Yes, the EPA regulations require that the sulfur content of all diesel dispensers in the United States, except California, be communicated to the diesel end-users, using new dispenser labels. This includes the S15 (ULSD), S500 (LSD), and S5000 (HSD) dispensers. This regulation applies to any dispenser; whether it is at a retail site, commercial site, or is for company's own use.

In California, the state has mandated that ULSD be the only fuel available. Therefore, the EPA has exempted California from labeling dispenser pumps.
