1.0 Introduction 1.0 Introduction Monitoring of the marine environment near the Diablo Canyon Power Plant (DCPP) is required by National Pollutant Discharge Elimination System (NPDES) Permit Order No. 90-09, 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 water temperature and biological data collected from January 2006 through December 2006 from the program's intertidal and subtidal monitoring tasks (Table 1). The report sections are divided according to the program's individual study tasks. Sampling methods for the intertidal and subtidal studies are followed by the results for the surveys. This report is mainly a data presentation, and does not include any analysis or discussion of results. Most results are presented in the accompanying appendices. Comprehensive analyses of changes in the marine environment resulting from the DCPP discharge have been presented in Tenera (1988, 1997, 1999a, 1999b and 2002; see Section 7.0 -Literature Cited).

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 mean lower low water (MLLW) elevation (Figure 2). Subtidal temperature recorders were located at depths from -3 to -6 m MLLW (Figure 3). The naming designation of individual subtidal stations reflects the area location and number, followed by the station depth relative to MLLW (e.g., NDC 1 -3m is North Diablo Cove subtidal Station 1 at a depth of -3 m MLLW).

The following 13 stations were nearest to the point of discharge 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 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-lV.

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 0.0 10C with an accuracy of+/- 0.2'C. Temperature units were deployed at a station for approximately 60 days and then exchanged with a serviced, calibrated unit. Intertidal temperature units recorded air temperatures when tidal levels receded below about

+0.6 m MLLW. Air temperatures recorded by the intertidal temperature units were identified and removed from the database by referencing tidal height measurements that were calculated as the average tidal height from local NOAA tide stations at Morro Bay to the north and Port San Luis to the south.

Results for all subtidal and intertidal temperature recording stations are presented in Appendix A and Appendix 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 4. 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-l 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 barren cobble. Therefore, the upper transect at that station was located lower in 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 m2 fixed quadrats. The quadrats were mainly on bedrock and boulders, but various amounts of cobble and sand 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 estimate the percent cover of the understory species and bare substrates. Species that were less than one percent cover in abundance 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 in the same quadrats as the algae. In five of the ten quadrats, all species were recorded as either present or absent, and individuals larger than 2.5 cm in greatest dimension 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 within the ten quadrats along each transect and within an additional five quadrats on the transect. The additional five quadrats had been sampled for algae and invertebrates during historical surveys in the 1980s, but have been retained only to provide additional quadrats sampled for intertidal abalone.

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

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 5), 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 m 2 permanent sampling quadrats, for a total of thirty-six 1 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. Newly settled juvenile fishes were not identified to the species level but were grouped into composite taxa (e.g.,

Pholid/Stichaeid, Anoplarchus/Cebidichthys).

The total numbers of fishes of each taxon observed at each station during each of 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.

5.1 Benthic Algae and Invertebrates 1

Eight permanent subtidal benthic sampling stations located in depths ranging from -3 m to -6 m n

(-10 ft to -20 ft) MLLW were sampled over the year (Figure 6). 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 heat influence from the discharge. Stations were circular I

with a radius of 3.15 m and a sampling area of 28.0 inm. The center 3.1 m2 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 I

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 I

(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 (length or width). Juvenile kelp plants that could not be identified to the I

species level were counted and recorded as 'Laminariales.' A few common species that generally occurred in numbers too high to accurately count in a large area were sampled over time in the same one-third area (2.33 M2 ) of each quadrant. The count for each of these species was then I

multiplied by three to provide an abundance estimate for the entire quadrant.

In the second sampling method, all understory algal species were quantified at the stations as percent cover using the subtidal line-point contact (SLC) sampling method. A radius line with ten points 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 points within each quadrant (total of 200 points per station) were randomly selected before sampling using a random number table. For each survey the same set of random points was used at all stations.

Random sampling loci were changed for subsequent surveys. The presence of all algal species, I

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 I

of points sampled. Species were identified to the lowest taxonomic level practical.

In the third method, invertebrates were sampled using the subtidal fixed quadrat (SFQ) method n

in four permanent circular 0.25 M2 quadrats within each station. The method quantified species composition and the abundance of all invertebrate taxa regardless of size. A fixed quadrat was located within each of the four SAQ quadrants, generally on bedrock or boulder substrate.

I Depending upon the degree of topographical relief, two quadrats were located on horizontal-aspect substrate and two quadrats were located on vertical-aspect substrate. All non-encrusting taxa were identified and counted. The coverage of encrusting taxa (e.g., colonial/social tunicates)

I was quantified in square centimeter units if the total equaled or exceeded 6.5 cm 2 (1 square inch).

Otherwise, the encrusting taxon was recorded as 'present'.

5.0 Subtidal Algae and Invertebrates 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 show annual mean taxa abundances by station based on the average of all surveys sampled over the year. Algal taxa in the RPC 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 Macrocystispyrifera (giant kelp) in Diablo Cove within and outside the fixed benthic stations were mapped from direct observations (Figures 6 and 7). 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) were used to count and map the distribution of individual bull kelp plants and to map the spatial extent of giant kelp canopies (Figure 7). Bull kelp plants with bare bulbs, indicating early senescence in plants, are noted in this task when possible.

The annual habitat-forming kelp survey was done on October 4, 2006. No bull kelp plants were observed in Diablo Cove during the survey. The distribution of giant kelp surface canopies in

6.0 Subtidal Fishes 6.0 Subtidal Fishes Visual counts of fishes were conducted by divers at 12 fixed subtidal stations located within and outside of the thermal discharge area (Figure 8). 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. A station was sampled by first deploying a fiberglass measuring tape to function as 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.

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.

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

During each survey, the stations were usually sampled a second time (second replicate) within approximately one to two weeks of the initial sampling effort, unless adverse sea conditions precluded a second replicate. 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 each of the four surveys completed during the year are presented in Appendix H. The survey area means are based on the data from the three transects within each area. The tables also show the overall mean for the entire year. The survey dates for each area shown in the tables represent the average date when the stations and replicates were sampled. The second replicate set of stations for the fourth (last) survey of the year could not be completed due to prolonged high swell conditions.

Therefore, the data for the fourth survey of the year was from the initial replicate set of stations sampled in each area.
