FINAL SUPPORTING STATEMENT

FOR

10 CFR PART 35

MEDICAL USE OF BYPRODUCT MATERIAL

(3150-0010)

CLEARANCE EXTENSION WITH BURDEN REVISION

Part 35 of Title 10 of the Code of Federal Regulations contains the Nuclear Regulatory Commission's requirements and provisions for the medical use of byproduct material and for issuance of specific licenses authorizing the medical use of this material. These requirements and provisions provide for the radiation safety of workers, the general public, patients, and human research subjects.

The recordkeeping and most of the reporting requirements of Part 35 are centralized into two Subparts: Subpart L - Records (§§ 35.2024-2655) and Subpart M - Reports (§§ 35.3045-3067). Cross references to the recordkeeping requirements in Subpart L appear in other related portions of the Part 35 rule, but these cross references do not constitute additional recordkeeping requirements.

The burden for the training and experience requirements in Subparts B and D-H are related as appropriate to the clearance for NRC Form 313, "Application for Material License," and to the NRC Form 313A series of forms for individuals seeking authorization for recognition as authorized users (AU), authorized medical physicists (AMP), authorized nuclear pharmacists (ANP), and radiation safety officers (RSO); which are cleared under OMB Clearance No. 3150-0120. Subsequent references to "NRC Form 313" are intended to refer to NRC Form 313 and to the NRC Form 313A series of forms for recognition as AU, AMP, ANP, and RSO.

A. Justification

NRC regulates and licenses the medical use of byproduct materials, as provided by the Atomic Energy Act (AEA) as amended, and the Energy Reorganization Act of 1974, in order to provide for the radiation safety of workers, the general public, and patients. Licensees must perform certain tasks, maintain records, and prepare reports to demonstrate their fulfillment of regulatory requirements. The records required by Part 35 are the least burdensome way for licensees to demonstrate compliance with the NRC's requirements. However, certain events are of such significance that they must be reported to the NRC, to patients or human research subjects, and to referring physicians. Collection of this information enables the NRC to determine what steps must be taken by other licensees to prevent such events, whether required notifications have been made, and whether corrective actions have been taken. In addition, NRC has the responsibility, pursuant to section 208 of the Energy Reorganization Act of 1974, as amended, to inform Congress and the public of those events constituting "abnormal occurrences" and to also inform NRC medical use licensees of generic issues identified by the NRC review of medical events.

1. Need for and Practical Utility of the Collection of Information

§ 35.6 Provisions for the protection of human research subjects

This section requires a licensee whose research is conducted, funded, supported, or regulated by another Federal agency that has implemented the Federal Policy for the Protection of Human Subjects, prior to conducting research, to obtain review and approval of the research by an “Institutional Review Board (IRB),” as defined and described in the Federal Policy and obtain “informed consent” from the human research subject. This review and approval is needed to ensure the licensee’s compliance with the requirements for the protection of human subjects. Informed consent is needed to ensure that the human research subject is informed of any potential risks and voluntarily agrees to them.

This section also requires a licensee whose research is not conducted, funded, supported, or regulated by another Federal Agency which has implemented the Federal Policy for the Protection of Human Subjects to apply for and receive approval of a specific amendment to its NRC medical use license before conducting such research. The amendment request must include a written commitment that the licensee will, prior to conducting research: (1) obtain review and approval of the research by an “Institutional Review Board,” as defined and described in the Federal Policy; and (2) obtain “informed consent,” as defined and described in the Federal Policy, from the human research subject. This information is needed to ensure the licensee's compliance with the requirements for the protection of human subjects.

