REVIEW PROCEDURES The reviewer should verify that sufficient information has been provided to adequately assess the onsite meteorological measurements program and other data-collection programs used by the applicant to (1) describe local and regional atmospheric transport and diffusion characteristics, (2) ensure environmental protection, and (3) provide an adequate meteorological database for evaluation of the effects of plant operation. The reviewer should consider the following separate but related aspects of the applicant’s meteorological monitoring program: ` Preapplication Monitoring. The program of field monitoring and data collection is used to support the applicant’s meteorological descriptions. ` Site Preparation and Construction Monitoring. This is the proposed program of meteorological monitoring to control anticipated impacts from site preparation and construction and to detect any unexpected impacts arising from these activities. This program may include preconstruction monitoring to establish a baseline for assessing the subsequent impacts of site preparation and October 1999 6.4-5 NUREG-1555 construction. This monitoring will be needed only in unusual circumstances when specific adverse impacts are predicted. ` Preoperational Monitoring. The program of meteorological monitoring establishes a baseline for identifying and assessing environmental impacts resulting from plant operation. ` Operational Monitoring. The program of meteorological monitoring establishes a baseline for use in evaluation of the environmental impacts of plant operation. In terms of onsite meteorological instrumentation, the reviewer should ensure that the basic meteorological parameters measured by instrumentation at all sites include wind direction and wind speed at two levels, ambient air temperature difference between two levels, temperature, and atmospheric moisture at height(s) representative of water-vapor release (at sites at which large
