Appendix II to Part 960 - NRC and EPA Requirements for Preclosure
Repository Performance
Under proposed 40 CFR part 191, subpart A - Environmental
Standards for Management and Storage, Section 191.03,
“Standards for Normal Operations”, specifies: (1) That operations
should be conducted so as to reduce exposure to members of the
public to the extent reasonably achievable, taking into account
technical, social, and economic considerations; and (2) that,
except for variances permitted for unusual operations under Section
191.04 as an upper limit, normal operations shall be conducted in
such a manner as to provide reasonable assurance that the combined
annual dose equivalent to any member of the public due to: (i)
operations covered by 40 CFR part 190, (ii) planned discharges of
radioactive material to the general environment from operations
covered by this subpart, and (iii) direct radiation from these
operations; shall not exceed 25 millirems to the whole body, 75
millirems to the thyroid, or 25 millirems to any other organ.
The guidelines will be revised as necessary after the adoption
of final regulations by the EPA.
The implementation of 40 CFR part 191, subpart A and 10 CFR part
20 is required by 10 CFR 60.111. 10 CFR 60.111 also specifies
requirements for waste retrieval, if necessary, including
considerations of design, backfilling, and schedule. 10 CFR part 20
establishes (a) exposure limits for operating personnel and (b)
permissible concentrations of radionuclides in uncontrolled areas
for air and water. The latter are generally less restrictive than
40 CFR 191, subpart A, but may be limiting under certain conditions
(i.e., if used as a maximum for short durations rather than annual
averages).
The guidelines will be revised as necessary to ensure
consistency with 10 CFR part 60.
