Appendix A1

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 SGS. Two Nortek Aquadopp® acoustic Doppler current

profilers (ADCPs) were positioned in separate locations, one (CM 3) approximately 2.3 km (1.4 mi) from

shore at a depth of 24.4 m (80.0 ft) MLLW, and a second unit (CM 4) approximately 1.1 km (2.0 mi)

from at a depth of –12.8 m (41.9 ft) MLLW. The latitudes and longitudes of the two stations were

33.89020oN, -118.44324oW and 33.89442oN, -118.43126oW. Both stations were commissioned on

January 10, 2006. Station CM 3 was decommissioned on January 12, 2007 and Station CM 4 was

decommissioned on January 22, 2007. Data were downloaded on February 3, 2006, May 3, 2006, and

July 18, 2006, and September 1, 2006. The unit at CM 4 had an operating frequency of 1 MHz, while the

unit at CM 3 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.

APPENDIX B1: PROCEDURE FOR COLLECTING 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 Scattergood Generating Station (SGS).

2.0 RESPONSIBILITIES

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 biologist:

 Conduct sampling using the following procedures.

4.0 PROCEDURES

4.1 Mobilization

 Notify plant personnel of the dates of field sampling prior to the sampling day.

 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.

 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.

 Ensure that all additional equipment (Table 1) is in good operating condition. Make repairs if

necessary.

4.2 Sample Collection
Scattergood Generating Station

IM&E Final Report Appendix B1: Entrainment Sampling Procedures

B1-3

 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.

 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.

 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.

 Record each flowmeter’s serial number on the field data sheet (Attachment 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.

 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.

 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.

 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.

 Record the end time (local time) on the field data sheet.

 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.

 Detach the codend from net #1 and rinse the sample from the codend into a labeled sample jar using a

squirt bottle containing sea water. 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.

 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.

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

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

jar labels:

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

(SMBEA##). The first three letters are “SMB” refers to Santa Monica Bay, and the “EA” refers to

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.
Scattergood Generating Station

IM&E Final Report Appendix B1: Entrainment Sampling Procedures

B1-4

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

letter/numbering system was set up for all three Santa Monica Bay generating stations

(Scattergood, El Segundo, and Redondo Beach). The first letter refers to the station being an

Outer, Mid, Shore, Harbor, or Entrainment station (see map in Attachment 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 1-5

Mid 1-3

Shore 1-7

Harbor 1-2

Entrainment 1-4

c) Entrainment Station E1 is located near Scattergood’s intake structure, E2 and E3 are at El

Segundo, and E4 is at Redondo Beach.

d) The second letter designates the replicate, either “A” or “B”. The source water stations only have

one sample so always use the letter “A”. There are two samples collected at the entrainment

location so the letters “A” and “B” will be used to separate these two replicates. The second

number designates the net number, either “1” or “2.” For example, O3A1 means that the sample

was collected from Station O3, Sample A, and Net 1.

e) 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.

 Deliver the samples to the laboratory at the completion of the sampling effort.

4.3 Sample Voiding in the Field

 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.

 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.

 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 Scattergood Power Plant, 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

(Attachment 5.1).

b. Transfer the samples to be sorted to the laboratory trailer.

c. Samples that were originally fixed in formaldehyde after collection, must be

transferred to 100% ethanol before laboratory processing. This is done

outside to lessen the exposure to formaldehyde fumes.

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 100% 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.

d. Consult the sorting schedule posted in the processing laboratory to determine

sorting priorities.

e. Sign out the sample on the Laboratory Sample Tracking Sheet (Attachment 5.2)

by writing your initials under the ‘sorter’ column. Transcribe information

from the sample label into the Sorter’s Log Book (Attachment 5.3) and into
Scattergood Generating Station

IM&E Final Report Appendix B2: Entrainment Sample Sorting Procedures

B2-2

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

this purpose).

f. Take two clean canning funnels with attached mesh netting, one labeled ‘sorted’

and the other labeled ‘unsorted’. The mesh size should be no larger than that

used to collect the samples.

g. Place the ‘unsorted’ canning funnel on a clean jar. Next, place the jar and funnel

in a dish so samples can be retrieved if spillage occurs. Pour a sample into the

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

will drain into the jar.

h. Place the ‘unsorted’ funnel on a second jar or can. Using fresh water in a

squeeze bottle, rinse any remaining sample from the sample jar, the jar lid and

inner sample label into the funnel containing the unsorted sample.

i. Pour the ethanol that was filtered through the canning funnel into the original

sample jar. Keep the original ethanol-filled sample jar with the sample.

Dispose of the alcohol waste-water from the second jar into the appropriate

waste container.

j. Place the ‘unsorted’ funnel containing the sample and the empty ‘sorted’ funnel

into individual glass bowls in a tray. Do not let the sample dehydrate during

processing.

k. Transfer a small amount of the sample from the ‘unsorted’ funnel to the sorting

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

sorting tray.

l. 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.

m. Arrange the light source to provide adequate illumination.

n. 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

70-80% ethanol or into a small dish containing water.

