                   TITLE 40--PROTECTION OF ENVIRONMENT
 
         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)

FOR YUCCA MOUNTAIN, NEVADA--Table of Contents
 
    Subpart B--Public Health and Environmental Standards for Disposal
 
Sec. 197.25  What standard must DOE meet?

    The DOE must determine the earliest time after disposal that the 
waste package would degrade sufficiently that a human intrusion (see 
Sec. 197.26) could occur without recognition by the drillers. The DOE 
must:
    (a) If complete waste package penetration is projected to occur at 
or before 10,000 years after disposal:

[[Page 64]]

    (1) Demonstrate that there is a reasonable expectation that the 
reasonably maximally exposed individual receives no more than an annual 
committed effective dose equivalent of 150 microsieverts (15 millirems) 
as a result of a human intrusion, at or before 10,000 years after 
disposal. The analysis must include all potential environmental pathways 
of radionuclide transport and exposure; and
    (2) If exposures to the reasonably maximally exposed individual 
occur more than 10,000 years after disposal, include the results of the 
analysis and its bases in the environmental impact statement for Yucca 
Mountain as an indicator of long-term disposal system performance; and
    (b) Include the results of the analysis and its bases in the 
environmental impact statement for Yucca Mountain as an indicator of 
long-term disposal system performance, if the intrusion is not projected 
to occur before 10,000 years after disposal.
