Proposed Schedule proceeding. The Parties discussed and respectfully propose the following procedural schedule for this Event Date Workshops August 20-21, 2018 Utilities To File Supplemental Testimony September 21, 2018 Pre-Hearing Conference TBD Intervenor Testimony December 14, 2018 1 July 31 st Ruling p. 1. 2

Event Date All Party Supplemental Testimony Regarding Nuclear Fuel Contract Cancellation Costs TBD (see note below SONGS Tour January 22, 2019 Rebuttal Testimony February 1, 2019 PHC TBD (as necessary Evidentiary Hearings February 25-27, 2019 Post-hearing Opening Brief April 12, 2019 Post-hearing Reply Brief May 17, 2019 Note Decision (D. 18-10-010 deferred the reasonableness determination on SONGS 2&3 nuclear fuel contract cancellation costs to the 2018 NDCTP to allow for a more complete record given the issuance of Decision (D. 18-07-037. 2 D.18-10-010 further provided that Parties may submit limited supplemental testimony and briefing as to whether and if so how D.18-07-037 impacts the determination of what should be deemed a reasonable expense to ratepayers for nuclear fuel cancellation costs. 3 The Parties will be prepared at the PHC to discuss the timing and format of this supplemental testimony or briefing. C. Scope of Proceeding 1. Recommended Scope Issues All Parties agree that the issues to be considered in this proceeding should include the reasonableness of: (1 the 2017 SONGS 1 Decommissioning Cost Estimate (DCE; (2 the 2017 SONGS 2&3 DCE; (3 2016-2017 SONGS 1 decommissioning expenses; (4 2016-2017 SONGS 2&3 decommissioning expenses; (5 the Utilities compliance with prior Commission decisions in the Nuclear Decommissioning Costs Triennial Proceeding (NDCTP; (6 each Utility s financial analyses and calculated customer contribution levels for their respective SONGS 1 and SONGS 2&3 nuclear decommissioning trusts (NDTs; and (7 status of the Utilities litigation against the government for recovery of damages related to the Department of Energy s (DOE failure to pick up SONGS spent fuel for offsite storage. 2 D.18-10-010, pp. 2-3. 3 D.18-10-010, p. 44 and Ordering Paragraph No. 7. 3

In regard to the issues all Parties have agreed should be within the scope of this proceeding, Intervenors have expressed that they will likely focus on the following: a Cal Advocates Cal Advocates states that it expects the contested issues to include the reasonableness of the SONGS 1 and SONGS 2&3 DCEs, and the Utilities decommissioning costs incurred during 2016-2017. 4 Cal Advocates also expects that the treatment of the SONGS 1, 2&3 offshore conduits will be an issue, as they were in A.16-03-004. 5 b TURN TURN states that it intends to thoroughly review the revised DCEs for SONGS 1 and SONGS 2&3 with a special focus on the arrangement between the SONGS owners and the Decommissioning General Contractor. TURN will also review approximately $312 million in decommissioning expenses incurred at SONGS 1 and 2&3 that has been submitted for a finding of reasonableness. 6 TURN intends to evaluate this spending consistent with the milestone framework proposed by parties in A.16-03-004. 7 TURN will also evaluate the treatment of Department of Energy Litigation and Claims Proceeds and trust fund return assumptions. 8 c A4NR A4NR questions the prudence of SCE s decisions that have impacted the decommissioning schedule with inadequate consideration of the impact on decommissioning costs. For the reasons stated in A4NR s Protest, A4NR believes that the utility testimony served to date has not met the utilities burden of proof that certain of the DCE cost assumptions are reasonable. A4NR has essentially completed its discovery, and anticipates raising other issues in its direct testimony that challenge the reasonableness of certain DCE cost assumptions. 4 ORA Protest, p. 4. 5 Id. 6 TURN Protest, p. 1. 7 Id. 8 Id. 4

