LA Storage LLC (LA Storage) is seeking Federal Energy Regulatory Commission (FERC) approval to construct and operate new natural gas storage and transmission facilities associated with its Hackberry Storage project, located in Cameron and Calcasieu Parishes, Louisiana. LA Storage plans to convert three existing salt dome caverns to natural gas storage service and develop one new salt dome cavern, as well as construct approximately 11.1 miles (17.9 km) of 42-in. (1.1-m) natural gas pipeline, compression, and appurtenant facilities. The purpose of the Hackberry Storage project will be to inject and withdraw natural gas into storage at a planned rate of approximately 1.5 Bcf/d (4.2 x 107 m3/d).
The gas storage facility will include the four salt dome natural gas storage caverns, as well as the Pelican Compressor Station (CS), which will be required for injection and withdrawal of natural gas to and from the caverns and pipeline. The 21,400-hp (15,964-kW) Pelican CS will house four 5350-hp (3991-kW) Caterpillar 3616 reciprocating compressor units, as well as dehydration equipment, leaching equipment, a brine pumping system, pressure regulator equipment, bidirectional cavern gas lines, brine return lines, filter separators, gas heaters, tankage, electrical equipment, one 1000-kW diesel backup generator, one pig launcher/receiver assembly for each of the 42-inch natural gas pipelines (two total), contractor staging and pipe storage areas, spoil storage areas, six mining water supply wells, and additional auxiliary equipment as required for compressor station functionality.
