The U.S. Department of the Interior's Minerals Management Service (MMS) has completed an environmental review of seven proposed oil and gas lease sales in the Central Gulf of Mexico Planning Area (CPA) and the Western Gulf of Mexico Planning Area with the publication of a Supplemental Environmental Impact Statement (SEIS).
The SEIS is a result of the Gulf of Mexico Energy Security Act of 2006, which mandated approximately 5.8 million acres located in the southeastern part of the CPA be offered for lease. This acreage, known as the 181 South Area, was not analyzed in the original 2007-2012 Multisale EIS. MMS prepared the SEIS to analyze the potential environmental effects of oil and natural gas leasing, exploration, development, and production in the 181 South Area.
The SEIS also analyzes any new information available for the remaining seven lease sales proposed for 2009-2012 in the Western and Central Gulf of Mexico offshore the States of Texas, Louisiana, Mississippi, and Alabama.
Comments from Federal, State, and local government agencies and other interested parties were considered in determining the significant issues and alternatives for analysis in the SEIS.
