FINAL OMB SUPPORTING STATEMENT FOR

10 CFR PART 39

LICENSES AND RADIATION SAFETY REQUIREMENTS FOR WELL LOGGING

(3150-0130)

---

EXTENSION

Description of the Information Collection

U.S. Nuclear Regulatory Commission (NRC) regulations in Title 10 of the Code of Federal Regulations (10 CFR) Part 39 establish rules that specify radiation safety requirements for the issuance of licenses for the use of sealed sources containing byproduct material and radiation safety requirements for persons using these sealed sources in well logging operations.

The requirements in Part 39 specify what information must be submitted in an application for a license to conduct well logging operations, including, for example, the applicant’s program for training logging supervisors and logging assistants, written operating and emergency procedures, and a description of the applicant's organizational structure as it applies to the radiation safety responsibilities in well logging.

The information required by Part 39 is collected because it is necessary to ensure that an applicant for a license to conduct well logging operations is properly qualified to perform this activity, and to ensure the safety of employees and members of the public. The regulations provide for comprehensive and consistent radiation safety requirements in NRC and Agreement State regulations, and safety requirements designed to reduce the likelihood of accidents involving radioactive sources in well logging operations.

Persons affected by the information collection requirements of Part 39 include applicants for, and holders of, NRC and Agreement State licenses to conduct well logging operations.

1. Justification

1. Need For the Collection of Information 

See Appendix A- Description of Information Collection Requirements for 10 CFR Part 39

2. Agency Use of the Information

The records that Part 39 requires licensees to maintain are reviewed by the NRC staff during inspections, license renewals, and license amendment reviews to evaluate compliance with NRC radiation safety requirements for possession and use of licensed radioactive material in well logging.

For example, internal inspection records are reviewed by NRC inspectors to verify that the licensee is maintaining and implementing an effective inspection program and that safety related issues are being identified and corrected. A written agreement between the licensee performing well logging and with a well owner or operator is necessary to ensure that recovery or abandonment procedures will be implemented in the event of a stuck or irretrievable well logging source. The identification plaque is necessary to provide a warning to anyone attempting to re-enter the well of the presence of the abandoned source and to provide information on the source and its location within the well. Labels required on the source, the source holder, or the logging tool containing radioactive materials, and the storage or transport container, are needed to warn people that these devices or containers contain radioactive materials and that persons should notify civil authorities or the company if a labeled device or container is found.

Calibration records are needed to permit NRC inspectors to verify that the licensee is keeping calibrated and operable radiation survey instrument(s) at each field station and temporary job site to make required radiation surveys. Similarly, records of the results of leak testing of sealed sources are reviewed by NRC inspectors to verify that licensees have the source tested for leakage at least every 6 months, to ensure the sealed sources maintain their integrity.

The required reports regarding ruptured or irretrievable sources permit the NRC staff to make a determination whether an inspector should be dispatched to a site and to assure that corrective actions have been taken. When the licensee, in consultation with the well owner or operator, determines that a sealed source lost in a well becomes irretrievable, the licensee is required to notify NRC regional offices immediately by telephone to request approval to implement abandonment procedures. The NRC regional office, based on the information provided by the licensee, approves the abandonment if all reasonable efforts at recovery have been expended.

3. Reduction of Burden Through Information Technology

There are no legal obstacles to reducing the burden associated with this information collection. The NRC encourages respondents to use information technology when it would be beneficial to them. The NRC has issued Guidance for Electronic Submissions to the NRC which provides direction for the electronic transmission and submittal of documents to the NRC. Electronic transmission and submittal of documents can be accomplished via the following avenues: the Electronic Information Exchange process, which is available from the NRC's “Electronic Submittals” Web page, by Optical Storage Media (e.g. CD-ROM, DVD), by facsimile or by e-mail. It is estimated that approximately 23 percent of the potential 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.

5. Effort to Reduce Small Business Burden

Approximately 32 percent of NRC’s well logging licensees are small businesses. Efforts have been made to keep the requirements for information to a minimum. However, since the health and safety consequences of improper handling or use of radioactive 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.

6. Consequences to Federal Programs or Policy Activities if the Collection is not Conducted or is Conducted Less Frequently

If the information were not collected, or were collected less frequently, NRC would not have the information needed to assure that licensees are maintaining records and those licensees will continue to operate programs in a manner that will assure adequate protection of the public health and safety. Required reports are collected and evaluated on a continuing basis as events occur. Applications for new licenses and amendments are submitted only once. As a matter of NRC policy, materials licenses will generally be approved for a 15-year license authorization limit in accordance with NRC memorandum dated August 18, 2017, “Procedure for Implementing the 15 Year Materials Licenses Term” (Agencywide Documents Access and Management System Accession No. ML17200D110). Applications for renewal of licenses are submitted every 15 years. Information submitted in previous applications may be referenced without being resubmitted.

