New York State Thruway Authority
Selected Aspects of Alternative Fuel Vehicles: Purchases and Fueling

Issued: September 7, 2012
Link to full audit report 2011-S-15

To determine whether the New York State Thruway Authority (Authority) purchased alternative fuel vehicles in compliance with Executive Order 111 and used alternative fuels in these vehicles to obtain the intended benefits. This audit covers the period January 1, 2006 through September 30, 2011.

Executive Order 111 (Order) requires most State agencies and State public authorities (including the Authority) to shift purchases of light-duty vehicles to include alternative fuel vehicles. Starting in 2005, 50 percent of all new light-duty vehicle purchases were required to be alternative fuel, increasing to 100 percent in 2010. Between January 1, 2006 and June 6, 2011, the Authority purchased 731 light-duty vehicles, including 594 alternative fuel vehicles.

Key Findings

  • The Authority was not in compliance with the Order in 2006. It was in compliance from 2007 through 2011.
  • The Authority has not developed any policy or given guidance to its employees on when to use alternative fuel E-85 in its vehicles. As a result, fuel selection is driven by employee choice rather than Authority direction. For the three divisions we tested, Authority employees at locations with E-85 pumps used E-85 between 30 percent and 60 percent of the time.

Key Recommendations

  • Develop a policy based on a formal analysis of the benefits and drawbacks of different fuels, consistent with Authority priorities and available resources.
  • Provide guidance to Authority employees regarding the use of E-85 in the Authority's alternative fuel vehicles.
