Supporting a Comprehensive All Hazards Response II-13 b. Title 32, USC, Section 317, states DSC-led JTFs should be the usual and customary C2 arrangement established in response to an emergency or major disaster within the US when both federal and state military forces are supporting the response. c. Requests for DSCA should be written and include a commitment to reimburse DOD IAW the Stafford Act; Title 31, USC, Section 1535 (also known as the Economy Act of 1932); or other authorities, except requests for support for immediate response and mutual or automatic aid, IAW DODD 3025.18, Defense Support of Civil Authorities (DSCA). Unless approval authority is otherwise delegated by SecDef, all DSCA requests shall be submitted to the office of the Executive Secretary of DOD. d. Civil authorities shall be informed that verbal requests for DOD assistance during emergency circumstances must be followed by a formal written RFA, which includes intent to reimburse DOD, at the earliest opportunity. Support may be provided on a non- reimbursable basis only if required by law or if both authorized by law and approved by the appropriate DOD official. e. Civil authority requests for DOD assistance are evaluated for: (1) Legality (compliance with laws). (2) Lethality (potential use of lethal force by or against DOD forces). (3) Risk (safety of DOD forces). (4) Cost (including the source of funding and the effect on the DOD budget). (5) Appropriateness (whether providing the requested support is in the interest and within the capability of DOD). (6) Readiness (impact on DOD’s ability to perform its primary mission). f. DSCA plans will be compatible with the NRF, NIMS, and DOD issuances. DSCA planning will consider C2 options that emphasize unity of effort. g. With limited exceptions (e.g., local requests for immediate and emergency response), initial RFAs will be directed to OSD, Executive Secretariat. SecDef-approved RFAs are assigned to the appropriate CCDR. The supported CCDR determines the appropriate level of C2 for each response and usually directs a senior military officer to deploy to the incident site. The DCO serves as DOD’s single point of contact in the JFO. DSCA requests originated in the JFO will be coordinated and processed through the DCO with the exception of requests for United States Army Corps of Engineers (USACE) support or, in some circumstances, DOD forces in support of the Federal Bureau of Investigation (FBI) or the United States Secret Service (USSS).
