5. Environmental Attributes - Low Air Emissions GHG – Less that 0.4 tonnes/MWh (less than half of the emissions from Coal) SOx – Virtually none NOx – Shepard will only emit between 3 ppm and 6 ppm PM – virtually none Mercury – No mercury emissions We did extensive air dispersion modeling and Shepard has minimal impact on air quality in the region.
