- EPA allows dirtier ethanol production by relaxing environmental rules
Oct 23rd 2006 by Derrick Y. Noh
"Under existing rules, ethanol plants are considered major sources of air pollution if they emit more than 100 tons of toxic chemicals per year...Most new refineries are expected to emit just below the 250 ton limit...Some environmental groups believe that one of the primary motives behind the rule change is to allow a switch to coal for ethanol production."
