Persons interested in reviewing environmental documents for the

proposals listed above or obtaining information about EA's and FONSI's

prepared for activities on the Gulf of Mexico OCS are encouraged to

contact the MMS office in the Gulf of Mexico OCS Region.

FOR FURTHER INFORMATION CONTACT:

Public Information Unit, Information Services Section, Gulf of Mexico

OCS Region, Minerals Management Service, 1201 Elmwood Park Boulevard,

New Orleans, Louisiana 70123-2394, Telephone (504) 736-2519.

SUPPLEMENTARY INFORMATION: The MMS prepares EA's and FONSI's for

proposals which relate to exploration for and the development/

production of oil and gas resources on the Gulf of Mexico OCS. The EA's

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 the 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 EA. This notice constitutes the public notice of

availability of environmental documents required under the NEPA

Regulations.
