The park was not busy at the time, the majority of the park being closed. the hole was relatively small, between 1/4 & 3/8 inch. The pump station does pump a substantial amount of effluent, the majority of the effluent likely pumped on past the hole in the pipe. 900 gallons is an overestimate.

Report: Sanitary sewer overflow in the parking lot at the Mary¿s Pizza Shack at 101 Golf Course Drive. The other surrounding food service establishments were all investigated and ruled out as potential contributors or sources of the grease that caused the overflow. In the afternoon after some camera work in the private sewer laterals it was concluded that Mary¿s was the sole source and cause of the Sanitary Sewer Overflow and we met with the Maintenance Manager and General Manager for Mary¿s Pizza Shack. In this meeting they acknowledged that the overflow originated from there grease interceptor and was due to an issue with there pumping service not properly cleaning the grease interceptor. In June of 2006 the 2,000 gallon grease interceptor was installed to replace a big dipper unit. At this time Mary¿s Pizza Shack entered into a service agreement with United Site Services to service both the grease interceptor and tallow bin at this location. The problem and cause of the overflow was due to the fact that United Site Services had never pumped the grease interceptor since it was installed over 18 months ago. This location of Mary¿s Pizza Shack had been paying United Site Services for quarterly pumping service; they had the original service contract, all of the bills but no individual pumping receipts. The Maintenance Manager and General Manager were reminded of there obligations within the food service establishment permit, and that it was there sole responsibility to ensure that the grease interceptor was properly cleaned and maintained. This same issue has not occurred at any of the other Mary¿s Pizza Shack locations and the Maintenance Manager assured me that this issue has been rectified and will never occur again at the Rohnert Park location. A new service contract which includes quarterly pumping services was provided at the end of the meeting. A corrective action notice was issued to have the grease interceptor pumped and the sewer lateral cleaned and a Notice of Violation will follow. Corrective Actions to be taken by Mary¿s Pizza Shack ¿ The sewer lateral from the grease interceptor to manhole #545 and out to manhole #544 will be jetted and cleaned. ¿ The grease interceptor cleaned. ¿ This location will have a new service contract which includes quarterly pumping of the grease interceptor and Mary¿s staff will ensure that all future contractor grease interceptor maintenance and cleaning work is actually being done. 6 PVC Cleaned-up (mitigated effects of spill);Contained all or portion of spill;Inspected sewer using CCTV to determine cause;Restored flow;Returned all or portion of spill to sanitary sewer system N/A 080490 01/16/2008 03:17 1 1SSO10016 Active 725567 Michael Bracewell Certified Services Supervisor - Utilities 09/02/08 2:45 p.m. 602959 02-SEP-08 02-SEP-08 09/02/2008 Category 3 18 18 0 No Yes Yes 1400 East Cotati ave. 38.332972 122.689706 Sonoma 1 Manhole in paved street.

The City contacted the HOA to bring this to their attention on Feb 22, 2012 and the HOA had a hired contractor on site Feb 23, 2012 to clean all their private sewer collection lines with a Vactor truck and had another Vactor truck standing by vacuuming up large grease deposits just as they entered the City¿s sewer collection system. The HOA has had problems in the past with blockages at this HOA they were cleaning quarterly for several years and may have stopped due to a change of board members. They were informed to hire a contractor to monitor and clean their collection system pipes on a regular basis. This HOA site is has been placed on the City¿s quarterly monitoring schedule to assure this does not happen again.

A Emergency Operations Center was established, and all the emergency agencies mobilized to deal with all of the percipitation. The County has 18 lift stations and all of those lift stations were under extreme pressure. All of the equipment that could pump and transport wastewater was mobilized to deal with lift stations that would overflow without support. This lift station was the one station that we could not handle since we had all of our manpower and equipment on other stations. Other (specify below) The lift station could not keep up with the flows and therefore the level in the wet well got high enough that the water began discharging out of the lowest spot on the basin. 4 pvc Other (specify below) As soon as we were able to mobilize a truck to this lift station the problem was solved. 03/31/2012 11:30 Other (specify below) The pumps in the pump station will be analyzed to determine that they were pumping at top efficiency. We are also replacing these pumps with new submerable pumps in the next few years. Also new SCADA equipment is being implimented into all of the County Lift Stations. One of the most troublesome lift stations in the system is being rebuilt this next summer, which will allow personel and equipment to concentrate on other areas. Yes No visual change.