§ 35.12 Application for license, amendment, or renewal

Paragraph 35.12(b) requires that an application for a license for medical use of byproduct material as described in §§ 35.100, 35.200, 35.300, 35.400, 35.500, 35.600, and 35.1000 must be made by filing an original and one copy of NRC Form 313, "Application for Material License." This includes the facility diagram, equipment, and training and experience qualifications of the Radiation Safety Officer, authorized user(s), authorized medical physicist(s), and authorized nuclear pharmacist(s); and submitting procedures required by §§  35.610, 35.642, 35.643, and 35.645, as applicable. NRC Form 313 requires a description of the applicant’s complete radiation safety program. Under § 35.12(c), an application for license amendment or renewal must be made on NRC Form 313 or by a letter requesting the amendment or renewal, and must include procedures required by §§ 35.610, 35.642, 35.643, and 35.645, as applicable. An application must be signed by the applicant’s or licensee’s management.

The burden for Paragraphs 35.12 (b) and (c) is cleared under OMB Clearance No. 3150-0120, which should be referred to for additional supporting information, burden and cost data.

Paragraph 35.12(d), in addition to the requirements in paragraphs (b) and (c) of this section, requires that an application for a license or amendment for medical use of byproduct material as described in § 35.1000 must also include information regarding any radiation safety aspects of the medical use of the material that is not addressed in the requirements of Subparts A through C of this part. The applicant also is required to provide specific information on: (1) radiation safety precautions and instructions; (2) methodology for measurement of dosages or doses to be administered to patients or human research subjects; and (3) calibration, maintenance, and repair of instruments and equipment necessary for radiation safety. The applicant or licensee also is required to provide any other information requested by the Commission in its review of the application. This information is needed to enable the Commission to evaluate a license application for a new medical use of byproduct material that is not specifically addressed in subparts D through H of Part 35. The burden for new modalities is submitted on NRC Form 313 (OMB Clearance No. 3150-0120).

§ 35.13 License amendments

This section requires that licensees apply for and receive a license amendment before receiving, preparing, or using byproduct material for medical uses that are permitted under Part 35, but are not authorized by the licensee's current license issued under this part; before permitting anyone to work as an authorized user, authorized nuclear pharmacist, or authorized medical physicist under the license, except as provided in § 35.14(a); before changing Radiation Safety Officers (RSO), except as provided in § 35.24(c); before receiving byproduct material in excess of the amount or in a different form than is authorized on the license, or receiving a different radionuclide than is authorized on the license; before adding or otherwise changing areas of use identified in the application or on the license including areas used in accordance with §§ 35.100 and 35.200 if the change includes addition or relocation of either an area where PET radionuclides are produced or a PET radioactive delivery line from a PET radionuclide/PET radioactive drug production area (other areas of use where byproduct material is used only in accordance with §§ 35.100 and 35.200 are exempt) before changing the address(es) of use identified in the application or on the license, and before revising procedures required by §§ 35.610, 35.642, 35.643, and 35.645, as applicable, where such revision reduces radiation safety. The information is necessary to determine the licensee's ability to control radiation dose to workers, patients, and the public; and for NRC to contact the licensee or conduct an inspection of the licensee's program. The information also is required so that the NRC can determine whether the licensee has individuals with adequate training and experience to use byproduct material safely, and has the facilities and equipment necessary to ensure protection of public health and safety.

The burden for Section 35.13 is included in the information collection burden for NRC Form 313 (OMB Clearance No. 3150-0120).

§ 35.14 Notifications

Paragraph 35.14(a) requires that licensees provide to the Commission a copy of the board certification and written attestation, the Commission or Agreement State license, the permit issued by an NRC master material licensee, the permit issued by a licensee of broad scope, or the permit issued by an NRC master material license broad scope permit for each individual no later than 30 days after the date the licensee permits the individual to work as an authorized user (AU), as an authorized nuclear pharmacist (ANP), or as an authorized medical physicist (AMP). The information is required so that the NRC can determine whether the licensee has individuals with adequate training and experience to use byproduct material safely.

