'.'le rasults of the radiological envirc~* a' nenitoring propan are intended ;o suppl cent the rasult of the radiological effluent ronitoring by veri'ying that the reasurable concentrations of radicactive materials and levels of radiation a e nct hicher than expected on the basis of the effluent reasurerents and redeling of the environmental exposure pathways. Thus, the specified environmental scni.crina; progrx prevides seasure=ents of radiatica and of radicactive cate;ials in those expcsure pathways and for those rcdionuclides, vhich lead to the highese potential radiation exposure of individuals resulting frca the station operaticn. "'he initial rv'.iological environmental scnitcring preg a shculd be conducted fr the first three years of ccm=erical cperation (or other pericd cer-espending to a =r icu= bu:mup in the initial cere cycle). Folleving this pericd, pre ra= cha.ges niy be propcsed based en operatienal experience. The specified detection capacilities are state-of-the-art for routine environ = ental seasurements in industrial laboratories. The UD 's for I-131 in water, milk and other feed products cor espond to one-quarter of the Appendix I (10 CFR Part 50) design cbjective dose-equivalent of 15 mren/yr. They are based on the assumptica given in Regulatory Gaide 1.109, except the change for an infant censu=inc 3301/yr. cf drinking water instead of 5101/yr. The census of milk animals and gardens (if applicable) producing bread leaf.getstion is based on the requirement in Appenaix I of 10 CF3 Part 50 to "Identif'/ chan;es in the u:e of unrestricted areas (e.g. for agricultural pu: poses) to pe =it mcdifications in manitortng progrs=s for evaluating doses to individuals frc= principal pathuays of exposure". The consumption of milk frca anirnis grazing on <:entaminated pasture and of leafy vegetation contaminated by airbcrne ra:iicied.ine is a major pctential scue ce of exposure. Samples frca milk animals are considered a better indicator of radioiciine in the environnent than vegetation. ~f the census reveals milk ani=als are not present or are unavailable for sa pling, then vegetation cust be sampled. Tne 5CC sq. ft. garden, censidering 20% used for

g broad leef vegetation (i.e. similar tc lettuce and cabbage), and a vegetatun: yield of 2 kg/r2, vill produce the 26 kg/yr asst. red in Regulatory Caide 1.109 for child censu=ptica of leafy vego.iticn.

The option to consider the garden to be broad leafy vegetaticn at the site beundary in a sector with the highest X/Q should be censervative and that locatica na;, be used to calculate deees due to radicective effluent releases in place of the actual locations which veuld be determined by the census. This eptien does not apply to plants with elevated rc' ases as defined in Regtlatcry Gutie 1.11.. '~he pernis:ica of deviation frcs the sarc.ing schedule ic based en the reccgnition of unavoidable practical difficulties which in the absent e of the per.itted deviaticrc woul1 result in violation cf the specifications. The r ec.u '.z amen t for the pp.rticipation in the OA crcss-chech progrn, or sirilar crc.:cm, is based on the need for indapendent ch2cks on the erecicicn and ace.uacy of radicactive material in environ w.ntal srcle matri:es as p1rt of the mea:urenent of the quality assarance pregra. for envircamental acr.itori:.; in order to de:cnstrr.t2 that 'hc esults are rea:crably valid. 3.2-2 O 1[h j J e
