Dear Dr. Templeton:

=

Attached is the AEC Related Environmental Research Programs at the Crystal River Plant Site.

^'

This' program was developed af ter discussions with EPA and DOI at the

((

EPA's Region IV office in Atlanta, Georgia, on April 23-24, 1973.

==

Following these meetings the program was presented to the applicant on April 25, 1973,' by AEC representatives. The applicant was advised to contact the AEC during the week of April 30, 1973, to establish a firm schedule for submittal of its detailed plan to implement the AEC's program.

The program as contained in.the attached document will be incorporated in the Final Environmental Statement af ter making necessary editorial changes.

Sincerely,

To obtain the necessary data of the Crystal River Site area 7

1.

drom a coordinated and comprehensive hydrological: investigation.

To identify and quantify those factors that have impacted the 2.

Crystal River environment and to obtain necessary information on aquatic organisms and water chemistry in the Crystal River Site area in order to be able to assess the potential impact on the aquatic biota from. the g.

'c operation of Unit 3.

Objective To provide a basis by -November 1974 for a decision with regard to 3.

~-4 s..

General Discussion The AEC~ staff after discussion with oth,,er interested federal agencies requires additional information in order to predict-the incremental impact on the aquatic; biota -from the operation of Crystal River Unit 3.

Of necessity -this assessment must be based on data collected in conjunction

.with the operction of:the oil-fired Units 1 and 2.

The specific areas of concern are hydrology in the immediate plant environs; entrainment of organisms throughithe condensers; impingement of organisms on the intake we..

and biota surveys in areas which may be affected by candidate alternat!.ves

W In conjunction with the study program required in each of these

- areas given below, the applicant will concurrently initiate and complete

- detailed hydrological-environmental assessments of alternative cooling systems to identify those systems which would impcs e the minimum environ-mental impact taking into account the areas of concern expressed above,

once-through cooling system.

j=

Tne Company should develop a study program in accordance with the recommendations and guidance developed in this document. The Company g

should submitL this program to the AEC for evaluation.

Such evaluation will include review and modification by the interested federal agencies.

Within 90 days, the Company will submit a progress report on this study; following submittal, a meeting will be held with the interested

' federal agencies:to assess progress, results, and evaluate the need to

[a[

modify the program.
