I. Summary of the Petition

The NRC received a petition for rulemaking dated April 14, 2017, filed by Matthew McKinley on behalf of the Organization of Agreement States. On August 23, 2017, the NRC published a notification of docketing and request for comment on the petition (82 FR 39971).

The petitioner requests that the NRC amend its existing regulations in appendix B, “Quantities of Licensed Material Requiring Labeling,” in part 30 of title 10 of the Code of Federal Regulations, “Rules of General Applicability to Domestic Licensing of Byproduct Material,” to add appropriate unlisted radionuclides and their corresponding values. Section 30.35, “Financial Assurance and Recordkeeping for Decommissioning,” uses multiples of the applicable quantities of material listed in appendix B to determine the need for decommissioning financial assurance for sealed and unsealed radioactive materials. Licensees using radionuclides not specifically listed in this appendix must use generic default values that the petitioner believes result in overly burdensome requirements.

Without this rulemaking, the petitioner asserts, “regulators are forced to evaluate new products against these [default appendix B] criteria and apply overly burdensome financial assurance obligations or to evaluate case-by-case special exemptions . . . . Rather than issuing exemptions on a case by case basis, the more appropriate way to address the inconsistency in Appendix B['s treatment of listed and unlisted radionuclides] is to amend it to add appropriate nuclides and their corresponding activities, as determined by a rulemaking working group.”

The petitioner also notes that the NRC did not update appendix B when the Energy Policy Act of 2005 amended the Atomic Energy Act of 1954 to give the NRC regulatory authority over discrete sources of naturally-occurring and accelerator-produced radioactive material (NARM). A significant number of medical radionuclides are accelerator-produced. Although the NRC did update schedule B of part 30, which lists possession values of byproduct material exempt from the requirements for a license, to add some NARM, it did not do the same for appendix B, the petitioner points out, even though appendix B is “the driver” for decommissioning financial assurance.

The petition is available in ADAMS under Accession No. ML17173A063.

II. Background

To determine the amount of decommissioning financial assurance required to possess a given radionuclide with a half-life greater than 120 days, a licensee must multiply the appendix B value for that radionuclide by the applicable number in §§ 30.35 or 70.25. Sections 30.35(a) and 70.25(a) require a license-specific decommissioning funding plan (DFP) to possess a quantity of radionuclides greater than provided in the corresponding tables set forth in §§ 30.35(d) and 70.25(d). These tables require specific amounts of funding for specified ranges in the quantity of the radionuclide possessed. Both tables' funding amounts and quantity ranges are identical, but § 30.35 applies to byproduct material and § 70.25 applies to special nuclear material. Although the petition addressed only byproduct material licensed under part 30, appendix B has an identical use for special nuclear material licensed under part 70.

Section 30.35 sets a series of thresholds for decommissioning funding for possession and use of byproduct material. If the license authorizes Start Printed Page 75960possession of an unsealed radionuclide in a quantity more than 1,000 times its appendix B value, the licensee must provide $225,000 in financial assurance for decommissioning. If authorized to possess more than 10,000 times the appendix B value of that radionuclide, the licensee must provide $1,125,000. To possess more than 100,000 times the appendix B value, the licensee must provide a DFP for an amount based on the license's possession limit for the radionuclide. For radionuclides in the form of plated foils or sealed sources, a licensee must provide $113,000 in financial assurance for decommissioning to possess more than 10 billion times the appendix B value for the radionuclide, and a DFP to possess more than a trillion times the appendix B value.

Appendix B also includes possession values for radionuclides not specifically listed. Known as the “default” possession values, these are equal to the lowest values listed in Appendix B for specific alpha-emitting and non-alpha-emitting radionuclides, respectively, and restrict the quantity a licensee may possess without having to meet the applicable financial assurance requirements. For unlisted radionuclides that are in unsealed form and do not emit alpha radiation, the default possession value is 0.1 microcuries (μCi, one millionth of a curie), and for unsealed unlisted alpha-emitters, the default value is 0.01 μCi. Thus, using the table in § 30.35(d), a licensee would need to provide financial assurance for decommissioning funding of $225,000 to possess more than 0.1 millicurie (mCi, one thousandth of a curie) of an unsealed non-alpha-emitting radionuclide not listed in appendix B. To possess more than 1 mCi of such a radionuclide, the licensee would need to have financial assurance for decommissioning of $1,125,000. A DFP is required to possess more than 10 mCi. For unsealed alpha-emitting radionuclides not listed in appendix B, the corresponding threshold quantities are 0.01 mCi for $225,000 in financial assurance, 0.1 mCi for $1,125,000, and 1 mCi for a DFP.

