HARRISBURG — Pennsylvania might have an opportunity to land a multibillion-dollar chemical manufacturing plant, thanks to the increasing flow of natural gas from the Marcellus Shale formation.

The Patriot-News of Harrisburg reports state Secretary of Community and Economic Development Alan Walker said Friday that three large international chemical companies have expressed interest in such an investment.

He made the comments during the third meeting of Gov. Tom Corbett's Marcellus Shale Advisory Commission. Walker says an aide is working to persuade a manufacturer to build in Pennsylvania.

The natural gas industry received more good news at the meeting from Secretary of Conservation and Natural Resources Richard Allan. He says his agency is preparing a plan to replace its aging fleet of trucks with a fleet powered by natural gas.
