Chapter 1 INTRODUCTION This report volume presents a summary of regulatory required physical-chemical oceanographic and biological data collected during investigations of the marine environment in the vicinity of the San Onofre Nuclear Generating Station conducted for Southern California Edison Company (SCE). Included is a summary of pertinent data collected in compliance with Environmental Technical Specifica-tions (ETS) for San Onofre Unit I, The National Pollutant Discharge Elimination System-(NPDES) requirements for San Onofre Units 1, 2, and 3, the Preoperational Monitoring Program (PMP) and the Construction Monitoring Program (CMP) for San Onofre Units 2 and 3.
STUDY REQUIREMENTS The ETS is an appendix to the San Onofrt Unit 1 Provisional Operating License and hence a Nuclear Regulatory Comission (NP.C) requirement. Contained
~
within the ETS requirements are both oceanographic and biological study elements oriented to the investigation of San Onofre Unit I operational effects upon the local environment. The oceanographic elements consist of temperature, turbidity,
. heavy metals, dissolved oxygen, and pH, while the biological elements include plankton, fish, intertidal, kelp, and hard benthic communities together with investigations of station impingement and entrainment. Radiological monitoring elements, included with the ETS requirements, are reported to the NRC under a-separate cover.
The PMP, also a ARC environmental requirement, is designed to establish a two-year preoperational data' base for San Onofre Units 2 and 3. The data base will be used to measure the operational effects of San Oncfre Units 2 and 3 on the local marine environment. The PMP study design contains elements similar to the' E" investigation c4 cept generating station entrainment is not addressed.
The CMP requirements are included in the California Regional Water Quality Control Board-San Diego Region. (CRWQCB-SDR) Order 71-6, change T-3. The order requires that a monitoring program be established to determine the effects, on the marine environment, associated with the construction of San Onofre Units 2 and 3. Study elements include sedimentation analysis, intertidal and subtidal infaunal studies, and a kelp investigation.
P The NPDES permits for San Onofre Units 1, 2, and 3 contain essentially the identical operational study elements set forth in the ETS requirements.
Related or complimentary study elements cf the programs outlined above were conducted in concert, where possible, in order to optimize data collection while meeting the individual program. objectives. A schedule of field efforts conducted to meet the requirements outlined above is presented in Table 1-1.
SITE LOCATION The site ~ for the San Onofre Nuclear Generating Station is located on the coast of southern California at approximately 30* 22.5' North latitude and 117*
'32.5' West longitude. San Clemente, the closest city to SONGS, is on the coast approximately 4 km to 'the northwest, while the nearest municipality to the

southeast is Oceanside some 19 km downcoast from the station. The study area extends approximately 6.4 km (4 miles) upcoast,11.5 km (7 miles) downcoast, and 4 km (2 miles) offshore of the generating station site (Figure 1-1).
HISTORICAL BACKGROUND Oceanographic and marine biological studies, referred to as the Marine Environmental Monitoring Program (MEM), began in 1963 in the San Onofre area and were reported on - a se'11 annual basis to CRWQCB-SDR until 1975 (Figure 1-2). In 1975 the Unit 1 ETS program was implemented in compliance with NRC requirements.
The ETS program has continued to the present. In 1976, the CRWQCB issued permits for SONGS Units 1, 2, and 3 under the NPDES which included marine monitoring programs to replace previous MEM requirements. The NPDES marine monitoring requirements (Figure 1-2) have continued to the present.
Studies of the effects of SONGS Units 2 and 3 construction were initiated in 1974 as required by the CRWQCB (Figure 1-2). These studies focused on the impacts 'of sand disposal onto the beach from onshore construction site excava-tions. The studies, called the Sand Disposal Monitoring Program, continued through 1976. The emphasis shifted in 1977 when dredging for the emplacement of the offshore portions of Units 2 'and 3 cooling systems began. Studies focused on the offshore construction activities started in December 1976, as set forth in the CRWQCB order No. 71-6. These studies are referred to as the Construction Monitoring Program (CMP).
In 1978, a Preoperational Monitoring Program was initiated in compliance with requirements of the NRC (Figure 1-2). This Program along with the others mentioned above, will provide a baseline of oceanographic and marine biological

1980 REGULATORY DEVELOPMENTS Preoperational Monitoring Program The PMP investigation which began in mid 1978 terminated in mid 1980 in accordance with NRC authorization following two complete years of baseline data
. collection.
Environmental Technical Specifications Section 4.3 of the Unit 1 ETS requires that a study plan to categorize and detemine effects of plankton entrained within the circulatory water system be submitted for. NRC approval. San Onofre Unit 1 is also subject to a Federal Water Pollution Control Act (FWPCA Section 316(b) demonstration which is admin-istered by the CRWQDB for.the EPA. In order to reduce redundant efforts and regulate duplication between the NRC and EPA, a fomal request to delete the NRC requirement was forwarded to the Commission on 15 November 1979.
A FWPCA 316(b) icnthyoplankton entrainment inventory and loss study was completed. in 1980 which will meet the objective of the ETS plankton entrain-ment study requirement. The ichthyoplankton ' inventory study report will be finalized in 1981 and submitted to the CRWQCB-SDR.
1-5 On 6 February 1980 a formal Change Request (No. 86) was sent to the NRC to delete the receiving water plankton study from the ETS. On 15 October 1980 another Change Request (No. 94) to delete environmental monitoring from the ETS requirements and add a reference to the NPDES permit was sent. Further, a request was prepared for transmittal to the NRC to suspend the ETS program while San Onofre Unit 1 is inoperable.
No response has been received to date on any of these requests.
