Shell Chemicals has agreed to pay all of the cost in relocating a Pennsylvania water source in order to build an ethane cracker on the site.
The Center Township Water Authority will get a new water intake site and a new treatment plant.
Officials said Shell is funding all but $3 million of the $72 million project in Beaver County. The authority will pick up the rest of the tab.
Shell could end up using the water facilities if it moves forward with a multibillion-dollar petrochemical facility at the former Horsehead Corp. site in Potter Township.
