IPAG Background

Regional Recharge Plan (1998)

AWBA Facilities Plan for TAMA (1998)

Ongoing examination• Recharge capacity & sites

» Kai-Avra proposal (2000)

• Subcontract firming • Recovery

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

Analysis

Re-examination of the 1998 Regional Recharge Plan

• Much of the report remains valid and useful

• Partially outdated due to additional facilities and other factors

Updated analysis• More comprehensive exploration of physical

& financial variables

• Emphasis on AWBA activities

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

Analytic Tool

• DEMAND by sector & provider

• USF & GSF capacities & fees

• AWBA funding & storage

• STORAGE by facility, storer & year

“Baseline” Assumptions• Cost of water: CAP advisory rates through 2007, 3% growth thereafter

• Ad valorem tax: $1.6 million base, 3% annual growth

• Facility charge: flat $12, based on average cost at TAMA USFs and 2% GSF

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

CAP Firming

• 200,000+ AF shortfall (30% below target)

• Shortfall reflects revenue constraints and cost of credits• Will likely result in future groundwater mining

The AWBA’s firming target for the Tucson AMA will not be met with projected revenue

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

Firming Options

Bridging the firming gap {options under consideration}

– Lower the cost of credits• Continue to lower water costs

• Seek low-cost energy

• Continue to lower storage costs at USFs • Spread fixed costs by utilizing available capacity

• Increase utilization of TAMA GSFs• Invest in infrastructure to GSFs willing to pay $21/AF• Use Withdrawal Fee money to buy-down the $21• Lower the AWBA GSF price for the Tucson AMA

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

Firming Options

Bridging the firming gap {options under consideration}

– Restructure existing TAMA revenue sources

• Extend ad valorem revenue stream• Use Withdrawal Fee money for firming

– Other

It is likely that a combination of solutions will be required

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

• Lowering the cost of credits through buy-down of the $21/AF80% USF; 20% GSF with $4/AF buy-down

“Baseline” 98% USF

Firming Options Hypothetical Example

30% USF; 70% GSF with $4/AF buy-down

AWBA Board Meeting, March 20, 2002Tucson AMA Institutional and Policy Advisory Group (IPAG)

• Encourage & participate in dialog with CAWCD, AWBA, ADWR, et al.

• Further identify TAMA subcontractors’ recovery needs

• Explore the recovery implications of interstate storage

Recovery

There is strong interest in where water is stored and how it will be recovered

Recovery planning activities

Next Steps

Continue to refine analysis• Develop recommendations
