ADMINISTRATIVE RECORD CUMULATIVE INDEX

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION IX FACT SHEET FACT SHEET Administrative Records in Local Repositories The "administrative record" is the collection of documents which form the basis for an agency's decision, in this case the selection of a response action at a Superfund site. Under Section 113(k) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA), EPA is required to establish an administrative record for every Superfund response action and to make a copy of the administrative record available at or near the site. . ' . The administrative record must be reasonably available for public review during normal business hours. It should be treated as a non-circulating reference document, in order to allow the public greater access to the record and also to minimize the risk of loss or damage. Individuals may copy any documents contained in the administrative record, according to the copying procedures at the local repository. The administrative record will be maintained at the local repository until further notice. Periodically EPA may send supplements and indexes directly to the local repository. These supplements must be placed with the initial administrative record. Questions regarding the maintenance of the administrative record should be directed to: Administrative Record Coodinator Superfund Records Center U.S. EPA (H-6-1) 75 Hawthorne Street San Francisco, CA 94105 . . (415) 744-2165

EPA welcomes comments at any time on documents contained in the administrative record. Please send comments on the Iron Mountain Mine Administrative Record to: Rick Sugarek or: Fraser Felter Remedial Project Manager Community Relations Coordinator U.S. EPA (H-6-2) U.S. EPA (H-l-1) 75 Hawthorne Street 75 Hawthorne Street San Francisco, CA 94105 San Francisco, CA 94105 (415) 744-2226 (415) 744-2181 or 1-800-231-3075 EPA may hold formal public comment periods at certain stages of the response process. The public is urged to use these formal \) review periods to submit their comments. INTRODUCTION INTRODUCTION

IRON MOUNTAIN MINE SUPERFDND SITE

BOULDER CREEK OPERABLE UNIT Redding, California Administrative Record and Index

The administrative record file for the Iron Mountain Mine Superfund Site Boulder Creek Operable Unit, Redding, California, contains documents ranging in date from June 1901 to May 1992. Two indexes are provided. The first index presents the documents in ascending chronological order. Undated documents are placed at the beginning of each sequence. The second index presents the documents in exactly the order in which they appear on the rolls of film. This second index is not in strict chronological order. Each document in both indices is assigned a unique number from 1 to 2,446. Records beginning with MWA" in the subject description were indexed by CH2M Hill. Oversize documents, such as maps, are on a separate roll of wider (35 mm) film. A list of abbreviations and acronyms with their full names is provided in this binder. After the numbering and microfilming process had been completed, EPA determined that approximately 126 documents, not part of the administrative record, had been inappropriately included. These documents are not included in the administrative record and account for occasional gaps in the number sequence of the administrative record index. Having been removed from the index, they still remain represented on microfilm with confidential targets. These targets should be disregarded.

DOCUMENTS HOUSED IN RECORDS CENTER Approximately 50 documents in this administrative record consist of sampling and computer modeling data that have been determined too voluminous to be physically included in the body of documents at the repositories. Although EPA guidance indicates it is not necessary to include such documents in the information repositories, these documents have been made available for public review at the Region 9 Superfund Records Center in San Francisco. In addition, there are a number of documents or parts of documents which do not lend themselves to microfilm reproduction. Most of these documents are color photographs which copy poorly on microfilm. These documents are also available for public review at the Records Center in San Francisco. If you wish to review any of these documents not available in the repositories, please contact Region 9 Superfund Records Center, H-6-l, 75 Hawthorne Street, San Francisco, CA 94105; Phone: (415) 744-2166. ITEMS HOUSED AT CH2M HILL, REDDING, CALIFORNIA Certain oversize mine maps, photographs, and analytical sampling data produced by CH2M Hill, are listed in the administrative record, in AR 74 and AR 2418. The items themselves are available for public review at CH2M Hill, 2525 Air Park Drive, Redding, CA 96001; Phone: (916) 243-5886.
