Mont Belvieu Storage Area, Texas

Mont Belvieu is perhaps the largest volatile hydrocarbon storage site in the country. Around 100 excavated cavities have been made inside the large salt dome that underlies the rise in the landscape that gives the town its name. Of these some are over 2,000 feet tall, holding more fluid than a supertanker. Several companies operate the storage cavities and the pipelines connected to them (e.g. LyondellBasell), that flow to and from the refineries of the Gulf Coast, and to markets elsewhere in the country. Mont Belvieu is one of dozens of salt domes along the gulf coast, many of which have been developed as oil drilling sites, and as underground gas and petrochemical storage
