Mississippi officials don't expect a decision before the end of September on whether part of the nation's strategic petroleum reserve will be stored in the Richton salt dome.
Richton is one of two sites under consideration in Mississippi. The U.S. Department of Energy in 2005 added the Bruinsburg salt dome near the Mississippi River just south of Vicksburg as a possible location.
The other salt dome sites being considered are Chacahoula and Clovelly in Lafourche Parish, La., and Stratton Ridge in Brazoria County, Texas.
In Mississippi, there are about 50 salt domes used for petroleum product storage, according to state officials. The Richton site could store 160 million barrels, roughly 16 percent of the one billion barrel target, officials said.
The Richton dome is a 1,500-acre site located off Mississippi 42, west of Richton. The site was studied in the late 1970s as a possible storage site for nuclear waste and again in the early 1990s as a petroleum storage site.
"We are still hoping, but we've not heard anything," Mayor Jimmy White said.
