The main purpose of this legislation is to ensure that the Federal Emergency Management Agency (FEMA) can effectively respond to disasters by appointing an Acting Regional Administrator whenever a Regional Administrator position has been vacant for at least 90 days. This aims to prevent delays in disaster relief efforts and improve the agency's overall efficiency in managing federal assistance during emergencies. Key provisions of the legislation require the FEMA Administrator to establish a process for appointing an Acting Regional Administrator in cases of prolonged vacancies.
