The detonation exposed more UXO and that was also disposed of by detonation. The second detonation exposed additional UXO that the team did not have materials left to detonate with. Team recommended actions are: immediately post signs in possible UXO contaminated areas to increase awareness; full burn of vegetation in ordnance contaminated areas; after burn, conduct a full sweep of area; collect ordnance residue; separate hazardous and non-hazardous items; dispose of hazardous residue by detonation/thermite burn and; certify remaining items as scrap. |

Summary from SI.
The Demolition Area MRS is identified on an air photograph as two
distinct areas of craters. One group, in the northwest sector of the range has much larger craters than the ones in the southeast sector. These craters measure approximately 75 feet in diameter and close to 20 plus feet deep. The property around these larger craters is littered with MD, including an undetermined number of unexploded items. Items identified during previous field visits associated with the ASR include electric blasting caps, a MKII hand grenade, 20-mm and 37-mm projectiles, an armor piercing bomb, fragments and components of an M61 armor piercing high explosive bombs, debris from 20-lb or 23-lb fragmentation bombs, and unidentified bombs. The ASR Supplement assigned a RAC score of 3 to this MRS, with 5 indicating the least risk and 1 the highest risk.
The following list contains items reported, in an EOD incident report
as items recovered in the Demolition Area MRS:
• MK2 hand grenades
• Fragmentation of AP bomb, nomenclature unknown
• .30- and .50-caliber small arms ammunition
• Electric blasting caps
• Bomb tail fuze residue
• Fragmentation coils from 20 and 23 pound cluster bomb munitions
• Residue from M61 AP bomb
• M100 series bomb fuzes
• M51 series projectile fuze
• AN-M1 cluster munition racks
• 40mm Anti-Aircraft projectiles
• Base detonating 6” APHE Projectile fuze
• Cluster AN-M4 23 pound parachute retarded bombs
To assess the presence of MEC contamination at the Demolition Area MRS, the SVT performed QR within the range area (Figures 4.1b and 4.1c). Numerous craters were observed with non-identifiable metal fragments in the surrounding area .
There were numerous bomb parts throughout the area from 100-lb practice bombs and 100-lb GP bombs such as practice bomb fins and fragments. A 16-inch round fragment and a fragment from a large Navy round was observed. Flares with the parachutes still intact were found. In addition to MD, the Schonstedt detected surface and subsurface anomalies throughout the area. Areas of soil discoloration were also observed. Just north of the Demolition Area MRS, nine unfired 75-mm projectiles were found in the DMM Area AOC. |

DEC provided responses to comments for the Explanation of Significant Differences, Fort Glenn OB/OD Area (MRS-04), Formerly Used Defense Site, Umnak Island, Alaska, (dated April 2024) to the U.S. Army Corp of Engineers.
