Administrative Record Index

To request copies of administrative record documents, an electronic order form is available.

The documents contained in this administrative record file were used by the U.S. Environmental Protection Agency in identifying appropriate remedial activities for use at the Koppers Co., Inc. Superfund site in Oroville, California. These documents are available in the repositories at the Merian Library of Cal. State University at Chico, at Butte County Public Library in Oroville and in the Region 9 Superfund Records Center in San Francisco.
The Koppers administrative record includes an initial set of documents compiled in December 1988 and seven supplements, or additional sets of documents, added since that time. All of these documents have been microfilmed. A brief description of each of these groups of documents is provided below:

GroupAR Doc.#FormatDescription
Initial1-376microfilmArranged chronologically from
9/26/83 to 8/22/88, with undated
documents at the end of the sequence.
Suppl.1377-512microfilmArranged chronologically from 4/7/86 to 8/29/89. The initial group and this supplement were the basis for the 1989 ROD as well as the actions taken in response to the 1987 fire at the site. Documents related to the post-fire removal action are indicated in the index by an(R) below each document number.
Suppl.2 513 & 514microfilmConsists of the 1989 Record of
Decision (ROD) and the 1991
Explanation of Significant Differences
(i.e., minor modifications to the
ROD).
Suppl.3515&516microfilmIncludes the Consent Decree
requiring Beazer East, Inc. to
implement the 1989 ROD.
Suppl.4517-737microfilmPost-ROD documents that support
the March 1996 proposed plan
Suppl.5738-750microfilmPost-ROD documents, including the
Site-Wide Soils Remedy Report, that
support the March 1996 proposed plan.
Suppl.6751-764microfilmDocuments received or prepared
after the proposed plan was issued
- including the ROD amendment.
Suppl.7765-1054microfilmPost-ROD documents that support the
1998 proposed plan - amendment #2 to
the ROD for soil and groundwater.
Suppl. 81055-1089microfilmDocuments received or prepared after the proposed plan was issued, including ROD amendment #2.


In addition to the documents described above, a separate administrative record was prepared for the removal action undertaken in 1994 for dioxin-contaminated soil. This removal action AR, contained in two looseleaf binders, is considered to be part of the cumulative AR that was used by EPA in identifying response activities at the site. It is also available in this library.

For ease of use, the indexes for the initial compilation and the eight supplements have been combined to produce a cumulative index that is presented in two formats. The first format lists the documents in AR number order, which reflects the arrangement of the documents in the file. When you are scrolling through the microfilm, the index in AR number order will be most useful for you. The second format lists the documents in ascending chronological order. When you know the date of a particular document you want to look at, use the chronological index. Both indexes contain exactly the same information.

The list of U.S. Environmental Protection Agency guidance documents which were considered or relied upon in the selection of the remedy is document AR 1089 in this administrative record file. Copies of the guidance documents are contained in the Compendium of CERCLA Response Selection Guidance Documents located in the Region 9 Superfund Records Center.

The administrative record file will continue to be added to as documents become available. It will be complete after public comments on EPA's Proposed Plan, EPA's response to comments, and the Record of Decision (ROD) are included.
