 12.4 m (

40.7 ft) MLLW, and a second unit (CM2) approximately 3.2 km (2.0 mi) from shore off the San Gabriel River mouth at a depth of

- 16.2 m (

 53.1 ft) MLLW (Figure 3.3

- 2). Both stations were commissioned on January 10, 2006. Station CM2 was decommissioned on January 8, 2007 and Station CM1 was decommissioned on January 11, 2007. Data were downloaded on May 2, 2006 and August 31, 2006. From May 2

 5, 2006 Station CM1 did not collect current data due to operational error after the data download. The unit at CM1 had an operating frequency of 1 MHz, while the unit at CM2 had an operating frequency of 600 kHz (Table A1

- 1). Both units collected data at hourly intervals in a usable range that extended from 0.5 m (1 .6 ft) from the ADCP to somewhat less than 90% of the distance to the surface. The half

- power full beam

- width was 2.4 degrees for both units. Water temperature and water depth (pressure) were also measured concurrently by the units. Water temperatures were calibrated over an approximately four

- month period from September 2006 to January 2007 using two calibrated Starr

- Oddi thermistors. Pressure measurements were adjusted using barometric pressure data measured at the Los Angeles International Airport and
co rrected for sea level.

### Haynes Generating Station

IM&E Report Appendix B1: Entrainment Field Sampling Procedure

B1 - 2 APPENDIX B1: PROCEDURE FOR COLLE CTING PLANKTON SAMPLES FOR ENTRAINMENT STUDIES 1.0 PURPOSE The purpose of this document is to define the steps and equipment necessary to accurately collect plankton samples using a wheeled bongo frame near the Haynes Generating Station (HnGS). 

### 2.0 RESPONS IBILITIES
2.1 Task/Field leader:

 Notify the station of the proposed sampling dates.

 Schedule and coordinate sampling surveys and notifying the U.S. Coast Guard prior to sampling.

 Verify that all investigating biologists conducting the sampling have read and understand these procedures.

 Verify that procedures have been followed during sample collection and that the sampling has been conducted safely.

 Verify that information on data sheets have been reviewed and properly recorded. 2.2 Investigating biologis t:

 Conduct sampling using the following procedures.

### 4.0 PROCEDURES
4.1 Mobilization

a. Notify plant personnel of the dates of field sampling prior to the sampling day. b. Ensure there are enough jars, labels, and preservative (formalin) for the sample collection. Print the required number of blank field data sheets on waterproof paper.

c. Inspect the wheeled bongo frame, nets and codends for any damage. If damaged, repairs must be made before sampling begins. Ensure that the flowmeters have been calibrated within the past 90 days and that th ey are operational. Attach a flowmeter in approximately the center of each frame mouth. d. Ensure that all additional equipment (Table B1

- 1) is in good operating condition. Make repairs if necessary.

### Haynes Generating Station

IM&E Report Appendix B1: Entrainment Field Sampling Procedure

B1 - 3 4.2 Sample Collection

a. Samples will be collected every six hours in a 24

- hr period (four cycles) according to the schedule developed by the Task Leader. A survey team consists of at least a boat driver and two investigating biologists to conduct the sampling. b. Locate the station using the latitude/longitude coordinates. Determine the water depth with the fathometer and record the water depth on the field data sheet.

c. Ensure that the winch line and a weight (15

- 20 lb salmon ball) are securely attached to the center of the bongo frame. Ensure that the nets, codends and flow meters are securely attached. The nets should be 333

b er o n t h e f i e l d d at a sh e e t ( Att a chm ent B 1

- 1). Record the number from the flowmeter counter spins on the field data sheet prior to lowering the frame into the w ater. Record the start time (local time) on the field data sheet.

e. Using the measured marks on the winch cable, lower the frame and nets through the water column until the wheels on the sides of the frame are on the bottom. When the cable starts to slack, t he boat is motored forward and the cable is retrieved trying to maintain a 45

- degree tow angle. When the frame reaches the surface, carefully pull it into the boat. Verify that the nets have not picked up any sediment from the bottom. If there is any sedim ent in the nets or codends, discard both samples by detaching the codends and rinsing the nets of collected material and then reattach the codends. Repeat the sample collection at that station. f. Check that the number of spins on each flowmeter counter to ve rify that the target volume of 15

- 20 m3 has been collected (number of spins should be about 2,000). If the target volume has not been met with one tow, subsequent tows will be performed at the station until the target volume has been collected. g. If the correct volume has been collected record the end number of spins from each flowmeter on the field data sheet. Subtract the initial number of spins from the end number and record the total on the field data sheet. If the integrity of either or both flowmeter r eadings is questionable (e.g., seaweed wrapped around the propellers), discard both samples by detaching the codends and rinsing the nets of collected material and then reattach the codends. Repeat the sample collection at that station. h. Record the end time (local time) on the field data sheet. i. Beginning at the top of the net, rinse the collected material down into the codend. Since the wash water is not filtered and may contain plankton, rinse the net from the outside ensuring that unfiltered water does not contaminate the sample. Inspect the net to ensure that it has been thoroughly rinsed. Samples will then be carefully transferred to prelabeled jars with preprinted internal labels. The sample from each net will be placed in separate labeled jars. j. Detach the codend from net #1 and rinse the sample from the codend into a labeled sample jar using a squirt bottle containing seawater. Then, using a graduated cylinder or other measuring device, add enough formalin to make a 10%

n. Deliver the samples to the laboratory at the completion of the sampling effort. 4.3 Sample Voiding in the Field

a. Samples should be voided if any of the following occurs: 1) possible flowmeter obstruction due to kelp or other debris on the propeller, 2) obviously malfunctioning or damaged flowmeters; 3) damaged (torn) nets found after a sample is collected; 4) large quantities of sediment in the net that were collected when the wheeled bongo frame was on the bottom; 5) g ear failure which prevents completion of any tows/hauls; 6) an incident or situation which may prevent reliable data collection; 7) an incident or situation which may jeopardize the safety of sampling personnel. b. If a hole or tear is found in the net mesh, mark the damaged area and either repair or replace the net. Discard both samples and repeat the sample collection. Record this on the data sheet.

c. The number of flowmeter spins from the paired bongo nets needs to be checked in the field to confirm that the measured volumes were similar.

B2 - 1 APPENDIX B2: PROCEDURE FOR SORTING PLANKTON SAM PLES IN THE LABORATORY 1.0 PURPOSE The purpose of this procedure is to define the steps for sorting target organisms from plankton samples collected at Haynes Generating Station, and to describe the Quality Control Program (QC) used to monitor the sorting accuracy of individual sorters. 

### 2.0 RESPONSIBILITIES

 Laboratory Supervisor is responsible for assuring that plankton sample sorting is in accordance with written procedures.

 The Quality Control Supervisor is responsible for implementing the Quality Control Program, which monitors sorting accuracy in accordance with written procedures.

 Investigating biologists are responsible for sorting samples in accordance with written procedures. 

### 3.0 INSTRUCTIONS
3.1 Sorting Procedures 3.1.1 Sample Processing

a. Ensure that the proper equipment necessary for sample processing is available (Table B2

- 1). b. Samples that were originally fixed in formaldehyde after collection must be transferred to 70% ethanol before laboratory processing. This is done outside to lessen the exposu re to formaldehyde fumes. Only qualified personnel who have read and signed the information about the hazards of working with formaldehyde may transfer samples. 1. A funnel with the appropriate mesh size attached to its bottom opening is placed into a jar or can. The mesh must not be larger than that used during sample collection. Place the jar and funnel in a tray so the sample can be retrieved if spillage occurs. 2. Pour the sample carefully into the canning funnel. The sample jar and jar lid are rinsed with water, directing the water and organisms into the funnel. Rinse the sample with water to flush the formaldehyde from the sample. 3. Rinse the sample into a labeled jar with 70% ethanol from a squeeze bottle. Make certain that the jar has both an inner label an d a jar top label. Additional ethanol is added to the sample jar to cover the sample. 4. The waste formaldehyde and rinse water is then discarded into the appropriate hazardous waste container.

c. Consult the sorting schedule posted in the processing laboratory to determine sorting priorities. d. Sign out the sample in the Laboratory Tracking MS Excel file and the Laboratory Sample Tracking Sheet (Attachment B2

- 1 ) b y wri ti n g yo ur i ni ti al s un d er th e ‘ s o r t er ’ c o l umn
. Transcribe information from the sample label into t h e S o r t er ’ s L o g B o o k ( Att a chm ent B 2

Adjust the magnification so that the field of view is slightly larger than the width of an individual marked grid. k. Arrange the light source to provide adequate illumination. l. Carefully scan the entire sorting tray using the grids for ori entation. Remove the target organism with forceps and place them either into a shell vial containing 70% ethanol or into a small dish containing water. Count the organisms as they are removed. A list of what target organisms and when to pull them is posted in the lab.

m. Log the number of organisms removed from the sample in the sorter notebook.

n. Scan the tray a second time. If target organisms are found on the second pass, repeat a third time. Continue this process until a scan does not produce any additional target organisms.

The sample should be stirred up in order to get a fair amount of sample in the aliquot. Once the aliquot is processed for fish eggs it may be returned to the original sample jar with the rest of the sorted sample. Make sure it is noted in the logbook and record the total volume of the sample and the volume of the sub sample. There will be an extra data sheet in the laboratory tracking sheets and a column in the MS Excel tracking sheets to record the sub sample information. On top of the sample jar put a white dot with survey number, sample number, sorters initials, sub s amp l e d at e , an d “ S S ”

B3 - 2 3.2 Identification Quality Control (QC) Program 3.1.2 Fishes

a. The first ten samples of larval fishes that are identified by an individual identifying biologist will be completely re

- identified by a designated identification QC biologist. A total of at least 50 individuals from at least 5 taxa (50/5 criteria) must be present in these first te n samples. If the first 10 consecutive samples do not pass the 50/5 criteria, additional samples must be re

identified until this criteria is met. b. The identifying biologist must maintain a 95% identification accuracy level in these first 10 samples. For all samples, if a sample contains between 1

 19 larvae, one larvae can be misidentified and the sample will not fail the QC check.

c. If the identifying biologist identifies a larval fish to a certain family or genus and subsequently the identification QC biolo gist is able to refine the identification to a lower taxonomic level, this will not be considered a misidentification pertaining to the 95% identification accuracy level. A misidentification will be one in which the identifying biologist identifies the fis h as belonging to a certain family, genus or species, and then the identification QC biologist determines that the initial identification was incorrect and changes the identification to a different family, genus or species or changes it to a higher taxonom ic group. d.

B3 - 3 3.2 Larval Fish Measuring 3.2.1. Larval Fish Measuring Procedure

a. Turn on the computer, camera, and light source at the measuring station. b. Consult the lab schedule near the measuring station to determine measuring priorities and retrieve the binder co ntaining the appropriate data sheets.

c. Locate the box containing the fish to be measured and place it in a easily accessible area close to the measuring station. d. Open the Optimas Image Analysis or ImageJ software by clicking with the mouse on the appropriate software icon.

