Dear i<r. Ik rry:

f The staff has reviewed the letter with attach ts(bnflosed)senttousfor co ment by Joel Smith, Adainistrator, Office of Air Quality and Solid Maste.

Mr. Snith proposes that the State of South Dakota send these materials to the property owners of Edgemont regarding the status of the "Edgemont Clean-up Action Prograa." On the whole, we agree with the need to inform property owners of the results of all the radiological surveys performed to date.

However, presentation of these results in the fann of the proposed letter, the Interin Property Status Report, and the Interim Report (an NRC contractor document) nay be somewhat overuhelming to the property owner and result in soae confusion as to the status of the property. Therefore, although the NRC is not in any way opposed to the dissemination of infonaation at this time, we feel that a simpler approach to notifying the property owners is nore cN ropriate.

For example, 254 property owners could be notified that all necessary radiological surveys hava been performed at their property and that their property passed all applicable criteria. As a consequence, no remedial action or clean-up will be required on their property.

In the case of those properties that have failed at least ona criterion, it is noteworthy that mst of the required engineering assessments (EA's) have already been conpleted. Since these property our, ors are already aware of an existing preblem at their property, it could be stated that they will be provided with a copy of the full engineering assessment report as soon as it is available from the contr Mtor which will detail the clean-up actions and costs necessary to clean-up their property.

Additionally, there are still 356 properties that although there is no direct evidence of the presence of " residual radioactivity", the structures failed the crah radon progeny sampling protocol.

In these situations, the property owners S 00 8

• FEB 8 1982 should be notified that additional long-tem radon progeny monitoring is necessary. This long-term monitoring is required due to epa's criteria that the annual average Working Ldvel (WL) be less than 0.015 WL including backgrounif anTthe monitoring procedures being followed in Edgemont are the sane as those established for the Grand Junction, Colorado renedial action program.

It might be beneficial to specifically point out to these property owners that the need for long term radon progeny sampling does not necessarily imply that a health hazard exists.

In fact, our experience to date has shown that very few properties that require long term radon progeny sampling will have " residual radioactivity" at levels that will require clean-up actions.

The staff believes that this simpler approach would provide the property owner adequate understanding of the specific status of thei. property and could serve as notification of the need for any further actions or monitoring. We also concur that the results of all radiological surveys perforned at the property to date should be summarized and provided to each owner.

If you have any questions on these coments, please contact Gregory Eadie of rty staff (301/427-4541).
