Emerging Fuels Resources

This webpage provides resources developed by the ASTSWMO Emerging Fuels Task Force and others to assist State underground storage tank programs.

ASTSWMO Compatibility Considerations for Underground Storage Tank Systems

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.

ASTSWMO State Compatibility Compendium

The ASTSWMO Emerging Fuels Task Force developed a survey in 2014 to understand existing UST infrastructure, develop a compendium for State policies and activities specific to biofuels and other emerging fuel types and to help provide a framework for identifying similarities and differences between State programs. If your State has updates to the data in the compendium, please send them to ASTSWMO staff or the Emerging Fuels Task Force representative for your region.

ASTSWMO Compatibility Toolkit: ASTSWMO is developing an interactive tool to assist users in identifying UST system components that are compatible with specific motor fuels. The majority of the information included comes directly from equipment manufacturers and ASTSWMO is not responsible for the accuracy or completeness of any information provided by other parties.

ASTSWMO Corrosion Observations Tool: Users will be able to use this tool to submit system corrosion observations. The tool will request fuel type and age of component, and allow for users to submit photographs and additional information on their observations.
