This webpage provides resources developed by the ASTSWMO Emerging Fuels Task Force and others to assist State UST programs.
The Emerging Fuels Task Force developed this report as an update and replacement to the 2013 ASTSWMO Alternative Fuels Workgroup’s Compatibility of UST Systems with Biofuels report. This document serves as a resource for State and Territorial underground storage tank (UST) program staff, UST owners and operators, equipment manufacturers, and contractors and consultants for the evaluation of equipment compatibility pursuant with EPA’s compatibility requirement (40 CFR 280.32) specifically when storing motor fuels. The document includes information product and operational compatibility, properties of biofuel blends, and considerations for the storage of biofuel blends. Also included are several policy and technical resources, a template for creating a compatibility evaluation checklist for State programs, and a compilation of case summaries from several States.
