Mr Stuart R. Levin, Chief - fJUL 1- 192F Division of Radiation Control Bureau of Radiation Protection-Commonwealth of Pennsylvania P.O. Box 8469 Harrisburg, PA 17105-8469 <
De r Mr. Levin: t I am responding to your fax dated May 7,1998, to Dr. Steve Salomon. In that fax, you requested recommendations from NRC in responding to an NRC licensee letter regarding the Proposed Rulemaking published in Pennsylvania Bulletin, Volume 28, Number 7, February 14, 1998. The inquiry grew out of concern for the proposed approach in comparison to the NRC temporary generic exemption for the well logging licensecs from the requirement specified in 10 CFR 39.41 (a)(3). Currently sealed sources that were manufactured before July 14,1989,.
may use design and performance criteria from the United States of America Standards Institute -
.(USASI) N5.10-1968 or the criteria in Section 39.41. The use of the USASI standard is based on an NRC. Notice of Generic Exemption issued on July 25,1989 (54 FR 30883). This
' exemption allows the use of older sealed sources, that have not demonstrated that they meet -
current criteria, to be used for well logging. Sealed sources manufactured after July 14,1989, had to continue to meet the requirements of Section 39.41.
For NRC licensees, this exemption is still effective, but it is not included in 10 CFR Part 39.
Recently the NRC completed a rulemaking plan which, as part of other changes to Part 39, proposes to incorporate the USASI N5.10-1968 requirements for older sealed sources as a new provision in Part 39. The draft Rulemaking Plan was sent to the Agreement States for comments on May 28,1997 (SP-97-036) and current plans call for issuance of a proposed rule
. near the end of year 1998.
In the interim, until NRC completes this rulemaking notice, we suggest that you continue to ;
provide well logging licensees the flexibility that is provided by the generic exemption. The
, method followed by Pennsylvania to continue the exemption in effect is up to the Pennsylvania program. We suggest, however, that the method used be legally binding, and generically applicable to all well logging licensees, such as a rule change, generic license condition, or l generic exemption.
If you have any questions or we may be of further assistance, please let me know. Kevin Hsueh, (301) 415-2598, or KPH @ NRC. GOV, is the Office of State Programs contact for this

Bureau of Radiation Protection re: Comment on Proposed Rulemaking, as per PENNSYLVANIA A BULLETIN , Volume 28 Number 7, February 14,1998.
Dear Dr. Levin.
We would like to make the following comments on Proposed Rulemaking found in the PENNSYLVANIA BULLETIN , Volume 28 Number 7, Februaiy 14,1998:
- 1) CHAPTER 226. RADI ATION S AFETY REQUIREMENTS FOR WELL LOGGING.
Section 226.17 Design and performance criteda for sealed sources.
"A licensee may not use a sealed source, except those containing radioactive material in gaseous form, in well logging unless the sealed source meets the following minimum criteria.. ." 3 We presume that the requirements of this proposed rule (226.17) recognize the " temporary generic exemption published in the Federal Register on July 25,1989 (54 FR 30683). The generic exemption exempted well logging licensees from the requirement specified in 10 CFR 39.41 (a)(3). The exemption applied to (and allowed the continued use of) well logging sources that meet certain ahernate prototype testing criteria." These sources were identified by manufacturer and model number in an attachment titled "_WFIL 1.OGGING SOURCES APPROVED UNDER PART 39 REQUIREMENTS"in a USNRC memorandum dated November 1,1991, to "All Well Logging Licensees" on the subject " STATUS OF WELL LOGGING SOURCES" If proposed mie (22617) does not permit recognition of this generic exemption we would like to suggest that language be added to make such an allowance possible. An intolerable fmancial burden would befall small businesses who currently possess sources of these types, such as ours, if the NRC generic exemption is not allowed.
- 2) We did not see any discussion of fees of any type in the captioned Bulletin. We presume fee stmeture, including annual fees and reciprocity fees will be the subject of future Bulletins u on which comments can be made. g[g 33lJJO S.80.LO]Ul0 Respectfully Submitted b

SUBJECT:
STATUS OF WELL LOGGING SOURCES , g b
in a memorandum dated August 10, 1989 we informed Nuclear Re latory .D Coasnission (NRC) well logging licensee,s of a temporary generic exemption published in the Federal Register on July 25,1989(54FR30$3). The generic exemption exempted well logging licensees from the requirement to use only sealed sources that meet the prototype testing requirement specified in 10 CFR 39.41(a)(3). The exemption applied to (and allowed the continued -
use of) well logging sources that meet certain alternate prototype testing criteria.
The notice indicated that the exemption would remain in effect until NRC ',
published its final findings in the Federal Register. Thus far, NRC has '
been unable to initiate this action due to higher priority activities; however, NRC now anticipates commencing this task in the near future.
Included in the memorandum with the Federal Register notice were three enclosures that listed varisus sealed source models common to well logging e
and identified their suitnility for continued use in well logging operations.
There have been a few changes to the lists since first transmitted. There are a few sources which we have dcitermined meet the criteria specified in 10 CFR Part 39, and have added the sources to tho approved list.
Enclosed are the three enclosures which have been updated on a one-time-only basis to show the apparent current status of known well logging sources.
Enclosure 1 lists those source models which appear to meet section 39.41 requirements and are approved for continued use. Enclosure 2 lists those source models whose continued use is authorized under the temporary generic exemption. Enclosure 3 lists those source models that do not meet the requirements of Section 39.41 or the generic exemption. When a sealed source is contained (and normally stored) within a device (logging tooi), the sealed source manufacturer and model number is shown belpw the entry. When NRC has been able to determine that a sealed source model was manufactured / distributed by another company, or more than one model designation may have been used, this information is shown in parentheses below the entry.. Neutron generators are shown by the designation "Nu SEN." An asterisk (*) indicates that the source is used within the logging tool's electronics package.
