Executive Summary Resource Proposed Action Alternative One Alternative Two are not anticipated to adversely affect aboveground historic properties within WFF. However, residential-scale turbines may have direct adverse effects on aboveground historic properties in WFF and indirect adverse effects on aboveground historic properties outside WFF. Transportation Temporary impacts on traffic flow would occur during construction activities. With implementation of mitigation and safety measures related to transportation and traffic closures due to oversize loads, no substantial impacts on transportation are anticipated. Aesthetics No adverse impacts on the public viewshed given the distance of the turbines from surrounding communities. Wind turbines would be white to blend in with sky. Potential adverse impacts on WFF employees and visitors within turbine shadow due to flickering effect of spinning blades on sunny days. anticipated to adversely affect aboveground historic properties within WFF.

Potential adverse impacts on WFF employees and visitors within turbine shadow due to flickering effect of spinning blades on sunny days. Implementation of solar panels would result in long-term changes to the viewshed at the Main Base. Because WFF is a highly properties within WFF. However, residential-scale turbines may have direct adverse effects on aboveground historic properties in WFF and indirect adverse effects on aboveground historic properties outside WFF. Temporary impacts on traffic flow would occur during construction activities. With implementation of mitigation and safety measures related to transportation, no substantial impacts on transportation are anticipated. Implementation of solar panels would result in longterm changes to the viewshed at the Main Base. Because WFF is a highly industrialized setting with numerous antenna arrays and other infrastructure, solar panels should not present a negative impact on the viewshed. viii
Executive Summary Resource Proposed Action Alternative One Alternative Two industrialized setting with numerous antenna arrays and other infrastructure, solar panels should not present a negative impact on the viewshed. Cumulative Effects There would be adverse cumulative impacts on avifauna from construction and operation of the wind turbines. Cumulative impacts on wetlands would be mitigated. There would be beneficial impacts on air quality due to reduced GHG emissions and lowered use of fossil fuels during the production of electricity. There would be adverse cumulative impacts on avifauna from construction and operation of the wind turbines. Cumulative impacts on wetlands would be mitigated. There would be beneficial impacts on air quality from the use of wind turbines and solar panels due to reduced GHG emissions and lowered use of fossil fuels during the production of electricity. Beneficial impacts on regional air quality would result from the operation of the solar panels, which are a fossil fuel-free power source. No other cumulative impacts from installation of solar panels are anticipated. ix
