Superfund Site Administrative Records

An administrative record file is a 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. This does not mean that only documents which support a response decision are placed in the administrative record. Relevant documents that were relied upon in selecting the response action, as well as relevant documents that were considered but ultimately rejected, are included. The administrative record also acts as a vehicle for public participation in selecting a response action.

Administrative record files may be added to as relevant documents are generated or received by the EPA. The administrative record is not complete until it contains a decision document (e.g., Record of Decision (ROD) or Action Memorandum). At a given Superfund site there may be several removal actions, and/or remedial actions known as operable units (e.g., Soils Operable Unit, Groundwater Operable Unit.) For every removal action or operable unit, a separate administrative record is compiled.

How Are Administrative Records Organized in Region 9?

In Region 9, administrative records are organized chronologically by document date, with undated documents listed at the beginning. The index serves as an overview of the history of the response action at the site and plays a key role in document location and retrieval.

For remedial sites, the administrative record file is typically compiled and first made available to the public during the remedial investigation/feasibility study (RI/FS) activity phase. The file is added to as relevant documents are generated or received by the EPA. The file is not complete until the decision document (e.g., Record of Decision) is added. Occasionally, a ROD Amendment or Explanation of Significant Differences (ESD) is added following the Record of Decision.