These default values for unlisted radionuclides did not originate with a decommissioning funding purpose in mind. The default values, like the other values now in appendix B, were originally established to conform possession thresholds for the labeling of radioactive materials with the thresholds requiring a license, so that a label would only be required to possess an isotope in a quantity that required a license. The labeling values, issued in 1970 in appendix C to part 20 (35 FR 6425; April 22, 1970), were redesignated in 1993 for decommissioning funding purposes as appendix B to part 30 (58 FR 67659; December 22, 1993).

Appendix B values were not based on an explicit consideration of risk, which involves an evaluation of the probability as well as the consequence of a postulated event. Appendix B values were based on a deterministic approach to regulation, which was widely used to develop early radiation protection requirements (60 FR 42622; August 16, 1995). Under this deterministic approach, the function of a safety limit is to ensure that the consequences of a postulated credible event would be acceptably small. Although the determination that an event is credible involves some consideration of probability, safety limits set deterministically are, by definition, not considered risk-informed, because the probability of the event is not required to be fully considered. Despite their derivation from values established deterministically for labeling purposes, however, the NRC's experience with appendix B's possession values over more than 30 years has shown that they are generally adequate to determine the level of funding assurance required for decommissioning.

The DFP requirements in § 30.35(e) were also established with a different purpose in mind. Originally set forth in the 1988 decommissioning rule (53 FR 24018, 24035, 24043; June 27, 1988), DFPs were intended for major facilities possessing large quantities of radioactive material, not for facilities possessing the quantities of radionuclides typically used by medical licensees. Licensees of these major facilities are required to submit a DFP with a cost estimate specific to their facilities. Although medical and industrial licensees possessing smaller quantities of radioactive material may also develop facility-specific decommissioning cost estimates, it is not necessary to ensure adequate decommissioning funding, and not cost effective for many such licensees. When the rule was issued, it was estimated that very few such licensees possessing such smaller quantities would need DFPs.

These DFPs are subject to detailed requirements for their original content and ongoing maintenance. Under § 30.35(e), DFPs must contain, among other things, a detailed cost estimate for an independent contractor to decommission the site for release for unrestricted use, and a certification that financial assurance in the amount of the cost estimate has been provided. The licensee must resubmit the DFP every 3 years with adjustments as necessary to account for changes in costs and the extent of contamination. Even if a licensee possesses only one radionuclide in a quantity requiring a DFP, that DFP must also cover all other radionuclides at the site, whether or not the aggregated total quantity of these other radionuclides would have required a DFP.

The NRC staff has determined that DFPs are not likely to be necessary for licensees that possess small quantities of certain unlisted radionuclides, particularly if it is returned in its container to the manufacturer/distributor (M&D) after use. This has been the case for germanium-68 (Ge-68) generators of the medical radionuclide gallium-68 (Ga-68).

In an August 2015 report on the effect of the DFP requirement on Ge-68 generators, the NRC's Advisory Committee on the Medical Uses of Isotopes (ACMUI) concluded that “current Part 30 regulations are preventing and/or deterring the use of promising . . . Ga-68 diagnostic imaging agents for patients due to the decommissioning funding plan burden for its parent Ge-68” (ADAMS Accession No. ML15231A047).

After analysis, the NRC staff agreed that the DFP requirement could impede or limit patient access to the radiopharmaceuticals developed from these generators and that a DFP is not necessary to ensure the safe decommissioning of facilities that use them. Pending rulemaking, the NRC staff developed guidance on the issuance of exemptions from the DFP requirement for licensees that have entered into written agreements binding them to return the generators to an M&D and binding the affected M&D to accept them.

Beyond the impact on Ge-68 generator licensees, a decision to forego rulemaking would also be likely to elicit requests for exemptions from existing decommissioning funding requirements by users of other unlisted radionuclides. As noted in Section IV. below, commenters have identified several radionuclides with actual or potential medical applications that are or could be negatively affected because these radionuclides are not currently listed in appendix B.

III. Discussion

The petitioner advances three main reasons for amending appendix B to part 30. First, although Congress gave the NRC regulatory authority over discrete sources of NARM in 2005, the NRC has not updated appendix B to add Start Printed Page 75961possession values for any NARM, which accounts for an increasing number of medical uses.

Second, the petitioner argues that the default possession values for radionuclides not listed in appendix B force regulators either to “apply overly burdensome financial assurance obligations” or “evaluate case by case special exemptions.”

The petitioner's third reason for rulemaking cites the time and cost impacts of needing to request and process exemptions from these requirements on a case-by-case basis. Because of the need for exemptions, “[t]he OAS believes that patient health and safety is being compromised due to licensing delays of important diagnostic and therapeutic products that utilize radionuclides not listed in the 10 CFR 30 appendix B table. . . . Further, development of new products could be discouraged due to these obstacles, diminishing the possibility of new innovative and beneficial options in both medical and industrial applications.”

