Attention: Division of Liconemg and Regulatica Gentiamens The Rhode Is1cnd Atcmic Energy Consission (RIAEC) herab7 submits for approval of the U. S. Atcaic Energy Ccmnocion (USA 20) infornticn to establish an 3

ataoophoric dilution factor of 10 se:/n for determining the permissible average concentration of radiotetivu offluent from the reacter effluent diuposal stack which is 22 inches in diaator and 11$ foot hi; hor than the surrounding t

terrain. Such a dilution factor &pplicd to the disposal of cirborne radioutin c:sterLd is eufficient to enaure tJ st the yccr3y eversge concentration of such i
