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.
