TITLE:
Consideration and Approval of Grant Agreement: Approve the Grant Agreement with the Department of Emergency Management and Military Affairs (DEMA) for the Rio de Flag Water Reclamation Plant Backup Generators.
STAFF RECOMMENDED ACTION:
- Approve the Grant Agreement with DEMA for the Hazard Mitigation Grant Program (HMGP) for Rio de Flag Water Reclamation Plant Backup Generators (HMGP DR-4524-16-11R) for $450,000.00 (90% State Share), with a $50,000.00 (10% local match) requirement; and
- Authorize the City Manager to execute all necessary documents.

Financial Impact:
The Grant Agreement is for a HMGP for Rio de Flag Water Reclamation Plant Backup Generators (HMGP DR-4524-16-11R) for a total award amount of $450,000.00 with a $50,000 local match requirement. The total budget for this grant funded project is $455,600 in account number 410-08-375-3529-3-4405. This is Pre-Construction and Design Phase #1 of a 4 phase grant award. Once the City has demonstrated completion of Phase #1 DEMA will release the remaining funds to construct ($5,190,000.00).

Previous Council Decision or Community Discussion:
No.
Options and Alternatives to Recommended Action:
Options and Alternatives:
1. Accept the Grant Agreement which will provide funding to complete the engineering, design and geotechnical assessment needed to construct backup power at the RDF WRP
2. Do not accept the Grant Agreement and the DEMA funds will be returned. Alternative sources of funding will be needed to be identified to complete this project.

Background and History:
Background/History:
RDFWRP has two primary power feeds running from APS into the facility. This allows for redundancy in case of power failure in the primary feed. These feeds are operated by APS on a manual switchgear; therefore, if power is lost, the facility must wait for APS to switch to the other feed. If both feeds go offline, then the facility is out of commission. Any significant loss of voltage into the plant could lead to the death of integral microorganisms and equipment failure at RDFWRP. Flow is then redirected to WCHWRP, overwhelming their facility and potentially putting operations out of compliance and threatening environmental and public health. The local match portion will be coming from the Prop 441 bond which is underfunded. With this grant, work can be completed with minimal value engineering.
Wildfire is another imminent risk in northern Arizona, potentially impacting power supply from APS. Nearly every year, power supplies were threatened across the state due to fire risk. Flooding, wind, and storms can also threaten power supply. These risks have been exponentially increasing over the past decade.
In order to mitigate these potential hazards, a minimum of four transfer switches and two to three backup generators will be required. Automatic switches will be implemented so RDFWRP can be transferred to backup generators until power is restored. These upgrades ensure adequate voltage is maintained at RDFWRP and that plant operation can continue in the event of a power failure.