This blockage caused the sewage to dicharged from a private cleanout cap located on the property of 255 Dry Creek Road. The sewage traveled across a large semi paved/ base rock parking lot and entered the stormdrain. Once the sewage was in the storm drain it discharged into nearby Foss Creek. Gravity sewer Sewage discharge from a private property cleanout and then entered a strom drain box then traveled to and discharged into Foss Creek at a mesured amount of 24.5 gpm. Surface water The sewage had traveled across a large fairly flat parking lot. The paking lot was made of partial pavment and partial exposed gravel. The sewage entered into a storm drain inlet box which discharged into Foss Creek. Further interviews with witnesses of this sewer event will be conducted when they are availble to meet with City of Healdsburg staff members to help add additional facts to this report. 05/28/2013 09:13 05/28/2013 10:02 05/28/2013 10:13 05/28/2013 10:35 Debri-Rags During the jetting clearing process the blockage was identified as a large fiberous ragball including a stick that was observed passing through the downstream manhole Main Fiberous rag had been discharged somewhere up stream of the blockage from a residents or businesses . The rag ball and stick may have jammed inside the pipe allowing more material to collect until the sewer pipe filled and overflowed. 6 Cleaned-up (mitigated effects of spill) First City of Healdsburg Public Works employees on scene made the phone call for assistance and requested additional employees to respond immediately to the scene. Staff members used a jetter Vacuum truck to clear the blockage. The next incoming units were assigned to documentation of the event. Other employees arriving at the same time were requested to deploy straw waddles, apply BPM's and dirvert sewage away from the storm drain inlet in the parking lot to prevent any further sewage from entering the storm drain. The City of Healdsburg Lab tech was requested to collect and document up stream samples, spill location samples, and downstream samples. Samples included Dissolved Oxygen, pH, Temp, BOD, TSS and Coliform samples were collect from each of the three locations. Clean up included parking lot clean up and wash down. All captured sewage and cleaning water was transported or returned to the City of Healdsburg sewage collection system. An additional phone call was placed to Kyle our local CA. Fish and Game Warden to inform him of the spill. At the Wardens request a secondary inspection of the affected area would be conducted on 5/28/2013. After futher investigation and witness interview with the neighbor. The start time of the sewage spill was changed to 9:45am from the origional time recorded as 9:13am. With this time chage the new calculated discharge amount into Foss Creek was 1,225 gallons. Brian Diamantini City of Healdsburg Wastewater Utility Foreman logged into this document on 6/24/2013 to make the changes to this document. 05/28/2013 16:30 Other (specify below) This blockage was caused by users of the sewer collection system. A letter will be sent to the upstream residents informing the occupants about the affects by discharging fiberous rags into the City of Healdsburg sewer collection system. The spill has been recalculated to be 1, 225 gallons of sewage that could not be recovered from Foss Creek Yes Initail inspection during the spill indiated a very light turbidity(cloudyness) to Foss Creek.

