The EPA is approving Arizona's plan to reduce sulfur dioxide pollution in the Hayden area to meet federal air quality standards that have been in place since 1971 and updated in 2010. This plan affects people living and working in the Hayden area, as well as industrial facilities like smelters that release this pollutant, and it matters because sulfur dioxide can cause serious respiratory problems and other health issues, especially for children and people with asthma. Arizona's plan sets specific pollution reduction targets and timelines to bring the air quality up to levels the federal government considers safe for public health.
