DCPP-RWMP 2013 Annual Report

1.0 Introduction

Monitoring of the marine environment near the Diablo Canyon Power Plant (DCPP) is requiredby WDR Order No. 90-09 (National Pollutant Discharge Elimination System (NPDES) PermitNo. CA000375 1), as revised in a letter from the Central Coast Regional Water Quality ControlBoard 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 theNPDES Permit.This report presents seawater temperature and biological data collected in 2013 from theprogram's intertidal and subtidal monitoring tasks (Table 1). The sampling methods for eachtask 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 theinfluence 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 samplingseveral locations (stations) over a period of time, which varied depending on logistics, staffingresources,

weather, sea state, and tide conditions.

The survey date listed in the appendix tablesfor any particular task represents the mean date of the time period the stations were sampled forthat 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 theDCPP 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 Report3 2.0 Temperature Monitoring 2.0 Temperature Monitoring Intertidal and subtidal seawater temperatures were recorded at permanent stations located alongthe Diablo Canyon coastline.

Temperature units at intertidal stations were located along therocky 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 stationnumber, 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 thedischarge plume:Intertidal:

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 upcoastfrom 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 theinfluence 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 weredeployed 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 levelswere higher than about +0.6 m MLLW. Air temperatures were removed from the database bymatching the temperature records with the times that the tide level dropped below +0.6 mMLLW, using a tidal height database derived from NOAA tide gauges at Morro Bay and PortSan Luis.Seawater temperatures recorded at the intertidal and subtidal temperature monitoring stations in2013 are presented in Appendix A and Appendix B, respectively.

Below is a summary ofseawater 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 meanambient 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 seawatertemperatures 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) warmerin south Diablo Cove and 4.30C (7.7°F) warmer in north Diablo Cove. Intertidal seawatertemperatures at the Field's Cove station were 1.3°C (2.3°F) warmer than the control station, onaverage.Subtidal monthly mean, maximum, and minimum temperatures recorded in 2013 at -3 m MLLWin 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 seawatertemperatures at the South Control station ranged from a low of 11 .0C (51.8°F) in April to a highof 13.8°C (56.8°F) in October.

Subtidal temperatures were generally warmest at the Diablo Covestations in summer-early fall. Compared to the control station, subtidal temperatures averaged3.0°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 controlstation on average.DCPP typically operates at full capacity, but there were several periods in 2013 when one or twoof the four main circulating water pumps (CWP) were not in service because of scheduled andunscheduled outages or curtailments.

This resulted in lower volumes of heated seawater flowinginto Diablo Cove. These periods can be seen in Figure 5, and include such activities as thecurtailment of Unit 1 on June 26-28 to repair a boric acid leak, a Unit 2 outage on July 10-12 torepair a damaged transformer, and the cleaning of biofouling from the walls of the Unit 1 coolingwater conduits during the period from October 27 through November

2. During the brief leakrepair curtailment and transformer maintenance outage, and the cooling water conduit cleaningcurtailment, only one of the two affected unit's circulators remained in service.

During the 2R17refueling outage that ran from February 3 through March 23, both of the CWPs for Unit 2 wereout of service.

This resulted in the total volume of heated seawater flowing into Diablo Covebeing 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 ControlLion RockField'sCoveDiablo Rock NDC 1DiabloveSIDP I CvSDP 2Intake CovePoint San Luis \South Control(Patton Cove.Figure 2.

DCPP-RWMP 2013 Annual Report8 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 two30 m long transects oriented parallel to the waterline, one at the +0.9 m (+3 ft) MLLW tide leveland 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 StationSDC I was mainly uncolonized cobble. Therefore, the upper transect at that station was locatedat a lower elevation at the +0.6 m MLLW tide level, and on bedrock where intertidal specieswere more abundant.

The sampling area of each transect consisted of ten 1.0 m2 permanent quadrats.

The quadrats were mainly located on bedrock and boulders, but various amounts ofcobble and sand that occurred seasonally were also sampled.

Three control stations were locatedbeyond the range of thermal discharges from DCPP, while the remaining 11 stations in Field'sCove, Diablo Cove, and on South Diablo Point (south headland of Diablo Cove) receivedvarying 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, andbare substrate.

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

Species that occupied less than 0.7% of the area of theI 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 alwaysexceeded 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 ofthe ten quadrats, all species were recorded as either present or absent, except individuals thatwere larger than 2.5 cm (1 in) in greatest dimension, which were counted.

In the remaining fivequadrats

('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 andtunicates, was estimated using the same methods used for the algae. All invertebrates, algae, andseagrasses were identified to the lowest taxonomic level practical.

Black abalone of all sizeswere 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 eachtransect level are presented in Appendix C. Survey statistics for algae and substrates werecalculated from all ten quadrats along the transect, while statistics for the invertebrates werecalculated from the five 'count' quadrats.

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

ESL02014-002 PG&E -DCPP-RWMP 2013 Annual Report 10 4.0 Intertidal Fishes4.0 Intertidal FishesIntertidal fishes were sampled using the Vertical Band Transect (VBT) sampling method. Ateach of five stations (Figure 7), three transects were positioned perpendicular to the shoreline atfixed locations.

Each transect originated in the high intertidal zone (approximately

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

-0.2 m MLLW). Transects ateach station were separated by approximately 3 m. Each transect was used as a reference line toposition twelve 1.0 m2 permanent sampling

quadrats, for a total of thirty-six 1.0 m2 quadrats perstation.

