1124610 01/22/2024 CAT1 UV Dose Daily Minimum limit is 100 mJ/cm2 and reported value was 83.1 mJ/cm2 at INT-002. *** MMP Exempt Reason:No discharge to surface waters. The downstream reclamation system diversion mode was activated in order to divert flow to Brown Pond in response to the event. The actual dose during this diversion was maintained above 100 mJ/cm2 if the treatment supplied by redundant banks was allowed to be included. On January 22, 2024 at 01:14 the calculated UV dose surpassed the 100 mJ/cm2 minimum dose threshold. Plant effluent then began meeting all permit limits and the diversion was stopped. The average plant flow during the diversion was 38.5 mgd. The duration of the diversion was 88 minutes. The amount of affected flow was approximately 2.35 million gallons. There were no recycled water deliveries to irrigation customers during the event and Calpine was immediately notified of the offspec water by Reclamation Staff. Violation B eSMR
1124611 01/21/2024 CAT1 UV Dose Daily Minimum limit is 100 mJ/cm2 and reported value was 84.1 mJ/cm2 at INT-002. *** MMP Exempt Reason:No discharge to surface waters. For the first event - at 20:58 a UV Channel 1 low dose alarm activated, and the LTP SCADA system immediately diverted the effluent flow to an offline pond. The electrician corrected the electrical problem with the UV system. The plant remained in diversion mode until January 21, 2024, at 23:25 hours. The duration of the diversion was 177 minutes. The average plant flow during the diversion was 47.66 million gallons per day (mgd), and the total effluent flow affected was 5.86 million gallons. The lowest calculated UV dose during the diversion was 99 mJ/cm2. There were no recycled water deliveries to irrigation customers during the event and Calpine was immediately notified of the off-spec water by Reclamation Staff. For the second event - the downstream reclamation system diversion mode was activated in order to divert flow to Brown Pond in response to the event. The actual dose during this diversion was maintained above 100 mJ/cm2 if the treatment supplied by redundant banks was allowed to be included.

1124609 01/15/2024 DMON The UV channel 3 Total Coliform sample for January 15, 2024 was invalidated due to an analytical error in the laboratory. Staff was counseled and the issue has been resolved. Violation B eSMR
1124608 01/13/2024 CAT1 UV Transmittance Daily Minimum limit is 50 % and reported value was 49.4 % at INT-002. *** MMP Exempt Reason:No discharge to surface waters. The cause of the low UVT was excessive landfill leachate loading in the plant influent. Analysis of leachate input to LTP indicated that leachate deliveries from the landfill exceeded the expected number of trucks per hour. The landfill was trying to empty their leachate holding ponds in advance of the coming storms and brought too much at one time driving down the UVT. Santa Rosa Water Environmental Compliance staff are currently working with the Central Landfill staff to limit the rate of leachate delivery so that even if their leachate ponds are in alarm and at risk of overtopping, the treatment plant cannot take more than the agreed upon amount rate. Violation B eSMR
1122925 11/11/2023 CAT1 UV Dose Instantaneous Minimum limit is 100 mJ/cm2 and reported value was 96.9 mJ/cm2 at INT-002. *** MMP Exempt Reason:No discharge to surface water. The cause of the event is unknown. In the past, leachate from the Mecham Road Central Landfill has been identified as a source of wastewater exhibiting low UVT. Santa Rosa Water staff inquired with Central Landfill staff after the event and determined that the leachate pipeline normally used to convey leachate to LTP was offline for repair. Review of the trucked waste logs for the period leading up to the event and during the period of low UVT showed that the amount of leachate delivered through the trucked waste program was not excessive compared to similar weeks before and after the UVT event. Santa Rosa Water Environmental Compliance staff checked with Industrial Users and could not identify any abnormal conditions around the time of the event. There were no recycled water deliveries to irrigation customers during the event and Calpine was immediately notified of the off-spec water by Reclamation Staff. Violation B eSMR

