Consol Energy has begun using new, cleaner-burning engines to run its hydraulic fracturing pumps at natural gas well sites on Pittsburgh International Airport property.
The company says the diesel engines are supposed to cut harmful emissions by 36 percent.
They're developed jointly by Cummins Inc., which makes engines and fuel systems, and Halliburton, the oilfield services company.
Consol's chief operations officer of exploration and production, Tim Dugan, says the airport drilling sites are the company's "flagship project." The cleaner engines are being used on a six-well drilling site on the 9,000-acre airport site.
