1066098 08/29/2019 DMON During the Q3 offshore monitoring conducted on August 29, 2019, a total of three rounds of monitoring occurred across the 16 offshore monitoring locations, weather and water conditions permitting, and twice across one offshore monitoring location E-30 (located 1,000 feet downcoast of the discharge channel and 2,000 feet offshore). The contractor conducting the monitoring inadvertently missed station E-30 in the first round of monitoring. The receiving water monitoring contractor has updated the QA/QC procedure to ensure offshore monitoring is conducted as specified in Order R9-2019-003 to the maximum extent practical, while taking into consideration conditions which could make sampling hazardous at monitoring locations. Violation U eSMR
1066097 08/29/2019 OEV pH Instantaneous Maximum limit is 8.46 SU and reported value was 10.12 SU. The pH at surf zone monitoring locations A-50 (surf zone monitoring location 328 feet up-coast of the discharge channel) A-90 (surf zone monitoring location 656 feet down-coast of the discharge channel) exceeded the maximum limit allowed per the Order during the Q3 monitoring period. The Order states that the pH in the surf zone cannot exceed 0.2 standard units above which occurs naturally at any time. The maximum pH value recorded for A-00 (surf zone reference monitoring location) was 8.26, whereas the maximum pH value recorded for station A-50 was 9.98, and station A-90 has a maximum pH value of 10.12. This pH results in question represent two samples collected out of a total of 72 pH samples collected at the surf zone and offshore monitoring stations on August 29, 2019. Given the significant buffering capacity of the Pacific Ocean, it would be extremely difficult to elevate the pH in a localized area by nearly two full pH units. Consequently, Discharger is of the opinion that the results are due to instrument error rather than something attributable to the discharge. As further support for this opinion, Discharger notes that the salinity values measured concurrently with the elevated pH values were consistent with that of the natural background, indicating the discharge plume was not the cause of the elevated pH readings. The stations were re-sampled twice later in the day and had results that were within the allowed limit and comparable to the natural background pH. The field team notes that there was no known reason for the elevated pH at these two stations. Future surf zone monitoring efforts will focus on the monitoring of this station and tracking any trends that could potentially provide an explanation for the higher pH values during this monitoring event. Violation U eSMR
1066099 07/30/2019 DMON TCDD analysis for the CY19 Q3 reporting period was not conducted in accordance with Attachment E, Table E-4. Effluent Monitoring at M-001 when not Discharging Brine of the Order. While the CDP Operator collected the CY19 Q3 monitoring samples the Chain of Custody (COC) was not updated to include the new TCDD monitoring requirement. CDP Operator has revised the Quarterly Chain of Custody (COC) template to reflect monitoring conditions identified in Attachment E, Table E-4 Effluent Monitoring at M-001 when not Discharging Brine of the Order. CDP Laboratory Director has further reviewed NPDES monitoring requirements with the external laboratory to mitigate a reoccurrence. Violation U eSMR
1059445 04/05/2019 OEV Salinity Daily Average (Mean) limit is 40 ppth and reported value was 42 ppth at M-002. Discharger believes the salinity exceedance at M-002 is due to a laboratory error. Data from the continuous salinity sensor at M-002 (CIWQS attachment "04.05.2019 NPDES Daily Salinity_CDP") shows the discharge was within compliance on the date the grab sample was collected (daily average salinity of 37.27ppth; instantaneous max of 38.48 ppth). Violation B eSMR
1059444 04/02/2019 CTOX Chronic Toxicity Daily Maximum limit is 16.5 TUc and reported value was 40 TUc at M-001. The chronic toxicity test results are an artifact of the conservative toxicity testing procedure set forth in the NPDES permit for the CDP, and did not result in harm to the environment. Under existing regulations, the CDP is required to meet the toxicity standard after initial mixing occurs. Initial mixing includes the mixing of the CDP's brine discharge with four gallons of seawater prior to discharge to the Pacific Ocean; and then the combined discharge receives additional mixing in the ocean prior to reaching the compliance point under the permit that is located 1,000 feet offshore. Under the terms of the permit, the CDP is required to test for toxicity at higher discharge concentrations than is actually occurring at the compliance point. This is because the chronic toxicity testing procedure set forth in the permit does not take into consideration the initial dilution provided prior to discharge to the ocean. In accordance with the Order accelerated toxicity monitoring was initiated. Violation B eSMR
1057321 02/08/2019 OEV Salinity Daily Average (Mean) limit is 40 ppth and reported value was 41 ppth at M-002. Discharger believes the salinity exceedance at M-002 is due to a laboratory error. Data from the continuous salinity sensor at M-002 (CIWQS attachment "02.08.2019 NPDES Daily Salinity_CDP") shows the Discharger was within compliance on the dates the grab sample was collected (daily averages of 35.70 ppt). At no point during the month of February did the continuous salinity sensors record a salinity at or above 40 ppt. Discharger has developed a communications protocol with the contract laboratory to notify Discharger of preliminary results exceeding effluent salinity measurements. The notification will alert the operations team of the need to initiate an investigation into the exceedance and conduct additional analysis as needed. Violation B eSMR
1057320 02/01/2019 OEV Salinity Daily Average (Mean) limit is 40 ppth and reported value was 43 ppth at M-002. Discharger believes the salinity exceedance at M-002 is due to a laboratory error. Data from the continuous salinity sensor at M-002 (CIWQS attachment "02.01.2019 NPDES Daily Salinity_CDP") shows the Discharger was within compliance on the dates the grab sample was collected (daily averages of 35.37 ppt). At no point during the month of February did the continuous salinity sensors record a salinity at or above 40 ppt. Discharger has developed a communications protocol with the contract laboratory to notify Discharger of preliminary results exceeding effluent salinity measurements. The notification will alert the operations team of the need to initiate an investigation into the exceedance and conduct additional analysis as needed. Violation B eSMR

