Dear Members of the ISCORS Sewage Subcommittee:
I invite you to attend the next meeting of the ISCORS Sewage Subcommittee to be held on March 26, 1998, from 9:00 a.m. to noon.
The meeting will be held at Fort Detrick in Frederick, Maryland.
The directions to Ft. Detrick from the Washington, DC area are to take I-270 North to Frederick, and follow Maryland Route 15 North to 7th Street (about 2 miles).
Bear right at the bottom of the exit and proceed straight in the left lane for about 3 blocks.
Enter Fort Detrick, stop for the guard, and proceed to Building 810 (the big building across the field behind the flag poles).
The meeting will be on the 2nd floor in conference room 2.
After the committee meeting, lunch will be available. Then a briefing and tour of Fort Detrick has been arranged, to include the sewage treatment plant and the radioactive sludge.
The purpose of this subcommittee meeting is to discuss progress on the sewage sludge / ash survey and the guidance document for POTW operators. An agenda and the summary of the last subcommittee meeting are enclosed.
Please call Roy Lovett at 301-619-3156 if you plan to attend.
I look' forward to meeting with you on March 26.
If you have any questions about the meeting, please call me at (301) 415-6714 or Bob Bastian at the U.S.

ISCORS SEWAGE SUBCOMMITTEE DRAFT MEETING
SUMMARY
Date:
February 25, 1998 Time:
9:00 am to noon Location:
DOE, Washington, DC Attendees:
NRC:
Robert Nelson, Phyllis Sobel, Tony Huffert Lee Abramson EPA: Bob Bastian, Loren Setlow, Alan Rubin, Lowell Ralston, Behram Shroff, Cheng Hung. Dale Hoffmeyer D00: Roy Lovett DOE: Jim Bachmaier EPA /NAREL:

Sewage survey Dose modeling Summary:
The second Federal Reaister notice on the sewage survey was published on December 2.
On January 23 NRC and EPA met with OMB to discuss the survey, OMB asked 'for an ' additional submission with a more detailed description of the survey design and.NRC sent a response _to OMB on February 20. The response includes the draft report on the survey design, a sample of the letters to be
!sent to~ the POTWs,.the sample collection instructions, a clarification of the purpose of the survey with~ regard to rulemaking, and NRC's response to the v
v
u.
industry request for a steering committee.
OMB plans to complete their review in the next few weeks.
On February 4. the NRC and EPA staffs briefed Larry Weinstock and John Greeves on the status of the survey.
This briefing was an action item from the last ISCORS meeting.
Loren Setlow finished his review of the latest draft of the Quality Assurance Project Plan (0 APP) for the survey.
In March. Mary Wisdom of EPA /NAREL will revise the document to. reflect the latest changes in the survey design and then provide a copy to NRC for a final review of the OAPP. Jill Lipoti noted that in the QAPP EPA should consider notifications to the States if an elevated level of a radionuclide is found.
EPA suggested that the POTWs with elevated levels be given the results as soon as possible, so they can notify NRC EPA. or the State (as appropriate).
NAREL and ORISE distributed their revised letter report on the analysis of samples from the test sites.
There was some discussion about whether to conduct Carbon-14 analyses.
None was found in the samples and Dale Condra stated that based on his experiences, none would be expected to be found.
Furthermore. NAREL does not have an approved procedure for Carbon-14.
Since Jill Lipoti felt that Carbon-14 might be detected at a small POTW, NRC and EPA will consider whether some samples analyzed by NAREL for POTWs associated with j
Carbon-14 sources, such as research labs. might be sent to ORISE for Carbon-14 j
analysis.
\\
Lee Abramson is analyzing the results from the test sites to determine if there are significant differences between the ORISE and NAREL results.
One concern is the fact that all the gross beta ORISE results are slightly larger than the NAREL results though of the same order of magnitude.
ORISE is currently reviewing items that may contribute to the differences between the gross alpha / beta results. Tony Huffert. Tom O'Brien. Dave Saunders and Dale Condra plan to discuss the analyses further.
Loren Setlow is developing an executive summary for the lab's report. Tony will provided Loren some input for the lab's report to further clarify the results. The subcommittee will review the report by March 11 so the labs can finalize the report.
Dave Saunders suggested that NRC and EPA request the POTWs to collect and return the samples within one week of receiving the sample collection materials.
Bob Bastian suggested this request be discussed with AMSA.
The latest draft of the summary report on the survey design and test site results is contained in the February 20 letter to OMB.
Jill Lipoti suggested that the procedure to select POTWs include POTWs associated with:
(1) facilities that discharge non-AEA materials to the sewer system: (2) DOE
v~.
sites: (3) D00 sites; and (4) radioactively contaminated sites identified by
- EPA. -Jill Lipoti-also requested that: (1) small flow POTWs be given appropriate weighting during the POTW identification process; and (2) the timing of sampling be considered to catch large disposals into the sewer system.
EPA will have its NORM contractor suggest (1) POTWs associated with industries that discharge radionuclides but are not NRC licensees and (2) POTWs in high NORM areas.
After OMB clearance is granted, NRC will send a letter to the NRC's Agreement States asking them to identify POTWs for the survey:
these could be 'P0114s associated with TENORM and NARM licensees.
EPA will send a similar letter.to the non-Agreement States.
The design report will be finalized in late March and then placed on EPA's Internet home page.
The' dose modeling working group discussed its plans.
EPA may require a-0 APP or protocol for the dose modeling effort. At the working group's next
- meeting, Alan Rubin will review the pathways used for the 10 CFR Part 503 rulemaking.
EPA's NORM contractor is examining the range of values for radioactive materials in sewage sludge and using these values in analyses for
.several pathways.
These dose modeling results will be included in EPA's diffuse NORM report.
The subcommittee. decided to ask ISCORS whether to include a table of acceptable concentrations in the POTW guidance document and the appropriate dose limit for this table.
We may also invite the ISCORS members to meet with the subcommittee to discuss this issue. A dose limit is needed to determine which survey results are elevated.
The next subcommittee meeting will be held on March 26 at D0D in Fort Detrick, Maryland. At this meeting we will discuss: (1) the list of POTWs to be sent the questionnaire: (2) comments on the guidance document; and (3) the status of the dose modeling working group.
Action Items:
1.
In March,. Mary Wisdom of EPA /NAREL will revise the OAPP to reflect the latest changes in the survey design and provide the revised QAPP to NRC for a final review.
2, The subcommittee members will send their comments on the labs report to Loren Setlow by March 11 so the labs can finalize the report.
3.
Lee Abramson will analyze the test site results to determine if there are any significant differences between the ORISE and NAREL results.
~4.
NRC;and EPA wil1 consider whether to continue Carbon-14 cnalysis in the survey.

9..
5.
Bob Bastian will discuss with AMSA the possibility that POTWs collect and return the samples within one week of receiving the sample collection materials.
6.
The subcommittee members will send their comments on the draft summary report on the survey design and test site results to Phyllis Sobel by the end of March.
7.
EPA. D00 and DOE will compile lists of POTWs associated with:
(1) facilities that discharge non-AEA materials to the sewer system: (2) DOE sites: (3) D00 sites: (4) radioactively contaminated sites identified by EPA:
and (5) high NORM areas.
8.
Loren Setlow will schedule a meeting of the dose modeling working group.
