# 1.0 INTRODUCTION

Section 316(b) of the Clean Wa ter Act requires that cooling water intake structures

(CWIS) reflect the best technology avai lable (BTA) for minimizing environmental

impacts due to the impingement of fish and shellfish on intake structures and the

entrainment of eggs and la rvae through cooling water systems. The Environmental

Protection Agency (EPA) published regulations applicable to existing electric generating

facilities (Phase II facilities ) in the Federal Register on July 9, 2004. These regulations,

codified in the Code of Federal Regulat ions (CFR) Chapter 40 Part 125 Subpart J,

became effective September 7, 2004. On January 25, 2007, the Second U.S. Circuit

Court of Appeals remanded seve ral provisions of the Phase II rule. On July 9, 2007, the

EPA published a Federal Register notice suspe nding all parts of the Phase II regulations

except 40 CFR 125.90(b) [Louisiana Admini strative Code (LAC) 33:IX.4731.B].

CWIS of existing facilities are now regul ated on a case-by-cas e basis using best

professional judgment per LAC 33:IX.4731.B. The suspended Phase II regulations

established performance sta ndards for CWIS of existing electric generating facilities

which withdraw more than 50 million gallons per day (MGD) of surface waters, more

than 25 percent of which is used for cool ing purposes. These performance standards

required an 80 to 95 percent reduction in im pingement mortality and a 60 to 90 percent

reduction in entrainment. The waterbody t ype on which the facili ty is located, the

facility’s capacity utilization rate, and the ma gnitude of the design intake flow relative to

the waterbody flow determined whether a f acility would be required to meet the

performance standards for impingement mort ality only, or both impingement mortality

and entrainment (IM&E). The final rule allo wed these performance standards to be met

through a combination of technology improv ements, operational measures, and/or

restoration measures and provided an option for site-specific performance standards if

economic conditions did not justify the fu ll costs of meeting the standards.

The suspended Phase II regulation required that each affected facility develop and submit

a Proposal for Information Collection (PIC) to the applicable permitting agency prior to

implementation of data collection ac tivities. The PIC was to include:

 A description of the proposed and/or implem ented technologies, operational

measures, and/or restoration measures that will be evaluated to aid in developing

a compliance strategy to meet the performance standards

 A list and description of any histori cal studies characterizing Impingem ent

Mortality and Entrainment (IM&E) and/or the physical and bi ological conditions

in the vicinity of the CWIS and their relevance to the proposed study

 A summary of any past or ongoing consul tations with regulatory agencies and

other stakeholders that are relevant to the study

 A sampling plan for any new field st udies needed to estima te IM&E.

A PIC was submitted to the Louisiana Departme nt of Environmental Quality (LDEQ) for

review and comment on April 6, 2006 in advan ce of implementing field studies. In a

# 1.1 R EGULATORY 

# A PPLICABILITY



# The Teche Power Station (Teche) is an existin g steam electric generating station with a

CWIS that withdraws greater than 50 MGD of surface water, more than 25 percent of

which is used for cooling purposes. Ther efore, the facility was subject to the

requirements of the Phase II regulations prior to remand. The facility is located on the

Charenton Canal, a tidally influenced body of water, and was subject to both IM&E

performance standards.

Teche currently operates under a Louisiana Pollutant Discharge Elimination System

(LPDES) Permit No. LA0002887 issued by the LD EQ. The permit renewal was received

on December 29, 2004 and became effective February 1, 2005. The permit was modified

on January 7, 2008 to reflect the Second U.S. Circuit Court of A ppeals ruling. The

modified permit includes a schedule for ini tiating compliance with Section 316(b) Phase

II rule requirements of the Clean Water Ac t and applicable St ate regulations.



# 1.2 P URPOSE



# The purpose of this document is to satisfy compliance requirements in accordance with

the modified LPDES permit for the Teche Power Plant. The permit requires that the

following information be submitted within four years from the original effective data of

the LPDES permit:

 Source water physical data

 Cooling water intake structure data

 Cooling water system data

 Source water biological characterization data

 IM&E characterization assessment

# 2.0 FACILITY DESCRIPTION

The Teche Power Station is owned and opera ted by Cleco Corporation. The facility

consists of three steam electric generating units, with a total generation capacity of 477

megawatts (MW). The following is a desc ription of the facility and the source

waterbody. A description of the design and operation of the CWIS and the rate of

withdrawal of cooling wate r relative to the source wa terbody is also included.



# 2.1 F ACILITY 

# L OCATION



# The Teche Facility is located in St. Mary Parish adjacent to the town of Baldwin,

Louisiana at Latitude 29 o 

# 49’ 21” N, Longitude 91 o 

# 32’ 35” W, as shown on Figure 2-1.

All three units utilize once-through cooling water systems. Cooling water is withdrawn

through CWIS located on the western banks of the Charenton Canal (Subsegment number

060601). The cooling water discharge system fo r Units 1 and 2 is located approximately

540 feet downstream of its CWIS and the co oling water discharge system for Unit 3 is

located approximately 1,620 feet downstream of its CWIS (Figure 2-2).



# 2.2 S OURCE 

# W ATERBODY 

# D ESCRIPTION



# The Charenton Canal is located in the lower portion of the Vermilion-Teche River Basin

as shown on Figure 2-1. This sub-segment is in a coastal area that is tidally influenced.

Water in the Charenton Canal, during low flows, comes from Lake Fausse Pointe, the

western portion of Bayou Teche and the eastern portion of Ba you Teche. Most of the

flow in the eastern portion of Bayou Teche is water from the Atchafalaya basin that flows

into the Wax Lake Outlet and then flows westward through the West Calumet floodgates

toward the Charenton Canal. The Charent on Canal drains into West Cote Blanche Bay,

which is connected to the Gulf of Mexico by East Cote Blanche Ba y. During high flow

conditions, water flows westward from the Atch afalaya River into th e Gulf Intracoastal

Waterway, which crosses the Charenton Canal.



# 2.2.1 Physical Characteristics

The Charenton Canal is approximately 220 feet wide in front of Un its 1 and 2 CWIS and

approximately 235 feet wide in front of Unit 3, with an average depth of approximately

30 feet (Figure 2-2). Water le vels in the canal range from El. – 13.5 inches at low water

conditions to El. + 2.5 inches at high water conditions.



# 2.2.2 Water Quality

Conductivity data taken from June 1998 to December 1998 from the LDEQ water quality

station 0674 on the Charenton Canal south of Baldwin, Louisiana corresponds to an

average salinity of approximately 0.2 parts per thousand (ppt). This meets the definition

LPDES 316b submit t al_final.doc 

# 2-1 January 2009

# for a tidal river or stream (salinity is less than or equal to 0.5 ppt). Conductivity data

from two locations on the Charenton Cana l obtained on September 19, 2000 was also

available from FTN’s Synoptic Survey of th e Mermentau/Vermilion-Teche Basins. This

data corresponds to salinity concentrations of approximately 1 and 2 ppt and meets the

definition for an estuary (salinity is greater than 0.5 ppt and typically less than 30 ppt).

Therefore, the Charenton Canal in the vicinity of the Teche facility may be classified as

either a tidal river or an estuary, based upon th e relative influence of freshwater inflow

and tide stage.

Over a 12 month period (June 2006 – May 2007) wa ter quality data was collected for the

316b Phase II Impingement Mortality and Entr ainment Characterization at the Unit 3

CWIS: Mean DO concentration was 6.8 millig rams per liter (mg/L) (range 1.3 – 11.3

mg/L), mean temperature was 73.0 o 

# Fahrenheit ( o 

# F) (range 48.3 – 92.1 o 

# F), mean salinity

was 0.19 grams per liter (g/L) (range 0.01 – 1.68 g/L), and mean pH was 7.78 (7.13 –

9.34). The water quality data that was coll ected may be found in Table 9-1 in the

Fish/Shellfish Impingement and Entrainment Characterization Study (Attachment A).



# 2.2.3 Existing Habitat

The Cleco Teche Power Station’s CWIS are located on the Charenton Drainage and

Navigation Canal in the Vermilion-Teche River Basin, Baldwin, St. Mary Parish,

Louisiana. There is one CWIS for Units 1 and 2 and one CWIS for Unit 3. The intake

for Unit 3 consists of a sheet pile flume on the shoreline: a constructed intake bay is

located between the screens and the canal. Th e front face of the plume has four openings

located below normal water levels of the canal. Water intake for Units 1 and 2 is

withdrawn from the canal through an inlet ch annel and gated structure approximately 500

feet downstream of Unit 3.

The following habitat characterization for th e Charenton Canal applies to both CWIS

given the proximity of the two structures and consistent morphology. The Charenton

Canal is comprised of eutroph ic tidal waters characterized by continuous, bidirectional

flow based upon response to the moon. The manm ade canal is approxim ately six miles in

length from the headwaters discharging fr om Bayou Teche to the confluence of West

Cote Blanche Bay. This canal provides a path way for barge traffic between the two water

bodies. It has a shallow bank stru cture with a strip of ripari an forested land on both sides

of the canal. In the vicinity of the study area, the substrate c onsists of a m ud (silt, loam

and clay) with a relatively flat stream bottom. The canal has a uniform depth of

approximately 30 feet. The stream bank is st able with no erosion slips and is covered

completely with different types of trees and shrubs. The land use for the surrounding area

is primarily agriculture with some light industrial and urban land. Further south the land

use is wetland forest. The elevation of the study area is approximately 2 feet above mean

sea level. The property is relatively flat . In the general ar ea, the topography slopes

south-southwest.

# 2.2.4 Mean Annual Flow

The Charenton Canal exhibits both negative and positive flow as indicated at the U.S.

Geological Survey (USGS) Station 07385790 at Ba ldwin, Louisiana. Flow reversals are

common during low river flow conditions. A revi ew of the daily flow data at the USGS

station for the period of October 2001 to Se ptember 30, 2002 revealed that 106 values out

of 362 were negative. The remaining values were positive indicating that flow is

predominantly towards the gulf. The daily mean stream flow values range from positive

(toward the gulf) 8,390 cubic feet per sec ond (cfs) to negative (toward Bayou Teche)

4,820 cfs. The annual mean flow based on this data is 1840 cfs. Critical flow is 989.4

cfs and the harmonic mean flow is 2968.2 cfs (LDEQ, 2004). The average tidal influence

is approximately 2 inches (LDEQ, 2004).

# D ESIGN



# The Teche facility operates two separate a nd distinct CWIS; one for Units 1 and 2, and

one for Unit 3. The following is a descrip tion of the design and operations of each

CWIS. Table 2-1 is a summary of the cooli ng water intake design for Units 1 and 2 and

Unit 3. A water balance diagram for bot h CWIS may be found on Figure 2-3.



# 2.3.1 Unit 1& 2 CWIS

Cooling water for Units 1 and 2 is withdraw n from the Charenton Canal through an inlet

channel and gate structure located at Latit ude 29° 49’ 20”N, Longitude 91° 32’ 35”W.

The intake channel culminates at the cooling water screen and pump cr ib house. The crib

house contains a single traveli ng water screen, four circula ting water pumps, four service

water pumps, and one screen wash pump. (F igure 2-4). The combined design flow rate

for the Units 1 and 2 CWIS is 51,200 gallons per minute (gpm) (74 MGD), which is

approximately 6 percent of the mean annual fl ow of the Charenton Canal. The area of

influence for the CWIS for Units 1 and 2 is a ssumed to be the full width of the Charenton

Canal. The screen and pump structure sits back from the Charenton Canal and has

provisions for two traveling water screens; however, onl y one traveling screen is

currently installed and operati ng. The screen is of standard design, with 3/8-inch mesh.

All flow entering the screen and pump structur e is screened by the si ngle installed screen.

The current screen has no provisions for handl ing fish and returning them to the canal

and there are no lateral fish passages in the screen structure to allow fish to escape. The

existing approach velocity to the traveling scr een at normal water le vels for Units 1 and 2

is calculated to be 0.24 feet per second (fps). At extreme low water level, the approach

velocity is 0.40 fps. The exis ting through screen velocity at normal water levels for Units

1 and 2 is 0.92 fps. At extreme low water le vel, the through veloc ity is 0.76 fps. The

CWIS for Units 1 and 2 are peaking units and operate as needed to meet energy demands,

usually only for a few hours. During the IM&E Study, the CWIS for Units 1 and 2

operated 47 days out of the year from May 1, 2006 to May 1, 2007 for a total of 124

hours.

# 2.3.2 Unit 3 CWIS

The Unit 3 CWIS consists of a sheet pile fl ume and a screen and pump structure located

at Latitude 29° 49’ 22”N, Longitude 91° 32’ 32”W. The pump structure contains two

traveling water screens and circulating wate r, service water and screen wash pumps.

