Review Panel published their 450-page Environmental Assessment Report endorsing the DGR project proposal on May 6, 2015. The Panel report, which was delivered to the Minister of the Environment, summarized the information received by the Panel, including comments from participants, and the Panel's conclusions related to the purpose, need and alternatives; design features and project development; waste management; effects on the natural environment; effects on human health and safety; malfunctions, accidents, and malevolent acts; social and economic aspects; Aboriginal interests, rights, and title; post-closure safety case; Lake Huron and the Great Lakes; and cumulative effects. The Panel concluded that the project was not likely to cause significant adverse environmental effects, taking into account the implementation of the mitigation measures committed to by OPG together with the mitigation measures recommended by the Panel. Request for Additional Information, 2016 On February 18, 2016, The Minister of Environment and Climate Change, the Honourable Catherine McKenna, requested additional information and further studies from OPG on the environmental assessment for the proposed DGR project. This came after the submission of the Joint Review Panel Environmental Assessment Report approving the project. The Panel requested that OPG provide additional information on three aspects of the project: (1) alternate locations for the project, (2) cumulative environmental effects of the project, and (3) an updated list of mitigation commitments for each identified adverse effect under the CEAA 2012. In requesting additional information from OPG concerning alternate locations, Minister Catherine McKenna requested "a study that details the environmental effects of technically and economically feasible alternate locations for the project, with specific reference to actual locations that would meet Ontario Power Generation’s criteria for technically and economically feasible" In a response letter from OPG dated April 15, 2016, OPG outlined their interpretation of Minister McKenna's request for additional information. OPG stated that they intended to provide an assessment of the environmental effects of two technically and economically feasible geologic regions in Ontario for a new L&ILW disposal facility. This included one assessment to consider a DGR located in a sedimentary rock formation located in Southern Ontario, and one assessment to consider a DGR located in a granite rock formation in central to northern Ontario. On December 28, 2016, OPG submitted their response to the request for additional information issued by Minister McKenna. In the submission, OPG applied the criteria of technical and economic feasibility to the entire province of Ontario, and
