emissions included in the analysis and are seeking comments on our methodology as wellas various options for determining the lifecycle greenhouse gas emissions (GHG) foreach fuel. In addition to seeking comments on the information in this document and itssupporting materials, the Agency is conducting peer reviews of critical aspects of thelifecycle methodology. The increased use of renewable fuels would also impact criteriapollutant emissions, with some pollutants such as volatile organic compounds (VOC) andnitrogen oxides (NOx) expected to increase and other pollutants such as carbon monoxide(CO) and benzene expected to decrease. The production of feedstocks used to producerenewable fuels is also expected to impact water quality.This action proposes regulations designed to ensure that refiners, blenders, andimporters of gasoline and diesel would use enough renewable fuel each year so that thefour volume requirements of the Energy Independence and Security Act would be metwith renewable fuels that also meet the required lifecycle greenhouse gas emissionsperformance standards. Our proposed rule describes the standards that would apply tothese parties and the renewable fuels that would qualify for compliance. The proposedregulations make a number of changes to the current Renewable Fuel Standard programwhile retaining many elements of the compliance and trading system already in place.2
