General Description

Summary of Federal Requirements

After 31 December 1995 gasoline may only contain lead additives of less than 0.05 g/gal.

If the dispensing facility is located in an area with an oxygenated gasoline program with a minimum oxygen content per 1 gal or minimum oxygen content requirements in conjunction with a credit program, each gasoline pump dispensing oxygenated gasoline at a retail outlet must have a label attached during the control period that states:

The gasoline dispensed from this pump is oxygenated and will reduce CO pollution from motor vehicles.

If the dispensing facility is located in an area with an oxygenated gasoline program with a credit program and no minimum oxygen content requirement, the fuel pump at a retail outlet in the control area has a label that states the following:

The fuel dispensed from this pump meets the requirements of the Clean Air Act as part of a program to reduce CO pollution from motor vehicles.

Diesel fuel for use in motor vehicles must:

• have a sulfur percentage, by weight, no greater than 0.05 percent
• have a cetane index of at least 40 or a maximum aromatic content of 35 volume percent
• is free of visible evidence of the dye solvent red 164, unless it is used in a manner that is tax-exempt as defined under section 4082 of the Internal Revenue Code (26 U.S.C. 4082).

At every retailer and whole sale purchaser-consumer, each pump from which gasoline or methanol is introduced into motor vehicles must be equipped with a nozzle that dispenses fuel at a flow rate not exceeding 10 gal/min. (NOTE: This requirement does not apply to pumps that are shown to be dedicated to heavy-duty vehicles, boats, or airplanes.)
