A Pennsylvania lawmaker is calling for additional funding for gas pipeline safety.

U.S. Sen. Bob Casey made the announcement Friday at the Gross Towers Senior Center in Allentown.

A man was killed in a gas explosion at the highrise in 1994, and five people were killed in a gas explosion three years ago at 13th and Allen streets in Allentown.

Casey said he sent a letter to the federal office of management and budget, urging it to give additional funds to the federal agency that oversees pipeline safety.

"More inspectors, re-monitoring, more making sure that strategies we put in place to prevent this kind of an explosion have the funding behind them to make them effective," Casey said.

Casey said UGI has replaced 20 miles of cast iron pipeline in Allentown since the 2011 explosion and is continuing to replace pipeline throughout the city.