Paragraph 35.14(b) requires that licensees notify the NRC by letter no later than 30 days after an ANP, AU, AMP, or RSO permanently discontinues performance of duties under the license or has a name change; when the licensee's mailing address changes; when the licensee has a name change that is not a transfer of control of the license; or when licensees authorized for use of byproduct material under §§ 35.100 and 35.200 have added to or changed the areas of use identified in the application or on the license, if the change does not include addition or relocation of either an area where PET radionuclides are produced or a PET radioactive drug delivery line from the PET radionuclide/PET radioactive drug production area. The report for AU and ANP is required in order to maintain the license file with a current record of individuals authorized to use or prepare byproduct material. The report for changes in "key" workers is required because, if the licensee no longer has a complete staff, the collective training and experience of the remaining staff may no longer be sufficient to ensure the safety of all licensed uses. This report will trigger a check of the licensee's file to determine whether the licensee's remaining users are qualified to receive and use byproduct material safely. The NRC needs to be aware of name and mailing address changes to ensure that the licensee continues receiving correspondence such as information notices, bulletins, and other safety related documents. The NRC needs to be aware of changes of areas of use so that NRC can determine if the facilities are adequate to assure protection of public health and safety.

§ 35.19 Specific exemptions

Section 35.19 provides that upon application of any interested person or upon its own initiative, the Commission may grant exemptions from the regulations in Part 35 that it determines are authorized by law and will not endanger life or property or the common defense and security and are otherwise in the public interest. Applications for and granting of specific exemptions will allow NRC to make provision for special circumstances outside the purview of the regulations.

§ 35.24 Authority and responsibilities for the radiation protection program

Paragraph 35.24(a) requires a licensee's management to approve in writing (1) requests for license application, renewal, or amendment prior to submittal; (2) any individual, prior to allowing that individual to work as an authorized user, authorized nuclear pharmacist, or authorized medical physicist; and (3) radiation protection program changes that do not require an amendment and are permitted under § 35.26. Management approval is necessary to ensure that actions affecting the radiation protection program have been reviewed by responsible licensee officials.

Paragraph 35.24(b) requires a licensee’s management to appoint a Radiation Safety Officer, who agrees in writing to be responsible for implementing the radiation protection program. The written agreement from the Radiation Safety Officer (including temporary Radiation Safety Officers) is needed to record the acceptance by the Radiation Safety Officer of all of the obligations of the post.

A licensee may permit an authorized user or an individual qualified to be a Radiation Safety Officer to function as a temporary Radiation Safety Officer, and a licensee may simultaneously appoint more than one temporary Radiation Safety Officer. Paragraph 35.24(c) requires a licensee that appoints a temporary Radiation Safety Officer to notify the Commission in accordance with § 35.14(b). The report of temporary Radiation Safety Officers is required because a licensee may permit an authorized user or an individual qualified to be a Radiation Safety Officer to function as a temporary Radiation Safety Officer only for up to 60 days each year.

Paragraph 35.24(e) requires a licensee to establish in writing the authority, duties, and responsibilities of the Radiation Safety Officer, so that the duties and responsibilities of the Radiation Safety Officer are clearly defined, and the Radiation Safety Officer is provided sufficient authority to assure that the licensee's radiation safety activities are being performed in accordance with regulatory requirements.

Paragraph 35.24(f) requires licensees who are authorized for two or more different types of uses of byproduct material under Subparts E, F, and H, or two or more types of units under Subpart H, to establish a Radiation Safety Committee to oversee all uses of byproduct material permitted by the license. The requirement to establish a Radiation Safety Committee to oversee the radiation protection program provides assurance both to the licensees and to NRC that all of the different departments and diverse professional staff are aware of changes, needs, and issues related to the licensee's radiation protection program.

Paragraph 35.24(h) requires that a record of actions taken pursuant to paragraphs (a), (b) and (e) be retained in accordance with § 35.2024. A description of the contents of the record and the need for the record is provided under § 35.2024.

§ 35.26 Radiation protection program changes

Paragraph 35.26(a) allows a licensee to revise its radiation protection program without Commission approval if the revision does not require an amendment under § 35.13; the revision is in compliance with the regulations and the license; the revision has been reviewed and approved by the Radiation Safety Officer and licensee management; and the affected individuals are instructed on the revised program before the changes are implemented. Review and approval by licensee management will allow a licensee to make some changes in their radiation safety program, provided that the changes are in compliance with the regulations and the license.

