Part 1 - Key Considerations

1. Introduction

The purpose of this document is to identify for the proponent the minimum information requirements for the preparation of an Environmental Impact Statement (EIS) for a designated project [1] to be assessed pursuant to the Canadian Environmental Assessment Act, 2012 (CEAA 2012). This document specifies the nature, scope and extent of the information required. Part 1 of this document defines the scope of the environmental assessment (EA) and provides guidance and general instruction that must be taken into account in preparing the EIS. Part 2 outlines the information that must be included in the EIS.

Section 5 of CEAA 2012 describes the environmental effects that must be considered in an EA, including changes to the environment and effects of changes to the environment. The factors that are to be considered in an EA are described under section 19 of CEAA 2012. The Canadian Environmental Assessment Agency (the Agency) or a review panel will use the proponent's EIS and other information received during the EA process to prepare a report that will inform the issuance of a decision statement by the Minister of Environment and Climate Change. Therefore the EIS must include a full description of the changes the project will cause to the environment that may result in adverse effects on areas of federal jurisdiction (i.e. section 5 of CEAA 2012) including changes that are directly linked or necessarily incidental to any federal decisions that would permit the project to be carried out. The EIS must also include a list of key mitigation measures that the proponent proposes to undertake in order to avoid or minimize any adverse environmental effects of the project. It is the responsibility of the proponent to provide sufficient data and analysis on potential changes to the environment to ensure a thorough evaluation of the environmental effects of the project by the Agency or review panel.

2. Guiding Principles

2.1. Environmental assessment as a planning and decision making tool

Environmental assessment (EA) is a process to predict environmental effects of proposed projects before they are carried out. An EA:

  • identifies potential adverse environmental effects;
  • proposes measures to mitigate adverse environmental effects;
  • predicts whether there will be significant adverse environmental effects, after mitigation measures are implemented; and
  • includes a follow-up program to verify the accuracy of the EA and the effectiveness of the mitigation measures.

2.2. Public participation

One of the purposes identified in CEAA 2012 is to ensure that opportunities are provided for meaningful public participation during an EA. CEAA 2012 requires that the Agency provide the public with an opportunity to participate in the EA. For EAs led by the Agency the public has an opportunity to comment on the draft EA report. For EAs by a review panel, CEAA 2012 requires that the review panel hold a public hearing. Additional opportunities for participation may also be provided.

Meaningful public participation is best achieved when all parties have a clear understanding of the proposed project as early as possible in the review process. The proponent is required to provide current information about the project to the public and especially to the communities likely to be most affected by the project.

2.3. Engagement with Indigenous groups

A key objective of CEAA 2012 is to promote communication and cooperation with Indigenous peoples which includes First Nations, Inuit and Métis. The proponent is expected to engage with potentially affected groups, beginning as early as possible in the project planning process. The proponent shall provide potentially affected groups with opportunities to learn about the project and its potential effects and to make their concerns known about the project's potential effects and discuss measures to mitigate those effects. The proponent is strongly encouraged to work with each potentially affected group separately or together (should more than one group propose to engaged together), to establish an engagement approach. The proponent will make reasonable efforts to integrate Aboriginal traditional knowledge into the assessment of environmental effects and provide evidence of all efforts. For more information on incorporating Aboriginal traditional knowledge, refer to Part 1, Section 4.2.2 of these guidelines.

In order to fulfill the Crown's constitutional obligations to consult with potentially impacted groups, the Agency integrates its legal obligation for consultation and accommodation in the EA process. The information gathered by the proponent during its engagement with groups helps to contribute to the Crown's understanding of any potential adverse impacts on potential or established Aboriginal or treaty rights protected under section 35 of the Constitution Act, 1982 ("section 35 Aboriginal rights") including title and related interests, and the effectiveness of measures proposed to avoid or minimize those impacts.

2.4. Application of the precautionary approach

In documenting the analyses included in the EIS, the proponent will demonstrate that all aspects of the project have been examined and planned in a careful and precautionary manner in order to avoid significant adverse environmental effects.

3. Scope of the Environmental Assessment

3.1. Designated project

On July 4, 2017, Alamos Gold Inc., the proponent of the Lynn Lake Gold Project, provided a project description to the Agency. Based on this project description, the Agency has determined that an EA is required under CEAA 2012 and will include the construction, operation, decommissioning and abandonment of the following project components:

  • Open pits
  • Ore, low grade ore, waste rock, overburden, top soil stockpile/storage areas
  • Tailings management facility
  • Water management facilities (potable and process)
  • Central ore milling and processing plant
  • Explosive storage and manufacturing
  • Effluent treatment
  • Site clearing, earthmoving, leveling, drilling and blasting activities
  • Transportation corridor construction or improvement
  • Ore and concentrate transportation
  • Water supply (industrial and drinking)
  • Wastewater treatment
  • Power supply, including any new powerlines to the facility and related electrical supply infrastructure)
  • Borrow areas
  • Ancillary infrastructure (security, parking areas, mine truck and vehicle maintenance shops, administrative offices, warehouses, laboratories, and vehicle fueling and maintenance facilities)
  • On-site and off-site accommodations
  • Diversion channel adjustments

3.2. Factors to be considered

Scoping establishes the parameters of the EA and focuses the assessment on relevant issues and concerns. Part 2 of this document specifies the factors to be considered in the EA, including the factors listed in subsection 19(1) of CEAA 2012:

  • environmental effects of the project, including the environmental effects of malfunctions or accidents that may occur in connection with the project and any cumulative environmental effects that are likely to result from the project in combination with other physical activities that have been or will be carried out;
  • the significance of the effects referred to above;
  • comments from the public;
  • mitigation measures that are technically and economically feasible and that would mitigate any significant adverse environmental effects of the project;
  • the requirements of the follow-up program in respect of the project;
  • the purpose of the project;
  • alternative means of carrying out the project that are technically and economically feasible and the environmental effects of any such alternative means;
  • any change to the project that may be caused by the environment; and
  • the results of any relevant regional study pursuant to CEAA 2012.
3.2.1. Changes to the environment

Environmental effects occur as interactions between actions (the carrying out of the project or decisions made by the federal government in relation to the project) and receptors in the environment, and subsequently between components of the environment (e.g. change in water quality that may affect fish).

Under CEAA 2012, an examination of environmental effects that result from changes to the environment as a result of the project being carried out or as a result of the federal government exercising any power duty or function that would allow the project to be carried out must be considered in the EIS.

In scoping the potential changes to the environment that may occur, the proponent should consider any potential changes in the physical environment such as changes to air quality, water quality and quantity, and physical disturbance of land that could reasonably be expected to occur.

3.2.2. Valued components to be examined

Valued components (VCs) refer to environmental biophysical or human features that may be impacted by a project. The value of a component not only relates to its role in the ecosystem, but also to the value people place on it. For example, it may have been identified as having scientific, social, cultural, economic, historical, archaeological or aesthetic importance.

The proponent must conduct and focus its analysis on VCs as they relate to section 5 of CEAA 2012, including the ones identified in Section 6.2 (Part 2) of these guidelines that may be affected by changes in the environment, as well as species at risk and their critical habitat as per the requirement outlined in section 79 of the Species at Risk Act. Section 5 of CEAA 2012 defines environmental effects as:

  • a change that may be caused to fish and fish habitat, marine plant and migratory birds;
  • a change that may be caused to the environment on federal lands, in another province or outside Canada;
  • with respect to Aboriginal peoples, an effect of any change that may be caused to the environment on:
    • health and socio-economic conditions;
    • physical and cultural heritage;
    • the current use of lands and resources for traditional purposes; or
    • any structure, site or thing that is of historical, archaeological, paleontological or architectural significance.
  • for projects requiring a federal authority to exercise a power or perform a duty or function under another Act of Parliament:
    • a change, other than the ones mentioned above, that may be caused to the environment and that is directly linked or necessarily incidental to the exercise of the federal power or the performance of a duty or function; and
    • the effect of that change, other than the effects mentioned above, on:
      • health and socio-economic conditions,
      • physical and cultural heritage, or
      • any structure, site or thing that is of historical, archaeological, paleontological or architectural significance.

The list of VCs presented in the EIS will be completed according to the evolution and design of the project and reflect the knowledge acquired through public consultation and engagement with Indigenous groups. The EIS will describe what methods were used to predict and assess the adverse environmental effects of the project on these valued components.

