PLAN FOR IMPLEMENTATION OF AEC RECOMMENDATIONS 7b AND 7c of FINAL ENVIRONMENTAL STATEMENT RELATED TO OPERATION OF TURKEY POINT UNITS 3 AND 4 (DOCKET NOS.

50-250 and 50-251)

A.

AQUATIC ENVIRONMENT A program is being developed to monitor and sample effluents discharged from the plant for temperature, salinity and chemical concentrations and the biological variables in the area of potential impact in Biscayne Bay/

Card Sound.

The objectives of the program are to (1) map the area affected by the plant discharges, (2) evaluate the planktonic, epibenthic and benthic characteristics of this area compared with a control area, (3) assess the effects of operation of the cooling system for the Turkey Point power plant on the physical, chemical and biological variables of the estuary and (4) measure re-covery rates of affected areas when Grand Canal and'ther canals open to the bay are closed.

This program, which is designed to provide data on the marine environ-mental impact of the closed and once-through modes of cooling, will include:

1.

Aquata Biota A biological monitoring program will be. conducted to detect any measurable changes in the planktonic, epibenthic and benthic communities of the Biscayne Bay/Card Sound area in the vicinity of the Turkey Point power plant.

The results obtained will be correlated with the condenser cooling water data to determine biological changes that may occur as a

result of operation of the Turkey Point power plant

units.

This information will be further compared with the three years of base line data on the bio-logical characteristics of this estuary system already collected by the University of Miami in a program jointly funded by the AEC and FPL.

a.

E ibenthic biolo Four replicate samples will be collected at each of 12 stations.

Collection will be by seining or trawling at monthly inter-vals and the samples will be analyzed both qualitatively and, where possible, quantitatively for identification of different species

present, their relative abundance, biomass, life history

stage, and size distribution.

b.

Benthic biolo Replicate benthic grab samples will be collected at the same stations as the epibenthic samples once every two months.

Popu-lation characteristics, such as species composition, number of individuals, biomass, diversity and rich-ness shall be determined.

The data will be analyzed to detect any significant measurable changes in specific components of the benthic community.

Samples will be taken to a depth of at least 20 cm, where practicable.

c.

Plankton:

Water samples for plankton analysis shall be 'collected at each of nine stations, in-cluding one station each in the intake and both discharge canals.

and analyzed quantitatively in. terms of sample

volume to establish the dominant genera of the community, biomass, and chlorophyll "a" con-tent.

Primary production will be determined monthly.

and analyzed quantitatively in terms of sample volume to determine generic composition, bio-mass and life history stage.

d.

Attached

rasses, macroal ae and s on es:

Twenty quadrants will be established in Card Sound and Biscayne Bay and examined every two months for

biomass, growth, recruitment and relative health of the plant and animal community.

e.

Macroinvertibrates and fish killed on the traveling screens in a given day once a week at the Turkey Point power plant will be identified by species, size and quantity, and the data will be recorded in

'abular form.

In each periodic report the data will be reviewed to determine whether the sampling fre-quency can be reduced.

In the event of exceptional kills on the traveling screens or in the cooling system canals, notification shall be made within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by telephone or telegraph to the Director of the Region II Field Office of the Directorate of Regulatory Operations.

f.

Entrained or anisms:

The effect of passage through the plant on survival of microscopic plant and animal forms will be evaluated to the level that present

0

"state-of-the-art" techniques will permit.

Representative water samples will be collected once every two weeks at the plant intake, plant discharge, a point partway down the Card Sound

Canal, and at the discharge points of Grand Canal and Card Sound Canalinto Biscayne Bay and Card Sound, respectively.

The samples will be examined for numbers and kinds of representative organisms and their survival at different locations will be measured by the ATP analysis technique.

Results will be compared with similar samples taken from four points in Biscayne'Bay and Card Sound that are outside the influence of power plant operations.

The data obtained from the above programs (paragraphs l.a through l.f) shall be analyzed as they are collected and will be compared with model and analytical predictions and preoperational data that. has been collected.

A report to the AEC of the results of this evaluation will be sub-mitted within 60 days of the end of each six-month period or fraction thereof terminating on June 30 and December 31 of each year.

At. the end of each year, the program and the need for its continuance will be reevaluated.

g.

Tolerance studies:

Laboratory studies will be per-formed as a supplement to the existing programs being conducted by the University of, Miami under AEC/FPL sponsorship to evaluate the effect of short-term

exposures to temperatures and salinities that might be experienced

'under emergency conditions.

These studies will be completed by October 1, 1973 and a final report submitted to the AEC within 60 days thereafter.

h.

Recover in dischar e areas:

Following the con-struction and completion of the Card Sound control structure and closure of the Grand Canal discharge, quadrant stations in the affected area should be established to determine semi-annually the rate of recovery in terms of sedimentation and revegetation by grasses and macroalgae.

2.

Groundwater a

~

Under the direction of the Groundwater Working Group established pursuant to the consent Final Judgment (see discussion below in paragraph C.4.), certain comprehensive groundwater studies are underway which include groundwater monitoring at 23 wells which have been drilled south and east of the cooling system area (many located on property which has been.deeded to the State of Florida).

These wells are checked monthly for water level, conductivity (salinity),

temperature and biocides, and every three months for transmissivity.

Also the program is subject to the continuous review of the Groundwater Working Group.

The first readings were taken on July 1,

1972, and

readings are scheduled to continue until July 1, 1976 after which time continuation of the readings will be contingent upon the decision of EPA in consultation with the U. S. Geological Survey.

b.

A second groundwater program is also underway which utilizes an interceptor ditch located west of the cooling canal system to intercept cooling canal water from flowing westward underground.

A major portion of this program will involve monitoring of 41 wells and 10 surface points for temperature, water level and conductivity (salinity).

The monitoring schedule for these locations varies in frequency from monthly to weekly.

The monitoring schedule is reviewed on a quarterly basis by FPL with the Central and Southern Florida Flood Control District in con-sultation with the USGS.

The monitoring schedule will continue as long as necessary as determined by the CSFFCD and the USGS.

c.

Copies of reports prepared periodically for para-graphs a.

and b. above will be submitted to the AEC simultaneously.

d.

A water temperature survey will be conducted monthly in Biscayne Bay in the vicinity of the Grand Canal discharge and in Card Sound in the vicinity of the Card Sound Canal discharge.

Temperatures just below the surface will be determined with calibrated

thermocouples and strip chart recorder.

Traverses will be made by boat along predetermined courses in the areas of interest.

Information thus obtained will be used to construct isotherms on a map of the area.

In addition, in-depth temperature measurements will be taken at. certain locations along the traverses, and noted on the map.

The data will be submitted within 20 days of the end of each period.

The need for continuance of this program will be reviewed when a pattern is established or at the end of one year.

B.

TERRESTRIAL ENVIRONMENT

l. Baseline Pro ram In order to establish base line conditions that are characteristic of the South Florida terrestrial ecosystem, an intensive and comprehensive three-year research program is being developed that will evaluate the terrain immediately to the south of Turkey Point.

This area is bioclimatically identical to the land being altered for the construction of cooling canals at Turkey Point and has the additional advantage of being undisturbed by any man-made activities at, the present time.

Thus, it will provide control infor-mation against which the impact of the cooling canal system can be more intelligently evaluated than would a short-term impact study involving only the cooling canal land

area, part of which has already been altered in order to meet deadlines required by the consent Final Judgment.

This planned ecological program will include the following:

a.

Definition,of different types and relative abundance of natural plant associations as a function of topography over a l0,000-acre tract of land that in-cludes tidal, mangrove salt marshes, freshwater

wetlands, and dry land communities.

This will include analyses of the characteristics of the soils in which these plants are formed (e.g.,

depth of organic layer, pH, available nutrients, soil profile, salinity, etc.)

as a basis for predicting conditions under which these plant associations will survive.

b.

Study of the kinds and abundance of native animals that live in association with the different. plant communities and utilize them for food and shelter, and breeding.

Xn this phase of the study, field obser-vations and trapping techniques will be used to pre-pare accurate lists of the species noted, especially any rare or endangered

species, and will include birds, mammals, reptiles, fishes and selected invertebrates.

c.

Experimental studies on selected parameters such as (a) peak standing crop of different, plant species as a function of seasons of the year, (b) effect of certain soil characteristics on occurrence of plant association

groups, (c) nutrient turnover in the mangrove salt marsh and its relative contribution to adjacent estuary

areas, and (d) effect of possible groundwater seepage on mangrove ecosystems.

This program will begin by November l, l972.

Reports of the results of the work will be submitted to the AEC yearly within 60 days after each anniversary of the start of the program.

Other related programs are described below:

2.

Im act at Turkey Point Site Data from the above base line program will be compared with information gathered at Turkey Point.

Beginning in the near future, the program at that site will include a

study of the native flora association and their accompany-ing fauna to serve as a means of identifying and correlating this "ground-truth" data with aerial photographs that exist of the area prior to the start of construction activities.

This technique will allow an assessment of the degree of change to different plant community types that has and will result from the construction of the cooling canals.

