equences of routine releases. The applicant should describe the methods for generating these χ/Q and D/Q values. The applicant should provide a detailed description of the model inputs, including the suitability of input parameters, source configuration, and topography. The meteorological data used as input to the models should be provided. 2.7.4 Meteorological Monitoring The applicant should describe the preoperational and operational programs for meteorological measurements at the site, including all data-collection programs used to describe the site meteorological and atmospheric dispersion characteristics. The description should include the following: • A site map showing tower locations with respect to man-made structures, topographic features, and other site features that may influence site meteorological measurements. • Distances to nearby obstructions of the flow in each downwind sector. • Discussion of measurements made; instruments and performance specifications; measurement elevations and instrument siting; calibration and maintenance procedures; data output and recording systems and locations; and data processing, archiving, and analysis procedures. • Estimates of overall system accuracy for each meteorological parameter measured. Regulatory Guide 1.23 provides guidance for an onsite meteorological measurements program that the NRC staff considers acceptable for the collection of basic meteorological data needed to support plant licensing and operation. 2.8 Nonradiological Health The applicant should describe the environment at the site and within the vicinity of the site with respect to existing nonradiological human-health. This includes the identification of people or groups that could be vulnerable to nonradiological health impacts including public health, etiological agents, transportation activities, noise and electromagnetic fields. This section provides the basis for evaluation of impacts on human health from building and operating the