The VCs will be described in sufficient detail to allow the reviewer to understand their importance and to assess the potential for environmental effects arising from the project activities. The EIS will provide a rationale for selecting specific VCs and for excluding any VCs or information specified in these guidelines. Challenges may arise regarding particular exclusions, so it is important to document the information and the criteria used to justify the exclusion of a particular VC or piece of information. Justification may be based on, for example, primary data collection, computer modelling, literature references, public participation or engagement with Indigenous groups, or expert input or professional judgement. The EIS will identify those VCs, processes, and interactions that either were identified to be of concern during any workshops or meetings held by the proponent or that the proponent considers likely to be affected by the project. In doing so, the EIS will indicate to whom these concerns are important (i.e. the public or Indigenous groups) and the reasons why, including environmental, cultural, historical, social, economic, recreational, and aesthetic considerations, and traditional knowledge. If comments are received on a component that has not been included as a VC, these comments will be summarized and the rationale for excluding the component will address the comments.

3.2.3. Spatial and temporal boundaries

The spatial and temporal boundaries used in the EA may vary depending on the VC and will be considered separately for each VC, including for VCs related to the current use of lands and resources for traditional purposes by Aboriginal peoples, or other environmental effects referred to under paragraph 5(1)(c) of CEAA 2012. The proponent is encouraged to consult with the Agency, federal and provincial government departments and agencies, local government and Indigenous groups, and take into account public comments when defining the spatial and temporal boundaries used in the EIS.

The EIS will describe the spatial boundaries, including local and regional study areas, of each VC to be used in assessing the potential adverse environmental effects of the project and provide a rationale for each boundary. Spatial boundaries will be defined taking into account the appropriate scale and spatial extent of potential environmental effects, community knowledge and Aboriginal traditional knowledge, current or traditional land and resource use by Indigenous groups, ecological, technical, social and cultural considerations.

The temporal boundaries of the EA will span all phases of the project determined to be within the scope of this EA as specified under section 3.1 above. Temporal boundaries will be defined taking into account effects predicated after project decommissioning and reclamation, and community knowledge and Aboriginal traditional knowledge. If impacts are predicted after project decommissioning, this should be taken into consideration in defining boundaries. Community knowledge and aboriginal traditional knowledge should factor into decisions around defining temporal boundaries.

If the temporal boundaries do not span all phases of the project, the EIS will identify the boundaries used and provide a rationale.

4. Preparation and Presentation of the Environmental Impact Statement

4.1. Guidance

The proponent is encouraged to consult relevant Agency policy and guidance [2] on topics to be addressed in the EIS, and to liaise with the Agency during the planning and development of the EIS. The proponent is also encouraged to consult relevant guidance from other federal departments.

In planning for a mine proposal and in developing the EIS and technical support documentation, the proponent is advised to consider the "Environmental Code of Practice for Metal Mines" [3], published by Environment and Climate Change Canada in 2009. The recommended practices in the Code include the development and implementation of environmental management tools, the management of wastewater and mining wastes, and the prevention and control of environmental releases to air, water and land. In addition, the parameters and approach of the Environmental Effects Monitoring program under the Metal Mining Effluent Regulations (MMER) should be considered when developing a baseline monitoring program for the aquatic environment.

For projects requiring the use of natural water bodies frequented by fish for the disposal of mine waste, including tailings and waste rock and for the management of process water, the MMER would need to be amended to add the affected water bodies to Schedule 2 to designate them as tailings impoundment areas. This regulatory process will not be initiated until a detailed assessment of alternatives for mine waste disposal has been undertaken by the proponent. Conducting this robust and thorough assessment of alternatives during the EA will streamline the overall regulatory review process and minimize the time required to proceed with the MMER amendment process. It also facilitates a thorough and transparent review of the assessment of alternatives as part of the EA process. For further guidance, the proponent should consult Environment and Climate Change Canada's Guidelines for the Assessment of Alternatives for Mine Waste Disposal (2011).

In the event that the proponent chooses not to conduct an assessment of alternatives for mine waste disposal during the EA stage pursuant to the MMER requirements, the EA under CEAA 2012 will continue. In these circumstances, the proponent should discuss with Environment and Climate Change Canada how the information requirements and consultation associated with the MMER amendment process can be addressed through other means.

Submission of regulatory and technical information necessary for federal authorities to make their regulatory decisions during the conduct of the EA is at the discretion of the proponent. Although that information is not necessary for the EA decision, the proponent is encouraged to submit it concurrent with the EIS. While the EIS must outline applicable federal authorizations required for the project to proceed, the proponent must provide information relevant to the regulatory role of the federal government. It should be noted that the issuance of these other applicable federal legislative, regulatory and constitutional requirements are within the purview of the relevant federal authorities, and are subject to separate processes post EA decision.

4.2. Use of information

4.2.1. Government expert advice

Section 20 of CEAA 2012 requires that every federal authority with specialist or expert information or knowledge with respect to a project subject to an EA must make that information or knowledge available to the Agency or the review panel. The Agency will advise the proponent of the availability of pertinent information or knowledge or expert and specialist knowledge received from other federal authorities or other levels of government so that it can be incorporated into the EIS.

4.2.2. Community knowledge and Aboriginal traditional knowledge

Sub-section 19(3) of CEAA 2012 states that "the environmental assessment of a designated project may take into account community knowledge and Aboriginal traditional knowledge". For the purposes of these guidelines, community knowledge and Aboriginal traditional knowledge are types of knowledge acquired and accumulated by a local community or an Indigenous group.

The proponent will incorporate into the EIS the community knowledge and Aboriginal traditional knowledge to which it has access or that is acquired through public participation and engagement with Indigenous groups, in keeping with appropriate ethical standards and obligations of confidentiality. Community knowledge and Aboriginal traditional knowledge should be reported as separate types of knowledge in the EIS. The proponent should verify Aboriginal traditional knowledge in the EIS with the affected Indigenous group. The proponent will integrate Aboriginal traditional knowledge into all aspects of its assessment including both methodology (e.g. establishing spatial and temporal boundaries, defining significance criteria) and analysis (e.g. baseline characterization, effects prediction, development of mitigation measures, conducting a Human Health Risk Assessment). Agreement should be obtained from Indigenous groups regarding the use, management and protection of their existing traditional knowledge information during and after the EA. Where existing, the proponent should apply available Indigenous' group written policy or protocol for the collection and sharing of Aboriginal traditional knowledge. If policies or protocols for the collection and sharing of Aboriginal traditional knowledge are not available, the proponent should undertake appropriate practices. For more information on how Aboriginal traditional knowledge can be obtained and incorporated in the preparation of the EIS, please refer to the Agency's reference guide entitled "Considering Aboriginal traditional knowledge in environmental assessments conducted under the Canadian Environmental Assessment Act, 2012 ".

4.2.3. Existing information

In preparing the EIS, the proponent should consider existing information and previously completed studies relevant to the project, including pre-development, development, closure, reclamation, and post-closure monitoring studies related to the previous construction and operations of mines at the Gordon and MacLellan sites and all their associated developments. When relying on existing information to meet requirements of the EIS Guidelines, the proponent will either include the information directly in the EIS or clearly direct the reader to where it may obtain the information (i.e. through cross-referencing). When relying on existing information, the proponent will also comment on how the data were applied to the project, separate factual lines of evidence from inference, and state any limitations on the inferences or conclusions that can be drawn from the existing information.

4.2.4. Confidential information

In implementing CEAA 2012, the Agency is committed to promoting public participation in the EA of projects and providing access to the information on which EAs are based. All documents prepared or submitted by the proponent or any other stakeholder in relation to the EA are included in the Canadian Environmental Assessment Registry and made available to the public on request. For this reason, the EIS will not contain information that:

  • is sensitive or confidential (i.e. financial, commercial, scientific, technical, personal, cultural or other nature), that is treated consistently as confidential, and the person affected has not consented to the disclosure; or
  • may cause substantial harm to a person or specific harm to the environment through its disclosure.

The proponent will consult with the Agency regarding whether specific information requested by these guidelines should be treated as confidential.

4.3. Study strategy and methodology

The proponent is expected to respect the intent of these guidelines and to consider the environmental effects that are likely to arise from the project (including situations not explicitly identified in these guidelines), the technically and economically feasible mitigation measures that will be applied, and the significance of any residual effects. Except where specified by the Agency, the proponent has the discretion to select the most appropriate methods to compile and present data, information and analysis in the EIS as long as they are justifiable and replicable.

It is possible these guidelines may include matters which, in the judgement of the proponent, are not relevant or significant to the project. If such matters are omitted from the EIS, the proponent will clearly indicate it, and provide a justification so the Agency, federal authorities, Indigenous groups, the public and any other interested party have an opportunity to comment on this decision. Where the Agency or the review panel disagrees with the proponent's decision, it will require the proponent to provide the specified information.

