The Procedural Order was issued in light of Arizona-American's failure to provide proper notice of the rate case proceeding to a large number of its Agua Fria Water District customers. The scheduled first day of the hearing, held on Wednesday afternoon, August 17, 2011, was limited to public comment only.

On Monday, August 22, 2011, over 850 concerned individuals attended the first of the two scheduled public comment meetings on AAWC's Application.  Ratepayers voiced their opinions to three of the five sitting ACC Commissioners during the meeting held on Monday, August 22, 2011, at Sonoran Plaza in Surprise, Arizona.

During the procedural conference held on Monday, September 19, 2011, the parties to the case discussed possible dates for an evidentiary hearing and the filing of written testimony from new intervenors to the case who requested intervention by the August 24, 2011 filing deadline.  

On Friday, September 23, 2011, the ALJ assigned to the case issued a Procedural Order(link is external) scheduling the evidentiary hearing on the matter for 10:00 a.m. on Monday, December 5, 2011.  Additional hearing dates have been scheduled for December 6, 7, 8, 9, 12, 15, and 16, 2011.

The evidentiary hearing on the Company's rate request began as scheduled on Monday, December 5, 2011, at 1200 W. Washington in Phoenix.  Opening statements were heard from the attorney's representing the parties to the case after AAWC customers were given the opportunity to make public comment. 

On Wednesday, December 7, 2011, the parties to the case informed the ALJ assigned to hear AAWC's rate request that they expected to reach a global settlement agreement that would be filed on Friday, December 9, 2011.  The ALJ granted the parties' request to recess the hearing in order to provide time for the parties to the case to finalize a letter of intent on a proposed settlement agreement.

On Thursday, December 8, 2011, the parties to the case filed a letter of intent(link is external) with the ACC.

On Thursday, December 15, 2011, the parties to the case filed a proposed settlement agreement (link is external)("Settlement Agreement") with the ACC.  On that same day, RUCO Director Jodi A. Jerich filed direct testimony(link is external) in support of the Settlement Agreement.

The evidentiary hearing on the Settlement Agreement concluded on Friday, December 16, 2011.  Final arguments were given orally by the attorneys representing the parties to the case at the end of the hearing in lieu of filing closing legal briefs.

After weighing the evidence presented during the proceeding, including comments from concerned ratepayers, the ALJ assigned to the case issued a Recommended Opinion and Order(link is external) ("ROO") on Tuesday, April 3, 2012 that adopts the proposed settlement agreement.

On Thursday, April 12, 2012 the signatory parties to the proposed settlement agreement filed a response(link is external) to the ROO which concurred with the ALJ's conclusions and respectfully requested that the Commission adopt the ROO.
