Analytical results belowthe respective analytical detection limit (ND or non-detect) are plotted as a "zero" value in accordance withELAP guidance. Results between the analytical detection limit and reporting (quantitation) limits are plotted atthe value and shown as 'DNO' in the tabular summaries as is done for CIWQS reports. Less-than results aretypically reported to express an average of values that include non-detects and at least one result greater thanthe respective reporting limit (RL). These less-than results are plotted conservatively at the RL. During 2014,discharges occurred from all discharge paths except 0011, 001K, 016, and 017.California Ocean Plan Table B] substances that were not analyzed for have not been added to the dischargestream. The substances listed in Table B in the California Ocean Plan were each analyzed for and reported inthe permit renewal application and application updates for Diablo Canyon Power Plant (DCPP) submitted inOctober 1994, January 2001, and April 2011. There have been no changes in activities conducted at the plantthat would have significantly affected the results previously reported in the above referenced documents.SUMMARY OF MONITORING PROGRAMA. Monitoring of Plant Influent and Effluent1. Monitoring Dataa. Appendix 1 provides a list of discharge path names for ease of reference. Appendix 2 containsmonitoring data in tabular form. Appendix 3 contains monitoring data in graphical form.b. Annual oil and grease analyses were performed in October on Stormwater/Yard Drain Discharges 005,008, 009, 013, and 015. Results are listed below. No discharges that resulted in adequate samplequantities occurred from pathway 016, and no discharge occurred from pathway 017 during 2014.005 DNQ(2.6) mg/I008 non-detect -ND(1 .4 mg/I)009 DNQ(2.5) mg/I013 non-detect -ND(1.4 mg/I)015 non-detect -ND(1.4 mg/I)c. In October, Discharge 001 D (Liquid Radioactive Waste Treatment System) annual grab samples forlithium, boron, and hydrazine were collected and analyzed. The results were ND(0.050 mg/I), 273 mg/I,and ND(0.003) mag/I, respectively.2. Facility Operating and Maintenance ManualPacific Gas and Electric Company (PG&E) maintains a multiple volume Plant Manual at DCPP thatcontains procedures used for operation and maintenance activities at the plant, including those activitiesthat relate to wastewater handling, treatment, sampling, analysis and discharge.Plant procedures are prepared and reviewed by DCPP Staff and approved by Plant Management. Thefacility conducts biennial internal audits that review NPDES procedures contained in the plant manual, as* well as procedure implementation adherence by responsible workgroups. Ongoing reviews of plantprocedures are conducted to assure that the manual remains valid, current, and complete for the facility.I

Review of Compliance Record and Corrective Actionsa: Circulating Water Chlorination/Bromination MonitoringThe 2,014 quarterly NPDES reports discuss chlorination cycles when discharge monitoring wasinterrupted. These events are listed below, with brief descriptions of the cause and respectivecorrective action. When these monitoring interruptions occurred, engineering evaluations wereperformed (as approved by the CCRWQCB January 13, 1994; PG&E Letter No. DCL-94-002).Descriptions of these evaluations are included in the respective quarterly reports as applicable.The evaluations concluded that discharge chlorine limits were not exceeded during these events.Unit and Number ofjDate Readings Affected jCause Corrective Action03/11114 to Unit I Faulted circuit board03/19/14 13 Readings in discharge monitor.Cictborreled04/07/14 to Unit 2Losapefo.Fwrsted04108/14 5 ReadingsLosapefw.Fwrsted05/14/14 to Unit 2 Quality control check result > Monitor calibrated.05/21/14 0 Readings upper acceptance limit.07/21/14 to Unit 2 Monitor upper flow Flow block replaced and monitor08/01/14 30 Readings block biofouling. recalibrated.07/3014 to Unit 1 Monitor upper flow Flow block replaced and monitor08/06/14 7 Readings block biofouling. recalibrated.10/15/14 to Unit 1 Monitor sample valve10/16/14 6 Readings inadvertently mispositioned Valve repositioned.11/17/14 to Unit 2 Moio apefo sltd Temperature element mount11/20/14 21 Readings during repair of temperature repair completed.element mount in same pipe.______________11/26/14 to Unit 2 Mntroe-epnig oio eairtd12/03/14 0 Readings Mntroe-epnig oio eairtd72