Paragraph 35.26(b) requires a record of each change to be retained in accordance with

§ 35.2026. A description of the contents of the record and the need for the record is provided under § 35.2026.

§ 35.27 Supervision

Paragraph 35.27(a) requires a licensee that permits the receipt, possession, use, or transfer of byproduct material by an individual under the supervision of an authorized user as allowed by § 35.11(b) to instruct the supervised individual in the licensee's written radiation protection procedures, written directive procedures, Part 35 regulations, and license conditions with respect to the use of byproduct material. This instruction is necessary to provide high confidence that the supervised individual knows and follows all of these procedures, regulations, and license conditions.

Paragraph 35.27(b) requires a licensee that permits the preparation of byproduct material for medical use by an individual under the supervision of an authorized nuclear pharmacist or physician who is an authorized user as allowed by § 35.11(b)(2) to instruct the supervised individual in the preparation of byproduct material for medical use and require the supervised individual to follow the instructions of the supervising authorized user or authorized nuclear pharmacist regarding the preparation of byproduct material for medical use, radiation protection procedures, Part 35 regulations, and license conditions. This instruction is necessary to provide high confidence that the supervised individual properly prepares byproduct material for medical use.

§ 35.40 Written directives

Paragraph 35.40(a) requires licensees that perform certain specified medical administrations involving I-131 sodium iodide greater than 1.11 Megabequerels (MBq), any therapeutic dosage of unsealed byproduct material, or any therapeutic dose of radiation from byproduct material, to prepare a dated and signed written directive prior to performing the medical administration.

The regulatory text of § 35.40(b) requires:

(b) The written directive must contain the patient or human research subject’s name and the following information—

1. For any administration of quantities greater than 1.11 MBq (30 μCi)

of sodium iodide I-131: the dosage;

(2) For an administration of a therapeutic dosage of unsealed byproduct material other than sodium iodide I-131: the radioactive drug, dosage, and route of administration;

(3) For gamma stereotactic radiosurgery: the total dose, treatment site, and values for the target coordinate settings per treatment for each anatomically distinct treatment site;

(4) For teletherapy: the total dose, dose per fraction, number of fractions, and treatment site;

(5) For high dose-rate remote afterloading brachytherapy: the radionuclide, treatment site, dose per fraction, number of fractions, and total dose; or

(6) For all other brachytherapy, including low, medium, and pulsed dose rate remote afterloaders:

(i) Before implantation: treatment site, the radionuclide, and dose; and

(ii) After implantation but before completion of the procedure: the radionuclide, treatment site, number of sources, and total source strength and exposure time (or the total dose).

If an oral directive is used because of the emergent nature of the patient’s condition, subsection 35.40(a)(1) requires the information in the oral directive to be documented as soon as possible in writing in the patient’s record and a written directive must be prepared within 48 hours of the oral directive. Documenting an oral directive is needed to ensure that complete record is made of the administration of byproduct material or radiation from byproduct material.

Paragraph 35.40(c) permits a written revision to an existing written directive if the revision is dated and signed by an authorized user before the administration or the next fractional dose. If an oral revision to an existing written directive is used because of the emergent nature of the patient’s condition, the oral revision must be documented as soon as possible in the patient’s record and a revised written directive must be signed by the authorized user within 48 hours of the oral revision. Documenting an oral directive is needed to ensure that complete record is made of the administration of byproduct material or radiation from byproduct material.

Paragraph 35.40(d) requires the licensee to retain a copy of the written directive in accordance with § 35.2040. A description of the record and the need for the record is provided under § 35.2040. Preparation of a written directive is necessary to provide high confidence that byproduct material will be administered as directed by the authorized user physician.

§ 35.41 Procedures for administrations requiring a written directive

Paragraph 35.41(a) requires licensees to develop, implement and maintain written procedures for any administration requiring a written directive to provide high confidence that the patient or human research subject's identity is verified prior to each administration and that each administration is in accordance with the written directive. These procedures are necessary to ensure that administrations that require a written directive are given as directed by the authorized user physician.

