initiating blasting Minimize blast charge weights used and subdivide each charge into a series of smaller charges in blast holes (i.e., decking) with a minimum millisecond (/ seconds) delay between charge detonations (see Figure ). ack-fill blast holes (stemmed) with sand or gravel to grade or to streambed/water interface to confine the blast. lace blasting mats over top of holes to minimize scattering of blast debris around the area. o not use ammonium nitrate based explosives in or near water due to the production of toxic by-products. Remove all blasting debris and other associated equipment/products from the blast area. OPERATION OF MACHINERY nsure that machinery arrives on site in a clean condition and is maintained free of fluid leaks, invasive species and noxious weeds. Whenever possible, operate machinery on land above the high water mark, on ice, or from a floating barge in a manner that minimizes disturbance to the banks and bed of the waterbody. imit machinery fording of the watercourse to a one-time event (i.e., over and back), and only if no alternative crossing method is available. If repeated crossings of the watercourse are required, construct a temporary crossing structure. se temporary crossing structures or other practices to cross streams or waterbodies with steep and highly erodible (e.g., dominated by organic materials and silts) banks and beds. For fording equipment without a temporary crossing structure, use stream bank and bed protection methods (e.g., swamp mats, pads) if minor rutting is likely to occur during fording. Wash, refuel and service machinery and store fuel and other materials for the machinery in such a way as to prevent any deleterious substances from entering the water.

222 SHAPE the conversation July PROJECT NEWSLETTER YEO SUBSTATION PROJECT The Yeo substation project is necessary to connect a proposed industrial pump station facility to the electrical system. The project is located approximately 40 kilometres (km) west of Fort McMurray in the Regional Municipality of Wood Buffalo. If approved, the project will include the construction of the Yeo substation, (to be called 2015S) and approximately 1.5 km of new transmission line (to be called 9L144). The new transmission line will connect the planned Yeo substation to the approved Birchwood Creek substation (called 960S). The project will also include the removal and re-routing of approximately 600 metres (m) of existing transmission line (called 9L57). ATCO Electric is seeking your input on how this project may affect you. Since the 1980s, growth of Alberta s electric system has not kept pace with Albertans rising electricity needs. New projects are being planned to meet those needs. ATCO Electric s consultations with landholders on transmission projects routinely lead to improvements on our projects. We have adjusted project plans as a result of feedback and conversations with landholders. Please provide your feedback on this project and help shape the conversation. Did you know... ATCO Electric - A Regulated Utility Alberta s electrical system is regulated by the Alberta Utilities Commission (AUC). The AUC is a quasi-judicial agency that ensures the services provided by ATCO Electric and other Alberta utilities take place in a fair and responsible manner and are in the public s interest. Before ATCO Electric can begin construction on a project, the AUC must approve the facilities application, which includes details such as the location of transmission facilities and routes. For more information, please refer to the enclosed AUC brochure. This package provides important project information and outlines ATCO Electric s public consultation process. We invite any comments, questions or concerns you may have. Please refer to the back page for our contact details.

Consultation with landholders routinely leads to improvements on our projects. We have adjusted facility locations and modified our plans because of conversations with landholders. Your feedback will help us confirm the suitability of the selected substation site and transmission line route. In selecting the substation site and transmission line routes, ATCO Electric must consider a range of site and route constraints and barriers (see Transmission Facilities on next page). In addition to the in-person and telephone consultations that ATCO Electric will undertake, we invite anyone who is interested in this project to: Provide feedback and share other information using the enclosed reply form and postage paid envelope. Be a part of the conversation. If you have any questions, concerns or other information regarding this project, we want to hear from you. THE SCHEDULE Public consultation begins with sharing information about the project in order to find the best options We gather your input. Based on this input and other factors, adjustments to plans may be made. ATCO Electric submits an application to the AUC to build the proposed facilities. The AUC reviews the application in a public process.* If approved, construction of the new facilities begins. PUBLIC CONSULTATION is a continuous process that occurs throughout the life of the project. *For more information about how you can participate in the AUC process, please refer to the enclosed brochure entitled: Public Involvement in Needs or Facilities Applications.