1117508 04/05/2023 CAT1 UV Dose Instantaneous Minimum limit is 100 mJ/cm2 and reported value was 93.8 mJ/cm2 at INT-002. A review of the UV program found a hard programmed alarm delay of 5 seconds for the Low Low Dose Delivered alarm which points to the reason why LTP operations staff were unaware of the event. The programming has been altered and the delay has been changed to 0 seconds so staff will be made aware of any Low Low Dose events regardless of the duration. Furthermore, a metric to display the lowest dose of the day will be added to the daily report so management can be made aware of potential low dose situations sooner. Violation B eSMR
1108825 08/04/2022 CAT1 UV Dose Instantaneous Minimum limit is 100 mJ/cm2 and reported value was 23 mJ/cm2 at INT-002. The City will install an additional UPS and power supply for the UV PLC so that in the event one fails, the other will continue providing power. Additionally, procedures will be put in place so that when the UV PLC is worked on, the controls to the UV channel influent gates will be turned off to prevent unanticipated operation of the system. Senior Operations staff will also receive refresher training on investigating off-spec events so that support staff are notified in a timely manner of any off-spec condition. Violation B eSMR
1107578 07/13/2022 Order Conditions UV Dose Daily Minimum limit is 100 mJ/cm2 and reported value was 0 mJ/cm2 at INT-002. The Operators involved were counselled on their error and the Standard Operating Procedure (SOP) for shutting down the UV system was updated. This procedure was reviewed by the Wastewater Treatment Superintendent and has been added to the City's SOP Library and distributed to Operations staff for training. Violation B eSMR
1107579 07/07/2022 DMON The Total Coliform sample for UV Channel 2 was invalidated due to the analyst failing to properly set-up the test when performing the analysis. As a result, staff received counseling regarding the error. Violation B eSMR
1104442 04/01/2022 DMON Total Coliform sample for UV Channel 1 was invalidated due to the analyst failing to properly set-up the test when performing the analysis. Staff was counseled regarding the error. Violation B eSMR
1098183 11/08/2021 DMON The Total Coliform sample for UV Channel 1, sampled on November 8, 2021, was invalidated due to the analyst using expired media when performing the analysis.

1097308 10/28/2021 CAT1 UV Transmittance Instantaneous Minimum limit is 50 % and reported value was 48 % at INT-002. *** MMP Exempt Reason:No discharge to surface water at this time. The root cause of the incident was due to the high amount of rainfall brought by the October 24th category 5 atmospheric river that culminated in approximately 10 inches of rain. Throughout and due to the storm event, trucked waste haulers were bringing increased amounts of leachate from landfills and composting facilities to the plant. To proactively prevent the trucked leachate from negatively impacting UVT values, the leachate was stored in the emergency holding basin (EHB) for later treatment. Plant staff accommodated waste haulers throughout the storm event but ultimately had to temporarily cease deliveries as the system continued exceeding capacity. The combined efforts of storing trucked leachate and ceasing hauling allowed the plant to return to on-spec operations following the off-spec event that occurred October 24th through 26th, 2021. Once the plant returned to stable, on-spec operations following the storm event, operators began feeding the stored leachate into the headworks and again began accommodating trucked leachate haulers. The amount of leachate needing to be returned from the EHB following the storm event in combination with the trucked deliveries ultimately caused a dramatic reduction in UVT and the subsequent off-spec event. Violation B eSMR
1097313 10/26/2021 CAT1 UV Dose Instantaneous Minimum limit is 100 mJ/cm2 and reported value was 75.1 mJ/cm2 at INT-002. *** MMP Exempt Reason:No discharge to surface water at this time. Staff responded by manually diverting primary effluent to the flow equalization basins. Mechanical Services on-call staff responded to the failure. However, by the time the primary effluent channel control valve was manually opened, much of the flow equalization basin storage had already been used. At approximately 1500 hours, the usable storage space in the flow equalization basins had been utilized and the plant began taking all influent flow. The off-spec water was either captured in City-owned recycled water storage ponds or conveyed into the Geysers recharge system pipeline. Verbal and email notification were provided to the Geysers informing their operation of the off-spec water delivery and estimated time when it would reach terminal reservoir. Violation B eSMR

Violation B eSMR
1092485 06/29/2021 DMON On June 29, 2021 at 1349 hrs. the filter effluent turbidity meter went offline. Staff became aware that the meter was offline at 2000 hrs. and immediately began hourly reads using a bench top turbidity meter. Upon further investigation of the incident, staff discovered that a light bulb failure in the meter caused the instrument to go down. The light bulb was replaced, and the turbidity meter was placed back into service at 0728 hrs. on June 30, 2021. The turbidity before and after the off-line period was 0.7 NTU and there is no indication that there was a turbidity violation during the event. The Treatment Plant Operator on shift was counseled on checking trends twice per shift, as required in the Operators¿ work plans. Violation B eSMR
1091446 05/18/2021 DMON There was only one reportable Biochemical Oxygen Demand results for treatment plant final effluent for the week of May 16-22 because of analytical quality control failure. As a result of the QC failure the City of Santa Rosa began subcontracting BOD samples to an outside laboratory allowing staff to investigate the cause of the failed QC without risking further analytical results. While the investigation is still ongoing, QC issues have been resolved and it is likely they were a result of poor-quality BOD dilution water. City staff is working with the deionized water system vendor to provide a maintenance frequency that will help eliminate future BOD QC issues. Violation B eSMR

