^aLNG totals should not be added to underground  storage, because LNG is normally used to satisfy peak demand when underground storage is also being used.
^bPeak day deliverability at 11,585 million cubic feet per day is available only for about 8 days. For the remainder of the winter, without LNG, peak day deliverability is 8,167 million cubic feet per day.
