SUBJECT:
NRC APPROVAL OF CLEVITE SITE CHARACTERIZATION REPORT AND REMEDIATION PLAN
Dear Mr:
Lickfield:
The U.S. Nuclear Regulatory Commission has completed its review of the ' Characterization Report for the Former Clevite Corporation Site,' dated July 2,1997, and the *Remediation Plan for the Former Clevite Corporation Site,' dated July 11,1997. Based on our review, Sevenson Environmental Services, Inc. (SES) has adequately addressed NRC's major concerns on your Site Characterization Report (SCR) and Remediation Plan (RP). Therefore, SES is now authorized to commence remediation of the West wing of the former Clevite Corporation Site, located at 540 East 105th Street, Cleveland, OH.
Although SES has satisfactorily addressed NRC's major comments on the SCR and RP, SES should address the following comments revisions to the SCR or RP, or in the Final Site Survey Plan (FSP).
Provide additional in'ormation to clarify how final surveys will be conducted in lieu of using previous characterization survey data, it should be clearly stated that all final survey activities will be conducted after remediation activities are complete and in accordance with the survey procedures in the final survey plan (including surface scan surveys).
Explicitly indicate that the exposure rate limit is: For Inside Areas - 5 micro R/hr abovo
/
background at im from surface (for inside areas) averaged over an area no greater than g
10m'. Maximum measure cannot exceed 2 times the limit (10 micro R/hr); for Outside Areas - 10 micro R above background at im from surface average over an area no to exceed 100 m'. Maximum measure cannot exceed 2 times the limit (20 micro R/hr).
Provide an explanation for the *0' values listed for the alpha activity in the SCR. Since there are negative beta activity values, the negative alpha va!ues should also be
/Mg '
reported.
Gamma exposure rate measurements typically fluctuate from measurement to
+
measurement. Explain why there is no fluctuation in the exposure rate measurements provided for several rooms in the SE wing.

Explain how the grid block averages were performed, and how the calculations
+
accounted for the size of the hot spots.
Explain the rationale for isotopic sample locations. Explain why Th 228 was not
+
included in the analysis for samples collected on 7/9/96.
Explain why the standard deviation of gamma exposure rate measurements for Room
+
13 A and 13 B is listed as 0, is this an error, given that over 80 measurements were taken?
Explain the process for determining if an unaffected area needs to be reclassified as an
+
affected area. How is this decision made when the MDA's for detectors are greater than 25% of the guideline value?
At the March 11,1997, meeting at NRC, you indicated that remediation would take approximately four weeks, and that the final site survey would begin immediately thereafter.
NRC must review and approve the final survey plan before the survey can be conducted. NRC review and approval may take as long as 30 days. Therefore, in order to avoid delaying the start of final site surveying, SES should address the above comments and submit the Final Survey Plan to NRC as soon as possible, if you have any questions regarding this letter, please contact John Buckley at (301) 415-6607.
