§ 86.304-79 - Section numbering; construction.  


Latest version.
  • (a) The model year of initial applicability is indicated by the section number. The two digits following the hyphen designate the first model year for which a section is effective. A section remains effective until superseded.

    Example: Section 86.311-79 applies to the 1979 and subsequent model years until superseded. If a §86.311-81 is promulgated it would take effect beginning with the 1981 model year; §86.311-79 would apply to model years 1979 and 1980.

    (b) A section reference without a model year suffix refers to the section applicable for the appropriate model year.

    (c) Unless indicated, all provisions in this subpart apply to both gasoline-fueled and Diesel heavy-duty engines.
