one or more existing receipt or delivery points or (2) request and pay for

additional primary capacity.

business day following the amendment request date except for limitations

explained in § 6.12, which will be posted the third business day following the

bid period.

(d) Southern Trails will not allow amendments to contracts if

the result of the requested amendment impairs Southern Trails' ability to

provide firm service. Any capacity at receipt and delivery points that

becomes available through the expiration of a firm transportation agreement

will be sold according to the bidding procedures outlined in §§ 6 and 8, and

shall not be available for primary receipt or delivery point changes unless

Southern Trails, without undue discrimination, agrees otherwise.

11.3 Flexible Use of Alternate Receipt and Delivery Points. A firm

Shipper, or any replacement Shipper, may flex to or use any receipt or

delivery point on an alternate basis at which capacity is available. A

replacement Shipper may not add or delete primary receipt and delivery points

or change Shipper's RDC at primary receipt and delivery points unless the

terms of Shipper's release allow for such.
