Pursuant to the Federal Advisory Committee Act, Public Law 92-463, notice is hereby given that the SAB Hypoxia Advisory Panel will hold a public meeting to plan its work for developing a report that details advancements in the state of the science regarding hypoxia in the Northern Gulf of Mexico. The SAB was established by 42 U.S.C. 4365 to provide independent scientific and technical advice to the Administrator on the technical basis for Agency positions and regulations. The SAB is a Federal Advisory Committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The SAB will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

Background: EPA participates with other Federal agencies, state and tribes in the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force. In 2001, the Task Force released the Action Plan for Reducing, Mitigating and Controlling Hypoxia in the Northern Gulf of Mexico (or Action Plan available at​msbasin/​taskforce/​actionplan.htm). The Action Plan was informed by the science described in An Integrated Assessment of Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment (available at​products/​hypox_​finalfront.pdf) developed by the National Science and Technology Council, Committee on Environment and Natural Resources. Six technical reports provided the scientific foundation for the Integrated Assessment and are available at http.//​products/​pub_​hypox.html. The aforementioned documents provide a comprehensive summary of the state-of-the-science for the Gulf of Mexico hypoxic zone through about the year 2000.

EPA's Office of Water has requested that the SAB develop a report that evaluates the state-of-the-science regarding the causes and extent of hypoxia in the Gulf of Mexico, as well as the scientific basis of possible management options in the Mississippi River Basin. The SAB is asked to focus on scientific advances since 2000 that may have increased scientific understanding and control options in three general areas.

1. Characterization the Cause(s) of Hypoxia. The physical, biological and chemical processes that affect the development, persistence and extent of hypoxia in the northern Gulf of Mexico.

2. Characterization of Nutrient Fate, Transport and Sources. Nutrient loadings, fate, transport and sources in the Mississippi River that impact Gulf Hypoxia.

3. Scientific Basis for Goals and Management Options. The scientific basis for, and recommended revisions to, the goals proposed in the Action Plan; and the scientific basis for the efficacy of recommended management Start Printed Page 45544actions to reduce nutrient flux from point and nonpoint sources.

In developing its report on scientific advancements since 2000, the SAB is also asked to focus on the strengths and limitations of the science in managing the Gulf hypoxia problem, including available data, models and model results and uncertainty. The SAB is asked to pay particular attention to any new information that has emerged since or was not adequately considered in the last Integrated Assessment. In response to EPA's request, the SAB Staff Office has formed the SAB Hypoxia Advisory Panel. Background on the Panel formation process was provided in a Federal Register notice published on February 17, 2006 (71 FR 8578-8580).

Availability of Meeting Materials: Materials in support of this meeting will be placed on the SAB Web Site at:​sab/​ in advance of this meeting.

Procedures for Providing Public Input: Interested members of the public may submit relevant written or oral information for the SAB to consider during the advisory process.
