## 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. Section9613 (k)(1), requires the EPA to establish an AR upon which it shall base the selection of its remedialactions. 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 tomake the AR File available to the public at or near the site of the response action. Accordingly, the EPAhas 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 ARFile 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 ARFile were compiled in accordance with the EPA’s Final Guidance on Administrative Records for Selecting CERCLA Response Actions, Office of Solid Waste andEmergency Response (OSWER) Directive Number 9833.3A1 (December 3, 1990).

### 2 

## Documents listed as bibliographic sources forother documents in the AR File might not be listed separately in the index. Where a documentis listed in the index but not located among the documents which the EPA has made available inthe 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. (Copiesof guidance documents also can be obtained by calling the RCRA/Superfund/Title 3 Hotline at (800) 424-9346.)

These requests should be addressed to: Katrina Higgins-Coltrain 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 ResponseActions [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”.
