• Camp Fannin is a Formerly Used Defense Site (FUDS).
• Congress established the FUDS Program in 1986.
• US Army Corps of Engineers manages FUDS Program for Department of Defense (DoD).
• The Corps’ Fort Worth District manages FUDS projects including the former Camp Fannin in Smith County.

FUDS Program Development
FUDS Program FUDS Program DevelopmentDevelopment
• Formerly Used Defense SitesFUDS are properties that were formerly owned, leased, possessed by, or otherwise under the operational control of the DoD or military prior to 1986.
• Locate sites through Real Estate research– Establish use through historical search, including
archives searches and aerial photo analysis– Visual site inspections
• Prioritize sites and execute project

Our focus is minimizing the safety hazards from MEC remaining at this FUDS site.
MEC and UXO: – MEC consists of munitions and explosives,
including fired and/or discarded items, explosive filler, etc.
– UXO is defined as unexploded ordnance– UXO is a subset of MEC

Next Step is InvestigationNext Step is InvestigationNext Step is Investigation
• Engineering Evaluation/Cost Analysis (EE/CA)
– Started in 2003, however…
– During the timeframe in which the previous study began, the DoD, and the Corps began transitioning to more comprehensive studies of MMRP FUDS sites like Camp Fannin. The EE/CA was pulled back in favor of a more comprehensive RI/FS.
– Rather than focusing only on evaluation of explosive hazards, as the EE/CA would have done, the RI/FS will include an evaluation of the potential for munitions constituents (MC) contamination.

Purpose of Proposed RI/FS Investigation
Purpose of Proposed RI/FS Purpose of Proposed RI/FS InvestigationInvestigation
“To characterize the nature and threat posed by the hazardous substance and/or military munitions, and gather data necessary to assess the extent to which the release poses a threat to human health, safety, or the environment.
“In addition, data should be gathered to support the analysis and design of potential response actions by assessing the following factors [40 CFR 300.430(d)(2)]:
December 09 2008
32
• Physical characteristics of the property;• Characteristics/classification of soil, surface water, and
groundwater;• Characteristics of the military munitions (e.g., quantities,
concentration, toxicity, persistence, mobility, depth, nature and extent, etc.);
• The extent to which the source can be characterized; • Actual and potential exposure pathways through
environmental media;• Actual and potential exposure routes (e.g., inhalation and
ingestion); and• Other factors such as sensitive populations that pertain to the
characterization of the site or support the analysis of potential remedial action alternatives.
These data will be used to identify relevant and applicable regulations, remediation goals, objectives and to screen various remedial alternatives.

• Prior to Fieldwork an executed Right-of-Entry agreement is required from each affected landowner.
• ZAPATA will assist Corps’ Fort Worth District in obtaining Rights-of-Entry by:– Notifying landowners via correspondence package to include
USACE ROE Letter/Form, Property Description, and a USACE-approved fact sheet.
– Going Door-to-Door for personal meetings to assist in acquiring ROEs
– Updating the Mailing List with Landowner Information– Conducting events to facilitate public understanding of
project.

• ROEs will be executed by Corps’ Fort Worth District Real Estate Division.
• ROEs can be revoked at any time by the landowner.
• Letters with ROE requests will be going out to landowners in the next month.
• ZAPATA must collect sufficient ROEs to warrant a notice to proceed with fieldwork.

Ground Reconnaissance will be conducted using metal detectors in the buffer surrounding impact area.
Ground Reconnaissance will determine whether the actual Area of Concern is greater than the presently delineated area defined by archival maps.
Archival Range Information, indicates eleven overlapping ranges in MRS - 1.
Overlapping fans form the red outline; the interior of which is referred to as the Impact Area.

access for surveying and data collection. – Only brush less than three inches in diameter will
be cut, in direct coordination with the District.– Combination of mechanical and manual methods
(chain saws, weed whackers, and a tracked ASV PT-100). A UXO Tech II will provide safety escort during brush removal activities.

– Flag the location of each reacquired anomaly shown on the dig sheet.
– Refine the target anomaly with a metal detector.– If a response is noted within a 1.5 meter radius of
this site, the object is dug.
