Dear Mr. Denton:

~

Please find attached additional information concerning the McGuire Nuclear

Station application for disposal of very low level radioactive waste. This additional information is provided in response to a telephone conference call held on July 16, 1984 between Jerry Swift, NRC, and W. H. McDowell and ChangfuhLan, Duke Power Company.

If there are further questions regarding this matter, please contact us.

Very truly yours, b

Duke Power Company McGuire Nuclear Station

' Application for Disposal of Low Level Radioactive Waste

-Additional Information

'This is inl response to'the concern regarding the chemical behavior of the water treatment' waste and potential transfer of ion-exchange resins, diatomaceous earth and-residues thrcugh ground migration. These questions have been thoroughly analyzed, investigated and approved by the N. C. Depart-ment of Natural-Resources and Community Development, per NPDES Permit

'(

No. NC0024392.

According to this permit. Duke Power is required and' committed to effectively

< maintain -and operate the disposal site so that there is no discharge to the.

' surface waters, nor any contamination of ground waters which will render

'theml unsatisfactory for normal'use.

In order to comply with this, Duke has built a dirt bank-around'the disposal site to prevent any wind erosion and saurface runoff from the' waste raterial application disposal area onto the f+:

. adjacent property and/or surface waters.

'For.any' potential transfer of this material through ground migration,-two test borings (M-1 and M-2) for the Dredge Spoils Area were drilled on 7

June 28, 1982.

M-1 was drilled to 32.4 feet and was terminated in the fill.

M-2 was drilled to 55.8 feet and was terminated in residual soil which was L

.first recognized in.a sample at 50.4-feet. The fill is generally fine

'sa'ndy.siltsJand silty. sands.-. Rock fragments, gravel and tar was noted in several; samples from the. fill.' The two. samples of residual soils are a 1 silty sand and.a sandy' silty clay'. 'The standar'd penetration resistance (N)

~

of the fill. ranges from 'l to -12 with the _ average near 5.

The water table-Jis:st 14-feet in M-1 and atL15'feettin M-2.

The~ water table in M-2' rose to

?ll.2 feet af ter drilling"t'le' hcle to'55.8 feet. Permeability was determined n

~in both' test borings acq32.'4 feet by the falling water level method (permea-

'bilityfmeasured is the mean coefficient of~ permeability). Permeabilities et -

as determined by the tests are:

M-1,-8 x 10-5cm/sec and M-2, 2 x 10-Sem/sec

.j According to these tests and investigations, Duke Power concluded that there will be no impact bn ground water. usages.