- b. Closed Cooling Water ReleasesDuring 2014, maintenance activities that required draining of closed cooling water systems wereperformed, and are summarized below. PG&E received concurrence from the CCRWQCB inresponse to letters dated July 19, 1995 (PG&E Letter DCL-95-156), May 23, 1996 (PG&E Letter DCL-96-522), and May 19, 1997 (PG&E Letter DCL-97-533) regarding the use of glutaraldehyde andisothiazolin to control microbiological growth and corrosion in DCPP's freshwater closed cooling watersystems. Any drainage from these systems is discharged at a flow-rate such that the chronic toxicitylevel is below the "No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.The volumes of cooling water drained in 2014 from the component cooling water (CCW), servicecooling water (SCW), and intake cooling water (ICW) systems are presented below. The*glutaraldehyde (Glut) and isothiazoline (Iso) concentrations presented in the table are systemconcentrations, not concentrations at the point of discharge to receiving water. The dates/drain-eventshighlighted with an asterisk (*) Were inadvertently omitted from the table provided in the 1st Quarter2014 discharge self-monitoring report, and is listed in the Errata section of this Volume Glut Iso Ttl Ol&Reason &Date SysemnTota Grels&at Sytm (gallons) (rag/I) (mg/I) SusenddeGeas_________ _________ _____Solids (mgll) .(mgf,), Cmet01/08/14 Unit 2 SCW 50 0.0 8.2 n/a n/a Routine Maintenance01/21/14 (*) Unit 2SCW 33,110 0.0 8.2 < 2.0 < 1.4 Routine Maintenance02/08114 Unit I ICW 1,;150 0.0 2.8 < 2.0 < 1.4 Routine Maintenance02/11/114 Unit I SCW 9,500 0.0 7.2 n/a n/a Routine Maintenance02/14/14 Unit 1 CCW 831 174 0.0 n/a n/a Routine Maintenance02/25/14 (*) Unit 1 CCW 25 n/a n/a 164 -n/a Routine Maintenance04/115/14 Unit 1 14 0.0 1.9 n/a n/a Routine Maintenance04/15/14 unit 2 lCW 14 0.0 1.8 n/a n/a Routine Maintenance04/16/14 Unit I CCW 3,800 153 0.0 < 2.0 < 1.4 Routine Maintenance05/14/14 Unit I SCW 550 0.0 8.6 n/a n/a Routine Maintenance06/08/14 Unit I ICW 14 0.0 1.6 n/a n/a Routine Maintenance06/24/14 Unit 1 SCW 33,100 0.0 8.3 < 2.0 Negative Routine Maintenance10/08/14 Unit 2 SCW 5,100 0.0 7.9 6.5 < 1.4 Routine Maintenance10/16/14 Unit 1 SCW 10 0.0 6.9 n/a n/a Routine Maintenance11/09/14 Unit 2 lCW 3,321 0.0 6.5 n/a n/a Routine Maintenancec. Sample Analysis Issues1. One sample taken for the 2014 second quarter was mistakenly incorporated into the third quartermetals composite sample for Discharge 001 H. This unused sample aliquot from the Unit ICondensate Regeneration System obtained on 06/24/14 was inadvertently added to the dischargepathway composite being prepared for third quarter analysis. The presence of this sample aliquotin the 001 H composite is reflected on the ClWQS application submittal Attachment 1 Worksheet Ifor Unit 1 Location 001 H. It is unlikely the single inadvertently added aliquot significantly impactedthe composite sample metals constituent analysis.B. Monitoring of Receiving Water1. Ecological Studies at Diablo CanyonMarine ecological monitoring was continued during 2014 under the Receiving Water Monitoring Program(RWMP) as requested in a letter from the Central Coast Regional Water Quality Control Board(CCRWQCB) dated December 9, 1998, and as detailed in a letter from PG&E dated January 8, 19993 (DCL-99-503). This program includes tasks from the Ecological Monitoring Program (EMP) with additionalstations and increased sampling frequencies. This program replaces the EMP and the Thermal EffectsMonitoring Program (TEMP). Several one-year-only tasks outlined in the above letters were completed in1999 and were not requested to be performed in 2014. Results of 2013 RWMP data were submitted to theCCRWQCB on April 29, 2014. A table in Appendix 4 summarizes requirements and completed monitoringtasks for 2014.2. In