The appearance point was first noticed on October 30, 2018 but was hidden and misidentified as an unauthorized haz-mat spill into the storm culvert. Later determined not to be hazardous, the spill was reported as unknown source. Sewer line maintenance in June 2019 revealed the exact source of the this spill appearance point, determined to be small cracks in cast iron piping intersecting the drain culvert. The gravity sewer flow from the leak was measured to flow approximately 0.109 gallons per minute. Drainage Channel;Surface Water 10/30/2018 13:48 06/24/2019 11:03 06/24/2019 11:03 06/24/2019 11:48 Pipe Structural Problem/Failure It was determined that the cause was age deterioration of the cast iron piping. The piping section was repaired with a permanent PVC slip-line approximately 2 weeks after the temporary repair/spill occurred. Gravity Mainline No 8 Cast iron Mitigated Effects of Spill;Restored flow Spill response included immediate spill stoppage and temporary repair. As this spill was very low flow (0.109 gpm) and long duration, the vicinity had no apparent impact and had been flowing unnoticed for approximately 9 months. Downstream areas near the spill are not used for recreation and no nuisance was reported. Spill capture was not possible or advised as the stream was active with fish. 06/24/2019 14:08 Inspected Sewer Using CCTV to Determine Cause;Plan rehabilitation or replacement of sewer;Repaired Facilities or Replaced Defect No Water in the immediate vicinity had no visual impairment and downstream areas were in a condition reflective of the seasonal nature of a slow flowing creek. No No NA Russian River Biological indicator(s) - specify below;Not applicable to this spill Ammonia, Total and Fecal Coliform samples taken to verify effectiveness of temporary pipeline fix, but not required for this spill. Duration of spill prevented representative sampling. Other (specify below);Not applicable to this spill Samples taken reflected results typical of long slow spill in very low flow drainage ditch, but not necessarily representative of determined spill volume. Two sets of samples taken revealed restoration to typical background biological results within days of end of spill. Ammonia samples results were also indicative of background levels. Flow captured in bucket for a period of time, then quantity measured to give GPM. Total spill time and volume estimated using first known occurrence date of spill at this location. Estimated spill start date identified when unknown substance was found in same drainage channel, mistakenly determined to be an unrelated spill or dumping at the approximate location. Actual cause of spill was not readily determined until routine CCTV inspection revealed the failure. 194062 06/24/2019 13:30 Rob Scates, Water/Wastewater Operations Superintendent 7074313369 1 1SSO10037 Active 859773 Rob Scates Certified Water/Wastewater Superintendent 0903 928330 15-JUL-19 07/15/2019 16-JUL-19 07/16/2019 Category 3 576 576 0 0 No No Not Applicable - Spill did not reach a separate storm drainpipe 700 Benjamin Way 38.61951 -122.85172 Sonoma 1 Spill from manhole in sloped vegetation area near the reported address. 1 Manhole Drainage Channel;Other (specify below) Spill absorbed by dirt and terrain within 100 feet of appearance point.

The property owner stated he saw it bubble over the clean out for less than five seconds. The root ball eventually filtered through the sewage, ending the overflow. We didn't come out to the scene this day due to the shortness of the spill and the fact that we had an excavation scheduled for the next day. There was no more overflows at this location.

The underlying cause, however, was a separation of the sewer pipe at a connecting point between two lengths of pipe where the bottom of the pipe separated approximately 1-2 inches. This created a small differential in height between the underbed of the pipe and the pipe lip. Toilet tissue and debris got hung up on the lip and additional toilet tissue and debris started to get caught up on the prior tissue until it accumulated to the point that it obstructed flow in the pipe. Where the offset occurred, an additional lateral was tied into the main. After exposing the pipe in order to repair the offset, the contractor performing the repair stated that it appeared that when the wye for the additional lateral was installed, that there was insufficient compaction under the lateral. This allowed the lateral to settle which applied pressure the main eventually stretching and deforming to rubber couplers. This pressure and deformation are what finally caused the offset in the main. Gravity Mainline The failure occurred in the sewer gravity main at each of two rubber couplers that were applied to accomodate a wye used to tie a lateral from another hook up to the collection system.The new lateral was not installed straight on and was also at an angle due to the lateral having to cross a storm drain. The angle and the slightly off put angle of the lateral is what created the pressure that eventually caused the sewer main to offset/seperate. No 6 PVC 20 Cleaned-Up;Mitigated Effects of Spill;Other (specify below);Restored flow Initially, tried to clear assumed blockage from the clean out. This was able to greatly reduce the spill flow. Flushing the lateral from the clean out appeared to stop the spill flow altogether. The following morning, however. The spill re-appeared in the same location again. Attempts to clear any blockage, with a snake that the district had on hand, showed that a longer snake would be necessary to properly clear the obstruction. An outside contractor, with a longer snake, was brought in and was able to clear the blockage thereby completely stopping the spill-flow. A camera inspection crew was brought in to inspect the lateral and sewer main. The inspection revealed the pipe separation. An emergency response, clean up crew was brought in to clean the house and yard where the spill occurred. This even included removal of soil from the yard that had come in contact with sewage overflow spill. Additionally, a contractor was brought in to perform emergency repairs to the offset sewer main. 04/11/2018 17:00 Adjusted schedule/method of preventive maintenance;Inspected Sewer Using CCTV to Determine Cause;Repaired Facilities or Replaced Defect Initially, attempts were made using a manual snake that the district had on-hand to clear (locate and clear) suspected blockage in either the lateral or the sewer main. At first, this seemed to correct the issue. As stated previously, however, the spill presented itself again. Therefore, a team with a longer (and powered) snake was brought in. They snaked the lateral and part of the main and were able to clear a felt blockage. This brought an end to the spill for good. Following that, a camera inspection of the lateral and the main sewer pipe was performed. Given the information gathered from the inspection viz., offset pipe/pipe separation, a contractor was brought in to make emergency repairs to the pipe. Additionally, a cleanup response crew came in to clean up the house and yard (including soil removal from the spill location). Yes Duration and flow rate method was utilized to estimate the spill volume. Given the pipe diameter (4 ), the horizontal distance from the pipe opening to the outer edge of the water flow (2 ), and the vertical distance from the top of the pipe to the ground(5 ), an estimated flow rate was calculated. This flow rate was multiplied by the estimated time/duration of the spill to arrive at the estimated volume of the spill given at the beginning of this report.

