Je
in the populations surrounding these two DOE facilities from °
exposure to radionuclide emissions is calculated to be ents
approximately 4 tenthousandths of one percent of the risk of
eancer mortality from other causes.
Based on these extremely low risk figures, it is clear that
radionuclide emissions from DOE facilities do not cause
significant public health risks and, therefore, should not
be regulated by EPA under section 112 of the Clean Air Act.
Moreover, the already low risks from radionuclide emissions
from DOE facilities would not be appreciably reduced by the
EPA proposed regulations.
Under the proposed EPA standard,
pM
EPA has estimated that the maximum lifetime individual risk
from radionuclide emissions from DOE facilities would be
‘
reduced from 2 in 10,000 to 2 in 50,000 or 0.4 in 10,000.

Although the annual population
impact under the proposed EPA standard for DOE facilities has not
been calculated by EPA, it can roughly be estimated that the
E
eurrent annual population impact of .07 would be reduced by
~
approximately Be percent go that the resulting annual
population impact after imposition of the proposed EPA
standard would be approximately 635.
Thus, imposition of
the proposed EPA standards for DOE facilities might

This reduction in the tneidence of cancer
is precisely the same as that which would have been achieved
