The oil and gas lobby is threatening to sue the Obama administration if environmental regulators do not release a biofuel regulation by the end of November.
The American Petroleum Institute (API) on Thursday sent a letter notifying the Environmental Protection Agency that it should prepare for a lawsuit if the final 2014 renewable fuel standard is not released on time.
The fuel standard calls for refiners to mix increasing amounts of biofuel in with conventional gasoline.
It was developed as a way to wean the country off of foreign sources of oil and spur innovation in developing new fuel sources.
The oil and gas industry, however, claims that the demand has become overly stringent, and that it calls for refiners to produce a blend of gasoline that consumers don’t want and can’t use.
They have also complained that the EPA has consistently been late in finalizing the yearly standard.
