IRMA Standard for Responsible Mining (Draft 2.0)
Chapter 4.1 Environmental and Social Impact Assessment
In almost all jurisdictions, mining companies are required to conduct environmental impact assessments (EIA) or environmental and social impact assessments (ESIA) prior to mine development, and some also require them prior to exploration. ESIA enable regulators and other stakeholders to review predicted impacts and mitigation measures for a mining proposal before it is finalized or approved.
The importance of stakeholder involvement in ESIA is increasingly recognized, improving the quality of the assessments and helping to build community support for a project by involving local stakeholders in the process and associated decision-making.
Objectives/Intent of this Chapter
To proactively anticipate, avoid, and when that is not possible, minimize and compensate for impacts on affected communities, workers and the environment through the assessment, management and monitoring of environmental and social impacts.
Scope of Application
New versus Existing Mines: ESIAs are typically undertaken to predict potential impacts from a proposed mining project, and often are mandated by host country regulatory agencies. For IRMA’s purposes, mines that did not carry out an ESIA prior to the mine development will not be expected to subsequently carry out such an assessment. But they will be expected to demonstrate that an environmental and social management plan (or its equivalent) and monitoring programs are in place to detect impacts. Additionally, criterion 4.1.5 requires the collection of baseline data. For projects where baseline data was not collected at the appropriate time, the applicant shall collate and present data to provide the best possible picture of baseline conditions.
NOTES TO READERS ON MAJOR CHANGES TO THIS CHAPTER
- This was previously Chapter 5.1.
- Revised previous 5.1.2 Scoping (now 4.1.2) to include some of the requirements previously in 5.1.3 Provision of Preliminary Information; revised previous 5.1.6 Impact Analysis (now 4.1.6), to provide more clarity on expectations for this step; and revised Stakeholder Participation and Disclosure criteria to remove duplication with Chapter 2.8 (we reference relevant sections of the IRMA Standard in footnotes and the table of Cross References to Other Chapters below).
- Added a new section 4.1.7. ESIA Report.
- Deleted Chapter 5.2—Environmental and Social Impact Monitoring. This was done because many chapters specifically address monitoring, and so it created overlap/duplication within the Standard. We created a specific monitoring criterion (4.1.8) in this chapter; and integrated monitoring-related issues directly into some other criteria (e.g., 4.1.4 on stakeholder participation, and 4.1.9 on disclosure).
- Removed the requirement for a permanent monitoring advisory group, as the role of this group overlapped with the independent experts in 22.214.171.124. Instead, added a permanent “stakeholder advisory group” into Chapter 2.8—Community and Stakeholder Engagement, which could play such a monitoring oversight role.
The means of verification (MOV) have been removed from this version of the draft IRMA Standard. If you would prefer to review and comment on a version of the draft Standard that has the means of verification, you can download a pdf version of the Standard with MOV.

220.127.116.11. The existence of publicly available information, and the means of accessing it, shall be publicized by appropriate means.
In many jurisdictions there are legal requirements for undertaking ESIA. Similarly, ESIA are often mandated by organizations that provide funding for projects (e.g., International Finance Corporation (IFC)/World Bank). The requirements of Chapter 4.1 align with the good practice requirements described by IFC Performance Standard 1: Assessment and Management of Environmental and Social Risks and Impacts.
Where documents and records produced in satisfaction of legal or other organization’s requirements also meet the requirements of the IRMA standard the operating company is not required to duplicate these. A company may choose to develop summaries and explanations of such documents and records in order to facilitate the IRMA audit process and thereby reduce its cost.
The standard does not list the issues and impacts that are likely to be significant, as these will vary greatly depending on the scale, nature, duration and location of the particular project. It is the responsibility of the operating company, in consultation with interested and affected stakeholders, to ensure that all the relevant issues and impacts are identified and considered. Issues/ impacts to be considered may include (but are not limited to) the following:
Environmental impacts (e.g. surface disturbance, waste generation, air quality, biodiversity, species at risk, noise, water use and quality, spills);
Social impacts (e.g. housing, infrastructure, social services, poverty, community physical and mental health and safety, local economies, resettlement, ecosystem services, employment, population movements, differential and/or specific impacts on women);
Labor and working conditions;
Trans-boundary effects (e.g. air pollution, use of international waterways);
Greenhouse gas emissions;
Potential impacts on World Heritage Sites;
Potential impacts on Indigenous peoples and/or other vulnerable individuals or groups (e.g., women, ethnic minorities, youth and elderly, etc.), including impacts on culture and cultural heritage;
- Socio-political risks, including e potential infringement of human rights, conflict and political instability.
An ESIA that meets the requirements of this chapter is a critical step in informing interested and affected stakeholders and rights holders including, where applicable, indigenous peoples about a proposed project and its potential impacts, prior to decision-making. The fact that an effective ESIA has been designed and implemented does not imply that a project should necessarily proceed. With effective engagement of stakeholders, however, it should provide a sound basis for consideration as to whether a project should or should not proceed.