NPDES / Interim Program In order to maintain continuity with pertinent preoperational study elements (i.e. continuous temperature monitoring, turbidity studies, trawling, and kelp programs), an interim monitoring program was initiated by SCE in mid 1980. The interim program is anticipated to continue until the combined commercial opera-tion of San Onofre Units 2 and 3 is initiated. The CRWQCB-SDR was advised of this action and it is anticipated that a fom of the interim program will be included in the 1981 NPDES permits.
Construction Monitoring Program The CMP investigation was suspended in March 1980 in accordance with the CRWQCB-SDR authorization as construction activity was completed. A study to assess the ef fects of the temporary seawall removal will be initiated upon its removal.
SCOPE AND ORGANIZATION This report volume complies with the April 1 deadline for the presentation of a summary of resul ts from the previous year's activities required by the various regulatory agencies. The regulations allow for the detailed analysis and interpretation of the data collected, to be submitted by July 1 of the reporting year.
The chapters in this report are organized by general study elements (i.e.
Oceanography, Fish, etc.). All regulatory requirements associated with a parti-cular element (i.e. ETS/ NPDES, PMP, and CMP programs) are addressed in the chapter.
San Onofre Unit 1 was offline for a' substantial portion of the year; thus, study elements designed to monitor immediate operating effects of the station, such as changes in temperature and turbidi ty, were. not affected during the of fline period. For the purpose of this summary, only data from the operational period are included for these elements.
Due to their voluminous nature, all raw data collected in 1980 are presented in a separate Comprehensive Data Supplement,. Volume II, which is available from SCE upon request. The Comprehensive Data Supplement contains all regulatory required data as well as data gathered from investigations not contained within the regulatory requirements for the station operation, i.e. Interim Program, and other ancillary data collected to meet program objectives.
A detailed analysis and interpretation of all-ecological data collected for SCE at San Onofre, and infomation from other appropriate sources relating to the program objectives, will be submitted to the regulatory agencies and available for distribution by 1 July 1981 in Volume III of the Annual Operating-Report.
1-6 DESCRIPTION OF THE GENERATING STATION San Onofre Unit 1 is an electrical generating facility utilizing a pressur-ized water nuclear reactor which began commercial operation in 1968. San Onofre Unit 1 is a base-load plant and is nomally operated at full capacity.
Electrical output of Unit 1 is 456 MW.
A once-through cooling system is used to cool the steam cordensers. Seawater is drawn f rom a point 907.4 m (29/7 f t) offshore, located in approximately 8.2 m (27 ft) of water. The of fshore intake structure is fitted with a velocity cap which is designed to reduce the entrapment of marine organisms and draws water horizontally from a depth of 4 to 5 m. After passage through the intake conduit and the condensers, tiie cooling water travels through a discharge conduit which temir.ates in a vertical discharge structure located 750.4 m (2,462 ft) offshore in approximately 7.6 m (25 f t) of water. The discharge results in a surface-oriented themal plume. Under nomal operating conditions, the temperature of the cooling water is raised approximately 19*F across the condensers at a flow rate of 1,325 m3/ min (350,620 gpm).
The Unit I screenwell contains traveling screens and bar racks to remove debris and entrapped marine organisms from the cooling water before it reaches the pumps and steam condensers. Marine fouling growth in the cooling water system is controlled through periodic heat treatments which are typically conducted at intervals of from six to ten weeks. During heat treatments, the temperature of the cooling water in the screenwell is raised to approximately 100'F for 1.75 hr.
At this time, all of the fish within the screenwell which have avoided impinge-ment on the traveling screens during normal operation are succumb to the higher temperature and are removed from the system.
San Onofre Units 2 and 3 are under construction and are scheduled to begin operation in 1981 and 1983, respectively. Each of the new units will have an electrical output of 1110 MW. The once-through cooling system for each unit will have a flow rate of 3,137 m3/ min (830,000 gpm) and a normal operational temperature increase across the condensers of 19.2*F. The intakes will be located 970.2 m (3,183 f t) offshore in 9.8 m (32 ft) of water.
Both units will have diffuser type discharges consisting of 63 ports spread over a distance of 762 m (2,500 f t). The Unit 2 discharge diffuser will extend from 1,786.1 m (5,860 f t) to 2,510.9 m (8,238 f t) offshore and range in depth from 11.9 m (39 ft) to 14.9 m (49 f t). The Unit 3 discharge diffuser will extend from 1,024.4 m (3,361 f t) to 1,889.8 m (6,200 f t) of fshore and range in depth from 9.8 m (32 f t) to 11.6 m (38 ft).
GENERATING STATION OPERATION Unit I The station was offline from 10 April through the end of 1980 due to prob-lems associated with the s generator which required extensive system repair.
The circulating pumps re operation briefly in June and July, and fish impingement studies resum<.
' s this period.
An illustration depicting plant operation including mean daily megawa,t output (station load), inplant AT [(*C) discharge temperature minus intake temperature], and circulating water flov at SONGS Unit I during 1980 are presented in Figure 1-3.

Chapter 2 OCEAN 0 GRAPHY A. TEMPERATURE Monitoring of temperature in the San Onofre receiving waters was conducted bimonthly during 1980 at 46 Unit 1 operational sampling stations in compliance 1
with Environmental Technical Specifications (ETS) Section 3.1.1.a.(5) and NPDES pemits and at 28 additional sampling stations as part of the San Onofre Units 2 and 3 Preoperational Monitoring Program (PMP) (Figures 2A-1 and 2A-2). A data
- ollection record for 1980 is presen+ed in Table 1-1.