e. Open the Larval Fish Measuring macro in Optimas, or the FishMeasure2 macro in ImageJ and f o l l o w t h e m a c ro s ’ di re cti o n s
. f. Select the jar of fish to be measured and consult the jar label. Compare data on the jar label with the inner label and the data sheet for this sample. Consult an identifier regarding discrepancies between labels. g. Enter the data queried for by the macro including the last five digits of the serial number, the m e a s ur er ’ s ini ti al s , th e d at a sh e e t s e qu en c e numb er a n d th e sp e c ies code. h. Open the jar and remove the vials for the target taxa to be measured as per the posted list. Place the vials in a rack designed to allow the vials to maintain an upright posture so as to reduce spillage. i. Select the first vial to be measured. Remo ve the cotton and the label. Compare the label with the data sheet for confirmation. j. Empty the vial into a shallow dish. Remove any fish that have adhered to the vial, cotton, the label, or any tools used in the transferring process and place the fish in t he dish. Add alcohol to the dish if necessary to prevent desiccation. k. If the number of larval fish in the vial exceeds what can be reasonably measured on a single image capture, transfer some of the fish to another glass dish and immerse them in alcohol. l. P lace the dish on the stage of the microscope. Arrange the fish so that all fish appear on the screen. Adjust the zoom, focus, and lighting for the best possible image. If this is the first group of larval fish being measured, or if the magnification has be en changed, it is necessary to re

- calibrate. Place the micrometer on the stage of the microscope and re

- calibrate by drawing a line from one of the micrometers millimeter marks to another, noting the distance between the two marks, and entering that value when queried. Replace the dish containing the larval fish to be measured.

m. Measure larval fish by drawing a line from the pre

- maxillary to the end of the notochord, being careful to follow the contours of the fish. If the fish is too damaged to find either the pre - maxillary or to estimate the path taken by the notochord, do not measure, and proceed to th e n e xt l arv al f

B4 - 1 APPENDIX B4: IMPINGE MENT FIELD SAMPLING PROCEDURES 1.0 PURPOSE The purpose of this document is to identify the procedures and equipment necessary to accurately collect and process impingement samples at the Haynes Generating Station (HnGS).



### 2.0 RESPONSIBILITIES
2.1 Task/Field leader:

 Contact plant to obtain c learance for personnel that will be conducting the sampling.

 Verify that all investigating biologists conducting the sampling have read and understand these procedures.

 Verify that procedures have been followed during sample collection and that the samplin g has been conducted safely.
2.2 Investigating biologist:

 Conduct sampling using the following procedures.

### 4.0 PROCEDURES Impingement sampling will only be undertaken when there is water passing through the stationary/traveling screens of Units 1

- 6. If only one pump is in operatio n, proceed with sample collection using the following procedures. The bar rack area does not require daily cleaning, thus no collections will be conducted from this area. Each normal operation impingement survey consists of an initial cleaning period follo wed by four 6

- hr sampling cycles. Table B4

- 1 presents the proposed schedule for each survey. 4.1 Mobilization

a. Notify plant personnel of the dates, times, and names of the biologists that will be onsite during each survey. All personnel will require phot o i d enti f i c ati o n ( dri v er ’ s l i c en s e , p a s s p o rt , et c
. ) t o o b t ain a c c e s s to the plant site. b. The equipment listed in Table B4

- 2 is required for sampling and should be checked before leaving for the plant. Verify that any scales used for the sampling have been calibrated within the previous three months.

### Haynes Generating Station

IM&E Report Appendix B4: Impingement Field Sampling Procedure

B4 - 2 4.2 Traveling Screen Sample Collection Impingement sampling procedures will generally be the same at all units. However, Units 1&2 are equipped with stationary screens (Figure B4

- 1), which are more difficult to rin se, and will only be rinsed and cleaned prior to, and at the end of, the 24

- hour sampling period. Units 3

- 6, equipped with traveling screens (TS), will be rinsed and cleaned every 6 hours during the 24

- hr period (see Table B4

- 1). Figure B4

- 2 shows the coll ection sump area of Units 1&2 and Figure B4

- 3 shows the collection sump collection area of Units 3&4. The Unit 5&6 collection area is basically the same as the one for Units 3&4. The bar racks are located at the marina and are not cleaned on a regular basi s. They will not be cleaned during the weekly sampling.