Results were submitted to the AEC on September 29, l972 and will later be correlated with the base line data to attempt to quantify the long-range ecological effects of construction.

3.

Reve etation of Coolin Canal Banks In addition, a study will be performed to assess the rates and kinds of vegetation that will recolonize the mud spoil banks created as a result of cooling canal construction.

The first step in this program will involve analysis of the soils of the spoil banks for pH, saline content, amounts of nutrient minerals present, temperature, and composition as a function of the height of the soil above the water line.

Soil samples will be taken at points (1) just above the canal

water level, (2) halfway between the water and the top of the spoil bank, and (3) from the top of the banks.

Tests to determine erosion rates in both the wet and dry seasons will also be performed.

At the same time, a

biological study will be conducted to identify the numbers and kinds of fauna associated with these banks as com-pared with surrounding areas at the present time.

This will include both species that are permanent residents (e.g.,

amphibians, reptiles) and transient.

users (e.g., birds) of the habitats.

The advice of agricultural scientists familiar with the flora of the South Florida region will be solicited to predict the feasibility of an experimental program of revegetation by seeding using native species that are tolerant of the soil conditions found in the spoil'anks.

The predicted rate of ground coverage accomplished by this program will be compared with the natural rate of revegetation that occurs through ecological succession.

This latter rate will be determined by studying similar mud banks of the region that have been in place for longer periods of time.

Results of the soil analyses, faunistic survey and initial floristic studies will be used to predict rate and extent of recovery as well as to enhance the extent, of the present level of description of the terrestrial

~ ecosystem."

This report was submitted to the AEC on September 29, l972.

The biological and soil studies will continue on a quarterly basis to evaluate the kinds and

rate of changes actually occurring (both naturally and experimentally) as compared with predicted rates.

Reports will be submitted to the AEC within 60 days of the end of each yearly cycle.

This will include a further evaluation of the program based on all the data obtained to that date, including observations of any undue intrusion of the vegetation into the cooling channels proper in order to assess the total terrestrial impacts of the cooling water channels.

At the end of each year, the program and the need for its con-tinuance will be reevaluated.

4.

Lon -term Monitorin

.In conjunction with the long-term work described in paragraphs l. and 3. above, long-term monitoring of the impacts of the plant will include:

a.

Annual aerial photographs of the site will be taken.

Color and color infrared film will be used with a scale of 1:25,000.

b.

Surveillance will be maintained of canal banks to document changes in edaphic and floristic conditions, especially reinvasion by native flora such as red mangrove.

c.

Limited sampling of soils and flora will be con-ducted annually in the native vegetation west and south of the cooling canals to determine whether the operation of the cooling canals adversely affects the surrounding areas of native vegetation.

The results of this work will be reported annually in conjunction with the.reports in paragraph

3. above.

This program will be reassessed yearly in conjunction with paragraph

3. above.

C.

OTHER ITEMS 1.

Desi n and 0 eration of Dischar e Control Structure In addition to the significant engineering work completed to date on the canal cooling system, a program is underway to develop the information needed to finalize operation of the discharge control structure.

This program includes analytical modelling studies to describe the discharges in terms of temperature and salinity over the full range of cooling system operating and emergency conditions.

Also, the program will involve parameter studies including surface evaporation rate under all plant operating and weather conditions, effects of rainfall, and effects of groundwater exchange.

This program will be completed by September 1973 and a final report submitted to the AEC within 60 days thereafter.

During this same period of time the mechanical design of the control structure will be completed.

Water Circulation in Card Sound and Bisca ne Ba Programs have been underway in conjunction with the Universities of Florida and Miami to develop and validate numerical models for simulation of the hydromechanics of the Lower Biscayne Bay/Card Sound system.

It is planned to continue these programs to (1) improve the models, (2) obtain field measurements of the Lower Biscayne Bay/

Card Sound exchange characteristics, and (3) obtain certain long duration data to further verify the models.

This program will be completed by December

1973, and results of this work will be reported to the AEC within 60 days there-after.

3.

Storm Damage Information developed to date and experience with existing canals at the plant site including actual occurrence of hurricane and flood conditions has indi-cated good resistance to storm damage.

Significant restoration work has not been required.

A limited program will be carried out to define the extent and nature of storm damage which can be expected and to develop a

contingency plan for restoration of the cooling facilities as required.

This work will be completed by September 1973 and a report submitted to the AEC within 60 days thereafter.

4.

Alternate Water Sources In accordance with the consent Final Judgment, work has been underway under the direction of "Working Group 1

Groundwater" to study the availability of groundwater or other alternate sources of surface water for use in the cooling'ystem.

Working Group 1 membership is as follows:
