Content:
haracteristics of the power-transmission system and maintenance procedures necessary for determining environmental impacts to the aquatic ecosystems and provide any additional information pertinent to ecological monitoring programs. ` ESRP 5.6.3. Provide information about the basic electrical design parameters, the basic structural parameters, and the maximum electric field gradient(s) and edge of right-of-way field gradients in kV/m. ` ESRP 9.2.1. Provide information on the power transmission system that is relevant to the evaluation of alternatives to the proposed action that do not require new generating capacity. ` ESRP 9.4.3. Provide background information on the proposed transmission system siting and design for the evaluation of power transmission system alternatives. Data and Information Needs 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 impacts. The following data or information should be obtained: ` basic electrical design parameters, including transmission design voltage or voltages, line capacity, conductor type and configuration, spacing between phases, minimum conductor clearances to ground, maximum predicted electric-field strength(s) at 1 m above ground, the predicted electric- field strength(s) at the edge of the right-of-way in kilovolts per meter (kV/m), and the design bases for these values (from the environmental report [ER]) October 1999 3.7-3 NUREG-1555 ` predicted noise levels resulting from transmission-system operation (from the ER) ` basic structural design parameters, including illustrations and descriptions of towers, conductors, and other structures, with dimensions, materials, color, and finish (from the ER) ` topographic maps (15-minute scale as a rule) or aerial photographs showing the proposed corridor or corridors and all existing major high voltage corridors in the region.
