"The NRCC is the national-level interagency coordination center at FEMA Headquarters. The NRCC issues mission assignments at the national level as needed. The NRCC works closely with the Regional Response Coordination Center(s) (RRCC) or the Joint Field Office(s) (JFO) to ensure that mission assignments are not duplicated. The NRCC is responsible for adjudicating conflicts with requests for national resources". (FEMA, Mission Assignment SOPs Draft, 2007, p. 4; also 56).