In its Federal Register document announcing the docketing of the petition, the NRC posed four questions related to the petition's scope. The NRC analyzed the comments received in response, sorted them into 47 categories of common concerns, and traced each category to one of the questions in the notification (See “Categorization of Comments on NRC Questions about PRM-30-66” (ADAMS Accession No. ML18292A481.)) Below are summaries of the principal categories of comments received in response to each of the questions. The NRC evaluated each comment in deciding whether to consider or deny the issues raised by the petitioner. The NRC will also consider the comments further during the development of the regulatory basis document for this rulemaking and any methodology for setting more risk-informed appendix B values. These documents will be made available for public comment.

Summaries of Responses to the NRC's Questions

Question 1: What products or technologies, other than the Ge-68 generators cited in the petition, are being or could be negatively affected because the radioactive materials required for these products or technologies are not currently listed on the table in appendix B?

Most of the commenters who responded to this question stated that LUTATHERA® (lutetium-177 oxodotreotide), a radiopharmaceutical used to treat gastro-entero-pancreatic neuro-endocrine tumors, could be negatively affected because a contaminant in this radiopharmaceutical, a metastable isomer of lutetium-177 (Lu-177m), is not listed in appendix B to part 30.

Commenters also identified several other radionuclides whose use could be unnecessarily restricted because they are not listed in appendix B. Actinium-227, thorium-228, and titanium-44 are being considered for potential radionuclide generators, commenters stated. Silicon-32 has potential therapeutic applications, and sodium-22 and aluminum-26 have potential diagnostic applications. One commenter noted that rhenium-184m should be listed because it is an activation product from certain cyclotron target windows used to produce other radionuclides. Other commenters identified cobalt-57 because the use of products based on or associated with it could be negatively affected.

Question 2: Please provide specific examples of how the current NRC regulatory framework for decommissioning financial assurance has put an undue hardship on potential Start Printed Page 75962license applicants. Explain how this hardship has discouraged the development of beneficial new products, or otherwise imposed unnecessarily burdensome requirements on licensees or members of the public (e.g., users of medical diagnostic or therapeutic technologies) that depend on NARM.

Commenters provided several examples of undue hardship. Commenters said that the DFP requirement is a hardship for medical licensees with multiple locations of use, since a DFP is required for each site using an unlisted radionuclide. Commenters also noted that the need to seek case-by-case exemptions from appendix B's default requirements is an administrative burden, and that the regulatory delays in obtaining exemptions from the financial assurance hardships negatively affect patient care.

Three commenters also said that the NRC should address inequities in applying § 30.35 in different States. One commenter said that the increased financial assurance burden for those possessing accelerator-produced radionuclides “cascades to the Agreement States, which look to NRC for guidance, and absent that guidance they either move forward on their own or temporarily stop processing [license] amendment requests [for exemptions].”

Question 3: Given the NRC's current regulatory authority over the radiological safety and security of NARM, what factors should the NRC take into account in establishing possession limits for any of these materials that should be listed in appendix B?

Thirteen commenters provided a total of 38 recommendations on factors the NRC should consider in setting any new possession limits. Several of these recommendations shared common themes. One was that the NRC should provide special regulatory consideration for radiopharmaceuticals. Four commenters said, for example, that the NRC should consider the unique purpose of radiopharmaceuticals, the importance of patient access to these pharmaceuticals, and the fact that they undergo extensive evaluation by the U.S. Food and Drug Administration before they are allowed to be manufactured and regulated for their radiological properties.

A related theme was that generators using unlisted radionuclides to produce these radiopharmaceuticals also deserve special consideration. Five commenters said these generators should either be considered as sealed sources or as a separate category qualifying for more risk-informed regulatory treatment.

Another theme was that for appendix B to part 30, the NRC should consider possession values already established in other NRC tables. Five commenters said, for example, that the NRC should align the values in appendix B to part 30 with those for the same radionuclides in appendix C to part 20 on labeling.

Two commenters recommended similar sets of considerations with respect to which other factors should be accounted for in setting new appendix B possession values. These included the physical and chemical form and half-life of the radionuclide and its progeny, and the disposal pathway for these radionuclides at the time of facility decommissioning.

Two commenters stated that in determining the amount of financial assurance required for a DFP, only the area of use of the subject radionuclide should be considered. These commenters noted that medical licensees use different radionuclides in different areas of their facilities, and that some of these radionuclides, such as technetium-99 and iodine-125, do not require any financial assurance for decommissioning.

Four other commenters shared a concern that establishing new possession limits in appendix B to part 30 could result in unsafe waste disposal practices. Three commenters submitting a single set of comments argued that possession values high enough to make decommissioning financial assurance requirements more commensurate with the radiological hazards of medical uses could also effectively exempt some industrial and commercial licensees, including those engaged in oil and gas fracking, from a requirement to dispose of their wastes in licensed facilities. These commenters also said that the NRC must prepare a “programmatic” (i.e., generic) environmental impact statement for any rulemaking to amend appendix B.

