shall be scheduled after the nominations received before

the nomination deadline. (NAESB 1.3.6)

All nominations shall be considered original

nominations and shall be replaced to be changed. When a

nomination for a date range is received, each day within

that range is considered an original nomination. When a

subsequent nomination is received for one or more days

within that range, the previous nomination is superseded by

the subsequent nomination only to the extent of the days

specified. The days of the previous nomination outside the

range of the subsequent nomination are unaffected.

Nominations have a prospective effect only. (NAESB 1.3.7)

Intra-day nominations can be used to request

increases or decreases in total flow, changes to receipt

points, or changes to Delivery Points of scheduled gas.

intra-day nominations span one day only). Intra-day

nominations do not replace the remainder of a standing

nomination. There is no need to re-nominate if intra-day

nomination modifies existing nomination. (NAESB 1.3.13)
