South Florida Clean Coastal Waters Act of 2021

Introduced January 27, 2021

AI-Generated Summary

Updated February 7, 2026 at 9:38 PM UTC

The South Florida Clean Coastal Waters Act of 2021 directs the Inter‑Agency Task Force on Harmful Algal Blooms and Hypoxia to study and create a plan for reducing harmful algal blooms and low‑oxygen (hypoxia) conditions in South Florida’s waters. The effort covers the South Florida Water Management District, nearby coastal waters and the Florida Reef Tract, and involves federal, state, local, tribal, academic and private stakeholders.

Key Provisions

  • Amends the 1998 Harmful Algal Bloom and Hypoxia Research and Control Act to add a new Section 605 that defines “South Florida” and sets up the assessment and action‑plan requirements.
  • Requires the task force to deliver an interim integrated assessment within 540 days of enactment and a final assessment within three years, examining causes, impacts and research gaps.
  • Mandates a comprehensive action plan to be submitted within three years and 180 days, outlining monitoring needs, budget, model development, and a remote early‑warning system for public health.
  • Calls for the task force to consult with Florida state, local, tribal governments and regional stakeholders, avoid duplicating other programs, and ensure cost‑effective, technically sound solutions.
  • Requires publication of a plan summary in the Federal Register 180 days before submission and biennial progress reports to Congress.
  • Updates the table of contents of the 1998 Act’s Title VI to reflect the new South Florida section and renumbered sections.
