From the the curb/gutter, the sewage traveled along the street and reached a nearby storm drain inlet. This storm drain inlet is connected to the City of San Jose's municipal storm sewer system. The sewage traveled within the storm system to a storm outfall discharge point along Berryessa Creek. Finally, the sewage reached Berryessa Creek while discharging from the storm outfall.

The First Responder documented a video of the spill appearance point upon arrival.  Video footage was used to estimate a flow rate for the spill.  The Responder gathered additional information from the Reporting Party (RP) to determine an approximate start time which was assumed to be an hour prior to the RP calling City's Dispatch/Call Center. The estimated flow rate was multiplied by the estimated spill duration yielded the total spill volume. To estimated the spill volume cleaned up and recovered, measurements were taken of the spill on land and within the storm drain conveyance system.	The methodology used to estimate the total spill volume for the SSO event was the flow rate and duration method. Video taken at the spill appearance point was compared to a controlled test overflow rate using a similar lower lateral cleanout lid. The First Responder gathered information from the Reporting Party (RP) to assume a reasonable start time. A total spill volume was estimated using both a flow rate and estimated duration. Recovered volume was estimated based on recorded measurements of the spill prior to cleanup. The measurements included affected areas on land and the spill dimensions contained within the stormwater drainage conveyance system. 	Debris-General		Gravity Mainline		Vitrified Clay		60	The spill required cleanup of the front lawn and driveway for the private residence at 2895 Postwood Dr. In addition, it was estimated that 53 gallons of raw sewage reached Berryessa Creek. Based on the visual inspection of the Creek the following day on 6/6/2023, there were no impacts to the Creek or wildlife identified. 	N	Cleaned Up (specify below), Contained All or Portion of Spill, Mitigated Effects of Spill (specify below), Other Enforcement Agency Notified, Property Owner Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		The First Responder placed sandbag at the storm drainage system entry point and inside a storm drain manhole to contain as much of the spill as possible.  Crew saw moving water in the storm drain system and followed the flow the outfall.  Crew noticed that location of outfall was not accessible for equipment.  Crew was able to see the outfall and moving water in the creek.  Thus, crew assumed that all of the spill that reached the Creek was already lost.  Crew set up equipment to clear the plug and performed cleaning up of the area and storm drain system as much as possible. Crew washed down and recovered all of the sewage and induced water from the furthest downstream containment point.  All of the spill on land and spill contained within the storm drain system was cleaned up.	Adjusted Schedule/Method of Preventive Maintenance, Enforcement action against Fats, Oil, and Grease (FOG) source, Inspected Sewer Using CCTV to Determine Cause		Corrective actions for the spill include the following:  1. Conduct FOG outreach by distributing Grease Flyers to the nearby residents. 2. Revise problem pipe mainline cleaning cycle from 8 years to 4 years. 3. Re-CCTV the problem pipe mainline to assess issues in 6 Months to identify potential blockages or debris buildups. 4. Identify any root intrusion in nearby sanitary pipe segments and add them to the City's Root Control Program. 5. Revaluate access to the storm drain outfall discharge point along Berryessa Creek.	1. Conduct FOG outreach by distributing Grease Flyers to the nearby residents. 2. Revise problem pipe mainline cleaning cycle from 8 years to 4 years. 3. Re-CCTV the problem pipe mainline to assess issues in 6 Months to identify potential blockages or debris buildups.	06-JUN-23	While the Responding Crew cleared the blockage in the plugged sanitary mainline, the Crew documented their findings. A pipe basket was used to collect the debris that was causing the blockage of the mainline. Crew collected what appeared to be a large piece of conglomerate of concrete and asphalt which was likely the cause of the blockage. After conducting a follow up CCTV of the sanitary mainline, there were no other significant observations or defects in the pipe that would've contributed to the blockage. Therefore, it was determined that the large piece of debris was the primary cause of the blockage and spill.

They sated they had been smelling this same odor for the last two weeks, they work on the boardwalk and have the same shift daily. We traced the piping back to a ship, the Horn Blower that is docked along the River. We went the following day and spoke to the captain of the ship, and gathered information pertaining to their discharges. We were told that they only operate 4 days a week and discharge nightly after returning to the dock. They have a 1000 gallon holding tank that is never full, and on average is half to less than half full when discharging is performed. It is usually around 8PM when this occurs, this supported the callers statement and information.

Based on our investigation it looks like very little if any material entered the storm drain.  This is based on the discharge locations that did not have any of the staining/growth that was present on the dirt.  	During our routine maintenance inspections, we found that a failed air relief valve caused a sewer spill that went into the Camarillo Hills storm drain. The start GPS coordinates are 34.215652, -119.079116 and the ending of the spill GPS coordinates are 34-215609, -119.081376. These coordinates represent the full spread and reach of the spill.	Y	34.215652	119.079116	34.215609	119.081376					07-JUN-23	In order to calculate the spill volume, we used two different methods. The first method was breaking the spill up into two sections and measuring the length of the spill x the width of the spill x the depth of the spill and converting that to gallons. The second method used was our pump station SCADA trend to determine the run time of the pumps since the last time the air relief had been checked. 1st section- 158 ft x 8ft x .33ft x 7.48= 3120 gallons 2nd section- 557 ft x 2 ft x .33 ft x 7.48= 2749 gallons for a total of 5959 gallons.	We used our last inspection date (12/15/2022) as the start time of the spill.  The end date of the spill (6/7/2023) was the date we found the spill.  Last date of inspection was Dec. 15, 2022.

The sanitary departments vacuum truck was used to pick up any standing water and a backhoe was used to remove any soiled dirt.	Adjusted Schedule/Method of Preventive Maintenance		The frequency of preventive maintenance was adjusted, and the visual inspection of the air relief valves was adjusted to a bi-monthly basis. We also have a containment system to capture anything that would release from the air relief valve and can hold approximately 30 days of material if we had a spill.  We also replaced the 2 other air relief valves on the line.	The above activities are complete.	09-JUN-23	After interviewing staff, it was determined that the inspection of the air relief valves should occur on a more frequent basis.  The line is not in area that is normally traveled, so staff has been directed to check these valves on a more regular basis and to keep better records on when the valves are inspected and checked.  The air relief valves were 11 years old, and the PVC material was old and brittle.  This is something that should have been identified on previous inspections and corrected.

Water from the broken line entered the storm drain that is adjacent next to the creek. The spill never reached the street surface which allowed it to remain unnoticed for so long. A houseless person that frequently sat under the bridge said he thinks it was flowing for 2 weeks. The line that backed up had a partial stoppage. The volume was calculated using a 5-gallon bucket. We timed how many buckets will fill in a minute. Five buckets were filled totaling approximately 25 gpm which we calculated by how long the sewer flow lasted. (See Timing 5-gallon bucket jpeg). The sewer line was partially plugged and still had flow entering the downstream manhole when the crew arrived.

However, we did not receive an exact ETA from the public works dispatch. In addition, we called the fire department, and they contacted the health department. We also contacted Ocean Blue to perform a spill cleanup. They cleaned and recovered the full 1800 gallons of sewage that spilled and the customer's backyard, driveway, street, curb, city catch basin, and LA county riverbed where the spill stopped. The 1800 gallons of the spill were fully recovered, and the spill has been cleaned.

I estimated a start time of 12:25pm to err on the side on the overflow.	Pump Station Failure - Mechanical	a part broke on the lift station pump	Manhole		Ductile Iron		25	The SSO was low threat to public health.  The spill consisted of grey water, which traversed a small section of asphalt to get to the gutter.  Once in the gutter, the grey water entered a storm drain, ran through a storm drain pipe, and terminated in a percolation pond.  There was minimal impact on the percolation pond as the grey water percolated swiftly.  	N	Mitigated Effects of Spill (specify below)		The City had a sanitary pump truck pumping at the lift station in efforts to prevent a SSO, however, the tuck could not keep up with the amount of flow.  Once the lift station pump was repaired, staff immediately  disinfected the roadway, gutter, and storm drain, which then provided disinfectant to the percolation pond.	Repaired Facilities or Replaced Defect		As the lift station currently has 1 pump, there is a bypass pump and piping staged in the immediate vicinity in the event of a catastrophic failure.  Staff immediately called the contractor to mobilize and set up the bypass, even close the roads to traverse the road with piping.  The contractor was 10 minutes away form start up of the bypass pump when I received word that the pump was repaired and functioning.  At that time, the wet well level dropped and the bypass was no longer necessary.  The second pump for this lift station was ordered in February 2023, and has just arrived.  I anticipate to have both pumps running prior to the end of July 2023.	Jan 2023- both pumps failed due to storm Feb 2023 -1 new pump ordered April 2023- 2nd pump had been re-wound, installed for solo use June 2023- new pump arrived, assembly scheduled. July 2023- complete drop in and start up of new pump July 2023- both pumps fully functioning, release of the staged bypass pump and piping	04-JUL-23	Due to excessive vibration of the pump, the filter assembly was constantly moving and eventually sheared off at the threads.

On 7/18/23 we hired WR Forde to emergency excavate over the blocked pipe and found it to be collapsed.	7	After leaving cleanout the spill traveled across sidewalk to the gutter pan and entered the catch basin further down the street.  This gutter pan has evidence of ground water year around with grass growing out of the cracks.  	Y	Upon entering the catch basin the spill continued down to a larger storm drain basin that collects water from 2 other pipes.  It then flows towards San Rafael Creek.   	7	0	All water found in the storm drainage system was clear and showed no evidence of debris due to the booms and filter fabric placed over and around the entrance to the storm drainage system.  	7	7	Drainage Conveyance System that discharges to surface water		When our crews arrived they did not witness an active overflow but did see wetness between cleanout and gutter pan.  There was ponded sewage in gutter pan.  The downstream catch basin had construction booms set up to prevent any solids from entering during the potable water main replacement however no sewage debris was found.

Pump one ran for 35 minutes and pump two ran for 30 minutes. 65 x 222 = 14430 gallons from the lift station. We then calculated the volume that would have been added from the gravity mains in the apartment complex That was 1878 gallons.  Total pumped and gravity flow = 16,308 The main from the lift station to the man hole that spilled is 990 feet and is a 6�pipe. The volume in that main that would not have flowed out is 1454 gallons.The volume of the spill appearance point manhole is 329 gallons based on a 48� diameter barrel and being 3.5 feet deep. Because this manhole is lower than the next upstream manhole on the gravity line we estimated that 20 feet of that main would have held water as well. This is an 8 inch main and its volume would be 52 gallons.  Total volume that remained in the collection system = 1835 gallons Therefore we estimated the spill volume to be 14,473 gallons (16,308-1835= 14,473)    	The estimated start time is 0647.

N						0	Unpaved Surface		Spill travelled across a paved road and partially saturated an unpaved surface adjacent to the road. 	Y	37.96412	-120.23397							29-AUG-23	Visual observations were primarily used. Operators determined a spill rate of 0.5 gallons per hour upon initial arrival; however, that flow rate increased by the following morning. That morning, the third party contractor arrived on site before operators did at 0700 hours and began vacuuming out the pit before operators could get an updated spill rate.   Operators are well trained in estimating spill volume over paved surfaces. The thirteen lateral connection count, extent of impacted area, and visual observations were all considered in estimating spillage volume. The reported 150 gallons is a conservative estimation where the lower estimation would be approximately 120 gallons.	Operators were on site twice from the time of initial notification to the time spillage stopped. The first time operators were on scene found a spill rate of 0.5 gallons per hour. The second time staff arrived on scene the spill had ceased due to the contractor vacuuming out the pit where the spill originated. Because of the lack of flow rate data, an exact spill estimation could not be determined.  	Construction Diversion Failure		Gravity Mainline		Vitrified Clay		72	Roughly 90 percent of the spill impacted a paved roadway. The remaining ten percent travelled off the roadway into an unpaved area. No sewer solids were observed at any point during mitigation efforts. The impacted roadway was pressured washed by the contractor followed by operators disinfecting all areas with E-SAN 205 disinfectant.  Nearby residents were notifed to keep pets and children out of the impacted area followed by 24 hours of contact time with the disinfectant. 	N	Mitigated Effects of Spill (specify below)		No solid sewer debris was present. The roadway was pressure washed and disinfected. No spillage volume was puddled and no spillage recovery resulted.	Other (specify below)	Directed third-party contractor to always backfill/support when temporarily connecting to an old pipe that have differing elevations.  	Investigatory efforts by the District uncovered that the third party contractor who is performing a sewer renovation project for the District installed a temporary connection tying a new mainline onto an existing clay pipe. The pit was left open with out backfill, this did not prove the needed support for the old pipe, and, as a result the clay pipe broke off entirely. This method the contractor used will be corrected in the general specifications during the next sewer renovation project.		29-AUG-23	The current Collection System Improvement Project calls for new mainlines to be deeper than existing mainlines. During the course of construction the contractor has to keep old and new sewer pipes intact. When construction ends in a particular location that is not completed the contractor will install a temporary drop connection, connecting the high existing mainline to the new lower mainline. This temporary connection was not supported in an y manner, such as backfill. As a result, the weight of the two pipes was more than the old VCP could hold and, consequently broke off in the trench. The trench was covered with trench plates and could not be removed with equipment staff had on hand. The contractor had to be called in to assist with removing the trench plates.  		No further investigating efforts will be undertaken by the District.	29-AUG-23														Not applicable	The contractor's methodology of making the temporary new to old mainline connection will be addressed in the standard specifications by the District's Engineering Dept. before the next phase of construction begins.	Not applicable	Scheduled to be replaced tomorrow, 30 August 2023.	Not applicable	The old VCP is scheduled to be replaced tomorrow, 30 August 2023.	The current sewer renovation project is funded through SRF with the Waterboards. It is required to submit a Completion Report following project completion. That report will include As-built drawings showing the section of failure had been replaced.	Sewer responses were limited due to the contractor's trench plate covering the location of failure. Operators did attempt to hydro-jet through a downstream manhole with no success. However, after seeing he cause of the failure, no hydro-jetting efforts would have alleviated the failure. The third-party contractor arrived on site first thing the following morning and corrected the failure. 	No further investigating efforts will be undertaken by the District.

The reference sheet has a flow rate estimate for overflows discharging from a manhole.  	The City of Beverly Hills utilizes the Smart Cover System to monitor sewer level at certain sections of the sewer system.  The Smart Cover System sent an alarm to staff on the day and time of the spill event.  Staff went to the site immediately and determined a spill was occurring.  The notification date and time were used as start time and date of the spill.   The spill end time was determined after the spill was stopped at the manhole.

Staff helped contained the spill as much as possible until the blockage was removed.   In terms of recovery, staff vacuumed the spill on the street, catch basin and storm drain. Staff also cleaned the affected areas as well.  The City went 0.3 storm drain miles downstream of the spill site to recover the spill and cleaned the affected storm drain. 	Inspected Sewer Using CCTV to Determine Cause		The particular sewer main is already in a priority 90-day maintenance schedule . The sewer main level is also monitored with the Smart Cover System.  The sewer level has remained consistent and no level increase has been observed by staff.  The Smart Cover System is effectively working for Beverly Hills. Staff responds to alarms including level rise or surges.  In terms of pipe integrity, the sewer main is plastic lined to prevent root intrusion or failures in proper function.   Based on the system in place, the SSO was not anticipated.  This was proven after a post SSO CCTV inspection.  A root ball from a lateral was identified.  City staff informed the responsible property on Aug. 24, 2023 of the event and highly recommended to coordinate future maintenance with the City to prevent overflow events.  	On 8/14/2023, City staff evaluated the affected sewer system and maintenance record to determine if the City was at fault of the spill.  City staff also reached out to property owners to see if any sewer lateral maintenance were being performed.   On 8/24/2023, a post-SSO CCTV inspection was completed and determined that a debris from a private lateral (root ball and other materials) were pushed to the sewer main and caused the blockage. On the same day, staff informed the responsible property owner of the spill and highly recommended to coordinate with the City on future sewer maintenance.   The City will continue to work with private contractors to coordinate sewer maintenance work with the City to prevent future spill events. 	14-AUG-23	City staff examined GIS maps and plans of the sewer main. The sewer main is in an aggressive maintenance schedule. It is also plastic lined.  The sewer main level is also monitored.  The sewer level has been consistently normal for many months.

