(a) Integrated resource plans (IRP) and alternatives. Each Western customer must address its power resource needs in an IRP prepared and submitted to Western as described in this subpart. Alternatively, Western customers may submit a small customer plan, minimum investment report or EE/RE report as provided in this subpart.

(b) Rural Utility Service and state utility commission reports. For customers subject to IRP filings or other electrical resource use reports from the Rural Utilities Service or a state utility commission, nothing in this part requires a customer to take any action inconsistent with those requirements.
