H.R. 9609 amends the Small Business Act to make it easier for disaster victims to apply for federal assistance from the Small Business Administration. The bill extends application deadlines by 60 days for major disasters and allows the SBA to accept late applications if applicants can show good cause for missing the original deadline. Additionally, the bill requires the SBA to make extra efforts to inform the public and congressional offices representing disaster-affected districts about these application deadlines and relief requirements. The changes aim to improve access to disaster relief by giving affected businesses and individuals more time and better information about available assistance programs. The bill does not specify new funding amounts or implementation dates beyond the provisions themselves.
