(Golder) was retained by Capital Power Corporation (Capital Power) to prepare a Post- Construction Monitoring and Mitigation Plan (PCMMP) for their proposed Halkirk 2 Wind Power Project (the Project) located within the County of Paintearth and Flagstaff County, approximately 12 kilometres (km) northeast of Halkirk, Alberta. The Project is located within portions of Townships 39 and 40, Ranges 13, 14 and 15, W4M (Figure 1). The Project will consist of 74 Vestas V110 2.0 megawatt (MW) wind turbines, for a total installed nameplate capacity of 148 MW. The project will also include access roads, an underground electrical collector system, and a substation. The PCMMP describes the proposed post construction monitoring activities and mitigation measures Capital Power proposes to implement during construction and operation of the Project and focuses on understanding direct impacts to birds and bats over a three-year period, as detailed within the following sections. The PCMMP accompanies the submission of the Environmental Evaluation, as per requirements identified in The Approach section of the updated Alberta Environment and Parks (AEP) Wildlife Directive for Alberta Wind Energy Projects (the Directive), dated January 27, 2017 (AEP 2017). Ultimately, the Environmental Evaluation will support Capital Power’s application to the Alberta Utilities Commission (AUC) for a permit to construct and a licence to operate the Project. This PCMMP follows the recommendations outlined in the Directive, the Canadian Wildlife Service’s (CWS’s) Wind Turbines and Birds: A Guidance Document for Environmental Assessment (CWS 2007a), and the Recommended Protocols for Monitoring Impacts of Wind Turbines on Birds (CWS 2007b).

The post-construction monitoring program will assess the effectiveness of mitigation efforts and determine whether additional or modified mitigation measures are warranted. Post-construction monitoring for the Project will be carried out during the first three years of Project operation, and will consist of the following: duplication of select pre-construction wildlife inventory surveys; weekly bird and bat mortality searches at one-third of the turbines (25 of the 74 turbines), between March 1 and October 30. The same plots will be used for both bird and bat mortality searches; three searcher efficiency trials each season (i.e., spring, summer and fall) for each search technician; three scavenger impact trials, equally spaced out (i.e., early, middle and late), during each season; and