The objectives of the temperature studies were to: 1) doc'.sent large spatial and temporal changes in t?mperature throughout the study trea, 2) establish preoperational baseline ct nditions before operation of San Onofre Units 2 and 3, 3) detemine the hori-n ntal and vertical extent of the thermal plume from Unit 1, 4) detemine the atea of influence of Unit 1, 5) estimate the extent to.:hich heated water from Unit 1 is recirculated back into the intake of the circulating water system, and 61 provide temperature data for the analysis and interpretation of biological findings. Temperature monitoring for the Units 2 and 3 PMP, except for contin-hous temperature monitoring, was discontinued on 5 September 1980. Continuous temperature monitoring was conducted throughout 1980.
SAMPLING METHODS A detailed description of instrumentation and methods used for temperature measurements are presented in Brown and Caldwell's procedures manual for ETS and PMP (BC 1979). Detailed methods were also reported in Volume I, Oceanographic Data Report (SCE 1980).
The following presents a synopsis of methods. Vertical profiles of temper-dture were measured wi th a Martek transistor probe and recorded digitally.
Infrared radiometer measurements were taken from an aircraft along predetemined flight paths with a Barnes PRT-5 precision radiometer. Shoreline temperature measurements were taken at 11 shoreline stati ans in conjunction with aerial infrared measurements using a calibrated bucket themometer. Continuous temper-ature data was recorded hourly at the surfaca, mid-depth, and near-bottom of Stations C25 and C22S, and at the surface,15 and 30 f t depths, and near-bottom of Station F2S (Figures 2A-l'and 2A-2). In-plant intake and discharge temperature data were continuously recorded by SCE in-plant personnel at the tsunami wall within the upper 3 ft of the intake and discharge conduits.
RESULTS Results of temperature data collected from January through April 1980 while Unit 1 was in operation for the San Onofre environmental monitoring programs are presented in tabular and graphic _ form by survey in chronological order. Unit I went of fline on 9 April 1980. Results of temperature data collected from May
+hrough December 1980 are presented in the Comprehensive Data Supplement (SCE 1981a). Temperature data presented in this' report for periods when Unit I was in operation include:. vertical temperature profiles required by ETS during bimonthly surveys (Figuies 2A-3 and 2A-4); surface temperatures and times from profile measurements :(Figures 2A-5 and 2A-6); surface temperature isotherms from profile measurements (Figures 2A-7 and 2A-8); surface temperature isotherms from infrared
2A-2 radiometer measurements (Figures 2A-9 and 2A-10); results of shoreline temper-ature measurements (Table 2A-1); graphs of continuous temperature measurements (Figures 2A-11 through 2A-18); and graphs comparing intake, discharge, and ar.: 1ent temperatures (Figures 2A-19 through 2A-22).
An analysis of all temperature data collected during i.10 will be presented in the Volume III, Annual Operating Report (SCE 1981b).
Section 5.6.3b(3)(a) of Appendix B of the ETS for Unit I requires that data losses from continuous monitoring systems (including the continuous temperature recording system) shall not exceed one week continuous or a total in excess of three weeks per year. If data losses exceed these limits, a non-routine report of the occurrence to the Nuclear Regulatory Commission (NRC) is required. Data losses of greater than one week duration occurred at Station C22S mid-depth from 23 January through 4 March 1980, and at Station C22S near-bottom from 4 March through 4 April 1980. These losses were reported to the NRC on 23 July 1980 (NRC Docket No. 50-206).
On 16 May 1980, the NRC formally exempted continuous 'wperature recording from non-routine reporting and required an annual o. ' hore continuous systems temperature retrieval rate of at least 80%. ETS now requires losses resulting in less than 80% return to be described and discussed in the Annual Operating Report. Temperzture data retrieval was more tha.n 80% during 1980.

i l B. TURBIDITY Turbidity was measured in the San Onofre receiving waters bi:nonthly during 1980 at 46 Unit 1 operational sampling stations in compliance with Environmental Technichal Specification (ETS) Section 3.1.1.a.(4) and NPDES permits and at 28 additional sampling stations in the Units 2 and 3 receiving waters in compliance with Preoperational Mc nitoring Program {PMP) reqairements (Fig:res 2A-1 and 2A-2). A data collection record for 1980 is presented in Table 1-L Turbidity study objectives arc to monitor suspended solids in terms of turbidity in the receiving waters near Unit 1 in order to determine any effect of the dis-charge upon water clarity. The objective of preoperational turbudity monitoring is to provide a receiving water baseline for water clarity and turbidity in the vicinity of Units 2 and 3 diffusers. The PMP for oceanographic characteristics was terminated on 5 September 1980. SAMPLING METHODS A detailed description of instrumentation and methods used for turbidity measurements are presented in Brown and Caldwell's procedures manual for ETS and PMP (BC 1979). Detailed methods were also reported in Volume I, Oceanographic Data Report (SCE 1980). The following presents a synopsis of methods. Vertical profiles of percent light transmittance along a 1 m path were measured with a Martek transmissometer and recorded digitally. Observations of the depth of visibility of a 30 cm white Secchi disc were also obtained at each station to document surface water clarity. Aerial photographs of turbidity were taken from an airplane with a 3S mm SLR camera. _qSULTS Results of turbidity data collected for the San Onofre environmental moni-toring program from January through April 1930 when Unit 1 was operational are presented. Unit I was non-operational from 9 April 1980 through the end of the year. Data collected from May through December 1980 are presented in the Comprehensive Data Supplement (SCE 1981a). Results of light transmittance profiles and Secchi disc measurements are presented in Tables 28-1 and 2B-2. Results of turbidity photographs are on file and are available on regest. An analysis of all turbidity data collected during 1980 will be presented in the Volume III. Annual Operating Report (SCE 1981b). LITERATURE CITED Brown and Caldwell. 1979.