224 The Right-of-Way The term right-of-way refers to the area a transmission line uses - including areas on either side of the line. Right-of-ways must have a minimum width to ensure safety and ongoing access for maintenance. For safety reasons, some general restrictions on the use of the land in the direct vicinity of the transmission line may apply. These include setbacks for development. The right-of-way: will follow property boundaries if feasible. in some situations, will follow existing features like a road, pipeline or another power line. typical right-of-way width for this project is 34 metres. other dimensions will depend on the type and size of the required structure, existing land use, surrounding features and other factors. Once proposed routes have been submitted to the AUC, ATCO Electric will submit an application to Alberta Environment and Sustainable Resource Development (AESRD) to obtain the land rights for a right-of-way on crown land. Transmission Facilities The selected site for the Yeo substation was chosen to ensure: suitable site conditions; good access; sufficient space for initial development and incoming lines; adequate setback from adjacent development; and optimal usage of existing disturbed areas. The selected routes for the transmission lines were chosen to: minimize fragmentation to oil sands leases and the environment; follow existing linear disturbances, other rightsof-way or property boundaries wherever possible; minimize impacts on pipelines, oil and gas operations, electrical right-of-ways, and communication facilities; and maximize safety. The enclosed map shows the selected site and transmission line routes for this project. Facility locations may be adjusted in response to feedback, landholder consultations and ongoing study of the project area. If you are in the vicinity of the planned project, ATCO Electric will contact you to schedule a personal consultation. Anyone who is interested in speaking with ATCO Electric about this project can contact us to arrange a consultation at their convenience. Please see our contact information on the back page. Once feedback has been considered and the project details have been finalized, ATCO Electric will submit a facilities application to the AUC to obtain approval for the construction and operation of the planned transmission facilities. project notification (selected site & route) OCTOBER 2014 application filed with the AUC DECEMBER 2015 facilities completed and operating JULY 2014 to AUGUST 2014 JANUARY 2015 to DECEMBER 2015 consultation with landholders if approval is granted by the AUC, construction begins

226 The Technical Details July 2014 PROJECT FACT SHEET 1 YEO SUBSTATION PROJECT The technical details of facilities associated with the Yeo substation project are described in this fact sheet. Designs may vary as plans are finalized. Planned Yeo 2015S Substation If approved, the planned Yeo substation will be constructed and located approximately 40 kilometres (km) west of Fort McMurray in the Regional Municipality of Wood Buffalo on the southwest quarter of Section W4M (see enclosed Reference Map). New 240-kV Transmission Line 9L144 Approximately 1.5 km of new transmission line will be built to connect the new Yeo substation (to be called 2015S) to the approved Birchwood Creek substation (to be called 960S) (see enclosed map). Approved Birchwood Creek 960S Substation The approved Birchwood Creek 960S substation is located on the northeast quarter of section W4M, approximately 440 metres east of the planned Yeo substation (see enclosed Reference Map). This substation will be altered in order to provide power to the new 9L144 transmission line. THE DETAILS The new Yeo substation (to be called 2015S) will include the following equipment (refer to the back of this fact sheet for equipment definitions): two 240/25-kilovolt (kv) transformers two 240-kV circuit breakers control building installation of a new fence measuring approximately 82 metres (m) by 57 m associated switches and equipment THE DETAILS If approved, the 9L144 transmission line will be 240-kV and approximately 1.5 km long. The line will consist of: three conductor wires one overhead OPGW shield wire H-Frame structure The typical structure is described in more detail on the back of this fact sheet. THE DETAILS As part of the Yeo substation project, the following new equipment will be installed at the Birchwood Creek substation: one 240-kV disconnect switch one 240-kV circuit breaker

