facilities to export natural gas to an interstate pipeline; (2) by establishing a method for calculating
monthly access fees; and (3) by clarifying that the Interruptible Distribution Transportation Service
(“Schedule T-3”) tariff rate will apply to the transport of RNG using the Company’s distribution
system to any interconnection point with Northwest Pipeline. The Company’s Application
included several supporting exhibits and requested an effective date of July 1, 2023. In Order No.
