but also the preamble of the 1988 proposed rule. In order to
produce a useful reference tool, we are carrying out an eight-week
field test and wouldtappreciate your participation in putting the
index to use. By September 28th, please provide your comments and
suggestions in writing to the attention of Rhea Cohen, Chief,

A Note to the Reader
This document is composed of two parts. Part I is an index of key terms. The selection of terms
included was based on our experience and knowledge gained over the last several years on the NCP
revision project, and we have sought to be as comprehensive as possible. The primary references included
are to the NCP final rule and preamble (54 FR 8666, March 8, 1990). Part I also contains selected
references to the preamble of the proposed NCP (53 FR 51394, December 21,1988). These latter
references are more general, and highlight only certain sections of the preamble where a term is discussed;
these references are not intended to be as comprehensive as those for the final rule and preamble and not
every proposed rule preamble reference to a. particular term is included. As noted in the final rule
preamble, the preambles to both the proposed and final rules should be consulted when issues arise on the
meaning or intent of the final rule. Unless directly contradicted or superseded by the final rule and
preamble, the preamble to the proposed rule reflects EPA's intent in promulgating the final rule.
The references contained in this index appear in three different ways in the following order,
depending on the source referenced:
•	References to the preamble of the final NCP appear in regular, non-bold type. For
example, pages 8769-8770 always appear in regular type.
•	References to the rule language of the final NCP appear in bold type. For example, pages
8830-8831 always appear in bold.
•	References to the preamble of the proposed NCP appear with full Federal Register
references. For example, 51 F£ 51459 refers to the preamble to the proposed NCP.
To provide the most precise and detailed references possible, this index uses subheadings wherever
appropriate. It also makes free use of cross references that permit the user to search for a term several
different ways. In all cases, subheadings appear in italics, which should assist the reader when searching
for a cross-referenced term; if the cross reference includes italics, it refers to a subheading under another
main entry.
Part II of this document is a series of three tables of contents addressing the NCP proposed rule
preamble (Section A), the NCP final rule preamble (Section B), and the NCP final rule (Section C),
respectively. The tables provide specific Federal Register page references to the subpart and section
discussions that are included in the three sources.
Please direct any comments or suggestions regarding this document to Rhea Cohen, Office of
Emergency and Remedial Response, Policy and Analysis Staff (OS-240), 401 M Street, SW, Washington,
DC 20460 (telephone (202) 382-2200 or FTS 382-2200).
