NEW YORK, July 3 (Reuters) - NiSource Inc unit Columbia Gas Transmission LLC on Wednesday said it discovered a leak on its natural gas pipeline segment 1711 near Homer City, Pennsylvania.

In a website posting the company said production into the line between the Homer City interconnect and the Young Womans Creek interconnect with Transcontinental Gas Pipeline could be impacted. Meters located south of the leak will continue to flow, however one meter in the area of the leak was isolated and shut in.

The company urged gas shippers to use production meters north of the Homer City interconnect, noting production nominated south of the leak could have a greater potential for restriction.

An operational advisory was issued due to the leak. Advisories, or alerts, are issued by pipeline companies in order to protect the integrity of the line by requiring shippers to balance their supply with customers' usage.

A company spokeswoman was not immediately available with further information.

The near 12,000-mile Columbia Gas system transports an average of 3 billion cubic feet per day of natural gas in 10 U.S. Northeastern, mid-Atlantic and Midwestern states.