The assessment will include the following general steps:

  • identifying the activities and components of the project;
  • predicting potential changes to the environment;
  • predicting and evaluating the likely effects on identified VCs;
  • identifying technically and economically feasible mitigation measures for any significant adverse environmental effects;
  • determining any residual environmental effects;
  • considering cumulative effects of the project in combination with other physical activities that have been or will be carried out; and
  • determining the potential significance of any residual environmental effect following the implementation of mitigation measures.

For each VC, the EIS will describe the methodology used to assess project-related effects. The EIS could include an analysis of the pathway of the effects of environmental changes on each VC. The EIS will document where and how scientific, engineering, community knowledge and Aboriginal traditional knowledge were used to reach conclusions. Assumptions will be clearly identified and justified. All data, models and studies will be documented such that the analyses are transparent and reproducible. All data collection methods will be specified. The uncertainty, reliability, sensitivity and conservativeness of models used to reach conclusions must be indicated.

The EIS will identify all significant gaps in knowledge and understanding related to key conclusions, and the steps to be taken by the proponent to address these gaps. Where the conclusions drawn from scientific, engineering and technical knowledge are inconsistent with the conclusions drawn from Aboriginal traditional knowledge, the EIS will present each perspective on the issue (including documentation of Indigenous groups' input) and a statement of the proponent's conclusions.

The EIS will include a description of the environment (both biophysical and human), including the components of the existing environment and environmental processes, their interrelations as well as the variability in these components, processes and interactions over time scales appropriate to the likely effects of the project. The description will include scientific and Aboriginal traditional knowledge and be sufficiently detailed to characterize the environment before any disturbances to the environment due to the project and to identify, assess and determine the significance of the potential adverse environmental effects of the project. These data should include results from studies done prior to any physical disruption of the environment due to initial site clearing activities. The information describing the existing environment may be provided in a stand-alone chapter of the EIS or may be integrated into clearly defined sections within the effects assessment of each VC. This analysis will include environmental conditions resulting from historical (e.g. previous mining) and present activities in the local and regional study areas.

If the baseline data have been extrapolated or otherwise manipulated to depict environmental conditions in the study areas, modelling methods and equations will be described and will include calculations of margins of error and other relevant statistical information, such as confidence intervals and possible sources of error. The proponent will provide the references used in creating their approach to baseline data gathering, including identifying where appropriate, the relevant federal or provincial standards. The proponent is encouraged to discuss the timeframe and considerations for its proposed baseline data with the Agency and affected Indigenous groups prior to submitting its EIS.

In describing and assessing effects to the physical and biological environment, the proponent will take an ecosystem approach that considers both scientific and community knowledge and Aboriginal traditional knowledge and perspectives regarding ecosystem health and integrity. The proponent will consider the resilience of relevant species populations, communities and their habitats.

The assessment of environmental effects on Aboriginal peoples, pursuant to paragraph 5(1)(c) of CEAA 2012, will undergo the same rigour and type of assessment as any other VC (including setting of spatial and temporal boundaries, identification and analysis of effects, identification of mitigation measures, determination of residual effects, identification and a clear explanation of the methodology used for assessing the significance of residual effects and assessment of cumulative effects). The proponent will consider the use of both primary and secondary sources of information regarding baseline information, changes to the environment and the corresponding effect on health, socio-economics, physical and cultural heritage and the current use of lands and resources for traditional purposes. Primary sources of information include traditional land use studies, socio-economic studies, heritage surveys or other relevant studies conducted specifically for the project and its EIS. Often these studies and other types of relevant information are obtained directly from Indigenous groups. Secondary sources of information include previously documented information on the area, not collected specifically for the purposes of the project, or desk-top or literature-based information.

The proponent will provide Indigenous groups reasonable opportunity to review and provide comments on the information used for describing and assessing effects on Aboriginal peoples, prior to submitting the EIS (further information on engaging with Indigenous groups is provided in Part 2, Section 5 of this document). Where there are discrepancies in the views of the proponent and Indigenous groups on the information to be used in the EIS, the EIS will document these discrepancies and the rationale for the proponent's selection of information.

The assessment of the effects of each of the project components and physical activities, in all phases, will be based on a comparison of the biophysical and human environments between the predicted future conditions with the project and the predicted future conditions without the project. In undertaking the environmental effects assessment, the proponent will use best available information and methods. All conclusions will be substantiated and predictions will be based on clearly stated assumptions. The proponent will describe how each assumption has been tested. With respect to quantitative models and predictions, the EIS will document the assumptions that underlie the model, the quality of the data and the degree of certainty of the predictions obtained. For all predictions related to effects on Indigenous groups, the proponent will document Indigenous group involvement.

4.4. Presentation and organization of the environmental impact statement

To facilitate the identification of the documents submitted and their placement in the Canadian Environmental Assessment Registry, the title page of the EIS and its related documents will contain the following information:

  • project name and location;
  • title of the document, including the term "environmental impact statement";
  • subtitle of the document;
  • name of the proponent; and
  • date of submission of the EIS.

The EIS will be written in clear, precise language. A glossary defining technical words, acronyms and abbreviations will be included. The EIS will include charts, diagrams, tables, maps and photographs, where appropriate, to clarify the text. Perspective drawings that clearly convey the various components of the project will also be provided. Wherever possible, maps will be presented in common scales and datum to allow for comparison and overlay of mapped features.

For purposes of brevity and to avoid repetition, cross-referencing is preferred. The EIS may make reference to the information that has already been presented in other sections of the document, rather than repeating it. Detailed studies (including all relevant and supporting data and methodologies) will be provided in separate appendices and will be referenced by appendix, section and page in the text of the main document. The EIS will explain how information is organized in the document. This will include a table of content with a list of all tables, figures, and photographs referenced in the text. A complete list of supporting literature and references will also be provided. A table of concordance, which cross references the information presented in the EIS with the information requirements identified in the EIS Guidelines, will be provided. The proponent will provide copies of the EIS and its summary for distribution, including paper and electronic version in an unlocked, searchable PDF format, as directed by the Agency.

4.5. Summary of the environmental impact statement

The proponent will prepare a summary of the EIS in both of Canada's official languages (French and English) to be provided to the Agency at the same time as the EIS that will include the followings:

  • a concise description of all key components of the project and related activities;
  • a summary of the engagement with Indigenous groups, as verified by each group, and the participation of the public and government agencies, including a summary of the issues raised and the proponent's responses;
  • an overview of expected changes to the environment;
  • an overview of the key environmental effects of the project, as described under section 5 of CEAA 2012, and proposed technically and economically feasible mitigation measures;
  • an overview of how factors under paragraph 19(1) of CEAA 2012 were considered;
  • the proponent's conclusions on the residual environmental effects of the project, and the significance of those effects, after taking into account the mitigation measures.

The summary is to be provided as a separate document and should be structured as follows:

  1. Introduction and EA context
  2. Project overview
  3. Alternative means of carrying out the project
  4. Public participation
  5. Engagement with Indigenous Groups
  6. Summary of environmental effects assessment for each valued component, including:
    1. description of the baseline
    2. anticipated changes to the environment
    3. anticipated effects
    4. mitigation measures
    5. significance of residual effects
  7. Follow-up and monitoring programs proposed

The summary will have sufficient details for the reader to understand the project, any potential environmental effects, proposed mitigation measures, and the significance of the residual effects. The summary will include key maps illustrating the project location and key project components.

Part 2 – Content of the Environmental Impact Statement

1. Introduction and Overview

1.1. The proponent

In the EIS, the proponent will:

  • provide contact information (e.g. name, address, phone, fax, email);
  • identify itself and the name of the legal entity(ies) that would develop, manage and operate the project;
  • describe corporate and management structures;
  • specify the mechanism used to ensure that corporate policies will be implemented and respected for the project; and
  • identify key personnel, contractors, and/or sub-contractors responsible for preparing each section of the EIS.

1.2. Project Overview

The EIS will describe the project, key project components and associated activities, scheduling details, the timing of each phase of the project and other key features. If the project is part of a larger sequence of projects, the EIS will outline the larger context.

The overview is to identify the key components of the project, rather than providing a detailed description, which will follow in Part 2, Section 3 of this document.

