Source Water Currents

Physical oceanographic data were collected from the source water body to describe current regimes that

can affect larval transport in the vicinity of the HnGS. Two Nortek Aquadopp® acoustic Doppler current

profilers (ADCPs) were positioned in separate locations in San Pedro Bay, one (CM1) approximately 2.1

km (1.3 mi) from shore off the entrance to Alamitos Bay at a depth of 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

corrected for sea level.

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 they 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.

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 flowmeters are securely attached. The nets should be

333-μm mesh.

d. Recordeachflowmeter’sserialnumberonthefielddatasheet(AttachmentB1-1). Record the number

from the flowmeter counter spins on the field data sheet prior to lowering the frame into the water.

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, the 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 sediment 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 verify 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 readings 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%-formalin seawater solution. Rinse and inspect the codend of net #1

before reattaching to the net. Follow the same procedure for net #2. Sample preservation should be

completed soon after collection.

k. If the collected material will fill over 1⁄2 of the sample jar, split the sample into at least two labeled jars

so that there is enough ethanol for proper preservation.

l. Ensure that the sample jar contains both an inner label and an exterior label.

m. The following is an explanation of the coding for the field datasheet survey and station numbers and

jar labels:

1. Each survey number on the data sheet consists of a series of 5 letters followed by 2 numbers

(ABEA##).Thefirsttwolettersare“AB”referstoAlamitosBay,andthe“EA”refersto

entrainment abundance. The two numbers refer to the survey number with the first survey being

01. The survey number increases by one for each new 24-hour sampling effort.
Haynes Generating Station

IM&E Report Appendix B1: Entrainment Field Sampling Procedure

B1-4

2. The station designation consists of a letter-number-letter-number combination. This

letter/numbering system was set up for all two Alamitos Bay generating stations (Alamitos and

Haynes). The first letter refers to the station being an Outer, Shore, Harbor, or Entrainment station

(see map in Attachment B1-2). The first number refers to the number of the station that links to the

station letter. The numbers for each of the stations listed above are as follows:

Station letter Station number

Outer 1-3

Shore 1-3

Harbor 1-4

Entrainment 1-3

3. Entrainment Stations E1 and E2 are located near AGS intake structures and E3 is at HnGS.

4. The second letter designatesthereplicate,either“A”or“B”.Thesourcewaterstationsonlyhave

5. The date of sampling will correspond to the actual start date of each sample. At the start of a new

day (midnight), use a new field data sheet.

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) gear 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.

APPENDIX B2: PROCEDURE FOR SORTING PLANKTON SAMPLES 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 exposure 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 and 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)bywritingyourinitialsunderthe‘sorter’column.

Transcribe information from the sample label into theSorter’sLogBook(AttachmentB2-2)

and into the sorter's notebook (each sorter has separate log sheets and a notebook for this

purpose).

e. Taketwocleancanningfunnelswithattachedmeshnetting,onelabeled‘sorted’andthe

canning funnel. The canning funnel will contain the material to be sorted, while the ethanol

willdrainintothe‘usedalcohol’bottle.

g. Using 70% ethanol or 70% used alcohol in a squeeze bottle, rinse any remaining sample

from the sample jar, the jar lid and inner sample label into the canning funnel containing the

unsorted sample.

h. Placethe‘unsorted’funnelcontainingthesampleandtheempty‘sorted’funnelinto

individual glass bowls in a tray. Make sure the sample is covered with water so it will not

dehydrate during processing.

i. Usingforceps,transferasmallamountofthesamplefromthe‘unsorted’funneltothe

sorting tray. Add enough water to cover the sample. Distribute the sample in the sorting tray.

j. Place the sorting tray on the base of the dissecting microscope. 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 orientation. 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.

o. Oncesorted,pourthesortedsampleintothe‘sorted’funnelandrinsewithasmallamountof

water.Takeasecondaliquotfromthe‘unsorted’funnelasdescribedabove.Repeatthe

above steps until the entire sample has been sorted.

p. If the sorter thinks there will be more than 500 fish eggs in a sample then the sample may be

“subsampled”foreggs.When“subsampling”thesampleshouldbeprocessedfirstforfish

larvaeandselectedinvertebratelarvae.Whenreadyto“subsample”putthe sorted sample

back in the original sample jar and fill the jar with 70% ethanol up to the lip of the jar. Jar

size varies, but they will typically be 500 ml (if sizes varies there will be a posting in the

lab).A‘subsample’shouldbe10%ofthesamplevolume so the sorter will use the aliquot

transfer pipette with the 10 ml attachment and take 5 aliquots. 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

sampledate,and“SS”.

q. When the sorting has been completed, the sorted organisms should be placed into a shell vial

containing 70% ethanol. Fill the shell vial completely with clean 70% ethanol then place

cotton into the top end of the vial to keep the organisms inside. Place the vial into a labeled

snap cap containing 70% ethanol. Make sure the shell vial and cotton are completely

covered with 70% ethanol.

r. Label each jar lid with the appropriate colored dot label. Prepare a waterproof inner label for

the jar containing the shell vial. Both labels should contain the following information:

1. Survey number

2. Collection date

3. Station, cycle and sample number

4. Collection start time
Haynes Generating Station

IM&E Report Appendix B2: Entrainment Sample Sorting Procedure

B2-3

5. Jar number (if more than one jar)

6. Sorter’sinitials

7. Number of organisms in shell vial

s. The total number of sorted organisms and the total time required to process the sample is

recorded in the sorter's notebook.

t. Put the sorted sample back into the original sample jar. Used alcohol may be used to fill

sample jar to at least 3⁄4 full. Rinse any remaining sample from the funnel into the jar using a

squirt bottle containing ethanol. Make sure the inner waterproof label is in the sample jar.

Thoroughly clean the funnels of all remaining sample.

u. If a sample must be stored before completion:

1. Put the sorted portion of the sample back into the original sample jar. Rinse any

remaining material from the funnel into the jar using a squirt bottle containing ethanol.

Make sure that the sample is adequately covered with ethanol.

2. Puttheunsortedsampleintoasecondjar.Rinseanysamplefromthe‘unsorted’funnel

into the jar using a squirt bottle containing ethanol. Using a dot label, label the jar lid

withthesampleidentificationinformation,sorter’sinitials,andtheword“unsorted”.

Make an additional inner label with the sample identification information and marked

‘unsorted’.Placethelabelinsidethejarwiththe‘unsorted’sample.Makecertainthat

the‘unsorted’sampleisadequatelycoveredwithethanol.

3. The sorted and unsorted portion of the sample should be stored until sorting can

continue.

3.1.2 Once the sample is completed, place an appropriately colored dot label on the jar top with the

sorter's initials and date of sorting. Return the jar to the box from which it was originally

removed.

a. Transcribe the information recorded in the sorter's notebook to the computer on the

Laboratory Tracking Sheets and the Quality Control log and on the Laboratory Sample

Tracking Sheet (Attachment B2-1), and to the Sorter's Log (Attachment B3-2).

3.2 Sorting Quality Control Program

3.2.1 QC Sorting Criteria

a. The first ten samples that are sorted by an individual are completely resorted by a designated

QC sorter. A sorter is allowed to miss one target organism when the original sorted count is

119. For original counts above 20 a sorter must maintain a sorting accuracy of 90%.

b. After the sorterhaspassed10consecutivesorts,theprogramisswitchedtoa‘1samplein

10’QCprogramforthatsorter.Afterthesorterhascompletedanother10samples,one

sample is randomly selected by the designated QC sorter for a QC resort.

c. If the sorter maintains the 90% accuracy sorting rate for this sample, then the sorter

continuesinthe‘1samplein10’QCmode.

d. If a sample does not meet the 90% accuracy rate their subsequent samples will be resorted

until 10 consecutive samples meet the criteria.

3.2.2 QC Resorting

a. Sorting procedures used during the QC resort are the same as the sorting procedures

described in Section 3.1.

b. All fish and selected invertebrate larvae that were missed by the sorter are removed during

the QC resort.

c. For the QC process, a larval fish is defined as having a head plus at least 50% of the body.

Any parts without a head and/or less than 50% of the body will be considered fragments and

will not be counted against the original sorter as a missed fish. However, it is important for

each sorter to remove all fish and fragments from each sample that is sorted and correctly

recordthemas#fish/#fragmentsinthesorter’snotebookandonthetrackingsheet.

d. Any vials of fish larvae or selected invertebrate larvae generated from the resort are labeled

with an orange dot label, and labeled as described in the sorting procedures with the addition

of“QC”addedtothelabel.

e. An orange dot label should also be placed on the top of the jar of the sample that was

resortedandlabeledwiththeQCperson’sinitials,surveynumber,samplenumber,anddate

the resort was completed.

f. The vials are stored in the appropriate location.

3.3 Waste Disposal

3.3.1 No formaldehyde or water contaminated with formaldehyde should be disposed of into the

sewage system. Dispose of any water contaminated with this chemical in the designated waste

water container to be disposed of at a local hazardous materials waste depository.

2.0 RESPONSIBILITIES

 The Lead Taxonomist is responsible for assuring that plankton identifications are performed in

accordance with written procedures and for implementing the Quality Control Program.

 Investigating biologists are responsible for plankton identifications and for monitoring accuracy in

accordance with written procedures.

3.0 INSTRUCTIONS

3.1 Identification procedures for larval fishes, Cancer spp. crab and Panulirus lobsters.

a. Ensure that the proper equipment necessary for the identification of target organisms is

available (Table B3-1).

b. The fish and target invertebrates from each sample are kept in separate containers and

processed following this procedure in essentially the same manner.

c. The container of target organisms to be identified is carefully emptied into a dish. The dish is

placed on the microscope stage and the lighting adjusted to provide adequate illumination.

d. Each target organism is identified to the lowest taxonomic classification possible. The total

number of each taxon is recorded on the Entrainment /Source Water Plankton Tow Lab Data

Sheet (Attachment B3-1).

e. All individuals of each identified taxon of larvae from a sample should be put into a shell vial

containing 100% ethanol. Each vial should contain a label with the taxon name and sample

number. Cotton should be pushed into the upper end of the vial to keep the label and

organisms enclosed.

f. Mutilated larvae (partial organisms that are missing body parts and are unable to be

identified) are placed in a separate labeled vial. Whole larvae that are unidentified, are placed

in a separate labeled vial.

g. All vials containing target organisms from an individual sample should be put into a labeled

jar containing enough ethanol to cover the vials. The jar should contain both an inside label

and a label attached to the outside of the lid denoting the sample number, date and time

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 ten samples. If

the first 10 consecutive samples do not pass the 50/5 criteria, additional samples must be reidentified 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 biologist 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 fish 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 taxonomic

group.

d. After the identifying biologist has passed 10 consecutive samples, the program is switched to

a“1samplein10”QCprogram.Aftertheidentifyingbiologisthascompletedanother10

samples, one sample is randomly selected by the designated identification QC biologist for a

QC review.

e. If this sample maintains the 95% accuracy level as determined by the identification QC

biologist,thentheidentifyingbiologistcontinuesinthe“1samplein10”QCmode.Ifa

sample does not meet the 95% accuracy level, their subsequent samples will be re-identified

until 10 consecutive samples meet this level of accuracy.

f. Any misidentified fish found by the identification QC biologist, will be placed into the

appropriate labeled vial for that sample. This information will be recorded on the Fish

Identification Data Sheet.

3.1.3 Cancer spp. and Panulirus spp.

a. The first ten samples identified by an individual identifying biologist will be completely reidentified by a designated identification QC biologist.

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 containing 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

followthemacros’directions.

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

measurer’sinitials,thedatasheetsequencenumberandthespecies 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. Remove 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 the 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. Place 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 been 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.

APPENDIX B4: IMPINGEMENT 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 clearance 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 sampling has been

conducted safely.

2.2 Investigating biologist:

 Conduct sampling using the following procedures.

3.0 HnGS CONTACT INFORMATION

Name Cell/Outside Line E-mail Information

Alex Gima (310) 522-7513 alex.gima@ladwp.com

On-Site Emergency Number 27300

Operating Supervisor (310) 52-27507

Station Control Operator (310) 52-27510

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 operation, 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 followed 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 photoidentification(driver’slicense,passport,etc.)toobtainaccess

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 rinse, 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 collection 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 basis. 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. The 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 collection 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 for 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 initiation 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

(gallons) 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 the appropriate datasheet.

Allotherinvertebratesareidentifiedandrecordedaspresentbyenteringa“P”inthecountbox.

Organism Group Length Measuring Criteria

Fishes Total body length for sharks, disc width for skates and rays and

standard lengths for bony fishes

Crabs Maximum carapace width

Octopus Maximum“arm”spread,measuredfromthetipofonetentacle to the

tip of the opposite tentacle

Squid Dorsal mantle length, measured from the edge of the mantle to the

posterior end of the body

c. Record all organism names on the appropriate datasheet, using their scientific names whenever

possible. The taxa codes are recorded after the datasheets are returned to the office.

d. 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

with a waterproof label indicating the location, cycle, date, time, and the initials of the collector. If

personnelonthenextcyclecanpositivelyidentifytheorganismrecordtheorganism’snameonthe

datasheet. If positive identification cannot be made the organism is returned to the laboratory for

identification.

