199—19.13 (476) Transportation service.
	 19.13(1) Purpose. This subrule requires gas distribution utility companies to transport natural gas owned by an end-user on a nondiscriminatory basis, subject to the capacity limitations of the specific system. System capacity is defined as the maximum flow of gas the relevant portion of the system is capable of handling. Capacity availability shall be determined using the total current firm gas flow, including both system and transportation gas.
	 19.13(2) End-user rights. The end-user purchasing transportation services from the utility shall have the following rights and be subject to the following conditions:
	  a.   	 The end-user shall have the right to receive, pursuant to agreement, 100 percent of the gas delivered by it or on its behalf to the transporting utility (adjusted for a reasonable volume of lost, unaccounted-for, and company-used gas).
	  b.   	 The volumes which the end-user is entitled to receive shall be subject to curtailment or interruption due to limitations in the system capacity of the transporting utility. Curtailment of the transportation volumes will take place according to the priority class, subdivision, or category which the end-user would have been assigned if it were purchasing gas from the transporting utility.
	  c.   	 During periods of curtailment or interruption, the party is entitled to a credit equal to the difference between the volumes delivered to the utility and those received by the end-user, adjusted for lost, unaccounted-for, and company-used gas. The credit shall be available at any time, within the conditions of the agreement.
	  d.   	 The end-user shall be responsible for all costs associated with any additional plant required for providing transportation services to the end-user.
	 19.13(3) Transportation service charges. Transportation service shall be offered to at least the following classes:
	  a.   	 Interruptible service with system supply reserve.
	  b.   	 Interruptible service without system supply reserve.
	  c.   	 Firm service with system supply reserve.
	  d.   	 Firm service without system supply reserve.
	 19.13(4) Transportation service charges and rates. All rates and charges for transportation shall be based on the cost of providing the service.
	  a.   	 “System supply reserve” service shall entitle the end-user to return to the system service to the extent of the capacity purchased. The charge shall be at least equal to the administrative costs of monitoring the service, plus any other costs (including but not limited to gas demand costs which are directly assignable to the end-user).
	  b.   	 End-users without system supply reserve service may only return to system service by paying an additional charge and are subject to the availability of adequate system capacity. An end-user wishing to receive transportation service without system supply reserve must pay the utility for the discounted value of any contract between the utility and the end-user remaining in effect at the time of beginning transportation service. The discounted values shall include all directly assignable and identifiable costs (including but not limited to gas costs).
	  c.   	 The utility may require a reconnection charge when an end-user receiving transportation service without system supply reserve service requests to return to the system supply. The end-user shall return to the system and receive service under the appropriate classification as determined by the utility.
	  d.   	 The end-user electing to receive transportation service shall pay reasonable rates for any use of the facilities, equipment, or services of the transporting utility.
	  e.   	 Small volume transportation service. Rescinded IAB 4/28/04, effective 6/2/04.
	  f.   	 Optional plan filing. Rescinded IAB 4/28/04, effective 6/2/04.
	 19.13(5) Reporting requirements. A natural gas utility shall file with the board two copies of each transportation contract entered into within 30 days of the date of execution. The utility may delete any information identifying the end-user and replace it with an identification number. The utility shall promptly supply the deleted information if requested by the board staff. The deleted information may be filed with a request for confidentiality, pursuant to 199 Iowa Administrative Code rule 1.9(22).
	 19.13(6) Written notice of risks. The utility must notify its large volume users as defined in 19.14(1) contracting for transportation service in writing that unless the customer buys system supply reserve service from the utility, the utility is not obligated to supply gas to the customer. The notice must also advise the large volume user of the nature of any identifiable penalties, any administrative or reconnection costs associated with purchasing available firm or interruptible gas, and how any available gas would be priced by the utility. The notice may be provided through a contract provision or separate written instrument. The large volume user must acknowledge in writing that it has been made aware of the risks and accepts the risks.
