physical flows on Transporter's system upon at least one hour prior notice

with penalties, for failure of performance; and (ii) has the capability to

verify the change in flow by real-time validation to Transporter through

electronic telemetry equipment, provided that for the purpose of

satisfying the proximate zone standard, zones 4 and 5 shall be considered

a single zone and zone 3 shall be considered adjacent to zones 2 and 4.

Transporter shall not be required under any circumstances to receive gas

at any Receipt Point where the total quantity of gas for transportation

scheduled for receipt on any day is less than that required for the

accurate measurement of quantities to be received.

covered by a Balancing Agreement and have flow control are eligible for

Hourly Scheduling Flexibility Service under this Rate Schedule.

required from time to time to enable the gas to enter Transporter's

facilities at the Receipt Point. Transporter shall deliver gas to Shipper

or Shipper's designee at Transporter's line pressure existing at the