227 What It Will Look Like If approved by the Alberta Utilities Commission, the 240-kilovolt (kv) transmission line will be built with single circuit H-Frame structures similar to the one shown here. Structures will be single-circuit. This means that they will have one set of three wires strung across them. An optical protection ground wire (OPGW) will be strung overhead from the tops of the structures to protect the line from lightning. The distance between structures will range from 150 to 225 metres (m). Non-typical structures with wider bases and/or guy wires and anchors may be required where the line ends or bends, at corners and to go over and around obstacles. In all cases minimum clearance will meet or exceed the requirements of provincial safety regulations. 19 m APPROXIMATE DIMENSIONS Height m Maximum width (including insulators m Distance between structures m *Details may change as the project develops and designs are finalized. 15 m Typical right-of-way for this project is 34 m Right-of-ways are cleared of trees, bush and debris to allow access for construction and ongoing maintenance. Additional vegetation clearing may be required outside the proposed easement. Definitions Circuit: A circuit is a group of wires electricity flows through. ATCO Electric s transmission lines can be single or double circuit. A single circuit line has three wires and a double circuit line has six. A transmission line may also have one or two shield wires on the top of the structures to protect the line from lightning. Circuit breaker: An automatic switch that is designed to protect an electrical circuit from overloading by shutting off the flow of electricity. Conductor wire: A bundle of metal wire strung across transmission structures that transports electricity along its length. Consultation: A meeting where advice, information and views are exchanged. Control building: The substation control building contains switchboard panels, batteries, battery chargers, supervisory control, power-line carrier, meters, and relays. The control building provides all weather protection and security for the substation control equipment. Easement: A right to use private or crown land for the placement of transmission lines and structures. Kilovolt (kv): A kilovolt is equal to one thousand volts. This unit of measurement is most commonly used when describing transmission and distribution lines. Distribution and transmission lines in Alberta carry between 4-kV (4,000 volts) and 500-kV (500,000 volts). OPGW shield wire: An Optical Protection Ground Wire (OPGW) is strung across the top of the transmission line where it shields conductor wires from lightning. Includes a fibre optic core that provides a path for telecommunications. Right-of-way: A right-of-way is the use of a strip of land acquired for the construction and operation of a transmission line. The term right-of-way is also used to refer to the physical space a transmission line encompasses, including areas on either side of the line. Transformer: A transformer is the device in a substation that steps voltage up or down. It transforms the electricity from higher transmission voltages to the lower distribution voltages that power your home. consultation@atcoelectric.com (toll free)

229 Need for the Yeo 2015S Substation in the Fort McMurray area Transmission Development Information for Stakeholders ATCO Electric Ltd. (ATCO) has applied to the Alberta Electric System Operator (AESO) for transmission system access to connect a new pump station west of Fort McMurray. ATCO s request can be met by developing a new 240/25 kv substation, to be called Yeo 2015S, and a new 240 kv transmission line to connect Yeo 2015S to the Birchwood Creek 960S substation. The AESO is processing ATCO s request, including providing information to landowners, occupants, residents and agencies that may be near the proposed transmission development. The AESO intends to apply to the Alberta Utilities Commission (AUC) for approval of this need in the fall of The AESO s needs identification document (NID) application will be available on the AESO s website at at the time of its application to the AUC. Who is the AESO? Alberta s transmission system, sometimes referred to as the Alberta Interconnected Electric System (AIES), is planned and operated by the AESO. The transmission system comprises the high-voltage lines, towers and equipment (generally 69 kv and above) that transmit electricity from generators to lower voltage systems that distribute electricity to cities, towns, rural areas and large industrial customers. The AESO s role is to maintain safe, reliable and economic operation of the AIES. The AESO s planning responsibility includes determining the need for transmission system development and the manner in which that need is met. The AESO is also mandated to facilitate the interconnection of qualified market participants to the AIES. The AESO is regulated by the AUC and must apply to the AUC for approval of its NID. How is ATCO involved? ATCO is the transmission facilities owner (TFO) in the Fort McMurray area. While the AESO is responsible for identifying that transmission system development is needed, ATCO is responsible for detailed siting and routing, constructing, operating and maintaining the associated transmission facilities. The AESO has directed ATCO to provide information to stakeholders on this need and to file a facility proposal application with the AUC which will include a detailed description and location of the proposed transmission development.