Two commenters raised issues about the number of radionuclides with half-lives greater than 120 days—the minimum, as noted at § 30.35, for decommissioning funding requirements—that should be added to appendix B. One commenter said that the appendix should list all radionuclides with such half-lives, “since it is hard to predict where the next medically useful radionuclide will come from in the future.” The other commenter noted that appendix B to part 30 contains only 45 radionuclides (the staff counted 49) with half-lives greater than 120 days, while appendix C to part 20 lists 150.

One commenter on Question 3 suggested that, because the factors that need to be considered in setting new appendix B possession limits may change with time, the NRC should review part 30 decommissioning funding requirements every 3 to 5 years.

Question 4: Does this petition raise other issues not addressed by the questions above about labeling or decommissioning financial assurance for radioactive materials? Must these issues be addressed by a rulemaking, or are there other regulatory solutions that NRC should consider?

On the question of whether the NRC should consider solutions other than rulemaking, 15 of the 20 comment submissions explicitly supported the need for rulemaking, and one requested that § 30.35 requirements not apply to certain radiopharmaceuticals approved by the U.S. Food and Drug Administration—a change that can only be effected by rule. No commenters opposed rulemaking, although three commenters that submitted a single set of comments were concerned that setting new possession limits for medical radionuclides could effectively exempt from needed regulation industrial wastes containing those radionuclides. Of those commenters that explicitly supported rulemaking, seven also said it would be preferable to issuing exemptions, and two said that a rulemaking would improve or minimize negative impacts on research, medical licensees, and the availability of new radiopharmaceuticals to patients.

On the question of whether the petition raised any issues not addressed by the other three NRC questions, responding commenters raised 16 additional issues. The majority of these are related to Question 3 on factors to be considered in setting new appendix B possession limits. Six commenters, for example, called on the NRC to address the inconsistencies in possession values between appendix B to part 30 and appendix C to part 20. Two of these commenters recommended replacing appendix B values with appendix C values, and one recommended that the NRC withdraw appendix B and reference appendix C instead.

Two other commenters recommended that the NRC describe the methodology for deriving possession values in a footnote to appendix B to part 30. Providing a formula instead of the current default values for unlisted radionuclides, one commenter said, “will alleviate the need for subsequent amendments to appendix B and minimize [the] negative impact (or potential impact) on medical licensees and patient care.”

Four commenters raised a new issue unrelated to the issues associated with Start Printed Page 75963setting possession limits. These commenters noted that the title of appendix B to part 30, “Quantities of Licensed Material Requiring Labeling,” does not express the actual purpose of the appendix.

V. Reasons for Consideration

The NRC has reviewed the petition in accordance with § 2.803(h). For several reasons, the NRC concludes that the issues raised by the petitioner and commenters should be considered in the rulemaking process. First, the Energy Policy Act of 2005 gave the NRC regulatory authority over discrete sources of NARM, and the NRC needs to incorporate appropriate NARM into its regulatory framework for decommissioning funding. This would also provide a clearer, more predictable basis for Agreement State regulation of decommissioning funding for these radionuclides. Second, rulemaking would also reduce, if not eliminate, the need to process exemption requests from licensees seeking a more risk-informed alternative to the generic default values that result in decommissioning funding requirements that are not commensurate with likely costs.

Moreover, a rulemaking would also advance the NRC's commitment to more risk-informed regulation by better aligning NRC funding requirements with the risks of decommissioning the affected licensee facilities.

In addition, the NRC expects that rulemaking would be more cost-effective than maintaining applicable existing regulations. The short-term savings to the NRC from denying this petition for rulemaking would likely be outweighed by the higher aggregate cost to license applicants, Agreement States, and the NRC for case-by-case exemption reviews over the long term. The higher cost of NRC inaction would accrue not only for Ge-68 generators and the Lu-177 radiopharmaceuticals cited by most commenters on Question 1, but foreseeably for other new technologies. In addition to making costly exemption reviews unnecessary, a rulemaking would also provide a more stable, risk-informed basis for decommissioning funding requirements by using radionuclide-specific possession values that better reflect the amount of financial assurance required.

Further, more predictable and risk-informed decommissioning funding requirements could remove an unnecessary barrier to making Ge-68 generator-supported Ga-68 imaging, Lu-177 radiotherapy, and other emerging medical and industrial technologies that depend on unlisted radionuclides available to the public.

An additional reason to undertake rulemaking on appendix B is to align its title with its decommissioning funding purpose.

Lastly, adding unlisted radionuclides in a single comprehensive rulemaking would minimize the need for additional rulemakings in the future when new applications are developed for radionuclides remaining unlisted in appendix B.