Containment measures involved the placement of absorbent materials and barriers around the spill area to prevent further spreading. Cleanup efforts consisted of the removal and proper disposal of the spilled substance, followed by thorough decontamination of the affected area to mitigate any environmental or safety risks	Added Sewer to Preventive Maintenance Program, Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause		The spill corrective action plan involves a comprehensive strategy to mitigate and prevent future spills. This includes regular source inspections, ongoing training, improved response protocols, environmental monitoring, facility upgrades, and continuous regulatory compliance checks. Major milestones include initial inspections and training within the first year, with facility upgrades and comprehensive compliance reviews scheduled for subsequent years to ensure a systematic and effective approach.		14-AUG-23	The investigation into the cause of the spill, conducted by the Wastewater Collections Supervisor and his dedicated staff, revealed a comprehensive understanding of the incident. It was determined that the spill resulted from root intrusion into the sewage pipe. The team's meticulous investigation uncovered that the roots had penetrated the pipe, causing blockages and subsequent spillage through a lateral cleanout at 421 W. Fern Ave. This finding highlights the crucial role of regular maintenance and root control measures in sewage systems to prevent future occurrences of root intrusion-related spills.		Ongoing investigation efforts involve the continuous collection of data, root cause analysis, regulatory compliance reviews, and documentation maintenance to comprehensively assess the spill incident and take appropriate actions. These efforts are crucial for a thorough understanding of the incident, preventive measures, and compliance assurance.	10-AUG-23														In response to this spill, local regulatory authorities may have taken enforcement actions, such as investigations and penalties, as deemed necessary to address the illicit discharge, ensuring compliance with local environmental regulations.	To prevent recurring spills at the same location, it is imperative to make identifiable system modifications, including enhanced containment and drainage systems. Operational adjustments, such as stricter handling protocols and regular equipment maintenance, should be enforced, and maintenance programs need to be strengthened through proactive scheduling and comprehensive personnel training. These measures collectively aim to significantly reduce the risk of repeated spills at the same site.	The adjusted schedule and method of preventive maintenance involve optimizing maintenance activities to enhance equipment reliability and prevent breakdowns. This may include revising maintenance intervals, conducting more frequent inspections, and implementing condition-based monitoring to ensure proactive identification and rectification of potential issues before they lead to equipment failure.	The planned rehabilitation or replacement of the sanitary sewer asset is part of a Capital Improvement Program (CIP). This program strategically allocates resources to address aging or deteriorating infrastructure by either restoring the existing asset through rehabilitation methods such as lining or structural repairs, or by completely replacing it. 	We have conducted inspections and taken necessary actions to ensure the integrity and functionality of the assets. This includes the repair of any identified issues and the replacement of defective assets when required.	The planned rehabilitation or replacement of the sanitary sewer asset is part of a Capital Improvement Program (CIP). This program strategically allocates resources to address aging or deteriorating infrastructure by either restoring the existing asset through rehabilitation methods such as lining or structural repairs, or by completely replacing it. 	We have documentation that verifies the immediate implementation of system modifications and operating/maintenance adjustments, all facilitated through a virtual program that spans across the city. These documents include records of modifications made, dates of implementation, and relevant supporting evidence, such as photographs, reports, and work orders. This documentation serves to confirm the proactive steps taken citywide to enhance the system and maintenance protocols for spill prevention.	Modifications to spill response activities involve refining procedures to ensure a more efficient and effective response to spills. These improvements may encompass enhanced training for response teams, streamlined communication protocols to facilitate quicker coordination, and optimized resource allocation for prompt deployment. Additionally, community engagement initiatives may be implemented to raise awareness and improve public involvement in reporting spill incidents.

The park is closed for installation of new watermains, and the only sewage being received from the park is from the 8 employees living in the dormitory at the beginning of the system.  This sewage flows down another gravity section of the mainline to a lift station which conveys it across Hwy. 89 and to the high spot within the park where it changes again from force main to gravity which it flows down the mainline to the Tahoe City Public Utilities District and finally along Lake Tahoe.	38.98945	-120.09911	Gravity Mainline		Spill was contained to contractors' trench which took the sewage that discharged because the force main above turned on flowing from the upper part of the broken line back into the lower part of the mainline continuing its sanitary sewer flow to the Tahoe City Public Utilities District main trunk line.	1500	The State of Cal is installing new water line into DL Bliss SP and the contractor assigned to the project hit a gravity sewer main transporting sewage through campground.

N	Cleaned Up (specify below), Other Enforcement Agency Notified, Restored Flow, Returned All Spill to Sanitary Sewer System		The call came in after hours. A duty person was dispatched. When the spill was confirmed two vacuum trucks were on site within 45 minutes. One truck set up at the manhole that was spilling and stopped the spill immediately. The other truck went to the manhole downstream to break the blockage, clearing it within 5 minutes. The crew saw a corrugated pipe pass by the downstream manhole but was unable to capture it. Once the blockage was cleared, a crew removed 3600 gallons from the depression. The other crew went downstream and attempted to locate the pipe but were unsuccessful. The wastewater was flowing normally and they decided to come back in the morning. Staff washed down the asphalt and recaptured the water. In the morning staff went back to the spill site. The water in the depression was the same level as the night before and was not moving. An additional 3600 gallons of water was removed. Staff then found flexible pipe that had caused the spill downstream and removed it.	Other (specify below)	See section 10.b	The pipe that caused the spill is suspected to have come from a sewer construction project that had been occurring on the same street. Engineering staff have talked with Construction Management and Inspection staff to make them aware of the incident and have requested more rigorous inspections when construction work is in or near a sewer main.

(see attachment) Once it was removed from the sewer system, Engineering staff started looking at inspection logs from a sewer construction project that was in progress on the same street as the blocked sewer main. Staff determined from pictures of the construction work that the contractor used similar pipe for a flow-through plug for manhole rehabilitation work that occurred the week after the spill and surmised that the same pipe could have been used in the weeks prior to the spill even though there were no photos of the earlier work that showed the pipe.

The main is approximately 8 to 9 feet deep at this location.  Seepage above ground was noticed by the home owner at the location of origination in his driveway.  Cause of seepage could not be determined until line was excavated.	38.417383	120.832557	Force Main			2500	Spill was directed to an open grassy field on the property adjacent to the point of the spill appearance. Spill width was approximately 30'.  Spill length was approximately 70'.	N						1300	Unpaved Surface		The spill event destinations were a graveled driveway and parking area on the homeowner's property,  the bank of the driveway/parking area, and an open grassy field to the south of the residential property.

(3540 lin. ft. of 4  diameter force main=2310 gallons. Added 190 gallons for initial weeping liquid over bank).  The volume of the spill recovered was calculated using a portion of the 800 gallon VAC truck used.  It was filled once (650 gallon portion used for recovered volume) and partially filled a second time (550 gallon portion use for recovered volume). VAC truck stopped operating prior to completion of dewatering of excavation. Additionally, a septic hauler pumped the residence's pump tank during the repair and pumped an estimated 100 gallons out of the excavation.	The City was contacted by the homeowner at 19:30.  The City's representative was on-site at approximately 20:30.  At the initial point of origination liquid was bubbling and weeping out of the ground.  From the spread of the wetted area the estimated spill start time of 17:00 was arrived at.  The spill end time was stated as the time the repair to the force main was completed and tested.	Pipe Structural Problem/Failure - Installation		Force Main		Polyvinyl Chloride (PVC)	Failure occurred within a gasketed double bell repair coupling.  Failure occurred at what appeared to be  a seam in the manufactured part.	35	Spill initially flowed on the surface of the driveway and at a slow rate over the side of the bank at the driveway. Most of this stayed within the soil, but some moved to the grassy field to the south. During excavation of the repair trench the contractor dewatered the excavation with a pump instead of using the VAC truck.  This water was directed to the same area in the grassy field. The effluent in the force main is primarily treated at the City's aeration pond and screened prior to be pumped. There are no solids and just traces of paper.  The discharge infiltrated the soil and traveled on the surface down the slope leaving traces of sludge from the pipe.  Another discharge occurred to the same area when the VAC truck ceased working while emptying  the force main.  The discharge at the end of the operation contained a larger amount of sludge. All of this entered the grassy area in the field and infiltrated the soil. The discharge, except for wet soil, was kept off of the driveway.	N	Cleaned Up (specify below), Contained All or Portion of Spill, Mitigated Effects of Spill (specify below), Other (specify below), Other Enforcement Agency Notified, Property Owner Notified, Restored Flow	See comments regarding well in 13a.	The initial portion of the spill was contained in the saturated soil. Initial containment of the spill was hampered by the fact that the homeowner's septic pump tank located just downstream for the spill origination point could not get filled with liquid or have liquid spill into the lid due to  the electrical box location.  The excavated trench (up to 8 feet deep) contained the spill as work progressed. See Item 7. for additional spill information. The grassy field was sprayed with bleach solution on 09/11/2023.  On 09/13/2023 the spill areas in the field were raked, raked materials were hauled away, and a bleach solution was reapplied. The driveway area was repaired and a bleach solution was applied to the driveway/bank on 09/21/2023.  Bleach solution was not applied to the driveway/bank area on 09/11/2023 or 09/13/2023 due to the fact that the homeowner restricted access to the City's person applying the bleach solution.  Other accommodations were made. See Item 13a. regarding well.	Repaired Facilities or Replaced Defect		The spill originated from a broken coupling in the force main. This was repaired with a higher quality coupling.  It is believed that this is the first broken pipe problem on this force main since it was installed in 1975.  There are no records of other pipe repairs. The pressure on the main is visually monitored daily by the treatment facility's operator.  This will continue.	Pipe was repaired as part of the spill corrective actions.	22-SEP-23	The cause of the spill originated from a broken fitting on the force main. A VAC truck was on-site and was being used but better education of the Contractor workers regarding dewatering needs to be completed to emphasize keeping all of the spill contained. Additionally, in the future a larger, more reliable VAC truck needs to be on-site or on call to avoid having to redirect the overflow.	Y	The City is investigating the placement of the repair coupling at the residential pump tank connection in the immediate vicinity of the coupling and the origination point  of the line break/spill.  Additionally, there is a domestic well used for drinking water within approximately 60-70 feet of the origination point of the spill and within approximately 20-30 feet of the bottom edge of the spill area.  At the City's expense, testing of the well is planned for a duration of one year.  Two sets of test samples have already been taken.  The first sample taken on 09/13/23 has been returned with all results being clean.  The City has also authorized the homeowner to contact his well contractor to sanitize the well.  Additional doses of sanitizing will be discussed with the owner, the well contractor, and the Amador County Dept. of Environmental Health.	19-SEP-24										N												The City is investigating the placement of the repair coupling at the residential pump tank connection in the immediate vicinity of the coupling and the origination point  of the line break/spill.

During the bypass the pump failed around 9:30 AM and ended at 1:50 PM on august 31. Scada data from the lift stations during the time periods were calculated by the pump run times and GPM. The volume spilled during the pump failure was calculated using the SSCSC MH Overflow gauge at 400GPM. A portion of the spill has been recovered from the bioswales as water collects at the corners. To date, 47-9 yard tanks have been removed totaling approximately 85,000 gallons. (See Tara Hills Scada Data Attachment)	The spill was estimated to have started at 10PM on August 29. The caller called around 11PM and wanted to remain anonymous and wouldn't provide any other details. The lack of solids around the manhole suggested that the spill had recently started.

N	Cleaned Up (specify below), Contained All or Portion of Spill, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		A plug was installed in the overflow drain that leads to the next bioswale allowing us to completely contain the spill in the first three bioswales (See Picture Attached). Contaminated soil in the area around the manhole has been removed and replaced with mulch and rocks. WCW has contracted with ESA (Environmental Site Assessments) to provide an impact report and recommendations for remediation. Once the report is received, WCW will adopt one of the recommendations and move forward with remediation.	Plan Rehabilitation or Replacement of Sewer, Repaired Facilities or Replaced Defect		The valve that caused the spill has been repaired. WCW is in the planning stages of assessing, repairing and replacing pipes and valves on this 14,000 ft force main. See below:	1. Repair valve that failed causing spill--Complete 2. High Resolution Testing of force main--Summer 2024 3. Evaluation of data from assessment--September 2024 4. Prioritization of system repairs--December 2024 5. Force Main System Repairs--January 2025--December 2027 	14-SEP-23	The spill response is on-going as we continue to remove water from the bioswales, and remediation is still being planned. The spill was caused by the threads that failed at the bottom of the blow-off valve.	N												N

At 3:30 p.m. BM and Streets crews snaked the lateral and cleared the blockage. The next morning (09/26/23) BM returned to check the system, and observed a breakage in the lateral connection to the sewer main under the wharf and the lateral was leaking to the waterway below. BM staff immediately reported to their Manager who contacted the Public Works Director, who provided direction to investigate to Engineering who alerted the Harbor Office. From 8-11 a.m., BM staff troubleshoots the connection issue (faulty saddle connection) and uses a rubber gasket coupler to secure the lateral to the main and restore leak-free operational status.

Pardee Wastewater Maintenance staff will continue to perform the scheduled inspections, cleaning, and other maintenance activities for all wastewater collection, lift stations, and treatment systems.  In June 2023, as part of its FOG Program, EBMUD hand-delivered educational outreach material on protecting the sanitary sewer system to the mobile home occupants and long-term recreational vehicle park users. The material included information on how to properly dispose of FOG, in addition to a plastic grease scraper to encourage the occupant(s) to scrap up the grease from cooking utensils and properly dispose of it in the garbage (see attached sample of outreach material). 		12-OCT-23	On 10/7/23, occupant notified concessionaire, through voicemail of sewage smell around his unit. On 10/8/23, at 9:40 a.m., concessionaire notified EBMUD of reported sewage smell. EBMUD Oncall Assistant Superintendent immediately responded and inspected area where smell was reportedly coming from. No sewage spill was observed at that time. Occupant reported being away from his home since 9/16/23, last time no smell was detected.  On 10/9/23 at 10:25 a.m., EBMUD Maintenance Supervisor inspected area, including crawl space under mobile home where spill was detected. Spill was determined to be intermittent, based on wastewater-generating activities within occupied mobile homes that are serviced by impacted main sewer line. Once spill was detected, EBMUD deployed a hydrovac with cutter to dislodge obstruction. Line was cctv'd and pieces of FOG was observed floating on restored flow. The globules of FOG collected in downstream lift station and were later removed.		EBMUD cctv'd the main sewer lines servicing the mobile home park to identify the source of the FOG discharged through laterals.

Catch basin leads to the airport's storm drain conveyance system and to a downstream pump station.  The pump station was already isolated and shut off in dry weather mode.  During wet weather first flush operations by the treatment plant, the water within the pump station is pumped/diverted to an adjacent 1.5 million gallon capacity detention basin and until basin is full.  All wastewater from the detention basin is then returned to the treatment plant for processing.

Y	32.79753	-116.9337							24-SEP-23	The spill volume estimation was determined by measuring the area which contained the spill.  This area was measured at approximately 10'x25' with an average depth of 6  at 7.48 gallons per square foot = 935 gallons.  There was an additional area of 4'x4'x6 x7.48 = 47 gallons.  This totals 982 gallons.  Averages depths were estimated a bit high to account for soil absorption.  In addition the eyeball method was used to estimate the spill flow rate at approximately 10 gallons per minute.	Spill start time estimation was determined by reports from the onsite job foreman.  In addition, using the estimated duration of the spill (95 minutes) x the estimated flow rate (10gpm) = 950 gallons.  This is very close to the 982 gallon estimate from the measurements taken.

The cause of the blockage was a piece of debris possibly leftover from a prior maintenance effort.   A review of the SCADA system indicated that the overflow was short in duration. The cause was most likely the result of a  blow down  of a cooling tower, which sent a surge of water through the system. The surge of water combined with the reduced pipe capacity due to blockage led excess water to exit the nearest upstream manhole.   The SCADA system was monitored for any additional irregular flow.

Using the estimated spill duration of 20 minutes and standard average morning flow of 0.2 GPM per house hold, spill volume was calculated to be 56 gallons. This low volume is supported by the lack of any evidence of discharge.	The overflow was reported at 09:36 by a caller that left no return information. When the crew arrived at 09:50, the manhole was charged but not discharging. There was no evidence of a discharge, which indicates it was low volume and short duration. It was not possible to capture and return to sanitary sewer because it was raining. Therefore, estimed start time was before the call at approximately 09:20 and the end time was before the crew arrived at 09:50.

Upon arrival, crew lead Noe Corral met with the maintenance supervisor for the Marine Bureau, who showed him saturated sand in front of the restrooms. A leak in the sewer force-main caused the spill. Fortunately, the spill was contained within the sand. To prevent further spillage, the sewer pump station was turned off. The restrooms were subsequently closed until the pipeline could be repaired by an outside contractor.	33.76118	-118.157				2		N	N/A	0	0																04-AUG-23	The spill volume estimations were calculated based on visual observations and information provided by the parks, recreation, and marine supervisor.

As mentioned in the document, supervisory control and data acquisition (SCADA) records or flow monitoring data were not available for this specific spill. The supervisor noted the start time of the spill, and visual observations were used to estimate the duration of the spill. These estimations were made considering the minimal flow and the extent of the spill area.	Pump Station Failure - Mechanical		Force Main							Cleaned Up (specify below), Contained All or Portion of Spill, Other Enforcement Agency Notified		The immediate spill containment and cleanup efforts included the following steps: - The sewer force main, which was identified as the source of the spill, was repaired over the next several days by an emergency on-call contractor. - The contractor removed the sand and saturated soil from the spill area. - Flow was restored to the sewer system. - Following the completion of the cleanup and repair operations, the public restroom was reopened for public use.	Repaired Facilities or Replaced Defect																						Long Beach Health Department inspector supervisor Keith Allen was notified of the spill and our corrective actions taken. 	The pump station at S14 beach is routinely maintained by our treatment plant staff. As part of their regular visits, they perform visual inspections to identify any potential issues or abnormalities. This proactive approach helps ensure the proper functioning of the pump station and minimize the risk of spills.

