The next of three multimillion-dollar natural gas transmission pipelines proposed in Warren County since 2006 will be explained by federal regulators at a public meeting Wednesday in Jackson.

Maps and information on the Midcontinent Express project will be available for landowners’ perusal at the meeting at 7 p.m. at the Eudora Welty Library on North State Street. Company managers and others involved in the environmental study will be on hand to answer questions.

Six sessions are planned today through Thursday at various points along the pipeline’s route. Other meetings are set for Quitman, Miss., Delhi, La., Minden, La., Mount Pleasant, Texas, and Paris, Texas.

Proposed by Kinder Morgan Energy Partners LP and Energy Transfer Partners LP, the approximately 500 miles of pipeline will carry about 1.4 billion cubic feet of natural gas daily from a hub in Bennington, Okla., just across the Texas line, to Butler, Ala., southeast of Meridian. Cost estimates total $1.2 billion.

Maps have the Midcontinent Express following roughly the same route along Entergy-owned rights of way through Warren County, also tracking the recently completed Gulf South pipeline. That line crosses the Mississippi River south of the river bridges and continues across U.S. 61 South just north of Grange Hall Road, then crosses Fisher Ferry Road, Mississippi 27 and the Hinds County line near the southern end of Bovina Cut-Off Road.

Maps at a March 2007 open house session in Vicksburg show a 30-inch line at its start, then a 42-inch line through northeast Texas and north Louisiana. It becomes a 36-inch line from Delhi to its endpoint in west Alabama.

Gulf South’s 42-inch, 242-mile East Texas to Mississippi Expansion Project, was put into full service Jan. 19. A compressor station at Tallulah is expected to be complete in months, company officials have said. Cost estimates were pegged at $800 million.

The Southeast Supply Header, built by a joint venture of Spectra Energy Corp. and CenterPoint Energy Inc., crosses the county’s southern tip at Yokena and is scheduled to begin carrying natural gas in June. About 105 miles of its 270-mile route from Delhi to Coden, Ala., just south of Mobile, is 42 inches, with the other 165 miles being 36 inches.

Both have daily carrying capacities of more than 1 billion cubic feet.

A copy of the draft study on the Midcontinent line is available at www.ferc.gov in the eLibrary section as docket number CP-08. Also, a link to the study can be found at www.midcontinentexpress.com.

Comments concerning the draft study may be submitted to FERC until Monday. A final environmental impact statement is expected from FERC by June 13.
