Pittsburgh Business Times ace reporter Paul Gough has done it again–breaking big news related to ExxonMobil and their very active search to locate a site in the Pittsburgh region to build a gigantic ethane cracker plant. This time Paul’s sources are telling him Exxon has widened their search. A few weeks ago we told you Exxon was looking for potential locations in Beaver County, PA, near where Shell is building their $8 billion cracker plant (see Exxon Mobil Sniffing Around SWPA to Build Second Cracker Plant). Paul learned the search has widened to at least two other southwest PA counties.
