PREAMBLE

The purpose of this document is to provide the public with an index to the Administrative

Record File (AR File) for the U.S. Environmental Protection Agency’s (EPA) selected remedial

action to respond to conditions at the Ruston Foundry Superfund site (the “Site”). EPA’s action is

authorized by the Comprehensive Environmental Response, Compensation, and Liability Act

(CERCLA), 42 U.S.C. Section 9601 et seq. 

Section 113 (j)(1) of CERCLA, 42 U.S.C. Section 9613 (j)(1), provides that judicial review

of the adequacy of a CERCLA response action shall be limited to the Administrative Record (AR).

Section 113 (k)(1) of CERCLA, 42 U.S.C. Section 9613 (k)(1), requires the EPA to establish an AR

upon which it shall base the selection of its remedial actions. As the EPA decides what to do at the

site of a release of hazardous substances, it compiles documents concerning the site and it’s decision

into an “AR File.” This means that documents may be added to the AR File from time to time.

After the EPA Regional Administrator or the Administrator’s delegate signs the Action

Memorandum or the Record of Decision memorializing the selection of the action, the documents

which form the basis for the selection of the response action are then known as the Administrative

Record “AR.”

Section 113(k)(1) of CERCLA requires the EPA to make the AR File available to the public

at or near the site of the response action. Accordingly, the EPA has established a repository where

the AR File may be reviewed near the Site at:

Rapides Parish Library

411 Washington Street

Alexandria, LA 71301

Contact: Steve Rogge

(318) 442-1840 ext 238

and

Louisiana Department of Environmental Quality - 

Remediation Services Division

602 N. Fifth, 

Baton Rouge, LA 70802

Contact: Keith Casanova

(225) 219-3192

The public also may review the AR File at the EPA Region 6 office in Dallas, Texas, by

contacting the Remedial Project Manager at the address listed below. The AR File is available for

public review during normal business hours. The AR File is treated as a non-circulating reference

document. Any document in the AR File may be photocopied according to the procedures used at

the repository or at the EPA Region 6 office. This index and the AR File were compiled in

accordance with the EPA’s Final Guidance on Administrative Records for Selecting CERCLA

Response Actions, Office of Solid Waste and Emergency Response (OSWER) Directive Number

9833.3A1 (December 3, 1990).

Documents listed as bibliographic sources for other documents in the AR File might not be

listed separately in the index. Where a document is listed in the index but not located among the

documents which the EPA has made available in the repository, the EPA may, upon request, include

the document in the repository or make the document available for review at an alternate location.

This applies to documents such as verified sampling data, chain of custody forms, guidance and

policy documents, as well as voluminous site-specific reports. It does not apply to documents in

EPA’s confidential file. (Copies of guidance documents also can be obtained by calling the

RCRA/Superfund/Title 3 Hotline at (800) 424-9346.) 

These requests should be addressed to:

Remedial Project Manager

U.S. EPA Region 6

1445 Ross Avenue

Dallas, Texas 75202-2733

(214) 665-8143

The EPA response selection guidance compendium index has not been updated since

March 22, 1991 (see CERCLA Administrative Records: First Update of the Compendium of

Documents Used for Selecting CERCLA Response Actions [March 22, 1991]); accordingly, it is not

included here. Moreover, based on resource considerations, the Region 6 Superfund Division

Director has decided not to maintain a Region 6 compendium of response selection guidance.

Instead, consistent with 40 CFR Section 300.805(a)(2) and 300.810(a)(2) and OSWER Directive No.

9833.3A-1 (page 37), the AR File Index includes listings of all guidance documents which may form

a basis for the selection of the response action in question.

The documents included in the AR File index are arranged predominantly in chronological

order. The AR File index helps locate and retrieve documents in the file. It also provides an

overview of the response action history. The index includes the following information for each

document:

• Doc ID- The document identifier number.

• Date - The date the document was published and/or released. “01/01/2525" means no

date was recorded.

• Pages - Total number of printed pages in the document, including attachments.

• Title - Descriptive heading of the document.

• Document Type - General identification, (e.g. correspondence, Remedial Investigation

Report, Record of Decision.)

• Author - Name of originator, and the name of the organization that the author is

affiliated with. If either the originator name or the organization name is not identified,

then the field is captured with the letters “N/A”.

• Addressee- Name and affiliation of the addressee. If either the originator name or the

organization name is not identified, then the field is captured with the letters “N/A”.
