1.0 Introduction 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 monitoied

,by*:

te Receiving Water Monitoring Program (RWMP) in accordance with the NPDES Permit.

This report presents wate Itemperature and biological data collected from January: 2008 through Decemb er 2008 from the iprogram's intertidal and subtidal monitoring tasks (Table 1). All monitoring tasks were completed in 2008 as planned. This report presents the data collected during 2008, and does not include any analysis or discussion of results. Comprehensive analyses of changes-in.the marine environment resulting from the DCPP discharge have been presented in Tenera (1988, 1997, 1999a, 1999b and 26002')e77'-.)

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 aling igthe rocky shore at the +0.6 m (+2.0 ;ft) mean lower low water' (MLLW) elevation (Figure 2).

Subtidal temperature recorders were located at depthsTrom -3 m'to'-6rm (-10 ft to -20 ft) MLLW (Figure 3). Th& naming designation of individufal subtidtl stations reflects the area locationh.and number, followed by thestation depth relative to MLLW-(&-.g., NDC 1 -3m isNorth Diablo Cove subtidal Station '. lat a depth of-3 m.ML-LW)-.

The following 13 stations were, located in Diablo Cove, and were contacted regularly by the discharge plume:.

Intertidal: NDC-f, NDC-2, NDC-C

-1SDC-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 1 -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.

Water temperatures were recorded at all stations throughout the year without interruption, with the exception of a 94-day lapse in data at intertidal Station NDC 3 +0.6m. The temperature unit deployed at this station on February 5, 2008 malfunctioned, causing a loss of data between its deployment and its replacement with another unit on May 9, 2008. Temperatures at Station NDC ESL02009-006.3 PG&E

DCPP-RWMP 2008 Annual Report 3

2.0 Temperature Monitoring 3 +0.6m, located approximately 35 m upcoast from Station NDC,3 +0.6m, were recorded during this period and throughout the year.

The mean ambient monthly temperatures ranged from a low of 9.5°C (49.,!.F) at south Control in-April; to a meanmonthly high of 14.69C :(58.3'F) in ;September. Intertidal temperatures were generaJlly ;warmest in south, -Diablo: Coye from January through June, and warmest in north Diablo,. Cove from July throu.gh December, (Figure 4a). Compared to the, control station, temperatures averaged 4.2'C warmer in, south Diablo Cove, and 4.00 C in north Diablo. (ove.

Intertidal temperatures at the Field's Cove stations were 1. lPC warmer than ambient on average..

Subtidal temperatures at -3 m MLLW were generally warmer at the north Diablo Cove stations than south Diablo Cove stations especially in the summer and fall months (Figure 4b). There was 6h6 refueling outage in 2008 fromFebruar'ý 4 to April 12 (2R14) during Which the volume of heated seawater flowing into Diablo Cove from the plant was reduced by apipr6ximately 'half for much of the period. Results for all intertidal and subtidal temperature recording stations are presented in Appendix A and Appiendix B, respectively.

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 5. 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 (+1 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-1 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 m2 permanent quadrats.

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

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 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.

3.0 Intertidal Algae and Invertebrates 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 6r absent, except individuals that were larger than 2.5 cm (1 in) in greatest dimension were counted. In the remaining five quadrats

('count £quadrats'), the same method wasused 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,methodsiused for the algae. All invertebrates, algae, and seagrasses. were identified toithe 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 for each taxon at each transect level for the four surveys completed during the year are presented in Appendix C. The annual. mean abundance for each taxon at each transect level for the entire year across the four.surveys.is also 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, onAly recorded as present. in a quadrat, its abundancewas given, a value of 0.000001 for calculating summnatystatistics.

4.0 Intertidal Fishes 4.0 Interticdal Fishes Intertidal fishes were sampled using the Vertical Band Transect (VBT) sampling method. At each of five stations (Figure 6), three fixed 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 m2 quadrats per station. 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 of fishes of each taxon observed at each station during the four surveys of the year are presented in Appendix D. The tables also list the annual mean abundance and standard deviation for each taxon.

5.0 Subtidal Algae and Invertebrates 5.0 SubtidalAlgae and Invertebrates 5.1 Benthic Algae and Invertebrates Eight, permanent subtidal benthic sampling gtations located in depths ranging from -3 m.,to -6 m

(-10 ft to -20 ft) MLLW were, sampled during, the year (Figure 7). Two control stations were located in Patton Cove, beyond the range of thermal discharges from DCPP, while the remaining six statipns received varying amounts of heat influence fromthe discharge. Stations were circular 22 with.aradius of 3.15 m,,and a sampling area of.2,8.0m. The~center 3.1 m2 of each station, which surrounded a mooring anchor (railcar Wheel), were, not sampled in order to, avoid any unnatural.

algal and invertebrate growth associated, with.4he mooring. Each station was divided into four r.,,

t pa All stations were estabihdpmalyn equal sections, or 'arc quadrants', 7.0 m2 in, area. A blished 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 (brovwn 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)O('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 ihinnumbers too high to aftcurately count in a large area were sampled in the first one-third: area (2.33 in 2) of. eac'chiqldranl. :Tbe count for each of these spec'ies was then multiplied:by three to provide ari 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 ra ius linetwith ten lead markers positioned at decreasing intervals toward the station perimeter was attac~hed.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 us;ed ;A 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 the understory algae :was calculated by dividing the number of 'contacts' by the number of points sampled. All algal spec'ies on the station were identified to the lowest taxonomic level practical.

In the third method, invertebrates were sampled using the subtidal fixed quadrat (SFQ) method in four permanent circular 0.25 in quadrats at each station. The method quantified species composition and abundance of all invertebrate taxa, regardless of size. 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 on horizontal-ESL02009-006.3 PG&E o DCPP-RWMP 2008 Annual Report 0.,..

5.0 Subtidal Algae and Invertebrates 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 cm 2).

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.

5.2 Surface Canopy Kelps The locations and extent of the surface-kelp canopies of Nereocystis luetkeana (bull kelp) and Macrocystis pyrifera (giant kelp) in Diablo Cove within and outside the fixed benthic stations were mapped from direct observations. This task has been done 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 f*%

5.0 Subtidal Algae and Invertebrates 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 8). 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 done on October 28, 2008. Only one bull kelp plant was observed in Diablo Cove during the survey; giant kelp canopies occurred in both north and south Diablo Cove (Figure 8). There are no appendix figures or data tables associated with this task.

6.0 Subtidal Fishes 6.0 Subtidal Fishes Visual counts of fishes were conducted by divers at 12 permanent subtidal stations in four areas located within and outside of Diablo Cove (Figure9). 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 each other in the same area because some were positioned parallel to depth contours, and others were positioned perpendicular to depth contours. 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.

Figure 9. Subtidal fish observation transects.

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 O

6.0 Subtidal Fishes 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 surveydata were the combined species counts of both divers, divided by two. This yielded an average count for each taxon per 50 m by 4 mn benthic transect and per 50 m long by 4 m diameter midwater transect. During each survey, the stations were usually sampled a second time (second replicate) within>two weeks of the initial sampling effort, unless adverse sea conditions precluded a second, ieplicate. Replicate transects were pooled by survey and area. The areas were Field's Cove, north Diablo Cove, south Diablo Cove, and South Control. '

The'survey mean 'and standard deviation for-each taxon within each sampling area for the four survey s completed during the year are presented in Ap'endix H. The survey area means are bas'ed,on the da*ta'ta fom the three transects within each area. The tables also show' -tie overall mean for the entire Year. The survey dates for each area shown in the tables represent the aerag date when the stations and replicates were sampled.
