(f) Shipper shall have the option to either submit overrun quantities (nominations under firm

contracts in excess of its Maximum Daily Quantity (MDQ)) as a separate nomination or within the aggregate sum

day increments provided such nomination is within the begin and end dates of Shipper's Service Agreement.

standard nomination cycles. Such intraday nominations may be used to request increases or decreases in total

during that Gas Day. Shipper may make any such intraday changes only if the following requirements and
