This bill would require the Federal Emergency Management Agency to reimburse public employee retirement systems for the costs of disability retirements and death benefits for workers who were injured or died while participating in rescue, recovery, or cleanup operations at the World Trade Center on September 11, 2001. The reimbursements would cover any retirement system that had members involved in those 9/11 response operations. The bill authorizes $3.4 billion in funding for fiscal year 2024 to cover these reimbursements, and the money can only be used by the retirement systems themselves, not by other entities. This legislation aims to ensure that public employee pension systems are compensated for the long-term costs they have borne from providing benefits to workers disabled or killed in the 9/11 attacks.
