2012-49. Environmental Documents Prepared for Oil, Gas, and Mineral Operations by the Gulf of Mexico Outer Continental Shelf (OCS) Region

AGENCY:

Bureau of Ocean Energy Management, Interior.

ACTION:

Notice of the availability of environmental documents prepared for OCS mineral proposals by the Gulf of Mexico OCS Region.

SUMMARY:

The Bureau of Ocean Energy Management (BOEM), in accordance with Federal Regulations that implement the National Environmental Policy Act (NEPA), announces the availability of NEPA-related Site-Specific Environmental Assessments (SEA) and Findings of No Significant Impact (FONSI). These EA's were prepared during the period July 1, 2011, through September 30, 2011, for the following oil-, gas-, and mineral-related activities that were proposed on the Gulf of Mexico.

FOR FURTHER INFORMATION CONTACT:

Public Information Unit, Information Services Section at the number below. Bureau of Ocean Energy Management, Gulf of Mexico OCS Region, Attention: Public Information Office (MS 5034), 1201 Elmwood Park Boulevard, Room 250, New Orleans, Louisiana 70123-2394, or by calling 1-800-200-GULF.

SUPPLEMENTARY INFORMATION:

The BOEM prepares SEAs and FONSIs for proposals that relate to exploration, development, production, and transport of oil, gas, and mineral resources on the Federal OCS. These SEAs examine the potential environmental effects of activities described in the proposals and present BOEM conclusions regarding the significance of those effects. Environmental Assessments are used as a basis for determining whether or not approval of the proposals constitutes a major Federal action that significantly affects the quality of the human environment in accordance with NEPA Section 102(2)(C). A FONSI is prepared in those instances where BOEM finds that approval will not result in significant effects on the quality of the human environment. The FONSI briefly presents the basis for that finding and includes a summary or copy of the SEA. This notice constitutes the public notice of availability of environmental documents required under the NEPA Regulations.
