UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF NUCLEAR MATERIAL SAFETY AND SAFEGUARDS WASHINGTON, D.C. 20555 January 5, 1993 Information Notice No. 93-03: RECENT REVISIONS TO 10 CFR PART 20 AND CHANGE OF IMPLEMENTATION DATE TO JANUARY 1, 1994 Addressees All byproduct, source, and special nuclear material licensees Purpose NRC is issuing this information notice to notify addressees of the change in the deadline for implementation of revised 10 CFR Part 20, and of recent regulatory guides and draft guides published in conjunction with the revision. This information notice also describes two recent changes to the revised Part 20. It is expected that licensees will review this information for applicability to their operations, distribute it to appropriate staff, and consider actions to prepare for, and incorporate, these changes. However, suggestions contained in this information notice are not new NRC requirements; therefore, no specific action nor written response is required. Description of Circumstances In December 1990, the Commission approved the final revised Part 20, "Standards for Protection Against Radiation," which became effective June 21, 1991. At the time of the publication in the Federal Register, licensees were permitted to delay implementation of the new revisions until January 1, 1993. In the fall of 1991, the Nuclear Management and Resources Council (NUMARC) requested that the Commission extend the deadline for implementation of the revised Part 20 for one year, to January 1, 1994. This delay would allow all licensees sufficient time to prepare for and implement for the rule. In May 1992, the Commission published a proposed rule in the Federal Register, to extend the implementation date of the revised Part 20 to January 1, 1994. Thirty-six comment letters were received on the proposed rule, with the majority in favor of the extension. On August 26, 1992, the Commission published, in the Federal Register (Attachment 1), a final rule that extends the implementation deadline date, for the revised Part 20, to January 1, 1994. On August 31, 1992, additional changes in the revised Part 20 were published in the Federal Register (Attachment 2) in response to a Presidential memorandum requesting agency review and modification of Federal government 9212290163 . IN 93-03 January 5, 1993 Page 2 of 3 regulations that cause any unnecessary burden. The areas in Part 20 affected included: 1. Exemptions to Posting Requirements (10 CFR 20.1903(b)) - to include exceptions to posting requirements for rooms occupied by patients otherwise releasable pursuant to 10 CFR Part 35.75; 2. Procedures for Receiving and Opening Packages (10 CFR 20.1906(b)) - to eliminate certain provisions for contamination monitoring of packages containing certain types of radioactive material. Discussion The Federal Register notices that describe each of these final rules are in Attachments 1 and 2. The notices give statements of consideration for the change in the implementation deadline, and for changes to the revised Part 20. Licensees are encouraged to review the applicable regulatory guides for assistance in the implementation of Part 20. The regulatory guides that have been developed to assist with the implementation of the revised Part 20 include the following: 1. Regulatory Guide 8.7, Revision 1, "Instructions for Recording and Reporting Occupational Exposure Data" 2. Regulatory Guide 8.25, Revision 1, "Air Sampling in the Workplace" 3. Regulatory Guide 8.34, "Monitoring Criteria and Methods to Calculate Occupational Radiation Doses" 4. Regulatory Guide 8.35, "Planned Special Exposures" 5. Regulatory Guide 8.36, "Radiation Dose to the Embryo/Fetus" Copies of issued regulatory guides may be purchased from the Government Printing Office (GPO) at the current GPO price. Information on prices may be obtained by contacting the Superintendent of Documents, U.S. Government Printing Office, P.O. Box 37082, Washington, D.C. 20013-7082, or by telephoning (202) 275-2060 or (202) 275-2171. Several additional guides have been published in draft form for comment and should be published as regulatory guides by mid-93. These are: 1. DG-8005, "Assessing External Radiation Dose from Airborne Radioactive Materials" 2. DG-8009, "Interpretation of Bioassay Measurements (Proposed Revision to Regulatory Guide 8.9)" 3. DG-8013, "ALARA Levels for Effluents from Materials Facilities" .