a. Make sure that the collection basket has been emptied prior to the survey. If there is any debris in it, contact an operator to have them remove the basket using a crane so that it can be emptied. b. Th e initial screenwash is for cleaning purposes only; do not process any materials from the sump after the cleaning rinse. The time at the end of the initial TS rinse is the beginning of Cycle 1. Record this on the appropriate datasheet.

c. The mesh in the coll ection basket has a larger mesh than the mesh of the TS. Secure a mesh net/vexar basket (with mesh of the same size or smaller than the TS mesh) inside of the metal basket so that impinged materials can easily be removed. If the debris load is too heavy fo r the mesh net/vexar basket or it is damaged and materials accumulate in the metal basket, make sure an operator is available to use a crane to pull the metal basket out for sample collection. d. Have plant personnel activate the TS wash system thirty minutes prior to the end of each cycle so that all impinged material is rinsed from the screens into the collection basket.

e. Remove all impinged fish and invertebrates from the impinged debris. f. Replace the mesh net/vexar basket in the rectangular sump before initi ation of the screenwash for the next cycle. g. All collected impinged material will be processed using the procedures in following section. 4.3 Sample Processing

a. Remove all fishes and invertebrates from the impinged debris. Record the volume of the debris (gallon s) on the datasheet. Also record the composition and percentage of the debris. b. All fishes, crabs, shrimps and prawns, and cephalopod mollusks are identified, counted, measured (see measurement criteria below), and weighed. This information is recorded on t he appropriate datasheet. A l l o th er i nv ert eb rat e s a

Make certain of all identifications before recording the name on the datasheets. If an organism cannot be positively identified it should be saved. The voucher specimen should be placed in a plastic bag

e. If a large number (more than 30) of any individual countable species is collected during a cycle, individually measure and weigh 30 randomly selected individuals of this specie s and then count and measure the remaining individuals and record this information on a separate line on the datasheet.

- mutilated individuals, record the weight of the mutilated individual(s) but not their length s. h. Record any anomalies or other notes (encountered in each cycle) in the notes section on the datasheet. i. At the end of each cycle verify that: a) the sampling procedures have been followed correctly, b) the data has been recorded correctly and legibly, an d th en c ) s i gn an d d at e th e “ Re vi ew e d b y /D at e ” s e cti on at the bottom of the datasheet. j. Put all dead animals and discarded debris in trash dumpsters. Make sure to double bag the material as collection of the trash may not occur for several days. k. Quality con trol (QC) checks will be preformed on at least a quarterly basis to verify all organisms are being removed from the debris and that the correct identification, enumeration, length and weight measurements of the organisms are being recorded on the datasheet . The QC team will randomly choose the actual impingement cycles that will be checked and will resort the debris for any missed organisms. All organisms will then be identified, re

- measured and re

- weighed by the QC team to ensure that the data is being rec orded correctly. If a sampling team fails a QC check, they will be retrained on fish identification and sample collection. QC checks will be performed on the sampling team until they pass the QC requirements. The QC checks will be fully documented and repo rted to the Project Manager. 4.4 General

a. All information recorded on the datasheets must be written legibly with a pencil. b. Keep information separate for each cycle

c. The survey number will be determined based on the week corresponding to that survey (e.g., wee k 1 = survey 1). Make sure the correct survey number is recorded. d. Make certain that the unit #s and cycle numbers are correct on the datasheet you are using. Record the date and time for the start and end of each screen wash (generally 15 to 20 minutes) an d cycle duration times (generally 6 hours). Each 24

- hr survey is divided into 4 six

- hour cycles.

e. Record the names of all personnel present during each cycle.