Water from the Charenton Canal enters th e Unit 3 CWIS though four openings in the

front face of the flume, which are located below normal water levels. Water passes

through the flume to the screen and pump struct ure (Figure 2-5). The design flow rate for

the Unit 3 CWIS is 157,500 gpm (227 MGD), which is approxi mately 16 percent of the

mean annual flow of the Charenton Canal. Th e area of influence for the CWIS for Unit 3

is assumed to be the full width of the Char enton Canal. Circulating water flows through

intake flumes into intake bays and through traveling water screens before entering the

circulating water pumps. The traveling wate r screens are of sta ndard design, with 3/8-

inch mesh and no provisions for removing and returning fish to the Charenton Canal. As

with Units 1 and 2, the traveling water screen is set back from the shoreline and there are

no lateral fish passages. The existing approach velocity to the traveling screens at normal

water levels for Unit 3 is calculated to be 0.72 fps. At extreme low water level, the

approach velocity is 1.04 fps. The existing th rough screen velocity at normal water levels

for unit 3 is 0.72 fps. At extr eme low water level, the throu gh velocity is 1.04 fps. The

CWIS for Unit 3 operates 24 hours per day and 365 days per year, except during

maintenance shutdowns. During the IM&E St udy, the CWIS for Unit 3 operated for 338

days during the year from May 1, 2006 to May 1, 2007 for a total of 7,670 hours.



# 2.4 C OOLING 

# W ATER 

# S YSTEM



# The Teche facility utilizes a once-through cooling water system. Cooling water is

withdrawn through CWIS located on the we stern banks of the Charenton Canal

(subsegment 060601). Design intake rate fo r this plant is 182,600 gpm. There are two

CWIS; one for Units 1 and 2 and one for Un it 3. Circulating wa ter flows through an

intake flume into intake bays and through tr aveling water screens before entering the

circulating water pumps. The cooling wate r system operates 365 days of the year.

The Teche Units 1 and 2 are peaking units and are each normally operated with one of

two available circulating water pumps operating. During the summer months, a

combination of one and two-pumps operating is typical. Unit 3 operates as a base loaded

unit. It operates with one of two availabl e circulating water pumps during the colder

months of November, December, January and Fe bruary. During the re st of the year it

typically operates with two pumps or a comb ination of one and two pumps. The cooling

water system uses 64.02 percent of the design intake flow.

and are based upon operational data from 2000 to 2005.

# 3.0 HISTORICAL INFORMATION

The following is a discussion of historical st udies that have been conducted to assess

CWIS IM&E, and to characterize the physical and biological conditions of the waterbody

in the vicinity of the CWIS. These studies provide information regarding the species

potentially susceptible to IM&E. An IM &E Characterization Study was conducted from

June 2006 to May 2007 to collect updated inform ation to characterize current levels of

IM&E at the facility and determine the calculation baseline against which compliance

with performance standards will be measured. A summary of the findi ngs is described in

Section 4.0 below.

# (1970’ S 

# )

From 1971 to 1973, Gulf South Research Institu te (GSRI) conducted an investigation of

the ecological condition of the Charenton Ca nal for Cleco. The full report identifying

specific methods, data collected, statistical analyses, investig ation results and conclusions

is not available. However, a summary of the first two years of the investigation was

presented to the Louisiana Stream Contro l Commission in a public hearing on June 28,

1973. The following information was obtained from a transcript of th e public hearing.

The investigation was designed to sample nekton, phytoplankton, and benthic organisms

from several locations to dete rmine the ecological condition of the Charenton Canal. To

compare the ecological condition near the Tech e Facility with that of the surrounding

environment, sampling occurred near the Tech e Facility, two miles from the Station, and

4.5 miles from the Station on the Charenton Ca nal. Nektonic organisms were collected

with otter and surface trawls . Phytoplankton was collected and identified from water

samples and benthic organisms were collected with a Peterson dredge. Otter trawls

samples showed no significant difference in the nekton community between the sampling

locations. Surface trawls collected fish from heated waters (assuming this refers to

discharge waters) during the periods of elevated temperatures, from 33° Celsius (°C) to

42°C, however the testimony states that during visual observation fish typically moved

away from heated waters. The results fr om benthic sampling were not completely

analyzed at the time of testimony, but appear ed to show no significant difference between

sampling locations. Phytoplankton sampling al so showed no significant difference in the

phytoplankton community between sampling locatio ns. It was noted that a radioactive

C 14 

# technique showed a significant reduction in phytoplankton producti vity entrained in

the cooling water during summer with periods of elevated water temperature from 37°C

to 45oC. The reduction in phytoplankton productivity appeared to be compensated for in

the reproductive potential of the phytoplankton community because no overall significant

difference between sampling locations was identified.

The study was summarized by the following, “The re are localized disturbances in the

biology of the area but the overall population ap pears to be healthy. ” The limitations of

LPDES 316b submit t al_final.doc 

# 3-1 January 2009

# the information given in the testimony should be noted. It would be inappropriate to

compare the limited information provided in th e testimony to future studies because no

information was provided regarding the fina l conclusions of the three year study,

sampling frequencies, methods, or the parame ters tested to assess ecological condition

(e.g., species composition, abundance, species ri chness, diversity, biomass, catch per unit

effort).

# (1986

– 2004)

The Louisiana Department of Wildlife and Fisheries (LDWF) regularly collects

ichthyofauna data with a variety of sampli ng methods throughout the state. Data has

been requested from the LDWF sampling stati ons in the vicinity of the Teche Facility

that would be representative of the ichthyof aunal communities likely to be found at the

facility. Data were collected from 1986 to 2004 in monthly samples from two locations

in the Vermilion-Teche watershed. Stumpy Ba you, Station 648 in the LDWF database, is

located northeast of Cypremort Point and drains into Vermilion Bay (Figure 3-1). Station

419 in the LDWF database is located off of the northeast point of Marsh Island, in West

and East Cote Blanche Bays (F igure 3-1). The Teche facility is located on the Charenton

Canal which receives water from both Ba you Teche and West Cote Blanche Bay,

depending on tide, river stage, and wind direction. Bayou Teche typically has a

freshwater to brackish signature whereas We st Cote Blanche has brackish to marine

signature. The LDWF does not collect data from the Charenton Canal specifically,

however there is a direct c onnection between Charenton Canal and West Cote Blanche

Bay. Samples collected at Stumpy Bayou a nd the northeast point of Marsh Island is

representative of the taxa that would be exp ected at the Teche Facility from the estuarine

influence.

Sampling methods at the Station 419 and Stat ion 648 were not consis tent. Samples from

Station 419, the northeast point of Marsh Islan d, were collected with a 16-foot flat otter

trawl in 10 minute trawls. Samples at Sta tion 648, Stumpy Bayou, were collected with a

50-foot seine with 0.25-inch delta mesh. Bo th of these sampling methods are commonly

used in estuarine environments where large areas are surveyed. As with any sampling

method, trawls and seines are biased. They underestimate the largest and smallest

organisms found in the environment sampled. However, the data collected does represent

general species composition for the area of interest (Tables 3-1 and 3-2).

Species composition, abundance, and total catch by mont h from 1986 to 2004 were

examined from Station 419 and Station 648. Data from 2001 to 2003 were summarized

for monthly species abundance (Figures 3-2 through 3-12) and total monthly catch. The

most abundant species ( ≥ 50 individuals/collection) fr om Station 419 were: bay

anchovy ( Anchoa mitchilli ), Atlantic croaker ( Micropogonias undulatus ), brown shrimp

( Farfantepenaeus aztecus ), sand seatrout ( Cynoscion arenarius ), blue crab ( Callinectes

sapidus ), and white shrimp ( Litopenaeus setiferus ). The most abundant species ( ≥ 50

individuals/collection) from Station 648 were: bay anchovy ( Anchoa mitchilli ), Atlantic

croaker ( Micropogonias undulatus ), Gulf menhaden ( Brevoortia patronus ), grass shrimp

# ( Palaemonetes spp.), and striped mullet ( Mugil cephalus ). Annual trends in total catch at

Station 419 indicate that total catch was generally greatest in the summer and fall (Figure

3-13). Total catch at Station 648 was gene rally greatest in the spring (Figure 3-14).

The LDWF also regularly samples ichthyofauna at various locations within Lake Fausse

Point (Figure 3-1). Waters from Lake Fausse Point flow into Bayou Teche and therefore

have the potential to influence the ichthyofauna of Charenton Canal. Lake Fausse Point

ichthyofauna data were colle cted with numerous sampling methods: 1) rotenone, 2) hoop

nets, 3) gill nets, 4) seines, and 5) electrofishing. So me sampling methods target

particular species and therefore do not give a representative sa mple of all taxa present in

the lake. However, in combining taxa co llected from all sampling methods, a fairly

comprehensive list can be compiled (Table 3-3). The LDWF sampling schedule for Lake

Fausse Point is not consistent in samp ling methods or throughout the year. Some

sampling methods were used seasonally while others were completed annually. Although

it is apparent from the data that seasonal variation in catch is lower in lakes than in

estuaries, predictions of seasonal abundan ce can not be made from these data.

The data collected by the LDWF can be used to predict the composition of species that

might be collected during impingement and entrainment sampling at the Teche facility.

However, since sampling methods were not consistent, relative abundance of species

expected to be impinged and en trained cannot be predicted.

# Certain animal species are protected in Louisiana under the Endangered Species Act

(ESA) of 1973 and Louisiana state regulations. These species are of particular concern

for 316(b) compliance because the EPA Phase II Rule requires the identification of all

threatened, endangered, and other protected species that might be susceptible to

impingement and entrainment at CWIS. A review of the United States Fish and Wildlife

Service (USFWS) and the LDWF Natural Heri tage Program threatened and endangered

species databases for St. Mary Parish, Louisiana was conducted (Table 3-4). The species

listed are identified as having th e potential to exist within aquatic habitats throughout St.

Mary Parish. However, no sightings data have been reviewed. Parish threatened and

endangered species lists are created based on sightings data and/or the potential for

suitable habitat to exist within a parish. Data requests were submitted to National

Oceanic and Atmospheric Administration (NOAA), USFWS, and the Louisiana Natural

Heritage Program for specific sightings data for any of the protected species in the

vicinity of the Charenton Canal. The USFW S responded in a letter to the data request

and follow-up phone conversations (personal communication, Angela Culpepper). Their

database does not include sightings data for any of the aquatic protected species within

one mile of the Charenton Canal. The NOAA Fisheries office in St. Petersburg, Florida

is responsible for aquatic marine threaten ed and endangered species in the Gulf of

Mexico, i.e., sea turtles. They indicated (personal communication, Eric Hawk) that no

specific sightings data for any of the protected sea turtles in the vicinity of the Charenton

# 4.0 FISH/SHELLFISH IMPINGEMENT AND

ENTRAINMENT CHARACTERIZATION STUDY

REPORT

A fish and shellfish IM&E Characterization Study was performed in the Charenton Canal

at the Teche Power Station located in Baldwin in Saint Mary Parish, Louisiana. Teche

Power Station utilizes a once- through cooling water system consisting of three (Units 1,

2, and 3) oil and natural gas- fired generating units with a total capacity of 430 MW.

Only Unit 3 was sampled for IM&E during the period of this study. IM&E results from

Unit 3 are used to estimate IM&E for Un its 1 and 2 based on pr oportional design flowrelated extrapolations, to give an IM&E characteri zation of the entire station.

This final report (Attachment A) includes re sults from 12 months of impingement and

entrainment sampling data, from June 2006 to May 2007. A brief summary of the results

may be found below:

 A total of 942 eggs, 203 larvae, a nd 12,828 juvenile fish and shellfish

were collected from 117 entrainm ent samples during 12 months of

sampling at Teche Power Station. All ichthyoplankton combined

represented 28 species belonging to 21 families.

 A total of 45,352 individual fish and shellfish were collected from 117

impingement samples during 12 mont hs of sampling at Teche Power

Station. All impinged fish and shellf ish combined represented 52 species,

belonging to 32 families.

 There were an estimated 196.7 million e ggs/larvae/juveniles entrained at

the Teche Power Station from J une 2006 to May 2007, under actual

operating flow conditions. Howe ver, as many as 369.6 million

eggs/larvae/juveniles could have been entrained in this same period if the

station had operated at full design capacity flows.

 There were an estimated 417,722 juve niles/adults impinged at Teche

Power Station from June 2006 to May 2007, under actual operating flow

conditions. However, as many as 765,720 juveniles/adults could have

been impinged in this same period if the station had operated at full design

capacity flows.

EXPLANATION OF RANKING CATEGORIES EMPLOY ED BY NATURAL HERITAGE PROGRAMS

NATIONWIDE

Each element is assigned a single global rank as well as a state rank for each state in which it occurs. Global ranking

is done under the guidance of NatureServe, Arlington, VA. State ranks are assigned by e ach state’s Natural Heritage

Program, thus a rank for a particular el ement may vary considerably from state to state. Federal ranks are designated

by the U.S. Fish & Wildlife Service under the pr ovisions of the Endangered Species Act of 1973.

FEDERAL RANKS :

LE = Listed Endangered

LT = Listed Threatened

STATE RANK :

S3 = rare and local throughout the state or found locally (e ven abundantly at some of its locations) in a restricted

region of the state, or because of other factors maki ng it vulnerable to extirpation (21 to 100 known extant

populations)

GLOBAL RANKS :

G4 = apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery (100 to

1000 known extant populations)

# Report Summary ________________________________________________

A fish and shellfish Impingeme nt Mortality and Entrainment Characterization (IM&E) Study

was performed in the Charenton Canal at the Teche Power Station located in Baldwin in Saint

Mary Parish, Louisiana. Teche Power Station is an existing steam electric generating facility that

is operated by Cleco Power LLC (C leco) with a once through cool ing system for existing Units

1, 2, and 3.

