AGL Resources subsidiary Jefferson Island Storage & Hub, LLC (JISH) today announced that it has filed a permit application with the Louisiana Department of Natural Resources to expand its natural gas storage facility near the Henry Hub.

JISH currently operates two natural gas storage caverns in the Jefferson Island salt dome approximately 4,000 feet below the surface of Lake Peigneur in Iberia Parish.

The existing caverns have operated safely since 1994.

"We are confident that the environmental, safety and water-usage data that we have submitted with our permit application will demonstrate that Jefferson Island is among the most suitable sites for new storage caverns in the region," said Dana Grams, president of Pivotal Energy Development, a division of AGL Resources company, which owns and operates JISH. "Throughout the permitting process, we will continue to work with the local community so our neighbors fully understand what the project entails and our ongoing commitment to being a good corporate citizen."

Grams also noted that the addition of two caverns at a storage site that is so closely connected to the Henry Hub and is currently in operation should provide JISH with a competitive edge in the marketplace and provide needed storage capacity to the nation's natural gas infrastructure.

Pending state approval, the new caverns could enter commercial operation within five years, expanding the working gas capacity at JISH from approximately 8 billion cubic feet to approximately 20 Bcf.

The proposed expansion at JISH is expected to offer significant economic impact to Vermilion and Iberia Parishes, according to an independent study. The anticipated benefits include:

  --  creation of more than 200 direct and an additional 140 indirect jobs
      for the local economy during the four to five years of cavern
      construction
  --  addition of approximately $93 million to the local economy from
      construction and development expenditures
  --  contribution of as much as $2.5 million per year to the local economy
      from ongoing operations and maintenance activities
  --  generation of increased sales and property tax revenues

In November 2009, the Louisiana Mineral and Energy Board approved an operating agreement between JISH and the state that enabled the company to resume its efforts to gain the regulatory approvals needed to proceed with its planned expansion.

As part of the operating agreement, JISH agreed to several benefits specifically for local residents, including:

  --  Restriction of the use of future caverns to store only natural gas
  --  Commitment to limit average daily withdrawal of water from the Upper
      Chicot aquifer to 3 million gallons per day during cavern creation

In May, the company drilled a test well that validated its assumptions that the non-potable water from the Lower Chicot aquifer can be used for the balance of water needed to carve out the caverns in the salt dome without adversely impacting the Upper Chicot -- the area's main water source for residential, commercial and agricultural uses.
