i Tampa 

### Electric Company 

### is presently operating four coal-fired


### electric generating 

### units at Big Bend Power Station. 

### The 

### site is located

on 

### the eastern shore of Tampa Bay in North 

### - Ruskin, Florida. 

### All four
units 

### utilize once-through cooling systems; each 

### unit circulates approximately 537 

### cfs of water. The four 

### units draw water from a single

intake canal and release heated water 

### to the Bay via a single discharge
canal. To reduce entrainment at 

### the plant, 

### Units 3 and 4 

### were fitted


### with fine mesh screens (0.5 mm); screened organisms 

### were returned to the Apollo Beach northern embayment.



### In fulfillment of 

### the Clean Water 

### Act, an NPDES 

### permit was
obtained by Tampa 

### Electric Company to construct and operate 

### Unit 4. A

316 Demonstration (a) and 

### (b) Biological Monitoring Program 

### was conducted by Tampa 

### Electric Company 

### in accordance 

### with conditions of 

### the

NPDES Permit 

### (No. FL 0000817) and 

### the State of Florida Power Plant Site

Certification (Application 

### No. P.A. 79-12; Case 

### No. 80-1723). 

### The general requirements of 

### the program are summarized in 

### the Final Environmental Impact Statement for Tampa Electric Company, Big Bend 

### Unit 4 (pages 4-64 through 4-66).

Studies conducted by Mote Marine Laboratory (MML) during 1980 on 

### the prototype 

### fine 

### mesh.screen intake 

### structure at 

### the 

### site demonstrated

that 0.5 

### mm mesh screens 

### were effective in screening a majority (>80%) of meroplankton at 

### the site. Studies during 1985-86 on 

### the actual 

### fine 

### mesh

screen system showed that sampling methodology was not adequate to
determine accurate screening 

### efficiencies. All six screens are now in optimum operational condition and sampling methodology has been stream1ined for maximum efficiency.


### An approved scope of work was submitted to both 

### the Environmental

Protection Agency and 

### the Department of Environmental Regulation on March 16, 1987. The objective of this Fine Mesh Screen (FMS) Optimization Study is to evaluate 

### the efficiency of the screens in retaining organisms during the 1987 spawning season, with emphasis placed on obtaining data for the following representative important species (RIS):

### METHODOLOGY

SampJing was conducted from both the intake canal (boat) and the
fine mesh screen platform at the Big Bend Station (Figures 

### 1 and 

### 2). 

### Six replicate pump samples were collected from behind screen 3A 

### (designated

as B-3A), 

### along with 

### six replicate pump samples from 

### in front of both
sides of screen 3A 

### (designated as 3A-West and 3A-East). This was the designated test screen and comprised the samples which were processed at



### MML. Previous engineering studies conducted 

### by Tampa Electric Company
determined that the flow of water was approximately equal across all 

### six
screens; therefore, screen 3A 

### was sampled to provide representative
information that can be applied to all 

### six screens. 

### In addition, three replicate pump samples were collected from behind each of the remaining
five screens (designated as B-3B, B-3C, 

### B-44 

### B-4B, and B-4C) as back-up samples in the event sampling appeared inadequate at screen 3A. 

### The fine
mesh screen deck arrangement, along with the location of the testing equipment, is provided in Figure 2. 

### Pumps were run for 30 

### minutes and sampled three water levels (surface, middle, and bottom) 10 

### minutes at
each level. The flows from each pump were channeled into the intake
screenwell located behind the screens, where the water from each screen

Each sampling event consisted of two day samplings (morning and afternoon) and one night sampling. Screening efficiencies were calcu-
' 

### lated by dividing the values from the B-3A 

### sample by the mean of the 3AWest and 3A-East samples. This provides the percentage of 

### organisms 

# I

# P which were able to pass through screen 3A. Multiplying this number by

100 then subtracting 100 provides screening efficiency. Screening
efficiencies 

### were calculated for each identified species, as well as for
total species at various life stages (eggs, prolarvae, etc.).

