Pennsylvania is competing with Ohio and West Virginia for the location of a Shell petrochemical plant that, according to one report, will bring 10,000 construction jobs, hundreds of full-time plant jobs, and thousands of additional spin-off jobs to the winner.

“The chemical industry association ACC [American Chemistry Council] has done studies that estimate a ‘multiplier effect’ of 5.5 for induced and indirect jobs,” wrote Kayla Macke, media relations coordinator for Shell.
