Title 33 › CHAPTER 53 — HARMFUL ALGAL BLOOM AND HYPOXIA RESEARCH AND CONTROL › § 4004a

Summary

The Task Force must study and plan ways to reduce harmful algal blooms and low-oxygen zones in a defined South Florida area. "South Florida" means lands and waters inside the South Florida Water Management District, nearby coastal waters like Biscayne Bay, the Caloosahatchee Estuary, Florida Bay, Indian River Lagoon, St. Lucie River Estuary, and the Florida Reef Tract. Within 540 days after June 16, 2022, the Task Force must send an interim study to Congress and the President. Within 3 years after June 16, 2022, it must send a final study. The study must look at causes, effects, and ways to reduce these events, and check what is known and missing in research, monitoring, management, prevention, response, and control by federal and state agencies, regional research groups, universities, businesses, nonprofits, and Indian tribes. Using that study, the Task Force must give Congress a plan by 3 years and 180 days after June 16, 2022. The plan must cover monitoring needs, a schedule and budget for future tools, rules for making and checking models (including assumptions and data-quality steps), and a proposal for a remote monitoring and early warning system for local communities. While making the plan, the Task Force must work with Florida, local and tribal governments, and other stakeholders; avoid duplicating other federal or state work; identify needed research; consider cost-saving partnerships; use existing studies; publish a summary in the Federal Register at least 180 days before sending the plan to Congress; and report progress every two years after submission.
