• Assess the data collected to determine the magnitude of potential impacts of N. fowleri on public health during the license renewal term. • Describe proposed mitigation measures to minimize the exposure to members of the public and the rationale for not implementing any measures that were considered but rejected. DG-4015, Page 43 Electric Shock Hazards Table B-1 states the following: Electrical shock potential is of small significance for transmission lines that are operated in adherence with the National Electrical Safety Code (NESC). Without a review of each nuclear plant transmission line conformance with NESC criteria, it is not possible to determine the significance of the electrical shock potential. Specifically, 10 CFR 51.53(c)(3)(ii)(H) requires the following: If the applicant’s transmission lines that were constructed for the specific purpose of connecting the plant to the transmission system do not meet the recommendations of the National Electrical Safety Code for preventing electric shock from induced currents, an assessment of the impact of the proposed action on the potential shock hazard from the transmission lines must be provided. Section 4.8.1.1 of the GEIS discusses this issue, which concerns transmission lines built to connect the power plant with the existing transmission system. This issue is reviewed as part of the construction permit. Most transmission lines were designed to be in compliance with the NESC recommendations for electric shock hazard.14 However, unless the utility has had an active program of transmission line management aimed at reviewing changes in land use in the ROW and the operating characteristics of the transmission line, as well as ensuring compliance with changes in the NESC, the line may not meet current NESC recommendations. Information and Analysis Content If the transmission lines that were built to connect the plant to the transmission system meet current NESC clearance standards, the ER should demonstrate
