The water company also announced that it is applying for a grant from the state Department of Environmental Protection to add more CNG-powered vehicles to its fleet.
In December, DEP launched its natural-gas-vehicle grant program, which will provide $20 million over three years, including $10 million in the first year, to help cover purchase and conversion costs for fleet vehicles.
The program is funded by Act 13, the natural-gas law passed last February that authorized counties to levy impact fees on the deep wells drilled to tap Marcellus Shale deposits.
Pennsylvania American is planning to construct a company-owned fueling station in Scranton that will support up to 36 CNG vehicles in 2014, said Steve Tambini, vice president of company operations.
"The new CNG vehicles operate on the same basic principle as traditionally fueled trucks, but they generate significantly less particulate matter," he said. "This means cleaner air and a reduction in greenhouse gas emissions, which will benefit the environment and the communities we serve."
