Public Input Process 13 ===== PAGE 3 ===== ### A. POLICY STATEMENT Victorville Municipal Utility Services' (VMUS) overarching goal is to provide safe, reliable, and economic electric service to its service territories. In order to meet this goal, Victorville Municipal Utility Services constructs, maintains, and operates its electrical lines and equipment in a manner that minimizes the risk of catastrophic wildfire posed by its electrical lines and equipment. ### B. PURPOSE OF THE WILDFIRE MITIGATION PLAN Victorville Municipal Utility Services entire electric supply system is located underground in conduit and vaults. Historically, underground electric lines have not been associated with catastrophic wildfires. The undergrounding of electric lines serves as an effective mitigation measure to reduce the potential of powerline ignited wildfires. Based on a review of local conditions and historical fires, VMUS has determined that its electrical lines and equipment do not pose a significant risk of catastrophic wildfire. Despite this low risk, VMUS takes appropriate actions to help its region prevent and respond to the increasing risk of devastating wildfires. In its role as a public agency, VMUS closely coordinates with other local safety and emergency officials to help protect against fires and respond to emergencies. In its role as a utility, VMUS follows all applicable design, construction, operation, and maintenance requirements that reduce safety risks associated with its system. This Wildfire Mitigation Plan describes the safety-related measures that VMUS follows to reduce its risk of causing wildfires. ### C. CONTEXT-SETTING INFORMATION Victorville Municipal Utility Services is only a distributor and does not own or operate any generating plants. The service area for Victorville Municipal Utility Services only includes the Southern California Logistics Airport (SCLA) and the Foxborough Industrial Park, less than 60 customers combined. VMUS only serves commercial and industrial customers. Southern California Edison serves all of the residents of the City of Victorville and any commercial / industrial customer not located within the VMUS territory.

===== PAGE 8 ===== ## Ⅱ ## OBJECTIVES OF THE WILDFIRE MITIGATION PLAN The primary goal of this Wildfire Mitigation Plan is to describe VMUS' existing programs, practices, and measures that effectively reduce the probability that VMUS' electric supply system could be the origin or contributing source for the ignition of a wildfire. To support this goal, VMUS regularly evaluates the prudent and cost-effective improvements to its physical assets, operations, and training that can help reduce the risk of equipment-related fires. I ne secondary goal of this Wildfire Mitigation Plan is to improve the resiliency of the electric grid. As part of the development of this plan, VMUS assesses new industry practices and technologies that will reduce the likelihood of an interruption (frequency) in service and improve the restoration (duration) of service. ===== PAGE 9 =====

ROLES AND RESPONSIBILITIES

A. UTILITY GOVERNANCE STRUCTURE

VMUS Wildfire Mitigation Plan June 21, 2022 ===== PAGE 10 ===== The City of Victorville is a general law city that operates under a Council-Manager form of government. VMUS is governed by a five-member City Council. The council appoints the City Manager, who oversees the daily operations of the City. ### B. WILDFIRE PREVENTION VMUS staff is responsible for electric facility design, maintenance, and inspection, including vegetation management. Although VMUS' electrical distribution system is 100% underground, VMUS follows best practices to prevent ignition of wildfires from its equipment. These items include: VMUS performs routine maintenance of all distribution facilities. VMUS adheres to a seasonal weed abatement and vegetation management schedule to maintain at-risk sites. VMUS maintains GO95, GO165, and GO174 standard clearances as part of regular maintenance cycles. VMUS abides by the National Electric Safety Code (NESC) Rule 012 and Rule 218 standards to abate trees, shrubs, weeds, and grass at all VMUS facilities. - Electric system operates in a manner that will minimize potential wildfire risks. - Take all reasonable and practicable actions to minimize the risk of a catastrophic wildfire caused by VMUS electric facilities. Coordinate with federal, state, and local fire management personnel as necessary or appropriate to implement VMUS' Wildfire Mitigation Plan. - Immediately report fires to local fire departments, VMUS administration, and other City Officials, pursuant to existing VMUS practices and the requirements of this Wildfire Mitigation Plan. Coordinate with City Emergency Operations Center to disseminate safety warnings, emergency public information, and evacuation notices to local businesses. VMUS adheres to City of Victorville personnel code 2.36 for Employee Disaster Notification and Reporting. - Take corrective action when the staff witnesses or is notified that fire protection measures have not been properly installed or maintained. Comply with relevant federal, state, and industry standard requirements, including the industry standards established by the California Public Utilities Commission (CPUC). ### C. WILDFIRE RESPONSE AND RECOVERY VMUS field staff utilize hard line telephones, cellular telephones, and portable radios to communicate with internal and external stakeholders during an outage or emergency. VMUS' Outage Management System auto generates notifications to field and administrative staff. The City of Victorville maintains a two-way UHF band radios for communications enhanced by two DMR repeaters to extend the coverage area. The City radios can have up to 1,024 channels; of which twenty are currently programmed channels (eleven use repeaters and nine are simplex). The City of Victorville owns one Iridium satellite phone that is issued to the City's Emergency Management Coordinator or his designee during an emergency. VMUS, along with other key City personnel, have access to a Government Emergency Telecommunications Services (GETS) card and PIN provided by Homeland Security to allow for the capability to respond to National Security and Emergency Preparedness (NS/EP) events. Using the Wireless Priority Services (WPS) with GETS can increase the probability of a call completion in both wireless and wireline networks. ===== PAGE 11 ===== In addition to the City of Victorville Fire Department, Mission Fire Rescue (Mission) services the Southern California Logistics Airport. VMUS and airport staff are able to communicate with Mission Fire Rescue through 400-megahertz radios or by calling their station directly. Additionally, the control tower has a direct line to Mission's fire station, which rings throughout the station and opens the bay doors alerting them of an emergency. CONFIRE provides dispatch services for the City of Victorville Fire Department and Mission. They have the capability of patching in Apple Valley Fire Protection District, CAL FIRE, and contacting several other agencies such as Southwest Gas, Southern California Edison, AMR and other local agencies to assist in an emergency. CONFIRE also functions as the operational area dispatch for the County of San Bernardino, and can coordinate mutual aid as needed. At the county level, a San Bernardino County Emergency Operations Center (EOC) talk group is programmed into an 800-megahertz frequency band radio and is used to communicate with EOCs within San Bernardino County during a disaster or emergency. The City of Victorville contracts with San Bernardino County Sheriffs. They too utilize 800-megahertz frequency band radios to communicate and have the capability to patch in California Highway Patrol, CAL FIRE, and other county resources to assist during emergencies. City of Victorville also maintains a reporting hotline to notify the city for code violations, hazards, safety concerns, and overgrown landscaping and weeds. Additionally, the City allows its constituency to report any code violations on line via the City's website. VMUS adheres to California Public Utility Commission GO 95, 165, and 174 for all system infrastructure inspection, maintenance, and reporting. ### D. STANDARDIZED EMERGENCY MANAGEMENT SYSTEM As a local governmental agency3, VMUS has planning, communication, and coordination obligations pursuant to the California Office of Emergency Services' Standardized Emergency Management System ("SEMS") Regulations4, adopted in accordance with Government Code section 8607. The SEMS Regulations specify roles, responsibilities, and structures of communications at five different levels: field response, local government, operational area, regional, and state.5 Pursuant to this structure, VMUS annually coordinates and communicates with the relevant safety agencies as well as other relevant local and state agencies. When activated, VMUS serves as the Utilities Unit Leader under the Operations Section Chief as part of the City Victorville Emergency Operations Center. In the event that the incident centered on VMUS facilities, VMUS would serve as the Operations Section Chief. Under the SEMS structure, a significant amount of preparation is done through advanced planning at the ===== PAGE 12 ===== county level, including the coordination of effort of public, private, and nonprofit organizations. San Bernardino County serves as the Operational Area and is guided by the California Office of Emergency Services Southern Region. The Operational Area includes local and regional organizations that bring relevant expertise to the wildfire prevention and recovery planning process. These participants are listed below:

Pursuant to the SEMS structure, VMUS participates in annual training exercises. Training exercises include workshops and tabletop exercises. A sample of topics covered include earthquake safety, disaster response & management, and NIMS/SEMS/ICS compliance. ===== PAGE 13 ===== V. WILDFIRE RISKS AND DRIVERS ASSOCIATED WITH DESIGN, CONSTRUCTION, OPERATION, AND MAINTENANCE ### A. PARTICULAR RISKS AND RISK DRIVERS ASSOCIATED WITH TOPOGRAPHIC AND CLIMATOLOGICAL RISK FACTORS Due to VMUS's distribution system being 100% underground, the primary risk drivers for wildfire within VMUS's service territory are the following: Earthquake • Flooding ### B. ENTERPRISEWIDE SAFETY RISKS Earthquake profile - There are two major faults/fault zones that directly affect VMUS. They are the San Andreas Fault and the Helendale Fault zones. The City of Victorville sits in the middle of both faults. The San Andreas Fault is the longest fault in California and is known to cause powerful earthquakes, as big as a magnitude eight (8.0).6 This fault is located south-west of Victorville. The Helendale Fault creates smaller, yet more frequent earthquakes and is located northeast of the city. The most recent major earthquake to affect the City of Victorville was the Ridgecrest earthquake, approximately 82 miles north of the city. This earthquake struck July 5, 2019 and had a magnitude of 7.1. Large earthquakes occurring in many parts of the Southern California region could affect the City of Victorville. However, the degree to which the earthquakes are felt, and the damages associated with them may vary. At risk from earthquake damage are critical facilities, buildings, bridges, highways and roads; hazardous materials facilities; sewer, water, natural gas pipelines; earth dams; petroleum pipelines; and private property located in the city. The relative or secondary earthquake hazards, which are liquefaction, ground shaking, amplification, and earthquake-induced landslides, can be just as devastating as the earthquake. Flooding profile - There are four types flooding conditions that exist within the City of Victorville area; flooding in defined watercourses; ponding; sheet flow; and dam inundation. Flooding within defined watercourses occurs within drainage channels and immediately adjacent floodplains. Ponding occurs when water flow is obstructed due to manmade obstacles and other roadways, where they cross-defined watercourses. Sheet flow occurs when capacities of defined watercourses are exceeded and water flows over broad areas. Known flood-prone areas noted in the General Plan as well as recorded in city maintenance files, include:

### V. ## WILDFIRE PREVENTATIVE STRATEGIES ### A. LOW FIRE THREAT DISTRICT The CPUC's Fire Threat Map includes three Tiers/Levels of fire threat risk. Tier 1 consists of areas that have the lowest hazards and risks, tier 2 consists of areas where there is an elevated risk for destructive electric line-ignited wildfires, and tier 3 consists of areas where there is an extreme risk for destructive electric line-ignited wildfires. The City of Victorville is located in Tier 1. Despite the city's classification of Tier 1, VMUS is cognoscente of the potential dangers; and therefore, implements practices that go above the required industry standards as described below. Additionally, VMUS customers are unlikely to be directly impacted by an investor-owned utility (IOU) public safety power shutoff (PSPS) event because VMUS is not on the Southern California Edison's PSPS circuit. ### B. DESIGN AND CONSTRUCTION STANDARDS VMUS' electric facilities are designed and constructed to meet or exceed the relevant federal, state, or industry standard. VMUS treats CPUC General Orders (GO) 95 and 128 as a key industry standard for design and construction standards for underground electrical facilities. VMUS meets or exceeds all standards in GO 95 and 128. Additionally, VMUS monitors and follows, as appropriate, the National Electric Safety Code. ### C. VEGETATION MANAGEMENT VMUS meets or exceeds the minimum industry standard vegetation management practices. For distribution level facilities, VMUS meets: (1) Public Resources Code section 4292; (2) Public Resources Code section 4293; (3) CPUC GO 95, 128, 165, and 174. VMUS' annual budget includes funding for weed abatement to ensure compliance with the standard vegetation management practices. VMUS' system is almost entirely underground; thus the system has minimal vegetation risks. ===== PAGE 16 ===== ### D. INSPECTIONS VMUS meets or exceeds the minimum inspection requirements provided in CPUC GO 165 and 174. As