1056520 01/31/2019 Order Conditions On January 31, 2019 the effluent discharge from the Carlsbad Desalination Plant (CDP) caused a discoloration of the Pacific Ocean (the receiving waters) beyond the discharge channel. Discharger provided immediate verbal notification and formal Incident Report (IR) to the SWRCB. Discharger has uploaded the IR to include CDP Operator findings and corrective actions to CIWQS as attachments for the January 2019 reporting period. Violation B eSMR

1043033 03/31/2018 CAT1 Total Suspended Solids (TSS) Monthly Average (Mean) limit is 60 mg/L and reported value was 68.43 mg/L at M-001. Discharger has developed a communication protocol with the contract laboratory to notify Discharger of preliminary results exceeding effluent TSS measurements which will alert the operations team of the need to initiate an investigation and conduct additional analysis. Discharger will continue to monitor M-001 discharges in accordance with the Order. Violation B eSMR
1041051 02/09/2018 CTOX Chronic Toxicity Daily Maximum limit is 16.5 TUc and reported value was 20 TUc at M-001. The chronic toxicity test results are an artifact of the conservative toxicity testing procedure set forth in the NPDES permit for the CDP, and did not result in harm to the environment. Under existing regulations, the CDP is required to meet the toxicity standard after initial mixing occurs. Initial mixing includes the mixing of the CDP's brine discharge with the discharge from the Encina Power Plant (four gallons of seawater exiting the power plant is mixed with every gallon of brine leaving the CDP); and then the combined CDP/power plant discharge receives additional mixing in the ocean prior to reaching the compliance point under the permit that is located 1,000 feet offshore (15 gallons of seawater mixes with every gallon of combined CDP/power plant discharge prior to reaching the compliance point). Under the terms of the permit, the CDP is required to test for toxicity at higher discharge concentrations than is actually occurring at the compliance point. This is because the conservative testing regime set forth in the permit fails to take into consideration the initial dilution provided by the power plant. In accordance with the Order, further steps are being taken to identify and minimize source(s) of toxicity. Accelerated toxicity monitoring was initiated immediately after the first test demonstrating a toxicity issue and a Toxicity Investigation Evaluation (TIE) is being conducted in conformance with a Regional Water Board approved Toxicity Reduction Evaluation (TRE) Plan. The TIE includes investigative toxicity testing to identify the source of the toxicity. The Discharger has been in close communication with the Regional Water Board on the CDP toxicity monitoring and the TIE. Additional sampling and testing will continue in an effort to identify and minimize the source(s) of toxicity. Violation B eSMR

1034094 09/04/2017 CTOX Chronic Toxicity Daily Maximum limit is 16.5 TUc and reported value was 20.0 TUc at M-001. The chronic toxicity test results are an artifact of the conservative toxicity testing procedure set forth in the NPDES permit for the CDP, and did not result in harm to the environment. Under existing regulations, the CDP is required to meet the toxicity standard after initial mixing occurs. Initial mixing includes the mixing of the CDP's brine discharge with the discharge from the Encina Power Plant (four gallons of seawater exiting the power plant is mixed with every gallon of brine leaving the CDP); and then the combined CDP/power plant discharge receives additional mixing in the ocean prior to reaching the compliance point under the permit that is located 1,000 feet offshore (15 gallons of seawater mixes with every gallon of combined CDP/power plant discharge prior to reaching the compliance point). Under the terms of the permit, the CDP is required to test for toxicity at higher discharge concentrations than is actually occurring at the compliance point. This is because the conservative testing regime set forth in the permit fails to take into consideration the initial dilution provided by the power plant. In accordance with the Order, further steps are being taken to identify and minimize source(s) of toxicity.

1016107 10/04/2016 CTOX Chronic Toxicity Monthly Average limit is 16.5 TUc and reported value was 40 TUc at M-001. A Toxicity Investigation Evaluation (TIE) is being conducted in conformance with the Order and the approved Toxicity Reduction Evaluation (TRE) Plant. The TIE includes investigative toxicity testing to identify the source of the toxicity that is causing the effects observed in the urchin fertilization test. During the months of September and October, the plant operator conducted mapping of various discharge stream configurations and collected a set of grab samples representing these configurations. Split samples were sent to the toxicity laboratory and the analytical laboratory for testing. The analytical laboratory ran a scan of trace elements, volatile and semi-volatile organic compounds. The toxicity laboratory is using various treatment methods for the samples and analyzing treated samples for toxicity in an effort to identify constituent(s) contributing to elevated toxicity.
