The Environmental Protection Agency has updated the rules that govern emissions allowed by new power plants. Following the public comment period, these pollution limits will restrict the amount of mercury, hydrogen chloride, sulfur dioxide, and lead.
The new standards apply only to new coal and oil-fired power plans that will be built in the future, and does not change the emission limits for existing power plants.
Supporters say the rules are need to create cleaner air and reduce health-related impacts caused by pollution like heart attacks, premature deaths, childhood asthma symptoms and bronchitis. But it's a small step compared to ramping up investment in clean, renewable power. While new power plans may be regulated slightly differently they will still contribute to pollution and carbon emissions.
