(OPG) currently holds the Nuclear Power Reactor Site Preparation Licence (PRSL) 18.00/2022 (hereinafter “the Licence”) to prepare the site for the future construction and operation of a new Nuclear Generating Station (hereinafter “the new nuclear facility”) at Darlington New Nuclear Project (DNNP) site located in the Municipality of Clarington, in the regional municipality of Durham, in the province of Ontario. The Licence is valid from August 17, 2012 to August 17, 2022 and allows OPG to conduct the following site preparation activities for the future new nuclear facility: a) Construction of access control measures; b) Clearing and grubbing of vegetation; c) Excavation and grading of the site; d) Installation of services and utilities; e) Construction of administrative and physical support facilities inside future protected area; f) Construction of environmental monitoring and mitigation systems; and g) Construction of flood protection and erosion control measures. In 2013, the Government of Ontario deferred the construction of the new nuclear facility at DNNP site but requested OPG to maintain the Licence. To date, OPG has not received further direction to proceed with the project, hence none of the site preparation activities, listed above, have been carried out and no Engineering Procurement and Construction Company (EPC Co.) has been contracted. Licence Condition 4.3 of the Licence requires OPG to submit an annual report to the Canadian Nuclear Safety Commission (CNSC) on the licenced activities and information as listed in Section 3.4.3 of the Licence Conditions Handbook. This 2019 Annual Report for DNNP fulfills the above requirement for the reporting period from March 1, 2019 to March 1, 2020. Highlights of performance and activities associated with the Licence for the reporting period include: No reportable events related to security, fire and emergency, occupational health and safety, and environmental excursion. The DNNP Commitments Report was updated, the revision R003, has been accepted by the CNSC (Reference 1). Progress on the following long lead time commitments continue to advance: o Mitigation measures for the potential loss of Bank Swallow nesting habitat (commitments D-P-3.8 and D-P-12.5): Bank Swallow monitoring studies continued in the reporting period. OPG has removed the earthen mound artificial Bank Swallow nesting habitat at the DNNP site following six N-TMP-10010-R012 (Microsoft® 2016) OPG Proprietary Document Number: Usage Classification: Report NK054-REP-01210-00115 N/A Sheet Number: Revision Number: Page: R001 6 of 20 Title: 2019 DARLINGTON NEW NUCLEAR PROJECT ANNUAL REPORT consecutive years of Bank Swallows nesting absence. OPG continues to explore other artificial nesting structure options. o Deep Water Aquatic and Fish Community Characterization (Commitment D- C-1.2). The 2019 characterization reconfirmed the 2018 study conclusion that having the intake and diffuser at depths beyond 15 meters does not appear to be advantageous with respect to reducing potential fish impingement. This conclusion stands. Similarly, it also concluded that siting of the intake and diffuser at depths beyond 15 meters does not appear to be advantageous with respect to reducing potential fish entrainment. o Baseline Updates (Commitments D-P-12.3 to D-P-12.6): Sediment and surface water sampling, adult fish community surveys, Least Bittern and Bobolink surveys and base flow monitoring at Darlington Creek were conducted to support the future completion of deliverable of their respective