7. Circumstances Which Justify Variation from OMB Guidelines

Contrary to the OMB Guidelines in 5 CFR 1320.5(d), 10 CFR 39.31(a) requires that a licensee label (1) the source, the source holder or the logging tool containing radioactive materials; and (2) the storage or transport container. The labels are required for the life of the device and are needed to warn people that these devices or containers contain radioactive materials and that persons should notify civil authorities or the company if they find a labeled device or container.

Section 39.35(d)(2) requires that licensees submit a report to NRC within 5 days of a failed sealed source leak test. However, reporting would be required only if the test reveals the presence of 0.005 microcurie or more of removable radioactive material. The report must be filed within 5 days to permit NRC to ensure that the licensee has taken action to remove the leaking sealed source from service and to check for radioactive contamination. It also permits NRC to determine whether inspection or other response may be required to deal with potential problems impacting the public health and safety.

Section 39.65(c) requires licensees to retain records of personnel dosimeters and bioassay results until the Commission authorizes disposition. The information documents the radiation doses received by the licensee's employees. This information may be needed to reconstruct a worker's dose history in the event the worker loses his/her records.

Section 39.73 requires licensees to maintain certain documents and records at specified locations. The retention periods for the various documents vary and may be required for as long as the license is in effect. This information is needed at the various sites so that the licensee's operating personnel can have easy access to the documents they need to safely perform well logging activities.

Section 39.75 requires licensees conducting operations at temporary job sites to maintain certain documents and records at each temporary job site. The retention periods for the various documents vary and may be required for as long as the license is in effect. This information is needed so that the licensee's operating personnel can have easy access to the documents they need safely perform well logging activities.

Section 39.77(a) requires immediate telephone notification, with a written report within 30 days, because the loss of licensed material and rupture of a sealed source could cause extensive radioactive contamination. Immediate notification would permit NRC to judge the severity of the situation and consider whether NRC should take immediate action. The confirmatory letter within 30 days is needed to permit NRC to judge whether the licensee has taken corrective actions and whether NRC should consider follow-up actions.

Section 39.77(c) requires licensees to notify NRC by telephone if a source becomes irretrievable and obtain NRC approval for abandoning a sealed source in a well. The requirement for prompt notification is needed to permit NRC to judge whether all reasonable effort at recovery has been expended.

Section 39.77(d) requires that the licensee must make a written report to NRC within 30 days after the source has been classified as irretrievable. The written report within 30 days is needed to assure that the abandonment procedures are carried out promptly and satisfactorily. Furthermore, the report constitutes a record to alert State regulatory agencies about a sealed source lodged in the well and permission is requested to reenter the well.

8. Consultations Outside the NRC

Opportunity for public comment on the information collection requirements for this clearance package was published in the Federal Register on May 27, 2020 (85 FR 31814). Nine companies that perform well logging were contacted by e-mail as part of the public consultation process to request comments on this clearance package. No responses or comments were received as a result of the FRN or the staff’s direct solicitation of comment.

9. Payment or Gift to Respondents

Not applicable.

10. Confidentiality of Information

Confidential and proprietary information is protected in accordance with NRC regulations at 10 CFR 9.17(a) and 10 CFR 2.390(b). However, no information normally considered confidential or proprietary is requested.

11. Sensitive Questions

None.

12. Estimated Burden and Burden Hour Cost

Annual Burden

	NRC Licensees (hrs/yr)	Agreement State Licensees(hrs/yr)	Total Burden
Reporting	33 (4.1 hrs/response)	55 (3.4 hrs/response)	88
Recordkeeping	4,659	33,457	38,116
Third-Party Disclosure	275	1,975	2,250
TOTALS	4,967	35,487	40,454

The total burden for Part 39 is 40,454 hours. The total cost is $11,246,212 (40,454 x $278/hr). The burden estimates are based on staff’s best estimate of the time required to perform information collection activities.

Annual Responses

	NRC	Agreement States	Total
Reporting	8	16	24
Record Keeping	22	158	180
Third-Party Disclosure	440	3,160	3,600
Total Number of Responses	470	3,334	3,804

Total number of responses 3,804

The $278 hourly rate used in the burden estimates is based on the NRC’s fee for hourly rates as noted in 10 CFR 170.20 “Average cost per professional staff-hour.”  For more information on the basis of this rate, see the Revision of Fee Schedules; Fee Recovery for Fiscal Year 2019 (84 FR 22331, May 17, 2019). 

13. Estimate of Other 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 38,116 hours, the storage cost for this clearance is $4,239 (38,116 hours x 0.0004 x $278/hour).

