Gatineau – April 22, 2025 – Global Affairs Canada have determined that the project Multi Country Humanitarian Response Canada Lutheran World Relief in Somalia is not likely to cause significant adverse environmental effects.

This determination was based on a consideration of the following factors:

• technically and economically feasible mitigation measures.

Mitigation measures considered for this determination are:

Vegetation and Site Management

• Limit vegetation clearing to the necessary work area.
• Restore construction sites to their natural state after work is completed.
• Use excavated materials for backfilling trenches around pipes.

Waste Management

• Prohibit waste burning on site.
• Prevent soil erosion at community water sources.
• Train workers on proper waste separation and disposal.
• Design landfill sites with traps for leachate accumulation and treatment.
• Line leachate ponds with impermeable membranes.
• Locate landfill sites at least 1 km away from water sources.

Sanitation and Wastewater Management

• Direct drainage water to septic tanks or protected ponds for treatment.
• Seal fecal matter containment facilities to prevent water contamination.
• Conduct soil permeability tests to determine safe distances between containment facilities and water sources.
• Make containment infrastructure watertight if the water table is high or in case of flooding.
• Build elevated toilets or septic tanks to prevent environmental contamination.
• Avoid drainage or overflow from septic tanks that could contaminate surface or groundwater.

Dam Design and Maintenance

• Identify permeable layers during excavation and seal them if present.
• Compact dam foundations and walls to 95% of optimal AASHTO 99 compaction or applicable standards.
• Line the dam foundation with an impermeable membrane to prevent leaks and washout of unconsolidated soils.
• Use depressions as natural spillways if the bottom level is roughly at the required storage level.
• Design spillways to accommodate maximum flood levels from the dam's catchment area.
• Protect the base and sides of spillways from erosion by high-speed water.
• Incorporate adequate energy dissipators at spillway outlets.
• Initiate preventive maintenance to monitor reservoir volumes, dam integrity, spillway characteristics, and sediment load, especially during the dry season.

Electronic Waste Management

• Implement a waste management plan and establish mechanisms to manage electronic waste from solar energy and other electronic devices (computers, printers, servers, cables, etc.).

Global Affairs Canada is satisfied that that the carrying out of the project is not likely to cause significant adverse environmental effects.

Therefore, Global Affairs Canada may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
