On August 10, 2015, Governor Chris Christie (R-NJ) signed into law S.B. 2599/A-4121, an act concerning the definition of certain fuels and amending P.L.2010, c.22. The legislation clarifies New Jersey's Motor Fuel Tax Act exemptions to include biofuels made from recycled grease, plants, and animal fats. In addition, biobased liquid fuel and biodiesel fuel are now defined as renewable biomass. The clarification of the biofuel tax exemption is intended to encourage biodiesel businesses to invest in New Jersey now that they can be certain that they qualify for tax exemptions. The bipartisan bill was passed unanimously by the New Jersey Assembly on June 25, 2015.
