Appendix C – Group 10 Debris Survey

C.1 Introduction
This appendix presents the results of the Group 10 debris survey activities performed in
2008 at the Santa Susana Field Laboratory (SSFL) in Ventura County, California. The project
was performed to support the Resource Conservation and Recovery Act (RCRA) Facility
Investigation (RFI) Program at SSFL.
The debris survey included the entire SSFL and was performed as a joint effort by
CH2M HILL and MWH. Each consultant performed the survey activities for select RFI
groups, as summarized below:

•    CH2M HILL: Groups 1B, 2, 3, 4, 5, 7, 9, and 10
•    MWH: Groups 1A, 6, and 8
Activities associated with the debris survey and subsequent sampling was performed in
accordance with the Standard Operating Procedure for Onsite Debris Survey and Sampling
Methodology (CH2M HILL and MWH, 2008).
The information presented in this appendix is limited to Group 10 and only includes debris
areas that were identified during the 2008 debris survey activities. Debris survey
information for the other groups will be provided in their respective group reports.


C.2 Purpose and Scope
The purpose of the debris survey was to conduct systematic visual inspections of the SSFL
for surficial evidence of solid waste disposal (referred to herein as debris areas) and
sampling for chemical analytes at the debris areas. Types of solid wastes that were targeted
as part of this survey included, but were not limited to, the following:

•    Containers, including cans, bottles, drums, and tanks.

•    Soil piles with intermixed debris, including concrete, asphalt, metal or wood debris.

•    Hummocky terrain areas that may indicate historic dumping of soil. Note that some
     areas at SSFL, particularly in the undeveloped portions of the facility, have evidence of
     soil mounding that appears to be associated with firebreak grading performed during
     recent wildfire events (e.g., the 2005 Topanga Fire). These areas would not typically be
     identified as debris areas.

•    Building demolition debris, including pieces of broken concrete or asphalt pavement.
     Note that small, scattered pieces of concrete and/or asphalt unassociated with a debris
     or soil pile are not typically identified as debris areas.

•    Wood debris and pipe segments, including metal, transite, clay, and plastic.



SCO/APPENDIX_C_TEXT_DTSC-V01.DOC                                                                 1
•    Skeet target (clay pigeon) fragments.

•    Miscellaneous other non-household-type debris.
This debris survey was not intended to address the following types of features:

•    Household-type debris (e.g., food containers)

•    Features consisting solely of nonhazardous items such as concrete, asphalt, and rebar
     and other inert metal piles(i.e., items are not intermixed with soil).

•    Areas with materials of known origin and quality (i.e., no hazardous substances
     present), or material stockpile areas that are being actively managed.

•    Areas with buried debris potentially present, but with no indications on the ground
     surface based on visual inspection.
Debris identified as potentially hazardous or as being a potential source of contamination
will be considered for further evaluation in the RFI sampling programs. Specific
recommendations for further evaluation, including sampling as appropriate, are discussed
in Section C.4.
Note that household-type debris (such as food containers and other nonhazardous waste-
related items) was not targeted in the debris survey. As a general site-wide housekeeping
effort, however, the debris survey crews collected small volumes of household-type waste
where encountered, which was subsequently disposed of offsite with the regular municipal
wastes generated at SSFL.


C.3 Methodology
The debris survey was conducted as a pedestrian survey inspection of the visible ground
surface. Prior to conducting fieldwork, the survey crews reviewed information relevant to
the survey task (such as previous SSFL debris area survey reports and other relevant
historical documents, and aerial photographs). The field survey teams consisted of two
individuals: one consultant staff and one SSFL facility maintenance staff (subcontracted by
Boeing).
The survey crews followed predetermined transects approximately 50 feet apart and
visually scanned the ground surface for evidence of debris. Closer transect spacing was
used, as appropriate, based on ground conditions encountered. For example, closer
attention was given to densely vegetated areas and drainages to achieve thorough visual
inspection. Survey teams utilized global positioning system (GPS) equipment to accurately
navigate within the survey area and record the location of debris areas.
Some areas of the SSFL could not be safely accessed due to the presence of steep terrain and
rock outcrops. These areas are illustrated in Figure C-1. During the survey, the inaccessible
areas were visually inspected (typically using binoculars) from the nearest vantage point
and documented accordingly.
The locations and descriptions of the debris sites were documented using hand-held GPS
units that were preprogrammed with data dictionaries to enable efficient data collection.
The units also allowed keyed entry of debris descriptions that were not included in the data

APPENDIX_C_TEXT_DTSC-V01.DOC                                                                    2
dictionary. Debris sites that were approximately 100 square feet or less in size (that is, less
than approximately 10 feet by 10 feet) were recorded with a single set of GPS coordinates.
Debris areas larger than 100 square feet were documented with the GPS unit by recording
the visible surface perimeter of the debris site. Figure C-2 presents the locations of the debris
areas identified.
Digital cameras were used to photograph each debris area identified. Attachment C-1
presents the photographs of the debris areas.


C.4 Sampling and Analysis
Based on field observations collected during the debris survey, each debris area was
evaluated to determine whether further evaluation as part of the RFI was warranted (that is,
sampling and analysis). Table C-1 presents sampling determinations for each debris area.
Soil samples were analyzed for the RFI screening suite: VOCs, polynuclear aromatic
hydrocarbons (PAHs), total petroleum hydrocarbons (TPH), and metals. The sampling
results for the debris areas are presented in Section 3 of the Group 10 RFI Report.
