(1) The utility must demonstrate and document how it considered input from advisory group members in the development of its IRP and two-year progress report. Examples of how the utility may incorporate advisory group input include using modeling scenarios, sensitivities, and assumptions advisory group members proposed and using data and information supplied by advisory group members as inputs to plan development. As part of this process and consistent with WAC 480-100-625(5), the utility must communicate to advisory group members about whether and how the utility used their input in its analysis and decision making, including explanations for why the utility did not use an advisory group member's input.

(2) The utility must make available completed presentation materials for each advisory group meeting at least three business days prior to the meeting. The utility may update materials as needed.

(3) The utility must make all its data inputs and files used to develop its IRP available to the commission in native file format, per RCW 19.280.030 (10)(a) and (b), and in an easily accessible format. The utility may make confidential information available by providing it to the commission pursuant to WAC 480-07-160. The utility should minimize its designation of information in the IRP as confidential. Nonconfidential contents of the IRP, two-year progress report, and supporting documentation as well as nonconfidential data inputs and files must be available for advisory group member review in an easily accessible format upon request. Nothing in this subsection limits the protection of records containing commercial information under RCW 80.04.095.