This final report includes results from 12 months of impingement and entrainment sampling data,

from June 2006 to May 2007.

• A total of 942 eggs, 203 larvae, and 12,828 juvenile fish and shellfish were

collected from 117 entrainment samples during 12 months of sampling at Teche

Power Station. All ichthyoplankton comb ined represented 28 species belonging

to 21 families.

• All of the entrained species in the egg stag e could not be identified to a particular

species or group.

• The most abundant entrained species in the larval stage were Decapoda

(unidentified crab & shrimp ), unidentified fish remains, and Gobiidae (gobies)

which together accounted for approximat ely 39%, 26%, and 24% of the entrained

larvae.

• The most abundant entrained species in the juvenile stage were bay anchovy and

mysid shrimp, which accounted for approximately 32% and 56% of the

entrainment larvae, respectively.

• A total of 45,352 individual fish and shellfish were collected from 117

impingement samples during 12 months of sampling at Teche Power Station. All

impinged fish and shellfish combined re presented 52 species, belonging to 32

families. Atlantic croaker was the most abundant species and accounted for

approximately 33% of the total numbe r of fish and shellfish collected,

respectively. Other abundant species im pinged during the 12 months of sampling

include unidentified shrimp remains (14 %), brown shrimp (13%), Ohio river

shrimp (10%), blue crab (9%), and ba y anchovy (8%). Shellfish accounted for

46% of all impinged fish and shellfish.

• Weekly impingement rate s averaged 14,726 fish per week over the entire 12-

month sampling period. However, this av erage was strongly influenced by high

abundances of Atlantic croake r in June and July 2006.

• There were an estimated 196.7 million eg gs/larvae/juveniles entrained at the

Teche Power Station from June 2006 to May 2007, under actual operating flow

conditions. However, as many as 369.6 m illion eggs/larvae/juveniles could have

been entrained in this same period if the station had operated at full design

capacity flows.

# 1.0 Introduction

Shaw Environmental, Inc (Shaw) and Provide nce Engineering and Environmental Group LLC

(Providence) in conjunction with Louisiana State University (LSU) Agricultural Center, School

of Renewable Natural Resources (SRNR) con ducted a 12-month Impingement Mortality and

Entrainment (IM&E) sampling program at the Cl eco Teche LLC (Cleco) Teche Power Station

located in St. Mary Parish, Louisiana, from June 2006 to May 2007. This sampling program was

conducted in accordance with the now suspende d 316(b) Phase II Rule to satisfy data

requirements necessary to character ize the existing levels of IM&E at this facility, as described

in the Proposal for Information Collection (P IC) submitted to Louisiana Department of

Environmental Quality (LDEQ) on April 6, 2006. The purpose of this monitoring was to

evaluate the occurrence and a bundance of species impinged and en trained in the cooling water

intakes at Teche Power Station.

Teche Power Station utilizes a onc e-through cooling water system c onsisting of three (Units 1, 2,

and 3) oil and natural gas-fired generating units with a total capacity of 430 megawatts (MW).

Only Unit 3 was sampled for IM&E during the pe riod of this study. IM&E results from Unit 3

are used in this repor t to estimate IM&E for Units 1 a nd 2 based on proporti onal design flowrelated extrapolations, to give an IM&E charac terization of the entire station. The daily flow

rates for Unit 3 for June 2006 through May 2007 are presented on Figure 1-1

.

There are two cooling water intake structures (CWIS); one for Units 1 and 2, and one for Unit 3.

The existing intake structures for the Units 1 and 2 and Unit 3 cooling water system are each

equipped with two sets of standard traveling wate r screens (3/8-mesh) designed to prevent debris

from entering the power plant with no fish and shellfish protection features. A high pressure

spray header washes debris and organisms off th e screens and into the re turn trough leading back

to the Charenton Canal. Impinged fish and sh ellfish were collected from this return trough.

Entrained fish and shellfish were sampled from a bypass tap located on the main cooling water

intake pipe, behind the Unit 3 circulating wate r pump. Each of the monthly, 24-hour sampling

events was broken into three, 8 hour blocks.

The original goal of this study was to provide the data necessa ry to characte rize the baseline

IM&E impacts and to propose reductions in ac cordance with the Phase II 316(b) regulations.

The Phase II Rule has been formally suspende d and Cleco’s Louisiana Pollutant Discharge

Elimination System (LPDES) permit has been m odified to remove the requirement to submit a

CDS.

However, this IM&E characteri zation study does provide the most current information to assess

the facility’s IM&E impacts. These impacts can be compared to the calculation baseline

# 2.0 Sampling & Data Collection Methods

All impingement and entrainment sampling follo wed the monthly schedule described in the

Standard Operating Plan (SOP) located in Appendix A

.



# 2.1 Impingement Sampling

Impingement sampling was conducted by collecting al l fish and shellfish washed off both of the

Unit 3 traveling water screens and into the coll ection basket for a period of 24 hours (i.e. one

sample event). Each impingement sampling ev ent covered an entire 24 -hour period, which was

divided into three 8-hour sampling blocks ( Table 2-1 ). Immediately prior to the sampling event

the traveling screens were rotated for at least two continuous cycles to ensure that all previously

accumulated organisms/debris were cleared. A custom-fitted 1⁄4-inch nylon knotless mesh net

liner was set inside the metal debris basket; th is allowed for organisms to remain in optimal

condition during the collection period. The mesh net liner conservatively retained all organisms

impinged on the 3⁄8 -inch square mesh of the tr aveling water screens. The metal debris basket was

mounted on a pulley system operated by a hand-crank. This set-up allowed for the basket to be

lowered into the screenwash discharge fish-retu rn during sampling and hoisted up during sample

retrieval. All fish and shellfish collected were measured to the nearest mm, and identified to the

lowest practical taxon level usi ng standard taxonomic keys. Overall condition (live, dead,

head/body only), was also assessed on each collect ed specimen. Field not es included start/end

times, number of screens operating, tide stage and direction, and other additional information

related to general sampling conditions.

B – day 10:00 –18:00 15:30 – 18:00

C – night 18:00 – 02:00 23:30 – 02:00



# Each 8-hour impingement sample was processed immediately on-site. Sample processing

involved separating fish and shel lfish from debris and other non-target organisms (reptiles,

amphibians, and other non-target invertebrates). Impinged fish a nd shellfish were identified to

the lowest possible taxon (usually species) and count ed. Fish and shellfish were measured to the

nearest 1-millimeter (mm) total length (TL). If more than 100 individuals of any species were

# N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Te che Final IM&E 316b Report4.doc January 2009



# 2-2 

# observed, then length measurements were obtain ed for a representative sub-sample of 25

individuals.

Total impingement density during each week was used to evaluate seasonal occurrence patterns

by species. Diel abundance patter ns were also evaluated by comparing the average density

among the three distinct impingement sampling bl ocks. Seasonal abundance patterns we re also

evaluated in a similar manner. To obtain values for non-sampled weeks, the average

impingement for the closest week prior to, and af ter, that particular non-sampled week was used.

In most cases, this average value was used for multiple non-sampled weeks between sample

weeks. For example, if total impingement fo r sample week A and sample week D was 100,000

fish and 200,000 fish, respectively, then the average value between weeks A and D (150,000

fish) was used to obtain values for the non-sampled weeks B and C. If the interval between

sample events was four weeks, these non-sampled weeks are identified as such (marked in red)

in Appendix B

.



# 2.2 Entrainment Sampling

Traditional towed plankton net entrainment sampli ng techniques require the assumption that the

location of sampling is representative of the pl ankton abundance entrained in the circulating

water flows. Assumptions regarding the represen tativeness of the sample were not needed for

the entrainment data, since collections were made directly from the cooling water intake. The

entrainment samples used a digital pipe-mounted flow meter to measure entrainment sample

flows through the net. The entrainment sampling did not require a flow meter outside the net

since the net was not towed through the water column.

A total of three entrainment samples were collected during each 24-hour sample event. The

number of fish and shellfish eggs and larvae pres ent in each entrainment sample were converted

to density estimates (number of fish and shellfish eggs/larvae per 100 cubic meters {m 3 

# } of

water). Average weekly entrainment density was used to evaluate seasonal occurrence patterns

by species. Diel abund ance patterns were also evaluate d by comparing the average weekly

density among the three distinct entrainment sampling blocks.

An innovative sampling method was used to collect fish and shellfish entrainment samples from

Unit 3. A ball-valve actuated tap on the circulat ing water system piping situated downstream of

Unit 3’s circulating pumps allowe d for direct sampling of the fish and shellfish that were

entrained within the plant’s cooling water flow. The 4-inch bypass pipe and associated valves

supplied a constant stream of intake cooling wa ter to an energy dissipation tank where a standard

0.5-meter (m) diameter plankt on net (0.505 mm mesh) was used to collect the entrained

organisms ( Figure 2-1 ). During entrainment sampling, the net ring was held in place under the

pipe while the net floate d freely in the tank. A flow meter (Greyline Instruments Area Velocity

Flow meter with velocity/level sensor QZO2L Model-AVFM-II-C1A2A1A4A with a flow

# totalizer) was used to measure the volume of intake water sampled, with an instantaneous

velocity accuracy of ±2%, according to the ma nufacturer’s specifications. Each entrainment

sample was collected from approximately 100 m 3 

# of intake water and the collection efficiencies

for entrainment samples were always 100%. The minimum duration of sampling (time needed to

obtain more than 100 m 3 

# ) was consistent, but somewhat depende nt on cooling water intake flow.

Sampling flows into and out of the sampling tank c ould also be controlled by manually adjusting

the valves to achieve the desired flow rate. Sample volume collected was typically between 100

to 110 m 3 

# , regardless of sample duration. Based on these conditions, there is no reason to

suspect that any extrusion of organisms thr ough the mesh occurred with this entrainment

sampling method.

# 3.0 Field Processing & Identification

All impingement samples were collected and id entified by Providence with the assistance of

fisheries biologists from LSU SR NR on-site at Teche Power Station. All impingement samples

were processed in accordance with Shaw/Pro vidence/LSU’s quality assurance and quality

control (QA/QC) specifications, as described in the SOP document for this project (see

Appendix A ). Field guides/taxonomic keys were used to identify fish and shellfish down to the

lowest practical taxon. A count, a measurement of each individua l’s total length (mm), and a

note of the condition of each individual was recorded on the information data sheet for each

sample event.

The condition of the fish collected was also obse rved during the study. Individuals that were

measured for TL were also inspected for screen ma rks, injury, etc. Individuals were categorized

as live (L) or dead (D) and fiel d codes were used to qualitativel y record any injury/damage status

SOP ( Table 2-2 ).

# 3.1 Laboratory Processing of Entrainment Samples

All entrainment samples were preserved with 10% buffered formalin and stored in a cooler onsite. Preserved samples were shipped via courie r to LSU SRNR Laboratory in Baton Rouge. All

entrainment samples were processed in accordance with Shaw/Providence/LSU’s quality

assurance and quality control (QA/ QC) specifications, as describe d in the SOP document for this

project. A minimum criterion of 200 eggs or 100 larvae was used to invoke sub-sampling

procedures. However, for this study, the entire contents for al l entrainment samples were fully

# N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Te che Final IM&E 316b Report4.doc January 2009



# 3-2 

# examined, identified, and enumerat ed without splitting. Entrained fi sh and shellfish eggs, larvae,

and juveniles were identified to the lowest practical (distinguishable) taxonomic unit and

enumerated. Any juvenile fish and shellfis h observed in the ichthyoplankton samples were

included with the counts, but de signated as young-of-year (YOY), or juvenile. The total number

of ichthyoplankton in each sample of a known filtered volume wa s used to calculate volumebased ichthyoplankton densities (i.e. th e number of eggs or larvae per 100 m 3 

# ).



# 3.2 Quality Assurance & Quality Control

The goal of the QA/QC Plan was to ensure that work performance and resulting data/reports

were of the highest quality and provided in a co st-effective, scientifically defensible, and timely

manner. The reliability, accuracy, and truth of results reported were monitored through QA

procedures and maintained a required le vel of reliability through QC procedures.

The sampling coordinator trained all field personnel and performe d an on-site QA inspection of

field procedures during the fi rst sample event. For the impingement sampling, the QA/QC

inspection program was conducted in the field with the assistance of LSU personnel. All of the

samples that were collected and processed (i .e. sorting, counting, and identification) were

checked by another project biolog ist on-site. A more detailed description of the specific QA/QC

plan is included in the project SOP.



# 3.3 Data Analysis

The raw number of fish and shellfish present in each impingement and entrainment sample were

converted to rates or density estimates (number of impinged or entrained fish and shellfish per

unit volume). Average weekly impingement or entrainment density was used to evaluate

seasonal occurrence patterns by sp ecies. Night and day abundance patterns were also evaluated

by comparing the average weekly density (which was estimated by using empirical “as sampled”

data) of the three distinct sample blocks. Seas onal abundance patterns were also evaluated in a

similar manner. For each of the 52 weeks (J une 2006 through May 2007), weekly impingement

and entrainment densities were calculated based on the fish and shellfis h identified during each

sampling event. To obtain impingement and en trainment densities for weeks that were not

sampled, the average density from the closest w eek prior to, and after, that particular nonsampled week was used to determine non-sa mple week values (see Section 1.1).

