ITEIVI #1 — DISCUSSION REGARDING THE GROUNDWATER PRODUCTION
SUSTAINABILITY EVALUATION �
Chair Milkey opened the discussion on this matter. There was discussion regarding the
definition of sustainable, aquifer recharge and water level declines. The discussion included if
the definition of sustainable should be based upon a recharge or zero water level declines. Mr.
Abraham gave an overview of an updated table from the 2007 groundwater evaluation report.
He explained the current condition as compared to the projected water levels from the report.
The aquifer is responding positively as a result of the development of renewable water. Water
level declines are significantly less than the predicted�levels. Staff recommended an additional �
� amount of time, perhaps 2 to 5 years, at the current lower pumping rates is necessary to
further evaluate the aquifer condition. Regarding the use of the word sustainable, Mr. Saletta �
suggested using another term such �as target groundwater production rate.
No formal action was taken or required.
ITEIVI #2 — DISCUSSION REGARDING THE FORMAT OF THE GROUNDWATER LEVEL
AND AQUIFER METRICS DATA
Chair Milkey requested staff format the data so there is a year-by-year groundwater level
comparison when presenting the aquifer metrics to the Subcommittee and the Commission.
Mr. Saletta indicated they can present the data in that format after the report is completed and
it will be presented to the Commission in October.
No formal action was taken or required.

ITEM #3 — DISCUSSION AND UPDATE REGARDING THE CAP RECHARGE AND
RECOVERY DELIVERY SYSTEM.
Mr. Saletta explained water stored at Kai Farms Groundwater Savings Facility will be used for
annual recovery for 2016 instead of Lower Santa Cruz Replenishment Project. This will
increase Oro Valley's storage balance in Lower Santa Cruz. There was discussion regarding
the annual amounts of storage at the various facilities.
No formal a�ction was taken or required. ,
ITEM #4— DISCUSSION AND UPDATE REGARDING THE CAP RECHARGE AND
RECOVERY DELIVERY SYSTEM. �
Mr. Saletta gave an update regarding the possible partnership with Metro, Marana and Flowing
Wells. Staff is reviewing the first draft of an intergovernmental agreement. It is anticipated that
the agreement would go to Council by the end of 2016. Metro is moving forward with land
acquisition and easements. Mr. Abraham reported water quality data has been analyzed and
reviewed by Carollo Engineers. Carollo has prepared a first draft of a report for Oro Valley
Water Utility with preliminary results indicating water quality from the Lower Santa Cruz wells
meet all standards and blending of that water into our system is feasible. The project is
proposed to be on line in FY 2024.
No formal action was taken or required.
