Biodiesel Fueling Infrastructure Development

There is much to consider when building biodiesel fueling infrastructure. Use these resources as spring boards to getting started. Minimal B20 and B100 equipment listed by Underwriters Laboratories (UL) is available for dispensing equipment. Above-ground manufacturers (dispensers and hanging hardware) are expected to offer more B20 listed equipment in 2013.

Existing Tanks

Using biodiesel in existing petroleum fuel storage tanks requires some tank preparation and adherence to EPA guidance.

Underground Tanks

In 2011, EPA issued a guidance for the storage of biofuel blends in existing underground storage tanks (UST). The guidance provides a method for alternative compliance because many tanks were listed prior to the widespread use of biofuels. The guidance requires UST manufacturers to provide a statement of compatibility for their products with specific biofuels blends. All tank manufacturers have issued statements of compatibility with blends of up to 100% biodiesel. UST compatibility statements are available from the Petroleum Equipment Institute and the Steel Tank Institute. EPA UST regulations are implemented by individual state agencies.

Above-Ground Tanks

Above-ground tank manufacturers have also provided statements of compatibility with all biodiesel blends.

Tank Preparation

Existing tanks and lines must be thoroughly cleaned prior to storing B20. B20 will "clean out" and absorb contamination left behind by years of petroleum fuel storage. Some tanks might need to be replaced completely.

Biodiesel Handling and Use

Fleets that use biodiesel must understand biodiesel fuel specifications and the proper ways to handle and store the fuel. Here is a summary of key handling and use guidelines.