Situ BioassayResults of the Mussel Watch Program are reported to the CCRWQCB directly by the California Departmentof Fish and Wildlife (CDF&W) in the agency's periodic report for this program.C. Sodium Bromide Treatment ProgramDCPP continued an integrated sodium bromide and "foul release coating" strategy to control macrofouling inthe Circulating Water System (CWS). Both circulating water conduits of each Unit can be chemically treatedsimultaneously. For the first half of 2014, the treatment program consisted of six 20-minute injections (at 4-hour intervals) of a blend of generic sodium bromide and sodium hypochiorite into the plant seawater intakeconduits. In July 2014, DCPP returned to the use of a proprietary NALCO sodium bromide mix (Acti-Brom) toreplace the generic sodium bromide to enhance marine biofouling control effectiveness. Each injectionattempts to achieve a target concentration of 300 parts per billion (ppb) Total Residual Oxidant (TRO) at theinlet waterbox of the main steam condensers. Discharge TRO, measured at the plant outfall, remained belowNPDES limitations. Typically, discharge TRO values during treatment were between 20 ppb and 50 ppb.In conjunction with the chemical treatment, untreated portions of the cooling water system were previouslypainted with a non-toxic "foul release coating" to reduce or prevent attachment of fouling organisms.Both conduits of Unit 1 were treated with simultaneous injections of sodium bromide and sodium hypochloritesix times a dlay through January with a brief interruption for maintenance activities. Unit 1 injections weresecured in early February for the scheduled 1R18 unit refueling and maintenance outage. Simultaneous*injections of sodium bromide and sodium hypochlorite were'restarted in mid-March, and continued throughJune 2014 with brief interruptions in late March, and May for maintenance activities. Biofoufing treatmentcontinued with simultaneous injections of Acti-Brom and sodium hypochlorite from July through the remainderof 2014 with brief interruptions in August, and October for equipment maintenance activities. Injections werealso secured in early December for several days for a Unit 1 tunnel cleaning.*Both conduits of Unit 2 were treated with simultaneous injections of sodium bromide and sodium hypochloritesix times a clay through most of the first half of 2014. Injections were shut down for several days in January fora scheduled seawater conduit cleaning. Simultaneous injections of sodium bromide and sodium hypochloriteresumed after the cleaning and continued through June with brief interruptions in February, March, and Maydue to maintenance activities. Biofouling treatment continued with simultaneous injections of Acti-Brom andsodium hypochlorite from July through August with two brief interruptions in August for maintenance activities.Acti-Brom injections were secured in mid-September in anticipation of the scheduled 2R1 8 unit refueling andmaintenance outage. Sodium hypochlorite injections continued through the remainder of September formicrofouling control in the Unit 2 main steam condenser. Unit 2 chemical injections were secured from early'October to early November for the 2R1 8 refueling outage. Both conduits of Unit 2 were treated withsimultaneous injections of Acti-Brom and sodium hypochlorite six times a day from early November throughoutthe remainder of 2014, with one brief interruption in early December for equipment maintenance activities.D. ErrataThree quarterly r'eporting errors have been identified while compiling and verifying data for this annual report.In the 1st quarter 2014 discharge self-monitoring report in the Overview section, item 3, a Unit 2 SCW closedcooling system drain/release on January 21, 2014 was inadvertently left out. The data is included in thesummary table above. The amount of wastewater released was 33,110 gallons.4 In the ist quarter 2014 discharge self-monitoring report in the Overview section, item 3, a Unit 1 CCW closedcooling system drainlrelease on February 25, 2014 was inadvertently left out. The data is included in thesummary table above.