The total raw numbers of impinged or entrained fish and shellfish collected on the Unit 3 screens

during the 12-month sampling peri od was extrapolated to flow-based estimates for the entire

station (Units 1, 2, and 3). Annual flow-based impingement was estimated for each species by

multiplying the impingement density (number of fish and shellfish per impingement sample

volume) by the total design flow volume of coo ling water for the entire station. Annual flowbased entrainment was also calculated in this manner. The total number of impinged and

# N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Te che Final IM&E 316b Report4.doc January 2009



# 3-3 

# entrained fish and shellfish during the 12-month sampling period were estimated for each species

within a sample block by multiplying the density (number of fish and shellfish per sample

volume) by the total volume of cooling water us ed by the facility during the week, by solving for

X as shown below:

(Number of fish collected during 8- hour block or

100m 3 

# sample)



# = ( X number of estimated fish collected in a week of 8-hour blocks or

100m 3 

# sample)

(Volume of cooling water used during 8-hour block) (Volume of cooling water used during a week of 8- hour blocks)



# It is important to note that the same raw numb er of entrained or impinged individuals do not

result in the same number of flow-based estimate d individuals. The reason for this is that the

entrainment is sampled from a much sma ller proportional volume than impingement.

Entrainment samples were t ypically collected from 100m 3 

# (26,417 gallons) of water during each

8-hour sample block, whereas an impingement sample is collected from 64,320,080 gallons of

water flowing through the Unit-3 screens during each 8-hour sample block. Converting the raw

numbers to densities (number of impinged or entr ained fish and shellfish per unit volume) prior

to extrapolating to annual flows accounts for these differences in sample volumes. For example,

during this study there were 4 i ndividual freshwater drum impinge d during this st udy, resulting

in an estimated 64 freshwater drum when th e raw numbers are extrapolated based on annual

flow. For this same species, only 1 freshwater drum larva wa s collected in the entrainment

samples. However, because of the volume di fferences between impingement and entrainment

sampling methods, this single indi vidual resulted in an estimate d 22,385 freshwater drum when

the raw numbers are extrapolated based on annual flow.

Also, for an estuarine system, such as the Charenton Canal, the number of fish/shellfish eggs &

larvae far exceed the number of juvenile or adu lt stages of fish/shellfish present in the water

column at any given time (with seasonal variability).

Two flow scenarios were evaluated with this IM&E data collected at Teche. Scenario-1 included

only the actual flows from all Un its, while Scenario-2 included the 100% design flows of all

Units. This Scenario-2 assumed continuous full-flow operations du ring the 12-month study

period. Results for both scenarios are outlined in Section 6.1.



# 3.4 Threatened & Endangered Species

Certain animal species are protected in Louisiana under the Endangered Species Act (ESA) of

1973 and Louisiana state regulations. These sp ecies are of particular concern because the

remanded Phase II 316(b) rule required the identifi cation of all threatene d, endangered, and other

protected species that might be susceptible to impingement at the CWIS. The U.S. Fish and

Wildlife Service (USFWS) and the LDWF, Natural Heritage Program threatened and endangered

# species databases for St. Mary Parish, Louisiana we re reviewed. St. Mary Parish has the potential

to contain eight threatened and endangered aquatic species ( Appendix C ). However, there were

no sightings data for this location. Threatened and endangered spec ies lists by pari sh are created

based on sightings data and/or th e potential for suitable habitat to exist within a parish. Data

requests were submitted to National Oceanic and Atmospheric Administration (NOAA),

USFWS, and the Louisiana National Heritage Program for specific sightings data for any of the

protected species in the vicin ity of the Charenton Canal. The USFWS responded to the data

request in a letter and follow- up phone conversations and emails (personal communication with

Angela Culpepper, 11/1/2004 to 11/23/2004). Their da tabase does not include sightings data for

any of the aquatic species within a one mile radius of the Charenton Canal. The Louisiana

National Heritage Program responded to the data request in a letter. Their database does not

include any rare, threatened, or endangered species within one mile of the Charenton Canal. The

NOAA Fisheries office in St. Petersburg, Florida is responsible for aquatic marine threatened

and endangered species in the Gulf of Mexico, i. e., sea turtles. NOAA Fisheries indicated that no

specific sightings data for any of the protected sea turtles in the vicinity of the Charenton Canal

exists (Personal communication w ith Eric Hawk, 11/5/2004).

# All impinged fish and shellfish combined represented 52 species, belonging to 32 families.

Overall, Atlantic croaker was the most abunda nt species and accounted for approximately 33%

of the total number of fish and shellfish coll ected, respectively. The condition of impinged fish

and shellfish was assessed for all measured sp ecimens, according to the criteria described in

Section 2 of this report. Overall, 41% of impinged specimens were dead and 14% were live

upon collection ( Table 4-3 ). Another 45% of impinged or ganisms were not measured, and

therefore the condition was not assessed. Th is proportion of specimens not assessed was

comprised mostly of Atlantic croaker. This species exhibited numbers greater than 100 for

certain sample events, so only representative samp les were measured/ assesse d. It should also be

noted that 100% mortality was assumed for all fish and shellfish impinged on these traveling

screens on an 8-hour rotation schedule withou t any fish protection measures in place.

Overall, of the 45,352 fish/shellfish (dead or live) collected, only 13% e xhibited some type of

damage. The occurrence of headless shrimp was the most common damage observed for

impinged organisms, resulting in the “unidentifie d shrimp” category. The only damage criteria

that occurred was categorized under the “general w ound” criteria (code-6) , with no specific

attributes associated with impingement (screen mark s, etc.). There was also one blue crab (dead)

with “black spot” observed on its shell. However, because the crab was already dead and in poor

condition, the “black spot” observed was most lik ely a result of decomposition, not necessarily

related to the black spot disease pa rasite found in some fish species.N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Teche Final IM&E 316b Report4.docJanuary 20094-5Table 4-3: Assessment of condition for impinged specimens collected, using the criteria described in Section 2.Common NameNOCONDITIONRECORDEDLIVE (nodamage L)LIVE(generalwound L-6)LIVETOTALDEAD (nodamage L)DEAD(blackspot D-4)DEAD(generalwound D-6)DEAD(headless D-9)DEADTOTALAlosa chrysochloris00 003 0 0 03Ameiurus melas03 030 0 0 00Ameiurus natalis00 002 0 0 02Anchoa mitchilli1,09513 0132,373 0 38 02,411Anguilla rostrata02 022 0 0 02Aphredoderus sayanus00 004 0 0 04Aplodinotus grunniens00 004 0 0 04Ariopsis felis05 0593 0 1 094Bagre marinus00 001 0 1 02Bathygobius soporator00 003 0 0 03Brevoortia patronus4421 01291 0 2 0293Callinectes sapidus1,3912,602 02,602230 1 3 0234Cambaridae01 011 0 0 01Citharichthys spilopterus5303 03352 0 1 0353Ctenogobius shufeldti015 01521 0 0 021Cynoscion arenarius454 04876 0 3 0879Decapoda01 010 000Dormitator maculatus062 06222 0 1 023Dorosoma cepedianum00 0041 0 3 044Dorosoma petenense01 01153 0 2 0155Elops saurus00 0015 0 2 017Farfantepenaeus aztecus8014 045,044 0 0 05,044Gambusia affinis00 001 0 0 01Gobiidae00 001 0 0 01Gobioides broussonetii016 01620 0 8 028Gobionellus oceanicus00 0011 0 1 012Gobiosoma bosc00 004 0 0 04N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Teche Final IM&E 316b Report4.docJanuary 20094-6Common NameNOCONDITIONRECORDEDLIVE (nodamage L)LIVE(generalwound L-6)LIVETOTALDEAD (nodamage L)DEAD(blackspot D-4)DEAD(generalwound D-6)DEAD(headless D-9)DEADTOTALIctalurus furcatus024 125100 0 1 0101Ictalurus punctatus06 067 0 4 011Ictiobus cyprinellus20 007 0 2 09Lepomis gulosus02 022 0 0 02Lepomis macrochirus01 0118 0 1 019Lepomis megalotis01 010 0 0 00Lepomis symmetricus00 002 0 0 02Lucania parva00 001 0 0 01Lutjanus griseus00 0022 0 0 022Macrobrachium ohione1,4991,852 01,8521,019 0 4 01,023Membras martinica00 008 0 1 09Menidia beryllina00 0010 0 0 010Micropogonias undulatus14,02913 0131,078 0 6 01,084Morone saxatilis00 001 0 0 01Mugil cephalus01 0115 0 0 015Orconectes hobbsi01 010 0 0 00Orconectes spp.11 010 0 0 00Paralichthys lethostigma011 01187 0 4 091Polyodon spathula00 006 0 0 06Pomoxis annularis00 001 0 0 01Prionotus tribulus00 0013 0 0 013Pylodictis olivaris00 002 0 0 02Rhithropanopeus harrisii029 0293 0 0 03Sciaenops ocellatus00 002 0 0 02Sesarma cinereum00 001 0 0 01Syngnathus scovelli00 003 0 0 03Trinectes maculatus4931,657 01,657282 0 5 0287Uca rapax01 010 0 0 00Uca subcylindrica00 001 0 0 01Unid.

# 4.1.1 Estimated Annual Impingement

A total of 765,720 individual fish and shellfish we re estimated to be impinged at Teche Power

Station for the duration of the 12-month samp ling period. This impingement estimate assumes

100% capacity generation with full design fl ow (253.4 MGD) from Units 1, 2, and 3. Table 4-4

lists the total estimated numbers of fish and shellfish impinged for all species. This scenario

provides the basis for the calculation baseline impinge ment at this facility and will be referred to

as such throughout the document.

Over the entire 12-month sampling period, the av erage estimated design flow impingement was

approximately 14,726 fish and shellfish per week (ranging from 1,876 to 68,165 per week). In

terms of flow, this average impi ngement represents approximately 8.3 fish or shellfish impinged

for every 1 million gallons of cooling water flow.

# 4.1.2 Seasonal & Diel Patterns of Impingement

The average estimated impingement at Teche Power Station was 14,726 fish and shellfish per

week ( Figure 4-1 ) and strongly driven by higher a bundances of Atlantic croaker ( Figure 4-2 ).

The 11-week period from 04 June 2006 to 23 Ju ly 2006 accounted for approximately 36% of the

total impingement for the entire year. The 8-we ek period from 10 Sept 2006 to 29 October 2006

accounted for approximately 36% of the total im pingement for the entire year. The 4-week

period from 06 May 2007 to 27 May 2007 account ed for approximately 11% of the total

impingement for the entire year. During the week of 17 Sept 2006, weekly impingement peaked

at 68,165 fish and shellfish per week. During the sample weeks of 04 June 2006 to 23 July 2006,

weekly total impingement averaged 34,836 fish and shellfish per week and during the sample

weeks of 10 Sept 2006 to 29 October 2006; impinge ment averaged 34,063 fish and shellfish per

week. During the sample weeks of 06 May 2007 to 27 May 2007, impingement averaged 20,356

fish and shellfish per week.

Overall, annual impingement totals were highest during the night (399,186) sampling blocks than

during the morning (184,143) and day (182,391) samp ling blocks. The day and night sampling

periods exhibited similar impingements rates. A quantitative assessment of diel patterns of

impingement from these data however is difficult because the sampling blocks overlap twilight

periods (sunrise/sunset) wh ich strongly influence fish behavi or and abundances throughout a 24-

hour period.

Seasonal variation in ambient water quality conditions may have also influenced the patterns of

impingement observed at Teche. One of the peak impingement periods during July 2006

occurred during a period of extremely lo w dissolved oxygen (D.O.) of 1.3 mg/L (see Figure 9-

2 ). It is likely that this period of low D. O. during the summer may ha ve contributed to high

levels of impingement, particularly for Atlantic croaker, although there is no si te-specific data to

support this correlation. In this scenario, a low D.O. fish kill unrelated to the presence of the

intake structure may have increased the loading of impinged fish that entered the intake. D. O.

levels were improving by mid September and Oc tober when two other peaks in impingement

abundance occurred. However, two distinct peaks in salinity coin cided with increased

impingement during this period (see Figure 9-2 ). Shrimp were the most abundant organism

during these distinct periods of increased salin ity. It is likely that the abundance of shrimp

(brown shrimp, Ohio river shrim p, unidentified shrimp) was related to increased salinity in the

vicinity of Teche Power Stati on during the fall season; a peri od when brown shrimp typically

exhibit movements out of the estuary as sub-adults (R. Harlan, LSU-SRNR personal

communication 11/9/2006). Furthermore, based on this life history information and the timing

of abundance, it is also likely that the majority of the “uniden tified” shrimp (headless) were

brown shrimp which tend to become more easily damaged than Ohio river shrimp (R. Harlan,

# 5.0 Entrainment Results

5.1 Abundance, Density, and Percent Occurrence

A total of 942 eggs, 203 larvae, and 12,828 juven iles were collected from 117 entrainment

samples during the sampling period (6 June 2006 to 22 May 2007). All ichthyoplankton

combined represented 28 species belonging to 21 families ( Table 5-1 ). Eggs that could not be

identified due to ambiguous characteristics or damage were listed as “unidentified.”

