Makes provisions permanent relating to disability due to disease or malfunction of the heart or coronary arteries

This bill makes permanent provisions regarding disability benefits for volunteer firefighters who suffer injuries due to heart disease or coronary artery malfunction. It amends existing laws to ensure these disability provisions remain in effect through June 30, 2030, rather than expiring on their current date. The changes apply only to cases where the injury causing disability occurred on or after the bill's effective date, which is July 1st of the year it becomes law. This legislation directly affects volunteer firefighters and the organizations that administer their benefit programs.