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 ofwarm water influence from the discharge.

In sampling, moveable rocks were carefully lifted and any fishes seen were captured in smallhand nets. Foliose algae were also searched for cryptic fishes. Fishes were identified to thelowest 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 intocomposite taxa (e.g., Pholididae/Stichaeidae, Anoplarchus/Cebidichthys).

DCPP-RWMP 2013 Annual Report11 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 werelocated 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 werecircular with a radius of 3.15 m and a sampling area of 28.0 m2.The center 3.1 mi2 of eachstation, which surrounded a mooring anchor (railcar wheel), was not sampled in order to avoidany unnatural algal and invertebrate growth associated with the mooring.

Each station wasdivided 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 andinvertebrates.

In the first method, individual species of kelp (brown algae of the orderLaminariales and Fucales) and macroinvertebrates were counted in each subtidal arc quadrant(SAQ sampling method).

Kelp plants and individuals of select invertebrate taxa were countedregardless of their size. Individuals of other non-encrusting invertebrates were counted if theywere larger than 2.5 cm (1.0 in) (length or width). Juvenile kelp plants that could not beidentified to the species level were counted and recorded as 'Laminariales.'

Five commonspecies that generally occurred in numbers too high to accurately count in a large area weresampled in the same one-third area (2.33 m 2) of each quadrant, each survey. The count for eachof 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 werequantified at the stations as percent cover using a series of pre-selected random points. A radiusline with ten lead markers positioned at decreasing intervals toward the station perimeter wasattached to the center of the station and used to locate sampling loci in each quadrant.

Fiftyrandom contact points were sampled within each quadrant (total of 200 points per station),

andthe same pre-selected set of points was used at all stations.

Random sampling points werechanged 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 alsoincluded 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.

Allalgal species on the station were identified to the lowest taxonomic level practical.

In eachquadrant, algal species that were present but not contacted by the sample points were notedseparately as being 'present' in the quadrant.

In the third method, invertebrates were sampled using the subtidal fixed quadrat (SFQ) methodin four permanent circular 0.25 m2 quadrats at each station.

The method quantified speciescomposition 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 bouldersubstrate.

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 exceeded1 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 surveyscompleted during the year are presented in Appendices E (SAQ), F (SLC), and G (SFQ). Themeans are based on the data from the four quadrats or quadrants at each station.

The tables alsolist annual mean taxa abundances by station based on the average of all surveys sampled over theyear. Algal taxa in the SLC study, and encrusting taxa in the SFQ study, that were recorded asonly present (no numeric value) were given a value of 0.000001 for calculating abundance statistics.

This task has been completed annually since the 1970s todocument long-term changes in the annual maximum extent of the surface kelp canopies inDiablo Cove. Near the end of the annual growth cycle in October, nearly all bull kelp plants havereached the surface and can be counted.

Surface canopies of giant kelp also tend to be abundantduring this period. Two observers at the headland of north Diablo Cove and two observers at theheadland of south Diablo Cove (south Diablo Point) counted and mapped the distribution ofindividual bull kelp plants and mapped the spatial extent of giant kelp canopies (Figure 9). Bullkelp plants with bare bulbs only and no attached fronds, indicating senescence in the plants, werenoted when possible.

The annual habitat-forming kelp survey was conducted on October 1, 2013. No bull kelp plantswere observed in Diablo Cove during the survey; giant kelp canopies occurred in both north andsouth Diablo Cove (Figure 9). There are no appendix figures or data tables associated with thistask.0~0.25 Mthe0 SO0.Figure 9. Map of surface kelp in Diablo Cove on October 1, 2013.0 ESLO2014-002 PG&E

DCPP-RWMP 2013 Annual Report14 7.0 Subtidal Fishes7.0 Subtidal FishesVisual counts of fishes were conducted by divers at 12 permanent subtidal stations (three stationsin each of four areas) located within and outside of Diablo Cove (Figure 10). Three controlstations located in Patton Cove were beyond the range of thermal discharges from DCPP, whilethe remaining nine stations in Field's Cove, north Diablo Cove, and south Diablo Cove receivedvarying 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, anda 50 m long by 4 m diameter midwater transect located above and parallel to the benthic transectapproximately midway between the surface and the bottom. A station was sampled by firstdeploying 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 tothe depth contour crossed over a transect positioned perpendicular to the depth contour.

The areacommon to both transects in these cases was approximately 2%. This small overlap did not affectthe data summaries because the numbers of fish counted were averaged by area, and the mobilityof most fish added to the independence of transects.

/j' ESLO2014-002 PG&E -DCPP-RWMP 2013 Annual Report15 7.0 Subtidal FishesA survey team consisted of two divers. Each diver counted fish along the benthic and midwatertransect sampling areas, swimming in opposite directions along the transects.

This samplingtechnique allowed a more thorough inspection of potential fish habitats from all angles of viewthan would have been possible by a single diver progressing along a transect in only onedirection.

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

The resulting survey data per transect were the combined species counts of both divers, dividedby two. This yielded an average count for each taxon per 50 m by 4 m benthic transect and per50 m long by 4 m diameter midwater transect.

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

2) within two weeks of theinitial 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 andthe three benthic transects for each survey.The survey mean abundance and standard deviation for each taxon within each of the foursampling areas for the four surveys during the year are presented in Appendix H. The tables arefurther divided according to midwater and benthic transects in each area. The tables also showoverall mean abundances for the entire year.