The decapod crab/shrimp were the most abundant species in the larval stage, accounting for

approximately 39% of the entrained larvae species

. The most abundant species in the juvenile

stage was the mysid shrimp, comprising 56% of the entrained juvenile species ( Table 5-2 ). All

species represented in the entrainment samples also occurred in the impingement samples with

the exception of banded drum, ( Larimus fasciatus ), mysid/opossum shrimp ( Taphromysis

louisianae ), least killifish ( Heterandria formosa ), fairy shrimp ( Phyllopodous branchiopoda ),

and mantis shrimp ( Squilla empusa ). The absence of these species from the entrainment samples

may be attributed to the physical and hydrological characteristics of the CW IS as well as life

history traits of different species (demersal, pelagic, or adhesive eggs or larval dispersal in the

water column).

# 5.1.1 Estimated Annual Entrainment

A total of 369,594,332 fish and shellfish (eggs, larvae , juveniles) were estimated to be entrained

at Teche Power Station during the duration of the 12-month sampling period (6 June 2006 to 22

May 2007). This entrainment estimate assumes 100% capacity generation w ith full design flow

(253.4 MGD) from Units 1, 2, and 3. Table 5-3 lists the total estimated numbers of fish and

shellfish entrained for all species. This scenario provides the basis for the calculation baseline

entrainment at this facility and will be referred to as such throughout the document.

Weekly total estimated entrainment at Teche Power Station, over the entire 12-month sampling

period, averaged an estimated design flow entr ainment of 7,107,583 fish and shellfish per week

(ranging from 179,083 to 48,262,947 per week).

Note that the following sections discuss entrainment at Teche Po wer Station in terms of these

estimated numbers, compared to the entrainment “as sampled” in earlier sections of this report.Table 5-3: Estimated ANNUAL entrainment by species at Teche Power Station based on full station (calculation baseline)operation, June 2006–May 2007.LIFESTAGE SPECIES/TAXA COMMON NAMETOTALNUMBERCOLLECTEDANNUALESTIMATEDENTRAINMENT(MORNING)ANNUALESTIMATEDENTRAINMENT(DAY)ANNUALESTIMATEDENTRAINMENT(NIGHT)TOTAL ANNUALESTIMATEDENTRAINMENTN:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Teche Final IM&E 316b Report4.docJanuary 20095-5

# 5.1.2 Seasonal & Diel Patterns of Entrainment

Overall entrainment densities were highest durin g fall and spring; specif ically October 2006 and

May 2007. The total combined entrainment in October 2006 and May 2007 accounted for

approximately 52% of the total entrainment for the entire year. Juveniles peaked at

approximately 47.3 million during one week in th e fall, and 41.1 million during one week in the

spring ( Figure 5-1 ). Eggs peaked at approximately 8.4 million during one week in spring only,

while larvae remained largely absent from the intake throughout the year, with only minor

abundances during one week in June (1.1 million) and another week in October (0.9 million).

Seasonal patterns of species abundance patterns we re observed for eggs, larvae and juveniles.

Unidentified mysid shrimp (juvenile) accounted for the majority of the peak in abundance from

October 2006 (67%) to May 2007 (77%) ( Figure 5-2 ).

Figure 5-1: Estimated entrainment rate for eggs , larvae, & juvenile (# of fish/shellfish per

week) at Teche Power Station, June 2006–May 2007.

The most abundant species in the egg stage we re the unidentified eggs , which accounted for

approximately 100% of th e entrained egg species

. Some fish and shellfis h were “unidentified”

due to ambiguous characteristics or damage to the organism. The most abundant species in the

larval stage were the unidentified decapod crabs, which accounted for approximately 39% of the

entrained larvae species

. The most abundant species in the j uvenile stage were mysid shrimp,

which accounted for approximately 56% of the entrained juvenile species.

# 6.0 Entrainment & Impingement Impacts

• The total estimated number of individual fish and shellfish eggs entrained for the

duration of the 12-month sampling period (June 2006 – May 2007) was:

- 15.30 million for actual station flows (Scenario-1)

- 23.47 million for 100% design capacity station flows (Scenario-2)

• The total estimated number of individual fish and shellfish larvae entrained for

the duration of the 12-month sampli ng period (June 2006 – May 2007) was:

- 3.23 million for actual station flows (Scenario-1)

- 5.29 million for 100% design capacity station flows (Scenario-2)

• The total estimated number of individual fish and shellfish juveniles entrained for

the duration of the 12-month sampli ng period (June 2006 – May 2007) was:

- 178.14 million for actual station flows (Scenario-1)

- 340.83 million for 100% design capacity station flows (Scenario-2)

• The total estimated number of individual fish and shellfish ( juvenile, adult )

impinged for the duration of the 12-m onth sampling period (June 2006 – May

2007) was:

- 417,722 for actual station flows (Scenario-1)

- 765,720 for 100% design capacity st ation flows (Scenario-2).

Tables 6-1 and 6-2 list the total estimated numbers of or ganisms entrained and impinged for all

species under both operational flow scenarios. The estimated weekly impingement under both

scenarios of impingement and entr ainment impacts are based on the de nsities of all lifestages of

fish and shellfish collected duri ng the sampling period and actua l flow data (or design flow

capacity) for cooling water used at Teche Power Station. Scenario-1 take s in account all times

during the 12-month sampling period when the fac ility did not draw any cooling water from the

Charenton Canal including scheduled outages, standby periods, and singl e circulating water

pump operations. Scenario-2 assumes 100% design flow operation, as permitted, year-round.N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\Teche Final IM&E 316b Report4.docJanuary 20096-2Table 6-1: Estimated total

# 7.0 IM & E Lights On/ Lights Off Sampling

A sub-study was conducted to evaluate the potential effect of outdoor lighti ng in the vicinity of

the cooling water intake struct ure on IM&E at Teche Power St ation. Comparisons were made

between the “lights-off” treatment group of samples and the “lights-on” control group of

samples. A total of eight 24-hour routine/baseline IM&E samples were collected with the “lights

on” in conjunction with eight 24- hour routine/baseline IM&E samples collected with the “lights

off” ( Table 7-1 ). This study occurred during the last two months (April 2007 and May 2007) of

the 12-month sampling, June 2006 – May 2007.

# 7.1 Entrainment Light/ No Light Analysis

After analyzing all life stages in the combin ed C and A entrainment light/no light sample,

comparable differences were recognizable. Juvenile bay anchovy, gulf menhaden, and gulf

pipefish exhibited the largest increase (based on numeric data) in entrainment abundance during

“no-light” sampling (65%, 62% , and 57%, respectively) ( Appendix D ).



# 7.2 Impingement Light/ No Light Analysis

Bay anchovy and river shrimp exhibited the la rgest decrease (based on numeric data) in

impingement abundance during “no-light” samp ling (37% and 84% respectively). Gulf

menhaden, Atlantic croaker, and hogchoker exhibi ted the largest increase (based on numeric

data) in impingement abundance during “no-light sampling (47% and 84% respectively). A few

other species although small in num ber were found in the in either the “light” or “no-light”

sampling period. Highfin goby, cl own goby, striped bass, freshwat er drum, spotted seatrout,

brown shrimp, golden shiner, fairy shrimp, and spot (often mistak en for Atlantic croaker) were

found only in the “no-light” sampling, whereas bigmouth buffalo, violet goby, rainwater

# 7-2 

# killifish, striped mullet, flathead catfish, gulf pipefish, brown sh rimp, pirate perch, and fiddler

crab were only found in the “light” sampling.



# 7.4 Tidal Flow Conditions and Effect s on Impingement & Entrainment

The Charenton Canal is located in a coastal ar ea with a hydraulic connection to the Gulf of

Mexico. This water level of the Charenton Cana l is subject to tidal exchange, wind activity, and

variable freshwater input which a ffect water quality parameters such as D.O. and salinity. These

variable conditions were likely a factor in the obs erved fish and shellfis h abundances during this

study.

During the sample week of May 15, 2007, impi ngement and entrainment densities were

substantially greater than other sample weeks during the lights on/lights off sampling; possibly

due to a previous rainfall and tidal flow conditions. A total of 4,580 entrained organisms were

collected during this sample even t representing 95% of all entrai nment collected during the lights

on/lights off sampling during, April 2007 and May 2007. A total of 4,880 impinged organisms

were collected during this sample event repres enting 86% of all impingement collected during

the lights on/lights off sampling during April 2007 and May 2007.



# 7.5 Results

During the study, mean impingement and entrainm ent (all stages – egg, larvae, juvenile, and

adult) were higher during all “no-light” sampling bl ocks compared to the same periods of “light”

sampling blocks. There was no apparent mean difference in impingement or entrainment

between lights-on vs. lights off during this shor t two month study. However, a more intensive

study, targeting periods of peak abundances of impingement and entrainment, may reveal

substantial differences.

# 8.0 Equivalent Adult Loss

Equivalent adult loss (EAL) models have be en developed over the past 30 years (Goodyear

1978, Horst 1980, and others) from numerous impact assessments that allow for comparisons of

the impact of power plants to other known sources of fish popul ation impacts (natural mortality,

commercial/recreational fishing, etc.). The raw numbers of fish eggs and larvae that are entrained

in cooling water intake structures are quite large on an annual basi s. However, the naturally high

mortalities of these life stages of fish and shellfish require that a similar “currency” is used to

compare the relative impacts of the CWIS on adult fish populations in the source water. Age

specific mortality rates are required to convert the raw entrainment and impingement numbers

into age-1 equivalents. While these mortality ra tes are obtained from publis hed reports, there are

inherent assumptions and sources of variability bu ilt into these rates (e.g., inter-annual variation).

Another required assumption of this model is that the fish population is stable (neither increasing

nor decreasing) and stationary. Furthermore, a host of density dependent factors (e.g., decreased

fecundity with increased populat ion size), which regulate fi sh populations in the natural

environment, are not incorporated into the equivalent adult model.

The numerous assumptions built into the model re sult in a conservative estimate of the “worstcase scenario” in terms of the number of equivalent adults impacted. As with any type of

ecological modeling, the quali ty of the resulting numbers is onl y as good as the data used in the

model. Therefore, the age-1 equivalent adult estimat es in this report should be used with caution

in comparison to specific known/unknown “real world” situations that affect fish populations,

including density dependence, inte r-annual variation, disease, and other factors that can affect

the standing crop of adult fish.

The species impinged at Teche Power Station that accounted for approximately 92% of the

impingement and were evaluated for the ag e-1 equivalent analysis consists of:

• Atlantic croaker

• bay anchovy

• blue crab

• brown shrimp

• hog choker

• Ohio river shrimp

• unidentified shrimp.

The species entrained at Teche Power Station that accounted for approximately 88% of the

entrainment that were evaluated for th e age equivalent analysis include:

• bay anchovy

# N:\CLIENT\CLECO\Teche\LPDES 316b Submittal\ Teche Final IM&E 316b Report4.doc January 2009



# 8-2 

# • mysid shrimp.

The following life history parameters Shaw and Providence researched for the age equivalent

analysis are necessary to build th e equivalent adult model included:

• Age specific survival, egg to larval stages , between larval stag es, postlarval to age

1, and subsequent annual survivorship.

• Age specific sex ratio of spawning adults at each age.

• Age specific fecundity (number of eggs produced per year).

• Length at age. The length at age is used to estimate the age structure of the fish

impinged at the facility.

After exhaustive literature searches for the requ ired data outlined above, it was apparent that

sufficient data was not available to complete this analysis for the most abundant species

impinged and entrained at Teche Power Station. The age-1 equivalent adult loss modeling was

therefore not evaluated for this facility. This type of modeling exercise conducted for facilities

with similar freshwater species assemblages often reveals that th e age-1 equivalent impacts can

often be orders of magnitude lower than the raw numbers might otherwise suggest. This is likely

to be the case for Teche as well; however, age-1 equivalent impact cannot be quantified with the

limited available data.

# 9.0 Physical Parameters

Stream flow data from U.S. Geological Su rvey (USGS) gauging station 073815450 at Chicot

Pass, Louisiana, located approximately 4.2 mile s upstream of the Teche Power Station contains

publicly available data including gage height ( Figure 9-1 ) and discharge ( Figure 9-2 ).

According to Figure 9-1 , the highest peak in gage height was during February 2007 just weeks

after an increase in flow indi cated in the discharge graph ( Figure 9-2 ); IM&E during this time

frame exhibited low numbers. The daily discharge data ( Figure 9-2 ) shows both positive and

negative discharge values in cluding flow reversals.

sampling period June 2006–May 2007.

Temperature, D.O., salinity, and pH were reco rded at the time of the IM&E sampling and

included in the table below ( Table 9-1 ). D.O. and salinity are shown in the graph below ( Figure

9-3 ). In general these parameters exhibited some degree of seasona l variation, typical for this

estuarine water body type. There were two instances of short-term salinity spikes during

September 2006 and October 2006 which may have been attributed to storm-dr iven tidal flows.

