GENERAL TERMS AND CONDITIONS (Continued)

36. MARKET SEGMENTATION

1. A Customer receiving firm transportation service under Part 284 of

the Commission's regulations may elect, in accordance with the

provisions listed below, for its account or for the purpose of

implementing a capacity release transaction, to segment its

contractual entitlements into two segments as follows:

A. Receipt Segment. The receipt segment shall be from the point in

which gas is received into the Equitrans system and delivered to

either the Equitrans Market Aggregation Point or Equitrans

storage. The receipt segment shall be limited to Customer's MDQ

and shall be subject to applicable usage charges, fuel retainage

and surcharges.

B. Delivery Segment. The delivery segment shall be from either the

Equitrans Market Aggregation Point or Equitrans storage to the

Customer's primary or approved secondary delivery point. The

delivery segment shall be limited to Customer's contractual MDQ.

Usage charges, fuel retainage and surcharges shall not be

applicable to the delivery segment.

2. Customer may exercise market segmentation by making a nomination to

utilize either an applicable Receipt Segment or an applicable

Delivery Segment, consistent with Customer's rights and obligations

under its existing service agreements contractual entitlements, not

to exceed Customer's contractual MDQ, and posting and releasing the

unused segment under Section 22 of the General Terms and Conditions.

Where market segmentation is achieved through a capacity release, the

Releasing Customers shall be entitled to receive contingent credit

for Reservation charges received by the Pipeline from the Replacement

Customer, in accordance with the applicable Capacity Release Service

Agreement. Segmented service entitlements shall be treated as all

other services under this tariff for purposes of nomination,

scheduling and operational flow orders.

3. The Market Aggregation Points are not physical delivery points on

Equitrans' system, but rather nomination points where natural gas

supplies are aggregated for transportation to downstream delivery

points. The shipper nominating gas to a Market Aggregation Point

will be charged Rate Schedule LPS rates on all daily imbalances

created by such nominations at the Market Aggregation Point.

4. Segmentation is limited to contiguous sections of the Equitrans'

system where gas can physically flow without imposing conditions

that may threaten the operational integrity of the Equitrans' system.

5. Nothing in this Section shall be interpreted to preclude Equitrans

from issuing an OFO in accordance with Section 11 of the General

Terms and Conditions.

6. Section 7.2 of the General Terms and Conditions of this tariff

describes the conditions under which shippers may nominate service

using secondary receipt and delivery points.
