The US Environmental Protection Agency (EPA) has finalised Steam Electric Effluent Limitation Guidelines, which are expected to reduce toxic pollutant discharge in the country’s waterways from steam-based power plants. In addition to lowering the annual pollutant discharges by 1 billion kg, the new regulation will also cut water withdrawal by 57 billion gallons a year. Reductions are expected to save $463 million a year.

Gina NcCarthy, Administrator with the EPA, said: “EPA is setting the first national limits to protect public health and reduce toxic pollutants, including mercury, arsenic, lead, and selenium released into America’s waterways by steam electric power plants. These cost-effective, achievable limits will provide significant protections for our children and communities across the country, including minority and low-income communities, from exposure to pollutants that can cause neurological damage in children, cancer, and other serious health problems.”

The new regulations have been based on readily available technologies that are widely used across the power sector, and are in line with industry initiatives for generating clean energy.

According to the EPA, the USA has around 1080 steam-driven power generation facilities that are responsible for about 30 per cent of the toxic pollutants discharged into streams, rivers, and lakes. About 134 of the plants will be prompted to investment in meeting these new standards. However, the regulations do not apply to oil-fired facilities or those generating less than 50 MW.