The response crew implemented containment measures by placing barriers to prevent the further spread of the spill.	Y	The spill affected a Long Beach Public Works gutter catch basin. This catch basin is connected to a storm drain and a stormwater vault. The purpose of this system is to collect runoff from Pacific Coast Highway and transport it to other stormwater conveyance systems.	600				631	Drainage Conveyance System, Street/Curb and Gutter (2 3)		The sewage exited the system at the 6  city sewer lamp hole on PCH and traveled 600 feet down the street curb and gutter into the Long Beach storm drain catch basin. Sandbags were strategically placed to contain the spill at the street curb and gutter. The vault collected the spill, and Ocean Blue was able to vacuum and clean the street, gutter, and conveyance system.	Y	33.77282	-118.11933							09-DEC-23	The spill volume was determined using the formula (Length x Width x Depth) + (Area x 7.48). In this case, the dimensions were 600 feet x 0.33 feet x 0.0208 feet x 7.48, which resulted in 30.80 gallons at the street curb and gutter. Additionally, the spill volume at the Conveyance system was calculated by multiplying 5 gallons per minute by 120 minutes and adding 600 gallons, resulting in a total of 631 gallons.	Upon discovering a sewer spill at 5305 E. Pacific Coast Hwy, the manager of Greenfield Restaurant, promptly contacted Long Beach Utilities (LBU) to report the incident. The manager reported noticing the spill at 10:00 am, but it was already reported to LBU at 9:55 am by another party. The spill had a flow rate of 5 gallons per minute (GPM) over a period of 120 minutes, resulting in a total volume of 600 gallons. Visual observations were also used to calculate the volume in the curb and gutter (31 gallons). The total spill volume was 631 gallons.	Fats, Oil and Grease (FOG)		Gravity Mainline		Vitrified Clay		62	The spill had a localized impact on the area surrounding the 6  City sewer lamp hole on Pacific Coast Highway in Long Beach. It initially spread down the street curb and gutter and entered the storm drain catch basin. However, containment measures were quickly implemented to prevent further spread. The spill affected a Long Beach Public Works gutter catch basin, which is connected to a storm drain and a stormwater vault. The spill was successfully contained and cleaned up by Ocean Blue, who vacuumed and cleaned the street, gutter, and conveyance system. The spill volume was estimated to be approximately 31.17 gallons at the street curb and gutter, and an additional 600 gallons in the conveyance system. 	N	Cleaned Up (specify below), Restored Flow		The response team quickly implemented containment measures by placing barriers to prevent the further spread of the spill. Sandbags were strategically placed at the street curb and gutter to contain the spill. Additionally, Ocean Blue promptly vacuumed and cleaned the street, gutter, and conveyance system to ensure proper cleanup and prevent any further environmental impact.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause		The Pipe segment has undergone thorough hydro-jetting and has been added to our list of hot spots. It will be maintained frequently. We will continue with our preventive maintenance program and ensure that our staff follows proper cleaning practices.		09-DEC-23	On 12/11/2023, a post-CCTV inspection was conducted to investigate the cause of the main line stoppage. The inspection revealed that the main cause of the stoppage was grease. To address this issue, a thorough hydro-jetting process was performed on the affected pipe segment. This process effectively removed the accumulated grease and restored the flow of wastewater.		No ongoing investigation at this time.	11-DEC-23														The Long Beach Health Department was notified and arrived at the scene to supervise the cleanup of the contaminated area. The Long Beach Health Department will conduct FOG inspections, specifically at Greenfield Restaurant, as it is the only lateral tap on this mainline. These inspections aim to identify FOG-related concerns and ensure compliance with regulations.	This pipe segment has been added to our list of hot spots that require more frequent attention. We will also investigate the reason for the grease discharge by conducting a FOG inspection.	This Pipe segment will be maintained every 90-days, as part of our Hot Spots List.	There is no planned rehabilitation or replacement of this segment.	CCTV inspections were conducted to identify the cause and precise location of the grease blockage. Once the cause and location were determined, appropriate measures were taken to thoroughly clean the blockage and interior walls.	None planned.

The Hazen-Williams gravity flow calculation method was used. We assumed the flow filled 10% of the pipe volume, based on visual assessment. The truck that carried the 2,000 gal to the bioretention had a 2,000 gal volume capacity. The truck took two trips to the bioretention.

Adjusted Schedule/Method of Preventive Maintenance, Plan Rehabilitation or Replacement of Sewer	Add outreach materials locally for prevention of FOG into sewer and adding city-wide distribution of notice to contact DPW or APD to report spills.	The underlying cause of this spill is FOG.  This line is already a hot spot and is cleaned every 6 months.  We have increased the cleaning cycle to quarterly.  We are also engaging with EBMUD to send FOG information to properties tributary to the SSO through the regional FOG Program.  The City is in the process of relocating and upgrading this line to a parallel street to the south (Brighton Ave). The replacement line will be appropriately sized, sag free and will have better maintenance access, all of which will provide better protection from the creek. Construction of this replacement line is targeted for FY26.   	The increased maintenance schedule will be implemented immediately. The replacement project is targeted for FY26.	14-JAN-24	Upon determining the mainline section were the blockage happened and using the City's system maps, the Crew identified the most accessible maintenance hole down stream of the blockage. The Crew then began flushing the line upstream until hitting the blockage and then breaking through it. As part of the cleaning process, a mesh basket is inserted into outlet of the maintenance hole to catch the solids/debris causing the blockage, which in this case was grease and general debris.

The spill left the system and entered the city curb and gutter, with approximately 100 gallons contained on the street. Additionally, 50 gallons entered the conveyance system where it was contained. The remaining 1,650 gallons entered a separate catch basin, which leads directly into the marina. 	33.75653	-118.11183	Lateral Clean Out (Public), Manhole		The Spill originated from a City sewer manhole at 6550 E.

Sewage overflowed from a city sewer manhole, traveled down the gutter, and entered the Long Beach storm drain catch basin. It then flowed down the storm drain pipe into the Marina ( Alamitos Bay). 2. Sewage overflowed from the lateral clean-out public and, entered the Long Beach Storm drain catch basin, and flowed down the storm drain pipe into a storm drain manhole, where it was contained and fully recovered by Ocean Blue.	Y	There were two conveyance systems involved in the incident. The conveyance system closest to the clean-out received 150 gallons of sewage, which was fully recovered. However, the catch basin closest to the sewer manole flowed directly out to the marina and was not recovered. As a result, sewage overflowed from the city sewer manhole and entered the storm drain catch basin. From there, it flowed down the storm drain pipe into the Marina.	50	0	The conveyance system in this area consists of a storm drain catch basin that connects to a storm drain pipe. This system is designed to transport rainwater directly into the Marina.	1650	150	Drainage Conveyance System, Drainage Conveyance System that discharges to surface water, Paved Surface, Street/Curb and Gutter (2 3), Surface Water		This event consisted of one blockage, which resulted in a sewer spill at two locations of appearance. At spill appearance point 1, the spill left the system and entered the city curb and gutter, with approximately 100 gallons contained on the street. Fifty gallons entered the conveyance system located on Marina Dr., and all 150 gallons were recovered by Ocean Blue Environmental. The remaining 1,650 gallons entered a separate catch basin at spill appearance point two. This catch basin has a short segment of pipe that leads directly into the marina. This sewage was not recovered.	Y	33.75336	-118.1095							28-OCT-23	Sewage overflowed from City Sewer Manhole S04-SMH-029 at approximately 10 gallons per minute (gpm). I used a spill estimation chart to approximate the amount of gallons coming out. Then, I multiplied that by the number of minutes, the spill was active to determine the total amount spilled.	After speaking with the manager of San Pedro Fish Market and reviewing the video provided, it has been determined that the spill began approximately 30 minutes before the video was recorded. The video was taken at 1:01 p.m., so we estimate that the spill started at approximately 12:30 p.m. 	Damage by Others Not Related to Collection System Construction/Maintenance, Fats, Oil and Grease (FOG)		Gravity Mainline		Vitrified Clay		66	Approximately 100 gallons of sewage spilled onto the street, posing a health risk to pedestrians and causing environmental contamination if not properly cleaned.

Fifty gallons entered the conveyance system on Marina Dr., which can potentially lead to the ocean but was contained and recovered. All 150 gallons were contained and recovered, but the remaining 1,650 gallons entered a separate catch basin leading to Alamitos Bay, impacting marine life and water quality.	N	Cleaned Up (specify below), Other Enforcement Agency Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		1. Spill Containment:     - At spill appearance point 1, where approximately 100 gallons of sewage spilled onto the street, containment measures were implemented to prevent further spread. Barriers were deployed to contain the spill within the affected area.     - For the 50 gallons that entered the conveyance system on Marina Dr., containment measures were also implemented to prevent further discharge into the ocean. Dams were used to contain the spill and prevent it from reaching the water of the state. 2. Cleanup Efforts:     - Ocean Blue Environmental immediately initiated cleanup operations for the spill on the street. The 100 gallons of sewage were promptly cleaned up using pressure washers and a vacuum truck.     - To address the 50 gallons of sewage that entered the conveyance system, cleanup activities were conducted to recover the spilled sewage. Ocean Blue Environmental used a vacuum truck to flush the system, removing both sewage and nuisance water.	Enforcement action against Fats, Oil, and Grease (FOG) source, Inspected Sewer Using CCTV to Determine Cause		The following major milestones have been identified for the corrective action plan: -FOG Inspections by the Long Beach Health Department     - Target Start Date:10/31/2023     - Actions: Perform inspections on nearby restaurants to identify FOG-related concerns. - Addressing FOG Concerns at PCH & 2nd Outdoor Mall     - Target Completion Date: 11/1/2023     - Actions: Collaborate with the operations manager to ensure regular cleaning of interceptors and proper management of FOG. Utilize CCTV inspection equipment to identify the source of FOG and conduct more frequent inspections. - Emergency repair due to possible cross bore in the sewer mainline not caused by CS.      - Target Completion Date: 11/30/23     -Actions: Monitor and clean the main until repairs are complete  Collaboration with the Long Beach Health Department to ensure compliance. This segment of the pipeline is also included in our 90-day repeat cleaning schedule. We will ensure proper cleaning practices by staff.	The major milestones for the corrective action plan include pipeline inspections and FOG inspections by our Long Beach Health Department team. These actions were initiated yesterday, on 10/31/2023, and will continue until 11/1/2023. The pipeline inspections aim to assess the condition of the sewer system and identify any potential issues or blockages. The FOG inspections conducted by the Long Beach Health Department team will help identify FOG-related concerns and address them accordingly.	28-OCT-23	The sewer spill occurred due to a grease blockage in the sewer system. This hindered the flow of sewage, causing an overflow onto the street and into the conveyance system. A CCTV inspection was conducted to locate the blockage, revealing a cross bore protruding through the center of the 12  mainline, obstructing the flow. This finding will be escalated to the engineering team as an emergency. Immediate action was taken using hydro-jetting equipment to remove the blockage and restore normal sewage flow. The presence of grease indicates potential issues related to fats, oils, and grease (FOG). Restaurant inspections have been scheduled in the area.

According to their observation, the spill started at 8:00 am, and the manhole began seeping at 11:30 am. Unfortunately, we could not determine the spill rate due to the intermittent low leaking volume. As a result, we relied on the amount of sewage our contractor, Ocean Blue Environmental, recovered to calculate the spill volume.	The Crew conducted a field investigation.

MacArthur Blvd private property, travelled down private ribbon gutter to the City Street, then travelled westerly along MacArthur Blvd gutter to the County Storm Drain inlet. The catch basin is located at easterly corner of MacArthur Blvd at Harbor Gateway North.  SSO was contained by 15:45 Hours with sandbags, upstream of catch basin.

Y	County drainage system at SSO point of entry is a 5'X7' Box (county designation D03 P01) that conveys storm flow about 4,400 feet south to an open trapezoidal channel.

MacArthur Blvd. The SSO resulted from a stoppage in the CMSD public sewer within an easement on private property. Sewerage ponded on private property and spilled onto a adjoining private property (1561 W. MacArthur Blvd), to a private ribbon gutter, then to the street. At the street, the SSO travelled westerly to a catch basin to the County storm drain system located at southeasterly corner of Harbor Gateway North and West MacArthur Blvd.	Y	33.701786	-117.922197							21-DEC-23	The properties stopped using water prior to arrival at the SSO location. So only a trickle of flow was in the gutters. The District and their consultant used the photos showing evidence of SSO flows in the gutter (width, depth, slope of gutter, and gutter dimensions) along with Manning's  hydraulic equation to determine flow volume/rate.	The estimated spill start was based on the property owner report that sewage was coming our the bathroom floor drain (2:27 PM). That property owner called the neighboring properties to learn that they were also having issues, but no spill. The property owners initiated a shutdown of water use. When the District arrived at 3:30PM and set up containment, the SSO flow was none-existent to a trickle, depending on location. The containment only captured residual flow within the gutter and was vacuumed up by the District Vactor unit.  The initial onsite estimate was based on the District Engineers understanding of the 9 acre sewer shed and maximum flows. The District Engineer used 4.5 gpm for an estimated 90 minute period of active flow. The follow-up calculation used engineering calculations, measurements of the gutter, and measured gutter slope to determine maximum flow rate. Because property water use was curtailed, the flow varied during the 63 minute period prior to setting containment.	Debris-Rags, Debris-wipes/Non-disposables		Gravity Mainline		Vitrified Clay		57	There was minimal impact to the affected private property as they vacuumed spilled sewage off the bathroom floor and the ponding relieved itself into the business floor drains at the process area(s). About 200 gallons of sewage entered the storm drain system. Due to the rain storm ending the morning prior to the afternoon spill, the County health typical posts beach warnings about impacted runoff. 	N	Contained All or Portion of Spill, Other (specify below), Restored Flow	Used one District vacuum truck to clear the stoppage and a second vacuum truck to vacuum contained sewage and washdown water.

Upon arrival, District staff set containment, called for the vacuum trucks, and worked with the property owners to clear the stoppage and clean up involved properties. 	Other (specify below)	District will send  What to Flush  literature to the properties upstream of the stoppage.

The District will also review the subject sewer in 9 months, instead of the normal 12-month cleaning schedule, to determine if enhanced cleaning is required. The subject sewer was cleaned about 10 months prior to the SSO.

We then used ammonia test strips to get a base test of what was in the system without the spill, and an actual result at the entrance into the drainage system.

They then tried to contain the spill that was active by placing debris in the spills path to the gutter drain. Once the spill was relieved they began testing and trying to find the endpoint, they tested at the sump and got a negative test and then had a valve closed to keep the spill in the conveyance system. Knowing that it was trapped they calculated what was in the drainage system in between the valve and the entrance into the system. And removed all of what was in the system that contained the spill. 14,500 gallons was removed in order to capture the 3,460 gallons of the spill and returned to the sewer system. At the appearance point site all debris was removed from the area and it was thoroughly washed down and cleaned from the manhole, to the gutter drain the spill entered.	Added Sewer to Preventive Maintenance Program, Inspected Sewer Using CCTV to Determine Cause		After finding the cause of the spill, the main was cleaned and roots removed from the segment. This has all been completed within the last few weeks.	The spill was added to our root abatement work orders and will have maintenance performed  annually. 	11-DEC-23	We found this spill was on a chemical root removal program schedule, and when the program ended it was never put on a new schedule to be maintained.

Upon arrival, the standby crew lead checked the manholes in the area and found them to be full. While continuing the investigation, he discovered a manhole with sewage seeping out of a pick hole. He immediately called standby supervisor II and informed him about the positive spill. To contain the sewage, he used sandbags while waiting for the standby helper to arrive. Luis also took photographs of the spill boundaries. When the second team member arrived, they cleared the stoppage between sewer manhole G15SMH-049 and 2G15-SH-048, which was caused by grease.

The spill was not continuous but estimated to be approximately 1 gallon every 10 minutes. Visual observations indicated that the curbing gutter was approximately 2 feet wide and 8 feet long, containing about half an inch of liquid. Similarly, the spill in the alleyway was approximately 2 feet wide and 8 feet long, also containing about half an inch of liquid. This resulted in a total of 10 gallons.	The spill start time and spill end time were estimated using visual observations of the sewage seeping out of the manhole pick hole. It was assumed that the flow rate of the spill remained relatively constant throughout the observation period, and that the estimated flow rate represented the overall spill duration. The crew relied on visual observations of the spill and its boundaries, as well as calculations based on the amount of water spilling, to estimate the spill duration.

It was assumed that a typical diurnal residential flow pattern experiences a maxim flow rate from 6:00 to 12:00, 75% of the max flow from 12:00 to 18:00, 65% of the max flow from 18:00 to 24:00, and 15% of the max flow from 24:00 to 6:00. A total spill volume was estimated using this diurnal flow pattern and an approximate duration of the spill. For the spill on land, the Crew used approximate measurements to estimate the recovered volume. Lastly, for the spill recovered from the storm drain system, an approximate depth of flow was measured while tracking the spill. The depth was applied to a partially filled cylinder calculation to estimate a volume for each of the storm drain pipes. This volume in the storm system was assumed to be 50% sewage and 50% stormwater based on the concentration of ammonia (1-3 ppm).	The reporting party first noticed the spill on 1/13/2024 at 18:00. At that time, the reporting party stated that the spill had only traveled approximately 150 ft from the appearance point and had not yet reached the nearby storm drain inlet. Based on the reporting party's information, it was assumed that the SSO likely started shortly before the reporting party noticed. The start time of the SSO is assumed to have started around 17:00 on 1/13/2024.	Other (specify below)	Sewage overflowed from a sanitary sewer manhole due to a blockage in the downstream mainline pipe. The cause of the blockage was a combination of roots, rags, and an unknown metal obstruction. This metal obstruction appeared to be a large nail.	Gravity Mainline		Vitrified Clay		65	The spill required cleanup of the street curb and gutter in front of the property at 3398 Mt Madonna Dr. In addition, it was estimated that 22,465 gallons of raw sewage reached Lower Silver Creek. Based on the responding Crew's visual observations, there was no adverse impact to the environment or wildlife at the time of the spill. The City of San Jose Environment Department conducted a creek walk to assess the impact to the waterway on 1/18/2023. The result of the creek walk also showed no impact to the creek or wildlife. 	Y	Cleaned Up (specify below), Contained All or Portion of Spill, Other Enforcement Agency Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		Upon arrival, the responding City Crew immediately placed sandbags around the nearby storm drain inlet where the spill had entered. The Crew tracked the spill in the storm drain conveyance system (MS4). It was discovered that the spill discharged out from a storm drain outfall into Lower Silver Creek. The Crew then placed sandbags in a storm drain manhole to contain the spill and stop any further discharge to the Creek. Once the blockage was cleared and the spill stopped, the Crew began their cleanup efforts. At the spill source point, a Crew flushed sewage from the asphalt and curb to the nearby storm drain inlet. Water was used from a nearby hydrant and Vacuum truck to clean all of the spill on land. The hydrant hose and Vacuum truck then flushed the storm drain system with water at the affected inlet. Another Vacuum truck was positioned at the downstream sandbag containment within a storm drain manhole to recover all of the induced water and sewage from the MS4.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause		The City has planned the following corrective actions for this sanitary sewer overflow:  1. Adjust the plugged pipe segment operation and maintenance cleaning frequency from 7 years to 2 years. 2. Re-video the plugged sanitary pipe segment along with the upstream and downstream segments in 12 months. 3. Add the the plugged sanitary pipe segment along with the upstream and downstream segment to the City Sewer Root Control Program.	The City has scheduled following corrective actions for this sanitary sewer overflow:  1. Adjust the plugged pipe segment operation and maintenance cleaning frequency from 7 years to 2 years - completed on 1/24/2024 2. Re-video the plugged sanitary pipe segment along with the upstream and downstream segments in 12 months - scheduled for 1/13/2025 3. Add the the plugged sanitary pipe segment along with the upstream and downstream segment to the City Sewer Root Control Program  - added to the program list on 1/24/2024	14-JAN-24	While the Responding Crew cleared the blockage in the plugged sanitary mainline, the Crew documented their findings.  A pipe basket was used to collect roots, rags, and a piece of metal that was removed while clearing the blockage within the mainline.  After conducting a follow up CCTV of the sanitary mainline pipe, there were no other major O&M observations or structural defects that may have contributed to the blockage. Therefore, it was determined that the cause was a combination of roots, rags, and a foreign metal piece (nail).	N			Lower Silver Creek	River		Lower Silver Creek is a 4.7-mile-long northwest and westward-flowing stream currently originating just north of Lake Cunningham in Evergreen Valley in southeast San Jose, California. It is tributary to Coyote Creek, whose waters flow to the south end of the San Francisco Bay. Lower Silver Creek is not intended for recreational usage.	During the spill response, there was no adverse impact to the environment or wildlife observed. The following Tuesday, 1/16/2024, an inspector conducted a follow up storm drain outfall inspection.

All standing spill water was vacuumed and dumped in the WWTP Headworks grit chamber. 	While two operators worked to clear the blockage another operator used surrounding dirt to dam spillage from flowing into a drainage channel. A vac-truck was used to remove all ponding water. Approximately 100 gallons of potable water was used to dilute remaining spillage and wash off portions of the roadway that was in contact with sewage. The site was then disinfected using E-SAN 205. The driveway where the spill collected belonged to two residents. One resident was verbally notified and another was notified via written note, asking they contact the District for investigation purposes. 	Added Sewer to Preventive Maintenance Program, Adjusted Schedule/Method of Preventive Maintenance		The downstream segment where roots were found will be added to a priority annual maintenance schedule, and will include more frequent hydro-jetting and root prevention chemical application (RootX). 		02-NOV-23	Operators recovered a large root-ball following blockage clearing. The landscape above the failed pipe segment is a combination of thick vegetation comprising of trees, shrubs, and vines. Operator Colton McMullen stated he drove by the spill site the previous day just after 1500 hours. This would put the maximum spill duration at 20.2 hours. 		Still waiting to hear back from one neighbor. A business card was left on their door asking them to give the District a call. 	06-NOV-23														N/A	The segment where the failure occurred will be added to a more frequent maintenance schedule.	Yes, annually.	While the District has a long term plan to replace the entire collection system, it will be at least 10 years before this basin is replaced. 	Root intrusion is common throughout the older parts of the entire collection system. The section where the blockage occurred will be added to a more frequent maintenance schedule until replaced. 	While this section was constructed approximately 53 years ago, there are other higher priority basins that are over 73 years old. The District is currently in the planning stages of replacing those older basins, and will then address the basin where this spill occurred. 	The District does not have a documentation system in place. Hot spots in the collection system are added to operator's computer calendar as a reminder to perform scheduled maintenance tasks. The District is in the process of purchasing and implementing a Computerized Maintenance Management Program that will generate scheduled work orders. That system is expected to be in place by October 2024. 	No modifications were made to the operators' response. 	Still waiting to hear back from one neighbor. A business card was left on their door asking them to give the District a call.

We took pictures of the flow coming from the manhole and then compared them to our spill estimation pictures, and matched the two at 10gpm. We used documented times from when the spill first started at the manhole to when the plug was relieved 13 minutes to get 130 gallons. There was already a spill appearance point that was not active at the property line cleanout. This area was measured and a volume calculation was used to get this portion of the spill 2 gallons, we added this to the estimated total that was captured on the surface.

Responders blocked off the drain inlet upon arrival trapping a portion of the spill on land and had the supervisor turn off the drainage sump station downstream. Once the plugged main was cleared crews tested the drainage system to see how far the spill had traveled. With what was captured on the ground they determined there was 10 gallons that made it into the conveyance system. The drainage system already had water in it from the previous rain storm. It was determined that there was 2,259 gallons of water already in the system. Crews removed 3600 gallons of water to recover the 10 gallons.

N			Guadalupe River 	River		The Guadalupe River mainstem is an urban, northward flowing 14 miles through the Santa Clara Valley originated in the Santa Cruz Mountains. The river mainstem begins on the Santa Clara Valley floor when Los Alamitos Creek exits Lake Almaden and joins Guadalupe Creek just downstream of Coleman Road in San Jose, California. From here it flows north through San Jose, where it receives Los Gatos Creek, a major tributary. The Guadalupe River serves as the eastern boundary of the City of Santa Clara and the western boundary of Alviso, and after coursing through San Jos�, it empties into south San Francisco Bay at the Alviso Slough.

Y	33.690947	-117.925801							27-DEC-23	An engineering consultant was hired to calculate the flow estimate. The consultant used the gutter pictures to estimate and measure the flow width in the gutter. Consultant conducted a site visit and measured slope, gutter width, gutter cross slope, and verified estimated flow width from photos.  The calculated and measured data was used to determine flow depth and volume at 1 gpm maximum.  It is likely that the flow varied and the average flow was less than the maximum. However, because data indicating how the SSO flow varied with time, the maximum flow was used to provide a conservative flow estimate.  The flow start was determined by a resident interview (1657 Iowa). The resident indicated that he noticed the flow had started about an hour prior to the District arrival. Based on SSO start and stop time(s), 1 GPM for 75 minutes is 75 gallons into the drainage system. 	Used a resident observed start time (11:45 AM), District noted arrival and SSO relief time (1:00 PM), for a total flow time of 75 minutes..

SSO occurred due to a blockage in the sewer main. On arrival at the primary SSO site, SSO was spilling onto the asphalt and flowing to both sides of Kansas Ave. Containment berms of dirt, sandbags, gravel bags, wattles, and road base material were constructed to contain sewage on both sides of Kansas Ave. Flow from the manhole was slowed by placing sandbags and gravel bags on top of the manhole where the flow was originating and diverting and directing the SSO to one side of Kansas Ave (south side). The secondary SSO site occurred during cleanup operations located at the next manhole downstream, located on Kansas Ave, next to the entrance to SLO County Fleet Services.	35.320433	-120.719315	Manhole		Secondary SSO site occurred during cleanup operations by FRM (contracted collection systems maintenance provider). During Vactor operations to clear the line blockage, backed up sewage surged out of the manhole and poured onto the asphalt and ultimately spilling onto the dirt embankment on the south side Kansas Ave. SSO was absorbed into the dirt at this location. SSO did not reach the nearest storm water conveyance or drainage, approximately 150 ft west of secondary SSO location. Approximately 1800 gallons of sewage was recovered at this site during blockage removal.	2700	Photos submitted as attachments.	N						0	Unpaved Surface		Primary SSO site.

Y	35.32718	-120.719132							20-NOV-23	Used two methods to estimate spill volume. 1) visual comparison to photo slides representing various flows originating from a manhole (DKF slide)., and 2) measurement of the SSO spouting out of the manhole and using a table with representative flow values to determine the flow rate of the SSO. Assumptions used in calculations. 1) SSO flow was constant over duration (108 minutes) of the SSO. 2) DKF table used in the spouting flow model correlates with the actual flow from the manhole of our SSO. 3) Based calculations in spouting flow model on the three (3) observed spouts.	Estimated time of start of SSO: Based on when reporting staff (Water Worker bringing in drinking water samples) notified WQ. Backtrack his time to when he passed the location. End time based on observed cessation of flow from the manhole.  Last WQL employee arrived between 0845 and 0900 11/20/2023 and did not observe SSO occurring on Kansas Ave. at that time.

N	Cleaned Up (specify below), Contained All or Portion of Spill, Other Enforcement Agency Notified, Restored Flow		Spill response activities During: Containment berms were constructed at the primary SSO site. Straw wattles, dirt, gravel and sand bags, and road base material was used to construct the containment berms. SSO flow was reduced and controlled by placing sand and gravel bags upon the manhole openings. SSO was contained at the primary spill location. Fluid Resources Management (FRM), contract wastewater maintenance responded to SSO, sending a Vactor truck and staff to clear sewer main blockage. FRM cleared the blockage via the adjacent downstream manhole. During their efforts, a secondary SSO occurred at this manhole. FRM was able to recover most of the SSO using their Vactor. The remainder of the SSO flowed into the soil adjacent to the manhole. Sewage debris on roadway at the secondary SSO site was swept up and disposed. Post: Area was coned off, with sewage spill warning signs posted. Sewage debris was disposed and both SSO sites are scheduled for landscape assessment and remediation. 	Adjusted Schedule/Method of Preventive Maintenance		SSO Follow-up: Debris cleared from sewer main indicates that blockage occurred due to build up of FOG and physical debris in the sewer main. Users upstream of the SSO site are: 1) SLO County Animal Services; 2) Woods Humane Society; and 3) SLOC Honor Farm laundry and food preparation facilities. Plans are being made to update these facilities to FOG issues and BMPs to reduce their impacts on the collection system. Request to Wastewater Operations to inspect sewer main via CCTV to determine if further actions need to be undertaken.  	1. Scheduling with FOG program to provide education to users to reduce FOG disposal to collection system. 2. Scheduling with Wastewater Operations to CCTV sewer main.	20-NOV-23	Blockage of the sewer main was resolved on day of incident. Primary cause of SSO was determined to be FOG and debris clogging the sewer main. Blockage was cleared by jetting and vacuuming the sewer main using a Vactor.	N												N

We were unable to verify if the initial reporting party was present at the time the spill began, however, working backwards from staff recollections at 12:30pm (Sewer on-call staff) and 12:15pm (Water on-call staff) and from photos taken when the Sewer on-call staff arrived on site, we make a reasonable assumption that the spill began around at 11:50am and ended at 12:20pm.

Width of spill was contained between the sides of dwellings.	N						0	Unpaved Surface		Spill originated from a CCV BWPD under decking in a enclosed garbage storage closet located at 635 Main St. Due to the slope, the spill from the BWPD flowed over ground headed west towards 633 Main St. through a horizontal fence, over and down a wall down to a passageway over bricks and under decking pathway. The spill had ponded around passageway in front of entryway for 633 Main St. which contained a good portion of the spill. The Spill was contained along the side of 633 Main St. The Spill ponded to a point then breached a soil level at a higher elevation then proceeded to run downhill towards the rear of 633 Main St. where the spill stopped. In close proximity of the end point is a roof downspout drainage pipe underground. Undetermined at this point if the spill reached the drain. There was no obvious evidence and the soil didn't seem to be saturated. The flows witnessed in the USMH & DSMH were fairly consistent with minimal flow.

The crew encountered several joints within that distance that had  soft  root blockages. Once the blockages were broke, the crew checked the storm drain system and found that the spill had entered the first drainage inlet approximately 214' from the overflowing MH. They traced the spill through the downstream storm drain inlets. All the storm drain inlets were wet from previous rain. The storm drain system ultimately drains into the   Corte Madera creek. The crew then checked the upstream storm drain inlet and it was wet with storm water as well. The crew concluded that much of the water in the storm drain system had previously been there before the spill. The crew washed down the street recovering washdown volume and spilled sewage.   the downstream storm drain system was flowing from and staff was unable to capture lost spill volume.

The inspection revealed that the stoppage was caused by the presence of grease in the pipe segment. In order to resolve the issue, a thorough hydro-jetting process was carried out on the pipe segment to remove the accumulated grease and ensure smooth flow of the wastewater.		No ongoing investigation at this time. 	10-NOV-23														The Long Beach Health Department was notified and at the scene to supervise the cleanup of the contaminated area.	We have a 2-year Preventive Sewer Maintenance Program to ensure the long-term health and functionality of our sewer systems. This program involves regular inspections, proactive cleaning, and timely repairs to prevent blockages, backups, and other sewer-related issues.	We will proceed with our preventive maintenance program for this pipe segment and ensure that the cleaning is completed according to the schedule.	There is no planned rehabilitation or replacement of this segment.	CCTV inspections were conducted in order to identify the cause and precise location of the grease blockage. These inspections involved the use of specialized cameras to visually examine the affected area. Once the cause and location were determined, appropriate measures were taken to ensure a thorough cleaning of the blockage. The accumulated grease was meticulously removed from the system to restore its optimal functioning.	None planned.	No modifications have been made to the system or operating procedures. The pipe was inspected to determine the source of the grease, and this information will be used to target specific areas for FOG prevention in targeted advertising campaigns.

Time of call from City of Santa Cruz 911 emergency dispatch (Net Comm) was at 8:38 AM. City Staff were already mobilized in the field due to high winds and flooding. First responder Juan Molina arrived at 8:55 am and was met by several neighbors who confirmed a large Eucalyptus tree had fallen at 8:30 am, severing the 10'' aerial gravity sewer main. Spill end time is based on the mobilization of 3 combination units that continuously intercepted/vacuumed flow at the upstream manhole (City manhole identified as Q7-SM403) beginning at10 AM. City crews installed an air plug into the upstream manhole (City manhole identified as Q7-SM404) closest to the break and began installation of sanitary sewer bypass pumping system consisting of a 6'' Gorman Rupp diesel powered pump, 20 ft rigid suction intake hose, and 350' of lay flat discharge hose through Hagemann Gulch to manhole (City manhole identified as Q7-SM520) where gravity flow could resume.

Once flow rate is determined the the spill volume is derived by taking the time from SSO Start to End and multiplying it by the spill rate to get total volume of spill. 	EMWD relies on the individual or individuals who report the SSO for details about when the spill starts. Crews also make contact with property owners as well as involved parties when needed to help better determine when an SSO Started. Spill end time is when EMWD crews restore flow to the sewer system and SSO is stopped.

The methodology of the spill start time was based on supervisory control based on SCADA of the data collected on the Painter Street Pump station trend, and the rain gauge at the Wastewater treatment plant. We were prepared for the event and had sandbags, a ditch to convey the spill away from residential properties and signs posted.	Rainfall Exceeded Design, I and I (Separate Collection System Only)		Manhole		Other (specify below)	The failure is that the sanitary sewer main at this location was constructed with a 90 degree turn at this manhole and the earthquake in December of 2022 destroyed private laterals allowing more I&I to enter this portion of the sanitary sewer system. An upsizing project for this section of the sanitary sewer system is in the works since 2019 and will hopefully see some forward momentum with state funding this spring and summer, before the next wet season.	55	There was no impact to residence, or private property, or human life as spill response was already in place before the spill occurred due to the historic trend of this sight.

Sandbags were in place, signage was in place, property owners were notified and personnel frequently monitored at this site location. During and after spill the area was monitored to keep clean if there were any sewage debris. There were no debris that were noted. 	Plan Rehabilitation or Replacement of Sewer		This site has a planned upsizing project in the planning phases for the past 6 years. Currently waiting on State funding to push the design process forward. Also looking to camera sewer mains and do a smoke test of the laterals in the area that lead to the Painter Street Pump Station.	Meeting with the State Water Control Board and Engineering company GHD on January 24th, 2024, provided some comfort that the State would approve the funding of this project, and the City of Rio Dell can start the design process.	18-FEB-24	This SSO occurred due to the high levels of I&I. Several days of rain and saturation of the ground caused the pump station to become overwhelmed when large amount of rain occurred at once and caused the SSO at this location, the Painter Street manhole.	N			Eel River	River		The Eel River is a large river that runs north on the east side of the City of Rio Dell. There are no Surface Water users downstream of the SSO discharge location.

The methodology of the spill start time was based on supervisory control based on SCADA of the data collected on the Painter Street Pump station trend, and the rain gauge at the Wastewater treatment plant. We were prepared for the event and had sandbags, a ditch to convey the spill away from residential properties and signs posted.	Rainfall Exceeded Design, I and I (Separate Collection System Only)		Manhole		Other (specify below)	The failure is that the sanitary sewer main at this location was constructed with a 90 degree turn at this manhole and the earthquake in December of 2022 destroyed private laterals allowing more I&I to enter this portion of the sanitary sewer system. An upsizing project for this section of the sanitary sewer system is in the works since 2019 and will hopefully see some forward momentum with state funding this spring and summer, before the next wet season.	55	There was no impact to residence, or private property, or human life as spill response was already in place before the spill occurred due to the historic trend of this sight.

Sandbags were in place, signage was in place, property owners were notified and personnel frequently monitored at this site location. During and after spill the area was monitored to keep clean if there were any sewage debris. After the spill event, the ditch was cleaned, picked up of debris and sprayed with chlorine solution for disinfection.	Plan Rehabilitation or Replacement of Sewer		This site has a planned upsizing project in the planning phases for the past 6 years. Currently waiting on State funding to push the design process forward. Also looking to camera sewer mains and do a smoke test of the laterals in the area that lead to the Painter Street Pump Station.	Meeting with the State Water Control Board and Engineering company GHD on January 24th, 2024, provided some comfort that the State would approve the funding of this project, and the City of Rio Dell can start the design process.	01-FEB-24	This SSO occurred due to the high levels of I&I. The area received 3.84 inches of rain in 24 hours on 1/31/24 and into 2/1/24 the area received an additional 0.58 inches of rain. The atmospheric river saturated the ground and the system causing the pump station to become overwhelmed which caused the SSO at this location, the Painter Street manhole.

A smaller spill occurred in the home next door at 2538 Eaton Ave, Redwood City (37.484369240031995, -122.25825676483069) and was contained to a 3 ft x 3 ft shower pan with a 3 in lip.	37.484313138825	-122.25844571381	Inside Building or Structure, Lateral Clean Out (Private)		The resident at 2538 Eaton Ave heard gurgling in his primary dwelling plumbing. He notified the City 20 minutes later at 11:52am when he saw his shower pan begin to fill. This spill was contained to the shower pan which was 3 ft x 3 ft x 3 in. Another appearance point occurred next door at 2544 Eaton Ave out of a private cleanout in the front yard.	2760	The smaller spill was contained to the 2538 Eaton Ave shower pan, according to the property owner, who indicated the shower pan was 3 ft x 3 ft x 3 in. As this was on private property, we do not have any photos. The larger spill out of the private cleanout in the front yard of 2544 Eaton Ave spilled alongside the front of the primary dwelling towards 2538 Eaton Ave as there was a slight slope downward. The spill first continued into the backyard of 2544 Eaton Ave, pooling in the pathway and also spilled under the dividing wooden fence into the backyard of 2538 Eaton Ave.	N						2654	Building or Structure, Unpaved Surface	The private yards at 2538 and 2544 Eaton Ave had a combination of turf, wood chips, sand, pavers, and concrete.	The smaller spill was contained to the shower pan inside 2538 Eaton Ave. Please see Attachment 1. 2544 Eaton Ave Spill Area for an overview of the spill from the second appearance point.

An area-volume method was used to calculate the spill volume at the first appearance point, inside the shower pan. This volume was calculated to be 16.83 gallons. A duration and flow rate comparison method was used to calculate the spill volume of the second appearance point. Flow rate was determined by taking the average of 12 staff opinions of the flow rate, which was approximately 21.6 gallons per minute. Multiplied by the total spill time of 127 minutes, the volume of the second appearance point was calculated at 2743.2 gallons. Added together, the total spill volume is estimated at 2,760 gallons. 	The resident at 2538 Eaton Ave reports hearing gurgling noises in his shower plumbing 20 minutes before he saw clear water coming up inside the shower, at which time he called the City's Public Works Department main line to report the back up. Public Works took the call at 11:52am and dispatched staff at 11:55am. Based on the resident's observations, the spill start time is estimated as the time the resident observed the gurgling noise, at 11:32am. The spill end time was determined by on-site staff responding to the spill. Staff observed the spill ending from the cleanout appearance point at 13:39. 	Inappropriate Discharge to Collection System, Pipe Structural Problem/Failure - Controls	On the day of the spill, rain had been falling (see Attachment 2. Rainfall and rain rate Feb 7 2024), and staff found that 2544 Eaton Ave had illegally connected a French drain in front of the garage to the sewer lateral, which we can reasonably conclude contributed to the spill volume.	Gravity Mainline		Vitrified Clay		50	At the first appearance point, the spill was contained to the shower pan in a bathroom at 2538 Eaton Ave. The shower pan is described by the resident to be 3ft x 3ft with a 3in lip. Once the sewer main line was flushed, the spill went fully back into the collection system. At the second spill site, the spill spread to part of the front yard at 2544 Eaton Ave (wood mulch, pavers, and turf) and down a small slope into their side and part of the back yard (sand). The spill spread under the wooden dividing fence into the side and back yard of 2538 Eaton Ave (concrete and turf).	Y	Cleaned Up (specify below), Contained All or Portion of Spill, Property Owner Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		Initial response involved identifying the location of the sewer main blockage, and clearing the blockage using a vac-con jetting truck. The spill ended when staff flushed the main line on Eaton Ave and cleared the blockage. The spill occurred during a rainy day, and upon arrival staff found the spill to be clear water with no odor. The spill was contained to two private properties at 2544 and 2538 Eaton Ave and did not enter the street or any separate storm drainage systems. The spill in the backyard of 2544 Eaton was pumped out and put back into the collection system at the nearest manhole (in front of 2538 Eaton at the sidewalk). Hardscapes in both yards at 2544 and 2538 Eaton were broomed and washed down before disinfection. Affected mulch and a top layer of sand and gravel were scooped up from 2544 Eaton to be discarded.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause, Plan Rehabilitation or Replacement of Sewer		During the cleanup, staff found a French drain at 2544 Eaton connected to the private sewer lateral. The property owner has been notified and directed to correct the illegal discharge condition. Staff performed a CCTV inspection on 2/8/24 and identified a section of the main line in an area under a private fence post for repair. Staff have called for underground utilities to be marked and will be coordinating repair activities with the property owners. During the week of 2/12/24 staff returned to the neighborhood to flush the remaining sewer mains. 	2/8/24 nearby main lines were flushed and a CCTV inspection was performed on the main line. The property owner representative for 2544 Eaton Ave was contacted to correct the storm drainage tie-in. Staff placed a request for underground utilities to be marked, and staff is working to coordinate repairs with the property owners. 	07-FEB-24	The spill occurred during a day where rainfall amounted to 0.45 . Staff found the spill to be clear with no odor. The spill ended when staff flushed the City main line and removed a blockage. Staff discovered a private drain tied in to the sewer lateral during spill clean-up activities, and believe that the unauthorized stormwater connection contributed to the spill volume.

Assumed total volume based on comparative average flow data. Assumed constant discharge throughout duration. For spill volume estimation, used flow telemetry at the regional treatment plant (operated by Goleta Sanitary District) to determine when leak occurred based on drop in flow received. Calculated total volume received at treatment plant during this time period and compared to historical average flow during the same time period. Estimated volume that did not enter the tributary by measuring wetted areas around spill origin and calculated volume based on average depths of wetted areas. Recovered amount calculated by known capacity of equipment used to remove wastewater and debris.	Assumed spill start time based on analyzing flow telemetry and noting when flow received at regional treatment plant dropped off from normal.

Primary sludge pumping was stopped from the plant to allow repairs to be made. 55 feet of pipe were excavated and replaced. During the testing of the repair operations pressurized the line with recycled water and a new leak occurred causing a second spill which will have its own incident report. The recycled water was shut off and a new excavation and repair was performed. During this time, it was determined the entire pipeline needed to be taken out of service and a project was started to install valving at both the discharge plant and the receiving plant, which would allow operations to divert primary sludge into the waste activated sludge (WAS) line. This was completed as of 2/23 and the compromised primary sludge line has been taken out of service until further assessment can be made and a plan to address it has been formulated.	Engineering, Operations, and Asset Management departments are currently evaluating options to repair the line, reroute the line, or any other feasible alternatives. The plant is currently operating by pumping primary sludge overnight and switching to WAS pumping during the day.	21-FEB-24	Once the RP-5 primary sludge line was excavated, the line showed significant crown corrosion on the top of the line. This particular line had a few problems, which have now been discovered. There was no apparent cathodic protection to prevent corrosion and the soil is very wet due to the high water table in the area. The air vacs/reliefs were not properly operational, allowing gas and air to get trapped at high points along the line. The abrasive sludge wore out the glass lining thus exposing the pipe wall to hydrogen sulfide damage and corrosion. An inspection of the pipe was performed following a simliar incident in July 2022 and the contractor miscoded the observations and deposits attached when in reality there were large tubercles forming, a sign of corrosion.

Vacuuming the spill was started by the contractor at the end of the spill prior to entering the Ventura River, while the collections crew washed everything down to the vacuum truck. 	Plan Rehabilitation or Replacement of Sewer, Repaired Facilities or Replaced Defect	N/A	Approximately 100 feet of asbestos cement pipe were removed and replaced with plastic pipe (SDR-35). Two upstream line segments from the spill were rehabilitated with cured in place pipe lining, about 400 feet.   	We have evaluated all the ACP within OVSD�s sewerage system since the spill on 2/22. We replaced 100 LF of damaged 18in and 21in ACP immediately, beginning construction on 2/23/24. We rehabilitated 440 LF of poor condition 18in ACP on 3/4/24. We are in design now on the rehabilitation of approximately 3,500 LF of 18in and 21in ACP that we plan to bid this Spring and rehabilitate this Summer. We are also in design to rehabilitate the remaining 3,450 LF of 21in and 24in ACP in this trunk line. We intend to rehabilitate that portion in the Summer of 2025. Due to cost, we may have to split the work over 3-4 years instead of 2, but we are hoping to get competitive pricing to complete the work by the end of 2025. We have an additional 350 LF of 8in, 1,100 LF of 16in, 1,200 LF of 18in, and 1,450 LF of 21in ACP in our sewer system that appears to be in good condition. In the long term, we plan to rehabilitate with CIPP or burst with HDPE all remaining ACP within our system. 	04-MAR-24	After breaking stoppage with the combo truck Jetter, a damaged pipe with a visible void was discovered while CCTV'ing the district mainline, allowing debris, mud, and rock into the mainline and creating a stoppage.

The lift station first backflowed into the bathroom cleanout inside the nearest building. Personnel then placed a plug on the bathroom cleanout.   Shortly thereafter the lift station overflowed outside onto the pavement. Personnel were already at the scene when the lift station began to overflow and took immediate action to protect the downgradient storm drain. 	50	During the storm, the spill travelled from the lift station approx. 60 feet along a curb to a small 12-inch culvert, where it entered into SLAC�s storm drain system. The spill was promptly isolated with sandbags, but not before approx. 50 gallons had entered the culvert.   Because this event occurred after dark and it was raining, photos were limited. Attached are photos taken the next day. A map is also attached. 	Y	The spill entered at a 12� culvert, ID 34D-15. From 34D-15, stormwater is conveyed through a series of underground pipes that are routed through a hydrodynamic separator to remove sediments before the stormwater is released to the IR-6 drainage channel, which is about 1,800 feet south. 	0	0	This stormwater conveyance system daylights at the IR-6 drainage channel after traveling through a hydrodynamic separator to remove sediments. 	50	0	Drainage Conveyance System that discharges to surface water, Street/Curb and Gutter (2 3)		During the storm, the spill travelled from the lift station approx. 60 feet along a curb to a 12-inch culvert, where it entered into SLAC�s storm drain system.	Y	37.418431	-122.20156							04-FEB-24	The quantity that entered the storm drain system was estimated based upon a visual estimate of how fast the water was flowing out of the lift station and the amount of time the lift station had been overflowing before responders were able to isolate the spill. 	Timestamps from photos, calls, and texts sent during the event. 	Natural Disaster (specify below), Pump Station Failure - Power	A storm event caused the entire SLAC facility to lose power. Due to a repair in progress, rainwater seepage from a sump was siphoned into the lift station when the power went out. This created additional flow into the lift station, eventually leading to an overflow.   Personnel were already at the location and acted immediately to protect storm drains and isolate the flow. 	Pump Station - Power		Other (specify below)	The failure occurred at a lift station, not in a pipe. The lift station vault is made of wrapped steel. 	40	None	Y	Cleaned Up (specify below), Contained All or Portion of Spill, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		Responders were initially called to the area due to an indoor bathroom cleanout overflowing. They deployed an air plug in the bathroom cleanout and mopped up the bathroom floor. Shortly after the bathroom cleanout was plugged, the lift station began to overflow. Personnel immediately sandbagged off the storm drain inlet and utilized buckets to manually return water into the sanitary sewer.   Simultaneously, the responders were investigating why the lift station water levels continued to increase. They shortly discovered a siphon from the nearby sump under repair and were able to kink the hose to prevent additional rainwater seepage from entering the lift station.   An emergency generator was also deployed to restore power to the lift station in less than 30 minutes. 	Other (specify below)	Power was restored to the lift station in less than 30 minutes.   The pre-existing sump pump repair project that caused the siphon of rainwater seepage into the lift station was completed on 2/14. Should a power outage occur in the future, the sump water will not continue to flow into the lift station and will not cause the lift station to overflow. 	See 10a for description of corrective actions. See 10c for timeline of corrective actions. 	Power restored to lift station � 2/4/24 Repair on sump pump completed � 2/14/24 	04-FEB-24	The responders on site were able to identify the cause of the spill within minutes. No additional investigation was necessary.   The spill was caused by the combination of two events. First, a major storm caused the site to lose power, including the lift station. Second, a repair-in-progress at a sump that feeds into the lift station led to a siphon from a temporary hose. Under normal conditions, the sump would be pumped into the lift station and would not continue to fill the lift station during a loss of power.  	N			San Francisquito Creek	Stream		The spill entered at a 12� culvert, ID 34D-15. From 34D-15, stormwater is conveyed through a series of underground pipes that are routed through a hydrodynamic separator to remove sediments before the stormwater is released to the IR-6 drainage channel.   From the IR-6 drainage channel, stormwater eventually flows to San Francisquito Creek. San Francisquito Creek flows from west to east roughly parallel to the SLAC southern and eastern borders. Adjacent leaseholders separate SLAC property from the creek along SLAC�s entire boundary. At no place does SLAC discharge directly to the creek.	None	Other (specify below)	None	None	0	N	N

Y	37.24516	-121.93092							18-JAN-24	The SSO volume was estimated using a measurements of the spill boundary. The First Responder documented pictures of the spill area.  Dimensions of the spill boundary were estimated during the responding activities.  Most of the spill volume was contained, cleaned up, and returned to the collection system.  It was assumed that the portion of the spill was soaked into the unpaved driveway, backyard and front yard of the property. Portion of spill soaked to the ground and was unable to recover. For the soil saturation it was assumed to be 18% of the total soil volume using an approximate depth. The methodology used to estimate  the spill volume was measurements of the spill recorded by the first responder. Crew used tape measure and measuring wheel to measure the spill area.  These dimensions were used to estimate the spill volume. The total estimated spill volume and information from the reporting party (RP) were used to assume a reasonable start time.

N	Cleaned Up (specify below), Contained All or Portion of Spill, Mitigated Effects of Spill (specify below), Other Enforcement Agency Notified, Property Owner Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		Upon arrival, the responding City Crew immediately documented the extent of the spill with picture and video, and determined the location of the blockage in the collection system. All the spill was contained within the property and did not reach a storm drain conveyance system or waterway. Once the blockage was cleared and the spill stopped, the Crew began their cleanup efforts. The crew used portable pump and vacuum truck to recover the spill above ground. Next, the crew washed down the affected area and recovered the induced water. It was assumed the some of the spill was soaked into the land and was unrecoverable.  As a result, the crew place odor enzyme granules to reduce the spill impact on the property.	Enforcement action against Fats, Oil, and Grease (FOG) source, Inspected Sewer Using CCTV to Determine Cause		The City has planned the following corrective actions for this sanitary sewer overflow:  1. Re-video the plugged sanitary pipe segment along with the upstream and downstream segments in 6months. 2. Distribute grease flyers to the nearby residents. 3. Repair manhole monitoring device upstream of the collection system failure location.		19-JAN-24	While the Responding Crew cleared the blockage in the plugged sanitary mainline, the Crew documented their findings.  A pipe basket was used to collect grease that was removed while clearing the blockage within the mainline.  After conducting a follow up CCTV of the sanitary mainline pipe, there were no other major O&M observations or structural defects that may have contributed to the blockage. Therefore, it was determined that the cause was grease (FOG).		All investigation efforts concluded on 2/7/2024	07-FEB-24														NA	The City has planned the following O & M modifications to prevent the repeat of the spill event. 1.

The address of the main spill is 1571 MacArthur Blvd, however, sewage also seeped from 1545 and 1561 MacArthur Blvd. The public sewer is located within an easement on private property. During the initial 45 minutes of the response, the initial spill estimate of 150 gallons was based on the previous December 2023 spill volume. The Distirct's consultant had the previous calculation available, used the new flow width in the gutter to calculate a more accurate flow of 0.9 gpm.

Y	33.701843	-117.92838	33.6636	-117.94662					12-FEB-24	The spill volume was calculated by a civil engineer (District consultant) that took photos of the gutter flow width, measered longitudinal gutter slope, and calculated water depth, to calculate the flow rate of 0.9 GPM, for a total volume of 41 gallon over the 45 minute period that sewage entered the storm drain. All sewage was recovered by District field crews. The crew chased the storm drain flow until the pipe was dry. They inserted the vacuum tube and a second crew flushed the sewage to the downstream vacuum truck.   	The civil engineer used published flow equations, using the gutter slope, width of flow, water depth, gutter geometry. The flow start was reported by the affected property owners/tenants as the spill point was their floor drains and property cleanouts. The reported the spill immediately to the District inspector overseeing contractor work on the sewer pipe. The spill was relieved/stopped at 3:28 PM, as reported by District crews, see SSO Field Report form. 	Operator Error (specify below)	Contractor was removing calcium from the public sewer pipe as part of a large project.

Once the District inspector reported the SSO to the District, field crews were dispatched to the site, containment set up, and the vacuum process started. The District inspector ordered the contractor to remove the pillow plug, which releaved/stopped the SSO.	Other (specify below)	The District is reviewing the location for a level monitoring device. Also, a debrief with the inspector and contractor discuss the cause and specific situation and contributing factors associated with the manufactring plant. The District will add a flag to the GIS system notifying crews and/or future contractors of the batch process. The inspector has been directed to coordinate work and Manufacturing process discharge with the business.

