liarold Denton, Assistant Director for Site Safety, L TECID11 CAL SPECIFICATIONS - CRYSTAL RIVER UNIT 3 Enclosed are comc:ents on the Jrystal River Environmental Technical Specifications, Non-radiological Sections. The major topics in need of further discussion with the npplicant are:
the condenser tempera-ture rise and the maximum discharge temperature are greater than the temperatures evaluated in the final environmental statement; the variance to exceed maximum temperatures for eight hours before correc-tive action is taken is excessive; and, the proposed temperature moni-toring frequency of once per eight hours is inadequate.
This work was performed by' Thomas D. Cain of the Environmental Specialists Branch.

Section 2.1.1 Maximum t. T Across Condensers This ecction proposes a delta T of 21*F which is 4*F higher than stated in' the FES. The basis.indi-
/
cates that the higher delta T is needed for occasional condenser cicaning. We recommend that a separate specification be added for the higher temperature indicating its frequency and duration.

Section 2.1.2 Maximum l>1scharge Temperature

5 Since the non-routino repnrting requirnaants are bae.ed an this critical patinniy analysis, agreement between the staff and the applicant should be t eached before approval at this package.
Therefore a meeting to discuss this point is approuria te.

Specific coments on detailed items:
a) With regard to Table 4.2-1 (3Lf) 1)
One additional air sampling station is stronjly recommended in order to make a total of three near the site boundaries.
The site boundary in the f;E direction is suggested.
ii)
Sea water sampling should be timed to correlai.e with j
g batch releases of liquid effluents. This means that sanpling
(
.)
- ould be less frequent than monthly for periods when there is no release but no more than monthly for more frc';uent rel >>a ses.
However the conthly schedules should be correla'ed with batch releases so as to indicate maximen environcent,'l concentra tions.
.d h)
A quarterly composite should be analyzed for I!-3 and Sr-p9, 90.
iii) For Crabs, bsters, Shrimp, Fish, Marine Plants a backgrovd
'(37) sample station should be established.
Sampling frmuency
.j for these should specify seaiannually or in season as
?.pp ropri a te.

iv)
Vegetation sample should include leafy vegetables grown
\\
for human consumption and principle food crop.
v)

crops grown witnin 10 miles in prevailing wind directi.on sh mid be include' as st:;gasted in OR'J/SID 72-2.

d) tlith regard to Table 4.2-5:
The " Design Objective Limit of Concentration Increases" valu2s should be based on 'the models presenterl by the steif f in NAS:1-lT58.
{}
e) A specification which requires a semiannual survey of agricultural activity in the area of the plant must ha includad. Often thic is limited to a survey of cows and goats nearer the plant than the nearest sampiing station but for Crystal River where the nearest food crop samnles are so far away it shotild include food crops as well.
