The Nuclear Regulatory Commission (NRC) is amending its regulations regarding the medical use of byproduct material. The direct final rule will clarify the definitions of authorized users, authorized medical physicists, authorized nuclear pharmacists, and radiation safety officers; clarify the notification requirements if the patient is in a medical emergency or dies; clarify the recordkeeping requirements for calibration of brachytherapy sources; correct the title for the National Institute of Standards and Technology; clarify that prior to October 24, 2004, individuals who meet the training and experience requirements in Subpart J may undertake responsibilities specified in certain sections in Subparts B and D-H; and eliminate a restriction that training for ophthalmic use of strontium-90 can only be conducted in medical institutions. These amendments are necessary to clarify certain inconsistencies within the regulations and to allow training in ophthalmic treatment to be conducted in eye clinics or private practices, in addition to medical institutions.

Because NRC considers this action to be noncontroversial, the NRC is using the direct final rule process for this rule. The amendments in this rule will become effective on July 7, 2003. However, if the NRC receives significant adverse comments on this direct final rule by May 21, 2003, then the NRC will publish a document that withdraws this action and will subsequently address the comments received in a final rule as a response to the companion proposed rule published elsewhere in this Federal Register. Absent significant modifications to the proposed revisions requiring republication, the NRC will not initiate a second comment period on this action.
(A) The comment causes the staff to reevaluate (or reconsider) its position or conduct additional analysis;
The NRC published in the Federal Register a final rule amending 10 CFR part 35 regarding medical use of byproduct material on April 24, 2002 (67 FR 20249) (final rule). Subsequently, the NRC staff (staff) identified typographical and editorial errors as well as inconsistencies in the Part 35 final rule. The staff published a document correcting the typographical Start Printed Page 19322and editorial errors on October 9, 2002 (67 FR 62872). Both the final rule and the correction became effective on October 24, 2002. This amendment addresses certain inconsistencies that have been identified in the Part 35 final rule and implements a minor change to eliminate a restriction that training for ophthalmic use of strontium-90 can only be conducted in a medical institution.
(1) Section 35.2, Definitions. In this section, “Authorized medical physicist” (AMP), “Authorized nuclear pharmacist” (ANP), “Authorized user” (AU), and “Radiation Safety Officer” (RSO) are defined as individuals who meet the criteria in certain referenced sections of this final rule. However, the staff has specifically reinserted subpart J (as contained in the proposed rule (63 FR 43516; August 13, 1998)) for a two-year transition period. Therefore, until October 24, 2004, individuals certified by medical boards listed in that subpart are also qualified as authorized users. It is inconsistent to recognize as authorized users individuals who meet Subpart J requirements, but not include them in the relevant definitions in § 35.2.
The definition of AU is therefore amended to include individuals qualified under §§ 35.910(a), 35.920(a), 35.930(a), 35.940(a), 35.950(a) and 35.960(a), until October 24, 2004. Similarly, the definitions of AMP, ANP, and RSO are amended to include individuals authorized pursuant to §§ 35.961(a) and (b), 35.980(a), and 35.900(a), respectively.
(2) Section 35.51, Training for an authorized medical physicist. The second sentence in paragraph (b)(2) states: “The written certification must be signed by a preceptor authorized medical physicist who meets the requirements in § 35.51 or equivalent Agreement State requirements. * * *” However, during the two-year transition period, an individual who meets the requirements of § 35.961 in Subpart J is also qualified to be a preceptor authorized medical physicist. Therefore, this sentence is amended by replacing the phrase “in § 35.51 or equivalent Agreement State requirement” with the phrase “in § 35.51, or, before October 24, 2004, § 35.961, or equivalent Agreement State requirements. * * *”
The following additional sections reflect similar inconsistencies: §§ 35.190(b), (c)(1)(ii), (c)(2); 35.290(b), (c)(1)(ii), (c)(2); 35.390(b)(1)(ii), (b)(2); 35.392(b), (c)(2), (c)(3); 35.394(b), (c)(2), (c)(3); 35.490(b)(1)(ii), (b)(2), (b)(3); 35.491(a), (b)(3); and 35.690(b)(1)(ii), (b)(2), (b)(3). Therefore, these sections are also amended to include the corresponding sections from subpart J.
