Project Scope

Graycor Industrial performed critical excavation and foundation work for the $365 million natural gas liquids processing and production facility. The project was completed within Aux Sable′s aggressive six-month timeframe.

One of the largest U.S. facilities of its kind, the Aux Sable Liquid Products plant in Channahon, Illinois, is one of the most significant propane suppliers in the Midwest. Connecting with the Alliance Pipeline system, Aux Sable′s plant serves U.S. and Canadian markets and reduces the Midwest′s reliance on NGL imports.