D.O. levels and saturation reached a low pointduring July, as expected when the water

temperatures were greatest. Sec tion 4.1.2 explains how salinity a nd D.O. affected IM during the

12-month study. Salinity and D.O. did not significantly affect entrainment.

denoted with an asterisk (*).

In general, two specific parameters, salinity and D.O., exhibited some degree of seasonal

variation, at Teche Power Station, June 2006 through May 2007. Figure 9-4 demonstrates a

narrow range of salinity across a la rge range of IM&E. Only three high D.O. values are near 8

mg/L with only two high entrainm ent events and one low entrainment event. Increased D.O.

does not significantly effect entrainment or impingement; however, low D.O., expected during

the summertime during low flow critical conditi ons, caused an increase in impingement.

# Species Life-History Information

A narrative description of each species of im portance (as determined by abundance) follows

below.



# 9.1 Atlantic Croaker

During the 12 months of sampling, a total of 2 Atlantic croakers were collected through

entrainment and a total of 15,126 Atlantic croake rs were collected thr ough impingement. This

translates to an estimated annual entrainment of 44,771 and an estimated annual impingement of

235,530. The majority of Atlantic croaker impinged included juveniles and adults ranging in size

from 21 to 283 mm TL. Atlantic croaker are me mbers of the croakers and drum family,

Sciaenidae, and are distributed from Massachusetts to the Gulf of Mexico along the Atlantic

coast. Atlantic croakers are bottom-feeders that consume invertebrates such as crustaceans and

worms and occasionally smaller fish. It is f ound on sand and mud bottoms inshore and a variety

of bottoms offshore. Males make a croaking sound using their air bladders to attract females

during spawning season. Spawning occurs offshore in the winter while the eggs and larvae move

inshore to mature.



# 9.2 Bay Anchovy

During the 12 months of sampling, a total of 4,118 bay anchovy were collected through

entrainment and a total of 3,519 bay anchovy we re collected through impingement. This

translates to an estimated annual entr ainment of 113,504,337 and an estimated annual

impingement of 65,659. The majority of bay anc hovy impinged included juveniles and adults

ranging in size from 16-81 mm TL. Bay anchovy are members of the Engraulidae family and are

distributed along the Gulf of Me xico and the Atlantic coast. Bay anchovy consume zooplankton

and small invertebrates and can tolerate a wide ra nge of salinities, from sea to brackish waters.

Bay anchovy are distributed into coastal sounds, bays, rivers, tidal creek s and impoundments.

During the warmer months they spawn in estu arine and oceanic waters over a variety of

substrates and water depths ranging from sha llow to 100 feet, therefore no specific habitat is

critical for this species.



# 9.3 Blue Crab

During the 12 months of sampling, a total of 100 blue crab were collected through entrainment

and a total of 4,227 blue crab were collected through impingement. This translates to an

estimated annual entrainment of 2,361,661 and an estimated annual impingement of 74,433. The

majority of blue crab impinged included juveniles and adults ra nging in size from 4 to 205 mm

TL. Blue crab are members of the Portunidae fa mily, and are distributed in Atlantic coastal

waters from Long Island to the Gulf of Mexi co. Blue crab support on e of Louisiana’s most

# valuable commercial fisheries. Blue crab are bottom-dwellers in every type of habitat from salty

waters of the Gulf of Mexico to brackish wate rs of bays and estuaries. They consume plant

material, small crustaceans, and worms. Spawning o ccurs in high salinity waters at the mouth of

bays whereas juveniles and adult males migrate to lower saline water to tributaries, tidal creeks

and salt marshes where benthic fauna is abundan t. During the warmer months adults occupy

shallower waters while in winter months they burrow deeper channels to remain inactive.

Spawning occurs during the summer.



# 9.4 Hogchoker

During the 12 months of sampling, a total of 29 hogchokers were collect ed through entrainment

and a total of 2,437 hogchokers were collected through impingement. This translates to an

estimated annual entrainment of 1,108,078 and an estimated annual impingement of 49,057. The

majority of hogchokers impinged included juvenile s and adults ranging in size from 15 to 110

mm TL. Hogchokers are members of the flounders and sole family, Achiridae, and are

distributed in freshwater streams and rivers alo ng the coast of parts of North America from the

Atlantic to the Gulf of Mexico. Hogchokers consume worm s and small crust aceans. Adults

inhabit coastal waters also entering fresh wate rs (hundreds of miles upstream). Spawning occurs

in the spring where hogchokers migrate downstrea m. After hatching, larvae then move upstream.



# 9.5 Brown Shrimp

During the 12 months of sampling, a total of 6 br own shrimp were collected through entrainment

and a total of 5,849 brown shrimp were collected through impingeme nt. This translates to an

estimated annual entrainment of 134,312 and an estimated annual impingement of 95,645. The

majority of brown shrimp incl uded juveniles and adults ranging in size from 35 to 128 mm TL.

brown shrimp are members of the Penaeidae fam ily and are a major component of the Gulf of

Mexico shrimp fishery. Spawning occurs in the Gu lf of Mexico where the eggs hatch into freeswimming larvae that move by tidal, wind and cu rrents into shallow estuarine bay areas and

attach to vegetation. Juveniles move into deeper bay areas as they mature. Brown shrimp

consume worms and amphipods. During the winter pos t-larvae remain offshore in the Gulf of

Mexico for a period of time before moving into es tuaries in the spring. Brown shrimp prefer to

inhabit vegetated areas of bays. Juveniles emigrate from bays to the Gulf of Mexico from May to

August with peaks from May to July, in asso ciation with a full moon and tidal cycles.



# 9.6 Ohio River Shrimp

During the 12 months of sampling, a total of 309 river shrimp were collected through

entrainment and a total of 4,374 river shrimp were collected through impingement. This

translates to an estimated annual entrai nment of 10,797,857 and an estimated annual

impingement of 93,017. The majority of river shri mp impinged included juveniles and adults

ranging in size from 12 to 103 mm TL. River shri mp are members of the Penaeidae family and

# are distributed in the eastern United States seab oard to the Gulf of Me xico and are the only

Macrobrachium spp. found in the Mississippi River. River shrimp prefer open side channels and

borders of main channels, especially when the borders are flooded and plant and animal

materials available for foraging. They occupy habita t with low visibility with greater abundances

of suspended particulate matter.

All equipment will be kept in good, working condition th roughout the duration of the

project. For equipment that requires regular maintenance or calibration, such procedures

will adhere to the manufacturer’s recommendations, or a higher standard. The impingement

basket and net liner shall be kept free of holes. If holes cannot be repaired without

compromising the effectiveness of the net, the net shall be replaced immediately. If

damage/holes develop on the metal impingement basket frame, notify plant maintenance

personnel for repair. The net liner shall be rinsed and hung dry after each use. The

debris/fish basket shall be removed from the fi sh return trough when sampling is completed

and stored in a location designated by plant sta ff. Plankton nets shal l also be rinsed and

hung dry after each use.

# 4.0 Impingement Sampling (Providence)

4.1 Initial Set-Up

1. Call the control room within 24-hours of planned sampling time to determine

operational status, and to a nnounce the timeframe of your sa mpling plans, etc. If

records of pump/screen status have not been updated, the cont rol room needs to

begin recording all pump/screen activity at this time, continuing for the duration

of the sample event. Log sheets will be provided to the control room, be sure to

collect the log sheet at the end of each sample event.

2. With the client’s approval, plant operations will be trained to set the impingement

sampling basket at the onset of the 24-hour sampling event to maximize the

efficiency of the impingement sampling. This will be done after a complete

screenwash cycle to ensure that no debris/o rganisms are carried-over from earlier.

Plant staff should also post the “sampling in progress” signage in a conspicuous

location.

3. Place the impingement collection basket into the fish return basin, ensuring that

no organisms escape from the basket during sampling.

4. Plan to arrive at Teche atleast three hours prior to the end of th e first 8-hour

sampling block to allow for set-up and completion of entrainment sampling.

# 5. Call the control room upon ar rival at the plant to conf irm pump operations and the

time of last screen oper ation with control room.

6. Observe the contents of the impingement collection basket. If there has been no

screen activity since the basket was se t at the beginning of the 12-hour sampling

block, it will be empty. Record appropr iate notes regarding unit/pump/screen

operations.

7. If it appears that the basket has been overwhelmed by one or multiple screenwash

cycles, discuss with plant operations staff to determine what their status was. If it

appears that any portion of the collection may have been lost due to heavy debris

loads/clogging, the sampling block must be re-run and attended by Shaw field

personnel.

8. At the end of each 8-hour sample block, a plant operator needs to run ALL

screens associated with A LL pumps currently in operation. This needs to happen

at the 8-hour mark regardless of any previous screen rotations within the sample

block to ensure the collection of th e complete 8-hour composite sample.

9. Determine the length of time required for a complete screenwash cycle. This can

be done by multiplying the number of screen panels by the time required for each

screen panel to pass a fixed point. For ex ample, if there are 50 screen panels and

each one takes 30 seconds to pass through a marked point, the total time required

for a complete screenwash cycle is 1,500 s econds (25 minutes). To ensure that no

debris/organisms are left behind, th e screenwash should continue for two

complete rotations (50 minutes in this example) whenever possible. All screens

should maintain a consistent operati ng speed throughout the wash cycle.

10. For occasions when the fish/debris load s are high, the basket should be checked

and cleared periodically. However, most occasions will not require the

impingement basket to be attended conti nuously. Every effort should be made to

not remove the basket during an ac tive screen wash/rotation cycle.

11. If you’re not certain of the screen operat ions during any sampling interval, verify

with the control room whether any additi onal screenwashes have been initiated

since the net has been set. Note any such derivations from the 8-hour schedule on

the field data sheet.

12. Upon completion of the first 8-hour sample block and screenwash cycle, lift the

collection basket out of the sluiceway and remove all debris/organisms. Place all

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 8 

# debris/organisms into buckets to be sort ed. Large debris (branches, trash, etc.)

may be discarded as directed by plant sta ff, only after inspected for fish/shellfish.

13. Replace the collection basket back into the sluiceway for the next 8-hour sample

block. Repeat the above procedure for the remainder of the sampling event.

14. Repeat the above procedure (starting at step #8 above) at the end of the second

and third 8-hour sample blocks.



# 4.2 Sample Processing & Identification

1. At the end of each 8-hour sampling block, th e contents of the impingement basket

need to be sorted and processed. Remove the entire contents of the impingement

sampling net into 5-gal buckets or directly onto a sorting table. Pre-sort any

organisms to be identified/measured.

2. Keep all other debris in a bucket(s) to be re-inspected for any overlooked

fish/shellfish. DO NOT DISCARD ANY DE BRIS UNTIL INSPECTED

CAREFULLY FOR FISH/SHELLFISH. DO NOT DISCARD ANY

FISH/SHELLFISH UNTIL SAMPLE IS CLEARED OF ANY QC

INSPECTION.

3. Inspect debris for fish/shellfish by filling the bucket containing de bris ~3/4 full of

water. Carefully remove pieces of debris from the bucket, inspecting each

handful for fish/shellfish. Shake clumps of debris in the water to loosen/remove

any organisms. After debris has been removed, any remaining fish/shellfish

should be clearly visible in the bucket.

4. Another field technician shoul d re-inspect the debris fo r any fish/shellfish that

may have been missed by the original sorter.

5. Use the field guides/taxonomic keys to id entify fish/shellfish down to the lowest

practical level, count and measure each individual (mm, total length), note the

condition of each individual, and record all information on the data sheet.

6. Another field technician shoul d re-inspect the organisms identified by the original

technician for any fish/shellf ish that may have been misi dentified. If there is any

discrepancy, a representative sample should be sent to LSU for final ID.

7. Determine the condition of each individual and inspect for any screen marks,

injury, etc. If possible, determine whethe r each individual was alive or dead when

impinged, based on observed condition. Record code(s) on the field sheet

according to the parameters listed below (note that in some cases more than one

code may be applicable):

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 9 

# Observed Condition Code

# 8. Fish impingement at Teche has never been monitored, so it is difficult to predict

numbers and densities prior to initiating this study. Ho wever, if impingement is

extremely high (1,000+ total numbers) at times, a subsampling procedure may be

employed (procedure to be determined).

9. Measure length (total length TL) for fish es, carapace width for crabs, carapace

length for shrimp/crayfish, and maximum shell width for bivalves.

10. While length measurements from all indi viduals is desired, if a large number

(100+) of individuals of a single species have been observed from any sample

event, record lengths from a repres entative subsample of 25 individuals.

11. For individuals that cannot be identified in the field, follow the procedure below:

• 

# Take a digital photograph of the indi vidual on the measuring board. Keep

the individual (and others that are suspected to be the same) in a labeled

bag stored in the iced c ooler and bring back to LSU lab for storage until

positive identification is made.

• 

# Time/date stamp the file and name according to the sample ID information

• 

# Store all questionable/unconfirmed iden tifications until final identification

has been made and the sample has been cleared of any QC inspection.

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 10 • 

# If necessary, fish specimens will be sent to a recognized expert on fish

identification (possibly LDWF).