(3) Section 35.100, Use of unsealed byproduct material for uptake, dilution, and excretion studies for which a written directive is not required. Paragraph (b) states: “Prepared by an authorized nuclear pharmacist, a physician who is an authorized user and who meets the requirements specified in §§ 35.290 or 35.390, or an individual under the supervision of either as specified in § 35.27.” However, during the two-year transition period, an authorized user who meets the requirements of § 35.920 in Subpart J is also qualified to prepare unsealed byproduct material for medical use. Therefore, this sentence is amended by replacing the phrase “in §§ 35.290 or 35.390” with the phrase “in §§ 35.290 or 35.390, or, before October 24, 2004, § 35.920.” In addition, the format of this paragraph has been modified to clearly identify the three categories of persons who can prepare unsealed byproduct material for medical use for uptake, dilution, or excretion.
The following additional sections reflect similar inconsistencies: §§ 35.200(b) and 35.300(b). Therefore, these sections are also amended to include § 35.920.
(4) Section 35.310, Safety instruction. Paragraph (a)(5) provides that a licensee must notify “the” AU if the patient has a medical emergency or dies. However, corresponding sections for brachytherapy and external beam therapy (i.e., §§ 35.410(a)(5), 35.415(c), and 35.615(f)(4)) require that “an” AU, instead of “the” AU, be notified. Section III of the Supplementary Information in the April 24, 2002, final rule states: “Therefore, because of the type of dosages that are administered under § 35.300, we believe it is important that an AU be available to be contacted in case of a medical emergency or death.” Notifying “an” AU should meet this requirement because “the” AU who treats the patient may be unavailable when the patient has a medical emergency or dies. This section is revised to replace the words “the” AU with the words “an” AU.
(5) Section 35.315, Safety precautions. Paragraph (b) provides that a licensee must notify the RSO, or his or her designee, and “the” AU if the patient has a medical emergency or dies. This section is modified to replace the words “the” AU with the words “an” AU for the reasons explained in (4), above.
(6) Section 35.432, Calibration measurements of brachytherapy sources. Paragraph (a) provides in part that a licensee shall determine the source output and source positioning accuracy. Paragraph (b) states that a licensee may use measurements provided by the source manufacturer or by a calibration laboratory. However, it is not clear that the licensee may perform its own measurement or, as an alternative, use measurements from manufacturer or calibration laboratory. For clarification, this section is therefore revised to add a phrase to the beginning of paragraph (b) to read as follows: “Instead of a licensee making its own measurements as required in (a), the licensee may use measurements provided by * * *.”
(7) Section 35.491, Training for ophthalmic use of strontium-90. Paragraph (b)(2) currently provides in part that an authorized user of strontium-90 for ophthalmic radiotherapy must have completed supervised clinical training under the supervision of an authorized user at a medical institution that includes the use of strontium-90 for the ophthalmic treatment of five individuals. This current requirement unnecessarily excludes authorized users at eye clinics and private practices from being allowed to provide training. This restriction should be eliminated because many authorized users for ophthalmic treatment work in clinics or private practices. This section is therefore revised to add “clinic or private practice” to “medical institution” as acceptable locations where the requisite supervised clinical training may be provided.
(8) Section 35.630. Paragraph (a)(1) states: “The system must have been calibrated using a system or source traceable to the National Institute of Science and Technology (NIST) and * * *.” The title of NIST is “National Institute of Standards and Technology.” Thus, the word “Science” is replaced by the word “Standards.”
(9) Section 35.2432, Records of calibration measurements of brachytherapy sources. This section provides that a licensee must maintain a record of the calibration of brachytherapy sources required by § 35.432. Paragraph 35.2432(b)(5) requires that the record must include the signature of the authorized medical physicist (AMP). Section 35.432, Calibration measurements of brachytherapy sources, requires that a licensee shall have a brachytherapy source calibrated or the licensee may use measurements provided by the source manufacturer or by a calibration laboratory. However, § 35.432 does not specify that an AMP must perform the calibration. Thus, it is inconsistent to require a record of the signature of the AMP in § 35.2432 without a Start Printed Page 19323requirement for the AMP to perform the calibration in § 35.432.
In the proposed rule (63 FR 43516; August 13, 1998), § 35.2432 would have provided that the record of calibration must contain “the name of the individual or the source manufacturer who performed the calibration.” This language was consistent with the language of proposed § 35.432.
In the final rule, (67 FR 20249; April 24, 2002), § 35.432 was changed from that in the proposed rule to allow the licensee to rely on measurements provided by a calibration laboratory, in addition to those provided by a manufacturer. The language in § 35.2432 was also changed but was not consistent with § 35.432.
