DCPP-RWMP 2013 Annual Report

1.0 Introduction

Monitoring of the marine environment near the Diablo Canyon Power Plant (DCPP) is required by WDR Order No. 90-09 (National Pollutant Discharge Elimination System (NPDES) Permit No. CA000375 1), as revised in a letter from the Central Coast Regional Water Quality Control Board in December 1998. Changes in the marine environment in the vicinity of DCPP (Figure 1)are monitored by the Receiving Water Monitoring Program (RWMP) in accordance with the NPDES Permit.This report presents seawater temperature and biological data collected in 2013 from the program's intertidal and subtidal monitoring tasks (Table 1). The sampling methods for each task are described, and the results are presented in the report's appendices.

The biological monitoring tasks were completed at fixed stations in areas that experience increased seawater temperatures from the DCPP thermal discharge, and in areas outside the influence of the discharge (Table 1). With the exception of the habitat-forming kelp survey task, the sampling frequency for the tasks was four surveys per year. A survey consisted of sampling several locations (stations) over a period of time, which varied depending on logistics, staffing resources, weather, sea state, and tide conditions.

The survey date listed in the appendix tables for any particular task represents the mean date of the time period the stations were sampled for that survey. All monitoring tasks and surveys were completed in 2013 as planned.This report does not include analysis or discussion of the results of the biological or temperature monitoring.

Comprehensive analyses of changes in the marine environment resulting from the DCPP discharge have been presented in Tenera (1988, 1997, 1999a, 1999b, 2002).ESL02014-002 PG&E

1.0 Introduction

Figure 1. Location of the Diablo Canyon Power Plant./j ESLO2014-002 PG&E -DCPP-RWMP 2013 Annual Report 3 2.0 Temperature Monitoring 2.0 Temperature Monitoring Intertidal and subtidal seawater temperatures were recorded at permanent stations located along the Diablo Canyon coastline.

Temperature units at intertidal stations were located along the rocky shore at the +0.6 m (+2.0 ft) mean lower low water (MLLW) elevation (Figure 2).Subtidal temperature recorders were located at depths from -3 m to -6 m (-10 ft to -20 ft) MLLW (Figure 3). The naming designation of individual stations reflects the area location and station number, and for the subtidal stations includes the station's depth relative to MLLW (e.g., NDC 1-3 m is north Diablo Cove subtidal Station I at a depth of-3 m MLLW).The following 13 stations were located in Diablo Cove, and were contacted regularly by the discharge plume: Intertidal:

NDC 1, NDC 2, NDC 3, SDC 1, SDC 2, SDC 3, SDP 1, and SDP 2.Subtidal:

NDC 2 -3m, NDC 3 -3m, NDC 4 -4m, SDC 1 -3m, and SDC 4 -4m.The following four stations were located in Field's Cove, approximately one kilometer upcoast from Diablo Cove, and were contacted intermittently by the discharge plume: Intertidal:

FC 1, FC 2, and FC 3.Subtidal:

FC I -3m.The following six control stations measured ambient ocean temperatures at locations beyond the influence of the discharge:

Intertidal:

NC 2, SC 1, and SC 1V.Subtidal:

NC 1 -3m, SC 1 -3m, and SC 2 -6m.Each instrument synchronously logged temperatures every 20 minutes throughout its deployment period. Instrument precision was 0.025'C with an accuracy of +/- 0.05'C. Temperature units were deployed at a station for approximately 60-90 days and then exchanged with a serviced, calibrated unit. Intertidal temperature units recorded water temperatures only when tide levels were higher than about +0.6 m MLLW. Air temperatures were removed from the database by matching the temperature records with the times that the tide level dropped below +0.6 m MLLW, using a tidal height database derived from NOAA tide gauges at Morro Bay and Port San Luis.Seawater temperatures recorded at the intertidal and subtidal temperature monitoring stations in 2013 are presented in Appendix A and Appendix B, respectively.

