The conclusions of this assessment indicate that <br /> the maximum individual cancer risk associated with facility operation <br /> would be approximately 3.1 x 10-6 (i .e. , 3.1 in one million) . This means <br /> that if a population of one million adults were exposed continuously to <br /> the maximum annual average air concentration associated with 30-year <br /> operation of the proposed facility, 3.1 of the exposed individuals would <br /> be expected to die from cancer. This is a conservative estimate because <br /> few, if any, individuals would actually be exposed to the maximum annual <br /> average concentration, 24 hours per day, over the operating lifetime of <br /> the facility. The assessment also conservatively estimates that far less <br /> 3-64 <br /> 101-30.R5 4/13/89 <br />
