WASHINGTON (Reuters) - The U.S. Environmental Protection Agency has finalized rules to curb pollution from industrial boilers and large incinerators, revising earlier versions to target only the largest polluters and give them more time to comply.
The agency on Friday formalized standards it initially released in March 2011 for reducing toxic air pollution, including mercury and particle pollution, known as soot, from boilers and solid waste incinerators.
Boilers, which are typically fired by coal, oil, natural gas and biomass, are used to power heavy machinery and provide heat for industrial processes.
