| 摘要： | The outline for this document is identical to the outline used in the preamble to our proposed rule (72 FR 3200). We have summarized comments and placed those comments under the heading which most accurately characterized the nature of the comment. As such, issues can be identified by section number within which those issues have been placed. The reader should keep in mind that we have attempted to place a comment into only one issue area or section number within this document. For example, we received comments pertinent to threshold levels and/or feasibility of our proposal with respect to heavy-duty OBD on applications under 14,000 pounds (see section II.H). However, in section I.B.3 of this document, we note that we received no comments pertinent to section I.B.3 which was the preamble section that provided an overview of our proposed requirements for OBD on applications under 14,000 pounds. We make such a note since no one commented on that overview section and, instead, we have summarized the comments and made our responses under section II.H. |