Cross Reference to Other Chapters
|1.1—Legal Compliance||As mentioned in Chapter 1.1, companies are required to abide by host country law. Consequently, if there is an ESIA process mandated by a regulatory agency within the host country, the company will be required to participate in that process. However, if that process does not include some of the elements of the IRMA ESIA chapter, the operating company will be expected to demonstrate that measures were taken to meet the IRMA requirements, as well.|
|2.4—Human Rights Compliance and Due Diligence||If the infringement of human rights is predicted during cultural heritage assessment, or if human rights related to cultural heritage have been infringed upon at a new or existing mines, a company will be expected to prevent, mitigate and remediate the impacts as per Chapter 2.4. This includes the mitigation or remediation of human-rights-related impacts from past cultural heritage management activities at existing mines.|
|2.3—Emergency Preparedness and Response||Potential impacts related to community safety, and mitigation strategies identified in the ESIA should feed into the Emergency Response Plan and planning processes described in Chapter 2.3.|
|2.8—Community and Stakeholder Engagement||
Capacity building or training may be needed to ensure effective, effective participation by stakeholders in the ESIA process (see 4.1.4). The primary reference for that requirement is 2.8.3 Strengthening Capacity, in Chapter 2.8.
Disclosure of information shall meet the requirements of Chapter 2.8. In particular, information mentioned in 18.104.22.168 to 22.214.171.124 shall be in formats and languages that are culturally appropriate, accessible and understandable to affected stakeholders. See criterion 2.8.4 for more details.
|2.10—Free, Prior and Informed Consent||Implementation of ESIA requirements can be integrated with the free, prior and informed consent process described in Chapter 2.10. However, it should be emphasized that indigenous peoples’ participation in the ESIA process, including in the consideration of proposals to mitigate expected impacts does not, of itself, imply consent, even if the recommended actions to minimize impacts are fully implemented.|
|3.2—Water Quantity||Section 126.96.36.199 requires that a Conceptual Flow Model (CFM), or its functional equivalent, be utilized as part of the groundwater analysis in an Environmental and Social Impact Assessment, and provides details on how the CFM is to be utilized in this analysis.|
|Multiple chapters that require risk or impact assessment||
There are numerous chapters in the IRMA Standard that require risk or impact assessments. These assessments may be integrated into the ESIA, if the timing works, and the relevant information and analyses are included in the ESIA.
Information produced for other assessments may also feed into the ESIA process (i.e., collection of some data may have already occurred, as well as an analysis of potential significance of some issues). Conversely, if other assessments occur later than the ESIA, the data and analysis carried out for the ESIA may feed into those assessments.
The following chapters include reference to risk or impact assessment: 2.4—Human rights Due Diligence; 2.5—Mining and Conflict Affected Areas; 2.6—Security Arrangements; 2.7—Community Health and Safety; 2.9—Obtaining Community Support and Delivering Benefits; 2.11—Cultural Heritage; 2.12—Resettlement; 3.1—Water Quality; Chapter 3.7—Protected Areas; Chapter 3.8—Biodiversity Outside of Protected Areas; and Chapter 4.2—Reclamation and Closure.
|Multiple chapters that require monitoring||
Several IRMA chapters have their own monitoring specifications, some of which may not entirely align with all of the ESIA monitoring requirements in Chapter 4.1. Where they differ, the chapter requirements take precedence. If there are no particular requirements, then the expectation is that any significant impacts related to those chapters will be captured in the ESIA monitoring program.
The following chapters include references to monitoring: 2.1—Fair Labor and Terms of Work; 2.2—Occupational Health and Safety; 2.4—Human rights Due Diligence; 2.5—Mining and Conflict Affected Areas; 2.6—Security Arrangements; 2.7—Community Health and Safety; 2.9—Obtaining Community Support and Delivering Benefits; 2.12—Resettlement; 3.1—Water Quality; 3.2—Water Quantity; 3.4—Air Quality; 3.5—Noise; 3.7—Protected Areas; Chapter 3.8—Biodiversity Outside of Protected Areas; 3.9—Cyanide; 3.10—Mercury; and Chapter 4.2—Reclamation and Closure.
1. Scoping refers to the early, open and interactive process of determining the major issues and impacts that will be important in decision-making on the proposal, and need to be addressed in an ESIA. IRMA Guidance will provide more information on ESIA scoping.
2. Facilitation may include the provision of information and explanations in local languages, using materials and approaches designed to be accessible to local communities, and providing capacity building or training on methods. See also Chapter 2.8, Criteria 2.8.3.
3. Characteristics of impacts will vary, but may include: nature (positive, negative, direct, indirect, cumulative); magnitude (sever, moderate, low); extent/location (area/volume covered, distribution); timing (during construction, operation, closure and reclamation; immediate, delayed, rate of change); duration (short or long term; intermittent or continuous); reversibility/irreversibility; likelihood (probability, uncertainty or confidence in the prediction); and significance (local, regional, global).
4. The UN University has developed guidance on international theory and practice of environmental (and social) impact assessment and has outlined other elements typically contained in an ESIA report.:
5. E.g., if monitoring indicates that effects are greater than predicted; or if there is a change in mining activities that warrants an update.
6. For example by allowing independent experts to have access to sites for monitoring social or environmental indicators, and by allowing access to relevant company records, reports or documentation.
7. See Chapter 2.8 for requirements related to Communications and Access to Information (2.8.4).
8. E.g., local radio, leaflets, local meetings.
