 are subject to requirements issued by the United States Environmental Protection Agency under the Federal Resource Conservation and Recovery Act in addition to other state laws relating to hazardous substances.  The Utility has a comprehensive program to comply with federal, state, and local laws and regulations related to hazardous materials, waste, remediation activities, and other environmental requirements.  The Utility assesses and monitors the environmental requirements on an ongoing basis and implements changes to its program as deemed appropriate.  The Utility’s remediation activities are overseen by the California Environmental Protection Agency, Department of Toxic Substances Control (“DTSC”), several California regional water quality control boards, and various other federal, state, and local agencies.The Utility’s environmental remediation liability as of March 31, 2025, reflects its best estimate of probable future costs for remediation based on the current assessment data and regulatory obligations.  Future costs will depend on many factors, including the extent of work necessary to implement final remediation plans, the Utility’s time frame for remediation, and unanticipated claims filed against the Utility.  The Utility may incur actual costs in the future that are materially different than this estimate and such costs could have a material impact on results of operations, financial condition, and cash flows during the period in which they are recorded.  As of March 31, 2025, the Utility expected to recover $1.1 billion of its environmental remediation liability for certain sites through various ratemaking mechanisms authorized by the CPUC.

Natural Gas Compressor Station SitesThe Utility is legally responsible for remediating groundwater contamination caused by hexavalent chromium used in the past at the Utility’s natural gas compressor stations.  The Utility is also required to take measures to abate the effects of the contamination on the environment.Topock SiteThe Utility’s remediation and abatement efforts at the Topock site are subject to the regulatory authority of the DTSC and the U.S. Department of the Interior.  On April 24, 2018, the DTSC authorized the Utility to build an in-situ groundwater treatment system to convert hexavalent chromium into a non-toxic and non-soluble form of chromium.  Construction activities began in October 2018, and the initial phase of construction was completed in 2021.  Additional phases of construction will continue for several years.  It is reasonably possible that the Utility’s undiscounted future costs associated with the Topock site may increase by as much as $220 million if the extent of contamination or necessary remediation