Below is a summary of seawater temperatures recorded in the year, based on data from a subset of the temperature recording stations in the control areas, north Diablo Cove, south Diablo Cove, and Field's Cove.ESLO2014-002 PG&E ° DCPP-RWMP 2013 Annual Report 4 2.0 Temperature Monitoring Intertidal monthly mean, maximum, and minimum temperatures recorded in 2013 at the +0.6 m (+2.0 ft) (MLLW) elevation at stations in South Control (SC 1), south Diablo Cove (SDC 1), north Diablo Cove (NDC 2), and Field's Cove (FC 2) are shown in Figure 4a. Monthly mean ambient seawater temperatures at the South Control station ranged from a low of 1 .0°C (51.8°F) in February and April to a high of 13.8°C (56.8°F) in October. Intertidal seawater temperatures were generally warmest at the Diablo Cove stations in late summer-early fall.Compared to the control station, intertidal seawater temperatures averaged 4.5°C (8.1°F) warmer in south Diablo Cove and 4.3 0 C (7.7°F) warmer in north Diablo Cove. Intertidal seawater temperatures at the Field's Cove station were 1.3°C (2.3°F) warmer than the control station, on average.Subtidal monthly mean, maximum, and minimum temperatures recorded in 2013 at -3 m MLLW in South Control (SC I -3m), south Diablo Cove (SDC 1 -3m), north Diablo Cove (NDC 2 -3m), and Field's Cove (FC 1 -3m) are shown in Figure 4b. Monthly mean ambient seawater temperatures at the South Control station ranged from a low of 11 .0C (51.8°F) in April to a high of 13.8°C (56.8°F) in October. Subtidal temperatures were generally warmest at the Diablo Cove stations in summer-early fall. Compared to the control station, subtidal temperatures averaged 3.0°C (5.4°F) warmer in south Diablo Cove and 4.3°C (7.7°F) warmer in north Diablo Cove.Subtidal temperatures at the Field's Cove station were I.I°C (2.0°F) warmer than the control station on average.DCPP typically operates at full capacity, but there were several periods in 2013 when one or two of the four main circulating water pumps (CWP) were not in service because of scheduled and unscheduled outages or curtailments.

This resulted in lower volumes of heated seawater flowing into Diablo Cove. These periods can be seen in Figure 5, and include such activities as the curtailment of Unit 1 on June 26-28 to repair a boric acid leak, a Unit 2 outage on July 10-12 to repair a damaged transformer, and the cleaning of biofouling from the walls of the Unit 1 cooling water conduits during the period from October 27 through November 2. During the brief leak repair curtailment and transformer maintenance outage, and the cooling water conduit cleaning curtailment, only one of the two affected unit's circulators remained in service. During the 2R17 refueling outage that ran from February 3 through March 23, both of the CWPs for Unit 2 were out of service. This resulted in the total volume of heated seawater flowing into Diablo Cove being reduced by approximately one-half during this period.ESLO2014-002 f"mV PG&E -DCPP-RWMP 2013 Annual Report 5 2.0 Temperature Monitoring North Control Lion Rock Field's Cove Diablo Rock NDC 1 Diablove SIDP I Cv SDP 2 Intake Cove Point San Luis \South Control (Patton Cove.Figure 2.

DCPP-RWMP 2013 Annual Report 8 3.0 Intertidal Algae and Invertebrates 3.0 Intertidal Algae and Invertebrates Intertidal algae, seagrasses, and invertebrates were sampled using the horizontal band transect (HBT) sampling method at the locations shown in Figure 6. Most HBT stations consisted of two 30 m long transects oriented parallel to the waterline, one at the +0.9 m (+3 ft) MLLW tide level and the other at the +0.3 m (+I ft) MLLW tide level. Stations SDP 1 and SDP 2 each consisted of one transect at the +0.9 m tide level. The substrate at the +0.9 m MLLW level at Station SDC I was mainly uncolonized cobble. Therefore, the upper transect at that station was located at a lower elevation at the +0.6 m MLLW tide level, and on bedrock where intertidal species were more abundant.

The sampling area of each transect consisted of ten 1.0 m 2 permanent quadrats.

The quadrats were mainly located on bedrock and boulders, but various amounts of cobble and sand that occurred seasonally were also sampled. Three control stations were located beyond the range of thermal discharges from DCPP, while the remaining 11 stations in Field's Cove, Diablo Cove, and on South Diablo Point (south headland of Diablo Cove) received varying levels of contact with warm water from the discharge.

Locations of horizontal band transect stations.In sampling, visual estimates of percent cover were made for all algal species, seagrasses, and bare substrate.

Overstory species were sampled first for coverage estimates, and then the overstory branches and blades were moved aside to allow estimation of the percent cover of the understory species and bare substrates.

Species that occupied less than 0.7% of the area of the I ESLO2014-002 PG&E e DCPP-RWMP 2013 Annual Report 9 3.0 Intertidal Algae and Invertebrates quadrat were recorded as 'present'.

Total algal cover plus bare substrate cover almost always exceeded 100 percent in a quadrat, due to overlapping layers of multiple plant taxa.Intertidal invertebrates Were sampled concurrently in the same quadrats as the algae. In five of the ten quadrats, all species were recorded as either present or absent, except individuals that were larger than 2.5 cm (1 in) in greatest dimension, which were counted. In the remaining five quadrats ('count quadrats'), the same method was used except that select species of invertebrates were counted regardless of size. The percent cover of sessile invertebrates, such as sponges and tunicates, was estimated using the same methods used for the algae. All invertebrates, algae, and seagrasses were identified to the lowest taxonomic level practical.

