ULSDF refers to diesel fuel that has a sulfur content of no more than fifteen parts per million. BART means the use of technology, verified by the United States Environmental Protection Agency (USEPA) or the California Air Resources Board (CARB), to reduce the emission of pollutants into the air. Such technology must also, at a reasonable cost achieve the greatest reduction in emissions of nitrogen oxides (it should not cost thirty percent more than other technology applicable to the particular engine).
Failure to comply with the rules concerning the use of emissions control technology on school buses might result in significant financial penalties, ranging from $1,000 to $10,000, as set forth in the Rules of the City of New York (RCNY) Title 15, Air Code Penalty Schedule.
