mit of detection for each analysis; and (7) the approxi- mate starting date and duration of the program. The discussion should include the justification for the choice of sampling sites, analyses, and sampling frequencies. Reference may be made to Sections 5.1.2 and 5.1.3 regarding meteorological and hydrological baseline studies. Summarize any information available from the literature regarding back- ground radiological characteristics of the site that were considered in design- ing the program. 5.2 Operational Monitoring Describe the proposed operational monitoring program for planned operations. Review of this description will be facilitated if maps of proposed observation sites and tabular presentations of summary descriptors of such factors as sample collection and analysis frequency, type of sampling, method of collection, analytic method, preanalysis treatment, instrumentation, and minimum sensitiv- ities are included. The discussion should include the justification for the choice of sampling sites, analyses, and sampling frequencies. The program description should be explicit with respect to the parameter limits that are not to be exceeded under normal operating conditions and with respect to the actions planned in the event the limits are exceeded. 5.2.1 Meteorological Monitoring System Describe the proposed operational meteorological monitoring system. In addition to the physical description, discuss how the data collected during 26 the preoperational monitoring were used to design the operational monitoring system. Also discuss details of proposed maintenance and inspection of the moni- toring system. 5.2.2 Hydrological Monitoring System Describe the proposed operational hydrologic monitoring system. In addi- tion, discuss how the baseline hydrologic data were considered in the design of the operational monitoring system. Particular detail should be provided in the discussion for the piezometric surface and its expected variations, soil moisture
