Proposed Sanctuary Expansion

Building on more than 30 years of studies and numerous reports released in the last decade calling for additional protections, NOAA’s Flower Garden Banks National Marine Sanctuary is proposing to expand its boundaries to protect areas of national significance off the coasts of Texas and Louisiana in the Gulf of Mexico.

 

NOAA is proposing to add 15 additional banks, ranging from 70 to 120 miles off-shore, that are comprised of approximately 383 square miles of reefs and bottom features that provide habitat for fish and other biological resources that serve as engines of sustainability for much of the Gulf of Mexico.

NOAA is also proposing to extend the existing protections of Flower Garden Banks National Marine Sanctuary to these additional areas to limit the impact of bottom-disturbing activities on their sensitive biological resources and geological features.

Why Expand?

Currently Flower Garden Banks National Marine Sanctuary protects only three among dozens of reefs and banks scattered along the edge of the continental shelf of the northern Gulf of Mexico.

The Draft Environmental Impact Statement (DEIS) proposes expanding the network of protected areas within FGBNMS by incorporating additional nationally significant reefs and banks in the north central Gulf of Mexico. The proposed expansion alternatives would provide for more comprehensive management and protection of important habitat sites and cultural resources, and would provide opportunities for research and recovery of resources from observed impacts.

Expanding FGBNMS also supports several important aspects of Deepwater Horizon-related and wider Gulf of Mexico habitat restoration. In the Gulf of Mexico Ecosystem Restoration Task Force’s “Gulf of Mexico Regional Ecosystem Restoration Strategy,” the FGBNMS region is specifically mentioned as one of the critical areas that should be protected and managed as part of a network of ecologically significant offshore sites to enhance the Gulf’s overall biological productivity and resilience.

In the following video, shared with permission from Sir Patrick Pictures, Sanctuary Superintendent G.P. Schmahl explains the expansion proposal and the alternatives outlined below. (Video Length: 14:41)

Expansion Alternatives

The DEIS contains five alternatives that have been developed to meet the goals and objectives established by the Sanctuary Advisory Council and comments received during public scoping for sanctuary expansion. NOAA's preferred alternative is Alternative 3.

During development of the DEIS, sanctuary staff worked closely with constituents, particularly the oil and gas and fishing industries. Additionally, BOEM and BSEE participated in development of the DEIS as Cooperating Agencies.

    Sanctuary Expansion Process

    The process for Flower Garden Banks National Marine Sanctuary expansion was initiated following a recommendation from the Sanctuary Advisory Council's Boundary Expansion Working Group and has five basic steps:

    checkmark1. Scoping

    NOAA published a Notice of Intent to consider possible expansion of Flower Garden Banks National Marine Sanctuary in February 2015 and asked the public for input on potential boundaries; resources to be protected; issues NOAA should consider; and any information that should be included in the resource analysis.

    checkmark2. Proposed Expansion

    In response to public scoping, NOAA prepared a Draft Environmental Impact Statement (DEIS) that analyzes a range of expansion alternatives and proposed regulations and boundaries.

    arrow pointing down and to the right3. Public Review

    The public, agency partners and other stakeholders provided input on the DEIS during a 60-day public comment period. NOAA will consider all input and determine appropriate changes that address this input.

    4. PROPOSED RULEMAKING

    NOAA issues and takes public comment on a proposed rulemaking to implement the proposal prior to finalizing a decision. NOAA considers all input and determines appropriate changes that address this input.

    5. Sanctuary Expansion

    NOAA makes a final decision and prepares a final Environmental Impact Statement (EIS) and a final regulation package.

     

    NOAA's National Marine Sanctuary System

    The Office of National Marine Sanctuaries serves as the trustee for a network of underwater parks encompassing more than 170,000 square miles of marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa. The network includes a system of 13 national marine sanctuaries and Papahānaumokuākea and Rose Atoll marine national monuments.

    Through the National Marine Sanctuaries Act, NOAA can identify, designate and protect areas of the marine and Great Lakes environment that have special national significance.
