Fire Suppression and Response Funding Assurance Act

This bill amends the Robert T. Stafford Disaster Relief Act to require the federal government to cover at least 75% of eligible costs for fire suppression and response activities funded under Section 420. It directly affects state and local governments receiving federal disaster relief by guaranteeing a higher minimum federal cost share and allowing funds to cover predeployment of fire resources. Key provisions include setting the 75% federal cost share floor (previously lower or variable), explicitly permitting predeployment expenses, and mandating a rulemaking within 3 years to establish criteria for potentially increasing the federal share further. The changes apply only to funds appropriated after the bill's enactment.