3.0 RESULTS

Mean densities 

### of eggs, larvae (prolarvae and postlarvae), and

invertebrates collected 

### over the four sampling dates are shown 

### in Figures 3, 4 and 5. Overall, a strong increase in numbers of organisms

was observed over the 4 sampling periods. Total numbers of eggs 

### from the

first 

### two samplings 13/18 and 3/31) were calculated to 

### be 8311 and 994

eggs per 100 cubic meters respectively, while these numbers increased 

### to 261,516 and 989,766 eggs 

### per 100 cubic meters during 

### the last 

### two samplings (4/16 and 

### 5/12). 

### This 

### is 

### a clear indication 

### of the 

### onset of

the spawning season.
In general, numbers of organisms collected from behind screen 3A

were markedly lower than those collected 

### in front 

### of the screens (3A-West



### or 3A-East). Because of the large variation in numbers of eggs between sampling dates, values had to 

### be plotted 

### on a semi log scale in Fig

### ures 3, 

### 4 and 

### 5; therefore, comparisons between samples from 

### front and

behind the screens appear more similar than actual data. 

### All three sets


### of values showed the same overall trend through time, but numbers of organisms 

### from behind screen. 3A were consistently and markedly lower

overall.

Table 

### 1 presents 

### the summarized 

### results for both the 

### RIS and other species collected in relatively high abundances. Many 

### of 

### the RIS organisms listed 

### on page 

### 1 were either not collected or collected in extremely 

### low numbers during 

### the study. This 

### is consistent with the findings 

### of previous studies at the site. Eggs 

### were dominated by
Sciaenidae spp. and Anchoa rnitchilli. Both of these species were
screened effectively overall, 

### with mean losses of only 2.8% and 8.3%, respectively. Anchoa mitchilli was also the only larval RIS col7ected in high abundances. This life stage was also screened effectively, with a

mean loss of only 11.2%. Other larval RIS (Bairdiella chrvsoura and

any samples behind screen 3A; 

### consequently screening losses for these species are 0. 

### Test results for two important invertebrate species (MeniDDe mercenaria and Penaeus spp.) indicate losses are nearly 0

these organisms. Finally, three other larval species collected in high
abundance (Blenniidae spp., Gobiidae spp., and Gobiesox strumosus) show
somewhat greater losses 

### and higher variability. The lower efficiencies
for these groups of fishes may be due in part to their habitat requirements. They are demersal fishes, living on 

### or very near the bottom and utilizing pilings, rock, or dead shell material as habitat, similar to
that found in the screenwell. The relatively high numbers of these taxa which were found behind screen 3A-rnay represent (at least in part) an

### The 

### FMS system is 

### functioning effectively in the screening of meroplankton in general, with consistently high screening efficiencies observed through the majority of the samplings.
2- 

### The FMS 

### system appears to be more effective in 

### the screening of



### eggs than larvae, although both life stages maintained effic ;en

### cies greater than 80% 

### in general. following statements can be made:

### 3.

4.

5. 

### Eggs and 

### larvae of the most abundant 

### faunal groups collected during



### the study, anchovies and 

### sciaenids, 

### are effectively screened 

### at
all 

### life stages, although 

### there are isolated occurrences of 

### lower screening efficiencies.
Other common groups encountered, such as the Families Blenniidae

and 

### Gobiidae, exhibit lower screen efficiency 

### most likely-related

to the 

### spawning of 

### established 

### populations of these 

### groups behind
the screens.
The FMS 

### system 

### is effective 

### in the 

### screening of 

### important

invertebrate species.

### 1aboratory analysis of meroplankton. Samples 

### were processed at 

### MML in 

### a manner 

### so that 

### each sample 

### or subsample was traceable to 

### its collection, and all data reported for


### these portions of the study 

### were both valid and documented. Procedures



### were 

### as follows:

1. Each aliquot was examined 

### twice, with agitation between
examinations. To check for identification efficiency, all samples 

### were reanalyzed arid verified 

### by a qualified

individual other than the person who conducted 

### the initial sorting and identification.

2. Identification of larval specimens was made through 

### the 

### use
of standard literature sources for each RIS. A reference
collection of taxonomically confirmed species was maintained.

3. Subsampling was accomplished by 

### use of a 10 

### m'l Tipet dispenser or 5 ml pipet for numerous eggs. The sample 

### was placed in an appropriately sized Erlenmeyer flask 

### after the

volume was adjusted to allow 

### efficient sorting. The sample

was agitated thoroughly, and aliquots 

### were drawn off into a gridded petri dish. Depending on 

### the density of plankton,

up to four aliquots 

### were sorted at one time.

4. Samples which contained a high density of Anchoa spp. postlarvae were split to allow for more efficient sorting.

Initial and 

### rinse volumes 

### were placed into a plankton splitter and .separated into 

### a usable volume. This portion

of the sample was sorted as above. The remainder of the sample was sorted for all other species and life stages.i