Anaheim Street Long Beach CA	07-FEB-24	07-FEB-24	07-FEB-24			The spill originated at a Private 4  clean-out located in a parking garage.	33.78294	-118.14971	Lateral Clean Out (Private)			247	The spill began at a private 4  clean-out located in a parking garage and flowed down the garage floor into a private drain that leads to the street. It then moved down the street curb and gutter into a storm drain catch basin. Our on-call contractors, Ocean Blue Environmental, fully contained and recovered the spill at this location.	Y	The City of Long Beach's stormwater catch basin and conveyance system is a key component of the city's infrastructure. It is designed to collect and transport stormwater from city streets to prevent flooding. This catch basin is located at the curb of the road and acts as an entry point for stormwater into this system.	147				247	Building or Structure, Drainage Conveyance System, Paved Surface, Street/Curb and Gutter (2 3)		The spill impacted a parking garage as well as a catch basin managed by Long Beach Public Works. This basin is linked to a storm drain designed to gather runoff from Anaheim Street and channel it to other stormwater systems.	Y	33.78294	-118.14965							07-FEB-24	The spill volume was determined based on the Plumber's onsite information. According to him, the spill began at 9:00 am, releasing about 1 gallon per minute, and continued for 247 minutes until the crew cleared the blockage at 1:07 pm. This totals to approximately 247 gallons, which were all recovered by Ocean Blue.	Our crew spoke with the plumber, who noted the time the spill began. The spill ceased once the blockage in the lower lateral was cleared, restoring the flow.	Root Intrusion		Lower Lateral		Concrete		99	The spill temporarily altered the routine use of the parking garage and presented a potential challenge to the city's stormwater systems. Prompt action was required to manage and clean up the spill, a task that was effectively handled by Ocean Blue Environmental. While such incidents can have environmental implications and potentially inconvenience the public, it's important to note that all the spilled material was successfully recovered in this case, mitigating the overall impact.	N	Cleaned Up (specify below), Contained All or Portion of Spill, Property Owner Notified, Restored Flow, Returned All Spill to Sanitary Sewer System		The response team swiftly put containment measures into action by setting up barriers to halt the spill's spread.

Inspected Sewer Using CCTV to Determine Cause, Plan Rehabilitation or Replacement of Sewer		The sewer lateral has undergone thorough hydro-jetting and has been added to our repair list in accordance with our city's policy on tree root interference in laterals. We will maintain this lateral until repairs are scheduled in the future.		07-FEB-24	On 2/9/2024, a post-CCTV inspection was conducted to determine the cause of the sewer lateral stoppage. The inspection revealed that roots were the primary cause of the issue. Notes, video, and pictures were taken. The lateral was thoroughly hydro-jetted to clear the roots.		No ongoing investigation. 	09-FEB-24														The Long Beach Health Department was informed and arrived on the scene to oversee the complete recovery and cleanup of the contaminated area.	The sewer lateral has been added to our repair list and will be maintained upon request from the property owner.	The sewer lateral will be maintained each time a request is made to Long Beach Utilities dispatch.	The identified defect in the sewer lateral will be addressed through planned replacement as part of our ongoing commitment to maintaining the integrity of our sanitary sewer assets.	CCTV inspections were carried out to identify the cause, location, and structural damage of the lateral pipe on the city�s lower lateral. 	The necessary repair and maintenance work will be carried out by in-house sewer operations.	The sewer lateral has been added to our repair list and will be maintained upon the property owner's request until the repairs are completed. This process is in accordance with our established protocol for lateral repairs on the city side, which serves as an immediate system modification. 	We will continue following our spill response procedures on containment and clean-up efforts.	No ongoing investigation.

Because we have no record of any sewer issues occurring at this location in the past (other than storm related), we believe the spill occurred because of illegal dumping of storm water runoff into the sewer system. No blockage occurred; the spill was the result of the sewer pipe reaching full capacity. The sewer system could not handle the amount of rainwater being discharged into the sewer.  During dry weather, we have inspected the area for illegal storm water connections, to date we have not found any. 	33.03395	-117.27856	Manhole		None	7200	a portion of the spill entered a Storm Drain inlet approximately 70 feet North of the sewer MH 	Y	storm drain curb inlet.	3600	3600	Not available, the spill occurred because we encountered a larger than normal rain event. The City of Encinitas received approximately 3.13  of rain in a short period of time.  Normally, there are no issues with the sewer system at this location. Because we were having the huge amount of rain, WWC crews were doing a patrol of potential areas of concern. It was during this patrol the spill was discovered. During the record storm event occurring on April 10, 2020, we had a similar issue. Because there are no records of any sewer issues at this location in the past(other than storm related), we believe the spill occurred as the result of illegal dumping of storm drain runoff into the sewer system.  	3600	3600	Drainage Conveyance System, Surface Water, Unpaved Surface		There was NO sewer blockage found. The spill occurred because of a very large rain event. We believe homeowners were opening their sewer clean outs and allowing water to go into the sewer system, so they could prevent their property from flood damage. The sewer system reached full capacity and we began to vacuum the water from the MH. In the picture, you will notice there are no signs of a sewer spill, no TP, Feces or other debris came out of the MH. Also, when the rain stopped, the sewer overflow stopped too.  We estimate 7,200 gallons came out of the MH, by vacuuming the water from the MH, we prevented 3,600 from entering the storm drain system.. Total estimated spill volume to the storm drain system was 3,600 Gallons. This 3,600 gallons went into the storm drain, mixed with millions of gallons of rainwater and went to the Ocean several miles west of the spill location.  	Y	33.03395	-117.27856							22-JAN-24	Because we had a similar size rain event occurring in April of 2020, we were doing a patrol of potential flooding sites. During this patrol, our crew found the MH just before it started overflowing (because they checked the water level in the MH). They observed the water level was getting high, so they called in the crew with the combination sewer cleaner. The combination cleaner crew arrived within 10 minutes and began to vacuum just after the MH started to overflow. We used the SSCSC Manhole overflow spill gauge. to estimate the volume.	Actual times the patrol crew arrived on-sight and the time the combination cleaner crew arrived on-site and the time the MH started to overflow.	Rainfall Exceeded Design, I and I (Separate Collection System Only)	We have CCTV inspected the sewer pipe, there were no problems found. We do not feel there are any issues with the sewer pipe. The stormwater entered the sewer system because property owners removed their sewer clean out caps and allowed rainwater to enter the sewer system. They did this to prevent property damage caused by rain/flooding. 	Gravity Mainline		Vitrified Clay		40	We do not feel there was any impact because of this spill. The 3,600 gallons of water that entered the storm drain system, mixed with Millions of gallons of rainwater and was diluted.  	Y	Contained All or Portion of Spill, Returned Portion of Spill to Sanitary Sewer System		Please see #3 above. Because of a similar size rain event occurred on April 10, 2020, we were doing a patrol of potential. areas with possible flooding. The patrol crew found the sewer MH before it started to spill, but noticed the water level raising in the MH, so they called in the combination sewer cleaning crew to start vacuuming the spill. The vacuuming crew arrived just after the MH began to overflow. Crews remained on-sight vacuuming for approximately 60 minutes.   	Other (specify below)	We plan on doing some smoke testing to see if someone has connected a storm drain pipe to our sewer system. Also, plan on doing a patrol again of the area during all rain events to try and catch someone draining their property. 	We will perform smoke testing of the sewer system to determine if someone has illegally connected a storm drain pipe to our sewer system.  	Will perform patrol during every rain event and schedule smoke testing during the summer months.	22-JAN-24	Spill was related to the storm event. The rain got very intense, because of the amount of rain, we patrolled areas of past flooding conditions. During this patrol, we found the sewer MH on Loch Lamond before it was spilling. Vacuum truck crews arrived on-sight and began to recover the spill water. the crew vacuumed for approximately 60 minutes. The rain started to slow down and the MH stopped overflowing.

Onsite, the dimensions of the spill, including its length, width, and depth, were measured and recorded. 	The spill's start was determined based on the data, information, and observations provided by the neighbor and homeowner through interviews.

The inspector examined both upstream (L2-262) and downstream (L2-257) manholes and discovered that sewer was being held in one of the manholes. Subsequently, the inspector reached out to a contractor to clear the blockage at the mainline and restore the flow. Meanwhile, another contractor was arranged to inspect the laterals and removed blockages. Cleanup efforts included washing down the sidewalk and ensuring that all wash down returned to the sewer system through the PLCO.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause		All blockages were cleared, and a test run was conducted to ensure flow was restored on-site. Cutters were run at lower laterals to confirm they were cleaned and free of blockages. The spill was cleaned up using a wash down method. The district plans to return in 6 months to evaluate the root situation and assess the condition of the mainlines, laterals, and manholes before proceeding with further modifications.		20-FEB-24	The investigation determined that the spill occurred on the sidewalk of the property located at 10116 Pardo Vista Dr. due to the absence of a capped PLCO and backflow device at this property. Consequently, when the sewer backed up due to a blockage caused by root intrusion in the lateral and in the mainline at 22620 Stevens Creek Blvd, resulted in the spill at the cleanout.		none	20-FEB-24														None.

From the curb/gutter, the sewage eventually reached and entered a nearby storm drain system inlet. This storm inlet is connected to the City of San Jose's municipal storm sewer system. The sewage then traveled within the storm system to a storm drain outfall and discharged to Ruby Creek.

The second inlet (#5280) along Vista Verde Dr was approximately 506 ft from the spill appearance point. Both storm drain inlets are connected to the same storm drain sewer system which flows south along Vista Verde Dr.  The sewage traveled within the storm system to a storm outfall discharge point along Ruby Creek. The responding Crew observed existing flow in the storm drain conveyance system from a recent rain event that occurred on 3/29/2024 and 3/30/2024. This existing stormwater flow mixed with the spill (sewage) and was diluted in the storm drain conveyance system. Pictures of the spill entering and within the storm drain conveyance system are uploaded as attachments. In addition to the pictures, a map of the spill path within the storm drain conveyance system is also included. 	0	3622	It was assumed that sewage reached Ruby Creek by discharging from a storm drain system outfall. The longitude and latitude location of the storm outfall along the Ruby Creek is approximately at 37.33790991437537,-121.80315400022855.

An assumed spill start time was estimated by gathering information from the reporting party. To determine the portion of spill which contained on land, the Crew used approximate measurements to estimate the recovered volume. All of the spill that reached the separate storm drain system was assumed to have been lost to the waterway due to the recent rain on 3/29/2024 and 3/30/2024. Rain from the previous days had introduced stormwater into the MS4 that continued to flow in the system on 4/1/2024. As a result, the spill that entered the storm drain conveyance system mixed with the existing stormwater flow.	The reporting party first noticed the spill on 4/1/2024 at 10:30. At that time, the reporting party stated that the spill had already reached a nearby storm drain inlet. As a result, the SSO started some time that morning before the reporting party first noticed. Upon arrival to the spill, the responding Crew observed that there were not many tire marks or stains from cars passing through the spill area. The lack of car tire marks meant that the spill had not been going on for a long period of time. Combing the available information and high visibility of the spill appearance point, it was then assumed that the spill likely started within an hour of the reporting party first noticing the spill. The start time of the SSO was assumed to have started around 09:30 on 4/1/2024.	Fats, Oil and Grease (FOG)		Gravity Mainline		Vitrified Clay		60	The spill required cleanup of the street, curb and gutter near Vista Verde Dr and Cuesta Dr. In addition, it was assumed that raw sewage reached Ruby Creek. Based on the responding Crew's visual observations, there was no adverse impact to the environment or wildlife at the time of the spill. The City of San Jose Environment Department conducted a creek walk to assess the impact to the waterway on 4/3/2024. The result of the creek walk also showed no impact to the creek or wildlife. 	N	Cleaned Up (specify below), Contained All or Portion of Spill, Mitigated Effects of Spill (specify below), Other Enforcement Agency Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System		Upon arrival, the responding City Crew immediately placed sandbags around the nearby storm drain inlets where the spill had entered. The Crew tracked the spill in the storm drain conveyance system (MS4). It was assumed that that the spill discharged out from a storm drain outfall into Ruby Creek. Once the blockage was cleared and the spill stopped, the Crew began their cleanup efforts. At the spill source point, a Crew flushed sewage from the asphalt and curb to the nearby storm drain inlet. Water was used from a nearby hydrant and Vacuum truck to clean all of the spill on land. A second Vacuum truck was positioned at the affected inlet to recover the spill on land and induced water. All of the spill that reached the separate storm drain system was assumed to have been lost to the waterway due to the recent rain on 3/29/2024 and 3/30/2024. Rain from the previous days had introduced stormwater into the MS4 that continued to flow in the system on 4/1/2024 during the spill event.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause, Plan Rehabilitation or Replacement of Sewer		The City has planned the following corrective actions for this sanitary sewer overflow:  1. Adjust the plugged pipe segment operation and maintenance cleaning frequency from 1 years to 6 months. 2. Re-video the plugged sanitary pipe segment along with the upstream and downstream segments in 6 months prior to cleaning. 3. Request Public Works rehabilitation project to address mainline pipe sags which likely contributed to grease/debris settling in the pipes. 4. Distribute grease (FOG) outreach flyers to nearby residents.	The City has scheduled following corrective actions for this sanitary sewer overflow:  1.

A pipe basket was used to collect grease, rags, and debris.  After conducting a follow up CCTV of the sanitary mainline pipe, there was evidence of severe grease deposits that were present in the mainline pipe where the blockage was located. Other than that, there were no other major O&M observations or structural defects that may have contributed to the blockage. Therefore, it was determined that the cause was grease (FOG).

Upon investigation, it was found that the double barrel 6  siphons, situated at the end of Gainsborough Rd. and running through the park, were obstructed beneath the storm drain conveyance system. The backed-up flow had entered the old existing 10  main as intended for backup. The 10  main also backed up at its siphon due to grease buildup. Flow then surfaced at the manhole structure along the walking path for the backup 10  main. This overflow then spread to Combes Avenue and the storm drain conveyance system through multiple entry points. For detailed location and spread information, please consult the attached GIS map and photos in attachments. At 11:25 A.M., staff successfully cleared the 10  siphon, restoring normal flow conditions to the backup sewer main. Following this, both 6  siphons were cleared to regulate flow, consequently deactivating the backup 10  sewer main.	Y	34.18785	118.8658							13-APR-24	The methodology used was estimating SSO flow out of manhole cover in place. The flow from the cover was observed to be approximately 2 1/2 to 3 inches. We opted for the higher end of the estimate, around 3 inches, equating to 54 gallons per minute (gpm). This rate was then multiplied by the duration from when we were first notified of the spill.	The estimated start time of the spill was identified as the moment the operator received the phone call at 9:49 A.M. Subsequently, the end time of the spill was established at 11:25 A.M., when operators cleared the 10  siphon and flow stopped surfacing.

Operators strategically placed sandbags around entry points of the storm drain conveyance system while utilizing the hydro combination truck to clear grease buildup from the siphons. Following this City staff proceeded to vacuum the accumulated sewage on Combes Avenue, cleanse the walking path and street, and clear debris from the storm drain inlet. Unfortunately, due to inclement weather and accessibility constraints, cleaning of the large open concrete storm drain system was not feasible. 	Adjusted Schedule/Method of Preventive Maintenance	Moved all siphons at location to a monthly cleaning schedule. 	Cleaned siphon's thoroughly. Could not inspect siphon's with CCTV equipment. Moving cleaning to a 1-month schedule to clear FOG more regularly. 	May 1, 2024, start cleaning siphons on a 1- month schedule. 	13-APR-24	During the hydro cleaning process of the 6  siphons and the backup 10  siphon/sewer main, grease buildup was identified. Once the 10  siphon was cleared of grease, it resumed flowing, followed by clearing of the 6  siphons, resulting in the restoration of normal flow conditions through the double barrel 6  siphons. Upon reviewing the cleaning schedule, it was observed that the 6  siphons were last cleaned on January 23, 2024, while the backup 10  siphon was cleaned on March 14, 2017. Unfortunately, conducting a CCTV inspection of the siphons to capture footage was not feasible. Consequently, it has been decided to transition both the 6  and 10  siphons to a monthly cleaning schedule.	N	N/A	15-APR-24	Lang Creek and Arroyo Conejo	Other (specify below)	Natural creek/waterway.

Flow headed west and into the tributary spread across 145 linear feet of the embankment. Flow spread around the spill origin covering roughly 50 foot diameter circle area. Spill also headed south along the eastern edge of the service road in a 10 foot wide stream, then east along the northern edge of the service road where it pooled on the north side of the service road and created a triangular shaped wetted area.

Flow also crossed over service road to the south and pooled in a drainage area. See attached spill map. The spill origin is 30 feet from tributary of Tecolotito Creek, 1,000 linear feet from main body of Tecolotito Creek. Roughly 6,000 linear feet from location of spill entering the tributary to Goleta Slough inlet at Pacific Ocean if travelling along the waterway. Tributary had existing flowing water in it at time of spill.

Assumed total volume based on comparative average flow data. Assumed constant discharge throughout duration. For spill volume estimation, used flow telemetry at the regional treatment plant (operated by Goleta Sanitary District) to determine when leak occurred based on drop in flow received. Calculated total volume received at treatment plant during this time period and compared to historical average flow during the same time period. Estimated volume that did not enter the tributary by measuring wetted areas around spill origin and calculated volume based on average depths of wetted areas. Recovered amount calculated by known capacity of equipment used to remove wastewater and debris.	Assumed spill start time based on analyzing flow telemetry and noting when flow received at regional treatment plant dropped off from normal. Spill stop time determined by field observation of when water stopped coming out of ground after all valves were closed and pipe was isolated.	Other (specify below)	See attachment for #4.a.	Force Main		Ductile Iron		46	Current estimates are approximately 1,089,000 gallons of raw wastewater spilled from site. Roughly 66,500 gallons were contained within non-native dominated grassy area, of which 17,000 gallons were recovered and disposed of at the treatment plant. 1,022,500 gallons are believed to have entered a tributary to Tecolotito Creek which eventually drains to the Pacific Ocean. Approximately a day and a half into response activities, spill area received approximately 3 inches of rain. Site monitoring is ongoing.

