Breton Sound Area Block 20-21 Field Central Facility - Offshore Oil Extraction in Boothville, Louisiana

The Breton Sound Area Block 20-21 Field Central Facility is an operational oil extraction facility situated approximately 24.5 miles northeast of Boothville, Louisiana, in the Gulf of Mexico. This facility is part of the extensive offshore oil infrastructure in the United States, specifically within the Louisiana offshore region, which is a major hub for domestic crude oil production. The facility's primary function is to process and centralize oil extracted from the surrounding field, contributing to the overall supply chain of petroleum products. Operating under the jurisdiction of the U.S. Bureau of Safety and Environmental Enforcement (BSEE) and the Environmental Protection Agency (EPA), the facility must comply with federal regulations including the Clean Air Act (CAA) Refinery MACT standards and offshore safety requirements. The facility's technical specifications are typical for offshore central facilities in the Gulf of Mexico, which often include separation, dehydration, and storage capabilities. The Nelson complexity index for such facilities is generally moderate, reflecting the straightforward processing of crude oil without extensive refining. The environmental significance of this facility is tied to its offshore location, which poses inherent risks of oil spills and marine ecosystem impacts. The facility operates under MARPOL Annex I regulations for oil discharge prevention and must adhere to strict spill response plans. Its role in the regional energy grid is critical, as it supplies crude oil to refineries along the Gulf Coast, supporting both domestic fuel production and export markets. The facility's operational status ensures continued contribution to the United States' energy security.

Located in the Gulf of Mexico, the facility operates in a sensitive marine environment that supports diverse ecosystems including fisheries and marine mammals. Offshore oil extraction activities pose risks of oil spills, which can have devastating effects on coastal habitats and wildlife. The facility is subject to stringent environmental regulations under the Clean Water Act and Oil Pollution Act, requiring spill prevention and response plans. The proximity to the Mississippi River Delta adds complexity due to sediment transport and coastal erosion dynamics.
