Public Health Impacts

The certificate holder shall operate the uranium mill to ensure that, during operation of the uranium mill, public health impacts do not exceed the following limits:


Annual dose equivalent not exceeding 25 millirems to the whole body, 75 millirems to the thyroid and 25 millirems to any other organ of any member of the public as the result of exposures to planned discharges of radioactive materials except radon and its daughters.


Concentrations of total suspended particulates resulting from facility operation at any location that is routinely inhabited or visited by members of the public not exceeding 19 ug/m3 annual geometric means. The 24-hour concentration at these locations must not exceed 37 ug/m3 more frequently than once per year. In any case where measurable impacts might occur in wilderness areas designated by federal or state agencies or in designated national or state parks, the site certificate holder shall determine the concentration of total suspended particulates at the wilderness or park boundary nearest the facility. The concentration limit at that location must not exceed 5 ug/m3 annual geometric mean nor 10 ug/m3 on a 24-hour average more frequently than once per year.
