To All Customers of ANR Pipeline Company:

	Effective May 1, 2001 production, ANR Pipeline Company will bill process plant PTR transportation on a current month basis, thereby eliminating the invoicing lag previously in effect.   This is pursuant to Section 17.1 of the General Terms and Conditions of its FERC Gas Tariff that "Transporter shall render to Shipper a statement of the amount due for the preceding Month under the applicable Rate Schedule(s)."  Invoices will be based on actual allocated volumes, if available; otherwise nominated and scheduled volumes will be utilized with an adjustment to actuals in the succeeding month.

	Any questions regarding this posting should be directed to Kay Dennison at (832)676-2619.
