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 80.1401…

How does PBATMA (40 CFR 80.47) apply to refiners and importers of “California gasoline” subject to the enforcement exemptions of 40 CFR 80.81?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Refiners and importers of California gasoline that is subject to the enforcement exemptions of 40 CFR §80.81 may continue to use sampling and testing methodologies as described in paragraph §80.81(h).

The sulfur rule says that a small refiner must produce gasoline by processing crude oil through a refinery processing unit. Does our refinery meet that requirement if we produce gasoline by processing crude oil through a processing unit, but we sometimes
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Under § 80.225(a), a small refiner is a refiner who processes crude oil through refinery processing units, employed an average of no more than 1,500 people during 1998, and had an average crude capacity less than or equal to…

See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Section 80.340(b)(1) provides that butane blenders may comply with the gasoline sulfur rule sampling and testing requirements using test results from the butane supplier provided that certain requirements are met. One requirement is that the sulfur content of the…

What test requirements exist for determination of the sulfur content of denatured ethanol? What test method must be used to determine the sulfur content of ethanol? In the absence of an approved test method, what guidance can the Agency provide fuel ethan
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The regulations do not require an ethanol blender, producer or supplier to test ethanol for sulfur content. The regulations do prohibit blending denatured ethanol into gasoline if the sulfur content of the denatured ethanol exceeds 30 ppm. See §…

Can product codes satisfy the product transfer documentation requirements set forth at 40 C.F.R. 80.1503(a)?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. EPA believes that parties normally are able to meet the product transfer requirements by including the required information in the documents that the parties currently use to memorialize the transfer of title or custody of the gasoline. Product codes…
-
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 the…

There is significant difference between "refiner" and "refinery". Portions of the regulations use "refiner" where "refinery" is the appropriate term. While it may be clear from the context that "refinery" is meant, text should be changed to avoid any poss
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. We agree with the comment and intend to make these clarifications in a future rulemaking. These clarifications would not affect the regulatory requirements in the current final rule.

Does the gasoline sulfur rule require refiners and downstream parties to account for the sulfur content of a registered fuel additive, such as a corrosion inhibitor used to help prevent sulfur-related fuel gauge sending unit failures?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Currently, there is no requirement under the gasoline sulfur rule for refiners or downstream parties to demonstrate compliance with the gasoline sulfur standards for registered fuel additives. Parties who add fuel additives, however, are responsible for ensuring that the…

Is corn oil extracted from distiller?s grains and solubles (DGS) eligible for RINs under RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Biodiesel or renewable diesel made from non-food grade corn oil extracted from DGS that is made from renewable biomass is eligible to generate RINs. See Table 1 to 80.1426.