12. It may be necessary to ship an entire sample collection to the LSU Lab for final

identification and/or QC checks. For either case, be sure to label the bag(s) with

location, sample number, sample block, sa mple date, start/end time, initials of

collector

13. A voucher specimen and digital photograph for each species collected during the

project will be maintained by the LSU laboratory as a refe rence collection for

identification confirmation. If necessar y, photographs only will be used for large

specimens.

14. Other specimens, once identified, count ed, and measured, can be discarded

according to existing protocol at Teche.



# 4.3 Threatened or Endangered Species Protocol

Any occurrences of threatened or endangere d species must be reported to LDWF in

accordance with the scientific collecting permit for this proj ect. While there are no

occurrences of any T&E species for the habita t associated with this intake structure on

Charenton Canal, field personnel should be vigila nt in their observations of all organisms so

that rare species do not get overlooked and/or mis-identifie d as something more common.

For this reason, it is important that all field personnel familiarize themselves with the T&E

species that may have the potential to exist within St. Mary Parish.

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 11 

# 5.0 Entrainment Sampling (Providence)

Entrainment samples will be collected within the same 8-hour sample blocks as

impingement. However, the entrainment samp le collection will only run for the amount of

time needed to collect between 100 to 150 m 3 

# of water from the intake pipe sampling tap

(about 2 to 3 hours). Each entrainment sample must be collected within the same 8-hour

window as the impingement sample block. Follow the procedures listed below:



# 5.1 Set-up/Calibration

1. Confirm with control room whether it’s clear to open the valves on the 4”

sampling tap from the intake pipe

2. With authorization of the control room, close the valve closest to the entrainment

tank and open both valve(s) closest to the main intake pipes. Let the water flow

through the 4” piping system for a few minutes to flush out any accumulated

debris.

3. Close one of the valves closest to the main intake pipe and open the valve closest

to the entrainment tank, allowing water to flow into the tank for another few

minutes to flush, fill tank to appropriate volume.

4. If a flowmeter is used to determine sample flow/volume, ensure that the

equipment is properly calibrated. Otherwise, calibrate the entrainment sampling

tank to determine the time it will take to sample 100 cubic meters of water. This

will be accomplished as follows:

• 

# Drain the collection container that is marked to a known volume.

• 

# Open all necessary valves.

• 

# Time how long it takes to fill the cont ainer (without the net) to the known

volume mark.

• 

# Calculate (or use calibration table) to determine the time required to pump

100 cubic meters.

• 

# Record calibration information and start time on the data form.



# 5.2 Sample Collection & Processing

1. Inspect the plankton net to ensure that ther e are no rips or tears. Check to ensure

that the cod-end bottle fit ting is secured to the net, tighten clamp if needed

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 12 

# 2. Attach cod-end bottle to plankton net, place net over the en trainment tank where

the flow enters the tank. Secure the ne t in place using the appropriate clamps,

boards, etc.

3. Begin sampling by opening the entrainmen t tank valve and allow the water to

flow into the net for the appropriate ti me interval to obtain between 100 to 150 m 3



# of volume.

4. Check the net periodically to ensure that it is secure and that it is not becoming

clogged. Loosen any kinks as needed.

5. At the end of sampling period, close the entrainment tank valve to shut off the

flow into the tank. Remove the net from any clamps/hangers and begin to rinse

all plankton/filtrate towards the cod-end of the net.

6. Gently rinse the entire length of the net in the sampling tank. Be sure not to fully

immerse the 50 cm opening of the net to minimize any losses of organisms from

the net.

7. When the entire length of the net has been rinsed toward the cod-end, grasp the

bottle and slowly decant excess water through the lower part of the net to further

concentrate the sample/filtrate.

8. Use a wash bottle to wash the concentrated filtrate from the lower walls of the net

and back into the sample bottle. Wash-down from the outside of the net only to

avoid damage to, or extrusion of, organisms within the net.

9. At this point the volume in the sample bottle should be ~250 mL (about 1⁄4 the

bottle volume). During times of heavy sample loads, multiple sample jars may be

needed (1 of X, 2 of X, etc.). Note any multiple bottles on data sheet.

10. Preserve the sample by adding enough etha nol to end up with a 5 to 15% buffered

formalin. It is a good idea to keep a stock of pre-mixed 20% formalin solution

(label as such) on-hand so that you can simply double the sample volume with

20% formalin to end up w ith exactly a 10% solution.

11. Label bottles (sharpie on label tape) and in ternal tags (pencil on waterproof paper)

with the location, sample number, sample block, sample date, start/end time,

volume collected, initials of collector:

123 m 3 

# BKD

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 13 

# 12. Cover and gently agitate to ensure that the preservative is thoroughly mixed with

the sample contents. Ensure that the samp le is labeled and place into cooler (no

ice needed if preserved). Keep in a shade d, cool area until transfer to laboratory.

Include a copy of the data sheet associated with all samples to be transported to

LSU

13. After noting the flowmeter value (total volume sampled), drain the entrainment

tank. Any flowmeter calibrations should be conducted according to the

manufacturer’s specifications

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 14 

# 6.0 Laboratory Processing & Identification (LSU)

Impingement samples will be submitted to the laboratory for a preliminary QC check of

field identifications. These samples will be transported on ice. Always include the

appropriate data sheet with any shipments to the lab. Upon arrival at the LSU lab, the

samples will be processed immediately, or transferred to a freezer. Once field personnel

have passed initial QC requirements, impingement QC inspections by another field

technician will be conducted on an ongoing (100% of samples) basis whenever possible.

Whenever discrepancies exist in the field, sa mples will be shipped to LSU for resolution.

Entrainment samples will be placed in a cooler and transported to the LSU lab after the

completion of each sample week, resulting in 3 bottles for a typical shipment. Always

include the appropriate data sh eet with any shipments to the lab. The turn-around time (to

return data to Shaw) for any given sample should not exceed 6 weeks from arrival in the

laboratory. Fish/shellfish eggs and larvae coll ected will be picked and sorted from each

entrainment sample. Ichthyoplankton will be categorized by egg or larval stages and

identified to the lowest practical taxonomic level, measured, and counted. Taxonomic

identification shall be to the lowest practical level. As appropriate for distinct taxa not

readily identifiable to species level, several representative specimens shall be appropriately

preserved and retained in reference collec tions for possible further identification by

taxonomic specialists. Further identification may be deemed necessary for distinct taxa not

readily identifiable to species if such taxa are (1) represented by more than a few specimens

and are relatively abundant in samples from a sampling date, (2) seasonally abundant, (3)

represented by a few specimens in samples from the majority of sampling dates, or (4)

relatively abundant in samples from the ma jority of sampling dates. Taxonomic

identifications by specialists are not part of th e scope of work for these projects, but may be

determined appropriate based on the above list ed considerations. Enumeration of highly

abundant species at any life stage may be accomplished by subsampling methods that are

widely accepted as valid and considered a ppropriate for enumerat ion of ichthyoplankton.

Due to the limited knowledge-base of identifyi ng shellfish down to the species level, the

“lowest practical level” for the majority of sh ellfish identifications will likely be to the

Order or Family level. The term “shellfish” for the purposes of this project includes

crustacean and molluscan species of dir ect commercial and recreational economic

importance in Louisiana and include the fo llowing taxonomic group s, specimens from

which should be identified and enumerated:

• 

# Freshwater crawfish (crayfish) of the families, Cambaridae and Astacidae

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 15 • 

# Grass shrimp of the Family Palaemonid ae (Palaemontes spp. and Macrobrachium

spp.)

• 

# Oppossum shrimp of the Order Mysidacea, Family Mysidae

• 

# Marine/estuarine shrimp of the Fa mily Penaeidae (e.g., brown shrimp,

Farfantepenaeus aztecus, white shrim p, Litopenaeus setiferus, pink shrimp,

Penaeus duorarum, etc.)

• 

# Crabs of the Family Portunidae (e.g., Callinectes sapidus, etc.) and the Family

Xanthidae (e.g., Menippe s pp., Rhithropanopeus spp.)

• 

# American oyster, Crassostrea virginica

The occurrence of freshwater mussels of the Family Unionidae should be noted, but

identification and enumeration is not required unless significant numbers of specimens are

included in sample collections. Identificati on and enumeration of the Unionidae are not

included in the scope of work for these projec ts. For the purpose of these projects, other

common and abundant taxa of Crus tacea that include species that are sm all in size [e.g.,

copepods, amphipods, ostracods, branchiopod cla docerans, euphausiids (krill)] are not

included in the term shellfish. Further ta xonomic identification may be conducted if

required for some shellfish groups.

The following procedures will be used to process all entrainment samples:



# 6.1 Sorting

1. Upon receipt of samples, check to see that all samples are properly logged into the

laboratory and that the field sheets and bottle labels are correct.

2. Add Rose Bengal solution, if required, to each sample and additional formalin if

needed.

3. Ensure that all laboratory equi pment is in working order.

4. Record the sample number and other header information from the sample field

data sheet to the entrainment laboratory data sheet/log.

5. Place the coarse mesh screen/sieve ove r the appropriate finer sieve (0.300 and

0.500 for Teche & Evangeline, respectively) and empty contents of sample bottle

for a single sample onto the screen. Gently rinse with tap water to remove excess

Rose Bengal and preservative. Efforts should be made to salvage the used

formalin in accordance with the laboratory waste disposal procedures. The LSU

laboratory is responsible for disposing of used formalin.

6. Any larger organisms retained on the upper screen will be identified to species

and included on the data sheet. Lifestages other than egg/larvae will be noted

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 16 

# where applicable. The organisms on the lo wer/finer sieve will be egg/larvae to be

sorted and identified.

7. Place the entire sample, or a manageable portion, in a glass Petri dish, shallow

sorting tray, or other similar device.

8. Sort the fish/shellfish eggs and larvae fr om the debris and place in Petri dish or

vials. If the sorter is familiar with th e species being picked out from the sample,

then preliminary taxonomic groupings can be made. This step will make the

species identification more efficient for the person to ID the organisms.



# 6.2 Subsampling (Splitting)

If upon visual inspection of the sa mple jar, there are very larg e numbers of eggs or larvae

(greater than 1000; approximately) those organisms may be subsampled (split). CONSULT

THE LABORATORY TASK LE ADER BEFORE SUBSAMPLING. Subsampling the

dominant taxon will occur only after sorting the sample to remove less frequently occurring

species or life stages. As a general rule, subsampling should not be conducted on samples

containing fewer than 1,000 ichthyoplankton (eggs or larvae) in the sample. The entire

sample should be processed without subsampling whenever possible. The procedure for

splitting follows:

1. Dilute the sample with tap water to bring the volume to about 250ml.

2. Pour the sample into a Folsom or Mota da-type plankton splitter and split the

sample into two equal aliquots.

3. Pour off each aliquot into separate c ontainers (each is now a 1/2 split) and

visually inspect each aliquot.

4. If large numbers of eggs/larvae still exist, pour off one of these aliquots back into

the Folsom splitter and con tinue splitting in this manner (1/4, 1/8, 1/16, 1/32, etc.)

until the number of organisms in the s ubsample is between 100 and 200. Record

the number of splits on the data form.

5. Sort the sample as above, beginni ng with the smallest split aliquot.

6. Once at least 100 individual eggs/larvae of a given species have been identified

from a 1⁄2 split (or 200 from a 1⁄4 split, so on), the sorter no longer needs to pickout that species from that particular split if the minimum number is met.

7. As an example, when a 1/32 split is examined for eggs, the number of eggs of

each species are recorded. If more th an 550 eggs (e.g. 551) are counted for any

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 17 

# species, the total number of th at species in the sample will be reported as 551 x 32

= 17,632 and that species need not continue to be counted in other splits. If

however, less than 550 eggs of a species are counted in the first 1/32 split, a

second split (1/16) is fully counted (ex cept for those species which already met

the 550 criteria in the first split). When the combined total of the first and second

split (now a 1/16 volume) for any specie s exceeds 200 eggs (e.g. 260), the number

of eggs for that species will be re ported as 260 x 16 = 4,160 for the sample.



# 6.3 Identification & Enumeration

1. Once sorted, species (or lowest taxonomic unit) can be identified, counted, and

grouped by life stage (e.g., egg, larvae, or ju venile). Identifications shall be made

using a microscope with appropriate magnification and lighting to allow for

differentiation of morphologi cal characteristics (pigme ntation, fin ray counts,

myomere counts, etc.)

2. Appropriate early life-stage taxonomic refe rences/keys shall be used to identify

all organisms, based on morphological ch aracteristics. Common and scientific

names will follow the most updated versi on of the AFS standard reference for

fishes, and similar reference for shellfish.

3. Place each life stage (egg, larvae, or juve nile) of each species in a separate vial.

4. Record species, lifestage, and c ounts on the laboratory data sheet/log.

5. The data will be entered into an Excel spreadsheet containing the appropriate

fields (location, date, time, sample even t/block number, sample volume, species, EGGS LARVAE

Split Number Split Number

1/32 550 1/32 300

1/16 200 1/16 300

1/8 200 1/8 300

1/4 100 1/4 200

1/2 100 1/2 100

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 18 

# number, density, etc.) as formatted and provided by the Shaw sampling

coordinator.

