Can a gallon of ethanol generate more than 1.0 RIN in RFS2?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The number of RINs that can be generated for each gallon of renewable fuel are determined by the Equivalence Values. See 80.1415 and 80.1426(f)(2)-(6). Equivalence Values are based on energy content in the renewable fuel in comparison to…

If I produce biodiesel using waste vegetable oil, can I generate more RINs per gallon than if I use virgin soy oil? Would the use of solar panels as a heat source for our process help with our RIN number per gallon?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The number of RINs that can be generated for each gallon of renewable fuel is determined by the Equivalence Values. See regulations at 80.1415(b) and 8.1426(f)(2)(i), for example. Equivalence Values are based on energy content in the renewable…

What is the operational tolerance for denaturant in ethanol to meet the definition of Renewable Fuel? The RFS2 definition calls for a maximum of 2% denaturant. What if the lab results come back higher or lower than 2%? For example, what if the lab results
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The definition of renewable fuel in 80.1401 specifies that the maximum amount of denaturant in ethanol that can be treated as renewable fuel is 2 volume percent. If lab results indicate that the concentration of denaturant is higher…

If a certified inspector or risk assessor determines that a component was installed post-1978 and is therefore free of lead-based paint, can the renovation firm rely on this determination?
Yes, as long as the renovation firm has obtained a copy of the determination. The firm must retain a copy of the determination for three years after completion of the renovation. Question Number: 23002-18218 Find a printable PDF copy of all frequent questions pertaining to lead .

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…

Where is more information available about emissions estimation methods used by the EPA?
For criteria air pollutants and precursors as well as for hazardous air pollutants, the methods are described in the technical support document (TSD) for the latest National Emissions Inventory (NEI) available from the main NEI page . For greenhouse gas emissions, you can find greenhouse gas inventory methods from the…

If a producer is able to change its D code, can it make retroactive changes in the D code of the RINs it has issued previously during the year or earlier if the production during the previous period would meet the newly classified D code criteria?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Once a RIN is generated and transferred to another party, it cannot be changed. Thus, retroactive changes to D codes in RINs are not allowed.

Is a lead-based paint inspection sufficient to determine compliance with requirements of the RRP rule?
Question: Is a lead-based paint inspection, performed by a certified inspector or risk assessor, that includes a written determination that various building components are free of paint or other surface coatings containing lead equal to or in excess of 1.0 milligrams per square centimeter (mg/cm2) or 0.5% by weight sufficient…

When testing a property for the presence of lead prior to beginning a renovation using an EPA-recognized lead test kit, must I test every component affected by the renovation?
Answer: Yes. Because certified renovator training does not cover sampling protocols, certified renovators using EPA-recognized lead test kits or performing paint chip sampling to determine the applicability of the RRP Rule must test each and every component that will be affected in order to determine that the RRP Rule does…

How are emissions trends compiled?
For criteria air pollutants and precursors, the emissions trends are based on the triennial National Emissions Inventory data, with some interim year data included for non-triennial years. The methods and interim-year approaches are described on the “Development of Data” tab included with the data provided on the Air Pollutant Emissions…

How do I determine what SCCs have changed between inventory years?
These are available in the EIS (Reporting Code table) or public website: https://sor-scc-api.epa.gov/sccwebservices/sccsearch/ Filter on “last inventory year” to remove SCCs no longer active. If this column has a date in it, then the SCC has been retired as of that date. The “last updated date” (column J) indicates when…

Does ethanol derived from cellulosic feedstock or sugar have the same Equivalence Value as ethanol derived form corn starch, i.e. 1.0?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Yes. Equivalence Values are based on energy content in the fuel, adjusted for renewable content in comparison to denatured ethanol. See 80.1415(c). Ethanol from starch, sugar, and cellulose is all chemically identical, and is all 100% renewable (none…
