San Antonio — NuStar Energy LP is looking at extending its anhydrous ammonia pipeline in Illinois. “We are currently in the process of submitting our permit application to the Illinois Commerce Commission, so the proposed expansion plans are still in the early stages of development and we do not have any details to provide at this time,” the company told Green Markets on Nov. 19. Initial reports were that a 60-mile pipeline was initially proposed to link from Shelbyville to an Archer Daniels Midland facility in Decatur, Ill. However, receiving property easements may be an issue, and sources said any initial plans for the route could be adjusted as a result.
