The spill was from two orphaned tributary sewers not owned or operated by the Los Angeles County Sanitation Districts (LACSD) that connect to the LACSD Oak Street-Center Avenue Trunk in La Cienega Blvd and terminate in the embankment where they were apparently abandoned during the 405 Freeway construction in the 1960s. The abandoned tributary sewers did not have functional plugs and were open to the LACSD sewer, which surcharged during the heavy rains on February 1, 2024, causing flow to back up into the two unsealed non-LACSD tributary sewers and spill onto the embankment. 33.954246 -118.369914 Drainage Conveyance System that discharges to surface water; Paved Surface; Unpaved Surface 02/01/2024 07:40 02/01/2024 11:00 Collection System Maintenance Failure (specify below); Other (specify below); Pipe Structural Problem/Failure - Installation Unsealed abandoned sewers (failed and/or missing plugs) The spill occurred from two unsealed abandoned non-LACSD orphaned tributary sewers.

Vitrified Clay 8 Other (specify below) LACSD installed temporary plugs on the two abandoned non-LACSD tributary sewers at their historical connection points to LACSD’s Oak Street-Center Avenue Trunk sewer. Permanent seals will be installed at the historical connection points by LACSD in place of the temporary plugs during an upcoming sewer rehabilitation project. LACSD sent a letter to Caltrans notifying them of the issue, explaining the precautionary actions LACSD has taken, and requesting that they construct plugs on the other (east) ends of the abandoned sewers along the Freeway embankment as required. Note that LACSD attempted to submit this voluntary spill report shortly after the spill but was unable to due to errors in CIWQS. Due to the errors encountered the report was emailed to DWQ-SanitarySewer@Waterboards.ca.gov and Afrooz.Farsimadan@waterboards.ca.gov on March 26, 2024. 895820 9 Robert Schouman 07/23/2024 07:47 1275 N SECOND ST 70 1275 N Second, Aprox 10 Feet in drivway at lateral 32.81296 -116.93543 Building or Structure; Street/Curb and Gutter (2 3); Unpaved Surface 07/23/2024 07:47 07/23/2024 08:01 Debris-Rags 1275 N Second 10 feet into driveway.

The cleanout is located in the N/E corner of the building. The flow from the spill was inconsistent as it would only spill when the toilets and sinks were being used. The spill traveled 150' to the storm inlet across the street. There was proof that this spill most has occurred at the cleanout location for the last few days as there was dried up toilet paper around the box. Total volume of spill is based off what could be calculated at the time we responded to spill. No assumption was made for volume of the dried-up toilet paper. The start time accounts for spill occurring prior to our notification. Assumption of 1 day prior due to dried up toilet paper. Water was turned off to business as there may be a cross-connection issue with clean out in meter box. 37.704793 -121.932193 01/06/2025 10:47 01/07/2025 13:30 The spill cause is due to a blockage in the private lateral.
