Section 86.1313-2007 includes text that specifies requirements that differ from §§86.1313-94 and 86.1313-2004. Where a paragraph in §86.1313-94 or §86.1313-2004 is identical and applicable to §86.1313-2007, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved]. For guidance see §86.1313-94.” or “[Reserved]. For guidance see §86.1313-04.”.
(a) [Reserved]. For guidance see §86.1313-2004.
(b) heading and (b)(1) [Reserved]. For guidance see §86.1313-94.
(b)(2) Petroleum fuel for diesel engines meeting the specifications in Table N07-2, or substantially equivalent specifications approved by the Administrator, shall be used in exhaust emissions testing. The grade of petroleum fuel used shall be commercially designated as “Type 2-D” grade diesel fuel except that fuel commercially designated as “Type 1-D” grade diesel fuel may be substituted provided that the manufacturer has submitted evidence to the Administrator demonstrating to the Administrator's satisfaction that this fuel will be the predominant in-use fuel. Such evidence could include such things as copies of signed contracts from customers indicating the intent to purchase and use “Type 1-D” grade diesel fuel as the primary fuel for use in the engines or other evidence acceptable to the Administrator. (Note: Vehicles certified under §86.007-11(f) must be tested using the test fuel specified in §86.1313-2004, unless otherwise allowed by the Administrator.) Table N07-2 follows:
