ofreference (b). Based on the information provided, approval is granted for removal and
treatment ofmaterial potentially presenting an explosive hazard (MPPEH) and munitions and
explosives ofconcern (MEC) at Former Fort Ord, Monterey County, CA. This approval is based
on the following:
a. The efforts addressed in this ESS involve manual unintentional detonation
operations and intentional detonations supporting munitions response actions within Munitions
Response Area (MRA) Unit 7 and MRA Unit 10.
b. The munition with the greatest fragmentation distance (MGFD) for the MRA
Unit 7 is the 75mm M48 Projectile; the minimum separation distance (MSD) for teams for
manual unintentional detonation operations is 75 feet (ft) based on K40 ofthe 4.5-inch Mk 3
Barrage Rocket; the MSD for nonessential personnel from manual unintentional detonation
operations is 316 ft based on the hazardous fragment distance (HFD) ofthe 4.5-inch Mk 3
Barrage Rocket; and the MSD for all personnel from intentional detonations is 1,794 ft based on
the maximum fragment distance (MFD) ofthe MGFD.
c. The MGFD for the MRA Unit lOis the 75mm HE Mk I Projectile; the MSD
for teams for manual unintentional detonation operations is 47 ft based on K40 ofthe MGFD; the
MSD for nonessential personnel from manual unintentional detonation operations is 239 ft based

on the HFD of the MGFD; and the MSD for all personnel from intentional detonations is 1,873 ft
based on the MFD of the MGFD.

g. Chemical agent identification set (CAIS) kits (i.e., K951/2, K953/4 and K955)
that contain dilute chemical agents or industrial chemicals will be treated as a hazardous waste.
Ifother CAIS, a munition with an unknown fill, or chemical warfare material is encountered all
work will cease pending Army assessment ofthe need to submit a Chemical Safety Submission.
h. Prior to initiation and through completion ofon-site explosives operations, all
nonessential personnel will be evacuated and prevented from entering any area/facility
encumbered by the MSD required for the operation being conducted, or explosives operations
will be suspended ifnonessential personnel enter the MSD.
i. MPPEH will be inspected and classified as material documented as safe prior
to release to the public.
Ifchanges occur during or after completion ofthis effort that could increase explosive
hazards to site workers or the public due to the presence 0 I itary munitions at the site, an
amendment to this ESS must be submitted to DDESB for. revi and approva1.
