c 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 variations, and the location of hydrostratigraphic units. Also discuss how any routine liquid effluent releases (e.g., water that collects in operational trenches from precipitation) will be monitored. Details of proposed inspection and maintenance of the monitoring system should also be discussed. 5.2.3 Ecological Monitoring System Describe the proposed operational ecological monitoring system. In addi- tion, discuss how the baseline ecological data collected during the preopera- tional monitoring were used to design the system. Reference may be made to Section 5.1.3 regarding the selection of indicator organisms and statistical methods of analyses. 5.2.4 Radiological Monitoring System Describe the proposed operational radiological monitoring system. In addi- tion, discuss how the baseline radiological data collected during preoperational monitoring were used to design the system. As with the preoperational monitoring program, specific information should be provided on (1) the types of samples collected; (2) sampling locations clearly shown on a map keyed to a table listing sampling locations as a function of direction and distance from the proposed site; (3) analyses to be performed on each sample; (4) general types of sample 27 collection equipment; (5) sample collection and analyses frequency; and (6) lower limit of detection for each analysis. The discussion should include the action 4 levels for radionuclide concentrations in air and water samples and the actions to be associated with these levels. Reference may be made to Sections 5.2.1 and 5.2.2 regarding meteorological and hydrologic operational monitoring. 5.3 Postoperational Monitoring Describe the postoperational monitoring system (meteorological, hydrological, and ecological) as conceptually planned using