1082170 10/15/2020 DMON The filter effluent turbidity meter was placed in the hold position for calibration purposes. Difficulties with the calibration process caused the on-line monitoring of the filter effluent to be paused for 1 hour and 47 minutes, from 1456 hours to 1643 hours. This exceeded the permitted monitoring requirement to record the filter effluent turbidity levels at intervals of no less than once every 1 hour and 12 minutes over a 24-hour period Prior to the meter being placed on hold the effluent turbidity was averaging 0.64 NTU and after the meter was placed back on-line the effluent turbidity averaged 0.72 NTU. The operator involved received counseling on this matter. Violation B eSMR
1076256 05/31/2020 DMON There is no reportable Chloride result for May 2020 due to a laboratory analyst error in missing the regulatory hold time during a period of reduced staffing levels related to Covid-19.

1075288 04/28/2020 DMON On April 28, 2020 the on-line ultraviolet transmittance (UVT) analyzer was put on hold at 0802 hrs. for the analyzer to be checked. The actual UVT value before the hold was 62 percent; following established protocol, the manual output during the check was set to 60 percent to compensate for unexpected drops in UVT during the procedure. The Treatment Plant Operator forgot to place the UVT analyzer back on-line after the check was completed and the hold continued until 1542 hrs. at which time it was placed back on-line. The actual UVT value at that time was 64 percent. For 7 hours and 40 minutes there was no monitoring of the actual UVT value. Typically, the treatment plant¿s UVT value increases during daytime hours, and decreases late night/early morning. There is no reason to believe that the UV system did not provide full dose during the affected period and the coliform results for April 28 were non-detect for all three on-line channels. To prevent this type of incident from recurring, an alarm will be programmed to alert staff if the analyzer is on hold longer than 20 minutes. The employee involved in the incident received appropriate counselling. Violation U eSMR
1073324 03/09/2020 DMON There was no reportable Total Suspended Solids result for treatment plant final effluent on March 9, 2020 due to soap residue in the sample after a Treatment Plant Operator cleaned the autosampler with soap. The Operator was counseled that day on the proper procedure for cleaning autosamplers using brushes and water without soap. The autosampler was thoroughly rinsed and put back into service the same day. Violation U eSMR
1073323 03/02/2020 CAT1 UV Dose Instantaneous Minimum limit is 100 mJ/cm2 and reported value was 86 mJ/cm2 at EFF-001. The under-disinfected water was either captured in City-owned ponds or conveyed into the Geysers recharge system pipeline. Reclamation and Geysers operations staff were immediately informed of the event and received follow-up calls from Laguna staff. Following investigation of the incident, it was determined that an electronic connection to the installed communication board had not been properly landed, and that the operational Standard Operating Procedure (SOP) for channel maintenance of this type had not been strictly followed. If the SOP had been followed in its entirety, the resulting dose would possibly have been sufficient to maintain the required dose. The communications board for the affected module was reinstalled correctly after the incident and is currently functioning properly. Employees involved in the incident will receive appropriate counselling. Violation U eSMR
1072100 02/25/2020 DMON There were no reportable Total Coliform results on February 25, 2020 from the Laguna Treatment Plant UV Disinfection Channels due to a laboratory error during sample inoculation. The error was not discovered until samples were retrieved from the incubator the following day at which time the samples were invalidated. The lab staff will receive refresher training on best practices for sample organization during inoculation as corrective action to prevent this error from reoccurring. The training for lab staff will occur once the ¿shelter in place¿ order issued by the Sonoma County Health Officer is lifted and normal operations can resume. Violation U eSMR
1082005 08/23/2019 OEV Total Coliform 7-Day Median limit is 2.2 MPN/100 mL and reported value was 2.4 MPN/100 mL at EFF-001. *** MMP Exempt Reason:Violation occurred when not discharging to surface waters.
