How is the reporting of ethanol production and/or biogenic emissions being handled in the rule?
Ethanol production facilities are not excluded from the rule. The sources of GHG emissions at ethanol production facilities that were to be reported under the proposed rule were stationary fuel combustion, onsite landfills, and onsite wastewater treatment. At this time, the Mandatory Reporting of Greenhouse Gases Rule does not require emissions from onsite industrial landfills and wastewater treatment to be reported (see Question 1). Stationary fuel combustion sources at ethanol production facilities are subject to the requirements of the rule if those emissions exceed the 25,000 metric tons CO2e threshold.
