EPA  Finalizes Modifications to the
                    Transmix Provisions Under the Diesel
                    Sulfur Program
                    E
        PA is issuing a Final Rule to amend the Transmix Provisions
        Under the Diesel Fuel Program.
                    Overview
                    EPA is amending the requirements under EPA's diesel sulfur program related to the
                    sulfur content of locomotive and marine (LM) diesel fuel produced by transmix
                    processors and pipeline facilities. These amendments will reinstate the ability of
                    locomotive and marine diesel fuel produced from transmix by transmix processors
                    and pipeline operators to meet a maximum 500 parts per million (ppm) sulfur stan-
                    dard outside of the Northeast Mid-Atlantic Area and Alaska and expand this ability
                    to within the Northeast Mid-Atlantic Area provided that: the fuel is used in older
                    technology locomotive and marine engines that do not require 15 ppm sulfur diesel
                    fuel, and the fuel is kept segregated from other fuel. These amendments will provide
                    significant regulatory relief for transmix processors and pipeline operators to allow
                    the petroleum distribution system to function efficiently while continuing to transi-
                    tion the market to virtually all ultra-low sulfur diesel fuel (ULSD, i.e. 15 ppm sulfur
                    diesel fuel) and the environmental benefits it provides.
