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…

Will an Ozone Generator protect me and my family from COVID-19?
No, do not use ozone generators in occupied spaces. When used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants. Visit the Centers for Disease Control and Prevention's website for best practices to protect…

Can air cleaning devices that use bipolar ionization, including portable air cleaners and in-duct air cleaners used in HVAC systems, protect me from COVID-19?
Bipolar ionization (also called needlepoint bipolar ionization) is a technology that can be used in HVAC systems or portable air cleaners to generate positively and negatively charged particles. Provided manufacturers have data to demonstrate efficacy, manufacturers of these types of devices may market this technology to help remove viruses, including…

Will running an evaporative cooler (sometimes known as a "swamp cooler") or whole-house fan help protect me and my family from COVID-19?
Both evaporative coolers (or "swamp coolers") and whole-house fans can help protect people indoors from airborne transmission of COVID-19 because they increase ventilation with outside air to cool indoor spaces. Evaporative coolers are used in dry climates. They use water to provide cooling and increase relative humidity indoors. When operating…

Where can professionals who manage school, office, and commercial buildings get information on ventilation and filtration to respond to COVID-19?
Professionals who operate school, office, and commercial buildings should consult the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guidance for information on ventilation and filtration to help reduce risks from the virus that causes COVID-19. In general, increasing ventilation and filtration is usually appropriate; however, due to the…

Can a refiner or importer use gasoline sulfur test methods other than ASTM D 2622-98, especially for sulfur levels of 10 ppm and less?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The rule designates ASTM D 2622 as the benchmark test method by which compliance will be determined, and that is the test that the Agency typically will use in establishing compliance. However, the rule does permit alternative test…

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.

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…

Will an air cleaner or air purifier help protect me and my family from COVID-19 in my home?
When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, operating…

How can I increase ventilation at home to help protect my family from COVID-19?
Ensuring proper ventilation with outside air is a standard best practice for improving indoor air quality. However, by itself, increasing ventilation is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, increasing ventilation can be part…

Must a refinery that produces both California gasoline and federal RFG designate each batch produced as either federal RFG or California gasoline, and maintain segregation of both products, even though the gasoline meets the requirements of both programs?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Section 80.375(c) requires that each batch of California gasoline be designated as such by the refiner or importer, and that California gasoline be segregated from gasoline that is not California gasoline at all points in the distribution system…
