Caillou Island Tank Battery #21 - Oil Extraction Facility in Cocodrie, Louisiana

Caillou Island Tank Battery #21 is an oil extraction facility located in Cocodrie, Louisiana, within the Caillou Island Field. The facility is situated in Terrebonne Parish, a region known for its extensive oil and gas infrastructure in the Gulf Coast area. As a tank battery, it collects and temporarily stores crude oil from nearby wells before transport. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA) and the Bureau of Safety and Environmental Enforcement (BSEE) for offshore and coastal operations. It is subject to the Clean Air Act (CAA) Refinery MACT standards and other emissions regulations. The facility's NAICS codes (211111 and 211120) indicate crude petroleum and natural gas extraction. Located in a coastal wetland environment, the facility's operations are significant for local energy production but also pose potential risks to sensitive ecosystems. Spill prevention and response measures are critical given the proximity to the Gulf of Mexico and marshlands. The facility contributes to the regional oil supply chain, supporting downstream refining and distribution.

The facility is situated in the Mississippi River Delta region, characterized by coastal marshes and estuaries that support diverse wildlife. Oil extraction activities in this area require careful management to prevent spills and minimize habitat disruption. The proximity to the Gulf of Mexico increases spill risk, necessitating robust containment and response protocols under BSEE oversight.
