Referred to the House Committee on Transportation and Infrastructure.
Requires the Secretary of the Army, through the Chief of Engineers, to stop discharging water from Lake Okeechobee through the S-308 and S-80 lock-and-dam structures whenever microcystin levels exceed the EPA’s recommended maximum for recreational waters. The determination may be based on water tests conducted by the Secretary, another federal agency, or the State of Florida and uses the EPA guidance cited (84 Fed. Reg. 26413 or successor criteria).
The Secretary of the Army, acting through the Chief of Engineers, shall prohibit discharges of water from Lake Okeechobee through the S-308 and S-80 lock and dam structures when the water exceeds the maximum concentration of microcystins recommended for recreational waters by the Environmental Protection Agency.
The trigger for the discharge prohibition is when water exceeds the maximum concentration of microcystins recommended for recreational waters by the Environmental Protection Agency as described in the notice titled 'Recommended Human Health Recreational Ambient Water Quality Criteria or Swimming Advisories for Microcystins and Cylindrospermopsin' (84 Fed. Reg. 26413) or any successor water quality criteria.
The determination that the water exceeds the EPA recommended microcystin concentration may be based on tests conducted by the Secretary of the Army, another Federal agency, or the State of Florida.
Who is affected and how:
Coastal shoreline communities and recreational users: Likely benefit from fewer toxic algal blooms and reduced exposure to microcystin in estuaries fed by Lake Okeechobee discharges. Reduced toxin loading can protect beaches, marinas, and tourism.
Public water systems and local governments: Utilities that draw from affected water bodies may see improved public-health protection; they may also need to coordinate with state and federal authorities on monitoring and public advisories.
Commercial and recreational fishers and aquatic ecosystems: May experience improved water quality and reduced risks to fisheries and aquatic life, but altered discharge schedules can change salinity and habitat conditions with ecological and economic effects.
United States Army Corps of Engineers and water managers: Operational constraints on discharges create new requirements to base release decisions on toxin test results. This can complicate flood-risk management, lake-level control, and water delivery obligations to agricultural and urban users.
State agencies (Florida) and federal monitoring labs: Will play a role in testing and producing determinations; coordination and data-sharing become important.
