This instruction implements Air Force Policy Directive (AFPD) 90-20, Mission Sustainment. It
provides guidelines for managing and reporting hazards that pose both current and future risks to
Air Force mission operations. It applies to all Regular Air Force and Air Force Reserve
installations located in the United States, its territories, and possessions, including government-
owned, contractor-operated facilities. It also applies to the National Guard Bureau, which will
develop supplemental guidance for Air National Guard units. This instruction also applies to Air
Force installations outside the United States, its territories, and possessions, but mission
sustainment practices at these locations will be consistent with applicable international
agreements, including status of forces agreements and other government-to-government
agreements, Combatant Command policy, and Lead Environmental Component directives. It does
not apply to contingency locations. It may be supplemented at any level, but all supplements must
be routed to the Office of Primary Responsibility (OPR) for coordination prior to certification and
approval. Refer recommended changes and questions about this publication to the OPR using Air
Force Form 847, Recommendation for Change of Publication; route Air Force Form 847s from
the field through the appropriate functional chain of command. The authorities to waive wing/unit
level requirements in this publication are identified with a Tier (“T-0, T-1, T-2, T-3”) number
following the compliance statement. See Air Force Instruction (AFI) 33-360, Publications and
Forms Management, for a description of the authorities associated with the Tier numbers. Submit
requests for waivers through the chain of command to the appropriate Tier waiver approval
authority, or alternately, to the requestor’s commander for non-tiered compliance items. Ensure
that all records are maintained in accordance with Air Force Manual (AFMAN) 33-363,