Paragraph 35.41(c) requires the licensee to retain a copy of the procedures required by § 35.41(a) in accordance with § 35.2041. A description of the record and the need for the record is provided under § 35.2041.

Paragraph 35.3045(a) requires licensees to report any event, except for an event that results from patient intervention, in which the administration of byproduct material or radiation from byproduct material results in a dose meeting or exceeding specified criteria. The burden associated with this paragraph is addressed under paragraphs (c) and (d) of this section.

Paragraph 35.3045(b) requires licensees to report any event resulting from intervention of a patient or human research subject in which the administration of byproduct material or radiation from byproduct material results or will result in unintended permanent functional damage to an organ or a physiological system, as determined by a physician. The burden associated with this paragraph is addressed under paragraphs (c) and (d) of this section.

Paragraph 35.3045(c) requires licensees to notify NRC by telephone no later than the next calendar day after discovery of the medical event. This reporting requirement is needed to ensure that NRC is aware of medical events and is able promptly to take any necessary actions based on the circumstances.

Paragraph 35.3045(d) requires licensees to submit a written report to NRC within 15 days of the discovery of the medical event. The report must include the licensee's name; the name of the prescribing physician; a brief description of the event; why the event occurred; the effect, if any, on the individual(s) who received the administration; what actions, if any, have been taken or are planned to prevent recurrence; certification that the licensee notified the individual (or the individual's responsible relative or guardian) and if not, why not. The report must not contain the individual's name or any other information that could lead to identification of the individual. This reporting requirement is needed to provide NRC a synopsis of the event, its cause(s), and corrective actions taken, so that NRC can ensure that appropriate follow-up actions are taken after medical events, and so that NRC can promptly notify other licensees if it appears the precipitating event might be generic.

Paragraph 35.3045(e) requires the licensee to notify the referring physician and the individual who is the subject of the medical event, or that individual's responsible relative or guardian, no later than 24 hours after its discovery, or as soon as possible, if the patient or the referring physician cannot be reached within 24 hours. Patients and their referring physician(s) need this information to make timely decisions regarding possible health care needs. If verbal notification is made, the licensee is required to inform the individual or responsible relative or guardian that a written description of the event may be obtained upon request. The licensee shall provide such a written description, if requested.

Paragraph 35.3045(g) requires the licensee to: (1) annotate a copy of the medical event report provided to the NRC with the: (a) name of the individual who is the subject of the event; and (b) social security number or other identification number, if one has been assigned, of the individual who is the subject of the event; and (2) provide a copy of the annotated report to the referring physician, if other than the licensee, no later than 15 days after the discovery of the event. It is necessary to annotate the report to the NRC because the report has no identifying information regarding the patient. It is necessary to send a copy of the annotated report to the referring physician because the referring physician is responsible for the medical care of the patient and this information is needed for the physician to care for the patient.

§ 35.3047 Report and notification of a dose to an embryo/fetus or a nursing child

Paragraph 35.3047(a) requires the licensee to report any dose to an embryo/fetus that is greater than 50 mSv (5 rem) dose equivalent that is the result of an administration of byproduct material or radiation from byproduct material to a pregnant individual unless the dose to the embryo/fetus was specifically approved, in advance, by the authorized user. The burden for this requirement is addressed under paragraphs (c) and (d) of this section. This report is needed so that NRC can comply with the legislative intent of section 208 of the Energy Reorganization Act of 1974 (Public Law 93-438) as amended, which requires NRC to submit reports to Congress of unintended radiation exposure.

Paragraph 35.3047(b) requires the licensee to report any dose to a nursing child that is greater than 50 mSv (5 rem) total effective dose equivalent or has resulted in unintended permanent functional damage to an organ or a physiological system of the child, as determined by a physician, that is a result of an administration of byproduct material to a breast-feeding individual. The burden for this requirement is addressed under paragraphs (c) and (d) of this section. This report is needed so that NRC can comply with the legislative intent of section 208 of the Energy Reorganization Act of 1974 (Public Law 93-438) as amended, which requires NRC to submit to Congress reports of unintended radiation exposure.

