Order No. Linked To Enf. 1150564 06/30/2025 Order Conditions The Discharger contracted Miller Marine Science and Consulting to conduct the benthic monitoring for the 2024 Annual Monitoring Report required by Order No. R9-2019-0003. Miller Marine sub-contracted out to Physis Environmental Laboratories which is not an ELAP-certified laboratory. This is a violation of the Order as the Discharger is required to use ELAP-certified labs to comply with the monitoring requirements. Violation null Report Claude Bud Lewis Carlsbad Desalination Plant 430584 R9-2019-0003 N 1145518 06/25/2025 Order Conditions On Wednesday, June 25th, 2025, CDP conducted a planned replacement of rotary screen number three. Prior to the removal of the screen, the stop log was installed. Following the installation of the spare screen, the team removed the stop log. It was at that time they noticed that the installed screen did not align at the designated position. The crew then adjusted the screen to correct the alignment. During this adjustment the screen was lifted approximately 2 feet, while the stop log was removed. This partial removal resulted in unscreened water entering the treatment process for approximately one hour.
