Intervention, among other things, entitles a party to present sworn evidence at hearing and to cross-examine other parties' witnesses. Intervention is not required for you to appear at the hearing and provide public comment, to file written comments in the docket for the case, or to receive emailed notice of each filing made in the case by following the docket. Information about what intervention means, including an explanation of the rights and responsibilities of an intervenor, is available on the Commission's website (www.azcc.gov) by clicking on "Divisions" and then "Hearing" and then "Intervene in a Case."

Your request must be filed or eFiled no later than July 20, 2026. Instructions and restrictions for eFiling are available on the Commission's website at http://azcc.gov/hearing/efiling .

A short statement explaining: a. Your interest in the proceeding (e.g., a customer of the regulated company involved, a property owner in an area to be affected by the case, etc.), b. How you will be directly and substantially affected by the outcome of the case, and c. Why your intervention will not unduly broaden the issues in the case; 4.
