CALIFORNIA WATER SERVICE GROUP

Due to terrorism and other risks, we have heightened security at our facilities and have taken added precautions to protect our employees and the water delivered to customers. In 2002, federal legislation was enacted that resulted in new regulations concerning security of water facilities, including submitting vulnerability assessment studies to the federal government. We have complied with regulations issued by the EPA pursuant to federal legislation concerning vulnerability assessments and have made filings to the EPA as required. In addition, communication plans have been developed as a component of our procedures.

In accordance with the 2018 America’s Water Infrastructure Act, we are required to conduct additional risk and resilience assessments (RRAs) and develop emergency response plans (ERPs) for each of our water systems. These RRAs and ERPs include natural hazards as well as malevolent acts. The first such assessments were completed in 2020. The RRAs are scheduled to be reviewed and resubmitted every five years.

While we do not make public comments on our security programs, we have been in contact with federal, state, and local law enforcement agencies to coordinate and improve our water delivery systems’ security.
