Notes:
a   Standards effective January 1 at the refinery gate.
b   No Refinery Average Standard applies in 2004; Corporate
    Average Standard applies in 2004 (120 ppm) and 2005
    (90 ppm).
c   Cap exceedances up to 50 ppm in 2004 must be made up
    in 2005.
d   Geographic Phase-in Area (GPA) refiners must also com-
    ply with the corporate average standards in 2004 and 2005
    if less than 50% of the refiner's gasoline is designated as
    GPA gasoline in a given compliance period.
e   GPA refiners may receive an additional two years (i.e.,
    through 2008) to comply with the 30 / 80  ppm gasoline
    sulfur standards in exchange for producing 95% of their
    highway diesel fuel at the 15 ppm sulfur standard by June
    1,2006.
f   Small refiners may receive an additional two years (i.e.,
    through 2009) to comply with the 30 / 80  ppm gasoline
    sulfur standards via a hardship demonstration.
                                               Small refiners may receive an additional three years (i.e.,
                                               through 2010) to comply with the 30 / 80 ppm gasoline
                                               sulfur standards in exchange for producing 95% of their
                                               highway diesel fuel at the 15 ppm sulfur standard by June
                                               1,2006.
                                               Small refiners may receive a 20% increase in their annual
                                               average and per-gallon cap standards in exchange for
                                               producing 95% of their highway, nonroad,  locomotive, and
                                               marine diesel fuel at the 15 ppm sulfur standard by June 1,
                                               2006.
                                               Downstream standards are effective February 1 at any
                                               downstream location other than at a retail  outlet or whole-
                                               sale purchaser-consumer (e.g., pipelines and terminals)
                                               and March 1 at any downstream location.
                                               Downstream standards for gasoline that is not blended
                                               with small refiner gasoline are shown.  Refer to the Code
                                               of Federal Regulations (CFR) for the downstream stan-
                                               dards that apply when a gasoline blend includes small
                                               refiner gasoline.
