The Bureau Ocean Energy Management (BOEM) has announced the publication of a final environmental assessment (EA) that considered the impacts of potential offshore wind leasing in federal waters of the Gulf of Mexico. The area that was reviewed in the EA included 30 million acres just west of the Mississippi River to the Texas/Mexican border. BOEM issued a Proposed Sale Notice in the Federal Register February 24, 2023. Wind Energy Areas have been identified based on stakeholder and ocean user input. They are located offshore Texas and Louisiana in areas that appear most suitable for wind energy development. The next step in the process is to issue a Final Sale Notice, sometime later this year.

In accordance with the National Environmental Policy Act (NEPA), BOEM prepares environmental documents on various actions related to the Outer Continental Shelf (OCS) Program. These documents may be Environmental Assessments or Environmental Impact Statements (EIS), depending upon the nature of the action in question or the significance of potential impacts associated with the action. It is the policy of BOEM to involve the public in preparing and implementing our NEPA procedures. In addition to posting opportunities for public participation on this web page, we typically place announcements in the Federal Register and/or in newspapers covering the areas potentially affected.

The Gulf of Mexico OCS Region of BOEM has been conducting environmental analyses of the effects of OCS oil and gas development since the inception of the NEPA of 1969. We have prepared and published more than 40 draft and final EIS. Our goal has always been to provide factual, reliable, and clear analytical statements in order to inform decision makers and the public about the environmental effects of proposed OCS activities and their alternatives. We view the EIS process as providing a balanced forum for early identification, avoidance, and resolution of potential conflicts. It is in this spirit that we welcome comments from all concerned parties.
