May I generate RINs that I produced and sold for non-road use in the past so that I can reinstate those RINs under RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Section 80.1426(c)(2) provides that RINs are assigned to a volume of renewable fuel when ownership of the RIN is transferred along with ownership of the volume of renewable fuel. A comparable provision appear in the RFS1 regulations, at…

What sources make up the Tier 1 categories used in the emissions trends?
Tier 1 categories are assigned by source classification codes (SCCs) that are the most specific processes available in the NEI. The latest SCC list with the Tier 1 assignments can be downloaded from the EPA SCC website in Comma Separate Values (CSV) format.

What is the cause of the large decrease in electric utility emissions, particularly sulfur dioxide, starting in 1995?
SO2 emissions reductions from utilities during this time are primarily attributed to the impacts of the acid rain program. As described on EPA’s Acid Rain Program web page, Phase 1 of this program began in 1995 and affected 263 units at 110 most coal-burning electric utility plants in 21 eastern…

SPCC Rule schedules for inspections, tests, and evaluations
The SPCC rule requires inspections, tests, and evaluations of above ground containers (40 CFR §112.8(c)(6)). Does the rule set schedules for how often these need to be conducted? The SPCC Rule does not prescribe a specific frequency or methodology for performing the required inspections, evaluations, and tests for aboveground containers…

May I generate RINs for renewable fuel that I produced and sold for non-motor vehicle use in the past so that I can reinstate those RINs under RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . No. RINs that were previously generated in 2009 and 2010 may be reinstated if they were retired for non-motor vehicle use. However, RINs may not be generated for renewable fuel produced in the past in order to retire…

Are mobile refuelers exempt from integrity testing requirements?
Pursuant to 40 CFR §112.8(c)(2), mobile refuelers are exempt from the secondary containment requirements for bulk storage containers. Are mobile refuelers also exempt from the requirements for integrity testing in §112.8(c)(6)? Since mobile refuelers are mobile or portable bulk storage containers, the other provisions of §112.8(c) still apply. Therefore, mobile…

In addition to 2009 RINs, may a party reinstate 2008 and 2010 RINs that were retired for non-road use under RFS1?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Pursuant to §80.1429(g), any 2009 RINs that were retired for non-motor vehicle, heating oil or jet fuel use under RFS1 may be reinstated under RFS2. The regulations do not allow 2008 RINs to be reinstated. Since RFS1 RINs…

How does a retiring party reinstate RFS1 RINs that were retired because renewable fuel was ultimately used for non-motor vehicle, heating oil or jet fuel purposes? What steps are required to be taken and do any codes require changing?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Pursuant to §80.1429(g), parties may reinstate 2009 RINs that were retired under RFS1 because the renewable fuel was ultimately used in a non-motor vehicle application, heating oil or jet fuel. As stated in question 11.1, since RFS1 RINs…

Why do mobile source NOx emissions jump higher between 2001 and 2002 on the emissions trends?
The emissions model used for mobile sources changed from MOBILE6.2 to MOVES 2010 in December 2009. This change included a notable increase in NOx emissions. The EPA adjusted data back to 2002 to reflect the change in models. The higher emissions in 2002 are because of this method change and…

Why do the PM2.5 emissions for the electric utilities source category jump up between 1998 and 1999?
The estimation method for PM emissions from fuel combustion sources was enhanced beginning with the 1999 National Emissions Inventory. Prior to 1999, the emissions measurement data methodology only included the filterable portion (which means the solid particle matter at elevated stack temperatures). Beginning with the 1999 NEI, both the filterable…
