U.S. EPA has asked for comments on how to account for greenhouse gas emissions generated from bioenergy and other biogenic sources. It stated: "The fact that the Tailoring Rule did not take final action one way or another concerning such an exclusion does not mean that EPA has decided there is no basis for treating biomass CO2 emissions differently from fossil fuel CO2 emissions under the Clean Air Act’s PSD and Title V Programs."
Comments are due September 13, 2010.
