Testimony of Thomas Long on Quantitative Risk Modeling

This testimony addresses the following three topics: (1) shortcomings and limitations of PG&E’s quantitative risk models and the importance of calculating risk reduction to the optimization of risk mitigations; (2) PG&E’s continued practice of deferring important work based on reprioritization; and (3) the need to disallow certain capital expenditures that PG&E has incurred in order to remedy inaccurate, incomplete, and unsafe gas distribution records.
