Noting that Oneok Field Services is planning a shutdown of the Bushton (KS) Plant beginning Jan. 1, Northern Natural Gas said Friday it "is anticipating potential operational problems caused by an unprecedented amount of gas processing plant shutdowns on its system."

However, the pipeline does anticipate a need to shut in supplies that do not meet quality specs. Problems include gas with high water content, entrained liquids, high percentages of heavier hydrocarbons and high Btu content, NNG said.
