pecifications, and climate. The staff should determine applicability of the results of the generic environmental impact statement (GEIS) (NRC 1996) reviews of operational data to evaluation of impacts associated with heat dissipation to the atmosphere in environmental reviews by comparing the applicant’s plant design October 1999 5.3.3.1-5 NUREG-1555 and/or site environment with the ranges of designs and environments considered in the GEIS. The level of staff review of site/design specific data should be determined on the basis of the applicability of the conclusions in the GEIS and the conclusions reached in the GEIS. III. REVIEW PROCEDURES The reviewer should analyze the applicant’s estimates of the atmospheric effects of cooling system operation. The reviewer should consult with the reviewers for ESRPs 2.2.1, 2.5.3, and 3.1 to determine those locations for which analyses should be performed. (1) Evaluate the potential impacts on transportation caused by fogging and icing on the basis of the predicted additional hours of fogging and icing resulting from heat dissipation system. ` When these additional hours represent a significant fraction of the naturally occurring hours (determined by the reviewer for ESRP 2.7), and the affected transportation routes will be used by the general public, identify and evaluate means to mitigate the impact. (2) Compare predictions of the occurrence of plume interaction with ` existing pollutant sources ` weather modification in terms of cloud development ` shadowing ` humidity increases ` increased precipitation due to cooling tower plume or drift with operating experience at other sites. (3) Evaluate unusual heat dissipation system impacts (e.g., drift deposition on switch yards and other structures) not considered by the reviewers for ESRPs 5.1.1, 5.1.3, 5.3.3.2, and 5.8.1, and identify and evaluate means to avoid or mitigate any such impacts that are sufficiently adverse to warrant this action. (4) For spray canals, existing
