I'm an expert in the field of fuel technology and regulations, with a particular focus on diesel fuels and their environmental impacts. Diesel fuels are a critical component of our transportation and industrial sectors, and understanding their composition and regulations is essential for both environmental protection and operational efficiency.
Ultra low sulfur diesel (ULSD) is a type of diesel fuel that has been refined to reduce the sulfur content to extremely low levels. The sulfur content in ULSD is less than 15 parts per million (ppm), which is a significant reduction from the previous standard of 500 ppm. This reduction in sulfur content is crucial for reducing emissions and meeting environmental regulations.
The dye used in diesel fuel serves several purposes. It helps to distinguish different types of diesel fuel for tax and regulatory purposes. For instance, red-dyed diesel is typically used for off-road and non-highway applications, and it is often tax-exempt. This type of diesel is dyed red to differentiate it from clear diesel, which is used for on-road vehicles and is subject to taxes.
As of October 1, 2014, the Environmental Protection Agency (EPA) in the United States mandated that red-dyed, tax-exempt diesel fuel for non-road use must have a sulfur content of less than 15 ppm. This regulation was put in place to further reduce emissions and improve air quality. Red-dyed diesel fuel with less than 15 ppm sulfur content was already available in the U.S. market by April 11, 2014, indicating that the industry had already begun to adapt to the new standards.
It is important to note that the dye itself does not affect the sulfur content of the diesel fuel. The dye is simply a visual indicator used for identification and regulatory compliance. The sulfur content is determined by the refining process, and the EPA's regulations ensure that ULSD meets the required environmental standards.
In summary, ULSD is dyed for identification and regulatory purposes, but the dye does not influence the sulfur content of the fuel. The sulfur content is regulated to be ultra low, specifically less than 15 ppm, to meet stringent environmental standards and reduce harmful emissions.

By October 1, 2014, the EPA will require red-dyed, tax-exempt diesel fuel for non-road use to have a sulfur content of less than 15 ppm. Red-dyed diesel fuel with sulfur content less than 15 ppm is already available today in the U.S. marketplace.Apr 11, 2014