C. WATER QUALITY Measurements of surface C0 and pH at San Onofre Unit 1 monitoring Sta-tions CO, X0, and C22S (Figure 2A-2) were required bimonthly during 1980 by l Environmental Technical Specifications (ETS) Sections 3.1.1.a.(3) and 3.1.1.a(7), respectively, and NPLES permi ts. Surface water samples for D0 and pH taken bimonthly during 1980 at ",its 2 and 3 monitoring Stations J25, J2N, J4S, and F225 (Figure 2A-2) fulfilled Preoperational Monitoring Program (PMP) requirements. A data collection record for 1980 is prese7ted in Table 1-1. PMP monitoring for Units 2 and 3 was terminated on 5 September 1980. The objectives of the dissolved oxygen and pH studies were to: 1) assure natural dissolved oxygen and pH levels are maintained. 2) continue to that increase the data base that has been established, 3) indicate the extent to which the operation of Unit 1 af fects dissolved oxygen and pH concentrations in the receiving waters, and 4) provide a preoperational receiving water data base prior to operation of Units 2 and 3, which will subsequently be compared to operational conditions to determine the ef fects of Units 2 and 3 on the receiving waters. The reporting level for dissolved oxygen is a depression of dissolved oxygen concentration of more than 10% from that which occurs naturally, as measured at the control station. The reporting level for pH is values measured outside the range of 7.1 to 8.7 Monitoring of heavy hatal concentrations in the Unit I receiving waters and ocean bottom sediments was conducted quarterly during 1980 in compliance with ETS Section 3.1.La.(2) and NPDES permits. Unit 1 operational monitoring stations included Station X0, C22S, D4N, and D45 (Figure 2A-2). Units 2 and 3 quarterly heavy metals monitoring was conducted at Stations J0, J25, J45, J4N, and J22S (Figure 2A-2) in compliance with the PMP until September 1980 when the program was terminated. The objectives of heavy metals studies were to: 1) detect any measureable increase in heavy metals concentrations in receiving waters or ocean bottom sediments in the viculty of the Unit 1 discharge, and 2) provide a receiving water and ocean bottom sediment predischarge data base for Units 2 and 3 to be used as a reference to aid in subsequent detennination of operational effects of Units 2 and 3 on the concentration of heavy metals in the environment. SAMPLING METHODS Methods for measurement of dissolved oxygen, pH, and heavy metals are in Brown and Caldwell's procedures manual for ETS and presented in detail (BC 1979). Detailed methods were also reported in Volume I, Oceanographic PMP Data Report (SCE 1980). Surface concentrations of dissolved oxygen were measured electronically at Stations CO, X0, and C22S using a Martek dissolved oxygen probe. A modified Winkler titration method was u,ed to calibrate the electronic sensors. Sur-face hydrogen :on concentrations were measured at Stations CO, X0, and C22S using a Martek g,H probe. Mid-depth water and ocean bottom sediment samples for determination of heavy metals were collected by divers and analyzed by atomic absorption to determine the concentrations of chromium, copper, nickel, f ron, and titanium. Sample analyses were conducted in compliance with guidelines established by the U.S. Environmental Protection Agency (USEPA 1969).
. =_ J j i -2 RESULTS Results of surface dissolved oxygen, pH, and heavy metals measurements from bimonthly surveys during 1980 required by ETS and PMP are presented. Additional measurements including dissolved oxygen, pH, sal ini ty, aM density profile da ta, currents, and ocean bottom sediment grain size distr Ibutions, from bimonthly surveys are presented in the Comprehensive Data Supolament (SCE 1981a). Results of surface dissolved oxygen measurements are presented in Table 2C-1. Results of surf ace hydrogen ion concentration (pH) measuremerts are presented in Table 2C-2. Results of receiving waters and ocean botto'9 sediments heavy metals concentration detenninations are presented in Table 20-3. An analysis of all dissolved oxygen, hydrogen ion concentration, and heavy metals data will be included in the Volume III, Annual Operating Report (SCE i 1981b). i Dissolved oxygen concentrations and hydrogen ion concentrations did not exceed specified limits during 1980.

