Other Domestic Activities and Special Events IV-5 munitions or devices that create an actual or potential imminent threat to human health, including safety, or the environment, including property. (1) The following will require an immediate EOD response: military munitions, discarded military munitions, and UXO in the unauthorized possession or realm of public officials or lands, including items that were illegally removed from military installations; military munitions that land off range, munitions located on property formerly leased or owned by DOD (to include manufacturing areas, pads, pits, basins, ponds, streams, burial sites, and other locations incident to such operations); transportation accidents involving military munitions; or public possession of unauthorized military munitions potentially presenting an imminent and substantial endangerment to the safety and health of the population and the environment. Military munitions found in these conditions should be considered extremely hazardous and should not be disturbed or moved until technically qualified EOD personnel assess and determine the hazard. DOD officials, including local military commanders, provide EOD support for military munitions, discarded military munitions, and UXO that have DOD origins, or appear to have DOD origins, to include foreign ordnance (Title 42, USC, Sections 6905, 6906, 6912, 6921-6927, 6930, 6934, 6935, 6937-6939, and 6974). (2) Rendering safe and disposing of explosive hazards reported or discovered outside of DOD installations are primarily the responsibility of civil authorities. However, due to the potential lethality and danger to public safety, DOD EOD personnel may provide assistance upon request IAW DODD 3025.18, Defense Support of Civil Authorities (DSCA). (3) When responding to RFAs from civilian authorities under immediate response authorities, the closest, capable EOD unit, regardless of Service, will provide support. (4) Requests from civil authorities for non-immediate DOD EOD support are subject to approval by SecDef. Examples of non-immediate DOD EOD support include, but are not limited to, post-blast analysis, use of DOD material and equipment, and support of preplanned events. (5) DOD EOD forces providing support under immediate response authorities will comply with applicable local, state, and federal laws and regulations, including environmental laws and regulations. (6) The Bureau of Alcohol, Tobacco, Firearms, and Explosives is advised of the recovery and disposition of military munitions, as well as responses to nonmilitary munitions and explosives. The Services ensure reports are submitted within 72 hours to the Bureau of Alcohol, Tobacco, Firearms, and Explosives’ US Bomb Data Center. (7) Approvals from SecDef and Director, FBI; Federal Aviation Administration; Federal Communications Commission; and US Strategic Command are required for DOD EOD personnel to employ electronic countermeasures (ECM) in the US while conducting EOD support of civil authorities.
