The natural gas industry has successfully stored natural gas in facilities for nearly 90 years. Sempra Energy (majority owner of Liberty Gas Storage) has safely and efficiently built and operated similar gas storage facilities in California and Michigan. Sempra Energy and its affiliate companies take pride in an excellent environmental and safety record, and ensure continued dedication to performing at the highest safety levels.

There are now 23 salt-cavern, natural gas storage projects in the United States, with 20 along the Gulf Coast that have a solid safety record. The Liberty Gas Storage facility employs the newest technologies. Liberty Gas Storage has engineered and built the facility to regulatory and modern industry-safety standards.

Salt-dome structures have been used commercially for many years and offer these benefits:

• The existing brine caverns are suitable and available for conversion to natural gas storage, making this gas storage facility one of the lowest risk and fastest to use of all potential salt-storage projects along the Gulf Coast.
• Lessen environmental impact: The caverns are pre-existing and, therefore, no extra digging or construction is required.