Black abalone of all sizes were counted in the ten permanent quadrats and in five additional quadrats on each transect.The survey mean and standard deviation, and annual mean abundance for each taxon at each transect level are presented in Appendix C. Survey statistics for algae and substrates were calculated from all ten quadrats along the transect, while statistics for the invertebrates were calculated from the five 'count' quadrats.

If a taxon was only recorded as present in a quadrat, its abundance was given a value of 0.000001 for calculating summary statistics.

ESL02014-002 PG&E -DCPP-RWMP 2013 Annual Report 10 4.0 Intertidal Fishes 4.0 Intertidal Fishes Intertidal fishes were sampled using the Vertical Band Transect (VBT) sampling method. At each of five stations (Figure 7), three transects were positioned perpendicular to the shoreline at fixed locations.

Each transect originated in the high intertidal zone (approximately

+1.5 m MLLW) and terminated in the low intertidal zone (approximately

-0.2 m MLLW). Transects at each station were separated by approximately 3 m. Each transect was used as a reference line to position twelve 1.0 m 2 permanent sampling quadrats, for a total of thirty-six 1.0 m 2 quadrats per station. Two control stations were located beyond the range of thermal discharges from DCPP, while the remaining three stations in Field's Cove and Diablo Cove received varying amounts of warm water influence from the discharge.

In sampling, moveable rocks were carefully lifted and any fishes seen were captured in small hand nets. Foliose algae were also searched for cryptic fishes. Fishes were identified to the lowest practical taxonomic level, measured, and returned to the quadrat following sampling.Newly settled juvenile fishes were not identified to the species level but were grouped into composite taxa (e.g., Pholididae/Stichaeidae, Anoplarchus/Cebidichthys).

The total numbers observed at each station during the four surveys of the year, and annual mean abundance and standard deviation of fishes for each taxon are presented in Appendix D.North Control NC IV Lion Rock r Field's Cove Diablo Rock,.

DCPP-RWMP 2013 Annual Report 11 5.0 Subtidal Algae and Invertebrates 5.0 Subtidal Algae and Invertebrates Eight permanent subtidal benthic sampling stations located in depths ranging from -3 m to -6 m (-10 ft to -20 fi) MLLW were sampled during the year (Figure 8). Two control stations were located in Patton Cove, beyond the range of thermal discharges from DCPP, while the remaining six stations received varying amounts of warm water influence from the discharge.

Stations were circular with a radius of 3.15 m and a sampling area of 28.0 m 2.The center 3.1 mi 2 of each station, which surrounded a mooring anchor (railcar wheel), was not sampled in order to avoid any unnatural algal and invertebrate growth associated with the mooring. Each station was divided into four equal sections, or 'arc quadrants', 7.0 m2 in area. All stations were established primarily on substrates of mixed bedrock and boulders with small amounts of cobble and sand.Divers used three sampling methods at each station to sample the benthic algae and invertebrates.

In the first method, individual species of kelp (brown algae of the order Laminariales and Fucales) and macroinvertebrates were counted in each subtidal arc quadrant (SAQ sampling method). Kelp plants and individuals of select invertebrate taxa were counted regardless of their size. Individuals of other non-encrusting invertebrates were counted if they were larger than 2.5 cm (1.0 in) (length or width). Juvenile kelp plants that could not be identified to the species level were counted and recorded as 'Laminariales.'

Five common species that generally occurred in numbers too high to accurately count in a large area were sampled in the same one-third area (2.33 m 2) of each quadrant, each survey. The count for each of these species was multiplied by three to provide an abundance estimate for the entire quadrant.In the second sampling method (subtidal line contact or SLC) all understory algal species were quantified at the stations as percent cover using a series of pre-selected random points. A radius line with ten lead markers positioned at decreasing intervals toward the station perimeter was attached to the center of the station and used to locate sampling loci in each quadrant.

Fifty random contact points were sampled within each quadrant (total of 200 points per station), and the same pre-selected set of points was used at all stations.

Random sampling points were changed for each survey. The presence of all algal species, sessile invertebrates, and substrates observed directly under or over the points was recorded.

Holdfasts of kelp species were also included when contacted by the sample points. The percent cover of each species and substrate type was calculated by dividing the number of 'contacts' by the number of points sampled. All algal species on the station were identified to the lowest taxonomic level practical.

In each quadrant, algal species that were present but not contacted by the sample points were noted separately as being 'present' in the quadrant.In the third method, invertebrates were sampled using the subtidal fixed quadrat (SFQ) method in four permanent circular 0.25 m 2 quadrats at each station. The method quantified species composition and abundance of all invertebrate taxa visible to the naked eye. One permanent quadrat was located within each of the four SAQ quadrants, generally on bedrock or boulder substrate.

