Dual Site Groundwater Operable Unit (part 3)

Administrative Record Index

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

On March 30, 1999, after considering and responding to public comments, EPA selected the cleanup action for the Dual Site Groundwater Operable Unit at the Montrose Chemical and Del Amo Superfund Sites, in Los Angeles, California. This cleanup applies to groundwater at both sites.
For the Montrose Chemical and Del Amo Superfund sites, EPA is housing a copy of its administrative record at this library. The documents contained in this AR were considered by the EPA in the process of selecting this groundwater cleanup action. A copy of the AR is also maintained at the EPA Regional Office in San Francisco.

The Dual Site Groundwater Operable Unit AR is entirely on microfilm. These microfilmed documents are arranged in ascending chronological order with undated documents at the beginning of the sequence. Each document has been assigned a unique identification number.

This administrative record includes by reference the documents in the Del Amo Superfund Site Waste Pits Operable Unit AR and the Montrose Chemical Corporation Superfund Site Removal Action No. 2 AR (Sediments in Sanitary Sewers). These administrative records are also available for viewing at this repository.

The list of U.S. Environmental Protection Agency guidance documents that were considered or relied upon in the selection of the remedial action is document AR #5014 in this AR file. Copies of the guidance documents are contained in the Compendium of CERCLA Response Selection
Guidance Documents and are available for review in the Region 9 Superfund Records Center.

As an additional service to the public, EPA has also placed paper (hard) copies of 6 critical reports related to this remedial action selection process in this library. While these reports appear on the microfilm as well, they are easier to use and review in paper copy. If you are interested in the paper copies of these reports, please ask the librarian where they can be reviewed.

The reports which are present in this library in both paper copy and microfilm copy are:

1. Final Remedial Investigation Report for the Montrose Site; Los Angeles, California; May 18, 1998; originally prepared by Montrose Chemical Corporation of California and Revised by U.S. Environmental Protection Agency, Region IX. 2 volumes.


2. Final Groundwater Remedial Investigation Report; Del Amo Study Area; May 15, 1998; prepared by Dames & Moore for the Shell Oil Company and The Dow Chemical Company. 3 volumes.

3. Final Joint Groundwater Feasibility Study for the Montrose and Del Amo Sites; Los Angeles, California; May 19, 1998; prepared by CH2M Hill for the U.S. Environmental Protection Agency, Region IX. 1 volume.

4. Joint Groundwater Risk Assessment; Montrose and Del Amo Sites; Los Angeles County, California; February 1998; prepared by McLaren Hart for the Montrose Chemical Corporation, and Dames & Moore for the Shell Oil Company and The Dow Chemical Company. 1 volume.

5. Supplement to the Joint Groundwater Risk Assessment for the Montrose and Del Amo Sites; Los Angeles, California; May 18, 1998; prepared by CH2M Hill for the U.S. Environmental Protection Agency, Region IX. 1 volume.

6. Record of Decision for Dual Site Groundwater Operable Unit; Montrose Chemical and Del Amo Superfund Sites; March 30, 1999; U.S. EPA Region IX. 2 volumes.

The Record of Decision (item 6) can also be viewed or downloaded from the World Wide Web at http://www.epa.gov/region09/waste.
