NPDES PERMIT NO. FL0002208 ST.
LUCIE POWER PLANT PARAGRAPHS B.b AND B.
Thermal Monitorin Pro ram Para ra h B.b A proposed thermal monitoring program to demonstrate compliance with Paragraph B.b of the St.
Lucie Unit No.
1 NPDES permit,, which is "The discharge into the Atlantic Ocsan shall not cause a
temperature rise in excess of 0.8 C (1.5 F) above ambient surface temperature outside a 400 acre zone of 'mixing during the months of June through September, nor a 2.2 C
(4 F) rise during the remaining months.
In addition, the surface temperature conditions within the zone of mixing i<illnot exceed a rise of 3.1 C $5.5 Fg over ambient temperature nor a maximum temperature of 33.9 C
(93 F) as an instantaneous maximum at any point."
A.
To demonstrate compliance with the first sentence of Paragraph B.b, infrared aerial photography will be employed, along-with field measurements for ground truth.
Four flights will be scheduled during the first year of operation of St. Lucie Unit No.
1 after the unit. is availab1e for loading above 80%
power level.
Flights will be spaced at approximately three month intervals, when the unit is operating at high load; A report will be submitted at the end of the year of such monitoring.
B.
To demonstrate compliance with the second sentence of Paragraph B.b, two self-contained recording thermographs will be utilized.
One thermograph, will be located at the surface of the water, at the point. of maximum surface
. temperature of the 'Unit No.
1 discharge.
This point has been determined by previous modeling studies.
A second thermograph will be located at the surface near the intake velocity cap of Unit No.
1 to determine ambient temperature.
The processed thermographs will be of a type similar to the thermographs which have been utilized since August 1970 to provide background ocean water temperature data at-the proposeg discharge point., They will be capable of a sensitivity of 0.5 F
in a range from 40 F to 100 F.
Data will be recovered periodically, reduced,. and a report will be submitted. after the first year of Unit No.
=1 operation.

Entrainment of aquatic organisms and effects due to condenser passage.
~
There will be three approaches employed in developing a data bank on entrainment effects:
A.
In the field, samples will be collected from the intake and discharge canals at monthly intervals to identify the species involved and to quantify how many of each species are potentially affected.
C.
Simultaneously, an information search of published.
literature will be performed.
The purpose will be to gather background information generated by research activities at other locations having the same or related.
species.
.The response of these organisms to temperature and chemical stresses will be emphasized with particular attention to any synergistic response.
At the end of each year's collection of data, a report will be prepared in which the significance of the information will be evaluated...
Background data collected at the site on the Atlantic Ocean from 1971., to 1974 will be utilized to estimate the proportion of the total available organisms subjected to plant passage.
2.
Impingement of aquatic organisms on intake screens.
This will be determined as follows; An individual at the plant will examine screen washings for a consecutive twenty.
four hour period once every two weeks.
The collection obtained will be analyzed for:
A.
Species present,;
I B.
Number of each individual species caught; C.
Total biomass of each species; D.
Average size of the individuals.'caught.
A qualified biologist will analyze these figures every six months to determine the significance in terms of (1) stage of development of the organisms; (2) percent reduction this represents when compared to the total population of the area (determined from background data);
and (3) protection and propagation of the species of the area.
- M 0
3.
Detection of changes in the aquatic biological communities due to plant operation.
For this, the background biological program that has been conducted for four years will be continued with modifications as outlined below.
A.
Xn the field, sampling at different levels of biological organismal complexity will be performed. according to the following schedule:
Phytoplankton Zooplankton Xchthyoplankton Nutrient Analysis
'Benthos Fish Monthly Monthly
'Every Two Reeks
-- Monthly As Needed Monthly
- Also, a cataloguing of other developments in 'the area will be performed.
Changes in the area since the background data were collected may influence any biological alterations noted.
B.
At the end of each year, a report.w'i3,1 be prepared.
This will include a bibliography of literature pertinent'.to the effects of specific chemical and/or physical stresses on species indigenous to the region.
dl Any significant change from the background levels noted in the communities sampled should be detected by the above program.
Conclusions will be drawn as to whether or not any changes observed are the result of operation of the power. plant.
The biological monitoring program will be reviewed at the end of the first two years to determine the necessity and/or extent. of its continuation.
