Harmful Algal Bloom and Hypoxia Research and Control Amendments Act of 2025

This bill amends the Harmful Algal Bloom and Hypoxia Research and Control Act of 1998 to strengthen federal efforts addressing harmful algal blooms (HABs) and hypoxia across marine, estuarine, and freshwater systems. It establishes a new Task Force required to develop a comprehensive Action Strategy every five years, examining causes, ecological impacts, and economic consequences of HABs in diverse environments including the Great Lakes, coastal waters, and freshwater systems. The bill authorizes $19.5 million annually for NOAA and $8 million annually for the EPA (fiscal years 2026-2030) to implement these provisions, creates a national monitoring network for HABs, and establishes an incubator program to develop innovative prevention strategies. It mandates consultation with states, tribes, local governments, and affected industries like fisheries and agriculture to address HABs impacts on public health, ecosystems, and communities.
