APR 16 $3 Dock 2t No. 50-302 Mr. Howard Zeller Environ:acatal Protection Agency Region IV 1421 Peach Tree Street Atlanta, Ca.
30309
Dear Mr. Zeller:
Attached is a proposed environmental monitoring program developed by the AEC staff for the Crystal River site which would provide the infornation necessary to caLe a determination concerning the acceptability of once-through cooling for Crystal River Unit 3.
Representatives of the AEC will be ready to discuss an environmental monitoring program in Atlanta with EPA and DOI on April 23-24, 1973.
I suggest we use this proposed program as a basis for discussion during the meeting. The AEC will then review the resulting progran with the applicant at an early date.
Sincerely, Ori2 nal signed by i

l.
=
Purpose To obtain the necessary information on aquatic organisma 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 operation of Unit 3, thereby providing a basis for a decision with regard to the need for a closed-cycle cooling sytem for Unit 3 by November 1974.
5.,
General Discussion The AEC staff requires additional information in order to establish a quantified estimate of impact on the aquatic biota from the operation
.i of Crystal River Unit 3.
Of necessity this assessment must be based on data collected in conjunction with the operation of the oil-fired Units 1 The specific areas of concern are entrainment of organisms through and 2.
the condensers; impingement of organisms on the intake structure; thermal and chemical impact in the discharge area; and biota surveys in areas which may be affected by candidate alternatives to the proposed once-through cooling system, In conjunction with the study program required in each of these areas given below, the applicant will concurrently initiate and com-plete detaildd environmental assessments of alternative cooling systems to identify the one or two systems which would impose the minimum Lm s.

Specific Programs I.
Entrainment A.
Objectives To provide information on the species and quantities of
- 1. -
plankton and fish eggs and larvae passed through the condenser cooling water system.
To determine if losses observed from condenser passage could 2.
create adverse effects on the existing populations in the receiving water 3.
To determine the source or sources of cooling water and variations during high fresh wic< r runoff periods and during unusual wind o other conditions.
B.
Procedures for zooplankton and ichthyoplankton 1.
Length of program:
12 months of data will be collected and analyzed prior to Nov. 1974.
2.
Sacpling stations:
3 stations will be established in each of the.three areas shown in Fig.1 (p. 54 Environmental Research Programs at the Crystal River Power Plant - A Technical Discussion); two stations shall be sampled in the intake canal, one directly in front of the intake structure and another within the canal near the mouth of the double-diked section.

3.
Temperature and salinity measurements should be performed
-to assist in establishing extent of thermal plume.
C.
Water chemistry measurements should be conducted in the mixing zone to establish present characteristics and composition.
D.
The mathematical model of the thermal plume should be verified and/or modified in accordance with the above information.
E.
Thermal / Chemical ef' cts on biota 1.
The laboratory and field research program as outlined in Table 1, p. 89 of the applicant's program will quantify the abundance and distribution of macrophytes, macroinvertebrates and vertebrates. The exact number and location of these
_ stations must be carefully coordinated in order to obtain the maximum usable data.
2.
Organisms caught in plume: A program similar to that con-ducted in areas 1, 2 and 3 of the intake side of the plant is required to idet.tify the presence, movement, and mortality of the following organ!sms in the plume area.

Reports and Program Changes Quarterly reports from the above programs are required initially.
The first reports will be utilized by the staff to judge the adequacy of the program and to determine what changes may be appropriate or necessary to improve the data collection.
These ch.anges will be coordinated with other agencies prior to implementation.
Changes to the program may be submitted by the applicant at any time for consideration by the staff.
Technical Specifications Non-radiological technical specifications (Tech. Specs.) must be developed for the operation of Unit 3.
The applicant is to provide its proposed Tech Specs for staff review prior to November 1, 1973.
