[Federal Register: March 30, 2007 (Volume 72, Number 61)] [Notices] [Page 15173-15175] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr30mr07-123] ----------------------------------------------------------------------- NUCLEAR REGULATORY COMMISSION Interim Regulatory Guide: Issuance, Availability The U.S. Nuclear Regulatory Commission (NRC) has issued an interim revision to an existing guide in the agency's Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. The revised guide, entitled ``Quality Assurance for Radiological Monitoring Programs (Inception Through Normal Operations to License Termination)--Effluent Streams and the Environment,'' is identified as Interim Revision 2 of Regulatory Guide 4.15. Like its predecessor, this interim revision describes a method that the NRC staff considers acceptable for use in designing and implementing programs to ensure the quality of the results of measurements of radioactive materials in the effluents from, and environment outside of, facilities that process, use, or store radioactive materials during all phases of the facility's life cycle. Quality assurance (QA) is a fundamental expectation of Title 10, ``Energy,'' of the Code of Federal Regulations (10 CFR) for items and activities that are relied on to protect the health and safety of the public and the environment. This interim guide serves as a final regulatory guide for, and may be used by applicants and licensees of nuclear power reactors. It also presents draft NRC staff positions on a method for designing and implementing QA programs for use by non-nuclear power reactor applicants and licensees subject to the agency's QA requirements. The NRC staff seeks public comments on this regulatory guide with respect to its application to such licensees. The NRC staff will issue this guide in final form after resolving any comments received during the public comment period. Interim Revision 2 of Regulatory Guide 4.15 specifically applies to facilities for which NRC regulations require routine monitoring of radioactive effluents to the environment, and particularly those facilities licensed under the following regulations:10 CFR Part 50, ``Domestic Licensing of Production and Utilization Facilities'' 10 CFR Part 52, ``Licenses, Certifications, and Approvals for Nuclear Power Plants'' 10 CFR Part 61, ``Licensing Requirements for Land Disposal of Radioactive Waste'' 10 CFR Part 72, ``Licensing Requirements for the Independent Storage of Spent Nuclear Fuel, High-Level Radioactive Waste, and Reactor-Related Greater Than Class C Waste'' 10 CFR Part 76, ``Certification of Gaseous Diffusion Plants'' The guidance may also apply to other NRC-licensed facilities, for which the agency may impose specific license conditions for effluent or environmental monitoring, as deemed necessary to ensure the health and safety of the public and the environment, including those licensed under the following regulations: 10 CFR Part 30, ``Rules of General Applicability to Domestic Licensing of Byproduct Material'' 10 CFR Part 40, ``Domestic Licensing of Source Material'' 10 CFR Part 70, ``Domestic Licensing of Special Nuclear Material'' [[Page 15174]] Finally, radiological standards for occupational workers and members of the public are codified in 10 CFR Part 20, ``Standards for Protection Against Radiation.'' As used in the context of Interim Revision 2 of Regulatory Guide 4.15, QA comprises all those planned and systematic actions that are necessary to provide adequate confidence in the assessment of monitoring results. Quality control (QC) comprises those QA actions that provide a means to measure and control the characteristics of measurement equipment and processes to meet established standards; QA includes QC. Interim Revision 2 of Regulatory Guide 4.15 makes no further effort to distinguish those elements that may be considered QC from those composing QA. Quality assurance is necessary to ensure that all radiological and nonradiological measurements that support the radiological monitoring program are reasonably valid and of a defined quality. These programs are needed (1) to identify deficiencies in the sampling and measurement processes and report them to those responsible for these operations so that corrective action can be taken, and (2) to obtain some measure of confidence in the results of the monitoring programs to assure the regulatory agencies and the public that the results are valid. All steps of the monitoring process (for example, sampling, shipment of samples, receipt of samples in the laboratory, preparation of samples, radiological measurements, data reduction, data evaluation, and reporting of the measurement and monitoring results) should involve QA. Interim Revision 2 of Regulatory Guide 4.15 presents more complete and extensive guidance on QA for facilities where radiological effluent or environmental monitoring is required by NRC regulations.\1\ However, this guidance does not address all topics and elements that a facility's QA program may require (such as requirements of Appendix B to 10 CFR Part 50 for nuclear power plants or 10 CFR 76.93 for gaseous diffusion uranium enrichment facilities). --------------------------------------------------------------------------- \1\ While not specific to QA, the following regulatory guides also address measurements of radioactive materials in effluents and the environment: Regulatory Guide 1.21, ``Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants.'' Regulatory Guide 4.1, ``Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants.'' Regulatory Guide 4.14, ``Radiological Effluent and Environmental Monitoring at Uranium Mills.'' Regulatory Guide 4.16, ``Monitoring and Reporting Radioactivity in Releases of Radioactive Materials in Liquid and Gaseous Effluents from Nuclear Fuel Processing and Fabrication Plants and Uranium Hexafluoride Production Plants.'' --------------------------------------------------------------------------- In addition, although Interim Revision 2 of Regulatory Guide 4.15 offers significant improvements in programmatic and technical guidance for QA and QC for radioactive effluent and environmental monitoring, it does not impose any new or additional requirements. Rather, this interim revision incorporates updated scientific and regulatory concepts concerning radioanalytical QA, which the NRC and industry have previously published not as requirements, but as good practices. Licensees may continue to use Revision 1 of Regulatory Guide 4.15, dated February 1979, if they so choose. Consequently, no backfit, as defined in 10 CFR 50.109, ``Backfitting,'' is either intended or implied. The NRC previously solicited public comment on Revision 2 of Regulatory Guide 4.15 by issuing Draft Regulatory Guide DG-4010 in November 2006. The public comment period closed on December 17, 2006, and the staff has appropriately addressed all comments received. The staff's responses to all stakeholder comments received are available in the NRC's Agencywide Documents Access and Management System (ADAMS) at http://www.nrc.gov/reading-rm/adams.html, under Accession ML070380010. However, at the time of issuance, the NRC erroneously described Draft Regulatory Guide DG-4010 as applicable only to nuclear power reactor applicants and licensees. The NRC staff intended that this regulatory guide apply to all applicants and licensees subject to the agency's QA requirements. Accordingly, the NRC is now issuing Revision 2 of Regulatory Guide 4.15 as an interim regulatory guide, which is applicable only to nuclear power reactor applicants and licensees. The NRC staff is also soliciting comments on this interim guide with respect to its application to non-nuclear power reactor applicants and licensees subject to the agency's QA requirements. The NRC staff will issue this guide in final form after resolving any comments received during the public comment period. Comments on this interim revision may be accompanied by relevant information or supporting data. Please mention Interim Revision 2 of Regulatory Guide 4.15 in the subject line of your comments.
