Chapter II II-16 JP 3-28 Emergency Preparedness Liaison Officer (EPLO) Programs. The EPLOs are aligned with the 10 DCEs and their associated FEMA regions. (1) EPLOs are senior RC officers who are administered by, and report to, program managers within their respective Services responsible for organizing, training, and equipping personnel for a DSCA response. (2) EPLOs are trained in emergency management and DSCA operations. EPLOs advise civil authorities on military resources and capabilities and facilitate coordination between civil authorities and DOD during state or federal exercises or DSCA operations. (3) EPLOs are activated and employed by their Services at the request of the supported CCDR to support the DCO or as coordinated with the CCDR to facilitate Military Department response. EPLOs, provided in support to the DCO, will normally be under tactical control of the DCO. When in support of the Military Departments, EPLOs will be under OPCON to the appropriate military commander. (4) Regional EPLOs normally support the DCO but can be located pre-event at the regional response coordination center and then moved forward to the JFO with the DCO. (5) State EPLOs are aligned with the appropriate DCO but are oriented toward supporting the state emergency response team and the NG JFHQ-state. (6) Joint Regional Medical Planning Officer. Joint regional medical planning officers provide direct medical planning and operations support to DCOs and liaise with ESF#8 (Public Health and Medical Services) authorities within designated operational areas when directed. They advise the joint force surgeons on the synchronization and integration of DOD medical assets with federal, state, and local medical assets. For more information on EPLO, refer to DODI 3025.23, Domestic Defense Liaison with Civil Authorities. 10. Planning Considerations for Defense Support of Civil Authorities To expedite planning and operational response during crisis situations, the CJCS publishes a DSCA EXORD and a CBRN response EXORD to allow prompt force deployment in support of domestic incidents. DOD planners work hand-in-hand with NG and civilian planners to develop tailored regional civil-military plans for DSCA. These plans inform local, territorial, tribal, state, and national planning efforts. For further information, see CJCS DSCA EXORD; CJCS CBRN Response EXORD; USNORTHCOM CONPLAN 3500, Defense Support of Civil Authorities (DSCA); USNORTHCOM CONPLAN 3502, Civil Disturbance Operations; USINDOPACOM CONPLAN 5001, Defense Support of Civil Authorities (DSCA); JP 3-41, Chemical, Biological, Radiological, and Nuclear Response; and the NGB All Hazards Support Plan.
