The purpose of this legislation is to expand the definition of a major disaster under the Robert T. Stafford Disaster Relief and Emergency Assistance Act to include algal blooms. Algal blooms are harmful overgrowths of algae in water bodies that can pose serious health risks to humans and wildlife, as well as negatively impact local economies and ecosystems. The key provision of this legislation is the amendment to the existing law that allows algal blooms to be recognized as a major disaster.
