36.1 Purpose.

(a) This Section provides for the recovery of costs incurred for the transmission and compression

of gas by others (Account No. 858 costs or 858 costs), applicable to Operational 858 costs, which shall be

defined as including amounts paid to upstream pipelines for contracts retained as a result of Transporter's

Order No. 636 restructuring, or utilized in Transporter's post-restructuring operations.

(b) Transporter shall recover Transportation Costs, including carrying charges calculated under

Section 154.501 or successor provision of the Commission's regulations, by means of rates and charges

applicable to Shippers under (i) Transporter's FTS, NTS, NTS-S, TPS, SST, GTS, OPT, and ITS Rate Schedules as

set forth in Volume No. 1 of this Tariff, and (ii) those X-Rate Schedules set forth in Volume No. 2 of this

Tariff that incorporate rates from Volume No. 1 of this Tariff (collectively the Applicable Rate Schedules).

The rates for recovery of Transportation Costs, as set forth at Sheet Nos. 25 through 28, inclusive, of this

Tariff, shall be established by Transporter's Section 4(e) rate filings. Recovery of adjustments to those

base rates and of unrecovered amounts from preceding periods shall be effected through the Transportation Cost

a TCRA with the Commission (i) annually on or before March 1, to become effective April 1 (Annual TCRA

Filing), and (ii) at such other times as Transporter in its reasonable discretion determines necessary to

become effective 30 days after filing (Periodic TCRA Filing).

36.3 Accounting for Activity. Transporter will account for all under or over recovered Transportation Costs

in Account No. 186.

(Current Operational TCRA Rate) as adjusted by any TCRA Filing, and (ii) the unrecovered Operational 858 costs

includable in the Transportation Costs rate (Operational TCRA Surcharge) as adjusted through the Annual TCRA.

These shall be calculated for TCRA Filings in the following manner:
