Uzbekistan - Talimarjan Transmission Project : safeguards diagnostic review : Avian risk assessment (Inglês)

The objective of the Talimarjan Transmission Project is to address the potential effects of the Talimarjan Overhead Transmission Line (TOTL) project on resident and migratory birds, the World Bank has requested that an Avian Risk Assessment (ARA) be prepared. This ARA will characterize the likelihood or potential risks to birds from collisions and/or electrocutions associated with the TOTL project and determine whether these risks will cause biologically significant adverse effects to resident and migrating birds found in the vicinity of the TOTL route. Strategies for addressing collisions should ensure that the transmission lines are sufficiently visible to birds in flight. Mitigation measures to address risk of collision are warranted and should be identified during final rights-of-ways (ROW) selection and design at the conclusion of preconstruction surveys that will identify high use areas where collisions may occur. Mitigation measures may include rerouting certain segments to avoid high use bird areas and/or the use of markers and flight diverters to make the lines more visible. These decisions should be done in consultation with the World Bank, Uzbekenergo, and other non-government organizations (NGOs) such as UIZ. Strategies for addressing electrocution should ensure distances between energized components or between energized and grounded components are sufficient to avoid electrocution of birds and should include the use of perch guards to reduce the likelihood of perching, roosting, and nesting, which in some circumstances leads to ?streamers. These collision and electrocution mitigation strategies should be site specific, where warranted, and tailored to the relative risks in each geographic location along the TOTL route.
