Analytical results below the respective analytical detection limit (ND or non-detect) are plotted as a "zero" value in accordance with ELAP guidance.
Results between the analytical detection limit and reporting (quantitation) limits are plotted at the value and shown as 'DNO' in the tabular summaries as is done for CIWQS reports. Less-than results are typically reported to express an average of values that include non-detects and at least one result greater than the 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 discharge stream. The substances listed in Table B in the California Ocean Plan were each analyzed for and reported in the permit renewal application and application updates for Diablo Canyon Power Plant (DCPP) submitted in October 1994, January 2001, and April 2011. There have been no changes in activities conducted at the plant that would have significantly affected the results previously reported in the above referenced documents.
SUMMARY
OF MONITORING PROGRAM A. Monitoring of Plant Influent and Effluent 1. Monitoring Data a. Appendix 1 provides a list of discharge path names for ease of reference.
Appendix 2 contains monitoring 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 sample quantities occurred from pathway 016, and no discharge occurred from pathway 017 during 2014.005 DNQ(2.6) mg/I 008 non-detect
-ND(1 .4 mg/I)009 DNQ(2.5) mg/I 013 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 for lithium, 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 Manual Pacific Gas and Electric Company (PG&E) maintains a multiple volume Plant Manual at DCPP that contains procedures used for operation and maintenance activities at the plant, including those activities that relate to wastewater handling, treatment, sampling, analysis and discharge.
Plant procedures are prepared and reviewed by DCPP Staff and approved by Plant Management.
The facility 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 plant procedures are conducted to assure that the manual remains valid, current, and complete for the facility.I
- 3. Laboratories Used to Monitor Compliance The following laboratories were used during 2014 for monitoring compliance.
The laboratories are certified by appropriate agencies for the. tests/analyses performed.
As part of the on-going annual certification process, these laboratories take part in annual performance evaluation testing.a.

Review of Compliance Record and Corrective Actions a: Circulating Water Chlorination/Bromination Monitoring The 2,014 quarterly NPDES reports discuss chlorination cycles when discharge monitoring was interrupted.
These events are listed below, with brief descriptions of the cause and respective corrective action. When these monitoring interruptions occurred, engineering evaluations were performed (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 ofj Date Readings Affected jCause Corrective Action 03/11114 to Unit I Faulted circuit board 03/19/14 13 Readings in discharge monitor.Cictborreled 04/07/14 to Unit 2Losapefo.Fwrsted 04108/14 5 ReadingsLosapefw.Fwrsted 05/14/14 to Unit 2 Quality control check result > Monitor calibrated.

- b. Closed Cooling Water Releases During 2014, maintenance activities that required draining of closed cooling water systems were performed, and are summarized below. PG&E received concurrence from the CCRWQCB in response 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 and isothiazolin to control microbiological growth and corrosion in DCPP's freshwater closed cooling water systems. Any drainage from these systems is discharged at a flow-rate such that the chronic toxicity level 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), service cooling water (SCW), and intake cooling water (ICW) systems are presented below. The*glutaraldehyde (Glut) and isothiazoline (Iso) concentrations presented in the table are system concentrations, not concentrations at the point of discharge to receiving water. The dates/drain-events highlighted with an asterisk (*) Were inadvertently omitted from the table provided in the 1st Quarter 2014 discharge self-monitoring report, and is listed in the Errata section of this Volume Glut Iso Ttl Ol&Reason

- c. Sample Analysis Issues 1. One sample taken for the 2014 second quarter was mistakenly incorporated into the third quarter metals composite sample for Discharge 001 H. This unused sample aliquot from the Unit I Condensate Regeneration System obtained on 06/24/14 was inadvertently added to the discharge pathway composite being prepared for third quarter analysis.
The presence of this sample aliquot in the 001 H composite is reflected on the ClWQS application submittal Attachment 1 Worksheet I for Unit 1 Location 001 H. It is unlikely the single inadvertently added aliquot significantly impacted the composite sample metals constituent analysis.B. Monitoring of Receiving Water 1. Ecological Studies at Diablo Canyon Marine 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, 1999 3 (DCL-99-503).
This program includes tasks from the Ecological Monitoring Program (EMP) with additional stations and increased sampling frequencies.
This program replaces the EMP and the Thermal Effects Monitoring Program (TEMP). Several one-year-only tasks outlined in the above letters were completed in 1999 and were not requested to be performed in 2014. Results of 2013 RWMP data were submitted to the CCRWQCB on April 29, 2014. A table in Appendix 4 summarizes requirements and completed monitoring tasks for 2014.2. In Situ Bioassay Results of the Mussel Watch Program are reported to the CCRWQCB directly by the California Department of Fish and Wildlife (CDF&W) in the agency's periodic report for this program.C. Sodium Bromide Treatment Program DCPP continued an integrated sodium bromide and "foul release coating" strategy to control macrofouling in the Circulating Water System (CWS). Both circulating water conduits of each Unit can be chemically treated simultaneously.
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 intake conduits.
In July 2014, DCPP returned to the use of a proprietary NALCO sodium bromide mix (Acti-Brom) to replace the generic sodium bromide to enhance marine biofouling control effectiveness.
Each injection attempts to achieve a target concentration of 300 parts per billion (ppb) Total Residual Oxidant (TRO) at the inlet waterbox of the main steam condensers.
Discharge TRO, measured at the plant outfall, remained below NPDES 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 previously painted 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 hypochlorite six times a dlay through January with a brief interruption for maintenance activities.
Unit 1 injections were secured 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 through June 2014 with brief interruptions in late March, and May for maintenance activities.
Biofoufing treatment continued with simultaneous injections of Acti-Brom and sodium hypochlorite from July through the remainder of 2014 with brief interruptions in August, and October for equipment maintenance activities.
Injections were also 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 hypochlorite six times a clay through most of the first half of 2014. Injections were shut down for several days in January for a scheduled seawater conduit cleaning.
Simultaneous injections of sodium bromide and sodium hypochlorite resumed after the cleaning and continued through June with brief interruptions in February, March, and May due to maintenance activities.
Biofouling treatment continued with simultaneous injections of Acti-Brom and sodium 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 and maintenance outage. Sodium hypochlorite injections continued through the remainder of September for microfouling 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 with simultaneous injections of Acti-Brom and sodium hypochlorite six times a day from early November throughout the remainder of 2014, with one brief interruption in early December for equipment maintenance activities.
