(a)	the transportation service is not a standard firm transportation service or an auction service;
(b)	the transportation service is used for the supply of natural gas for consumption by a market generating unit;
(c)	the terms and conditions for use of the transportation service are set out in a primary facility agreement made on or before 19 March 2018 and are the same, or substantially the same, as the terms and conditions in force on that date;
(d)	for each gas day in the service term that falls in the transitional firm service transition period, the contractual right to use the transportation service on that gas day under the primary facility agreement referred to in paragraph (c):
(i)	was in effect under the primary facility agreement on or before 19 March 2018; or
(ii)	is conditional only on the exercise of an option under the primary facility agreement to acquire the right where the option was acquired on or before 19 March 2018;
(e)	under the terms and conditions for use of the transportation service, to the extent a nomination for use of the transportation service is scheduled, nominations made by another transportation facility user for use of that or any other transportation service (other than a standard firm transportation service) will, in normal operating conditions, not affect the scheduled quantity; and
Note:
An example may be a service described in the natural gas industry as “as available” or “authorised overrun” (or services equivalent in nature to such services) where that service is treated as firm once scheduled.
(f)	at least one service point for the transportation service is either:
(i)	a service point on a pipeline by means of which the transportation service is provided at which gas is supplied for consumption by a market generating unit; or
(ii)	a service point at which gas is received onto a second transportation facility for transportation using a transitional firm service to a point on the second transportation facility, or a subsequent transportation facility, at which gas is supplied for consumption by a market generating unit.
(2)	A facility operator may classify a transportation service provided by means of the facility operator’s auction facility as a transitional firm service only where:
(a)	all the criteria for classification in subrule (1) are satisfied in relation to the transportation service;
(b)	notice has been given to the AER in accordance with rule 5(1) in relation to the transportation service of the facility operator’s intention to classify the service under this rule; and
(c)	the AER has not rejected the classification under rule 5(4) or revoked the classification under rule 7.
(3)	A facility operator may, in relation to a quantity of natural gas and a gas day, classify the quantity as a transitional firm quantity for the gas day only where:
(a)	the natural gas is nominated (including by renomination) for transportation using a transitional firm service;
(b)	the gas day is in the service term for the transitional firm service;
(c)	the quantity is equal to or less than the maximum daily quantity specified for the transitional firm service in the transitional firm service specification; and
(d)	the facility operator is reasonably satisfied at the time it makes the classification that the quantity to be transported is either:
(i)	to be withdrawn on the gas day at a pipeline service point solely for consumption by a market generating unit at that service point; or
(ii)	to be transported to another transportation facility from which it will be withdrawn on the gas day at a pipeline service point solely for consumption by a market generating unit.
(4)	For the purposes of subrule (3)(d), the facility operator may rely on information provided to it by the person making the nomination or another facility operator, where it is reasonable for the facility operator to do so.
(5)	A facility operator must make and maintain a record of the matters relied on by the facility operator for the purposes of subrule (3)(d) and must if requested by the AER provide the record to the AER.
(6)	If a facility operator becomes aware that any part of a quantity of natural gas previously classified as a transitional firm quantity no longer satisfies the criteria in subrule (3), it must, to the extent operationally and technically feasible, take that into account in scheduling and curtailment in accordance with the auction service priority principles and for the determination of auction quantity limits.
5	Notice to the AER about classification of a service
(1)	A facility operator who intends to classify a transportation service provided by means of the facility operator’s auction facility as a transitional firm service must give notice to the AER under this subrule no later than 30 business days before the facility operator first classifies any quantity of gas transported using the service as a transitional firm quantity.

and may contain any other matters relevant to the opinion.
(4)	If the AER is not satisfied that a transportation service the subject of a notice under subrule (1) satisfies the classification criteria in rule 4(1), the AER may by notice to the facility operator reject the classification. If a notice is given under this rule, the facility operator must not classify the transportation service as a transitional firm service.
(5)	If the AER does not give a notice under subrule (4) within 30 business days of the notice under subrule (1), the facility operator may classify the relevant transportation service as a transitional firm service and may continue to do so unless the AER rejects the classification under subrule (4) or revokes the classification under rule 7. The rejection or revocation takes effect at the time specified by the AER, which must not be earlier than the time the AER’s decision is notified to the facility operator.
6	Facility agreement amendment
(1)	A facility operator who has classified a transportation service as a transitional firm service must, within 5 business days after varying the facility agreement under which the transitional firm service is provided, give the AER written notice of the variation and if the variation is material, include a further notice to the AER updating the notice provided under rule 5(1).
(2)	For the purposes of subrule (1) a variation to a facility agreement is material if the relevant transitional firm service specification is no longer accurate.
7	Revocation of classification
(1)	The AER may revoke the classification of a transportation service as a transitional firm service if:
(a)	the AER is not satisfied that the criteria for classification in rule 4(1) are satisfied in relation to the transportation service (including by reason of a variation to a facility agreement); or
(b)	information provided to the AER under rule 5 or 6 was inaccurate or misleading in a material respect.
(2)	If the AER proposes to revoke a classification under subrule (1), it must notify the facility operator and invite the facility operator to make submissions about the proposed revocation within 10 business days of the notice.
(3)	If a facility operator given a notice under subrule (2) provides written submissions to the AER within the period required by the notice, the AER must have regard to those submissions in deciding whether to revoke the classification.
