Massachusetts has set the stage for making the transition from fossil fuels to biofuels in diesel and No.2 oil-fired applications, which includes biodiesel and ethanol E85, under Bulletin 13,

Establishment of Minimum Requirements for Bio-Fuel Usage in State Vehicles and Buildings by Executive Agencies pdf format of anf_administrativebulletin13.pdf

Bulletin 13, issued in 2006, directs all agencies of the Commonwealth to do the following:

  • Use a minimum of 5% biodiesel in both on-road and off-road diesel engines, beginning in Fiscal Year 2008
  • Use a minimum of 15% biodiesel in both on-road and off-road diesel engines, by Fiscal Year 2010
  • Set minimum-percentage requirements for E85 usage in state flex-fuel vehicles

Biofuel Implementation Plan

To support this transition, the Department of Energy Resources, in conjunction with the Executive Office of Energy and Environmental Affairs and the Operational Services Division (OSD), developed a Biofuels Infrastructure Plan pdf format of cc-bio-13-plan.pdf
. All Massachusetts agencies that operate diesel engines, on road, off road, and marine are expected to comply; however, they can request waivers if biodiesel is logistically unworkable for specific situations. Agencies with onsite diesel fueling tanks and dispensing systems can purchase biodiesel at a minimum of the 5% blend at the first filling of the tanks.

Biodiesel Purchasing Contract

OSD has a statewide biodiesel contract, ENE23, which is open to all eligible public entities, including cities and towns in the Commonwealth, to facilitate the purchase of these fuels.
