AriSEIA Files 2nd Round of Comments on the ACC Line Siting Rules

Read the Filing

AriSEIA has filed comments with the Arizona Corporation Commission on the latest draft of the proposed Power Plant and Transmission Line Siting Committee rules and the accompanying Preliminary Economic Impact Statement. While the revised draft addresses several stakeholder concerns, important improvements are still needed to ensure the Line Siting process is transparent, fair, and accessible for all participants.

Our comments recommend practical procedural improvements, including establishing reasonable time limits for Certificates of Environmental Compatibility, providing more advance notice for Committee meetings, creating clear procedures for jurisdictional determinations, improving public access to hearing transcripts, allowing limited discovery, expanding opportunities for remote participation, and ensuring the Commission reviews every Certificate of Environmental Compatibility before it becomes effective. We also encourage a more robust evaluation of how the proposed rules will affect transparency, public participation, and the ability of stakeholders to meaningfully participate in these proceedings.
​
Modernizing Arizona's Line Siting rules is an important opportunity to improve the process for developers, landowners, local governments, and the public. AriSEIA appreciates the work that has gone into the revised draft and looks forward to continuing to work with the Commission to develop rules that provide greater transparency, procedural fairness, and regulatory certainty while supporting responsible energy infrastructure development across Arizona.