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 species and then count and

measure the remaining individuals and record this information on a separate line on the datasheet. For

example: if 198 deepbody anchovies were collected, randomly select 30 individuals and record on the

first row Anchoa compressa, count = 1, Length = standard length (the distance from the tip of the snout

to the posterior vertical margin of the hypural plate) to the nearest mm, weight = weight to nearest

gram,sex=“-“(ifthesexcannotbedeterminedwithoutdissection,recorda“-“),and condition = alive

(A), dead (D), or mutilated (M). Continue this procedure for the other 29 randomly chosen deepbody

anchovies.Thenbatchweightheremainingindividual.Ifalloftheindividualsarealive,putan“A”in

the Cond. box. If some are dead and some mutilated, use additional rows to fill in the appropriate

information in the corresponding row(s).

f. Determine the sex of the countable organisms to the extent possible without dissection. Assign the

letter M to refer to males, F for females, J forjuveniles,Gforgravid.Puta“-“ifthesexcannotbe

determined without dissection.

g. Record the condition of each countable organisms: A for alive; D for dead; M for mutilated. If an

individual is mutilated, do not measure the length. If there are more than 30 non-mutilated individuals,

the mutilated individual(s) can be weighed with the batch weight of the additional individuals. If there

are less than 30 non-mutilated individuals, record the weight of the mutilated individual(s) but not their

lengths.

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, andthenc)signanddatethe“Reviewedby/Date”section

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 control (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 recorded 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 reported 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., week 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) and 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 (Pacific

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 screen 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 Treatments

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 fishes/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.

Appendix C1

Estimating Total Entrainment

The following section 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, or 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

i = period i N 1, ,  ;

j = day within period j N 1, ,  i;

k = cycle within day k N 1, ,  ij ;

l = station l N 1, ,  ijk;

m = volume at station within cyclem N 1, ,  ijkl.

This summation assumes that stations represent the total intake volume of the power plant. It also

assumes that the larval density in the volume of water passing a station is constant over time and

space over any cycle. An estimate of the total larval entrainment can be made by taking ijkl n

Appendix C2

Estimating Proportional Entrainment

and the ETM Calculations

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

Fecundity Hindcasting (FH)

The estimated total larval entrainment for a species ( ET) was used to estimate the number of

breeding females needed to produce the number of larvae entrained. The estimated number of

breeding females ( FH ) whose fecundity was equal to the estimated total loss of entrained larvae

is calculated as follows:

eggs spawned per female over their reproductive years.

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., Eij ). 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 ( iS ) 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.

Simulation, comparing exponential survival, shows that the calculation of TLF  will be

negatively biased for species with short reproductive lifespans, and positively biased for those

with longer durations.

Adult Equivalent Loss (AEL)

The AEL approach uses estimates of the abundance of entrained or impinged organisms to

forecast the loss of equivalent numbers of adults. Starting with the number of age classj larvae

entrained ( Ej), it is conceptually easy to convert these numbers to an equivalent number of

adults lost ( AEL) at some specified age class from the formula:

Age-specific survival rates from larval stage to recruitment into the fishery (through juvenile and

early adult stages) must be included in this assessment method. For some commercial species,

survival rates are known for adults in the fishery; but for most species, age-specific larval

survivorship has not been well described.

When age-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 entrainment (minus hatch length)

by a literature-based growth rate. Age-specific survivorship for any interval of time (t) was then

calculated following the formula (Ricker 1975)

An alternative analysis would be to compare AEL with the size of the adult population of

interest or with fishery harvest data. This method converts numbers of adult losses into fractional

loss of the population of interest (e.g., stock assessment). 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). Overall survival

( ) TS can then be estimated from total lifetime fecundity (TLF ) by the quantity

The estimates of mortality calculated from the AEL and FH approaches can be compared for the

same time periods for taxa where independent estimates are available for (1) survival from

entrainment to recruitment into the fishery and (2) entrainment back to hatching. These

comparisons serve as a method of cross-validation for the demographic approaches to impact

assessment.
