**ACTION:**
Notice of the Availability of Environmental Documents. Prepared for OCS Mineral Proposals on the Gulf of Mexico OCS.
**SUMMARY:**
Minerals Management Service (MMS), 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), prepared by MMS for the following oil and gas activities proposed on the Gulf of Mexico OCS.
**FOR FURTHER INFORMATION CONTACT:**
Public Information Unit, Information Services Section at the number below. Minerals Management Service, Gulf of Mexico OCS Region, Attention: Public Information Office (MS 5034), 1201 Elmwood Park Boulevard, Room 114, New Orleans, Louisiana 70123-2394, or by calling 1-800-200-GULF.
**SUPPLEMENTARY INFORMATION:**
MMS prepares SEAs and FONSIs for proposals that relate to exploration for and the development/production of oil and gas resources on the Gulf of Mexico OCS. These SEAs examine the potential environmental effects of activities described in the proposals and present MMS conclusions regarding the significance of those effects. Environmental Assessments are used as a basis for determining whether or not approval of the proposals constitutes major Federal actions that significantly affect the quality of the human environment in the sense of NEPA Section 102(2)(C). A FONSI is prepared in those instances where MMS 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.
This listing includes all proposals for which the Gulf of Mexico OCS Region prepared a FONSI in the period subsequent to publication of the preceding notice.
