toring program: ` Preapplication Monitoring. The program of field monitoring and data collection is used to support the applicant’s baseline hydrological descriptions. ` Construction Monitoring. The program of hydrological monitoring to control anticipated impacts from site preparation and construction and to detect any unexpected impacts arising from these activities may include preconstruction monitoring to establish a baseline for assessing the subsequent impacts of site preparation and construction. This monitoring will be needed only in unusual circumstances when specific adverse impacts are predicted. ` Preoperational Monitoring. The program of hydrological monitoring establishes a baseline for identifying and assessing environmental impacts resulting from plant operation. ` Operational Monitoring. The program of hydrological monitoring establishes the impacts of operation of the plant and detects any unexpected impacts arising from plant operation. October 1999 6.3-5 NUREG-1555 Each of these aspects is discussed in greater detail below. If available, documentation of data quality objectives should be reviewed. NUREG-1555 6.3-6 October 1999 Preapplication Monitoring Information from the applicant’s preapplication monitoring program is used to aid in the assessment of site acceptability and to support the staff’s database as needed to identify surface-water or groundwater system impacts that could result from construction and operation of the proposed plant. Generally, data are needed on a seasonal basis and should be sufficient to characterize seasonal variations throughout at least one annual cycle. The reviewer should analyze the available data to determine that they are adequate to support the environmental descriptions of ESRP 2.3 and the impact analyses of ESRPs 4.2, 5.2, 5.3.1, and 5.3.2. The following factors should be considered in the analysis: ` the location and number of monitoring stations (and wells) as required to consider the following
