The annual yard line natural gas leak survey is under way in Hays. Midwest Energy crews will survey all the lines in the cities it serves with natural gas, beginning with Hays this week. Several rural lines also will be checked.

"The Department of Transportation requires that all lines be surveyed for leaks every three years," said Midwest spokesman Bob Helm. "Midwest Energy has chosen to survey yard lines every year throughout their system. The company has an excellent safety record with their natural gas and electric service, and this is just one more way to continue that performance."

Leaks are classified in several different categories. Those that need immediate attention, if found, are repaired immediately. Other leaks are repaired as necessary.

"The towns we have checked in the past are in really good shape. We have found very few leaks, and those were very small," Hellm said. "It's good to know the system is working the way it's supposed to. We do ask that residents leave their gates unlocked, and restrain their animals, so our crews can check the yard line up to the house."
