Arizona’s Future
• Reconsultation to begin by Dec. 31, 2020
• States will lead as they did in the 2007 Interim Guidelines
• Arizona participants likely to expand
• Basin states yet to discuss scope of new guidelines
• 2007 guidelines + DCP – Lessons learned
• Expect reductions in Arizona to be unmitigated
