ISCORS SEWAGE SUBCOMMITTEE MEETING
SUMMARY
Date:
December 5,1997 Time:
9:00 am to 11:15 am Location:
EPA, Washington, DC Attendees: NRC: Phyllis Sobel, Tony Huffert, George Powers EPA: Bob Bastian, Loren Setlow, Mark Doehnert, Alan Rubin Al Colli, Vicki Lloyd DOD: Roy Lovett DOE: Jim Bachmaier EPA /NAREL: Dave Saunders ORISE: Cale Condra Agenda:
Sewage Survey POTW Guidance Document Summary:
Sewaae Survev NRC distributed their comments on the October versican of the draft Quality Assurance Project Plan (QAPP). EPA plans to review the QAPP and then call NRC to discuss NRC's comments on the QAPP and schedule a phone call with NAREL so the QAPP can be finalized. Appendix B (Sample collection information letter) may need to be revised after the QAPP is finalized.
NAREL and ORISE distributed their revised letter report on the analysis of samples from the test sites. NRC (Tony Huffert) and EPA will review the report in the next month so the labs can finalize the report by February 1.
The mem'?ers discussed criteria for evaluating the lab analysis results during the survey. There are two concerns. First, in the alpha and beta analysis decision trees, there is concern that the
4 I
e
?
labs will be analyzing only ash samples. Second, in the labs' reporting of results, how do we identify outliers that mey require further NRC or EPA attention. Phyllis Sobel presented plots of concentration versus percent solids for several radionuclides, gross alpha and gross beta results from the test sites. The plots show two populations - ash and sludge (non-ash). At this time, there is no trend of the data with respect to percent solids.
By adding to these graphs (fo. gross alpha, gross beta and each radionuclide detected in the gamma analysis) in the first few months of the survey, we should be able to visually point out the sludge samples that are outliers. To avoid performing the additional radiochemical analysis on only ash samples, we decided the alpha and beta decision trees should have two decision paths. For the sludge samples, analyze the samples whose alpha or beta analysis is an outlier compared to previous survey results. For the ash samples, analyze the samples with either alpha or beta results that exceed the median of previous alpha or beta survey results. The QAPP needs to be revised to reflect 15is discussion.
The second Federal Register notice en the survey was published on Decernber 2,1997 and the OMB Supporting Statement was delivered to OMB in late November.
POTW Guidance Document Jim Bachmaler discussed an FDA report on accidental releases of radionuclides. The doce modeling in this report could be used in developing dose models for the survey and guioance document.
The group discussed the slow progress in revising the guidance document. NRC and EPA will approach their management to determine if this effort can be assigned a higher priority and a schedule for review.
A worklag group is being formed to address dose modeling. The EPA contact for this group is Lor 7 Setlow; the NRC contact is Tony Huffert.
The next subcommittee meeting will be held on February 25 at DOE. At this meeting we will discuss (1) the NRC/ EPA summary report on the survey design and test sites, (2) the list of POTWs to be sent the questionnaire, and (3) comments on the guidance document.
Action items:
- 1. EPA will review the QAPP. In about a week, EPA will call NRC to discuss the NRC comments on the QAPP and schedule a phone call with NAREL so the OAPP can be finalized before the next subcommittee meetino
- 2. NRC and EPA will send comments to Dale Condra and Dave Saunders on the labs letter report by January 5 so the labs will finalize the report by February 1.
3.' NRC and EPA will approach their management to determine if th? guidance document can be assigned a higher priority and a schedule for review.
