   a/ Total as of December 31.
   b/ Total underground storage capacity at the end of each
  calendar year (in billion cubic feet):  1995 - 7,953; 1996 -
  7,980; 1997 - 8,332; 1998 - 8,179; 1999 - 8,229; and 2000 -
  8,246.
   c/ Negative numbers indicate the volume of injections in
  excess of withdrawals. Positive numbers indicate the volume of
  withdrawals in excess of injections.
   d/ Reflects one respondent's reclassification of natural gas
  in underground storage from working gas to base gas.
   E/  = Estimated Data.
  RE/  = Revised Estimated Data.
   NA  = Not Available.
   __  = Not Applicable.





      Notes:  Data for 1995 through 1999 are final.  All other
  data are preliminary unless otherwise noted.  Estimates for the
  most recent two months are derived from the Short-Term
  Integrated Forecasting System (STIFS). See Natural Gas Monthly,
  Appendix A Explanatory Note 7 for a discussion of revision
  policy.  Gas in storage at the end of a reporting period may
  not equal the quantity derived by adding or subtracting net
  injections or withdrawals during the period to the quantity of
  gas in storage at the beginning of the period.  Totals may not
  equal sum of components because of independent rounding.
  Geographic coverage is the 50 States and the District of
  Columbia.
