DOCUMENT ACTION: Withdrawal of Regulatory Guides 4.5, ``Measurements of Radionuclides in the EnvironmentSampling and Analysis of Plutonium in Soil'' and 4.6, ``Measurements of Radionuclides in the Environment Strontium89 and Strontium90 Analysis.''
SUBJECT CATEGORY:
Withdrawal of Regulatory Guides 4.5 and 4.6
SUMMARY:
Withdrawal of Regulatory Guides (4.5 and 4.6)
SUPPLEMENTAL INFORMATION
I. Introduction
The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Regulatory Guide (RG) 4.5, ``Measurements of Radionuclides in the EnvironmentSampling and Analysis of Plutonium in Soil,'' and RG 4.6, ``Measurements of Radionuclides in the EnvironmentStrontium89 and Strontium90 Analysis.'' Both of these guides were published in May 1974.
These regulatory guides provide prescriptive guidance to licensees
and applicants on the sampling and laboratory analysis of Strontium and
Plutonium. The guides provided guidance on compliance with a provision
in 10 CFR Part 20, ``Standards for Protection against Radiation.'' That
provision, 10 CFR 20.106, ``Concentrations in Effluents to Unrestricted
Areas,'' was deleted, and that subject matter is addressed in a new section, 10 CFR 20.1302.
``Compliance with dose limits for individual members of the
public.'' Paragraphs (a) and (b) of 20.1302 contain the effluent
standards and allowable radionuclide concentrations in effluent releases.
Updated performance based guidance for the measurement of plutonium (Pu), strontium89 (Sr\89\), and strontium90 (Sr\90\) is now provided through Regulatory Guide 4.15, ``Quality Assurance for Radiological Monitoring Programs (Inception through Normal Operations to License Termination)Effluent Streams and the Environment,'' published July 2007. This guidance references NUREG1576, ``MultiAgency Radiological Laboratory Analytical Protocols Manual (MARLAP),'' published in July 2004. MARLAP provides analytical detail for measurement of Pu, Sr\89\, and Sr\90\ which includes methods described in RG 4.5 and 4.6 and more recent methods and procedures that are also acceptable to the staff. NUREG1576 is available electronically through the NRC's Agencywide Documents Access and Management System at http://www.nrc.gov/reading rm/adams.html, under Accession No. ML060930645.
II. Further Information
The withdrawal of RGs 4.5 and 4.6 does not alter any prior or existing licensing commitments or conditions based on their use. The guidance provided in these regulatory guides is neither necessary nor current. Regulatory guides may be withdrawn when their guidance is superseded by congressional action or no longer provides useful information.
Regulatory guides are available for inspection or downloading through the NRC's public Web site under ``Regulatory Guides'' in the NRC's Electronic Reading Room at: http://www.nrc.gov/readingrm/ doc collections.
In addition, regulatory guides are also available for inspection at the NRC's Public Document Room (PDR), Room O1 F21, One White Flint North, 11555 Rockville Pike, Rockville, MD 208522738. The PDR's mailing address is US NRC PDR, Washington, DC 205550001. You can reach the PDR staff by telephone at 3014154737 or 8003974209, by fax at 3014153548, and by email to pdr.resource@nrc.gov.
