(CN) – The EPA plans to remove 13,000 tons per year of hazardous air pollutants by regulating emissions from 1 million reciprocating internal combustion engines used by hospitals and power companies. The agency predicts owners will spend $528 million to retrofit existing units but also expects benefits worth up to $2 billion from reduced health care costs and fewer cancer deaths.
In addition to removing the most directly toxic pollutants from the air, the operating changes required by the proposed rule are expected to substantially reduce emissions of green house gases such as carbon monoxide, nitrous oxide, sulfur dioxide, and mono-nitrogen oxides. In the case of carbon monoxide, the reduction is estimated to be more than 510,000 tons per year in 2013.