14. Estimated Annualized Cost to the Federal Government

It is estimated that the NRC annual cost of professional staff effort for activities other than application review is $18,348 (66 hrs x $278/hr).

15. Reason for Change in Burden or Cost

The overall burden has decreased by 4,477 hours from 44,931 hours to 40,454 hours (NRC Licensees = 4,967 hrs + AS Licensees = 35,487 hrs) because of a decrease in the number of licensees by 20 from 200 to 180. However, there was an increase in the burden based on an increase of the number of reported well logging sources that were abandoned because they were unable to be retrieved

The number of NRC licensees has decreased by 4 from 26 to 22, resulting in a burden decrease of 890 hours from 5,857 hours to 4,967 hours (33 reporting hrs + 4,659 recordkeeping hrs + 275 third-party disclosure hrs).

The number of Agreement State (AS) licensees has decreased by 44 from 174 to 158, resulting in a burden decrease of 3,587 hours from 39,074 to 35,487 hours (55 reporting hrs +33,457 recordkeeping hrs + 1,975 third-party disclosure hrs).

The number of well logging licensees licensed by the Agreement States is assumed to follow the same ratio as the total number of NRC licensees to Agreement States licensees. The current ratio of NRC to Agreement State licenses is 1:7.2.

The number of NRC licensees is expected to remain at or near the current number (22) over the coming three years. The number of Agreement State licensees is likewise expected to remain at or near the current number (158) over the coming three years.

In addition, there was an increase in professional cost from $267/hr to $278/hr.

16. Publication for Statistical Use

None.

17. Reason for Not Displaying the Expiration Date

The requirement is contained in a regulation. Amending the Code of Federal Regulations to display information that, in an annual publication, could become obsolete would be unduly burdensome and too difficult to keep current.

18. Exceptions to the Certification Statement

None.

2. Collection of Information Employing Statistical Methods

Statistical methods are not used in this collection of information.

Agreement State Licensees’ Burden and Cost

It is estimated that, for Agreement State licensees and applicants, there will be 16 responses and a reporting burden of 55 hours annually, there will be 158 recordkeepers and a recordkeeping burden of 33,457 hours annually, and there will be 158 respondents with a third-party disclosure burden of 1,975 hours annually. The Agreement State licensees’ total burden will be 35,487 hours (55 hrs reporting + 33,457 hrs recordkeeping + 1,975 hrs third-party disclosure) at a cost

$9,865,386 [35,487 hours (AS licensees’ total burden) x $278/hr].

Appendix A- Description of Information Collection Requirements for 10 CFR Part 39

1. Need for and Practical Utility of the Information Collection

Section 39.11 provides that an applicant for a specific license to use licensed material in well logging operations must submit NRC Form 313, “Application for Material License.” The NRC materials licensing staff will review the information submitted on NRC Form 313 to determine whether an applicant for a license has adequate training, experience, equipment, facilities, and procedures for the use of licensed material to protect the public health and safety.

The use of NRC Form 313 is approved by OMB under clearance number 3150-0120, which should be referred to for information collection burden and supporting data.

Section 39.13 provides that an applicant must submit the following information with the application:

39.13(b) - A description of training programs that specifies initial training, on-the-job training and annual safety reviews to be provided by the licensee;

39.13(c) - Written operating and emergency procedures covering important safety aspects of the radiation safety program;

39.13(d) - Internal inspection program;

39.13(e) - Description of overall organizational structure as it applies to radiation safety responsibilities in well logging, including specified delegations of responsibility and authority;

39.13(f) - (1) Description of procedures for leak testing sealed sources, or

(2) Manufacturer and model number of the leak test kits to be used.

This information is reviewed by the NRC staff to determine whether the training, radiation safety, and internal inspection programs and procedures and the licensee's organizational structure will provide adequate protection of the public health and safety. The NRC review and the findings of this information form the basis for NRC licensing decisions. Burden and cost has been approved under OMB clearance number 3150-0130.

Section 39.13(d) provides that a licensee must keep annual internal inspection of the job performance records for each logging supervisor for 3 years. These records are reviewed by NRC inspectors to verify that the licensee is maintaining an effective inspection program and that problems are being identified and corrected.

Sections 39.15(a) and (b) requires that a licensee wishing to conduct well logging operations with a sealed source must first have, and retain as a record, a written agreement with the well owner or operator that identifies who will: carry out responsibilities with regard to recovery of sealed sources which become lodged or lost in a well; perform radiation monitoring; decontaminate the site, equipment, and personnel, if necessary; and that within 30 days after a well logging source has been classified as irretrievable, certain requirements will be implemented to immobilize and protect the separated well logging tool and source. The licensee must retain a copy of the written agreement for 3 years after the completion of the well logging operation. A permanent identification plaque must be mounted at the surface of the well in which a well logging source has been abandoned. In addition to a warning, the plaque must contain: the date the sealed source was abandoned, the name of the well owner or operator, the well name and well identification number(s) or other designation, identification of the source by radionuclide and quantity of activity, and the depth of the source and the depth to the top of the plug.