4 Chapter 3 INTERTIDAL The inf aunal intertidal investigation was conducted in compliance with the California Regional Water Quality Control Board - San Diego Region (CRWQCB-SDR) Monitoring and peporting Program No. 71-6 for construction of the San Onofre Nuclear Generating Station Units 2 and 3, including Technical Change Orders 1, 2, and 3. The purpose of the investigation was to determine if construction related changes in the sandy intertidal habitat would have a detrimental effect on the sandy intertidal censnunity. In 1980, the program was conducted in February as construction activities tenninated 6 February 1980. Five pennanent only, intertidal transects, used since December 1976 (MBC 1978) were reoccupied during February 1980 (Figure 3-1). Sampling was conducted on three consecutive days during the lower tidal series of the month. Beach profiling was conducted on the first day. Biological and sedimentological core sampling was performed on the tw days following the surveying. SAMPLING METHODS Biological Sampling Along each transect, seven biological sampling stations were established at one foot vertical increments between mean lower low water (0 ft) and the +6 ft elevation using a modified surveyor's transect. Five replicate 5 liter cores (15.24 cm in diameter and 30 cm long) were collected at each station as it was exposed on a receding tide; one core from the transect centerline, and one at 3 and 6 m to either side. Cores were field screened through a 1.0 mm mesh. Retained organisms were. preserved in 10% buffered Formalin-seawater. All specimens were returned to the laboratory, identified to the lowest possible taxon, and entanera ted. Physical Measurements and Grain Size Detench.ation At each transect a beach profile was constructed from the O ft tidal eleva-tion to the maximum tidal excursion of the survey day, using a self-leveling surveyor's transit. Surf temperatures were recorded at each transect. A core sample for grain size analysis was collected adjacent to each sample. Grain size distribution of the. sediment was detennined by biological standard automatic settling tube analyses (combined with steving for gravel when nectssary). RESULTS Tables 3-1 and 3-2 present a summary of the pertinent biological and physical data collected. For a complete presentation of the biological and physical data collected (SCE 1981a). Ana'ysis of these data will be presented in the Volume 111. Annual Operating Report (SCE 1981b). L

CHAPTER 4 BENTH0S A. ROCK / COBBLE SUBSTRATA, KELP BEDS ENVIRONMENTAL TECHNICAL SPECIFICATIONS (ETS) - UNIT 1 This program was established to assess whether the operation of San Onofre -Nuclear Generating Station Unit I has any significant environmental effect on the dominant, field identifiable nenbers of the epibenthic communities of subtidal cobble habitats and the kelp beds in the vicinity of San Onofre Unit 1. Benthic diving and infrared kelp surveys are conducted in compliance with ETS Section 3.1.2.a(1)C.1, the Construction Monitoring Program (CMP) requirenents, and the National Pollutant Discharge Elinination Systen (NPDES) Pemit requirements. Methods A detailed description of station locations and field methodology is given in ETS Benthic Survey Procedures (LES Procedures EMP 25-5-35). A general review is presented below. Eleven' permanent benthic stations were established in areas of comparable substrata in February 1975, eight (Stations 1-8) along the 10-n depth contour and three (Stations 9-11) in kelp beds (Figure 4A-1). Stations were marked with per-nanent surface buoys. Four stations (Stations 14) were established near the discharge; five stations (Stations 5, 6, 7, 8, 11) were established downcoast, including one in Barn Kelp; one station in San Onofre Kelp (Station 10); and one station in San Mateo Kelp (Station 9). Two additional stations (Stations 22 and
- 23) were located in San Onofre Kelp as part of the Construction Monitoring Program (CMP). A pemanent band transect 10 m in length and 1 m wide was estabitshed at each henthic station.
Field identifiable epibenthic macrobiota were surveyed quarterly at each of the pemi.r.cntly narked benthic stations using nondestructive sampling techniques. Conditions pemitting, narine biologists identified and enumerated epibenthic macrobiota, made estimJtes of percent areal coverage of colonial and encrusting taxa in each of 10 1-n' quadrats at each station, and recorded data on preprinted data sheets. In order to naintain consistency in data recording anong biologists, the type of data to be reported for each organism was standardized and indicated on the data sheets. Additionally. the following infomation was collected within the band tran-sects at Barn Kelp, San Onofre Kelp, and San Mateo Kelp stations: (1) number of stipes on each individual kelp plant counted 2-m above the bottom. -(2) general conditions of the kelp plants (e.g., frayed fronds), and (3) kelp growth (e.g., new fronds). Ancillary data on the configuration and areal extents of the kelp canopies were detemined by aerial infrared and electronic procedures, respectively. Epibenthic nacrobiota were surveyed quarterly from 24 January - 10 February, 28 April -- 2 June, 24 July - 17 August, and 23 October. - 3 November. Nearshore winter stoms during January, February, and March resulted in unacceptable diving 8.--- ..y p p, q.P

4A-3 conditions; consequently only six ETS benthic stations were sampled during the first quarterly sampling period of 1980. This data loss was reported to the Nuclear Regulatory Commission (NRC) by means of a 30-day non-routine report sub-nitted in March 1980 in accordance with Administrative Control Section 5 of the ETS. Adverse weather conditions prevented Construction Monitoring Stations 22 and 23 from being effectively sampled during the first quarterly survey period. Sanpling at these stations was conducted during the April-June survey. The configurations of the kelp canopies of the San Mateo, San Onofre, and Barn Kelp Beds were monitored quarterly by aerial infrared photography. The areal extents of the kelp canopies were mapped twice a year by electronic proce-dures (SCE 1980e). Results A summary of data collected during 1980 ETS and CMP benthic surveys is pre-sented in the following tables. Rank, mean abundance, and frequency of occurrence of percent cover and enumerated taxa sampled at all stations during each survey are presented in tabular form. The detailed distribution and abundance of orga-nisms sampled at each station are contained in Volume II: Comprehensive Annual Data Report (SCE 1981a) and will be analyzed in Volume III: Data Analysis for the 1980 Annual Operating Report (SCE 1981b). Results of the quarterly monitoring of the San Mateo, San Onofre, and Barn Kelp canopies by aerial inf rared photography, and the semiannual kelp mapping surveys are on file. PRE 0PERATIONAL MONITORING PROGRAM (PMP) - UNITS 2 AND 3 Preoperational benthic surveys were conducted quarterly in compliance with specifications set forth by the Nuclear Regulatory Commission on 6 July 1978, for San Onofre Units 2 and 3. The objective of this study was to provide baseline data for use in deter-nining the _ nature, extent, and significance of the effects of Units 2 and 3 on 'the species composition, distribution, and abundance of the epibenthic biota associated with the cobble / sand' habitat. Methods A detailed description of station locations and field methodology is given in PMP Benthic Survey Procedures (LES Procedures B-1-1/79). A general. review is presented below. Ten permanent - benthic stations were established along the 15-m isobath in areas _of comparable substrata in June and July of 1978 (Figure 4A-1). Stations were established in pairs and marked with permanent surface buoys. Two stations ara located in Zone 3A (Stations 12,13), OB (Stations 14,15), and 6 (Stations 20, 21), and four stations (Stations 16-19) are located in Zone 28. Each per-2 nanent benthic station consists of a rectangular 6.0-m area (2 m x 3 m). 3 Diving marine biologists utilized two reference (stationary) lines and one 2 station area with 300 evenly distri - novable sampling line to sample each 6.0-m huted points. Data collected - at _ each point included the identification of substratun and biological taxa. Up to three taxa levels,2 indicating layering in the community, were recorded. Adgitionally, four 0.125-n square quadrats were randomly located within the 6.0-m station' area and were sampled with 60 evenly distributed points.to identify small cryptic, clunped, or patchily distributed
4A-4 2 taxa. Data for both sanoling elements (6.0-n and 0.125-n2 quadrats) were recorded by individual biologists on task-specific, waterproof data sheets. The FMP benthic study was completed in June 1980 in conpliance with the objectives of the PMP as approved by the hPC. Althoegh the PWP benthic sampling j periods were scheduled quarterly, only the second quarterly survey was conpleted during 1980. Only two PMP benthic stations were sanoled during the first 1980 [ sampling ef fort before it was terminated due to unacceptable diving conditions resulting fron nearshore s to rns. This data loss was reported to the Nuclear Regulatory Comission (NRC) by neans of a 30-day non-routine report submitted in March 1980 in accordance with Adninistrative Control Section 5 o' the ETS. The second quarterly sangling was coapleted during the period fron 7way - 2 June 1980. Results A sumary of data collected during the 19*0 PMP benthic surveys is presented in following tables., Rank, the nean abundance, and frequency of occurrence of taxa sa pied by the 6.0-n' and 0.125-n2 technicues at all stations during each I survey are presented in tabular form. The detailed distribution and abundance of organisns sanpled at each station are contained in Volume II: Comprehensi ' Annual Data Report (SCE 1981a) and will be analyzed in Volone III: Data Analysis for the Annual Operating Report (SCE 1981b).

4B. BENTHIC INFAUNAL STUDY The benthic infaunal investigation was conducted in compliance with the California 9egional Water Quality Control Board - San Diego Region (CRWQCB-SDR) Monitoring and Reporting Program No. 71-6 for Construction of the San Onofre Nuclear Generating Station Units 2 and 3, including Technical Change Orders 1, 2, and 3. The purpose of the investigation was to investigate effects of dredge induced sedimentation on the inf aunal invertebrate comunity adjacent to San Onofre. In 1980 the program was conducted in March only (Table 1-1) as construc-tion activities terminated 6 February 1980. Biological collections were made along six permanent transects used since December 1976 (MBC 1978). Biological collections were made at stations located on the 6, 9, and 15 m isobaths of six offshore transects. Two of the six transects were established as reference areas, one upcoast and one downcoast of the constuction area. The remaining four treat-merit transects flank the axis along which dredging and conduit emplacement emceeded (Fig. 4B-1). SAMPLING METHODS Biological Sampling At each station, biological samples were collected for the identification and entsneration of taxa present. At stations located along the 6 m isobath (A1, . B1,' C1, D1, Ei, and F1) five one liter (10 cm x 10 cm x 10 cm) replicate box core samples were collected by divers. Collections from the 9 and 15 m isobath stations ( A2, B2, C2, 02, E2, F2, A3, B3, C3, 03, E3, and F3) consisted of 12 replicate one liter samples. Each sample was screened through a 0.5 mm screen in the fiel/ and the retained fraction preserved in 10% Formalin-seawater. Physical Measurement and Sediment Characteristic Determination At each station, sediment stake heights (vertical distance from substrate to top of a permanent monument), which are used to ' detect changes in bottom height between surveys, were determined with a tape measure. Sediment deposition rates were calculated from sediment trap collections. At each station, sediment traps were positioned on 'Op of the pennanent monuments. The traps were replaced monthly. The contents were returned to the laboratory, oven dried at 100*C for 24 hrs, and their dry weight recorded. Sediment samples for total organic carbon determinations and grain size analysis were collected at each station adjacent to the biological samples. At stations located along the 6 m isobath, three core samples each were collected for both sediment size and organic carbon analyses. At stations located along the 9'and 15 m isobaths, four core samples were collected for sediment size analysis and eight samples collected for organic carbon analyses. Total organic carbon content was determined for each sample using a LEC0 gasometric carbon analyzer. Grain size was determined by automatic settling tube analyses of sand sized fractions (combined with sieving for gravel when necessary). Silt-clay fractions were analyzed using stanard hydrometric techniques. Calculations for mean phi, skewness, kurtosis, and other sediment descriptive characteristics followed the formula of Inman (1952).