Depending upon the degree of topographical relief, two quadrats were located onESL02014-002 PG&E

DCPP-RWMP 2013 Annual Report 12 5.0 Subtidal Algae and Invertebrates horizontal-aspect surfaces and two quadrats were located on vertical-aspect surfaces.

All non-encrusting taxa were identified and counted. The coverage of encrusting taxa (e.g., colonial/social tunicates) was quantified in square inch units if the total equaled or exceeded 1 square inch (6.5 cm2). Otherwise, the encrusting taxon was recorded as 'present'.

The survey mean and standard deviation for each taxon at each station from the four surveys completed during the year are presented in Appendices E (SAQ), F (SLC), and G (SFQ). The means are based on the data from the four quadrats or quadrants at each station. The tables also list annual mean taxa abundances by station based on the average of all surveys sampled over the year. Algal taxa in the SLC study, and encrusting taxa in the SFQ study, that were recorded as only present (no numeric value) were given a value of 0.000001 for calculating abundance statistics.

This task has been completed annually since the 1970s to document long-term changes in the annual maximum extent of the surface kelp canopies in Diablo Cove. Near the end of the annual growth cycle in October, nearly all bull kelp plants have reached the surface and can be counted. Surface canopies of giant kelp also tend to be abundant during this period. Two observers at the headland of north Diablo Cove and two observers at the headland of south Diablo Cove (south Diablo Point) counted and mapped the distribution of individual bull kelp plants and mapped the spatial extent of giant kelp canopies (Figure 9). Bull kelp plants with bare bulbs only and no attached fronds, indicating senescence in the plants, were noted when possible.The annual habitat-forming kelp survey was conducted on October 1, 2013. No bull kelp plants were observed in Diablo Cove during the survey; giant kelp canopies occurred in both north and south Diablo Cove (Figure 9). There are no appendix figures or data tables associated with this task.0~0.25 Mthe 0 SO0.Figure 9. Map of surface kelp in Diablo Cove on October 1, 2013.0 ESLO2014-002 PG&E

DCPP-RWMP 2013 Annual Report 14 7.0 Subtidal Fishes 7.0 Subtidal Fishes Visual counts of fishes were conducted by divers at 12 permanent subtidal stations (three stations in each of four areas) located within and outside of Diablo Cove (Figure 10). Three control stations located in Patton Cove were beyond the range of thermal discharges from DCPP, while the remaining nine stations in Field's Cove, north Diablo Cove, and south Diablo Cove received varying amounts of warm water influence from the discharge.

Each station consisted of a benthic transect 50 m long by 4 m wide by 1 m above the bottom, and a 50 m long by 4 m diameter midwater transect located above and parallel to the benthic transect approximately midway between the surface and the bottom. A station was sampled by first deploying a fiberglass measuring tape to delineate the centerline of the benthic transect, beginning at a permanent station buoy and extending 50 m away from the buoy along a pre-determined compass course. Some transects crossed over each other where a transect parallel to the depth contour crossed over a transect positioned perpendicular to the depth contour. The area common to both transects in these cases was approximately 2%. This small overlap did not affect the data summaries because the numbers of fish counted were averaged by area, and the mobility of most fish added to the independence of transects.

/j' ESLO2014-002 PG&E -DCPP-RWMP 2013 Annual Report 15 7.0 Subtidal Fishes A survey team consisted of two divers. Each diver counted fish along the benthic and midwater transect sampling areas, swimming in opposite directions along the transects.

This sampling technique allowed a more thorough inspection of potential fish habitats from all angles of view than would have been possible by a single diver progressing along a transect in only one direction.

Fish were identified to species if possible, but juveniles of some species with similar appearances were combined into broader categories if necessary.

The resulting survey data per transect were the combined species counts of both divers, divided by two. This yielded an average count for each taxon per 50 m by 4 m benthic transect and per 50 m long by 4 m diameter midwater transect.

During each survey, the stations (midwater and benthic transects) were usually sampled a second time (replicate

2) within two weeks of the initial sampling effort (replicate 1), unless adverse sea conditions precluded a second replicate.

The replicate 1 and 2 data per area were pooled separately for the three midwater transects and the three benthic transects for each survey.The survey mean abundance and standard deviation for each taxon within each of the four sampling areas for the four surveys during the year are presented in Appendix H. The tables are further divided according to midwater and benthic transects in each area. The tables also show overall mean abundances for the entire year. The survey dates shown for each area in the tables represent the average date of the combined stations sampled in replicates 1 and 2.__,ESLO2014-002 PG&E -DCPP-RWMP 2013 Annual Report 16 8.0 Project Personnel 8.0 RWMP Project Personnel Project Personnel 2013 Tenera Environmental Principal Investigator Project Manager: Project Scientists:
