Descri tion of Pro osed Action By letter dated May 5, 1983 'Florida Power and Light Company filed a request with the Nuclear Regulatory Commission (the Commission) to amend their operating license by deleting Environmental Technical Specification 4.2, Terrestrial Environmental Monitoring.
Specification 4.2.1:1 required that the soils of the cooling canal banks be analyzed for pH, chloride content and selected nutrients; that test be made to determine erosion rates in both the wet and dry seasons; and that studies be conducted to identify the number and species of fauna associated with these banks and compared to baseline data.
The survey shall include faunal species that are permanent as well as those that are transient.
Specification 4.2.1.2 required that an experimental program be conducted to compare the revegatation of the canal berms using native and/or commercially useful species versus allowing natural revegatation to occur.
This experimental program has been previously completed and deleted.

'DR Specification 4.2.2 required that annual color infrared aer ial photographs at a scale of 1:24,000 be taken in conjunction with ground truthing as an additional monitoring requirement of specification 4.2.1 but especially to study the reinvasion of the berms by native flora, 'such as red mangrove as well as to determine the impact of the canal system on the flora and soil on the areas west and south of the canal system.
II.
Safet Evaluation The amendments delete the non-radiological moni'toring programs related to terrestrial, biological and physical monitoring.
The amendments will not change any current safety limitations related to the operation of the plants.
The safety limits are necessary to reasonably protect the integrity of certain physical barriers. which guard against the uncontrolled release of radioactivity.
In addition, the amendments do not request modification of design features relating to materials of construction or geometric arrange-t ments which could have an effect on safety.
Moreover, radiological monitoring programs are not affected by these amendments.
III.
Environmental Im act of the Pro osed Action In determining the impact of removing the license requirement, the original basis for its inclusion should be recognized.
As stated in the FES-OL (1972),
there was a limited amount of information regardi.ng the environmental impacts from construction and operation of the proposed cooling channel system.
Therefore; detailed evaluations of the environmental impacts were required to be conducted during initial years of station operation.
In evaluating the license amendment
- request, annual reports for 1973,
- 1979, 1981, and 1982 were reexamined.
Specification 4.2.1 - The results of eight years of soil sampling show that phosphorus occurred in consistently low quantities in relation to the needs of most plants.
The results of the analysis of the other soil characteristics were highly variable, which is not unusual.
Studies on erosion rate of the cooling canal berms show that very little erosion is occurring, e.g.,
0.023 ft/yr in 1982.
Plant and animal species will continue to invade the canal berms as a result of natural succession.
The invading organisms are those species adapted to the drier conditions of the berms in contrast to the organisms adapted to the wet habitat which occupied the site prior to construction of the canal system.
Specification 4.4.2 - Color infrared aerial photographs werc taken yearly for eight years.
Examination of photographs for 1973,
- 1979, and 1981 showed only limited vegetational changes.
The results of, on-the-ground sampling provided no evidence of mangrove reinvading the shoreline margin of the spoil berm.
For areas west and south of the canal
- system, analysis of both on-the-ground sampling and aerial photograph interpretation show no significant changes in vegetation from pre-construction conditions.
IV.
Conclusion and Basis for Ne ative Declaration The eight years of studies by the licensee fill the information void of concern at the time of the CP.
On the basis of the foregoing analysis the staff concludes that there will be no detr'imental environmental impact resulting from the proposed action.
Having reached this conclusion, the Commission has further concluded that no environmental impact statement for the proposed action need be prepar ed, and that a negative declaration to this effect is appropriate.
. V.
Safet Conclusion We have concluded that the amendments would not change any current limitations or restrictions relating to plant operation, therefore:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
