ations in air, water, and vegetation between the preoperational monitoring and the operational monitoring results. In addition, any special reporting requirements or special monitoring programs (e.g., groundwater-monitoring programs), whether industry- or NRC-initiated programs, and any event reports for groundwater contamination should be noted in the ER. The type of data and information needed will be affected by site- and station-specific factors, and the degree of detail should be modified according to the anticipated magnitude of the potential radiological impacts of the radioactive effluents from the plant. The specific criteria for a radiological monitoring program can be found in RG 4.1. To the extent the information is available, the ER should include the following information: • A discussion of the environmental exposure pathways (i.e., air, water, and direct) as they relate to the type of reactor and local geography and terrain. • A map or aerial photograph of the site vicinity with proposed monitoring and sampling locations clearly identified and keyed to indicate the medium sampled at each location. The map or photograph should be suitable to show distance and direction of each location from the plant, particularly with regard to the effluent release points. • A description of the existing monitoring program when appropriate, including (1) the number and location of sample collection points and measuring devices and the pathway sampled or measured; (2) sample size, sample collection frequency, and sampling duration; (3) type and frequency of analysis; (4) general types of sample collection and measuring equipment; (5) lower limit of detection for each analysis; (6) the approximate date on which the proposed program will be effective; and (7) the quality-assurance program for REMPs (see RG 4.15, “Quality Assurance for Radiological Monitoring Programs (Inception through Normal Operations to License Termination)—Effluent Streams and the
