Use of refined coal at power plants has been incentivized in tax law due to perceived benefits in control of criteria air pollutants. Refined coal use at power plants increased by 20% from 99 million metric tons in 2016 to 119 million metric tons in 2020. Additives in the refining process (, halogens) can be present in power plant wastewater, especially where wet flue gas desulfurization ...