### Haynes Generating Station

IM&E Report Appendix B4: Impingement Field Sampling Procedure

B4 - 4 f. Use military time (0000

– 2400) to record every cycle collected. Record all times as local time (P acific Standard Time or Pacific Daylight Time). g. During each screen wash, verify that the screens are operating properly (the screens should be moving and the water should be spraying). Check with the operator to find out how many circulating water pumps are operating. h. If a survey cannot be completed or is cancelled, make a note on the appropriate data sheet explaining the reason for the cancellation. Write the survey number that corresponds to that week, date and sign the datasheet. i. At the end of each scree n wash, record the relevant meteorological data. j. If the traveling screens trip before the 6

- hour cycle is over, collect all material and process it as part of the upcoming cycle. If possible, have the screen wash system run at the scheduled times. 4.5 Heat Tre atments During heat treatments follow the same procedures as during normal impingement sampling. Use a separate data sheet for each species collected. A single data sheet can be used for several species if low numbers of these species are collected. If an extremely large amount of material is collected in the sump basket, sub

- sampling of the most abundant fishes/shellfishes should occur to minimize the time taken to process the sample. Sub

- sampling procedures are as follows:

a. Remove the less abundant fishe s/shellfishes from the impinged material; and record as individuals on the datasheets. b. Collect a sub

- sample (for example, two 3

- gallon sub

- samples) from the pile of impinged material. Make sure to randomly sample the pile by collecting organisms from different areas of the pile. Discard the remaining material and record the volume discarded on the data sheets.

c. The number and weight of the organisms collected from each sub

- sample should not be recorded with the other data. Record the sub

- sample data on a separate datasheet. Make certain that record of the organisms from the sub

- samples can be linked back to the quantity of material discarded and not sampled.

The following se

ction describes calculations used for assessing entrainment effects at the Haynes Generating Station (HnGS). The equations are presented in a general form that is applicable to sample designs that may have differing numbers of stations, sampling periods, o r replicates. The HnGS entrainment study will sample only one station. While the summation signs over stations are presented in the equations they will be summing over an n of one in the actual calculations and therefore will drop out of the formulas. A general form can be written for summing entrainment over stations at an intake or entrainment site using cycles within a day and days within time periods. Let

The empirical transport model ( ETM ) is used to estimate the total mortality probability for larvae from power plant entrainment. The estimate is based on periodic estimates of the probability of entrainment mortality based on daily samples. In the following calculations we assume all larvae entrained die. Generally, sampling takes place over the course of a year so that larval mortality of various species is estimated. The daily probability of entrainment can be defined as

# Appendix C3 Demographic Model Calculations Fecundity Hindcasting ( FH )
The estimated total larval entrainment for a species ( **** T 

### E 

### ) was used to estimate the number of breeding females needed to produce the number of larvae entrained. The estimated number of breeding females ( ****

### Equation C1 is based on the simplified case of a single synchronized spawning by a species. For species with overlapping or continuous spawning, larval abundance would have to be specified by week and age class (i.e., **** ij 

### E 

### ). However, we used the mean size of all larvae entrained to estimate a representative age of larvae, and then estimated a survival rate to this representative age. Two input parameters in Equation C1 that may not be available for many species, and thus may limit the method, are lifetime fecundity ( TLF 

### ) and survival rates ( i 

### S 

### ) from spawning to entrainment. In practice, survival was estimated by either one or several age classes, depending on the data source, to the estimated age at entrainment. The expected total lifetime fecundity ( ) E TLF 

### was approximated by modeling a linear survivorship for a female once she reached the age of maturity, and using a constant number of eggs produced per year.

The expected length of reproductive life was approximated as the midpoint between the times of maturation and longevity. The approximation of linear survivorship between these events implies uniform survival. For exploited species such as northern anchovy and sardine, the expected number of years of reproductive life may be much less than predicted using this assumption.

- specific survival rates from larval stage to recruitment into the fishery were available, AEL was calculated using survival from a representative age of the entrained larvae at HnGS. This age was calculated by dividing the average larval length at entrain ment (minus hatch length) by a literature

However, information describing adult stocks is limited for many species, and independent field estimates of survival from time of entrainment to adulthood are not available for some species. For some species where such information is unavailable, we can estimate this parameter by assuming a stationary population where an adult female must produce two adults (i.e., one male and one female).

These comparisons serve as a method of cross