described above, VMUS currently does not have any overhead power lines located within or near a Tier 2 or Tier 3 Fire Threat District; however, VMUS staff uses their knowledge of the specific environmental and geographical conditions of VMUS' service territory to determine if any particular areas require more frequent inspections. If VMUS staff discovers a facility in need of repair that is owned by an entity other than VMUS, VMUS will issue a notice to repair to the facility owner and work to ensure that necessary repairs are completed promptly. ### E. RECLOSING POLICY VMUS' electrical system is primarily underground and has no automatic re-closures in service. In a relayed event, re-closures will be handled on a case-by-case basis after circuit and equipment inspections have been performed. VMUS does not change substation relay settings. ### F. DE-ENERGIZATION VMUS has the authority to preemptively shut off power due to fire-threat conditions; however, this option will only be used in extraordinary circumstances. Due to the minimal risk of VMUS' electrical supply facilities causing a power-line ignited wildfire, VMUS is not adopting specific protocols for de-energizing any portions of its electric distribution system. VMUS will re-evaluate this determination in future updates to this Wildfire Mitigation Plan. ### VI. RESTORATION OF SERVICE VMUS' electric distribution system is completely underground. However, we are interconnected with SCE's transmission and distribution systems, much of which is overhead and exposed to wind, rain and lightning. This is our primary source of vulnerability to potential electrical service interruptions during rain and windstorms such as the ones that can be precipitated by El Niño. Our underground electric distribution system is designed, and has been constructed, with redundant sources of feed. These do not guarantee the elimination of outages but can facilitate service restoration and reduce the duration of such outages. Preparation in advance of predicted storms: Since, as discussed in the introduction, our primary trouble source during storms is outages on SCE's transmission and distribution lines, many of which are overhead, we will patrol, to the extent practical, SCE's primary interconnect lines for any potential trouble spots or vulnerabilities. We will also double check the loading conditions of our underground lines to satisfy ourselves that alternate sources have the capacity to serve the electric load (customers) in the event that it is necessary. Our underground system will be patrolled in advance of storms for any open trenches or excavations at construction sites to minimize water intrusion into the underground system. Although the underground system is designed to operate under such conditions, small pinholes in splices or cable can cause problems, including possible electrical shorts/faults that can interrupt service to customers. Likewise, after the storm, each underground vault, manhole or other structure will be inspected for water intrusion and pumped, when necessary, in accordance proper utility practice and environmental guidelines. ===== PAGE 17 ===== All vehicular equipment, tools, and appurtenances will be thoroughly inspected for proper operation. All operating personnel will be placed on standby in the event of weather related problems. The VMUS operations and admin staff will be prepared for handling of trouble calls from customers and dispatching to field personnel. Call Center support includes: Outage Management System (OMS) Field Dispatching • Coordinating with VMUS' Qualified Emergency Electrical contractors Customer Callbacks Response Prioritization: First Priority: Response to imminent threats to life and/or public property Second Priority: Removals of immediate hazards (fallen trees, power poles, etc.) Third Priority: Clearing of arterial roadways Fourth Priority: Maintenance of traffic control/closures to prevent potential accidents Fifth Priority (Post Storm Activity): Follow-up work such as addressing storm-related potholes and residual clean-up of all streets that have remained in a "passable and drivable" state Referral Protocol: Flooding of structures on private property- Businesses will be advised to call 911 for Fire Department assistance Facilities associated with private utilities will be referred to appropriate company All storm related issues involving streets, curbs and gutters, sidewalks, trees in the right of way, catch basins, and miscellaneous drainage facilities will be referred to the City's Maintenance and Operations Division. During EOC activation period, all routine maintenance programs and requests will be suspended and deferred. ### VII. PLAN EVALUATION ### A. METRICS AND ASSUMPTIONS FOR MEASURING PLAN