DPR-22 Purruant to 10 CTR 50.59, the holders of the above-mentioned license hereby propose the following chantes to Appendix A, Technical Specifications:

1. Samples Per Year and Analysis Per Year Columns P;oposed Chance hemove tin two columns entitlen "bamples Per Year" and " Analysis h :-

Yea:."

hearon 1or Change Thc i.unbcro under thu t c ol trw terve no real purpose. They vero included whu. the procras was. ncveloped to detemine laboratory analysis time and thvad not have been incorporated in the 'Iechnical Specificatione.

2, Latc Collection Sit << l s

Proposed chann L.snge the collection site for all lake samples from "5 local lakes" r

"I control lake" to "2 local lakes."

K .. on for Change Four and one-half yes.v. of routine environmental monitoring, including two years of power operation, have demonstrated that lake samples are of no value in assessing the Monticello Plant contribution to environ-r:cntal ra:!in tion.

The only way in which the plant can contribute to concentrations of radio-isotopes in lake sites ic through deposition of stack effluents. The

. EX111 BIT A t

contribution from the plant is typically several orders of magnitude below naturally occurring radiation levels. Reducing the number of lake sitec to two will permit clocer attention to environmental media which are more sensitive to the effects of plant operation.

3. 90Sr Analyses Proposed chanter Eliminate the 90 Sr analysis from all samples except:

Precipitation Plankton, Algae or Insects Milk Change the 90 Sr analysis frequency for milk from " monthly" to " quarterly."

Adc! t h< following note t o the bot tom of Table 4.8.1:

"I'941 corcesrre:jons in any of the environmental media me.itortpJUincreast to twice that of the preoperational Sr analysco shall be conducted on the following period, sarples at the indicated frequency until it has been der.nnstrated thct the increase is not attributable to plant operations:

l Sample 90Sr Analysis Frequency Liver Water Quarterly i

lake Water Quarterly Well Water Quarterly

! Lake 6 River bottom Sediment Semi-annually l Plankton, Algae or Insects Semi-annually Aquatic Vegetation Quarterly '

Tish Quarterly

Milk Monthly lopsoil Semi-knnually

. Agricultural Crops Annually at harvert Reason for Change 90S r analysis of water, bottom sediment, aquatic vegetation, topsoil, and arricultural crops is not a useful indicator of the impact of the Monticello Plant on the environment. It has been demonstrated over i

i

, , _ . , ._y_..,.. , . , . _ . .

l i ,

r

'. LXIIIEIT A i

1 the 4 years of routine environmental monitoring that the contri-bution to 90S r in these media from plant operations is impossibic to detect. Calculations conservatively estimate that contributions 1

from th9 plant to the 90Sr concentrations in the samples to be deleted from routine analysis are a factor of 1000 below back ,round t i levels.

l l We will maintain surveillance of 90 Sr concentrations in attached a l g a e , in precipitation, and quarterly in milk since these are e most sensitive indicators of 90Sr in the environment. If ggSrconcentrationsintheseenvironmentalmediaincreaseto i

twice that of the preoperational period, 90Sr analysis of all the .

environmental media deleted from routine analysis will resume at i the original frequency until it has been demonstrated that the

• increase is not attributable to plant operation.  !

4 River Water Sampler Propared Chm n j

j Chr.npe the collec tier e f t :. f rm 600 ft upstream and downstrear v.:h' 1.000 it upstream and downstream, 1

beason for channe lhe 1,000 it distance increases the ficxibility of the sampling area and provides a more realictic area for sampling.

5. Take Water Sampler Propored Chance I

Change the co13cetion frequency from " monthly" to " quarterly (water and ice conditions permitting). "

i

_ Reason for Change Ac explained in (2) above, lake samples have been shown to be of '

little value in assessing the effects of the Monticello Plant on the environment. Reducing the frequency of collection of lake water to quarterly results in a sample frequency consistent with the importance ci the sample.

l

i .

t i

D31IBIT A Seasonal conditions often preclude safe collection of samples. *lhe ad-dition of the phrase " water and ice conditions permitting" would allow a delay in the nomal sample schedule when conditions are hazardous.

i

6. Plankton. Alnac or Insects Ernnosed Change, ,

, Cha tc the co11cetion frequency from " quarterly" to " semi-annually l (wh , availabic)."

Reason for Channe Aquatic insects should be sampled in the spring, and algae or plankton sampics taken in the fall. These sampics are not available late fall, '

winter and early spring.

t

!. Aountic Veneration Sampics l Preposed Channe Under collection f requeta,y, add the words "(when available)."

i' keason for Channg During inuch of the year aquatic vegetation is not avhilabic, copecially in the river.

8. Tish Sampler Proposed Channe l

Under collection frequency, add the words "(water and ice conditions, pc mit t ing) .

Reason for Channe l

', Winter and spring sampling on the river is dangerous and only sporadic sampling is possibic.

c. "f15 Sampler Proposed Channe Add the analysis of individual milk sampics ' from the four closest dairy i fa rmt. for 90Sr and 137C s quarterly and 1311 tnonthly,1311)uring the grating season (June through October), sample collection and 1 analyses will be perfomed wechly.