2. Disputed Scope Issues a Palo Verde DCE (1 TURN s Position TURN asserts that the application fails to include any updated information about the anticipated costs or schedule for decommissioning the Palo Verde Nuclear Generating Station (PVNGS. SCE should be directed to identify the timing of any anticipated developments or updates that would affect the estimated costs of decommissioning. To the extent that the Commission adopts adjustments to the PVNGS DCE in A.16-03-004, as proposed in the pending Phase 2/3 PD, those revisions should be reflected in a revised cost estimate submitted into the record of this proceeding. (2 SCE s Position SCE believes that there is no need to review a Palo Verde DCE update in the 2018 NDCTP given that SCE so recently submitted the 2016 Palo Verde DCE for the Commission s review in A.16-03-004. SCE will revise the 2016 Palo Verde DCE to incorporate any changes directed by the Commission once a final decision is issued for 2015 NDCTP Phase 2/3. SCE proposes to submit the revised 2016 Palo Verde DCE in a Tier 1 advice letter or other filing directed by the Commission demonstrating compliance with the final decision. SCE believes the revised 2016 Palo Verde DCE should not be further reviewed. SCE anticipates that the next update to the Palo Verde DCE will be completed in late 2019/early 2020, and SCE proposes submitting it for review in the 2021 NDCTP. b Reasonableness of DOE Litigation Activities (1 TURN s Position TURN asserts that the Commission should clarify that the reasonableness of actions taken in the DOE litigation pursued by SCE and SDG&E should be reviewed in future NDCTPs. 5

(2 Utilities Position The Utilities have submitted the required testimony regarding the status of DOE litigation activities. The scope of future NDCTPs should not be determined on a prospective basis without consideration of what future circumstances may exist. Rather the scope of future NDCTPs should be determined based on the circumstances that exist when the Utilities submit applications to initiate those proceedings. c SCE s Recording Practices Of Staff Time To Undistributed Activities (1 TURN s Position In A.16-03-004, TURN proposed that SCE reevaluate its practice of recording disproportionate amounts of staff time to Undistributed Activities. The pending Phase 2/3 Proposed Decision agrees that TURN s proposal should be adopted on a going forward basis and directs SCE to meet with Energy Division staff and interested parties to address how it will provide better guidance to staff to ensure that future record keeping reflects support for Distributed activities. 9 Although TURN intends to participate in these meetings, there is no assurance that SCE will resolve TURN s concerns about the adequacy of the additional staff guidance and the portion of staff costs allocated to distributed projects. To the extent that TURN, SCE and other parties fail to reach agreement, the Commission should permit additional testimony or comments in this proceeding addressing unresolved issues. Any disputes should be resolved either as part of the primary decision in this case or through a supplemental decision or ruling. (2 Utilities Position The Utilities will adhere to the requirements of the final decision for A.16-03-004 and plan to hold meetings with Energy Division and interested parties in early 2019 to discuss this issue. The Utilities are hopeful that the issue can be resolved in these meetings. TURN proposes that in the event the Parties are unable to resolve the issue, the Commission should permit 9 Phase 2/3 Proposed Decision, A.16-03-004, page 43. 6

additional testimony or comments in this proceeding. However, the proposed schedule for the timing of the 2018 NDCTP, with evidentiary hearings scheduled in late February and posthearing briefing scheduled in April-May, 2019, will not allow sufficient time for this issue to be addressed in this proceeding. The Utilities recommend that the Commission allow the meet and confer process to unfold prior to making any scope or schedule decisions in the 2018 NDCTP regarding this issue. The Utilities will keep the Commission apprised on the Parties progress on this issue, as directed by Energy Division. d Timing Of Substructure Removal (1 A4NR s Position As noted above, A4NR will argue that the Utilities application and accompanying testimony provide inadequate support to find reasonable the 2017 DCEs for SONGS 1 and SONGS 2&3. A4NR has indicated that they have specific concerns regarding the alleged likely material impact on both DCEs of assumptions about the timing of removal of subsurface structures. 10 (2 Utilities Position While the Commission is responsible for reviewing the reasonableness of DCEs, the Commission is not the proper agency to consider issues related to the timing of the removal of SONGS subsurface structures. The removal of subsurface structures is a decision the U.S. Navy will make as the landowner. A4NR also misunderstands the timing issues, as the land will not be returned to the Navy until decommissioning is completed, which is forecast to occur in 2051. Consequently, any A4NR objection regarding the timing of the removal of SONGS subsurface structures assumed in the DCEs should be deemed to be beyond the scope of this proceeding. D. Other Matters Relevant to Resolving The Issues Raised By Parties in This Proceeding 10 A4NR Protest, p. 1. 7

The Utilities held a two-day workshop for August 20-21, 2018 to provide an overview of the approach used to develop the 2017 SONGS 2&3 DCE submitted for the California Public Utilities Commission s (CPUC review in the 2018 NDCTP, and explain the alignment of the Utilities showing submitted for this proceeding to the reasonableness review framework proposed by parties in A.16-03-004 (2015 NDCTP. In addition, the parties have engaged in discovery. The Commission s determination of the issues to be within the scope of this proceeding will provide necessary guidance regarding the scope of any remaining discovery.
