  • What is the purpose of a cellulosic biofuel waiver credit?

    See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Under EISA, EPA is required to make cellulosic biofuel waiver credits available for years where we waive some portion of the statutory volume for cellulosic biofuel. These credits can then be used by obligated parties to comply with…

  • Are mobile refuelers exempt from integrity testing requirements?

    Pursuant to 40 CFR §112.8(c)(2), mobile refuelers are exempt from the secondary containment requirements for bulk storage containers. Are mobile refuelers also exempt from the requirements for integrity testing in §112.8(c)(6)? Since mobile refuelers are mobile or portable bulk storage containers, the other provisions of §112.8(c) still apply. Therefore, mobile…
