Request for Interpretation of 10 CFR 39.47, "Radioactive Markers"

Title: Request for Interpretation of 10 CFR 39.47,
"Radioactive Markers"
See the memorandum from J. E. Glenn to R. J. Pate dated
January 9, 1992. This NMSS memo responds to Baker Sand
Control's October 29, 1991 request to terminate NRC License
No. 50-21402-01. In its request, Baker Sand indicated that
it would only use (and supposedly receive) 1-microcurie
cobalt-60 markers, and pursuant to 10 CFR 30.18, it would
not be required to be licensed. While 30.18 (a) states, in
part, that individuals may transfer "exempt" quantities,
this provision has been interpreted by NRC legal staff
(Enclosure 1) as meaning an occasional or infrequent
transfer on a noncommercial basis. For example, this
provision allows laboratories to occasionally transfer
radioactive tissue samples, tagged compounds, counting
standards, etc. Often the radioactive properties of the
items are only incidental to the transfer of the materials.
HPPOS-131 and HPPOS-189 contain related topics.
10 CFR 30.18 (a) also states that a person is exempt from
the requirements for a license, except as provided in
paragraphs (c) and (d) of that section. Paragraph 30.18 (c)
indicates that the section does not authorize transfer of
byproduct material for commercial distribution, and
paragraph 30.18 (d) indicates that no person may, for
purposes of commercial distribution, transfer byproduct
material except in accordance with a license pursuant to 10
CFR 32.18. It is NRC legal staff's opinion (Enclosure 1,
last paragraph) that "commercial distribution" does not
necessarily mean that money must change hands, instead it
implies a transfer into the market or to the general public
resulting in a benefit for the distributor. [Editor's
Note: Enclosure 1 is included in this report as HPPOS-203.]
It is NMSS opinion that Baker Sand would clearly be
transferring the markers for a commercial benefit.
Therefore, transfer of collar markers by Baker Sand is not
authorized under the exemption in 10 CFR 30.18. Baker Sand
does have the option to obtain an NRC distribution license
under 10 CFR Part 32. However, the products must meet the
labelling, packaging, and product brochure requirements of
32.18, and Baker Sand must have a possession license for
each place of storage.
Generally speaking, only under a specific license issued
pursuant to 10 CFR Part 39 is a person authorized to use
(attach to pipe collars) and leave unlabeled radioactive
markers in wells. In developing Part 39, it was understood
that radioactive markers are used and left is well by
licensees. It was also understood that there is a
possibility the well markers may later surface if the will
casing is removed. Based on information for a technical
expert in this field, NRC staff understood that the markers
usually fall to the ground as the casing is disassembled,
but sometimes the markers might be picked up by the workers
conducting these operations. Of course this raised some
health and safety concerns. In an effort to reconcile
these concerns, it was decided to restrict the markers to
the levels of activity listed in 10 CFR 30.71; thus,
reducing any health and safety risks. This issue is
further discussed in Enclosure 2 which is a page from the
proposed rulemaking. This issue is further discussed in 50
FR 13797, the proposed rule for 10 CFR Part 39.
The staff also did not intend to require licensees to
inventory or track the markers after the markers had been
placed in a well. The physical inventory requirements of
10 CFR 39.37 only pertain to the licensee's receipt and
storage of the markers. Nor was there any intent to place
regulatory responsibility on the well owner or operator
after the markers have been placed in a well.
Questions have also been raised concerning reciprocity with
Agreement States. If Baker Sand's Texas or Louisiana
licenses allow the company to use radioactive markers at
temporary job sites, then the company is also allowed to
use the markers under the 10 CFR 150.20 general license.
NMSS does not consider this activity to be a transfer or
disposal. However, Baker Sand would continue to need an
NRC license if it intends to possess and store markers at
its facilities in Alaska.
