Summary

Highlight any text to annotate
Ethanol Access for a Sustainable Economy Act of 2022 or the EASE Act of 2022 This bill revises the Reid Vapor Pressure (RVP) requirements to provide for the year-round sale of ethanol-gasoline fuel blends that contain more than 10% denatured anhydrous ethanol. RVP is a metric of gasoline volatility (i.e., how quickly fuel evaporates into the atmosphere). Current law prohibits the sale of gasoline that exceed certain RVP limits during the high ozone season (i.e., the summer months). However, current law provides waivers from this requirement, including a waiver that gives certain ethanol-gasoline fuel blends containing 10% denatured anhydrous ethanol a higher RVP limit under certain conditions. This bill expands the waiver to include ethanol-gasoline fuel blends containing more than 10% of such ethanol, thus allowing year-round sales of such fuel blends.
