MOXIE FREEDOM POTENTIAL ENVIRONMENTAL IMPACTS AND MITIGATION
All impacts to neighbors and the environment are intended to be minimized to the greatest extent practical. Both noise and visual impacts to residents of Salem Township will be minimized by location away from populated areas, facility design standards, and set-back distances from the facility property line. With this location, building enclosures, and other noise-dampering measures, sound levels at the nearest residences to the plant's property line will not be increased noticeably from existing levels.
In addition, the presence of a modern, low-emission power plant will help shift the source of power away from older plants with greater air emissions. By using only natural gas for fuel and the Best Available Control Technology (BACT) for air emissions control, the Moxie Freedom Generation Plant will produce nitrogen oxide and carbon monoxide emissions that are about 80 percent less than a comparable new coal plant, carbon dioxide emissions that are about 45 percent less than a comparable coal plant, and sulfur dioxide and particulate emissions that are more than 99 percent less than a comparable coal plant. In total, Moxie Freedom will meet or beat all Pennsylvania and national air compliance and health-based standards. This shift away from inefficient dirty power is both a local benefit and a regional benefit in terms of air quality.
Importantly, Moxie Freedom intends to use a cooling system that does not depend on drawing large amounts of water from the Susquehanna River or groundwater resources. In fact, no river water will be used at all for cooling purposes. Instead, the project will use air-cooled condensers. These devices function much like a car radiator where cooling is done by fans moving air over finned tubes. Use of air-cooled condensers eliminates any river impacts, including potential impacts to species of special concern. It also eliminates any potential for vapor plumes that can be visible under certain atmospheric conditions. Fan noise will be minimized using special blade design and low output motors.
