Mitigation Hierarchy and Environmental Management Plan

An Environmental Management Plan (EMP) converts assessment findings into assigned actions, performance criteria, monitoring, records and corrective responses.

## 1. Apply the mitigation hierarchy 1. Avoid: change the site, layout, timing or process to prevent the impact. 2. Minimize: reduce the magnitude, duration or likelihood of unavoidable impacts. 3. Restore: rehabilitate disturbed areas and affected resources. 4. Offset: consider only for eligible residual impacts after the preceding steps and under applicable policy.

## 2. Examples by project type | Project | Example management measures | |—|—| | Industrial facility | Enclose material transfer, maintain air-pollution controls, segregate drains, provide secondary containment and manage hazardous waste | | Wastewater plant | Control odour at source, maintain standby equipment, prevent untreated bypasses, manage sludge safely and monitor final effluent | | Drinking-water project | Protect source areas, manage treatment chemicals, control residuals, maintain disinfection barriers and manage pipeline reinstatement |

## 3. EMP implementation matrix | Impact / risk | Action | Performance indicator | Monitoring / frequency | Responsible role | Record / corrective action | |—|—|—|—|—|—| | Example: dust | Apply dust suppression | Visible dust / measured indicator | Defined by risk and permit | Site environmental lead | Inspection log and escalation |

## 4. Make actions auditable Each action needs a responsible role, implementation timing, measurable indicator, acceptance criterion, monitoring method, reporting route and escalation trigger. Align commitments with permits, design specifications and contractor requirements.

## 5. Emergency preparedness Include credible spill, fire, equipment failure, power loss, extreme weather and accidental release scenarios. Define notification, containment, response equipment, training, drills and post-incident review.

## 6. Adaptive management Use monitoring results and complaints to review whether controls are effective. Record non-conformities, root causes, corrective actions, owners, deadlines and closure evidence.
