EPA considers options for E15 labels, USTs
New E15 fuel dispenser labels could soon be appearing at a gas pump near you. In January, EPA proposed updates to the fuel dispenser labeling requirements. E15 is gasoline that can contain up to 15 percent ethanol that is becoming more popular at retail gas stations. Currently, labels are required for gasoline-ethanol blends of greater than 10 percent volume ethanol and up to 15 percent ethanol. The point of the label is to alert consumers about the blend — particularly because engines older than MY2000 are not designed to run on ethanol blends. The agency is considering either modifying the E15 label or removing the labeling requirement altogether. EPA is also asking for comments on whether it should prohibit states and local governments from requiring different labels on fuel dispensers.
At the same time, EPA proposed modifications to the underground storage tank (UST) regulations to ensure the safe storage of E15 and higher gasoline blends at gas stations’ existing underground tank systems. The agency would require that all new UST systems installed, or all replacement parts for existing USTs, would be compatible with ethanol blends up to 100 percent. E15 tends to be more corrosive and can quickly degrade USTs that were not designed to store it. However, EPA is also proposing to allow USTs with secondarily contained tanks and pipes to continue storing E15 and higher ethanol blends, as long as they also have robust leak detection systems in place.