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

p. 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.

q. Once sorted, pour the sorted sample into the ‘sorted’ funnel and rinse with a

small amount of water. Take a second aliquot from the ‘unsorted’ funnel as

described above. Repeat the above steps until the entire sample has been

sorted.

r. When the sorting has been completed, the sorted organisms should be placed

into a shell vial containing ethanol. Place cotton into the top end of the vial to

keep the organisms inside. Place the vial into a labeled jar containing ethanol.

s. Add enough ethanol to at least cover the shell vials and label each jar lid with a

colored dot label. (The jar lid color coding system is posted in the lab.)

Prepare a waterproof inner label for the jar containing the shell vial. Both

labels should contain the following information:

1. Serial number

2. Date the sample was collected
Scattergood Generating Station

IM&E Final Report Appendix B2: Entrainment Sample Sorting Procedures

B2-3

3. Station, cycle and sample number

4. Collection start time

5. Jar number (if more than one jar)

6. Sorter’s initials

7. Number of organisms in shell vial

t. The total number of sorted organisms and the total time required to process the

sample is recorded in the sorter's notebook.

u. Put the sorted sample back into the original sample jar containing the ethanol.

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 the remaining sample.

v. For samples that do not contain any larval fish, an empty jar is labeled with the

above information with zero (0) organisms indicated, and placed in the

appropriate storage location.

w. 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. Put the unsorted sample into a second jar. Rinse any sample from the

‘unsorted’ funnel into the jar using a squirt bottle containing ethanol.

Using a dot label, label the jar lid with the sample identification

information, sorter’s initials, and the word “unsorted”. Make an

additional inner label with the sample identification information and

marked ‘unsorted’. Place the label inside the jar with the ‘unsorted’

sample. Make certain that the ‘unsorted’ sample is adequately covered

with ethanol.

3. The sorted and unsorted portion of the sample should be stored in a

flammable materials storage cabinet 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 Laboratory

Sample Tracking Sheet (Attachment 5.2), and to the Sorter's Log (Attachment

5.3).

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 sorter has passed 10 consecutive sorts, the program is switched to a ‘1

sample in 10’ QC program for that sorter. After the sorter has completed

another 10 samples, one sample is randomly selected by the designated QC

sorter for a QC resort.
Scattergood Generating Station

IM&E Final Report Appendix B2: Entrainment Sample Sorting Procedures

B2-4

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

sorter continues in the ‘1 sample in 10’ QC mode.

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 a 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 record them as # fish

/ # fragments in the sorter’s notebook and on the tracking sheet.

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” added to the label.

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

was resorted and labeled with the QC person’s initials, survey number,

sample number, and date 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.

4.0 RECORDS

4.1 All data sheets are later reviewed, initialed, and coded by the Task Leader or his designate, and

submitted to the Data Coordinator for logging, computer entry, and storage.

4.2 Original data sheets are permanently stored.

APPENDIX B3: PROCEDURES FOR THE IDENTIFICATION OF

LARVAL FISHES and TARGET INVERTEBRATES

1.0 PURPOSE

The purpose of these procedures is to define the steps for identifying planktonic organisms, and to describe

the Quality Control (QC) Program used to monitor the accuracy of each individual’s identification

performance.

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 and target invertebrate larvae.

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

organisms is available (Attachment 5.1).

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. Sign out the sample to be identified by placing your initials in the “ID’er”

column on the Laboratory Sample Tracking Sheet (Attachment 5.2).

d. 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.

e. 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 5.3).

f. 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.

g. 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.

h. All vials containing target organisms froman 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 collected, and identifier’s initials.

Tighten the jar lid to prevent evaporation of the preservative. Samples with

many different fish taxa may require more than one labeled jar.

i. On the Laboratory Sample Tracking Sheet, record the identifier’s initials and

date sample was logged in. The identifier’s log will contain the total number

of larvae identified and the date identified. If more than one day was needed
Scattergood Generating Station

IM&E Final Report Appendix B3: Entrainment Sample Identification Procedures

B3-2

to complete the identification, record the date the sample identification was

completed.

j. Place the jar into the appropriate box containing identified samples.

k. Dispose of any liquids containing ethanol into the appropriate waste container.

3.2 Identification Quality Control (QC) Program

3.2.1 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

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 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 “1 sample in 10” QC program. After the identifying biologist

has completed another 10 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, then the identifying biologist continues in the “1

sample in 10” QC mode. If a 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.

