When the impact of a disaster is so severe  that neither the State nor local government can adequately respond, either by  direct performance or by contract, the State may request that certain  emergency work be performed directly by a Federal Agency. This is called Direct Federal Assistance. Under the  provisions of 44 CFR §206.208, FEMA, through “Mission Assignments,” may use  appropriate Federal agencies to perform work or to contract for it to be  performed.
   The work to be performed must be eligible under  the Stafford Act and Federal regulations, and is limited to:
   †  Debris  removal
   †  Emergency  protective measures
   †  Emergency  communications
   †  Emergency public  transportation
   There may be a limited period of 100% Federal  funding when conditions warrant. Otherwise, the assistance is subject to the  cost-sharing provisions applicable to the disaster. The State must reimburse  FEMA for the appropriate non-Federal share of the cost of the work, including  any administrative costs of the performing Federal agency.
