Final Second Five-Year Review Report Fort Ord Superfund Site ...

• Preparation of a burn plan outlining the objectives of the burn; the burn area; the range of
environmental conditions under which the burn will be conducted; the manpower and equipment
resources required to ignite, manage, and contain the fire; a smoke management plan; and
establishment of communication procedures for the fire crew and to the public and other affected
agencies.
• Site preparation, including removal of debris; establishment and maintenance of primary, secondary,
and tertiary containment lines, staging areas, and escape routes; and protection of existing structures
by removing nearby vegetation and applying fire suppressant foam or demolishing and removing the
structures.
• Conducting the burn within the window of environmental conditions established in the burn plan.
• Conducting the burn in a manner to ensure the fire is fully contained and does not escape the
perimeter of the burn area.
• Offering voluntary temporary relocation for any Monterey County resident who wishes to relocate
during a prescribed burn.
• Conducting air monitoring during the prescribed burns; data will be used to further evaluate the
effectiveness of prescribed burning as a vegetation clearance alternative.
MEC Remedial Action via Surface and Subsurface MEC Removal
Surface and Subsurface MEC Removal will consist of identification of MEC (conduct a visual search and
operate MEC detection equipment), and remediation of any MEC found/detected on the ground surface of
the site and in the subsurface to depths determined in the site-specific work plan. Subsurface MEC
removal depths will be determined based on: (1) the type of MEC, (2) the typical depth at which the
MEC type is found, (3) planned reuse of specific areas within the IA site, and (4) the capabilities of the
geophysical detection equipment selected as best suited for site conditions by the MEC site geophysicist.
MEC Detonation via Detonation with Engineering Controls
MEC Detonation with Engineering Controls will consist of applying additional detonating charges to
single or consolidated MEC items, and applying engineering controls (covering the MEC with tamped
dirt, sandbags, contained water, or other materials) prior to detonation to reduce the blast and any
associated fragmentation, emissions, or noise.
15.2.2 Remedy Implementation
Ranges 43-48
Prescribed burning was conducted in October 2003. Surface and subsurface MEC removal were
conducted on the 499.5-acre MRS-Ranges 43–48 site from November 2003 to December 2005. The
surface removal for MRS-Ranges 43-48 has completed over the entire site, and the subsurface removal
has been conducted to the maximum capability of the technologies and instruments used in all portions of
the site that could be completed within the environmental, funding and time constraints of the contract.
Based on the results of this IA, the imminent threat posed to the public by the presence of MEC on this
site has been significantly mitigated.
Approximately 227.2 acres of the removal area have been designated SCA or non-completed areas. The
immediate threat posed to the public by these SCAs has been significantly mitigated because a surface
removal of MEC was completed in these areas (Parsons, 2007).
The remaining explosive risks at Ranges 43-48 and the IA work completed will be evaluated under the
MR RI/FS program.