3.2.2 Invertebrate Larvae

a. The first ten samples identified by an individual identifying biologist will be

completely re-identified by a designated identification QC biologist.

b. The identifying biologist must maintain a 95% 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. After the identifying biologist has passed 10 consecutive samples, the program

is switched to a “1 sample in 10” QC program. After the identifying biologist

has completed another 10 samples, one sample is randomly selected by the

designated identification QC biologist for a QC review.
Scattergood Generating Station

IM&E Final Report Appendix B3: Entrainment Sample Identification Procedures

B3-3

d. If this sample maintains the 95% accuracy level as determined by the

identification QC biologist, then the identifying biologist continues in the “1

sample in 10” QC mode.

e. If an identifier’s sample does not meet the 95% accuracy level, their subsequent

samples will be re-identified until 10 consecutive samples meet this level.

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

into the appropriate labeled vial for that sample and recorded on the

appropriate laboratory identification data sheet.

3.3 Larval Fish Measuring

3.3.1 Larval Fish Measuring Procedure

a. Turn on the computer, camera, and light source at the measuring station.

b. Consult posted notices 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 software by clicking with the mouse on the

Optimas icon.

e. Open the Larval Fish Measuring macro in Optimas, and follow the macro’s

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’s initials, the data sheet sequence number and the

species 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 fifty or 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.

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 the next larval fish. If the line does

not adequately approximate the larval fish’s length it must be re-measured.

n. Note the program’s display of the measurement, check that it seems reasonable.

If it does not seem reasonable, it may be necessary to re-calibrate and remeasure. If the problem persists, contact an identifier. Make note of any

problems in measuring and post near the measuring station.

o. The macro will store the measurement in at least two separate data files along

with the necessary sample information.

p. Repeat the above steps for all fish in the dish.

q. When all larval fish in the dish have been measured, fill the vial that originally

contained the fish with alcohol and transfer the measured fish to the vial.

r. If the larval fish from this vial have been segregated into two or more groups,

place another group into the dish, being careful to submerse them in alcohol,

and measure as above. Do not measure more than fifty larval fish of any one

taxon from each sample.

APPENDIX B4: IMPINGEMENT 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 Scattergood Generating Station (SGS).

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 SGS CONTACT INFORMATION

On-Site Emergency Number (310) 524-8300 On-site # 48300

4.0 PROCEDURES

Impingement sampling will only be undertaken when there is water passing through the traveling screens

for Unit 1,2 or 3. If only one pump is in operation, proceed with sample collection using the following

procedures. Each normal operation impingement survey consists of an initial cleaning period followed by

four 6-hr sampling cycles. Table B4-1 presents the target 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 a photo identification (driver’s license,

passport, etc.) to obtain access 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.

4.2 Traveling Screen Sample Collection

a. Material impinged at Units 1-2 and Unit 3 is rinsed from the traveling screens (TS) into

metal collection baskets placed in one of two sumps (Figures B4-1 and B4-2). The bar rack

area does not require daily cleaning, thus no collections will be conducted from this area.
Scattergood Generating Station

IM&E Final Report Appendix B4: Impingement Procedures

B4-2

b. 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.

c. 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.

d. 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.

e. Have plant personnel activate the TS wash system thirty (30) minutes prior to the end of

each cycle so that all impinged material is rinsed from the screens into the collection basket.

f. Remove all impinged fish and invertebrates from the impinged debris.

g. Replace the mesh net/vexar basket in the rectangular sump before initiation of the

screenwash for the next cycle.

h. 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. All other invertebrates are identified and recorded as present by

entering a “P” in the count box.

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

Spiny lobster

and Shrimps

Carapace length, measured from the anterior margin of carapace

between the eyes to the posterior margin of the carapace

Octopus Maximum “arm” spread, measured from the tip of one tentacle 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 personnel on the next cycle can positively identify the

organism record the organism’s name on the datasheet. If positive identification cannot be

made the organism is returned to the laboratory for identification.
Scattergood Generating Station

IM&E Final Report Appendix B4: Impingement Procedures

B4-3

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 anchovies were collected, randomly select 30

individuals and record on the first row Engraulidae, 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 = “-“ (if the sex cannot be

determined without dissection, record a “-“), and condition = alive (A), dead (D), or

mutilated (M). Continue this procedure for the other 29 randomly chosen anchovies. Then

individually measure, but batch weigh, the remaining individuals (up to 200). In instances

where more than 200 individuals of any species are impinged during one cycle, record a

batch weight for the rest of the individuals of that species. If all of the individuals are alive,

put an “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 for juveniles, G for gravid. Put a “-“ if

the sex cannot be 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 nonmutilated 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, and then c) sign and date the

“Reviewed by/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, remeasured and reweighed 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 (eg.,

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.

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

Scattergood Generating Station (SGS). 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 SGS 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

The individual variances within Formula B8 describe temporal-spatial variance in density within

the source population during the day of sampling. Seven source water locations are sampled in

due to sampling a large area required a directed and fixed time and location sampling scheme.

Demographic Model Calculations

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 class j 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 DCPP.

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

( ) ST 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.
