•Banning most dangerous types of poles
•technical standards for bird safety for new and retrofitted facilities
Collision
Birds and Power Lines
Collision
• underground location of cables where possible
• Line routing planning not in areas with high bird importance
• single-level arrangement of conductor cables with no neutral cable above or clearly visible markers attached to high-risk cables
