discussion of radiological environmental monitoring from the Branch Technical Position document is reproduced in Table 6.2-1. (2) Consider the following factors in the analysis: ` If a preoperational program is under consideration, it should be based on the development of baseline data for important pathways and the anticipated types and quantities of radionuclides to be released from the plant. - The purposes of the premonitoring program are to measure background levels and their variations along the anticipated critical pathways in the area surrounding the station; to train personnel; and to evaluate procedures, equipment, and technique. NUREG-1555 6.2-4 October 1999 - The preoperational monitoring program should be initiated 2 years before plant operation. (See Table 6.2-1 to this ESRP for recommended program durations.) Table 6.2-1. Duration of Preoperational Program for Specific Media 6 Months 1 Year 2 Years ` Airborne iodine ` Iodine in milk (while animals are in pasture) ` Airborne particulates ` Milk (remaining analyses) ` Surface water ` Groundwater ` Drinking water ` Direct radiation ` Fish and invertebrates ` Food products ` Sediment from shoreline The elements (sampling media and type of analysis) of both preoperational and operational programs should be essentially the same. ` If an operational program is under consideration, it should be based on baseline data already developed for important pathways and types and quantities of radionuclides released from the plants. - The program should be developed from baseline data that have already been obtained. - Consider adjustments being proposed by the applicant, based on operating experience. - The program should provide baseline data to evaluate the possibility of buildup of long- lived radionuclides in the environment and to identify potential physical and biological sites of radionuclide accumulation. - The program should establish the baseline from which correlations between levels of radiation and
