Mont Belvieu

Pipeline Emergency:  In the event of an emergency involving an Equistar Chemicals pipeline, call 800-525-7516.

The Mont Belvieu Storage Facility is one of two storage locations operated by the LyondellBasell pipeline group in the Texas Gulf Coast region. 

Mont Belvieu is home to one of the largest natural salt domes in the nation. The Barbers Hill dome was discovered in 1902, and with about 120 caverns, it stretches more than two miles wide. 

The LyondellBasell Mont Belvieu facility is 42 acres and has the potential storage capacity of about 14.5 million barrels of liquid hydrocarbons, which is equivalent to 609 million gallons of milk, or it could fill approximately 900 Olympic-sized swimming pools. 

There are 10 wells at the site that together provide approximately 9.3 million barrels of storage capacity. The pipeline system and the Mont Belvieu storage site are operated 24 hours a day from the pipeline operations control center in LyondellBasell's Clear Lake Facility in Houston, Texas. The control center can start and stop pumps and compressors along the pipeline and to remotely open and close valves and isolate sections of pipeline or divert flows to other lines as needed. 

Our control center also has advanced communications equipment to maintain constant communications with the public and emergency responders in the event of an emergency.
