WATER SYSTEM MANAGEMENT PLAN OCTOBER 2024 / CAROLLO <br />CITY OF PLEASANTON WATER SYSTEM MANAGEMENT PLAN 19 <br /> OM-3 Water System Operations Manual: The City should update its Water System Operations <br />Manual to reflect current conditions and practices. <br />8.1.5 SCADA Master Plan <br />The following projects and programs were developed as part of the SCADA Master Plan. Additional details <br />for all these recommendations are included in the SCADA Master Plan located in Appendix F. <br /> SP-4 SCADA Standards Development: The City currently does not have an official set of <br />comprehensive SCADA standards. Development of SCADA standards is a vital component for any <br />SCADA system. The City should formalize standards that can be provided to internal or external <br />resources. SCADA standards encompass items such as instrumentation standards, PLC/OITs, PLC <br />cabinet hardware and layouts, SCADA software, SCADA hardware, and SCADA programming. <br /> SP-5 SCADA Preventive Maintenance Program: The City should develop a formalized preventative <br />maintenance program for critical electrical, instrumentation, and controls assets, and re-evaluate <br />third-party maintenance contracts to include these activities. <br /> SP-6 Backup Core Server Relocation: The City should diversify and relocate its core SCADA server to <br />the virtual environment and eliminate the risk of the current server hardware access locations. <br /> SP-7 Remote Access Improvements: The City should implement remote SCADA access solutions to <br />offer granular access control, enabling customized control per protocol, per user activity, and per seat, <br />with continuous monitoring and enforcement for the duration of every session. <br /> SP-8 Operational Technology (OT) System Monitoring Implementation: The City should investigate <br />implementing an OT focused cybersecurity monitoring solution that provides OT-specific asset visibility <br />and inventory, vulnerability management, threat detection and investigation tools. The implementation <br />of such a monitoring tool would considerably improve overall monitoring coverage and additionally <br />assist the City in being compliant with new EPA cybersecurity requirements released in March of 2023. <br />8.1.6 O&M Recommendations Summary <br />The recommendations included in Section 8.1 are summarized in Table 7 <br />Page 450 of 658
