ADVICE 4327-E (U 338-E) -2- October 30, 2020 approved wildfire mitigation plan and recommendations of the most recent safety culture assessment, and a statement of the recommendations of the board of directors safety committee meetings that occurred during the quarter. The advice letter shall also summarize the implementation of the safety committee recommendations from the electrical corporation’s previous advice letter filing. If the division has reason to doubt the veracity of the statements contained in the advice letter filing, it shall perform an audit of the issue of concern. SCE provides the required information as indicated below: (1) Implementation of Wildfire Mitigation Plan On February 7, 2020, SCE submitted its second comprehensive WMP covering the years 2020 through 2022 and building on its 2019 WMP, including successes and lessons learned. After an extensive review process that included discovery, workshops, and comments, the CPUC approved SCE’s 2020-2022 WMP on June 11, 2020.4 In 2020, SCE is tracking 69 specific wildfire-related programs and activities included in its 2020-2022 WMP. As in SCE’s 2019 WMP, the 2020-2022 plan includes wildfire mitigation activities such as infrastructure hardening, vegetation management, detailed inspections and remediations, and situational awareness. SCE’s WMP also emphasizes Public Safety Power Shutoff (PSPS) resilience and community engagement, particularly for under-represented groups and access and functional needs customers. SCE’s 2020-2022 plan increases the use of data, advanced risk analytics and innovative technologies to help the company prioritize the activities with the greatest potential to mitigate wildfire risks and improve public safety. In Attachment A, SCE presents detailed information about the implementation status of meeting WMP 2020 Program Targets for each of these wildfire-related mitigation activities and programs. As referenced in Attachment A, SCE is currently substantially on track or has met the majority of 2020 goals listed in its 2020-2022 WMP. SCE remains cautiously optimistic that it will be able to meet the year-end program targets in most behind-plan activities but notes that the targets for three activities, SH-10 (Tree Attachment Remediations) and SH 12.1 and 12.2 (Distribution Inspection-driven Remediations and Transmission Inspection-driven Remediations) are at risk. COVID-19-related restrictions have had an impact on the implementation plans for a few WMP activities and, in recent months, fires and the associated diversion of crews, poor air quality, and US Forest Service 4 CPUC WMP approval statement available at: https://docs.cpuc.ca.gov/PublishedDocs/Published/G000/M340/K129/340129782.PDF.

ADVICE 4327-E (U 338-E) -3- October 30, 2020 work stoppages as well as heat waves have impeded work in affected areas. Attachment A (Appendix) provides more details on Behind Plan activities including plans to identify and prioritize pending activities during the remainder of the year. (2) Implementation of Most Recent Safety Culture Assessment SCE has not yet undergone a CPUC-led safety culture assessment pursuant to PUC Section 8389(d)(4). Notwithstanding this, safety is the first of SCE’s core values and this is demonstrated through the company’s commitment to creating and maintaining a safe environment for employees, contractors, and the public. SCE continues to improve its safety culture via meetings, trainings, corporate messaging and the incorporation of feedback from all levels of the organization. The Wildfire Safety Division (“WSD”) is currently in the process of developing an annual Safety Culture Assessment Process Proposal with plans to conduct its first assessment for individual electrical corporations in the summer of 2021. SCE looks forward to working with WSD and other interested stakeholders in 2021 to review its safety culture and build upon existing efforts to strengthen it. (3) Recommendations of Safety and Operations Committee The Committee had a single meeting during the third quarter of 2020 (on August 26, 2020). During this meeting, the Committee focused on wildfire and safety issues in the following categories: Wildfire Safety and Employee, Contractor and Public Safety. Each of these areas is separately addressed below. Wildfire Safety Discussions at the third quarter meeting covered an overview of the current fire season and ignition data, the status of the WMP progress to date, asset data management, and the plan to address identified WMP deficiencies as identified by WSD. Regarding the status of the current fire season and the WMP, topics included the impact of sectionalization in reducing customer impacts of the Public Safety Power Shutoff events, ignition trends year-to-date as compared to 2019 ignitions, and the analysis of mitigations in the WMP that may have prevented ignitions. The progress on the WMP and areas where plans are being implemented to meet targets, including on transmission inspections, was also covered. The Committee was also made aware of the stand down of a helicopter contractor due to a fatality outside of SCE’s service area. Management also reported on ongoing asset data management process enhancements. The Committee and management discussed various factors regarding asset data management, including the structure of corporate and

ADVICE 4327-E (U 338-E) -4- October 30, 2020 business unit data governance and identification of risks related to asset data management. A summary of SCE’s responses to Class A deficiencies as identified by WSD and the plan for SCE’s response to Class B deficiencies was provided to the Committee. Management discussed the scope and timing of SCE’s long-term plan for wildfire mitigation in detail, including its alignment with WSD’s maturity model. Employee, Contractor and Public Safety The Committee concentrated on worker and contractor safety at its third quarter meeting, discussing leading indicators for safety performance, worker safety and the contractor safety program. Management reported on SCE’s safety performance including the serious injuries and fatalities and Days Away, Restricted or Transferred (“DART”) rates and performance year-to-date of those factors as compared to 2019. Management and the Committee discussed serious injury leading indicators and potential correlation of serious and/or fatal injuries to the districts targeted for reduction in DARTs. Management also reported on employee safety performance including impacts of teleworking on the DART rate. Management noted that while the DART rate of field workers had declined year-to-date in comparison to 2019, the serious injuries have not decreased. The Committee and management also discussed key drivers of contractor safety performance. Management provided an overview of the contractor safety program, the gating process for prequalification and the role of the business unit, supply management and the safety organization in contractor management. Management also noted the potential impact of independent ratings of contractor safety combined with SCE’s own assessment of performance on the allowed scope of work for such contractors. The Committee and management discussed aspects of the contractor safety program, including various factors that contribute to contractor management and oversight. Committee Recommendations/Management Responses The Committee made the following recommendation(s) and request(s) during its third quarter meeting: 1. The Committee recommended that management benchmark the use of leading indicators and management practices for contractor safety performance and provide a report in a future meeting regarding any variances with current practices.

ADVICE 4327-E (U 338-E) -5- October 30, 2020 2. The Committee asked management to follow up with a deep dive on the Safety Culture Assessment survey results of the districts targeted for further work on reducing DARTs; specifically looking at areas of opportunity for this group, and include similar analysis for locations where safety performance is high. In response to the Committee’s recommendations in prior meetings, management provided the following responses at the third quarter meeting: 1. In addition to the detailed plan on location-specific DART safety action plans provided at the June 26th meeting, management discussed potential correlation of serious and/or fatal injuries to the seven target districts for DART improvement during the report on Safety and Operations Metrics. 2. Management provided an update on the development of the long term plan for wildfire mitigation, during the update on the WMP. An overview of the contractor safety program was provided during the Worker Safety Update Report. In addition, a report on Contractor Management Practices is scheduled to be provided at the October 21st meeting.
