While there is no renewable fuel obligation under the RFS2 program for the production or importation of conventional jet fuel, RINs can be generated for renewable jet fuel. Is that right?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . As described in 80.1407, only gasoline and diesel fuels produced or imported into the U.S. are subject to the renewable fuel standards. Thus, only gasoline and diesel fuel volumes produced or imported by an obligated party factor into…

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…

How are people potentially exposed to nitrate?
For many situations, the potential for children’s exposure from drinking water is medium to low. The potential can be higher when private wells become contaminated with nitrates from feed lot and agricultural runoff, and contaminated groundwater. Some geographic areas are at higher risk of drinking water contamination of private wells…

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…
