Avian-safe. A power-pole configuration designed to minimize avian electrocution risk by providing sufficient separation between phases and between phases and grounds to accommodate the wrist-to-wrist or head-to-foot distance of the bird. For eagles, this is 150 centimeters of horizontal separation and 100 centimeters of vertical separation. If sufficient separation cannot be provided, exposed parts that conduct electricity must be covered to reduce electrocution risk. If covers are used, they must be maintained in good condition. For conversions from an above-ground line to a buried line, the buried portion is considered "avian-safe." For purposes of the regulations in this section, "avian-safe" means safe for eagles.
Collision response strategy. A plan that describes the process the permittee will follow to identify whether a collision-caused injury or mortality has occurred, to evaluate factors that contributed to the collision, and to implement risk-reduction measures commensurate with the collision risk.
Proactive retrofit strategy. A plan to convert existing infrastructure to avian-safe infrastructure within a set timeline. The strategy must identify a baseline of poles to be proactively retrofit. The existing-infrastructure baseline must include all poles that are not avian-safe for eagles located in areas identified as high risk to eagles and may also include other poles in the service area.
Reactive retrofit strategy. A plan to respond to incidents where eagles are electrocuted or killed. The reactive retrofit strategy must include information on how eagle electrocutions are detected and identified. Determining which poles to retrofit must be based on the risk to eagles and not on other factors (e.g., convenience or cost). The pole that caused the electrocution must be retrofitted unless the pole is already avian-safe. A total of 13 poles or a half-mile segment must be retrofitted, whichever is less, prioritizing the highest risk poles closest to the electrocution event.
Shooting response strategy. A plan that describes the process the permittee will follow when eagles are found killed or injured near power-line infrastructure to identify if shooting is suspected, to communicate with law enforcement, and to identify and implement appropriate shooting reduction measures.
