It advised the EUB that it was excluding the “Salt Cavern” assets from its applied-for rate base. Its justification for doing so was that while those assets had historically been included, they were no longer being used for transmission service, and would not be used in the foreseeable future. The Alberta Utilities Commission (AUC) advised ATCO that ATCO could not exclude the assets from the application absent an application by ATCO (and AUC approval) under s. 26 of the Gas Utilities Act, R.S.A. 2000, c.

ATCO argued that since it was not selling the property or otherwise disposing of it, but was simply moving it out of rate base, approval under s. 26 should not be required.
