Since Hurricane Katrina struck, the Federal Emergency Management Agency has paid 669 million dollars nationwide to families affected by the storm.
A FEMA spokesman says the agency has registered 573,262 households nationwide for benefits.
A memo released by Senator John Cornyn of Texas details how local and state governments could be reimbursed for assisting evacuees.
FEMA will reimburse governments for lodging, housing, transportation and labor costs. Many expenses related to education and health care will also be reimbursed, but not the costs of hiring extra teachers or buying additional textbooks.
The memo also says churches and other faith-based organizations will have to work through local governments for reimbursement, while private families are not eligible to get repaid.
