Please clarify whether oxygenates blended into either conventional gasoline or Reformulated Blendstock for Oxygenate Blending (RBOB) downstream of the refinery need to be included in sulfur compliance calculations.
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Section 80.205(c) provides that a refiner or importer may include oxygenates added downstream from the refinery or import facility if the requirements under § 80.69(a) or § 80.101(d)(4)(ii) of the RFG/CG regulations are met. Therefore, a refiner or…

In the NPRM, the sulfur standards were expressed without decimal places, but the final rule provides that the standards are expressed with two decimal places (§§ 80.195, 205). Why did EPA include this change?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . EPA included the decimal places to ensure that the sulfur standards are not exceeded by rounding down actual average sulfur levels. We do not believe reporting the average sulfur level to two decimals creates any additional burden as…

How complete are the data in the National Emissions Inventory?
While the goal of the National Emissions Inventory (NEI) program is to include all emissions data, there are always challenges meeting this goal. The answer about completeness of coverage of sources depends on the emissions sector and pollutant. In general, the criteria air pollutants and precursors (CAPs) are expected to…

If a facility is grandfathered, is it also exempt from the requirement that feedstocks must be renewable biomass?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Even if a facility is exempt from the 20% GHG reduction requirement, in order to generate RINs, the facility is still required to use feedstocks that meet the definition of renewable biomass. The definition of renewable fuel in…