The location essentially was just off the center of the road and approximately 7.5-8 feet below grade (the spill occurred in a trench that was dug out from a private residence to the gravity sewer main buried in the road). 1 Gravity Mainline The spill appearance point was from a broken gravity sewer main line. Other (specify below);Unpaved surface The final spill destination, indeed, was unpaved. It was not, however, what I would normally call an unpaved surface as the spill was never to or above grade with the road (surface of the road). The spill from the gravity main line spilled into a trench that had been dug just prior to the main line being broken. So the spill destination was unpaved though I am not sure it would constitute a surface except that the final destination was an unpaved medium which I suspect is not typically the connotation when one chooses the noun, surface . 05/16/2018 17:00 05/16/2018 17:30 05/16/2018 17:30 05/17/2018 11:00 Damage by Others Not Related to CS Construction/Maintenance (Specify Below) A property owner on Maple Drive rented a mini-excavator. In the course of using the mini-excavator, he hit and broke the sewer gravity main buried in the road. Gravity Mainline The failure was not a true failure, at least not in the common connotation of the word failure . The system performed as it should until such time as a property owner exposed and damaged a sewer main. The leak, or unintended discharge, of sewage occurred with, or at, the gravity sewer main in a trench. The trench in question, and the damage to the pipe, was dug, and caused, by this property owner while running a mini-excavator that he rented.

On Saturday morning, when it became obvious that the inflow to the wet well was sufficient such that the wet well would have to be pumped down before Monday morning to avoid an overflow, since septic pump trucks are not available for hire on the week ends, the operator purchased a trash pump, 275-gallon tank, and necessary hoses etc to pump down the wet well into the tank in his pick-up truck and transport it to the waste water plant where the pumped waste water could be discharged into the headworks of the facility. He pumped as long and quickly as he could, for as close to around the clock as he could to prevent further overflow and to get ahead of the overflow to create a buffer in the wet well to prevent overflow as much as possible. A cover made of pond liner and bermed with sand bags was installed at the storm drain to minimize any overflow entering and making its way to surface water. Overflow to land was sucked up with the pump as much has possible and discharged to the waste water plant head works. Lastly, a new motor starter was ordered (one had to be built for us) on Friday and rushed delivery requested. Even so, Monday morning was the earliest it could be delivered. Once it was received, the operator installed it and began pumping down the wet well using a lift pump-effectively ending the spill event.

United State Coast Guard checked river under dock at completion of activities. No NA Noyo River. In response to signage County health directed us to only post if people where present in the area. It was raining lightly all day and no one was in the area. Fish and Game directed us to look for any divers in the adjacent bay and tell them to get out of the water if we encountered any. I requested the Coast Guard while on routine patrol / training to look for divers in bay and to notify City if any where seen. USCG went under way after the spill. No divers where seen. Biological indicator(s) - specify below Fecal and E. Coli where the tests specified by the County Health Department County Health Agency;Regional Water Quality Control Board Results of Fecal will not be ready until Saturday. We also did turbidity test of all samples as a comparison. Coli form tests where also done. Update 6-01-2009, all test results where comparable to flows and conditions of the river during regular water source testing at a location up river. The river tests positive for E-coli and fecal year round. When comparing the results, they show a rise in both E-coli and Fecal during the rain event as well. After the river cleared from the rain storm and we retested our results showed a lower levels of each. After the storm, one test area well upstream 1000' showed higher levels of fecal and E- coli than during the spill. 093480 05/06/2009 09:25 1 1SSO11467 Active 749333 Linda Ruffing Certified City Manager 11:19 767216 11-FEB-10 11-FEB-10 02/04/2011 Category 1 54 30 11 Yes Yes No Chief Celeri Drive 39.443593 -123.80664 Mendocino 1 Spill was forced to the alley surface through a seam in a utility ditch from pressure of the blockage down stream.
