South Dakota's ethanol industry is responsible for a smaller share of pollution from cancer-causing chemicals.
Federal Environmental Protection Agency data shows the ethanol industry was accountable for 40 percent of reported releases of cancer-causing chemicals last year, down 4 percent from 2009.
Officials say one of the reported chemicals is a byproduct of grain distillation and it's less toxic than many other substances.
