C&W Ref. 256618 <br />for power systems and SCADA/PLC equipment. Our findings, along with recommended <br />improvements, will be detailed in the final report. The report will also incorporate photographs <br />and data collected during grounding tests performed by a qualified electrical contractor. <br />Our field investigation will focus on evaluating lightning and surge protection measures for <br />electrical power systems, emergency power infrastructure, PLC field panels, and SCADA <br />systems—including RTUs and radio antennas. <br />To support this effort, we will coordinate with electrical contractors to obtain pricing for <br />grounding tests. Formal proposals will be submitted to IRCDUS staff for procurement <br />consideration. <br />Upon contractor selection, we will participate in field testing activities to oversee and document <br />the grounding evaluation process. We anticipate a three-day field schedule with the contractor <br />to complete these assessments. <br />Task 3: Wellfield Emergency Standy Facility Evaluation: <br />We will perform an assessment to evaluate emergency power options for existing wells and <br />develop an alternatives analysis to provide backup power coverage for all well sites associated <br />with the Oslo Water Treatment Plant (WTP). The proposed alternatives will include: <br />1. Installation of a centralized emergency generator at the Intergenerational Center to <br />serve wells S-5, S-6, and S-7. <br />2. Standalone generators installed at wells S-5, S-6, and S-7. <br />3. An additional generator at the Oslo WTP with conduit and conductors routed from the <br />WTP to each well site. As part of this option, consideration will be given to removing the <br />existing standalone generator at well S -4R to reduce ongoing maintenance costs. <br />A parallel alternatives analysis will be conducted to provide emergency backup power for the <br />Hobart WTP well sites. This analysis will examine: <br />1. A centralized generator serving wells N-7, N-9, and future well sites. <br />2. Standalone generators installed at wells N-7 and N-9. <br />3. Extension of power service from the WTP to back up the separate FPL electrical <br />service. <br />We will quantify the limitations of the existing emergency generators at both Oslo and Hobart <br />WTPs in supporting Option 3, and where needed, recommend system enhancements to <br />improve resiliency. <br />135 <br />