The Supplementary Information to the final rule includes a discussion of the changes made to § 35.2432 between the proposed rule and the final rule. That discussion does not include any rationale for changing the proposed rule language requiring “the name of the individual or the source manufacturer who performed the calibration” to the final rule language requiring “the signature of the authorized medical physicist.” Section 35.2432(b)(5) is therefore modified to replace the phrase “the signature of the authorized medical physicist” with the phrase “the name of the individual, the source manufacturer, or the calibration laboratory who performed the calibration.” This modification resolves inconsistency between § 35.2432 and § 35.432.
Under the “Policy Statement on Adequacy and Compatibility of Agreement State Programs” approved by the Commission on June 30, 1997, and published in the Federal Register on September 3, 1997 (62 FR 46517), this direct final rule is a matter of compatibility between NRC and the Agreement States, thereby providing consistency among Agreement State and NRC requirements. A Compatibility Category “B” designation means the requirement has significant direct transboundary implications. Compatibility Category “B” designated Agreement State requirements should be essentially identical to those of NRC. A Compatibility Category “D” designation means the requirement does not need to be adopted by an Agreement State for purposes of compatibility. The Compatibility Category Health and Safety (H&S) identifies requirements that are not required for compatibility, but which have particular health and safety significance. Agreement States should adopt the essential objectives of such requirements in order to maintain an adequate program.
The Compatibility Categories for the sections amended in this direct final rule are the same as the sections in the current regulations. The revisions to §§ 35.2, 35.51, 35.190, 35.290, 35.390, 35.392, 35.394, 35.490, 35.491, and 35.690 are classified as Category B. The revisions to §§ 35.100, 35.200, 35.300, 35.310(a), 35.315, and 35.630 are classified as Category H&S. The revision to § 35.2432 is classified as Category D.
The National Technology Transfer Act of 1995 (Pub. L. 104-113) requires that Federal agencies use technical standards that are developed or adopted by voluntary consensus standards bodies unless the use of such a standard is inconsistent with applicable law or otherwise impractical. In this direct final rule, NRC is amending 10 CFR part 35 to clarify certain inconsistencies with the regulations and to allow training in ophthalmic treatment to be conducted in eye clinics or private practices, in addition to medical institutions. This action does not constitute the establishment of a standard that establishes generally-applicable requirements.
The Commission has determined that this direct final rule is the type of action described in categorical exclusion 10 CFR 51.22(c)(2). Therefore, neither an environmental impact statement nor an environmental assessment has been prepared for this direct final rule.
This direct final rule does not contain a new or amended information collection requirement subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). However, the rule makes a technical change to correct an error in a record requirement that appeared in the Part 35 final rule. Existing requirements were approved by the Office of Management and Budget, approval number 3150-0010.
A regulatory analysis has not been prepared for this direct final rule. The clarifying amendments are for ease of understanding of certain aspects of part 35. The minor amendment on ophthalmic treatment is to provide flexibility that clinical training can be conducted under supervision of an authorized user in clinics or private practices, in addition to medical institutions. This flexibility could potentially result in a small reduction in burden for an individual who is undertaking the clinic training.
In accordance with the Regulatory Flexibility Act of 1980, 5 U.S.C. 605(b), NRC certifies that this rule will not, if promulgated, have a significant economic impact on a substantial number of small entities. This direct final rule simply amends present regulations to clarify certain inconsistencies with the regulations and to allow training in ophthalmic treatment to be conducted in eye clinics or private practices, in addition to medical institutions. The companies that own these facilities do not fall within the scope of the definition of “small entities” set forth in the Regulatory Flexibility Act or the size standards adopted by NRC (10 CFR 2.810).
NRC has determined that the backfit rule does not apply to this direct final rule because these amendments do not involve any provisions that would impose backfits as defined in 10 CFR Chapter 1.
In accordance with the Small Business Regulatory Enforcement Fairness Act of 1996, NRC has determined that this action is not a major rule and has verified this determination with the Office of Information and Regulatory Affairs, Office of Management and Budget.
For reasons set out in the preamble and under the authority of the Atomic Energy Act of 1954, as amended; the Energy Reorganization Act of 1974, as amended; and 5 U.S.C. 552 and 553; NRC is adopting the following amendments to 10 CFR part 35.
