Study blames local sources for haze in southern Appalachians

In this mention

A 10-year study by the Southern Appalachian Mountains Initiative (SAMI) concludes that local sources in the Southeast cause most of the haze in southern Appalachian mountains, contrary to the long-held belief that pollution drifted from the industrial Midwest. The report recommends a national approach to reduce sulfur dioxide and nitrogen oxide emissions from coal-fired power plants. SACE is referenced in the article's web resources section.
