3. Overview
Context
3.1 Environmental emergency preparedness and response (EEPR) in the DND and the CAF is:
- identified as a key process in the environmental management system; and
- overarching and aimed at ensuring the ability to minimize the impact of environmental emergencies that can occur from the release of regulated substances.
3.2 Substances identified by the Government of Canada under the Environmental Emergencies Regulations, 2019 pose an increased risk of causing environmental emergencies when stored in sufficient quantities. Likewise, other substances and circumstances may also cause environmental emergencies as identified by an environmental risk assessment (ERA) or legislation.
3.3 For EEPR, risk assessments focus on the potential environmental risks and must be referred to as ERA.
3.4 A robust EEPR process is a key component of environmental management system controls that supports prevention and mitigation of environmental emergencies, while:
- improving engagement with the local community; and
- reducing impacts to human health, property, environment and business continuity.
3.5 EEPR is one of many facets of site or system emergency response plans (ERPs), alongside other functional areas such as fire safety, nuclear safety and health and safety. Preparedness and response include planning, testing, responding, notifying, reporting, oversight and training.
Note – In this DAOD, ERPs are understood to be location-specific, based on the risk assessments and procedures for dealing with emergency situations.
3.6 Provincial, territorial, and municipal legislation such as laws, guidelines, and by-laws along with international and host-nation legislation for activities outside Canada define requirements for EEPR unless they are contrary to federal laws or regulations on the same subject or impair the fulfilment of the federal legislation and mandate.
3.7 The DND and the CAF must comply with the local laws that are considered more stringent than federal laws.
Purpose
3.8 The purpose of this DAOD is to provide direction on the obligation to prevent, prepare for, respond to and recover from environmental emergencies with the goal of reducing risk to the environment.
Application
3.9 EEPR is required for substances identified as having an increased potential to cause environmental emergencies including:
- Environmental Emergencies Regulations, 2019 Schedule 1 list of substances;

4. Operating Principles
4.1 The DND and the CAF are committed to preparing for, and responding to, environmental emergencies by adhering to legislative requirements as well as best management practices. Integrating EEPR across existing emergency response planning prevents and mitigates the impacts of environmental emergencies while maintaining operational readiness. Resources applied to planning, implementation, monitoring and reporting must be proportional to the level of risk of actual or potential environmental emergencies.
4.2 If environmental emergencies may impact Indigenous peoples, DND and the CAF are committed to undertaking engagement and consultation to fulfil applicable obligations, including legal and policy obligations such as Aboriginal and treaty rights and those under the United Nations Declaration on the Rights of Indigenous Peoples, Articles 29 and 30.
4.3 Among other key outcomes, integrated management helps provide for the:
- mechanisms for minimizing risk, loss and damage by considering risks to the environment and human health;
- protection of assets, resources and services;
- preservation of water, soil, and air quality;
- identification of potential hazards;
- establishing of systems for preventing releases; and
- guidance for a timely and effective response to owners, operators and emergency response personnel, in the event of releases.
5. Planning
5.1 The planning of EEPR management must adhere to applicable ADM(IE) policies.
5.2 Effective planning:
- demonstrates due diligence and reduces potential impacts on the environment;
- involves maintaining inventories along with quantities of substances and hazardous waste, accessible to relevant stakeholders, as part of determining applicable requirements, ensuring safe handling, storage, transport and managing risk;
- defines preparedness and response measures, including training, simulation exercises, public notification and Indigenous engagement and consultation to be implemented in line with an ERA; and
- integrates environmental considerations into emergency response planning.
Environmental Risk Assessment
5.3 An ERA is part of the planning process to determine where environmental emergencies might take place. A new or existing and up-to-date ERA:
- defines substances, their use, and related risks;
- identifies the nature and sensitivity of the receiving environment and considers the impacts to specific receiving environments;
- assesses resources available during a response;
- provides a quantified risk level based on established criteria; and
- results in identifying where measures are needed in an ERP to protect the environment and human health.
Emergency Response Plan
5.4 An ERP provides personnel with the operational guideline to follow in the event of emergencies that includes:
- identifying local Indigenous peoples and communities that must be engaged or consulted in the event of an environmental emergency that may impact them; and
- environmental considerations implemented into the ERP to reduce the impacts, losses and damages caused by environmental emergencies, while also meeting legislative requirements.
6. Implementation
6.1 Simulation exercises are a pivotal component of ensuring environmental emergencies can be effectively managed. Results are then used to update and track improvements to ERPs.
6.2 Individuals are required to have the necessary training, resources and equipment to carry out their tasks as described in the ERP. The DND and the CAF must ensure validity of related training and qualifications.
6.3 Proactive disclosure to the public of potential risks from environmental emergencies must adhere to DAOD 2008-0, Public Affairs Policy and meet legislative requirements.
7. Monitoring and Reporting
Monitoring
7.1 Monitoring the integration and implementation of the EEPR process is essential to ensure compliance with legislative requirements and ongoing performance for environmental protection.
7.2 Monitoring for EEPR includes, at a minimum:
- ensuring compliance with legislative and policy requirements, as well as ongoing performance for environmental protection;
- reviewing all EEPR policy and procedures for ongoing validity; and
- auditing of policy-driven activities and reporting trends as compared against key performance indicators (KPI).
Reporting
7.3 The DND and the CAF are responsible for internal and external reporting on various aspects of EEPR that include, release reporting and the registration of prescribed facilities. Reporting on Indigenous engagement and consultation is completed by using the Indigenous Initiatives Tracker.
8. Release
Criteria
8.1 Determination that an environmental emergency has occurred includes assessing whether the release meets certain criteria. Criteria vary based on the substance released and its quantity, concentration, location and statutes. In case it is unclear whether a release constitutes an environmental emergency, reporting should proceed.
Prevention
8.2 Environmental emergencies due to releases must be prevented through:
- diligent implementation of the technical planning, designing, operation and maintenance, including standard operating procedures; and
- eliminating or mitigating, if possible, risk sources identified through ERAs by swapping substances for less harmful alternatives, amending procedures or implementing other controls.
Environmental Emergency
8.3 If there is an imminent or potential danger to the public because of an environmental emergency, and following such an event:
- public notification measures must be undertaken in accordance with DAOD 2008-0; and
- care must be taken in the awareness and engagement with Indigenous communities that could be adversely impacted by environmental emergencies.
9. Record Keeping
9.1 Record keeping:
- is an important element of demonstrating compliance to environmental enforcement officers;
- allows for analysis of data to determine trends, identify challenges, and define improvements;
- aligns with the DND and CAF Data Management Strategy whereby data is managed as a shared asset; and
- allows data to be leveraged in all aspects of DND and CAF programs by:
- enhancing capabilities and decision-making; and
- providing an information advantage during military operation.
9.2 At minimum, the following types of records regarding EEPR must be maintained and accessible as per the DND Data Management Strategy:
- ERAs;
- ERPs and procedures;
- simulation exercise records and evaluation;
- training records that demonstrate users are appropriately instructed/qualified for the implementation of EEPR; and
- notification and reporting records (e.g., notices to local community and environmental regulator, and reportable environmental emergencies).
10. Oversight
10.1 Effective oversight must:
- promptly identify non-compliance with environmental requirements;
- ensure appropriate corrective steps are recommended; and
- ensure mitigative measures to prevent similar occurrences are implemented.
10.2 At minimum, oversight must include:
- assessing compliance with environmental requirements and related KPIs;
- reviewing ERPs and related ERAs and testing records and, where appropriate, defining and implementing needed improvements to correct and prevent issues; and
- providing risk-based status reporting for senior management.
