Summary of Mitigation and Enhancement Measures
• Limit vegetation clearing and revegetate, demarcate work areas,
establish habitat corridors;
• Driver (and general staff) training on ecological sensitivities and
enforce 25 km/h speed limit on site;
• Effective site drainage, and sediment/silt trapping mechanism,
cut-off drains, oil/water separators and silt traps and drainage
installations for heavy rainfall events;
• Development of a BMP enlisting the services of an entomologist
and botanist. This will include demarcation of floral and faunal
species to avoid accidental damage during construction, and the
retention or relocation of Threatened species creating suitable
habitats;
• Train all staff on ecological sensitivities to ensure that they are
aware of any specific migratory routes for faunal species, are
able to identify species of a Threatened status and enforce an
anti-poaching policy;
• Spray surfaces prior to excavation and clearing, apply liquid
asphalt and use binder materials for exposed surfaces and fit
dust suppression/ extraction to equipment; and
• Shielded and downward-directed security and work lighting
and avoid tall mast lights, if possible.

• Driver (and general staff) training on ecological sensitivities and

• Effective site drainage, and sediment/silt trapping mechanism,
cut-off drains, oil/water separators and silt traps and
permanent drainage installations for heavy rainfall events.
• Demarcate work and demolition areas;
• Spray surfaces prior to excavation and clearing, apply liquid
asphalt and use binder materials for exposed surfaces and fit
dust suppression/ extraction to equipment; and
• Rehabilitation and revegetation of the site using native floral
species, where appropriate and before the wet season.