Paragraph 35.3047(c) requires the licensee to notify by telephone the NRC Operation Center no later than the next calendar day after discovery of a dose to the embryo/fetus or nursing child that requires a report under § 35.3047(a) or (b). This reporting requirement is needed to ensure that NRC is aware of unintended radiation exposure to an embryo/fetus or nursing child and can promptly take any necessary actions based on the circumstances.

Paragraph 35.3047(d) requires the licensee to submit a written report to the appropriate NRC Regional Office no later than 15 days after discovery of a dose to the embryo/fetus or nursing child that requires a report under § 35.3047(a) or (b). The written report must include the licensee's name; the name of the prescribing physician; a brief description of the event; why the event occurred; the effect, if any, on the embryo/fetus or the nursing child; what actions, if any, have been taken or are planned to prevent recurrence; and certification that the licensee notified the pregnant individual or mother (or the mother’s or child’s responsible relative or guardian, and if not, why not. The report must not contain the individual's or child’s name or any other information that could lead to identification of the individual or child. This reporting requirement is needed to provide information to NRC about the causes of the unintended radiation exposure to an embryo/fetus or nursing child and methods to prevent recurrence.

Paragraph 35.3047(e) requires the licensee to notify the referring physician and also notify the pregnant individual or mother (both hereafter referred to as the mother) no later than 24 hours after discovery of an event that would require reporting under paragraph (a) or (b) of this section, unless the referring physician personally informs the licensee either that he or she will inform the mother or that, based on medical judgment, telling the mother would be harmful. If the referring physician or mother cannot be reached within 24 hours, the licensee is required to make the appropriate notifications as soon as possible thereafter. To meet the requirements of this paragraph, the notification may be made to the mother’s or child’s responsible relative or guardian instead of the mother, when appropriate. If a verbal notification is made, the licensee shall inform the mother, or the mother’s or child’s responsible relative or guardian that a written description of the event can be obtained from the licensee upon request. The licensee shall provide such written description if requested. This reporting requirement is needed to provide information about the event to the referring physician and the pregnant individual or mother, or the mothers or child’s responsible relative or guardian, for appropriate medical care, if needed.

Paragraph 35.3047(f) requires the licensee to: (1) annotate a copy of the report provided to the NRC with the: (a) name of the pregnant individual or the nursing child who is the subject of the event; and (b) social security number or other identification number, if one has been assigned, of the pregnant individual or the nursing child who is the subject of the event; and (2) provide a copy of the annotated report to the referring physician, if other than the licensee, no later than 15 days after the discovery of the event.

§ 35.3067 Report of a leaking source

This section requires licensees to report detection of a leaking source by submitting a written report within 5 days after a leakage test required by § 35.67 reveal the presence of 185 Bq (0.005 microcurie) or more of removable contamination. The report must be filed with the appropriate NRC Regional Office with a copy to the NRC Headquarters Office. The report must include the model and serial number, if assigned, of the leaking source; the radionuclide and its estimated activity; the results of the test, the date of the test, and the action taken. This report is needed to ensure that the NRC is aware of the leaking source and is able promptly to take any necessary actions based on the circumstances.

2. Agency Use of Information

The NRC uses the records and reports required in this part to ascertain that licensees' medical use programs are adequate to protect public health and minimize danger to life and property and that licensees' personnel are aware of and follow up on the information and steps needed to perform licensed activities in a safe manner. The staff makes use of the records and reports to determine whether the licensee has individuals with adequate training and experience to safely use byproduct material or radiation from byproduct material to be administered to patients or human research subjects, and has the facilities and equipment necessary to assure protection of public health and safety. NRC also uses the information to develop reports to inform Congress and the public about the measures taken to provide for the radiation safety of workers, the general public, and patients, and to alert licensees to issues of general concern. Reports of medical events are required to ensure that NRC is notified of significant events. These reports also allow NRC to determine whether to take actions, such as to conduct inspections, or to alert other medical use licensees, to prevent similar events that may have generic implications. In addition, collection of this information enables the NRC to ascertain whether such events are evaluated by the licensee, reported to patients or human research subjects, and referring physicians and that corrective action is taken.

