Harmful Algal Blooms and Hypoxia Research and Control Amendments Act of 2011 - (Sec. 4) Amends the Harmful Algal Bloom and Hypoxia Research and Control Act of 1998 to set forth as the purposes of such Act: (1) to provide for the development and coordination of a comprehensive and integrated national program to address harmful algal blooms and hypoxia; (2) to provide for the assessment of environmental, socioeconomic, and human health impacts of harmful algal blooms and hypoxia and to integrate such assessment into marine and freshwater resource decisions; and (3) to facilitate efforts to develop and implement harmful algal bloom and hypoxia response plans, strategies, and tools.
(Sec. 5) Revises requirements concerning membership of the Inter-Agency Task Force on Harmful Algal Blooms and Hypoxia, including requiring the Task Force to have a representative from the Centers for Disease Control (CDC).
(Sec. 6) Requires the Task Force to: (1) establish the National Harmful Algal Bloom and Hypoxia
Gives the National Oceanic and Atmospheric Administration (NOAA) the primary responsibility for administering the Program. Requires the Under Secretary of Commerce for Oceans and Atmosphere to:
Requires the Administrator of the Environmental Protection Agency (EPA), in consultation with the Under Secretary, to: (1) carry out the duties assigned to the Under Secretary under this Act and the Harmful Algal Bloom and Hypoxia Research and Control Act of 1998; (2) research the ecology of freshwater harmful algal blooms; (3) monitor and respond to freshwater harmful algal blooms events in lakes (except for the Great Lakes), rivers, and reservoirs; (4) mitigate and control freshwater harmful algal blooms; and (5) recommend the amount of funding required to carry out cooperative efforts for inclusion in the President's annual budget request to Congress.
(Sec. 7) Requires the Under Secretary to develop and submit to the Task Force for approval a research and action plan for each region. Requires the Under Secretary to identify appropriate elements for each region, including: (1) baseline research needed to understand the biological, physical, and chemical conditions that cause, exacerbate, and result from harmful algal blooms and hypoxia; (2) priorities for ecological and socioeconomic research on issues related to, and impacts of, harmful algal blooms and hypoxia; (3) research, development, and demonstration activities needed to develop and advance technologies for minimizing the occurrence of harmful algal blooms and hypoxia and for improving capabilities to predict, monitor, prevent, control, and mitigate harmful algal blooms and hypoxia; and (4) state, tribal, and local government actions that may be implemented to monitor, minimize, reduce, and address harmful algal blooms and hypoxia.
Requires the Under Secretary to: (1) begin developing the regional research and action plans for at least a third of the regions within nine months after enactment of this Act, beginning with regions that historically have the greatest record of harmful algal blooms or the largest perennial hypoxic zones; (2) begin developing the regional research and action plans for at least another third of the regions within 21 months; (3) begin developing the regional research and action plans for the remaining regions within 33 months; and (4) ensure that each regional research and action plan developed is completed and approved by the Task Force within 12 months after the date that development of the regional research and action plan begins and updated at least once every five years after completion.
Requires the Under Secretary to make funding available to eligible organizations to implement the research, monitoring, forecasting, modeling, and response actions included under each approved regional research and action plan.
(Sec. 8) Requires the Under Secretary, within two years of the submission of the action strategy, to report to the appropriate congressional committees on the annual Task Force meetings, the activities carried out under the Program and the regional research and action plans, the progress made on implementing the action strategy, and any need to revise or terminate activities or projects under the Program. Requires the Task Force to report to Congress within five years after enactment of this Act on harmful algal blooms and hypoxia in marine and freshwater systems.
(Sec. 9) Requires the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force, within 12 months after enactment of this Act and biennially thereafter, to report to appropriate congressional committees and the President on the progress made by Task Force-directed activities carried out or funded by EPA and other state and federal partners toward attainment of the Coastal Goal of the Gulf Hypoxia Action Plan of 2008.
(Sec. 10) Authorizes the departments and agencies represented on the Inter-Agency Task Force to participate in interagency financing and to share, transfer, receive, obligate, and expend funds appropriated to any member of the Task Force for the purposes of carrying out administrative or programmatic projects or activities under such Act.
(Sec. 11) Authorizes appropriations for the Program.