PERFORMANCE VMUS will track the following metric to measure the performance of this Wildfire Mitigation Plan: (1) Number of fire ignitions caused by utility equipment. ===== PAGE 18 ===== ### 1. Metric 1: FIRE IGNITIONS For purposes of this metric, a fire ignition is defined as follows: - VMUS facility was associated with the fire; The fire was self-propagating and of a material other than electrical and/or communication facilities; - The resulting fire traveled greater than one linear meter from the ignition point; and - VMUS has knowledge that the fire occurred. In future Wildfire Mitigation Plans, VMUS will provide the number of fires that occurred that were less than one (1) acre in size within VMUS' service territory. Any fires greater than one acre will be individually described. ### B. IMPACT OF METRICS ON PLAN In the initial years, VMUS anticipates that there will be relatively limited data gathered through the metric. However, as the data collection history becomes more robust, VMUS will be able to identify areas of its operations and service territory that are disproportionately impacted. VMUS will then evaluate potential improvements to the plan. ### C. MONITORING AND AUDITING THE PLAN This Wildfire Mitigation Plan will be presented to the Victorville City Council. VMUS staff will review the plan on an annual basis and bring updates to the Council as needed. ### D. IDENTIFYING AND CORRECTING DEFICIENCIES IN THE PLAN Based on the recommendations of the Victorville Fire Department and the Victorville City Council, VMUS will correct any identified deficiencies. ### E. MONITORING THE EFFECTIVENESS OF INSPECTIONS VMUS' Utility Maintenance Management System (UMMS) is used to collect all data subject to GO165. Quarterly inspection and maintenance reports are generated for all electric distribution facilities. Maintenance history for each piece of equipment is archived in the UMMS. Additionally, VMUS' substation inspection and maintenance program complies with GO174 guidelines as well as manufacturer specifications, standards, and recommendations. VMUS performs regular inspections of all substation components including recording and analysis of all alarms, fluid levels, meters, and Load Tap Changer settings. Although VMUS does not fall under the jurisdiction of the California Public Utilities Commission (CPUC), VMUS would cooperated with the CPUC's Utilities Safety and Reliability Branch and their requests for periodic audits. ### VIII. Public & Professional Feedback ### A. CMUA – Wildfire Preparedness, Response and Recovery Working Group ===== PAGE 19 ===== The California Municipal Utilities Association (CMUA) will be holding a special meeting of its Wildfire Preparedness, Response, and Recovery Working Group this fall, which will be focused on risk drivers for powerline caused catastrophic wildfires and innovative mitigation options. CMUA plans to invite a broad range of utility staff, state agency staff (including the WSAB), industry experts, and academics to participate in this discussion. As part of this meeting, the working group will discuss unidentified wildfire risk drivers and mitigation measures that could address these risks. Based on the input provided during this meeting, CMUA will produce a publicly available, post-meeting report that summarizes the group's conclusions and recommendations. VMUS' staff will participate in CMUA's meeting and will discuss any changes that VMUS has made to its operations in response to the conclusions and recommendations of the working group in a future WMP. ### B. Public Input Process VMUS is governed by the Victorville City Council. This plan was brought forth to the City Council and members of the public on June 21, 2022. Due to the adoption of the plan not requiring a notice of public hearing or any special noticing requirements, the noticing of the plan followed the City's standards per the Brown Act. The agenda was posted a week in advance and public comment is a section of the agenda where members of the public can speak freely on any item on the agenda. Members of the public are given three minutes to speak on their items; at the time of the plan's adoption, there were no speakers. The next adoption of the plan by the Victorville City Council will be in 2024. At this time, VMUS will engage the public via a comment box on the City's website with a draft plan, seeking public review and suggestions; any suggestions provided will be discussed and incorporated into the plan as needed. Staff will advise customers via email of the availability to review the plan and provide feedback.1 Appendix I: 2021 Informational Response has been removed as the information has been incorporated into the overall plan, per the California Wildfire Safety Advisory Board.
