In many cases, however, investigations are not yet at a stage where we can determine whether we are liable or, if the liability is probable, to reasonably estimate the amount or range of amounts of the costs. Estimates of our liability are further subject to uncertainties such as the nature and extent of site contamination, evolving cleanup standards and imprecise engineering evaluations. We review our accruals periodically and, as investigations and cleanups proceed, we make adjustments as necessary. The following table shows our accrued liabilities for environmental matters at December 31, 2024. Of the total liability, $14 million at SoCalGas is recorded on a discounted basis, with a weighted-average discount rate of 2.45%.ACCRUED LIABILITIES FOR ENVIRONMENTAL MATTERS(Dollars in millions) Sempra(1)SDG&E(1)SoCalGasManufactured-gas sites$34 $— $34 Waste disposal sites (PRP)(2)8 5 3 Other hazardous waste sites12 11 1 Total(3)$54 $16 $38 (1)    Does not include SDG&E’s liability for SONGS marine environment mitigation.(2)     Sites for which we have been identified as a PRP.(3)    Includes $6, $1, $5 classified as current liabilities and $48, $15 and $33 classified as noncurrent liabilities on Sempra
