Quick Answer
Conduct an environmental review for wind sites by assessing potential impacts on wildlife, noise pollution, and visual resources. This involves evaluating factors like bird migration patterns, noise levels, and turbine placement. Local regulations and expert consultations are also crucial.
Assessing Wildlife Impacts
When evaluating wildlife impacts, consider the species and their habitats. For example, eagles and hawks are sensitive to wind turbine noise, so turbines should be placed at least 1.5 kilometers away from raptor habitats. Assessing bird migration patterns can be done by consulting with bird experts or using tools like the National Renewable Energy Laboratory’s (NREL) Wind Turbine Collision Risk Model. This model estimates the number of bird fatalities at a wind farm based on factors like turbine size, location, and bird migration patterns.
Evaluating Noise Pollution
Evaluate noise pollution by measuring noise levels in the surrounding area and assessing the impact on local residents. In the United States, the Federal Aviation Administration (FAA) requires wind turbines to be at least 7 kilometers away from residential areas. Noise levels can be reduced by using sound-reducing technologies like acoustic barriers or by placing turbines farther apart.
Considering Visual Resources
Evaluate the visual impact of wind turbines on the surrounding landscape. Consider factors like turbine size, placement, and visibility from nearby roads or trails. The American Wind Wildlife Institute recommends placing turbines in areas with low visibility, such as near roads or in areas with existing infrastructure.