The written agreement is needed to ensure that recovery or abandonment procedures will be implemented in the event of a lodged or irretrievable well logging source. The agreement binds the well owner or operator (non licensee) to immobilizing the source with a cement plug, protecting it from subsequent damage with a drill deflecting device, and posting the wellhead with an appropriate plaque. Without this agreement, the well logger would be unable to complete recovery or abandonment procedures if the well owner or operator refused. The identification plaque is necessary to warn anyone reentering the well about the presence of the abandoned source and to provide information on the source and its location within the well.

Section 39.15(c) provides that a licensee or applicant may apply to the Commission for approval of proposed procedures to abandon an irretrievable well logging source in a manner other than that currently authorized. Such an application would be reviewed by the NRC to determine whether the proposed procedures would provide an adequate margin of protection to the environment, public health and safety.

Section 39.17 provides that the NRC may require further statements, signed under oath or affirmation, after the filing of the application and before expiration of the license to enable the NRC to determine whether a license should be modified or revoked. Such additional information is sometimes needed to clarify information or to rectify deficiencies in existing programs for protection of the public health and safety, the common defense and security, or protection of the environment.

The additional information submitted is reviewed by the NRC staff to assess the adequacy of the applicant's physical plant, procedures and plans for protection of the public health and safety, common defense and security, and protection of the environment. The NRC review and the findings based on this information form the basis for NRC decisions concerning the issuance, amendment, or revocation of a license.

Burden and cost associated with further statement requests are included in the burden and cost data for submittal of applications on NRC Form 313, and are covered by OMB clearance number 3150‑0130, which should be referred to for further burden and cost information.

Section 39.31(a) requires that a licensee label (1) the source, the source holder, or the logging tool containing radioactive materials; and (2) the storage or transport container. The labels are needed to warn people that these devices or containers contain radioactive materials and that persons should notify civil authorities or the company if they find a labeled device or container.

Section 39.33(d) provides that a licensee must maintain calibration records for a period of 3 years for each installation and temporary job site, after the date of calibration of a survey instrument. Calibration of radiation survey instruments is necessary to ensure that these instruments function properly.

The information documents that the calibrations were performed. The records also permit NRC inspectors to verify that the licensee is keeping a calibrated and operable radiation survey instrument at each field station and temporary job site to make required radiation surveys. Inspections are conducted at least every 3 years.

Section 39.35(a) requires the licensee to keep a record of the results of leak testing of sealed sources for 3 years after the leak test is performed and record the leak test results in units of microcuries.

The information documents that the leak tests were performed periodically. The records also permit NRC inspectors to verify that the licensee is performing the leak tests.

Section 39.35(d)(2) provides for reporting of leak test failures by the licensee to the NRC within 5 days of receiving the test results. The reporting requirement is needed to inform the NRC that the licensee has taken actions to remove the leaking sealed source from service and to check for radioactive contamination.

The information contained in the report allows NRC regional offices to determine, within approximately 1 week, whether an inspector should be sent to check potential problems that may adversely affect public health and safety.

Section 39.37 provides for a licensee to keep records of each semiannual physical inventory to account for all licensed material received and possessed under the license. The record of inventory must be retained for 3 years. The information is needed to indicate that the licensee has conducted semiannual inventories to account for licensed material received and possessed under the license.

The information documents that sources possessed under the license were accounted for at the time of inventory. The information also permits NRC inspectors to verify that the licensee has conducted an inventory at least every 6 months.

Section 39.39 (a) & (b) requires that a licensee keep utilization records for sealed and unsealed sources of licensed material. The records must be retained for 3 years. This information permits the licensee to trace the history of the use of sources, radioactive markers, or unsealed licensed material if there are any questions concerning licensed material.

The information also permits NRC inspectors to verify that the licensee is utilizing licensed material appropriate to particular well logging operations.

Section 39.43(a) requires that a licensee maintain a record of defects found and repairs made as a result of visual checks of source holders, logging tools, and source handling tools. The record must be retained for 3 years. The records are reviewed by NRC inspectors to ensure that the licensee is maintaining an effective program for identification and correction of defects.

Section 39.43(b) provides that a licensee must maintain records of semiannual inspections and maintenance for 3 years. The inspection and maintenance are needed to ensure that the sealed sources and source holders are in good working condition.
