The Clean Air Act makes the Environmental Protection Agency (EPA) responsible for setting air quality standards regarding “criteria pollutants.” Among these pollutants is sulfur dioxide (SO2), a highly reactive gas that affects air quality and has the potential to cause respiratory illnesses in those exposed to it. Power plants that process fossil fuels are a primary source of SO2 emissions and other pollutants. To maintain compliance with the EPA’s SO2 designations, power plants look to temporary climate solutions and protective surface coatings to improve emission controls and prolong the life of the equipment used.
