-----------------------------------------------------------------------

FOR FURTHER INFORMATION CONTACT: Gregory C. Chapman, U.S. Nuclear 
Regulatory Commission, Washington, DC 20555-0001, telephone: (301) 492-

SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (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 (DG), titled, ``Constraint on Releases 
of Airborne Radioactive Materials to the Environment for Licensees 
Other than Power Reactors'' is temporarily identified by its task 
number, DG-4018, which should be mentioned in all related 
correspondence. DG-4018 is proposed Revision 2 of Regulatory Guide 4.2, 
dated December 1996.
    This regulatory guide provides guidance on methods acceptable to 
the U.S. Nuclear Regulatory Commission (NRC) staff for meeting the 
constraint on air emissions of radioactive material to the environment 
as described in title 10, section 20.1101(d), of the Code of Federal 
Regulations (10 CFR 20.1101(d)). In 1996, the NRC added a constraint to 
10 CFR part 20, ``Standards for Protection against Radiation'' (Ref. 
1), to remove dual regulation by the NRC and the U.S. Environmental 
Protection Agency (EPA) and to provide an ``ample margin of safety'' to 
members of the public from air emissions of radioactive material to the 
environment.

II. Further Information

    The NRC staff is soliciting comments on DG-4018. Comments may be 
accompanied by relevant information or supporting data and should 
mention DG-4018 in the subject line. Comments submitted in writing or 
in electronic form will be made available to the public in their 
entirety through the NRC's Agencywide Documents Access and Management 
System (ADAMS).

Please include Docket ID NRC-2010-0158 in the subject line of your

identifying or contact information, the NRC cautions you against 
including any information in your submission that you do not want to be 
publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their comments to remove any 
identifying or contact information, and therefore, they should not 
include any information in their comments that they do not want 
publicly disclosed.