3. Reduction of Burden Through Information Technology

There are no legal obstacles to reducing the burden associated with this information collection. The NRC encourages respondent to use information technology when it would be beneficial to them. NRC issued a regulation on October 10, 2003 (68 FR 58791), consistent with the Government Paperwork Elimination Act, which allows its licensees, vendors, applicants, and members of the public the option to make submissions electronically via CD-ROM, e-mail, special Web-based interface, or other means. Currently, no responses are filed electronically.

4. Effort to Identify Duplication and Use Similar Information

No sources of similar information are available. There is no duplication of requirements. NRC has in place an ongoing program to examine all information collections with the goal of eliminating all duplication and/or unnecessary information collections.

5. Effort to Reduce Small Business Burden

While a number of medical licensees are considered small businesses under the NRC's current definitions, the health and safety consequences of improper use of byproduct material are the same for large and small entities. It is not possible to reduce the burden on small businesses by less frequent or less complete reporting, recordkeeping, or accounting and control procedures while maintaining the required level of safety.

6. Consequences to Federal Program or Policy Activities if the Collection is Not Conducted or is Conducted Less Frequently

If the information is not collected, NRC will not be in a position to assess whether this category of licensee is operating within the specific radiation safety requirements applicable to the medical use, possession, or transfer of byproduct material for medical use. In addition, NRC will not be able to report to Congress and evaluate those medical events constituting "abnormal occurrences" or to ensure that patients, human research subjects, and referring physicians are informed of "medical events."

Applications are required to be submitted for the initial license, for amendments, and for renewals. The review and submission of the information required for the application is essential to NRC's determination of whether the applicant has adequate training, experience, equipment, and facilities to protect the public health and safety. Other reporting and recordkeeping requirements apply to specific actions or events (e.g., inventories of licensed material, calibrations and checks of medical devices and medical events). Collection of specific information at the required frequency from licensees that administer byproduct material to patients or human research subjects is essential to protect the health and safety of workers, patients and human research subjects, and the public.

7. Circumstances Which Justify Variation from OMB Guidelines

Contrary to OMB’s implementing regulation at 5 CFR 1320.5(d), some of the provisions in the revision of Part 35 require licensees to maintain records for more than three years or to report information to the NRC or to patients’ physicians within less than 30 days following an occurrence.

Paragraph 35.67(e)(2) requires that, in accordance with § 35.3067, a licensee file a report within five days if a leakage test reveals the presence of 185 Bq (0.005 microcuries) or more of removable contamination. This report is necessary so that the NRC can make a determination as to whether other licensees who have similar sealed sources should take special precautions and to promptly notify other licensees if it appears there may be a generic problem. NRC allows the licensee up to five days to submit the report so that the licensee can review and analyze the leak test result.

Paragraph 35.642(c) requires that an authorized medical physicist review the results of each spot-check of a teletherapy unit and notify the licensee as soon as possible in writing of the results of each spot-check.

Section 35.2652 requires that a record of radiation surveys of treatment units made in accordance with § 35.652 be retained for the duration of use of the unit to provide assurance that the source was properly installed or repaired and that the unit did not exceed occupational dose levels with the sources in the shielded position. These records also would be necessary in reconstructing the contributing factors following an incident involving the unit.

Section 35.2655 requires that a record of five-year inspections for teletherapy and gamma stereotactic radiosurgery units required by § 35.655 be retained for the duration of use of the unit. This record is required throughout the period of use of the unit to show that the required work was done and to establish a service history that may be used in incident investigations and evaluation of generic equipment problems.

Paragraph 35.3045(d) requires that licensees submit a written report to the appropriate NRC Regional Office listed in § 30.6 within 15 calendar days after discovery of a medical event. This requirement balances the time required for the licensee to evaluate the event and prepare a written report against the needs of the NRC to take timely action, as necessary, to address the medical event.