CHAPTER 5 PLANKTON - RECEIVING WATERS This single program meets the requirements of the Environmental Technical Specifications (ETS), the Preoperational Menitoring Program (PMP), and the National Pollutant Discharge Elimination System (NPDES). This program was designed to determine the nature, extent, and significance of the effects of San Onofre Units 1, 2, and 3 operations on the species composition, distribution, and abundance of plankton offshore San Onofre. METHODS A detailed description of station locations and field and laboratory methodo-logy is given in combined ETS and PMP procedures (LES Procedures P-0-8/78). A general review is presented below. E' eld Eleven stations comprise the required plankton sampling station array for the combined Unit 1 ETS and Units 2 and 3 PMP programs (Figure 5-1). The ETS stations (Stations 1-7) are located upcoast, downcoast, and directly offshore of SONGS along the 10-m isobath. The required PMP stations (Stations 10-13) are similarly located on the 15-m isobath (Figure 5-1). Biological sampling included collection of zooplankton samples and whole- -water samples for analysis of chlorophyll a,and phaeopigment concentration. These t3mples were collected' concurrently from two strata within the water colum t it each station by use of a plankton pump system. The upper stratum extends from che surface to 5-m depth at the ETS stations and from the surface to 8-m depth at the PMP stations. The lower stratuni encompasses the depth interval from 5 to 10 m at the ETS stations and from 8 m to the bottom for the PMP stations. Within each of 3 .these strata, samples were integrated by obtaining 0.33 m of water at each 1-m depth interval within a stratum. Zooplankton were obtained by filtering water through a 202-un mesh' plankton net. A 450-nl whole-water sample was obtained for chlorophyll a and phaeopigment concentration analysis by collecting a small frac-tion of the water pumped through the plankton net. Two replicate water samples and two replicate zooplankton samples were collected from each stratum at each station. The first replicate was taken as the pump intake was lowered and the second as it was raised. This procedure was repeated on three days within a seven-day period for each survey during - January, March, and May except that inshore Stations 2, 3, and 5 were not sampled on the second and -third days. All samples were collected during daylight hours. Physical data were collected concurrently with biological sampling. Tempera-ture and transimissivity measurements were taken at 1-m intervals using a Martek XMS tenperature-transmissivity unit. During 1980, transmissivity-depth profiles were obtained at selected. stations during = the January, March, and May surveys only. Temperature-depth profiles were obtained each time a station was sampled. Gross current speed and direction of flow was estimated by deployment of a sub-surface drogue for. a -measured length of. time (15 min to I h) while each station was occupied. Meteorological information, including cloud cover, wind, and sea conditions were ~ obtained each time a station was occupied. These data are pre-sented in Volume II: Comprehensive' Annual Data Report (SCE 1981a) and will, where +. t

5-3 appropriate, be analyzed with the biological data in Volume III: Data Analysis '3 for the 1980 Annual Operating Report (SCE 1981b). Plankton surveys were conducted on 8, 10, and 13 January; 10-12 March. 15, 17, and 18 May; 19 July; 16 September; and 5 November 1980. During the January, March, and May surveys all 11 required stations were sampled in accordance with combined ETS, NPDES, and PMP requirements. The two-year PMP was completed in May 1980, therefore, surveys during July September, and November wera conducted only at Stations 1-7 in accordance with the ETS. Laboratory Phytoplankton populations were assessed by determining phytopigment concen-trations from whole-water samples. These samples were glass-fiber filtered, ground in acetone, and exanined with a Turner fluorometer for the determination of chlorophyll a_ and phaeopigment concentrations. Assessment of zooplankton populations was conducted on the basis of iden-tification and enumeratiot. of select zooplankton taxa ard determination of total dry weight biomass. Using properly selected zooplankton species, the time and expense of sample processing can be reduced without an accompanying loss of information. Each of the select taxa examined was numerically abundant based on three years of ETS data and is considered a major component of the taxonomic and trophic structure of the zooplankton community offshore of San Onofre. These select taxa consist of Penilia avirostris, Acartia tonsa, Acartia spp. copepo-dites, Corycaeus anglicus, Euterpina acutifrons, Labidocera trispinosa copepo-dites, Oithona oculata, Paracalanus parvus, pracalanus parvus copepodites, Clausocalanus spp., all other copepods as an aggregate, cypris larvae, cypho- -nautes larvae, Sagitta spp., and all other plankton taxa as an aggregate. If an additional taxon was found to comprise more than 30% of the samples during r. survey, it was alsa enumerated. Generally, zooplankton samples were sufficiently dense that sampic abundances were estimated from subsamples. Stempel pipettes were used to sotain measured subsamples, or, if-abundances were very low, a Folsom plankton splitter was used, or an entire sample was enumerated. Zooplankton bionass was measured for each zooplankton sample collected during the January. March, and May surveys. Biomass samples were filtered and dried at 60*C for 24 h prior to weighing. RESULTS Data collected during the 1980 plankton surveys are presented .n the following data tables. Mean zooplankton abundance data sampled at the ETs and PMP stations are presented for each survey. Ancillary data co lected but nc'. required -are presented in Volume 11: Comprehensive Annual Data Report (SCE 19-la). These data, where appropriate, will be analyzed in detail in Volume III: Data Analysis for the 1980 Annual Operating Report (SCE 1981b).

CHAPTER 6 FISH A. FISH IN THF RECEIVING WATERS - GILL NETS This single progran meets the requirements of both the Environcental
- Technical. Specifications (ETS) and Preoperational Mcaitoring Program (PMP). This program was designed to determine the nature, extent, and significance of the effects of San Onofre Unit 1 operations and to provide baseline infornation for San Onofre Units 2 and 3 on the species composition, distribution, and abundance of adult fish offshore San Onofre in conjunction with an additional program based on samples collected by otter trawl.
AETHODS A detailed description of station locations and field methodology is given in ETS Fish Survey Procedures ('.ES Procedures EPP 25-5-35) and PMP Fish Survey Procedures (LES Procedures N-1-1/79). A general review of these procedures is given below. Field ' A total of 14 (6 ETS and 8 PMP) gill net stations were established at sites in an upcoast (San Mateo Point) reference area; an area directly offshore of San Onofre Units ~ 1, 2, and 3; and a downcoast (Don Light) reference area (Figure 6A-1). Each gill net station consisted 'of a pair of identical Marinovich experi-nental monofilament gill nets for replicate sampling. Each net measured 45.7 m .long, 1.8 m deep, and contained six 7.6-m oanels of bar nesh of the following sizes: 19 m, 25 m, 32 m, 38 m, 44 m, and 64 m. All nets were set over nostly cobble substrata, perpendicular to the shoreline and were retrieved after 24 h. This. fishing period encompassed both dusk and dawn, the ' periods of greatest fish activity. Eight of the 14 stations (Stations 1, 2, 3, 6, 7, 8, 11, and 12) were located on the 9.1-m (30-f t) isobath. The remaining six stations (Stations 4, 5, 9, 10, 13, and 14) were located on the 13.7-m (45-f t) isobath (Figure 6A-1). Station 3 was located within 50 m of the San Onofre Unit-1 discharge and Station 6 was located approximately 2 km downcoast of Stations 7 and 8. Stations 1-through 6 were ETS stations; the remaining stations were PMP stations. Temperature-transnissivity profile data were collected at' each cluster of ~ ' 9.1-r, and 13. 7-m - gill net stations once daily for the two days of the survey. ' Data were taken ' at 1+m depth intervals from the surface to the bottom and are presented in Volume 11: Comprehensive Annual Data Report (SCE 1981a). Both ETS and PMP gill net sampling was conducted bimonthly on 26-27 February, 23-24 April, and 25-26 June 1980.. in June the two-year PMP ended and the ETS continued 4uring the remainder of 1980. The remaining 1980 ETS sampling was con-ducted quarterly on'21-22 August and 10-11 December 1980. Laboratory All fishes collected 'in gill ' net samples were identified, counted, and visually inspected for anomal.ies, diseases, and-parasites. A group of select' fish

6A-3 species has been studied more intensively with the onset of the combined program. These following species were selected because of their numerical dominance in San Onofre Unit 1 impingement samples, their abundance offshore, and/or because of their value to local sport and commercial fisheries. Queenfish Seriphus politus Genyonemus lineatus White croaker Spotfin croaker Roncador stearnsii Cynoscion nobilis White seabass Hyperprosopon argenteum Walleye surfperch Phanerodon furcatus White surfperch Paralabra,x clathratus Kelp bass Barred sand bass Paralabrax nebulifer 4 Paralabrax maculatofasciatus Spotted sand bass Paralichthys californicus California halibut Select species were identified, enumerated, measured, and sexed. Standard lengths (tip of the snout to the end of the vertebral column) of a maximum of 125 indivi-duals per species from each gill net sample were measured. A subset of no more than 50 individuals per species were sexed (male, female, indeterminate) by exa-mining their gonads or by noting secondary sexual characteristics when evident. Indeterminate fish were sexually immature, recently spawned, or damaged such that sex cannot be determined. General reproductive condition of itsh was also noted. A maximun of 10 female Seriphus politus and 10 female Genyonemus lineatus per net w 'e subsampled for gonosomatic index analysis except during the December survey. o;nad and total body wet weights were determined for each subsampled female with gonad weight divided by total body weight to determine the index on a survey, area, and depth basis. In addition to the preceding methods, which were utilized for the combined Units 1, 2, and 3 program, certain additional length and sex data were taken to maintain compliance with the Unit 1 ETS at some stations. The ETS required that all fish from the six nets near the Unit 1 discharge (Zone OA) and the six nets at the downcoast inshore reference area (Zone 6) be measured and that a maximum of 10 individuals of resident species be subsampled for sex composition. RESULTS Summary community composition and total abundance data tables for all species. combined and for four select species. (Seriphus politus, Genyonemus lineatus, Hyperprosopon argenteum, and Phanerodon furcatus) collected during 1980 are presented. Length-frequency histograms including the ratio of males: females of the two most frequently collected. species, S. politus and G. lineatus, are pre-sented as annual totals based on area and depth. A prese7tation of abundance, species composition, sex composition, gonosoma- + tic indices (GSI), length-frequency, parasitized and ancmalous species, and-temperature-transmissivity. profile data, and ~ field notes collected for the ETS and PMP are presented in Volume II: Comprehensive Annual Data Report (SCE 1981a).

6B. FISH IMPINGEMENT The impingement study was conducted in compliance with Environmental Tech-nical Specification (ETS) Section 3.1.2.a(2) Heat Treatment, and ETS Section 4.2 Normal Operation, to provide data on the fish impinged by SONGS Unit 1. METHODS A detailed descriptin of impingement sampling methods is given in ETS procedures for both nomal operation (SCE R&D Procedures EMP 25-5-25) and heat treatments (SCE R&D Procedures EMP 25-5-58). A general review is presented below. Nomal Operation Samples are collected at least weekly during normal flow operations. These samples are based upon a period of 24 hrs of continuous operations. Abundance data collected on an operational period of less than 24 hrs will be standardized to a 24 hr operational period. Due to irregular flow scheduling resultir.g from station shutdown, fish samples in 1980 could on.ly be taken during the months of January, February, March, April, June, and July. The data collected consists of the total nanber of taxa, number of indi-viduals per taxon, and the aggregate weight per taxon of fish impinged en the traveling screens and bar rakes during the sampling period. Standard length for a maximum of 125 individuals per select species and sex for a maximum of 50 individuals per select specier re also detemined. Heat Treatment During each heat treatment, fish collected by traveling screens and bar rakes were identified, enumerated, weighed, and measured. Data collected is the same as described for nomal operation sampling. RESULTS Fish impingement data collected during 1979 were obtained from two heat treatment, and 32 normal operation samples. A sunmary of the data collected are presented in the following tables. The number of individuals and aggregate weight per taxon are sunmarized for nomal operation and heat treatment collections. A more detailed breakdown of the data by individual sample is presented in the Comprehensive Data Supplement (SCE 1981). In addition, a detailed sumary of length and sex data of impinged fish as well as abiotic parameters measured at the time of sampling are presented in the Supplement.