1.3. Project Location

The EIS will contain a description of the geographical setting in which the project will take place. This description will focus on those aspects of the project and its setting that are important in order to understand the potential environmental effects of the project. The following information will be included:

  • the Universal Transverse Mercator (UTM) projection coordinates of the main project site;
  • current land use in the area;
  • distance of the project facilities and components to any federal lands;
  • the environmental significance and value of the geographical setting in which the project will take place and the surrounding area;
  • environmentally sensitive areas, such as national, provincial and regional parks, ecological reserves, wetlands, estuaries, and habitats of federally or provincially listed species at risk and other sensitive areas;
  • description of local communities; and
  • traditional territories and/or consultation areas, treaty lands, Indian Reserve lands and Métis harvesting regions, locals, and/or settlements (seasonal or permanent);
  • traditional and commercial land uses by Indigenous peoples and the significance of the geographical setting to their culture and rights-based practices and role in their cultural landscape.

1.4. Regulatory framework and the role of government

The EIS will identify:

  • any federal power, duty or function that may be exercised that would permit the carrying out (in whole or in part) of the project or associated activities;
  • legislation and other regulatory approvals that are applicable to the project at the federal, provincial, regional and municipal levels;
  • government policies, resource management plans, planning or study initiatives pertinent to the project and/or EA and their implications;
  • any treaty, self-government or other agreements between federal or provincial governments and Indigenous groups that are pertinent to the project and/or EA;
  • any relevant land use plans, land zoning, or community plans (including Indigenous plans); and
  • regional, provincial and/or national objectives, standards or guidelines that have been used by the proponent to assist in the evaluation of any predicted environmental effects.

2. Project Justification and Alternatives Considered

2.1. Purpose of the project

The EIS will describe the purpose of the project by providing the rationale for the project, explaining the background, the problems or opportunities that the project is intended to satisfy and the stated objectives from the perspective of the proponent. If the objectives of the project are related to broader private or public sector policies, plans or programs, this information will also be included.

The EIS will also describe the predicted environmental, economic and social benefits of the project. This information will be considered in assessing the justifiability [4] of any significant adverse residual environmental effects as defined in section 5 of CEAA 2012, if such effects are identified.

2.2. Alternative means of carrying out the project

The EIS will identify and consider the environmental effects of alternative means of carrying out the project that are technically and economically feasible. The proponent will complete the assessment of alternative means in accordance with the Agency's Operational Policy Statement entitled "Addressing "Purpose of" and "Alternative Means" under the Canadian Environmental Assessment Act, 2012".

In its alternative means analysis, the proponent will address, at a minimum, the following project components:

  • ore and concentrate transportation (means and routing considered);
  • access to the project site;
  • location of key project components (open pits, pipelines; explosives storage; tailings management facility; central ore milling and processing plant (including consideration of a processing facility at each mining site) ore, low grade ore, waste rock, overburden, top soil stockpiles/storage areas; etc.);
  • ore processing methods/technologies;
  • fuel storage and distribution;
  • power supply;
  • management of water supply and waste water;
  • water management and location of the final effluent discharge points;
  • workforce accommodations and transportation;
  • diversion channel adjustments; and
  • mine waste disposal and final effluent discharge (methods and sites considered) [5].

The Agency recognizes that projects may be in the early planning stages when the EIS is being prepared. Where the proponent has not made final decisions concerning the placement of project infrastructure, the technologies to be used, or that several options may exist for various project components, the proponent shall conduct an environmental effects analysis at the same level of detail for each of the various options available (alternative means) within the EIS.

3. Project Description

It will provide a description of efforts made to distribute project information and provide a description of information and materials that were distributed during the consultation process. The EIS will indicate the methods used, where the consultation was held, the persons and organizations consulted, the concerns voiced and the extent to which this information was incorporated in the design of the project as well as in the EIS. The EIS will provide a summary of key issues raised related to the project and its potential effects to the environment as well as describe any outstanding issues and ways to address them.

5. Engagement With Indigenous Groups and Concerns Raised

For the purposes of developing the EIS, the proponent will engage with Indigenous groups that may be affected by the project, to obtain and incorporate their views on:

  • effects of changes to the environment on Aboriginal peoples (health and socio-economic conditions; physical and cultural heritage, including any structure, site or thing that is of historical, archaeological, paleontological or architectural significance; and current use of lands and resources for traditional purposes) pursuant to paragraph 5(1)(c) of CEAA 2012, and
  • potential adverse impacts of the project on potential or established section 35 rights, including title and related interests, in respect of the Crown's duty to consult, and where appropriate, accommodate Aboriginal peoples.

With respect to the effects of changes to the environment on Aboriginal peoples, the assessment requirements are outlined in Part 2, sections 6.1.9 and 6.3.4 of these guidelines. With respect to potential adverse impacts of the project on potential or established section 35 rights, including title and related interests, the EIS will document for each group identified in Part 2, Section 5.1 of these guidelines (or in subsequent correspondence from the Agency):

  • potential or established section 35 rights [6], including title and related interests, when this information is directly provided by a group to the proponent, the Agency or is available through public records, including:
    • geographical extent, nature, frequency and timing of the practice or exercise of the right; and
    • maps and data sets (e.g., fish catch numbers);
  • characterization of changes to date on potential or established section 35 rights;
  • potential adverse impacts of each of the project components and physical activities, in all phases, on potential or established section 35 rights, including title and related interests. This assessment is to be based on a comparison of the exercise of the identified rights, title and related interests between the predicted future conditions with the project and the predicted future conditions without the project. Include the perspectives of potentially impacted groups and document Indigenous groups' involvement;
  • measures identified to accommodate potential adverse impacts of the project on the potential or established section 35 rights, including title and related interests. These measures will be written as specific commitments that clearly describe how the proponent intends to implement them, and may go beyond mitigation measures that are developed to address potential adverse environmental effects;
  • potential adverse impacts on potential or established section 35 rights, including title and related interests that have not been fully mitigated or accommodated as part of the EA and associated engagement with Indigenous groups. The proponent will also take into account the potential adverse impacts that may result from the residual and cumulative environmental effects. Include the perspectives of potentially affected groups where these were provided to the proponent by the groups;
  • VCs suggested by Indigenous groups for inclusion in the EIS, whether they were included, and the rationale for any exclusions; and
  • specific suggestions raised by Indigenous groups for mitigating the effects of changes to the environment on Indigenous peoples or accommodating potential adverse impacts of the project on existing Aboriginal and Treaty rights.

The information sources, methodology and findings of the assessment of paragraph 5(1)(c) effects under CEAA 2012 may be used to inform the assessment of potential adverse impacts of the project on potential or established section 35 rights, including title and related interests. However, there may be distinctions between the adverse impacts on potential or established section 35 rights, including title and related interests and paragraph 5(1)(c) effects under CEAA 2012. The proponent will carefully consider the potential distinction between these two aspects and, where there are differences, will include the relevant information in its assessment.

In terms of gathering views from potentially affected groups with respect to both environmental effects of the project and the potential adverse impacts of the project on potential or established section 35 rights, including title and related interests, the EIS will document:

  • VCs and related spatial and temporal boundaries suggested by groups for inclusion in the EIS, whether they were included, and the rationale for any exclusions;
  • specific suggestions raised by each group for mitigating the effects of changes to the environment on Aboriginal peoples or accommodating potential adverse impacts of the project on potential or established section 35 rights, including title and related interests;
  • views expressed by each group on the effectiveness of the mitigation or accommodation measures;
  • from the proponent's perspective, any potential cultural, social and/or economic impacts or benefits to each group identified that may arise as a result of the project. Include the perspectives of potentially affected groups where these were provided to the proponent by the groups;
  • any other comments, specific issues and concerns raised by potentially affected groups and how they were responded to or addressed;
  • changes made to the project design and implementation directly as a result of discussions with potentially affected groups;
  • where and how Aboriginal traditional knowledge was incorporated into the environmental effects assessment (including methodology, baseline conditions and effects analysis for all VCs) and the consideration of potential adverse impacts on potential or established section 35 rights, including title and related interests, and related mitigation measures; and
  • any additional issues and concerns raised by potentially affected groups in relation to the environmental effects assessment and the potential adverse impacts of the project on potential or established section 35 rights, including title and related interests.

The EIS will include a tracking table of key issues raised by each group, including the concerns raised related to the project, proposed mitigation measures, and where appropriate, a reference to the proponent's analysis in the EIS. Information provided related to potential adverse impacts on potential or established section 35 rights will be considered by the Crown in meeting its common law duty to consult obligations as set out in the Updated Guidelines for Federal Officials to Fulfill the Duty to Consult (2011).

5.1. Indigenous groups and engagement activities

With respect to engagement activities, the EIS will document:

  • the engagement activities undertaken with each group prior to the submission of the EIS, including the date and means of engagement (e.g. meeting, mail, telephone);
  • any future planned engagement activities; and
  • how engagement activities by the proponent allowed groups to understand the project and evaluate its effects on their communities, activities, potential or established section 35 rights, including title and related interests.

In preparing the EIS, the proponent will ensure that groups have access to timely and relevant information on the project and how the project may adversely impact them. The proponent will structure its engagement activities to provide adequate time for groups to review and comment on the relevant information. Engagement activities are to be appropriate to the groups' needs, arranged through discussions with the groups and in keeping with established consultation protocols, where available. The EIS will describe all efforts, successful or not, taken to solicit the information required from groups to support the preparation of the EIS.

The proponent will ensure that views of groups are recorded and that groups are provided with opportunities to validate the interpretation of their views. The proponent will keep detailed tracking records of its engagement activities, recording all interactions with groups, the issues raised by each group and how the proponent addressed the concerns raised. The proponent will share these records with the Agency.

For the groups expected to be most affected by the project, the proponent is expected to strive towards developing a productive and constructive relationship based on on-going dialogue with the groups in order to support information gathering and the effects assessment. These groups include:

  • Marcel Colomb First Nation
  • Mathias Colomb Cree Nation
  • Nisichawayasihk Cree Nation
  • O-Pipon-Na-Piwin Cree Nation
  • Manitoba Metis Federation
  • Peter Ballantyne Cree Nation
  • Barren Lands First Nation

For the above groups, the proponent will strive to use primary data sources and hold face-to-face meetings to discuss concerns. The proponent will facilitate these meetings by making key EA summary documents (baseline studies, EIS, key findings, plain language summaries) accessible in advance. The proponent will ensure there are sufficient opportunities for individuals and groups to provide oral input in the language of their choice. Upon receipt, the proponent should consider translating information for these groups into the appropriate Indigenous languages(s) in order to facilitate engagement activities during the EA.

For groups that may also be affected by the project, but to a lesser degree, the proponent will ensure these groups are notified about key steps in the EIS development process and of opportunities to provide comments on key EA documents and/or information to be provided regarding their community. The proponent will still ensure these groups are reflected in the baseline information and assessment of potential effects or impacts in the EIS. These groups include:

  • Métis Nation – Saskatchewan Northern Region 1
  • Métis Nation – Saskatchewan Eastern Region 1
  • Hatchet Lake First Nation
  • Northlands Denesuline First Nation
  • Sayisi Dene First Nation
  • Pickerel Narrows Cree Nation

The groups referenced above may change as more is understood about the environmental effects of the project and/or if the project or its components change during the EA. The Agency reserves the right to alter the list of groups that the proponent will engage as additional information is gathered during the EA.

Upon receipt of knowledge or information of potential effects or adverse impacts to a group not listed above, the proponent shall provide that information to the Agency at the earliest opportunity.

6. Effects Assessment

6.1.9. Indigenous peoples

With respect to potential effects of changes to the environment caused by the project on Indigenous peoples and the related VCs, baseline information will be provided for each group identified in Section 5 (Part 2) of these guidelines (and any groups identified after these guidelines are finalized). Baseline information will describe and characterize the elements in paragraph 5(1)(c) of CEAA 2012 based on the spatial and temporal scope selected for the EA according to the factors outlined in Part 1, Section 3.3.3 of this document. Baseline information will also characterize the regional context of each of the elements of paragraph 5(1)(c) of CEAA 2012 to support the assessment of project related effects and cumulative effects. Baseline information will be sufficient to provide a comprehensive understanding of the current state of each VC.

Baseline information for current use of lands and resources for traditional purposes will focus on the traditional activity (including hunting, fishing, trapping, plant gathering, and cultural practices) and include a characterization of the attributes of the activity that may be affected by project-related changes to the environmental and socio-economic change. This includes not only identifying species of importance, but also assessing the quality and quantity of preferred traditional resources and locations, timing (e.g. seasonality, access restrictions, distance from community), ambient/sensory environment (e.g. noise, air quality, visual landscape, presence of others) and cultural environment (e.g. historical/generational connections, preferred areas). Specific aspects that will be considered include, but are not limited to:

  • cultural values associated with the area affected by the project and the traditional uses identified.

Baseline information for health [13] and socio-economic conditions will include the functioning and health of the socio-economic environment, encompassing a broad range of matters that affect communities in the study area in a way that recognizes interrelationships, system functions and vulnerabilities. Specific aspects that will be considered include:

  • sites or areas that are used by Indigenous people either for permanent residences or on a seasonal/temporary basis and the number of people that use each site or area identified;
  • drinking and recreational use water sources (permanent, seasonal, periodic, or temporary);
  • consumption of country foods (also known as traditional foods) including food that is trapped, fished, hunted, harvested or grown for subsistence or medicinal purposes, outside of the commercial food chain;
  • which country foods are consumed by which groups, how frequently, and where these country foods are harvested;
  • commercial activities (e.g. fishing, trapping, hunting, forestry, outfitting); and
  • recreational uses.

Baseline information for physical and cultural heritage [14] (including any site, structure or thing of archaeological, paleontological, historical or architectural significance) will consider all elements of cultural and historical importance to groups in the area and is not restricted to artifacts considered under provincial heritage legislative requirements. Specific aspects that will be considered include:

  • burial sites;
  • cultural landscapes;
  • sacred, ceremonial or culturally important places, objects or things; and
  • archaeological potential and/or artifact places.

Any other baseline information that supports the analysis of predicted effects of project-related changes to the environment on Indigenous peoples will be included as necessary. The EIS will also indicate how input from Indigenous groups, including Aboriginal traditional knowledge, was used in establishing the baseline conditions related to health and socio-economics, physical and cultural heritage and current use of lands and resources for traditional purposes.

Baseline information for the following species or habitats of particular importance to health and socio-economic conditions, physical and cultural heritage, or current use of lands and resources for traditional purposes should be provided, including:

  • areas of concentration of migratory animals, such as breeding, denning and/or wintering areas;
  • ungulates, furbearers, amphibians, small mammals, and their habitat;
  • existing or proposed protected areas, special management areas, Indigenous groups' management or priority areas, and conservation areas in the regional study area; and
  • key plant communities and animals, both terrestrial and aquatic, that are potentially affected by the project.
6.1.10. Other changes to the environment arising as a result of a federal decision or due to changes on federal lands, in another province or outside Canada

Should there be the potential for a change to the environment arising as a result of a federal decision(s), or on federal lands, lands in another province or lands outside Canada, the EIS will include baseline information on the environmental component likely to be affected (if this information is not already covered in other subsections of these guidelines). For example, if an authorization provided under the Fisheries Act was to result in the flooding of key wildlife habitat, baseline information should be provided on the wildlife species likely to be affected.

6.1.11. Human environment
  • the rural and urban settings likely to be affected by the project;
  • any federal lands, lands located outside the province or Canada that may be affected by the project;
  • the current use of land in the study area, including a description of hunting, recreational and commercial fishing, trapping, gathering, outdoor recreation, use of seasonal cabins, outfitters;
  • current use of all waterways and water bodies that will be directly affected by the project, including recreational uses, where available;
  • location of and proximity of any permanent, seasonal or temporary residences or camps;
  • health [15] and socio-economic conditions, including the socio-economic determinants of health, the functioning and health of the socio-economic environment, encompassing a broad range of matters that affect communities in the study area in a way that recognizes interrelationships, system functions and vulnerabilities (for example effects on sub-populations such as workers/job seekers and their families, youth, elders, women, service providers, economically marginalized members of the community, etc.); and
  • physical and cultural heritage, including structures, sites or things of historical, archaeological, paleontological or architectural significance.

6.2. Predicted changes to the physical environment

The EA will include a consideration of the predicted changes to the environment as a result of the project being carried out or as a result of any powers, duties or functions that are to be exercised by the federal government in relation to the project. These predicted changes to the environment are to be considered in relation to each phase of the project (construction, operation, decommissioning, and abandonment) and are to be described in terms of the magnitude, geographic extent, duration and frequency, and whether the environmental changes are reversible or irreversible. For each predicted change, the proponent will identify all sensory and observable change indicators (e.g. smells, noise, smoke) adopted as a result of traditional knowledge in relation to each VC. As changes to various parts of the physical environment, listed below, may be inter-related as part of an ecosystem, the EIS will explain and describe the connections between the changes described.

6.2.1. Changes to the atmospheric environment
  • changes in air quality (including sulfur oxides (SOx), nitrous oxides (NOx), total suspended particulates, fine particulates smaller than 2.5 microns (PM2.5), respirable particulates of less than 10 microns (PM10) and diesel particulates presented in concentration values comparable to guidelines (i.e. μg/m3));
    • justify dispersion modeling methods and include relevant input and output files.
  • an estimate of the direct greenhouse gas emissions associated with all phases of the project as well as any mitigation measures proposed to minimize greenhouse gas emissions. This information is to be presented by individual pollutant and should also be summarized in CO2 equivalent per year;

6.2.2. Changes to groundwater and surface water
  • changes to groundwater flow patterns, fluxes, and divides based on the results of groundwater flow modelling that incorporates changes related to mining;
  • changes to turbidity, oxygen level, water temperature, ice regime, water quality;
  • changes in surface water quality associated with any mine effluent releases or surface runoff;
  • changes to the hydrological and hydrometric conditions;
  • changes to groundwater recharge/discharge areas and any changes to groundwater infiltration areas;
  • changes to groundwater quality associated with storage or release of any mine effluents or drainage including surface runoff; and
  • changes to water quality attributed to acid rock drainage and metal leaching associated with the storage of waste rock, ore, low grade ore, tailings, overburden and potential construction material, including:
    • short term metal leaching properties;
    • longer term rates of acid generation (if any) and metal leaching;
    • estimates of the potential for mined materials (including waste rock, tailings and low grade ore) to be sources of acid rock drainage or metal leaching;
    • estimates of potential time to the onset of acid rock drainage or metal leaching;
    • quantity and quality of leachate/effluent from samples of tailings, waste rock, and ore;
    • quantity and quality of effluent to be released from the site into the receiving waters;
    • quality of humidity cell or column test liquid from acid rock testing;
    • sensitivity analysis to assess the effects of imperfect segregation of waste rock;
    • pit water chemistry during operation and decommissioning and abandonment (post-closure), and pit closure management measures (e.g. flooding). This will include geochemical modelling of pit water quality in the post-closure period; and
    • surface and seepage water quality from the waste rock dumps, tailings/waste rock impoundment facility, stockpiles and other infrastructure during operation and post-closure.
6.2.3. Changes to riparian, wetland and terrestrial environments
  • overall description of changes related to landscape disturbance;
  • changes to the habitat of migratory and non-migratory birds, with a distinction made between the two birds category, including losses, structural changes and fragmentation of riparian habitat of terrestrial environments and wetlands frequented by birds (types of cover, ecological unit of the area in terms of quality, quantity, diversity, distribution and functions);
  • changes to critical habitat for federally listed species at risk (Species at Risk Act) and/or important habitat for species designated by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) (for listing on Schedule 1 of the Species at Risk Act); and
  • changes to key habitat for species important to current use of lands and resources for traditional purposes.

6.3. Predicted effects on valued components

Based on the predicted changes to the environment identified in section 6.2, the proponent is to assess the environmental effects of the project on the following VCs. All interconnections between VCs and between changes to multiple VCs will be described:

6.3.1. Fish and fish habitat
  • the identification of any potential adverse effects to fish and fish habitat as defined in subsection 2(1) of the Fisheries Act, including the calculations of any potential habitat loss or alterations (temporary or permanent) in terms of surface areas (e.g. spawning grounds, fry-rearing areas, feeding), and in relation to watershed availability and significance. The assessment will include a consideration of:
    • the geomorphological changes and their effects on hydrodynamic conditions and fish habitats (e.g. modification of substrates, dynamic imbalance, silting of spawning beds);
    • the modifications of hydrological and hydrometric conditions on fish habitat and on the fish species' life cycle activities (e.g. reproduction, fry-rearing, movements);
    • potential effects on riparian areas that could affect aquatic biological resources and productivity taking into account any anticipated modifications to fish habitat;
    • changes to water and sediment quality identified in changes to groundwater and surface water, and their potential effects on fish and fish habitat;
    • any potential imbalances in the food web in relation to baseline conditions; and
    • effects on the primary and secondary productivity of water bodies and how mine-related effects may affect fish food sources.
  • the effects of changes to the aquatic environment, including those identified under changes to groundwater and surface water, on fish and their habitat, including:
    • the anticipated changes in the composition and characteristics of the populations of various fish species, including shellfish and forage fish;
    • any modifications in migration or local movements (upstream and downstream migration, and lateral movements) following the construction and operation of works (physical and hydraulic barriers);
    • any reduction in fish populations as a result of potential overfishing due to increased number of people in the project area;
    • any modifications and use of habitats by federally or provincially listed fish species;
  • a discussion of how project construction timing correlates to key fisheries windows for freshwater and anadromous species, and any potential effects resulting from overlapping periods;
  • a discussion of how vibration caused by blasting may affect fish behaviour, such as spawning or migrations; and
  • calculate any potential habitat offset/compensation works related to fish and fish habitat in terms of the amount of habitat being offset/compensated, as well as the spatial location of the offsetting/compensation habitat.
6.3.2. Migratory birds
  • direct and indirect adverse effects on migratory birds, including population level effects that could be caused by all project activities, including, but not limited to:
    • site preparation;
    • deposit of harmful substances in waters that are frequented by migratory birds (e.g. tailing impoundment area);
  • collision risk of migratory birds with any project infrastructure and vehicles; and
  • indirect effects caused by increased disturbance (e.g. noise, light, presence of workers), relative abundance movements, and losses or changes in migratory bird habitat, considering the critical breeding and migration periods for the birds.
6.3.3. Species at risk
  • the potential adverse effects of the project on Species at Risk Act listed species and, where appropriate, its critical habitat; i.e. direct and indirect effects on the survival or recovery of Species at Risk Act listed species (e.g. common nighthawk, olive-sided flycatcher, rusty blackbird, yellow rail, short-eared owl, horned grebe, little brown myotis, northern myotis, northern leopard frog, and boreal woodland caribou).
  • the potential adverse effects of the project on species assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as extirpated, endangered, threatened, or of special concern (e.g. barren ground caribou, wolverine, bank swallow, and barn swallow).
6.3.4. Indigenous peoples

With respect to Indigenous peoples, a description and analysis for each group of how changes to the environment caused by the project will affect the following activities exercised by each Indigenous group:

  • current use of lands and resources for traditional purposes. This assessment will characterize the effects (including cumulative effects) on the use or activity (e.g. hunting, fishing, trapping, plant gathering, and cultural practices) as a result of the underlying changes to the environment (i.e. how will the activity change if the project proceeds). The underlying changes to the environment will also be described, including, but not limited to:
    • any changes to the availability or quality of resources (fish, wildlife, birds, plants or other natural resources) used for traditional purposes (e.g. hunting, fishing, trapping, collection of medicinal plants, use of sacred sites);
    • any changes to access and perceived access into areas used for traditional purposes, including development of new roads, deactivation or reclamation of access roads and changes to waterways that affect navigation, and how this may affect continued knowledge of the area, financial capacity to access and desirability to access;
    • any changes to the environment that affect cultural value or importance associated with traditional uses or areas affected by the project (e.g. values or attributes of the area that make it important as a place for inter-generational teaching of language or traditional practices, communal gatherings, integrity of preferred traditional practice areas);
    • how timing of project activities (e.g. construction, blasting, discharges) have the potential to interact with the timing of traditional practices, and any potential effects resulting from overlapping periods;
    • consideration of the regional context for traditional use, and the value of the project area in that regional context, including alienation of lands from traditional use;
    • any changes to environmental quality (e.g. air, water, soil), the sensory environment (e.g. noise, light, visual landscape);
    • consideration of sacred, ceremonial or culturally important places, objects or things;
    • any changes that could detract from use of the area or lead to avoidance of the area as a result of real and perceived disturbance of the environment (e.g. observation of and fear of contamination of water or country foods);
    • any changes to the environment resulting from the presence of worker or increased access to the area by non-Indigenous peoples (e.g. noise, competition for or pressure on resources);
    • an assessment of the potential to return affected areas to pre-project conditions to support traditional practices (including the identification of end land use goals);
  • human health, focusing on effects on health outcomes or risks in consideration of, but not limited to, potential changes in air quality, noise exposure and effects of vibration from blasting, current and future availability of country foods, and water quality (drinking, recreational and cultural uses). When risks to human health due to changes in one or more of these components are predicted, a complete Human Health Risk Assessment (HHRA) examining all exposure pathways for pollutants of concern may be necessary to adequately characterize potential risks to human health. Where adverse health effects are predicted, any incidental effects such as effects on current use of lands and resources for traditional purposes will also be assessed. The proponent must provide a justification if it determines that an assessment of the potential for contamination of country foods is not required or if some contaminants are excluded from the assessment;
  • socio-economic conditions, including, but not limited to:
    • the use of navigable waters (including any water used for Indigenous transport)
    • forestry and logging operations
    • commercial fishing, hunting, trapping, and gathering activities
    • commercial outfitters
    • recreational use
    • food security
    • changes at the community level that affect socio-economic conditions for Indigenous peoples as result of increased population, economic activity, cost of living, among other factors
    • non commercial / trade economy
  • physical and cultural heritage, and structures, sites or things of historical, archaeological, paleontological or architectural significance to groups, including, but not limited to:
    • the loss or destruction of physical and cultural heritage
    • changes to access to physical and cultural heritage
    • changes to the cultural value or importance associated with physical and cultural heritage
    • changes to sacred, ceremonial or culturally important places, objects, or things
    • changes to visual aesthetics over the life of the Project
  • Other effects of changes to the environment on groups should be reflected as necessary.
6.3.5. Other valued components that may be affected as a result of a federal decision or due to effects on federal lands, another province or outside Canada.

If there is potential for the project to result in environmental changes on federal lands, lands in a province other than Manitoba, or outside of Canada as a result of the project, descriptions of effects will include, but are not limited to, a consideration of:

  • changes to ambient air quality on federal lands that may be affected by the project, including any changes in the concentration of the following contaminants, as relevant: total suspended particulates, fine particulates (PM2.5), particulate matters up to 10 micrometers in size (PM10), sulfur oxides (SOx), volatile organic compounds (VOCs), nitrogen oxides (NOx), and diesel particulates presented in concentration values comparable to guidelines (i.e. μg/m3);
  • changes to interprovincial wildlife, including any changes to the Manitoba North Range (MB9) boreal woodland caribou and the Beverly and Qamanirjuaq barren-ground caribou populations, habitat, movement or migratory corridors;
  • an estimate of the direct greenhouse gas emissions associated with all phases of the project in a regional, provincial, national and international context, as well as any mitigation measures proposed to minimize greenhouse gas emissions. This information is to be presented by individual pollutant and should also be summarized in CO2 equivalent per year.

If there is the potential for a change to the environment arising as a result of a federal decision(s), for example an authorization under section 35 of the Fisheries Act, the EIS should include a description of the specific project components for which a federal authorization/decision is required, and an assessment of any other valued components (not already covered in other subsections of these guidelines) that may be affected by the changes to the environment caused by these specific project components.

Such an assessment may include a consideration of the following:

  • changes to the use of waterways and water bodies;
  • effects to water quality, wetlands and aquatic invertebrate species at risk;
  • changes to recreational navigation;
  • effects to commercial trapping.

6.4. Mitigation measures

Every EA conducted under CEAA 2012 will consider measures that are technically and economically feasible and that would mitigate any significant adverse environmental effects of the project. Under CEAA 2012, mitigation measures includes measures to eliminate, reduce or control the adverse environmental effects of a designated project, as well as restitution for damage to the environment through replacement, restoration, compensation or other means. Measures will be specific, achievable, measurable and verifiable, and described in a manner that avoids ambiguity in intent or commitment, interpretation and implementation. Mitigation measures may be considered for inclusion as conditions in the EA decision statement and/or in other compliance and enforcement mechanisms provided by other authorities' permitting or licensing processes.

As a first step, the proponent is encouraged to use an approach based on the avoidance and reduction of the effects at the source. Such an approach may include the modification of the design of the project or relocation of project components.

The EIS will describe the standard mitigation practices, policies and commitments that constitute technically and economically feasible mitigation measures and that will be applied as part of standard practice regardless of location. The proponent will describe criteria used to estimate the technical and economic feasibility of potential mitigation measures and provide rational as to why certain mitigation measures were rejected. The EIS will then describe the project's environmental protection plan and its environmental management system, through which the proponent will deliver this plan. The plan will provide an overall perspective on how potentially adverse effects would be minimized and managed over time. The EIS will further discuss the mechanisms the proponent would use to require its contractors and sub-contractors to comply with these commitments and policies and with auditing and enforcement programs.

The EIS will then describe mitigation measures that are specific to each environmental effect identified. Mitigation measures will be written as specific commitments that clearly describe how the proponent intends to implement them and the environmental outcome the mitigation measure is designed to address.

The EIS will identify and describe mitigation measures to avoid, or lessen potential adverse effects on species and/or critical habitat listed under the Species at Risk Act. These measures will be consistent with any applicable recovery strategy and action plans. The EIS will also identify and describe mitigation measures to avoid or lessen adverse effects on listed COSEWIC species, and species harvested by Indigenous groups.

The EIS will specify the actions, works, minimal disturbance footprint techniques, best available technology, best management practices, corrective measures or additions planned during the project's various phases to eliminate or reduce the significance of adverse effects. The EIS will also present an assessment of the effectiveness of the proposed technically and economically feasible mitigation measures. The reasons for determining if the mitigation measure reduces the significance of an adverse effect will be made explicit. The proponent is also encouraged to identify mitigation measures for effects that are adverse although not significant.

The EIS will indicate what other technically and economically feasible mitigation measures were considered, and explain why they were rejected. Trade-offs between cost savings and effectiveness of the various forms of mitigation measures will be justified. The EIS will identify who is responsible for the implementation of these measures and the system of accountability.

Where mitigation measures are proposed to be implemented for which there is little experience or for which there is some question as to their effectiveness, the potential risks and effects to the environment should those measures not be effective will be clearly and concisely described. In addition, the EIS will identify the extent to which technological innovations will help mitigate environmental effects. Where possible, it will provide detailed information on the nature of these measures, their implementation, management and the requirements of the follow-up program.

Adaptive management is not considered as a mitigation measure, but if the follow-up program (refer to Section 8 below) indicates that corrective action is required, the proposed approach for managing the action (including resources) should be identified.

6.5. Significance of residual effects

After having established the technically and economically feasible mitigation measures, the EIS will present any residual environmental effects of the project on the VCs identified in Section 6.3 above. All residual effects, even if very small or deemed insignificant will be described.

The EIS will then provide a detailed analysis of the significance of the residual environmental effects that are considered adverse following the implementation of mitigation measures, using guidance described in Section 4 of the Agency's Operational Policy Statement, Determining Whether a Project is Likely to Cause Significant Adverse Environmental Effects under the Canadian Environmental Assessment Act, 2012 [16].

The EIS will identify the criteria used to assign significance ratings to any predicted adverse effects. It will contain clear and sufficient information to enable the Agency or review panel, technical and regulatory agencies, Indigenous groups, and the public to review the proponent's analysis of the significance of effects. The EIS will document the terms used to describe the level of significance.

The following criteria should be used in determining the significance of residual effects:

  • magnitude
  • geographic extent
  • timing
  • duration
  • frequency
  • reversibility
  • ecological and social context [17]
  • existence of environmental standards, guidelines or objectives for assessing the effect

In assessing significance against these criteria the proponent will, where possible, use relevant existing regulatory documents, environmental standards, guidelines, or objectives such as prescribed maximum levels of emissions or discharges of specific hazardous agents into the environment. The EIS will contain a section which explains the assumptions, definitions and limits to the criteria mentioned above in order to maintain consistency between the effects on each VC.

Where significant adverse effects are identified, the EIS will set out the probability (likelihood) that they will occur, and describe the degree of scientific uncertainty related to the data and methods used within the framework of this environmental analysis.

6.6. Other effects to consider

6.6.1. Effects of potential accidents or malfunctions

The failure of certain works caused by human error or exceptional natural events (e.g. flooding, earthquake, forest fire) could cause major effects. The proponent will therefore conduct an analysis of the risks of accidents and malfunctions across all phases of the Project, determine their effects, and present a preliminary emergency response measures and capacities.

Taking into account the lifespan of all different project components and temporal phases, the proponent will identify the probability of potential accidents and malfunctions related to the project, including an explanation of how those events were identified, potential consequences (including the environmental effects as defined in section 5 of CEAA 2012), the plausible worst case scenarios and the effects of these scenarios. Fate and behaviour modelling of potential spills of hydrocarbons, sodium cyanide, and ammonium nitrate to fish-bearing waterways may be considered across all seasons.

This assessment will include an identification of the magnitude of an accident and/or malfunction, including the quantity, mechanism, rate, form and characteristics of the contaminants and other materials likely to be released into the environment during the accident and malfunction events and would potentially result in an adverse environmental effect as defined in section 5 of CEAA 2012.

The EIS will describe the preventative measures and design safeguards that have been established to protect against such occurrences and the contingency and emergency response procedures that would be put in place if such events do occur. Environmental sensitivity mapping, including likely pathways, will identify areas sensitive to accident and malfunction scenarios that are located adjacent to project activities, such as streams and wetland areas frequented by fish and/or migratory birds.

6.6.2. Effects of the environment on the project

The EIS will take into account how local conditions and natural hazards, such as severe and/or extreme weather conditions and external events (e.g. flooding, drought, ice jams, landslides, avalanches, erosion, subsidence, fire, outflow conditions and seismic events), could adversely affect the project and how this in turn could result in effects to the environment (e.g. extreme environmental conditions that can contribute to and/or complicate malfunctions and accidental events). These events will be considered in different probability patterns (e.g. 5-year flood vs. 100-year flood).

The EIS will provide details of planning, design and construction strategies intended to minimize the potential environmental effects of the environment on the project.

6.6.3. Cumulative effects assessmen t

The proponent will identify and assess the project's cumulative effects using the approach described in the Agency's Operational Policy Statement entitled Addressing Cumulative Environmental Effects under the Canadian Environmental Assessment Act, 2012 and the guide entitled Technical Guidance for Assessing Cumulative Environmental Effects under the Canadian Environmental Assessment Act, 2012 [18].

Cumulative effects are defined as changes to the environment due to the project combined with the existence of other past, present and reasonably foreseeable physical activities. Cumulative effects may result if:

  • the implementation of the project may cause direct residual adverse effects on the VC, taking into account the application of technically and economically feasible mitigation measures; and,
  • the same VC may be affected by other past, present and future physical activities [19].

VCs that would not be affected by the project or would be affected positively by the project can, therefore, be omitted from the cumulative effects assessment. A cumulative effect on an environmental component may, however, be important even if the assessment of the project's effects on this component reveals that the effects of the project are minor.

In its EIS, the proponent will:

  • identify and provide a rationale for the VCs that will constitute the focus of the cumulative effects assessment, focussing the cumulative effects assessment on the VCs most likely to be affected by the project and other project and activities. To this end, the proponent must consider, without limiting itself thereto, the following components likely to be affected by the project:
    • fish and fish habitat, including salmon and other valued fish species;
    • species at risk;
    • migratory birds;
    • Indigenous peoples; and
    • any VCs associated with subsection 5(2) of CEAA 2012;
  • given the prior mining history at both sites, consider each VC not only in relation to current conditions, but conditions prior to historic mining, and identify changes/alterations in the interim, relevant to the consideration of cumulative effects;
  • identify and justify the spatial and temporal boundaries for the cumulative effect assessment for each VC selected. The boundaries for the cumulative effects assessments will generally be different for each VC considered. These cumulative effects boundaries will also generally be larger than the boundaries for the corresponding project effects;
  • identify the sources of potential cumulative effects. Specify other projects or activities that have been or that are likely to be carried out that could cause effects on each selected VC within the boundaries defined, and whose effects would act in combination with the residual effects of the project. This assessment may consider the results of any relevant study conducted by a committee established under section 73 or 74 of CEAA 2012;
  • assess the cumulative effects on each VC selected by comparing the future scenario with the project and without the project. Effects of past activities (activities that have been carried out) will be used to contextualize the current state of the VC. In assessing the cumulative effects on current use of lands and resources for traditional purposes, the assessment will focus on the cumulative effects on the relevant activity (e.g. hunting, fishing, trapping, plant harvesting) and also consider overall effects on Indigenous rights-based activities on their traditional lands and resources and health and socio-economic conditions. Cumulative effects must consider residual effects across multiple VCs;
  • describe the mitigation measures that are technically and economically feasible. The proponent shall assess the effectiveness of the measures applied to mitigate the cumulative effects. In cases where measures exist that are beyond the scope of the proponent's responsibility that could be effectively applied to mitigate these effects, the proponent will identify these effects and the parties that have the authority to act. In such cases, the EIS will summarize the discussions that took place with the other parties in order to implement the necessary measures over the long term;
  • determine the significance of the cumulative effects; and
  • develop a follow-up program to verify the accuracy of the assessment or to dispel the uncertainty concerning the effectiveness of mitigation measures for certain cumulative effects.

The proponent is required to engage with key stakeholders and Indigenous groups prior to finalizing the choice of VCs and the appropriate boundaries to assess cumulative effects.

7. Summary of Environmental Effects Assessment

The EIS will contain a table summarizing the following key information:

  • potential environmental effects on valued components;
  • proposed mitigation measures to address the effects identified above;
  • potential residual effects and the significance of the residual environmental effects

The summary table will be used in the EA Report prepared by the Agency or will be considered by the review panel. An example of a format for the key summary table is provided in Appendix 1 of this document.

In a second table, the EIS will summarize all key mitigation measures and commitments made by the proponent which will more specifically mitigate any significant adverse effects of the project on VCs (i.e. those measures that are essential to ensure that the project will not result in significant adverse environmental effects).

8. Follow-up and Monitoring Programs

A follow-up program is designed to verify the accuracy of the effects assessment and to determine the effectiveness of the measures implemented to mitigate the adverse effects of the project. Where there is uncertainty about effects outcomes, the proponent will show evidence of detailed follow-up and monitoring programs to identify change, and identify adaptive management measures that will be applied.

Considerations for developing a follow-up program include:

  • whether the project will impact the physical environment, environmentally sensitive areas/VCs, or protected areas or areas under consideration for protection;
  • the nature of Indigenous and public concerns raised about the project;
  • the accuracy of predictions;
  • whether there is a question about the effectiveness of mitigation measures or the proponent proposes to use new or unproven techniques and technology;
  • the nature of cumulative environmental effects;
  • the nature, scale and complexity of the program;
  • a description of proposed engagement with Indigenous groups in the planning and implementation of follow-up and monitoring; and
  • identify, with supporting rationale, how long post closure water will need to be managed and monitored; and
  • whether there was limited scientific knowledge about the effects in the EA.

The goal of a monitoring program is to ensure that proper measures and controls are in place in order to decrease the potential for environmental degradation during all phases of project development, and to provide clearly defined action plans and emergency response procedures to account for human and environmental health and safety.

8.1. Follow-up program

The duration of the follow-up program shall be as long as required to evaluate the effectiveness of the mitigation measures.

The EIS shall present a preliminary follow-up program and shall include:

  • objectives of the follow-up program and the VCs targeted by the program;
  • list of elements requiring follow-up;
  • number of follow-up studies planned as well as their main characteristics (list of the parameters to be measured, planned implementation timetable, etc.);
  • intervention mechanism used in the event that an unexpected deterioration of the environment is observed;
  • mechanism to disseminate follow-up results among the concerned populations;
  • accessibility and sharing of data for the general population;
  • opportunity for the proponent to include the participation of Indigenous groups and stakeholders on the affected territory and include Aboriginal traditional knowledge, during the development and implementation of the program;
  • involvement of local and regional organizations and Indigenous groups in the design, implementation and evaluation of the follow-up results as well as any updates, including a communication mechanism between these organizations and the proponent.

8.2. Monitoring

The proponent will prepare an environmental monitoring program for all phases of the project.

Specifically, the environmental impact statement shall present an outline of the preliminary environmental monitoring program, including the:

  • identification of the interventions that pose risks to one or more of the environmental and/or valued components and the measures and means planned to protect the environment;
  • identification of regulatory instruments that include a monitoring program requirement for the valued components;
  • description of the characteristics of the monitoring program where foreseeable (e.g., location of interventions, planned protocols, list of measured parameters, analytical methods employed, schedule, human and financial resources required);
  • description of the proponent's intervention mechanisms in the event of the observation of non-compliance with the legal and environmental requirements or with the obligations imposed on contractors by the environmental provisions of their contracts;
  • guidelines for preparing monitoring reports (number, content, frequency, format) that will be sent to the authorities and Indigenous groups concerned; and
  • plans to engage Indigenous groups in monitoring, where appropriate.

[5] Should an MMER Schedule 2 amendment be required for the project, the proponent is strongly encouraged to include MMER requirements for an assessment of alternatives for mine waste disposal in the EIS. The methodology recommended for the conduct of mine waste disposal alternatives is described in Environment and Climate Change Canada's Guidelines for the Assessment of Alternatives for Mine Waste Disposal (2011). A copy of this guide can be found on Environment and Climate Change Canada's website at www.ec.gc.ca. Proponent should also refer to Part 1, Section 4.1 of the present guidelines.
