by EPA for benzene fugitive sources and coke by-product
recovery plants are estimated to be 4.5 in 10,000 and 3.5 in
10,000, respectively. Id.
The maximum individual lifetime
risks from these sources after regulation are estimated
to be higher than even EPA's estimate of maximum lifetime
risks from emissions of radionuclides from DOE facilities. 4/
Further, the maximum lifetime individual risk from current
radionuclide emissions from DOE facilities is well below the
maximum lifetime individual risks estimated for the three
sources of inorganic arsenic that EPA has proposed to regulate
under section 112.
48 FR 33112 (July 20, 1983).
For these .
three sources of inorganic arsenic, the maximum individual
lifetime risks are estimated to range between 63 and 690 in
10,000 for low-arsenic copper smelters, between 230 and
3,500 in 10,000 for high-arsenic copper smelters, and
between 6.4 and 100 in 10,000 for glass manufacturing plants. Id.
Even after imposition of the proposed EPA regulations for these
sources of inorganie arsenic emissions, the maximum lifetime
individual risks from two of these source categories (i.e.,
between 9.4 and 150 in 10,090 for low-arsenic copper smelters

The risks from these benzene sources after regulation
would be 15 to 20 times higher than the ORNL risk estimates
for unregulated DOE facilities.
