The radiological environmental monitoring stations are listed in Table B.41.

The locations of'the stations with respect to the Seabrook Station are shown on  ;

the maps in Figures B.4-1 to B.4-6. l

- Direct radiation measurements are analyzed at the 6tation. All other radiological analyses for environmental samples are performed at the Yankee Environmental Laboratory. The Laboratory participates in the U.S. Environmental Protection Agency's Environmental Radioactivity Laboratory Intercomparison Studies Program for all the species and matrices routinely analyzed.

Pursuant to Specification 4.12.2, the land use census will be conducted 'during i the growing season

• at least once per 12 months.

The growing season is defined, for the purposes of the-land use census. as the period from June i to October 1.

The method to be used.for conducting the census will consist of one or more of the followint,. as appropriates door to-door survey. visual inspection from roadside, serial survey, or consulting with local agricultural authorities. .

Technical Specification 6.8.1.3 requires that the results of the Radiological Environmental Monitoring Program be summarized in the Annual Radiological Environmental Operating Report 'in the format of the table in the Radiological Assessment Branch Technical Position, Revision 1. 1979.* - The general table format will be.used with one exception and one clarification, as follows. The  ;

mean and range values will be. based not upon detectable measurements only, as e

specified in the NRC Branch Technical Position, but upon all measurements.- This will prevent the positive bias associated with.the calculation of the mean and [

range based upon detectable measurements only. Secondly, the Lower Limit of Detection column will specify the LLD required by ODCM Table A.5-2 for that radionuclide and sample medium.