Procedure to reintroduce service to 24  forcemain on Friday February 16 was followed. Hole was roughly 6� in diameter with a 5� crack running from the hole along the side of the pipe. Expected life expectancy of pipe is 60 to 100 years and pipe age is 46 years.  Pipe section retained for investigation.  During excavation and replacement of portion of failed pipe, remaining pipe visually inspected with no issues seen.  Flow data also under analysis.

Tributary joins Tecolotito Creek upstream of confluence with other creeks at Goleta Slough mouth to Pacific Ocean.  Multiple uses for water bodies defined in Basin Plan.	Staff has been monitoring tributary, Tecolotito Creek, and Goleta Slough multiple times on day of spill and subsequent weeks after, including 2/17, 2/18, 2/20 through 2/23, and 2/27 through 3/1. This was done during water sampling activities as well as other site visits specifically to observe the waterway and aquatic life. No apparent impacts on aquatic life observed.  Monitoring ongoing, and in communication with California Public Health Department.	Other (specify below), Public Closure	GWSD is aware of a Beach Advisory being issued by the local public health department on 2/16, before the date of the spill, because of the anticipated water quality impacts as a result of the forecasted storm event on 2/18 and 2/19. GWSD monitored whether the Goleta Beach area was closed and followed up to confirm. GWSD reached out to the local public health department on Wednesday, 2/21 and understands the beach was then closed on that day. GWSD was told by County staff on 2/25 that the beach was closed due to unrelated dredging and beach replenishment activities in the Goleta Slough by Santa Barbara County Flood Control District that started on 2/20.  Beach remains closed and signs posted for health advisory.	Santa Barbara County Public Health Department and Environmental Health Services	10	N	Y	Water samples were taken from 4 separate locations within the receiving tributary and downstream in Tecolotito Creek on 2/17 in the afternoon. Upstream from the discharge point, at the discharge point, and two downstream of the discharge point where water is fully mixed with receiving water. Additional samples were taken upstream of the contact point and below for reference. Samples were taken at sample sites 1 through 4 between 3:30PM and 4:00PM on 2/17/24. Sample site 4 was replaced by sample site 5 & 6 during the next sampling period on 2/22/24. Sample sites 1, 2, 3, 5 & 6 were sampled again on 2/27 and 2/29/24. Refer to sample location map for specific locations.  GWSD understands samples are also being collected by other local agencies including local health department.	All samples were analyzed for total and fecal coliform and ammonia.  GWSD is consulting with other agencies, plans including Ocean Plan, and continuing to sample post-spill conditions until further guidance.									GWSD will continue further investigation of incident alongside the broader assessment of forcemains for future rehabilitation or replacement with contracted engineering firm that has already begun to ensure incident does not occur again.

It was assumed that a typical diurnal residential flow pattern experiences a maxim flow rate from 6:00 to 12:00, 75% of the max flow from 12:00 to 18:00, 65% of the max flow from 18:00 to 24:00, and 15% of the max flow from 24:00 to 6:00. A total spill volume was estimated using this diurnal flow pattern and an approximate duration of the spill. For the spill on land, the Crew used approximate measurements to estimate the recovered volume. For the spill recovered from the storm drain system, an approximate depth of flow was measured while tracking the spill. The depth was applied to a partially filled cylinder calculation to estimate a volume for each of the storm drain pipes. The spill recovered from the MS4 was negligible (less than a gallon). 	The reporting party first noticed the spill on 4/10/2024 at 07:00. At that time, the reporting party stated that the spill had already reached the nearby storm drain inlet. Based on the reporting party's information and high visibility of the SSO appearance point, it was assumed that the SSO likely started shortly before the reporting party noticed the morning of 4/10/2024. The start time of the SSO is assumed to have started around 06:00 on 4/10/2024 when there is a typical peak flow for residential areas.

The Crew tracked the spill in the storm drain conveyance system (MS4). The responding City Crew placed sandbags in the furthest downstream manhole prior to the discharge point to the waterway. It was confirmed that that the spill discharged out from a storm drain outfall into San Tomas Aquino Creek. Once the blockage was cleared and the spill stopped, the Crew began their cleanup efforts. At the spill source point, a Crew flushed sewage from the asphalt and curb to the nearby storm drain inlet. Water was used from a nearby hydrant and Vacuum truck to clean all of the spill on land. A second Vacuum truck was positioned at the affected inlet to recover the spill on land and induced water. Most of the spill that reached the separate storm drain system was assumed to have been lost to the waterway due to the duration and proximity of the SSO.

Replacing upstream cleanout with manhole to assist with sewer main preventative cleaning. Staff has added this area to their hot spot areas. 		27-FEB-24	We believe the spill originated from upstream private onsite sewer maintenance that discharged are larger than normal amount of debris, rags, wipes, etc. to the sewer main. This led to the blockage in the main which caused the sewage to overflow from the manhole at Ellesmere Drive and Newgate Way. We were led to this conclusion due to a private sewer lateral discharge that occurred on March 10, 2024, shortly after this spill, from the Meadowood Village apartment complex that is immediately upstream of this spill location. Notably, the location of this spill is near the upstream most part of this sewer main segment and the Meadowood Village apartments is one of the main contributors to the flow in this upstream segment. After this spill and subsequent private lateral sewage discharge, staff routinely monitored this sewer main for the rest of March. During the past month, there were no further issues with this sewer main area and no further spills. 		N/A.	28-MAR-24														N/A.

The initial call was reported as a water main leak. The only water visible was within the sinkhole but there was moisture along the  gutter.  After  further  inspection,  City staff took samples of the water which were in inconclusive. Additional staff was called out to test the Lift Station operation. Staff turned on one pump @ 100% speed with no visible water flowing out of the system. Staff then turned-on a second pump @ 100% speed, then shortly after, sewage was flowing out of the cracked concrete in sidewalk. Staff then proceeded to isolate the force main in operation and use a redundant force main to re-direct sewer flows. The spill was contained within the gutter. A visual inspection was done on the private storm drain which was dry, and no evidence of sewage was detected.	38.36877	-121.93401	Other (specify below)	The spill first appeared through the concrete sidewalk and back of sidewalk after causing underground erosion which also formed a sinkhole underneath the pavement adjacent to the curb and gutter.

At spill appearance point 1, the spill left the system and entered the street curb and gutter, with approximately 298 gallons contained on the street. Two gallons entered the conveyance system located on Ocean Blvd, and all 300 gallons were recovered by Ocean Blue Environmental. The remaining 208 gallons traveled down the sidewalk and entered the Bayshore beach.	Y	33.75324	-118.13089							02-APR-24	Upon arrival, sewage was actively overflowing from City Sewer Manhole Q04-SMH-065 at a rate of approximately 2.7 gallons per minute (GPM). The total spill volume was calculated by multiplying the flow rate by the overflow duration, resulting in 2.7 GPM x 80 minutes = 216 gallons.  The affected areas on the curb, street, gutter, and sidewalk were estimated using the formula for volume: Length x Width x Depth.  For the first location, the dimensions were 245 ft x 1 ft x 0.0625 ft, resulting in a volume of 15.31 cubic feet or approximately 114.53 gallons. For the second location, with dimensions of 35 ft x 0.5 ft x 0.0208 ft, the volume was approximately 0.36 cubic feet or 2.72 gallons. The last area, near the LACFCD, measured 14 ft x 80 ft x 0.0208 ft, with a volume of 23.3 cubic feet or 174.25 gallons.  The total spill volume across all areas was approximately 508 gallons.

Ocean Blue conducted a clean-up and successfully recovered the spill. Two gallons entered the conveyance system on Ocean Blvd but were also contained and recovered. Despite these efforts, 208 gallons entered Bayshore Beach, possibly impacting marine life and water quality. In total, 300 gallons were accounted for and recovered.

Spill Containment:     - At spill appearance point 1, where approximately 298 gallons of sewage spilled onto the street, containment measures were implemented to prevent further spread. Barriers were deployed to contain the spill within the affected area.     - For the 2 gallons that entered the conveyance system on Ocean Blvd, containment measures were also implemented. 2. Cleanup Efforts:     - Ocean Blue Environmental immediately initiated cleanup operations for the spill on the street. The 298 gallons of sewage were promptly cleaned up using pressure washers and a vacuum truck.     - Cleanup activities were conducted to address the two gallons of sewage that entered the conveyance system. Ocean Blue Environmental used a vacuum truck to flush the system and remove both sewage and nuisance water.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause, Other (specify below)	A SmartCover will be installed at this location to monitor and prevent future spills, given its proximity to the bay.	1. The mainline segment was thoroughly hydro-jetted. 2. The preventive maintenance schedule was adjusted. The mainline segment has been added to our hot spot list for more frequent cleaning. 3. A Smart Cover Electronic Device will be installed under a City Sewer Manhole. This device monitors water flow and sends an alarm to LBUD when significant changes occur, serving as a warning of an impending spill.  We commit to maintaining proper cleaning practices by our staff.	The significant milestone for the corrective action includes the pipeline CCTV Inspections, completed on 4/3/2024. The pipeline inspection aims to evaluate the sewer system's condition and identify any potential problems or blockages.  We have arranged with All American Asphalt to install a new ring and cover. This will enable SmartCover to install their device on the lid. The work is anticipated to be completed by the start of July.	02-APR-24	A CCTV investigation into the spill's cause revealed a heavy presence of sand in the system. This unusual sand accumulation significantly contributed to the blockage that resulted in the spill. It is speculated that it may have entered the system through manhole vent holes from stormwater runoff and a LACFCD stormwater pump station that could bring sand in with the clearwater.	N			Bayshore Beach	Ocean		Bayshore Beach is located on the south western shore of Alamitos Bay, near the Belmont Shore, Naples, and Peninsula neighborhoods of Long Beach. Bay Shore is separated from the open ocean by the Alamitos Peninsula, ensuring calm, tranquil waters year-round, ideal for swimming and all types of water-based recreation. Bay Shore is a popular summer destination spot for families and people looking to stay active while enjoying the Southern California sun, as it offers a wide range of activities and recreational amenities for all ages.	No visual impact on aquatic life was noted during the investigation and assessment of the sewer spill.

At the time the first responder arrived at 11:42am, photos show a small spill rate (1gpm) from one of the two small holes in the lamp hole lid, so the spill flow was intermittent. Based on the resident's photo submission, we estimate the spill was already at 5-6 gallons on the street, and therefore estimate the spill start time at 11:21am given a 1gpm flow rate and allowing 2 minutes for the resident to submit a notification through our online portal. The average flow rate is estimated at 1gpm, as the spill coming out of the cover was intermittent, and the existing spill area was not deep nor large in area. At the time the spill ended at 12:07pm, 46 minutes had passed. With an average flow rate of 1gpm, 46 gallons were spilled.	This intersection is highly trafficked throughout the day as it is alongside El Camino Real, and it is realistic that a person noticed the spill very soon after the spill had started. The photo submittal also shows the small area affected, as well as the source of the spill which did not show any flow. The photo taken by staff on site shows a very slow spill rate. The spill end time is based on the time the crew relieved the main line blockage and no further spill exited the lamp hole cover.

Once the flow was restored in the sewer main and the spill stopped, the spill was cleaned up. The street was washed and disinfected and all wash waters were also collected and disposed of.	Adjusted Schedule/Method of Preventive Maintenance																							This section of the City sewer main was flushed again the following day to ensure no continuing blockage.

The crew removed the blockage, and the backup ceased at 9:08 PM. The cause of the blockage was attributed to debris accumulation. All necessary clean-up was then performed.  It was estimated that approximately 40 gallons of sewage backed out of the sewer as a result of the blockage. The crew was able to establish partial containment, and was able to recover 16 gallons of sewage. The remaining 24 gallons of sewage entered an adjacent County of Los Angeles owned catch basin at 21154 South La Salle Avenue, which is tributary to the Dominguez Channel.

Per the R/P it gradually increased to a height between 1 to 2  during his observation but then walked away after calling dispatch. First responder arrived at 1230PM and witnessed minimal liquid seeping out of the manhole. Second responder arrived with the Jetter truck and broke the blockage at 1254pm. Based on what the R/P witnessed and the steep slope of the road and the estimated distance that the flow traveled down the street I have elected to say that the spill started just before he saw it at 1204 which would put it at 1156am. I also believe that it didn't continue to spill the full duration since it was not spilling much when first responder arrived and there are only four homes connected upstream of blockage and there is a break over manhole upstream. I'm also electing to say that it spilled for 15 min. out of 1/2 pry hole.

Inspected Sewer Using CCTV to Determine Cause																							Sanitary Sewers: Sanitary sewers carry wastewater from homes and businesses to wastewater treatment plants. They consist of pipes or �laterals� that are attached to homes, businesses and other buildings, main sewer lines that transport wastewater from the laterals to wastewater treatment plants (sometimes called water reclamation facilities), pump stations that help move the sewage through the pipes where gravity doesn�t do the trick, manholes that provide access to the pipes, and finally, the wastewater treatment facilities themselves, where wastewater is cleaned before it is released it back into the environment. The role of sanitary sewer systems is to get that wastewater to treatment plants without it leaking from the pipes or overflowing from manholes (a Sanitary Sewer Overflow or SSO). Leaks and SSOs can both contaminate groundwater and nearby water sources. Sanitary sewer systems also must be maintained to prevent Inflow and Infiltration (I&I), whi

Once the sewage exited the grass, it continued over the sidewalk and collected in the gutter. From there, it made its way into the storm drain where it was contained in multiple drain sumps. The sewage did not exit the storm drain which day lights at a percolation basin. The storm drain was jetted and all water and sewage were removed with the District's vac truck.  	Y	The sewage entered the storm drain and was contained in multiple sumps within the storm drain system. This prevented the sewage from daylighting at the percolation basin. All sumps containing sewage were cleaned with the vac truck. All affected piping was thoroughly jetted with all water/sewage also being removed with the vac truck. 	105				211	Drainage Conveyance System, Street/Curb and Gutter (2 3), Unpaved Surface		The spill originated from two 1in manhole pick holes. The sewage continued to flow from the manhole located in a lawn, over the sidewalk at an approximate spill rate of 2.5gpm from each pick hole, collecting into the gutter. Once the sewage collected in the gutter made its way into the storm drain, it was further contained in multiple sumps within the storm drain system. All sewage was contained within the storm drain system and did not daylight at the percolation basis.  	Y	36.63942	-121.82493							16-MAR-24	The start time was determined by speaking with the reporting party as well as a neighbor who also witnessed the spill. Capturing the spill height and number of spill points from the manhole cover also helped with approximating the spill rate. The total measured spill path from the start to the end point was also captured and included in the total spill volume recovered except for the volume within the grass/dirt area.    2.5 gpm + 2.5 gpm x 60 min = total spill of 300gal.   total measured area from sidewalk, gutter storm drain sumps and pipe =211 gal.  300-211 = 89 gal of unrecovered sewage. 	The start time was determined by speaking with the reporting party as well as a neighbor who also witnessed the spill. Calculating the spill rate to include the full spill path was also used to help determine the start time. 	Fats, Oil and Grease (FOG), Root Intrusion		Gravity Mainline		Vitrified Clay		45	The spill originated from two 1in manhole pick holes with each having a flow rate of 2.5 gpm. The sewage continued to flow over the sidewalk collecting in the gutter and making its way into the storm drain. Once in the storm drain, it continued to collect in each of the 6 sumps which help to contain and prevent the sewage from daylighting at the percolation basin. All sewage within the storm drain, gutter and sidewalk was recovered. 	N	Cleaned Up (specify below), Contained All or Portion of Spill, Restored Flow		Spill response consisted of documentation of the spill rate exiting the appearance point. Next the focus shifted to containment which was achieved by utilizing dirt to create a berm and prevent any further sewage from entering the storm drain. The full spill path was identified, and the cleanup consisted of recovering all sewage from the storm drain and gutter with the use of the vac truck. The storm drain was then jetted with the vac truck to allow for the recapture of all water used during the cleaning.   Wash down of the sidewalk and gutter area consisted of lightly misting cl2 and washing down with clean water from the Jetter truck. All water used for cleanup was directed to the Vactor which was positioned to allow for complete vac removal of all cleanup water used.  	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause		The sewer main was thoroughly inspected with the Districts CCTV unit. The cause of the spill was found to be root intrusion and FOG build up. To address these issues, the maintenance frequency has been increased to help break up any possible future build up. Also, the length of main required to be addressed during these maintenance intervals has been increased to the include the full length of main up to the newly constructed system. 		16-MAR-24	The sewer main was inspected by utilizing the District CCTV unit. This allowed for a full evaluation of the main to help determine the cause of the spill. The inspection identified root intrusion as well as FOG build up to be the cause. While the camera was still conducting its inspection, the main was thoroughly jetted to ensure all roots/FOG had been removed. 		The line was televised through the use of the CCTV unit, the cause was found to be root intrusion and FOG buildup.  The line will be CCTV'd again in 6 months for a follow-up inspection. 	18-MAR-24														N/A	The maintenance frequency for this location has been adjusted.