6. Data from the lab shall be forwarded to Providence for review, then to the Shaw

Sampling Coordinator for filing and data entry/management & analysis.

7. All processed samples shall be archiv ed by LSU throughout the duration of the

project and for a minimum of one year after the last sample is processed.

# 7.0 Quality Assurance/Quality Control (QA/QC) Plan

The goal of this QA/QC Plan is to ensure that work performance and resulting data &

reports are of the highest quality and provided in a cost-effective, scientifically defensible,

and timely manner. The approach taken by Shaw is to monitor the reliability, accuracy, and

truth of results reported through quality assu rance procedures and to maintain a required

level of reliability through quality control (QC) procedures. All deliverables are subject to

QA/QC guidelines, checks, and reviews. The following specific procedures will be

instituted as part of the QA /QC program for this project.

1. A reference collection of all species of fish found in samples taken during this

project will be retain ed (photos or preserved specim ens). A specimen(s) of each

species (of various sizes, if possible) will be photographed or preserved and be

available for reference should any ques tions of fish identification arise.

2. A thorough system of logging and tracking of data will be instituted and followed.

3. Field personnel will be trained by Shaw to perform required tasks. Laboratory

personnel will be trained by LSU. Dem onstrated proficiency to identify

Louisiana fish/shellfish species, and the ab ility to use a taxonomic key is essential

for both field and lab personnel.

4. A Continuous Sampling Plan (CSP-1), quali ty control protocol to verify the

acceptability of results will be incorporated into the program to insure an average

outgoing quality limit (AOQL). This pro cedure calls for an initial complete

inspection of eight (8) fiel d and laboratory samples. If all of the initially

inspected samplings or error free, a random ly selected sample within a block of

samples is selected. If the random sample passes, a random sample out of the

next block of seven will be processed. This will continue unless a sample fails

inspection after which the plan will reve rt to complete re-inspection until the

prescribed number of samples pass.

5. The field identification QC inspecti on protocol will exceed the CSP-1

requirements by having another on-site fiel d technician re-inspect all sorted

organisms and identifications.



# 7.1 QA/QC Inspection Schedule

1. The sampling coordinator will train all field personnel in the procedures listed in

this manual. Initial QC inspections will be conducted on 100% of samples

collected during “dry-ru n” or preliminary collection date(s).

2. Upon training, field personnel will conduc t QC inspections on all (100%) of

identifications made in the field. No individual inspect their own work. For

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 20 

# occasions when this is not possible in the field, samples will be shipped to the lab

where the laboratory QC inspection schedul e (1 in 7 samples inspected after the

initial 8 passes)

3. Upon training, lab personnel will conduct randomly assigned QC inspections on

identifications made in the lab. One in seven samples will be subject to a QC

inspection and no individual will process more than eight samples without being

subject to a QC inspection. The insp ections will be assigned such that no

individual will inspect their own work.

4. The laboratory manager/task leader will notify personnel when a sample is

scheduled for a QC inspection. This schedule will be based on a random number

table to assign inspections for 1 in every 7 random samples.

5. The sampling coordinator (A Shaw fisherie s biologist) will sc hedule at least one

on-site QA inspection/site-vis it of field and laboratory procedures during at least

one of the first several sample events. This site visit will provi de assurance to the

Shaw project team that the general and pr oject-specific laboratory procedures are

being followed to ensure the integrity of da ta resulting from such procedures. The

sampling coordinator will spend several hours at each field/laboratory site to

monitor adherence to standard operating pr ocedures and to check such things as

accuracy of counts, identif ications, and other measurements. All field and

laboratory sampling/procedural programs will be audited at least once during the

12-month sampling period by Shaw personnel. Reprocessing of field samples

will be conducted for those programs where it is feasible. The reprocessing will

be conducted according to a CSP-1 procedure to assure an AOQ of 10 percent.

Laboratory quality control and quality as surance procedures by task are outlined

as follows.

A. Quality Control

1. Sample sorting/processing/identifications

2. Use of Standard Da ta Sheets/data entry

3. CSP-1 Procedure to Assure 10 Percent AOQL

B. Quality Assurance

1. Laboratory & field procedures inspection by Senior Staff

2. Instrument Calibration as required



# 7.2 Field QC Inspection Pro cedures – Impingement ID

1. All field identifications will be confirmed on-site by a third party (LSU) field

biologist. This procedure exceeds the requirements for a Continuous Sampling

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 21 

# Plan (CSP-1) quality control program used to assure that the Average Outgoing

Quality Limit (AOQL) is 10 percent

2. If any discrepancies exist, the specimen in question will be submitted to the LSU

laboratory for resolution of ID.

3. QC inspections will be conducted in accordan ce with standard procedures listed

in this document, by a person other th an the original sample processor.

4. A collection is termed acceptable if 90 p ercent or more of the total fish of a

particular species have been identified properly . Any discrepancies will be

resolved and the data sheets updated as required.

5. Note that if similar organisms are identified only down to the genus level, but the

QC inspector is able to separate out two or more species, this does not constitute a

misidentification. However, the inspector should inform the orig inal ID’er of the

particular features/characteristics used to make the identification down to the next

level.



# 7.3 Laboratory Ichthyoplankton Sorting QA/QC Procedures

The following specific procedures will be used for the sample sorting component of this

study:

1. A Continuous Sampling Plan (CSP-1) quality control program will be used to

assure that the Average Outgoing Quality Limit (AOQL) is 10 percent

2. A defect will be defined as the sample sorter missing (failing to remove) 10

percent of the total specimens available to be sorted from the sample. When the

total number of specimens initially removed is less than 10, a defect will occur

only if the recheck shows more than one specimen was missed

3. All samples are listed by sample number and assigned QC numbers starting with

one. Quality control sorting is conducted by a qualifie d individual other than the

original sorter.

4. All samples will be in itially inspected until 8 cons ecutive samples are found to be

within the defined limits. Inspection w ill then proceed at one sample randomly

selected from the next lot of 7 consecutive samples until a defective sample is

found. When this occurs, 100 percent re inspection occurs until 8 consecutive

nondefective samples are found. Th en the cycle repeats itself.

5. If the QC value for any re-worked sample is different from the original value, a

resolution is made and the appropriate value is entered on the data form.

# CLECO – Teche IM&E Standard Operating Procedures 01-21-2009 

# 22 

# However the sample will only be considered defective if the difference is 10

percent or more.

6. A record of all QA/QC checks, results and other pertinent notations will be

documented in a QA/QC logbook.



# 7.4 Laboratory Ichthyoplankton Identification QA/QC Procedures

The following specific procedures will be used for the ichthyoplankton identification

component of this study:

1. A CSP-1 program will be used to assure that the Average Outgoing Quality Limit

(AOQL) is 10 percent

2. A sample will be considered defective only if an error of 10 percent or more is

made in identifying or counting ichthyoplankton.

3. When the total number of specimens initially removed is less than 10, a defect

will occur only if the recheck shows more than one specimen was missed.

4. All samples are listed by sample number and assigned QC numbers starting with

one. Quality Control identification is conducted by a qualified individual other

than the original taxonomist.

5. All samples will be in itially inspected until 8 cons ecutive samples are found to be

within the defined limits. Inspection w ill then proceed at one sample randomly

selected from the next lot of 7 consecutive samples until a defective sample is

found. When this occurs, 100 percent re inspection occurs until 8 consecutive

nondefective samples are found. Th en the cycle repeats itself.

6. If the QC value for any re-worked sample is different from the original value, a

resolution is made and the appropriate value is entered on the data form.

However the sample will only be considered defective if the difference is 10

percent or more.

7. A record of all QA/QC checks, results and other pertinent notations will be

documented in a QA/QC logbook.

# 8.0 Data Management & Control (Shaw)

Samples and data sheets will be generated in th e field. Whenever practical, data collected in

the field will be recorded di rectly on data sheets. Thes e sheets will be designed so no

further transcription is necessary prior to input of data into the database. Providence will

retain original field data sheets to compare with the sample and QC data sets generated by

the LSU lab. LSU will submit all laboratory data to Providence for comparison with field

data sheets. Final impingement and entrai nment data will be forwarded to the Shaw

sampling coordinator. Samples to be processe d in the LSU laboratory will be recorded and

logged according to LSU standard laboratory procedures, including QA/QC procedures.

The Shaw Sampling Coordinator will be respons ible for ensuring that all samples, data

forms, and related materials pertaining to the project are properly logged and

recorded/entered into an Access database created for this project . This database will contain

all pertinent information regarding the samples. The data entered will be forwarded to the

appropriate personnel for data pr ocessing, analysis, and reporting.

Data will be entered into an Access database. A log of data entry will be maintained so that

Shaw can provide assurance that all data have been entered and QC inspected. All copies of

data sheets will be stored in the central files of the Salem office. Data entries will be

manually verified and will be subject to QA/QC procedures. A listing of the input data,

identified by a file name and a time and da te, will be produced. This listing will be

examined closely by the responsible task lead er or their authorized representatives for

obvious inconsistencies.



# 8.1 Audits & Control Limits

The sampling coordinator will be responsible fo r the project auditing to monitor the quality

of data produced throughout th e monitoring program. The auditing program is designed to

monitor the reliability, accuracy, and truth of results reported, to determine when corrective

measures must be undertaken to provide a reco rd of Shaw's quality assurance program and

to assure an Average Outgoing Quality (AOQ) of 10 percent for field and laboratory

applications and two percent for data ha ndling. Audits will be conducted by senior

biologists or by representative s designated by the QA officer.

# 8.2 Field & Laboratory Procedure Audits

In field and laboratory tasks, th e level of reliability will be monitored by placing a biologist

who has complete familiarity with the task in to the sampling crew to allow him to monitor

adherence to standard operating procedures and to check such things as accuracy of counts,

identifications, and other measurements. A ll field and laboratory sampling/procedural

programs will be audited at least once dur ing the 12-month sampling period by Shaw

personnel. Reprocessing of field samples will be conducted for those programs where it is

feasible. The reprocessing will be conducted a ccording to a CSP-1 procedure to assure an

AOQ of 10 percent. Field quality control and qua lity assurance procedures by task are

outlined as follows.

A. Quality Control

1. Field Sampling SOP's

2. Use of Standard Data Sheets

3. CSP-1 Procedure to Assure 10 Percent AOQL

B. Quality Assurance

1. Field Inspection by Senior Staff

2. Instrument Calibration as required



# 8.3 Data Processing & Reporting Audits

The level of accuracy of data files will be assure d by file audits and computer error routines.

Database files will be audited for data input and recording errors by the responsible task

leader scanning fields of each file and verifyi ng 10 percent of the content of each file with

the original data sheets. Computer error check s will be made for all species codes recorded

against the species list. When computer re sults are generated by programs, those programs

will be tested with standard data sets to assu re that the program produces accurate results.

This will assure that data handling is accomplished successfully and that computer

programming errors are absent. Any results from calculations not performed by computer

will be subject to a 10 percent spot check. Pr oject files will be examined periodically for

completeness.

The quality assurance officer or his designated re presentative will report the results of audits

in a memorandum to the project manager. Any non-conformances to the QA program or

Standard Operating Procedures and recommen ded corrective actions (or completed actions

# CLECO-Teche Impingement & Entrainment Sampling

SHEET _____ of _____



# if only minor corrections are ne cessary) will be listed in this memorandum. Audit memos

will be filed in the quality assurance file. A dditionally, the following records will be kept of

quality assurance checks:

• 

# Field Procedures: All quality assurance checks will be documented in a QA field

log book. This log will contain a record of any observed deviations from standard

operating procedures and numerical resu lts of auditing procedures such as

independent counts and sp ecies identifications.

• 

# Data File Processing Procedures: A log of all audit checks will be maintained.

Program documentation will be such that steps will be easily followed by an

independent auditor.

Errors which are detected duri ng auditing procedures will be co rrected. In the event errors

are detected subsequent to issuance of a repor t, the report will be amended to reflect the

necessary changes.



# 8.4 Control Limits

Control limits will be used as criteria for action, or for evaluating the significance of

variations between duplicate measurements on th e same sample. Any deviations from SOP

in field tasks that have not been authori zed by the project manager will be considered

significant. Differences in counts, percentage agreement in identifications, and other

measurement tasks which differ by greater than 10 percent will be considered significant.

This 10 percent variation will be the definition of a sample which should be rejected in the

CSP-l.

Any errors resulting from incorrect computer programs will be considered significant.

Errors in computerized data files arising from data entry errors or observed by hand

calculations may not exceed two percent for each file. Errors in database tables and any

other numerical results may not exceed two percent

# Note for Appendix Tables: values of “0.5” for actual numbers as samp led occur for occasions where values were

obtained by averaging from adjacent weeks to obtain a value for a non-sampled week. All estimated numbers are

rounded to one decimal place for concise presentation in these tables, therefore the “Total” for each week may

exhibit apparent rounding errors for a given column/week. However, all calculations for the data analysis in this

report used raw numbers without rounding.Table B -1: Total weekly entrainment (eggs and larvae) densities (number per 100 m3)as sampled during the MORNING sample block.
