E15 retailers from across the country are urging President Trump to ensure the Environmental Protection Agency follows through on his commitment to allow fuel containing 15 percent ethanol to be sold year-round. “This common-sense change will allow us the opportunity to consistently offer a less expensive, higher performing fuel to our consumers at stations across America,” the companies stated in their letter to the president. Growth Energy CEO Emily Skor said that the outdated regulation not only hurts consumers by removing a cleaner, more cost-efficient fuel option during the summer driver season but also harms businesses. The retailers also urged the president to avoid implementing a cap on the price of Renewable Identification Numbers under the Renewable Fuel Standard and curtail the rapid expansion of so-called small refinery “hardship” waivers.
