ld be modified according to the anticipated magnitude of the potential impacts. The following data or information should be obtained: ` a description of the onsite meteorological measurements programs (from the environmental report [ER]) ` a description of all other data collection programs used to provide data for the description of atmospheric transport and diffusion characteristics within 80 km of the plant (from the ER) ` the following information for onsite programs and, as available, for offsite sources of meteorological data: - a map showing detailed topographic features of the site (as modified by the station), including major structures and the meteorological tower(s) used to describe the meteorological characteristics of the site and immediate vicinity (from ESRP 2.7) - a map showing the general topographic features and locations of offsite meteorological facilities, providing information characteristic of the region (from ESRP 2.7) - the type of meteorological measurements, including elevations of measurements above grade (from the ER) - a description of the instruments used, including performance specifications and starting thresholds of wind instrumentation (from the ER) - calibration and maintenance procedures, including frequency of performance of calibration and maintenance, and for the preapplication program, results of calibrations, major causes of instrument outage or drift from calibration, and corrective action taken (from the ER) - a description of data output and recording systems and locations of these systems with respect to the onsite program (from the ER) October 1999 6.4-3 NUREG-1555 - data analysis procedures (from the ER), including computer programs used to screen hourly meteorological data for potential errors - estimates of overall system accuracy for each meteorological parameter measured (from the ER). II. ACCEPTANCE CRITERIA Acceptance criteria for the onsite meteorological measurements program are based on the relevant
