rameters (e.g., diffusion coefficients) - model verification (if any) - the applicant’s predicted temperature distributions, areas for isotherms, dilution rates, and time of passage through plume. ` applicant’s physical models (from the ER), including - physical model facilities (e.g., dimensions of the plume and flow rates) - modeling techniques and scaling relationships - data collection and analysis techniques (e.g., number and locations of temperature probes, infrared mapping) October 1999 5.3.2.1-5 NUREG-1555 - prototype verification (if any) - the applicant’s flow fields and temperature distributions for critical and average hydrological conditions. II. ACCEPTANCE CRITERIA Acceptance criteria for the review of thermal impacts at the proposed plant sites are based on the relevant requirements of the following regulations: ` 33 CFR 322 with respect to definition of activities requiring permits ` 40 CFR 6, Appendix A, with respect to procedures on floodplain and wetlands protection ` 40 CFR 122 with respect to National Pollution Discharge Elimination System (NPDES) permit conditions for discharges ` 40 CFR 423 with respect to effluent limitations on existing and new point sources ` Federal, State, regional, local, and affected Native American tribal water laws and water rights. Regulatory positions and specific criteria necessary to meet the regulations as identified above are as follows: ` Compliance with environmental quality standards and requirements of the Federal Water Pollution Control Act (FWPCA), commonly referred to as the Clean Water Act, is not a substitute for and does not negate the requirement for NRC to weigh the environmental impacts of the proposed action, including any degradation of water quality, and to consider alternatives to the proposed action that are available for reducing the adverse impacts. If an environmental assessment of aquatic impacts is available from the permitting authority, the NRC will consider the assessment in its