Paragraph 35.3045(e) requires that if an individual affected by a medical event has been notified verbally about the medical event, the licensee must furnish a written report of the medical event to the individual upon request. This requirement ensures that complete written information will be furnished to an individual upon request so that adequate follow-up medical care can be provided, if needed.

Paragraph 35.3045(g) requires a licensee to provide a copy of the annotated medical event report to the referring physician, if other than the licensee, no later than 15 days after the discovery of the event. This requirement balances the time required for the licensee to evaluate the event and prepare a written report against the needs of the referring physician to provide timely follow-up medical care, if needed.

The grand total of the burden for Part 35 is 1,173,785 hours (156,538 + 1,017,247). The total cost for Part 35 is 301,662,745 (1,173,785 x $257/hr).

The number of NRC recordkeepers (1,148) is taken from the LTS and master materials licensee database. The Agreement State recordkeeper (7,462) is derived from multiplying the number of NRC medical use licenses by the ratio of all NRC materials licenses and all Agreement State material licenses. This ratio is 6.5.

Total Responses for NRC and Agreement States licenses are as follows: 246,581 ((NRC:  31,732 + 1,148 recordkeepers = 32,880) + (Agreement States: 206,239 + 7,462 recordkeepers = 213,701)).

13. Estimate of Other Additional Costs

The NRC has determined that the quantity of records to be maintained is roughly proportional to the recordkeeping burden and, therefore, can be used to calculate approximate records storage costs. Based on the number of pages maintained for a typical clearance, the records storage cost has been determined to be equal to 0.0004 times the recordkeeping burden cost. Because the recordkeeping burden is estimated to be 1,114,685 hours, the storage cost for this clearance is $ 114,590 (1,114,685 X 0.0004 X $257).

14. Estimated Annualized Cost to the Federal Government

For the requested clearance period, the annualized burden and cost to NRC staff for review of submittals made under Part 35 is estimated to be 300 hours and $77,100 ($257 per hour x 300 hours). This estimate includes the recurring burden of 300 hours to review event reports. This cost is fully recovered through fee assessments to NRC licensees pursuant to 10 CFR Parts 170 and 171.

15. Reasons for Changes in Burden

Although the overall burden has increased by 147,827 hours from 1,025,958 (259,513 NRC Licensees + 766,445 Agreement States) to 1,173,785 hours (NRC Licensees 156,536 hrs + Agreement States 1,017,245 hrs), the number of responses decreased by 14,813 responses from 261,394 responses (55,629 NRC Licensees + 205,765 Agreement States) to 246,581 responses (32,880 NRC Licensees + 213,701 Agreement States). The burden calculations were affected by (1) a correction for medical event reporting based on the actual number of medical events reported per year, (2) an increase in the number of Agreement States, and (3) a shift in the distribution of medical uses by the remaining NRC licensees.

Approximately 38 medical events are reported each year by both NRC and Agreement State licensees instead of the previously estimated 164. This correction resulted in a burden reduction of 995 hours (327 hours for NRC licensees and 668 hours for the Agreement State licensees). Three states (Pennsylvania, Virginia and New Jersey) entered into agreements with NRC since 2007. NRC now has fewer licensees then in 2007 and the Agreement States have more. This accounts for a marked decrease in burden for NRC licensees and a marked increased shift in burden to the Agreement States.

NRC calculates the burden for Agreement State medical use licensees based on the ratio of NRC licensees to Agreement State licensees, ratio of remaining medical use licensees to NRC licensees, and distribution of the types of medical uses retained by NRC medical licensees. The result is an estimated decrease in the total number of NRC and Agreement State medical use licensees from 8,751 to 8,610 and a shift in the types of medical uses retained by NRC

licensees to those medical uses with larger calculated record keeping burdens. For example, NRC lost approximately one third of its medical use licensees but approximately one half of its brachytherapy, gamma sterotactic radiosurgery and remote afterloader use licensees which because of lower patient loads have fewer record keeping burdens. At this time, NRC cannot determine whether the resulting calculations for the Agreement State licensee are less or more accurate.
