AGENCY: Nuclear Regulatory Commission.

of uranium conversion facilities where the possibility of exposure to 
yellowcake dust exists, including exposure conditions with and without 
the use of respiratory protection devices.

DATES: Submit comments by May 11, 2012. Comments received after this 
date will be considered if it is practical to do so, but the NRC is

II. Further Information

    The NRC is issuing for public comment a draft guide in the agency's 
``Regulatory Guide'' series. This series was 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 
NRC'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 draft regulatory guide, entitled, ``Bioassay at Uranium 
Mills,'' is temporarily identified by its task number, DG-8051, which 
should be mentioned in all related correspondence. DG-8051 is proposed 
Revision 2 of Regulatory Guide 8.22, previously revised in August 1988.
    This guide is being updated to incorporate changes made in 10 CFR 
Part 20 since Regulatory Guide 8.22, Revision 1 was issued. Comments 
related to the operation of in-situ recovery mills and associated 
considerations for bioassay are of particular interest.

    Dated at Rockville, Maryland, this 6th day of March, 2012.
    For the Nuclear Regulatory Commission.