N	Cleaned Up (specify below), Contained All or Portion of Spill, Mitigated Effects of Spill (specify below)		Upon discovery of the spill, the building manager and the Operations and Maintenance team closed off the restrooms to stop the toilet overflow. Coordination with vendor/third party contractor took place to ensure the line was cleared/unclogged within a 2 hour time period. Third party contractor (Service Master) was dispatched to have the black water cleaned up and areas sanitized. Additionally, the Operations and Maintenance team ensured to place a sorbent sock around the storm drains to prevent spill from going into the storm drains. Some of the sanitary sewer spill made its way into the storm drain that is located outside of the ACS building, but Applegate Teeples hydro jetted the storm drain and captured the rinsate. 	Adjusted Schedule/Method of Preventive Maintenance		Frequency of pipe flushing/jetting has increased, along with an increased frequency of inspections at sanitary sewer manholes across campus. In the future, Operations and Maintenance team may implement a more frequent sanitary sewer line flushing to prevent future spills. 		04-MAR-24	Overflow from the toilet in the basement of the ACS building was observed, which prompted the shut down of the restrooms in the building. Manholes on the east side of the ACS building also spilled sewage, since they were associated with the same sewer line as the toilet. Investigation conducted by the Operations and Maintenance team and Applegate Teeples indicated that the spill was caused by a clogged sewer line that ran through through the southwest side of the ACS building. It was determined that the clogged was caused by non-flushable/non-disposable wipes that had been flushed down the toilets.

The WWTP Standby Operator was contacted on March 14, 2024 at 3:56 a.m. to assist by placing influent pump station pumps back online. He arrived at 4:15 a.m. and turned on the pumps. At 4:30 a.m. he was notified of the sewer spill that had taken place earlier (1:15 a.m.). W.M. Lyles was contacted by the emergency phone system of the HERC Rental Company By-Pass Pumps. Upon arrival the Superintendent noticed that the two pumps near the influent pump station within the Plant were not operating. He canvassed the area and noticed that a spill had taken place along the Cricket Hollow Park parking lot. He quickly turned off the pumps along the Olson main sewer line to stop any additional sewer spill, he relieved the by-pass plug sending flow back into the influent pump station. There were multiple appearance points (see attachment).	36.58161	-119.46183	Gravity Mainline, Manhole		In addition to the manhole where the by-pass is located, five additional manholes showed sewer spill appearances ( MH #1154, MH #1153; MH #906; MH #905 & MH #899). Three manholes discharged into the Kings River at different sites (MH #1153; MH #906 & MH #905). Most of the discharged sewer was contained on dirt, concrete and asphalt areas. (Attached pictures)	1575	Several pictures are attached showing the point of appearances and additional pictures shall be submitted with the following written reports.

In addition sites where the spill was contained in dirt areas are included.	183	1392	Other (specify below), Paved Surface, Surface Water, Unpaved Surface	Construction trench	The City of Reedley Wastewater Treatment Plant is undergoing a upsizing of the Main Sewer line going into the Plant. Two By-Pass stations are in operation to divert flow from original line to perform project. One of the By-Pass stations self-priming pump failed and did not allow pump to operate. The stand-by secondary pump vacuum valve was inadvertently left shut, which did not allow it to run when the primary pump failed. As a result, the by-pass objective failed and the manhole being by-passed began to back-up and went into a lower elevated sewer line to a neighboring sewer system. The sewer line runs along a boat launch parking lot where there are several manholes sealed and bolted. The pressure from the back-up caused the sewer to seep out between the manhole rings and the manholes under the asphalt and eventually across the parking lot and into the Kings River. There were a total of four (4) manholes in this run and two in the Plant that overflowed.  See Attachment  for detailes. 	Y	36.58165	-119.46169							14-MAR-24	Previous flow calculations from similar spill events were used to calculate the volume based on Volume Estimation: Duration and Flow Comparison Method; Measurements of Stained Asphalt, Cement and Dirt Areas Affected were taken; as well as, depths in dirt areas were used to determine and calculate estimated spill flows.  See Attachment. 	Relied on the responding party's account of events and timeline to estimate when the start and end of the spill event took place. The By-Pass Alarm System called out the Contractor. The time that he responded to site , investigated the problem, discovered the sewer back-up and response action is what was taken into account. Used the City Spill/Backup Response Workbook to further calculate the discharge flows.  See Attachment. 	Air Relief Valve (ARV)/ Blow-Off Valve (BOV) Failure, Construction Diversion Failure, Operator Error (specify below), Other (specify below)	The Construction Diversion By-Pass system failed. The primary by-pass pump self-priming pump failed. The secondary by-pass pump vacuum relief valve was inadvertently left shut, which did not allow the pump to start.   See Attachment. 	Air Relief Valve (ARV)/ Blow-Off Valve (BOV), Manhole, Other (specify below)	Construction Diversion By-Pass System (primary and secondary pumps)	Other (specify below), Polyvinyl Chloride (PVC)	The main appearance point was the manhole overflowing that was being by passed, which is new and under construction. The surrounding and affected sewer system pipe, which caused the spill to go into the Kings River is PVC and Clay Pipe.	52	The Kings River received an approximate volume of 183 gallons. At the time of the spill and approximate flow of the Kings River registered at 1,250 cfs; therefore, it is believed that the Kings Rivers was minimally impacted. The Park was closed due to construction and public access denied; therefore, no public health hazard is believed to have been caused. The spill was mostly contained on asphalt, cement or dirt areas. These areas believed to be minimally impacted, as well. No debris or fecal matter visible.	N	Contained All or Portion of Spill, Other (specify below), Other Enforcement Agency Notified, Restored Flow, Returned Portion of Spill to Sanitary Sewer System	Plug valve was immediately relieved and flow restored back to the Plant upon noticing the spill at the manhole taking place. Additional pumps installed to prevent future sewer spill in the event that by-pass pumps fail; monitored system 24/7 for three days. Tested and verified equipment and monitoring systems.  See Attachment 	No clean-up efforts could be performed to disinfect the affected areas due to the proximity of the Kings River. By the time staff noted the spill had affected the parking lot areas, water had already discharged into the Kings River and across the parking lot areas. The sewer plug at the Plant was immediately removed to relieve the spill and restore flow.  See Attachment. 	Other (specify below), Repaired Facilities or Replaced Defect	Third pump was installed at the by-pass station as an added source of spill control. Monitoring devises were tested and verified. A 24/7 oversight of the by-pass system was implemented for a three day period to make sure that the by-pass systems were in good operating condition.	The City is looking at the feasibility of adding slurry around existing manholes in the area to mitigate the seepage of sewer discharge when the line is surcharged. Likewise, the installation of a containment basin where the discharge flow typically discharges into the Kings River along with a berm area to divert the flow to the basin is being contemplated. Scheduling and funding is being looked into at this time, no specific timeline has been established.

Y	37.98647	-120.38004	37.98453	-120.38079					07-APR-24	Spill volumes were calculated using the Orange County Spill Estimation Guide's  Pick and Vent Hole Estimation Chart . We measured two 3/4  pick holes both with 4  plumes of sewer coming out. The estimation chart shows this to be an estimated 8.16 GPM. We believe the spill to have ran for 102 minutes based on talks with the customers and residents in the area. This would lead to our 832.32 gallon spill.	Spill start time was estimated by talking to customers in the area. One man said he was loading up his car about 20' away from the spill point around 0835 and everything was fine. I decided to put down 0838 as this is the last time the manhole had been seen not spilling. Also, this spill is in a busy part of town and in a very visible spot. I believe this spill would have been noticed and reported very quickly. We know the spill ended at exactly 1020 because we unplugged the line and watched the spill end.	Debris-General	N/A	Manhole	N/A	Cast Iron	N/A	40	The spill did not appear to impact any wildlife or vegetation. There was no visual evidence of sewer or any contamination in or around the creek although we know it did reach the creek.	N	Cleaned Up (specify below), Contained All or Portion of Spill, Restored Flow, Returned Portion of Spill to Sanitary Sewer System	N/A	Upon arrival, crews immediately started working to contain the spill with a vacuum truck. The vacuum truck had a mechanical failure (improperly sealed tank) and wasn't able to do the job, so crews moved on to unplug the blocked line as quickly as possible with the hydro jetter truck. Once the spill had been stopped, the vacuum truck tank was resealed, and all possible sewer was collected from drains. Crews disinfected the entire spill area and cleaned it with brooms and water from the hydro jetter. All storm drains were flushed and cleaned with water and disinfectant. All water used for cleanup was collected with the vacuum truck.	Adjusted Schedule/Method of Preventive Maintenance, Inspected Sewer Using CCTV to Determine Cause	N/A	I believe this was a fluke occurrence because the condition of both the manhole and the line seem to be in good shape but we will be opening and visually inspecting this manhole quarterly from now on to prevent any future SSO's..	This manhole will be inspected again in July, then October, then January, and so on. 	07-APR-24	The line has been TV'd. We found no pipe or manhole defects that could have caused the spill, leading me to believe debris came down from upstream and got stuck in the channel of the manhole.

The area received 2.27 inches of rain in less than 48 hours on 3/23/24 through 3/24/24.

The project is utilizing heavy equipment to remove trees, dirt and meet compaction requirements.  During this work the 1in ARV service line was compromised which allowed for an intermittent .5 gpm leak. The spill was mitigated by using the surrounding dirt as containment as well as draining the force main back to the lift station. The flow at the station was then removed with our vac truck and properly returned to the sanitary sewer system at an appropriate location.

It has now been added to annual root removal work orders. The jet cleaning work order was late and will not be adjusted ass the spill would not have occurred if it was cleaned on time.		10-FEB-24	We used our CCTV equipment to inspect the main segment that plugged, and we found that it had roots in several joints. These joints also had grease to build up in those areas.  We researched the main segment in our CMMS system and found this main was on a cleaning work order that was late. The research also showed that after previous inspections a rod work order would be created and completed, but never cycled annually. We have now created a cycled rod work order that will be due annually and we did not adjust the cleaning schedule due to it being cleaned late. After the investigation we had the main rodded, and completed the cleaning work order for this main and the surrounding assets.		N/A	12-FEB-24														N/A	We added the mains in the area to an annual work order that is cycled automatically for root removal.	We did not adjust the cleaning schedule as we were significantly late on the work order. We did add it to annual Rodding that will eliminate the root problem.	N/A	N/A	N/A	N/A	N/A	N/A

It was first noticed on 2/24/2024 at 9:40 am, with the estimated start time being 2/24/2024 at 09:40. The clean-up crew arrived at the scene by 10:23. They acted swiftly to contain the spill, preventing it from further spreading. The total volume of the spill exiting the system was estimated to be around 165 units.	Y	The spill left the system and traveled two blocks down the street into the conveyance system. Approximately 10 gallons reached the storm drain's catch basin. Ocean Blue Contractors fully recovered and cleaned up the spill.	10				165	Drainage Conveyance System, Street/Curb and Gutter (2 3)		The spill originated from a manhole in the city sewer system, specifically from location N12-SMH-032, with GPS coordinates 33.78063 (latitude) and -118.14800 (longitude). The wastewater flowed along the street's curb and gutter, ultimately entering the Los Angeles County Flood Control District storm drain catch basin, representing the full spread and reach of the spill. Efforts were made to contain the spill using sandbags to prevent further contamination. Please see the attached map.	Y	33.7807	-118.14607							24-FEB-24	The spill volume was estimated based on the rate of overflow from the manhole and the time duration of the spill. Upon arrival, it was observed that the manhole was overflowing at a rate of 3 gallons per minute. The spill start time was estimated to be at 9:40 AM, and the spill was stopped by 10:35 AM, resulting in a total spill duration of 55 minutes. By multiplying the rate of overflow (3 gallons per minute) by the duration of the spill (55 minutes), the total spill volume was calculated to be 165 gallons. This calculation is based on direct observation and time tracking rather than relying on SCADA records or flow monitoring data.	The spill start time was estimated based on a statement from a local resident who noticed water coming out from the manhole at approximately 9:40 AM. The spill end time was determined by the time the cleaning crew arrived and managed to stop the overflow, which was recorded at 10:35 AM. These estimations rely on eyewitness statements and the cleaning crew's operational records.

N	Cleaned Up (specify below), Contained All or Portion of Spill, Other Enforcement Agency Notified, Restored Flow, Returned All Spill to Sanitary Sewer System		1. Spill Containment: A sewage overflow from the city sewer manhole resulted in a spill of approximately 165 gallons. Containment measures, such as deploying barriers, were implemented to prevent the spill from spreading beyond the affected area. 2. Cleanup Efforts: Ocean Blue Environmental initiated the cleanup operations for the spill on the street and in the conveyance system. A pressure washer and a vacuum truck were used to clean up the 165 gallons of sewage. 	Plan Rehabilitation or Replacement of Sewer		The corrective actions taken for the spill include immediate containment and clean-up, thorough investigation, and repair of the damage causing the spill. The containment measures were implemented promptly to prevent the spill from spreading beyond the affected area. Ocean Blue Environmental carried out cleanup operations, using a pressure washer and a vacuum truck to remove the 165 gallons of sewage from the street and conveyance system.  A CCTV inspection was conducted to identify the cause of the spill, which was found to be a damaged sewer service lateral leading to debris flowing into the main line. The damaged sewer service lateral was repaired on 3/11/2024, eliminating the cause of the spill.		24-FEB-24	A post CCTV inspection was carried out on 2/28/2024 to investigate the cause of the main line stoppage. The inspection revealed that the stoppage was due to debris entering the system from a damaged sewer service lateral. In order to rectify the problem, the damaged sewer service lateral was repaired. Additionally, the pipe segment was thoroughly hydro-jetted to ensure the normal flow of wastewater, effectively resolving the issue.

We also have a 2-year Preventive Sewer Maintenance Program in place to ensure the long-term health and functionality of our sewer system.	The repairs on the sewer lateral are now complete. We will continue with the preventive maintenance program for this section of the pipe.	The damaged sewer service lateral that caused the spill has been repaired as of 3/11/2024. Moving forward, we have a comprehensive Preventive Sewer Maintenance Program in place. This program includes regular inspections and necessary repair or replacement of the sewer assets to prevent any future spills. Our focus is ensuring the long-term health and functionality of our sewer system. This approach minimizes the risk of future service disruption and environmental impact.	CCTV inspections were carried out to determine the cause and location of the debris blockage. A faulty sewer service lateral was identified and subsequently repaired. Necessary steps were taken to ensure the blockage was thoroughly cleaned.	None Planned on this segment of mainline.

Cross street Gazelle Ct.	33.14317	-117.2551	Manhole			341	The spill originated from a manhole in the center of a two-lane street. It flowed down the street for approximately 138� and reached the curbline on both sides. On the north side of the street a small amount of the spill flowed into a storm drain inlet. However the majority of the spill stayed on the street. Because of ongoing construction at the time, the inlet was covered by a plastic screen, which helped to minimize the amount that entered the catch basin.	Y	A small volume of the spill went into a catch basin via a curb inlet and was contained there. The spill volume was very low and the curb inlet was far enough away that only a small fraction of the spill reached the  inlet. Also, BMPs were in place in front of the curb inlet because of construction in the area so very little of the spill entered the catch basin.	17				341	Drainage Conveyance System, Paved Surface, Street/Curb and Gutter (2 3)		The spill exited the manhole and spread out across the street to the curbline on both sides. It flowed approximately 130� on the south side of the street and approximately 138� on the north side, with a small portion entering a catch basin through a curb inlet. 	N									14-FEB-24	The spill volume was calculated using the area/volume method. Staff drew out the shapes of the spill area and used area and volume formulas to determine how much sewage had spilled. The amount of wastewater that reached the catch basin was estimated based on the amount that was vacuumed up. Staff checked the catch basin downstream from the one that received the flow and it was dry, so staff assumed that all of the flow that reached the catch basin stayed there. The estimated amount of the spill was then verified using the duration and flow rate comparison method.	-The start time was estimated based on an interview with the foreman for the construction company that is building on the vacant lot adjacent to the manhole location. His crew saw the spill at 6:45am. -The end time was based on the actual time that the crew got a vacuum truck set up at the manhole and stopped it from spilling. 	Debris from Construction		Other (specify below)	Dirt and silt entered an unused lateral on a construction site.	Polyvinyl Chloride (PVC)		18	There was little impact from the spill. Traffic was routed around the spilling manhole while the wastewater crew was clearing the blockage but other than that there was no impact to the public or the environment. 	N	Cleaned Up (specify below), Restored Flow, Returned All Spill to Sanitary Sewer System		A wastewater crew headed to the spill location with the combination truck as soon as they were notified. There were already BMPs set up at all curb inlets along that portion of the street. The closest curb inlet was approximately 130� from the manhole and very little flow had made it that far so the crew immediately began clearing the blockage. They set up at the downstream manhole and ran the main line three times and confirmed that the manhole was no longer overflowing. They then ran the line downstream from the manhole upstream from the spill as a precaution. A second crew arrived a few minutes after the spill was stopped to help with the cleanup effort. One crew vacuumed up the small amount that had flowed into the catch basin and the other crew proceeded to wash down the street. All of the washdown fluid was recaptured.	Other (specify below)	The unused lateral on the construction site was abandoned.	The spill was caused by dirt and silt that entered the collection system from a construction site that had a sewer lateral that was due to be abandoned. The construction company changed their schedule and abandoned the sewer lateral immediately after the spill. 		14-FEB-24	Wastewater staff televised the sewer main that had been blocked and found a sewer lateral with silt/dirt at the entrance. After looking at the city�s GIS system it was determined that the lateral belonged to a vacant lot close to the manhole, where a private construction job was occurring. Wastewater management notified the city�s Construction Management division. The inspector for that construction site verified from the plans that the lateral was due to be abandoned but that the work hadn�t been done yet. The general agreement was that the debris had somehow  entered the lateral and caused the blockage. The lateral was then abandoned.		Follow up conversations were held with the city's Construction Manager and Construction Inspector to get more information because of the construction site being the likely cause of the debris that caused the blockage. These conversations were held on 2/15 and 2/20. Follow up questions were then asked of the construction company foreman on 2/20. The investigation was then concluded because the city received all of the information needed to determine cause and start time.	20-FEB-24														n/a	n/a	n/a	n/a	n/a	n/a	n/a	n/a	Follow up conversations were held with the city's Construction Manager and Construction Inspector to get more information because of the construction site being the likely cause of the debris that caused the blockage.
