Draft Focused Site Inspection Phase II Work Plan -Naval Weapons Station
City Council Staff Report
October 11, 1999
Overview of Proposed Project:
DON is requesting comments on the Draft FSI II Work Plan by October 29, 1999. Staff has
prepared a "Draft Comment Letter" for consideration by the EQCB and the City Council, provided
as Attachment 1. The EQCB considered this matter on September 29, 1999, and determined to
froward the comment letter to the City Council without any modifications.
Staff provided the Report and pages A-12 through A-44 of Appendix A — Field Sampling Plan for
the information of the EQCB (See Attachment 2). These pages and the remainder of Appendix A,
and Appendices B through G, comprise the majority of the document (315 pages) and are available
for review at the Mary Wilson Library, 707 Electric Avenue, and at the Department of
Development Services, City Hall, 211 Eighth Street.
Overview of Draft Focused Site Inspection Phase II Work Plan:
The objective of the subject report is to supplement data obtained during previous site investigations
at the subject sites to:
o carry out the recommendations as a result of previous Installation Restoration Program
(IRP) investigations;
o screen for ecological and human health risks;
o fill data gaps from previous investigations;
o supplement information presented in past site inspections; and
o to decide whether cleanup or no further action is warranted at specific sites.
This Draft FSI Phase II Work Plan includes a brief description and historical overview of each site
and a summary of the previous investigations conducted, including definition of the remaining data
gaps to be addressed; and a description of the additional information gathering steps to be taken.
The overall purpose of the FSI Phase II effort is to close existing data gaps by:
o Better delineating the lateral and vertical extent of chemicals of potential concern (COPC) in
soils, sediments, and groundwater(as necessary).
o Evaluating COPC concentrations in soil sediment and groundwater (as necessary) to assess
the potential threat to human health and the environment through screening risk
assessments.
o Evaluating the Installation Restoration Program (IRP) locations for potential
No Further Action (NFA), removal actions, or further evaluations (with an emphasis on the
former two types of decisions).

understandable, with Section 2, "Locations Background" being very helpful. Table 3-1, "Revised
DQO Summary, Focused Site Inspection Phase II is extremely helpful in obtaining a quick
overview of each site, and the 7-step process to be undertaken to fill the specific data gaps
remaining from previous investigations. In addition, the discussion and presentation of information

City Council Staff Report
October 11, 1999
Overall, staff has no concerns regarding the amount or locations of the proposed additional
investigations for each site. The document does indicate that the investigations at Site 73, the
Water Tower Area, is within archaeological site CA-ORA-322/1,118, which is considered to be
eligible for the National Register of Historic Sites, and therefore an fieldwork will require the
presence of a qualified archaeological monitor (page 2-14). It is recommended that the comment
letter request the presence of a qualified "Native American monitor" also.
Restoration Advisory Board (RAB) Information Materials:
Provided as Attachment 3 is a copy of the presentation materials submitted to the RAB on August
11, 1999. This information packet provides an overview of the objectives of the FSI Phase II
Work Plan, an overview of the sampling strategies by site, and a summary. These materials are
also not provided with the City Council Staff Report, and are available for review by the City
Council or the public at the Department of Development Services.
FISCAL IMPACT
None, all activities associated with this project are the responsibility of the Department of Navy,

Dear Ms. Tamashiro:
SUBJECT: CITY OF SEAL BEACH COMMENTS RE: "DRAFT FOCUSED
SITE INSPECTION PHASE II WORK PLAN, NAVAL WEAPONS
STATION"
The City of Seal Beach has reviewed the above referenced document and is in general agreement
with the proposed work plan. The work plan will better define the appropriate actions to take to
eliminate existing potential adverse impacts to the residents of the City of Seal Beach and to
employees of the Weapons Support Facility at the 14 sites to be investigated in the Phase II work
plan. The overall structure of the document is well organized, with Section 2, "Locations
Background" being particularly helpful to the general reader. In addition, Table 3, "Revised DQO
Summary - Focused Site Inspection Phase II" is helpful in presenting at a quick overview of the
data quality objectives to be utilized in order to arrive at a final site decisions for the targeted
locations.
The City also supports the following proposals contained within the FSI Phase II Work Plan
document:
o The proposed "Study Boundaries" set forth in Step 4, Table 3-1.
o The proposed "Decision Rules" set forth in Step 5, Table 3-1.
o The proposed "Optimize the Sampling Design" set forth in Step 7, Table 3-1".

It would be helpful in the "Final" document to include the site specific information regarding the
following areas in a Table within the main document, perhaps as Table 3-2, that is now included
within Appendix A, pages A-12 through A-44:
o Sampling Objective
o Proposed Activities
o Performance Methodology
a Data Use, and
a Potential Receptors of Concern
Providing this information in a Table within the main document would allow the general reader to
obtain a very good summary of the sampling program proposed for each site, the use of the
collected data, and the receptor of concern.
In regards to Site 73, Water Tower Area, the City supports the required presence of a "qualified
archaeological monitor" during fieldwork at this site. However, given the potential significance of
the archaeological site, which overlaps the Water Tower site, it is requested that a qualified Native
American monitor also be present during all fieldwork activities at this site.
In reviewing the discussion regarding SWMU 24 - Stationary Demilitarization Furnace Facility,
and Section 4, References, the City is now aware of the decommissioning of this facility in 1998.
Please provide a copy of the June 1998 report by Brown and Caldwell, titled "Decommissioning
Plan of Action (DPOA)for Stationary Demilitarization Furnace at Weapons Support Facility, Seal
Beach, California" and the 12 January 1999 report of Foster and Wheeler titled "Draft Project
Closeout Report:Decommissioning of Stationary Demilitarization Furnace Facility, Naval Weapons
Station, Seal Beach, California" for our information and files. Please provide these documents to
Mr. Lee Whittenberg, Director of Development Services, 211 Eighth Street, Seal Beach, CA
90740.
Thank you for allowing us to comment on the draft "Focused Site Inspection Phase II Work Plan".
If you have any questions or require further information, please contact Mr. Lee Whittenberg,
Director of Development Services Department, (562) 431-2527 at your earliest convenience. He
will be able to respond to any additional questions which you may have regarding this matter.
Sincerely,
Paul Yost William G. Hurley, Vice-Chairperson
