SUBJECT:   2002 TENTATIVE OUTAGE SCHEDULE

In February 2002, Columbia's Line BM-22 in Martin Co., KY will be out of

This includes the following lines: P-94, V-55 and BM-18.

In the spring of 2002, contingent upon the mining activity, Columbia's Line KA

valve on Line KA will be shut in.

In the spring of 2002, Columbia's Boldman Compressor located in Pike Co., KY,
will have one unit down for approximately two (2) months for annual maintenance
which results in a 15,000 Dth/d flow reduction.  Affected is Equitable's Hi-Hat

located on Columbia's Lines PM-3 and PM-17.

In May-June 2002, Columbia's Line's BM-18, Line VM-141 and Line V-55 will be
