The Discharger states that at approximately 7:14 a.m. on June 25, 2024, potable water was observed leaking at about 0.18 gallons per minute (gpm) into San Pablo Bay from a pin-sized hole in a pipe on the Marine Terminal. Potable water flow to San Pablo Bay stopped at approximately 07:40 a.m. It is estimated that 16 gallons of potable, EBMUD water flowed into San Pablo Bay. |
Upon discovering the leak, the Discharger isolated the damaged portion of the potable water pipe and placed a bucket under the leak. The Discharger used vacuum trucks to remove remaining water from the pipe. The Discharger collected two samples of the water and analyzed them for residual chlorine (because potable water onsite, supplied by East Bay Municipal Utility District [EBMUD], is chlorinated), indicating concentrations of 1.4 mg/L and 0.0 mg/L.
The cause of the potable water release was the development of a small hole in the potable water pipe, likely caused by external corrosion. The Discharger stated that the damaged portion of the pipe was being fixed and that it would inspect the pipe for other points of corrosion. |

pH Instantaneous Maximum limit is 8.5 SU and reported value was 8.64 SU at E-003A. |
-The majority of saltwater flow was redirected from the Safety Basin to Ditch #6. This has improved the average flow velocity of saltwater effluent thereby reducing the potential for excess algae growth within the Basin System/Ditch #6.
-The saltwater pumping rate was increased as much as feasible to minimize algae formation. |
